Effectiveness of clinical pharmacist intervention on health-related quality of life in chronic obstructive pulmonary disorder patients - a randomized controlled study

What is known and objectiveChronic obstructive pulmonary disease (COPD), a preventable and treatable disease, has been described as 10% medication and 90% education'. Extreme physician scarcity limits the implementation of quality healthcare delivery in India. We conducted this study to evaluate the effectiveness of clinical pharmacist intervention on health-related quality of life (HRQoL) in patients with COPD in an Indian tertiary care hospital. MethodsAn open-labelled randomized controlled study was conducted over a 3-year period, at Kasturba Medical College Hospital, Manipal, India, after obtaining institutional ethics clearance (IEC 88/2012). The study was registered with the Indian clinical trial registry (CTRI/2014/08/004848). Patients were randomly assigned to two groups (intervention group [IG] and control group [CG]) by envelope method. St. George's Respiratory Questionnaire (SGRQ) was used to assess the HRQoL. The pharmacist intervention laid emphasis on (i) importance of medication compliance, (ii) need for smoking cessation, (iii) simple exercise, (iv) proper use of inhaler devices and (v) need for timely follow-up by pulmonary medicine department. SGRQ assessment was repeated at 6, 12, 18 and 24 months. ResultsOf 328 patients with COPD screened during the study period (March 2012 to June 2013), 260 (79%) were recruited. Of these, 202 (78%) patients completed follow-up (98 in CG and 104 in IG). Both groups were matched for baseline, sociodemographics and clinical characteristics. SGRQ scores and its subscales (symptoms, activity and impact) improved significantly after the pharmacist intervention in IG at follow-up (P < 0001). What is new and conclusionOur randomized controlled study shows that pharmacist intervention improved the HRQoL of patients with COPD in India. The generalizability of our results requires exploration even within other settings in India. Nonetheless, our results provide support for a greater involvement of pharmacists in the care of patients with COPD.
