    Prognostic Value of P-POSSUM and Osteopenia for Predicting Mortality After Emergency Laparotomy in Geriatric Patients2019Ingår i: Bulletin of emergency and trauma, ISSN 2322-2522, Vol. 7, nr 3, s. 223-231Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Objective: To evaluate the Portsmouth-Physiological and Operative Severity Score for the enUmeration of Mortality and morbidity (P-POSSUM) in comparison with other risk factors for mortality including osteopenia as an indicator for frailty in geriatric patients subjected to emergency laparotomy.

    Methods: All geriatric patients (≥65 years) undergoing emergency laparotomy at a single university hospital between 1/2015 and 12/2016 were included in this cohort study. Demographics and outcomes were retrospectively collected from medical records. Association between prognostic markers and 30-day mortality was assessed using Poisson and backward stepwise regression models. Prognostic value was assessed using receiver operating characteristic (ROC) curves.

    Results: =0.004) while osteopenia was not. P-POSSUM had poor prognostic value for 30-day mortality with an area under the ROC curve (AUC) of 0.59. The prognostic value of P-POSSUM improved significantly when adjusting for patient covariates (AUC=0.83).

    Conclusion: P-POSSUM and osteopenia alone hardly predict 30-day mortality in geriatric patients following emergency laparotomy. P-POSSUM adjusted for other patient covariates improves the prediction.

    Does beta-blockade reduce the risk of depression in patients with isolated severe extracranial injuries?2017Ingår i: World Journal of Surgery, ISSN 0364-2313, E-ISSN 1432-2323, Vol. 41, nr 7, s. 1801-1806Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    BACKGROUND: Approximately half of trauma patients develop post-traumatic depression. It is suggested that beta-blockade impairs trauma memory recollection, reducing depressive symptoms. This study investigates the effect of early beta-blockade on depression following severe traumatic injuries in patients without significant brain injury.

    METHODS: Patients were identified by retrospectively reviewing the trauma registry at an urban university hospital between 2007 and 2011. Severe extracranial injuries were defined as extracranial injuries with Abbreviated Injury Scale score ≥3, intracranial Abbreviated Injury Scale score <3 and an Injury Severity Score ≥16. In-hospital deaths and patients prescribed antidepressant therapy ≤1 year prior to admission were excluded. Patients were stratified into groups based on pre-admission beta-blocker status. The primary outcome was post-traumatic depression, defined as receiving antidepressants ≤1 year following trauma.

    RESULTS: Five hundred and ninety-six patients met the inclusion criteria with 11.4% prescribed pre-admission beta-blockade. Patients receiving beta-blockers were significantly older (57 ± 18 vs. 42 ± 17 years, p < 0.001) with lower Glasgow Coma Scale score (12 ± 3 vs. 14 ± 2, p < 0.001). The beta-blocked cohort spent significantly longer in hospital (21 ± 20 vs. 15 ± 17 days, p < 0.01) and intensive care (4 ± 7 vs. 3 ± 5 days, p = 0.01). A forward logistic regression model was applied and predicted lack of beta-blockade to be associated with increased risk of depression (OR 2.7, 95% CI 1.1-7.2, p = 0.04). After adjusting for group differences, patients lacking beta-blockers demonstrated an increased risk of depression (AOR 3.3, 95% CI 1.2-8.6, p = 0.02).

    CONCLUSIONS: Pre-admission beta-blockade is associated with a significantly reduced risk of depression following severe traumatic injury. Further investigation is needed to determine the beneficial effects of beta-blockade in these instances.

    Risk factors for depression following traumatic injury: An epidemiological study from a scandinavian trauma center2017Ingår i: Injury, ISSN 0020-1383, E-ISSN 1879-0267, Vol. 48, nr 5, s. 1082-1087Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    INTRODUCTION: A significant proportion of patients suffer depression following traumatic injuries. Once manifested, major depression is challenging to overcome and its presence risks impairing the potential for physical rehabilitation and functional recovery. Risk stratification for early detection and intervention in these instances is important. This study aims to investigate patient and injury characteristics associated with an increased risk for depression.

    METHODS: All patients with traumatic injuries were recruited from the trauma registry of an urban university hospital between 2007 and 2012. Patient and injury characteristics as well as outcomes were collected for analysis. Patients under the age of eighteen, prescribed antidepressants within one year of admission, in-hospital deaths and deaths within 30days of trauma were excluded. Pre- and post-admission antidepressant data was requested from the national drugs registry. Post-traumatic depression was defined as the prescription of antidepressants within one year of trauma. To isolate independent risk factors for depression a multivariable forward stepwise logistic regression model was deployed.

