RESUMEN
OBJECTIVES: Polypharmacy is a concern in the practice of geriatrics because of consequences such as adverse drug events and poorer quality of life. Deprescribing, a response to polypharmacy, refers to the systematic, programmed, and appropriate reduction in drug number and dose. Although now broadly recognized, challenges exist in practice for effective implementation. This study was conducted to determine the deprescribing success rate and relate it to drug classes and clinical settings, and to identify factors that influence the deprescribing process. DESIGN: As a performance improvement (PI) project, fellows in geriatric medicine, under supervision of faculty geriatricians, attempted deprescribing during at least 1 encounter daily at 2 long-term care (LTC) facilities and an outpatient geriatrics clinic (C) in Bronx, New York, from August 2018 to January 2019. Deprescribing was initiated following discussion and consent from patient or caregiver. Following the data collection, involved fellows and faculty physicians participated in a survey to identify factors that influenced the process. RESULTS: Out of 449 encounters, 383 encounters were included for analysis. Average patient age was 78.2 years (LTC: 77.9, C: 79.1). Average patient comorbidities was 6.5 (LTC: 6.7, C: 5.8). Deprescribing was successful in 90.1% of encounters (LTC: 96.9%, C: 67.4%). On average, 1.3 medications were deprescribed per encounter (LTC: 1.4, C: 1.0). Analgesics (32.2%), multivitamin-minerals supplements (29.7%), lipid-lowering agents (22.9%), antihistamines (46.7%), and acid blockers (26.2%) had highest success. CONCLUSIONS AND IMPLICATIONS: Deprescribing is possible in practice in both LTC and community settings at each encounter, until it is no longer applicable. Factors that contribute to successful deprescribing primarily include meaningful and earnest provider effort, ideally in collaboration with interdisciplinary team members (nurses, pharmacists, social worker, and others), besides interactions with consultants for the patient. Certain medication classes such as vitamins, minerals, analgesics, and proton pump inhibitors can be deprescribed with high success, as noted in our study, whereas antipsychotic agents, antidepressants, and ophthalmic preparations, prescribed by specialists, proved harder to deprescribe. An understanding of barriers to deprescribing (outlined in the article) and addressing them are crucial in enabling success. The study demonstrates that as a performance improvement project in collaborative effort with multiple disciplines, deprescribing is possible in health care. Factors promoting success and barriers to deprescribing are detailed. Appropriate deprescribing has the potential to help lower adverse drug events, costs of care, and possibly improve quality of life.

INTRODUCTION: Sliding scale insulin (SSI) therapy remains a common means of insulin therapy in long-term care (LTC) for the management of type 2 diabetes mellitus, despite current recommendations not supportive of the form of therapy today. Lack of randomized trial data on the efficacy and safety of basal-bolus insulin (B-BI) therapy in nursing home residents may have precluded this form of insulin administration in the LTC setting. Our study is a comparison of the efficacy of SSI (control) and B-BI (intervention) therapies during a 21-day intervention trial in older nursing home residents. METHODS: Fourteen LTC facilities in the US participated; 110 residents with type 2 diabetes volunteered to participate; 35 failed inclusion criteria, 75 signed informed written consent, and 11 were discharged to home/hospital or withdrew consent; data from 64 participants are reported. Recent fasting blood glucose (FBG), hemoglobin A1c, and chemistries were obtained. Four glucose readings (prior to breakfast, lunch, dinner, and bedtime), oral antiglycemic drug, and insulin doses and changes, and all adverse events/serious adverse events, both those related to glucose control [hypoglycemic (<70 mg/dL) and hyperglycemic (>200 mg/dL) episodes] and those unrelated, were recorded daily. Patients were randomized to either remain on SSI or be shifted to the B-BI group. RESULTS: Nursing home residents 80 ± 8 (standard deviation) years, 66% female participated; Control and Intervention participants had similar age, gender, race distributions, comorbidity, and 3-day average pretrial FBG levels (all P > .05). At study end, B-BI volunteers had significantly lower 3-day average FBG levels vs pretrial (P = .0231) while SSI participants had no change in 3-day average FBG (P > .05). During the trial, participants from both groups had similar rates of hypoglycemia, hyperglycemia, other adverse events, and hospitalizations (serious adverse events) unrelated to glucose control (all P > .05). CONCLUSIONS: B-BI therapy produced significantly lower average FBG levels after 21 days compared with SSI therapy; both groups had similar rates of hypo- and hyperglycemia. Switching to B-BI therapy is feasible, safe, and effective in the LTC setting.
