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: Advanced heart failure (HF) carries a high rate of recurrent HF hospitalizations and a very high mortality rate. Mechanical devices and heart transplantation are limited to a select few. Dialysis may be a good alternative for advanced HF patients with volume overload despite maximal pharmacological therapy.

Objectives: To assess the net clinical outcome of peritoneal dialysis or hemodialysis in patients with advanced HF.

Methods: We analyzed all advanced HF patients who were referred for dialysis due to volume overload in our institution. Patients were followed for complications, HF hospitalizations, and survival.

Results: We assessed 35 patients; 10 (29%) underwent peritoneal dialysis and 25 (71%) underwent hemodialysis; 71% were male; median (interquartile range) age was 74 (67–78) years. Estimated glomerular filtration rate was 20 (13–32) ml/min per 1.73 m². New York Heart Association functional capacity was III. Median follow-up time was 719 days (interquartile range 658–780). One-year mortality rate was 8/35 (23%) and overall mortality rate was 16/35 (46%). Three patients (9%) died during the first year due to line or peritoneal dialysis related sepsis, and 6 (17%) died during the entire follow-up. The median number of HF hospitalizations was significantly reduced during the year on dialysis compared to the year prior to dialysis (0.0 [0.0–1.0] vs. 2.0 [0.0–3.0], P < 0.001).

Conclusions: Dialysis is reasonably safe and significantly reduced HF hospitalization in advanced HF patients. Dialysis could be a good alternative for advanced HF patients with intractable volume overload.

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.

Background: In response to the coronavirus disease-2019 (COVID-19) pandemic, routine clinical visits to the ophthalmic emergency department (OED) were deferred, while emergency cases continued to be seen.

Objectives: To assess the consequences of the COVID-19 pandemic for ophthalmic emergencies.

Methods: A retrospective chart analysis of patients who presented to the OED during the peak of the COVID-19 pandemic was conducted. The proportions of traumatic, non-traumatic-urgent, and non-traumatic-non-urgent presentations in 2020 were compared to those of the same time period in 2019. Duration of chief complains and best-corrected visual acuity were also assessed.

Results: There were 144 OED visits in 2020 compared to 327 OED visits during the same 3-week-period in 2019. Lower mean age of OED patients was present in 2020. Logarithmic expression (LogMAR) best corrected visual acuity (BVCA) was similar in both years. In 2020 there was a reduction in traumatic, non-traumatic-urgent, and non-traumatic-non-urgent cases compared to 2019 (15.4% reduction, P = 0.038; 57.6% reduction, P = 0.002; 74.6% reduction, P = 0.005, respectively). There was a higher proportion of same-day presentations at commencement of symptoms in 2020 compared with 2019 (52.8% vs. 38.8%, respectively P = 0.006).

Conclusions: During the COVID-19 pandemic, the number of OED visits at a tertiary hospital dropped by more than half. Although the drop in visits was mostly due to decrease in non-traumatic-non-urgent cases, there was also decrease in non-traumatic-urgent presentations with possible important visual consequences. Additional studies should elucidate what happened to these patients

Background: Potentially preventable readmissions of surgical oncology patients offer opportunities to improve quality of care. Identifying and subsequently addressing remediable causes of readmissions may improve patient-centered care.

Objectives: To identify factors associated with potentially preventable readmissions after index cancer operation.

Methods: The New York State hospital discharge database was used to identify patients undergoing common cancer operations via principal diagnosis and procedure codes between the years 2010 and 2014. The 30-day readmissions were identified and risk factors for potentially preventable readmissions were analyzed using competing risk analysis.

Results: A total of 53,740 cancer surgeries performed for the following tumor types were analyzed: colorectal (CRC) (42%), kidney (22%), liver (2%), lung (25%), ovary (4%), pancreas (4%), and uterine (1%). The 30-day readmission rate was 11.97%, 47% of which were identified as potentially preventable. The most common cause of potentially preventable readmissions was sepsis (48%). Pancreatic cancer had the highest overall readmission rate (22%) and CRC had the highest percentage of potentially preventable readmissions (51%, hazard ratio [HR] 1.42, 95% confidence interval [95%CI] 1.28–1.61). Risk factors associated with preventable readmissions included discharge disposition to a skilled nursing facility (HR 2.22, 95%CI 1.99–2.48) and the need for home healthcare (HR 1.61, 95%CI 1.48–1.75).

