Supporting and retaining competent primary care workforce in low-resource settings: lessons learned from a prospective cohort study.

Objective: Assess whether local health facilities can adequately support the performance of general practitioners (GPs) trained by China's national compulsory services programme (CSP).

Design: Prospective cohort study.

Setting: Health facilities in middle and western rural areas in China, 2015-2022.

Participants: Cohorts of CSP graduates from 2015 to 2019 in four major medical universities.

Main outcomes: Job performance measured by a 12-item Job Performance Scale; productivity measured by outpatient volume per day; turnover measured by ever changing jobs within the past year.

Results: 91.2%, 92.0% and 90.5% GPs working in township health centres reported inadequate medication, equipment and external assistance from higher level hospitals, while CSP graduates working in secondary or tertiary hospitals reported a lower rate of less than 60%. The top three tests reported as lacking were blood gases (67.7%), microbiology (61.6%) and cancer biomarkers (49.7%); the top three lacked procedures were CT scan (64.8%), MRI scan (58.1%) and ambulatory BP monitoring (55.8%); and the top three lacked drugs were drugs for cardiovascular diseases (23.3%), systematic hormonal preparations (17.7%) and traditional Chinese medicines (13.0%). Multivariable analysis showed that facility support was positively associated with job performance-adequate medication increased job performance by 2.2 points (95% CI 0.7 to 3.8), and adequate external assistance increased job performance by 3.3 points (95% CI 1.8 to 4.8). Facility support was also positively associated with productivity-adequate medication increased outpatients seen per day by 20% (95% CI 0.1 to 0.3), and adequate equipment increased outpatients seen per day by 12% (95% CI 0.0 to 0.2). Facility support did not have significant impact on turnover, but GPs who changed jobs in the past year were 1.9-2.3 times more likely to report adequate facility support.

Conclusion: GPs in township health centres experienced a high prevalence of shortage in facility support. The identification of a positive association between facility support and performance and productivity has implications for future research and resources deployment in primary healthcare.
