Effects of cigarette tax on cigarette consumption and the Chinese economy.

OBJECTIVES: To analyse a policy dilemma in China on public health versus the tobacco economy through additional cigarette tax. METHODS: Using published statistics from 1980 through 1997 to estimate the impact of tobacco production and consumption on government revenue and the entire economy. These estimates relied on the results of estimated price elasticities of the demand for cigarettes in China. RESULTS: Given the estimated price elasticities (-0.54), by introducing an additional 10% increase in cigarette tax per pack (from the current 40% to 50% tax rate), the central government tax revenue would twice exceed total losses in industry revenue, tobacco farmers' income, and local tax revenue. In addition, between 1.44 and 2.16 million lives would be saved by this tax increase. CONCLUSIONS: Additional taxation on cigarettes in China would be a desirable public policy for the Chinese government to consider.

The demand for consumer health information.

Using data from an evaluation of a community-wide informational intervention, we modeled the demand for medical reference books, telephone advice nurses, and computers for health information. Data were gathered from random household surveys in Boise, ID (experimental site), Billings, MT, and Eugene, OR (control sites). Conditional difference-in-differences show that the intervention increased the use of medical reference books, advice nurses, and computers for health information by approximately 15, 6, and 4%. respectively. The results also suggest that the intervention was associated with a decreased reliance on health professionals for information.

Association of outpatient alcohol and drug treatment with health care utilization and cost: revisiting the offset hypothesis.

OBJECTIVE: This study examines the hypothesis that treatment reduces medical utilization and costs of patients with substance use problems. METHOD: Adult patients (N = 1.011; 67% men) entering the outpatient chemical dependency recovery program at Sacramento Kaiser Permanente over a 2-year period were recruited into the study. Medical utilization and costs were examined for 18 months prior and 18 months after intake. To account for overall changes in utilization and cost, an age, gender and length-of-enrollment matched nonpatient control group (N = 4,925) was selected from health-plan members living in the same service area. Multivariate analyses controlling for age and gender were conducted using generalized estimating equation methods, allowing for correlation between repeated measures and nonnormal distributions of the outcome variable. RESULTS: The treatment cohort was less likely to be hospitalized (odds ratio [OR] = 0.59; p < .01) and there was a trend for having spent fewer days (rate ratio [RR] = 0.77; p < .10) in the hospital in the posttreatment period compared to pretreatment period. These patients were also less likely to visit the emergency room (ER) (OR = 0.64; p < .01) and had fewer ER visits (RR = 0.81; p < .01) following treatment. Inpatient, ER and total medical costs declined by 35%, 39% and 26%, respectively (p < .01). Reductions in cost were greater for the treatment cohort when compared with the matched sample (p < .05). Among women, there were significant reductions (p < .05) in inpatient, ER and total costs for the study cohort when compared with the matched sample; among men, the reductions in inpatient and ER cost (but not total cost) were significantly larger (p < .05) for the study cohort when compared with the matched sample. For the treatment cohort, the change in medical cost was not significantly different by gender. Changes in cost were significantly different across the various age groups (p < .05) for the study cohort and the matched sample. Among those in the group aged 40-49 years, the decline in cost for study cohort was significantly larger (p < .05) than for the matched sample. CONCLUSIONS: For patients with substance use disorders entering treatment, there was a substantial decline in inappropriate utilization and cost (hospital and ER) in the posttreatment period. The disaggregated pattern of posttreatment decline in utilization and cost is suggestive of long-term reductions that warrant a longer follow-up.

Alcohol drinking patterns and medical care use in an HMO setting.

The objective of this study was to examine the association of medical care use (outpatient visits and hospitalization) with alcohol drinking patterns in a large health maintenance organization (HMO). Data were gathered from a random sample of 10,292 adult respondents through a telephone survey conducted between June 1994 and February 1996. Findings indicate that current nondrinkers with no past history of drinking had higher rates of outpatient visits and hospitalizations than current drinkers. Among current drinkers, medical care use declined slightly as drinking levels increased. Among nondrinkers, those with a drinking history exhibited significantly higher use of outpatient visits and hospital care than nondrinkers with no drinking history and current drinkers. Controlling for demographic and socioeconomic factors, health status, and common medical conditions in multivariate analyses suggests that nondrinkers with a drinking history use more services because they are sicker than other nondrinkers or current drinkers.

