Screening for asthma and associated risk factors among urban school boys in Abha city.

OBJECTIVE: The objective of the present study was to measure the prevalence of asthma and asthma-related symptoms among male school children in Abha City and to determine some of the possible risk factors influencing its occurrence. METHODS: A randomly selected sample of 4300 male school children aged 7 to 15 years in Abha were subjected to a previously validated questionnaire for asthma to be completed by parents. Asthma was identified based on the Rush Medical College and International Study of Asthma and Allergies in Children questionnaire. Information of asthma family history, asthma related symptoms, and other atopic conditions, smokers in the family, pets ownership and monthly family income were collected. RESULTS: The overall prevalence of asthma was 9% (95% Confidence Interval: 7.73%-9.67%). Doctor-diagnosed asthma was reported by 4%, exercise-induced asthma by 4% and wheeze in the past year by 8%. Multiple logistic regression analysis showed that positive family history of atopic condition (Odds Ratio=437.11, P<0.001), pets ownership (Odds Ratio=2.91, p<0.001), and lower monthly family income (Odds Ratio=2.00, P<0.02) were significant factors influencing the development of asthma. CONCLUSION: In conclusion, the screening methodology adopted in this study could be applied for all children at the beginning of the school year, being simple and non-invasive measure. The prevalence of asthma in school children in Abha is greater than that reported from most developing countries and closer to the rates reported in developed countries. Avoidance of pets ownership at home, improving social class and premarital counselling for atopic persons are all recommended.

PACS support: the radiology approach.

In 1999, Rex Healthcare, a 394-bed facility located in Raleigh, N.C., faced a growing problem. The radiology department was performing a total of 130,000 procedures a year, running out of space to store the film, and having trouble managing the file room. While the IT department was focused on the Y2K scare, radiology forged ahead with a plan to implement PACS on its own at Rex Hospital. Rex had installed a mini-PACS system for ultrasound in 1996, but there was no internal support for the system's hardware or software. Being the first in the area to implement PACS, Rex wasn't able to recruit anyone locally to support the system, so they decided to take two areas that PACS had a great impact on and use their own people. The director of radiology asked the RIS analyst and the Film Library manager, both of whom were registered technologists, to implement and support the PAC system. The key to PACS support is not computer knowledge, although it helps. The key is to understand the radiology department as a whole and the workflow from within, which makes it hard to fully support from an IT perspective. The current PACS team at Rex is composed of a PACS analyst, system support specialist and an electronic imaging center manager. When we went live with PACS, it was obvious that not all of the existing file room personnel would make the technology leap, which they realized themselves. We didn't push anybody out, but we did raise the bar of expectations. By redefining job descriptions and having the EITs (electronic imaging technologists) become more involved, increased respect was quite evident among the hospital staff. The clerks that once only hung and filed films are now troubleshooting CD burners, teaching physicians the PACS, and filming necessary exams. The final key to success is to take ownership of your system. By taking ownership, I mean that a PACS team should be established to do troubleshooting and first-line support, know the servers and application, and feel comfortable performing daily checks and tasks. Being an advanced radiology PACS site in our area, we have become an important facility for site visits. We take site visits very seriously, and have composed a package that includes information about the hospital, network/modality diagrams, EIT job descriptions, PACS information and various time studies that we have completed since going firmless. An administrator with a vision and strong support from within will get a PACS up and running, but ongoing upkeep requires a team that is dedicated to the success of the project. By taking ownership of the system and following the keys to success, a department has the ability to reengineer radiology workflow not just in the hospital, but in the community as well.

Echinococcosis on the Tibetan Plateau: prevalence and risk factors for cystic and alveolar echinococcosis in Tibetan populations in Qinghai Province, China.