Conclusions: Almost half of the 30-day readmissions were potentially preventable and attributed to high rates of sepsis, surgical site infections, dehydration, and electrolyte disorders. These results can be further validated for identifying broad targets for improvement

Background: Hip fracture is common in elderly patients and is associated with high morbidity and mortality. Acute kidney injury (AKI) following hip fracture may have additional impact on clinical outcomes.

Objectives: To investigate the incidence of AKI, the risk factors for its occurrence and impact on mortality, timing of surgery, and length of hospitalization (LOS) in patients undergoing hip fracture surgery.

Methods: We retrospectively examined the records of patients who underwent hip fracture surgery between 2013 and 2017. All patients had a baseline serum creatinine value and at least one later value. AKI was defined according to KDIGO guidelines.

Results: The study included 511 patients. Mean age was 72.6 years, 325 males (63.4%); 151 (29.5%) had baseline eGFR < 60 ml/min/1.73m². Of these, 87 (17%) developed AKI. Older age, diabetes mellitus, hypertension, and chronic heart condition were significantly more common in patients who developed AKI. Patients with AKI had increased 30-day mortality (hazard ratio [HR] 3.96, 95% confidence interval [95%CI] 1.62–9.7, P = 0.003) and mortality at one year (HR 2.72, 95%CI 1.5–4.9, P = 0.002). AKI was associated with surgery delay > 48 hours (HR 2.241, 95%CI 1.206–4.165, P = 0.011). Mean LOS was 10.9 days and 8 days for patients with AKI and without, respectively, P < 0.0001.

Conclusions: AKI is a common complication in patients with hip fracture and is associated with increased short- and long-term mortality, delayed surgery, and longer hospitalization. Interventions identifying and monitoring patients at risk may contribute to improve the outcomes

Background: The recent increase in enterococcal urinary tract infections (EUTI) and the potential morbidity and mortality associated with inappropriate antimicrobial treatment underscores the need for early risk assessment and institution of appropriate empirical antimicrobial therapy.

Objectives: To identify high-risk features associated with hospitalized patients with EUTI.

Methods: Demographic, clinical, laboratory, and bacteriological data of 285 patients hospitalized with UTI during 2016 were retrieved from the computerized database of Shamir Medical Center. Patients were divided into two groups: EUTI and non-EUTI (NEUTI), according to the presence or absence of enterococcus in the urine culture. The features of the two groups were compared.

Results: We obtained 300 urine cultures from 285 patients. Of the total, 80 patients (26.6%) had EUTI and 220 patients (73.3%) had NEUTI. A higher prevalence of urinary multi-bacterial cultures was found in EUTI compared to NEUTI patients (P < 0.01). Higher prevalence of permanent indwelling urinary catheter and dementia were found in hospitalized patients with community-acquired EUTI and nosocomial EUTI respectively (P = 0.02, P = 0.016) compared to patients with NEUTI.

Conclusions: Indwelling urinary catheter and dementia are risk factors for EUTI in patients with community and hospital acquired infection, respectively

Background: Patients with severe coronavirus disease-2019 (COVID-19) are susceptible to superimposed infections.

Objectives: To describe COVID-19 patients who presented with complications due to Candida bloodstream co-infection (candidemia) and their outcome in a single center in northern Israel (Emek Medical Center) during the second outbreak of COVID-19 in Israel (15 June 2020 to 20 September 2020).

Methods: A retrospective study of COVID-19 patients presenting with candidemia was conducted, including clinical and laboratory data. The incidence of candidemia among hospitalized COVID-19 patients was compared to a historical cohort of non-COVID-19 controls.

Results: Three COVID-19 patients complicated with candidemia were documented. All three patients died shortly after the detection of candidemia. Three different Candida sp. were isolated from the blood cultures: C. albicans, C. parapsilosis, and C. glabrata. The incidence of candidemia among COVID-19 patients was 0.679 episodes per 1000 hospital days.

Conclusions: Our small sample suggests a much higher incidence of candidemia among COVID-19 patients compared to a historical cohort of non-COVID-19 controls. All clinicians treating COVID-19 patients in GICU should be aware of this complication

Background: Hip fractures in elderly patients are a major cause of morbidity and mortality. Variability in length of hospital stay (LOS) was evident in this population. The coronavirus disease-2019 (COVID-19) pandemic led to prompt discharge of effected patients in order to reduce contagion risk. LOS and discharge destination in COVID-19 negative patients has not been studied.