    RESULTS: A total of 5981 patients met the inclusion criteria of whom 9.2% (n=551) developed post-traumatic depression. The mean age of the cohort was 42 [standard deviation (SD) 18] years and 27.1% (n=1620) were females. The mean injury severity score was 9 (SD 9) with 18.4% (n=1100) of the patients assigned a score of at least 16. Six variables were identified as independent predictors for post-traumatic depression. Factors relating to the patient were female gender and age. Injury-specific variables were penetrating trauma and GCS score of≤8 on admission. Furthermore, intensive care admission and increasing hospital length of stay were predictors of depression.

    CONCLUSION: Several risk factors associated with the development of post-traumatic depression were identified. A better targeted in-hospital screening and patient-centered follow up can be offered taking these risk factors into consideration.

    Effect of beta-blocker therapy on early mortality after emergency colonic cancer surgery2019Ingår i: British Journal of Surgery, ISSN 0007-1323, E-ISSN 1365-2168, Vol. 106, nr 4, s. 477-483Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    BACKGROUND: Emergency colorectal cancer surgery is associated with significant mortality. Induced adrenergic hyperactivity is thought to be an important contributor. Downregulating the effects of circulating catecholamines may reduce the risk of adverse outcomes. This study assessed whether regular preoperative beta-blockade reduced mortality after emergency colonic cancer surgery.

    METHODS: This cohort study used the prospectively collected Swedish Colorectal Cancer Registry to recruit all adult patients requiring emergency colonic cancer surgery between 2011 and 2016. Patients were subdivided into those receiving regular beta-blocker therapy before surgery and those who were not (control). Demographics and clinical outcomes were compared. Risk factors for 30-day mortality were evaluated using Poisson regression analysis.

    RESULTS: A total of 3187 patients were included, of whom 685 (21·5 per cent) used regular beta-blocker therapy before surgery. The overall 30-day mortality rate was significantly reduced in the beta-blocker group compared with controls: 3·1 (95 per cent c.i. 1·9 to 4·7) versus 8·6 (7·6 to 9·8) per cent respectively (P < 0·001). Beta-blocker therapy was the only modifiable protective factor identified in multivariable analysis of 30-day all-cause mortality (incidence rate ratio 0·31, 95 per cent c.i. 0·20 to 0·47; P < 0·001) and was associated with a significant reduction in death of cardiovascular, respiratory, sepsis and multiple organ failure origin.

    CONCLUSION: Preoperative beta-blocker therapy may be associated with a reduction in 30-day mortality following emergency colonic cancer surgery.

    The Relationship Between Severe Complications, Beta-Blocker Therapy and Long-Term Survival Following Emergency Surgery for Colon Cancer2019Ingår i: World Journal of Surgery, ISSN 0364-2313, E-ISSN 1432-2323, Vol. 43, nr 10, s. 2527-2535Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    BACKGROUND: Emergency surgery for colon cancer carries significant morbidity, and studies show more than doubled mortality when comparing elective to emergency surgery. The relationship between postoperative complications and survival has been outlined. Beta-blocker therapy has been linked to improved postoperative outcomes. This study aims to assess the impact of postoperative complications on long-term survival following emergency surgery for colon cancer and to determine whether beta-blockade can reduce complications.

    STUDY DESIGN: This cohort study utilized the prospective Swedish Colorectal Cancer Registry to identify adults undergoing emergency colon cancer surgery between 2011 and 2016. Prescription data for preoperative beta-blocker therapy were collected from the national drug registry. Cox regression was used to evaluate the effect of beta-blocker exposure and complications on 1-year mortality, and Poisson regression was used to evaluate beta-blocker exposure in patients with major complications.

    RESULTS: A total of 3139 patients were included with a mean age of 73.1 [12.4] of which 671 (21.4%) were prescribed beta-blockers prior to surgery. Major complications occurred in 375 (11.9%) patients. Those suffering major complications showed a threefold increase in 1-year mortality (adjusted HR = 3.29; 95% CI 2.75-3.94; p < 0.001). Beta-blocker use was linked to a 60% risk reduction in 1-year mortality (adjusted HR = 0.40; 95% CI 0.26-0.62; p < 0.001) but did not show a statistically significant association with reductions in major complications (adjusted IRR = 0.77; 95% CI 0.59-1.00; p = 0.055).

    CONCLUSION: The development of major complications after emergency colon cancer surgery is associated with increased mortality during one year after surgery. Beta-blocker therapy may protect against postoperative complications.

    β-Blockade in Rectal Cancer Surgery: A Simple Measure of Improving Outcomes2020Ingår i: Annals of Surgery, ISSN 0003-4932, E-ISSN 1528-1140, Vol. 271, nr 1, s. 140-146Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    OBJECTIVE: To ascertain whether regular β-blocker exposure can improve short- and long-term outcomes after rectal cancer surgery.

