Implementation Of National Health Insurance Research Articles

Re-launch of the South African Society of Medical Managers (previously known as the Medical Administrators Group)

Medical management is a recognised specialty in many developing and developed countries, including Australia, India, New Zealand, Pakistan and Sri Lanka. In South Africa it was recognised as a sub-specialty in the 1990s, but this is no longer the case. The South African Society of Medical Managers, in close collaboration with the Division of Medical Management of the College of Public Health Medicine of South Africa, has been working to re-establish the specialty of medical management in South Africa. Well-trained specialist medical managers would play a significant role in the effective and efficient implementation of National Health Insurance and primary healthcare re-engineering through the practice of evidence-based health care, clinical economics and administrative medicine.

Gender differences in public perceptions on National Health Insurance

Implementation of National Health Insurance (NHI) commenced recently. With the promise of addressing drastic inequalities in the health sector, NHI has the potential to positively transform the health system . In particular, NHI could have a significant positive impact on females, who are disadvantaged under the current system, with higher rates of poor health and lower rates of medical scheme membership compared with males. Despite NHI's transformative potential, however, the public discourse on NHI as portrayed in the media suggests that it is an unpopular policy. The evidence presented in this paper is to the contrary. To assess the general public's opinion on NHI and to explore gender differences in perceptions. This paper reports on findings from a 2010 cross-sectional nationally representative survey of the South African population that assessed social attitudes, including perceptions on NHI. Sex-disaggregated data were analysed in SPSS version 20. There is broad public acceptance of NHI, indicating that an overwhelming majority of South Africans would prefer an NHI system to the current two-tiered system. Support for NHI has increased since similar studies in 2005 and 2008, with the simultaneous growth of public discourse on the policy. More females than males support NHI, reflecting the potential of the NHI system to have a positive impact on gender equality and the health of women and girls.

National Health Insurance program and life satisfaction of the elderly

Objectives: To ensure people's fundamental right to adequate medical care, universal health insurance is given a high priority in contemporary public policy. This article investigates the effects of the introduction of Taiwan's National Health Insurance (NHI) on life satisfaction within the elderly segment of the population. Methods: A longitudinal data set including 610 males and 430 females aged 65 or above was constructed from the Survey of Health and Living Status of the Elderly in Taiwan. A difference-in-differences-in-differences model was employed and estimated by the random-effect regression method. Results: The effects of NHI on life satisfaction are different by gender. Compared to the change in life satisfaction between the previously uninsured and insured elderly men, the introduction of NHI had a larger effect of 4.330 points on reducing the disparity in life satisfaction between previously uninsured and insured elderly women. Education, living arrangements, lifestyle, social activities, geographic location, and urbanization level are also important determinants for life satisfaction among the elderly. Conclusions: Although NHI is designed to ensure equality for accessing health care, the implementation of NHI has also improved the subjective well-being of the elderly, with a larger improvement for the elderly women. The post-NHI disparity reductions in life satisfaction between the previously uninsured and insured are significantly greater among elderly women. Our analysis of Taiwan's experience should provide a valuable lesson to countries that are in the initial stages of proposing a universal health insurance program.

A case study of applying LRFM model in market segmentation of a children’s dental clinic

Dental services marketing has become more and more crucial in Taiwan after Taiwan’s entrance of the World Trade Organization and the implementation of National Health Insurance (NHI) program. This paper develops an extended RFM (recency, frequency, and monetary) model, namely LRFM (length, recency, frequency, and monetary) model, by adopting self-organizing maps (SOM) technique for a children’s dental clinic in Taiwan to segment its dental patients. Twelve clusters are recommended for the overall 2258 patients. The average values of LRF are computed for each cluster and the overall patients, excluding monetary covered by NHI program. The values of LRF variables for each cluster greater than those of the overall average are identified. The results show that three clusters having the above average LRF values (454 patients) can be viewed as core patients.

