Nurses' Perceptions of Barriers to Out-of-Bed Activities Among Patients Receiving Mechanical Ventilation

Impact of knowledge, attitudes and self-reported practices of nurses on early mobilization of mechanically ventilated patients in the ICU

BACKGROUND

Many ICUs worldwide are striving to integrate early mobilization as part of critical care rehabilitation. However, ICU nurses, who are essential contributors to the early mobilization of critically ill patients, still lack comprehensive surveys assessing their knowledge, beliefs, and practices regarding the early mobilization of mechanically ventilated patients.

AIM

To analyse the knowledge, attitudes, and practices of intensive care unit (ICU) nurses regarding the early mobilization of mechanically ventilated patients and to explore the effects of these practices.

STUDY DESIGN

A multicentre cross-sectional study. ICU nurses in five tertiary hospitals in Zhejiang Province, China, were selected by convenience sampling and invited to complete an online questionnaire between 1 June 2021 and 15 June 2021. Sociodemographic data and the knowledge, attitudes, and practices of ICU nurses regarding early mobilization.

RESULTS

A total of 296 valid questionnaires were collected, for a response rate of approximately 77.5%. The average scores for knowledge, attitudes, and practices of ICU nurses regarding the early mobilization of mechanically ventilated patients were 42.7 ± 7.4, 34.3 ± 6.5, and 47.1 ± 6.5, respectively, which were good scores. Quantile regressions showed that at the 25% and 50% quartiles, increases in knowledge and attitude scores resulted in increases in practice scores (p < .001); however, at the 75% quartile, increases in knowledge scores did not result in practice score increases (t = 0.000, p = .999); moreover, there was still a 0.5-point increase in practice scores per 1-point increase in attitude scores (t = 0.500, p < .001).

CONCLUSIONS

The knowledge, attitudes, and self-reported practices of ICU nurses were good, although there is room for improvement. Considering that the influence of attitudes on practice improvement is more important than knowledge, ICU managers should promote knowledge transformation, strengthen attitudes, and adopt comprehensive measures to promote the early mobilization of mechanically ventilated patients in the ICU.

RELEVANCE TO CLINICAL PRACTICE

To optimize the early mobilization of mechanically ventilated patients in the ICU, introducing multipronged support strategies based on the knowledge and attitudes of ICU nurses is recommended to promote the implementation of such practices.

Treatment Fidelity in 94 Randomized Controlled Trials of Physical Rehabilitation in the ICU: A Scoping Review

OBJECTIVES

Recent reviews demonstrated discordant effects of ICU-based physical rehabilitation on physical function. These inconsistencies may be related to differences in treatment fidelity-the extent to which a protocol is delivered as planned. Before evaluating the association of fidelity with outcomes, we must first understand the extent of treatment fidelity reporting in ICU-based physical rehabilitation randomized controlled trials (RCTs).

DATA SOURCES

Six electronic databases from inception to December 2022.

STUDY SELECTION

We included RCTs enrolling adults or children admitted to the ICU, if greater than or equal to 50% were invasively mechanically ventilated greater than 24 hours, and underwent an ICU-based physical rehabilitation intervention, with no limitation to comparators or outcomes.

DATA EXTRACTION

We screened and extracted data independently and in duplicate, with a third reviewer as needed. Extracted data included study characteristics, treatment descriptions, and the presence of National Institutes of Health Behaviour Change Consortium (NIH-BCC) treatment fidelity tool components. Treatment fidelity scores were calculated as the proportion of reported (numerator) out of total NIH-BCC components (denominator). We calculated scores across studies and by treatment group (intervention vs. comparator). We used linear regression to assess for a time trend in study treatment fidelity scores.

DATA SYNTHESIS

Of 20,433 citations, 94 studies met inclusion criteria. Authors reported a median (first-third quartiles) of 19% (14-26%) of treatment fidelity components across studies. Intervention group scores were higher than comparator groups (24% [19-33%] vs. 14% [5-24%], p < 0.01). We found a mean increase in study treatment fidelity scores by 0.7% (0.3 points) per year.

CONCLUSIONS

Only 19% of treatment fidelity components were reported across studies, with comparator groups more poorly reported. Future research could investigate ways to optimize treatment fidelity reporting and determine characteristics associated with treatment fidelity conduct in ICU-based physical rehabilitation RCTs.

Perceived Barriers to Patient Mobilization Among Therapy and Nursing Acute Care Staff: A Multi-Site Survey Study

OBJECTIVE

To identify differences in perceived barriers to patient mobilization in acute care among therapy and nursing clinicians, and among hospitals of different sizes and types.

DESIGN

Cross-sectional survey study.

SETTING

Eight hospitals of various sizes and types (teaching vs non-teaching; urban vs rural), from 2 different states in the Western region of the United States.

PARTICIPANTS

A nonprobability sample of 568 acute care clinicians (N=586) involved in direct patient care were surveyed. Clinicians indicated a clinical role within the branch of therapy (physical therapy or occupational therapy) or nursing (registered nurse or nurse assistant).

MAIN OUTCOME MEASURES

The Patient Mobilization Attitudes and Beliefs Survey (PMABS) was used to assess perceived barriers to early patient mobilization among therapy and nursing staff. A PMABS total score and 3 subscale scores (knowledge, attitudes, or behaviors associated with barriers to mobilization) were calculated, with higher scores indicative of greater mobilization barriers.

RESULTS

Mean PMABS total scores were significantly lower (better) for therapy providers (24.63±6.67) than nursing providers (38.12±10.95), P<.001. Additionally, therapy providers had significantly lower scores than nursing providers on all 3 subscales (all P<.001). Item-specific analyses revealed significant differences in responses between therapy and nursing staff on 22 of 25 items, with nursing staff indicating greater perceptions of barriers than therapy staff on 20 of the 22 items. The top 5 items with the largest response differences between therapy and nursing clinicians included adequate time to mobilize patients, understanding appropriate referral to therapy staff, knowledge on when it is safe to mobilize patients, confidence in the ability to mobilize patients, and receiving training on methods of safe mobilization. While hospital type did not affect perceived barriers to early mobilization, PMABS scores were significantly higher for large and small hospitals when compared to medium-sized hospitals.

CONCLUSION

Perceived barriers to patient mobilization exist among therapy and nursing acute care clinicians, with greater barriers noted among nursing staff for knowledge, attitudes, and behaviors associated with patient mobility practices. Findings suggest future work is warranted, with opportunities for therapy providers to collaborate with nursing providers to address barriers to implementing patient mobility.

Factors Associated With Physical Activity in Hospitalized Patients With Dementia

Older adults continue to spend little time engaged in physical activity when hospitalized. The purpose of this study was to (a) describe activity among hospitalized older adults with dementia and (b) identify the association between specific factors (gender, ambulation independence, comorbidities, race, and hospital setting) and their physical activity. This descriptive study utilized baseline data on the first 79 participants from the Function Focused Care for Acute Care using the Evidence Integration Triangle. Multiple linear regression models were run using accelerometry data from the first full day of hospitalization. The participants spent an average of 83.7% of their time being sedentary. Male gender, ambulation independence, and hospital setting (the hospital in which the patient was admitted) were associated with greater activity. This study reports on the limited time spent in activity for older adults with dementia when hospitalized and highlights patient profiles that are particularly vulnerable to sedentary behavior in the hospital setting.