    BACKGROUND: Surgery for rectal cancer is associated with substantial morbidity and mortality. There is increasing evidence to suggest that there is a survival benefit in patients exposed to β-blockers undergoing non-cardiac surgery. Studies investigating the effects on outcomes in patients subjected to surgery for rectal cancer are lacking.

    METHODS: All adult patients undergoing elective abdominal resection for rectal cancer over a 10-year period were recruited from the prospectively collected Swedish Colorectal Cancer Registry. Patients were subdivided according to preoperative β-blocker exposure status. Outcomes of interest were 30-day complications, 30-day cause-specific mortality, and 1-year all-cause mortality. The association between β-blocker use and outcomes were analyzed using Poisson regression model with robust standard errors for 30-day complications and cause-specific mortality. One-year survival was assessed using Cox proportional hazards regression model.

    RESULTS: A total of 11,966 patients were included in the current study, of whom 3513 (29.36%) were exposed to regular preoperative β-blockers. A significant decrease in 30-day mortality was detected (incidence rate ratio = 0.06, 95% confidence interval: 0.03-0.13, P < 0.001). Deaths of cardiovascular nature, respiratory origin, sepsis, and multiorgan failure were significantly lower in β-blocker users, as were the incidences in postoperative infection and anastomotic failure. The β-blocker positive group had significantly better survival up to 1 year postoperatively with a risk reduction of 57% (hazard ratio = 0.43, 95% confidence interval: 0.37-0.52, P < 0.001).

    CONCLUSIONS: Preoperative β-blocker use is strongly associated with improved survival and morbidity after abdominal resection for rectal cancer.

    Predicting In-Hospital and 1-Year Mortality in Geriatric Trauma Patients Using Geriatric Trauma Outcome Score2017Ingår i: Journal of the American College of Surgeons, ISSN 1072-7515, E-ISSN 1879-1190, Vol. 224, nr 3, s. 264-269Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background: The Geriatric Trauma Outcome Score, GTOS (= [age] + [Injury Severity Score (ISS)x2.5] + 22 [if packed red blood cells (PRBC) transfused ≤24hrs of admission]), was developed and validated as a prognostic indicator for in-hospital mortality in elderly trauma patients. However, GTOS neither provides information regarding post-discharge outcomes, nor discriminates between patients dying with and without care restrictions. Isolating the latter, GTOS prediction performance was examined during admission and 1-year post-discharge in a mature European trauma registry.

    Study Design: All trauma admissions ≥65years in a university hospital during 2007-2011 were considered. Data regarding age, ISS, PRBC transfusion ≤24hrs, therapy restrictions, discharge disposition and mortality were collected. In-hospital deaths with therapy restrictions and patients discharged to hospice were excluded. GTOS was the sole predictor in a logistic regression model estimating mortality probabilities. Performance of the model was assessed by misclassification rate, Brier score and area under the curve (AUC).

    Results: The study population was 1080 subjects with a median age of 75 years, mean ISS of 10 and PRBC transfused in 8.2%). In-hospital mortality was 14.9% and 7.7% after exclusions. Misclassification rate fell from 14% to 6.5%, Brier score from 0.09 to 0.05. AUC increased from 0.87 to 0.88. Equivalent values for the original GTOS sample were 9.8%, 0.07, and 0.87. One-year mortality follow-up showed a misclassification rate of 17.6%, and Brier score of 0.13.

    Conclusion: Excluding patients with care restrictions and discharged to hospice improved GTOS performance for in-hospital mortality prediction. GTOS is not adept at predicting 1-year mortality.

    The Association of Intracranial Pressure Monitoring and Mortality: A Propensity Score-Matched Cohort of Isolated Severe Blunt Traumatic Brain Injury2019Ingår i: Journal of Emergencies, Trauma and Shock, ISSN 0974-2700, E-ISSN 0974-519X, Vol. 12, nr 1, s. 18-22Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background: Intracranial pressure (ICP) monitoring in traumatic brain injury (TBI) is common. Yet, its efficacy varies between studies, and the actual effect on the outcome is debated. This study investigates the association of ICP monitoring and clinical outcome in patients with an isolated severe blunt TBI.

    Patients and Methods: Patients were recruited from the American College of Surgeons-Trauma Quality Improvement Program database during 2014. Inclusion criteria were limited to adult patients (>= 18 years) who had a sustained isolated severe intracranial injury (Abbreviated Injury Scale [AIS] head of >= 3 and Glasgow Coma Scale [GCS] of <= 8) following blunt trauma to the head. Patients with AIS score >0 for any extracranial body area were excluded. Patients' demographics, injury characteristics, interventions, and outcomes were collected for analysis. Patients receiving ICP monitoring were matched in a 1:1 ratio with controls who were not ICP monitored using propensity score matching.

