Topic: Risk, prevention and care in population studies
Background Decision making at the end of life is frequently complex and often filled with uncertainty. We hypothesized that people with limited health literacy would have more uncertainty about end-of-life decision making than people with adequate literacy. We also hypothesized that video images would decrease uncertainty. Design . Before and after oral survey. Participants. Subjects presenting to their primary care physicians. Methods Subjects were asked about their preferences for end-of-life care after they heard a verbal description of advanced dementia and were asked to rate the level of their uncertainty. Subjects then viewed a video of a patient with advanced dementia and were asked again about their preferences and uncertainty. Uncertainty was measured using the Decisional Conflict Scale with score ranges from 3 (high uncertainty) to 15 (no uncertainty). Health literacy was measured using the Rapid Estimate of Adult Literacy in Medicine, and subjects were divided into 3 literacy categories: low (0-45, 6th grade and below), marginal (46- 60, 7th-8th grade), and adequate (61-66, 9th grade and above). Results A total of 146 patients completed the interview. Prior to the video, the average uncertainty scores for subjects with low, marginal, and adequate health literacy were 10.8, 12.4, and 13.5, respectively (P < 0.0001). After the video, the 3 groups had similar uncertainty about their decisions. The average uncertainty scores for subjects with low, marginal, and adequate health literacy were 13.6, 14.1, and 14.5, respectively (P = 0.046). Conclusions Subjects with limited health literacy expressed more uncertainty about their preferences for end-of-life care than did subjects with adequate literacy. Our video decision aid improved end-of-life decision making by decreasing uncertainty regarding subjects' preferences, especially for those with limited literacy.

How this study scored 45/100
Published in a peer-reviewed journal. Scored zero for study design, effect reported and randomized / blinded because the record does not state it. We have no data on journal's citation record, times cited, citations per year, impact for its field and year, cited by studies here, still being cited, senior author's track record, institution's track record and multicenter collaboration, so those were left out: it earned 26 of the 58 points we could judge it on, which is 45 out of 100.
