Knowledge on polypharmacy in a group of 65-year-old people or older living in a sector of the metropolitan area of Puerto Rico

Addressing the high utilization of medications among the elderly, this study explored the degree of knowledge of polypharmacy and its consequences, as well as the pattern of utilization by a group of elders 65 years of age and over in the San Juan metropolitan area of Puerto Rico. A dual technique was utilized: focus groups and a survey. Two focus groups were performed in order to explore issues pertaining the following domains: quality of life, doctor-patient and pharmacist-patient relationships, degree of knowledge of polypharmacy, and need of information. A questionnaire was administered to obtain information regarding their pattern of drug utilization. Results of focus groups indicated that the elderly have learned how to cope with their chronic conditions and be able to continue with quality of life. Additionally, results suggested a need form the elderly to develop more assertiveness and closeness with their health care providers, both doctor and pharmacist; as well as a lack of sufficient knowledge of the serious implications that polypharmacy brings. Results from the survey revealed and confirmed their inappropriate utilization of medications, and suggest that this segment consults multiple physicians, all of which may bring potential problems of adverse drug interactions. Further investigation is needed to examine fully the issue of polypharmacy, as well as the need of education that results in empowerment of patients, families and communities.
