Background: The coronavirus disease 2019 (COVID-19) pandemic posed significant challenges to healthcare systems worldwide, including a surge in the use of extracorporeal membrane oxygenation (ECMO).

Objectives: To compare outcomes and costs of COVID-19 and non-COVID-19 adult patients treated with ECMO in the intensive care unit (ICU) at Tel Aviv Sourasky Medical Center.

Methods: We conducted a retrospective study. Clinical outcomes, ECMO duration, ICU and hospital length of stay (LOS), and healthcare costs were examined and compared between the two groups.

Results: A total of 119 patients were treated with ECMO between 2016 and 2023; 56 (47.1%) diagnosed with COVID-19. The study found no significant difference in mortality rates between COVID-19 and non-COVID-19 patients. However, COVID-19 patients experienced significantly longer ECMO durations and ICU LOS. Hospitalization and ECMO operation costs were notably higher for COVID-19 patients, but overall admission costs were lower compared to non-COVID-19 patients, with cost of surgical interventions, consultations and imaging contributing to the price gap.

Conclusions: Despite longer durations of ECMO and LOS, the economic burden of ECMO in COVID-19 patients was significantly lower than non-COVID-19 patients. Strict patient selection should be utilized, a fortiori during times of surge-capacity.

In this review, I described the development of the healthcare system in Theresienstadt during the Holocaust, from the establishment of the camp in late 1941 through 1945. Despite the horrific conditions, the Jews established a highly organized and relatively efficient system that was able to deliver excellent medical care to those eligible to receive care. The major factors that enabled development of the system included the heroic efforts of the high-level providers, the trust of patients, a public health approach to prevent epidemics and the perceived propaganda value of a good healthcare system to the Nazi oppressor. There were many challenges, particularly an informal triage policy that largely excluded medical care from the elderly (above age 60 years), mentally ill, and disabled. There were often difficult relations between caregivers related to ageism, gender, and national origin of the providers. Despite these adversities and the eventual futility due to the murder of the vast majority of the inhabitants, the Jews in Theresienstadt clung to life and tried their best to conduct a civilized society, in a large part through the delivery of excellent medical care.

Background: Advancements in artificial intelligence (AI) and natural language processing (NLP) have led to the development of language models such as ChatGPT. These models have the potential to transform healthcare and medical research. However, understanding their applications and limitations is essential.

Objectives: To present a view of ChatGPT research and to critically assess ChatGPT's role in medical writing and clinical environments.

Methods: We performed a literature review via the PubMed search engine from 20 November 2022, to 23 April 2023. The search terms included ChatGPT, OpenAI, and large language models. We included studies that focused on ChatGPT, explored its use or implications in medicine, and were original research articles. The selected studies were analyzed considering study design, NLP tasks, main findings, and limitations.

Results: Our study included 27 articles that examined ChatGPT's performance in various tasks and medical fields. These studies covered knowledge assessment, writing, and analysis tasks. While ChatGPT was found to be useful in tasks such as generating research ideas, aiding clinical reasoning, and streamlining workflows, limitations were also identified. These limitations included inaccuracies, inconsistencies, fictitious information, and limited knowledge, highlighting the need for further improvements.

Conclusions: The review underscores ChatGPT's potential in various medical applications. Yet, it also points to limitations that require careful human oversight and responsible use to improve patient care, education, and decision-making.

In the grand theater of modern medicine, artificial intelligence (AI) has swiped the lead role, with a performance so riveting it deserves an Oscar, or at least a Nobel. From the intricate labyrinths of our arteries to the profound depths of our peepers, AI is the new maestro, conducting symphonies of data with the finesse of a seasoned virtuoso [1,2].

A rise in the incidence of chronic health conditions, notably heart failure, is expected due to demographic shifts. Such an increase places an onerous burden on healthcare infrastructures, with recurring hospital admissions and heightened mortality rates being prominent factors. Efficient chronic disease management hinges on regular ambulatory care and preemptive action. The application of intelligent computational models is showing promise as a key resource in the ongoing management of chronic diseases, particularly in forecasting disease trajectory and informing timely interventions. In this review, we explored a pioneering intelligent computational model by Diagnostic Robotics, an Israeli start-up company. This model uses data sourced from insurance claims to forecast the progression of heart failure. The goal of the model is to identify individuals at increased risk for heart failure, thus enabling interventions to be initiated early, mitigating the risk of disease worsening, and relieving the pressure on healthcare facilities, which will result in economic efficiencies.

Background: Coronavirus disease 2019 (COVID-19) led to two nationwide lockdowns in Israel, reducing both supply and demand for medical services in the Israel Defense Force (IDF). IDF soldiers serve on bases within Israel, and most of them return home at the end of the day, similar to other armies in the world.

