Brief summary
The m-CCRP randomized controlled trial will evaluate the efficacy of a collaborative critical care recovery program from acute respiratory failure (ARF) survivors in accomplishing the Institute of Healthcare Improvement's triple aims of better health, better care, at lower cost. Primary Aim: To assess the efficacy of m-CCRP in improving the QOL of ARF survivors compared to attention control at twelve months post hospital discharge. Secondary Aims: 1. To evaluate the efficacy of m-CCRP in improving cognitive, physical, and psychological function of ARF survivors at twelve months post hospital discharge when compared to attention control. 2. To evaluate the efficacy of m-CCRP in reducing health-care utilization, defined as time from enrollment to emergency department visits and/or hospital re-admission, by ARF survivors as compared to attention control at twelve months post hospital discharge.
Detailed description
Five million Americans require admission to intensive care units (ICU) annually due to life threatening illnesses, and this number is expected to rise.4 Two million of these ICU admissions are secondary to Acute Respiratory Failure (ARF) with more than half requiring mechanical ventilation. Greater than 50% of the patients with ARF who survive their ICU stay suffer from long-term morbidity in the form of functional disability, cognitive disability, major or minor depression, and anxiety. These complications negatively impact the quality of life (QOL) of ARF survivors, interfere with their physical and emotional recovery, and lead to long-term disability with less than half of ARF survivors returning to the work force. Ongoing care for ARF survivors has been estimated to cost $3.5 million per ARF survivor at 1 year. This constellation of ICU sequelae with attendant morbidity has been designated as the post-intensive care syndrome (PICS). There are community resources and rehabilitation services available to ARF survivors, but the current fragmented nature of our healthcare system is unable to integrate and coordinate care in order to provide the most meaningful recovery. The Institute of Medicine recommends the development of care coordination programs to deliver patient-centered and interdisciplinary-based medical care. Indiana University Center for Aging Research (IUCAR) has over 20 years of experience in delivering interdisciplinary, collaborative care through pragmatic interventions utilizing care coordinators. Care coordinator delivery models have improved care of patients with dementia, depression, functional decline and PICS. Our PICS clinic, the Critical Care Recovery Center (CCRC) was developed in 2011 to enhance cognitive, physical, and psychological recovery of ICU survivors. Since then, CCRC has provided care to over 200 survivors with a high burden of PICS (88% had cognitive impairment; 60% had depression). CCRC showed feasibility and initial efficacy in managing PICS. However given its traditional outpatient clinic structure, CCRC has limited physical access to ARF survivors, leading to delayed evaluation and an added travel burden on ARF survivors. Building from the experience of the CCRC and our other successful care coordinator based programs; we now propose a mobile model of post-ICU collaborative care with greater access to enhance the recovery of ARF survivors. The overarching aim of the proposed program is to improve the QOL of patients who survived an episode of ARF by maximizing their cognitive, physical, and psychological recovery utilizing a mobile care coordinator. The care coordinator will bring the intervention to the patient irrespective of the patient's physical location and will be supported by an interdisciplinary team of a critical care physician, a health services scientist, an ICU nurse, and a psychologist, with input from other consultants as needed. In addition, dynamic feedback through process measurement tools and care coordination support software will inform the recovery process. We propose to evaluate the efficacy of our collaborative care intervention termed the Mobile Critical Care Recovery Program (m-CCRP) through a randomized clinical trial among survivors of ARF.
Interventions
The m-CCRP revolves around the central figure of a care coordinator who will organize and align recovery resources. The care coordinator is a registered nurse whose scope of practice includes health coaching, case managing, community organizing, and nursing care provider. The m-CCRP support team will consist of a critical care physician (Dr. Khan), a geriatrician with expertise in collaborative care (Dr. Boustani), an ICU collaborative care nurse (Dr. Lasiter), and a psychologist (Dr. Unverzagt). This team will meet weekly with the care coordinator. Drs. Khan and Boustani will be accessible to the coordinator through phone or pager at all times.
Patients in this group will receive regular wellness calls from the research team.
