American Association of Nurse Practitioners Research Agenda, 2023-2028.

ABSTRACT: This report highlights the 2023-2028 American Association of Nurse Practitioners Research Agenda (AANP-RA), which focuses on the research goals of AANP as an organization and is based on its mission and strategic plan. The purpose of the AANP Research Agenda is to outline research priorities that advance the AANP Strategic Plan and concurrently address gaps in nursing science. American Association of Nurse Practitioners supports research studies that are rigorously designed and conducted using quantitative, qualitative, and mixed-methods approaches, as well as implementation science with the potential to positively impact both NP practice and patient health outcomes. The AANP-RA strategy is guided by the PEARL acronym: examining NP Practice, Education, policy Advocacy, Research, and Leadership. A discussion of each area is presented along with suggested topics.

Use of deep artificial neural networks to identify stroke during triage via subtle changes in circulating cell counts.

BACKGROUND: The development of tools that could help emergency department clinicians recognize stroke during triage could reduce treatment delays and improve patient outcomes. Growing evidence suggests that stroke is associated with several changes in circulating cell counts. The aim of this study was to determine whether machine-learning can be used to identify stroke in the emergency department using data available from a routine complete blood count with differential. METHODS: Red blood cell, platelet, neutrophil, lymphocyte, monocyte, eosinophil, and basophil counts were assessed in admission blood samples collected from 160 stroke patients and 116 stroke mimics recruited from three geographically distinct clinical sites, and an ensemble artificial neural network model was developed and tested for its ability to discriminate between groups. RESULTS: Several modest but statistically significant differences were observed in cell counts between stroke patients and stroke mimics. The counts of no single cell population alone were adequate to discriminate between groups with high levels of accuracy; however, combined classification using the neural network model resulted in a dramatic and statistically significant improvement in diagnostic performance according to receiver-operating characteristic analysis. Furthermore, the neural network model displayed superior performance as a triage decision making tool compared to symptom-based tools such as the Cincinnati Prehospital Stroke Scale (CPSS) and the National Institutes of Health Stroke Scale (NIHSS) when assessed using decision curve analysis. CONCLUSIONS: Our results suggest that algorithmic analysis of commonly collected hematology data using machine-learning could potentially be used to help emergency department clinicians make better-informed triage decisions in situations where advanced imaging techniques or neurological expertise are not immediately available, or even to electronically flag patients in which stroke should be considered as a diagnosis as part of an automated stroke alert system.

Patient reported symptom outcomes during medication titration for adult heart failure management.

AIMS AND OBJECTIVES: This project used the Patient Reported Outcomes Measurement Information System (PROMIS) tools to evaluate heart failure patient's experiences of dyspnea, fatigue, and physical mobility during initiation and up titration of drugs in an outpatient setting. BACKGROUND: Investigating patient reported outcome may improve adherence to GDMT. Theoretical support for this study is found in the University of California, Theory of Symptom Management. DESIGN: Exploratory, repeated measures design. METHODS: Patients (n = 21) completed three PROMIS questionnaires for dyspnea, fatigue and physical mobility when GDMT was started or up titrated, and again at a follow up appointment within 30 days (+/- 14 days) of the baseline measures. Patients were asked open- ended queries regarding the usefulness of these questionnaires in identifying and managing symptoms. Provider input was sought on usefulness of the tools in clinical practice and decision making. RESULTS: Dyspnea change scores significantly decreased (p = .001), physical mobility scores significantly increased (p = .017), and fatigue scores did not change (p = .319). Duration of HF diagnosis was associated with dyspnea change scores. Patients reported PROMIS tools were easy to use, while providers felt the tools were easy for patients to use but were too long and time intensive for usual office practice. CONCLUSIONS: Dyspnea and physical mobility improved with up titration of GDMT but fatigue did not change. RELEVANCE TO CLINICAL PRACTICE: PROMIS tools could be helpful in tracking selected symptom changes during GDMT HF medication initiation or up titration for HF management if reformulated into shorter format.

Bioinformatic analysis of brain-specific miRNAs for identification of candidate traumatic brain injury blood biomarkers.

