Health services utilization, satisfaction, and attachment to a regular source of care among participants in an urban health provider alliance.

This study examines the effect of a provider alliance on service utilization, satisfaction , self efficacy, and attachment to a regular source of care for participating low income urban children and their families. The use of Physician Assistants and community health workers to expand community outreach, primary care services, pediatric sub-specialty care, and service coordination within and between care settings improved health services utilization, satisfaction with health services, parental self efficacy in navigating the health care system for their children, and service convenience for an at-risk population. Also, the use of Physician Assistants to provide pediatric sub-specialty services did not have a negative effect on parental satisfaction with a child's care. Parents were slightly more satisfied with services received from a Physician Assistant in comparison with the physician sub- specialists in cardiology and nephrology clinics.
