Gaps in public preparedness to be a substitute decision-maker and the acceptability of high school education on resuscitation and end-of-life care: a mixed-methods study.
Article in CMAJ open. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundWhen a patient is incapable of making medical decisions for him- or herself, a substitute decision-maker makes choices according to the patient's previously expressed wishes, values and beliefs; however, little is known about public readiness to act as a substitute decision-maker in Canada. Our primary objective was to measure public self-reported preparedness to act as a substitute decision-maker, and explore the attitudes, barriers and enablers associated with preparedness.
methodsFrom November 2017 to June 2018, we conducted a mixed-methods street intercept survey at 12 pedestrian areas in Ottawa, Ontario. We used descriptive statistics and logistic regression analysis to assess predictors of perceived preparedness to be a substitute decision-maker and determine support for high school education. We analyzed qualitative interview questions using inductive thematic analysis.
resultsOf the 626 eligible respondents, 196 refused to participate, leaving 430 participants (response rate 68.7%). A total of 404 surveys (94.0%) were fully complete with no missing data. The respondents were mostly female (243 [56.5%]) and residents of Ontario (364 [84.6%]). The average age was 33.9 years. Although 314 respondents (73.0%) felt prepared to be a substitute decision-maker, 194 (45.1%) reported never having had meaningful conversations with loved ones to understand their wishes in the event of critical illness. A total of 293 participants (68.1%) identified important barriers to feeling prepared. Most respondents (309 [71.9%]) agreed that high school students should learn about being a substitute decision-maker, citing age appropriateness, potential societal benefit and improved decision-making, while cautioning the need to respect different maturity levels, cultures and experiences.
interpretationhe lack of conversation between loved ones reveals a gap between perceived and actual preparedness to be a substitute decision-maker for a loved one with a critical illness. The overall acceptability of high school education warrants further exploration.
