Involvement of the private sector in provision of health services has progressively increasedrnin many developing countries including Ethiopia. Promotion of the private sectorrninvolvement is also one of the health care financing strategy in Ethiopia.rnA cross sectional descriptive study was done on Quality of Care in private clinics in AddisrnAbaba in April, 2000. Different levels of clinics were randomly selected and assessmentsrnwere done on structural aspects, performance of health workers in polyclinic outpatientrndepartment and patients satisfaction with the different aspects of care given.rnIt was found that most clinics fulfill the structural requirements of the MOH with regard tornsta ffing, equipment and medications. Neverthless few clinics were found not to fulfill thernminimum requirements put in the guideline. With regard to performance, various aspects ofrnmalperformance were observed where the highest problem was concerning treatments givenrnto patients.Thirty seven percent of treatments given to patients were rated to bernunacceptable. Over prescription of antibiotics and injections was also found specially inrnsmall clinics. Patients were generally satisfied in all aspects of medical care where highestrnsatisfaction was in relation to courtesy of providers and relatively lower satisfaction withrncost.rnFindings are discussed in comparision with findings in public and private health facilities inrnEthiopia and other countries.
