Exploring pre-MRI imaging tests: patient survey reveals potential implications for healthcare efficiency in Israel.

BACKGROUND: Medical imaging tests are vital in healthcare but can be costly, impacting national health expenditures. Magnetic resonance imaging (MRI) is a crucial diagnostic tool for assessing medical conditions. However, the rising demand for MRI scans has frequently strained available resources. This study aimed to estimate the prevalence of different imaging tests in individuals who eventually had an MRI, in the Israeli public health system. METHODS: An online survey of patient experience of scheduling an MRI was conducted in January-February 2023, among 557 Israeli adults, representing all four health maintenance organizations (HMOs). All participants had undergone an MRI in the public health system within the past year. RESULTS: Results showed that 60% of participants underwent other imaging tests before their MRI scan. Of those, computed tomography (CT) scans (43%), X-rays (39%), and ultrasounds (32%) were the most common additional imaging procedures. In addition, of the 60% of participants, 23% had undergone more than one prior imaging examination. CONCLUSIONS: These findings highlight the high prevalence of preliminary imaging tests prior to MRI, with many patients undergoing multiple tests for the same problem. The health system may need to evaluate whether current clinical guidelines defining the use of various imaging tests are cost-effective.

Priority setting for health technology adoption at the national level: Lessons learned over 25 years' experience.

BACKGROUND: Limited health budgets and continual advancement of health technologies require mechanisms for prioritization. Israel, with a publicly funded health service basket, has implemented and optimized such a health technology assessment process since 1999.We describe the process of evaluating technologies according to the Israeli model, analyze its outputs and benefits over two decades of implementation, and compare its key features with international experience. METHODS: Retrospective data were collected between 1998 and 2023, including work processes, committee composition, number of applications submitted and approved by a clinical domain, and yearly cost of the basket. Features were evaluated within the evidence-informed deliberative process (EDP) framework. RESULTS: This national model involves relevant stake holders in a participatory and transparent process, in a timely manner, and is accepted by the public, health professionals, and policy makers, facilitating early adoption of the newest medical technologies. Between 11 and 19 percent of applications are approved for reimbursement annually, mostly pharmaceuticals. On average 26 percent of approved technologies are added to the list without additional budget. Major domains of approved technologies were oncology, cardiology, and neurology. CONCLUSIONS: Israel created a unique model for the expansion of the health service basket. Despite an increasing number of applications and rising costs, the mechanism enables a consensus to be reached on which technologies to fund, while remaining within budget constraints and facilitating immediate implementation. The process, which prioritizes transparency and stake holder involvement, allows just a resource allocation while maximizing the adoption of novel technologies, contributing to an outstanding national level of health despite relatively low health spending.

Cross-cultural adaptation of the Parental Perceptions of Children's Exposure to Tobacco Smoke instrument to the Brazilian context.

OBJECTIVE: To perform a cross-cultural adaptation of the Parental Perceptions of Children's Exposure to Tobacco Smoke (PPE) instrument to the Brazilian context. RESULTS: The cross-cultural adaptation process was performed in 10 stages. Four translators, eight specialists, and 35 primary care users participated in the study. Both translations were similar. The synthesis version that was back-translated was equivalent to the original. The committee of experts scored all items in the content validity index as 3 or 4, suggesting only small changes such as changing "photo" to "image" and "service balcony" to "service area". After the completion of the first sequence of pretests, some adjustments were required by the committee of experts for the second round. The form of application of the self-administered questionnaire for the interview was changed, the Likert scale was reduced from 7 to 5 points, and the option "I don't know" was added to questions 18, 19, and 20. After these adjustments, the instrument was well accepted by the study population and presented good internal consistency (Cronbach's α score = 0.82). The PPE instrument, which assesses the perception of parents about their children's exposure to cigarette smoke, was satisfactorily translated and adapted to the Brazilian context.

Inequalities in end-stage renal disease: underprivileged and ethnic minority members are at higher risk.

