RESUMO
This article summarizes the top 20 research studies of 2023 identified as POEMs (patient-oriented evidence that matters) and the most highly rated guidelines. A large randomized controlled trial found that the time antihypertensive medications are taken has no effect on important outcomes. A fixed-dose approach to statin prescribing is not inferior to a treat-to-target strategy for management of lipid levels. Blood pressure measurements using 24-hour ambulatory monitoring are better than office measurements for predicting mortality. In patients 80 years and older with atrial fibrillation, direct oral anticoagulants have fewer harms than vitamin K antagonists and similar benefits. In people at high risk of cardiovascular disease, the Mediterranean and low-fat diets are the better options among seven dietary programs. An observational study of people with acute COVID-19 in the Omicron phase showed that nirmatrelvir/ritonavir was effective in reducing hospitalizations and death. The diagnosis of urinary tract infection requires a higher optimal cutoff to define pyuria on automated microscopy than was thought. A new regimen has been found using one of the most effective treatments for toenail onychomycosis. Dextromethorphan, honey, and inhaled ipratropium do not appear to be effective for acute cough. Serotonin-norepinephrine reuptake inhibitors are effective for some types of pain syndromes. In a 6-week trial, adults with acute, nonspecific low back or neck pain treated with opioids had similar pain relief as those treated with placebo. In patients with knee osteoarthritis who want to participate in sports and recreation, 70 to 90 minutes of exercise produces better results than 20 to 30 minutes three times per week. Healthy behaviors are associated with a lower risk of developing type 2 diabetes mellitus. In patients 50 years and older with type 2 diabetes, cumulative glycemic control with A1C levels of greater than 9% is associated with an increased risk of dementia. Sodium-glucose cotransporter-2 inhibitors and glucagon-like peptide-1 receptor agonists are best for improving patient-oriented outcomes for type 2 diabetes. Mindfulness-based stress reduction is not inferior to escitalopram in adults with anxiety disorders. Framing depression as an adaptation to current circumstances can lead to better patient outcomes. People labeled as having a penicillin allergy can complete an amoxicillin oral provocation challenge in the primary care office and, following a negative result, have this label removed. A 5-year surveillance interval can be safely reconsidered in many older patients with colon polyps. Nonprescription hearing aids can be effective without a fitting by an audiologist. We wrap this up with the top guidelines of the year as determined by POEM readers.

Context: Patients over the age of 65 years are more likely to experience higher severity and mortality rates than other populations from COVID-19. Clinicians need assistance in supporting their decisions regarding the management of these patients. Artificial Intelligence (AI) can help with this regard. However, the lack of explainability-defined as "the ability to understand and evaluate the internal mechanism of the algorithm/computational process in human terms"-of AI is one of the major challenges to its application in health care. We know little about application of explainable AI (XAI) in health care. Objective: In this study, we aimed to evaluate the feasibility of the development of explainable machine learning models to predict COVID-19 severity among older adults. Design: Quantitative machine learning methods. Setting: Long-term care facilities within the province of Quebec. Participants: Patients 65 years and older presented to the hospitals who had a positive polymerase chain reaction test for COVID-19. Intervention: We used XAI-specific methods (e.g., EBM), machine learning methods (i.e., random forest, deep forest, and XGBoost), as well as explainable approaches such as LIME, SHAP, PIMP, and anchor with the mentioned machine learning methods. Outcome measures: Classification accuracy and area under the receiver operating characteristic curve (AUC). Results: The age distribution of the patients (n=986, 54.6% male) was 84.5â¡19.5 years. The best-performing models (and their performance) were as follows. Deep forest using XAI agnostic methods LIME (97.36% AUC, 91.65 ACC), Anchor (97.36% AUC, 91.65 ACC), and PIMP (96.93% AUC, 91.65 ACC). We found alignment with the identified reasoning of our models' predictions and clinical studies' findings-about the correlation of different variables such as diabetes and dementia, and the severity of COVID-19 in this population. Conclusions: The use of explainable machine learning models, to predict the severity of COVID-19 among older adults is feasible. We obtained a high-performance level as well as explainability in the prediction of COVID-19 severity in this population. Further studies are required to integrate these models into a decision support system to facilitate the management of diseases such as COVID-19 for (primary) health care providers and evaluate their usability among them.

