In recent years, hospitals and payers have increased their efforts to improve the quality of patient care by encouraging provider adherence to evidence-based practices. Although the individual provider is certainly essential in the delivery of appropriate care, a team perspective is important when examining variation in quality. In the present study, the authors modeled the relationship between a measure of aggregate job satisfaction for members of primary care teams and objective measures of quality based on process indicators and intermediate outcomes. Multilevel analyses indicated that aggregate job satisfaction ratings were associated with higher values on both types of quality measures. Team-level job satisfaction ratings are a potentially important marker for the effectiveness of primary care teams in managing patient care.
