“…County-level factors include a binary indicator of metropolitan area, which has been both positively 16 and negatively 22 associated with financial performance; the per capita number of active nonfederal office-based physicians, which has been negatively associated with operating margin; 23 the number of short-term general hospitals and the number of FQHCs, which may drive demand and need for care as well as represent competition for the FQHC; and several measures of county demographics (percentage male, percentage non-white, percentage Hispanic) and socioeconomic status (per capita income, percentage uninsured, percentage unemployed), which have been negatively associated with FQHC financial performance. 20 Federally qualified health center-level factors include caseload, which has been positively associated with financial performance; 16 aggregate case-mix by age, gender, percentage non-white, and income (relative to the poverty level), which are likely to have a direct effect on organizational outcomes; a measure of chronic disease burden (percentage of encounters for diabetes, asthma, and/or hypertension), which has been negatively associated with financial performance; 16 the proportion of an FQHC's caseload by insurance status, which has been both positively 16,18 and negatively associated with financial performance; 24 board size, which has been negatively associated with consumer influence; 25 the number of delivery sites an FQHC operates, which may have implications for organizational outcomes (R. Wells, J. Vasey, F. Lawrence, and R. M. Politzer, unpublished data); the number of full-time equivalent staff, which has been negatively associated with operating margin; 24 and the number of physicians as a percentage of total staff, which has been positively associated with financial performance. 16 A binary variable is included to indicate the presence of at least one physician on the board, because boards with a physician presence may operate differently than boards without physicians.…”
