Economic costs of cigarette smoking among adolescents in Nigeria

Background

Cigarette smoking is an established cause of preventable death and often initiated during adolescence. We estimated the short- and long-term costs of cigarette smoking among currently smoking adolescents in Nigeria.

Methods

A cross-sectional survey among adolescents in Oyo state, Nigeria and a review of mortality records of patients managed for lung cancer in a tertiary facility in Ibadan, Nigeria were conducted. Short-term costs estimated were: (a) average weekly costs of purchasing cigarettes by currently smoking adolescents, and (b) costs of managing at least an episode of chronic cough occurring within 12 months of the survey. Long-term costs were limited to: (a) life-time expenditure on purchasing cigarettes, and (b) direct medical and non-medical (transportation) costs of managing lung cancer. Long-term costs were first projected to the approximate year when the adolescents (mean age:16.0 ± 1.8 years) might be diagnosed with lung cancer based on the average age at presentation with symptoms of lung cancer obtained from the records (59.8 years), and then discounted to 2020 prices. This was estimated as 44 years from the base year (2020). Costs were reported in 2020 prices in Nigerian Naira (NGN) and US dollar (USD) equivalent using the Central Bank of Nigeria, June 2020 exchange rate of USD 1: NGN 360.50.

Results

Approximately 3.8% of the adolescents were current cigarette smokers. Average weekly expenditure on cigarettes was NGN 306.82 ± 5.74 (USD 0.85 ± 0.02). About 26% had experienced at least an episode of chronic cough which cost them an average of NGN 1226.81 ± 6.18 (USD 3.40 ± 0.02) to manage. Total future costs of cigarette smoking in 2020 prices for the 43 adolescents who were current smokers in the event that they develop lung cancer were approximately NGN 175.7 million (USD 487.3 thousand), NGN 871.8 million (USD 2.4 million) and NGN 4.6 trillion (USD 12.7 million) at assumed annual inflation rates of 10%, 15%, and 20% respectively and discount rate of 4.25%.

Conclusion

The estimated economic costs of smoking were very high. Efforts to prevent smoking initiation among adolescents in our study area should be intensified. Interventions to subsidize the medical cost of health-related consequences of cigarette smoking are also required, especially as treatment costs are currently largely borne out-of-pocket.

Cost-effectiveness analysis of screening for first-degree relatives of patients with bicuspid aortic valve

Introduction

Bicuspid aortic valve (BAV) is the commonest congenital heart valve defect, found in 1% to 2% of the general population and associated with life-threatening complications. Given the high heritability index of BAV, many experts recommend echocardiography for first-degree relatives (FDRs) of an index patient. However, the cost-effectiveness of such cascade screening for BAV has not been fully evaluated.

Materials and methods

Using a decision-analytic model, we performed a cost-effectiveness analysis of echocardiographic screening of FDRs of BAV index cases. Data on BAV probabilities and BAV complications among FDRs were derived from our institution's BAV familial cohort and from the relevant literature on population-based BAV cohorts with long-term follow-up. Health gain was measured as quality-adjusted life years (QALYs). Cost inputs were based on list prices and literature data. One-way and probabilistic sensitivity analyses were performed to account for uncertainty in the model's variables.

Results and disscusion

Screening of FDRs was found to be the dominant strategy, being more effective and less costly than no screening, with savings of €208 and gains of 1.6 QALYs. Results were sensitive to the full range of reported BAV rates among FDRs across the literature, with the benefit gradually decreasing from the screening age of 55 years, with trend shifting at the age of 69.

Conclusions

This economic evaluation model revealed that echocardiographic screening of FDRs of BAV index case is not only clinically important but also highly cost effective and cost-saving. Health gains could be achieved from initiating screening program, along with costs saving. Sensitivity analysis supported the model's robustness, suggesting its generalization.

Social solidarity in healthcare: The Israeli case

While solidarity is at the basis of all social health insurance systems, little has been done to define and analyze it empirically. Equity in the delivery of medical care and progressivity of its finance are socially important, but miss the main principle of social health insurance systems - mutual help. The present study views social solidarity not as a value but as cross-subsidies among individuals, which are necessary to achieve a separation between finance and delivery of care in order to make healthcare affordable universally. A solidarity index, derived from the Kakwani Progressivity Index, is suggested and applied to the Israeli national health insurance system in 2010. The observed solidarity index for 2010 Israel is 0.242. Adjusting for possible barriers in use does not change the index. About 85% of the solidarity index originates from income solidarity. If the entire health budget was financed by the general revenue, the solidarity index would rise to 0.259. The level of solidarity in Israel is close to the one found in Canada, Finland and France. More comparative results over time and over systems will enable further insights and uses. The sustainability of solidarity requires, however, some altruism among the rich with respect to the health state of the poor.

Cost-effectiveness analysis of screening for first-degree relatives of patients with bicuspid aortic valve

AIMS

Bicuspid aortic valve (BAV) is the commonest congenital heart valve malformation, and is associated with life-threatening complications. Given the high heritability index of BAV, many experts recommend echocardiography screening for first-degree relatives (FDRs) of an index case. Here we aim to evaluate the cost-effectiveness of such cascade screening for BAV.

METHODS

Using a decision-analytic model, we performed a cost-effectiveness analysis of echocardiographic screening for FDRs of BAV index case. Data on BAV probabilities and complications among FDRs were derived from our institution's BAV familial cohort and from the literature on population-based BAV cohorts with long-term follow-up. Health gain was measured as quality-adjusted life years (QALYs). Cost inputs were based on list prices and literature data. One-way and probabilistic sensitivity analyses were performed to account for uncertainty in the model's variables.

RESULTS

Screening of FDRs was found to be the dominant strategy, being more effective and less costly than no screening, with savings of €644 and gains of 0.3 QALYs. Results were sensitive throughout the rang of the model's variables, including the full range of reported BAV rates among FDRs across the literature. A gradual decrease of the incremental effect was found with the increase in screening age.

CONCLUSIONS

This economic evaluation model found that echocardiographic screening of FDRs of BAV index case is not only clinically important but also cost-effective and cost-saving. Sensitivity analysis supported the model's robustness, suggesting its generalization.

Economic costs of terminal care for selected non-communicable diseases from a healthcare perspective: a review of mortality records from a tertiary hospital in Nigeria

INTRODUCTION

WHO revealed that morbidity and mortality from non-communicable diseases (NCDs) are on the increase and NCDs accounted for approximately 29% of all deaths in Nigeria in 2016. This study was conducted to estimate the economic cost of selected NCDs-lung cancer, liver cancer and liver cirrhosis. These diseases are known to be associated with key modifiable health risk behaviours (smoking and alcohol use), which are prevalent in Nigeria and often commence during the adolescent years.

METHODS

Data were obtained between 2016 and 2017, from mortality records of patients managed for the selected diseases in the University College Hospital, a major referral centre in Nigeria. Information on costs of treatment, clinic visits, admission and transportation was obtained. Average costs of terminal in-patient care and transportation costs (in 2020 prices) were computed per patient. Costs were converted to the US dollar equivalent using the current official rate of US$1: ₦360.50.

RESULTS

Twenty-two (out of 90 cases recorded) could be retrieved and all the patients had been diagnosed in the terminal stages of the disease. The average direct costs were ₦510 152.62 (US$1415.13) for an average of 49.2 days of terminal care for lung cancer; ₦308 950.27 (US$857.00) and ₦238 121.83 (US$660.53) for an average of 16.6 and 21.7 days of terminal care for patients managed for liver cancer and liver cirrhosis, respectively.

