Multiple chronic disorders - health care system's modern challenge in the Maccabi Health Care System

Trends in antipsychotic treatment of children and adolescents in Israel from post-mental health reform to post-COVID19 pandemic (2015-2023)

This study investigates the patterns of antipsychotic drug dispensations among children and adolescents from 2015 to 2023, with a focus on the impact of introducing national health reform (2015) and the COVID-19 pandemic. Data from Maccabi Healthcare Services, encompassing 1,105,439 individuals aged 6-18 years, were analyzed using a retrospective cohort study. We investigated the incidence rates of antipsychotic prescriptions by age, sex, socioeconomic status, and geographical region. During the study period, there was a 15% overall increase in antipsychotics prescriptions. Higher prescription rates were observed among boys aged 6-11 years and girls aged 14-18 years. Significant increases in prescriptions were observed in the year immediately following the mental health reform and the COVID-19 pandemic. Low socioeconomic status and peripheral regions exhibited higher and increasing prescription rates. Seasonal patterns revealed peaks in the fourth quarter of each year. The study highlights an overall increase in antipsychotic prescriptions, influenced by policy changes and the pandemic. Inequality in prescription rates by socioeconomic status and geographical location underscores the need for targeted mental health interventions. The findings also suggest enduring changes in the utilization of antipsychotic medications among youth, which may reflect broader impacts of the COVID-19 pandemic on mental health care needs.

Responsibility of follow-up regarding medical recommendations in primary care and challenging patients: The perspective of doctors, nurses, pharmacists, and administrative staff

OBJECTIVE

This study examines the way healthcare staff describe challenging patients and perceive responsibility for follow-up of patients with chronic conditions.

METHODS

Interviews were conducted with 46 healthcare staff (15 primary care physicians/12 nurses/15 administrative staff/4 pharmacists) at 12 clinics in Israel. They were audiotaped, transcribed, and thematically analyzed using Atlas qualitative data analysis software.

RESULTS

Participants defined patients as "challenging" either because they are less likely to follow medical recommendations or are felt to overconsume care. Staff believed that patients did not follow medical recommendations because they were indifferent, unaware, in denial about deteriorating medical condition, or fear of the unknown. Participants generally perceived a shared responsibility for follow-up between the staff and the patient. Staff who endorsed closer relationships with staff members expressed empathy toward challenging patients and felt responsible for follow-up.

CONCLUSIONS

Healthcare staff perceive themselves as partially responsible for helping patients follow up with medical recommendations. Cohesive staff relationships may promote higher levels of empathy toward challenging patients and may contribute to helping patients follow up with recommended care. Practice implications To improve follow-up with medical recommendations, there is a need to develop and test interventions to promote more cohesive ties among clinic staff.

An empirical approach for life expectancy estimation based on survival analysis among a post-acute myocardial infarction population

Background

Practical communication of prognosis is pertinent in the clinical setting. Survival analysis techniques are standardly used in cohort studies; however, their results are not straightforward for interpretation as compared to the graspable notion of life expectancy (LE). The present study empirically examines the relationship between Cox regression coefficients (HRs), which reflect the relative risk of the investigated risk factors for mortality, and years of potential life lost (YPLL) values after acute myocardial infarction (AMI).

Methods

This retrospective population-based study included patients aged 40-80 years, who survived AMI hospitalization from January 1, 2002, to October 25, 2017. A survival analysis approach assessed relationships between variables and the risk for all-cause mortality in an up to 21-year follow-up period. The total score was calculated for each patient as the summation of the Cox regression coefficients (AdjHRs) values. Individual LE and YPLL were calculated. YPLL was assessed as a function of the total score.

Results

The cohort (n = 6316, age 63.0 ± 10.5 years, 73.4 % males) was randomly split into training (n = 4243) and validation (n = 2073) datasets. Sixteen main clinical risk factors for mortality were explored (total score of 0-14.2 points). After adjustment for age, sex and nationality, a one-point increase in the total score was associated with YPLL of ∼one year. A goodness-of-fit of the prediction model found 0.624 and 0.585 for the training and validation datasets respectively.

Conclusions

This functional derivation for converting coefficients of survival analysis into the comprehensible form of YPLL/LE allows for practical prognostic calculation and communication.

