While there has been much discussion relating to patients who left some sort of instructions, such as an advance directive, or have someone to speak on their behalf, less has been written on caring for patients who have nobody at all available to speak for them. It is thus crucial to develop clear and rigorous guidelines to properly care for these patients. The Jewish tradition offers an important perspective on caring for unrepresented patients and determining approaches to guide care providers. This article develops an understanding of fundamental Jewish principles that can provide clear guidance in navigating this challenge. It applies those values to a specific set of suggested behaviors, one of which adds a novel ritualized component to what has been recommended by bioethicists in the past.</p>","PeriodicalId":46408,"journal":{"name":"Rambam Maimonides Medical Journal","volume":"12 3","pages":""},"PeriodicalIF":1.5,"publicationDate":"2021-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8284992/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"39239726","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}

This research letter presents a cluster of severe medical conditions that were delayed in diagnosis due to postponed presentation to healthcare facilities during the COVID-19 pandemic. Ewing sarcoma, severe hemolytic anemia, endocarditis requiring surgery, and septic hip requiring surgery are some examples of cases we encountered with delayed diagnoses.
