COVID-19 Project ECHO for Nursing Homes: A Patient-centered, Randomized-controlled Trial to Implement Infection Control, United States, 2021 (ICPSR 38769)
Methods for Prioritizing Surrogate Desired Health Outcomes for Patients [Methods Study], Washington, DC and Maryland, 2013-2018 (ICPSR 39516)
Children with intellectual and cognitive disabilities often have problems with reasoning, learning, and problem solving. With such challenges, caregivers may have to make choices for their children about their health care and treatments. These children may need such help into young adulthood.
In this study, the research team wanted to find out what matters most to caregivers about their children's care. Caregivers had children with an intellectual or cognitive disability plus a mental health condition, such as depression or anxiety. The team interviewed caregivers about their preferences. Then the team used this information to design a survey. A larger group of caregivers filled out the survey.
Targeted Interventions to Prevent Chronic Low Back Pain in High Risk Patients: A Multi-Site Pragmatic Randomized Controlled Trial (TARGET Trial), 4 U.S. cities, 2016-2019 (ICPSR 38145)
The TARGET (Targeted Interventions to Prevent Chronic Low Back Pain in High-Risk Patients) Trial was a primary care-based, multisite, cluster randomized, pragmatic trial comparing guideline-based care (GBC) to GBC + referral to Psychologically Informed Physical Therapy (PIPT) for patients presenting with acute lower back pain (LBP) and identified as high risk for persistent disabling symptoms. Chronic lower back pain (LBP) is defined as a response of "more than three months" to question 1, and a response of "half the days or more than half the days" in the past 6 months to question 2. See Appendix 1 for the LBP Questionnaire in the Protocol report.
Study sites included primary care clinics within each of four geographical regions in the United States, with clinics randomized to either GBC or GBC+PIPT. Acute LBP patients at all clinics were risk stratified (high, medium, low) using the STarT Back Tool. The primary outcomes were the presence of chronic LBP and LBP-related functional disability determined by the Oswestry Disability Index at 6 months. Secondary outcomes were LBP-related processes of health care and utilization of services over 12 months, determined through electronic medical records.
Study enrollment began in May 2016 and concluded in June 2018. The trial was powered to include at least 1,860 high-risk patients in the cluster-randomized controlled trial cohort. A prospective observational cohort of approximately 6,900 low and medium-risk acute LBP patients was enrolled concurrently.
This data collection contains a single data file with 223 variables and 9,730 cases. The number of respondents at each of the study locations were:
- Boston Medical Center: 997 respondents
- Intermountain Health (Salt Lake City): 2,094 respondents
- Johns Hopkins University (Baltimore): 1,615 respondents
- University of Pittsburg Medical Center: 5,024 respondents
