Trends in the Incidence of Cardiovascular Diagnoses and Procedures over the Years 2012-2021 in Israel: The Impact of the COVID-19 Pandemic.

Prior studies found reduced incidences of cardiovascular diagnoses and treatments in the initial phase of the COVID-19 pandemic. However, these studies included a limited number of outcomes and did not consider pre-pandemic trends. This study aimed to describe trends in the incidence of cardiovascular diagnoses and treatments over the years 2012-2021 in Israel and to compare the two years of the COVID-19 period with the preceding 8 years. In this retrospective, population-based study, carried out within Clalit Health Services, the incidence rates of cardiovascular outcomes were calculated for individuals aged ≥ 25 (~2.7 million adults per year) during the first (Y1, 3/2020-2/2021) and second (Y2, 3/2021-2/2022) years of COVID-19 and the 8 years prior (3/2012-2/2020). Declines were observed in Y1 compared to 2019 in all diagnoses and treatments: STEMI (-16.3%; 95% CI: -16.6, -16.1), non-STEMI (-16.4%; -16.6, -16.2), AF (-14.1%; -14.2, -14.0), CHF (-7.8%; -7.9, -7.7), CVA (-5.0%; -5.0, -4.9), catheterization (-64.7%; -65.2, -64.2), CABG (-77.7%; -79.2, -76.2), ablation (-21.2%; -22.0, -20.4), pacemaker implantation (-39.3%; -40.7, -37.9), and defibrillator insertion (-12.5%; -13.1, -12.0). Compared with expected rates based on pre-pandemic trends, observed rates were within expected ranges (CHF, CVA, and ablation), less than expected (STEMI, non-STEMI, AF, catheterization, CABG, and pacemaker insertion), or more than expected (defibrillator insertion). In Y2, STEMI, catheterization, and CABG returned to expected rates; non-STEMI and AF were lower than expected; and CHF, CVA, ablation, and pacemaker and defibrillator implantations were higher than expected. Several cardiovascular diagnoses and treatment trends were interrupted by COVID-19. The long-term consequences of these changes should be considered by health policymakers.

Estimating the economic burden of long-Covid: the additive cost of healthcare utilisation among COVID-19 recoverees in Israel.

INTRODUCTION: Postacute sequelae resulting from SARS-CoV-2 infections (LONG-COVID) have been reported. The resulting added economic burden from the perspective of healthcare organisations is not clear. Therefore, this study aims to evaluate the additive healthcare costs among COVID-19 recoverees, in a large community-dwelling general population, as incurred by an insurer-provider organisation over time. METHODS: In this historical cohort study, cost data from Clalit Health Services (CHS) were analysed. The primary endpoint was the direct cost incurred by CHS per month per person. Costs were measured for COVID-19 recoverees and matched controls, from January 2019 to January 2022. Difference in differences (DiDs) were calculated as the difference in mean monthly costs in cases and controls in the post-COVID-19 individual period, deducing their cost difference in a prepandemic 12 months baseline period. RESULTS: Among N=642 868 community-dwelling COVID-19 recoverees, 268 948 (40.8%) were 0-19 years old and 63 051 (9.6%) were 60 years or older. A total of 16 017 (2.5%) of recoverees had been hospitalised during the acute phase of the COVID-19 disease. Costs in cases and controls converged after 16 months from recovery. The mean monthly cost incurred by CHS per COVID-19 recoverees over up to 15 months (mean: 8.25) of post-COVID-19 follow-up was higher by 8.2% (US$8.2) compared with matched controls. The excess cost attributable to post-COVID-19 effects (DID) was 7.6% of the cost in controls (US$7.7 per patient per month). Both net and relative DIDs were substantially higher in patients who required hospitalisation during the acute phase of COVID-19 and in older adults. Excess in hospitalisations, primary care physicians and medical specialists' visits-related costs were observed. CONCLUSIONS: Long-term effects of SARS-CoV-2 infections translate into excess healthcare costs, months after recovery, hence requiring adjustments of funds allocation. These excess costs gradually diminish after recoveree, returning to baseline differences 16 months after recoveree.

Examining the Patterns of Mpox Vaccine Uptake in a Vulnerable Population.

BACKGROUND: The current Mpox outbreak presents unique vaccination challenges in vulnerable populations. Understanding factors associated with vaccine uptake in vulnerable populations is required for a successful vaccination campaign. METHODS: This population-based cohort study was conducted in Clalit Health Services and included all individuals eligible for the Modified Vaccinia Ankara vaccine. Cox proportional hazards models were used to assess the characteristics associated with uptake of the first vaccine dose. RESULTS: Attendance to a primary healthcare clinic in the Tel Aviv district, repeated sexually transmitted infection screening, and the recent purchase of HIV-PrEP or PDE5 inhibitors were associated with higher vaccine adherence, whereas previous nonadherence with recommended vaccines, low sociodemographic status, and history of HIV were associated with lower adherence. CONCLUSIONS: These findings highlight the need for proactive patient and healthcare provider-oriented educational campaigns to curb vaccine hesitancy, and may help direct resources toward underserved populations, hence increasing equality in vaccine enrollment.

