JBI systematic review protocol of text/opinions on how to best collect race-based data in healthcare contexts.

INTRODUCTION: Racialized population groups have worse health outcomes across the world compared with non-racialized populations. Evidence suggests that collecting race-based data should be done to mitigate racism as a barrier to health equity, and to amplify community voices, promote transparency, accountability, and shared governance of data. However, limited evidence exists on the best ways to collect race-based data in healthcare contexts. This systematic review aims to synthesize opinions and texts on the best practices for collecting race-based data in healthcare contexts. METHODS AND ANALYSES: We will use the Joanna Briggs Institute (JBI) method for synthesizing text and opinions. JBI is a global leader in evidence-based healthcare and provides guidelines for systematic reviews. The search strategy will locate both published and unpublished papers in English in CINAHL, Medline, PsycINFO, Scopus and Web of Science from 1 January 2013 to 1 January 2023, as well as unpublished studies and grey literature of relevant government and research websites using Google and ProQuest Dissertations and Theses. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement methodology for systematic reviews of text and opinion will be applied, including screening and appraisal of the evidence by two independent reviewers and data extraction using JBI's Narrative, Opinion, Text, Assessment, Review Instrument. This JBI systematic review of opinion and text will address gaps in knowledge about the best ways to collect race-based data in healthcare. Improvements in race-based data collection, may be related to structural policies that address racism in healthcare. Community participation may also be used to increase knowledge about collecting race-based data. ETHICS AND DISSEMINATION: The systematic review does not involve human subjects. Findings will be disseminated through a peer-reviewed publication in JBI evidence synthesis, conferences and media. PROSPERO REGISTRATION NUMBER: CRD42022368270.

Ethnic and national identity development processes: The role of cultural behaviors and gender.

Objective: This study examined the interrelations between Chinese and Canadian identity development during adolescence over an 18-month period using an individual-in-context perspective. We simultaneously considered the roles of youths' cultural behavior practices and their gender for predicting identity processes. We also examined whether practicing heritage cultural behaviors interferes with or is unrelated to national identity development and vice versa. Method: Adolescents with Chinese backgrounds (N = 152, 52% female; Mage = 14.95 years at Wave 1; SD = 1.70) were recruited from either a large metropolitan or midsized city in Canada. All parents were foreign-born, as were 80.2% of the adolescents. Results: Confirmatory factor analyses suggested that males and females reported a mostly stable sense of cultural identity and similar patterns of interrelation among identity belonging and exploration. There were two exceptions: Males did not report stability in Chinese identity belonging, and higher Canadian identity predicted increases in Chinese identity for males but decreases in Chinese identity for females. For both genders, more engagement in cultural behaviors predicted identity development within each cultural dimension and there were no associations across cultures. Conclusion: The data suggest that identity development in adolescence is fairly stable for Chinese Canadians. The evidence of gender differences in the interrelations of identity components underscores the value of considering multiple social identities. Finally, the finding that cultural behaviors support identity development within a culture and does not interfere with between-culture identity development suggests that providing opportunities to engage in heritage and national cultural behaviors can foster bicultural identity development.

A blind comparison of four non-invasive twelve-lead electrocardiogram algorithms for predicting susceptibility to ventricular tachycardia.

INTRODUCTION: To reduce QT measurement error, a new method was tested in which high-gain, high-speed, simultaneous 12-lead electrocardiographic (ECG) recordings were obtained during a single cardiac cycle. To increase its predictive power, the utility of combining QTD with the QRS duration for predicting susceptibility to ventricular tachyarrhythmia (VT) was analyzed. METHODS AND RESULTS: A total of 113 patients referred for electrophysiological study underwent baseline simultaneous 12-lead ECG followed by electrophysiological study to determine VT inducibility. Twenty-six patients had inducible VT while 87 patients did not. QT intervals and the width of QRS complex were measured from a single cardiac cycle with high-gain (8 times normal) and high-speed (100 mm/second) 12-lead ECG recordings. This method resulted in 100% QT interval identification throughout all 12 leads for every patient. Receiver-operator characteristic curves (ROC) and the areas under the ROC curves (AUC) were used to quantitatively analyze the performance of four ECG variables (QTD3, QTD12, QTD12 + QRS and QTD3 + QRS). All four ECG variables were significantly increased in the patients with inducible VT as compared to those without inducible VT. The QTD3 algorithm was less useful than QTD12 in predicting inducible VT; however, the addition of QRS duration to all QTD algorithms enhanced VT detection. CONCLUSION: 1) QRS duration has an incremental benefit in the detection of VT when combined with QTD; 2) QTD12 + QRS duration provided the highest predictive power among the four tested algorithms; 3) high-gain, high-speed 12-lead ECG recordings reduced QT measurement error.
