A Randomized Clinical Trial on Therapeutic Effects of Myrtus communis L. Cream on Chronic Skin Lesions and Quality of Life of Sulfur Mustard-exposed Veterans

Abstract: Sulfur mustard is one of the chemical warfare agent. It rapidly reacts with the cutaneous tissues and other tissues, leading to various devastating long-term effects on human health. Mustard-exposed veterans suffer from its chronic skin problems, including itching, burning sensation, and eczema. We aimed to evaluate the protective effects of Myrtus communis L. (myrtle) on chronic skin lesions and quality of life of sulfur mustard-exposed veterans. In this randomized, double-blind clinical trial, 60 sulfur mustard-exposed patients were evaluated. Thirty patients received myrtle essence 5% cream (case group) and 30 patients received Eucerin cream (placebo group) twice in a day for one month. Then, We assessed the chronic skin problems and itching-related parameters (such as the itching time, severity, distribution, frequency, and calculated itching score), duration of sleep, number of waking up at night, and quality of life in the both groups. Our analysis of data revealed that application of myrtle cream effectively decreased skin problems including; itching and burning sensation. Additionally, myrtle markedly decreased skin lesion symptoms such as excoriation in the case group as compared with before treatment. Noticeably, myrtle cream significantly improved quality of life of the patients in the case group. The present study provides more in-depth information regarding the protective role of myrtle on the sulfur mustard-induces skin complication. Also, myrtle effectively improved quality of life of the sulfur mustard-exposed veterans.

Nursing Professionals within the Intergenerational Context during the 20th and 21st Centuries: an Integrative Review / Los profesionales de enfermería en el contexto intergeneracional durante los siglos XX y XXI: una revisión integradora / Profissionais de enfermagem no contexto intergeracional durante os séculos XX e XXI: uma revisão integrativa

Objective. To describe the generational differences and similarities existing among nursing professionals of the 20th and 21st centuries and how these have influenced on the evolution of the profession. Methods. Integrative review according to the methodology by Whittemore and Knafl. The key words used for the search were: nurses, intergenerational relations, Veterans, Baby Boom, X generation, and Millennials. Results. The electronic search process yielded 10 documents (eight articles and two theses), all within the Anglo-Saxon environment (4 in Canada, 5 in the United States, and 1 in Australia). The documents recovered determined three principal themes: the intergenerational nursing workforce (n = 7), recruiting and retention within an intergenerational workforce (n = 2), and tutoring within an intergenerational nursing workforce (n = 1). The four generations of nursing professionals (X, Y, Baby Boomers, and Veterans) have different aptitudes, social and cultural setting, that coexist within the same work staff. Conclusion. This study establishes the legitimacy of the intergenerational differences as an important variable of social categorization. The findings have the potential to improve generational comprehension and promote a more cohesive culture in clinical practice settings, besides conserving the legacy of the four generations of nursing professionals contributing to outline the identity of the nurses through the conservation of social, cultural, and professional experiences.

Mantle cell lymphoma relapsed after autologous stem cell transplantation: a single-center experience

BACKGROUND: Autologous stem cell transplantation (autoSCT) can extend remission of mantle cell lymphoma (MCL), but the management of subsequent relapse is challenging.METHODS: We examined consecutive patients with MCL who underwent autoSCT at Veterans Affairs Puget Sound Health Care System between 2009 and 2017 (N=37).RESULTS: Ten patients experienced disease progression after autoSCT and were included in this analysis. Median progression free survival after autoSCT was 1.8 years (range, 0.3–7.1) and median overall survival after progression was only 0.7 years (range, 0.1 to not reached). The 3 patients who survived more than 1 year after progression were treated with ibrutinib.CONCLUSION: Our findings suggest that ibrutinib can achieve relatively prolonged control of MCL progressing after autoSCT.

TpTe and TpTe/QT: novel markers to predict sudden cardiac death in ESRD? / TpTe e TpTe/QT: novos marcadores para prever morte súbita cardíaca na DRT?

