A machine learning model for colorectal liver metastasis post-hepatectomy prognostications.

Background: Currently, surgical resection is the mainstay for colorectal liver metastases (CRLM) management and the only potentially curative treatment modality. Prognostication tools can support patient selection for surgical resection to maximize therapeutic benefit. This study aimed to develop a survival prediction model using machine learning based on a multicenter patient sample in Hong Kong. Methods: Patients who underwent hepatectomy for CRLM between 1 January 2009 and 31 December 2018 in four hospitals in Hong Kong were included in the study. Survival analysis was performed using Cox proportional hazards (CPH). A stepwise selection on Cox multivariable models with Least Absolute Shrinkage and Selection Operator (LASSO) regression was applied to a multiply-imputed dataset to build a prediction model. The model was validated in the validation set, and its performance was compared with that of Fong Clinical Risk Score (CRS) using concordance index. Results: A total of 572 patients were included with a median follow-up of 3.6 years. The full models for overall survival (OS) and recurrence-free survival (RFS) consist of the same 8 established and novel variables, namely colorectal cancer nodal stage, CRLM neoadjuvant treatment, Charlson Comorbidity Score, pre-hepatectomy bilirubin and carcinoembryonic antigen (CEA) levels, CRLM largest tumor diameter, extrahepatic metastasis detected on positron emission-tomography (PET)-scan as well as KRAS status. Our CRLM Machine-learning Algorithm Prognostication model (CMAP) demonstrated better ability to predict OS (C-index =0.651), compared with the Fong CRS for 1-year (C-index =0.571) and 5-year OS (C-index =0.574). It also achieved a C-index of 0.651 for RFS. Conclusions: We present a promising machine learning algorithm to individualize prognostications for patients following resection of CRLM with good discriminative ability.

Observed Interactions, Challenges, and Opportunities in Student-Led, Web-Based Near-Peer Teaching for Medical Students: Interview Study Among Peer Learners and Peer Teachers.

BACKGROUND: Near-peer teaching (NPT) is becoming an increasingly popular pedagogical tool in health professions education. Despite the shift in formal medical education from face-to-face teaching toward encompassing web-based learning activities, NPT has not experienced a similar transition. Apart from the few reports on NPT programs hastily converted to web-based learning in light of the COVID-19 pandemic, no studies to date have explored web-based learning in the specific context of NPT. OBJECTIVE: This qualitative study examined the nature of interactions among peer learners (PLs), peer teachers (PTs), and the learning content in a student-led, web-based NPT program for medical students. METHODS: A 5-month-long voluntary NPT program to support first- and second-year medical students' biomedical science learning in the undergraduate medical curriculum was designed by 2 senior-year medical students and delivered by 25 PTs with 84 PLs participating. In total, 9 PLs and 3 PTs underwent individual semistructured interviews at the end of the program to explore general NPT experience, reasons for joining NPT, the effectiveness of NPT, the demand and importance of NPT, and the feasibility of incorporating NPT in the formal curriculum. Interview transcripts were analyzed using a thematic analysis approach. RESULTS: The first general theme focused on the nature of student-student, student-teacher, and student-content interactions. Although PLs were engaged in web-based NPT, there was minimal interaction between students, as most PLs preferred to learn passively and remain anonymous. PLs believed the web-based NPT learning process to be a unidirectional transmission of knowledge from teacher to learner, with the teacher responsible for driving the interactions. This was in sharp contrast to PTs' expectation that both parties shared responsibility for learning in a collaborative effort. The second general theme identified the advantages and disadvantages of delivering NPT on a web platform, which were mainly convenience and teaching skills development and poor interactivity, respectively. CONCLUSIONS: Student-led, web-based NPT offers a flexible and comfortable means of delivering academic and nonacademic guidance to medical students. However, the web-based mode of delivery presents unique challenges in facilitating meaningful interactions among PLs, PTs, and subject content. A blended learning approach may be best suited for this form of student-led NPT program to optimize its efficacy.

