The consequences of universalizing health services: children's use of health services in Catalonia

The purpose of this study was to assess the role of needs and social factors in the use of health services among children under age 15 in Catalonia, Spain, where health care reform was explicitly designed to facilitate universal access to primary care according to health needs. Data from the Catalan Health Interview Survey of 1994, a multistage probability sample (2,433 children under 15 years old), were analyzed. Multiple regression examined the relationship between health needs and number of visits in the last year, controlling for the effect of sociodemographic characteristics. Two logistic regression equations were selected to predict heavy (more than seven visits per year) and light (less than two visits) utilization of services. The multiple regression model explained 14.3 percent of the variance in number of visits, with health status perception, disability, reported chronic condition, restriction of activities, and having had a recent accident by far the most important determinants. No familial socioeconomic characteristics, including social class, education, or family size, influenced the extent of use. In contrast to health systems not designed to achieve either universal access according to need or strong primary care, universal access to health services in Catalonia appears to enhance the use of services among children with health needs, regardless of socioeconomic characteristics.     

The perimenopausal woman and her use of health services

This study investigated whether perimenopausal women had higher physician contact rates and a more negative self-assessment of their health than nonmenopausal women in the same 40--50 band. It also examined the relationship between subjective health status, physician contact rates and scores on a set of vasomotor and a set of psychological symptoms. One group of women were more likely to have seen a physician within the previous 2 wk, to report psychological symptoms and to take a negative veiw of their own health. However, perimenopausal women were no more likely to belong to this group than other women. Most perimenopausal women had seen a physician at least once in the preceding 12 mth, but were rarely women with high levels of physician contact.     

The use of health care services by people with diabetes in rural areas

Stapled lung volume reduction surgery (LVRS) has recently been described for treatment of emphysema. Many questions arise regarding physiologic mechanisms of response from surgical treatment of emphysema. The objective of this study was to develop an animal model for the study of lung volume reduction surgery in diffuse heterogeneous emphysema. We hypothesized that elastic recoil would increase, static respiratory system compliance would decrease, and expiratory flows would increase after lung volume reduction surgery in animals with emphysema. In the study, emphysema was induced in 31 New Zealand White rabbits (3-5 kg) with endotracheally aerosalized porcine elastase (10,000-12,000 U). Lateral thoracotomies were performed 4-6 weeks postinduction under general anesthesia and mechanical ventilatory support. Stapled volume reduction was performed on the right lower lobe using a standard multirow pediatric stapler (U.S. Surgical). Pulmonary function tests were performed at baseline (preinduction), before stapling LVRS (postemphysema induction), immediately post stapling LVRS, and 1 week poststapling. Static respiratory system compliance, flow, conductance and forced expiratory flows, and peak flows at 20 and 40 cm3 of exhaled volume were analyzed. Animals were sacrificed 1 week poststapling, and bilateral lungs were harvested for histopathology. Diffuse but heterogeneous pulmonary emphysema was seen in these animals treated with high-dose aerosolized elastase. Static compliance increased, while expiratory flows and conductance decreased after induction of emphysema. Immediately post stapled volume reduction therapy, animals had decreased static compliance. By 1 week following surgery, animals showed increased forced expiratory flows and decreased expiratory resistance, although compliance was similar to preoperative levels. In conclusion, we describe initial results in an animal model of obstructive emphysema suitable for the study of lung volume reduction surgery. Changes in pulmonary function indicate that unilateral lower lobe LVRS increases airway conductance in the rabbits. Findings from LVRS studies in animal models such as this may help explain clinical improvement following LVRS in humans.     

Health status and the use of outpatient mental health services.

Investigated the effects of mental health status—self-reported psychological distress and psychological well-being—on the use of outpatient mental health services, based on mental health data from the Rand Corporation's Health Insurance Survey. Results reveal that probability of mental health care and intensity of treatment provided by mental health specialists increase significantly with increases in psychological distress, independent of insurance plan, physical health, and sociodemographic variables. Results support the validity of self-report mental health surveys. (42 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Cost sharing and the use of ambulatory mental health services.

Used preliminary data from the Rand Corporation's Health Insurance Study to examine expenditures for ambulatory mental health services (MHSs) based on a sample of 4,444 families (at initial enrollment) of the nonelderly, noninstitutionalized civilian population. Selected findings reveal that reducing the level of cost sharing increases the demand for MHSs; the response to cost sharing is roughly the same for ambulatory medical and MHSs. Small deductibles, followed by free care, do not deter the use of ambulatory MHSs. (32 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Costs and use of mental health services before and after managed care

This paper tracks access, utilization, and costs of mental health care for a private employer over nine years during which mental health benefits were carved out of the medical plan and managed care was introduced. Prior to the carve-out, mental health costs increased by around 30 percent annually; in the first year after the change, costs dropped by more than 40 percent; in the six follow-up years, costs continued to decline slowly. This cost reduction was not attributable to decreased initial access, as the number of persons using any mental health care increased following the change. Instead, the cost reduction was the result of (1) fewer outpatient sessions per user, (2) reduced probability of an inpatient admission, (3) reduced length-of-stay for an inpatient episode, and (4) substantially lower costs per unit of service.     