Identifying patients in need of palliative care: Adaptation of the Necesidades Paliativas CCOMS-ICO© (NECPAL) screening tool for use in Israel

OBJECTIVES

The Necesidades Paliativas CCOMS-ICO© (NECPAL) screening tool was developed to identify patients in need of palliative care and has been used in Israel without formal translation, reliability testing, or validation. Because cultural norms significantly affect subscales such as social vulnerability and health-care delivery, research is needed to comprehensively assess the NECPAL's components, adapt it, and validate it for an Israeli health-care setting. This study linguistically and culturally translated the NECPAL into Hebrew to examine cultural and contextual acceptability for use in the Israeli geriatric health sector. The newly adapted tool was measured for itemized and scale-level content validity, inter-rater reliability (IRR), and construct validity.

METHODS

The NECPAL was back-translated and its content validated by a 5-member expert panel for clarity and relevance, forming the Israeli-NECPAL (I-NECPAL). Six health-care professionals used the I-NECPAL with 25 post-acute geriatric patients to measure IRR. For construct validity, the known-groups method was used, as there is no "gold standard" method for identifying palliative needs for comparison with the NECPAL. The known groups were 2 fictitious cases, predetermined of palliative need. Thirty health-care professionals, blinded to the predetermined palliative status, used the I-NECPAL to determine whether a patient needs a palliative-centered plan of care.

RESULTS

The findings point to acceptable content and construct validity as well as IRR of the I-NECPAL for potential inclusion as a tool for identifying geriatric patients in need of palliative care. Content-validity assessment brought linguistic changes and the exclusion of the frailty parameter from the annex of chronic diseases. The kappa-adjusted scale-level content-validity index indicated a high level of content validity (0.96). IRR indicated a high level of agreement (all parameters with an "excellent-good" agreement level). The sensitivity (0.93), specificity (0.17), positive predictive value (0.53), and negative predictive value (0.71) revealed how heavily the scale weighed upon the surprise question. These metrics are improved when removing the surprise question from the instrument.

SIGNIFICANCE OF RESULTS

Similar to other countries, the Israeli health-care system is regulated by policies that portray the local beliefs and culture as well as evidence-based practice. The decision about when to switch a patient to a palliative-centered plan of care is one such example. It is thus of utmost importance that only locally adapted and vigorously tested screening tools be offered to health-care providers to assist in this decision. The I-NECPAL is the first psychometrically tested palliative needs identification tool for use in the geriatric population in Israel, on both a scale and an itemized level. The results indicate that it can immediately replace the current unvalidated version in use. Further research is needed to determine whether all parts of the scale are relevant for this patient population.

Real-World Data of Adherence and Drug Survival of Biologics in Treatment-Naïve and Treatment-experienced Adult Patients with Rheumatoid Arthritis

INTRODUCTION

Biologic disease-modifying anti-rheumatics drugs (bDMARDs) and targeted synthetic DMARDs (tsDMARDs) are important treatments for rheumatoid arthritis (RA). As more of these drugs become available, there is a greater need to assess their real-world adherence and drug survival.

METHODS

Treatment-naïve and treatment-experienced patients with RA who initiated treatment with bDMARDs and tofactinib during 2015-2018 in a large Israeli health maintenance organization were included. Adherence and time to treatment suspension were recorded. Odds for adherence were estimated using a multivariable logistic regression model. Risk for treatment suspension was estimated using a mixed-effect Cox proportional hazard model.

RESULTS

The analysis included 753 eligible patients (61.8% treatment-naïve) treated with 1287 treatment episodes (tofacitinib 24.2%, tocilizumab 17.5%, etanercept 16.0%, adalimumab 10.4%, abatacept 9.9%, rituximab 9.0%, golimumab 6.9%, certolizumab pegol 3.6%, infliximab 1.9%, and sarilumab 0.5%). Good adherence was measured for almost all drugs, yet over 50% of all treatment episodes were suspended. Older age was associated with reduced risk for treatment suspension while higher number of primary care visits and higher Charlson's comorbidity score were associated with increased risk. Compared to etanercept, treatment with adalimumab, certolizumab, or rituximab was associated with increased risk for treatment suspension (HR 1.68 95% CI 1.27-2.22, HR 1.62 95% CI 1.00-2.60, and HR 2.72 95% CI 2.02-3.67, respectively).

