RESUMO

INTRODUCTION: Early detection of melanoma requires timely access to medical care. In this study, we examined the feasibility of using artificial intelligence (AI) to flag possible melanomas in self-referred patients concerned that a skin lesion might be cancerous. METHODS: Patients were recruited for the study through advertisements in 2 hospitals in Halifax, Nova Scotia, Canada. Lesions of concern were initially examined by a trained medical student and if the study criteria were met, the lesions were then scanned using the FotoFinder System®. The images were analyzed using their proprietary computer software. Macroscopic and dermoscopic images were evaluated by 3 experienced dermatologists and a senior dermatology resident, all blinded to the AI results. Suspicious lesions identified by the AI or any of the 3 dermatologists were then excised. RESULTS: Seventeen confirmed malignancies were found, including 10 melanomas. Six melanomas were not flagged by the AI. These lesions showed ambiguous atypical melanocytic proliferations, and all were diagnostically challenging to the dermatologists and to the dermatopathologists. Eight malignancies were seen in patients with a family history of melanoma. The AI's ability to diagnose malignancy is not inferior to the dermatologists examining dermoscopic images. CONCLUSION: AI, used in this study, may serve as a practical skin cancer screening aid. While it does have technical and diagnostic limitations, its inclusion in a melanoma screening program, directed at those with a concern about a particular lesion would be valuable in providing timely access to the diagnosis of skin cancer.

RESUMO

BACKGROUND: There are increasing expectations for researchers and knowledge users in the health system to use a research partnership approach, such as integrated knowledge translation, to increase the relevance and use of research findings in health practice, programmes and policies. However, little is known about how health research trainees engage in research partnership approaches such as IKT. In response, the purpose of this scoping review was to map and characterize the evidence related to using an IKT or other research partnership approach from the perspective of health research trainees in thesis and/or postdoctoral work. METHODS: We conducted this scoping review following the Joanna Briggs Institute methodology and Arksey and O'Malley's framework. We searched the following databases in June 2020: MEDLINE, Embase, CINAHL and PsycINFO. We also searched sources of unpublished studies and grey literature. We reported our findings in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews. RESULTS: We included 74 records that described trainees' experiences using an IKT or other research partnership approach to health research. The majority of studies involved collaboration with knowledge users in the research question development, recruitment and data collection stages of the research process. Intersecting barriers to IKT or other research partnerships at the individual, interpersonal and organizational levels were reported, including lack of skills in partnership research, competing priorities and trainees' "outsider" status. We also identified studies that evaluated their IKT approach and reported impacts on partnership formation, such as valuing different perspectives, and enhanced relevance of research. CONCLUSION: Our review provides insights for trainees interested in IKT or other research partnership approaches and offers guidance on how to apply an IKT approach to their research. The review findings can serve as a basis for future reviews and primary research focused on IKT principles, strategies and evaluation. The findings can also inform IKT training efforts such as guideline development and academic programme development.

