Studies concerning pharmacist and COPD were identified to screen for randomized controlled studies that focused on pharmacist interventions for COPD at the hospital setting.Results: Twenty-nine studies were included in this review. The components of interventions identified were categorized according to the six service domains in the International Pharmaceutical Federation’s Basel Statements, and mainly concerned prescribing, preparation, administration and monitoring but not procurement and training. Extended interventions were also identified including life guidance, psychological counseling, and respiratory function exercise. The most common outputs reported were improvement in medication adherence, rational drug use, level of knowledge, and inhalation technique. The clinical outcomes (symptomatic control, lung function, rates of hospital readmission, length of hospital stay, and adverse drug adverse reactions), humanistic outcomes (quality of life and patient satisfaction), and economic outcomes (drug costs, hospitalization costs, antibiotic costs, and direct costs) were reported only in some studies. The contextual factors mainly included geographical factors, education level of patients, socio-economic factors, and no-smoking policy.Conclusion: The evidence for hospital pharmacists’ interventions in improving COPD patients’ outcome is growing. However, considering the challenges of COPD management, hospital pharmacists should further leverage the advantages of cross-sector and multi-disciplinary collaboration in order to provide more comprehensive support to better address the needs of their patients.Keywords: chronic obstructive pulmonary disease, hospital pharmacist, systematic review, intervention, output, outcome, logic model
