Patients' and physicians' characteristics associated with the purchase of benzodiazepines by older primary care patients in Israel.

This study evaluated patients' and physicians' characteristics associated with the purchase of benzodiazepines by older primary care patients in Israel. The analytic sample consists of those 6,421 patients age 65 and older. We used multi-level analysis with whether or not benzodiazepines were purchased at least once between June 2005 and 2007 as an outcome. We also evaluated patients' and physicians' characteristics associated with the purchase of benzodiazepines for 6 months or longer. Almost half the sample (41.5%) purchased benzodiazepines at least once during the study period and more than half (54.5%) of those purchasing benzodiazepines had a continued purchase for 6 months or longer. Physicians' characteristics explained only a small portion of the variance associated with purchasing, whereas patients' demographic and clinical characteristics were associated with purchasing. Any intervention to improve the use of benzodiazepines should be directed at both patients and physicians.

Integrating CAM and biomedicine in primary care settings: physicians' perspectives on boundaries and boundary work.

In this article, we present the results of a study that was conducted among 15 family physicians who had incorporated complementary and alternative medicine (CAM) into their clinical work in Israel. We aimed to explore the types of boundaries those physicians encountered, how these boundaries were contoured, and under what circumstances they were crossed. We conducted in-depth interviews with the physicians in 2008, and found that epistemological and cognitive boundaries did not pose a problem for them. However, with regard to the organizational boundary, the participants indicated that it was necessary to use a variety of strategies before they could utilize their CAM skills. Many of the participants indicated that the epistemological differences between the biomedical and CAM paradigms, such as the absence of evidence-based medicine in CAM practices, are not important. The ease with which boundaries were crossed in the complex social context described here is characteristic of postmodern societies. On the whole, the integrative physicians interviewed can be viewed as "postmodern" professionals who reject the impermeability of many long-established boundaries and hierarchies.

When co-payments for physician visits can affect supply as well as demand: findings from a natural experiment in Israel's national health insurance system.

In 1998, Israel's national health insurance system introduced a modest co-payment for visits to specialist physicians. This study takes advantage of a natural experiment in which 15% of the population--the poor and disabled--was exempted from these co-payments. It used the micro-level panel data of three large health plans on the physician visits of 50,000 members per plan in 1997-2001. The data indicate that, following introduction of the co-payment, specialist visits increased among non-exempt members, relative to exempt members, of two health plans that together account for two-thirds of the population. This paper illustrates how, unlike the Health Insurance Experiment and other US studies of cost sharing, the structure of the co-payment in Israel may have inadvertently limited the incentive to decrease consumer demand and may have created an incentive for the health plans to increase visit rates, especially among the non-exempt members. Other countries that have implemented co-payment systems with exemptions may benefit from the Israeli experience in designing and evaluating their systems.

Factors associated with hypertensive patients' compliance with recommended lifestyle behaviors.

BACKGROUND: A crucial element in controlling blood pressure is non-pharmaceutical treatment. However, only a few studies specifically address the question of hypertensive patients' compliance with physicians' recommendations for a healthy lifestyle. OBJECTIVES: To explore factors associated with hypertensive patients' compliance with lifestyle recommendations regarding physical activity, smoking cessation and proper diet. METHODS: We performed a secondary data analysis of a representative sample of 1125 hypertensive patients in Israel's two largest health funds. Data were collected in 2002-2003 by telephone interviews using structured questionnaires. The response rate was 77%. Bivariate and multivariate analysis was conducted. RESULTS: About half of the hypertensive patients reported doing regular exercise and adhering to a special diet; 13% were smokers. About half reported receiving counseling on smoking cessation and diet and a third on physical exercise. A quarter reported receiving explanations regarding self-measurement of blood pressure and signs of deterioration. Multivariate analysis revealed that patients' beliefs about hypertension management, their knowledge on hypertension and its management, and physician counseling on a healthy lifestyle and self-care, have an independent effect on compliance with recommended lifestyle behaviors. CONCLUSIONS: The low counseling rates suggest that there may be a need to improve physicians' counseling skills so that they will be more confident and effective in delivering this service to their patients. A model based on educating both physicians and patients may contribute to improving the care of hypertensive patients.

Teamwork in treating diabetes and hypertension in Israeli managed care organizations.