ABSTRACT Introduction: Reliable markers to predict sudden cardiac death (SCD) in patients with end stage renal disease (ESRD) remain elusive, but echocardiogram (ECG) parameters may help stratify patients. Given their roles as markers for myocardial dispersion especially in high risk populations such as those with Brugada syndrome, we hypothesized that the Tpeak to Tend (TpTe) interval and TpTe/QT are independent risk factors for SCD in ESRD. Methods: Retrospective chart review was conducted on a cohort of patients with ESRD starting hemodialysis. Patients were US veterans who utilized the Veterans Affairs medical centers for health care. Average age of all participants was 66 years and the majority were males, consistent with a US veteran population. ECGs that were performed within 18 months of dialysis initiation were manually evaluated for TpTe and TpTe/QT. The primary outcomes were SCD and all-cause mortality, and these were assessed up to 5 years following dialysis initiation. Results: After exclusion criteria, 205 patients were identified, of whom 94 had a prolonged TpTe, and 61 had a prolonged TpTe/QT interval (not mutually exclusive). Overall mortality was 70.2% at 5 years and SCD was 15.2%. No significant difference was observed in the primary outcomes when examining TpTe (SCD: prolonged 16.0% vs. normal 14.4%, p=0.73; all-cause mortality: prolonged 55.3% vs. normal 47.7%, p=0.43). Likewise, no significant difference was found for TpTe/QT (SCD: prolonged 15.4% vs. normal 15.0%, p=0.51; all-cause mortality: prolonged 80.7% vs. normal 66.7%, p=0.39). Conclusions: In ESRD patients on hemodialysis, prolonged TpTe or TpTe/QT was not associated with a significant increase in SCD or all-cause mortality.

RESUMO Introdução: Marcadores confiáveis para predizer morte súbita cardíaca (MSC) em pacientes com doença renal terminal (DRT) permanecem elusivos, mas os parâmetros do ecocardiograma (ECG) podem ajudar a estratificar os pacientes. Devido a seus papéis como marcadores para a dispersão miocárdica, especialmente em populações de alto risco, como aquelas com síndrome de Brugada, nós hipotetizamos que o intervalo pico da onda T ao final da onda T (TpTe) e TpTe/QT são fatores de risco independentes para MSC na DRT. Métodos: Revisão retrospectiva do prontuário foi realizada em uma coorte de pacientes com DRT iniciando a hemodiálise. Os pacientes eram veteranos de guerra americanos que utilizavam os centros médicos do Veterans Affairs para atendimento médico. A idade média de todos os participantes foi de 66 anos e a maioria era do sexo masculino, consistente com uma população veterana dos EUA. ECGs que foram realizados dentro de 18 meses após o início da diálise, e foram avaliados manualmente para TpTe e TpTe/QT. Os desfechos primários foram MSC e mortalidade por todas as causas, e estes foram avaliados até 5 anos após o início da diálise. Resultados: Após o critério de exclusão, foram identificados 205 pacientes, dos quais 94 com TpTe prolongado e 61 com intervalo TpTe/QT prolongado (não mutuamente exclusivo). A mortalidade geral foi de 70,2% em 5 anos e a MSC foi de 15,2%. Nenhuma diferença significativa foi observada nos desfechos primários ao se avaliar o TpTe (MSC: prolongado 16,0% versus normal 14,4%, p = 0,73; mortalidade por todas as causas: prolongado 55,3% vs. normal 47,7%, p = 0,43). Da mesma forma, nenhuma diferença significativa foi encontrada para TpTe/QT (MSC: prolongado 15,4% vs. normal 15,0%, p = 0,51; mortalidade por todas as causas: prolongado 80,7% vs. normal 66,7%, p = 0,39). Conclusões: Em pacientes com insuficiência renal terminal em hemodiálise, TpTe ou TpTe/QT prolongados não foram associados a um aumento significativo da morte súbita ou mortalidade por todas as causas.