National Health Insurance: implications for medical practice

The Green Paper on National Health Insurance (NHI) was published on 12 August 2011. It is open for public comment until 30 December 2011. The Green Paper contains the draft proposals of government for NHI. Once adopted by Parliament, it will be called a White Paper, and will then constitute official government policy. Although the Green Paper only contains high-level proposals, it provides a framework for the implementation of NHI. This article briefly reviews these proposals, and their implications for medical practice.

Evolution in intergenerational exchanges between elderly people and their grandchildren in Taiwan; data from a multiple round cross-sectional study from 1993 to 2007

BackgroundThis study aimed to evaluate social evolution in Taiwan in recent decades using the changing pattern of care provided by grandparents for their grandchildren as an indicator.MethodsData from the second, fourth and sixth wave surveys of the Study of Health and Living Status of the Middle-Aged and Elderly in Taiwan were used for the analysis. This survey collected individual characteristics, including age, gender, education, ethnicity, dwelling place, living with partners, co-resident with children, employment status, self-reported health status and their provision of care for their grandchildren. Information about the attitudes toward National Health Insurance (NHI) was further collected in a questionnaire of 1999 following the implementation of NHI in 1995. By elders, we mean persons 60 or more years old. By grandchildren, we mean persons under 16 years of age. First, changes in individual characteristics were compared during these study periods (chi-square test). Then the logistic regression was performed to determine how significantly elders' grandchild-care behavior was associated with their individual characteristics.ResultsThe percentage of elders providing grandchild care increased from 7.7% in 1993 to 13.6% in 1999, and then to 19.4% in 2007. By analysis, significant association was found between behavior in taking care of grandchildren and individuals of lower age, grandmothers, those living with partners or co-residing with children, those unemployed and those with better self-reported health status. And the effect of year was confirmed in the multivariable analysis.ConclusionsThis study pointed out the changing pattern of elders' behavior in taking care of their grandchildren as the main indicator and their related individual characteristics. We argue the need for improving social security policies in an ageing society. We suggest that the interaction between population policies and those of social welfare, including policies for health care and childcare, should be carefully evaluated.

Comparison Between Canadian Triage and Acuity Scale and Taiwan Triage System in Emergency Departments

Since the implementation of National Health Insurance in Taiwan, Emergency Department (ED) volume has progressively increased, and the current triage system is insufficient and needs modification. This study compared the prioritization and resource utilization differences between the four-level Taiwan Triage System (TTS) and the standardized five-level Canadian Triage and Acuity Scale (CTAS) among ED patients. This was a prospective observational study. All adult ED patients who presented to three different medical centers during the study period were included. Patients were independently triaged by the duty triage nurse using TTS, and a single trained research nurse using CTAS with a computer support software system. Hospitalization, length of stay (LOS), and medical resource consumption were analyzed by comparing TTS and CTAS by acuity levels. There was significant disparity in patient prioritization between TTS and CTAS among the 1851 enrolled patients. With TTS, 7.8%, 46.1%, 45.9% and 0.2% were assigned to levels 1, 2, 3, and 4, respectively. With CTAS, 3.5%, 24.4%, 44.3%, 22.4% and 5.5% were assigned to levels 1, 2, 3, 4, and 5, respectively. The hospitalization rate, LOS, and medical resource consumption differed significantly between the two triage systems and correlated better with CTAS. CTAS provided better discrimination for ED patient triage, and also showed greater validity when predicting hospitalization, LOS, and medical resource consumption. An accurate five-level triage scale appeared superior in predicting patient acuity and resource utilization.

Private practice: adapt or die.

To the Editor: All doctors in private practice should be well aware that the National Health Insurance (NHI) scheme is a clear and inevitable danger. To judge from the comments of ANC luminaries, the government will probably do its usual bull-in-a-china-shop act by ramming the bill through parliament without much regard for the opinions of other stakeholders. And if the government’s past form in handling health care is anything to go by, implementation of NHI in South Africa is likely to be a disaster.

Will private health insurance schemes subscriptions continue after the introduction of National Health Insurance in Uganda?