Infections by larval stages of tapeworms of the genus Echinococcus (echinococcosis or hydatid disease) are zoonotic infections of major public health importance throughout much of the world. Humans become infected through accidental ingestion of eggs passed in faeces of canid definitive hosts. Tibetan populations of China have some of the highest documented levels of infections by both Echinococcus granulosus and E. multilocularis, the causes of cystic and alveolar echinococcosis, respectively. In this study we measured the prevalence of cystic (CE) and alveolar (AE) echinococcosis disease in Tibetan communities in Qinghai, Province, China, and identified putative risk factors for both infections in these communities. 3703 volunteers in three predominately Tibetan counties of Qinghai were surveyed between June 1997 and June 1998. Parasitic lesions were diagnosed by imaging of characteristic space-occupying lesions in abdominal organs (ultrasound) or the lungs (radiographs). Specific serodiagnostic assays (Dot-ELISA and Em2-ELISA) were performed on sera of positively imaged subjects to further distinguish the disease agent. All participants completed a questionnaire documenting age, sex, education level, occupation, lifestyle (nomadic or settled), slaughter practices, drinking water source, hygienic practice and association with dogs. Data were analyzed using SAS version 8. 6.6% of the volunteers had image-confirmed infection with E. granulosus (CE) and 0.8% had E. multilocularis (AE) infection. The significant univariate factors for echinococcal infection (both CE and AE) included livestock ownership, Tibetan ethnicity, female gender, low income, herding occupation, limited education, water source, age greater than 25 years old, poor hygienic practices, offal disposal practices and dog care. Multivariate analysis revealed that livestock ownership was a significant risk factor for both forms of the disease, as well as age greater than 25 years, female gender, herding occupation, and being nomadic (vs semi-nomadic or settled). No additional significant risk factors were identified among the 344 nomadic participants. Being female and being older than 25 years of age were significant factors among the 1906 semi-nomadic participants. Among the 1445 settled participants, allowing dogs to sleep indoors was statistically significant. Issues such as inadequate assessment of animal ownership, selection bias, disease misclassification, and loss of information may have led to reduction in strength of some risk factor associations and need to be addressed in future epidemiologic analysis of echinococcosis in this population.

Length of hospital stay of Medicare patients in the post-prospective-payment-system era.

This study examines factors determining hospital length of stay (LOS) for Medicare patients in the post-prospective-payment-system (PPS) era according to type of ownership, geographical region, bed size, and financial performance. The study design includes a number of economic and financial variables. In the empirical findings, the following factors are significant in determining hospital LOS of Medicare patients: hospital size, type of ownership, profitability, teaching status, and competition. Other studies have examined factors influencing length of hospitalization; however, none of these studies investigates the effect on LOS of a change in the type of hospital ownership. Furthermore, this study uses more recent and comprehensive data than in the current literature.

New evidence of the prevalence and scope of physician joint ventures.

Physician ownership of health care businesses (outside their own practice) to which they refer patients has attracted considerable attention in the medical literature, in the media, and from federal and state policymakers. Despite the concerns raised about these ownership arrangements, known as joint ventures, the prevalence and scope of joint ventures involving physicians is not well documented. This report examines the prevalence and scope of physician joint ventures in Florida based on data collected under a legislative mandate. Our results indicate that physician ownership of health care businesses providing diagnostic testing or other ancillary services is common in Florida. While this conclusion is based on our comprehensive survey of health care businesses in Florida, it is at least indicative that such arrangements are likely to occur elsewhere. We find that at least 40% of Florida physicians involved in direct patient care have an investment interest in a health care business to which they may refer their patients for services; over 91% of the physician owners are concentrated in specialties that may refer patients for services. About 40% of the physician investors have a financial interest in diagnostic imaging centers. The estimates reported here indicate that the proportion of referring physicians involved in direct patient care who participate in joint ventures is much higher than previous estimates suggest.

Why we need the independent sector: the behavior, law, and ethics of not-for-profit hospitals.

Among the major forms of corporate ownership, the not-for-profit ownership form is distinct in its behavior, legal constraints, and moral obligations. A new empirical analysis of the American Hospital industry, using eleven years of data for all urban general hospitals in the country, shows that corporate form accounts for large differences in the provision of specific medical services. Not-for-profit hospitals systematically provide both private and public goods that are in the public interest, and that other forms fail to provide. Two hypotheses are proposed to account for the findings, one legal and one moral. While no causal claims are made, not-for-profit hospital behavior is consistent with the behavior required by law and morality. The moral argument, developed as a preliminary theory of not-for-profit ethics, also provides a potential reason to prefer not-for-profit hospitals. The findings provide a new justification for the not-for-profit tax exemption for hospitals, and also suggest new uses for ownership categories as regulatory tools.

