Why Do We Need One DRP?

Decent Essays

Our study revealed that 82% of the participants had at least one drug related problem. The mean number of drug related problems was 1.65 ± 1.05. The most common drug related problems were need for additional drug therapy (29.35%), ineffective drug therapy (27.94%) and dose too low (15.8%). We found that 82% of the participants had at least one DRP. This finding is comparable with the report by Haugbolle et al (37) where 80.7% of participants had at least one DRP. similar finding was also noted in Adama, Ethiopia (38) where 80.7% of the participants had at least one DRP. However, the rate of DRPs in our set up is higher than the findings from India (39) where 71.1% of the patients had at least one DRP (mean 1.30± 1.10). This higher …show more content…

These findings are higher than the reports from Malaysia (19), India and Indonesia(16,33,34)(18)(40). The need for additional drug therapy in theses studies we compared ranged from 4.5%-15.61%. These variations may be due to differences in the tools used to classify drug related problems and study designs. Pharmaceutical Care Network Europe classification of DRPs was used to categorize DRPs in other studies while we used Cipoll’s drug related problem identification tool in our study. Differences in type 2 diabetes management guideline and the study settings might also be the possible reasons. For example, nearly 10% of type 2 diabetes patients with hypertension comorbidity in our set up received hydrochlorothiazide or Amilodipine while guidelines recommend the use angiotensin converting enzyme inhibitors, angiotensin recptor blockers or nondihydropyridine clacium channel blockers. This is because these class of drugs have renoprotective effect and reduce protein uria (41).The rate of ineffective drug therapy in our study is slightly lower than the study in Indonesia (42)where ineffective drug therapy was identified in 50% of the participants. In about 16% of the DRPS, the dose of drug was too low. This was in line with the study inThailand (43) and Ambo (44), Ethiopia, but higher than the reports from Malaysia, Indonesia and India ranging from 1.3%-12.92% (16,33,34). This discrepancy may be due to fact that all of
