Impact of Pharmaceutical Care on Drug-related Problems in Patients With Parkinson's Disease

Mahidol University80 enrolled

Overview

The aim of this study is to evaluate the impact of pharmaceutical care on the number of drug-related problems, clinical outcomes and quality of life of patients with Parkinson's disease.

This is a randomized controlled study that will be conducted in Parkinson's disease and movement disorders clinic, Siriraj Hospital, Thailand. The participants and assessors evaluating MDS-UPDRS were blinded in this study. The participants will be divided into two groups by block randomization: intervention group and usual care group. For the intervention group, the clinical pharmacists will conduct medication reviews, patient education, and counseling. Moreover, the clinical pharmacists will identify drug-related problems (DRPs) and provide the information through written pharmacist notes to physicians at the clinic. For patients randomized to the control group will attend the medical follow-up as usual and receive usual care. Telepharmacy will be conducted 2-7 days before the doctor visit and within 1 week after the doctor visit. Data collection will be conducted at baseline, week 12, and week 24 in both groups. After the follow-up, the pharmacist will count the number of drug-related problems identified after the doctor visit. The primary outcome of the study is comparing the number of drug-related problems per person changed from the start of the study to the end of week 24 between two groups.

Outcomes

Primary Outcomes

Change in the total number of drug-related problems related to all drugs

Compare the change of mean number of drug-related problems related to all drugs per person between the pharmaceutical care versus the usual care group.

Time frame: 24 weeks

Secondary Outcomes

Change in the number of drug-related problems related to with Parkinson's disease treatment

Compare the change of mean number of drug-related problems with Parkinson's disease treatment per person between the pharmaceutical care versus the usual care group.

Time frame: 24 weeks

Change in clinical outcome

Clinical outcome is assessed using Movement Disorder Society-Unified Parkinson's Disease Rating Scale (MDS-UPDRS) scores. Compare the change in MDS-UPDRS scores (both total score and separate part) between the pharmaceutical care group and the usual care group. The minimum and maximum value are 0 and 199, respectively. The higher scores mean a worse outcome.

Time frame: 12 and 24 weeks

Clinical status

Clinical status is assessed using Patient Global Impression of Change (PGIC). Compare the mean scores of PGIC at 12 and 24 weeks between the pharmaceutical care group and the usual care group. The minimum and maximum value are 1 and 7, respectively. The higher scores mean a worse outcome.

Time frame: 12 and 24 weeks

Change in Quality of life

Quality of life is assessed using the 8-item version of the Parkinson's Disease Questionnaire (PDQ-8). Compare the change in PDQ-8 scores between the pharmaceutical care group and the usual care group. The minimum and maximum value are 0 and 32, respectively. The higher scores mean a worse outcome.

Time frame: 24 weeks