BACKGROUND: Detection of brain-specific miRNAs in the peripheral blood could serve as a surrogate marker of traumatic brain injury (TBI). Here, we systematically identified brain-enriched miRNAs, and tested their utility as TBI biomarkers in the acute phase of care. METHODS: Publically available microarray data generated from 29 postmortem human tissues were used to rank 1,364 miRNAs in terms of their degree of brain-specific expression. Levels of the top six ranked miRNAs were then prospectively measured in serum samples collected from 10 Patients with TBI at hospital admission, as well as from 10 controls. RESULTS: The top six miRNAs identified in our analysis (miR-124-3p, miR-219a-5p, miR-9-5p, miR-9-3p, miR-137, and miR-128-3p) were enriched 70 to 320-fold in brain relative to other tissues, and exhibited dramatically greater brain specificity compared to several miRNAs previously proposed as biomarkers. Furthermore, their levels were elevated in serum from patients with TBI compared to controls, and could collectively discriminate between groups with 90% sensitivity and 100% specificity. Interestingly, subsequent informatic pathway analysis revealed that their target transcripts were enriched for components of signaling pathways active in peripheral organs involved in common post-TBI complications. CONCLUSIONS: The six candidate miRNAs identified in this preliminary study have promise as blood biomarkers of TBI, and could also be molecular contributors to systemic physiologic changes commonly observed post-injury.

One Team's Experience with Integrating Flexible Visitation in the Medical Intensive Care Unit.

Integration of flexible visitation into a large health system requires concentrated effort. Evaluating impact on patient, family, and staff outcomes is important to facilitate changes and ensure visiting policy success. The medical intensive care unit staff participated in a collaborative quality improvement effort to encourage flexible visitation. The integration of flexible visitation spanned an 18-month period, timed to accompany a transition to a new setting with rooms designed to support visitor presence. This article details these efforts, outcomes, and important gaps for future work evaluating integration of flexible visitation in critical care.

Procedural Pain in the Adult Neurological Intensive Care Unit: A Retrospective Study Examining Arterial Line Insertion.

BACKGROUND: This was a retrospective chart review of procedural pain assessments and interventions during arterial catheter insertion in an adult neurological intensive care unit where patients with impaired consciousness are common. Overall, pain assessment was well documented (100%) by Registered Nurses, but not specific to arterial line insertion. Nurse practitioners commonly placed arterial lines and used local analgesia in over 75% of the documented procedures. AIMS: The purpose of this study was to examine healthcare providers' pain-related practices documented during arterial catheter insertion, one of the most painful procedures in a neurological intensive care unit. Secondary purposes were determining whether patient characteristics, procedure-related factors, or provider licensure were associated with pain assessment or procedural pain interventions. DESIGN: A retrospective records review design was used. METHODS: 120 electronic patient medical records were reviewed during a one-year period. RESULTS: 100 charts met inclusion criteria. Nurses assessed all pain within 4 hours following the procedure in all charts but procedure-specific pain assessments were documented in 4% of charts. Pain-related interventions for arterial line insertion were local analgesic (76% of charts) and other procedure-specific interventions (10%). Significant associations occurred between procedure specific pain assessments and decreased number of insertion attempts (p = .006) and between pain interventions and number of insertion attempts (p = .003). No provider documented procedural pain assessment regarding arterial line insertion. Associations between patient characteristics and pain interventions were significant for patient ethnicity (F = 8.967, p = .007). CONCLUSIONS: Overall pain assessment was documented (100%) but not specific to arterial line insertion. Although arterial line insertion can be extremely painful, patients were rarely assessed for such pain by any clinician; 14% did not receive any preprocedural analgesia. CLINICAL IMPLICATIONS: The lack of procedural pain assessment in this vulnerable population indicates a need for increased pain management education for clinicians and further investigations to determine whether sufficient analgesia is provided to reduce procedural pain during arterial line insertion.

Early Therapeutic Mobility and Changes in Scores for Pain and Fatigue.

This report is a secondary analysis of data from a larger study of a nurse-led early therapeutic mobility intervention among patients receiving mechanical ventilation. This analysis evaluated whether intervention frequency or intensity was associated with pain or fatigue. Frequency was defined as once-daily versus twice-daily interventions. Intensity was defined as low (in-bed activities) or moderate (out-of-bed activities). Thirty-nine patients self-reported pain and fatigue immediately before and after the intervention. Neither pain nor fatigue increased significantly (mean increase, <1 [scale of 0-10] for 95% of interventions). Four patients reported decrements in pain; 1 reported a decrease in fatigue. Less than 5% of enrolled patients indicated a score change of +4 to +6 for pain or fatigue, typically with the first intervention that included sitting at the edge of the bed. Future research could examine the distress associated with these symptoms in critically ill adults receiving early therapeutic mobility interventions.

