Physiotherapists' and Physiotherapy Assistants' Perspectives on Using Three Physical Function Measures in the Intensive Care Unit: A Mixed-Methods Study

Purpose: We sought to understand physiotherapists' and physiotherapist assistants' perspectives on using three physical function measures in the intensive care unit (ICU) setting: the Activity Measure for Post-Acute Care Inpatient Mobility Short Form, the Johns Hopkins Highest Level of Mobility scale, and the Functional Status Score for the Intensive Care Unit. Method: A six-item questionnaire was developed and administered to physiotherapists and physiotherapist assistants working in adult ICUs at one U.S. teaching hospital. A single semi-structured focus group was conducted with seven physiotherapists, recruited using purposive sampling to include participants with a range of clinical experience. Results: Of 22 potential participants, 18 physiotherapists and 2 physiotherapist assistants completed the questionnaire. Seven physiotherapists participated in the focus group. The questionnaire found favourable perspectives on the use of the three physical function measures in clinical practice, and the focus group identified five themes related to clinicians' experience with using them: (1) ease of scoring, (2) usefulness in inter-professional communication, (3) general ease of use, (4) responsiveness to change in physical function, and (5) generalizability across patients. Conclusions: The most frequently discussed themes in this study were ease of scoring and usefulness in inter-professional communication, highlighting their importance in designing and selecting physical function measures for clinical use in the ICU setting.

Perceived barriers to early goal-directed mobility in the intensive care unit: Results of a quality improvement evaluation

BACKGROUND

A multicentre randomised trial demonstrated improved outcomes for intensive care unit (ICU) patients using early, goal-directed mobility implemented by nurses.

OBJECTIVES

The aim of the study was to evaluate barriers to nursing mobility, using a validated survey, during an ongoing quality improvement (QI) project (2019) in a medical ICU and determine changes from the pre-QI (2017) baseline.

METHODS

Nurses, nurse practitioners, physician assistants, and clinical technicians completed the 26-item Patient Mobilization Attitudes and Beliefs Survey for the ICU (PMABS-ICU). An overall score and three subscale scores (knowledge, attitudes, behaviour), each ranging from 0 to 100, were calculated; higher scores indicated greater barriers.

RESULTS

Seventy-five (93% response rate) nurses, eight (100%) nurse practitioners and physician assistants, and 11 (100%) clinical technicians completed the PMABS-ICU. For all respondents (N = 94), the mean (standard deviation) overall PMABS-ICU score was 32 (8) and the knowledge, attitudes and behaviour subscale scores were 22 (11), 33 (11), and 34 (8), respectively. Among all respondents completing the survey in both 2017 and 2019 (N = 46), there was improvement in the mean (95% confidence interval) overall score [-3.1 (-5.8, -0.5); p = .022] and in the knowledge [-5.1 (-8.9, -1.3); p = .010] and attitudes [-3.9 (-7.3, -0.6); p = .023] subscale scores. Among all respondents (N = 48) taking the PMABS-ICU for the first time in 2019 compared with those taking the survey before the QI project in 2017 (N = 99), there was improvement in the mean (95% confidence interval) overall score [-3.8 (-6.5, -1.1); p = .007] and in the knowledge [-6.9 (-11.0, -2.7); p = .001] and attitude [-4.3 (-8.1, -0.5); p = .027] subscale scores.

CONCLUSIONS

Using a validated survey administered to ICU nurses and other staff, before and during a structured QI project, there was a decrease in perceived barriers to mobility. Reduced barriers among those taking the survey for the first time during the QI project compared with those taking the survey before the QI project suggests a positive culture change supporting early, goal-directed mobility implemented by nurses.

Cognitive Stimulation in an Intensive Care Unit: A Qualitative Evaluation of Barriers to and Facilitators of Implementation

BACKGROUND

Delirium in the intensive care unit is associated with poor patient outcomes. Recent studies support nonpharmacological therapy, including cognitive stimulation, to address delirium. Understanding barriers to cognitive stimulation implemented by nurses during clinical care is essential to translating evidence into practice.

