Physical Function Trajectories in Survivors of Acute Respiratory Failure.

ABSTRACT: RATIONALE:Survivorship from critical illness has improved; however, factors mediating the functional recovery of persons experiencing a critical illness remain incompletely understood. OBJECTIVES:To identify groups of acute respiratory failure (ARF) survivors with similar patterns of physical function recovery after discharge and to determine the characteristics associated with group membership in each physical function trajectory group. METHODS:We performed a secondary analysis of a randomized controlled trial, using group-based trajectory modeling to identify distinct subgroups of patients with similar physical function recovery patterns after ARF. Chi-square tests and one-way analysis of variance were used to determine which variables were associated with trajectory membership. A multinomial logistic regression analysis was performed to identify variables jointly associated with trajectory group membership. RESULTS:A total of 260 patients enrolled in a trial evaluating standardized rehabilitation therapy in patients with ARF and discharged alive (NCT00976833) were included in this analysis. Physical function was quantified using the Short Physical Performance Battery at hospital discharge and 2, 4, and 6 months after enrollment. Latent class analysis of the Short Physical Performance Battery scores identified four trajectory groups. These groups differ in both the degree and rate of physical function recovery. A multinomial logistic regression analysis was performed using covariates that have been previously identified in the literature as influencing recovery after critical illness. By multinomial logistic regression, age (P?

Project description:Rationale: Increasingly, patients are surviving acute respiratory failure (ARF), prompting the need to better understand standardized outcome measures commonly used during ARF follow-up studies. Objectives: Investigate standardized outcome measures (patient-reported physical and mental health measures, and cognitive testing) compared with findings from semistructured, qualitative interviews. Methods: As part of two ARF multicenter follow-up studies, standardized outcome measures were obtained, followed by qualitative evaluation via an in-depth, semistructured interview conducted and coded by two independent researchers. Qualitative interviews revealed the following post-ARF survivorship themes: physical impairment; anxiety, depression, and post-traumatic stress disorder symptoms; and cognitive impairment. Scores from standardized measures related to these themes were compared for ARF survivors reporting versus not reporting these themes in their qualitative interviews. Results: Of 59 invited ARF survivors, 48 (81%) completed both standardized outcome measures and qualitative interviews. Participants' median (interquartile range) age was 53 (43-64) years; 54% were female, and 88% were living independently before hospitalization. The two independent reviewers classifying the presence or absence of themes from the qualitative interviews had excellent agreement (??=?0.80). There were significantly worse scores on standardized outcome measures for survivors reporting (vs. not reporting) physical and mental health impairments in their qualitative interviews. However, standardized cognitive test scores did not differ between patients reporting versus not reporting cognitive impairments in their qualitative interviews. Conclusions: These findings support the use of recommended, commonly used standardized outcome measures for physical and mental health impairments in ARF survivorship research. However, caution is needed in interpreting self-reported cognitive function compared with standardized cognitive testing.

Project description:The proportion of survivors of acute respiratory failure is growing; yet, many do not regain full function and require prolonged admission in an acute or post-acute care facility. Little is known about their trajectory of functional recovery. We sought to determine whether prolonged admission influenced the trajectory of physical function recovery and whether patient age modified the recuperation rate.We performed a secondary analysis of a randomized clinical trial of intensive physical therapy for patients with acute respiratory failure requiring mechanical ventilation for ?4 days. The primary outcome was Continuous Scale Physical Functional Performance, short form (CS-PFP-10), score. Predictor variables included prolonged admission in an acute or post-acute care facility at 1 month, time, and patient age. To determine whether the association between admission and functional outcome varied over time, a multivariable mixed effects linear regression model was fit using an interaction between prolonged admission and time with a primary outcome of total CS-PFP-10 score.Of the 89 patients included, 56% (50 of 89) required prolonged admission. At 1 month, patients who remained admitted had CS-PFP-10 scores that were 20.1 (CI 10.4-29.8) points lower (p?<?0.0001) than patients who were discharged to home. However, there was no difference in the rate at which physical function improved from 3 to 6 months for patients who required prolonged admission compared with those who returned home (p?=?0.24 for interaction between prolonged admission and time). Adjusted for age, Acute Physiology and Chronic Health Evaluation II score, and sex, both groups had CS-PFP-10 scores that were 8.2 (CI 4.5-12.0) points higher at 6 months than at 3 months (p?<?0.0001). For each additional year in patient age, CS-PFP-10 recovered 0.36 points slower (95% CI 0.12-0.61; p?=?0.004).Patients who require prolonged admission after acute respiratory failure have significantly lower physical functional performance than patients who return home. However, the rates of physical functional recovery between the two groups do not differ. The majority of survivors do not recover sufficiently to achieve functional independence by 6 months. Older age negatively influences the trajectory of functional recovery.ClinicalTrials.gov, NCT01058421 . Registered on 26 January 2010.

Project description:BackgroundDysphagia with subsequent aspiration occurs in up to 60% of acute respiratory failure (ARF) survivors. Accurate bedside tests for aspiration can reduce aspiration-related complications while minimizing delay of oral nutrition. In a cohort of ARF survivors, we determined the accuracy of the bedside swallowing evaluation (BSE) and its components for detecting aspiration.MethodsPatients who were extubated after at least 24hours of mechanical ventilation were eligible for enrollment. Within 3 days of extubation, patients underwent comprehensive BSE including 3-oz water swallowing test (3-WST), followed by a criterion standard test for aspiration, flexible endoscopic evaluation of swallowing (FEES).ResultsForty-five patients were included in the analysis. Median patient age was 55years (interquartile range, 47-65). Median duration of mechanical ventilation was 3.3days (interquartile range 1.8-6.0). Fourteen patients (31%) aspirated on FEES. Physical examination findings on BSE and abnormal swallowing during trials of different consistencies were variably associated with aspiration. Compared with FEES, the 3-WST yielded a sensitivity of 77% (95% confidence interval [CI], 50%-92%), specificity of 65% (95% CI, 47%-79%), and an area under the receiver operating characteristic curve (AUC) of 0.71; a speech language pathologist's recommendation for altered diet yielded a sensitivity of 86% (95% CI, 60%-96%), a specificity of 52% (95% CI, 35%-68%), and an AUCof 0.69; an speech language pathologist's recommendation for nil per os (nothing by mouth) yielded a sensitivity of 50% (95% CI, 27%-73%), a specificity of 94% (95% CI, 79%-98%), and an AUCof 0.72.ConclusionsThe BSE and its components, including the 3-WST, demonstrated variable accuracy for aspiration in survivors of ARF. Investigation to determine the optimal noninvasive test for aspiration in ARF survivors is warranted.Clinical trials registrationClinicalTrials.gov identifier: NCT02363686, Aspiration in Acute Respiratory Failure Survivors.