Exploring the Impact of Storytelling for Hospitalized Patients Recovering from COVID-19.

There are mental and physical deficits associated with COVID-19 infection, particularly among individuals requiring hospitalization. Storytelling is a relational intervention that has been used to help patients make sense of their illness experiences and to share their experiences with others, including other patients, families and healthcare providers. Relational interventions strive to create positive, healing stories versus negative ones. In one urban acute care hospital, an initiative called the Patient Stories Project (PSP) uses storytelling as a relational intervention to promote patient healing, including the development of healthier relationships among themselves, with families and with healthcare providers. This qualitative study employed a series of interview questions that were collaboratively developed with patient partners and COVID-19 survivors. The questions asked consenting COVID-19 survivors about why they chose to tell their stories and to flesh out more about their recovery process. Thematic analyses of six participant interviews resulted in the identification of key themes along a COVID-19 recovery pathway. Patients' stories revealed how survivors progress from being overwhelmed by their symptoms to making sense of what is happening to them, providing feedback to their care providers, feeling gratitude for care received, becoming aware of a new state of normal, regaining control of their lives, and ultimately discovering meaning and an important lesson behind their illness experience. Our study's findings suggest that the PSP storytelling approach holds potential as a relational intervention to support COVID-19 survivors along a recovery journey. This study also adds knowledge about survivors beyond the first few months of recovery.

Cross-sectional case-control study on medical students' psychosocial stress during COVID-19 pandemic in Hong Kong.

INTRODUCTION: COVID-19 pandemic has resulted in significant changes in pedagogy for undergraduate medical curriculum. Many physical clinical teachings have been replaced by online pedagogy. This study aims to evaluate the relation between medical students' stress during COVID-19 pandemic and their academic performance at the final examination. METHODS: This is a cross-sectional questionnaire-based study. Student's stress level were evaluated by the COVID-19 Student Stress Questionnaire (CSSQ). Correlation of stress level and students' performance at the final examination was performed. RESULTS: 110 out of 221 (49.8%) final-year medical students responded to the questionnaire, 13 students failed in the final examination (case) while 97 students passed in the final MBBS examination (control).Baseline demographic data between case and control were comparable. The median age for both cases and controls were 24 years.Compared to controls, cases reported higher levels of stress in all domains, namely in relation to risk of contagion, social isolation, interpersonal relationships with relatives, university colleagues and professors, academic life, and sexual life. Notably, a significantly higher proportion of cases reported academic-related stress compared to controls (p < 0.01), with 100% of cases perceiving their academic studying experience during the COVID-19 pandemic to be "very" or "extremely" stressful, compared to 35.1% of controls. CONCLUSION: Increased stress to academic and study during COVID-19 was associated with worse examination outcome at the final examination. Extra academic support will be needed to cater students' need during the pandemic.

Addressing Conflicts of Interest in Health and Medicine: Current Evidence and Implications for Patient Decision Aid Development.

BACKGROUND: More stringent policies for addressing conflicts of interest have been implemented around the world in recent years. Considering the value of revisiting conflict of interest quality standards set by the International Patient Decision Aid Standards (IPDAS) Collaboration, we sought to review evidence relevant to 2 questions: 1) What are the effects of different strategies for managing conflicts of interest? and 2) What are patients' perspectives on conflicts of interest? METHODS: We conducted a narrative review of English-language articles and abstracts from 2010 to 2019 that reported relevant quantitative or qualitative research. RESULTS: Of 1743 articles and 118 abstracts identified, 41 articles and 2 abstracts were included. Most evidence on the effects of conflict of interest management strategies pertained only to subsequent compliance with the management strategy. This evidence highlighted substantial noncompliance with prevailing requirements. Evidence on patient perspectives on conflicts of interest offered several insights, including the existence of diverse views on the acceptability of conflicts of interest, the salience of conflict of interest type and monetary value to patients, and the possibility that conflict of interest disclosure could have unintended effects. We identified no published research on the effects of IPDAS Collaboration conflict of interest quality standards on patient decision making or outcomes. LIMITATIONS: Because we did not conduct a systematic review, we may have missed some evidence relevant to our review questions. In addition, our team did not include patient partners. CONCLUSIONS: The findings of this review have implications for the management of conflicts of interest not only in patient decision aid development but also in clinical practice guideline development, health and medical research reporting, and health care delivery.

