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.

Objectif : comprendre le point de vue des physiothérapeutes et des assistants-physiothérapeutes à l'égard de trois mesures de la fonction physique en soins intensifs : le questionnaire court sur la mesure de la mobilité des patients hospitalisés après des soins intensifs, l'échelle de mobilité la plus élevée de Johns Hopkins et le score de l'état fonctionnel en soins intensifs. Méthodologie : questionnaire en six questions distribué aux physiothérapeutes et assistants-physiothérapeutes travaillant dans une unité de soins intensifs pour adultes d'un hôpital universitaire américain. Les chercheurs ont formé un seul groupe de travail semi-structuré composé de sept physiothérapeutes recrutés par échantillonnage dirigé pour inclure des participants ayant diverses expériences cliniques. Résultats : sur le total de 22 participants potentiels, 18 physiothérapeutes et deux assistants-physiothérapeutes ont rempli le questionnaire. Sept physiothérapeutes ont participé au groupe de travail. Le questionnaire a fait état de points de vue favorables à l'égard de l'utilisation des trois mesures de la fonction physique en milieu clinique, et le groupe de travail a relevé cinq thèmes liés à leur utilisation : 1) facilité à établir le score, 2) utilité pour les communications interprofessionnelles, 3) facilité générale d'utilisation, 4) réactivité aux changements de la fonction physique et 5) généralisabilité entre les patients. Conclusion : la facilité à établir le score et l'utilité pour les communications interprofessionnelles étaient les thèmes les plus abordés pendant la présente étude, ce qui en souligne l'importance lors de la conception et du choix de mesures de la fonction physique en soins intensifs.

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.

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.

Psychology consultation patterns in a medical intensive care unit: A brief report.

PURPOSE/OBJECTIVE: Intensive care unit (ICU) survivors frequently experience long-lasting mental health, cognitive, and physiologic challenges. Psychologists have a role in providing interventions to reduce patient distress during critical illness and improve outcomes. There is limited data regarding psychology consultations in the ICU. This brief report characterizes psychology consultations in a medical intensive care unit (MICU) in an academic medical center. METHOD: Psychology consultations were prospectively tracked, with patient-related data retrospectively collected and analyzed. RESULTS: A total of 79 consecutive psychology consultations occurred at mean of 8 ± 6 days after MICU admission. Reasons for consultation were patient emotional distress (56%), rehabilitation therapy engagement (24%), family engagement (13%), cognitive disturbance (4%), and pain (4%). Patient characteristics were: mean age 56 ± 15 years, 54% women, 53% White, and 34% with psychiatric comorbidity at MICU admission. Patients referred for consultation had a longer MICU length of stay than the total MICU population (12 ± 9 days vs. 4 ± 6 days, p < .01). For consultations for emotional distress compared with limited rehabilitation therapy engagement, patient demographic characteristics were similar, with the exception of women (vs. men) being more commonly consulted for emotional distress (64 vs. 26%, p = .01). CONCLUSIONS: Patients with a longer MICU stay more commonly had a rehabilitation psychology consultation request, typically to provide support for emotional distress or engagement in rehabilitation therapy. Future research should evaluate the effectiveness of psychology interventions in the ICU. (PsycINFO Database Record (c) 2019 APA, all rights reserved).

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.

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.

Feasibility and Safety of Physical Therapy during Continuous Renal Replacement Therapy in the Intensive Care Unit.

