BackgroundThe age-adjusted mortality rate in Israel is low compared to most Western countries although mortality rates from diabetes and renal failure in Israel are amongst the highest, while those from cardiovascular diseases (CVD) are amongst the lowest. This study aims to assess validity of choice of underlying causes (UC) in Israel by analyzing Israeli and international data on the prevalence of these diseases as multiple causes of death (MCOD) compared to UC, and data on comorbidity (MCOD based).MethodsAge-adjusted death rates were calculated for UC and MCOD and the corresponding ratio of multiple to underlying cause of death (SRMU) for available years between 1999 and 2012. Comorbidity was explored by calculating cause of death association indicators (CDAI) and frequency of comorbid disease. These results were compared to data from USA, France, Italy, Australia and the Czech Republic for 2009 or other available year.ResultsMortality rates for all these diseases except renal failure have decreased in Israel between 1999 and 2012 as UC and MCOD. In 2009, the SRMU for diabetes was 2.7, slightly lower than other Western countries (3.0–3.5) showing more frequent choice as UC. Similar results were found for renal failure. In contrast, the SRMU for ischemic heart disease (IHD) and cerebrovascular disease were 2.0 and 2.6, respectively, higher than other countries (1.4–1.6 and 1.7–1.9, respectively), showing less frequent choice as UC. CDAI data showed a strong association between heart and cerebrovascular disease, and diabetes in all countries. In Israel, 40 % of deaths with UC diabetes had IHD and 24 % had cerebrovascular disease. Renal disease was less strongly associated with IHD.ConclusionThis international comparison suggests that diabetes and renal failure may be coded more frequently in Israel as UC, sometimes instead of heart and cerebrovascular disease. Even with some changes in coding, mortality rates would be high compared to other countries, similar to the comparatively high diabetes prevalence in Israel at older ages and high rate of end-stage renal failure.This study highlights the importance of physician training on death certification practice and need for further progress towards automation in recording and coding death causes.Electronic supplementary materialThe online version of this article (doi:10.1186/s13584-015-0027-6) contains supplementary material, which is available to authorized users.
BackgroundMedical practice variation refers to differences in health service utilization among regions in the same country. It is used as a tool for studying health inequities.In 2011, the OECD launched a Medical Practice Variation Project which examines regional differences within countries and explores the sources of the inter-regional differences. The aim of this study is to examine the patterns and trends in geographic variation for selected health services in Israel.MethodsThe analysis is based on data from the National Hospital Discharges Database (NHDD) of the Israeli Ministry of Health. The eight procedures and services studied were: medical admissions (i.e. admissions without surgical procedures); hip fractures; caesarian sections; diagnostic cardiac catheterization; cardiac angioplasty (PTCA); cardiac bypass surgery (CABG); hysterectomy; and knee replacement surgery. The data are presented for the 7 districts in Israel, determined by address of residence.ResultsThe procedures and services with the lowest variation across the seven districts were medical admissions (RR between regions-maximum/minimum 1.3) and hip fractures (RR 1.44), while the one with the highest variation was CABG (RR 1.98). The Israeli periphery, and the northern district in particular, had higher rates of medical admissions, knee replacement and cardiac procedures. When studying the trend over time, we found a decrease in use rates for most procedures, such as coronary bypass (R. 04) and CABG (R 0.8). Medical admissions decreased by 8%, with the highest decline (16%) observed in the central districts.ConclusionsThis study provides Israeli policy makers with information which is vital for the strategic planning of service development, such as strengthening preventive medical services in the community, reducing cardiovascular risk factors in the periphery and expanding the national publication of clinical quality scores.Electronic supplementary materialThe online version of this article (doi:10.1186/s13584-016-0127-y) contains supplementary material, which is available to authorized users.
Hospital burden in pediatric and internal medicine departments during influenza seasons in Israel was associated with age and diagnosis. These results are important for optimal preparedness for influenza seasons.