Developmental differences in the malleability of implicit racial bias following exposure to counterstereotypical exemplars.

Research suggests that exposure to stories about Black adults who are contributing positively to their community can reduce implicit pro-White/anti-Black racial bias in older children (ages 9-12). The aim of the current research was to replicate and extend this finding by investigating whether a different child-friendly manipulation exposing children to positive Black exemplars and negative White exemplars could decrease implicit pro-White/anti-Black racial bias in children aged 5 to 12 years, both immediately following the intervention and 1 hr later. In addition, a second aim of this research was to examine whether child-friendly positive exemplar exposure would similarly reduce adults' implicit racial bias. In a sample of White and Asian Canadians (N = 478; 182 male, 296 female), recruited from a community science center (children) and a public university in Vancouver (adults), 9- to 12-year-old children's racial bias was reduced up to 1 hr after this new intervention, while the effectiveness of the intervention on 5- to 8-year-old children's bias was less clear. Interestingly, this intervention did not reduce adult levels of bias. The results of a follow-up study (N = 96; 23 male, 72 female, 1 nonbinary) indicate that exposure to child exemplars can reduce bias in adults, but only when additional instructions are provided to internalize the presented association. Thus, the current study provides evidence that depicting counterstereotypical exemplars can reduce implicit racial bias in children for up to 1 hr after exemplar exposure, but there may be important developmental differences in the conditions required to change this bias.

Virtual Reality for Pediatric Needle Procedural Pain: Two Randomized Clinical Trials.

OBJECTIVE: To assess the efficacy and safety of a virtual reality distraction for needle pain in 2 common hospital settings: the emergency department (ED) and outpatient pathology (ie, outpatient laboratory). The control was standard of care (SOC) practice. STUDY DESIGN: In 2 clinical trials, we randomized children aged 4-11 years undergoing venous needle procedures to virtual reality or SOC at 2 tertiary Australian hospitals. In the first study, we enrolled children in the ED requiring intravenous cannulation or venipuncture. In the second, we enrolled children in outpatient pathology requiring venipuncture. In the ED, 64 children were assigned to virtual reality and 59 to SOC. In pathology, 63 children were assigned to virtual reality and 68 to SOC; 2 children withdrew assent in the SOC arm, leaving 66. The primary endpoint was change from baseline pain between virtual reality and SOC on child-rated Faces Pain Scale-Revised. RESULTS: In the ED, there was no change in pain from baseline with SOC, whereas virtual reality produced a significant reduction in pain (between-group difference, -1.78; 95% CI, -3.24 to -0.317; P = .018). In pathology, both groups experienced an increase in pain from baseline, but this was significantly less in the virtual reality group (between-group difference, -1.39; 95% CI, -2.68 to -0.11; P = .034). Across both studies, 10 participants experienced minor adverse events, equally distributed between virtual reality/SOC; none required pharmacotherapy. CONCLUSIONS: In children aged 4-11 years of age undergoing intravenous cannulation or venipuncture, virtual reality was efficacious in decreasing pain and was safe.

Clinical efficacy of virtual reality for acute procedural pain management: A systematic review and meta-analysis.

