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 (κ = 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.

Objectives To identify staff-reported factors and perceptions that influenced implementation and sustainability of an early mobilization program (PICU Up!) in the PICU. Design A qualitative study using semistructured phone interviews to characterize interprofessional staff perspectives of the PICU Up! program. Following data saturation, thematic analysis was performed on interview transcripts. Setting Tertiary-care PICU in the Johns Hopkins Hospital, Baltimore, MD. Subjects Interprofessional PICU staff. Interventions None. Measurements and main results Fifty-two staff members involved in PICU mobilization across multiple disciplines were interviewed. Three constructs emerged that reflected the different stages of PICU Up! program execution: 1) factors influencing the implementation process, 2) staff perceptions of PICU Up!, and 3) improvements in program integration. Themes were developed within these constructs, addressing facilitators for PICU Up! implementation, cultural changes for unitwide integration, positive impressions toward early mobility, barriers to program sustainability, and refinements for more robust staff and family engagement. Conclusions Three years after implementation, PICU Up! remains well-received by staff, positively influencing role satisfaction and PICU team dynamics. Furthermore, patients and family members are perceived to be enthusiastic about mobility efforts, driving staff support. Through an ongoing focus on stakeholder buy-in, interprofessional engagement, and bundled care to promote mobility, the program has become part of the culture in the Johns Hopkins Hospital PICU. However, several barriers remain that prevent consistent execution of early mobility, including challenges with resource management, sedation decisions, and patient heterogeneity. Characterizing these staff perceptions can facilitate the development of solutions that use institutional strengths to grow and sustain PICU mobility initiatives.

With decreasing mortality in PICUs, a growing number of survivors experience long-lasting physical impairments. Early physical rehabilitation and mobilization during critical illness are safe and feasible, but little is known about the prevalence in PICUs. We aimed to evaluate the prevalence of rehabilitation for critically ill children and associated barriers.National 2-day point prevalence study.Eighty-two PICUs in 65 hospitals across the United States.All patients admitted to a participating PICU for greater than or equal to 72 hours on each point prevalence day.None.The primary outcome was prevalence of physical therapy- or occupational therapy-provided mobility on the study days. PICUs also prospectively collected timing of initial rehabilitation team consultation, clinical and patient mobility data, potential mobility-associated safety events, and barriers to mobility. The point prevalence of physical therapy- or occupational therapy-provided mobility during 1,769 patient-days was 35% and associated with older age (adjusted odds ratio for 13-17 vs3 yr, 2.1; 95% CI, 1.5-3.1) and male gender (adjusted odds ratio for females, 0.76; 95% CI, 0.61-0.95). Patients with higher baseline function (Pediatric Cerebral Performance Category, ≤ 2 vs2) less often had rehabilitation consultation within the first 72 hours (27% vs 38%; p0.001). Patients were completely immobile on 19% of patient-days. A potential safety event occurred in only 4% of 4,700 mobility sessions, most commonly a transient change in vital signs. Out-of-bed mobility was negatively associated with the presence of an endotracheal tube (adjusted odds ratio, 0.13; 95% CI, 0.1-0.2) and urinary catheter (adjusted odds ratio, 0.28; 95% CI, 0.1-0.6). Positive associations included family presence in children less than 3 years old (adjusted odds ratio, 4.55; 95% CI, 3.1-6.6).Younger children, females, and patients with higher baseline function less commonly receive rehabilitation in U.S. PICUs, and early rehabilitation consultation is infrequent. These findings highlight the need for systematic design of rehabilitation interventions for all critically ill children at risk of functional impairments.

Background: Health care continuing education conferences are important educational events that present opportunities for structured learning, interactive sharing, and professional networking. Conference presenters frequently cite published literature, such as clinical trials, to supply an evidence-based foundation, with presenters’ slides often shared with conference attendees. By using social media, these conferences can have greater impact, assist in supporting evidence-based clinical practice, and increase stakeholder engagement.Case Presentation: The authors present a case of embedding a health sciences librarian into the Annual Johns Hopkins Critical Care Rehabilitation Conference. The librarian served multiple roles, including social media ambassador, conference exhibitor, and presenter. We explore how these roles contributed to the field of early rehabilitation research through information dissemination and education. We also address best practices for librarian support of the conference, with a discussion of tools, platforms, and work flows that were beneficial.Conclusions: Librarian integration facilitated education about bibliographic literature database content, database searching, critical appraisal, and reporting of search methodology. Additionally, the librarian contributed to real-time distribution of scholarly literature through proficiency with web platforms, citation management programs, and social media. Librarians’ expertise in information organization and dissemination, as well as various technology platforms, make them a valuable addition to health care conferences.