RATIONALE: Early rehabilitation in an intensive care unit is associated with improved physical functioning and patient outcomes. However, relatively few data have been reported on physical therapy interventions during continuous renal replacement therapy (CRRT) for patients in intensive care units. OBJECTIVES: To evaluate the feasibility and safety of physical therapy interventions, delivered as part of routine clinical care, for patients undergoing CRRT in an intensive care unit. METHODS: Consecutive patients in the adult medical intensive care unit of one large tertiary care hospital who received physical therapy sessions while on CRRT were prospectively evaluated over 13 months. Physical therapy sessions were individualized on the basis of patients' physical impairments and activity tolerance, with patients' highest level of mobility recorded. Data on 15 different physiological abnormalities and potential safety events, including bleeding, dislodgement, or dysfunction of the CRRT catheter or circuit, were prospectively collected. MEASUREMENTS AND MAIN RESULTS: Eleven physical therapists delivered 268 rehabilitation sessions to 57 patients while they were receiving CRRT, with the following highest levels of mobility achieved during individual sessions: 78 (29%) bed exercises, 72 (27%) supine cycle ergometry, 80 (30%) sitting at edge of bed, 13 (5%) transfer to chair, and 25 (9%) standing or marching in place. No CRRT-specific safety events occurred (0%; 95% upper confidence interval, 6.3%). There were six non-CRRT-related potential safety events (2.2% of all physical therapy sessions; 95% confidence interval, 0.6-8.2%), all of which were transient changes in blood pressure. CONCLUSIONS: In this prospective observational study at one adult medical intensive care unit, we found that provision of bedside physical therapy while patients underwent CRRT is feasible, and appears safe.

Feasibility and safety of in-bed cycling for physical rehabilitation in the intensive care unit.

PURPOSE: The purpose was to evaluate the feasibility and safety of in-bed cycle ergometry as part of routine intensive care unit (ICU) physical therapist (PT) practice. MATERIALS AND METHODS: Between July 1, 2010, and December 31, 2011, we prospectively identified all patients admitted to a 16-bed medical ICU receiving cycling by a PT, prospectively collected data on 12 different potential safety events, and retrospectively conducted a chart review to obtain specific details of each cycling session. RESULTS: Six hundred eighty-eight patients received PT interventions, and 181 (26%) received a total of 541 cycling sessions (median [interquartile range {IQR}] cycling sessions per patient, 2 [1-4]). Patients' mean (SD) age was 57 (17) years, and 103 (57%) were male. The median (IQR) time from medical ICU admission to first PT intervention and first cycling session was 2 (1-4) and 4 (2-6) days, respectively, with a median (IQR) cycling session duration of 25 (18-30) minutes. On cycling days, the proportion of patients receiving mechanical ventilation, vasopressor infusions, and continuous renal replacement therapy was 80%, 8%, and 7%, respectively. A single safety event occurred, yielding a 0.2% event rate (95% upper confidence limit, 1.0%). CONCLUSIONS: Use of in-bed cycling as part of routine PT interventions in ICU patients is feasible and appears safe. Further study of the potential benefits of early in-bed cycling is needed.

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.

ICU early physical rehabilitation programs: financial modeling of cost savings.

OBJECTIVE: To evaluate the potential annual net cost savings of implementing an ICU early rehabilitation program. DESIGN: Using data from existing publications and actual experience with an early rehabilitation program in the Johns Hopkins Hospital Medical ICU, we developed a model of net financial savings/costs and presented results for ICUs with 200, 600, 900, and 2,000 annual admissions, accounting for both conservative- and best-case scenarios. Our example scenario provided a projected financial analysis of the Johns Hopkins Medical ICU early rehabilitation program, with 900 admissions per year, using actual reductions in length of stay achieved by this program. SETTING: U.S.-based adult ICUs. INTERVENTIONS: Financial modeling of the introduction of an ICU early rehabilitation program. MEASUREMENTS AND MAIN RESULTS: Net cost savings generated in our example scenario, with 900 annual admissions and actual length of stay reductions of 22% and 19% for the ICU and floor, respectively, were $817,836. Sensitivity analyses, which used conservative- and best-case scenarios for length of stay reductions and varied the per-day ICU and floor costs, across ICUs with 200-2,000 annual admissions, yielded financial projections ranging from -$87,611 (net cost) to $3,763,149 (net savings). Of the 24 scenarios included in these sensitivity analyses, 20 (83%) demonstrated net savings, with a relatively small net cost occurring in the remaining four scenarios, mostly when simultaneously combining the most conservative assumptions. CONCLUSIONS: A financial model, based on actual experience and published data, projects that investment in an ICU early rehabilitation program can generate net financial savings for U.S. hospitals. Even under the most conservative assumptions, the projected net cost of implementing such a program is modest relative to the substantial improvements in patient outcomes demonstrated by ICU early rehabilitation programs.