BACKGROUND: Fragility fractures are a major health concern for older adults and can result in disability, admission to hospital and long-term care, and reduced quality of life. This Canadian Task Force on Preventive Health Care (task force) guideline provides evidence-based recommendations on screening to prevent fragility fractures in community-dwelling individuals aged 40 years and older who are not currently on preventive pharmacotherapy. METHODS: We commissioned systematic reviews on benefits and harms of screening, predictive accuracy of risk assessment tools, patient acceptability and benefits of treatment. We analyzed treatment harms via a rapid overview of reviews. We further examined patient values and preferences via focus groups and engaged stakeholders at key points throughout the project. We used the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approach to determine the certainty of evidence for each outcome and strength of recommendations, and adhered to Appraisal of Guidelines for Research and Evaluation (AGREE), Guidelines International Network and Guidance for Reporting Involvement of Patients and the Public (GRIPP-2) reporting guidance. RECOMMENDATIONS: We recommend "risk assessment-first" screening for prevention of fragility fractures in females aged 65 years and older, with initial application of the Canadian clinical Fracture Risk Assessment Tool (FRAX) without bone mineral density (BMD). The FRAX result should be used to facilitate shared decision-making about the possible benefits and harms of preventive pharmacotherapy. After this discussion, if preventive pharmacotherapy is being considered, clinicians should request BMD measurement using dual-energy x-ray absorptiometry (DXA) of the femoral neck, and re-estimate fracture risk by adding the BMD T-score into FRAX (conditional recommendation, low-certainty evidence). We recommend against screening females aged 40-64 years and males aged 40 years and older (strong recommendation, very low-certainty evidence). These recommendations apply to community-dwelling individuals who are not currently on pharmacotherapy to prevent fragility fractures. INTERPRETATION: Risk assessment-first screening for females aged 65 years and older facilitates shared decision-making and allows patients to consider preventive pharmacotherapy within their individual risk context (before BMD). Recommendations against screening males and younger females emphasize the importance of good clinical practice, where clinicians are alert to changes in health that may indicate the patient has experienced or is at higher risk of fragility fracture.

This article summarizes the top 20 research studies of 2022 identified as POEMs (patient-oriented evidence that matters), excluding COVID-19. Statins for primary prevention of cardiovascular disease produce only a small absolute reduction in a person's likelihood of dying (0.6%), having a myocardial infarction (0.7%), or having a stroke (0.3%) over three to six years. Supplemental vitamin D does not reduce the risk of a fragility fracture, even in people with low baseline vitamin D levels or a previous fracture. Selective serotonin reuptake inhibitors are preferred medical therapy for panic disorder, and patients who discontinue antidepressants are more likely to relapse (number needed to harm = 6) compared with those who continue. Combination therapy using a selective serotonin reuptake inhibitor, serotonin-norepinephrine reuptake inhibitor, or tricyclic antidepressant with mirtazapine or trazodone is more effective than monotherapy for first-line treatment of acute severe depression and when monotherapy fails. Using hypnotic agents for insomnia in adults comes with a significant trade-off between effectiveness and tolerability. In patients with moderate to severe asthma, using a combination of albuterol and glucocorticoid inhalers as rescue therapy reduces exacerbations and need for systemic steroids. Observational research shows an increased risk of gastric cancer in patients taking proton pump inhibitors (number needed to harm = 1,191 over 10 years). The American College of Gastroenterology updated its guideline for gastroesophageal reflux disease, and a new guideline provides sound advice for the evaluation and management of irritable bowel syndrome. Adults older than 60 years with prediabetes are more likely to become normoglycemic than to develop diabetes mellitus or die. Treatment of prediabetes via intensive lifestyle intervention or metformin has no impact on long-term cardiovascular outcomes. Persons with painful diabetic peripheral neuropathy have similar degrees of improvement with monotherapy using amitriptyline, duloxetine, or pregabalin and greater improvement with combination therapy. When communicating with patients about disease risk, most patients prefer numbers over words because people overestimate word-based probabilities. In terms of drug therapy, the duration of an initial varenicline prescription should be 12 weeks. Many drugs can interact with cannabidiol. No important difference was found among ibuprofen, ketorolac, and diclofenac for treatment of acute nonradicular low back pain in adults.

