The complex phenomenon of polypharmacy in older age people of Greece: data from the new era of e-prescribing

Abstract

Background

Polypharmacy is a complex phenomenon with a number of negative effects.

Objective

The aim of this study was to investigate the prevalence and characteristics of simple (6–10 medicines/person), major (> 11), and excessive (> 21) polypharmacy in patients aged ≥ 60 years in the suburban older age population of Greece.

Methods

The prescribing records of 469 consecutive individuals, aged ≥ 60 years and with homogenous characteristics, who were clients of community pharmacies in two suburban areas of Greece (Athens and Thessaloniki) were examined over a period of 14 months. Medications used to treat chronic diseases were divided into 32 major categories and analyzed by age, sex, and medicine consumption.

Results

Polypharmacy was identified in 56.5% of patient records, with 48.8% of records identifying simple polypharmacy and the remaining 7.7% identifying major polypharmacy, with no cases of excessive polypharmacy. An increased usage of chronic drug treatment was observed in the older age groups relative to younger age groups (70.8% of patients aged > 80 years received polypharmacy vs 52.8 and 47.6% of those aged 70–79 and 60–69 years, respectively). The use of polypharmacy did not differ significantly between sexes. The use of chronic disease medication was higher for polypharmacy patients in all drug categories.

Conclusions

Polypharmacy in Greece, especially in older populations, still appears to be increasing, even in the era of e-prescriptions.