BACKGROUND: Incidence of end-stage renal disease (ESRD) is higher in Israel than the European average. Socio-economic differences in ESRD have been reported globally, but many countries lack a national register. Using national data, we assessed which socio-demographic factors are associated with 5-year incidence of ESRD in Israel, where there is universal access to renal replacement therapy (RRT). METHODS: Data on all incident ESRD cases aged ≥20 years receiving chronic RRT between 1 January 2014 and 31 December 2018 (N = 7883) were collected from Israel's National Dialysis & Renal Transplant Register. Individual-level data on ESRD cases requiring RRT included residential area, age, gender, ethnicity (Jewish or Arab) and ESRD cause (diabetes, other, unknown/missing). Area-level data included age and sex distribution, socio-economic status (SES) and proportion of Arab population. The associations between individual-level socio-demographic characteristics and ESRD cause were tested in bivariate comparisons. The risk of developing ESRD during the study period (from all and specific causes) was estimated using multiple Poisson regression models with negative binomial distribution, using four parameters, namely sex, ethnicity, SES category and age strata, based on area-level distribution of these parameters, and with the whole population (aged ≥20 years) as the denominator. RESULTS: A socio-economic gradient was seen for ESRD from all causes, more marked for diabetic aetiology [rate ratio (RR)=0.45, 95% CI: 0.39-0.52 highest vs lowest SES categories] than from other (RR = 0.64, 95% CI: 0.55-0.75) or unknown cause (RR = 0.79, 95% CI: 0. 62-0.99). Based on population area-level data, predominantly Arab neighbourhoods showed higher risk for ESRD requiring RRT for all causes, with the strongest association for diabetes (RR = 1.69, 95% CI: 1.53-1.86) adjusted for SES, age and sex. CONCLUSIONS: A strong socio-economic gradient was demonstrated for ESRD requiring RRT. Arab ethnicity was associated with higher risk for ESRD, especially due to diabetes. Our findings suggest the need for allocation of health resources according to needs and culturally appropriate interventions for improving control of modifiable risk factors for chronic renal failure.

Tobacco Smoke Exposure According to Location of Home Smoking in Israel: Findings from the Project Zero Exposure Study.

Young children are particularly vulnerable to harms from tobacco smoke exposure (TSE). This study aimed to compare TSE: (1) between children who live in smoking families and those who do not; and (2) among children who live in smoking households with varying smoking locations. The data came from two studies that were conducted concurrently in Israel (2016-2018). Study 1: a randomized controlled trial of smoking families (n = 159); Study 2: a cohort study of TSE among children in non-smoking families (n = 20). Hair samples were collected from one child in each household. Baseline hair nicotine data were analyzed for 141 children in Study 1 and 17 children in Study 2. Using a logistic regression analysis (exposed vs. not exposed as per laboratory determination) and a linear regression (log hair nicotine), we compared TSE between: (1) children in Study 1 vs. Study 2; (2) children in families with different smoking locations in Study 1: balcony; garden, yard, or other place outside of the home; or inside the home (designated smoking areas within the home (DSAs) or anywhere). A higher proportion of children living in smoking households were measurably exposed to tobacco smoke (68.8%) compared to children living in non-smoking households (35.3%, p = 0.006). Among children from smoking families, 75.0% of those whose parents smoked in the house were exposed, while 61.8% of children whose parents restricted smoking to the porch (n = 55) were exposed, and 71.4% of those whose parents smoked outside the home (including gardens and yards) (n = 42) were exposed. In univariable and multivariable models, smoking location was not significantly associated with exposure. The majority of children in smoking families were measurably exposed to TSE, even if smoking was restricted to designated areas in the home, balconies, orgarden/yard/other outdoor areas. Reducing population smoking rates, particularly among parents, restricting smoking to at least 10 meters from homes and children, and denormalizing smoking around others are recommended to reduce population-level child TSE and tobacco-attributable disease and death.

Timely childhood vaccination in Israel: a national retrospective study of ethnic and socioeconomic disparities.

