Integrated health intervention on polypharmacy and inappropriate prescribing in elderly people with multimorbidity: Results at the end of the intervention and at 6 months after the intervention

Background and objective: To analyse the impact of an integrated health intervention focused on polypharmacy and inappropriate prescribing (IP) in elderly people with multimorbidity. Material and methods: Patients were referred for assessment and intervention from primary care or hospital to an interdisciplinary team composed of primary and hospital medical staff and nurses. Pharmacological assessment was centred on polypharmacy and IP using the STOPP/START criteria. Changes in polypharmacy and in IP were analysed at the end of the intervention and at 6 months. Results: One hundred consecutive patients (mean (SD) age 81.5(8.0) years, 54(54%) male) were analysed. Mean prescribed medicines at baseline was > 10. There were no significant changes at the end of the intervention and at 6 months. The proportion of patients with two or more STOPP criteria reduced from 37% at the beginning of the intervention to 18% at the end (p<.001), and the proportion of those with START criteria from 13% to 6% (p = .004). These differences persisted at 6 months. The number of STOPP and START criteria before the intervention was associated with a decrease in the STOPP and START criteria at the end of the intervention and at 6 months. A reduction in polypharmacy (p=.041) and in falls (p=.034) was observed at 6 months in those with a decrease in the STOPP criteria at the end of the intervention. Conclusions: An integrated health intervention centred on polypharmacy and IP in elderly people improves inappropriate prescribing that persists beyond the intervention.

Automated summary

The study focused on analyzing the impact of an integrated health intervention on polypharmacy and inappropriate prescribing in elderly people with multimorbidity. The results showed a significant decrease in the proportion of patients with two or more STOPP criteria and START criteria at the end of the intervention and at 6 months. Patients who experienced a decrease in STOPP criteria also showed a reduction in polypharmacy and falls at 6 months.
