A stewardship program to facilitate anticholinergic and sedative medication deprescribing using the drug burden index in electronic medical records.

Aims: The drug burden index (DBI) measures a person's total exposure to anticholinergic and sedative medications, which are commonly associated with harm. Through incorporating the DBI in electronic medical records (eMR) and implementing a DBI stewardship program, we aimed to determine (i) uptake of the steward's recommendations to deprescribe anticholinergic and/or sedative drugs by the medical team and (ii) whether accepted recommendations were actioned in hospital or recommended for follow‐up by the General Practitioner post‐discharge. Methods: A single‐arm, non‐randomised feasibility study was performed at an Australian tertiary referral metropolitan hospital. The stewardship pharmacist reviewed eMRs of patients aged ≥75 years with DBI scores > 0, during admission. The steward identified and discussed potential opportunities to deprescribe anticholinergic and/or sedative medications with the medical registrars. Results: Amongst 256 patients reviewed, the steward made 170 recommendations for 117 patients. Registrars agreed with 141 recommendations (82.9%) for 95 patients (81.2%), and actioned 115 deprescribing recommendations for 80 patients, most commonly for antidepressants and opioids. The 115 actioned recommendations resulted in 125 changes, with 44 changes to the inpatient drug chart and 81 additional changes recommended post‐discharge in the discharge summary. Conclusion: Opportunities exist for deprescribing anticholinergic and sedative medications in older inpatients and a DBI stewardship program may help implement these. It is important to capture different outcomes of deprescribing interventions, including in‐hospital medication changes, recommendations in the Discharge Summary, sustainability of deprescribing and clinical outcomes.