Risk assessment of human mpox infections: retrospective cohort study.

OBJECTIVES: The global supply of vaccines against mpox (previously called monkeypox virus infection) was significantly lower than the demand. Therefore, evidence-based vaccine prioritization criteria, based on risk assessment were needed. Our objective was therefore to identify the characteristics of individuals at the highest risk for mpox. METHODS: This population-based cohort study included all Clalit Health Services (CHS) subjects assumed to be at risk for mpox. The eligibility criteria for inclusion were determined based on known characteristics of people with infection worldwide and insights of lesbian, gay, bisexual, transgender, queer+ (LGBTQ+) -specialized CHS clinicians. Cox hazards models were used to identify the risk factors for mpox within the study cohort. The study commenced on 6 June 2022, the date of the first known mpox in CHS members, until 31 July 2022, when the mpox vaccination campaign started. RESULTS: A total of 8088 individuals of 4.7 million CHS members (0.18%) were identified according to the study inclusion criteria. Of those, 69 (0.85%) developed infection during the study period. Risk factors for mpox were birth in 1980 or later (hazard ratio, 5.04; 95% CI, 2.11-12.02), history of syphilis (2.62; 1.58-4.35), registration to primary healthcare clinics in the Tel Aviv district (2.82; 1.44-5.54), HIV-pre-exposure prophylaxis medication use (3.96; 2.14-7.31), PDE5 inhibitors use (2.92; 1.77-4.84), and recent sexually transmitted infections (STIs) within the last 18 months (2.27; 1.35-3.82). No infections were observed in individuals with none of the factors. Individuals with three or more risk factors had a 20.30-fold (10.39-39.69) higher risk for mpox compared with those with 0-2, with 85.5% (75.0-92.8%) sensitivity and 77.8% (76.9-78.7%) specificity. DISCUSSION: Weighting individuals' risk levels based on validated risk factors against vaccine availability can assist health systems in the equitable prioritization of vaccine allocation in various future outbreaks, given supply-demand gaps.

Real-world effectiveness of a single dose of mpox vaccine in males.

The recent global outbreak of the monkeypox (mpox) virus in humans was declared a public health emergency by the World Health Organization in July 2022. The smallpox and mpox vaccine (JYNNEOS; Modified Vaccinia Ankara-Bavarian Nordic; MVA-BN), provided as a two-dose regimen, is currently the primary vaccine utilized against mpox. However, the efficacy of MVA-BN against mpox has never been demonstrated in clinical trials to date. Due to the limited supply of vaccines, the World Health Organization has recommended prioritizing the vaccination of high-risk groups. We evaluated the real-world effectiveness of a single, subcutaneous dose of MVA-BN in this observational, retrospective cohort study, which included the analysis of electronic health records of all members of Clalit Health Services eligible for the vaccine on 31 July 2022. We used a Cox proportional hazards regression model with time-dependent covariates to estimate the association between vaccination and mpox while adjusting for sociodemographic and clinical risk factors. In an analysis of 2,054 male individuals who met vaccine eligibility criteria, 1,037 (50%) were vaccinated during the study recruitment period and completed at least 90 d of follow-up. During the study period, 5 and 16 infections were confirmed in vaccinated and unvaccinated individuals, respectively. The adjusted vaccine effectiveness was estimated at 86% (95% confidence interval, 59-95%). Our results suggest that a single dose of subcutaneous MVA-BN in this high-risk cohort is associated with a significantly lower risk of MPXV infection.

Factors Associated with Using Telemedicine in the Primary Care Clinics during the COVID-19 Pandemic in Israel.

BACKGROUND: The COVID-19 pandemic generated an extraordinary need for telemedicine. OBJECTIVE: To identify the factors and multi-way interactions associated with telemedicine use in primary healthcare during the COVID-19 pandemic. METHODS: This population-based study included all members (2,722,773) aged ≥18 years of the largest healthcare organization in Israel who used primary care clinic services between 1 March 2020 and 31 December 2021. Individuals were classified as telemedicine users (≥1 phone/video visits or asynchronous encounters) or non-telemedicine users (only in-person encounter/s). RESULTS: Ethnicity was the most discriminative variable associated with telemedicine use, with 85% and 52% users among Jews and Arabs, respectively. Higher odds for telemedicine utilization were observed among women, residents of urban areas, those confined to home, individuals with high level of technology literacy, residents of the central area (in Jews only), young Jews, and older Arabs. Based on decision tree analysis, the segments of the population with the lowest telemedicine use were characterized by lower primary care needs and comorbidities, as well as low technology literacy. The proportion of telemedicine use in these groups was 56% and 27% in Jews and in Arabs, respectively. CONCLUSION: A proactive intervention program should be applied among populations who are less likely to use telemedicine in the primary care clinics, including Arabs, Jews who live in the distant periphery, and individuals with low technology literacy.