Willingness to pay for mammography: item development and testing among five ethnic groups.

The goal of this study was to develop a willingness to pay (WTP) question for mammography that is appropriate for low income, ethnically-diverse women. Through qualitative research with 50 low income women of five ethnic groups we developed both a WTP question and a willingness to travel question (WTT). After being refined through interviews with 41 women, these questions were pilot tested on a random sample of 52 low income, ethnically-diverse women in the San Francisco area. Results show that the concepts underlying WTP and WTT were culturally appropriate to the five ethnicities in this study. Analyses generally confirm the validity of the WTP and WTT questions. As expected, WTP was associated with household income, perceived risk of cancer, and knowledge that one needs a mammogram even after a clinical breast examination. Despite the small samples, WTP varied among the ethnic groups. Additionally, WTT was moderately correlated with the natural log of WTP (r = 0.58, P < 0.001). These questions are now in use in a larger clinical trial and future analyses will explore willingness to pay and willingness to travel within and across the ethnic groups.

Drinking patterns and problems of the "stably insured": a study of the membership of a health maintenance organization.

OBJECTIVE: This article describes drinking patterns and examines the prevalence of heavy drinking and alcohol problems, and their association with other behavioral and social problems within the membership of a health maintenance organization, a setting in which increasing numbers of Americans receive services. METHOD: The sample is representative of the stably insured membership of the Northern California Region of Kaiser Permanente Medical Care Program; i.e., those who have been insured continuously under that plan for 30 months or longer. A telephone survey of the adult membership (N = 10,292) was conducted between June 1994 and February 1996. RESULTS: As in other studies, health and mental health status and smoking were related to drinking levels, with symptoms higher for those in the heaviest drinking group. However, in contrast to studies of those using medical services, demographic characteristics (e.g., young age) were not associated with heavy drinking in this population. When controlling for drug use and drinking, however, women and those reporting any mental health symptom were more likely to report alcohol problems. CONCLUSIONS: Findings suggest that in private managed care populations, particular behavioral indicators may be more important than demographic characteristics in screening for problem drinkers. The identification of individuals who report a mental health symptom, who drink a large number of drinks occasionally or who report any drug use may be important in a health maintenance approach to prevention and case finding.

Cigarette consumption in rural China: survey results from 3 provinces.

OBJECTIVES: This study assessed cigarette consumption and its main determinants in rural China. METHODS: A logistic regression model was used to analyze status of smoking, daily amount of smoking, and expense of cigarettes in rural China. RESULTS: Approximately 57.1% of the males and 3.1% of the females were current smokers. The daily amount of smoking among smokers was 15.23 cigarettes, and their annual expenses were 227 yuan. CONCLUSIONS: People in rural China consume fewer cigarettes and are less likely to smoke than those in urban areas. Education and occupation are 2 major factors that determine the likelihood of smoking in rural China.

The impact of risk shifting and contracting on mental health service costs in California.

This paper identifies the impact of "program realignment," a 1991 California state policy that significantly enhanced local governments' financial risk and programmatic authority for public mental health services, on treatment costs per user, and on the mix of inpatient and outpatient service costs. The study employs a natural pre-realignment and post-realignment design using the 59 California local mental health authorities (LMHAs) as the unit of analysis over a seven-year period spanning policy implementation. Total treatment and inpatient cost per user decreases and outpatient cost per user increases after program realignment. Higher levels of contracting with private providers tend to enhance this trend, while risk for institutional services reduces user costs uniformly. Financial and programmatic decentralization can enhance cost efficiency in treatment, while promoting substitution of outpatient services for inpatient services. Local conditions such as risk and contracting determine the extent of the policy response.

Economic considerations in overactive bladder.

Many costs are associated with overactive bladder (OAB). They include direct costs, such as those associated with treatment, diagnosis, routine care, and the consequences of the disease; indirect costs of lost wages and productivity; and intangible costs associated with pain, suffering, and decreased quality of life. Quantification of all these costs is essential for establishing the total economic burden of a disease on society. Currently, the total economic burden of OAB is unknown. However, various studies have determined that the economic burden of urinary incontinence, one of the symptoms of OAB, is substantial. It is also important to establish the economic impact of various interventions for OAB. Cost-minimization, cost-outcome, cost-utility, and cost-benefit models can be used for these analyses. The most difficult aspect of evaluating the economic impact of a treatment is estimating the intangible costs.