BACKGROUND: Acutely painful procedures are commonplace. Current approaches to pain most often involve pharmacotherapy, however, there is interest in virtual reality (VR) as a non-pharmacological alternative. A methodologically rigorous systematic review and meta-analysis is lacking. METHODS: Following PRISMA guidelines, we searched the Cochrane Library, Ovid MEDLINE, Embase, CINAHL, ERIC, NIHR Centre for Review and Dissemination, Proquest, the System for Information on Grey Literature in Europe and the WHO International Clinical Trials Registry Platform from inception to 5 November 2017. Included studies were randomised with an experimental trial design, included a non-VR control group and examined the efficacy of VR with regards to an acutely painful clinical intervention. Bias was assessed along Cochrane guidelines, with performance bias not assessed due to the non-blindable nature of VR. We extracted summary data for maximal pain score and used standard mean difference DerSimonian-Laird random-effects meta-analysis (RevMan 5.3). This review was prospectively registered (PROSPERO CRD42017058204). FINDINGS: Of the 12,450 studies identified, 20 studies were eligible for the systematic review. No trials reported in sufficient detail to judge their risk of bias, and 10 studies were at high risk of bias in at least one domain. 16 studies (9 randomised controlled trials, 7 crossover studies) examining 656 individuals were included in quantitative synthesis. Pain scales were heterogenous, but mostly employed 100-point scales. Across all trials, meta-analysis was suggestive of a -0.49 (95%CI -0.83 to -0.41, p = 0.006) standardised mean difference reduction in pain score with VR. However there was a high degree of statistical heterogeneity (χ2 p<0.001, I2 81%, 95%CI for I2 70-88%), driven by randomised studies, with substantial clinical heterogeneity. CONCLUSION: These data suggest that VR may have a role in acutely painful procedures, however included studies were clinically and statistically heterogenous. Further research is required to validate findings, establish cost efficacy and optimal clinical settings for usage. Future trials should report in accordance with established guidelines.

Emphasizing High Value, Cost-Effective Care in Physical Examination Instruction - A Qualitative Content Analysis of Interviews with Expert Educators.

This article was migrated. The article was marked as recommended. Introduction Physical examination and cost consciousness are critical competencies for medical trainees, but the intersection of these two skill domains is not described. We aimed to elucidate the role of physical examination in providing high value, cost conscious care (HVC) and to explore how clinical skills curricula could integrate principles of HVC. Methods We conducted a qualitative study of semi-structured interviews with 20 experts in the instruction and clinical applications of physical examination. We identified experts through purposeful sampling and snowball sampling. Audio-recorded interviews were coded using qualitative content analysis. Coded passages were categorized and reported as key themes and recommendations. Results Experts affirmed physical examination's indispensable role in clinical reasoning. When integrated with history-taking and additional diagnostic data, physical examination can further the aims of HVC. However, experts noted that the pace and demands of contemporary clinical practice present barriers to the idealized application of physical examination. In turn, participants discussed how to improve clinical skills curricula, both broadly and to promote HVC. Discussion To advance HVC through physical examination curricula, the clinical relevance of bedside skills needs to be emphasized across the training spectrum. Key strategies include revisiting evidence-based medicine principles and integrating physical examination instruction with teaching clinical reasoning.

Leveraging an electronic referral system to build a medical neighborhood.

BACKGROUND: Electronic referral and consultation systems are gaining popularity, but their contribution to the patient centered medical home-neighborhood framework of coordinated care delivery is not clear. We examined how specialists leverage an electronic referral and consultation system to deliver specialty care, identified determinants of high-quality electronic specialist communication and measured the impact of feedback to specialists on communication quality. METHODS: Referral patterns were identified for 19 specialties using eReferral in the San Francisco public health care delivery system. Primary care provider (PCP) ratings of the quality (helpfulness and educational value) of consultative communication were measured. Using logistic regression, we identified determinants of high-quality specialist communication during pre-consultative exchange or virtual co-management. Predictors included: specialty and reviewer type, referral volume, percent of referrals never scheduled and time spent by reviewers on eReferral. A pre-post analysis examined the impact of feedback on communication quality. RESULTS: The percentage of referrals immediately scheduled (27.2-82.8%) and never scheduled (7.7-59.3%) varied by specialty, with medical reviewers (vs. surgical and women׳s health) and physician reviewers (vs. nurse practitioners) scheduling fewer referrals immediately (p<0.001). Prevalence of high-quality communication was 71%, impacted by referral volume (adjusted odds ratio=0.78, 95%CI 0.68-0.88 for each additional 1000 referrals/year) and time spent per referral (1.18, 1.04-1.35 for each additional 3min). CONCLUSIONS: Specialists can use electronic referral and consultation systems to enhance specialty care delivery with consultative communication that is highly rated by PCPs. IMPLICATIONS: These data can inform the structure and functionality of future electronic consultation systems to maximize care coordination. LEVEL OF EVIDENCE: III.