    Results: A total of 3289 patients met inclusion criteria. Of these, 601 (18.3%) were ICP monitored. After propensity score matching, 557 pairs were available for analysis with a mean age of 44 (standard deviation 18) years and 80.2% of them were male. Median GCS on admission was 4[3,7], and a third of patients required neurosurgical intervention. There were no statistical differences in any variables included in the analysis between the ICP-monitored group and their matched counterparts. ICP-monitored patients required significantly longer intensive care unit and hospital length of stay and had an increased mortality risk with odds ratio of 1.6 (95% confidence interval: 1.1-2.5, P = 0.038).

    Conclusion: ICP monitoring is associated with increased in-hospital mortality in patients with an isolated severe TBI. Further investigation into which patients may benefit from this intervention is required.

    Does early beta-blockade in isolated severe traumatic brain injury reduce the risk of post traumatic depression?2017Ingår i: Injury, ISSN 0020-1383, E-ISSN 1879-0267, Vol. 48, nr 1, s. 101-105Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Introduction: Depressive symptoms occur in approximately half of trauma patients, negatively impacting on functional outcome and quality of life following severe head injury. Pontine noradrenaline has been shown to increase upon trauma and associated beta-adrenergic receptor activation appears to consolidate memory formation of traumatic events. Blocking adrenergic activity reduces physiological stress responses during recall of traumatic memories and impairs memory, implying a potential therapeutic role of beta-blockers. This study examines the effect of pre-admission beta-blockade on post-traumatic depression.

    Methods: All adult trauma patients (>= 18 years) with severe, isolated traumatic brain injury (intracranial Abbreviated Injury Scale score (AIS) >= 3 and extracranial AIS <3) were recruited from the trauma registry of an urban university hospital between 2007 and 2011. Exclusion criteria were in-hospital deaths and prescription of antidepressants up to one year prior to admission. Pre- and post-admission beta-blocker and antidepressant therapy data was requested from the national drugs registry. Post-traumatic depression was defined as the prescription of antidepressants within one year of trauma. Patients with and without pre-admission beta-blockers were matched 1: 1 by age, gender, Glasgow Coma Scale, Injury Severity Score and head AIS. Analysis was carried out using McNemar's and Student's t-test for categorical and continuous data, respectively.

    Results: A total of 545 patients met the study criteria. Of these, 15% (n = 80) were prescribed beta-blockers. After propensity matching, 80 matched pairs were analyzed. 33% (n = 26) of non beta-blocked patients developed post-traumatic depression, compared to only 18% (n = 14) in the beta-blocked group (p = 0.04). There were no significant differences in ICU (mean days: 5.8 (SD 10.5) vs. 5.6 (SD 7.2), p = 0.85) or hospital length of stay (mean days: 21 (SD 21) vs. 21 (SD 20), p = 0.94) between cohorts.

    Conclusion: beta-blockade appears to act prophylactically and significantly reduces the risk of posttraumatic depression in patients suffering from isolated severe traumatic brain injuries. Further prospective randomized studies are warranted to validate this finding.

    β-Blocker after severe traumatic brain injury is associated with better long-term functional outcome: a matched case control study2017Ingår i: European Journal of Trauma and Emergency Surgery, ISSN 1863-9933, E-ISSN 1863-9941, Vol. 43, nr 6, s. 783-789Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    PURPOSE: Severe traumatic brain injury (TBI) is the predominant cause of death and disability following trauma. Several studies have observed improved survival in TBI patients exposed to β-blockers, however, the effect on functional outcome is poorly documented.

    METHODS: Adult patients with severe TBI (head AIS ≥ 3) were identified from a prospectively collected TBI database over a 5-year period. Patients with neurosurgical ICU length of stay <48 h and those dying within 48 h of admission were excluded. Patients exposed to β-blockers ≤ 48 h after admission and who continued with treatment until discharge constituted β-blocked cases and were matched to non β-blocked controls using propensity score matching. The outcome of interest was Glasgow Outcome Scores (GOS), as a measure of functional outcome up to 12 months after injury. GOS ≤ 3 was considered a poor outcome. Bivariate analysis was deployed to determine differences between groups. Odds ratio and 95% CI were used to assess the effect of β-blockers on GOS.

    RESULTS: 362 patients met the inclusion criteria with 21% receiving β-blockers during admission. After propensity matching, 76 matched pairs were available for analysis. There were no statistical differences in any variables included in the analysis. Mean hospital length of stay was shorter in the β-blocked cases (18.0 vs. 26.8 days, p < 0.01). The risk of poor long-term functional outcome was more than doubled in non-β-blocked controls (OR 2.44, 95% CI 1.01-6.03, p = 0.03).

    CONCLUSION: Exposure to β-blockers in patients with severe TBI appears to improve functional outcome. Further prospective randomized trials are warranted.