Increasing appointment compliance through telephone reminders: does it ring true?

This study evaluated the effectiveness of telephone reminders on appointment-keeping in young people treated for gonorrhea. Compliance with scheduled follow-up was recorded for a total of 339 patients during three two-week periods, namely, initial baseline phase, intervention phase during which attempts were made to remind the patients by telephone, and repeat baseline phase. There was no overall improvement in compliance with follow-up during intervention (31%), compared to baseline (32%). However, data from the intervention phase revealed a significantly higher rate of appointment-keeping for those patients who were contacted (44%) than for patients who were not reachable (20%). Furthermore, when we reanalyzed the data as a function of telephone ownership for all patients who did not receive a reminder, return rates were significantly higher for patients owning telephones (32%) than for those denying phone ownership (18%). Thus, we conclude that the likelihood for appointment compliance was related more to sociobehavioral factors reflected in telephone ownership than to the telephone reminders.

Current trends in physicians' practice arrangements. From owners to employees.

OBJECTIVE: To examine current trends in practice organization among postresident patient care physicians in the United States. DESIGN AND SETTING: The American Medical Association's Socioeconomic Monitoring System (SMS), a series of periodic surveys of nationally representative samples of nonfederal postresident patient care physicians. Physicians were divided into 3 categories based on the organization of their main practice. They were classified as employee physicians if they had no ownership interest in their practice, as self-employed solo physicians if they were in 1-physician practices in which they had an ownership interest, and as self-employed group physicians if they were in multiple-physician practices in which they had an ownership interest. PARTICIPANTS: Nonfederal, postresident patient care physicians who provided more than 47 000 responses to SMS surveys between 1983 and 1994. MAIN OUTCOME MEASURE: The proportion of nonfederal postresident patient care physicians who were employees between 1983 and 1994. RESULTS: Between 1983 and 1994, the proportion of patient care physicians practicing as employees rose from 24.2% to 42.3% (P<.001), the proportion self-employed in solo practices fell from 40.5% to 29.3% (P<.001), and the proportion self-employed in group practices fell from 35.3% to 28.4% (P<.001). Most of these changes occurred in the latter half of the 12-year period. These trends, which are evident in virtually every segment of the patient care physician population, are especially prominent among young physicians. The growing proportion of employee physicians is associated with increases in the earnings of employee physicians relative to those of self-employed solo physicians. CONCLUSIONS: Current trends in the US health care system are rapidly changing the career opportunities of patient care physicians and, hence, physicians' choice of practice arrangement.

Evaluation of a four-year bicycle helmet promotion campaign in Quebec aimed at children ages 8 to 12: impact on attitudes, norms and behaviours.

OBJECTIVE: This study evaluated a four-year bicycle helmet promotion campaign. METHODS: Children's attitudes, social norms, intentions to wear a bicycle helmet as well as helmet ownership were measured. Evaluation was based on a pre-experimental static group comparison design repeated at two (1991) and four years (1993) after implantation, with a non-randomized control group. 3,424 students completed a self-administered questionnaire (experimental: 2,097, control: 1,327). RESULTS: The program had a significant impact on helmet ownership (1989: 4%; 1991: 26%; 1993: 56%). The program was the principal predictor of high intention to use a bicycle helmet. Time was the principal predictor of ownership with exposure to the program being the next predictor. CONCLUSION: This study showed that time is an important factor in bicycle helmet acquisition, and that a long-term community-based program can accelerate the process of adopting this behaviour.

Inpatient childhood asthma treatment: relationship of hospital characteristics to length of stay and cost: analyses of New York State discharge data, 1995.

