Utilizing the Newest Vital Sign (NVS) to Assess Health Literacy at a Regional Academic Medical Center's Family Medicine Clinic.

ABSTRACT

Researchers examined the correlation between the physician's subjective assessment of health literacy rates and actual health literacy rates among patients as determined by the Newest Vital Sign (NVS). A sample of n = 150 patients, 18 years of age or older, were verbally interviewed using NVS tool before seeing their physician. After the physician met with the patient, the physician was asked to measure that patient's level of health literacy on a Likert-type scale and a "yes/no" scale. Frequency and percentage statistics were performed in SPSS to describe the distributions of patient and physician responses. Between-subjects statistics were used. Analysis of the patient surveys revealed one in 4 patients has a high likelihood of low health literacy. Analysis revealed there were significant positive correlations between physician response to perception of a patient's low health literacy risk and NVS survey responses. Despite the risk of limited literacy, 97.3% of physicians perceived the patient to understand what the physician was saying. Physicians should use teach-back and other health literacy principles with each patient, regardless of perceived risk.