    The Effect of Early Positive Cultures on Mortality in Ventilated Trauma Patients2018Ingår i: Surgical Infections, ISSN 1096-2964, E-ISSN 1557-8674, Vol. 19, nr 4, s. 410-416Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background: The purpose was to examine the incidence of positive cultures in a highly susceptible subset of trauma patients admitted to the surgical intensive care unit (SICU) for mechanical ventilation and to examine the impact of their timing on outcomes.

    Patients and Methods: A retrospective review was conducted of blunt trauma patients admitted to the SICU for mechanical ventilation at a level I trauma center over a five-year period. All urine, blood, and sputum cultures were abstracted. Patients with at least one positive culture were compared with those with negative or no cultures. The primary outcome was mortality. A Cox regression model with a time-dependent variable was utilized to calculate the adjusted hazard ratio (AHR).

    Results: The median age of 635 patients meeting inclusion criteria was 46 and 74.2% were male. A total of 298 patients (46.9%) had at least one positive culture, with 28.9% occurring within two days of admission. Patients with positive cultures were more likely to be severely injured with an injury severity score (ISS) 16 (68.5% vs. 45.1%, p<0.001). Overall mortality was 22%. Patients who had their first positive culture within two and three days from admission had a significantly higher AHR for mortality (AHR: 14.46, p<0.001 and AHR: 10.59, p=0.028, respectively) compared to patients with a positive culture at day six or later.

    Conclusions: Early positive cultures are common among trauma patients requiring mechanical ventilation and are associated with higher mortality. Early identification with damage control cultures obtained on admission to aid with early targeted treatment might be justified.

    Efficacy of beta-blockade after isolated blunt head injury: Does race matter? (vol 72, pg 1013, 2012)2012Ingår i: Journal of Trauma and Acute Care Surgery, ISSN 2163-0755, E-ISSN 2163-0763, Vol. 72, nr 6, s. 1725-1725Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    BACKGROUND: Several retrospective clinical studies and recent prospective animal models demonstrate improved outcomes with beta-blocker administration after isolated blunt head injury. However, no investigations to date have examined the influence of race on the potential therapeutic effectiveness of these medications. Our hypothesis was that mortality benefits associated with beta-blocker exposure after isolated blunt head injury varies based on ethnicity.

    METHODS: The trauma registry and the surgical intensive care unit (ICU) databases of an academic Level I trauma center were used to identify all patients sustaining blunt head injury requiring ICU admission from July 1998 to December 2009. Patients sustaining major associated extracranial injuries (Abbreviated Injury Scale [AIS] score ≥3 in any body region) were excluded. Patient demographics, injury profile, Injury Severity Score, and beta-blocker exposure were abstracted. The primary outcome evaluated was in-hospital mortality stratified by ethnicity.

    RESULTS: During the 11-year study period, 3,750 patients were admitted to the Los Angeles County + University of Southern California Medical Center trauma ICU because of blunt trauma. Of these, 65% (n = 2,446) had an “isolated” head injury. When stratified by race, most patients were Hispanics (60%), followed by Whites (21%), Asians (11%), and African Americans (8%). After adjusting for confounding variables with multivariate regression, only those of Asian and Hispanic descent demonstrated significantly improved outcomes associated with beta-blocker administration.

    CONCLUSIONS: Our results indicate that beta-blockade after traumatic brain injury may not benefit all races equally. Further prospective research is necessary to assess this discrepancy in treatment benefit and explore other possible therapeutic interventions.

    LEVEL OF EVIDENCE: III, therapeutic study; II, prognostic study.

    Early selenium treatment for traumatic brain injury: Does it improve survival and functional outcome?2017Ingår i: Injury, ISSN 0020-1383, E-ISSN 1879-0267, Vol. 48, nr 9, s. 1922-1926Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background: Traumatic brain injury (TBI) is a major cause of death and debility following trauma. The initial brain tissue insult is worsened by secondary reactive responses including oxidative stress reactions, inflammatory changes and subsequent permanent neurologic deficits. Effective agents to improve functional outcome and survival following TBI are scarce. Selenium is an antioxidant which has shown to reduce oxidative stress. This study examines the effect of intravenous selenium (Selenase (R)) treatment in patients with severe TBI on functional outcome and survival in a prospective study design.

    Methods: Patients sustaining TBI were prospectively identified during a 12-month period at an academic urban trauma center. Study inclusion criteria applied were: age >= 18 years, blunt injury mechanism and admission to neurosurgical intensive care unit (NICU). Early deaths (<= 48 h) and patients suffering extracranial injuries requiring invasive interventions or surgery were excluded. All consecutive admissions during a six-month period were administered intravenous Selenase (R) for a maximum 10-day period and constituted cases. Patient demographics and outcomes up to six-months post-discharge were collected for analysis.