A large proportion of children do not receive vaccines within the recommended timeframe. This study examined ethnic and socioeconomic differences in age-appropriate immunization of children in Israel, where immunization is freely available. Percent of children receiving MMR/V at 12-13 months, and four doses of DTP/IPV/Hib by 18 months were obtained from the National Programme for Quality Measures between 2015 and 2018. Ethnic group (Jewish vs Arab) (defined by proxy by the neighbourhood in which the clinic was located), neighbourhood socioeconomic status and peripherality were obtained. Rates of MMR vaccination were 61% in the Jewish and 82% in the Arab population; for DPT/IPV/Hib 75% in the Jewish, compared to 92% in the Arab population. These patterns were stable over time. Lowest rates occurred in the most peripheral areas for Arab children, and in urban areas for Jewish children. Differences between ethnic groups were significant at higher SES levels. Greater adherence to the vaccination schedule occurred in the Arab minority in contrast to studies showing lower vaccination in ethnic minorities elsewhere. Lower immunization rates among rural Arab children suggest a need for improved access to clinics. Efforts should be directed towards lower SES groups, while emphasizing the importance of timely vaccination in wealthier groups in order to achieve herd immunity.

A health promotion perspective for the control and prevention of Brucellosis (Brucella melitensis); Israel as a case study.

BACKGROUND: Brucellosis (Brucella melitensis) is endemic in many countries around the world, therefore, identifying what is required to control and prevent the disease is essential. The health promotion concept and five areas of action, presented in the Ottawa Charter (1986) may help understand how to go forward in the prevention of the disease. Israel serves as a case study. AIM: To identify barriers to the control and prevention of brucellosis (Brucella melitensis) in Israel by analyzing trends in incidence in conjunction with interventions implemented over the last seven decades, applying the health promotion areas of action. METHODS: 1. A document review approach was adopted to develop a list of interventions implemented in Israel to prevent and control brucellosis and identify barriers to implementation. These were analysed using the health promotion areas of action. 2. Data from the mandatory reporting of infectious diseases in Israel regarding brucellosis in humans between 1951 and 2021 are presented and analyzed in conjunction with the interventions implemented. RESULTS: A large range of interventions were implemented following outbreaks of the disease. These interventions followed the health promotion areas of action, including mainly: policy, education and environment and brought about a decrease in the disease among both animals and humans. However, major interventions were discontinued after a few years. In addition, we identified some areas of action that could be much improved on. The interventions, in many cases were not simultaneously implemented or coordinated, decreasing the chances of them having the expected long term impact. CONCLUSIONS: Control and prevention of the disease in Israel is partial. Areas of action that could be improved include enforcement of regulations, strengthening community action and improving personal skills. Simultaneous and continuous implementation of the interventions may achieve the goals of sustained prevention and control. There seems to be a lack of a long-term strategy and an integrated holistic intervention approach that may contribute to the control and prevention of the disease.

COVID-19 Vaccination, Morbidity, and Mortality During a 12-Month Period in Israel: Can We Maintain a "Herd Immunity" State?

Despite widespread vaccination, the COVID-19 pandemic continues to cause global disruption. Authors describe the pace of COVID-19 vaccination in Israel and examine differences in morbidity and mortality rates over time between vaccinated and unvaccinated populations. Retrospective data were obtained between December 2020 and December 2021 on daily vaccine uptake by age group (20-39, 40-59, 60+ years): rate of hospitalized severely ill cases, vaccination status and age group, and death rate per 100,000 by date and vaccination status. Uptake of first and second doses was slower in 20-59-year olds, whereas in 60+-year olds, it occurred without delay. Once most adults were vaccinated, a gap appeared with much higher severe cases and deaths in unvaccinated versus vaccinated populations; this gap attenuated by late May with very low rates in both vaccinated and unvaccinated populations until mid-July, when rates began to rise again. A herd-immunity-like period occurred in Spring 2021, with unvaccinated benefitting from a highly vaccinated population. Staggered vaccine uptake led to unsynchronized high immunity, which contributed to the fourth pandemic wave. Population vaccination within a shorter timeframe or shorter intervals between boosters may be important to reduce viral transmission.

Covid-19 in children aged 5-11: Examining the issues surrounding vaccination and public health policy.

