Rates of Missed Injuries in the Prehospital Setting Are Unrelated to the Gender of the Medical Provider: A Retrospective Study.

BACKGROUND: Medical organizations worldwide aim for equity and diversity in the medical profession to improve care quality. Data on whether the caregiver gender affects outcomes in the prehospital setting are essential but scarce compared to available in-hospital studies. OBJECTIVES: To analyze the rates of missed injuries in the prehospital setting and determine whether these rates were associated with the gender of the on-field physician or paramedic. METHODS: A retrospective record review was conducted, which included trauma records documented in two trauma registries, the prehospital Israel Defense Forces-Trauma Registry (IDF-TR), and the in-hospital Israeli National Trauma Registry (INTR). Missed injuries were defined as injuries documented in the INTR but not in the IDF-TR. A multivariable regression analysis was performed to assess the association between provider's gender and missed injuries. RESULTS: Of 490 casualties, 369 (75.3%) were treated by teams that included only male paramedics or physicians. In 386 (78.8%) cases, a physician was a part of the prehospital team. In all, 94 (19.2%) casualties sustained injuries that were missed by the prehospital medical team. Missed injuries were not associated with the gender of the paramedic or physician (odds ratio 1.242, 95% confidence interval 0.69-2.193). CONCLUSIONS: No association was found between the gender of the medical provider in the prehospital setting and the rate of missed injuries. These results should encourage prehospital emergency medical systems to aim for a balanced and diverse caregiver population.

SARS-CoV-2 Epidemic in the Israeli Defense Force-Lessons Learned From Our rt-PCR Screening Policy.

BACKGROUND: During the SARS-CoV-2 pandemic, multiple preventative measures were used to prevent the virus from spreading in the population. The Israeli defense force deployed further means to contain the disease, including putting units in quarantine, physical distancing and using masks, gowns and disinfectants when in contact with suspected patients. METHODS: We used reverse transcriptase-polymerase chain reaction (rt-PCR) tests to screen for patients among asymptomatic soldiers within units participating in civilian aid or in close contact with known patients, using personal protective equipment. Positive results were repeated and followed with serological testing to verify the nature of results. RESULTS: Between April and May 2020, we screened a total of 1,453 soldiers in 13 different units. We found 11 false positive results, leading to unnecessary measures until resolution, and three true positive results (0.2%). All true positive results had unreported symptoms concomitant with SARS-CoV-2 disease. These results led to the resolution of this screening policy. CONCLUSION: Screening asymptomatic army personnel in this setting with rt-PCR test for SARS-CoV-2 is not warranted and leads to unnecessary false positive results. Efforts should be directed at identifying symptomatic patients.

SARS-CoV-2 Vaccine Acceptance Disparity Among Israeli Defense Forces Personnel.

INTRODUCTION: Promoting severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccine acceptance and uptake became necessary to achieve a high vaccination rate and subsequently herd immunity. Although the Israeli population has been largely acceptant of the SARS-CoV-2 vaccine, vaccine hesitancy has remained a major concern, especially in younger adults. We hypothesized that young adults who refused SARS-CoV-2 vaccination differed from those who have been adherent and could be characterized. Studying this specific population and recognizing individuals within this group who might be more probable to refuse vaccination can enable to target measures to further promote vaccination acceptance. METHODS: We conducted a cross-sectional comparison in a study population comprised of 17,435 Israeli Defense Forces (IDF) personnel who were SARS-CoV-2 vaccine eligible. This group included 14,834 vaccinated and 2,601 nonvaccinated individuals. Patient characteristics including occupational parameters, demographic features, psychotechnical grading (an intelligence assessment score), education level, and medical background were collected. RESULTS: The median age was 20.57 years and almost 80% were males. At the time of data collection, most individuals (85.1%, n = 14,834) have been vaccinated. Officers and noncommissioned officers were more likely to be vaccinated compared with regular soldiers (96%, and 90.2% vs. 83.3% respectively, P < .001), as well as combat battalions stationed personnel compared to their peers in rear and administrative units (89.4% vs. 78.4%, P < .001). Socioeconomic clusters were also associated with vaccination adherence, with 92.9% vs. 79.5% vaccination rates in the highest and lowest clusters, respectively (P < .001). Younger age, no previous immigration status, higher education level, and higher psychotechnical grades were also found associated with an increased likelihood of being vaccinated (P < .001). CONCLUSIONS: In a large cohort of enlisted IDF personnel, disparity in SARS-CoV-2 vaccine adherence was found to be related to multiple socioeconomic, educational, and military service-related variables. Although some differences were substantial, others were small and of questionable public health significance. Acknowledging these differences may enable community leaders, health care providers, and administrators to target specific populations in order to further promote SARS-CoV-2 vaccination acceptance.