PURPOSE: This article aims to analyze existing and preferred labor divisions between physicians and nurses treating patients with hypertension and diabetes in managed care organizations. DESIGN/METHODOLOGY/APPROACH: A mail survey was conducted in 2002/2003 among a representative sample of 743 physicians employed by Israel's largest managed care health plans (78 percent response rate). A telephone survey among a representative sample of 1,369 hypertensive or diabetic patients (77 percent response rate) was also used. FINDINGS: Findings reveal a conspicuous gap between actual labor division and what physicians perceive to be ideal. Possible reasons for this gap are discussed and strategies for facilitating collaboration, which would improve service quality as well as work life quality for both physicians and nurses. ORIGINALITY/VALUE: This study provides empirical data on the extent of nurse involvement in managed care organization chronic patient care, as well as comparing them to physicians' preferences regarding nurse involvement.

The Israeli mental health insurance reform--perspectives.

BACKGROUND: At present, Israel's mental health system functions separately from its physical health system in terms of financing, planning, organization and practice setting. The government is responsible for the provision of mental health care, while the country's four, competing, non-profit health plans are responsible for physical health care. A reform effort is underway to transfer legal responsibility for the provision of mental health care from the government to the health plans. AIMS: The main objectives of this paper are to summarize the key components of the reform, its objectives, and the concerns that it has raised. The paper also seeks to foster interactions between experts from Israel and other countries about the Israeli reform. METHODS: The analysis is based on official government documents, the scholarly literature about the Israeli reform and the relevant international literature about mental health care in other countries, participation in key public meetings related to the reform, discussions with leaders of the reform effort, and discussions with leading mental health experts in other countries. RESULTS: Two elements of the reform--the application of managed care principles to mental health and the integration of mental and physical care--are shown to be central both to the reform's objectives and to the concerns that have been raised about the reform. DISCUSSION: These same two elements are relevant to many countries implementing or considering reforms in their mental health systems. CONCLUSIONS: The architects of the Israeli reform could learn a great deal from the experience with mental health care and related reforms in other countries. At the same time, the Israeli reform could offer important insights and lessons for other countries. IMPLICATIONS FOR POLICY: The Government of Israel should work with the international mental health care professional community to create frameworks that would facilitate cross-national learning. IMPLICATIONS FOR FURTHER RESEARCH: It will be important to monitor the implementation of the reform and evaluate its impact, in order to assess the extent to which the objectives are met and the extent to which the concerns materialize. Cross-national research collaborations could be very helpful.

Implementing QA programs in managed care health plans: factors contributing to success.

PURPOSE: The purpose of this paper is to identify the factors that contribute to the success or failure of quality assurance programs implemented by Israeli managed care health plans. DESIGN/METHODOLOGY/APPROACH: An in-depth study of seven quality assurance programs was conducted, comparing successful with unsuccessful ones using the comparative "case study" method. Employing a semi-structured questionnaire, 42 program directors and professionals in the field were interviewed. FINDINGS: A number of factors associated with the programs' success emerged. Those external to the program included: ongoing management support, resource allocation, information system support and perceived financial benefit for the organization. Internal factors included: leadership, perceived problem's importance, laying the groundwork in the field, involving field staff in planning and implementation and staff motivation. ORIGINALITY/VALUE: The study provides insights into ways to encourage the implementation of successful quality assurance programs in the special organizational context of managed care health plans. As the implementation relies heavily on data, one important precondition is the development of computerized information systems to facilitate ongoing data collection. It is also necessary from the planning stage to take into account organizational factors that affect success.

Pay-for-performance programs in P4P programs Israeli sick funds.

PURPOSE: This paper aims to analyze the development of "pay-for-performance" (P4P) programs implemented by Israel's two largest sick funds, insuring 78 percent of the population. DESIGN/METHODOLOGY/APPROACH: Analysis of the main features and their evolution over time, the observed outcomes and concerns related to implementing these programs. FINDINGS: Our analysis revealed that although implementation has been successful, both managers and physicians have voiced concerns regarding the effect of measuring clinical performance such as focusing attention on the measured areas while neglecting other areas, and motivating a statistical approach to patient care instead of providing patient-centered care. ORIGINALITY/VALUE: The Israeli case provides an interesting example of nation-wide, long-term implementation of the pay-for-performance program. Therefore, it provides other countries with the opportunity to assess features that may facilitate successful implementation, as well as highlighting issues related to the outcomes of P4P programs.

Factors affecting primary care physicians' perceptions of health system reform in Israel: professional autonomy versus organizational affiliation.