School performance at age 7 years in late preterm and early term birth: a cohort study.

OBJECTIVE: To investigate the effect of gestational age, particularly late preterm birth (34-36 weeks gestation) and early term birth (37-38 weeks gestation) on school performance at age 7 years. DESIGN: Population-based prospective UK Millennium Cohort Study, consisting of linked educational data on 6031 children. METHODS: School performance was investigated using the statutory Key Stage 1 (KS1) teacher assessments performed in the third school year in England. The primary outcome was not achieving the expected level (≥level 2) of general performance in all three key subjects (reading, writing and mathematics). Other outcomes investigated subject-specific performance and high academic performance (level 3). RESULTS: 18% of full-term children performed below the expected KS1 general level, and risk of poor performance increased with prematurity: compared to children born at full-term, there was a statistically significant increased risk of poor performance in those born very preterm (<32 weeks gestation, adjusted RR 1.78, 95% CI 1.24 to 2.54), moderately preterm (32-33 weeks gestation, adjusted RR 1.71, 95% CI 1.15 to 2.54) and late preterm (34-36 weeks gestation, adjusted RR 1.36, 95% CI 1.09 to 1.68). Early term children performed statistically significantly worse in 4 out of 5 individual subject domains than full-term children, but not in the primary outcome (adjusted RR 1.07, 95% CI 0.94 to 1.23). CONCLUSIONS: Late preterm, and to a lesser extent, early term birth negatively impact on academic outcomes at 7 years as measured by KS1 assessments.

Zinc supplementation for preventing mortality, morbidity, and growth failure in children aged 6 months to 12 years of age.

BACKGROUND: Zinc deficiency is prevalent in low- and middle-income countries, and contributes to significant diarrhoea-, pneumonia-, and malaria-related morbidity and mortality among young children. Zinc deficiency also impairs growth. OBJECTIVES: To assess the effects of zinc supplementation for preventing mortality and morbidity, and for promoting growth, in children aged six months to 12 years of age. SEARCH METHODS: Between December 2012 and January 2013, we searched CENTRAL, MEDLINE, MEDLINE In-Process and Other Non-Indexed Citations, Embase, African Index Medicus, Conference Proceedings Citation Index, Dissertation Abstracts, Global Health, IndMED, LILACS, WHOLIS, metaRegister of Controlled Trials, and WHO ICTRP. SELECTION CRITERIA: Randomised controlled trials of preventive zinc supplementation in children aged six months to 12 years compared with no intervention, a placebo, or a waiting list control. We excluded hospitalised children and children with chronic diseases or conditions. We excluded food fortification or intake, sprinkles, and therapeutic interventions. DATA COLLECTION AND ANALYSIS: Two authors screened studies, extracted data, and assessed risk of bias. We contacted trial authors for missing information. MAIN RESULTS: We included 80 randomised controlled trials with 205,401 eligible participants. We did not consider that the evidence for the key analyses of morbidity and mortality outcomes were affected by risk of bias. The risk ratio (RR) for all-cause mortality was compatible with a reduction and a small increased risk of death with zinc supplementation (RR 0.95, 95% confidence interval (CI) 0.86 to 1.05, 14 studies, high-quality evidence), and also for cause-specific mortality due to diarrhoea (RR 0.95, 95% CI 0.69 to 1.31, four studies, moderate-quality evidence), lower respiratory tract infection (LRTI) (RR 0.86, 95% CI 0.64 to 1.15, three studies, moderate-quality evidence), or malaria (RR 0.90, 95% CI 0.77 to 1.06, two studies, moderate-quality evidence).Supplementation reduced diarrhoea morbidity, including the incidence of all-cause diarrhoea (RR 0.87, 95% CI 0.85 to 0.89, 26 studies, moderate-quality evidence), but the results for LRTI and malaria were imprecise: LRTI (RR 1, 95% CI 0.94 to 1.07, 12 studies, moderate-quality evidence); malaria (RR 1.05, 95% 0.95 to 1.15, four studies, moderate-quality evidence).There was moderate-quality evidence of a very small improvement in height with supplementation (standardised mean difference (SMD) -0.09, 95% CI -0.13 to -0.06; 50 studies), but the size of this effect might not be clinically important. There was a medium to large positive effect on zinc status.Supplementation was associated with an increase in the number of participants with at least one vomiting episode (RR 1.29, 95% CI 1.14 to 1.46, five studies, high-quality evidence). We found no clear evidence of benefit or harm of supplementation with regard to haemoglobin or iron status. Supplementation had a negative effect on copper status. AUTHORS' CONCLUSIONS: In our opinion, the benefits of preventive zinc supplementation outweigh the harms in areas where the risk of zinc deficiency is relatively high. Further research should determine optimal intervention characteristics such as supplement dose.