Promoting Compliance to COVID-19 Vaccination in Military Units.

BACKGROUND: On December 27th, 2020, the Israeli Defense Forces initiated a mass COVID-19 vaccination campaign aiming to vaccinate its personnel. This population upheld specific characteristics in terms of age and sex, lack of significant comorbidities, and a general scarcity of risk factors for sustaining a severe COVID-19 illness. We present the measures taken to increase vaccination compliance, and the vaccination rate that followed these actions. Our secondary goal was to compare between vaccination rates in frontline battalions and highly essential military units (group A) and rear administration and support military units (group B). METHODS: This was a retrospective review that included 70 military units that were composed of 18,719 individuals of both sexes, mostly free of significant comorbidities. We divided the challenges of maximizing vaccination rates into two main categories: vaccine compliance (including communication and information) and logistical challenges. We compared the vaccination rates in groups A and B using a multivariable linear regression model. A P-value of .05 was considered significant. RESULTS: The mean age in 70 military units was 22.77 ± 1.35 (range 18-50) years, 71.13% males. A total of 726 (3.88%) individuals have been found positive for SARS-CoV-2 between March 1st, 2020 and February 18th, 2021. On February 18th, 2021, 54 days after the vaccination campaign was launched, 15,871 (84.79%) of the study population have been vaccinated by the first dose of Pfizer COVID-19 vaccine, expressing an 88.21% compliance rate (excluding recovered COVID-19 cases who were not prioritized to be vaccinated at this stage). Vaccination compliance in military units from group A was found to be higher when compared to group B (P < .001), leading to a 90.02% of group A population being either previously SARS-CoV-2 positive or COVID-19 vaccinated. CONCLUSIONS: A designated army campaign led by a multidisciplinary team could rapidly achieve a high COVID-19 vaccination rate. The information presented can serve organizations worldwide with similar characteristics that plan a mass COVID-19 vaccination campaign.

Measures to Limit COVID-19 Outbreak Effects Among Military Personnel: Preliminary Data.

INTRODUCTION: The COVID-19 outbreak posed a threat to the readiness of military forces as well as their ability to fulfill missions. Seeing that military forces have been encountering similar challenges, we found it eminent to share the Israeli Defense Force (IDF) Northern Command's (NC) preliminary experience. MATERIALS AND METHODS: We retrospectively summarized the actions that were taken by our team, focusing on 18 battalions at the Israeli NC. These actions included promoting a series of organizational changes in terms of social distancing and medical regulations as well as working to strengthen medical leadership through designated video meetings with medical commanders across our organization. Meetings included relevant clinical education, updates, and leadership building. These actions and others were aimed to increase our influence on the decision-making processes. While we conducted real-time reverse transcriptase polymerase chain reaction SARS-CoV-2 laboratory tests for soldiers who were suspected to have COVID-19 (those presenting with compatible signs and symptoms after having been exposed to a confirmed COVID-19 patient), we were not able to screen healthy populations, nor did we have serum antibody serologic tests available during the study period. We reviewed the COVID-19 outbreak national data, obtained from Ministry of Health publishings and the IDF databases. Data were included from February 26th, 2020 (day 0, first COVID-19 patient in Israel) to April 19th, 2020 (day 53, about 1 month after most of the COVID-19 regulation were issued in the NC). RESULTS: The mean age of the battalion soldiers was 21.29 ± 4.06 (range 18-50), 81.34% male. Most restrictions were issued on day 18. On day 53, 98.85% of the personnel in the battalions were kept active and asymptomatic in their units. CONCLUSIONS: Despite the limited availability of laboratory testing for COVID-19 our actions enabled us to lead a strict risk-management policy while maintaining most of the available workforce.

