Low physical functioning and frailty are prevalent in non-geriatric vulnerable populations such as people experiencing homelessness, addiction and mental health challenges. The objective of this study was to explore the feasibility and impact of a targeted exercise intervention with protein supplementation for women experiencing homelessness, addiction and mental health challenges.

Mixed-methods feasibility study.

A women’s-only day service for people with homelessness and addiction issues, in Dublin, Ireland.

Women experiencing homelessness, addiction and mental health challenges.

The intervention was a 10-week low-threshold exercise and protein supplementation pre-post programme (LEAP-W). Qualitative interviews were conducted following the intervention with programme participants and key stakeholders.

The primary outcome was feasibility measured by recruitment, retention, adherence, safety and acceptability, and secondary outcomes measured pre-post intervention change in physical function, pain, nutritional and frailty status, and overall health status.

Overall, 33 participants were recruited. Data generated demonstrated that LEAP-W was feasible by its safety, acceptability and high retention in certain subgroups, and high adherence to the exercise and protein supplement; its impact was demonstrated by pre-post intervention improvement in multiple domains (strength (chair stand test), balance (the single leg stance test), pain and quality of life/mental health (mental component summary of the Short Form-12; 95% CI, p

Targeted exercise interventions with trauma-sensitive, flexible design can be successfully delivered and yield impact in women with complex needs who experience homelessness, addiction and mental health challenges. Service design should be considered when delivering interventions to this population. Further higher-powered longitudinal studies are warranted.

A retrospective cohort study.

A large multispecialty, tertiary referral and teaching hospital in England, UK.

The study included 3175 consecutive adult ICU UPAs from hospital wards over a 6-year period (2014–2019).

Ward-based management of deterioration prior to ICU admission was assessed by the RRT, using a scored checklist—the UPA score. Admissions were compared in two groups according to their exposure to an RRT review in the 72 hours before ICU admission. Associations with in-hospital cardiac arrest within 24 hours before ICU admission and all-cause in-hospital mortality were estimated, using unadjusted and adjusted odds ratios (aORs) with 95%CI.

RRT review occurred in 1413 (44.5%) admissions and was associated with reduced odds of in-hospital cardiac arrest (aOR 0.51; 95% CI 0.36 to 0.78; p

An RRT review in the 72 hours prior to ICU admission was associated with reduced odds of in-hospital cardiac arrest but did not impact in-hospital mortality. Higher UPA scores were associated with increased incidence of both in-hospital cardiac arrest and in-hospital mortality. In addition, this study describes a novel and adaptable RRT scoring tool (the UPA score) for safety monitoring and quality improvement.