CONCLUSION

The economic costs of each of the diseases were very high. Findings emphasise the need for aggressive efforts to promote primary prevention, improve early diagnosis and provide affordable treatment in view of the fact that the monthly minimum wage is less than US$85.00 and treatment costs are borne out-of-pocket by the generality of the population in Nigeria.

Impact of the free healthcare initiative on wealth-related inequity in the utilization of maternal & child health services in Sierra Leone

BACKGROUND

As a result of financial barriers to the utilization of Maternal and Child Health (MCH) services, the Government of Sierra Leone launched the Free Health Care Initiative (FHCI) in 2010. This study aimed to examine the impact of the FHCI on wealth related inequity in the utilization of three MCH services.

METHODS

We analysed data from 2008 to 2013 Sierra Leone Demographic Health Surveys (SLDHS) using 2008 SLDHS as a baseline. Seven thousand three hundred seventy-four and 16,658 women of reproductive age were interviewed in the 2008 and 2013 SLDHS respectively. We employed a binomial logistic regression to evaluate wealth related inequity in the utilization of institutional delivery. Concentration curves and indices were used to measure the inequity in the utilization of antenatal care (ANC) visits and postnatal care (PNC) reviews. Test of significance was performed for the difference in odds and concentration indexes obtained for the 2008 and 2013 SLDHS.

RESULTS

There was an overall improvement in the utilization of MCH services following the FHCI with a 30% increase in institutional delivery rate, 24% increment in more than four focused ANC visits and 33% increment in complete PNC reviews. Wealth related inequity in institutional delivery has increased but to the advantage of the rich, highly educated, and urban residents. Results of the inequity statistics demonstrate that PNC reviews were more equally distributed in 2008 than ANC visits, and, in 2013, the poorest respondents ranked by wealth index utilized more PNC reviews than their richest counterparts. For ANC visits, the change in concentration index was from 0.008331[95% CI (0.008188, 0.008474)] in 2008 to - 0.002263 [95% CI (- 0.002322, - 0.002204)] in 2013. The change in concentration index for PNC reviews was from - 0.001732 [95% CI (- 0.001746, - 0.001718)] in 2008 to - 0.001771 [95% CI (- 0.001779, - 0.001763)] in 2013. All changes were significant (p value < 0.001).

CONCLUSION

The FHCI appears to be improving access to and utilization of MCH services, narrowing the inequity in ANC visits and PNC reviews, but is insufficient in addressing wealth- related inequity that exists for institutional deliveries. If Sierra Leone is to realize a significant reduction in maternal and child mortality rates, it needs to strengthen the effective implementation of FHCI considering incorporating a sector wide approach (SWAp) or a "Health in all Policy" framework to reach the less educated, rural residents and ensuring culturally sensitive quality services.

The economic burden of health disparities related to socioeconomic status in Israel

BACKGROUND

Low socioeconomic status (SES) is often associated with excess morbidity and premature mortality. Such health disparities claim a steep economic cost: Possibly-preventable poor health outcomes harm societal welfare, impair the domestic product, and increase health care expenditures. We estimate the economic costs of health inequalities associated with socioeconomic status in Israel.

METHODS

The monetary cost of health inequalities is estimated relative to a counterfactual with a more equal outcome, in which the submedian SES group achieves the average health outcome of the above-median group. We use three SES measures: the socioeceonmic ranking of localities, individuals' income, and individuals' education level. We examine costs related to the often-worse health outcomes in submedian SES groups, mainly: The welfare and product loss from excess mortality, the product loss from excess morbidity among workers and working-age adults, the costs of excess medical care provided, and the excess government expenditure on disability benefits. We use data from the Central Bureau of Statistics' (CBS) surveys and socio-health profile of localities, from the National Insurance Institute, from the Ministry of Health, and from the Israel Tax Authority. All costs are adjusted to 2014 terms.

RESULTS

The annual welfare loss due to higher mortality in socioeconomically submedian localities is estimated at about 1.1-3.1 billion USD. Excess absenteeism and joblessness occasioned by illness among low-income and poorly educated workers are associated with 1.4 billion USD in lost product every year. Low SES is associated with overuse of inpatient care and underuse of community care, with a net annual cost of about 80 million USD a year. The government bears additional cost of 450 million USD a year, mainly due to extra outlays for disability benefits. We estimate the total cost of the estimated health disparities at a sum equal to 0.7-1.6% of Israel's GDP.

CONCLUSIONS

Our estimates underline the substantial economic impact of SES-related health disparities in Israel. The descriptive evidence presented in this paper highlights possible benefits to the economy from policies that will improve health outcomes of low SES groups.

[IDENTIFYING PREDICTORS OF MENTAL HEALTH SERVICES CONSUMPTION IN ISRAEL]

INTRODUCTION

The budget for health services in Israel was recently increased to cover mental health. It was suggested to divide funds for psychiatric hospitalization between the HMOs based on their share of insured members. For ambulatory care, it was suggested to add risk adjustment based on age only to the capitation formula used for allocating health care funds. This simplistic measure encourages risk selection and discrimination of costly individuals.

AIMS

To identify predictors of mental health services consumption in Israel, in order to implement them in the capitation formula.

METHODS

Data were gathered on 27,446 individuals hospitalized in psychiatric wards in Israel in 2012-2013, and 6115 outpatients treated during this period in one mental health clinic. The association between demographic and clinical variables with services consumption was studied.

RESULTS

The average annual expenses per person on mental health were NIS 50,000 for hospitalization, NIS 1,700 for ambulatory care and NIS 7,000 for all services. Adult age and schizophrenia spectrum diagnoses predicted increased expenditure on all services. Being a male, single, Jewish and living in the economic periphery predicted increased expenditure mainly on hospitalization. Regression analysis using these variables explained up to 30% of variance.

CONCLUSIONS

It is possible to predict, at least partially, mental health consumption in Israel based on clinical and demographic variables.

DISCUSSION

Limitations of the study call or re-analysis using full databases, which are available only to the state authorities. Predictors of mental health consumption in Israel can be used for the risk adjustment of allocating funds for services.

Adherence of patients with type 2 diabetes mellitus to medications: the role of risk preferences

OBJECTIVE

To examine whether risk tolerance is associated with adherence to oral hypoglycemic agents (OHAs).

METHODS

We performed a cross-sectional study among adult patients with type 2 diabetes mellitus (n = 308) presenting for routine out-patient visits, using validated questionnaires to estimate: risk preferences (risk-seeking, risk averse, risk neutral), motivation, self-efficacy, impulsivity, perception of the disease and of the interpersonal process of care, demographic and socioeconomic characteristics; computerized patient medical records to estimate disease severity and a computerized database for retrieval of medication adherence, 1 year before the interview. Adherence was estimated using prescription-based measures of proportion of days covered (PDC). Concurrent adherence was calculated as: PDC with ≥1 OHAs; average PDC; PDC of ≥80% for all OHAs.