Objective Psychiatric illness complicates the assessment of alcohol and sedative withdrawal (ASW). This study measured the diagnostic characteristics of the Revised Clinical Institute Withdrawal Alcohol Assessment (CIWA-Ar) and the Brief Alcohol Withdrawal Scale (BAWS) compared with a reference standard in patients with psychiatric illness and evaluated their administration time. Methods This prospective quality improvement (QI) project conducted in November, 2016 evaluated 35 consecutive unique patients in psychiatric settings. Each patient was evaluated on 1 occasion, sequentially by 2 independent examiners with the CIWA-Ar and BAWS. A Diagnostic Statistical Manual of Mental Disorders, Fifth Edition diagnosis of ASW derived after medical record review by 2 psychiatrists blind to the screening results served as a reference standard. Psychometric properties of the CIWA-Ar and BAWS were measured against the reference. Results Nineteen (54%) patients had ASW diagnosis by the reference standard. The sensitivity (95% confidence interval [CI]) of the CIWA-Ar was 47% (25%-71%) at a cut-off score ≥8; sensitivity of the BAWS was 79% (54%-94%) at a cut-off score ≥3. Specificity (95% CI) for CIWA-Ar and BAWS was 88% (62%-98%) and 88% (62%-98%), respectively. Administration times (interquartile range) for the CIWA-Ar and BAWS were 120 (60-180) and 65 (50-75) seconds, respectively. Receiver operator characteristic area under the curve for CIWA-Ar was 0.77 and for BAWS was 0.76 (P = 0.86). Conclusion Both instruments performed similarly in assessing for mild to moderate ASW in a sample of patients with psychiatric illness. The BAWS took 65 seconds to administer-almost half as much time as the CIWA-Ar.

Background Acute respiratory failure survivors experience depression symptoms and new impairments in physical function. Behavioural activation, an evidence-based nonpharmacological treatment for depression, combined with physical rehabilitation, is a promising intervention. Notably, mHealth applications (Apps) are potentially effective methods of delivering home-based interventions. Objectives The objective of this study was to evaluate the usability and acceptability of a prototype App to deliver a combined, home-based behavioural activation and rehabilitation intervention to acute respiratory failure survivors. Methods A prospective user-preference study was conducted with acute respiratory failure survivors and self-designated care partners. Survivors were adults with at least mild depression symptoms before hospital discharge who received mechanical ventilation in the intensive care unit for ≥24 h. Survivors and care partners reviewed the App during a single in-person home visit and completed the System Usability Scale (range: 0–100; score >73 considered “good”) and a semistructured interview. Results Ten patient/care partner dyads completed study. The median [interquartile range] patient age was 50 [40–64] years, and 50% were female. The median System Usability Scale scores among patients and care partners were 76 [68–83] and 88 [75–94], respectively. Qualitative feedback supported usability and acceptability of the App, with three themes reported: (1) stigma associated with depression, (2) App as a motivator for recovery, and (3) App providing multidisciplinary support for survivor and care partner. Conclusions A mobile App prototype designed to deliver a combined behavioural activation and rehabilitation intervention was usable and acceptable to survivors of acute respiratory failure and their care partners. Given the reported stigma associated with depression, the self-directed App may be particularly valuable for motivation and multidisciplinary support.

Negative physician attitudes toward patients with substance use disorders (SUD) pose a significant barrier to treatment. This study tests the overall and intra-individual change in attitudes of second year medical students after exposure to a 15 hour SUD course. Two cohorts of second year medical students (2014 and 2015) responded to an anonymous 13-item previously published survey exploring personal views regarding patients with SUD using a four-point Likert scale. Students were surveyed one day before and up to one month after course completion. Survey items were grouped into the following categories: treatment optimism/confidence in intervention, moralism, and stereotyping. The Wilcoxon nonparametric signed-rank test (α=0.05) was used to compare the pre- and post- survey responses. In 2014 and 2015 respectively, 118 and 120 students participated in the SUD course with pre- and post-response rates of 89.0% and 75.4% in 2014 and 95.8% and 97.5% in 2015. Of the 13 survey questions, paired responses to eight questions showed a statistically significant positive change in attitudes with a medium (d = 0.5) to large effect size (d = 0.8). Items focused on treatment optimism and confidence in treatment intervention reflected a positive attitude change, as did items associated with stereotyping and moralism. These results support the hypothesis that exposure to a course on SUD was associated with positive change in medical students’ attitudes toward patients with SUD.

