BackgroundHow can psychiatrists best provide care in complex, sometimes overwhelming disasters? COVID-19 strained every aspect of health care to the breaking point, from finances to pharmaceutical supply lines. We can expect more challenges to prescribing in the future, as shown by recent hurricanes in Puerto Rico, fires in California, and ice storms in Texas. When medications become scarce or inaccessible, then clinicians need to make difficult prescribing decisions. We suggest that a culture of deprescribing, a systematic approach to reducing or simplifying medications, could be applied to a wide variety of crises. Deprescribing is defined as the planned reduction of medications to improve patient health or to reduce side effects (see deprescribing.org). It has been used to reduce polypharmacy in geriatric and other complex populations. It provides evidence-based guidance for phasing out many classes of medications. It is part of the larger program to reduce waste in health care and to make pharmacy more rational. Disasters and resource scarcity, however, require a different approach. In contrast to routine care focused on individual patients, crisis standards of care (CSC) shift the clinical focus to the community. Instead of deprescribing guidelines for individual clinicians, CSC deprescribing would be national policies addressing shortages of important medications. We did a scoping review looking for studies of deprescribing in a crisis.
Methods/ResultsWe extracted 1340 references in Google Scholar 2016 to 2021 using (deprescribing) AND (disaster OR crisis OR climate OR pandemic OR supply lines). A scan of texts found 160 references matching our criteria, and only 19 of them addressed deprescribing as a strategy to strengthen health systems or providers in an emergency. Most of those were related to scarce supplies during COVID, and a few addressed the carbon impact of medications. We also reviewed related literatures on medication supply chain vulnerabilities, WHO Essential Medicines, and healthcare rationing.
ImplicationsDeprescribing gained attention during the COVID pandemic, responding to both disrupted supply lines and improving patient safety. Writers concerned with climate change support deprescribing to reduce the carbon impact of medications. Deprescribing as crisis policy could help streamline national stockpiles, supply chains, and manufacturing. Education could make deprescribing second nature for clinicians, potentially decreasing stress and increasing flexibility in future emergencies. Barriers to deprescribing generally include cultural inertia, industry lobbyists, education, and malpractice fears. In a crisis, deprescribing guidelines could provide clinicians with confidence and flexibility while conserving scarce resources. Research is needed to evaluate deprescribing guidelines for crises, especially ensuring equity in how they reduce polypharmacy and save money.