Famous veteran traditional Chinese medicine doctors' medication rules in treating spermatorrhea / 中国中药杂志

To explore famous veteran traditional Chinese medicine( TCM) doctors' medication rules in treating spermatorrhea based on the medical cases about spermatorrhea collected from Hundred TCM Clinical Doctors of Hundred Years in China and Proven Cases and National Medical Master Test Case. Researchers extracted such data as medicinal and therapies from these cases according to the inclusion and exclusion criteria. Then,Excle 2010,SPSS Clementine 12. 0 and SPSS 22. 0 were adopted respectively for frequency analysis,association rules analysis,cluster analysis and factor analysis. Cluster analysis was carried out by Ochiai algorithm of binary variable data,one of the systematic clustering methods. And principal component analysis was used for factor analysis. Finally,27 medical cases and 41 prescriptions were included in total. The frequency analysis showed that the most common therapy was the astringent therapy( n = 28),which was followed by the tonifying method,tranquilizing method,heat-clearing method,damp-dispelling method and Qiregulating method. The top three kinds of high-frequency traditional Chinese medicines were Poria,Ostreae Concha and Dioscoreae Rhizoma. The association rules analysis found out 11 association rules of medicine pairs,23 association rules of medicine combinations of the three kinds of herbs and 6 association rules of medicine combinations of five kinds of herbs. Among them,the representatives were Rubi Fructus→Fossilia Ossis Mastodi,Rehmanniae Radix Praeparata + Corni Fructus→Dioscoreae Rhizoma,and Pinelliae Rhizoma→Citri Reticulatae Pericarpium,which showed the therapeutic characteristics of astringing,tonifying the kidney and replenishing essence,fortifying the spleen and dispelling dampness. Moreover,7 medicine groups with relevance were extracted from the tree map generated by cluster analysis,including " Phellodendri Chinensis Cortex and Anemarrhenae Rhizoma" and " Angelicae Sinensis Radix,Rehmanniae Radix,Bupleuri Radix and Glycyrrhizae Radix et Rhizoma",which demonstrated the effects of nourishing Yin and purging fire,tonifying and soothing the liver. Besides,totally 12 common factors were obtained according to factor analysis,including 14 drug combinations,like " Amomi Fructus,Anemarrhenae Rhizoma and Phellodendri Chinensis Cortex" and " Nelumbinis Stamen,Moutan Cortex,Poria and Scrophulariae Radix",which indicated the compatibility characteristics of tonifying the spleen and purging fire,dispelling dampness and clearing heat. In conclusion,data mining techniques( including frequency analysis,association rules analysis,cluster analysis and factor analysis) were used to comprehensively analyze the famous veteran TCM doctors' medication rules in treating spermatorrhea,which was helpful for guiding the clinical practice of treating spermatorrhea in TCM.

Nuclear Theranostics in Taiwan / 대한핵의학회잡지

Boron neutron capture therapy and Y-90 radioembolization are emerging therapeutic methods for uncontrolled brain cancers and hepatic cancers, respectively. These advanced radiation therapies are heavily relied on theranostic nuclear medicine imaging before the therapy for the eligibility of patients and the prescribed-dose simulation, as well as the post-therapy scanning for assessing the treatment efficacy. In Taiwan, the Taipei Veterans General Hospital is the only institute performing the BNCT and also the leading institute performing Y-90 radioembolization. In this article, we present our single institute experiences and associated theranostic nuclear medicine approaches for these therapies.

