Perspectives of health professionals on physical activity and sedentary behaviour in hospitalised adults: A systematic review and thematic synthesis

Interventions to Promote Physical Activity and Reduce Functional Decline in Medical Inpatients: An Umbrella Review

OBJECTIVES

Physical inactivity in hospitals is common and is associated with poor patient and clinical outcomes. This review was undertaken to identify and describe the effectiveness of interventions implemented at the ward or system level for improving physical activity and reducing functional decline in general medical inpatients. The secondary aim was to describe the effects on length of stay, discharge destination, falls, and hospital costs.

DESIGN

Umbrella review.

SETTING AND PARTICIPANTS

Systematic reviews that evaluated ward- or system-level interventions aiming to improve physical activity or reduce functional decline in medical inpatients.

METHODS

PubMed, EMBASE, Cochrane Database, CINAHL, JBI, and Web of Science databases were searched for English-language reviews published between 2000 and 2023. AMSTAR 2 was used to assess methodologic quality. Two reviewers independently assessed eligibility and methodologic quality and completed data abstraction, with results presented as a narrative synthesis.

RESULTS

The search yielded 568 systematic reviews of which 12 met criteria, half of which were published since 2020. Reviews included 76 unique primary studies with 72,645 participants. Most reviews were of low quality. Interventions that focused on progressive mobilization likely increased physical activity participation, reduced functional decline, and improved discharge home. Multicomponent interventions that employed multiple strategies targeting a broader range of barriers likely improved functional decline and discharge home and may have been associated with shorter length of stay. No interventions were associated with increased frequency of falls. Few studies reported costs.

CONCLUSIONS AND IMPLICATIONS

Progressive mobilization interventions and multicomponent interventions appear to be effective for improving physical activity participation and reducing functional decline in medical inpatients. Further high-quality studies may help to determine the most important aspects of multicomponent interventions. Standardized terminology related to inpatient physical activity may help promote a shared understanding and purpose across professions.

The influence of hospital and home environments on physical activity and sedentary behaviour: Perceptions of people recovering from fractures

BACKGROUND

A lack of evidence exists contrasting the factors that influence physical activity and sedentary behaviour in both hospital and home settings before and after discharge from acute hospitalisation for fractures.

OBJECTIVE

To describe and compare perceptions of environmental influences on physical activity in hospital and home settings in people recovering from fractures.

METHOD

Semi-structured interviews were conducted with patients hospitalised following fractures (hip fracture or multi-trauma), exploring the barriers and enablers to physical activity within hospital and home settings. Interviews were conducted within two weeks of hospital discharge, audio recorded and transcribed prior to thematic analysis via a framework approach.

RESULTS

Between December 2022 and May 2023, 12 semi-structured interviews were undertaken with an equal number of participants who sustained an isolated hip fracture or multi-trauma. The median (IQR) age of participants was 60 (52-68) years, with half being male, and the majority sustaining their injuries via transport crashes. Three main themes that influenced physical activity behaviours in hospital and home settings were: having the opportunity, having a reason, and having support and assistance to be active.

CONCLUSION

During the period of reduced physical capability following fracture, patients need to be provided with opportunities and motivation to be active, particularly within the hospital setting. Findings from this study will assist clinicians to better support people recovering from fractures via greater engagement in physical activity within hospital and home settings.

The Wearable Activity Tracker Checklist for Healthcare (WATCH): a 12-point guide for the implementation of wearable activity trackers in healthcare

Increasing physical activity in patients offers dual benefits, fostering improved patient health and recovery, while also bolstering healthcare system efficiency by minimizing costs related to extended hospital stays, complications, and readmissions. Wearable activity trackers offer valuable opportunities to enhance physical activity across various healthcare settings and among different patient groups. However, their integration into healthcare faces multiple implementation challenges related to the devices themselves, patients, clinicians, and systemic factors. This article presents the Wearable Activity Tracker Checklist for Healthcare (WATCH), which was recently developed through an international Delphi study. The WATCH provides a comprehensive framework for implementation and evaluation of wearable activity trackers in healthcare. It covers the purpose and setting for usage; patient, provider, and support personnel roles; selection of relevant metrics; device specifications; procedural steps for issuance and maintenance; data management; timelines; necessary adaptations for specific scenarios; and essential resources (such as education and training) for effective implementation. The WATCH is designed to support the implementation of wearable activity trackers across a wide range of healthcare populations and settings, and in those with varied levels of experience. The overarching goal is to support broader, sustained, and systematic use of wearable activity trackers in healthcare, therefore fostering enhanced physical activity promotion and improved patient outcomes.

Associations Between Inactivity and Cognitive Function in Older Intensive Care Unit Survivors

BACKGROUND/INTRODUCTION

Critically ill older adults are profoundly inactive while in the intensive care unit (ICU), and this inactivity persists after discharge from the ICU. Older ICU survivors who were mechanically ventilated are at high risk for post-ICU cognitive impairment.

OBJECTIVES/AIMS

The present study examined the relationship between the ratio of daytime to nighttime activity and executive function in older ICU survivors.

METHODS

This was a secondary analysis of pooled data from 2 primary studies of older adults who were functionally independent prior to hospitalization, mechanically ventilated while in ICU, and within 24 to 48 hours post-ICU discharge. Actigraphy recorded daytime activity (mean activity counts per minute, 6 am to 9:59 pm) and nighttime activity (mean activity counts per minute, 10 pm to 5:59 am). A daytime-to-nighttime activity ratio was calculated by dividing daytime activity by nighttime activity. The NIH Toolbox Dimensional Change Card Sort Test assessed cognitive flexibility (DCCST: fully corrected T score). Multivariate regression examined the association between the daytime-to-nighttime activity ratio and DCCST scores, adjusting for 2 covariates (age in years and NIH Toolbox Grip Strength fully corrected T score).

RESULTS

The mean daytime-to-nighttime activity ratio was 2.10 ± 1.17 (interquartile range, 1.42). Ratios for 6 participants (13.6%) were less than 1, revealing higher activity during nighttime hours rather than daytime hours. Higher daytime-to-nighttime ratios were associated with better DCCST scores (β = .364, P = .005).

CONCLUSIONS

The proportion of daytime activity versus nighttime activity was considerably low, indicating severe alterations in the rest/activity cycle. Higher daytime-to-nighttime activity ratios were associated with better executive function scores, suggesting that assessment of daytime activity could identify at-risk older ICU survivors during the early post-ICU transition period. Promotion of daytime activity and nighttime sleep may accelerate recovery and improve cognitive function.
