The private health care services provider is faced with challenges of rising patients' expectations as a result of increasing patient awareness and increasing competition in the business environment. This has led to a shift to a customer focused approach where the involvement of the patient is critical for long term sustainability of the health care business. The purpose of this study was to assess perceived health care service quality, patient satisfaction and customer loyalty at Meridian Medical Centre. This was a cross sectional quantitative study. Sampling was through stratified random sampling. Data was collected using a self administered questionnaire that was completed by patients at the end of the outpatient visit. Data was coded and analysed using descriptive statistics and inferential statistics including correlations and ordinal regression to determine the relationships between the independent and dependent variables. The results showed that most patients perceived the quality of the health care services to be high, with assurance as the highest rated service dimension and responsiveness having the lowest rating. It was also found that there is a positive association between perceived service quality and both patient satisfaction and customer loyalty. The findings revealed that reliability, tangibles and responsiveness have a significant impact on patient satisfaction while reliability and tangibles significantly influence customer loyalty. The findings of this study will inform decision making by helping the management of Meridian Medical Centre to prioritize for quality improvement the dimensions of quality with the greatest impact on customer attraction and retention.