RESUMO

OBJECTIVE: The objective of this review was to determine the timing of overall and cause-specific neonatal mortality and severe morbidity during the postnatal period (1-28 days). INTRODUCTION: Despite significant focus on improving neonatal outcomes, many newborns continue to die or experience adverse health outcomes. While evidence on neonatal mortality and severe morbidity rates and causes are regularly updated, less is known on the specific timing of when they occur in the neonatal period. INCLUSION CRITERIA: This review considered studies that reported on neonatal mortality daily in the first week; weekly in the first month; or day 1, days 2-7, and days 8-28. It also considered studies that reported on timing of severe neonatal morbidity. Studies that reported solely on preterm or high-risk infants were excluded, as these infants require specialized care. Due to the available evidence, mixed samples were included (eg, both preterm and full-term infants), reflecting a neonatal population that may include both low-risk and high-risk infants. METHODS: MEDLINE, Embase, Web of Science, and CINAHL were searched for published studies on December 20, 2019, and updated on May 10, 2021. Critical appraisal was undertaken by 2 independent reviewers using standardized critical appraisal instruments from JBI. Quantitative data were extracted from included studies independently by 2 reviewers using a study-specific data extraction form. All conflicts were resolved through consensus or discussion with a third reviewer. Where possible, quantitative data were pooled in statistical meta-analysis. Where statistical pooling was not possible, findings were reported narratively. RESULTS: A total of 51 studies from 36 articles reported on relevant outcomes. Of the 48 studies that reported on timing of mortality, there were 6,760,731 live births and 47,551 neonatal deaths with timing known. Of the 34 studies that reported daily deaths in the first week, the highest proportion of deaths occurred on the first day (first 24 hours, 38.8%), followed by day 2 (24-48 hours, 12.3%). Considering weekly mortality within the first month (n = 16 studies), the first week had the highest mortality (71.7%). Based on data from 46 studies, the highest proportion of deaths occurred on day 1 (39.5%), followed closely by days 2-7 (36.8%), with the remainder occurring between days 8 and 28 (23.0%). In terms of causes, birth asphyxia accounted for the highest proportion of deaths on day 1 (68.1%), severe infection between days 2 and 7 (48.1%), and diarrhea between days 8 and 28 (62.7%). Due to heterogeneity, neonatal morbidity data were described narratively. The mean critical appraisal score of all studies was 84% (SD = 16%). CONCLUSION: Newborns experience high mortality throughout the entire postnatal period, with the highest mortality rate in the first week, particularly on the first day. Ensuring regular high-quality postnatal visits, particularly within the first week after birth, is paramount to reduce neonatal mortality and severe morbidity.

RESUMO

OBJECTIVE: The objective of this scoping review was to explore, characterize, and map the literature on interventions and intervention components implemented to change emergency department clinicians' behavior related to suicide prevention using the Behaviour Change Wheel as a guiding theoretical framework. INTRODUCTION: An emergency department is a critical place for suicide prevention, yet patients are often discharged without proper suicide risk assessments or referrals. In response, we must support emergency department clinicians' behavior change to follow evidence-based suicide prevention strategies. However, reviews to date have yet to systematically and theoretically examine the functional mechanisms of interventions and how these characteristics can influence emergency department clinicians' behaviors related to suicide prevention care. INCLUSION CRITERIA: This review considered interventions that targeted emergency department clinicians' behavior change related to suicide prevention. Behavior change referred to observable practice changes as well as proxy measures of behavior change, including changes in knowledge and attitude. METHODS: This review followed JBI methodology for scoping reviews. Searches included PubMed, PsycINFO, CINAHL, Embase, and gray literature, including targeted Google searches for relevant organizations/websites, ProQuest Dissertations and Theses Global, and Scopus conference papers (using a specific filter). This review did not apply any date limits, but our search was limited to the English language. Data extraction was undertaken using a charting table developed specifically for the review objective. Narrative descriptions of interventions were coded using the Behaviour Change Wheel's intervention functions. Reported outcome measures were categorized. Findings were tabulated and synthesized narratively. RESULTS: This review included a total of 70 sources, describing 66 different interventions. Forty-one studies were included from the database searches, representing a mixture of experimental (n = 2), quasi-experimental (n = 24), non-experimental (n = 12), qualitative (n = 1), and mixed methods (n = 2) approaches. An additional 29 citations were included from gray literature searches. One was a pilot mixed methods study, and the rest were interventions. Identified interventions comprised a wide range of Behaviour Change Wheel intervention functions to change clinicians' behavior: education (n = 48), training (n = 40), enablement (n = 36), persuasion (n = 21), environmental restructuring (n = 18), modeling (n = 7), and incentivization (n = 2). Based on the Behaviour Change Wheel analysis, many interventions targeted more than one determinant of behavior change, often employing education and training to improve clinicians' knowledge and skills simultaneously. Among the 42 studies that reported outcome measures, effectiveness was measured at clinician (n = 38), patient (n = 4), or organization levels (n = 6). Few studies reported implementation outcomes, such as measures of reach (n = 4), adoption (n = 5), or fidelity (n = 1). There were no evaluation data reported on the interventions identified through Google searches. CONCLUSIONS: Interventions included in this review were diverse and leveraged a range of mechanisms to change emergency department clinicians' behavior. However, most interventions relied solely on education and/or training to improve clinicians' knowledge and/or skills. Future research should consider diverse intervention functions to target both individual- and organization-level barriers for a given context. The ultimate goal for changing emergency department clinicians' behavior is to improve patient health outcomes related to suicide-related thoughts and behaviors; however, current research has most commonly evaluated clinicians' behavior in isolation of patient outcomes. Future studies should consider reporting patient-level outcomes alongside clinician-level outcomes.

