Medication Review Improves Pain Management and Quality of Life in Chronic Pain

The MR arm will receive four MR interviews. In the first MR, information about the patient's personal and medical history, along with current health problems, relevant lab exams and medication will be gathered. This will be used to proceed with medication review process and assessment of Drug Related Problems (DRP) that may lead to negative medication results. A personalized care plan will be developed to correct any detected DRP, delivered in writing/e-mail to the patient and carefully explained. Some DRP's may need the physician's intervention to correct. In these cases, a detailed recommendation will be sent to the patient's physician via email. All physicians' recommendations acted upon or not, will be recorded. Subsequent interviews will assess patient compliance with the care plan and if necessary, adjustments will be made accordingly.

The UC arm will receive an intervention by the investigator at the same time frame defined for the MR arm. The intervention will also consist of interviews, although MR will not be conducted. The investigator will ask questions to the patient about is drug therapy in a similar fashion to what would happen in the community pharmacy. Simple advice and information will be carried out (i.e., reinforcement of adherence, explanation about indication of drugs etc.)
