A non-clinical randomised controlled trial to assess the impact of pharmaceutical care intervention on satisfaction level of newly diagnosed diabetes mellitus patients in a tertiary care teaching hospital in Nepal Health services research in low and middle income settings

Background: Patient satisfaction is the ultimate goal of healthcare system which can be achieved from good patient-healthcare professional relationship and quality of healthcare services provided. Study was conducted to determine the baseline satisfaction level of newly diagnosed diabetics and to explore the impact of pharmaceutical care intervention on patients' satisfaction during their follow-ups in a tertiary care teaching hospital in Nepal. Methods: An interventional, pre-post non-clinical randomised controlled study was designed among randomly distributed 162 [control group (n = 54), test 1 group (n = 54) and test 2 group (n = 54)] newly diagnosed diabetes mellitus patients by consecutive sampling method for 18 months. Diabetes Patient Satisfaction Questionnaire was used to evaluate patient's satisfaction scores at baseline, three, six, nine and, twelve months' follow-ups. Test groups patients were provided pharmaceutical care whereas control group patients only received their usual care from physician/nurses. The responses were entered in SPSS version 16. Data distribution was not normal on Kolmogorov-Smirnov test. Non-parametric tests i.e. Friedman test, Mann-Whitney U test and Wilcoxon signed rank test were used to find the differences among the groups before and after the intervention (p &0.05). Results: There were significant (p < 0.001) improvements in patients' satisfaction scores in the test groups on Friedman test. Mann-Whitney U test identified the significant differences in satisfaction scores between test 1 and test 2 groups, control and test 1 groups and, control and test 2 groups at 3-months (p = 0.008), (p <0.001) and (p < 0.001), 6-months (p = 0.010), (p<0.001) and (p<0.001), 9-months (p<0.001), (p<0.001) and (p<0.001) and, 12-months (p<0.001), (p<0.001) and (p