In our previous studies, we offered older family medicine patients testing for obstructive sleep apnea (OSA) and discovered that 80% of patients who accepted, were later diagnosed with unsuspected OSA. In the present study, we followed such patients for 3 years of usual treatment. The goals were to (1) observe whether wider testing for OSA would increase case recognition and treatment uptake; (2) identify symptom and health characteristics associated with diagnosis and treatment efficacy. 101 women and 75 men (>45 years) recruited from family medicine clinics completed questionnaires, polysomnography and consented to chart review (Time 1). Participants with OSA were offered treatment and follow-up with a sleep medicine specialist. All were re-evaluated after 3 years (Time 2). At Time 1, 93% of participants received a diagnosis of OSA. Of these, 53 initiated treatment (46 PAP therapy); at Time 2, 24 PAP users met criteria for adherence. PAP-adherent participants had worse OSA and worse reported symptoms at Time 1 than non-adherent participants. At Time 2, PAP-adherent participants improved on insomnia and daytime symptoms compared to non-adherent participants who showed no change. Adherent and non-adherent participants showed no difference in health indices at Time 1 and no change at three-year follow-up. Benefits of treatment included improvements in co-morbid insomnia and daytime functioning; however, offering wider testing for OSA to older, family medicine patients yielded a high rate of diagnosis but low treatment adoption and adherence. Therefore, a cost-effective strategy would identify and support those likely to adopt and adhere to treatment.

AIMS: The effect of tramadol on the cardiovascular system is largely unknown. There is concern that, with its multimodal mechanism of action to increase serotonin and norepinephrine levels in the body, it could increase the risk of arterial ischaemia and cardiovascular events. We aimed to compare the short-term risk of cardiovascular events with the use of tramadol to that of codeine among patients with non-cancer pain. METHODS: We conducted a retrospective population-based cohort study using data from the Clinical Practice Research Datalink (CPRD) with new users of tramadol or codeine from April 1998 to March 2017. Exposure was defined using an approach analogous to an intention-to-treat, with a maximum follow-up of 30 days. The primary endpoint was myocardial infarction, and secondary endpoints were unstable angina, ischaemic stroke, coronary revascularization, cardiovascular death and all-cause mortality. Hazard ratios (HRs) were estimated using Cox proportional hazards models, adjusted for high-dimensional propensity score. RESULTS: The final cohort included 123 394 tramadol users and 914 333 codeine users. When tramadol was compared to codeine, the adjusted hazard ratio (HR) of myocardial infarction was 1.00 (95% CI 0.81-1.24). There was also no evidence of elevated risks of unstable angina (0.92; 95% CI 0.67-1.27), ischaemic stroke (0.98; 95% CI 0.82-1.17), coronary revascularization (0.97; 95% CI 0.69-1.38), cardiovascular death (1.07; 95% CI 0.93-1.23) or all-cause mortality (1.03; 95% CI 0.94-1.14) when tramadol was compared to codeine. CONCLUSIONS: Short-term use of tramadol, compared with codeine, was not associated with an increased risk of cardiac events among patients with non-cancer pain.

Context: Use of trustworthy online consumer health information (OCHI) is generally associated with benefits, yet barriers such as low health literacy may reduce these benefits. One of the largest groups of OCHI consumers is parents of young children. In addition to OCHI, parents reach out to their social circle for tailored advice, emotional support, and culturally relevant parenting information. However, little is known, about the use of parenting OCHI by the parents' social circle. Objective: To uncover OCHI outcomes when members of parents' social circle search for OCHI. Study Design: Convergent mixed methods study. Setting: Online parenting and child health information newsletter and magazine, available at naitreetgrandir.com (N&G). Population studied: Participants who completed a questionnaire about the information presented by N&G between April 13th, 2019 to March 30th, 2021. Instrument: The validated Information Assessment Method (IAM) questionnaire, implemented by N&G since 2015. Main outcome measures: IAM responses on OCHI outcomes by participants were analyzed using descriptive statistics, and responses compared between parents and their entourage (grandparents, family, friends and neighbours). Qualitative component: 14 parents' entourage members were interviewed to uncover perceived OCHI outcomes (up to saturation) and thematic analysis was conducted. Quantitative and qualitative components were conducted and analysed separately; results were compared using a joint display to provide a complete picture. Results: 51,320 completed IAM questionnaires (81% by parents) were included in the analysis, pertaining to 1079 N&G webpages (mean 47.6; range 1-637). Entourage members were more likely than parents to report using the information in a discussion with someone else and this led them to being better able to make a decision with those persons. Interviewees described sharing the information they found in some situations or not sharing it to avoid conflict. They used the information to provide support or do something for the parent(s) or child. Sharing information led to improved decision making, improved relationships, less worry and better health outcomes, or in some cases led to tensions. Conclusion: By better understanding how people use information together, health information can be adapted to meet both individual and group needs. Public health interventions aimed at supporting parents can do so by facilitating shared decision making.