Validity and Reliability of the Transport Triage Tool.

BACKGROUND: Standards for interfacility transport in the United States recommend that each transport request be triaged to ensure that each patient is transported by an appropriate mechanism and by the appropriate clinicians in order to meet the patient's intratransport needs. No instrument currently exists to meet that need. The Transport Triage Tool, a novel instrument, has been designed to determine the clinician (paramedic, registered nurse, or advanced practice registered nurse) who will best meet the patient's needs during transport. OBJECTIVE: To assess psychometric elements-that is, validity and reliability-of the Transport Triage Tool when used by health care professionals in determining which clinician is appropriate for interfacility transport. METHODS: A 3-step process was used to initially evaluate the reliability and validity of this tool when assigning a lead clinician during transport. Content and predictive validity were evaluated. Both intrarater and interrater agreement were used to examine reliability. RESULTS: Predictive validity was supported by an area under the receiver operating characteristic curve of 0.847 and a Youden index of 0.31. Percentage agreement and Cohen κ were reasonable across all periods of testing. CONCLUSIONS: The Transport Triage Tool has acceptable predictive validity and reliability; however, this preliminary evaluation indicates that further refinement is needed. Large tertiary centers that offer variations in transport team composition may be able to use the Tool in its present form to train and evaluate individuals who make decisions regarding interfacility transport, although additional testing and evaluation are recommended.

Clinical Practice Guidelines for the Prevention and Management of Pain, Agitation/Sedation, Delirium, Immobility, and Sleep Disruption in Adult Patients in the ICU.

OBJECTIVE: To update and expand the 2013 Clinical Practice Guidelines for the Management of Pain, Agitation, and Delirium in Adult Patients in the ICU. DESIGN: Thirty-two international experts, four methodologists, and four critical illness survivors met virtually at least monthly. All section groups gathered face-to-face at annual Society of Critical Care Medicine congresses; virtual connections included those unable to attend. A formal conflict of interest policy was developed a priori and enforced throughout the process. Teleconferences and electronic discussions among subgroups and whole panel were part of the guidelines' development. A general content review was completed face-to-face by all panel members in January 2017. METHODS: Content experts, methodologists, and ICU survivors were represented in each of the five sections of the guidelines: Pain, Agitation/sedation, Delirium, Immobility (mobilization/rehabilitation), and Sleep (disruption). Each section created Population, Intervention, Comparison, and Outcome, and nonactionable, descriptive questions based on perceived clinical relevance. The guideline group then voted their ranking, and patients prioritized their importance. For each Population, Intervention, Comparison, and Outcome question, sections searched the best available evidence, determined its quality, and formulated recommendations as "strong," "conditional," or "good" practice statements based on Grading of Recommendations Assessment, Development and Evaluation principles. In addition, evidence gaps and clinical caveats were explicitly identified. RESULTS: The Pain, Agitation/Sedation, Delirium, Immobility (mobilization/rehabilitation), and Sleep (disruption) panel issued 37 recommendations (three strong and 34 conditional), two good practice statements, and 32 ungraded, nonactionable statements. Three questions from the patient-centered prioritized question list remained without recommendation. CONCLUSIONS: We found substantial agreement among a large, interdisciplinary cohort of international experts regarding evidence supporting recommendations, and the remaining literature gaps in the assessment, prevention, and treatment of Pain, Agitation/sedation, Delirium, Immobility (mobilization/rehabilitation), and Sleep (disruption) in critically ill adults. Highlighting this evidence and the research needs will improve Pain, Agitation/sedation, Delirium, Immobility (mobilization/rehabilitation), and Sleep (disruption) management and provide the foundation for improved outcomes and science in this vulnerable population.

Patient Safety Events during Critical Care Transport.

OBJECTIVE: Patient safety events (PSEs) occurring during interfacility transport have not been studied comprehensively in critical care transport (CCT) teams in the United States. The purpose of this research was to investigate the type and frequency of PSEs during CCT between hospitals; to explore the impact of patient stability, vulnerability, complexity, predictability, and resiliency; and to examine if the nurse factors of licensure or experience and transport factors of duration or mode of transport influence the frequency of PSEs. The study was conducted at a large hospital-based quaternary health care system in the Midwestern United States. METHODS: This was a retrospective, descriptive correlational study using chart review. The study selected 50 sequential qualifying cases with PSEs and randomly selected control cases reviewed at a single site over a 5-month period. RESULTS: The rate of PSEs was 27.7 events per 1,000 patient contacts. Of 9 reported adverse event types, new or recurrent hypoxia had the greatest frequency. Hypoxia, when present at the time of initial CCT contact, was associated with the PSE occurrence (P = .046). Duration of transport was a significant predictor of PSEs (P = .025). CONCLUSION: Pretransport hypoxia and duration of transport are independent predictors for intratransport PSEs, particularly intratransport hypoxia.