This paper examines primary care physicians' perceptions of a National Health Insurance Law that introduced managed competition into Israel's health care system, and the factors affecting their perceptions. Between April and July 1997, we conducted a mail survey of primary care physicians employed by Israel's four health plans (which are managed care organizations). Eight hundred questionnaires were returned, representing a response rate of 86%. The findings indicate that, overall most physicians support the components of the National Health Insurance Law with statistically significant differences among physicians by health plan. Multivariate analysis revealed that, contrary to theoretical expectations, a perceived decrease in professional autonomy and in the status of the profession following reform did not significantly affect attitudes toward national health insurance. These findings highlight the need for additional empirical studies to further examine theoretical contentions about the implications of infringing on the professional autonomy and the dominant status of physicians. The principal and most interesting finding of this study was the independent effect of health plan affiliation on physicians' attitudes toward each of the five components of the National Health Insurance Law, after controlling for background characteristics, for the reform's perceived effect on the physicians' autonomy and status in the health plan, and for the reform's perceived effect on the level of health plan services and the health plan's financial situation. We found that physicians' perceptions tended to conform to the formal position of their health plan, suggesting the need to analyze the attitudes of physicians in their organizational context, rather than treating them as members of a uniform professional community.

The effect of commitment to the organization on physicians' familiarity with guidelines for diabetes in managed care organizations.

Despite continuous efforts, healthcare organizations still find it difficult to influence physicians to follow clinical guidelines. Previous studies have not taken into account the organizational context of the physicians' practice. We conducted a survey of a representative sample of 743 primary care physicians employed in Israel's 2 largest managed care health plans. The findings indicated that "commitment to the health plan" and "perceived monitoring by the health plan" had an independent positive effect on familiarity with guidelines for treating diabetes. We propose that managers of healthcare organizations consider enhancing physicians' commitment to the organization as a means for increasing their adherence with clinical guidelines, thereby improving the quality of care provided to diabetic patients.

Responses of Israeli HMOs to environmental change following the National Health Insurance Law: Opening the black box.

Managed competition was introduced into the Israeli health care system with the enactment of the National Health Insurance (NHI) Law of 1995, which radically transformed health management organizations' (HMO) regulatory and competitive environments. We conducted an in-depth, qualitative analysis of the strategies developed by two Israeli HMOs in response to this change, and developed the concept of a "strategic repertoire" to integrate diverse theories of organizational adaptation to environmental change. Although the responses of these organizations to managed competition were broadly comparable, they diverged from one another in important ways. Our analysis highlights how the interaction among organizational history, managerial choice, and environmental constraints creates divergence in organizational responses to national policy initiatives. Policy implications arising from the findings include ways of anticipating unintended consequences of policy initiatives, such as involving provider organizations in the structuring of reform, or simulating their response in advance, based on expert knowledge of their strategic repertoires; and the need to include mechanisms for obtaining feedback on organizational responses in the implementation of reform. This will facilitate the adjustment of program regulations and incentives in response to emerging practices.

Evaluating the effect of regulatory prohibitions against risk selection by health status on supplemental insurance ownership in Israel.

In Israel, supplemental insurance, which covers services not included in the mandatory basic benefits package, is offered by sick funds and regulated by the Ministry of Health. In 1998, policy regulations were set to eliminate barriers that prevented the ill from purchasing supplemental insurance, thereby increasing equality and risk solidarity. In this paper, we examine whether these regulations have indeed changed the extent of ownership and characteristics of policyholders, using data from surveys conducted in 1995, 1997, 1999, and 2001. The findings indicate that while there were no significant changes between 1995 and 1997, there was a significant increase in ownership among those with poor health status after the new regulations came into effect. We conclude that administrative regulations can influence the structure of supplemental insurance to achieve desired social values, and discuss additional policy options that are currently under debate in Israel to further promote equality and solidarity in this market by increasing accessibility to low income and other underserved populations.

Perceived need and receipt of outpatient mental health services. Factors affecting access in Israeli HMOs.

The finance and provision of care have been suggested as variables that affect the utilization of mental health services. This study compared perceived need and receipt of outpatient mental health services in a staff-model health maintenance organization (HMO) and in three HMOs with preferred provider organization (PPO) arrangements. A national random phone survey (n = 1,394) of perceived need for and receipt of mental health assistance was conducted in Israel in 1995. Health care is provided by four HMOs that differ in mental health benefits, utilization management (i.e., prior authorization and referral requirements), and availability of mental health services (i.e., pool of providers and geographic dispersal). About one-quarter of the respondents had perceived a need for help at some time in their life. Significantly fewer respondents from the HMO with a small pool of providers got help (20%) than respondents from the other HMOs, which had almost identical rates of obtaining care (40.3%, 37.3% and 40.3%). Providing generous outpatient mental health care benefits does not appear to increase the proportion of persons in need who get help. However, severely limiting the availability of services does reduce the proportion of persons getting care. Implications for regulating insurers are discussed.