RESUMO
BACKGROUND: Evidence-Based Medicine is built on the premise that clinicians can be more confident when their decisions are grounded in high-quality evidence. Furthermore, evidence from studies involving patient-oriented outcomes is preferred when making decisions about tests or treatments. Ideally, the findings of relevant and valid trials should be stable over time, that is, unlikely to be reversed in subsequent research. OBJECTIVE: To evaluate the stability of evidence from trials relevant to primary healthcare and to identify study characteristics associated with their reversal. METHODS: We studied synopses of randomized controlled trials (RCTs) published from 2002 to 2005 as "Daily POEMs" (Patient Oriented Evidence that Matters). The initial evidence (E1) from these POEMs (2002-2005) was compared with the updated evidence (E2) on that same topic in a summary resource (DynaMed 2019). Two physician-raters independently categorized each POEM-RCT as (i) reversed when E1 ≠ E2, or as (ii) not reversed, when E1 = E2. For all "Evidence Reversals" (E1 ≠ E2), we assessed the direction of change in the evidence. RESULTS: We evaluated 408 POEMs on RCTs. Of those, 35 (9%; 95% confidence interval [6-12]) were identified as reversed, 359 (88%) were identified as not reversed, and 14 (3%) were indeterminate. On average, this represents about 2 evidence reversals per annum for POEMs about RCTs. CONCLUSIONS: Over 12-17 years, 9% of RCTs summarized as POEMs are reversed. Information alerting services that apply strict criteria for relevance and validity of clinical information are likely to identify RCTs whose findings are stable over time.
We studied the extent to which evidence from randomized controlled trials (RCTs) relevant to primary care is contradicted in subsequent research. When it was, we identified this event as an evidence reversal. In addition, we sought to identify characteristics of RCTs associated with their reversal. From 408 RCTs published during the period 20022005, study characteristics such as sample size were identified and extracted. Subsequently, we compared the evidence reported in each of these RCTs with the evidence on that same topic in an online summary resource in 2019. This allowed us to classify each RCT in one of the following 3 categories: evidence confirmed, reversed, or uncertain if this evidence is confirmed or reversed. Over 1217 years of follow-up time, the findings of about 9 in 10 RCTs summarized as POEMs are stable. We found no statistically significant associations between trial characteristics and their subsequent reversal. This low rate of evidence reversal is good news for the RCTs that are used to inform decision-making.

This article summarizes the top 20 research studies of 2021 identified as POEMs (patient-oriented evidence that matters) that did not address the COVID-19 pandemic. Sodium-glucose cotransporter-2 inhibitors and glucagon-like peptide-1 receptor agonists prevent adverse cardiovascular and renal outcomes in patients with type 2 diabetes mellitus and also reduce all-cause and cardiovascular mortality. Most older adults (mean age, 75 years) with prediabetes do not progress to diabetes. Among patients in this age group with type 2 diabetes treated with medication, an A1C level of less than 7% is associated with increased risk of hospitalization for hypoglycemia, especially when using a sulfonylurea or insulin. For patients with chronic low back pain, exercise, nonsteroidal anti-inflammatory drugs, duloxetine, and opioids were shown to be more effective than control in achieving a 30% reduction in pain, but self-discontinuation of duloxetine and opioids was common. There is no clinically important difference between muscle relaxants and placebo in the treatment of nonspecific low back pain. In patients with chronic pain, low- to moderate-quality evidence supports exercise, yoga, massage, and mindfulness-based stress reduction. For acute musculoskeletal pain, acetaminophen, 1,000 mg, plus ibuprofen, 400 mg, without an opioid is a good option. Regarding screening for colorectal cancer, trial evidence supports performing fecal immunochemical testing every other year. For chronic constipation, evidence supports polyethylene glycol, senna, fiber supplements, magnesium-based products, and fruit-based products. The following abdominal symptoms carry a greater than 3% risk of cancer or inflammatory bowel disease: dysphagia or change in bowel habits in men; rectal bleeding in women; and abdominal pain, change in bowel habits, or dyspepsia in men and women older than 60 years. For secondary prevention in those with established arteriosclerotic cardiovascular disease, 81 mg of aspirin daily appears to be effective. The Framingham Risk Score and the Pooled Cohort Equations both overestimate the risk of cardiovascular events. Over 12 years, no association between egg consumption and cardiovascular events was demonstrated. Gabapentin, pregabalin, duloxetine, and venlafaxine provide clinically meaningful improvements in chronic neuropathic pain. In patients with moderate to severe depression, initial titration above the minimum starting dose of antidepressants in the first eight weeks of treatment is not more likely to increase response. In adults with iron deficiency anemia, adding vitamin C to oral iron has no effect. In children with pharyngitis, rhinosinusitis, acute bronchitis, or acute otitis media, providing education combined with a take-and-hold antibiotic prescription results in 1 in 4 of those children eventually taking an antibiotic.

