The Impact of Falls and Fear of Falling on Health-Related Quality of Life in Taiwanese Elderly

This study aimed to investigate the relationship among falls, fear of falling (FOF), and health-related quality of life (HRQOL) in elderly people living in the community. The study was a community-based surveillance with residents aged 65 or over in Taipei, Taiwan. Data were collected in face-to-face interviews. Of the 4,056 participants, the prevalence of falls was 13.8% and the prevalence of FOF among women (62.6%) was significantly higher than that among men (46.2%). Adjusted by covariate factors, fear of falling was identified as a major factor related to HRQOL in the elderly and should be emphasized to assist the improvement of HRQOL in geriatrics.

Incidence, risk factors and consequences of falling injuries among the community-dwelling elderly in Shihpai, Taiwan

Background and aims: Falls causing injuries among older people and the consequences of those injuries are of increasing concern to public health practitioners. The aims of this study were to determine the incidence, characteristics and risk factors of fall injuries among the community-dwelling elderly in Shihpai, Taiwan; the impact on quality of life and health service utilization was also comprehensively studied. Methods: 1361 community-dwelling elderly who had been enrolled in the Shihpai eye study (1999–2000) were included. Subjects were interviewed and examined by trained interviewers, and data such as demographics, medical conditions, blood pressure, ophthalmic examination, fall history and quality of life (SF-36) were collected. Chi-square tests, analyses of covariance and multiple logistic regressions were performed as the main statistical methods. Results: The mean age of the participants was 72.2 (range, 65–91) years old. 16.3% of the elderly persons interviewed had experienced at least one fall; among those, up to 50% had suffered mild injuries, and the incidence of remarkable injury was 27.6%. There were no significant differences in the location or time of falling, but there were different risk factors and consequences in injury severity. Fallers with remarkable injuries had a higher incidence of hospitalization and a greater fear of falling. No statistically significant decline in quality of life with increasing severity of falling injury was identified after a 12-month follow-up period. Conclusions: Gender, visual impairment and orthostatic hypotension were identified as the major risk factors of fall injuries in the elderly. These factors should be emphasized in order to reduce fall injuries in geriatrics.

Assessment of Changes in Knowledge and Stigmatization Following Tuberculosis Training Workshops in Taiwan

BACKGROUND/PURPOSE There is little understanding of the depth of knowledge of health workers involved in tuberculosis (TB) control programs, and even less is known about health workers attaching stigma to TB patients. This study surveyed health workers enrolled in TB training workshops prior to the execution of the directly observed treatment, short course (DOTS) program. METHODS All participants attended the training course and completed structured questionnaires before (pre-test) and after training (post-test). The questionnaires were collected immediately following completion and the scores were analyzed. RESULTS Pair comparison of knowledge scores revealed that all participants made statistically significant improvements in level of TB knowledge, except those who had a history of TB (p = 0.331). Pair comparison of stigmatization scores revealed a reduction in stigmatization, with the DOTS workers attaching less stigma to TB patients. After training, caregivers, including women (p = 0.012), public health workers (p = 0.028), 40-49-year-old subjects (p = 0.035), those with an education of < 12 years (p = 0.024), those who had been a volunteer (p = 0.018), and those who had a history of TB and those who did not (p = 0.034, p = 0.036), were significantly less likely to stigmatize patients. TB knowledge was not found to be significantly correlated with stigmatization (pre-test, p = 0.298; post-test, p = 0.821). CONCLUSION Training workshops in TB control were effective for promotion of knowledge and elimination of stigmatization in first-line caregivers. DOTS workers attached less stigma to TB patients than public health workers, and older workers who had been volunteers attached the least stigma.

Epidemiology of Hospitalized Traumatic Pelvic Fractures and Their Combined Injuries in Taiwan: 2000–2011 National Health Insurance Data Surveillance

Background. From the viewpoint of prehospital emergency medicine, a greater proportion of pelvic fractures not of a life-threatening status but combined with other injuries need more comprehensive recognition. Methods. A 12-year nationwide health database of inpatients was reviewed. All cases diagnosed as pelvic fractures were enrolled. The associated injuries classified into 20 categories were further analyzed. Results. During 2000–2011, the hospitalized incidence of pelvic fractures in Taiwan ranged from 17.17 to 19.42 per 100,000, and an increasing trend with age was observed. The mean case-fatality rate was 1.6% for females and 2.1% for males; male patients with pelvic fractures had a significantly higher risk of death than female patients after adjusting for other covariates. 74.2% of these cases were combined with other injuries. The most common associated injuries in an identified body region were other orthopedic fractures of the lower limbs (21.50%), spine/trunk (20.97%), or upper limbs (18.18%), followed by significant head injuries (17.59%), intra-abdominal injuries (11.00%), and thoracic injuries (7.20%). Conclusion. The incidence of hospitalized pelvic fractures in Taiwan was low and the case-fatality rate was lower than those of other countries. Concurrently, coexistence of major combined injuries with pelvic fractures was easily treated at medical centers.

