The aim of this study is to develop and validate a convolutional neural network (CNN)-based model for risk stratification of suspected NSTE-ACS patients and to compare its performance with currently available prehospital diagnostic tools.</p><p><strong>Methods: </strong>For this study, an internal training cohort and an external validation cohort were used, both consisting of suspected NSTE-ACS patients. A CNN (ECG interpretation by CNN (ECG-AI)) was trained and validated to detect NSTE-ACS.

However, restrictions on data sharing between secure data environments (SDEs) imposed limitations on the ability to carry out joint analyses across multiple separate datasets. There are currently significant efforts underway to enable such analyses using methods such as federated analytics (FA) and virtual SDEs. FA involves distributed data analysis without sharing raw data but does require sharing summary statistics. Virtual SDEs in principle allow researchers to access data across multiple SDEs, but in practice, data transfers may be restricted by information governance concerns.Secure multiparty computation (SMPC) is a cryptographic approach that allows multiple parties to perform joint analyses over private datasets with zero information sharing. SMPC may eliminate the need for data-sharing agreements and statistical disclosure control, offering a compelling alternative to FA and virtual SDEs. SMPC comes with a higher computational burden than traditional pooled analysis. However, efficient implementations of SMPC can enable a wide range of practical, secure analyses to be carried out.This perspective reviews the strengths and limitations of FA, virtual SDEs and SMPC as approaches to joint analyses across SDEs. We argue that while efforts to implement FA and virtual SDEs are ongoing in the UK, SMPC remains underexplored. Given its unique advantages, we propose that SMPC deserves greater attention as a transformative solution for enabling secure, cross-SDE analyses of private health data.</p>","PeriodicalId":9050,"journal":{"name":"BMJ Health & Care Informatics","volume":"32 1","pages":""},"PeriodicalIF":4.1,"publicationDate":"2025-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12107577/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144156818","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We determined the frequency of opioid analogue DAA overrides and assessed DAAs overridden by patient and provider type, the most common allergic reactions documented in electronic health records (EHR), reaction severity, and associated hypersensitivity.</p><p><strong>Methods: </strong>We conducted an observational cross-sectional study of DAAs in two geographically remote health systems. Patients were included if they were 18 years or older and had an opioid DAA generated when a medication was ordered. Patient and provider demographics, drug allergies, medication ordered, alert overrides, drug allergy reactions and DAA history were collected. Opioid analogue allergies were analysed by reaction type documented in the EHR, reaction severities (high, medium or low) and hypersensitivity reaction. Based on these factors, alerts were recommended to be interruptive requiring a coded response or changed to be non-interruptive (informational).</p><p><strong>Results: </strong>There were 700 493 alerts concerning opioid analogues fired for 50 527 patients across both sites, and 71.8% of these alerts were overridden. Nearly three-quarters of overridden reactions had a low to medium severity level at both institutions. Only 29.3% of the overridden alerts were truly immune-mediated.</p><p><strong>Discussion: </strong>Our recommendations would reduce interruptive alerts in half by converting them to non-interruptive alerts (46.4%). The data suggest opportunities to improve opioid-related CDS systems.</p><p><strong>Conclusions: </strong>We evaluated overrides of opioids and used this data to suggest ways to redesign DAAs to decrease alert override rates, combat alert fatigue and improve patient safety.</p>","PeriodicalId":9050,"journal":{"name":"BMJ Health & Care Informatics","volume":"32 1","pages":""},"PeriodicalIF":4.1,"publicationDate":"2025-05-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12104932/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144141342","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
