Associations between quality of work features in primary health care and glycaemic control in people with Type 2 diabetes mellitus: A nationwide survey

•Real life clinical data are needed to understand benefits of quality of work (QOW).•Examines associations between primary health care centres’ QOW and HbA1c levels.•An explorative factor analysis identified seven QOW features.•QOW involving an individualized treatment plan decreased HbA1c level in all groups.•More effective QOW strategies are needed to support people with uncontrolled HbA1c. To describe and analyse the associations between primary health care centres’ (PHCCs’) quality of work (QOW) and individual HbA1c levels in people with Type 2 diabetes mellitus (T2DM). This cross-sectional study invited all 1152 Swedish PHCCs to answer a questionnaire addressing QOW conditions. Clinical, socio-economic and comorbidity data for 230,958 people with T2DM were linked to data on QOW conditions for 846 (73.4%) PHCCs. Of the participants, 56% had controlled (≤52mmol/mol), 31.9% intermediate (53–69mmol/mol), and 12.1% uncontrolled (≥70mmol/mol) HbA1c. An explanatory factor analysis identified seven QOW features. The features having a call-recall system, having individualized treatment plans, PHCCs’ results always on the agenda, and having a follow-up strategy combined with taking responsibility of outcomes/results were associated with lower HbA1c levels in the controlled group (all p