Trends in the Volume and Types of Primary Care Visits during the Two Years of the COVID-19 Pandemic in Israel.

BACKGROUND: The outbreak of the COVID-19 pandemic led to a decrease in primary health care in-person visits and a simultaneous increase in virtual encounters. OBJECTIVE: To quantify the change in the total volume of primary care visits and mix of visit types during the two years of the pandemic in Israel. DESIGN: Cross-sectional study. PARTICIPANTS: All primary care visits by members of the largest healthcare organization in Israel, during three one-year periods: the pre-COVID-19 year (March 2019-February 2020), the first year of COVID-19 (March 2020-February 2021), and the second year of COVID-19 (March 2021-February 2022). MAIN MEASURES: Total volume of primary care visits and mix of visit types. RESULTS: More than 112 million primary care visits were included in the study. The total visit rate per 1000 members did not change significantly between the pre-COVID year (19) and the first COVID year (19.8), but was 21% higher in the second COVID-19 year (23). The rate of in-person visits per 1000 members decreased from 12.0 in the pre-COVID year to 7.7 in the first COVID year and then increased to 9.6 in the second. The rate of phone visits and asynchronous communication increased from 0.7 and 6.3, respectively, in the pre-COVID year, to 4.1 and 8, respectively, in the first COVID year, and remained unchanged in the second. There was substantial variation across age groups and sectors in the adoption of virtual platforms. CONCLUSIONS: The rapid introduction of virtual encounters in primary care tended to displace in-person visits in the first year of the pandemic, but they appear to have been additive in the second. This transition should be monitored, with the goal of ensuring appropriate planning efforts and resource allocation to deal with the potential added burden on medical staff. Efforts should be invested in encouraging the use of virtual platforms in patient groups that currently underutilize it, such as minorities.

Nirmatrelvir Use and Severe Covid-19 Outcomes during the Omicron Surge.

BACKGROUND: The oral protease inhibitor nirmatrelvir has shown substantial efficacy in high-risk, unvaccinated patients infected with the B.1.617.2 (delta) variant of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Data regarding the effectiveness of nirmatrelvir in preventing severe coronavirus disease 2019 (Covid-19) outcomes from the B.1.1.529 (omicron) variant are limited. METHODS: We obtained data for all members of Clalit Health Services who were 40 years of age or older at the start of the study period and were assessed as being eligible to receive nirmatrelvir therapy during the omicron surge. A Cox proportional-hazards regression model with time-dependent covariates was used to estimate the association of nirmatrelvir treatment with hospitalization and death due to Covid-19, with adjustment for sociodemographic factors, coexisting conditions, and previous SARS-CoV-2 immunity status. RESULTS: A total of 109,254 patients met the eligibility criteria, of whom 3902 (4%) received nirmatrelvir during the study period. Among patients 65 years of age or older, the rate of hospitalization due to Covid-19 was 14.7 cases per 100,000 person-days among treated patients as compared with 58.9 cases per 100,000 person-days among untreated patients (adjusted hazard ratio, 0.27; 95% confidence interval [CI], 0.15 to 0.49). The adjusted hazard ratio for death due to Covid-19 was 0.21 (95% CI, 0.05 to 0.82). Among patients 40 to 64 years of age, the rate of hospitalization due to Covid-19 was 15.2 cases per 100,000 person-days among treated patients and 15.8 cases per 100,000 person-days among untreated patients (adjusted hazard ratio, 0.74; 95% CI, 0.35 to 1.58). The adjusted hazard ratio for death due to Covid-19 was 1.32 (95% CI, 0.16 to 10.75). CONCLUSIONS: Among patients 65 years of age or older, the rates of hospitalization and death due to Covid-19 were significantly lower among those who received nirmatrelvir than among those who did not. No evidence of benefit was found in younger adults.

Continuous Decline in Myocardial Infarction and Heart Failure Hospitalizations during the First 12 Months of the COVID-19 Pandemic in Israel.