    Results: A total of 307 patients met inclusion criteria of which 125 were administered Selenase (R). Stepwise Poisson regression analysis identified five common predictors of poor functional outcome and in-hospital mortality: GCS <= 8, age <= 55 years, hypotension at admission, high Rotterdam score and invasive neurosurgical intervention. Selenase (R) significantly reduced the risk of unfavourable functional outcomes, defined as GOS-E <= 4, at both discharge (adjusted RR 0.69, 95% CI 0.51-0.92, p = 0.012) and at six months follow-up (adjusted RR 0.61, 95% CI 0.44-0.83, p = 0.002). Following adjustment for significant group differences similar results were seen for functional outcome. Selenase (R) did not improve survival (adjusted RR 1.12, 95% CI 0.62-2.02, p = 0.709).

    Conclusion: Intravenous Selenase (R) treatment demonstrates a significant improvement in functional neurologic outcome. This effect is sustained at six months following discharge. (C) 2017 Elsevier Ltd. All rights reserved.

    Beta-Blocker Therapy in Severe Traumatic Brain Injury: A Prospective Randomized Controlled Trial2020Ingår i: World Journal of Surgery, ISSN 0364-2313, E-ISSN 1432-2323Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background: Observational studies have demonstrated improved outcomes in TBI patients receiving in-hospital beta-blockers. The aim of this study is to conduct a randomized controlled trial examining the effect of beta-blockers on outcomes in TBI patients.

    Methods: Adult patients with severe TBI (intracranial AIS >= 3) were included in the study. Hemodynamically stable patients at 24 h after injury were randomized to receive either 20 mg propranolol orally every 12 h up to 10 days or until discharge (BB+) or no propranolol (BB-). Outcomes of interest were in-hospital mortality and Glasgow Outcome Scale-Extended (GOS-E) score on discharge and at 6-month follow-up. Subgroup analysis including only isolated severe TBI (intracranial AIS >= 3 with extracranial AIS <= 2) was carried out. Poisson regression models were used.

    Results: Two hundred nineteen randomized patients of whom 45% received BB were analyzed. There were no significant demographic or clinical differences between BB+ and BB- cohorts. No significant difference in inhospital mortality (adj. IRR 0.6 [95% CI 0.3-1.4], p = 0.2) or long-term functional outcome was measured between the cohorts (p = 0.3). One hundred fifty-four patients suffered isolated severe TBI of whom 44% received BB. The BB? group had significantly lower mortality relative to the BB- group (18.6% vs. 4.4%, p = 0.012). On regression analysis, propranolol had a significant protective effect on in-hospital mortality (adj. IRR 0.32, p = 0.04) and functional outcome at 6-month follow-up (GOS-E >= 5 adj. IRR 1.2, p = 0.02).

    Conclusion: Propranolol decreases in-hospital mortality and improves long-term functional outcome in isolated severe TBI. This randomized trial speaks in favor of routine administration of beta-blocker therapy as part of a standardized neurointensive care protocol.

    Level of evidence: Level II; therapeutic.

    Study type: Therapeutic study.

    Beta-blocker Therapy is Associated with Decreased 1-year Mortality After Emergency Laparotomy in Geriatric Patients2019Ingår i: Scandinavian Journal of Surgery, ISSN 1457-4969, E-ISSN 1799-7267, artikel-id 1457496919877582Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    BACKGROUND AND AIMS: Emergency laparotomy is associated with a great risk of mortality in the elderly. The hyperadrenergic state induced by surgical trauma may play an important role in the pathophysiology of this increased risk. Studies have shown that beta-blocker exposure may be associated with decreased morbidity and mortality in the perioperative period. We aimed to study the effect of beta-blocker on mortality in geriatric patients undergoing emergency laparotomy.

    MATERIAL AND METHODS: ). The Poisson regression analysis was used to evaluate the association.

    RESULTS:  = 0.004). No significant differences in the incidence of post-operative complications between the two groups could be measured.

    CONCLUSION: Beta-blocker therapy may be associated with reduced 1-year mortality following emergency laparotomy in geriatric patients.

    Outcomes after resection versus non-resection management of penetrating grade III and IV pancreatic injury: A trauma quality improvement (TQIP) databank analysis2018Ingår i: Injury, ISSN 0020-1383, E-ISSN 1879-0267, Vol. 49, nr 1, s. 27-32Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    BACKGROUND: High-grade traumatic pancreatic injuries are associated with significant morbidity and mortality. Non-resection management is associated with fewer complications in pediatric patients. The present study evaluates outcomes following resection versus non-resection management of severe pancreatic injury caused by penetrating trauma.