Objectives: To evaluate the LOS and discharge destination during the COVID-19 outbreak and compare it with a similar cohort in preceding years.

Methods: A retrospective study was conducted comparing a total of 182 consecutive fragility hip fracture patients operated on during the first COVID-19 outbreak to patients operated on in 2 preceding years. Data regarding demographic, co-morbidities, surgical management, hospitalization, as well as surgical and medical complications were retrieved from electronic charts.

Results: During the pandemic 67 fragility hip fracture patients were admitted (COVID group); 55 and 60 patients were admitted during the same time periods in 2017 and 2018, respectively (control groups). All groups were of similar age and gender. Patients in the COVID group had significantly shorter LOS (7.2 ± 3.3 vs. 8.9 ± 4.9 days, P = 0.008) and waiting time for a rehabilitation facility (7.2 ± 3.1 vs. 9.3 ± 4.9 days, P = 0.003), but greater prevalence of delirium (17.9% vs. 7% of patients, P = 0.028). In hospital mortality did not differ among groups.

Conclusions: LOS and time to rehabilitation were significantly shorter in the COVID group. Delirium was more common in this group, possibly due to negative effects of social distancing.

Background: The coronavirus disease-2019 (COVID-19) pandemic had enormous impact on many aspects of our society, including huge medical, social, and economic challenges.

Objective: To evaluate the impact of the first wave of the COVID-19 pandemic and the related movement restrictions on the incidence of hip fractures in different age groups.

Methods: This single center retrospective observational study included all patients over 60 years old admitted to our hospital with the diagnosis of hip fracture during March and April 2020. Exclusion criteria were periprosthetic or pathologic fractures and multitrauma. We collected the same data on all patients with hip fractures admitted during March and April of 2018 and 2019.

Results: Mean patient age increased from 81.7 to 85.0 years. Only two of 49 patients tested positive for COVID-19. The data show a decrease of 38% in fracture load, but a striking decrease of 85% and 59% among sexagenarians and septuagenarian, respectively. There was no decrease among nonagenarians. Early mortality, both at 30 days and 90 days, was twice as common during the pandemic. However, stratification by age group demonstrated that the risks of early mortality were the same as previous years. Mean waiting time for surgery decreased from 27.5 to 18.9 hours. Patient discharge to home over a rehabilitation facility increased from 9% to 17%.

Conclusions: The COVID-19 pandemic affected the epidemiology of hip fractures in the elderly. The incidence of fractures and age distribution were significantly different from other years. Discharge destinations were also affected. The management of hip fracture patients was not compromised.

Background: Decisions on medication treatment in children dying from cancer are often complex and may result in polypharmacy and increased medication burden. There is no information on medication burden in pediatric cancer patients at the end of life (EOL).

Objectives: To characterize medication burden during the last hospitalization in children dying from cancer

Methods: We performed a retrospective cohort study based on medical records of 90 children who died from cancer in hospital between 01 January 2010 and 30 December 2018. Demographic and clinical information were collected for the last hospitalization. We compared medication burden (number of medication orders) at hospitalization and at time of death and examined whether changes in medication burden were associated with clinical and demographic parameters.

Results: Median medication burden was higher in leukemia/lymphoma patients (6 orders) compared to solid (4 orders) or CNS tumor patients (4 orders, P = 0.006). Overall, the median number of prescriptions per patient did not change until death (P = 0.42), while there was a significant reduction for some medication subgroups (chemotherapy [P = 0.035], steroids [P = 0.010]).Patients dying in the ICU (n=15) had a higher medication burden at death (6 orders) than patients dying on wards (3 orders, P = 0.001). There was a trend for a reduction in medication burden in patients with “Do not resuscitate” (DNR) orders (P = 0.055).

Conclusions: Polypharmacy is ubiquitous among pediatric oncology patients at EOL. Disease type and DNR status may affect medication burden and deprescribing during the last hospitalization.

Background: The collapse of the Syrian healthcare system during the civil war led numerous citizens to cross the Syrian–Israeli border to seek medical care.

Objectives: To describe the epidemiology of peripheral nerve injuries (PNIs) sustained in war, their management, and short-term outcomes.