CONCLUSION

Treatment choice primarily depends on disease activity and prognosis. Real-world data, showing differences in drug survival of bDMARDs and tsDMARD, can also be used in the variety of considerations when choosing treatment. Future studies could separate patients with RA into subgroups, which would also account for potential drug survival differences and enable personalized therapy.

Greater temporal regularity of primary care visits was associated with reduced hospitalizations and mortality, even after controlling for continuity of care

BACKGROUND

Previous studies have shown that more temporally regular primary care visits are associated with improved patient outcomes.

OBJECTIVE

To examine the association of temporal regularity (TR) of primary care with hospitalizations and mortality in patients with chronic illnesses. Also, to identify threshold values for TR for predicting outcomes.

DESIGN

Retrospective cohort study.

PARTICIPANTS

We used data from the electronic health record of a health maintenance organization in Israel to study primary care visits of 70,095 patients age 40 + with one of three chronic conditions (diabetes mellitus, heart failure, chronic obstructive pulmonary disease).

MAIN MEASURES

We calculated TR for each patient during a two-year period (2016-2017), and divided patients into quintiles based on TR. Outcomes (hospitalization, death) were observed in 2018-2019. Covariates included the Bice-Boxerman continuity of care score, demographics, and comorbidities. We used multivariable logistic regression to examine TR's association with hospitalization and death, controlling for covariates.

KEY RESULTS

Compared to patients receiving the most regular care, patients receiving less regular care had increased odds of hospitalization and mortality, with a dose-response curve observed across quintiles (p for linear trend < 0.001). For example, patients with the least regular care had an adjusted odds ratio of 1.40 for all-cause mortality, compared to patients with the most regular care. Analyses stratified by age, sex, ethnic group, area-level SES, and certain comorbid conditions did not show strong differential associations of TR across groups.

CONCLUSIONS

We found an association between more temporally regular care in antecedent years and reduced hospitalization and mortality of patients with chronic illness in subsequent years, after controlling for covariates. There was no clear threshold value for temporal regularity; rather, more regular primary care appeared to be better across the entire range of the variable.

Long-Term Health Impacts of Wildfire Exposure: A Retrospective Study Exploring Hospitalization Dynamics Following the 2016 Wave of Fires in Israel

Background: Climate-related events, including wildfires, which adversely affect human health, are gaining the growing attention of public-health officials and researchers. Israel has experienced several disastrous fires, including the wave of fires in November 2016 that led to the evacuation of 75,000 people. The fires lasted six days (22–27 November) with no loss of life or significant immediate health impacts. The objective of this study is to explore the long-term hospitalization dynamics in a population exposed to this large-scale fire, including the effects of underlying morbidity and socio-economic status (SES). Methods: This is a retrospective crossover study, conducted in 2020, analyzing the electronic medical records of residents from areas exposed to a wildfire in northern Israel. The study spans from one year before exposure to two years after it (22 November 2015–27 November 2018). The hospitalization days during the study period were analyzed using the Poisson regression model. The rate of hospitalization days along with 95% confidence intervals (CIs) were plotted. Results: The study included 106,595 participants. The median age was 37 (IQR = 17–56), with a mean socio-economic ranking of 6.47 out of 10 (SD = 2.01). Analysis revealed that people with underlying morbidity were at greater risk of experiencing long-term effects following fires, which was manifested in higher hospitalization rates that remained elevated for two years post-exposure. This was also evident among individuals of low socio-economic status without these background illnesses. Conclusions: Healthcare services should prepare for increased hospitalization rates during the two years following wildfires for populations with underlying morbidity and those of low socio-economic status. Implementing preventive-medicine approaches may increase the resiliency of communities in the face of extreme climate-related events and prevent future health burdens. Additional research should focus on the specific mechanisms underpinning the long-term effects of wildfire exposure.

A platform for the international exchange of ideas: the Israel Journal of Health Policy Research celebrates its first decade

For ten years the Israel Journal of Health Policy Research has provided a platform for exchange of knowledge and insights on health policy. It is a unique attempt by scholars and practitioners in one small country to share their knowledge with the world and, in turn to learn from experience elsewhere. Never has this role been as important as during the COVID pandemic, a message that is very clear when we look at failings elsewhere.