Objectives: To analyze the health services provided by the IDF with regard to policy changes during lockdowns.

Methods: We compared medical encounters between different services provided by the IDF Medical Corps. We related them to specific time periods: pre-first lockdown, first lockdown (and corresponding timeframes of the previous 3 years), between lockdowns, second lockdown, and post-second lockdown.

Results: Compared to past periods, we found a similar reduction of 27–30% in primary care medical encounter rates during the two lockdowns: 42–43% in sick days and 50–54% in referrals to the emergency department. Referral rates to all specialist medical encounters and elective surgeries decreased significantly during the first lockdown period and increased 1.2–3.5 times during the second lockdown.

Conclusions: A continuance of the shift to telehealth is required to withstand a future lockdown, with a full supply of secondary medical services attuned to core medical issues relevant for combat personnel. A liberal sick leave policy is required to eliminate unnecessary in-person visits, thus reducing the risk of infection.

Background: Lower extremity amputation related to diabetes is a serious outcome, which can have devastating effects on the patient and family. The epidemiology of amputations has recently been used as a possible measure of the adequacy of medical prevention and treatment of diabetes and diabetic foot complications.

Objectives: To report on patients undergoing amputations at one medical center in Israel, their co-morbidities, and the outcomes.

Methods: A retrospective chart study was conducted of amputees operated between 1 September 2017 and 30 September 2018.

Results: The study population comprised 72 patients who had major amputations for diabetes and/or ischemia, mean age 72 ± 10 years, 74% males, 93% with type 2 diabetes. Mean age corrected Charlson Comorbidity Index was 8.2 ± 2.1 with 90% (65 patients) presenting with a score of 6 or higher. Before the recent deterioration, fewer than 20% of the patients exited their home routinely and 24% had an official diagnosis of dementia. There were 31 below knee amputations (BKA) and 41 above knee amputations (AKA). The 30-day, 3-month, 1-year, and 2-year mortality rates were 15.3%, 27.8%, 43.1%, and 54.2% respectively. Median survival period was 20 months. Survival after AKA was 13.4 ± 20, which was significantly less than after BKA (25.4 ± 2.7, P = 0.097).

Conclusions: Factors other than the quality of management of patients with diabetes and complications may contribute to amputation rates; thus, making speculations from international comparisons of raw amputation rates problematic. This population was less healthy than reported in most studies.

Background: Environmental, social, and governance (ESG) is a form of international private business self-regulation that aims to contribute to society from a philanthropic, activist, or charitable nature by engaging in or supporting volunteering or ethically oriented practices. The major benefit of ESG is having the organization’s workers recruited for the goal of making the world a better place. There is a growing understanding regarding the extent of the environmental impacts of health services. Therefore, the interest in measuring and reporting the sustainability of health system performance is becoming crucial. As population aging and growth in healthcare demand are two of the main challenges of the current and mainly future health services, performance, and quality measurement as well as sustainability metrices are relevant more than ever.

Objectives: To review the ESG activities at Assuta Medical Centers (AMC) that helped the organization earn the Maala Index Platinum + grade in 2021.

Methods: We reviewed the ESG elements that were implemented at AMC.

Results: AMC entered an ESG process in November 2019 and earned Platinum and Platinum+ grades from the Maala Index in 2020 and 2021, respectively. AMC won the Workforce Diversity prize for having many employees over 60 years of age. AMC activities are detailed as a case study for other health organizations in Israel and worldwide.

Conclusions: A big leading health organization can spearhead sustainable development goals model in Israel and worldwide.

Background: Self-management, an active life routine, and adherence to physical activity are effective in the management of low back pain (LBP). However, delivering effective education and reassurance to patients can be a difficult for practitioners. The enhanced transtheoretical model intervention (ETMI) has shown to be successful and cost effective. The intervention focuses on educating practitioners to reassure patients, empower them to increase physical activity, and improve their self-efficacy.

Objectives: To assess whether ETMI can be implemented among primary care practitioners and to examine whether it reduces pain, disability, and fear avoidance as well as decreasing healthcare utilization. This protocol outlines the methodology for the implementation of ETMI through a hybrid implementation–effectiveness design.

Methods: Two qualitative and mixed-method studies provided a basis for an implementation prospective cohort study. Discussions are followed by a prospective cohort study with pre-and post-intervention measures as well as descriptions retrieving economic and therapeutic outcome data from the Maccabi Healthcare Services (MHS) databases. In addition, a fourth qualitative study was conducted at the midpoint of the implementation to evaluate the process by measuring the perceptions and practice of practitioners. The intervention group was 220 primary care practitioners and their patients (~n=10,000) from the central district of MHS. The control data was provided by other care districts with similar socioeconomic makeup (~n=40,000).