BACKGROUND: Children under 12 are now the largest unvaccinated group. Following FDA approval, vaccination of 5-11 year olds is now being encouraged in some countries. We present data on child COVID-related morbidity in Israel and discuss the complexities surrounding vaccinating children aged 5-11. METHODS: Data were obtained from Israel's open COVID database regarding new confirmed daily COVID-19 cases, severe hospitalized cases and deaths by age group in Israel from February 2020-November 2021, as well as vaccination rate and adverse events following vaccination. RESULTS: In 5-11 year olds, there were 460 hospitalizations, including 72 moderate to critical (0.007% population rate), with 3 deaths (0.0003% population rate). Children (0-19) made up the largest proportion (41%) of cases, but comprised just <0.1% of deaths, and <1% of severe cases. Post-vaccine myocarditis was much lower than severe COVID risk except in boys aged 12-19 where it was equivalent to the risk of mechanical ventilation due to COVID in boys aged 10-19 (12 per 100,000). High numbers of children were quarantined. CONCLUSIONS: COVID risk is minimal for most children though rare complications do occur. Israeli and US pediatric associations have recommended vaccinating children, particularly in high-incidence scenarios where risk-benefit balance is more clear-cut. However only a quarter of eligible parents have vaccinated their children. Parents may consider health grounds but also restrictions on children, population vaccination levels, waning immunity and new variants, and should be provided with clear information to help them make an informed decision. Policymakers should reevaluate the need for isolations, testing and mask-wearing in school age children, which are detrimental to their wellbeing.

Factors Affecting the Patient Journey in Scheduling a Specialist Appointment in a Public Healthcare System.

A questionnaire was developed to evaluate the journey experienced by patients from identifying a need to see a community specialist in Israel's public healthcare system, through scheduling an appointment and attending. A telephone survey was conducted with a nationally representative group of 3751 adults, in 2019 to 2020. Fifty-seven percent needed to see a specialist in the last 6 months; among those, 82%, visited a specialist. Among the 3% who did not make an appointment, in 41 of 52 (79%) cases this was due to long waiting time. Younger and more educated patients were more likely to try to get an earlier appointment. Timeliness (55%) and wanting a specific physician (43%) were major considerations in scheduling. Reported need was greater in females, Jewish versus Arab respondents, more educated and those with chronic illness. Those who did not make an appointment sought private care, emergency treatment, or went untreated. Although a large percentage of respondents did eventually get an appointment, vulnerable patients may have more difficulty navigating the system. Following the patient journey can provide insights to help design services better suited to patients' needs.

Sociodemographic disparities in COVID-19 burden: changing patterns over four pandemic waves in Israel.

BACKGROUND: Worldwide, the COVID-19 pandemic hit weakest populations hardest, with socioeconomic (SE), racial and ethnic disparities in COVID-19 burden. The study aimed to analyse patterns of SE and ethnic disparities in morbidity, hospitalisation, and vaccination throughout four pandemic waves. METHODS: A retrospective-archive study was conducted in Israel from 11 March 2020 to 1 December 2021, with data on confirmed cases, hospitalisations, mortality and vaccinations (three doses), obtained from the Israeli Ministry of Health's open COVID-19 database, covering 98.8% of the population, by SE and ethnic characteristics of localities. FINDINGS: At the outbreak of the pandemic, there was a higher caseload in Jewish, compared with Arab localities. In the second and third waves, low SE and Arab minority populations suffered 2-3 times higher morbidity, with a similar but attenuated pattern in the fourth wave. A similar trend was observed in hospitalisation of confirmed patients. COVID-19-associated mortality did not demonstrate a clear SE gradient.A strong social gradient in vaccine uptake was demonstrated throughout the period, with 71% and 74% double vaccinated in the two highest SE clusters, and 43% and 27% in the two lowest clusters by December 2021. Uptake of the third dose was 57%-60% in the highest SE clusters and 31%-25% in the lowest clusters. SE disparities in vaccine uptake were larger among the younger age groups and gradually increased from first to third doses. CONCLUSIONS: Israel was among the first to lead a rapid vaccination drive, as well as to experience a fourth wave fuelled by diminishing immunity and the delta variant. SE and ethnic disparities were evident throughout most of the pandemic months, though less so for mortality. Despite higher COVID-19 burden, vaccine uptake was lower in disadvantaged groups, with greater disparities in the younger population which widened with subsequent doses.

Clinical decision support system recommendations: how often do radiologists and clinicians accept them?

