Researching the Appropriateness of Care in the Complementary and Integrative Health Professions Part 5: Using Patient Records: Selection, Protection, and Abstraction.

OBJECTIVES: The purpose of this paper is to describe the 4-step process (consent, selection, protection, and abstraction) of acquiring a large sample of chiropractic patient records from multiple practices and subsequent data abstraction. METHODS: From April 2017 to December 2017, RAND acquired patient records from 99 chiropractic practices across the United States. The records included patients enrolled in a survey e-study (prospective sample) and a random sample of all clinic patients (retrospective sample) with chronic back or neck pain. Clinic staff were trained to collect the sample, scan, and transfer the records. We designed an online data collection tool for abstraction. Protocols were instituted to protect patient confidentiality. Doctors of chiropractic were selected and trained as abstractors, and a system was established to monitor data collection. RESULTS: In compliance with data protection protocols, 3603 patient records were scanned, including 1475 in the prospective sample and 2128 in the random sample. A total of 1716 patients (prospective sample) consented to having their records scanned, but only 1475 could be retrieved. Of records scanned, 19% were unusable owing to illegibility, no care during the period of interest, or poor scanning. The abstractor interrater reliability for appropriateness of care decisions was fair to moderate (κ .38-.48). CONCLUSION: The acquisition, handling, and abstraction of a large sample of chiropractic records was a complex task with challenges that necessitated adapting planned approaches. Of the records abstracted, many revealed incomplete provider documentation regarding the details of and rationale for care. Better documentation and more standardized record keeping would facilitate future research using patient records.

A Psychometric Study of the Modified Bridges for Newborns Screening Tool.

Welcome Baby, a program that First 5 Los Angeles (First 5 LA) sponsors, provides new mothers with supportive services intended to create enriching environments for their children. To identify mothers in need of these services, First 5 LA employs hospital liaisons who administer a maternal risk assessment tool, the Modified Bridges for Newborns screening tool, during postpartum interviews of mothers. First 5 LA uses risk assessment scores from the Modified Bridges to classify mothers as low, moderate, or high risk; high-risk mothers are eligible for additional supportive services that are not available to low- and moderate-risk mothers. This article describes RAND Corporation work evaluating the psychometric characteristics of the Modified Bridges.