RESUMO

OBJECTIVE: The objective of this review was to determine the timing of overall and cause-specific maternal mortality and severe morbidity during the postpartum period. INTRODUCTION: Many women continue to die or experience adverse health outcomes in the postpartum period; however, limited work has explored the timing of when women die or present complications during this period globally. INCLUSION CRITERIA: This review considered studies that reported on women after birth up to 6 weeks postpartum and included data on mortality and/or morbidity on the first day, days 2-7, and days 8-42. Studies that reported solely on high-risk women (eg, those with antenatal or intrapartum complications) were excluded, but mixed population samples were included (eg, low-risk and high-risk women). METHODS: MEDLINE, Embase, Web of Science, and CINAHL were searched for published studies on December 20, 2019, and searches were updated on May 11, 2021. Critical appraisal was undertaken by 2 independent reviewers using standardized critical appraisal instruments from JBI. Quantitative data were extracted from included studies independently by at least 2 reviewers using a study-specific data extraction form. Quantitative data were pooled, where possible. Identified studies were used to obtain the summary estimate (proportion) for each time point. Maternal mortality was calculated as the maternal deaths during a given period over the total number of maternal deaths known during the postpartum period. For cause-specific analysis, number of deaths due to a specific cause was the numerator, while the total number of women who died due to the same cause in that period was the denominator. Random effects models were run to pool incidence proportion for relative risk of overall maternal deaths. Subgroup analysis was conducted according to country income classification and by date (ie, data collection before or after 2010). Where statistical pooling was not possible, the findings were reported narratively. RESULTS: A total of 32 studies reported on maternal outcomes from 17 reports, all reporting on mixed populations. Most maternal deaths occurred on the first day (48.9%), with 24.5% of deaths occurring between days 2 and 7, and 24.9% occurring between days 8 and 42. Maternal mortality due to postpartum hemorrhage and embolism occurred predominantly on the first day (79.1% and 58.2%, respectively). Most deaths due to postpartum eclampsia and hypertensive disorders occurred within the first week (44.3% on day 1 and 37.1% on days 2-7). Most deaths due to infection occurred between days 8 and 42 (61.3%). Due to heterogeneity, maternal morbidity data are described narratively, with morbidity predominantly occurring within the first 2 weeks. The mean critical appraisal score across all included studies was 85.9% (standard deviation = 13.6%). CONCLUSION: Women experience mortality throughout the entire postpartum period, with the highest mortality rate on the first day. Access to high-quality care during the postpartum period, including enhanced frequency and quality of postpartum assessments during the first 42 days after birth, is essential to improving maternal outcomes and to continue reducing maternal mortality and morbidity worldwide.

RESUMO

OBJECTIVE: The objective of this scoping review is to identify and chart teaching strategies that educators use in classroom settings to engage diverse students in undergraduate nursing education programs. INTRODUCTION: Student engagement is critical to facilitating academic success and significant learning experiences for undergraduate nursing students. However, students from diverse backgrounds face challenges in undergraduate nursing programs, and these challenges impact their academic engagement and sense of belonging and inclusion. Creating conditions in nursing education that foster engagement by meeting the learning needs of diverse learners could facilitate their success, which ultimately might strengthen the nursing workforce diversity. INCLUSION CRITERIA: This review will consider papers on how educators engage undergraduate nursing students from diverse backgrounds in classroom settings, including online, face-to-face, and blended formats, irrespective of the country. Evidence obtained from all sources including qualitative, quantitative, and mixed methods studies, systematic reviews, as well as gray literature will be considered for inclusion. METHODS: JBI methodology for scoping reviews, which includes a three-step search strategy, will be employed. First, keywords will be identified from relevant articles in CINAHL and ERIC. Second, another search using the identified keywords and index terms across select databases will be conducted. Third, the reference lists of all identified articles will be screened for additional papers. Titles and abstracts will be screened by two independent reviewers, and then followed by the full text review of included articles against the inclusion criteria by two independent reviewers. Data will be extracted from included articles and the findings will be presented in tables, figures, and narratively as appropriate.