RESULTS

Multivariable ordered logit model revealed that compared to others, risk-seeking patients had lower PDC with ≥1 OHAs (β = -0.50, p ≤ .1). Specifically, risk-seeking patients were 11.2 percentage points less likely to have ≥80% of the follow-up period covered with ≥1 OHAs available (p ≤ .1). In addition, risk-seeking patients had lower average PDC (β = -0.85, p ≤ .05). Specifically, these patients were 19.5 percentage points less likely to have an average PDC of ≥80% (p ≤ .05). Multivariable logistic model revealed that risk-seeking was associated with lower probability of having PDC ≥80% for all OHAs in the follow-up period (OR; 90% CI: 0.59; 0.35-0.97).

CONCLUSIONS

Risk-seeking patients are less adherent to OHA medications. Identifying these patients may enable practitioners to proactively tailor strategies to improve their adherence and health outcomes.

[FORCE-FEEDING OR LIFE-SAVING? - DEALING WITH HUNGER STRIKES IN ISRAEL]

Although the management of quality of care by the health funds has contributed to its improvement, medical teams criticize the way it is performed. Many call for renewed values-driven thinking and to leave the concern for quality in the hands of the medical teams, relying on "self control and enforcement", based on values, compassion, concern for others, patient service, discipline and personal responsibility. This article aims to present an economic perspective on the measurement of quality of care. It places the development of "measuring the quality of care and its management" within the development of the organization of care, health insurance and payment arrangements for medical teams. The conclusion is that there is no "first best" method to improve the quality of care. Each method - including the quantitative-functional measurement-based method used in many systems and the value-driven, self enforced method proposed by many - has advantages and disadvantages. The choice of a method should be based on these two sides, discussed jointly by medical teams, the health funds, hospitals and the Health Ministry.

Do the equity-efficiency preferences of the Israeli Basket Committee match those of Israeli health policy makers?

Background

Prioritization of medical technologies requires a multi-dimensional view. Often, conflicting equity and efficiency criteria should be reconciled. The most dramatic manifestation of such conflict is in the prioritization of new medical technologies asking for public finance performed yearly by the Israeli Basket Committee. The aim of this paper is to compare the revealed preferences of the 2006/7 Basket Committee’s members with the declared preferences of health policy-makers in Israel.

Methods

We compared the ranking of a sample of 18 accepted and 16 rejected technologies evaluated by the 2006/7 Basket Committee with the ranking of these technologies as predicted based on the preferences of Israeli health policy-makers. These preferences were elicited by a recent Discrete Choice Experiment (DCE) which estimated the relative weights of four equity and three efficiency criteria. The candidate technologies were characterized by these seven criteria, and their ranking was determined. A third comparative ranking of these technologies was the efficiency ranking, which is based on international data on cost per QALY gained.

Results

The Committee’s ranking of all technologies show no correspondence with the policy-makers’ ranking. The correlation between the two is negative when only accepted technologies are ranked. The Committee’s ranking is positively correlated with the efficiency ranking, while the health policy-makers’ ranking is not.

Discussion

The Committee appeared to assign to efficiency considerations a higher weight than assigned by health policy-makers. The main explanation is that while policy-makers’ ranking is based on stated preferences, that of the Committee reflects revealed preferences. Real life prioritization, made under a budget constraint, enhances the importance of efficiency considerations at the expense of equity ones.

Conclusions

In order for Israeli health policy to be consistent and well coordinated across policy-makers, some discussions and exchanges are needed, to arrive at a common set of preferences with respect to equity and efficiency considerations.

Efficiency and equity considerations in the preferences of health policy-makers in Israel

Background

There is a traditional tension in public policy between the maximization of welfare from given resources (efficiency) and considerations related to the distribution of welfare among the population and to social justice (equity). The aim of this paper is to measure the relative weights of the efficiency- and equity-enhancing criteria in the preferences of health policy-makers in Israel, and to compare the Israeli results with those of other countries.

Methods

We used the criteria of efficiency and equity which were adopted in a previous international study, adapted to Israel. The equity criteria, as defined in the international study, are: severity of the disease, age (young vs. elderly), and the extent to which the poor are subsidized. Efficiency is represented by the criteria: the potential number of beneficiaries, the extent of the health benefits to the patient, and the results of economic assessments (cost per QALY gained). We contacted 147 policy-makers, 65 of whom completed the survey (a response rate of 44%). Using Discrete Choice Experiment (DCE) methodology by 1000Minds software, we estimated the relative weights of these seven criteria, and predicted the desirability of technologies characterized by profiles of the criteria.

Results

The overall weight attached to the four efficiency criteria was 46% and that of the three equity criteria was 54%. The most important criteria were “financing of the technology is required so that the poor will be able to receive it” and the level of individual benefit. “The technology is intended to be used by the elderly” criterion appeared as the least important, taking the seventh place. Policy-makers who had experience as members of the Basket Committee appear to prefer efficiency criteria more than those who had never participated in the Basket Committee deliberations. While the efficiency consideration gained preference in most countries studied, Israel is unique in its balance between the weights attached to equity and efficiency considerations by health policy-makers.

Discussion

The study explored the trade-off between efficiency and equity considerations in the preferences of health policy-makers in Israel. The way these declarative preferences have been expressed in actual policy decisions remains to be explored.

Adherence to Self-Care Behaviors among Patients with Type 2 Diabetes-The Role of Risk Preferences

OBJECTIVES

To examine whether the degree of risk aversion is associated with adherence to disease self-management among adults with type 2 diabetes.

METHODS

This was a cross-sectional study of patients with type 2 diabetes (n = 408) aged 21 to 70 years who presented for routine visits in the diabetes clinic at a university medical center in Beer-Sheva, Israel. The authors used validated questionnaires to estimate adherence, risk preferences, motivation, self-efficacy, impulsivity, perceptions about the disease and the interpersonal process of care, and demographic and socioeconomic characteristics, in addition to retrieving data from computerized patient medical records of clinical indicators of disease severity. Multivariable linear and ordered-logit models examined predictors of adherence to each self-care behavior.

RESULTS

Multivariable analyses revealed that, compared with others, risk-seeking patients reported lower general adherence (β = -0.32; P ≤ 0.05), and specifically, lower adherence to healthful eating plan (β = -0.48; P ≤ 0.1), consumption of low-fat food (β = -0.47; P ≤ 0.1), exercise (β = -0.73; P ≤ 0.05), blood glucose monitoring (β = -0.69; P ≤ 0.05), and foot care (β = -0.36; P ≤ 0.1). Risk-seeking patients did not report lower consumption of fruits and vegetables (β = -0.19; P > 0.1). Because 96% of the study population reported optimal adherence to medication, determinants of this behavior could not be analyzed.

CONCLUSIONS

Risk preference is associated with adherence to self-care behaviors. Identifying risk seekers may enable practitioners to target these patients with tailored strategies to improve adherence, thus more efficiently allocating scarce health care resources.

On the calculation of the Israeli risk adjustment rates

OBJECTIVE

The Israeli risk adjustment formula, introduced in 1995 and which serves for the allocation of the health budget to the sickness funds, is unique compared to countries with a similar national health insurance system in that it is not calculated on the basis of actual cost data of the sickness funds but on the basis of quantities retrieved from surveys. The current article aims to analyze the implications of the Israeli methodology.

METHODS

The article examines the validity of the Israeli methodology used to set the 2004 risk adjustment rates and compare these rates with the "correct" ones, which are derived from the 2004 internal relative cost scales of the sickness funds.

