Impact of a multidisciplinary approach involving clinical pharmacist on resolving drug related problems in chronic kidney patients: a prospective interventional study

Background Chronic kidney disease (CKD) is a major public health concern due to its high mortality risk, high hospitalization rates and cost, and low life expectancy. Thus, CKD patients are among patient group that may benefit from clinical pharmacy services the most. Methods This was a prospective interventional study conducted between October 1, 2019, and March 18, 2020, in the nephrology ward of Ankara University School of the Medicine, Ibn-i Sina Hospital. DRPs were classified according to PCNE v8.03. The main outcomes were interventions proposed and the rate of acceptance by the physicians. Results 269 pre-dialysis patients were included to determine DRPs during the treatment process of the patients. 205 DRPs were found in 131 (48.7%) patients. Treatment efficacy was found to be the main type of DRPs (56.2%) followed by treatment safety (39.6%). When patients with and without DRPs were compared, it was found that the number of female patients (55.0%) was higher in the group with DRPs (p < 0.05). The length of hospital stays (11.3 +/- 7.7) and the mean number of drugs used (9.6 +/- 3.6) in the group with DRPs were significantly higher than those without DRPs (9.3 +/- 5.9; 8.1 +/- 3.5, respectively) (p < 0.05). 91.7% of the interventions were accepted by the physicians, and patients and found clinically beneficial. 71.7% of DRPs were fully resolved, 1.9% partially resolved and 23.4% could not be resolved. Conclusions A high prevalence of DRPs in patients with chronic kidney disease was determined during therapy. Clinical pharmacist interventions were highly accepted by the physicians and patients. This may indicate implementation of clinical pharmacy services in the nephrology ward has a great impact on optimized therapy and prevention DRPs.