BackgroundRegional variations in mortality can be used to study and assess differences in disease prevalence and factors leading to disease and mortality from different causes. To enable this comparison, it is important to standardize the mortality data to adjust for the effects of regional population differences in age, nationality and country of origin.MethodsStandardized mortality ratios (SMR) were calculated for the districts and sub-districts in Israel, for total mortality by gender as well as for leading causes of death and selected specific causes. Correlations were assessed between these SMRs, regional disease risk factors and socio-economic characteristics. Implications for health policy were then examined.ResultsTotal mortality in the Northern District of Israel was not significantly different from the national average; but the Haifa, Tel Aviv, and Southern districts were significantly higher and the Jerusalem, Central, Judea and Samaria districts were lower.Cancer SMR was significantly lower in Jerusalem and not significantly higher in any region. Heart disease and diabetes SMRs were significantly higher in many sub-districts in the north of the country and lower in the south. SMRs for septicemia, influenza/pneumonia, and for cerebrovascular disease were higher in the south. Septicemia was also significantly higher in Tel Aviv and lower in the North, Haifa and Jerusalem districts. SMRs for accidents, particularly for motor vehicle accidents were significantly higher in the peripheral Zefat and Be’er Sheva sub-districts.ConclusionThe SMR, adjusted for age and ethnicity, is a good method for identifying districts that differ significantly from the national average. Some of the regional differences may be attributed to differences in the completion of death certificates. This needs to be addressed by efforts to improve reporting of causes of death, by educating physicians.The relatively low differences found after adjustment, show that factors associated with ethnicity may affect mortality more than regional factors. Recommendations include encouraging good eating habits, exercise, cancer screening, control of hypertension, reduction of smoking and improving road infrastructure and emergency care access in the periphery.Electronic supplementary materialThe online version of this article (doi:10.1186/s13584-017-0164-1) contains supplementary material, which is available to authorized users.
Background People with severe mental disorders have higher mortality rates and more chronic physical conditions than the general population. Recent reforms in the Israeli mental health system included reducing the number of psychiatric hospital beds (“Structural Reform”), establishing community- based rehabilitation services (“Rehabilitation Reform”), and the transfer of governmental responsibility to the Health Maintenance Organizations (HMOs) (“Insurance Reform”). We examined how these changes have impacted the physical health of people with severe mental illness as reflected in acute care hospitalizations. Methods Data from the National Psychiatric Case Register were linked with data from the National Hospital Discharges Database for 2000–2019. Acute care discharges from public hospitals were identified for people who had a psychiatric hospitalization with a diagnosis of severe mental illness (SMI, ICD-10 codes F10-F69 or F90-F99) within the preceding 5 years. The discharge rate of SMI patients was compared to that of the total population by age, diagnosis group, and period of hospitalization. Total and age-standardized discharge ratios (SDR) were calculated, using indirect standardization. Results The SDR for total acute care hospitalizations showed that discharge rates in 2016–2019 were 2.7 times higher for the SMI population than expected from the total population. The highest SDR was for external causes (5.7), followed by respiratory diseases (4.4), infectious diseases (3.9), skin diseases (3.7) and diabetes (3.3). The lowest SDR was for cancer (1.6). The total discharge rate ratio was lowest at ages 65–74 (2.2) and highest at ages 45–54 (3.2). The SDR was lowest for females at ages 25–34 (2.1) and for males at ages 18–24 (2.3). SDRs increased over the study period for all diagnoses. This increasing trend slowed at the end of the period, and between 2012–2015 and 2016–2019 there was a small decrease for skin and liver diseases, the SDR was stable for cancer and the increase was smaller for respiratory, infectious and circulatory diseases and diabetes. Conclusion This study showed higher hospitalization rates in people with SMI compared to the total population. These differences increased between 2000 and 2019 following the opening of alternative services in the community, possibly due to a higher likelihood of psychiatric hospitalization only for those with more severe mental disease. We recommend that general practitioners and mental health professionals in the community be made aware of the essential importance of good physical healthcare, and collaborate on health promotion and disease prevention in the SMI population.