BACKGROUND: A decline in cardiovascular hospitalizations was observed during the initial phases of the COVID-19 pandemic. We examine the continuous effect of the COVID-19 pandemic in reducing cardiovascular hospitalization and associated mortality rates during the first year of the pandemic in Israel. METHODS: We conduct a retrospective cohort study using the data of Clalit Health Services, the largest healthcare organization in Israel. We divide the Corona year into six periods (three lockdowns and three post-lockdowns) and compare the incidence rates of cardiovascular hospitalizations and 30-day all-cause mortality during each period to the previous three years. RESULTS: The number of non-STEMI hospitalizations during the first year of the pandemic was 13.7% lower than the average of the previous three years (95% CI 11-17%); STEMI hospitalizations were 15.7% lower (95% CI 13-19%); CHF (Congestive heart failure) hospitalizations were 23.9% lower (95%, CI 21-27%). No significant differences in 30-day all-cause mortality rates were observed among AMI (acute myocardial infarction) patients during most of the periods, whereas the annual 30-day all-cause mortality rate among CHF patients was 23% higher. CONCLUSIONS: AMI and CHF hospitalizations were significantly lower during the first year of the pandemic relative to 2017-9. Mortality rates were higher in the case of CHF patients but not in the case of AMI patients, possibly due to a change in the clinical acuity of patients arriving at the hospitals. We conclude that targeted public health messaging should be implemented together with proactive monitoring, in order to identify residual disability in patients who may have received non-optimal treatment during the pandemic.

Area-level socioeconomic disparity trends in nutritional status among 5-6-year-old children in Israel.

OBJECTIVE: This study aimed to assess area-level socioeconomic position (SEP) disparities in nutritional status, to determine whether disparities differed by sex and to assess whether nutritional status and disparities changed over time. DESIGN: We used repeated cross-sectional data from a national programme that evaluates the quality of healthcare in Israel to assess children's nutritional status. SETTING: The study included all Israeli residents aged 7 years during 2014-2018 (n=699 255). METHODS: SEP was measured based on the Central Bureau of Statistics' statistical areas, and grouped into categories, ranging from 1 (lowest) to 10 (highest). We used multivariable multinomial regression to assess the association between SEP and nutritional status and between year and nutritional status. We included interactions between year and SEP to assess whether disparities changed over time. RESULTS: Children in SEP 1, comprised entirely of children from the Bedouin population from Southern Israel, had drastically higher odds of thinness compared with those in the highest SEP (Girls: OR 5.02, 99% CI 2.23 to 11.30; Boys: OR 2.03, 99% CI 1.19 to 3.48). Odds of obesity were highest in lower-middle SEPs (ORSEP 5 vs 10 1.84, 99% CI 1.34 to 2.54). Prevalence of overweight and obesity decreased between 2014 and 2018, normal weight increased and thinness did not change. SEP disparities in thinness decreased over time in boys but showed a reverse trend for girls. No substantial improvement was seen in SEP disparities for other weight categories. CONCLUSIONS: Our study demonstrates the need to consider initiatives to combat the considerable SEP disparities in both thinness and obesity.

[ANTIBIOTIC USE IN COMMUNITY HEALTHCARE IN ISRAEL AS REFLECTED IN THE NATIONAL PROGRAM FOR QUALITY INDICATORS].

AIMS: We sought to evaluate the extent of overall and second-line systemic antibiotic use in the Israeli community, to compare them to international data and to monitor temporal trends. BACKGROUND: Antibiotic overuse is prevalent and has grave implications, primarily the emergence of resistant pathogens - an urgent public health concern worldwide. METHODS: The Israel National Program for Quality Indicators in Community Healthcare (QICH) obtains data from electronic medical records from the 4 health-plans, covering the entire civilian population. We assessed 2 quality indicators, compatible with those of the OECD: 1. Overall volume of antibiotics for systemic use dispensed. 2. Volume of second-line antibiotics as a proportion of all systemic antibiotics. Analysis was stratified by gender, age and socio-economic position (SEP). RESULTS: The volume of systemic antibiotics dispensed in 2016 was 20.76 DDD/1000 person/day, with second-line antibiotics comprising 22.0% of the total. These values have been stable since 2014, and are higher compared with the OECD averages (20.61 DDD/1000 person/day, and 17.02% in 2015). Both overall volume and the proportion of second-line antibiotics rose with age and were higher among women especially in the 20-40 years age bracket (overall volume of 23.98 DDD/1000 person/day, proportion of second-line antibiotics of 23.98% VS 17.41 and 19.17% in men). Higher overall use was observed among patients of low SEP. CONCLUSIONS: The observed volume of systemic antibiotics and the proportion of second-line antibiotics dispensed in the Israeli community were stable and high. Higher use was observed among older individuals, women and patients of low SEP. Our results call for the implementation of a national-level, community-based antibiotic stewardship program. QICH might serve to monitor such a program.
