Epidemiology of Behcet's Disease in Taiwan: A Population-Based Study

PURPOSE

To study the incidence and epidemiology of Behcet's disease in Taiwan.

METHODS

This retrospective cohort study was conducted using the nationwide reimbursement database in Taiwan. One million registered beneficiaries of the Taiwan National Health Insurance system in 2000 were randomly selected. All medical claims of these persons were collected. The definition of having Behcet's disease was based on diagnostic codes. Persons who had incomplete registry data or diagnoses prior to 2001 were excluded. Annual incidence between 2001 and 2011 was calculated and risk factors for incidence were explored using the Cox proportional regression model. Characteristics of patients with Behcet's disease with and without uveitis were compared.

RESULTS

A total of 236 newly diagnosed patients with Behcet's disease were found between 2001 and 2011. The average incidence was 2.40 cases per 100,000 person-years (ranging from 1.29 to 3.53). Female patients and those aged between 40 and 65 years were at the highest risk of Behcet's disease. Only 18.2% of the patients had also suffered from uveitis. The subspecialties of doctors making initial diagnoses and the number of prescribed immunomodulatory agents differed significantly between the patients with and without uveitis (p < 0.001 and <0.05, respectively).

CONCLUSION

Incidence of Behcet's disease was not high in Taiwan and relatively few of the patients developed uveitis. Patients of working age or who were female were more likely to have Behcet's disease. However, age of onset and clinical severity differed between patients with and without uveitis.

Persistence of topical glaucoma medication: a nationwide population-based cohort study in Taiwan

IMPORTANCE

Medication persistence is an important factor for treatment effect in patients with glaucoma. Evaluating risk factors for refill discontinuation might be helpful for improving persistence and preventing blindness in patients with glaucoma.

OBJECTIVES

To estimate the persistence rate with topical glaucoma medication 2 years after diagnosis and evaluate risk factors for nonpersistence among patients in Taiwan with open-angle glaucoma and ocular hypertension.

DESIGN, SETTING, AND PARTICIPANTS

A retrospective population-based study using claims data from the National Health Insurance Research Database. One million patients were randomly selected from the registered beneficiaries of the National Health Insurance Research Database in 2000. All patients with newly diagnosed open-angle glaucoma and ocular hypertension were included and followed up until December 31, 2008. Patients were included in the analysis only if they had follow-up data for more than 2 years after diagnosis.

MAIN OUTCOMES AND MEASURES

Nonpersistence was defined as the patient not refilling any topical glaucoma medication for more than 90 days. Patient characteristics, prescription-related clinical factors, and physician and hospital characteristics were identified and considered in the analysis. The rate of persistence was estimated and risk factors for nonpersistence were investigated using Cox proportional regression models.

RESULTS

A total of 3134 patients were identified and observed in the study. After a 2-year follow-up, 759 patients (24.2%) persisted with their glaucoma medications. Multivariate analysis showed that patients' living or working areas (P < .001), number of glaucoma medications (P < .001), prescription of pilocarpine hydrochloride (adjusted ratio of persistence = 0.72; 95% CI, 0.59-0.88) or prostaglandin analogs (adjusted ratio of persistence = 2.04; 95% CI, 1.82-2.33), the year in which glaucoma diagnosis was made (adjusted ratios of persistence for patients whose condition was diagnosed after 2004 = 1.18; 95% CI, 1.09-1.27), sex of the main physicians (adjusted ratios of persistence for male ophthalmologists = 0.82; 95% CI, 0.74-0.90), treatment in hospitals (P < .001), and continuity of care index (P < .001) were associated with patients' persistence with glaucoma medications.

CONCLUSIONS AND RELEVANCE

The rate of persistence for glaucoma medications is low in Taiwan, although health care costs, including the cost of medication, are mostly covered by the nationwide health insurance system. This study suggests that factors other than cost, such as physician-patient relationship and patient education, may play an important role in the persistence of topical glaucoma medication.

