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: Vehicle-ramming attacks have become a common tactic for terror organizations worldwide. However, the medical implications of vehicle-ramming attacks remain unknown.

Objectives: To investigate the characteristics of vehicle-ramming attack incidents and casualties in order to assist in guiding the policy of medical organizations. 

Methods: In this study we included all vehicle-ramming attacks recorded in the Israel Defense Forces-Trauma Registry between 2015 and 2019. Records were screened using text mining of incident, casualty, and injury descriptions. The selected records were examined manually to ensure that they were vehicle-ramming attacks. Incident and casualty data were retrieved from the trauma registry.

Results: During the years 2015–2019, a total of 36 vehicle-ramming attacks with 113 casualties were documented in the trauma registry. The median number of casualties, urgent casualties, and fatalities per incident was 3 (interquartile range [IQR] 2–5), 1 (IQR 1–2), and 1 (IQR 1–1), respectively. Of the incidents, 15 (42%) had three or more casualties. The most prevelant day of the week was Friday with 9 incidents (25%). Within the day, 21 incidents (58%) occurred between the hours of 12:00 and 18:00. Commonly injured body regions were lower extremities (55%), head (28%), and upper extremities. Ten victims (9%) died before arriving at a hospital.

Conclusions: Vehicle-ramming attacks tend to have multiple casualties, be deadly, occur more often on Fridays and in the afternoon, and result mostly in injuries to the extremities and the head. These findings could guide policymaking to improve medical response to vehicle-ramming attacks.

Background: The Israeli Defense Forces-Medical Corps (IDF-MC) focuses on reducing preventable death by improving prehospital trauma care. High quality documentation of care can serve casualty care and to improve future care. Currently, paper casualty cards are used for documentation. Incomplete data acquisition and inadequate data handover are common. To resolve these deficits, the IDF-MC launched the BladeShield 101 project.

Objectives: To assess the quality of casualty care data acquired by comparing standard paper casualty cards with the BladeShield 101.

Methods: The BladeShield 101 system consists of three components: a patient unit that records vital signs and medical care provided, a medical sensor that transmits to the patient unit, and a ruggedized mobile device that allows providers to access and document information. We compared all trauma registries of casualties treated between September 2019 and June 2020.

Results: The system was applied during the study period on 24 patients. All data were transferred to the military trauma registry within one day, compared to 72% (141/194) with a paper casualty card (P < 0.01). Information regarding treatment time was available in 100% vs. 43% (P < 0.01) of cases and 98% vs. 67% (P < 0.01) of treatments provided were documented comparing BladeShield 101 with paper cards, respectively.

Conclusions: Using an autonomous system to record, view, deliver, and store casualty information may resolve most current information flow deficits. This solution will ultimately significantly improve individual patient care and systematic learning and development processes.

Background: Recent studies show a high risk of developing malignancy in patients with Fanconi anemia. The most common solid tumor in this condition is head and neck squamous cell carcinoma (HNSCC) and there is often uncertainty and about disease behavior as well as chemotherapy and radiation response.

Objectives: To describe and characterize HNSCC among Fanconi anemia patients on the Israeli Fanconi Registry

Methods: Our study population included patients in Israel's inherited bone marrow failure registry who were diagnosed with Fanconi anemia between1980 and 2016. Demographic, clinical, and laboratory data were collected from patient charts.

Results: From the collected data, HNSCC was confirmed in 6/111 (5.4%) Fanconi anemia patients; 1 (17%) had classic HNSCC risk factors of tobacco abuse and 4 (56%) had undergone primary surgery. The 3 (50%) receiving concurrent chemoradiotherapy had mild side effects, while half developed metachronous primary malignancy, and all developed > 2 primary malignancies. The overall median survival of the patients in our study was 14 (0.5–57) months.

Conclusions: Fanconi anemia patients have a very high risk of developing HNSCC. Proactive screening for malignancies is needed for the head and neck regions. We also found that chemoradiotherapy can be used safely in high-stage cancers.

Background: Changes accommodating requirements of religious authorities in Israel resulted in the Brain and Respiratory Death Determination Law (BRDDL), which came into effect in 2009. These included considering patient wishes regarding the brain respiratory death determination (BRDD), mandatory performance of apnea and ancillary testing, establishment of an accreditation committee, and accreditation required for physicians performing BRDD.

Objectives: To assess the impact of the legislation from 2010–2019.

Methods: Data collected included the number of formal BRDDs and accredited physicians. Obstacles to declaring brain death and interventions applied were identified.

Results: Obstacles included lack of trained physicians to perform BRDD and interpret ancillary test results, inability to perform apnea or ancillary testing, and non-approach to next-of-kin objecting to BRDD. Interventions included physician training courses, additional ancillary test options, and legal interpretation of patient wishes for non-determination of BRD. As a result, the number of non-determinations related to next-of-kin objecting decreased (26 in 2010 to 5 in 2019), inability to perform apnea or ancillary testing decreased (33 in 2010 to 2 in 2019), and number of physicians receiving accreditation increased (210 in 2010 to 456 in 2019). Last, the consent rate for organ donation increased from 49% to 60% in 2019.

Conclusions: The initial decrease in BRDDs has reversed, thus enabling more approaches for organ donation. The increased consent rate may reflect in part the support of the rabbinate and confidence of the general public that BRDD is performed and monitored according to strict criteria.

Background: National registries for acromegaly and population-based data make an important contribution to disease understanding and management. Data concerning the epidemiology of acromegaly in Israel is scanty.

Objectives: To evaluate the epidemiology of acromegaly in different industrial areas in northern Israel.

