BACKGROUND:Patient satisfaction, one of the main components of quality of care, is a crucial phenomenon for the overall health care delivery system. Even though a number of studies have been conducted about patient satisfaction in different health services, studies in radiology services are flimsy in Ethiopia. This study aimed at assessing patient satisfaction towards radiological service and associated factors in Hawassa University Teaching and Referral hospital. METHODS:An institution based cross-sectional study was conducted among 321 adult patients presented for radiological service in the study area using stratified sampling technique. Patient satisfaction was measured using SERVQUAL (Service Quality) tool that consisted of seven items: accessibility, quality of radiological service, courtesy of radiology staff, existence of good communication with service provider and desk worker, physical environment and privacy technique. Exit interviews of patients were conducted using a structured and pretested questionnaire. Data was collected by three grade ten completed trained data collectors from May 12 to May 28, 2016. Multiple logistic regressions were used to identify independent factors associated with patient satisfaction on radiological services using SPSS version 21. RESULTS:The overall patient satisfaction towards radiological service was 71.6%. Satisfaction to accessibility of the service was 84.5% while it was 80.6% to courtesy of the staff. Similarly, 81.6% reported satisfied with quality of the service and 59.4% and 71% of reported satisfied with physical environment and radiological service provider respectively. On the other hand, 99.7% of the respondents were dissatisfied with privacy of the service. The study revealed that patients who attended primary school (AOR = 0.317, 95% CI: 0.11-0.88), unemployed patients (AOR = 0.067, 95% CI: 0.007-0.622) and patients who had short waiting time to enter into examination room less than one hour (AOR = 4.12, 95% CI: 1.4-11.62) were factors associated with patients satisfaction. CONCLUSION:This study found that majority of respondents was satisfied with the radiological services. Respondent's education level, occupation as well as duration of time taken to enter into examination room were important factors influencing the satisfaction condition. Hence, concerted effort is needed to constantly improve on patient satisfaction to better radiology returns arising from improved patient patronage. It is recommended to give great care and attention to clients during radiological examination procedure and also suggested that the department should decrease time taken to enter into examination room. On the other hand, the reasons behind more educated clients were less satisfied with radiologic service than more educated respondents need further investigation.