Emergency services use by elderly individuals

The enzyme methanol dehydrogenase (EC 1.1.99.8) from Hyphomicrobium X was used in an attempt to develop a rapid colorimetric test for methanol. The enzyme was stabilized for storage by lyophilization in the presence of the disaccharide trehalose. It was found that the enzyme retained significantly greater activity in the dried state with trehalose than without. The enzyme was partially purified by ammonium sulphate fractionation, after which it was found to be more stable in solution at pH 9 than at pH 7. A procedure is given which involves mixing a defined amount of enzyme with the methanol-containing water together with phenazine methosulphate (PMS), 2-6-dichlorophenol-indophenol (DCPIP) and cyanide, and observing the resultant colour change from blue to yellow if methanol is present. The sensitivity of the procedure is such that 9 mg L-1 of methanol can be readily detected.     

Female veterans' use of Department of Veterans Affairs health care services

OBJECTIVES: As access of women to mental health services has become increasingly important, empirical research has begun to examine the determinants of mental health care utilization across gender. This article examines the effect of being an extreme minority on utilization of Department of Veterans Affairs (VA) health services by female veterans. METHODS: Data were collected on a representative national sample of veterans in 1992 as part of the National Survey of Veterans. These data included information on sociodemographic variables, military service variables, physical health and disability, and health services utilization. The authors examined whether women who used health services in 1992, and who were eligible for VA care, differed from men on the likelihood of using any VA health services and on the likelihood of use of VA outpatient and inpatient health services. In addition, we compared VA health care utilization among subgroups of veterans with physical and mental disorders, and compared self-reported reasons for choice of health care provider, across gender. RESULTS: Results indicated that female veterans were less likely than male veterans to use VA health services. This difference was explained by lower utilization by women of VA outpatient services, since inpatient admission rates were the same across gender. The lower outpatient utilization was specific to women with self-reported mental disorders. Women with physical conditions did not differ from men with similar conditions in their VA outpatient utilization. Finally, men and women did not differ on their reasons for choosing VA or non-VA care. CONCLUSIONS: The authors conclude that extreme gender minority status appears to affect outpatient utilization rates at the VA among women with mental disorders, perhaps because of the more personal or sensitive nature of the services involved. Further research is needed to understand why certain women may be underutilizing VA outpatient services and on the consequences of minority gender status for health service utilization, more generally.     

Social welfare and health services in the Fraylesca Region in Chiapas: the use of prenatal care services

OBJECTIVE: To analyze the use of antenatal care services (ACS) in the Fraylesca Region of Chiapas, Mexico, and to identify groups with lower probability of receiving ACS. MATERIAL AND METHODS: In 1994, a health survey was performed on a random sample of 1,100 households, which compiled sociodemographic information and on the use of ACS during the last pregnancy within the two years previous to the study (n = 297 women from 15 to 49 years of age). The groups with lower probability of receiving adequate ACS (5 or more visits) were identified with a log-linear model. RESULTS: Forty-two percent of women received inadequate ACS (0 to 4 visits). Women with better socioeconomic status had higher probability of using ACS adequately than women with lower socioeconomic status: OR 2.47 (Cl 95% 1.12-5.44). CONCLUSIONS: Results provide evidence of the need to improve the quality of ACS, to support the traditional midwives and to improve living conditions of the population.     

A marketing technique to increase visibility and use of health center counseling services

Marketing a university health-center-based counseling service by giving students promotional items, such as pens, key tags, refrigerator magnets, and self-stick removable note pads bearing telephone numbers and information about counseling services is described. This technique, which resulted in 32% more appointments scheduled and 25% more students being seen during the 1995/96 academic year than had been seen in the 1994/95 academic year, can also be used to increase the use of campus health promotion and medical services.     

Prevalence of depressive symptoms among rural elderly: Examining the need for mental health services.

Reexamined the prevalence of depressive symptoms among 1,724 rural, noninstitutionalized older adults (aged 59–99 yrs) and documented the need for mental health services as they relate to depression and potential barriers to receiving needed services. A telephone survey was conducted in North Dakota, with a random sample drawn from each of 8 human service districts. Instruments included the Geriatric Depression Scale and the CAGE. Results indicate that the prevalence of depression was relatively low. Controlling for potential alcohol abuse, cognitive impairment, and medical problems, the study found that 5% of older adults reported current depressive symptomatology. When using a cutoff score that is likely to correspond to a diagnosis of major depression, the study found a prevalence rate of 1.6%. Of those reporting significant levels of depression, only 27.6% were currently being treated for an emotional problem. The survey data suggested that cost, transportation, and concern about stigma are not major barriers to receiving needed mental health services. Rather, lack of awareness of available services and a lack of routine contact with mental health service providers are important factors that limit service utilization.

