Physicians' role in the development of inappropriate polypharmacy among older adults in Iran: a qualitative study

The use of unnecessary or excessive medications (inappropriate polypharmacy) is a major health challenge among older adults which is driven by several factors. This study aims to provide in-depth descriptions of the physician's role in the development of inappropriate polypharmacy among older adults in Iran.

Qualitative content analysis of interviews, field notes and other relevant documents available (eg, medical records). Data collection and analyses were done concurrently to guide the sampling process.

Three purposively selected referral hospitals in Tehran, Iran.

A total of 7 physicians, 10 older adults, 3 caregivers and 3 pharmacists with a median age of 54 (IQR 23) years were recruited through convenience sampling.

Emerged categories included misdiagnosis, inappropriate prescribing, insufficient patient education, poor communication, unprofessional behaviour and limited perspectives which highlight the role of physicians in the development of inappropriate polypharmacy among older adults in Iran under the main concept of poor medical practice.

This study provides valuable insight on the role of physicians in the development of inappropriate polypharmacy among the elderly in the healthcare setting in Iran by exploring the viewpoints of physicians, patients, caregivers and pharmacists. Physicians can be an influential factor in tackling this challenge through proper diagnosis, prescription, patient education and follow-up. In Iran, physicians' practice styles are affected by potentially adverse factors such as the novelty of geriatric medicine, lack of a referral system, patient unfamiliarity with the system and lack of a monitoring system for multiple prescriptions. Furthermore, clinics tend to be overcrowded and visit fees can be low; in this setting, lack of physician assistants leads to limited time allocation to each patient and physician dissatisfaction with their income.