OBJECTIVE: To identify factors associated with unplanned return visits to the emergency department (ED) among the population aged 75 years and older. Moreover, it aims to determine the association between patients' access to primary care and unplanned return visits. DESIGN: Data were collected from structured interviews, administrative databases, and medical charts at the index visits, and follow-up telephone calls were made at 3 months. SETTING: Emergency departments of the 3 tertiary care hospitals in Montréal, Que. PARTICIPANTS: Community-dwelling patients aged 75 years and older. MAIN OUTCOME MEASURES: Zero-inflated negative binomial regression analysis was conducted of unplanned return visits within 3 months. Rate ratios (RRs) and odds ratios (ORs) with 95% CIs are presented. RESULTS: During the study period, 4577 patients were identified, 2303 were recruited, and 1998 were retained for the analysis. Among the analysis sample, 33% were 85 and older, 34% lived alone, and 91% had a family physician. Before their ED visits, 16% of patients attempted to contact their family physicians. More than half of the patients reported having difficulty seeing their physicians for urgent problems, more than 40% had difficulty speaking with their family physicians by telephone, and more than one-third had difficulty booking appointments for new health problems. Within 3 months, 562 patients (28%) had made 894 return visits. Factors associated with a lower return visit rate included age 85 years and older (RR=0.80; 95% CI 0.67 to 0.96), less severe triage score (RR=0.83; 95% CI 0.74 to 0.92), and hospitalization at the index visit (RR=0.76; 95% CI 0.64 to 0.90). Factors that resulted in a higher return visit rate were difficulty booking appointments for new problems with their family physicians (RR=1.19; 95% CI 1.01 to 1.41), having had ED visits within the previous 6 months (RR=1.47; 95% CI 1.28 to 1.68), and higher Charlson comorbidity index scores (RR=1.06; 95% CI 1.01 to 1.11). Having had ED visits within the previous 6 months (OR=2.11; 95% CI 1.27 to 3.49), having a higher Charlson comorbidity index score (OR=1.41; 95% CI 1.19 to 1.68), and having received community care services (OR=3.00; 95% CI 0.95 to 9.53) also increased the odds of return visits. CONCLUSION: Although most people 75 years and older have a family physician, problems still exist in terms of timely access. Unplanned return visits to the ED are associated with having more comorbidities, having had previous ED visits, having already received community services, and having difficulty booking appointments with family physicians for new problems.

Spaced education is a learning strategy to improve knowledge acquisition and retention. To date, no robust evidence exists to support the utility of spaced education in the Family Medicine residency. We aimed to test whether alerts to encourage spaced education can improve clinical knowledge as measured by scores on the Canadian Family Medicine certification examination. METHOD: We conducted a cluster randomized controlled trial to empirically and pragmatically test spaced education using two versions of the Family Medicine Study Guide mobile app. 12 residency training programs in Canada agreed to participate. At six intervention sites, we consented 335 of the 654 (51%) eligible residents. Residents in the intervention group were sent alerts through the app to encourage the answering of questions linked to clinical cases. At six control sites, 299 of 586 (51%) residents consented. Residents in the control group received the same app but with no alerts. Incidence rates of case completion between trial arms were compared using repeated measures analysis. We linked residents in both trial arms to their knowledge scores on the certification examination of the College of Family Physicians of Canada. RESULTS: Over 67 weeks, there was no statistically significant difference in the completion of clinical cases by participants. The difference in mean exam scores and the associated confidence interval did not exceed the pre-defined limit of 4 percentage points. CONCLUSION: Further research is recommended before deploying spaced educational interventions in the Family Medicine residency to improve knowledge.