Outcomes of Fast-Track Multidisciplinary Care of Hip Fractures in Veterans: A Geriatric Hip Fracture Program Report

BACKGROUND: Hip fractures are a significant cause of morbidity and mortality in the elderly. Fast-track multidisciplinary co-management of these patients, rapid preoperative optimization, early surgery, and expeditious rehabilitation may minimize morbidity and mortality. In this study, we evaluated outcomes of fixation of hip fractures in the elderly patients managed by Geriatric Hip Fracture Program at a military hospital in India. METHODS: A total of 114 patients above 60 years of age with hip fractures were enrolled. They were comanaged by a team of specialists and fast-tracked to surgery. Independent ambulation with support of a walker was achieved before discharge to home. Patients were followed up for 1 year. RESULTS: The average age of the 114 patients was 77 years; 24 patients were octogenarian. Eighty-four percent of injuries were due to a domestic fall. Hypertension (41%) and diabetes (22%) were the most common comorbidities. All patients were optimized before surgery. The average delay from injury to admission was 1.7 days (range, 0 to 14 days) and that from admission to surgery was 1.8 days (range, 0 to 19 days). Hence, the average time from injury to surgery was 3.5 days. The length of stay in hospital was, as per rehabilitative milestones achieved, 2 to 5 days in 40% of the patients and 6 to 15 days in 60% of the patients. At 1 year after surgery, 95 patients were independently ambulant (56 patients with support and 39 patients without support). Twenty-three percent of the patients had postoperative complications and eight patients died (7.7%) at 1-year follow-up; 11 patients were lost to follow-up. CONCLUSIONS: Elderly hip fracture has a high risk of mortality (14%–58%). Thus, expeditious surgery within 24 hours of admission has been advocated in the Western literature to minimize mortality. Mortality rate at 1 year after surgery remains at 10% to 24%. In our study, even with aggressive co-management, the average delay to hip fracture fixation was more than 3 days; however, the 1-year mortality was relatively low (7.7%). This indicates the importance of preoperative optimization and postoperative rehabilitation for independent ambulation and mortality reduction in the elderly population.

Prevalence and Severity of Fecal Incontinence in Veterans

BACKGROUND/AIMS: Fecal incontinence (FI) is a common complaint that increases in prevalence with age. Our aim was to determine the prevalence of FI and assess its severity by self-report in a male-predominant Veteran outpatient clinic setting. METHODS: An anonymous 28 item questionnaire was administered to a convenience sample of veterans awaiting appointments. FI was defined as a loss of liquid or solid stool at least monthly. Multivariable logistic and linear models were used to identify predictors of FI prevalence and severity. RESULTS: One hundred thirty-three gastroenterology (GI) participants and 126 primary care (PC) participants completed the survey. Ninety-four of 259 participants (36.3%, 95% confidence interval [CI]: 30.4–42.5) reported an episode of FI (41.4% GI participants vs 31.0% PC participants; P = 0.078) with 33.6% having FI within the last 30 days (36.8% GI participants vs 30.2% PC participants; P = 0.122). Participants with more bowel movements per week (P = 0.005) and per day (P < 0.001) and with a higher Bristol Stool Scale form (P = 0.010) were more likely to have FI. Of participants with FI, mean Fecal Incontinence Severity Index score was 23.0 ± 9.5 with a significantly higher symptom score in GI participants compared to PC participants (25.2 ± 10.0 vs 20.1 ± 8.2; P = 0.011). Few participants had ever been asked by (35.0%) or evaluated by (18.0%) a doctor for FI symptoms. CONCLUSIONS: FI is a common complaint and under-recognized problem in the male-dominant Veteran population. Despite its prevalence, relatively few participants were asked about FI, with even less being treated. Due to the possible effects and implications on quality of life, more should be done to recognize this condition and arrange treatment.