RESULTS

The Israeli methodology ignores services provided by the sickness funds and assumes constant unit cost across the sickness funds, an assumption which is implausible. Comparing the actual and the "correct" rates, it turns out that the actual rates over-compensate all the sickness funds for members in age 0-14, and under-compensate them for insurees aged 55+. In age 0-4, the over-compensation per capita is about NIS 1,500 while the under-compensation in age group 75+ reaches NIS 1,600.

CONCLUSIONS

The current risk adjustment formula distorts the intended competition on good quality care among the sickness funds, and turns it into a competition on profitable members. After 18 years of using incorrect rates, the Israeli risk adjustment rates should be calculated, as is common in other systems, based on individual cost data from the sickness funds.

Income-related inequalities in health and health services use in Israel

BACKGROUND

Income-related inequalities in health and in health services use pose a disturbing and challenging issue in health systems, which are based on social health insurance such as Israel.

OBJECTIVE

To explore income-related inequalities in health and in health services use in Israel in 2009-2010.

METHODS

We used the Central Bureau of Statistics file, which linked information on 7,175 households (24,595 persons) from the 2009 Health Survey and the 2010 Incomes Survey. Raw and adjusted concentration curves and indices were calculated for ten chronic conditions (adjusting for age), visits to physicians and hospitalizations (adjusting for health and location).

RESULTS

There is no income-related inequality in asthma and in cancer. The income-related inequality in the remaining eight conditions is 'pro-poor', namely, they are more prevalent among poor households. The order of the level of inequality is (from the least unequally distributed): any condition, hypertension, heart diseases, diabetes, depression, respiratory diseases, digestive diseases, and the condition with the highest income-related inequality is activities of daily living (ADL) limitations. The income-related inequality in secondary physicians' services is 'pro-rich'. The income-related inequality in primary care is 'pro- poor'. Hospitalization days are significantly more unequally - 'pro-poor' - distributed in the population.

DISCUSSION

International findings are basically similar to the ones found in this paper. Three reasons are believed to have caused these income-related inequalities: the use of preventive services, health behavior and compliance with the doctors' directions; they might constitute a useful framework for strategizing interventions. The efforts of the Ministry of Health and of the sickness funds launched in 2010 to reduce inequalities should be evaluated by repeating the present analysis with newer data.

Private and public patients in public hospitals in Australia

INTRODUCTION

The nature of the private-public mix in health insurance and in health care is a major issue in most health systems.

OBJECTIVE

To compare the hospitalization characteristics of private and public patients hospitalized in public hospitals.

METHODS

We focused on planned, overnight and same-day admissions, discharged during 2004-2005 from the public New South Wales hospitals, and run fixed-effects regressions in order to identify the effect of accommodation status (private/public) on the hospitalization characteristics.

RESULTS

Private patients have one third less waiting days than public patients, and they are assigned higher urgency of admission. Length of stay and length of visit are both unrelated to the accommodation status, however, private patients tend to have more hours in ICU and more procedures performed during the hospitalization. In-hospital mortality and the number of transfers (wards) are not affected by the accommodation status.

CONCLUSIONS

Private patients are treated differently than public patients in public hospitals, reinforcing the private health insurance-related inequity in inpatient care identified by others. Two health policy issues emerge from the findings: the role of private health insurance in the Australian socialized medicine system, and in particular, in the public hospitals; and the way public hospitals are reimbursed for private patients.

Cost-effectiveness of baseline low-dose computed tomography screening for lung cancer: the Israeli experience

OBJECTIVE

Reduced mortality with low-dose computed tomography (LDCT) lung cancer screening was demonstrated in a large randomized controlled study of high-risk individuals. Cost-effectiveness must be assessed before routine LDCT screening is considered. We aimed to evaluate the cost-effectiveness of LDCT lung cancer screening in Israel.

METHODS

A decision analytic framework was used to evaluate the decision to screen or not screen from the health system perspective. The screening arm included 842 moderate-to-heavy smokers aged 45 years or older, screened at Hadassah-Hebrew University Medical Center from 1998 to 2004. In the usual-care arm, stage distribution and stage-specific life expectancy were obtained from the Israel National Cancer Registry data for 1994 to 2006. Lifetime stage-specific costs were estimated from medical records of patients diagnosed and treated at Hadassah Medical Center in the period 2003 to 2004. The analysis considered possible biases-lead time, overdiagnosis, and self-selection. Cost per quality-adjusted-life-year (QALY) gained by screening was estimated.

RESULTS

Base-case incremental cost per QALY gained was $1464 (2011 prices). Extensive sensitivity analysis affirmed the low cost per QALY gained. The cost per QALY gained is lower than $10,000 with probability 0.937 and is lower than $20,000 with probability 0.978.

CONCLUSIONS

Our analysis suggests that baseline LDCT lung cancer screening in Israel presents a good value for the money and should be considered for inclusion in the National List of Health Services financed publicly.

Adjusting health expenditure for military spending and interest payment: Israel and the OECD countries

Background

Compared to OECD countries, Israel has a remarkably low percentage of GDP and of government expenditure spent on health, which are not reflected in worse national outcomes. Israel is also characterized by a relatively high share of GDP spent on security expenses and payment of public debt.

Objectives

To determine to what extent differences between Israel and the OECD countries in security expenses and payment of the public debt might account for the gaps in the percentage of GDP and of government expenditures spent on health.

Methods

We compare the percentages of GDP and of government expenditures spent on health in the OECD countries with the respective percentages when using primary civilian GDP and government expenditures (i.e., when security expenses and interest payment are deducted). We compared Israel with the OECD average and examined the ranking of the OECD countries under the two measures over time.

Results

While as a percentage of GDP, the national expenditure on health in Israel was well below the average of the OECD countries, as a percentage of primary civilian GDP it was above the average until 2003 and below the average thereafter. When the OECD countries were ranked according to decreasing percent of GDP and of government expenditure spent on health, adjusting for security and debt payment expenditures changed the Israeli rank from 23rd to 17th and from 27th to 25th, respectively.

Conclusions

Adjusting for security expenditures and interest payment, Israel's low spending on health as a percentage of GDP and as a percentage of government's spending increases and is closer to the OECD average. Further analysis should explore the effect of additional population and macroeconomic differences on the remaining gaps.

Preconditions for efficiency and affordability in competitive healthcare markets: are they fulfilled in Belgium, Germany, Israel, the Netherlands and Switzerland?

CONTEXT

From the mid-1990s several countries have introduced elements of regulated competition in healthcare. The aim of this paper is to identify the most important preconditions for achieving efficiency and affordability under regulated competition in healthcare, and to indicate to what extent these preconditions are fulfilled in Belgium, Germany, Israel, the Netherlands and Switzerland. These experiences can be worthwhile for other countries (considering) implementing regulated competition (e.g. Australia, Czech Republic, Ireland, Russia, Slovakia, US).

METHODS

We identify and discuss ten preconditions derived from the theoretical model of regulated competition and assess the extent to which each of these preconditions is fulfilled in Belgium, Germany, Israel, the Netherlands and Switzerland.

FINDINGS

After more than a decade of healthcare reforms in none of these countries all preconditions are completely fulfilled. The following preconditions are least fulfilled: consumer information and transparency, contestable markets, freedom to contract and integrate, and competition regulation. The extent to which the preconditions are fulfilled differs substantially across the five countries. Despite substantial progress in the last years in improving the risk equalization systems, insurers are still confronted with substantial incentives for risk selection, in particular in Israel and Switzerland. Imperfect risk adjustment implies that governments are faced with a complex tradeoff between efficiency, affordability and selection.