This article summarizes the top 20 research studies of 2020 identified as POEMs (patient-oriented evidence that matters), including the two most highly rated guidelines of the year on gout and chronic obstructive pulmonary disease (COPD). Regarding COVID-19, handwashing and social distancing through stay-at-home orders or quarantine measures are effective at slowing the spread of illness. Use of proper face masks (not gaiters or bandanas) is also effective at preventing trans- mission. This is important because the virus can infect others during the presymptomatic phase. Aspirin can no longer be recommended for the primary prevention of cardiovascular disease. Human papillomavirus vaccination is strongly associated with reduced risk of invasive cervical cancer, especially in women who were vaccinated before 17 years of age. When a woman who is postmenopausal has a screening bone mineral density test, rechecking the test after three years does not help to identify those who will have a fragility fracture. A higher daily step count is associated with lower all-cause mortality. After one year of follow-up, physical therapy is preferred to glucocorticoid injections for osteoarthritis of the knee; acetaminophen is ineffective for acute low back pain or pain due to knee or hip osteoarthritis; and adding a muscle relaxant to ibuprofen does not improve functional outcomes or pain in people reporting moderate to severe back pain one week after starting treatment. Although short-term antibiotics and steroids are effective in treating acute exacerbations of COPD, not much else is. Successful communication with patients seeking an antibiotic for a flulike illness can be achieved with combinations of messaging, including information on antibiotic resistance and the self-limiting nature of the illness. A new prediction rule effectively identifies patients with a history of penicillin allergy who have a low likelihood of positive findings on allergy testing. Low-value screening tests in asymptomatic, low-risk patients often lead to further testing, diagnostic procedures, or referrals. A new tool helps determine the amount of change needed to signify a real difference between two laboratory values in the same person over time. Finally, a pillar of our specialty, continuity of care, is associated with decreased all-cause mortality.

Electronic cigarette (e-cigarette) use has risen to unprecedented levels among youth in the United States. In this review, we discuss the patterns of use underlying the current youth vaping epidemic, potential harms from e-cigarette use, and the regulatory, public health, and clinical responses to e-cigarette use among youth. Between 2017 and 2018, past 30-day use of nicotine e-cigarettes among high school seniors nearly doubled, from 11% to 21%, representing the largest recorded increase for any adolescent substance use in over four decades. There are concerns that e-cigarette use could renormalize smoking behaviors, lead to the uptake of conventional cigarette use by youth, and have adverse effects in the developing brain and lungs of adolescents. Prevention and harm reduction efforts thus far have focused on policies to prevent youth access to vaping products and on public health strategies to expose the risks of youth vaping. However, it remains unclear if ongoing initiatives are sufficient to curb e-cigarette use by youth. Most health professionals agree that youth exposure to e-cigarettes needs to be addressed but feel uninformed, rely on unconventional information sources such as the media and their patients, and report that routine screening procedures concerning e-cigarettes are lacking. A coordinated effort from policy makers, public health agencies, parents, educators, health practitioners, and researchers is essential to mitigate harms from e-cigarette use in this vulnerable population.
RESUMO
BACKGROUND: Typically, web-based consumer health information is considered more beneficial for people with high levels of education and income. No evidence shows that equity-oriented information offers equal benefits to all. This is important for parents of low socioeconomic status (SES; low levels of education and income and usually a low level of literacy). OBJECTIVE: This study is based on a conceptual framework of information outcomes. In light of this, it aims to compare the perception of the outcomes of web-based parenting information in low-SES mothers with that of other mothers and explore the perspective of low-SES mothers on contextual factors and information needs and behavior associated with these outcomes. METHODS: A participatory mixed methods research was conducted in partnership with academic researchers and Naître et grandir (N&G) editors. N&G is a magazine, website, and newsletter that offers trustworthy parenting information on child development, education, health, and well-being in a format that is easy to read, listen, or watch. Quantitative component (QUAN) included a 3-year longitudinal observational web survey; participants were mothers of 0- to 8-year-old children. For each N&G newsletter, the participants' perception regarding the outcomes of specific N&G webpages was gathered using a content-validated Information Assessment Method (IAM) questionnaire. Differences between participants of low SES versus others were estimated. Qualitative component (QUAL) was interpretive; participants were low-SES mothers. The thematic analysis of interview transcripts identified participants' characteristics and different sources of information depending on information needs. Findings from the two components were integrated (QUAN+QUAL integration) through the conceptual framework and assimilated into the description of an ideal-typical mother of low SES (Kate). A narrative describes Kate's perception of the outcomes of web-based parenting information and her perspective on contextual factors, information needs, and behavior associated with these outcomes. RESULTS: QUAN-a total of 1889 participants completed 2447 IAM responses (50 from mothers of low SES and 2397 from other mothers). N&G information was more likely to help low-SES participants to better understand something, decrease worries, and increase self-confidence in decision making. QUAL-the 40 participants (21 N&G users and 19 nonusers) used 4 information sources in an iterative manner: websites, forums, relatives, and professionals. The integration of QUAN and QUAL findings provides a short narrative, Kate, which summarizes the main findings. CONCLUSIONS: This is the first study comparing perceptions of information outcomes in low-SES mothers with those of other mothers. Findings suggest that equity-oriented, web-based parenting information can offer equal benefits to all, including low-SES mothers. The short narrative, Kate, can be quickly read by decision policy makers, for example, web editors, and might encourage them to reach the underserved and provide and assess trustworthy web-based consumer health information in a format that is easy to read, listen, or watch.