Epidemiology of Orthopedic Fractures and Other Injuries among Inpatients Admitted due to Traffic Accidents: A 10-Year Nationwide Survey in Taiwan

To investigate the major injury patterns associated with traffic accidents and evaluate the risk factors of the main injury, a survey of Taiwans national insurance admission data between 2002 and 2011 was performed. The incidence of traffic-accidents-related hospitalization was between 9.17% and 11.54% and the average mortality rate of the inpatients admitted due to traffic accidents was 0.68%. Of all inpatients due to road traffic accidents in Taiwan, orthopedic fractures were the most common injuries that accounted for 29.36% of them. There were a total of 391,197 cases of three orthopedic fracture groups that were divided into (1) fracture of upper limb, (2) fracture of lower limb, and (3) fracture of spine and trunk. An increase in national medical cost used for inpatients with orthopedic fractures was noted and ranged from US

86 million annually. These orthopedic fracture patterns were frequently associated with other injuries especially head injuries (ranged from 14% to 26%). A significant relation to male gender, older age, low income, and admission to high-level hospital to the observed fracture patterns was observed.

Emergency visits among end-of-life cancer patients in Taiwan: a nationwide population-based study

Background The burden of chronic kidney disease (CKD) is a growing concern worldwide. The prevalence of hemodialysis in Taiwan is the highest in the world, and this may increase the prevalence of orthopedic fractures. The aim of this study was to explore the incidences of various orthopedic injuries and the related risk factors. Methods A nationwide prospective study based on the Taiwan National Health Insurance dataset was conducted during 2004–2008. A total of 82,491 CKD patients were selected as the fixed cohort population. The International Classification of Diseases 9-CM diagnosis codes and treatment codes were identified as the inclusion criteria for orthopedic injury. Results A total of 82,491 Taiwanese people with CKD were identified in 2004, and 4915 orthopedic injuries occurred during the 5-year follow-up period. The cumulative incidences of orthopedic injuries were 42.56‰ for lower limb fractures, and 12.93‰, 3.27‰, and 1.64‰ for upper limb fractures, vertebrae fractures, and joint dislocations, respectively. All three types of orthopedic fractures were more common in the oldest age stratum (≥65 years old). In the CKD patients, the risk ratio of osteoporosis was 3.47 (95% confidence interval, 3.10–3.89) for all orthopedic injuries. Patients of advanced age, the female gender, and those with high comorbidity were also at significant risk of sustaining orthopedic fractures. Conclusion The results from this Taiwanese CKD cohort support the strong influence of aging and osteoporosis on all kinds of orthopedic injuries. The postponing of osteoporosis may need to be taken into consideration for the prevention of orthopedic injury among CKD patients undergoing hemodialysis.

The incidence, risk factors and consequences of falling injury among the community elderly in Shihpai, Taiwan

BACKGROUND/PURPOSE Taiwan saw an increase in immigration during the last decade. This retrospective study investigated whether immigrant status confers a protective effect on birth outcomes and whether this effect varies across racial/ethnic subgroups in Hsin-Chu County, Taiwan. METHODS A total of 30,770 singleton birth certificates from January 1, 2002 to July 31, 2007 were analyzed using ANOVA and logistic regression. Outcomes included low birth weight (LBW, < 2500 g), high birth weight (HBW, > 4000 g), preterm birth (< 37 weeks) and stillbirth. Covariates included maternal age, year of delivery, mode of delivery, medical care institution, infant sex and congenital birth defects. Five models were designed for various analyses. The reference categories included non-immigrant, non-aboriginal Taiwanese and non-Chinese-speaking immigrants. RESULTS Preterm rate ranged from 6.3% among mainland Chinese to 13.5% among aboriginal Taiwanese. LBW rate ranged from 4.3% among mainland Chinese to 17.3% among aboriginal Taiwanese. HBW rate ranged from 1.2% among aboriginal Taiwanese to 3.4% among mainland Chinese. Stillbirth rate ranged from 0.2% among Indonesians to 0.7% among aboriginal Taiwanese. Adjusted odds ratio (OR) was lower among mainland Chinese (preterm OR, 0.77; LBW OR, 0.62) but higher among aboriginal Taiwanese (preterm OR, 1.79; LBW OR, 2.68; stillbirth OR, 2.92). HBW rate was significantly higher (OR, 1.84) among mainland Chinese. Chinese-speaking immigrants showed significant differences in LBW (OR, 0.57) and HBW (OR, 1.62) compared with non-Chinese-speaking immigrants. CONCLUSION An epidemiologic paradox and heterogeneity of birth outcomes were observed among immigrants in this study. However, aboriginal Taiwanese constituted the subgroup with the highest risk. Further research is needed to identify the determinants of birth outcomes.

Effect of socioeconomic inequalities on cholecystectomy outcomes: a 10-year population-based analysis

BackgroundAn increased number of emergency visits at the end of life may indicate poor-quality cancer care. The study aimed to investigate the prevalence and utilization of emergency visits and to explore the reasons for emergency department (ED) visits among cancer patients at the end of life.MethodsA retrospective cohort study was performed by tracking one year of ambulatory medical service records before death. Data were collected from the cancer dataset of Taiwan’s National Health Insurance Research Database (NHIRD).ResultsA total of 32,772 (19.2%) patients with malignant cancer visited EDs, and 23,883 patients died during the study period. Of these, the prevalence of emergency visits in the mortality group was 81.5%, and their ED utilization was significantly increased monthly to the end of life. The most frequent types of cancer were digestive and peritoneum cancers (34.8%), followed by breast cancer (17.7%) and head and neck cancers (13.3%). Older patients, males, and those diagnosed with metastases, respiratory or digestive cancer were more likely to use ED services at the end of life. Use of an ED service in the nearest community hospital to replace medical centers for dying cancer patients would be more acceptable in emergency situations.ConclusionsOur study provided population-based evidence related to ED utilization. An understanding of the reasons for such visits could be useful in preventing overuse of ED visits to improve the quality of end-of-life care.