    METHODS: A retrospective study of the Trauma Quality Improvement Program (TQIP) database was performed from 1/2010 to 12/2014. Patients with AAST Organ Injury Scale pancreatic grade III and IV injuries caused by penetrating trauma were included in the study. Demographics, vital signs on admission, Abbreviated Injury Scale per body region, Injury Severity Score, transfusion and therapeutic modality were obtained. Mortality, length of stay (LOS), pseudocyst, pancreatitis, sepsis, thromboembolism, renal failure, ARDS and unplanned ICU admission or re-operation were stratified according to injury grade and treatment modality. Patients were stratified into those who did/did not undergo pancreatic resection.

    RESULTS: A total of 4,098 patients had a pancreatic injury of which 15.9% (n=653) had a grade III and 6.7% (n=274) a grade IV pancreatic injury. There were no differences in patient demographics or overall injury severity between the resected and non-resected cohorts within each pancreatic injury grade. Forty-two percent of grade III and 38.0% of grade IV injuries underwent pancreatic resection. The total LOS was longer in the resection arm irrespective of pancreatic injury severity. There was no significant difference in morbidity between cohorts. Similarly, mortality was not significantly different between the two management approaches for grade III: 15.1% (95% CI 11.0-19.9) vs. 18.4% (95% CI 14.6-22.6), p=0.32 and grade IV: 24.0% (95% CI: 16.2-33.4) vs. 27.1% (95% CI: 20.5-34.4), p=0.68.

    CONCLUSION: Resection for treatment of grade III and IV pancreatic injury is not associated with a significant decrease in mortality but is associated with an increase in hospital LOS.

    Simultaneous common bile duct clearance and laparoscopic cholecystectomy: experience of a one-stage approach2019Ingår i: European Journal of Trauma and Emergency Surgery, ISSN 1863-9933, E-ISSN 1863-9941, Vol. 45, nr 2, s. 337-342Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Introduction: The timing and optimal method for common bile duct (CBD) clearance and laparoscopic cholecystectomy remains controversial. Several different approaches are available in clinical practice. The current study presents the experience of two European hospitals of simultaneous laparoscopic cholecystectomy (LC) and intra-operative endoscopic retrograde cholangiopacreatography (IO-ERCP) done by surgeons.

    Methods: Retrospective analysis of all consecutive patients subjected to LC+IO-ERCP during their index admission between 4/2014 and 9/2016. Data accrued included patient demographics, laboratory markers, operation time (min) reported as mean (SD) and hospital length of stay (LOS) reported as median (lower quartile, upper quartile).

    Results: During the 29-month study, a total of 201 consecutive LC+IO-ERCPs were performed. The mean age of patients was 55 +/- 19years and 67% were female. The mean intervention time was 105 +/- 44min. The total LOS was 4 (3, 7) days and the post-operative LOS was 2 (1, 3)days. A total of 6 (3%) patients experienced post-interventional pancreatitis and two (1%) patients suffered a Strasberg type A bile leak. All patients were successfully discharged.

    Conclusion: Simultaneous LC+IO-ERCP is associated with few complications. Further studies investigating cost-benefit and patient satisfaction are warranted.

    The Effect of beta-blockade on Survival After Isolated Severe Traumatic Brain Injury2015Ingår i: World Journal of Surgery, ISSN 0364-2313, E-ISSN 1432-2323, Vol. 39, nr 8, s. 2076-2083Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Several North American studies have observed survival benefit in patients exposed to beta-blockers following traumatic brain injury (TBI). The purpose of this study was to evaluate the effect of beta-blockade on mortality in a Swedish cohort of isolated severe TBI patients.

    The trauma registry of an urban academic trauma center was queried to identify patients with an isolated severe TBI between 1/2007 and 12/2011. Isolated severe TBI was defined as an intracranial injury with an Abbreviated Injury Scale (AIS) a parts per thousand yen3 excluding extra-cranial injuries AIS a parts per thousand yen3. Multivariable logistic regression analysis was used to determine the effect of beta-blocker exposure on mortality. Also, a subgroup analysis was performed to investigate the risk of mortality in patients on pre-admission beta-blocker versus not and the effect of specific type of beta-blocker on the overall outcome.

    Overall, 874 patients met the study criteria. Of these, 33 % (n = 287) were exposed to beta-blockers during their hospital admission. The exposed patients were older (62 +/- A 16 years vs. 49 +/- A 21 years, p < 0.001), and more severely injured based on their admission GCS, ISS, and head AIS scores (GCS a parts per thousand currency sign8: 32 % vs. 28 %, p = 0.007; ISS a parts per thousand yen16: 71 % vs. 59 %, p = 0.001; head AIS a parts per thousand yen4: 60 % vs. 45 %, p < 0.001). The crude mortality was higher in patients who did not receive beta-blockers (17 % vs. 11 %, p = 0.007) during their admission. After adjustment for significant confounders, the patients not exposed to beta-blockers had a 5-fold increased risk of in-hospital mortality (AOR 5.0, CI 95 % 2.7-8.5, p = 0.001). No difference in survival was noted in regards to the type of beta-blocker used. Subgroup analysis revealed a higher risk of mortality in patients naive to beta-blockers compared to those on pre-admission beta-blocker therapy (AOR 3.0 CI 95 % 1.2-7.1, p = 0.015).