Physician behaviors to promote informed decisions for prostate cancer screening: a National Research Network study.

Clinical guidelines for prostate cancer screening (PCS) advise physicians to discuss the potential harms and benefits of screening. However, there is a lack of training programs for informed decision-making (IDM), and it is unknown which IDM behaviors physicians have the most difficulty performing. Identifying difficult behaviors can help tailor training programs. In the context of developing a physician-IDM program for PCS, we aimed to describe physicians' use of nine key IDM behaviors for the PCS discussion and to examine the relation between the behaviors and physician characteristics. A cross-sectional sample of The American Academy of Family Physicians National Research Network completed surveys about their behavior regarding PCS (N = 246; response rate = 58%). The surveys included nine physician key IDM behaviors for PCS and a single-item question describing their general practice style for PCS. The most common IDM behavior was to invite men to ask questions. The two least common reported behaviors concerned patients uncertain about screening (i.e., arrange follow-up and provide additional information for undecided men). Physicians reported difficulty with these two behaviors regardless whether they reported to discuss or not to discuss PCS with patients. Reported use of key IDM behaviors was associated with a general practice style for PCS and being affiliated with a residency-training program. Physician training programs for IDM should include physician skills to address the needs of patients uncertain about screening. Future research should determine if actual behavior is associated with self-reported behavior for the PCS discussion.

Disclosing conflicts of interest in patient decision aids.

BACKGROUND: In 2005, the International Patient Decisions Aid Standards (IPDAS) Collaboration developed quality criteria for patient decisions aids; one of the quality dimensions dealt with disclosure of conflicts of interest (COIs). The purposes of this paper are to review newer evidence on dealing with COI in the development of patient decision aids and to readdress the theoretical justification and definition for this quality dimension. METHODS: The committee conducted a primary systematic literature review to seek published research addressing the question, "What is the evidence that disclosure of COIs in patient decision aids reduces biased decision making?" A secondary literature review included a systematic search for recent meta-analyses addressing COIs in other spheres of health care, including research and publication, medical education, and clinical care. RESULTS: No direct evidence was found addressing this quality dimension in the primary literature review. The secondary review yielded a comprehensive Institute of Medicine report, as well as four relevant meta-analyses addressing disclosure of COIs in health care. They revealed a broad consensus that disclosure of COIs is desirable in such areas as research publication, guideline development, medical education, and clinical care. CONCLUSIONS: The committee recommends the criteria that are currently used to operationally define the quality dimension "disclosing conflicts of interest" be changed as follows (changes in italics): Does the patient decision aid: • report prominently and in plain language the source of funding to develop or exclusively distribute the patient decision aid? • report prominently and in plain language whether funders, authors, or their affiliations, stand to gain or lose by choices patients make after using the patient decision aid? Furthermore, based on a consensus that simple disclosure is insufficient to protect users from potentially biased information, the committee recommends that the IPDAS Collaboration consider adding the following criterion when the IPDAS consensus process is next conducted: "Does the patient decision aid: • report that no funding to develop or exclusively distribute the patient decision aid has been received from commercial, for-profit entities that sell tests or treatments included as options in the patient decision aid?"