Uganda is currently designing a National Health Insurance (NHI) scheme, with the aim of raising additional resources for the health sector. Very little was known about the health insurance market in Uganda before this study, so one of our main objectives was to investigate the nature of the private health insurance market in Uganda and the opinions of various stakeholders on NHI, with the view to establish the impact of NHI implementation on the existing PHI. Specifically, we aimed to gather the opinions of employees and employers on the likely impact of NHI on their PHI schemes. We conducted interviews with health insurance providers, and a sample of employers and employees in Kampala, using structured questionnaires and analysed quantitative data using STATA. Qualitative data was analysed through grouping of emerging themes. Community-based health insurances were excluded from the study. Health insurance and/or prepayment schemes are offered by a handful of organisations or private health providers, mainly in Kampala and cover a relatively small percentage of Uganda's population. The premiums charged and the benefit packages offered by the different agencies vary widely. There are 2 health insurance agencies, 2 HMOs and about 5 or more private providers offering pre-payment schemes to their patients. Responses from a significant proportion of employers and employees show that PHI schemes may be abandoned once the mandatory NHI scheme is implemented. A few respondents argued that they would maintain their PHI subscriptions because of their perceptions of the quality of services likely to be provided under the NHI scheme. If successfully introduced, the NHI scheme may displace existing private health insurance and/or pre-payment schemes in Uganda. The extent to which PHI schemes are displaced depends on whether NHI is successfully implemented and the quality of services being offered under the NHI scheme.

Incidence, prevalence and mortality trends of dialysis end-stage renal disease in Taiwan from 1990 to 2001: the impact of national health insurance

Incident and prevalent (I&P) rates in dialysis end-stage renal disease (ESRD) patients in Taiwan increased rapidly following the launch of National Health Insurance (NHI) in 1995. Our aim was to explore the impact of NHI on the status and trends of ESRD epidemiology in Taiwan. This study was conducted using retrospective cohort analysis of data collected from the Taiwan national dialysis registry. From 1990 to 2001, I&P rates of ESRD patients increased 2.6 times from 126 to 331 per million populations (pmp) and 3.46 times from 382 to 1322 pmp, respectively. Increasing ESRD was seen in patients who were middle-aged, elderly and who had diabetic nephropathy as their primary renal disease. The mean age of I&P patients increased by 7.2 years and 7.1 years, respectively. All of these parameters increased markedly in 1995, the year of NHI implementation. First-year mortality decreased to 7.8 per 1000 patient-months in 1994, and then increased to 18.0 in 2001. The cumulative survival rate of the elderly subgroup (age >65) in the incident 1990-1994 cohort was greater than in the 1995-1999 cohort. These data indicated that NHI implementation significantly influenced the inflow and the mortality of ESRD patients. In addition to presenting ESRD epidemiology in Taiwan, this study demonstrated that NHI implementation stimulated the growth of treated ESRD populations. Preventive plans mounted against chronic kidney diseases will be essential to reduce the growth of ESRD patient numbers and consequent economic burdens.

DO ADULT CHILDREN MATTER?—THE EFFECTS OF NATIONAL HEALTH INSURANCE ON RETIREMENT BEHAVIOR: EVIDENCE FROM TAIWAN

This paper examines the effect of the 1995 implementation of National Health Insurance (NHI) on retirement behavior in Taiwan. The identification strategy is based on the fact that, in Taiwan, adult children offer significant insurance to elderly parents. The results suggest that NHI had significant effects on retirement among the elderly lacking an adequate traditional “safety net.” NHI raised the conditional probability that a male, private sector worker over the age of 51 would retire by more than 60%. However, men with a stronger safety net in the form of adult sons were less responsive to NHI. (JEL I18, J14, J26)

