ObjectiveIn-hospital cardiac arrest is a critical medical emergency. Knowledge of prognostic factors could assist in cardiopulmonary resuscitation decision-making. Frailty and functional status are emerging risk factors and may play a role in prognostication. The objective was to evaluate the association between reduced mobility and in-hospital cardiac arrest outcomes.MethodsThis retrospective cohort study included patients over 18 years of age with in-hospital cardiac arrest in Botucatu, Brazil, from April 2018 to December 2021. Exclusion criteria were patients with a do-not-resuscitate order or patients with recurrent in-hospital cardiac arrest. Reduced mobility was defined as the need for a bed bath 48 h before in-hospital cardiac arrest. The outcomes of no return of spontaneous circulation and in-hospital mortality were evaluated.ResultsA total of 387 patients were included in the analysis. The mean age was 65.4±14.8 years; 53.7% were males and 75.4% had reduced mobility. Among the evaluated outcomes, the no return of spontaneous circulation rate was 57.1%, and in-hospital mortality was 94.3%. In multivariate analysis, reduced mobility was associated with no return of spontaneous circulation when adjusted by age, gender, initial shockable rhythm, duration of cardiopulmonary resuscitation, and epinephrine administration. However, in multiple logistic regression, there was no association between reduced mobility and in-hospital mortality.ConclusionIn patients with in-hospital cardiac arrest, reduced mobility is associated with no return of spontaneous circulation. However, there is no relation to in-hospital mortality.