A community-based intervention to promote informed decision making for prostate cancer screening among Hispanic American men changed knowledge and role preferences: a cluster RCT.

OBJECTIVE: We assessed the short-term effects of a community-based intervention for Hispanic men to encourage informed decision making (IDM) about prostate cancer screening with prostate specific antigen (PSA). METHODS: All senior social and housing centers in El Paso, TX were randomized to intervention, a group-based Spanish language educational program facilitated by promotores (12 centers; 161 men) [I's], or to control, promotores-facilitated diabetes video and discussion (13 centers; 160 men) [C's]. RESULTS: Participants had low levels of schooling and baseline knowledge; 44% reported previous PSA testing. At post-test, the I's made large knowledge gains, increased their understanding that experts disagree about testing, shifted toward more active decision making roles, were more likely to believe that it is important to weigh the advantages and disadvantages of screening and to anticipate potential screening outcomes in making a decision, and were less likely to consider the screening decision easy. The I's did not change in their screening intention or the belief that choosing not to be screened could be a responsible choice. CONCLUSIONS: A community-based intervention to support IDM for prostate cancer screening can increase knowledge and may promote more active involvement in decision making about prostate cancer screening. Such an approach can increase knowledge and may promote more active involvement in decision making about prostate cancer screening. PRACTICE IMPLICATIONS: It is feasible to develop and implement a community-based intervention program to promote IDM for prostate cancer screening.

A structured implicit abstraction method to evaluate whether content of counseling before prostate cancer screening is consistent with recommendations by experts.

OBJECTIVE: To assess the content of counseling about prostate-specific antigen (PSA) screening. Guidelines recommend informed consent before screening because of concerns about benefits versus risks. As part of the professional practice standard for informed consent, clinicians should include content customarily provided by experts. METHODS: 40 transcripts of conversations between medicine residents and standardized patients were abstracted using an instrument derived from an expert Delphi panel that ranked 10 "facts that experts believe men ought to know." RESULTS: Transcripts contained definite criteria for an average of 1.7 facts, and either definite or partial criteria for 5.1 facts. Second- and third-year residents presented more facts than interns (p=0.01). The most common facts were "false positive PSA tests can occur" and "use of the PSA test as a screening test is controversial." There was an r=0.88 correlation between inclusion by residents and the experts' ranking. CONCLUSION: Counseling varied but most transcripts included some expert-recommended facts. The absence of other facts could be a quality deficit or an effort to prioritize messages and lessen cognitive demands on the patient. PRACTICE IMPLICATIONS: Clinicians should adapt counseling for each patient, but our abstraction approach may help to assess the quality of informed consent over larger populations.

What is needed for informed decisions about prostate cancer screening: perspectives of African-American and Hispanic men.

Professional guidelines suggest that men should learn about risks and benefits of screening to make informed decisions consistent with their preferences. We used concept mapping to investigate views of informed decision making (IDM) of minority men. Statements about what men need for IDM about prostate cancer screening were sorted by similarity and rated for importance by 16 Hispanic and 15 African-American men. Multidimensional scaling and cluster analysis were used to develop a concept map for IDM. The 10-cluster solution was selected. The clusters rated most important were labeled Future Considerations, What to Know and Decision to Make. Clusters labeled Social Support and Sharing Perspectives depicted social aspects of the decision and were intermediate in importance. There was strong correlation in relative importance ratings of clusters by African-American and Hispanic men. However, African-American men gave higher importance ratings than Hispanic men. Concept mapping, a method with strong participatory elements, was useful in identifying conceptual frameworks for IDM of African-American and Hispanic men. Health education to support IDM requires some shifts in focus and strategy. It is important that interventions with minority men build upon a strong conceptual framework.
