A Novel Design for an Emergency Department Virtual Observation Fall Prevention Program

About 36 million falls are reported among older adults each year—resulting in more than 34,000 deaths. These falls are costly, and they account for numerous emergency department (ED) visits. Because of crowding, ED staff often miss the opportunity to focus on preventing additional falls. Recognizing the urgency of the problem, and in an attempt to save lives, MGH’s ED recently opened a Virtual Observation Unit (VOU) that provides observation-level care for ED patients in the comfort of their home. This program includes VOU (ED) nurses who assess patients via phone or video, community paramedics who visit patients in their home, and emergency medicine physicians who conduct video visits.

Building on the early success of the MGH VOU program and given the lack of ED fall prevention programs nationwide, Liu’s team proposes to pilot a replicable ED VOU falls program that would: allow ED fall patients who have had an evaluation in the ED to return home if they are deemed safe to do so; perform a home safety evaluation; determine if they require physical therapy; and assess if patients have medications that could increase their risk of falling.

With funding from the Stepping Strong Center, Liu will assess if this program is safe, feasible and acceptable. If the pilot program is successful, she will expand the program to other Mass General Brigham EDs, partner with fall detection device companies, and potentially have certain fall patients evaluated for their falls in their home, avoiding the ED altogether. The overall goal of the program is to decrease the risk of an older person falling again, thus reducing the likelihood of serious injury and death related to falls.
