How personnel diversity and affective bonds affect performance-based financing: a moderator analysis of a...

To spur improvement in health-care service quality and quantity, performance-based financing (PBF) is an increasingly common policy tool, especially in low- and middle-income countries. This study examines how personnel diversity and affective bonds in primary care clinics affect their ability to improve care quality in PBF arrangements. Leveraging data from a large-scale matched PBF intervention in Tajikistan including 208 primary care clinics, we examined how measures of personnel diversity (position and tenure variety) and affective bonds (mutual support and group pride) were associated with changes in the level and variability of clinical knowledge (diagnostic accuracy of 878 clinical vignettes) and care processes (completion of checklist items in 2485 instances of direct observations). We interacted the explanatory variables with exposure to PBF in cluster-robust, linear regressions to assess how these explanatory variables moderated the PBF treatment's association with clinical knowledge and care process improvements. Providers and facilities with higher group pride exhibited higher care process improvement (greater checklist item completion and lower variability of items completed). Personnel diversity and mutual support showed little significant associations with the outcomes. Organizational features of clinics exposed to PBF may help explain variation in outcomes and warrant further research and intervention in practice to identify and test opportunities to leverage them. Group pride may strengthen clinics' ability to improve care quality in PBF arrangements. Improving health-care facilities' pride may be an affordable and effective way to enhance health-care organization adaptation.