BACKGROUND: There is increasing pressure to optimize asthma treatment efficiency. It is possible that hospital characteristics influence such efficiency. OBJECTIVE: To examine the association of selected hospital characteristics with cost and length of stay (LOS) among pediatric patients with asthma after adjusting for patient characteristics. DESIGN: Secondary analysis of 1995 hospital discharge data in the state of New York. SUBJECTS: Nineteen thousand six hundred eighty-eight patients aged 1 to 17 years with asthma discharged from 206 acute care hospitals in New York in 1995. MAIN OUTCOME MEASURES: Length of stay and hospital cost. ANALYSIS: Hospitals were described with respect to teaching status and ownership. The differences in the distribution of children within each hospital type were assessed by chi(2) tests. In multivariate analyses, hierarchical models were constructed to analyze cost and LOS, adjusting for both hospital- and patient-level covariance. RESULTS: Asthma severity did not meaningfully differ by hospital ownership and teaching status. Public and teaching hospitals had more minority and Medicaid patients. After adjusting for patient- and hospital-level covariates and for the hierarchical nature of the data, there were no statistically significant differences between public and private hospitals in mean cost or LOS. Adjusted mean LOS in teaching hospitals was not significantly shorter, while costs were significantly but not meaningfully greater ($2459 vs $2271; P<.001). CONCLUSION: Hospitals providing medical education to pediatricians and safety net care do so without increasing LOS or cost of care for pediatric asthma.

The role of constituency groups in policy formulation: items for a health services research agenda.

The Veterans Administration medical care system functions within a larger VA services program that has as its direct constituency many organized veterans' groups. The VA system is viewed from the larger perspective of consumer representation in its direction through three effective functions of consumer representation: ownership, control, and oversight. In the VA the Congress and the veterans' groups perform these functions with varying levels of impact on the system. While veterans feel a measure of ownership of the medical care system, they have little voice in its actual operation. Research is needed to describe more fully fully the actual role of the veterans-client in the system and to explore the possibility that aspects of the system may be adopted outside.

Moral strangers and the health care market.

In order to reflect on the morality of the health care market this paper critiques some of H.T. Engelhardt's presuppositions. Engelhardt has created the vivid term 'moral stranger' and suggested that there can be a 'morality of moral strangers'. However his position relies either on certain necessary presuppositions which he leaves unmentioned or on presuppositions that are--in a strict sense--not moral ones. Engelhardt advocates the market economy as the guiding principle of health care, and claims that the market needs no moral presuppositions. But when the preconditions of a functioning market are examined it turns out that a functioning market requires property and ownership, and that property and ownership are moral institutions. Therefore the application of the idea of the market to health care undoubtedly has morally serious consequences: most important, the difference between commodities and human beings is obscured.

The market for residential and day schools for children with severe emotional disturbance.

This article describes the market for residential and day programs that provide education and treatment services on site for children with severe emotional disturbance (SED) in terms of the market's size, cost, and ownership mix. As policymakers encourage integration of services across sectors, this research fills a gap in the mental health services literature by providing a baseline of information on facilities from the education sector. Data are used from a national, stratified sample survey of separate day and residential schools for children with handicaps conducted by the Department of Education. There are 1,523 facilities providing educational and treatment services to 117,720 children with SED. Over half of the facilities are nonprofit, one-third are public, and less than one-tenth are for-profit. These programs represent a significant market of services for children with SED. Substantial differences in cost exist across ownership form that cannot be attributed to differences in size of facility or case mix of children enrolled.

Measuring hospital performance. A non-parametric approach.

In this paper a technique for assessing the relative performance of firms is introduced and applied to a sample of hospitals in California. Hospitals are compared on the basis of their relative technical efficiency. The reference technology is constructed from observed outputs and inputs (including physicians) using programming techniques, and efficiency is assessed relative to the frontier of the technology using measures similar to those suggested by Farrell. The technique used here imposes no prespecified functional form, allows for multiple outputs and inputs (allowing for differences in case mix), and yields information on the productive performance of individual hospitals. This technique can also be used to determine whether different types of hospitals use different technologies. Our results, although illustrative rather than definitive, suggest that ownership affects 'efficiency' as measured here: public and NFP hospitals have 'different' best practice frontiers, and public hospitals appear to use relatively fewer resources. These results could reflect differences in quality of care by ownership.

Rural community hospital closure and health policy.