CONCLUSIONS

Implementing regulated competition in healthcare is complex, given the preconditions that have to be fulfilled. Moreover, since not all preconditions can be fulfilled simultaneously, tradeoffs have to be made with implications for the levels of efficiency and affordability that can be achieved. Therefore the optimal set of preconditions is not only an empirical question but ultimately also a matter of societal preferences.

Community healthcare in Israel: quality indicators 2007-2009

BACKGROUND

The National Program for Quality Indicators in Community Healthcare in Israel (QICH) was developed to provide policy makers and consumers with information on the quality of community healthcare in Israel. In what follows we present the most recent results of the QICH indicator set for 2009 and an examination of changes that have occurred since 2007.

METHODS

Data for 28 quality indicators were collected from all four health plans in Israel for the years 2007-2009. The QICH indicator set examined six areas of healthcare: asthma, cancer screening, cardiovascular health, child health, diabetes and immunizations for older adults.

RESULTS

Dramatic increases in the documentation of anthropometric measures were observed over the measurement period. Documentation of BMI for adolescents and adults increased by 30 percentage points, reaching rates of 61% and 70%, respectively, in 2009. Modest increases (3%-7%) over time were observed for other primary prevention quality measures including immunizations for older adults, cancer screening, anemia screening for young children, and documentation of cardiovascular risks. Overall, rates of recommended care for chronic diseases (asthma, cardiovascular disease and diabetes) increased over time. Changes in rates of quality care for diabetes were varied over the measurement period.

CONCLUSIONS

The overall quality of community healthcare in Israel has improved over the past three years. Future research should focus on the adherence to quality indicators in population subgroups and compare the QICH data with those in other countries. In addition, one of the next steps in assessing and further improving healthcare quality in Israel is to relate these process and performance indicators to health outcomes.

Switching sickness funds in Israel: adverse selection or risk selection? Some insights from the analysis of the relative costs of switchers

This paper uses medical care costs of joiners in their first year and of leavers in their last year prior the move, relative to the age-sex groups' means, to examine the mechanisms behind the switching decisions. Since under the Israeli National Health Insurance Scheme no premiums are paid by the enrollees directly to the sickness funds, the paper focuses on the distinction between demand-side-adverse-selection type and supply-side-risk-selection type of reasons for switching. The latter is particularly important because of the incomplete Israeli age-based risk-adjustment scheme. The findings indicate that leavers are less costly than average, and thus their leaving cannot be attributed to dumping or restricted care. Joiners are more costly than average in younger ages and less costly than average in advanced age. A particular group of young joiners seems to consist of women looking for pre- and/or post-natal care. The current generous capitation rate for children provides future compensation for this first year loss.

[What determines the market shares of the health funds in Israeli localities?]

BACKGROUND

Four health funds operate nationally in Israel, but their local market shares vary dramatically across localities.

OBJECTIVES

To identify the main localities' characteristics which affect the size of the market shares of the various health funds.

METHODS

A total of 60 Localities with more than 20,000 inhabitants were chosen. The following Localities' characteristics were retrieved for the year 2004: the market shares of the four health funds, average income, standardized mortality ratio (SMR), periphery index, the age structure, the distance from the nearest general hospital, the share of Arab population, and size. Four market share equations were estimated using SURE (seemingly unrelated regressions estimation), allowing for inter-equation correlations.

RESULTS

The results show that the market shares of the different health funds are affected by different factors. Clalit Health Services' (CHS) share increases with the distance from Tel Aviv and SMR, and decreases with the level of mean income and the distance from the nearest CHS hospital. Leumit's market share increases only with the distance from a CHS's hospital. The market share of Maccabi Healthcare Services is higher in central localities, Jewish localities, small cities and further away from a non-CHS hospital. Meuhedet's market share is higher in big cities, rich and healthy localities, and in Localities which are further away from CHS's hospitals.

CONCLUSIONS

These findings indicate that the presence of the health funds in different Localities varies according to the Localities' characteristics. There appears to be a market segmentation and "specialization" of certain health funds in specific populations, and of the other health funds in the rest of the population.

Costs of appropriate and inappropriate use of antibiotics in the emergency department

BACKGROUND

Appropriate antibiotic use is of both clinical and economic significance to any health system and should be given adequate attention. Prior to this study, no in-depth information was available on antibiotic use patterns in the emergency department of Hadassah Medical Center.

OBJECTIVES

To describe the use and misuse of antibiotics and their associated costs in the emergency department of Hadassah Medical Center.

METHODS

We analyzed the charts of 657 discharged patients and 45 admitted patients who received antibiotics in Hadassah's emergency department during a 6 week period (29 April - 11 June 2007). A prescription was considered appropriate or inappropriate if the choice of antibiotic, dose and duration by the prescribing physician after diagnosis was considered suitable or wrong by the infectious diseases consultant evaluating the prescriptions according to Kunin's criteria.

RESULTS

The overall prescribing rate of antibiotics was 14.5% (702/4830) of which 42% were broad-spectrum antibiotics. The evaluated antibiotic prescriptions numbered 1105 (96 prescriptions containing 2 antibiotics, 2 prescriptions containing 3 antibiotics), and 54% of them were considered appropriate. The total inappropriate cost was 3583 NIS (1109 USD PPP) out of the total antibiotic costs of 27,300 NIS (8452 USD PPP). The annual total antibiotic cost was 237,510 NIS (73,532 USD PPP) and the annual total inappropriate cost was 31,172 NIS (9648 USD PPP). The mean costs of inappropriate prescriptions were highest for respiratory (112 NIS, 35 USD PPP) and urinary tract infection (93 NIS, 29 USD PPP). There were more cases when the optimal cost was lower than the actual cost (N = 171) than when optimal cost was higher than the actual cost (N = 9). In the first case, the total inappropriate costs were 3805 NIS (1178 USD PPP), and in the second case, -222 NIS (68.7 USD PPP).

CONCLUSIONS

The use of antibiotics in emergency departments should be monitored, especially in severely ill patients who require broad-spectrum antibiotics and for antibiotics otherwise restricted in the hospital wards. Our findings indicate that 12% of the total antibiotic costs could have been avoided if all prescriptions were optimal.

Inequality in treatment use among elderly patients with acute myocardial infarction: USA, Belgium and Quebec

BACKGROUND

Previous research has provided evidence that socioeconomic status has an impact on invasive treatments use after acute myocardial infarction. In this paper, we compare the socioeconomic inequality in the use of high-technology diagnosis and treatment after acute myocardial infarction between the US, Quebec and Belgium paying special attention to financial incentives and regulations as explanatory factors.

METHODS

We examined hospital-discharge abstracts for all patients older than 65 who were admitted to hospitals during the 1993-1998 period in the US, Quebec and Belgium with a primary diagnosis of acute myocardial infarction. Patients' income data were imputed from the median incomes of their residential area. For each country, we compared the risk-adjusted probability of undergoing each procedure between socioeconomic categories measured by the patient's area median income.

RESULTS

Our findings indicate that income-related inequality exists in the use of high-technology treatment and diagnosis techniques that is not justified by differences in patients' health characteristics. Those inequalities are largely explained, in the US and Quebec, by inequalities in distances to hospitals with on-site cardiac facilities. However, in both Belgium and the US, inequalities persist among patients admitted to hospitals with on-site cardiac facilities, rejecting the hospital location effect as the single explanation for inequalities. Meanwhile, inequality levels diverge across countries (higher in the US and in Belgium, extremely low in Quebec).

