BackgroundEffective use of a patient decision aid (PtDA) can be affected by the user’s health literacy and the PtDA’s characteristics. Systematic reviews of the relevant literature can guide PtDA developers to attend to the health literacy needs of patients. The reviews reported here aimed to assess:1. a) the effects of health literacy / numeracy on selected decision-making outcomes, and b) the effects of interventions designed to mitigate the influence of lower health literacy on decision-making outcomes, and2. the extent to which existing PtDAs a) account for health literacy, and b) are tested in lower health literacy populations.MethodsWe reviewed literature for evidence relevant to these two aims. When high-quality systematic reviews existed, we summarized their evidence. When reviews were unavailable, we conducted our own systematic reviews.ResultsAim 1: In an existing systematic review of PtDA trials, lower health literacy was associated with lower patient health knowledge (14 of 16 eligible studies). Fourteen studies reported practical design strategies to improve knowledge for lower health literacy patients. In our own systematic review, no studies reported on values clarity per se, but in 2 lower health literacy was related to higher decisional uncertainty and regret. Lower health literacy was associated with less desire for involvement in 3 studies, less question-asking in 2, and less patient-centered communication in 4 studies; its effects on other measures of patient involvement were mixed. Only one study assessed the effects of a health literacy intervention on outcomes; it showed that using video to improve the salience of health states reduced decisional uncertainty. Aim 2: In our review of 97 trials, only 3 PtDAs overtly addressed the needs of lower health literacy users. In 90% of trials, user health literacy and readability of the PtDA were not reported. However, increases in knowledge and informed choice were reported in those studies in which health literacy needs were addressed.ConclusionLower health literacy affects key decision-making outcomes, but few existing PtDAs have addressed the needs of lower health literacy users. The specific effects of PtDAs designed to mitigate the influence of low health literacy are unknown. More attention to the needs of patients with lower health literacy is indicated, to ensure that PtDAs are appropriate for lower as well as higher health literacy patients.

BackgroundDecision aids (DA) to assist patients in evaluating treatment options and sharing in decision making have proliferated in recent years. Most require high literacy and do not use plain language principles. We describe one of the first attempts to design a decision aid using principles from reading research and document design. The plain language DA prototype addressed treatment decisions for localized prostate cancer. Evaluation assessed impact on knowledge, decisions, and discussions with doctors in men newly diagnosed with prostate cancer.MethodsDocument development steps included preparing an evidence-based DA in standard medical parlance, iteratively translating it to emphasize shared decision making and plain language in three formats (booklet, Internet, and audio-tape). Scientific review of medical content was integrated with expert health literacy review of document structure and design. Formative evaluation methods included focus groups (n = 4) and survey of a new sample of men newly diagnosed with prostate cancer (n = 60), compared with historical controls (n = 184).ResultsA transparent description of the development process and design elements is reported. Formative evaluation among newly diagnosed prostate cancer patients found the DA to be clear and useful in reaching a decision. Newly diagnosed patients reported more discussions with doctors about treatment options, and showed increases in knowledge of side effects of radiation therapy.ConclusionThe plain language DA presenting medical evidence in text and numerical formats appears acceptable and useful in decision-making about localized prostate cancer treatment. Further testing should evaluate the impact of all three media on decisions made and quality of life in the survivorship period, especially among very low literacy men.

This scoping review of the 2000-2015 literature on strategies for and approaches to expanding URM representation in medicine reveals a repetitive, amplifying message of URM physician service commitment to vulnerable populations in medically underserved communities. Such message repetition reinforces policies and practices that might limit the full scope of URM practice, research and leadership opportunities in medicine. Cross-nationally, service commitment and patient-physician concordance benefits admittedly respond to recognised societal need, yet there is an associated risk for instrumentally singling out members of URMs to fulfil that need. The proceedings of a 2001 US Institute of Medicine symposium warned against creating a deterministic expectation that URM physicians provide care to minority populations. Our findings suggest that the expanding emphasis on URM service commitment and patient-physician concordance benefits warrants ongoing scrutiny and, more broadly, represent a cautionary tale of unintended consequences for medical educators globally.

Recent guidelines on cancer screening have given not only more screening options but also conflicting recommendations. Thus, patients, with their clinicians’ support, must decide whether to get screened or not, which modality to use, and how often to get screened. Decision aids could potentially lead to better shared decision making regarding screening between the patient and the clinician. We reviewed 73 decision aids on screening for breast, cervical, colorectal, and prostate cancers. The goal of this review was to assess the effectiveness of such decision aids, examine areas in need for more research, and determine how the decision aids can be currently applied in the real world setting. Most studies used sound study design. Significant variation existed in setting, theoretical framework, and measured outcomes. Just over a third of the decision aids included an explicit values clarification. Other than knowledge, little consistency was noted in which patient attributes were measured as outcomes. Few studies actually measured shared decision making. Little information was available on the feasibility and outcomes of integrating decision aids into practice. We discuss the implications for future research, as well as what the clinicians can do now to incorporate decision aids into their practice.

Background/Method. Decision aids have not been widely tested in diverse audiences. The authors conducted interviews in a 2 2 race by education design with participants who were 50 years old (n = 188). The decision aid was a be Informed decision making by patients is the gold standard in health care, particularly for utility-sensitive decisions such as treatment for benign prostatic hyperplasia.1-3 Patient decision aids (DAs) using print, video, and Internet media are increasingly being developed to explicitly inform patients about treatment choices and to involve them in decision making. Since DAs have grown out of expected utility theory and technology assessment, little research has focused on DAs as communication media. DA evaluations have used knowledge as an outcome measure, implicitly recognizing the importance of their communication function. However, further investigation of their effectiveness as communication instruments is needed. In a recent report, "Speaking of Health: Assessing Health Communication Strategies for Diverse Populations," the Institute of Medicine (IOM) pointed to the research implications of health communication and behavior change research. 4 The insights are important for emerging research into the efficacy and effectiveness of decision aids. The IOM report indicates that diversity may influence the effectiveness of health communication. For example, a given health behavior change may be attitudinally driven in one population, normatively driven in another, and primarily under the influence of personal agency in a 3rd population. Furthermore, theories of communication and behavior change recognize that sources and channels that are perceived as credible by one population may be distrusted or not used by another. For DAs to be broadly applicable across the population, it is important to investigate potential influences of race/ethnicity* and education on *The term race has several controversial and unsettled connotations. We use the word in its common usage, recognizing its lack of biologic meaning but its importance as a social construct. the interpretation of information and acceptability of shared decision making. The IOM summary findings and recommendations indicate that few studies of communication interventions address their relative effectiveness across relevant diverse groups, and they found none that systematically compare various approaches to addressing diversity or compare those approaches with efforts that ignore diversity altogether. As part of a larger study, we investigated the effects of race and education on knowledge and readiness to make a treatment decision following use of a previously developed DA videotape program for benign prostatic hyperplasia (BPH). The program, produced by the Foundation for Informed Medical Decision Making (FIMDM), is already in wide use and respects diversity in subtle ways. Black and white men are included in the program in patient and professional roles, but the program is meant for a general audience. This preliminary investigation ...