Evidence for improved control of hypertension in Taiwan: 1993–2002

This study reports the prevalence of hypertension, proportions of awareness, treatment, and control in the 2002 Taiwanese Survey on Hypertension, Hyperglycemia, and Hyperlipidemia (TwSHHH), and compared the changes of hypertension prevalence, awareness, treatment, and control in two recent nationwide surveys. TwSHHH is the second nationwide survey designed to assess the prevalence, awareness, treatment, and control of hyperglycemia, hyperlipidemia, and hypertension. The TwSHHH survey applied a multistage, stratified, and random sampling during 2002 with a total of 7566 participants. Among them, 3088 male and 3391 female participants were 19 years old and over and were selected from households throughout Taiwan. The data of Nutrition and Health Survey in Taiwan (NAHSIT), the first nationwide survey to assess disease and nutrition status during 1993-1996, was also applied to compare changes of the prevalence, awareness, treatment, and control of hypertension between the two surveys. Compared with the NAHSIT, the prevalence of hypertension on TwSHHH decreased significantly in female adults, between 1993-1996 and 2002. In both males and females of all age groups, the awareness, treatment, and control of hypertension significantly and substantially improved between NAHSIT and TwSHHH. These results also correlated in time with the implementation of National Health Insurance since 1995. The favorable changes in education and availability of care may account for improved control of hypertension and, possibly, its prevention. There was a significant improvement of hypertension awareness, treatment, and control in the TwSHHH survey compared with the NAHSIT survey in Taiwan.

Increasing the hospitalization of asthma in children not in adults – from a national survey in Taiwan 1996–2002

Prevalence of asthma has risen gradually in past 30 yr in Taiwan, but less is known about the trend of asthma hospitalization and different hospitalization patterns between children and adult groups in the Chinese population. The implementation of National Health Insurance (NHI) in Taiwan was in 1995, and it covered health care for >96% of the population. Using NHI data from 1996 to 2002, we investigated the admission rate, length of stay, cost and the readmission rate of hospitalization with primary diagnosis of asthma in this period. We also compare the difference between the children group (<18 yr old) and adult group (> or =18 yr old). The average incidence of hospitalization in the age group below 18 was 105.0 cases per 100,000 children, and was 116.7 per 100,000 population in the adult group during that period. It increased by 6.5% annually in the children group, though it was 0.1% annually in the adult group. The hospitalization days were 3.6 +/- 2.4 days in the children group, and were 8.2 +/- 8.9 days of those age > or =18 (p < 0.0001). The hospitalization cost was $288.7 +/- $292.9 and $717.5 +/- $1409.4, respectively (p < 0.0001). Autumn was the most frequent admission season in the children group, but the winter season was the most common in the adult group. The average readmission rate in this period was 20.4%. It was 13.0% in the children group, and was 22.6% in the adult group (p < 0.0001). The general hospitalization rate of asthma in the children group was lower than the adult group. It increased significantly in the children group from 1996 to 2002, but the admission cost rose prominently in the adult group during the same period. The hospitalization days, admission cost, and readmission rate were also significantly lower in the children group.

Taiwan?s High Rate of Cesarean Births: Impacts of National Health Insurance and Fetal Gender Preference

Taiwan has a high rate of cesarean section, approximately 33 percent in the past decade. This study investigates and discusses 2 possible factors that may encourage the practice, one of which is fetal gender difference and the other is Taiwan's recently implemented National Health Insurance (NHI). A logistic regression model was used with the 1989 and 1996 National Maternal and Infant Health Survey and with the 2001 to 2003 NHI Research Databases. Using survey data, we found a statistically significant 0.3 percent gender difference in parental choice for cesarean section. However, no statistically significant difference was found in the rate of cesarean section before and after NHI implementation. Taiwan's high cesarean section rate is not directly related to financial incentives under NHI, indicating that adjusting policy to lower financial incentives from NHI would have only limited effect. Likewise, focusing effort on the small gender difference is unlikely to have much impact. Effective campaigns by health authorities might be conducted to educate the general population about risks associated with cesarean section and the benefits of vaginal birth to the child, mother, and society.