Diabetes associated risk for mortality increases with time among first stroke survivors - Findings from the Israeli National Stroke Registry

BACKGROUND

Diabetes is a major risk factor for ischemic stroke and may affect post-stroke survival. Previous large scale studies of long-term post-stroke survival are limited and most of them excluded older patients from the study population.

OBJECTIVES

To compare the risk factors and sociodemographic characteristics between first ischemic stroke cases with and without diabetes and to assess the mortality risk associated with diabetes.

METHODS

Using population-based National Stroke Registry in Israel, all patients hospitalized for a first event of ischemic stroke between the years 2014-2018 were followed for all-cause mortality. Chi-square analysis was used to compare the differences in risk factors, sociodemographic profile and cumulative mortality between patients with and without diabetes. Cox proportional hazards models were used to estimate the hazard ratio for mortality in selected timeframes.

RESULTS

Among 41,639 patients with a first event of ischemic stroke, 44.5% were previously diagnosed with diabetes. Diabetic patients were more likely to be males, members of the Arab ethnic group, with lower socioeconomic status and a higher prevalence of cardiovascular comorbidities, anemia, leukocytosis and abnormal kidney function. Diabetes was associated with a higher mortality risk in the first year and long term, but not in the first month following stroke. Diabetes-associated mortality risk interacted with time and age, was higher in younger age and increased with time.

CONCLUSIONS

Our findings suggest that diabetes is associated with a higher prevalence of comorbidities among patients with first ischemic stroke and with a higher risk for mortality in the mid and long term, which is more profound in younger age.

Household and area-level social determinants of multimorbidity: a systematic review

BACKGROUND

No clear synthesis of evidence examining household and area-level social determinants of multimorbidity exists. This study aimed to systematically review the existing literature on associations between household and area-level social determinants of health (SDoH) and multimorbidity prevalence or incidence in the general population.

METHODS

Six databases (MedLine, EMBASE, PsychINFO, Web of Science, CINAHL Plus and Scopus) were searched. The search was limited to peer-reviewed studies conducted in high-income countries and published in English between 2010 and 2019. A second reviewer screened all titles with abstracts and a subset of full texts. Study quality was assessed and protocol pre-registered (CRD42019135281).

RESULTS

41 studies spanning North America, Europe and Australasia were included. Household income and area-level deprivation were the most explored with fairly consistent findings. The odds of multimorbidity were up to 4.4 times higher for participants with the lowest level of income compared with the highest level. Those living in the most deprived areas had the highest prevalence or incidence of multimorbidity (pooled OR 1.42, 95% CI 1.41 to 1.42). Associations between deprivation and multimorbidity differed by age and multimorbidity type. Findings from the few studies investigating household tenure, household composition and area-level rurality were mixed and contradictory; homeownership and rurality were associated with increased and decreased multimorbidity, while living alone was found to be associated with a higher risk of multimorbidity and not associated.

CONCLUSION

Improving our understanding of broader social determinants of multimorbidity-particularly at the household level-could help inform strategies to tackle multimorbidity.

Definitions and Prevalence of Multimorbidity in Large Database Studies: A Scoping Review

BACKGROUND

Multimorbidity presents a key challenge to healthcare systems globally. However, heterogeneity in the definition of multimorbidity and design of epidemiological studies results in difficulty in comparing multimorbidity studies. This scoping review aimed to describe multimorbidity prevalence in studies using large datasets and report the differences in multimorbidity definition and study design.

METHODS

We conducted a systematic search of MEDLINE, EMBASE, and CINAHL databases to identify large epidemiological studies on multimorbidity. We used the Preferred Reporting Items for Systematic Reviews and Meta-analysis Extension for Scoping Reviews (PRISMA-ScR) protocol for reporting the results.

RESULTS

Twenty articles were identified. We found two key definitions of multimorbidity: at least two (MM2+) or at least three (MM3+) chronic conditions. The prevalence of multimorbidity MM2+ ranged from 15.3% to 93.1%, and 11.8% to 89.7% in MM3+. The number of chronic conditions used by the articles ranged from 15 to 147, which were organized into 21 body system categories. There were seventeen cross-sectional studies and three retrospective cohort studies, and four diagnosis coding systems were used.