Methods: A retrospective case series study was conducted on 45 consecutive patients aged 25.7 ± 9.3 years. These patients were referred to the hand surgery unit of the department of orthopedic surgery and traumatology at Galilee Medical Center between December 2014 and June 2018. Median time between injury and presentation was 60 days. Injury pattern, additional injuries, surgical findings and management, complications, and length of hospital stay were extracted from medical records.

Results: Most injuries were blast (55.6%) followed by gunshot injuries (37.8%). There were 9 brachial plexus injuries, 9 sciatic nerve injuries, and 38 PNIs distal to the plexus: specifically 20 ulnar, 11 median, and 7 radial nerve injuries. In the latter group, neurotmesis or axonotmesis was found in 29 nerves. Coaptation was possible in 21 nerves necessitating cable grafting in 19. A tendon transfer was performed for 13 peripheral nerves, occasionally supplementing the nerve repair. The patients returned to their country after discharge, average follow-up was 53.6 ± 49.6 days.

Conclusions: For nerve injuries sustained in war, early surgical treatment and providing adequate soft tissue conditions is recommended. Tendon transfers are useful to regain early function.

Background: Patients admitted to the hospital after successful resuscitation from sudden cardiac death (SCD) are treated with therapeutic hypothermia (TH) to facilitate brain preservation. The prognostic significance of J (Osborn) waves (JOW) in the 12 leads electrocardiogram in this setting has not been elucidated as yet.

Objectives: To ascertain retrospectively the prognostic significance of JOW recorded during TH in SCD survivors.

Methods: The study comprised 55 consecutive patients who underwent TH. All patients achieved a core temperature of 33°C at the time of electrocardiogram analysis. We compared 33 patients with JOW to 22 patients without JOW. The endpoints were in-hospital, long-term all-cause mortality, and irreversible anoxic brain injury (IABI).

Results: Patients with JOW compared to patients without JOW were younger (55.1 ± 11.6 vs. 64.5 ± 11.7 years, respectively, P < 0.006), with a lower incidence of hypertension (52% vs. 86%, P < 0.007), diabetes mellitus (15% vs. 50%, P < 0.005), and congestive heart failure (15% vs. 45%, P < 0.013). In-hospital and long-term mortality were significantly higher in patients without JOW (86% vs. 21%, 91% vs. 24%, respectively, P < 0.000001). Among patients without JOW who survived hospitalization, 66.7% presented with IABI versus 7.7% of the patients with JOW (P < 0.0001). In multivariate analysis, the absence of JOW was a significant predictor for poor prognosis.

Conclusions: The absence of J (Osborn) waves on electrocardiograms obtained during TH is associated with poor prognosis among SCD survivors

Background: Pneumocystis jirovecii pneumonia (PJP) is an opportunistic infection in immunocompromised patients. Clusters of PJP, especially among organ transplant recipients in clinic settings were described. Data regarding nosocomial PJP infection among inpatients are limited.

Objectives: To assess the magnitude and characteristics of inpatient healthcare-associated PJP infection (HCA-PJP) in HIV-negative patients.

Methods: A retrospective chart review of hospitalized PJP patients was performed to identify HCA-PJP. The study was performed at six medical centers in Israel from 2006 to 2016. HCA-PJP was defined as cases of hospital-onset or those with documented contact with a PJP patient. We reviewed and cross-matched temporal and spatial co-locations of patients. Clinical laboratory characteristics and outcomes were compared.

Results: Seventy-six cases of PJP were identified. Median age was 63.7 years; 64% men; 44% hematological malignancies; 18% inflammatory diseases; and 61% steroid usage. Thirty-two patients (42%) were defined as HCA-PJP: 18/32 (23.6%) were hospitalized at onset and 14/32 (18.4%) had a previous encounter with a PJP patient. Time from onset of symptoms to diagnosis was shorter in HCA-PJP vs. community-PJP (3.25 vs. 11.23 days, P = 0.009). In multivariate analysis, dyspnea at presentation (odds ratio [OR] 16.79, 95% confidence interval [95%CI] 1.78–157.95) and a tendency toward higher rate of ventilator support (72% vs. 52%, P = 0.07, OR 5.18, 95%CI 0.7–30.3) were independently associated with HCA-PJP, implying abrupt disease progression in HCA-PJP.

Conclusion: HCA-PJP was common. A high level of suspicion for PJP among selected patients with nosocomial respiratory infection is warranted. Isolation of PJP patients should be considered