Androgen deprivation therapy is associated with decreased second primary lung cancer risk in the United States veterans with prostate cancer / 한국역학회지

OBJECTIVES: We investigated whether androgen deprivation therapy (ADT) in prostate cancer patients was associated with a decreased risk for second primary lung cancer in US veterans. METHODS: Prostate cancer diagnoses in the US Veterans Affairs Cancer Registry between 1999 and 2008 were identified. Use of hormonal therapy and diagnoses of second primary lung cancer were determined from the registry. Synchronous prostate and lung cancers, defined as 2 diagnoses made within 1 year, were excluded from the analysis. Cancer-free survival was estimated using the Kaplan-Meier method and hazard ratios were estimated using Cox proportional hazard models. RESULTS: Among the 63,141 identified patients with prostate cancer, 18,707 subjects were eligible for the study. Hormonal therapy was used in 38% of patients and the median follow-up period was 28 months. ADT use was associated with longer lung cancer-free survival in prostate cancer patients (log-rank p=0.01). After adjusting for age, race, smoking and prostate cancer stage, ADT use was associated with decreased lung cancer risk by 15, 21, and 24% after 1, 2, and 3 years, respectively. CONCLUSIONS: ADT in prostate cancer patients may be associated with decreased second primary lung cancer risk among US veterans.

Trends and Appropriateness of Outpatient Prescription Drug Use in Veterans

OBJECTIVE: This study analyzed the national claims data of veterans to generate scientific evidence of the trends and appropriateness of their drug utilization in an outpatient setting. METHODS: The claims data were provided by the Health Insurance Review & Assessment (HIRA). Through sampling and matching data, we selected two comparable groups; Veterans vs. National Health Insurance (NHI) patients and Veterans vs. Medical Aid (MAID) patients. Drug use and costs were compared between groups by using multivariate gamma regression models to account for the skewed distribution, and therapeutic duplication was analyzed by using multivariate logistic regression models. RESULTS: In equivalent conditions, veteran patients made fewer visits to medical institutions (0.88 vs. 1), had 1.86 times more drug use, and paid 1.4 times more drug costs than NHI patients (p < 0.05); similarly, veteran patients made fewer visits to medical institutions (0.96 vs. 1), had 1.11 times more drug use, and paid 0.95 times less drug costs than MAID patients (p < 0.05). The risk of therapeutic duplication was 1.7 times higher (OR=1.657) in veteran patients than in NHI patients and 1.3 times higher (OR=1.311) than in MAID patients (p < 0.0001). CONCLUSION: Similar patterns of drug use were found in veteran patients and MAID patients. There were greater concerns about the drug use behavior in veteran patients, with longer prescribing days and a higher rate of therapeutic duplication, than in MAID patients. Efforts should be made to measure if any inefficiency exists in veterans' drug use behavior.

Penal provisions of Bioethics Law: problems and improvements

Chapter 9 of the Bioethics Law has several problems due to strict research standards and strong penalties. Therefore, biomedical researchers in Korea have raised several objections to this Law. To make matters worse, the normative power of the Law is significantly diminished because norms and penalties are divergent. Articles 2, 24, 26, 27, 28, and 32 of the Law require amendment because the current regulations on sperm retrieval, sperm management, and sperm use are insufficient. At a minimum, legislation for artificial insemination and in vitro fertilization should be consolidated. It is also necessary for sperm researchers and donors to be notified of their rights and duties. Section 9 of the Bioethics Law should therefore be amended. In particular, its legal formulation should be modified in order to enhance the effectiveness of bioethics law. This is in accord with the spirit of the Constitution. The principle of proportionality should be maintained. The statutory form should be revised to the level of abortion. Not only are the actors in embryo research diverse, including medical personnel, medical institutions, donors, veterans, and mediators, but embryo research involves multiple behavioral aspects, including intentional acts and negligence (violation of state duty). Excessively free-form activity is prescribed. Although the value of life is important, heavy punishment violates human dignity and human values. This legislation should not reflect to be grounded in emotional reactions such as anger.