OBJECTIVE

To use qualitative methods through a structured quality improvement project to understand nurses' perceived barriers to implementing a cognitive stimulation intervention in a medical intensive care unit.

METHODS

Data were collected through semistructured interviews with nurses in a medical intensive care unit. Data were categorized into themes by using thematic analysis and the Consolidated Framework for Implementation Research. During cognitive stimulation, nurses reviewed with patients a workbook of evidence-based tasks (focused on math, alertness, motor skills, visual perception, memory, problem-solving, and language).

RESULTS

The 23 nurses identified 62 barriers to and 26 facilitators of cognitive stimulation. These data were summarized into 12 barrier and 9 facilitator themes corresponding to the following Consolidated Framework for Implementation Research domains: Intervention Characteristics, Outer Setting, Inner Setting, and Characteristics of Individuals. Nurses also identified several facilitators within the Process domain. Patient-specific variables, including sedation, were the most frequently reported barriers. Other barriers included cognitive stimulation not being prioritized, nursing staff-related issues, documentation burden, and a lack of understanding of, or appreciation for, the evidence supporting cognitive stimulation.

CONCLUSIONS

Implementation of cognitive stimulation requires a multidisciplinary approach to address perceived barriers arising from the organization, context, and individuals associated with the intervention, as well as the intervention itself.

Identifying Barriers to Nurse-Facilitated Patient Mobility in the Intensive Care Unit

BACKGROUND

Nurse-facilitated mobility of patients in the intensive care unit can improve outcomes. However, a gap exists between research findings and their implementation as part of routine clinical practice. Such a gap is often attributed, in part, to the barrier of lack of time. The Translating Evidence Into Practice model provides a framework for research implementation, including recommendations for identifying barriers to implementation via direct observation of clinical care.

OBJECTIVES

To report on design, implementation, and outcomes of an approach to identify and understand lack of time as a barrier to nurse-facilitated mobility in the intensive care unit.

METHODS

An interprofessional team designed the observational process and evaluated the resulting data by using qualitative content analysis.

RESULTS

During three 4-hour observations of 2 nurses and 1 nursing technician, 194 distinct tasks were performed (ie, events). A total of 4 categories of nurses' work were identified: patient care (47% of observation time), provider communication (25%), documentation (18%), and down time (10%). In addition, 3 types of potential mobility events were identified: in bed, edge of bed, and out of bed. The 194 observed events included 34 instances (18%) of potential mobility events that could be implemented: in bed (53%), edge of bed (6%), and out of bed (41%).

CONCLUSIONS

Nurses have limited time for additional clinical activities but may miss potentially important opportunities for facilitating patient mobility during existing patient care. The proposed method is feasible and helpful in empirically investigating barriers to nurse-facilitated patient mobility in the intensive care unit.

Perceived Barriers to Mobility in a Medical ICU: The Patient Mobilization Attitudes & Beliefs Survey for the ICU

PURPOSE

Early mobilization in the intensive care unit (ICU) can improve patient outcomes but has perceived barriers to implementation. As part of an ongoing structured quality improvement project to increase mobilization of medical ICU patients by nurses and clinical technicians, we adapted the existing, validated Patient Mobilization Attitudes & Beliefs Survey (PMABS) for the ICU setting and evaluated its performance characteristics and results.

MATERIALS AND METHODS

The 26-item PMABS adapted for the ICU (PMABS-ICU) was administered as an online survey to 163 nurses, clinical technicians, respiratory therapists, attending and fellow physicians, nurse practitioners, and physician assistants in one medical ICU. We evaluated the overall and subscale (knowledge, attitude, and behavior) scores and compared these scores by respondent characteristics (clinical role and years of work experience).