Dose of Early Therapeutic Mobility: Does Frequency or Intensity Matter?

OBJECTIVE: Investigate the feasibility of a nurse-led mobility protocol and compare the effects of once- versus twice-daily episodes of early therapeutic mobility (ETM) and low- versus moderate-intensity ETM on serum biomarkers of inflammation and selected outcomes in critically ill adults. DESIGN: Randomized interventional study with repeated measures and blinded assessment of outcomes. SETTING: Four adult intensive care units (ICUs) in two academic medical centers. SUBJECTS: Fifty-four patients with > 48 hr of mechanical ventilation (MV). INTERVENTION: Patients were assigned to once- or twice-daily ETM via sealed envelope randomization at enrollment. Intensity of (in-bed vs. out-of-bed) ETM was administered according to protocolized patient assessment. MEASUREMENTS: Interleukins 6, 10, 8, 15, and tumor necrosis factor-α were collected from serum before and after ETM; change scores were used in the analyses. Manual muscle and handgrip strength, delirium onset, duration of MV, and ICU length of stay (LOS) were evaluated as patient outcomes. MAIN RESULTS: Hypotheses regarding the inflammatory biomarkers were not supported based on confidence intervals. Twice-daily intervention was associated with reduced ICU LOS. Moderate-intensity (out-of-bed) ETM was associated with greater manual muscle test scores and handgrip strength and reduced occurrence of delirium. CONCLUSION: Findings from this study suggest that nurses can provide twice-daily mobility interventions that include sitting on the edge of the bed once patients have a stable status without altering a pro-inflammatory serum biomarker profile.

Attitudes Toward Communication and Collaboration After Participation in a Mock Page Program: A Pilot of an Interprofessional Approach to Surgical Residency Preparation.

OBJECTIVE: A source of insecurity among new physicians and new nurses is communicating and managing acute changes in patient condition. Mock page programs are an effective method for teaching communication and clinical decision-making skills to medical students. Joint participation in a mock page program provides a unique opportunity for medical and nursing students to practice communication, collaboration, and clinical decision-making in a low-risk learning environment. The purpose of this pilot study was to examine attitudes toward communication and collaboration among medical and nursing students after participation in a mock page program. DESIGN: Twenty-four medical students participating in a surgical residency preparatory course were paired with 24 senior level nursing students. Over a period of 3 weeks, nursing students delivered 5 mock pages to the medical students. Mock pages consisted of peer-reviewed, prescripted scenarios depicting patients experiencing common postoperative complications. A 12-question survey measuring attitudes toward communication and collaboration between physicians and nurses was administered prior to delivery of the first page and after delivery of the last page. A dependent sample t test was used to perform item analysis. RESULTS: Individual item analysis of medical student surveys indicated significant improvement in attitudes toward communication and collaboration with nurses in 12 out of 12 survey items (p < 0.05). Individual item analysis of nursing student surveys indicated significant improvement in attitudes toward communication and collaboration with physicians in 6 out of 10 survey items (p < 0.05). There was no decline in attitudes among any of the survey items. CONCLUSIONS: The results from this study suggest that an interprofessional mock page program improves attitudes toward communication and collaboration between medical and nursing students. This program has the potential to improve the quality of education and increase confidence among medical and nursing students as they prepare for their professional roles.

Comfort and Fluid Retention in Adult Patients Receiving Hemodialysis.

Successful hemodialysis treatments for patients with renal failure depend on patient adherence to prescribed treatment regimens. Lack of adherence may contribute to patient discomfort between hemodialysis treatments. This article reports a descriptive, correlational feasibility study that utilized Kolcaba's Comfort Theory as a framework. The purpose of the study was to determine a potential relationship between comfort and fluid retention (a proxy for adherence) in adults with end stage renal disease receiving hemodialysis. A convenience sample of 51 patients receiving hemodialysis was studied. Comparisons of patient weight gain between hemodialysis treatment sessions measured fluid retention by proxy. Results indicated no significant relationship between the variables of comfort and adherence to fluid restrictions. However, this finding has potential to support clinical practice to minimize weight gain to sustain comfort. Awareness of comfort as a consideration for adherence to prescribed treatment regimens may help nurses coach individuals to improve treatment adherence.