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.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.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.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.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.

Despite the historical precedent of mobilizing critically ill patients, bed rest is common practice in ICUs worldwide, especially for mechanically ventilated patients. ICU-acquired weakness is an increasingly recognized problem, with sequelae that may last for months and years following ICU discharge. The combination of critical illness and bed rest results in substantial muscle wasting during an ICU stay. When initiated shortly after the start of mechanical ventilation, mobilization and rehabilitation can play an important role in decreasing the duration of mechanical ventilation and hospital stay and improving patients' return to functional independence. This review summarizes recent evidence supporting the safety, feasibility, and benefits of early mobilization and rehabilitation of mechanically ventilated patients and presents a brief summary of future directions for this field.

Knowledge-related barriers to safely implement early rehabilitation programs in intensive care units (ICUs) may be overcome via targeted education. The purpose of this study was to evaluate the effectiveness of an interactive educational session on short-term knowledge of clinical decision-making for safe rehabilitation of patients in ICUs.A case-based teaching approach, drawing from published safety recommendations for initiation of rehabilitation in ICUs, was used with a multidisciplinary audience. An audience response system was incorporated to promote interaction and evaluate knowledge before vs. after the educational session.Up to 175 audience members, of 271 in attendance (129 (48%) physical therapists, 51 (19%) occupational therapists, 31 (11%) nursing, 14 (5%) physician, 46 (17%) other), completed both the pre- and post-test questions for each of the six unique patient cases. In four of six patient cases, there was a significant (p 0.001) increase in identifying the correct answer regarding initiation of rehabilitation activities. This learning effect was similar irrespective of participants' years of experience and clinical discipline.An interactive, case-based, educational session may be effective for increasing short-term knowledge, and identifying knowledge gaps, regarding clinical decision-making for safe rehabilitation of patients in ICUs. Implications for Rehabilitation Lack of knowledge regarding the safety considerations for early rehabilitation of ICU patients is a barrier to implementing early rehabilitation. Interactive educational formats, such as the use of audience response systems, offer a new method of teaching and instantly assessing learning of clinically important information. In a small study, we have shown that an interactive, case-based educational format may be used to effectively teach clinical decision-making for the safe rehabilitation of ICU patients to a diverse audience of clinicians.

The remodeling of the larval fat body is observed in many insects during metamorphosis, but little is known about the physiological importance or the regulation of this process. In Drosophila melanogaster, fat-body remodeling involves the dissociation of the fat body into individual fat cells, which persist throughout pupal development but are later removed by cell death in the young adult. Inhibition of fat-body dissociation is associated with pharate adult lethality and thus is likely to be an essential developmental event. As a start toward understanding the role of fat-body remodeling in the life history of insects, we carried out a detailed study of fat-body disassociation in D. melanogaster using fluorescent microscopy, and tested whether this process is mediated by hemocytes as proposed for fat-body remodeling in Sarcophaga peregrina. We identified and correlated stereotypic events in fat-body dissociation with developmental changes during metamorphosis, and have demonstrated by cell ablation studies that fat-body remodeling in D. melanogaster is a hemocyte independent process.

Rehabilitation started early during an intensive care unit (ICU) stay is associated with improved outcomes and is the basis for many quality improvement (QI) projects showing important changes in practice. However, little evidence exists regarding whether such changes are sustainable in real-world practice.To evaluate the sustained effect of a quality improvement project on the timing of initiation of active physical therapy intervention in patients with acute lung injury (ALI).This was a pre-post evaluation using prospectively collected data involving consecutive patients with ALI admitted pre-quality improvement (October 2004-April 2007, n = 120) versus post-quality improvement (July 2009-July 2012, n = 123) from a single medical ICU.The primary outcome was time to first active physical therapy intervention, defined as strengthening, mobility, or cycle ergometry exercises. Among ICU survivors, more patients in the post-quality improvement versus pre-quality improvement group received physical therapy in the ICU (89% vs. 24%, P0.001) and were able to stand, transfer, or ambulate during physical therapy in the ICU (64% vs. 7%, P0.001). Among all patients in the post-quality improvement versus pre-quality improvement group, there was a shorter median (interquartile range) time to first physical therapy (4 [2, 6] vs. 11 d [6, 29], P0.001) and a greater median (interquartile range) proportion of ICU days with physical therapy after initiation (50% [33, 67%] vs. 18% [4, 47%], P = 0.003). In multivariable regression analysis, the post-quality improvement period was associated with shorter time to physical therapy (adjusted hazard ratio [95% confidence interval], 8.38 [4.98, 14.11], P0.001), with this association significant for each of the 5 years during the post-quality improvement period. The following variables were independently associated with a longer time to physical therapy: higher Sequential Organ Failure Assessment score (0.93 [0.89, 0.97]), higher FiO2 (0.86 [0.75, 0.99] for each 10% increase), use of an opioid infusion (0.47 [0.25, 0.89]), and deep sedation (0.24 [0.12, 0.46]).In this single-site, pre-post analysis of patients with ALI, an early rehabilitation quality improvement project was independently associated with a substantial decrease in the time to initiation of active physical therapy intervention that was sustained over 5 years. Over the entire pre-post period, severity of illness and sedation were independently associated with a longer time to initiation of active physical therapy intervention in the ICU.