CONCLUSION

The findings support the hypothesis that income-related inequality in treatment for AMI exists and is likely to be affected by a country's system of health care.

Economic evaluation of the decisions of the Israeli Public Committee for updating the National List of Health Services in 2006/2007

OBJECTIVE

The Public Committee (PC), which decides on the inclusion and ranking of new technologies in the Israeli List of Health Services facing a given budget, does not explicitly consider the results of economic evaluations of the technologies discussed. The present article includes an ex post economic examination of the PC's 2006/2007 decisions.

METHODS

The cost per quality-adjusted life-year (QALY) (CPQ) values of the technologies approved and rejected were retrieved from national health technologies assessments and the professional literature.

RESULTS

CPQ values were found for 40 technologies out of the 52 that were approved by the PC, and for 26 out of 42 randomly sampled among those rejected. The technologies approved for inclusion produce QALYs in a cheaper way, in general, than those rejected. A CPQ of about 50,000 new Israeli shekels (NIS) (15,500 USDPPP [purchasing power parity adjusted U.S. dollars]) is identified as the best discriminating value between approved and rejected technologies. The agreement between the PC's ranking of the approved technologies and the ranking by CPQ is low, and the only significant determinant of the Committee's ranking is the number of patients expected to benefit from the technology.

CONCLUSIONS

Although not considering CPQ data explicitly, the PC tends, in fact, to approve technologies with relatively low CPQ. In ranking the approved technologies, however, the PC tries to maximize the number of persons expected to benefit from the additional budget even at the expense of possibly giving up cheaper QALYs. The size of the budget should be determined in accordance with an Israeli value of QALY and Israeli values of the CPQ of the technologies submitted for inclusion.

[Economic examination of the 2006/7 update of the Israeli national list of health services]

BACKGROUND

The Public Committee bases its choices on clinical, ethical and social considerations, and not, in general, on the (minimal) cost per Quality Adjusted Life Year (QALY) of the technologies.

OBJECTIVES

To examine the Public Committee's 2006/7 decisions from an economic viewpoint.

METHODS

The examination analyzes the findings from reviews of: 1) Recent studies which estimated the Value of Statistical Life (VSL), and hence the value of QALY, in Israel and abroad, and 2) Reports of the costs per QALY of the technologies adopted.

RESULTS AND CONCLUSIONS

The paper recommends that the Israeli willingness to pay (WTP) for human life is set at NIS 10 million, for life year at NIS 200,000 and for QALY at NIS 250,000. While the Committee's ranking of the 40 technologies, on which data was found, does not match the ranking by cost per QALY, the cost per QALY of all but three (Avastin, Myozyme and Zomera) was below NIS 250,000, and of most of the technologies was below NIS 150,000. Apart from these cases--which can be argued for on social-ethical-political specific grounds--the costs per QALY are below the WTP. In order to achieve an efficient and equitable allocation of national resources to areas which improve safety and health, the social WTP for life and for QALY must be seriously and publicly discussed.

Does greater exposure to own-health data make a difference on the visual analog scale?

The Visual Analog Scale (VAS) has become popular in eliciting valuation of health-related quality of life. The aim of the study was to explore the effect of greater exposure to own-health data on the VAS evaluation. A survey of 2,500 individuals included three measurements of the VAS, which differed in time and in the accumulated recall data to which the respondent had been exposed. Agreement among the three measurements was tested in several ways. The results generally showed that the VAS is a stable measure. The intraclass correlation coefficient (ICC) was 0.881. The paired t-tests indicated that the differences between the measurements were insignificant. More than half of the sample reported exactly the same VAS value in the three measurements. The use of the VAS measure, without any other preparation, seems to invoke the own-health data needed to report an accurate evaluation of health-related quality of life at any point in time.

Deriving a risk-adjustment formula for hospital financing: Integrating the impact of socio-economic status on length of stay

The imperfect risk adjustment of prospective payment for hospitals may have dramatic consequences on equity. If the hospital is able to distinguish subgroups of patients with different expected costs within a group for which the risk-adjusted payment per admission is the same, it is likely to select the most profitable cases and deny care to the others. Meanwhile, hospitals refusing to practice patients' selection may experience solvency problems. In the long term, either those hospitals fail and access to care is at risk, or they decrease the quality of treatments and access to quality is at risk. In Belgium, since 1995, a prospective payment per case has replaced the traditional per diem payments for non-medical expenditures. A fixed number of days are paid to each admission, based on the patient's characteristics, namely diagnosis, age and geriatric profile. In this paper, we examine the imperfect risk adjustment related to the non-inclusion of socio-economic factors in the hospital financing formula. Using data from 61 Belgian hospitals from 1995, we observe that socio-economic status, which is currently not accounted for as risk adjuster, has a significant impact on length of stay (LOS). We estimate that patients in the upper-income categories, patients with a self-employed status and patients with an employee status are beneficial for hospitals' financial results, due to their shorter stays. On the contrary, the non-active, the low-income patients and patients benefiting from an insurance preferential regime represent, on average, a financial loss for hospitals. Finally, we find that financial results under the current financing scheme are biased due to the non-inclusion of SES risk-adjustors. Hospitals with the most beneficial social case-mix are shown to experience a shift from a positive to a negative financial outcome when SES risk adjustors are included, while the reverse is observed for hospitals with the worst social case-mix.

Health behavior and religiosity among Israeli Jews

Research findings have shown the protective effect of religiosity --among both Christians and Israeli Jews--in terms of morbidity and mortality. To explore the relationship between religiosity and health behavior as a possible explanation for these findings we conducted 3056 telephone interviews, representing the Israeli adult urban Jewish population. Health status, health behavior, frequency of medical checkups, and eating habits were measured. Logistic regressions were used to estimate the religiosity gradient on health behavior, controlling for other personal characteristics. We found a lower prevalence of stress and smoking among religious persons; we also found that religious women exercise less than secular women and that religious people--both men and women--are more obese than their secular counterparts. While no religiosity gradient was found with relation to the frequency of blood pressure, cholesterol and dental checkups, religious women are less likely to undergo breast examinations and mammography. Finally, religious people generally follow a healthier dietary regime, consuming less meat, dairy products and coffee, and much more fish. The lower smoking rates, lower levels of stress, and the healthier dietary regime are consistent with the previously shown longer life expectancy of religious people; however, obesity might become a risk factor in this community.

Carrier screening for Gaucher disease: lessons for low-penetrance, treatable diseases

CONTEXT

The aim of carrier screening is to prevent severe, untreatable genetic disease by identifying couples at risk before the birth of an affected child, and providing such couples with options for reproductive outcomes for affected pregnancies. Gaucher disease (GD) is an autosomal recessive storage disorder, relatively frequent in Ashkenazi Jews. Carrier screening for GD is controversial because common type 1 GD is often asymptomatic and effective treatment exists. However, screening is offered to Ashkenazi Jews worldwide and has been offered in Israel since 1995.

OBJECTIVE

To examine the scope and outcomes of nationwide GD screening.

DESIGN, SETTING, AND PARTICIPANTS

All Israeli genetic centers provided data on the number of individuals screened for GD, the number of carriers identified, the number of carrier couples identified, and the mutations identified in these couples between January 1, 1995, and March 31, 2003. Carrier couples were interviewed via telephone between January 21, 2003, and August 31, 2004, using a structured questionnaire for relevant outcome measures.