Closure of rural community hospitals in the U.S.A. is a growing and important trend with serious implications for rural communities and the overall health care system. This study analyzes characteristics of all U.S. rural hospitals that closed between 1980 and 1986. Variables correlated with risk of closure--for-profit ownership status, non-government not-for-profit ownership status, number of other hospitals in the county, presence of a nursing or other long-term care unit, few facilities and services offered, lack of accreditation by the Joint Commission of Accreditation of Hospitals, lack of membership in a multihospital system--indicate that a rural hospital's survival depends upon its ability to compete and adapt in a volatile, competitive health care marketplace. five policy options are discussed: changes in Medicare payments, expansion of the number of hospitals designated as sole Community Hospitals, the use of swing beds, establishment of state offices of rural health, and short-term federal and state grants. Allowing hospitals the flexibility to adapt and compete, while ensuring adequate quality health care to rural residents, is suggested as the priority in rural health policy.

A model for an outpatient imaging center.

U.S. federally imposed efforts to regulate joint venturing are a result of certain physician strategies to circumvent anti-kickback statutes by investing in clinics, labs, and facilities for self-referral. This article addresses the ethical debate on physician ownership, MRI as an evolving modality, the 1989 Ethics in Patient Referrals Act and the subsequently released "safe harbors," and finally, describes an existing model for physician/hospital ownership in an outpatient MRI facility.

The life cycle of crime guns: a description based on guns recovered from young people in California.

STUDY OBJECTIVE: We describe the life cycle of crime guns recovered from young people-the movement of those guns from manufacture to criminal use-and identify associations between the characteristics of those guns and their possessors, purchasers, sellers, and places of origin. METHODS: This is a cross-sectional study of data from gun ownership tracing records compiled by the Bureau of Alcohol, Tobacco, Firearms and Explosives for 2,121 crime guns recovered in California from persons younger than 25 years and traced in 1999. Purchaser and seller data for handguns were updated when possible by linking to California handgun sales records. RESULTS: The 2,121 traced guns were recovered from 1,717 young people. Guns recovered from persons aged 21 to 24 years were most frequently also purchased by persons aged 21 to 24 years; those recovered from persons younger than 18 years were most often purchased by persons aged 45 years or older. Small-caliber handguns made up 41.0% of handguns recovered from persons younger than 18 years but 25.2% of handguns recovered from persons aged 21 to 24 years. The median time from sale to recovery (commonly called time to crime) for all guns was 6.4 years (interquartile range 2.7 to 12.4 years). A time to crime of less than 3 years, suggesting deliberate gun trafficking, was observed for 17.3% of guns recovered from persons younger than 18 years but 34.6% of guns recovered from persons aged 21 to 24 years. Ten retailers who sold 10 or more traced guns accounted for 13.1% of all guns traced to a retailer. Handguns whose purchaser and possessor were the same person were more likely than others to be large-caliber semiautomatic pistols (29.3% and 11.7%, respectively); their median time to crime was 0.2 years (69 days). CONCLUSION: Analysis of crime-gun ownership traces reveals patterns that may help refine gun violence prevention efforts and render them more effective.

A sociodemographic analysis of inpatient oral surgery: 1989-1994.

This retrospective study was designed to assess the socioeconomic status of patients who underwent inpatient oral operations from 1989 to 1994 in the area covered by the West Midlands Regional Health Authority and to compare the distribution with those people treated by other specialties. A total of 4,926,438 hospital inpatient finished consultant episodes within 56 specialties that were recorded on the Hospital Episode Statistics database, of which 61,360 (1.25%) were dental (coded as oral surgery, restorative dentistry, orthodontics, and paediatric dentistry). The main outcome measure was the socioeconomic status of patients as assessed by the Townsend score (a measure of material deprivation that covers car ownership, home ownership, overcrowding, and unemployment). There was a highly significant correlation between the use of all inpatient services and social deprivation (R2 = 0.98, P < 0.001). This observation was consistent across all specialties except oral surgery, in which the correlation was reversed (R2 = 0.69, P < 0.001), indicating that patients who avail themselves of inpatient oral surgery are from a higher socioeconomic group. The application of a deprivation index to hospital episode data will enable purchasers and providers to measure more accurately the impact of their services on groups within the community.