Methods: Data from adult patients diagnosed with acromegaly from 2000 to 2020, living in Haifa and the western Galilee District were collected using the electronic database and medical records from Clalit Health Services. The prevalence of acromegaly in three distinct areas and overall were reported. In addition, other epidemiological data including associated co-morbidities, pituitary tumor size, and treatment modalities were collected.

Results: We identified 77 patients with a confirmed diagnosis of acromegaly. The overall prevalence was 155 cases/10⁶ inhabitants without statistically significant differences between the three areas. The mean age at diagnosis was 50 ± 1.8 years and the male to female ratio was 1.1. Macroadenoma and microadenoma were identified in 44 (57%) and 25 (33%), respectively. The frequency rate of acromegaly-associated co-morbidities such as diabetes, hypertension, carpal tunnel syndrome, and osteoporosis was similar to previously reported studies. The mean body mass index (BMI) was 29 ± 5.6 kg/m² .Obesity, with a BMI ≥ of 30 kg/m², was found in 29 patients (38%). The majority of patients underwent transsphenoidal surgery 67 (87%). Normalized insulin-like growth factor 1 was reported in 64 (83%).

Conclusions: A high prevalence of acromegaly was found in northern Israel. The pituitary microadenoma frequency rate is the highest reported.

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: Over the past several years there has been a marked increase in the number of Israel Defense Forces (IDF) soldiers having hip arthroscopy based on magnetic resonance arthrography diagnosis of hip labral tears and/or impingement.

Objectives: To detail characteristics of soldiers who underwent hip arthroscopy and assess outcomes and rate of return to duty.

Methods: A retrospective chart review was conducted of all soldiers who underwent hip arthroscopy 2018 to 2020, and soldiers referred for hip arthroscopy during 2021. Demographic, medical, and military service data were collected from the computerized patient record.

Results: Our study comprised 117 soldiers (29% combatants, 24% females) who underwent hip arthroscopy, mean age 22 ± 3 years, range 18–42; 45% had physiotherapy before surgery; 31% were diagnosed during or within 3 months of having back pain and 20% had been referred for psychological assistance (not related to the hip pain); 15.4% had serious adverse events. The mean time to return to any duty (including clerical work) was 8.0 ± 0.6 months; 56% of the soldiers never returned to service and were discharged from the military. During the one-year follow-up, only 6% returned to their full pre-symptom activity.

Conclusions: The short-term results of IDF soldiers who underwent hip arthroscopy during the study period were much inferior to those reported among athletes. The lack of specificity of the diagnostic tools (history, examination, and imaging) used to determine whether surgery for hip pain is likely to be beneficial in this population may be contributing to over-diagnosis and over-treatment.

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: Data on how the coronavirus disease 2019 (COVID-19) affected consultations in ophthalmic departments are sparse.

Objectives: To examine the epidemiology of ophthalmic consultations in a large pediatric emergency medicine department (PED) during the first nationwide COVID-19 lockdown in Israel.

Methods: The database of a tertiary pediatric medical center was retrospectively reviewed for patients aged < 18 years who attended the PED from 17 March to 30 April 2020 (first COVID-19 lockdown) and the corresponding period in 2019. Background, clinical, and disease-related data were collected from the medical charts and compared between groups.

Results: The study included 757 PED visits. There were no significant differences in demographics between the groups. The 2020 period was characterized by a decrease in PED visits (by 52%), increase in arrivals during late afternoon and evening (P = 0.013), decrease in visits of older children (age 5–10 year), and proportional increase in younger children (age 1–5 years) (P = 0.011). The most common diagnoses overall and during each period was trauma followed by conjunctivitis and eyelid inflammation. The mechanisms of trauma differed (P = 0.002), with an increase in sharp trauma and decrease in blunt trauma in 2020 (P < 0.001 for both). In 2020, 95% of traumatic events occurred in the home compared to 54% in 2019 (P < 0.001).

Conclusions: Parents need to learn appropriate preventive and treatment measures to prevent serious and long-term ophthalmic injury while minimizing their exposure to the COVID-19. PEDs and ophthalmic pediatric clinics should consider increasing use of telemedicine and the availability of more senior physicians as consultants during such times.

Background: The reduced immune response of maintenance hemodialysis patients to coronavirus disease 2019 (COVID-19) vaccines is a major concern.

Objectives: To analyze the late (6 months after full vaccination) antibody response and compare it to early post-vaccination titer.

Methods: We conducted a multicenter prospective study of 13 hemodialysis units in Israel.

Results: We demonstrated that the low titers observed among ESRD patients 2–3 months after vaccination with the Comirnaty vaccine (median 63.8 AU/ml) declined to critically lower values 6 months after full vaccination. (Mediananti S antibodies, 31 AU/ml). Seropositivity significantly declined among hemodialysis patients from 89% to 74% (P < 0.0001), although it did not significantly change among controls.

Conclusions: We recommend all patients on hemodialysis receive a booster COVID-19 vaccine 6 months after the second dose.

Background: Secondary immune thrombocytopenic purpura (ITP) associated with coronavirus disease 2019 (COVID-19) is a rare but serious complication of the pandemic. Diagnostic criteria include clinical and laboratory findings. Early treatment is often effective, but rare severe bleeding and death can occur. An autoimmune mechanism is likely.

Objectives: To determine a role for molecular mimicry in producing disease.

Methods: Hexapeptide and heptapeptide matches between severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and platelet N-glycosylated proteins and other human proteins were assessed.

Results: Shared viral and platelet glycoprotein peptides were found. Copy frequency of these peptides in the human proteome was low for many of the candidate molecular mimics.

Conclusions: The data support a contribution of molecular mimicry in COVID-19 ITP autoimmunity and offer avenues for in vitro diagnostic assay development. The continuation of the pandemic necessitates additional understanding of COVID-19 ITP as well as studies on diagnosis and mitigation.