    Beta-blocker exposure after isolated severe traumatic brain injury is associated with significantly improved survival. We also noted decreased mortality in patients on pre-admission beta-blocker therapy compared to patients naive to such treatment. Further prospective studies are warranted.

    Preinjury β-blockade is protective in isolated severe traumatic brain injury2014Ingår i: Journal of Trauma and Acute Care Surgery, ISSN 2163-0755, E-ISSN 2163-0763, Vol. 76, nr 3, s. 804-808Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background: The purpose of this study was to investigate the effect of preinjury β-blockade in patients experiencing isolated severe traumatic brain injury (TBI). We hypothesized that β-blockade before TBI is associated with improved survival.

    Methods: The trauma registry of an urban academic trauma center was queried to identify patients with an isolated severe TBI between January 2007 and December 2011. Isolated severe TBI was defined as an intracranial injury with an Abbreviated Injury Scale (AIS) score of 3 or greater excluding all extracranial injuries AIS score of 3 or greater. Patient demographics, clinical characteristics on admission, injury profile, Injury Severity Score (ISS), AIS score, in-hospital morbidity, and β-blocker exposure were abstracted for analysis. The primary outcome evaluated was in-hospital mortality stratified by preinjury β-blockade exposure.

    Results: Overall, a total of 662 patients met the study criteria. Of these, 25% (n = 159) were exposed to β-blockade before their traumatic insult. When comparing the demographics and injury characteristics between the groups, the sole difference was age, with the β-blocked group being older (69 [12] years vs. 63 [13] years, p < 0.001). β-blocked patients had a higher rate of infectious complications (30% vs. 19%, p = 0.04), with no difference in cardiac or pulmonary complications between the cohorts. Patients exposed to β-blockade versus no β-blockade experienced 13% and 22% mortality, respectively (p = 0.01). Stepwise logistic regression predicted the absence of β-blockade exposure as a risk factor for mortality (odds ratio, 2.7; 95% confidence interval, 1.5-4.8; p = 0.002). After adjustment for significant differences between the groups, patients not exposed to β-blockade experienced twofold increased risk of mortality (adjusted odds ratio, 2.2; 95% confidence interval, 1.3-3.7; p = 0.004).

    Conclusion: Preinjury β-blockade improves survival following isolated severe TBI. The role of prophylactic β-blockade and the timing of initiation of such therapy after TBI warrant further investigations.

    Level of evidence: Therapeutic study, level III; prognostic study, level II.

    Limited Effect of Beta-blockade on Postoperative Outcome After Laparoscopic Gastric Bypass Surgery2020Ingår i: Obesity Surgery, ISSN 0960-8923, E-ISSN 1708-0428, Vol. 30, nr 1, s. 139-145Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    BACKGROUND: The benefit of beta-blockade on postoperative outcome remains controversial, though recent studies have suggested a role during major non-cardiac surgery. The benefit of beta-blockade during minimally invasive gastric bypass surgery remains unclear. The aim of the present study was to evaluate the possible association between preoperative beta-blocker therapy and postoperative outcome after laparoscopic gastric bypass surgery.

    METHODS: Patients operated with primary laparoscopic gastric bypass surgery in Sweden between 2007 and 2017 were identified through the Scandinavian Obesity Surgery Registry. The dataset was linked to the Swedish National Patient Registry, the Swedish Prescribed Drug Registry, and Statistics Sweden. The main outcome was serious postoperative complication within 30 days of surgery; with postoperative complication, 90-day and 1-year mortality, and weight loss at 2 years after surgery as secondary endpoints. The Poisson regression model was used to evaluate primary and secondary categorical outcomes. A general mixed model was performed to evaluate 2-year weight loss.

    RESULTS: In all, 50281 patients were included in the study. No difference was seen between patients on beta-blockade and the control group regarding postoperative complications (adjusted incidence rate ratio 1.04 (95%CI 0.93-1.15), p = 0.506), serious postoperative complication (adjusted IRR 1.06 95%CI 0.89-1.27), p = 0.515), 90-day mortality (adjusted IRR 0.71 (95%CI 0.24-2.10), p = 0.537), and 1-year mortality (adjusted IRR 1.26 (95%CI 0.67-2.36), p = 0.467). Weight loss 2 years after surgery was slightly greater in patients on beta-blockade (adjusted coefficient 0.53 (95%CI 0.19-0.87), p = 0.002).

    CONCLUSIONS: Beta-blockade has limited impact on postoperative outcome after laparoscopic gastric bypass surgery.
