Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Patients with chronic disease have regular visit to their physician in the Specialist Out-patient Clinic (SOPC) for follow-up.
For the intervention group, clinical pharmacist with 5 years of clinical experience will perform medication chart review prior to the next SOPC follow-up, The review includes assessing the appropriateness of each of the regular medications based on laboratory findings, medication lists, consultation and discharge notes, procedures and test results. Face-to-face interview (lasts for around 30-45 mins) will then be conducted with patients on the day prior to the SOPC follow-up. Clinical pharmacists will assess drug use history, identify drug-related problems and provide drug therapy interventions through written pharmacist note to physicians during the SOPC follow-up, based on the medication chart review and the above pharmaceutical assessments. Immediately after the SOPC follow up, clinical pharmacist will provide education (which lasts about 15 minutes) on drug-related problem identified before the visit, reinforce physician’s instruction, and encourage drug compliance using written patient educational leaflets. Phone follow follow-up will be conducted 1 month after the pharmacist intervention.
Written patient education leaflets were published by the Central Pharmacy Office, Hong Kong Hospital Authority.

Safety/efficacy
Statistical methods / analysis
The sample size calculation is based on previous study showing clinical pharmacist significantly reduced inappropriate prescribing. A sample size of 100 per arm is required to provide a 80% power using a two sided alpha-level of 0.05 to detect a mean difference in MAI of 0.4 between the intervention group and control group. Sample size is made up to 120 per arm to account for drop out.
For baseline characteristic, Wilcoxon rank sum test will be used for ordinal variables, and chi-square test will be used for categorical variables. Difference in MAI between the intervention group and control group will be compared by Student’s t-test.For other secondary outcome measurement with ordinal variables, Wilcoxon rank sum test will be used, and chi-square test for categorical variables. In all cases, 2-tailed P values of <0.05 will be considered statistically significant.