Use of health services by Chinese elderly in Beijing

OBJECTIVES: This article provides an inquiry into use of health services by the elderly. METHODS: The authors operationalize models of use with a survey of 350 elderly Chinese. Because the survey involves native Chinese, the empirical test can isolate functional social support as well as "structural" social supports (marriage, living with children). RESULTS: The principal findings comport with prior work: the strongest determinants of the use of health services by the elderly are those that relate to need. In addition, structural social support impacts use but demonstrates complex patterns. CONCLUSIONS: The availability of family support increases physician visits while diminishing the probability of a hospital stay. Increased Western physician use ties to increased use of Chinese physicians and increased hospitalization. Functional social support plays a role as well. Finally, income effects did not play a large role in determining the use of health services among this population.     

Utilisation of health services by aboriginal Australians with diabetes

Diabetes is a major public health problem for Aboriginal Australians. We wished to determine the extent and pattern of health service utilisation by Aboriginal people with diabetes in central Australia. Medical records of all Aboriginal people known to have diabetes (n = 374), identified by a previous study, were examined for attendance to health services in central Australia. All had non-insulin-dependent diabetes. Between January 1984 and December 1986, Aboriginal adults with diabetes were admitted to hospital on 694 occasions, accounting for 10.8% of adult Aboriginal admissions. The crude admission rates were 0.78 and 0.84 per diabetes-year for men and women, respectively. The age-adjusted relative risks for admission, compared with Aboriginal non-diabetic patients, were 2.93 (95% C.I., 2.62-3.26) for men and 2.46 (95% C.I., 2.28-2.66) for women. If admission for conditions associated with diabetes are excluded, the admission rates were similar for the two groups. Infection was the most common reason for attendance to a health service, representing 41.7% and 39.8% of male and female admissions, and 21.8% and 26.3% of male and female outpatient attendances. Aboriginal patients with diagnosed diabetes suffer high morbidity and contribute disproportionately to health system costs.     

Patterns of mental health services provided by HMOs.

Surveyed 145 US health maintenance organizations (HMOs) to determine outpatient mental health services offered, psychologists and other providers used, and practices followed in offering such services. Results show that basic assessment and intervention modalities were available to almost all HMO members. Health education programs (weight control, smoking control, and stress adaptation) were not as broadly available as were the more traditional mental health efforts. Almost all HMOs utilized psychologists as providers, either as employees or consultants; subdoctoral qualifications for employment were accepted by one-fifth of the plans. In most plans, physicians referred patients for psychological services. HMOs based on individual practice association models offered fewer services than either group or staff models. The level of mental health service required for federal qualification is exceeded by plans enrolling 82% of all members. Data did not support the argument that requiring mental health services results in forcing both services and costs upward. It is concluded that the current rate of HMO growth will not provide large numbers of additional jobs for psychologists. (17 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Etiopathogenesis of hemolytic reactions in total artificial heart recipients

Hemolysis in total artificial heart (TAH) recipients was analyzed. From a total of 66 long-term experiments lasting from 30-314 days performed in the Brno Research Center, in 53 animals, the total red blood cell (RBC) count, hematocrit, total hemoglobin, and free plasma hemoglobin were investigated. We could essentially divide the whole group of calves in 2 subgroups. The first subgroup was calves with hemolytic reactions, and the second subgroup was calves without any hemolytic reaction at all. In the first subgroup, hemolysis occurred in 47% of the overall number of animals during extracorporeal circulation (ECC), in 15% during ECC and later periodically during the experiment, in 8% during ECC and then continuously during the experiment, and finally in 10% not during ECC but repeatedly during the experiment. In 20% of the animals from the overall number, hemolysis did not occur at all (second subgroup). These results testify to the great individual differences within 1 breed (Bohemian with a substantial component of Holstein). These differences are further modified by exogenous and endogenous factors. First, the inborn resistance of the RBC membrane and also thrombi formation and the mineralization of the driving diaphragm are very important. The extreme situation of decreased RBC membrane resistance was proved using a calf from another breed, the slow growing Scottish Highland breed, which did not survive 22 days of pumping due to intractable lethal hemolysis. These factors are also indicated by the hemolytic action of some drugs (e.g., Dopegyt) used during the experiment for another reason. Also important are the mechanical forces of pumping, surface moieties of the biomaterial, mineralization of the driving diaphragms, thrombi formation, infection, etc. Essentially, the hemolytic reaction in the TAH recipient has a multifactorial character. Hemolysis is undoubtedly an important factor, which can have a profound impact on the length of survival. The experimental and clinical experiences must be continuously integrated, and conclusions valid for human TAH application must be considered as very important for further TAH experimental and clinical research.
