To determine if people infected with SARS-CoV-2 were at higher risk of developing selected medical conditions post-recovery, data were extracted from the database of a large health maintenance organization (HMO) in Israel between March 2020 and May 2021. For each condition, a condition-naïve group prior to COVID-19 (PCR-positive) infection were compared to a condition-naïve, non-COVID-19 infected group, matched by gender, age, socioeconomic status, minority group status and number of months visited primary care physician (PCP) in previous year. Diagnosis and recuperation dates for each COVID-19 infected participant were applied to their matched comparison participant (1:1 ratio).

Background: Diabetes is a major public health issue. Because lifetime risk, life expectancy, and years of life lost are meaningful metrics for clinical decision making, we aimed to estimate these measures for type 2 diabetes in the high-income setting.

Methods: For this multinational, population-based study, we sourced data from 24 databases for 23 jurisdictions (either whole countries or regions of a country): Australia; Austria; Canada; Denmark; Finland; France; Germany; Hong Kong; Hungary; Israel; Italy; Japan; Latvia; Lithuania; the Netherlands; Norway; Scotland; Singapore; South Korea; Spain; Taiwan; the UK; and the USA.

Background: Population-level trends in mortality among people with diabetes are inadequately described. We aimed to examine the magnitude and trends in excess all-cause mortality in people with diabetes.

Methods: In this retrospective, multicountry analysis, we collected aggregate data from 19 data sources in 16 high-income countries or jurisdictions (in six data sources in Asia, eight in Europe, one from Australia, and four from North America) for the period from Jan 1, 1995, to Dec 31, 2016, (or a subset of this period) on all-cause mortality in people with diagnosed total or type 2 diabetes.

Background: Diabetes prevalence is increasing in most places in the world, but prevalence is affected by both risk of developing diabetes and survival of those with diabetes. Diabetes incidence is a better metric to understand the trends in population risk of diabetes. Using a multicountry analysis, we aimed to ascertain whether the incidence of clinically diagnosed diabetes has changed over time.

Background: The salutary effects of statin therapy in patients with cardiovascular disease (CVD) are well established. Although generally considered safe, statin therapy has been reported to contribute to induction of diabetes mellitus (DM).

Objectives: To assess the risk-benefit of statin therapy, prescribed for the prevention of CVD, in the development of DM.

Background: In 2012, Maccabi Healthcare Services founded Maccabi Telecare Center (MTC), a multi-disciplinary healthcare service providing telemedical care to complex chronic patients. The current paper describes the establishment and operation of the MTC center, from the identification of the need for the service, through the design of its solution elements, to outcomes in several areas of care. We analyze the effects of the program on elderly frail patients, a growing population with complex and costly needs.

Purpose: To evaluate the association between levonorgestrel-releasing intrauterine system (LNG-IUS) use and breast cancer (BC) risk.

Methods: A cohort of all Maccabi Healthcare Services (MHS) female members aged 40-50 years between 1/2003 and 12/2013 was used to identify LNG-IUS users as "cases," and 2 age-matched non-users as "controls." Exclusion criteria included: prior BC diagnosis, prior (5 years pre-study) and subsequent treatment with other female hormones or prophylactic tamoxifen.

Background: Developmental dysplasia of the hip (DDH) occurs in 3-5 of 1000 live births and is associated with known risk factors. In most countries, formal practice for early detection of DDH entails the combination of risk factor identification and physical examination of the hip, while the golden standard diagnostic instrument is hip ultrasonography (US). This practice is commonly referred to as selective screening.

Background: Primary Care Health organizations, operating under universal coverage and a regulated package of benefits, compete mainly over quality of care. Monitoring, primary care clinical performance, has been repeatedly proven effective in improving the quality of care. In 2004, Maccabi Healthcare Services (MHS), the second largest Israeli HMO, launched its Performance Measurement System (PMS) based on clinical quality indicators.

Introduction: The aim of this study was to evaluate the direct costs of patients with diabetes ensured in a large health maintenance organization, Maccabi Health Services (MHS), in order to compare the medical costs of these patients to the medical costs of other patients insured by MHS and to assess the impact of poorly controlled diabetes on medical costs.

Methods: A retrospective analysis of patients insured in MHS during 2012 was performed. Data were extracted automatically from the electronic database.

Background: In primary health care systems where member's turnover is relatively low, the question, whether investment in quality of care improvement can make a business case, or is cost effective, has not been fully answered.The objectives of this study were: (1) to investigate the relationship between improvement in selected measures of diabetes (type 2) care and patients' health outcomes; and (2) to estimate the association between improvement in performance and direct medical costs.

Methods: A time series study with three quality indicators - Hemoglobin A1c (HbA1c) testing, HbA1C and LDL- cholesterol (LDL-C) control - which were analyzed in patients with diabetes, insured by a large health fund.

Background: One of the major challenges health care systems face in modern time is treating chronic disorders. In recent years, the increasing occurrence of multiple chronic disorders (MCC) in single individuals has compounded the complexity of health care. In 2008, it was estimated that worldwide as many as one quarter of the population between the ages of sixty five to sixty nine suffered from two or more chronic conditions and this prevalence rose with age.

Background: The incidence of metabolic syndrome (MetS), diabetes mellitus (DM), and their coexistence is increasing but whether MetS increases cardiovascular risk beyond component risk factors is controversial.

Design: We compared the risk of cardiovascular death, myocardial infarction, or stroke among patients with MetS, newly detected DM, established DM, or coexistent MetS and DM in the global REduction of Atherothrombosis for Continued Health (REACH) registry.

Methods: Outpatients with or at risk for atherothrombosis were recruited between 1 December 2003 and 31 December 2004 and followed up to 4 years for cardiovascular events.

Although the beneficial effect of statins in secondary prevention of cardiac events is well established, their effectiveness in primary prevention is questionable when most evidence derives from randomized controlled trials and not "real-life" data. To evaluate the association between persistent use of statins and risk of acute nonfatal cardiovascular events in primary prevention patients in community settings, we retrospectively analyzed a cohort of 171,535 adults 45 to 75 years old with no indication of cardiovascular disease who began statin therapy from 1998 to 2009 in a large health maintenance organization in Israel. Persistence with statins was measured by the proportion of days covered with dispensed prescriptions of statins during the follow-up period.