Models of long-term care use among older people with disabilities in Taiwan: institutional care, community care, live-in migrant care and family care

The four main models of long-term care (LTC) for older people in Taiwan are institutional care, community and home-based care, live-in migrant care and family care. This study aims to examine the factors associated with the four above-mentioned LTC models, using the Andersen model as its framework for analysis. Data were from the 2005 National Taiwanese Health Interview Survey (n = 30,680), and in this study, 592 over 65-year-old persons who require personal care in daily life were included. The findings showed that the majority of older people with care needs lived with family and were cared only by their family. The second largest group was those older people who were cared by migrant care workers, and the third group used institutional care. Only a very small proportion used community/home-based care services. If older people had intensive care needs, they either hired migrant care workers or used institutional care, depending on social and economic backgrounds. Multinomial logistic regression results showed that the way how disabled older people use different LTC models was affected by three components of the Andersen model: their needs (level of ADL and IADL), predisposing factors (age, education) and enabling factors (family networks). Results suggest that there is a need for LTC policies in Taiwan to provide more available and accessible community/home-based care services, particularly for older people with intensive care needs, in order to support their 'ageing in place' and to decrease the use of migrant care workers.

Menopause experiences and attitudes in women with intellectual disability and in their family carers

BACKGROUND

Little is known about how middle-aged and older women with intellectual disability (ID) cope with life transitions such as perimenopause and postmenopause.

METHOD

A mixed methods approach was employed to explore the attitudes toward and experiences of menopause among women with ID and their family carers in one city in Taiwan.

RESULTS

A survey found that how the carers perceived the level of menopausal symptoms in their female family members with ID was affected by their attitudes toward menopause; and carer age and education were significant factors associated with carer menopausal attitudes. The results of in-depth interviews indicated the carers' gender, age, kinships with the women with ID, and the carers' own menopausal experiences were related to how the carers felt about the menopausal transition of the women with ID.

CONCLUSIONS

Both quantitative and qualitative findings show that little attention has been paid to either the menopausal transition experiences or the wellbeing of women with ID.

Difficulties of care-work reconciliation: employed and nonemployed mothers of children with intellectual disability

BACKGROUND

Whether employed and nonemployed mothers of children with intellectual disability (ID) have different experiences with reconciliation between care and work has rarely been explored.

METHOD

A survey was conducted in a county in Taiwan and 487 mothers aged younger than 65 and having a child with ID were interviewed face to face at their homes to explore whether there are different factors related to the reconciliation between care and work among employed and nonemployed mothers.

RESULTS

Except for the common ground of mothers' health and care demands, logistic regression revealed work flexibility and care support were important for employed mothers. In contrast, the success of reconciliation for nonemployed mothers was determined by their individual characteristics (i.e., age, marital status, family income).

CONCLUSIONS

Reconciliation policies for mothers with different employment statuses need to use different strategies.

Pulmonary tuberculosis increases the risk of lung cancer: a population-based cohort study

BACKGROUND

The possible effect of pulmonary tuberculosis (TB) on subsequent lung cancer development has been suspected, but the evidence remains inconsistent. The purpose of this study was to perform a nationwide population-based cohort study to investigate the risk of lung cancer after pulmonary TB infection.

METHODS

This nationwide population-based cohort study was based on data obtained from the Taiwan National Health Insurance Database. In total, 5657 TB patients and 23,984 controls matched for age and sex were recruited for the study from 1997 to 2008.

RESULTS

The incidence rate of lung cancer (269 of 100,000 person-years) was significantly higher in the pulmonary TB patients than that in controls (153 of 100,000 person-years) (incidence rate ratio [IRR], 1.76; 95% confidence interval [CI], 1.33-2.32; P < .001). Compared with the controls, the IRRs of lung cancer in the TB cohort were 1.98 at 2 to 4 years, 1.42 at 5 to 7 years, and 1.59 at 8 to 12 years after TB infections. The multivariate Cox proportional hazards model revealed pulmonary TB infections (hazard ratio [HR], 1.64; 95% CI, 1.24-2.15; P < .001) and chronic obstructive pulmonary disease (HR, 1.09; 95% CI, 1.03-1.14; P = .002) to be independent risk factors for lung cancer.