Objective To describe methodology used to diagnose delirium in research studies evaluating delirium detection tools. Methods The authors used a survey to address reference rater methodology for delirium diagnosis, including rater characteristics, sources of patient information, and diagnostic process, completed via web or telephone interview according to respondent preference. Participants were authors of 39 studies included in three recent systematic reviews of delirium detection instruments in hospitalized patients. Results Authors from 85% (N = 33) of the 39 eligible studies responded to the survey. The median number of raters per study was 2.5 (interquartile range: 2–3); 79% were physicians. The raters' median duration of clinical experience with delirium diagnosis was 7 years (interquartile range: 4–10), with 5% having no prior clinical experience. Inter-rater reliability was evaluated in 70% of studies. Cognitive tests and delirium detection tools were used in the delirium reference rating process in 61% (N = 21) and 45% (N = 15) of studies, respectively, with 33% (N = 11) using both and 27% (N = 9) using neither. When patients were too drowsy or declined to participate in delirium evaluation, 70% of studies (N = 23) used all available information for delirium diagnosis, whereas 15% excluded such patients. Conclusion Significant variability exists in reference standard methods for delirium diagnosis in published research. Increasing standardization by documenting inter-rater reliability, using standardized cognitive and delirium detection tools, incorporating diagnostic expert consensus panels, and using all available information in patients declining or unable to participate with formal testing may help advance delirium research by increasing consistency of case detection and improving generalizability of research results.

Purpose Critical illness survivors commonly have impaired physical functioning. Physical therapy interventions delivered in the intensive care unit can reduce these impairments, but the safety of such interventions within routine clinical practice requires greater investigation. Materials and Methods We conducted a prospective observational study of routine physical therapy from July 2009 through December 2011 in the Johns Hopkins Hospital Medical Intensive Care Unit in Baltimore, MD. The incidence of 12 types of physiological abnormalities and potential safety events associated with physical therapy were monitored and evaluated for any additional treatment, cost, or length of stay. Results Of 1787 admissions of at least 24 hours, 1110 (62%) participated in 5267 physical therapy sessions conducted by 10 different physical therapists on 4580 patient-days. A total of 34 (0.6%) sessions had a physiological abnormality or potential safety event, with the most common being arrhythmia (10 occurrences, 0.2%) and mean arterial pressure greater than 140 mm Hg (8 occurrences; 0.2%) and less than 55 mm Hg (5 occurrences; 0.1%). Only 4 occurrences (0.1%) required minimal additional treatment or cost, without additional length of stay. Conclusions In this large, single-center study, routine care physical therapy interventions were safe for critically ill patients.

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.

During metamorphosis, holometabolous insects eliminate obsolete larval tissues via programmed cell death. In contrast, tissues required for further development are retained and often remodeled to meet the needs of the adult fly. The larval fat body is involved in fueling metamorphosis, and thus it escapes cell death and is instead remodeled during prepupal development. The molecular mechanisms by which the fat body escapes programmed cell death have not yet been described, but it has been established that fat-body remodeling requires 20-hydroxyecdysone (20E) signaling. We have determined that 20E signaling is required within the fat body for the cell-shape changes and cell detachment that are characteristic of fat-body remodeling. We demonstrate that the nuclear hormone receptor ßFTZ-F1 is a key modulator of 20E hormonal induction of fat body remodeling and Matrix metalloproteinase 2 (MMP2) expression in the fat body. We show that induction of MMP2 expression in the fat body requires 20E signaling, and that MMP2 is necessary and sufficient to induce fat-body remodeling.
