Towards a 21st century health care system: advancing the case for telecare

Abstract Telecare is increasingly recognized as an essential tool for a contemporary twenty-first century health care system even though the evidence is still emerging on its effectiveness. The need to find delivery models like telecare that improve both the convenience and value of care is universal, but particularly pressing for countries like the U.S. and Israel who are facing rising costs related to the needs of individuals with multiple complex conditions. This commentary provides highlights of the current state of practice and policy for telecare and the challenges that remain ahead as it is adopted into the mainstream

Drug-Resistant Salmonella typhi in Pakistan

Enteric fever (formerly typhoid fever) is a bacterial illness caused by fecal-oral transmission of Salmonella typhi or paratyphi. In early 2018, an outbreak of Salmonella typhi resistant to third-generation cephalosporins, ampicillin, ciprofloxacin, trimethroprim-sulfamethoxazole, and chloramphenicol was reported in Pakistan. This strain, termed "extensively resistant typhi," has infected more than 5000 patients in endemic areas of South Asia, as well as travelers to and from these areas, including 5 cases in the United States. We present the case of one such child who developed extensively resistant enteric fever during a recent visit to Pakistan and required broader antimicrobial treatment than typically required. Clinicians should be aware that incoming cases of enteric fever may be nonsusceptible to commonly recommended antibiotics and that extensively resistant typhi requires treatment with carbapenems such as meropenem or azithromycin

Machine Learning-Augmented Propensity Score-Adjusted Multilevel Mixed Effects Panel Analysis of Hands-On Cooking and Nutrition Education versus Traditional Curriculum for Medical Students as Preventive Cardiology: Multisite Cohort Study of 3,248 Trainees over 5 Years

Background. Cardiovascular disease (CVD) annually claims more lives and costs more dollars than any other disease globally amid widening health disparities, despite the known significant reductions in this burden by low cost dietary changes. The world’s first medical school-based teaching kitchen therefore launched CHOP-Medical Students as the largest known multisite cohort study of hands-on cooking and nutrition education versus traditional curriculum for medical students. Methods. This analysis provides a novel integration of artificial intelligence-based machine learning (ML) with causal inference statistics. 43 ML automated algorithms were tested, with the top performer compared to triply robust propensity score-adjusted multilevel mixed effects regression panel analysis of longitudinal data. Inverse-variance weighted fixed effects meta-analysis pooled the individual estimates for competencies. Results. 3,248 unique medical trainees met study criteria from 20 medical schools nationally from August 1, 2012, to June 26, 2017, generating 4,026 completed validated surveys. ML analysis produced similar results to the causal inference statistics based on root mean squared error and accuracy. Hands-on cooking and nutrition education compared to traditional medical school curriculum significantly improved student competencies (OR 2.14, 95% CI 2.00–2.28, p<0.001) and MedDiet adherence (OR 1.40, 95% CI 1.07–1.84, p=0.015), while reducing trainees’ soft drink consumption (OR 0.56, 95% CI 0.37–0.85, p=0.007). Overall improved competencies were demonstrated from the initial study site through the scale-up of the intervention to 10 sites nationally (p<0.001). Discussion. This study provides the first machine learning-augmented causal inference analysis of a multisite cohort showing hands-on cooking and nutrition education for medical trainees improves their competencies counseling patients on nutrition, while improving students’ own diets. This study suggests that the public health and medical sectors can unite population health management and precision medicine for a sustainable model of next-generation health systems providing effective, equitable, accessible care beginning with reversing the CVD epidemic
