Natural Language Processing and Quality Assessment in Primary Care

2014-08-27 03:17:37 | BioPortfolio


The investigators propose to use a Natural Language Processing System (NLP) to provide an initial baseline report for primary care patients at risk for diabetes and cardiovascular complications that will include: a) evidence of foot exam documentation in the previous year; b) use of aspirin for cardiovascular risk reduction; and c) tobacco use. As part of a randomized trial, we plan to use a previously validated mailed survey (NCQA Provider Recognition Program) that requests information on the last foot exam, use of aspirin and tobacco. Patients who have been identified by NLP as not having had a foot exam will be randomized into treatment and control arms. Both arms will receive an informational letter; with a second mailing to nonresponders after one month, describing the key strategies for effective patient-physician communication during the clinical encounter. The treatment arm will also receive an informational letter and patient education brochure containing key messages about the importance of regular foot examinations. NLP will be repeated after 6 months to compare the impact of the patient education materials.

Medical and Biotech [MESH] Definitions

A condition of the feet produced by prolonged exposure of the feet to water. Exposure for 48 hours or more to warm water causes tropical immersion foot or warm-water immersion foot common in Vietnam where troops were exposed to prolonged or repeated wading in paddy fields or streams. Trench foot results from prolonged exposure to cold, without actual freezing. It was common in trench warfare during World War I, when soldiers stood, sometimes for hours, in trenches with a few inches of cold water in them. (Andrews' Diseases of the Skin, 8th ed, p27)

Activities and programs intended to assure or improve the quality of care in either a defined medical setting or a program. The concept includes the assessment or evaluation of the quality of care; identification of problems or shortcomings in the delivery of care; designing activities to overcome these deficiencies; and follow-up monitoring to ensure effectiveness of corrective steps.

The use of severity-of-illness measures, such as age, to estimate the risk (measurable or predictable chance of loss, injury or death) to which a patient is subject before receiving some health care intervention. This adjustment allows comparison of performance and quality across organizations, practitioners, and communities. (from JCAHO, Lexikon, 1994)

The concept concerned with all aspects of the quality, accessibility, and appraisal of health care and health care delivery.

Norms, criteria, standards, and other direct qualitative and quantitative measures used in determining the quality of health care.