OBJECTIVE: To assess the acceptance and reliability of clinical decision support system (CDSS) imaging referral scores (ESR iGuide). METHODS: A pilot study was conducted in a tertiary hospital. Four different experts were invited to rate 40 simulated clinical cases on a 5-level scale, for the level of agreement with the ESR iGuide's recommended procedures. In cases of disagreement, physicians were asked to indicate the reason. Descriptive measures were calculated for the level of agreement. We also explored the degree of agreement between four different specialists, and examined the cases in which clinicians disagreed with ESR iGuide best practice recommendations. RESULTS: The mean rating of the four experts for the 40 clinical simulated cases was 4.17 ± 0.65, median 4.25 (on a scale of 1-5). All four raters totally agreed with the system recommendation in 75% of cases. No significant relationship was found between the degree of agreement and the number of indications and the patient's age or gender. In an optimistic scenario, using a binary agree/disagree variable, the Overall Percentage Agreement for the rating of the 40 simulated cases between the four experts was 77.28%. There were a total of 20 disagreements out of 160 cases with the ESR iGuide, of which 7 were among the two radiologists. CONCLUSIONS: CDSS can be an effective tool for guiding the selection of appropriate imaging examinations, thus cutting costs due to unnecessary imaging scans. Since this is a pilot study, further research on a larger scale, preferably at national level, is required. KEY POINTS: • The average of the mean rating of the four experts was 4.17 ± 0.65, median 4.25, on a scale of 1-5 where 5 represents total agreement with the CDSS tool. • In an optimistic scenario, using a binary agree/disagree variable, the Overall Percentage Agreement between the four experts was 77.28%. • Radiologists had fewer disagreements with the recommendations of the CDSS tool than other physicians, indicating a better fit of the support system to radiology experts' perspective.

The effect of the COVID-19 pandemic on non-COVID respiratory ED visits in Israel.

BACKGROUND: The COVID 19 pandemic has had a crucial effect on the patterns of disease and treatment in the healthcare system. This study examines the effect of the COVID-19 pandemic on respiratory ED visits and admissions broken down by age group and respiratory diagnostic category. METHODS: Data on non-COVID related ED visits and hospitalizations from the ED were obtained in a retrospective analysis for 29 acute care hospitals, covering 98% of ED beds in Israel, and analyzed by 5 age groups: under one-year-old, 1-17, 18-44, 45-74 and 75 and over. Diagnoses were classified into three categories: Upper respiratory tract infections (URTI), pneumonia, and COPD or asthma. Data were collected for the whole of 2020, and compared for each month to the average number of cases in the three pre-COVID years (2017-2019). RESULTS: In 2020 compared to 2017-2019, there was a decrease of 34% in non-COVID ED visits due to URTI, 40% for pneumonia and a 35% decrease for COPD and asthma. Reductions occurred in most age groups, but were most marked among infants under a year, during and following lockdowns, with an 80% reduction. Patients over 75 years old displayed a marked drop in URTI visits. Pediatric asthma visits fell during lockdowns, but spiked when restrictions were lifted, accompanied by a higher proportion admitted. The percent of admissions from the ED visits remained mostly stable for pneumonia; the percent of young adults admitted with URTI decreased significantly from March to October. CONCLUSIONS: Changing patterns of ED use were probably due to a combination of a reduced rate of viral diseases, availability of additional virtual services, and avoidance of exposure to the ED environment. Improved hygiene measures during peaks of respiratory infections could be implemented in future to reduce respiratory morbidity; and continued provision of remote health services may reduce overuse of ED services for mild cases.

Uptake of coronavirus disease 2019 (COVID-19) vaccination among general hospital staff in Israel.

Data from all general hospitals in Israel to April 2021 show that the mean hospital rate of staff vaccination was 84.4% for the first dose and 77.1% for the second dose, which are lower than general population rate, with mean 7% who did not complete their vaccinations. Healthcare workers have an important role in influencing the wider community.

Developing a National Set of Health Equity Indicators Using a Consensus Building Process.

