Factors contributing to patient dumping in Taiwan.

OBJECTIVE: Little research has been carried out to explore the issues surrounding patient dumping outside of the US. This study, therefore, uses a national research survey to examine the factors contributing to patient dumping within Taiwan. METHODS: A self-administered postal survey was undertaken to assess the prevalence of patient dumping in Taiwan, with the study subjects being superintendents of general hospitals. Data from the Bureau of Medical Affairs at the Department of Health in Taiwan were used in conjunction with the Taiwan National Health Insurance Research Database (NHIRD) to obtain estimates of factors potentially contributing to patient dumping. A multiple logistic regression analysis was performed to determine the relationships between the perceived extent of patient dumping occurring within the respondents' healthcare networks, as well as other factors, including the total number of hospitals, total number of hospital beds, the percentages of beds in public, for-profit and teaching hospitals (vis-à-vis all hospital beds), discharges, discharges covered under the case payment system, transferred inpatients, and the perceived degree of competition within each healthcare market. RESULTS: A total of 485 survey questionnaires were distributed, of which 251 were returned, giving a response rate of 51.75%. The responses from 29.9% of the sample group indicated that the perceived extent of patient dumping occurring in their service area was 'serious' or 'very serious'. The regression analysis showed that after controlling for other factors, the superintendents' perceived extent of the patient dumping occurring within their healthcare networks was positively related to the total number of patients covered under the case payment system, the total number of discharged patients, the extent of healthcare market competition and the number of respondent's hospital beds. CONCLUSIONS: We conclude from our findings that, under the National Health Insurance system, patient dumping is a widespread problem within Taiwan's healthcare industry.

Health-related quality of life and health utility for the institutional elderly in Taiwan.

OBJECTIVE: To explore the health-related quality of life (HRQOL) and health utility in an institutional elderly population. METHODS: Four hundred sixty-five elderly persons living in long-term care institutions in Taiwan were interviewed using Taiwan's abbreviated version of the World Health Organization Quality of Life (WHOQOL-BREF), rating scale (RS) and the Time-Trade-Off (TTO) utility measurement. RESULTS: The WHOQOL-BREF showed acceptable internal consistency (alpha range: 0.75-0.80 across domains) and validity. The sexual activity facet had the lowest response rate. Educational level, number of chronic diseases, physical performance, and number of caregivers had significant (p < 0.05) impacts on the domain scores of the WHOQOL-BREF. Physical performance had the strongest impact on the physical domain (R2 = 0.40) and accounted for significant percentages of the variance on the other three domains (R2 = 0.06-0.13). The mean RS score (score 0-100) was 61.3 +/- 16.2 (mean +/- SD). The mean TTO utility (score 0-1) was 0.92 +/- 0.22. CONCLUSIONS: Results indicate that the WHOQOL-BREF, excepting the sexual activity item, is useful for evaluating HRQOL of conscious elderly in institutions. The validity of TTO utility for studying the institutionalized elderly needs further evaluation.

WHOQOL-BREF as predictors of mortality: a two-year follow-up study at veteran homes.

The main purpose of this study was to evaluate the effectiveness of the brief version of the World Health Organization Quality of Life (WHOQOL-BREF) questionnaire as a predictor of mortality amongst the elderly. A total of 689 male residents of veteran homes, all above the age of 65 years, were randomly selected in 2001. The Taiwan version of the WHOQOL-BREF was administered as the baseline, with each of these subjects being interviewed and subsequently followed up for mortality until the end of 2003. Data on self-reported global health, life satisfaction, medical status, physical performance and health behavior was also collected. Following the death of 105 of the 689 subjects during the 2-year follow-up period, the relative risk (RR) of death was subsequently assessed using Cox's proportional hazard regression analyses. After adjusting for other predictors (age group, chronic diseases, emergency visits, hospitalization, physical performance, regular exercise, self-reported global health and life satisfaction), almost all of the WHOQOL-BREF items and domains failed to predict mortality; the one exception was working capacity levels (score 1-2 vs. score 4-5) which, after adjusting for other predictors, did demonstrate the ability to predict mortality (RR = 1.96, p < 0.05).

Length of stay and costs for asthma patients by hospital characteristics--a five-year population-based analysis.

This study sets out to explore the relationship between hospital characteristics, asthma length of stay (LOS), and costs per discharge. The study adopts hospitalization data from the Taiwan National Health Insurance Research Database covering the period from 1997 to 2001. Study subjects were identified from the database by principal diagnosis of asthma or asthmatic bronchitis, with a total of 139,630 cases being included in the study. Multiple-regression analyses were performed to explore the relationship between LOS, costs per discharge and hospital characteristics, adjusting for age, gender, and discharge status of patients, as well as complications or comorbidities. The regression analyses showed that, compared with district hospitals, medical centers and regional hospitals have longer and more statistically significant LOS, as well as higher costs. Hospitals operating on a for-profit basis have shorter LOS and lower costs than public and not-for-profit hospitals. This study shows the existence of wide variations in LOS and costs per discharge for asthma hospitalizations, between the various types of hospitals in Taiwan.

Using a population-based database to explore the inter-specialty differences in physician practice incomes in Taiwan.