The nurse response to abnormal vital sign recording in the emergency department.

AIMS AND OBJECTIVES: To examine what occurs after a recorded observation of at least one abnormal vital sign in the emergency department. The aims were to determine how often abnormal vital signs were recorded, what interventions were documented, and what factors were associated with documented follow-up for abnormal vital signs. BACKGROUND: Monitoring quality of care, and preventing or intervening before harm occurs to patients are central to nurses' roles. Abnormal vital signs have been associated with poor patient outcomes and require follow-up after the observation of abnormal readings to prevent patient harm related to a deteriorating status. This documentation is important to quality and safety of care. DESIGN: Observational, retrospective chart review. METHODS: Modified Early Warning Score was calculated for all recorded vital signs for 195 charts. Comparisons were made between groups: (1) no abnormal vital signs, (2) abnormal vital sign present, but normal Modified Early Warning Score and (3) critically abnormal Modified Early Warning Score. RESULTS: About 62·1% of charts had an abnormal vital sign documented. Critically abnormal values were present in 14·9%. No documentation was present in 44·6% of abnormal cases. When interventions were documented, it was usually to notify the physician. The timing within the emergency department visit when the abnormalities were observed and the degree of abnormality had significant relationships to the presence of documentation. CONCLUSIONS: It is doubtful that nurses do not recognise abnormalities because more severely abnormal vital signs were more likely to have documented follow-up. Perhaps the interruptive nature of the emergency department or the prioritised actions of the nurse impacted documentation within this study. Further research is required to determine why follow-up is not being documented. RELEVANCE TO CLINICAL PRACTICE: To ensure safety and quality of patient care, accurate documentation of responses to abnormal vital signs is required.

Standardized Rehabilitation and Hospital Length of Stay Among Patients With Acute Respiratory Failure: A Randomized Clinical Trial.

IMPORTANCE: Physical rehabilitation in the intensive care unit (ICU) may improve the outcomes of patients with acute respiratory failure. OBJECTIVE: To compare standardized rehabilitation therapy (SRT) to usual ICU care in acute respiratory failure. DESIGN, SETTING, AND PARTICIPANTS: Single-center, randomized clinical trial at Wake Forest Baptist Medical Center, North Carolina. Adult patients (mean age, 58 years; women, 55%) admitted to the ICU with acute respiratory failure requiring mechanical ventilation were randomized to SRT (n=150) or usual care (n=150) from October 2009 through May 2014 with 6-month follow-up. INTERVENTIONS: Patients in the SRT group received daily therapy until hospital discharge, consisting of passive range of motion, physical therapy, and progressive resistance exercise. The usual care group received weekday physical therapy when ordered by the clinical team. For the SRT group, the median (interquartile range [IQR]) days of delivery of therapy were 8.0 (5.0-14.0) for passive range of motion, 5.0 (3.0-8.0) for physical therapy, and 3.0 (1.0-5.0) for progressive resistance exercise. The median days of delivery of physical therapy for the usual care group was 1.0 (IQR, 0.0-8.0). MAIN OUTCOMES AND MEASURES: Both groups underwent assessor-blinded testing at ICU and hospital discharge and at 2, 4, and 6 months. The primary outcome was hospital length of stay (LOS). Secondary outcomes were ventilator days, ICU days, Short Physical Performance Battery (SPPB) score, 36-item Short-Form Health Surveys (SF-36) for physical and mental health and physical function scale score, Functional Performance Inventory (FPI) score, Mini-Mental State Examination (MMSE) score, and handgrip and handheld dynamometer strength. RESULTS: Among 300 randomized patients, the median hospital LOS was 10 days (IQR, 6 to 17) for the SRT group and 10 days (IQR, 7 to 16) for the usual care group (median difference, 0 [95% CI, -1.5 to 3], P = .41). There was no difference in duration of ventilation or ICU care. There was no effect at 6 months for handgrip (difference, 2.0 kg [95% CI, -1.3 to 5.4], P = .23) and handheld dynamometer strength (difference, 0.4 lb [95% CI, -2.9 to 3.7], P = .82), SF-36 physical health score (difference, 3.4 [95% CI, -0.02 to 7.0], P = .05), SF-36 mental health score (difference, 2.4 [95% CI, -1.2 to 6.0], P = .19), or MMSE score (difference, 0.6 [95% CI, -0.2 to 1.4], P = .17). There were higher scores at 6 months in the SRT group for the SPPB score (difference, 1.1 [95% CI, 0.04 to 2.1, P = .04), SF-36 physical function scale score (difference, 12.2 [95% CI, 3.8 to 20.7], P = .001), and the FPI score (difference, 0.2 [95% CI, 0.04 to 0.4], P = .02). CONCLUSIONS AND RELEVANCE: Among patients hospitalized with acute respiratory failure, SRT compared with usual care did not decrease hospital LOS. TRIAL REGISTRATION: clinicaltrials.gov Identifier: NCT00976833.