The effects of economic reform on health insurance and the financial burden for urban workers in China.

Since 1980, Chinese enterprises have been undergoing reforms in employment practice, taxation, and workers' health/welfare benefits coverage. In particular, Chinese businesses have been facing a major challenge with respect to the financial burden of providing medical benefits to their workers. The purpose of this paper is to analyse the impact of enterprise reform on workers' health care benefits and their financial burden due to medical expenses. This study is based on a 1992 survey conducted in 22 cities, and included 406 enterprises and 5920 workers. It was found that there were wide variations of coverage for health care benefits among urban Chinese workers. It was also found that workers with partial coverage were as likely to incur out-of-pocket medical expenditures as workers without coverage. These out-of-pocket medical expenditures could reach as high as 25% of a worker's annual income. Policy recommendations are discussed at the end of the paper.

Effects of a mental health carve-out on use, costs, and payers: a four-year study.

This study examines the effects of a mental health carve-out on a sample of continuously enrolled employees (N = 1,943) over a four-year time frame (1990-1994). The article presents a health care services utilization model of the effect of the carve-out on outpatient mental health use, cost, and source of payment in the three years post implementation relative to the year prior to the carve-out model. In the first three years of the carve-out, the likelihood of employees seeking mental health care increased in significant part because of the carve-out. For the outpatient mental health services user, the carve-out was not associated with the level of mental health services received. The carve-out was significantly associated over time with a reduction in the patient's and employer's mental health costs. This effect was more pronounced in the second and third years of the carve-out. The article explores the policy implications of these and other findings.

Economic costs of urinary incontinence in 1995.

Urinary incontinence imposes a significant financial burden on individuals, their families, and healthcare organizations. For individuals 65 years of age and older these costs are substantial, increasing from $8.2 billion (1984 dollars) to $16.4 billion (1993 dollars). Both of these cost-of-illness estimates, however, relied on data and factors that have changed over time. This study updates these cost estimates. The 1995 societal cost of incontinence for individuals aged 65 years and older was $26.3 billion, or $3565 per individual with urinary incontinence. Limitations, implications, and directions for future research are also discussed.

Teenage smoking, attempts to quit, and school performance.

OBJECTIVES: This study examined the relationship between school performance, smoking, and quitting attempts among teenagers. METHODS: A logistic regression model was used to predict the probability of being a current smoker or a former smoker. Data were derived from the 1990 California Youth Tobacco Survey. RESULTS: Students' school performance was a key factor in predicting smoking and quitting attempts when other sociodemographic and family income factors were controlled. CONCLUSIONS: Developing academic or remedial classes designed to improve students' school performance may lead to a reduction in smoking rates among teenagers while simultaneously providing a human capital investment in their futures.

Mental health costs, other public costs, and family burden among mental health clients in capitated integrated service agencies.

This article explores the cost implications of the capitated integrated service agency (ISA) model for persons with severe and persistent mental illness. Two demonstration sites in California were chosen for a randomized comparison between an ISA model and usual care under the existing county service system. Each ISA demonstration program assumed fiscal and service responsibility for approximately 100 clients. Cost information was collected during a 3-year study period. The capitated ISAs reduced the previously skewed distribution of resources to clients and reduced family economic burden (in one site). However, they did not reduce law enforcement, health, and other nontreatment public costs. Although capitated funding enabled programmatic effectiveness and the shifting of services toward rehabilitation, it did not itself ensure such results.

Do cigarette producers price-discriminate by state? An empirical analysis of local cigarette pricing and taxation.

This study analyzes the interactive effects of oligopoly pricing, state taxation, and anti-smoking regulations on retail cigarette prices by state, using panel data for the 50 US states between 1960 and 1990. The results indicate that cigarette producers do price-discriminate by state, though the effect is not large relative to the final retail price. There are two further results: (1) state taxes are more than passed on - a 1-cent state tax increase results in a price increase of 1.11 cents, and (2) sellers offset state and local anti-smoking laws with lower prices, thereby blunting effects of the regulations.
