Improving Long-Term Outcomes Research for Acute Respiratory Failure
This project is funded by a NHLBI R24 grant for Investigator-Initiated Resource-Related Research Projects. This project aims to assist researchers studying acute respiratory distress syndrome (ARDS)/acute respiratory failure (ARF) patients in designing trials that appropriately evaluate long-term patient outcomes, in order to facilitate research aimed at reducing the public health burden of health impairments after these critical illnesses.This project includes: 1)creation and dissemination of a national Web-based database of validated and recommended survey instruments and clinical testing methods for evaluating ARDS/ARF survivors’ long-term physical, cognitive, and mental health outcomes; 2) development and dissemination of practical resources for maximizing retention of ARDS/ARF survivors in long-term, longitudinal research studies; and 3) evaluation, implementation and dissemination of statistical methods and programs for evaluating longitudinal functional outcomes in the presence of high patient mortality (“censoring due to death”).

Addressing Post-Intensive Care Syndrome (APICS): Multi-Center Prospective Cohort Study
Clinical advances have significantly reduced short-term mortality after critical illness. Given the growing population of survivors of critical illness, there is greater need to address Post-Intensive Care Syndrome (PICS), defined as new or worsened physical, cognitive and/or mental health impairments occurring after an intensive care unit (ICU) stay. ICU survivors are frequently readmitted to the hospital, commonly for preventable complications, suggesting potentially ineffective post-discharge treatment for PICS and other issues faced by these ICU survivors. We hypothesize that patients are not receiving the majority of their post-discharge plan; i.e., having “unmet needs” soon after discharge from hospital to home. This prospective, multi-center observational study of acute respiratory failure survivors will evaluate the relationship between these unmet needs within 1 month after hospital discharge to home and survivors’ poor subsequent outcomes.

Nutrition and EXercISe in Critical Illness (NEXIS)
This multi-centered randomized controlled trial investigates whether a novel early intervention combining Intravenous (IV) amino acids plus in-bed cycle ergometry exercise improves physical outcomes in critically ill patients. We hypothesize that this innovative approach will improve short-term physical functioning outcomes (primary outcome), as well as amino acid metabolism, body composition, and patient-reported outcomes at 6-month follow-up.

Novel Arm Restraint for Intubated Patients with Cognitive Impairment to Reduce Agitation, Sedation, and Immobility: Device Development and Multi-Center Randomized Trial
Physical restraints – commonly used to reduce the self-removal of endotracheal tubes, feeding tubes, and intravenous (IV) catheters – have major limitations. The most common restraints are soft wrist restraints that constrain movement of the wrist, elbow and shoulder. Especially in older patients, such restraints are associated with increased agitation and delirium, often leading clinicians to increase sedation medications. Unfortunately, such medications can further complicate the patient’s hospital stay, by prolonging bed rest, immobility and mechanical ventilation, as well as worsening associated muscle weakness and pressure ulcers.The Exersides™ restraint is a novel, adjustable arm restraint for mechanically ventilated patients, which permits arm movement while not permitting the hand to reach endotracheal or feeding tubes. The Exersides™ restraint was designed to minimally impact the upper extremity function of critically ill patients. We are refining the current Exersides™ prototype to ensure comfort, stability and functionality, and will formally evaluate the feasibility and potential benefit of Exersides™ restraints in ICU patients. Thereafter, we will conduct a multi-center, randomized cross-over trial comparing the Exersides™ with traditional restraints in older, critically-ill mechanically ventilated patients.

BEhavioral Activation and ReHABilitation For Acute Respiratory Failure Survivors (BEHAB)
This pilot randomized controlled trial (RCT) investigates the feasibility of a combined behavioral activation – rehabilitation (BA-R) intervention in acute respiratory failure survivors. While our primary outcome is feasibility of the proposed pilot RCT, we will also evaluate, as secondary outcomes, whether BA-R will significantly lower depressive symptoms and reduce impairments in physical functioning.

The Roles of Response Shift & Patient Expectations for Recovery after ARDS
Acute respiratory distress syndrome (ARDS) is a life-threatening illness that usually requires ICU care. ARDS survivors frequently experience new or worsening physical, cognitive, and/or mental health impairments that last for years. However some ARDS survivors adapt to new impairments over time and report improving quality of life not explained by improvements in their physical, cognitive, and mental health.This adaption phenomenon is knoexplained by improvements in their physical, cognitive, and mental health.This adaption phenomenon is known as “response shift.” We are exploring whether patient characteristics prior to ARDS are associated with the magnitude of response shift experienced after ICU discharge, as well as how psycho-social factors like social support, resilience, and survivors’ expectations for recovery impact quality of life.This research uses data from the NHLBI ARDS Network Long Term Outcome Study (ALTOS) containing hundreds of data elements per patient, as well as enrolling a new prospective cohort of ICU survivors to collect data on the association between patient expectations for recovery and perceived quality of life 6 months after hospital discharge.

Functional Electrical Stimulation (FES) Assisted Cycle Ergometry for Early Rehabilitation of Critically Ill Patients
This multi-centered randomized controlled trial investigates whether Functional Electrical Stimulation-Assisted Cycle Ergometry (FES-Cycling) delivered early during critical illness in mechanically ventilated patients decreases intensive care unit-acquired weakness (ICU-AW). This trial’s main outcome measures include muscle strength, muscle mass and physical functioning. In a sub-group of patients, biochemical and histological changes in muscles will be evaluated via muscle biopsy. Participants also will receive 6-month follow-up to evaluate their physical, cognitive and mental health outcomes.

Recovery of Muscle after ALI (ROMA)
This study investigates changes and recovery in muscle electrophysiology and function during critical illness in order to understand mechanisms through which critical illness and ICU therapies contribute to long-term impairments in muscle strength, physical function and quality of life. Participants are drawn from the ongoing NIH-funded ARDS Network randomized controlled trials and have long-term follow-up conducted as part of the ARDS Network Long-term Outcomes Study (ALTOS – see details above).

ARDSNet Long Term Outcomes Study (ALTOS)
This study examines the long-term patient outcomes, at 6 and 12 months after enrollment into four NIH-funded ARDS Network clinical trials for acute lung injury/acute respiratory distress syndrome (ALI/ARDS) patients. Long-term outcomes of interest include measures of physical, cognitive and mental health. Participant evaluations are done via a battery of validated surveys by phone (estimated sample size = 900 from 41 hospitals at 11 study sites across United States) and for a sub-set of participants, in-person evaluation is conducted (estimated sample size = 300 from 11 hospitals at 4 study sites).

This checklist was developed and used by Dr. Kamdar, Dr. Needham and collaborators as part of their Quality Improvement (QI) project for sleep in the Johns Hopkins Medical ICU (published in Critical Care Medicine. 2013; 41:800-809). This checklist describes the environmental modifications, non-pharmacologic sleep aids, and pharmacological guidelines implemented by ICU staff to improve and promote patient sleep in this QI project.
Use of Neuromuscular Electrostimulation (NMES) for Treatment or Prevention of ICU-Associated Weakness (NMES)
The purpose of this study is to investigate whether neuromuscular electrostimulation (NMES) will decrease ICU-associated weakness. The study is a randomized clinical trial to evaluate the efficacy of twice-daily NMES versus sham therapy, applied to the bilateral lower extremities, to reduce ICU-associated weakness in patients with acute respiratory failure.
