The investigators would thus like perform a randomized controlled trial to assess if a short course (for 6 weeks) out-patient PRP for patients admitted to acute hospital for AECOPD could have a positive impact on the patients by decreasing their health care resources utilization (recurrent COPD exacerbations, hospitalizations and accident and emergency department [AED] attendance) and improving the quality of life of the patients over a period of 1 year. Patients will be randomized to either a control group or PRP intervention group.