In 2019, regular surveillance of 110 English-language research journals identified 254 studies that met the criteria to become POEMs (patient-oriented evidence that matters). Physician members of the Canadian Medical Association rated these POEMs for their relevance to patients in their practices. This article summarizes the clinical questions and bottom-line answers from the top 20 POEMs of 2019. Taking blood pressure medications at night results in a large mortality reduction over six years compared with morning dosing. Automated devices are the best way to measure blood pressure. Nonfasting lipid profiles are preferred over fasting lipid profiles, and nonfasting and fasting lipid profiles are equally effective at predicting risk. The benefit of statins for primary prevention in people 75 years and older is uncertain at best. Aspirin has no net benefit for primary prevention of cardiovascular disease and has no effect on cancer outcomes. An Italian study found fecal immunochemical testing over five biennial screening cycles has a similar colorectal cancer yield as screening colonoscopy, whereas a meta-analysis found that taking aspirin, an anticoagulant, or a nonsteroidal anti-inflammatory drug has no impact on the positive predictive value of fecal immunochemical testing. Regarding infections, a meta-analysis showed that patients presenting with symptoms of acute respiratory tract infection are unlikely to have pneumonia if vital signs and the lung examination findings are normal. For streptococcal pharyngitis (strep throat), penicillin V at a dosage of 800 mg four times a day for five days is at least as effective as a dosage of 1,000 mg three times a day for 10 days. A primary care study in the United Kingdom reinforced that clinicians should counsel parents of children with lower respiratory tract symptoms to be patient, because these infections can take three weeks or more to fully resolve. Among direct oral anticoagulants, apixaban has the lowest bleeding risk, and cotreating with a proton pump inhibitor significantly reduces bleeding risk. Single ibuprofen doses from 400 to 800 mg significantly reduce acute pain to a similar degree. The two-dose recombinant zoster vaccine is much more effective than the single-dose live, attenuated vaccine but with a greater risk of injection site pain. Exercise helps reduce the risk of falls in older adults. Practice guidelines from 2019 on antithrombotics for atrial fibrillation, the management of type 2 diabetes mellitus, and screening for breast cancer were judged to be especially relevant.

In this article, we discuss the POEMs (patient-oriented evidence that matters) of 2019 judged to be most consistent with the principles of Choosing Wisely, an international campaign to reduce unnecessary testing and treatments. We selected these POEMs through a crowdsourcing strategy of the daily POEMs information service for the Canadian Medical Association's physician members. We present recommendations from these top POEMs of primary research or meta-analysis that identify interventions to encourage or consider avoiding in practice. The recommendations cover musculoskeletal conditions (e.g., do not recommend platelet-rich plasma injections for rotator cuff disease or knee osteoarthritis), respiratory disease (e.g., in clinically stable patients with community-acquired pneumonia, antibiotics can be stopped after five days), screening or preventive care (e.g., patients who take their blood pressure at home or in a pharmacy should know what to do when they have an elevated reading), and miscellaneous topics (e.g., in healthy adults treated for dermatophyte infection, do not obtain baseline or follow-up alanine transaminase level, aspartate transaminase level, or complete blood count). These POEMs describe interventions whose benefits are not superior to other options, are sometimes more expensive, or put patients at increased risk of harm. Knowing more about these POEMs and their connection with the Choosing Wisely campaign will help clinicians and patients engage in conversations better informed by high-quality evidence.