Conclusions: We evaluated the process and outcomes of the implementation of ETMI. We investigated the relationship between the care received (ETMI against treatment as usual) and healthcare utilization, costs, and patient-clinical outcomes.

Too much healthcare is prevalent, wasteful, and harmful. It consists of two separate phenomena: overdiagnosis and overuse. Overdiagnosis is the labeling of a person with a disease or abnormal condition that would not have caused the person harm if left undiscovered. Individuals derive no clinical benefit from overdiagnosis, although they may experience physical, psychological, or financial harm. It has been found that 15–30%, 20–50%, 0–67%, and 50–90% of people with screen detected breast, prostate, lung, and thyroid cancer, respectively, are overdiagnosed. Since many screening tests have trade-off between benefit and harm, a shared decision-making approach is essential. Incidental findings are very common and may also cause overdiagnosis. Overdiagnosis is recognizable in populations and not at the individual level. However, overuse is recognizable at the level of the individual practitioner. Choosing Wisely, an intervention directed at reducing low value care, now faces the challenge of developing interventions that go beyond recommendations. While some of the drivers of overdiagnosis and overuse are similar, different and parallel strategies are needed in order to reduce them. This is one of the major challenges to our health care system.

Overuse of healthcare services is a common phenomenon defined as: “a healthcare service that is provided under circumstances in which its potential for harm exceeds the possible benefit.” It is expressed in the gap between desired services and available ones and is accompanied by high financial and human life costs. One-fifth to one-third of patients receives unnecessary, ineffective, or potentially harmful treatments or services. One of the greatest challenges to understanding overuse is the lack of definition for appropriate use. Apart from the physical and mental damage caused by overuse or improper use of medical services, this phenomenon has many implications, such as increasing waiting times for services, creating long queues, and incurring considerable financial costs as over 10% of hospital expenses are used to correct medical errors or preventable infections. Government intervention through economic arrangements such as deductibles and pre-authorization of services by the insurer are partially effective in reducing the overuse of health services. Additional solutions include ensuring safety and quality of care as well as shared decision-making.

Background: On 18 March 2020, the Israeli Health Ministry issued lockdown orders to mitigate the spread of coronavirus disease 2019 (COVID-19).

Objectives: To assess the association of lockdown orders on telemedicine practice and the effect of social distancing on infectious diseases in a primary care community pediatric clinic as well as the rate of referrals to emergency departments (ED) and trends of hospitalization.

Methods: Investigators performed a retrospective secondary data analysis that screened for visits in a large pediatric center from 1 January to 31 May 2020. Total visits were compared from January to December 2020 during the same period in 2019. Visits were coded during the first lockdown as being via telemedicine or in-person, and whether they resulted in ED referral or hospitalization. Month-to-month comparisons were performed as well as percent change from the previous year.

Results: There was a sharp decline of in-person visits (24%) and an increase in telemedicine consultations (76%) during the first lockdown (p < 0.001). When the lockdown restrictions were eased, there was a rebound of 50% in-person visits (p < 0.05). There was a profound decrease of visits for common infectious diseases during the lockdown period. Substantial decreases were noted for overall visits, ED referrals, and hospitalizations in 2020 compared to 2019.

Conclusions: COVID-19 had a major impact on primary care clinics, resulting in fewer patient-doctor encounters, fewer overall visits, fewer ED referrals, and fewer hospitalizations

Background: Healthcare workers (HCWs) have close interaction with confirmed or suspected coronavirus disease 2019 (COVID-19) patients. Infection rates reported among HCWs is between 3% and 17%, and asymptomatic HCWs are a potential source of nosocomial transmission to vulnerable patients and colleagues. Universal mask use and good supply of personal protective equipment was implemented early at our institution.

Objectives: To determine the rate of infection by the serologic status of HCWs during first three COVID-19 waves, based on occupation and risk of exposure, compared to Israeli general population.

Methods: We conducted a prospective cohort study at Emek Medical Center from April 2020 to April 2021. A total of 101 HCWs volunteered to be followed at six time points by a serology test and a questionnaire.

Results: A total of 101 HCWs completed six serologic tests. All participants were seronegative at the four initial tests. The cumulative seropositivity rate for COVID-19 in HCWs was 9.9% (10/101). Only three seropositive HCWs (2.97%) were hospital-acquired.

Conclusions: Seroprevalence and seroconversion dynamics of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in 101 HCWs during COVID-19 outbreaks at Emek Medical Center were similar to the epidemiological curve of positive polymerase chain reaction results of the Israeli population, as published by the Israeli Ministry of Health, at each time point. Universal mask use and infection control measures may have contributed to a low hospital infection rate.
