Adjusted linear models showed positive associations between physician FTEs per 1000 visits and cervical (\u03b2, 14.9; 95% CI, 3.1-26.7), breast (\u03b2, 15.7; 95% CI, 3.2-28.1), and colorectal (\u03b2, 18.3; 95% CI, 6.0-30.6) cancer screening. Generalized additive models showed nonlinear positive associations beginning at a physician FTE ratio of 0.45 (95% CI, 0.02-6.22) for infant vaccinations, 0.39 (95% CI, 0.05-2.21) for cervical cancer screening, 0.39 (95% CI, 0.02-1.67) for breast cancer screening, 0.47 (95% CI, 0.00-5.76) for HIV testing, and 0.70 (95% CI, 0.18-19.96) for depression in remission; APRN FTE ratio of 0.45 (95% CI, 0.17-7.46) for adult BMI assessment; and PA FTE ratio of 0.16 (95% CI, 0.11-3.88) for infant vaccinations.

These findings suggest that targeted staffing strategies may be associated with quality of care in certain domains and that tailored approaches to health center staffing based on community-specific needs are warranted.<\/jats:p><\/jats:sec>","DOI":"10.1001\/jamanetworkopen.2024.40140","type":"journal-article","created":{"date-parts":[[2024,10,22]],"date-time":"2024-10-22T15:07:54Z","timestamp":1729609674000},"page":"e2440140","source":"Crossref","is-referenced-by-count":10,"title":["Clinician Staffing and Quality of Care in US Health Centers"],"prefix":"10.1001","volume":"7","author":[{"given":"Q.
