AIMS: To examine if personnel resources and organisational features in Swedish primary health-care centres (PHCCs) are associated to all-cause mortality (ACM) in people with type 2 diabetes mellitus (T2DM).

METHODS: A total of 187,570 people with T2DM registered in the Swedish National Diabetes Register (NDR) during 2013 were included in this nationwide cohort study. Individual NDR data were linked to data from a questionnaire addressing personnel resources and organisational features for 787 (68%) PHCCs as well as to individual data on socio-economic status and comorbidities. Furthermore, data on ACM were obtained and followed up until 30 January 2018. Hierarchical Cox regression analyses were applied.

RESULTS: After a median follow-up of 4.2 years, 27,136 (14.5%) participants had died. An association was found between number of whole-time-equivalent (WTE) general practitioner's (GP's) devoted to diabetes care/500 people with T2DM and lower risk of early death (hazard ratio 0.919 [95% confidence interval 0.895-0.945] per additional WTE GP; p = 0.002). No other personnel resources or organisational features were significantly associated with ACM.

CONCLUSIONS: This nationwide register-based cohort study suggests that the number of WTE GPs devoted to diabetes care have an impact on the risk of early death in people with T2DM.