In 2018, through regular surveillance of more than 110 English-language research journals, 255 research studies met the criteria to become POEMs (patient-oriented evidence that matters). Using a validated tool, physician members of the Canadian Medical Association rated these POEMs for their relevance to patients in their practices. This article summarizes the clinical questions and bottom-line answers from the top 20 POEMs of 2018, as determined by these physicians. The top POEMs summarize potentially practice-changing research on the importance of accurate blood pressure measurement, the unclear benefits of lower blood pressure targets for hypertension, the lack of evidence regarding treatment of cough, advantages of shorter over longer courses of antibiotics for several common infections, the value of increased fluid intake for preventing recurrent urinary tract infections, and the benefit of nitrofurantoin over fosfomycin for the treatment of urinary tract infection. Other conclusions include the lack of benefit of anticonvulsants for low back pain, the value of nonopioid pain management compared with opioids, the risk of anxiety recurrence when an antidepressant is discontinued, the value of exercise for reducing the risk of depression, and the increased risk of fractures with the use of Z-drug hypnotics. Regarding clinical preventive services, adherence is better with fecal immunochemical tests than with older guaiac-based fecal occult blood tests for colon cancer screening; statins showed no benefit for patients 75 years or older; aspirin showed no benefit for cardiovascular disease prevention; and exercise, vision assessment, and environmental assessments may reduce the risk of falls. Finally, we identify the top POEMs summarizing clinical practice guidelines from the American College of Physicians, American College of Cardiology/American Heart Association, and the U.S. Preventive Services Task Force.
RESUMO
In this article, we discuss the POEMs (patient-oriented evidence that matters) of 2018 judged to be most consistent with the principles of the Choosing Wisely campaign. We selected these POEMs through a crowdsourcing strategy of the daily POEMs information service for Canadian Medical Association's physician members. We present recommendations from these top POEMs of primary research or meta-analysis that identify interventions to consider avoiding in practice. The recommendations cover musculoskeletal conditions (e.g., avoid decompression surgery for treatment of subacromial shoulder pain), respiratory disease (in mild asthma, do not routinely prescribe a long-term daily inhaled steroid over the as-needed use of budesonide/formoterol), infections (e.g., in children with acute respiratory tract infection, do not routinely prescribe broad-spectrum antibiotics over narrow-spectrum antibiotics), and cardiovascular disease (e.g., avoid blanket testing of cardiac troponin in patients with a low pretest likelihood of myocardial infarction). These POEMs describe interventions whose benefits are not superior to other options, are sometimes more expensive, or put patients at increased risk of harm. Knowing more about these POEMs and their connection with the Choosing Wisely campaign will help clinicians and their patients engage in conversations better informed by high-quality evidence.
RESUMO
BACKGROUND: Shared decision making is associated with improved patient outcomes in radiation oncology. Our study aimed to capture how shared decision-making practices-namely, communicating potential harms and benefits and discussing what matters to patients-occur in usual care. METHODS: We invited a convenience sample of clinicians and patients in a radiation oncology clinic to participate in a mixed methods study. Prior to consultations, clinicians and patients completed self-administered questionnaires. We audio-recorded consultations and conducted qualitative content analysis. Patients completed a questionnaire immediately post-consultation about their recall and perceptions. RESULTS: 11 radiation oncologists, 4 residents, 14 nurses, and 40 patients (55% men; mean age 64, standard deviation or SD 9) participated. Patients had a variety of cancers; 30% had been referred for palliative radiotherapy. During consultations (mean length 45 min, SD 16), clinicians presented a median of 8 potential harms (interquartile range 6-11), using quantitative estimates 17% of the time. Patients recalled significantly fewer harms (median recall 2, interquartile range 0-3, t(38) = 9.3, p < .001). Better recall was associated with discussing potential harms with a nurse after seeing the physician (odds ratio 7.5, 95% confidence interval 1.3-67.0, p = .04.) Clinicians initiated 63% of discussions of harms and benefits while patients and families initiated 69% of discussions about values and preferences (Chi-squared(1) = 37.8, p < .001). 56% of patients reported their clinician asked what mattered to them. CONCLUSIONS: Radiation oncology clinics may wish to use interprofessional care and initiate more discussions about what matters to patients to heed Jain's (2014) reminder that, "a patient isn't a disease with a body attached but a life into which a disease has intruded."