BACKGROUND: Considerable health inequities documented in Israel between communities, populations and regions, undermine the rights of all citizens to optimal health. The first step towards health equity is agreement on a set of national indicators, reflecting equity in healthcare provision and health outcomes, and allowing monitoring of the impact of interventions on the reduction of disparities. We describe the process of reaching a consensus on a defined set of national equity indicators. METHODS: The study was conducted between January 2019 and June 2020, in a multistage design: (A) Identifying appropriate and available inequity measures via interviews with stakeholders. (B) Agreement on the screening criteria (public health importance; gap characteristics; potential for change; public interest) and relative weighting. (C) Constructing the consultation framework as an online, 3-round Delphi technique, with a range of experts recruited from the health, welfare and education sectors. RESULTS: Participants were of diverse age, gender, geographic location, religion and ethnicity, and came from academia, healthcare provision, government ministries and patient representative groups. Thirty measures of inequity, presented to participants, represented the following domains: Health promotion (11 indicators), acute and chronic morbidity (11), life expectancy and mortality (2), health infrastructures and affordability of care (4), education and employment (2). Of the 77 individuals contacted, 75 (97%) expressed willingness to participate, and 55 (73%) completed all three scoring rounds. The leading ten indicators were: Diabetes care, childhood obesity, adult obesity, distribution of healthcare personnel, fatal childhood injuries, cigarette smoking, infant mortality, ability to afford care, access to psychotherapy and distribution of hospital beds. Agreement among raters, measured as intra-class correlation coefficient (ICC), was 0.75. CONCLUSION: A diverse range of consultants reached a consensus on the most important national equity indicators, including both clinical and system indicators. Results should be used to guide governmental decision-making and inter-sectoral strategies, furthering the pursuit of a more equitable healthcare system.

Design and implementation of a multifaceted injury prevention intervention in Bedouin children in southern Israel.

BACKGROUND: Child injury is prevalent in the Bedouin community of southern Israel, with higher injury rates compared with the general population. Bedouin children aged 0-4 were twice as likely as children from other population groups to suffer any injury, and for example, incidence of burns in Bedouin children was 0.91/1000 children, compared with 0.46/1000 in Jewish children. METHODS: A multifaceted injury prevention intervention was developed based on best practice methods, culturally adapted and implemented in nine Bedouin towns in collaboration with local authorities. Intervention elements included a youth leadership scheme, workshops for mothers in maternal child health centres, home safety visits, a preschool intervention and a media campaign. Outcome assessment of change following home visits was conducted. Process evaluation included a survey of mothers and focus groups with youth participants. RESULTS: High participation was demonstrated indicating acceptability of the programme. Assessment of home visits showed an improvement in the level of household safety between first and second visits, as measured by a checklist. Youth participants expressed satisfaction in the programme, which gave them confidence and practical tools. CONCLUSION: A multifaceted intervention programme was conducted in the Bedouin community in southern Israel and found to be acceptable, with high participation levels. Collaboration between national and local authorities improved implementation, and multiple programmes in different settings enabled broad exposure to the programme.

Evaluation of an intervention to reduce child injury in Bedouin communities in Southern Israel.

BACKGROUND: Child injury is particularly prevalent in low socioeconomic populations and minorities. In Israel, Bedouin children exhibit high rates of injuries and death. A multifaceted community intervention to reduce injury in children in and around the home was run in nine Bedouin communities in Southern Israel during 2014-2018. The aim of the study was to evaluate the effect of the intervention on injuries among children aged 0-4 by comparing emergency room (ER) visits and hospitalisations before and after the intervention. METHODS: Child injury data (ages 0-4, 5-17) for 2013-2018 were obtained from Soroka Medical Center, including ER visits and hospitalisations. Further data on reason for hospitalisation and injury severity score (ISS) were obtained from the National Centre for Trauma Research for 2011-2018. Reach was assessed by calculating the per cent of participants from the total relevant population in each town. Poisson regression was used to assess change over time, from preintervention (2013) to postintervention (2018). RESULTS: A high proportion of educational institutions took part in the intervention, and around 20% of relevant households received a home visit (n=6334). There was a significant reduction in ER visits (7.6%) in children aged 0-4 in 2018 compared with 2013. Hospitalisations did not decrease significantly, although the number of admissions for burns and falls was reduced significantly at follow-up. CONCLUSIONS: This multifaceted intervention programme resulted in reduced injury in children aged 0-4 years in the Bedouin community. The use of simultaneous multiple intervention methods was effective in increasing child safety.

Effect of Socioeconomic and Ethnic Characteristics on COVID-19 Infection: the Case of the Ultra-Orthodox and the Arab Communities in Israel.