CONCLUSIONS

We found a wide range in reported prevalence, definition, and conduct of multimorbidity studies. Obtaining consensus in these areas will facilitate better understanding of the magnitude and epidemiology of multimorbidity.

Multimorbidity and quality of life: Systematic literature review and meta-analysis

Multimorbidity is typically defined as the co-existence of two or more chronic diseases within an individual. Its prevalence is highest among the elderly, with poor quality of life (QoL) being one of the major consequences. This study aims to: (1) understand the relationship between multimorbidity and QoL or health-related quality of life (HRQoL) through systematic literature review; (2) explore the strength of this association by conducting the first meta-analysis on the subject. Following PRISMA, Medline/PubMed, Embase, CINAHL and PsycINFO were searched for studies published through September 1st, 2018. Original studies with clear operationalization of multimorbidity and validated QoL (or HRQoL) measurement were retained. For random-effect meta-analysis, a minimum of three studies with the same multimorbidity tool (e.g. number of diseases or equal comorbidity index) and the same QoL tool were required. Number of diseases was most common and the only measure on which meta-analysis was carried out. The outcome of interest was the linear regression slope between increasing number of diseases and QoL. Heterogeneity was explored with meta-regression. Out of 25,890 studies initially identified, 74 studies were retained for systematic review (total of 2,500,772 participants), of which 39 were included in the meta-analysis. The mean decrease in HRQoL per each added disease, depending on the scale, ranged from: -1.55% (95%CI: -2.97%, -0.13%) for the mental component summary score of pooled SF-36, -12 and -8 scales to -4.37% (95%CI: -7.13%, -1.61%) for WHOQoL-BREF physical health domain. Additional studies considering severity, duration and patterns of diseases are required to further clarify this association.

The quality of primary care provided to the elderly in Israel

BACKGROUND

In view of increasing global and local trends in population ageing and the high healthcare utilization rates among the elderly, this study assesses the quality of primary care provided to the elderly population in Israel. It examines changes in quality over time, how quality varies across sub-groups of the elderly, and how quality in Israel compares with other countries. Data originate from the National Program for Quality Indicators in Community Healthcare (QICH), which operates in full collaboration with Israel's four HMOs.

METHODS

The study population included all elderly Israeli residents aged 65 years or older during 2002-2015 (N = 879,671 residents in 2015). Seven elderly-specific quality indicators from within the QICH framework were included: influenza and pneumococcal vaccinations, benzodiazepine overuse, long-acting benzodiazepine use, body weight documentation, weight loss and underweight. In addition, two non-age specific quality indicators relating to diabetes mellitus were included: the rate of HbA1C documentation and uncontrolled diabetes. Data were collected from patient electronic medical records (EMR) in accordance with each HMO, and aggregated by three variables: gender, age, and socio-economic position (SEP).

RESULTS

During the measurement period, vaccination rates significantly increased (Influenza: from 42.0% in 2002 to 63.2% in 2015; and pneumococcal vaccination: from 25.8% in 2005 to 77.0% in 2015). Body weight documentation (in 65-74 year old persons) increased from only 16.3% in 2003 to 80.9% in 2015. The rate of underweight (BMI < 23 kg/m2) and significant weight-loss (10% or more of their body weight) was only measured in 2015. The overall rate of benzodiazepine overuse remained steady from 2011 to 2015 at around 5%, while the rate of long-acting benzodiazepine use decreased from 3.8% in 2011 to 2.4% in 2015. The rate of HbA1c documentation for elderly diabetics was higher than for non-elderly diabetics in 2015 (92.2% vs 87.9%). The rate of uncontrolled diabetes was lower for the elderly than the non-elderly population in 2015 (6.9% vs. 15.7%). Gender disparities were observed across all measures, after age stratification, with worse indicator rates among females compared to males. SEP-disparities were not consistent across measures. In all indicators except benzodiazepine overuse, Israel showed a higher quality of care for the elderly in comparison with the international healthcare community.