Clinical characteristics and survival of trisomy 13 in a medical center in Taiwan, 1985–2004

This study investigated the survival and natural history of trisomy 13 in a series of patients, comparing the management and outcome before and after the implementation of Taiwan's National Health Insurance program (NHI). A total of 28 cases of trisomy 13 seen at Mackay Memorial Hospital, Taipei, Taiwan, from 1985 to 2004 were retrospectively reviewed. Survival and management before (12 cases) and after (16 cases) the implementation of National Health Insurance were compared, and structural defects, imaging findings, and cytogenetic results were analyzed. The cases that were diagnosed prenatally, and finally terminated, were excluded from this study. The diagnosis of trisomy 13 was based on the postnatal chromosome analysis. All patients except one with trisomy 13 translocation died in their first year because of severe malformations of the cardiovascular or central nervous system. The median survival was 9 days. After implementation of National Health Insurance, survival with trisomy 13 was significantly longer than before (P < 0.05). The three most common structural defects were abnormal auricular helices or low-set ears (89%), cryptorchidism and abnormal scrotum of male (73%) and cleft lip and/or palate (71%). Using echocardiography, the most commonly detected heart defects were patent ductus arteriosus (68%), ventricular septal defect (50%) and atrial septal defect (50%), and eight cases (36%) had complex congenital heart defects. The most common brain lesion was lenticulostriate vasculopathy (22%), followed by holoprosencephaly (17%), brain edema (13%) and subependymal cyst (13%). Early diagnosis and the survival patterns from the data collected should be used to inform parents and health-care professionals to assist in decision making. Although most patients with trisomy 13 die within the first weeks after birth, it is important to recognize that a few may survive the first year. When counseling families, the long-term survival prospects of trisomy 13 patients should be included.

Gifts, bribes and solicitions: Print media and the social construction of informal payments to doctors in Taiwan

The Taiwanese practice of patients giving informal payments to physicians to secure services is deeply rooted in social and cultural factors. This study examines the portrayal of informal payments by Taiwanese print news media over a period of 12 years—from prior to until after the implementation of national health insurance (NHI) in Taiwan in 1995. The goal of the study was to examine how the advent of NHI changed the rationale for and use of informal payments. Both before and after the introduction of NHI, Taiwanese newspapers portrayed informal payments as appropriate means to secure access to better health care. Newspaper accounts established that, although NHI reduced patients’ financial barriers to care, it did not change deeply held cultural beliefs that good care depended on the development of a reciprocal sense of obligation between patients and physicians. Physicians may have also encouraged the ongoing use of informal payments to make up revenue lost when NHI standardized fees and limited income from dispensing medications. In 2002, seven years after the implementation of NHI, the use of informal payments, though illegal, was still being justified in the print media through allusions to its role in traditional Taiwanese culture.

Clinical characteristics and survival of trisomy 18 in a medical center in Taipei, 1988–2004

Trisomy 18 is the second most common autosomal trisomy in newborns. The birth prevalence of this disorder is approximately 1 in 3,000 to 1 in 8,000, and the life span of the majority of patients is less than 1 year. As information regarding outcome in trisomy 18 is rather fragmentary in the literature, this study is aimed at investigating the survival and natural history of trisomy 18. We also evaluated the survival age and management of trisomy 18 in two different periods, before and after the implementation of National Health Insurance (NHI) program. Thirty-nine cases of trisomy 18 were collected in Mackay Memorial Hospital in a 17-year period, from 1988 to 2004. Delivery data, survival age, management before and after the implementation of NHI program, structural defects, image findings and cytogenetic results were analyzed by medical and nurse's records. The diagnosis of trisomy 18 was based on the prenatal amniocentesis or postnatal chromosome analysis. Three patients had trisomy 18 mosaicism. Since cardiovascular and central nervous systems are the most common organ systems involved in this disorder, 31 patients received brain ultrasonography and heart ultrasonography for evaluation of their multiple anomalies after admission. All patients except one died in their first year due to severe malformations of the cardiovascular or central nervous systems. The median survival age was 6 days. We found a longer survival with female patients than with male patients (P < 0.05). Implementation of NHI program in the more recent decade of this study period was associated with longer survival of trisomy 18 (P < 0.05). The three most common structural defects were clenched hands (95%), rocker bottom feet (90%), and low set or malformed ears (90%). Low birth weight was present in 90%. By cardiac ultrasonography, the top four heart defects were ventricular septal defect (94%), patent ductus arteriosus (77%) and atrial septal defect (68%). However, ten cases (32%) had complex congenital heart defects. By brain ultrasonography, the most common brain lesion was cerebellar hypoplasia (32%), followed by brain edema (29%), enlarged cisterna magna (26%) and choroid plexus cysts (19%). Although most patients with trisomy 18 die within the first few weeks after birth, it is important to recognize that a small but notable percentage of these patients will survive the first year. When prenatal or postnatal decisions need to be made, the possibility of long-term survival should be included in any discussion to enable families to make the most appropriate decision.