One-year Survival Rates and Functional Recovery in Veterans Who Suffer from Hip Fractures: Evaluation of Commissioned Hospitals' System through Comparison between Veterans Hospitals and Commissioned Hospitals / 대한고관절학회지

PURPOSE: This study was performed to compare the: i) 1-year survival rate of patients with hip fractures, ii) factors affecting mortality in patients with hip fractures, and iii) results of functional recovery at commissioned hospitals (CH) and veterans hospitals (VH) to characterize the quality of care provided in the Korean commissioned hospital system. MATERIALS AND METHODS: The study population consisted of 183 veteran patients (84 and 99 treated at a single VH and 39 CH, respectively) who underwent hip fracture surgery between January 2010 and February 2015. This study compared baseline characteristics (i.e., age, comorbidities, fracture types and surgical treatment approaches) of the two groups vs. clinical outcomes, and evaluated the waiting time, length of hospital stay, total medical expenses, mortality rate within one year, and functional recovery at last follow up. RESULTS: There were no significant differences in age, fracture types, comorbidities, ambulatory status before fracture, waiting time, or length of hospital stay between the two groups, however, the total medical cost was higher in the CH group (P=0.009). There was no significant difference in mortality within one year after hip fracture (P=0.224) or functional recovery at last follow-up (P=0.463) between the two groups. CONCLUSION: The results of this study confirm that the Korean commissioned hospitals system is operating in accordance with its purpose. However, further studies are needed to better characterize the medical expenses of CHs vs. veterans hospitals.

Mediating Role of Psychological Capital in Relationship between Occupational Stress and Turnover Intention among Nurses at Veterans Administration Hospitals in Korea

PURPOSE: The aim of this study was to evaluate the mediating role of psychological capital (PCP) in the relationship between occupational stress and turnover intention in nurses. METHODS: Data were collected from a sample of 447 nurses working at four Veterans Administration Hospitals throughout South Korea from July 1 to July 31, 2014. We collected data from the nurses using the following surveys: the Short Form Korean-Occupational Stress Scale, the Korean version of the Turnover Intention Scale, and the Korean version of the Psychological Capital Questionnaire. Multiple linear regression analysis was performed to examine the mediating role of PCP. RESULTS: The level of occupational stress was 1.81 ± 0.23, the level of turnover intention was 3.29 ± 0.86, and the PCP level was 3.95 ± 0.52. There were significant correlations among the three variables (occupational stress, turnover intention, and PCP). PCP played a partial mediating role (β=−0.22, p = .008) in the relationship between occupational stress and turnover intention (p < .001) among nurses working at the Veterans Administration Hospitals. CONCLUSION: Based on the findings of this study, we recommend that South Korean hospitals offer occupational stress management programs that incorporate relevant programs in efforts to strengthen the overall components of PCP among nurses to reduce turnover intentions. Further studies are required to determine the most effective intervention programs for hospital settings.

The Formation of the Military Medical System of the Korean People's Army and the Military Medical Officer / 의사학

The military medical system of the Korean People's Army (KPA) first appeared in August 1946 when a central military hospita was established at the headquarters. Inside the KPA, the military medical and veteran services were first established in February 1948. The military medical officers of the KPA were those who were initially engaged in North Korea's health care sector. Most of the early military medical officers were those who had been trained in the Japanese medical system before liberation and were surgeons. After the establishment of the government in September 1948, Lee Dongwha rapidly introduced the medical system of the Soviet army into the KPA. The KPA military medical system was a mix of Soviet, Japanese and Chinese military medical systems. The medical section of the KPA was similar to that of the Japanese army, and the medical section of the lower army was similar to that of the Soviet army. The stretcher platoon of the KPA were similar to those of the Japanese and Chinese armies. The KPA mainly used Japanese medical equipment at the beginning, and after the establishment of the North Korean regime in September 1948, they were gradually replaced with Soviet products. The military medical office of the KPA were equipped with treatment rooms, laboratories, hospitals, pharmacy, and inpatient rooms. The military medical office purchased medical journals and specimens for medical research and set up a separate research fund. In addition, the military medical office was equipped with a laboratory for medical experiments and raised laboratory animals. The KPA military medical system was specialized in the fields of infectious disease prevention and preventive medicine. At the time, infectious disease in North Korea was mainly caused by bacteria and viruses in unsanitary living environments. The KPA set up a special anti-infectious disease department in consideration of the soldiers living in the collective facilities. The second characteristic of the KPA military medical system is preventive medicine. Since early 1946, North Korea has been interested in preventive medicine and has established various medical facilities and personnel. In line with this history of preventive medicine, the preventive department was installed in the KPA military medical system.