CONCLUSIONS

Overall, the quality of care received by elderly Israelis has improved substantially since measurements first began; yet, females receive lower quality care than males. Monitoring results of primary care quality indicators can contribute to population's successful aging; both chronic conditions at earlier ages (e.g. diabetes), and short-term hazardous conditions such as the use of potentially harmful medications and weight loss should be evaluated.

Targeted approaches to improve outcomes for highest-cost patients

Bash and colleagues, using data from Maccabi Healthcare Services, have documented increased cost and utilization attributable to patients with congestive heart failure (CHF). The CHF patients were older than the general population and had high rates of important comorbid conditions. While it is somewhat predictable that such a population would have higher healthcare utilization and costs, the extent of the difference was still surprising. Most CHF patients (78%) were hospitalized at least once, compared to only 21% of patients without CHF. CHF patients used dramatically more of every kind of health care, including physician visits, emergency department visits, and specialty care visits. In this paper, Bash and colleagues have provided essential information about the “cost epidemiology” of CHF patients in the Israeli context.

This commentary places these results in a broader context of how “cost epidemiology” information can be translated into targeted programs to improve outcomes and costs for vulnerable populations. The commentary makes three key points. First, beyond showing the increased utilization and cost attributable to CHF, there is also a need to examine which patients within this broad category contribute most to these increased costs, and might therefore be targeted for enhanced services. Second, it is helpful to make a business case for intervening to improve outcomes with a subpopulation, focusing in particular on the return on investment from the standpoint of the payer. Finally, while Israeli health collectives have already deployed programs to improve outcomes in older and sicker patients, there may be a need to more precisely define important subpopulations based on social risk factors or particularly severe disease manifestations, and then target those subpopulations with tailored programs focused on their particular needs.

A Chinese version of the Patient Continuity of Care Questionnaire: reliability and validity assessment

AIMS AND OBJECTIVES

To examine the psychometric properties of the Chinese version of Patient Continuity of Care Questionnaire (PCCQ) to see whether the Patient Continuity of Care Questionnaire can be applied in Chinese context.

BACKGROUND

The rapid increase in the number of older adults with chronic diseases has made caring for this vulnerable population a priority healthcare issue in Taiwan. The PCCQ has been widely used in international studies. However, research has not yet assessed the suitability and applicability of the PCCQ in Taiwan.

DESIGN

A cross-sectional survey design was applied for the psychometric testing of the scale.

METHODS

A total of 314 older Taiwanese adults with chronic diseases receiving discharge planning intervention were pooled from a hospital in Central Taiwan. After receiving permission from the author of the PCCQ, a Chinese translation and back translation were made.

RESULTS

The scale was first rated by eleven experts with a Content Validity Index of 0·93. Two factors were extracted with the exploratory factor analysis, namely 'information transfer to patients' and 'relationships with providers during hospitalisation', with a total of 70·34% of the variance explained.

CONCLUSIONS

The PCCQ - Chinese can be used to assist professionals to fully understand the continuity of care of the discharged patients under consideration.

RELEVANCE TO CLINICAL PRACTICE

A PCCQ - Chinese version can be used as a guide for discharging preparation that enables patients to receive high-quality continuity of care and further to self-manage their conditions.

Prevalence and Losses in Quality-Adjusted Life Years of Child Health Conditions: A Burden of Disease Analysis

OBJECTIVES

To estimate the prevalence and losses in quality-adjusted life years (QALYs) associated with 20 child health conditions.

METHODS

Using data from the 2009-2010 National Survey of Children with Special Health Care Needs, preference weights were applied to 14 functional difficulties to summarize the quality of life burden of 20 health conditions.

RESULTS

Among the 14 functional difficulties, "a little trouble with breathing" had the highest prevalence (37.1 %), but amounted to a loss of just 0.16 QALYs from the perspective of US adults. Though less prevalent, "a lot of behavioral problems" and "chronic pain" were associated with the greatest losses (1.86 and 3.43 QALYs). Among the 20 conditions, allergies and asthma were the most prevalent but were associated with the least burden. Muscular dystrophy and cerebral palsy were among the least prevalent and most burdensome. Furthermore, a scatterplot shows the association between condition prevalence and burden.

CONCLUSIONS

In child health, condition prevalence is negatively associated with quality of life burden from the perspective of US adults. Both should be considered carefully when evaluating the appropriate role for public health prevention and interventions.