A consumer-based tool for evaluating the quality of health services in the Israeli health care system following reform.

Many countries have reformed their health care systems in the past decade and, as such, the need to monitor health system performance is widely recognized. In this paper we present a method for constructing quality indicators, which were used to evaluate the reformed Israeli health care system, and demonstrate the sensitivity of these indicators to change over time and to differences in quality among health plans and among population groups. The quality indicators were developed based on consumers' reports of their experiences in the health system. The indicators were measured in periodic population telephone surveys conducted between August and October of 1995, 1997, and 1999, using a structured questionnaire in Hebrew, Arabic, or Russian, this ensured the inclusion of all major sub-groups of Israel's population. Between 1080 and 1749 people were interviewed, with a response rate of over 80% each year. Using the theory-based evaluation approach, we specified the plausible causal links among intervention (components of the National Health Insurance Law), intermediate outputs (changes in health plan organizational behavior), and consumer outcomes. This led to the identification of indicators of quality of ambulatory health services, which included measures of accessibility, availability, patient satisfaction, performance of preventive medicine, and utilization of private medical services. The consumer-based evaluation tool presented in this paper was found to be easy to apply, sensitive, and relatively inexpensive. We hope that our approach will be of use to other countries that want to evaluate system-wide change and monitor quality of services over time.

The healthcare experiences of Arab Israeli women in a reformed healthcare system.

UNLABELLED: Arab Israeli women are subject to unique social stresses deriving from their status as part of an ethno-political minority and from their position as women in a patriarchal community. Collectively, their health profiles rate poorly in comparison to Jewish Israeli women or to women in the vast majority of developed countries. OBJECTIVES: To examine the experiences of Arab Israeli women in the contemporary Israeli healthcare system, following implementation of the National Health Insurance Law (NHIL). METHODS: The study combined quantitative and qualitative research methodologies. A telephone survey utilizing a structured questionnaire was conducted during August-September 1998 among a random national sample of 849 women, with a response rate of 83%. Between the months of January and July of 2000, qualitative data was attained via participant-observation, long and short semi-structured interviews, and focus groups in one large Muslim Arab Israeli village. FINDINGS: Arab Israeli women in the national survey reported poorer self-assessed health, lower rates of care by a woman primary care physician, lower satisfaction ratings for primary care physicians and more frequently foregoing medical care than did native or immigrant Jewish Israeli women. Three major factors contributing to Arab Israeli women's healthcare experiences were elucidated by the qualitative study: (1) the threat of physical and social exposure (2) difficulties in communicating with male physicians and (3) the stifling effect of family politics and surveillance on healthcare. DISCUSSION: We discuss our findings in relation to structural changes associated with the recent reform of the Israeli health care system. We conclude by suggesting policy measures for better adapting primary care services to the needs of Arab Israeli women, and note the relevance to other systems that aim to provide service to cultural and ethno-political minorities, in which healthcare delivery is shaped by unique local circumstances.

Satisfaction with and access to community care of the chronically ill in Israel's health system.

UNLABELLED: One goal of Israel's National Health Insurance Law was to improve services for vulnerable populations. However, it was feared that this goal would not be reached for the chronically ill, due to the regulations governing health plan reimbursement and to amendments to the law that authorize additional co-payments for services. OBJECTIVE: To examine the satisfaction with and organizational and financial access to services of chronically ill patients, and compare them to those of healthy consumers. METHODS: In autumn 2001, telephone interviews were conducted with a random sample of 1790 permanent residents of Israel over age 22, 512 (28%) of whom reported having a chronic illness. RESULTS: No significant differences were found between chronically ill and healthy respondents in satisfaction with services, and few differences were found in organizational access to services. However, differences were found in financial access to services. Specifically, chronic illness had an independent positive effect on the burden of co-payments for health services and the likelihood of forfeiting care or medication due to cost. CONCLUSIONS: Increased co-payments for services may restrict access to care. To lighten the burden on vulnerable populations, it is necessary to consider discounts and lower ceilings on co-payments.

School-based obesity prevention programs: a meta-analysis of randomized controlled trials.