MAIN OUTCOME MEASURES

Screening scope (number of testing centers, tested individuals, and carrier couples), screening process (type of pretest and posttest consultations), and screening outcomes (utilization of prenatal diagnosis and pregnancy terminations).

RESULTS

Between January 1, 1995, and March 31, 2003, 10 of 12 Israeli genetic centers (83.3%) offered carrier screening. Carrier frequency was 5.7%, and 83 carrier couples were identified among an estimated 28,893 individuals screened. There were 82 couples at risk for offspring with type 1 GD. Seventy of 82 couples (85%) were at risk for asymptomatic or mildly affected offspring and 12 of 82 couples (15%) were at risk for moderately affected offspring. At postscreening, 65 interviewed couples had 90 pregnancies, and prenatal diagnosis was performed in 68 pregnancies (76%), detecting 16 fetuses with GD (24%). Pregnancies were terminated in 2 of 13 fetuses (15%) predicted to be asymptomatic or mildly affected and 2 of 3 fetuses (67%) with predicted moderate disease. There were significantly fewer pregnancy terminations in couples who in addition to genetic counseling had medical counseling with a GD expert (1 of 13 [8%] vs 3 of 3 with no medical counseling [100%], P = .007).

CONCLUSIONS

In this study of GD screening among Ashkenazi Jewish couples in Israel, most couples did not terminate affected pregnancies, although screening was associated with a few pregnancy terminations. The main possible benefit was providing couples with knowledge and control. The divergence of these outcomes from stated goals of screening programs is likely to confront carrier screening programs for low-penetrance diseases.

It might be premature to reject the assumption of a power curve relationship between VAS and SG data: three comments on Stevens, McCabe and Brazier's 'Mapping between VAS and SG data; results from the UK HUI Index 2 valuation survey'

In a recent paper in Health Economics, Stevens, McCabe and Brazier (Health Econ. 2006; 15: 527-533.) found that the cubic relationship between Visual Analog Scale (VAS) values and standard gamble (SG) utilities was superior to other functional forms in terms of explanatory power and predictive ability. Consequently, they question the reliance on the assumption of a power curve relationship, which was established, theoretically and empirically, in earlier works. This note argues that: (1) SMB's conclusions are incorrect. The estimated cubic function overfits the four data points, and is questionable with respect to the implied attitude toward relative risk. (2) The evaluation of the functional forms in terms of the individual predictions' mean absolute error is misleading and (3) correcting for heteroscedasticity improves the precision of the estimates and of the predictions.

3-D non-coplanar conformal radiotherapy compared to traditional beam arrangements for the adjuvant treatment of gastric cancer

15145

Background: The Current standard of adjuvant treatment for gastric cancer following curative resection is concurrent administration of radiation and 5FU-based chemotherapy (INT0116). Radiation fields are often arranged as AP-PA opposed parallel fields with general recommendations for sparing at least two thirds of one kidney. In the current trial we investigated whether a better radiation distribution is achievable with 3-D conformal approaches as opposed to classical AP-PA fields. Methods: Nineteen patients with adenocarcinoma of stomach were treated by adjuvant chemoradiotherapy using a non-coplanar four field arrangement. In each case parallel planning by AP-PA arrangement and four fields “box was carried out and the generated plans were subsequently compared with dose volume histograms (DVH). Adequate coverage of the CTV was the basis for a comparison between other planning parameters. Separate analysis was performed not for right and left kidney but rather for kidneys exposed to higher and lower doses in each patient (since kidney dose is mostly a function of tumor location inside the stomach and respective nodal drainage). Mean dose of irradiation (MD) and percentage of kidney volume receiving radiation over 20 Gy (V20) were registered. Statistical analysis was performed by 2-tailed T-test. Results: The clinical target volume was adequately covered in all three plannings. In the “higher dose” kidneys group all the differences were statistically significant with the benefit of 3-D plan. In the “lower dose” kidneys group MD differences didn’t reach the level of statistical significance, while V20 data showed statistically significant benefit for 3-D plan. These data indicate that even when the mean doses of radiation are similar, 3-D planning can result in better distribution within the organ - thereby reducing the percentage of organ receiving dose above 20 Gy. DVH of spine was significantly better in 3-D planning. The exposure of liver was minimal in AP-PA technique. Conclusion: Noncoplanar 3-D based conformal planning for postoperative radiation therapy of gastric cancer provides the best results regarding kidney and spinal cord exposure with adequate CTV coverage.

It's time to choose the study design!: net benefit analysis of alternative study designs to acquire information for evaluation of health technologies

Uncertainty in the decision-making process for reimbursement of health technologies could be reduced if additional information were available. Although methods to evaluate the monetary value of the uncertainty have been previously described, an economic evaluation of alternative methods to acquire additional information has not yet been thoroughly explored. Should resources be allocated to a retrospective study design or to a randomised controlled trial (RCT) when additional information is deemed justified? We propose an approach for cost-effectiveness analysis of designs of future studies that are required to evaluate health technologies for reimbursement. Biases inherent in study designs are the main factor that differentiates the ability of the studies to predict the technology's benefit. By quantifying this inherent-bias effect, the incremental effectiveness of future studies can be evaluated. Economic consequences of decisions regarding prioritization of the technologies, along with the expected costs incurred by the study's execution, account for the cost component of the equation. Deducting the result retrieved for the retrospective design from that of the RCT design gives the net information benefit.

Are users of complementary and alternative medicine sicker than non-users?

Higher utilization of complementary and alternative medicine (CAM), both in cross-sections and over time, is commonly related to better socioeconomic status and to increased dissatisfaction with conventional medicine and its values. Little is known about health differences between users and non-users of CAM. The objective of the paper is to explore the difference in health measured by the SF-36 instrument between users and non-users of CAM, and to estimate the relative importance of the SF-36 health domains scales to the likelihood of consulting CAM providers. Interviews were used to collect information from a sample of 2000 persons in 1993 and 2500 persons in 2000, representing the Israeli Jewish urban population aged 45–75 in those years. Bivariate and logistic regression analyses were used to explore the above associations. The results show that while users of CAM enjoy higher socioeconomic status and younger age, they tend to report worse health than non-users on the eight SF-36 health domains scales in both years. However, controlling for personal characteristics, lower scores on the bodily pain, role-emotional and vitality scales are related to greater likelihood of CAM use in 2000. In 1993, no scale had a significant adjusted association with the use of CAM. The conclusions are that CAM users tend to report worse health. With CAM becoming a mainstream, though somewhat luxurious, medical practice, pain and affective-emotional distress are the main drivers of CAM use.

Health and religiosity among Israeli Jews

BACKGROUND

The objective of this paper is to explore the connection between self-reported health and religiosity among Israeli Jews, using several self-reported health measures.

METHODS

Data were collected by two health surveys covering 1999 individuals in 1993 and 2505 individuals in 2000, representing the population of Jewish Israelis aged 45-75 years residing in urban communities in those years. Self-reported health was measured by (i) reported chronic conditions, (ii) the SF-36 instrument, and (iii) a visual analogue scale of health-related quality of life. Religiosity was measured by a self-reported five-category scale.