Trends in Microorganisms Isolated from Blood Cultures at a Veterans Hospital from 2012 to 2015

Blood culture is important to detecting bacteremia and fungemia in patients with suspected sepsis. We observed a four-year trend of blood culture isolates in the frequency by age group and in vitro antimicrobial susceptibility patterns obtained at VHS Medical Center, the largest veterans hospital in Korea. Blood cultures collected between 2012 and 2015 were analysed retrospectively. Of 68,352 blood specimens, 7,901 isolates were identified during the study period. Seventy-two percent of the isolates were gram-positive cocci, 18% were gram-negative rods, and 6% were fungi. The frequency of bacteremia/fungemia in patients who were 80–89 years old was 43.8%, the highest rate among all age groups, and the mean age of patients diagnosed by blood culture was 77 years old. Coagulase-negative staphylococcus (52.3%), Staphylococcus aureus (8.3%), enterococci (7.5%), Escherichia coli (6.4%), and Klebsiella pneumoniae (3.9%) were the bacteria most commonly isolated. The percentage of methicillin-resistant S . aureus increased in 2015 (76%) relative to that in 2012–2014 (63%–65%), and that of vancomycin-resistant Enterococcus faecium was 17%–22% with no significant changes through time. Among the gram-negative isolates, the ciprofloxacin resistance rate increased to 51.4% (E. coli ) and 31.1% (K. pneumoniae ) in 2015, but imipenem or ertapenem resistance was still very rare, with resistance rates of less than 0.5%. Acinetobacter baumannii showed a high rate of resistance (over 70%) to imipenem and ciprofloxacin throughout the study. In Pseudomonas aeruginosa , the resistance rates of imipenem and ciprofloxacin increased dramatically over time. This analysis confirmed a decrease in antimicrobial susceptibility of gram-negative rods isolated by blood culture.

What Is Important in Selecting a Designated Hospital for the Korean Veterans with Hip Fractures? / 대한고관절학회지

PURPOSE: The Korea Veterans Health Service (KVHS) implemented the ‘designated hospital system’ so that veterans can receive prompt medical attention at hospitals near their residences when experience medical emergencies, including hip fractures. We analyzed the hospital-selection process of Korean veterans following a hip fracture. We then evaluated (the validity and considerations) for choosing designated hospitals. MATERIALS AND METHODS: The study population consisted of 183 veteran patients (84 treated at a single veterans hospital and the remaining 99 treated at 39 designated hospitals) who underwent hip fracture between January 2010 and February 2015 in the Honam region of South Korea. The subjects were divided into the ‘nearest group’ (those who chose the hospital closest to their residences) and the ‘non-nearest group’ (those who did not choose the hospital closest to their residences). We compared the age, ambulatory status, combined disease and fracture type, factors that we speculated may impact hospital choice. RESULTS: Although the patients had difficulty moving due to hip fractures, 116 (63.4%) patients choose hospitals that were not closest to their residences. Patients with three or more comorbidities (P=0.028) and older ages (P=0.046) were statistically more likely to fall into the non-nearest group. Ambulatory status and fracture type were shown not to significantly impact choice between nearest and non-nearest hospital. Patients in the non-nearest group tended to seek care at larger hospitals. CONCLUSION: Korean veterans with hip fractures tended to seek care at larger hospitals, regardless of distance. We must therefore consider the number of beds and departments when choosing designated hospitals.