OBJECTIVE: Attempts have been made to reduce childhood obesity through school-based programs. Systematic reviews of studies until 2006 reported a lack of consistency about effectiveness of such programs. Presented is an updated systematic review and meta-analysis. DESIGN AND METHODS: Replication of methodology used in previous comprehensive systematic review and meta-analysis of randomized controlled trials of school-based obesity prevention programs covering studies until 2006 to review studies thru January 2012. RESULTS: Based on 32 studies (n = 52,109), programs were mildly effective in reducing BMI relative to controls not receiving intervention. Studies of children had significant intervention effects, those of teenagers did not, though the difference between the two groups was not statistically significant. Meta-regression showed a significant linear hierarchy of studies with the largest effects for comprehensive programs more than 1 year long that aimed to provide information on nutrition and physical activity, change attitudes, monitor behavior, modify environment, involve parents, increase physical activity and improve diet, particularly among children. CONCLUSIONS: Unlike earlier studies, more recent studies showed convincing evidence that school-based prevention interventions are at least mildly effective in reducing BMI in children, possibly because these newer studies tended to be longer, more comprehensive and included parental support.

Factors associated with the type of psychotropic medications purchased for common mental disorders in the largest managed care organization in Israel.

OBJECTIVE: To evaluate patient and physician characteristics associated with the type of psychotropic medications (anti-anxiety, antidepressant, or both) purchased. METHODS: The Clalit Health Care Services is the largest managed care health fund in Israel, a country that employs a universal healthcare system. We randomly sampled 30,000 primary care patients over the age of 22 as of January, 2006. RESULTS: Overall, 2,217 purchased either antidepressant or antianxiety medications at least once during the year 2006 and had no prior purchases during the last quarter of 2005. The majority (1,518; 68.4%) purchased only anti-anxiety medications and as many as 264 (12%) purchased both anti-anxiety and antidepressant medications. The remaining 435 (19.6%) patients purchased only antidepressant medications. Physician level characteristics explained only a small portion of the variance and, thus, were not included in further analysis. Several patient level characteristics, including age, somatic, and psychiatric diagnosis were associated with the purchase of different types of medications. CONCLUSIONS: Contrary to clinical guidelines, the purchase of anti-anxiety medications is more prevalent than the purchase of antidepressant medications. In a managed care setting, patient characteristics have a greater role in determining purchasing patterns than provider characteristics; potentially, because of the managed care characteristics that actively guide the care provided to patients.

Disparities in antidepressant adherence in primary care: report from Israel.

OBJECTIVES: To evaluate patient and physician characteristics associated with the purchase of antidepressant medication for at least 6 months. STUDY DESIGN AND METHODS: Clalit Health Services is the largest managed care health fund in Israel, a country that uses a universal healthcare system. We randomly sampled 30,000 primary care patients over the age of 22 years. Our analytic sample consisted of those 949 patients who did not purchase antidepressant medication during the last quarter of 2005 and purchased antidepressant medication at least once in 2006. We used multilevel analysis, with whether or not medication was purchased for at least 6 months as an indicator of adherence. Patient and physician characteristics were evaluated as potential predictors. RESULTS: Only 23% of the sample was classified as adherent. Physician characteristics explained only a small portion of the variance in adherence and, as a result, were not included in multivariate analysis. Patients who did not have a somatic diagnosis, had a depression diagnosis, and were of higher socioeconomic status were more likely to be classified as adherent. Patients who purchased tricyclic antidepressants were less likely to be classified as adherent. CONCLUSIONS: The findings suggest that in a managed care setting, there is high uniformity among physicians. Although physician characteristics explain little of the variability associated with adherence, certain patient characteristics as determined by their physicians (eg, antidepressant drug class, psychiatric diagnosis) do play a role in adherence.

Disparities in obesity temporal trends of Israeli adolescents by ethnic origin.

OBJECTIVE: To analyze the temporal trends of obesity over time among male adolescents of different ethnic origins. METHODS: Population-based national data of subjects presenting at recruitment centers for medical examinations as part of screening for military draft. Subjects were 17-year-old Jewish males (n=1 140 937) born in the years 1950-1986. Data on body mass index (BMI) were measured (without clothing and shoes) by physicians. We calculated the prevalence of obesity (BMI 29.4 or higher) for each year by ethnic origin group. A Multinomial logistic regression model was used to estimate the effects of ethnic origin and other risk factors on the likelihood of obesity. RESULTS: Over time, obesity rates have risen among all ethnic groups of adolescents. Multinomial regression analysis showed a lower likelihood of obesity among those of Asia-Africa origin as compared with other groups. However, obesity rates have increased more significantly over time among this ethnic group compared with the other groups. CONCLUSION: A significant finding of this study is the disparities in temporal trends in the likelihood of obesity over time. Among adolescents of Asia-Africa origin the likelihood of obesity increased more steeply over time compared with other groups of adolescents. Health services in Israel should thus consider Asia-African origin as a distinct risk factor and target interventions to prevent future obesity among these adolescents.