BACKGROUND: During infectious disease outbreaks, the weakest communities are more vulnerable to infection and its deleterious effects. In Israel, the Arab and Ultra-Orthodox Jewish communities have unique demographic and cultural characteristics that place them at higher risk of infection. OBJECTIVE: To examine socioeconomic and ethnic differences in rates of COVID-19 testing, confirmed cases and deaths, and to analyze patterns of transmission in ethnically diverse communities. METHODS: A cross-sectional ecologic study design was used. Consecutive data on rates of COVID-19 diagnostic testing, lab-confirmed cases, and deaths collected from March 31 through May 1, 2020, in 174 localities across Israel (84% of the population) were analyzed by socioeconomic ranking and ethnicity. RESULTS: Tests were performed on 331,594 individuals (4.29% of the total population). Of those, 14,865 individuals (4.48%) were positive for COVID-19 and 203 died (1.37% of confirmed cases). Testing rate was 26% higher in the lowest SE category compared with the highest. The risk of testing positive was 2.16 times higher in the lowest socioeconomic category, compared with the highest. The proportion of confirmed cases was 4.96 times higher in the Jewish compared with the Arab population. The rate of confirmed cases in 2 Ultra-Orthodox localities increased relatively early and quickly. Other Jewish and Arab localities showed consistently low rates of confirmed COVID-19 cases, regardless of socioeconomic ranking. CONCLUSIONS: Culturally different communities reacted differently to the COVID-19 outbreak and to government measures, resulting in different outcomes. Socioeconomic and ethnic variables cannot fully explain communities' reaction to the pandemic. Our findings stress the need for a culturally adapted approach for dealing with health crises.

Changes in infectivity, severity and vaccine effectiveness against delta COVID-19 variant ten months into the vaccination program: The Israeli case.

We present epidemiological data to examine trends in COVID-19 incidence, morbidity and mortality in Israel as well as changes in vaccine effectiveness, and discuss the impact of the delta variant and the third, "booster", vaccine. A retrospective-archive study was conducted from February 27th 2020 to October 16th, 2021. Data were obtained from the Israeli Ministry of Health's open COVID 19 database, including PCR-confirmed cases, number hospitalized - including severe cases, death rate, all by age and vaccination status, case fatality rate and changing effectiveness of the vaccine. After three COVID waves, confirmed cases rose from under 30 new daily cases in mid-June to a high of 11,000 in early September 2021. Severe hospitalized cases and death rates were lower than in previous waves and largely restricted to those not fully vaccinated. In the first three months of the vaccination campaign, non-vaccinated population demonstrated much higher morbidity rates. Four months after vaccination began, this gap was attenuated, with low rates of infection and hospitalization in all groups. The gap was regained following uptake of the third vaccine. Data from the fourth wave show reduced hospitalizations and mortality compared to previous waves and suggest that this may be related to high vaccine coverage. These trends suggest that countries with high vaccination might adopt a more permissive approach towards COVID even in the face of new variants.

Socioeconomic gradient in COVID-19 vaccination: evidence from Israel.

BACKGROUND: Low socioeconomic status (SES) groups have been disproportionately affected by the COVID-19 pandemic. We aimed to examine COVID-19 vaccination rate by neighborhood SES and ethnicity in Israel, a country which has achieved high vaccination rates. METHODS: Data on vaccinations were obtained from the Israeli Ministry of Health's open COVID-19 database, for December 20, 2020 to August 31, 2021. Correlation between vaccination rate and neighborhood SES was analyzed. Difference in vaccination rate between the first and second vaccine dose was analyzed by neighborhood SES and ethnicity. FINDINGS: A clear socioeconomic gradient was demonstrated, with higher vaccination rates in the higher SES categories (first dose: r = 0.66; second dose: r = 0.74; third dose: r = 0.92). Vaccination uptake was lower in the lower SES groups and in the Arab population, with the largest difference in uptake between Jewish and Arab localities for people younger than 60, and with the gap widening between first and third doses. CONCLUSIONS: Low SES groups and the Arab ethnic minority demonstrated disparities in vaccine uptake, which were greater for the second and third, compared with the first vaccine dose. Strategies to address vaccination inequity will need to identify barriers, provide targeted information, and include trust-building in disadvantaged communities.