CONCLUSIONS

Pulmonary infection with TB is associated with an increased risk of lung cancer.

Caring, employment, and quality of life: comparison of employed and nonemployed mothers of adults with intellectual disability

The effects of caregiving on mothers of adults with intellectual disability was examined by determining whether there are differences in quality of life and related factors between mothers with different employment status. Study participants were 302 working-age mothers who had adult children with intellectual disability based on the 2008 census survey on intellectual disability carried out in Hsinchu, City, Taiwan. Results revealed that nonemployed mothers are more likely to have a lower level of health status, including the WHOQOL Physical Health domain, than are mothers employed fulltime. Multiple regression analysis showed that mothers' quality of life was significantly determined by the availability of a person with whom they could share care work, family income, social support, and employment status.

Effect of perceived stigmatization on the quality of life among ageing female family carers: a comparison of carers of adults with intellectual disability and carers of adults with mental illness

BACKGROUND

Little account has been taken of quality of life (QoL) among family carers of adults with an intellectual disability (ID) and family carers of adults with a mental illness (MI), particularly the female ageing carers' perceived stigma. We explore whether there are differences in the significant predictors of female ageing family carers' QoL between family carers of adults with ID and family carers of adults with MI and aim to examine the effect of these differences in stigma on carer QoL between the two groups.

METHODS

A structural survey interview was administered to 350 female family carers supporting persons with ID and 66 female carers supporting persons with MI; the carers were aged 55 years and older, and the interviews were carried between July 2006 and April 2007 at the carers' homes in a county in Taiwan. The survey package contained standardised scales to measure the carer's stigma, social support, QoL and health as well as adult and carer socio-demographic data.

RESULTS

The results highlight that in both groups the ageing female family carers' health and social support were strongly associated with the level of their QoL even though there was also a strong effect of carers' perceived stigma on their QoL. Contrary to previous findings, ageing female family carers of adults with MI had a higher level of QoL compared with the carers of adults with ID. Hierarchical regressions show a stronger effect of perceived stigma on the carer QoL among the family carers of adults with MI than among the carers of adults with ID.

CONCLUSIONS

This study suggests that attempts to improve these female older family carers' health and social support must include their lifelong unmet needs in terms of how to cope with the perceived stigma associated with their position.

Prevalence and severity of menstrual symptoms among institutionalised women with an intellectual disability

BACKGROUND

Perimenstrual syndrome (PMS) among women with an intellectual disability (ID) has not been investigated in Taiwan. This study explores the prevalence/severity of PMS experienced by women with ID who are institutionalised.

METHOD

Ninety two female residents aged 15 to 54 at six public institutions completed a structured interview between June and November 2006, together with the Moos Menstrual Distress Questionnaire (MMDQ).

RESULTS

Strong significant differences were detected between the participants' physical, emotional, behavioural, and psychological changes during the perimenstrual and remainder phases in all domains other than Arousal. Cramps, hot flushes, affection, orderliness, excitement, and bursts of energy/activity were most prevalent during the perimenstruum (>50%). The participants' unique characteristics and cultural context were associated with the various domains of the PMS.

CONCLUSIONS

Special attention should be paid in future to ascertain whether these experiences and perceptions of PMS are common among all women with ID.

Respite care as a community care service: factors associated with the effects on family carers of adults with intellectual disability in Taiwan

BACKGROUND

This study examines the effects and associated factors of respite care, which was legislated as a community service for adults with an intellectual disability (ID) in Taiwan in 1997.

METHOD

A total of 116 family carers who live with an adult with ID and have utilised the respite care program were surveyed using standardised measures.

RESULTS

The results suggest that the most notable effects of respite care include improvement in the carers' social support and life satisfaction, and relief of psychological stress and overall burden of care. The factors associated with these effects include the way the participants have used the respite care and the users' individual characteristics.

CONCLUSIONS

How families used the respite care, whether the carers practised a religion, and where the families resided, were the most significant factors in determining the effectiveness of the respite. Suggestions are made for making access to information about the program more widely available, and for extending the availability and duration of the service.