RESULTS

The survey response rate was 96% (155/163). The survey demonstrated acceptable discriminant validity and acceptable internal consistency for the overall scale (Cronbach α: 0.82, 95% confidence interval: 0.76-0.85), with weaker internal consistency for all subscales (Cronbach α: 0.62-0.69). Across all respondent groups, the overall barrier score (range: 1-100) was relatively low, with attending physicians perceiving the lowest barriers (median [interquartile range]: 30 [28-34]) and nurses perceiving the highest (37 [31-40]). Within the first 10 years of work experience, greater experience was associated with a lower overall barrier score (-0.8 for each additional year; P = 0.02).

CONCLUSIONS

In our medical ICU, across 6 different clinical roles, there were relatively low perceived barriers to patient mobility, with greater work experience over the first 10 years being associated with lower perceived barriers. As part of a structured quality improvement project, the PMABS-ICU may be valuable in assisting to identify specific perceived barriers for consideration in designing mobility interventions for the ICU setting.

Safety and Feasibility of a Protocolized Approach to In-Bed Cycling Exercise in the Intensive Care Unit: Quality Improvement Project

BACKGROUND

In-bed, supine cycle ergometry as a part of early rehabilitation in the intensive care unit (ICU) appears to be safe, feasible, and beneficial, but no standardized protocol exists. A standardized protocol may help guide use of cycle ergometry in the ICU.

OBJECTIVE

This study investigated whether a standardized protocol for in-bed cycling is safe and feasible, results in cycling for a longer duration, and achieves a higher resistance.

DESIGN

A quality improvement (QI) project was conducted.

METHODS

A 35-minute in-bed cycling protocol was implemented in a single medical intensive care unit (MICU) over a 7-month quality improvement (QI) period compared to pre-existing, prospectively collected data from an 18-month pre-QI period.

RESULTS

One hundred and six MICU patients received 260 cycling sessions in the QI period vs. 178 MICU patients receiving 498 sessions in the pre-QI period. The protocol was used in 249 (96%) of cycling sessions. The QI group cycled for longer median (IQR) duration (35 [25-35] vs. 25 [18-30] minutes, P < .001) and more frequently achieved a resistance level greater than gear 0 (47% vs. 17% of sessions, P < .001). There were 4 (1.5%) transient physiologic abnormalities during the QI period, and 1 (0.2%) during the pre-QI period ( P = .031).

LIMITATIONS

Patient outcomes were not evaluated to understand if the protocol has clinical benefits.

CONCLUSIONS

Use of a protocolized approach for in-bed cycling appears safe and feasible, results in cycling for longer duration, and achieved higher resistance.

Safety and feasibility of femoral catheters during physical rehabilitation in the intensive care unit

OBJECTIVE

Femoral catheters pose a potential barrier to early rehabilitation in the intensive care unit (ICU) due to concerns, such as catheter removal, local trauma, bleeding, and infection. We prospectively evaluated the feasibility and safety of physical therapy (PT) in ICU patients with femoral catheters.

DESIGN, SETTING, AND PATIENTS

We evaluated consecutive medical ICU patients who received PT with a femoral venous, arterial, or hemodialysis catheter(s) in situ.

MEASUREMENTS AND MAIN RESULTS

Of 1074 consecutive patients, 239 (22%) received a femoral catheter (81% venous, 29% arterial, 6% hemodialysis; some patients had >1 catheter). Of those, 101 (42%) received PT interventions, while the catheter was in situ, for a total of 253 sessions over 210 medical ICU (MICU) days. On these 210 MICU days, the highest daily activity level achieved was 49 (23%) standing or walking, 57 (27%) sitting, 25 (12%) supine cycle ergometry, and 79 (38%) in-bed exercises. During 253 PT sessions, there were no catheter-related adverse events giving a 0% event rate (95% upper confidence limit of 2.1% for venous catheters).

CONCLUSIONS

Physical therapy interventions in MICU patients with in situ femoral catheters appear to be feasible and safe. The presence of a femoral catheter should not automatically restrict ICU patients to bed rest.