RESULTS

Controlling for a large array of socio-demographic characteristics, while no religiosity gradient was found in reported chronic morbidity, religious persons generally report worse health than secular persons on the other measures. The gap is larger in the SF-36's role-performance scales, and among women and Israelis from Asian-African origin.

DISCUSSION

The mixed results are consistent with the ambiguity of the religiosity effect on health reported in recent surveys. However, trying to reconcile between longer life expectancy of religious persons found in earlier Israeli and other research and poorer reported health found above, the paper emphasizes the possible differences in the perception of 'normal' life and roles, and argues that the SF-36 health measures might suffer from a religiosity-related reporting heterogeneity, distorting their association with mortality in the population.

Development of a capitation scale for IDF career soldiers in Israel

The Israeli National Health Insurance Law allocates a national healthcare budget to the sickness funds, which provide medical care to civilian population. Medical care for members of the IDF is financed through the budget of the Ministry of Defense and is not included in the national healthcare budget. Benefits provided to soldiers serving in the permanent forces are far more extensive than those provided to civilians. Because of no co-payments, poor management, and the cost-based budget, military healthcare costs in Israel are expected to exceed civilian healthcare costs, adjusting for age and sex. The present paper derives age- and sex-based capitation rates for military personnel, and compares military and civilian age-based expenditure and capitation rates. The study population comprised career soldiers and civilians aged 21-54 years. Expenses of career soldiers were calculated to provide information on the financial costs of medical services for each age group in 2003. Overall expenses for women were higher than for men in all age groups. As anticipated, the older the group, the higher the total expenditure for both men and women. In-patient care represented a higher percentage of the total costs for men (28.3%) than for women (22.1%). Emergency room care was higher for women in the 22-24 age group but comparable to that of men in higher age groups. Specialist visits represented a significantly higher percentage of the total costs for women than for men in the 22-24 and 25-34 age groups (by 6% and 15%, respectively). The difference decreased to 13% in the 35-44 age groups and, in the 45-54 age group, the difference for men was 14% higher than for women. Military costs were similar to civilian costs in the 22-24 age groups, higher in the following two groups, and lower in the 45-54 age group. Like in other organizations, military healthcare services might benefit from outsourcing. The inequality in medical services to soldiers and civilians, the over-use of the military healthcare system, and the decrease of standards and budgetary resources will compel the establishment of more creative means of providing these services through contracts and agreements, perhaps through the civilian sickness funds.

Satisfaction with Family Physicians and Specialists and the use of Complementary and Alternative Medicine in Israel

Higher utilization of complementary and alternative medicine (CAM) is commonly explained by dissatisfaction or disappointment with conventional medical treatment. To explore, at two points in time in Israel, the associations between six domains of satisfaction (attitude, length of visits, availability, information sharing, perceived quality of care and overall) with conventional family physicians' and specialists' services and the likelihood of consulting CAM providers. This is a secondary analysis of interviews, which were conducted with 2000 persons in 1993 and 2500 persons in 2000, representing the Israeli Jewish urban population aged 45–75 in those years. Bivariate and multivariate analyses were used in the investigation. In 1993, users of CAM were less satisfied than non-users with both family physicians' and specialists' care. Lower satisfaction with the attitude of, the amount of information sharing by and in general with family physicians, and with the length of visits and perceived quality of care of specialists were significantly associated with CAM use. In 2000, lower satisfaction with specialists' attitude, length of visits, availability and in general was significantly related to the use of CAM. Lower satisfaction with family physicians and specialists is significantly associated with consulting CAM providers. However, with CAM becoming a mainstream medical care specialty in its own, lower satisfaction with conventional medicine specialists becomes the most important factor.

Complementary and alternative medicine: Beyond users and nonusers

BACKGROUND

Studies of complementary and alternative medicine (CAM) commonly distinguish between "users" and "nonusers".

OBJECTIVES

To examine the group of "users" of CAM practitioners' services, and to characterize its heterogeneity in relation to the conventional medicine system.

DESIGN

The heterogeneity of CAM users was examined with respect to three variables: user-type-CAM only or both CAM and conventional therapies, provider-type-CAM provider is a medical doctor or not, and referral-type-by a physician or self-referral.

METHODS

The data are drawn from two health surveys conducted among 4500 persons representing the Israeli Jewish urban population aged 45-75 in 1993 and in 2000.

RESULTS

Multivariate analyses confirm the heterogeneity of CAM users, and indicate that the variation within "users" is often larger than the variation between "users" and "nonusers".

CONCLUSIONS

For a better understanding of consumers' behavior with respect to CAM use, one must go beyond the classical classification of "users" versus "nonusers". The present analysis offers three additional dimensions-user-type, provider-type, and referral-type.

The Visual Analog rating Scale of health-related quality of life: an examination of end-digit preferences

Background

The Visual Analog Scale (VAS) has been extensively used in the valuation of health-related quality of life (HRQL). The objective of this paper is to examine the measurement error (rounding) explanation for the higher prevalence of VAS scores ending with a zero, and to provide an alternative interpretation.

Methods

The analysis is based on more than 4,500 reported VAS valuations of own HRQL, included in two Israeli health surveys (1993 and 2000). Bivariate and logistic regression analyses are used.

Results

The results show that reporting VAS scores ending with a 0 (...-20, ..0,10,20.....) decreases and scores ending with a 5 (...-15,-5,5,15,25,...) and with any other integer (...-12, -11,...1,2,...,92,..99) increases as VAS scores depart from 50, particularly when increasing up to 100. This pattern remains after controlling for personal characteristics determining the level of VAS.

Discussion

Rounding true HRQL to the nearest 10's or 5's cannot explain the specific pattern found. It is suggested that this pattern corresponds to a S-shaped value function, where individuals tend to evaluate their HRQL as "gains" or "losses" relative to a reference point evaluated at 50. This particular reference score originates from being a traditional "passing threshold" and the scale's midpoint. Several implications of this interpretation to the measurement of HRQL are discussed.

Assessing the in-hospital survival benefits of intensive care

Objectives:For an efficient and fair allocation of medical resources, one must know which patients benefit more from medical care. The objective of this study is to assess the differential survival benefits of a general intensive care unit (ICU) by acute diagnoses and by Acute Physiological and Chronic Health Evaluation (APACHE II) scores.

Methods:The sample included all patients triaged for admission to the Hadassah-Hebrew University Medical Center ICU during a 7-month period (n = 381). The potential effect of ICU on in-hospital survival was estimated by a bivariate (admission–survival) probit model, using crowding in the unit as the identifying variable, controlling for observable patients characteristics: age, sex, acute diagnoses, and APACHE II score. Using the estimates, the differential predicted survival benefits of ICU were calculated for selected general acute diagnoses and for different APACHE II scores.

Results:Adjusting for age, sex, and general acute diagnoses, the average potential survival benefit of ICU is 17 percentage points (pts). The benefit of ICU for patients with central nervous system problems, with sepsis, or with respiratory failure are higher than average (23 pts). Adjusting for APACHE II scores as well increases the estimated average potential benefit to 21 pts. Over the range of APACHE II scores, the highest benefit (38 pts of potential benefit) is attained for patients with scores around 22.

Conclusions:Survival benefits differ across diagnoses and APACHE II scores. Facing limited resources, admission policies should distinguish between survival probabilities (and survival maximization) and survival benefits (and maximization of ICU benefits). Actual referral and admission policies to the present ICU do not maximize the potential survival benefits of ICU resources.