Pain, agitation, and delirium guidelines: nurses' involvement in development and implementation.

The 2013 American College of Critical Care Medicine/Society of Critical Care Medicine clinical practice guidelines for the management of pain, agitation, and delirium in adult patients in the intensive care unit serves as a living example of nurses' involvement in the development and implementation of professional guidelines. Nurses who served on this guideline-writing panel describe their experiences. Specific examples from the pain, agitation, and delirium guidelines for care are used to explore the roles of the nurse leader, nurse informaticist, staff nurse, and nurse researcher in relationship to guideline implementation.

Associations between muscle-related cytokines and selected patient outcomes in the ICU.

INTRODUCTION: Systemic cytokines produced by contracting skeletal muscles may affect the onset and severity of intensive care unit (ICU)-acquired weakness after critical illness. AIMS: The purpose of this research was to determine the serum levels of interleukin (IL)-8, IL-15, and tumor necrosis factor-α (TNF-α) among patients receiving mechanical ventilation for >48 hr and examine the relationships of these myokines to outcomes of patient delirium, muscle strength, activities of daily living (ADLs), duration of mechanical ventilation, and length of ICU stay. METHODS: In this exploratory, repeated-measures interventional study, the 36 participants received 20 min of once-daily in-bed or out-of-bed activity using an established early progressive mobility protocol after physiologic stability had been demonstrated for >4 hr in the ICU. Blood samples were drawn on 3 consecutive days, beginning on the day of study enrollment, for serum cytokine quantification. RESULTS: IL-8, IL-15, and TNF-α were highly variable and consistently elevated in participants compared to normal healthy adults. About 1/3 of participants were positive for significant muscle weakness at discharge from ICU. Repeated values of mean postactivity IL-8 serum values were significantly associated only with ADL following ICU discharge. There were no significant associations with repeated values of mean postactivity IL-15 or TNF-α serum values and outcomes. CONCLUSION: Results provide preliminary data for exploring the potential effects of elevated serum values IL-8 and IL-15 in muscle health and TNF-α for muscle damage, including effect sizes to calculate the sample sizes needed for future studies.

An official American Thoracic Society Clinical Practice guideline: the diagnosis of intensive care unit-acquired weakness in adults.

RATIONALE: Profound muscle weakness during and after critical illness is termed intensive care unit-acquired weakness (ICUAW). OBJECTIVES: To develop diagnostic recommendations for ICUAW. METHODS: A multidisciplinary expert committee generated diagnostic questions. A systematic review was performed, and recommendations were developed using the Grading, Recommendations, Assessment, Development, and Evaluation (GRADE) approach. MEASUREMENT AND MAIN RESULTS: Severe sepsis, difficult ventilator liberation, and prolonged mechanical ventilation are associated with ICUAW. Physical rehabilitation improves outcomes in heterogeneous populations of ICU patients. Because it may not be feasible to provide universal physical rehabilitation, an alternative approach is to identify patients most likely to benefit. Patients with ICUAW may be such a group. Our review identified only one case series of patients with ICUAW who received physical therapy. When compared with a case series of patients with ICUAW who did not receive structured physical therapy, evidence suggested those who receive physical rehabilitation were more frequently discharged home rather than to a rehabilitative facility, although confidence intervals included no difference. Other interventions show promise, but fewer data proving patient benefit existed, thus precluding specific comment. Additionally, prior comorbidity was insufficiently defined to determine its influence on outcome, treatment response, or patient preferences for diagnostic efforts. We recommend controlled clinical trials in patients with ICUAW that compare physical rehabilitation with usual care and further research in understanding risk and patient preferences. CONCLUSIONS: Research that identifies treatments that benefit patients with ICUAW is necessary to determine whether the benefits of diagnostic testing for ICUAW outweigh its burdens.
