A mixed method research design was used to answer the question; ‘does accreditation have an impact on hospital quality, clinical measures and patient experience?’ The thesis contains three study components: 1) A case study determining the predictors of patient experience; 2) a cross-sectional study examining the relationship of hospital accreditation and patient experience and 3) A four year time series analysis of the impact of accreditation on hospital quality using 27 quality measures. A case study analysis of patient experience, using a piloted, validated and reliable survey tool, was conducted in Al Noor Hospital. The survey was administered via face-to-face interviews to 391 patients. Patient demographic variables, stay characteristics and patient experience constructs were tested against five patient experience outcome measures using regression analysis. The predictors of positive patient experience were the patient demographics (age, nationality, and health status), hospital stay characteristics (length of stay and hospital treatment outcome) and patient experience constructs (care from nurses, care from doctors, cleanliness, pain management and quality of food). Recommendations were made on how hospital managers can improve patient experience using these modifiable factors. The cross-sectional study found that accredited hospitals had significantly higher inpatient experience scores than non-accredited hospitals. The hospital level variables, other than patient volume, had no correlations with patient experience. The interrupted time series analysis demonstrated that although accreditation improved the quality performance of the hospital with a residual benefit of 20 percentage points above the baseline level, this improvement was not sustained over the 3-year accreditation cycle. The accreditation life cycle theory was developed as an explanatory framework for the pattern of performance during the accreditation cycle. This theory was consequently supported by empirical evidence. Recommendations were made for improvement of the accreditation process. The Life Cycle Model and time series analysis were proposed as strategic tools for healthcare managers to recognise and prevent the negative trends of the accreditation life cycle in order to sustain improvements gained from accreditation. The findings of the three research components were triangulated to form a theory on the impact of accreditation on clinical quality measures and patient experience. This thesis is important from a research perspective, as healthcare accreditation, although commonly used to improve quality, is still under researched and under theorised. This is the first investigation of accreditation to use interrupted time series analysis, the first analysis on patient experience and hospital accreditation and also the first study on patient experience in the Middle East. Thus it adds to the evidence base of accreditation and patient experience but also has policy and management implications.
