Abstract

BACKGROUND:

Potentially inappropriate medications and prescription omissions (PO) are highly prevalent in older patients with mental comorbidities.

OBJECTIVE:

To evaluate the effect of interdisciplinary geriatric and psychiatric care on the appropriateness of prescribing.

DESIGN:

Prospective and interventional study.

SETTING:

Medical-psychiatric unit in an academic geriatric department.

PARTICIPANTS:

Participants were 150 consecutive acutely ill patients aged on average 80.0 ± 8.1 years suffering from mental comorbidities and hospitalized for any acute somatic condition.

INTERVENTION:

From admission to discharge, daily collaboration provided by senior geriatrician and psychiatrist working in a usual geriatric interdisciplinary care team.

MEASUREMENTS:

Potentially inappropriate medications and PO were detected and recorded by a trained independent investigator using STOPP/START criteria at admission and discharge.

RESULTS:

Compared with admission, the intervention reduced the total number of medications prescribed at discharge from 1347 to 790 (P < .0001) and incidence rates for potentially inappropriate medications and PO reduced from 77% to 19% (P < .0001) and from 65% to 11% (P < .0001), respectively. Independent predictive factors for PIP at discharge were being a faller (odds ratio [OR] 1.85; 95% confidence interval [CI] 1.43-2.09) and for PO, the increased number of medications (OR 1.54; 95% CI 1.13-1.89) and a Charlson comorbidity index greater than 2 (OR 1.85; 95% CI 1.38 - 2.13). Dementia and/or presence of psychiatric comorbidities were predictive factors for both potentially inappropriate medications and PO at discharge.

CONCLUSION:

These findings hold substantial promise for the prevention of IP and OP in such a comorbid and polymedicated population. Further evaluations are, however, still needed to determine if such an intervention reduces potentially inappropriate prescribing medication-related outcomes, such as incidence of adverse drug events, rehospitalization, or mortality.