Gaining an understanding of the distribution of physician incomes between different medical specialties could assist policymakers to predict the future medical manpower supply. The purpose of this study is to examine the differences in medical specialty-specific gross practice incomes between office-based physicians in Taiwan. The primary data source for the study, which includes 7444 office-based physicians, was provided by the Taiwan Department of Health, with the dependent variable of interest to this study being the annual gross income of physician practices, whilst the independent variable is physician specialty. The study controlled for physicians' age, gender, specialty-board status, type of practice, location of clinic and urbanization level of the community in which the practice was located. Multivariate regression analyses were carried out to explore the relationship between physician specialty and gross practice income. This study finds a significant relationship between the annual gross income of physician practices and the physician's medical specialty (P < 0.001). Of all physicians, those specializing in rehabilitation and orthopedics had the highest gross practice incomes; conversely, obstetricians and gynecologists had the lowest gross practice incomes. The regression analyses demonstrated that after adjusting for socio-demographic and professional characteristics, gross practice incomes of physicians were significantly related to their medical specialty. This study concludes that differences in the gross practice incomes of physicians were significantly related to medical specialties. Those physicians specializing in procedure-based specialties, such as rehabilitation and orthopedics, had higher practice incomes than their counterparts in other more diagnosis-oriented specialties such as family practice and pediatrics.

Association of hospital ownership with patient transfers to outpatient care under a prospective payment system in Taiwan.

Case payment, a prospective payment system akin to diagnosis-related groups (DRGs) has in-built incentives for hospitals to transfer inpatients to their own ambulatory care units following early discharge. This study used nation-wide inpatient claims data on a total of 100,730 patients treated in 2000 in (Taiwan): cesarean section (59,364 cases), femoral/inguinal hernia operation (18,675 cases), and hemorrhoidectomy (22,691 cases), all reimbursed by case payment, to explore the relationship between hospital ownership and patient transfers to outpatient treatment. For all three diagnoses, for-profit (FP) hospitals not only had lower lengths of stay (LOS) compared to public hospitals, but also showed very high odds of patient transfer to their own outpatient units, after controlling for institutional variables, (hospital level, teaching status, and geographic location), hospital competitive environment (the Herfindal-Hirschman index), and patient variables (gender, age, length of stay, and number of secondary diagnoses, a proxy for severity of illness). Similar, though slightly lower odds were observed with not-for-profit (NFP) hospitals relative to public hospitals. The findings support the property rights theory, suggesting that in Taiwan, institutional profit maximization motives may be driving patient transfers under the case payment diagnoses, rather than medical care needs. In NFP hospitals, their physician compensation mechanism, driven largely by care volumes provided by each physician, appears to be driving the disproportionately greater likelihood of patient transfer to outpatient care.

Association between maternal age and the likelihood of a cesarean section: a population-based multivariate logistic regression analysis.

BACKGROUND: A majority of studies examining the relationship between advancing maternal age and the likelihood of cesarean section (CS) use data from regional samples or from a limited number of medical institutions. This study uses population-based data from Taiwan to explore the relationship between maternal age and the likelihood of a CS. METHODS: The National Health Insurance Research Database (NHIRD) on registries of medical facilities and board-certified physicians and monthly claim summaries for inpatients were used. In total, 502 524 singleton deliveries were included in the study. Multivariate logistic regressions were performed with the presence of CS as the dependent variable and maternal age (<20, 20-29, 30-34 and >34 years) as the independent variable. The study controlled for maternal indications, institution characteristics, maternal requests and attending physician characteristics. RESULTS: CS rates for the age groups <20, 20-29, 30-34 and >34 years were 17.7, 27.4, 37.4 and 47.5%, respectively. The regression analyses consistently showed that the likelihood of a CS significantly increased with advancing maternal age within each category of complication after adjusting for medical institution characteristics and characteristics of the attending physician. CONCLUSIONS: This study found that, after adjusting for maternal indications, and healthcare institution and physician characteristics, there was a significant relationship between advancing maternal age and an increased likelihood of a CS. This finding, together with the high CS rate of 32.1% in Taiwan, one of the highest reported in the world today, highlights an imperative need to devise interventions to reduce the frequency of CSs.

Preferences of the elderly and their primary family caregivers in the arrangement of long-term care.

BACKGROUND AND PURPOSE: Long-term care policies and networks in Taiwan are still in the early stages of development and as such it is important to establish comprehensive care models which clearly define the needs of the elderly and their family members. This study examined the preferences of the elderly and their primary family caregivers in long-term care arrangements. METHODS: Using multi-stage sampling, a total of 1180 subjects (n = 593 elderly people [age > or = 65 years] and n = 587 caregivers) from 7 counties/cities in the north of Taiwan were interviewed by local public health nurses. RESULTS: Home care was the first choice for both elderly people and their primary caregivers (59.2% of both groups combined). Institutional care was considered the second choice; however, only 9.2% found this choice acceptable. Community-based care was the least preferred mode of long-term care (4.2%). Among the sample subjects, elderly people born in China, those not living in the Taipei metropolitan area, and those not receiving a financial subsidy from the government, indicated that they would be more inclined to accept institutional care. All other elderly people between the ages of 65 and 74 years indicated greater preference for community-based care. Primary caregivers born in China, those with only an elementary school level of education, and those with previous unpleasant experiences in caring for the elderly were more inclined to accept community and institutional care. CONCLUSIONS: Most elderly people and their primary family caregivers preferred home care. This study also revealed that previous experiences with care for the elderly, educational level, and socioeconomic status were important factors influencing preferences for long-term care arrangements.