Household out-of-pocket medical expenditures and national health insurance in Taiwan: income and regional inequality

BackgroundUnequal geographical distribution of medical care resources and insufficient healthcare coverage have been two long-standing problems with Taiwan's public health system. The implementation of National Health Insurance (NHI) attempted to mitigate the inequality in health care use. This study examines the degree to which Taiwan's National Health Insurance (NHI) has reduced out-of-pocket medical expenditures in households in different regions and varying levels of income.MethodsData used in this study were drawn from the 1994 and 1996 Surveys of Family Income and Expenditure. We pooled the data from 1994 and 1996 and included a year dummy variable (NHI), equal to 1 if the household data came from 1996 in order to assess the impact of NHI on household out-of-pocket medical care expenditures shortly after its implementation in 1995.ResultsAn individual who was older, female, married, unemployed, better educated, richer, head of a larger family household, or living in the central and eastern areas was more likely to have greater household out-of-pocket medical expenditures. NHI was found to have effectively reduced household out-of-pocket medical expenditures by 23.08%, particularly for more affluent households. With the implementation of NHI, lower and middle income quintiles had smaller decreases in out-of-pocket medical expenditure. NHI was also found to have reduced household out-of-pocket medical expenditures more for households in eastern Taiwan.ConclusionAlthough NHI was established to create free medical care for all, further effort is needed to reduce the medical costs for certain disadvantaged groups, particularly the poor and aborigines, if equality is to be achieved.

Characteristics of primary osteomyelitis among children in a medical center in Taipei, 1984-2002.

The presentation and sequelae of osteomyelitis are variable. This study evaluated the clinical manifestations and outcome of osteomyelitis in children in different age groups, and in different periods before and after the implementation of National Health Insurance (NHI). The records of pediatric patients with osteomyelitis treated at a medical center in Taipei from 1984 to 2002 were reviewed. Clinical features, pathogens, laboratory and imaging findings, treatment, and outcome were analyzed. The patients were stratified into 3 groups based on age: infants (< or = 3 months of age), young children (between 4 months and 5 years), and older children and adolescents (> 5 years). Based on the date of implementation of the NHI program, the study period was divided into 2 stages: prior to implementation, from January 1984 to February 1995; and after implementation, from March 1995 to December 2002. The records of 209 patients were reviewed, including 45 infants, 77 young children, and 87 older children. The most common presenting findings were local tenderness (79%), local swelling (72%), and fever (57%). The lower limbs were the most commonly involved sites (65%). Staphylococcus aureus (34%), Mycobacterium tuberculosis (10%), Salmonella species (7%), and Pseudomonas aeruginosa (6%) were the most frequently isolated pathogens. At the time of diagnosis, abnormalities were found on radiographs in 83% of patients and on radionuclide bone scans in 86%. Surgical intervention with local debridement and curettage was performed in 102 patients (49%). Sixty five patients (31%) developed complications, including specific bony sequelae in 26 (12%). Sepsis and septic arthritis were more common in infants (p < 0.01). A history of trauma, protracted course of osteomyelitis, and surgical intervention were more common in older children and adolescents (p < 0.01). After the implementation of NHI, a larger proportion of patients had negative cultures (p < 0.01), and the mean duration of antibiotic therapy was shorter (p = 0.01). The clinical characteristics of osteomyelitis associated with sepsis or septic arthritis, chronic changes, and the need for surgery may differ depending on the age of the child. S. aureus, M. tuberculosis, and salmonellae were the most common pathogens in this Taiwanese series. Implementation of NHI in the more recent decade of the study period was associated with a shorter duration of intravenous antibiotic administration.