Ultra-short-term heart rate variability for early risk stratification following acute ST-elevation myocardial infarction.

OBJECTIVES: To evaluate the prognostic significance of early ultra-short-term heart rate variability (HRV) measurement in patients admitted for ST-elevation myocardial infarction (STEMI). METHODS: HRV was calculated retrospectively from the standard admission and discharge 10-second ECG of 196 consecutive patients with STEMI. Reduced HRV was defined as standard deviation of N-N intervals (SDNN) <9.5 (25th percentile). Data regarding all end points were obtained 2 years after discharge for all patients. RESULTS: Patients' age was 60.9 +/- 13 years and 21% were female. Admission SDNN was lower than discharge SDNN (20.2 +/- 18 vs. 34.2 +/- 31.1, respectively; p = 0.001). Admission and discharge SDNN positively correlated with survival (r = 0.16, p = 0.03 and r = 0.15, p = 0.04, respectively), but were not predictive of other cardiovascular end points. Reduced admission SDNN was associated with increased mortality at 1 and 6 months, and 1 and 2 years after admission, while discharge SDNN was associated only with 1- and 2-year mortality. Using multivariate analysis, adjusted for potential confounders, admission SDNN <9.5 was found to be an independent risk factor for 2-year mortality (odds ratio = 2.9, 95% confidence interval = 1.12-7.56; p = 0.028). CONCLUSIONS: Reduced HRV, recorded from admission and discharge ECG, appears to be a significant and independent predictor of all-cause mortality in patients with STEMI.

The Association Between Hospital Readmission and Pulmonologist Follow-up Visits in Patients With COPD.

BACKGROUND: The high frequency of readmissions in patients with COPD remains a significant problem. The impact of a pulmonologist follow-up visit during the month after discharge from hospital because of COPD exacerbation on reducing readmissions was examined. A profile of patients who did not attend the follow-up visits was built. METHODS: Our population-based retrospective cohort study analyzed the data of all patients with COPD who were treated at a lung institute in an Israeli hospital and were hospitalized between January 1, 2004, and December 31, 2010. Multivariate logistic regression was used to characterize the patient who did not attend the follow-up visit and to examine the effect of lack of visit on rehospitalization within 90 days of discharge. Cox proportional hazards analysis was used to model the effect of lacking visit on additional hospitalization or death during the study period. RESULTS: Of the 195 patients enrolled in the study, 44.1% had follow-up visits with pulmonologists within 30 days of discharge. Not attending the follow-up visit was associated with distant residence, a higher number of hospitalizations in the previous year, a lack of a recommendation in the discharge letter for a follow-up visit, and a lower frequency of follow-up visits with pulmonologists in the previous year. Moreover, not attending the follow-up visit was associated with a significant increased risk of rehospitalization within 90 days of discharge (OR, 2.91; 95% CI, 1.06-8.01). CONCLUSIONS: Early follow-up visits with pulmonologists seem to reduce the exacerbation-related rehospitalization rates of patients with COPD. We recommend that patients have early postdischarge follow-up visits with pulmonologists.

Mass casualty incident after the Taba terrorist attack: an organisational and medical challenge.

Two suicide bombings in and around Taba, Egypt, on 7 October 2004 created a complex medical and organisational situation. Since most victims were Israeli tourists, the National Emergency and Disaster Management Division handled their evacuation and treatment. This paper describes the event chronologically, as well as the organisational and management challenges confronted and applied solutions. Forty-nine emergency personnel and physicians were flown early to the disaster area to reinforce scarce local medical resources. Two hundred casualties were recorded: 32 dead and 168 injured. Eilat hospital was transformed into a triage facility. Thirty-two seriously injured patients were flown to two remote trauma centres in central Israel. Management of mass casualty incidents is difficult when local resources are inadequate. An effective response should include: rapid transportation of experienced trauma teams to the disaster zone; conversion of local medical amenities into a triage centre; and rapid evacuation of the seriously injured to higher level medical facilities.
