Case: Mid-shift, you realise that the next patient you are about to see is the third in a row aged over 70 who has fallen at home, and that this is her third attendance for a fall in the last two months. You wonder if any emergency department (ED)-based interventions would help her and people like her be safe.
Background: We looked at geriatric falls on an SGEM Xtra in 2015. Back then we found that at one academic site older adults attending ED with falls didn't receive guideline-based assessment, risk stratification or management.

In 2014 the SGEM looked at a systematic review by Dr. Chris Carpenter, which concluded that there wasn't a good tool to help us predict which ED patients are at risk of recurrent falls (SGEM #89).
Close to three million adults aged 65 and over visit American EDs annually after a fall [1]. Falling is the most common cause of traumatic injury resulting in older adults presenting to the ED [2]. Approximately 20% of falls result in injuries, and falls are the leading cause of traumatic mortality in this age group [3-5].
The SAEM Geriatric Emergency Medicine Task Force recognized fall prevention as a priority over 10 years ago. There is the Geriatric Emergency care Applied Research (GEAR) network, which is trying to improve the emergency care of older adults and those with dementia and other cognitive impairments. GEAR looks to identify research gaps in geriatric emergency care support research and evaluation of these areas. GEAR 2.0 has recently been launched with funding opportunity in conjunction with EMF.
There are three other GEAR 1.0 manuscripts which have been published:

Clinical Question: In older patients presenting to ED with falls do risk stratification or fall prevention interventions influence patient-centered or operational outcomes?

This publication presents two related but different scoping reviews so there are two PICOs.
PICO #1
Population: Systematic search that found 32 studies of fall prevention interventions for patients aged 60 or over who presented to ED with a fall.
Exclusions: Abstracts repeating data already included in full, not original research.
Intervention: Fall prevention interventions including multifactorial risk reduction, medication review, exercise training, models of care like Hospital-at-Home.
Comparison: Standard of Care.
Outcomes: Quality of care ED metrics, ED operational outcomes like length of stay, patient-centered outcomes like ED returns, further falls, fear of falling, functional decline, institutionalization.
PICO #2
Population: Systematic search that found 17 studies of risk stratification and falls care plans in patients aged 60 or over in ED or pre-ED settings.
Exclusions: As review 1.
Intervention: Risk stratification and falls care plan.
Comparison: No risk stratification and falls care plan.
Outcomes: ED referral (from pre-ED setting), quality of care ED metrics, ED operational outcomes, patient-centered outcomes.
This is an SGEMHOP episode which means we have the honour of having the lead author, Dr. Elizabeth (Liz) Goldberg, on the show. She is an Associate Professor of Emergency Medicine and Health Services, Policy and Practice at Brown University. Her specific areas of interest include improving care for older adults and public health interventions to enhance longevity and healthy aging.

Authors’ Conclusions: “Harmonizing definitions, research methods, and outcomes is needed for direct comparison of studies. The need to identify ED-appropriate fall risk assessment tools and role of emergency medical services (EMS) personnel persists. Multifactorial interventions, especially involving exercise, are more efficacious in reducing recurrent falls, but more studies are needed to compare appropriate bundle combinations. GEAR prioritizes five research priorities: (1) EMS role in improving fall-related outcomes, (2) identifying optimal ED fall assessment tools, (3) clarifying patient-prioritized fall interventions and outcomes, (4) standardizing uniform fall ascertainment and measured outcomes, and (5) exploring ideal intervention components.”
Quality Checklist for Scoping Systematic Reviews:

Results: 32 studies were included (3 meta-analyses and 23 RCTs) with a total of 571,071 patients to try to answer the first PICO question about falls prevention. Studies were from 11 countries, 1999-2019, with follow-up from 1 to 18 months. Interventions included falls risk assessment, physical rehabilitation sessions, preventive education, educational guidelines, follow-up with NP or PT, and alert devices. Most used recurrent falls as the outcome although anxiety over falls, functional ability and QALYs also featured.
17 studies were included (4 meta-analyses and 8 RCTs) with a total of at least 17,232 patients to address the second PICO question about risk stratification. Studies were from 9 countries, 2011-18, with follow-up from 6 to 12 months. 11 screening instruments were identified with interventions including educational, physical therapy, follow-up calls, discharge planning and home visits. Most used recurrent falls as the outcome.
Key Result: The GEAR-Falls group identified five research priorities.
EMS role in improving fall-related outcomes
Identifying optimal ED fall assessment tools
Clarifying patient-prioritized fall interventions and outcomes
Standardizing uniform fall ascertainment and measured outcomes
Exploring ideal intervention components
We asked Liz five nerdy questions about her study. Listen to the SGEM podcast to hear her responses.
1. Question Selection: Your group original had three PICO questions (the third was about specific risk factors for falls e.g. polypharmacy). How and why did you decide to address the two that you did?
2. Consensus Conference: You held a consensus conference of your multidisciplinary group with the initial findings of the scoping review to generate and vote on research priorities.