Policy issues related to educating the future Israeli medical workforce: an international perspective

A 2014 external review of medical schools in Israel identified several issues of importance to the nation's health. This paper focuses on three inter-related policy-relevant topics: planning the physician and healthcare workforce to meet the needs of Israel's population in the 21(st) century; enhancing the coordination and efficiency of medical education across the continuum of education and training; and the financing of medical education. All three involve both education and health care delivery. The physician workforce is aging and will need to be replenished. Several physician specialties have been in short supply, and some are being addressed through incentive programs. Israel's needs for primary care clinicians are increasing due to growth and aging of the population and to the increasing prevalence of chronic conditions at all ages. Attention to the structure and content of both undergraduate and graduate medical education and to aligning incentives will be required to address current and projected workforce shortage areas. Effective workforce planning depends upon data that can inform the development of appropriate policies and on recognition of the time lag between developing such policies and seeing the results of their implementation. The preclinical and clinical phases of Israeli undergraduate medical education (medical school), the mandatory rotating internship (stáge), and graduate medical education (residency) are conducted as separate "silos" and not well coordinated. The content of basic science education should be relevant to clinical medicine and research. It should stimulate inquiry, scholarship, and lifelong learning. Clinical exposures should begin early and be as hands-on as possible. Medical students and residents should acquire specific competencies. With an increasing shift of medical care from hospitals to ambulatory settings, development of ambulatory teachers and learning environments is increasingly important. Objectives such as these will require development of new policies. Undergraduate medical education (UME) in Israel is financed primarily through universities, and they receive funds through VATAT, an education-related entity. The integration of basic science and clinical education, development of earlier, more hands-on clinical experiences, and increased ambulatory and community-based medical education will demand new funding and operating partnerships between the universities and the health care delivery system. Additional financing policies will be needed to ensure the appropriate infrastructure and support for both educators and learners. If Israel develops collaborations between various government agencies such as the Ministries of Education, Health, and Finance, the universities, hospitals, and the sick funds (HMOs), it should be able to address successfully the challenges of the 21st century for the health professions and meet its population's needs.

High performance team-based care for persons with chronic conditions

Care for patients with complex chronic conditions such as diabetes requires a coordinated and collaborative team working in partnership with the patient. Israel has taken important steps forward with the development of structured diabetes follow-up by Clalit Health Services, including several measures of diabetes care in the National Program for Quality Indicators in Community Healthcare, and efforts to develop health information exchange and measures of continuity between hospital and community-based care. Achieving even better results will require purposeful development of health care teams to meet the needs of patients with single and multiple chronic conditions, including robust interprofessional education programs for the next generation of health professionals, and developing partnerships between the teams and the patients.

The challenge of measuring multi-morbidity and its costs

The ageing of the population across developed countries and beyond has increased the importance of examining multi-morbidity. The recent paper by Arbelle et al. [Isr J of Health Policy Res. 2014;3:29] on multiple chronic conditions in Israel's Maccabi Health Care System (MHC) is a welcome and interesting contribution to the literature on this topic. They found that the prevalence of multiple chronic conditions among the MHC population rises with age, is lower for higher socioeconomic groups, and is higher than in a primary care population in Scotland studied by Barnett et al. [Lancet. 2012;380:37-43]. The difference in prevalence between the two studies is unlikely to reflect entirely, or probably even mainly, real differences in morbidity rates between the two countries. Systematic reviews have highlighted large differences in the prevalence of multi-morbidity in different studies. Although the Israeli and Scottish study used similar definitions and methods, the nature of the source data differed. It seems likely that the incentives to record the full range of patients' conditions may differ between data sources depending on the uses of the data, which may in turn depend on the country's health care financing system. If this is correct, it will complicate comparisons between different jurisdictions. It is important to consider not only the prevalence of multi-morbidity but also its costs to the health system and to wider society. Cost of illness studies can be helpful in informing decisions about prioritisation of resources. Multi-morbidity complicates such studies. The overall costs of health and social care for people with a specific condition would include costs relating to any comorbidities. To examine the marginal impact on overall costs of each condition among those with multiple conditions is likely to be complex and arguably not especially useful.
