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.

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.

BACKGROUND: In this study, state-owned medical institutes, industrial accident hospitals, veteran hospitals, and private medical clinics including 16 university medical institutes in the Seoul metropolitan area were selected to examine the causality of ethical management, positive psychological capital, and organizational effectiveness. METHODS: The study analyzed 1,056 valid questionnaires to which a total of 1,325 nurses, medical technicians, doctors, and administrative staff in 34 healthcare organizations answered over two months from June to August 2015. The study also utilized a ‘structural equation model,’ and a ‘hierarchical linear model’ to conduct the analysis. RESULTS: It was first found that ethical leadership, ethical management systems, and organizational ethics values, which are the three factors of ethical management, had significant influence on organizational commitment, and behavior. These are the three factors of employee organizational effectiveness. Second, ethical management, ethical leadership, ethical management systems, and organizational ethics values had significant influence on positive psychological capital. Third, positive psychological capital had significant influence on organizational commitment, turnover intention, and organizational citizenship behavior. Positive psychological capital presented an indirect effect on the relationship between the ethical management and organizational effectiveness of employees. The effect of positive psychological capital consisting of self-efficacy, hope, resilience, and optimism was confirmed in the healthcare organizations. Fourth, in relations among ethical management variables, ethical leadership showed a significant impact on ethical management systems, which had significant impacts on organizational ethics values, which had significant impacts on ethical leadership.

OBJECTIVES: Posttraumatic stress disorder(PTSD) has devastating effects on multiple aspects of the quality of life(QoL). Therefore, the purpose of this study is to compare the QoL between PTSD group and non-PTSD group, and identify the variables affecting the QoL of the Vietnam War veterans. METHODS: We recruited 39 veterans with PTSD and 43 veterans without PTSD, all of whom had deployed to the Vietnam War. We used the Korean version of Mini International Neuropsychiatric Interview-Plus, the Korean version of Clinician-Administered PTSD Scale, Combat Exposure Scale and the Korean version of World Health Organization Quality of Life Assessment Instrument abbreviated version. We used independent samples t-test to identify the differences between PTSD and non-PTSD group in each domains of the quality of life. We also used stepwise multiple linear regression analysis to figure out the variables affecting the QoL of the Vietnam War veterans. RESULTS: In the PTSD group, all domains of the QoL and the QoL total score(p<0.01) were significantly lower than those in the non-PTSD group. In the Vietnam War veterans, PTSD, major depressive disorder and education levels were the variables affecting the QoL. Among these, PTSD uniquely explained the QoL of the overall and general health(beta=-1.411, R2=0.180), the physical health domain(beta=-2.806, R2=0.089) and the total score (beta=-11.479, R2=0.104). CONCLUSIONS: These results suggest that among the Vietnam War veterans, the QoL of the PTSD group is significantly lower than that of the non-PTSD group. Among the combat exposed veterans, PTSD may be one of the main reasons that affect the multiple domains of the QoL.

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.

BACKGROUND: Lung nodules are frequently identified on imaging studies and can represent early lung cancers. We instituted the Lung Nodule Evaluation Team (LNET) to optimize management of these nodules by a lung specialist physician. All lung nodules identified by a radiologist prompted a direct consultation to this service. We report our initial experience with this process. METHODS: This is a retrospective review of patients with lung nodules at a single institution from 2008 to 2015. Since October 2014, lung nodules >3 mm identified on computed tomography (CT) scanning of the chest generate an automatic consult to LNET from the radiology service. Demographic, nodule and follow up data was entered into a surveillance database and summarized. RESULTS: There were 1,873 patients identified in the database. Of these, 900 patients were undergoing active surveillance. Consults increased from 5.5 to 93 per month after the start of the new consult program. Lung nodules were identified on 64% of chest CT scans. Prior to the direct radiology consult the average size of a nodule was 1.7 cm and 0.7 cm after. The overall time from initial nodule imaging to initiating a management plan by a thoracic specialist physician was 3.7 days. CONCLUSIONS Assessment of lung nodules by a specialist physician is important to ensure appropriate long term management and optimize utilization of diagnostic interventions. A direct radiology consult to a specialized team of chest physicians decreased the time in initiating a management plan, identified smaller nodules and may lead to a more judicious use of health care resources in the management of lung nodules.

Taiwan is aging fast, and so are neighborhood countries in eastern Asia. The rapid demographic transition triggers the need of developing elder-friendly health care system. However, developing geriatric services in eastern Asia was not as successful as western countries due to various reasons. In Taiwan, the development of geriatric services has been highly supported by the Veteran Affairs Commission in the past few years. Outpatient and inpatient geriatric services, as well as the post-acute care services have been successfully developed. The success of developing geriatric services in Taiwan was related to the development of geriatric specialty training program, which provided well-trained geriatricians for institutes to start new services. The success of specialty training programs also extended into clinical geriatric researches, especially the health service researches that proved the clinical benefits of outpatient, inpatient, post-acute and long-term care services with active participation of geriatricians. This review summarized the development of geriatric services and clinical geriatric researches in Taiwan in recent years.

OBJECTIVE: Post-traumatic stress disorder (PTSD) is often missed or incorrectly diagnosed in primary care settings. Although brief screening instruments may be useful in detecting PTSD, an adequate validation study has not been conducted with older adults. This study aimed to evaluate the reliability and validity of the Korean version of the primary care PTSD screen (PC-PTSD) and single-item PTSD screener (SIPS) in elderly veterans. METHODS: The PC-PTSD and SIPS assessments were translated into Korean, with a back-translation to the original language to verify accuracy. Vietnamese war veterans [separated into a PTSD group (n=41) and a non-PTSD group (n=99)] participated in several psychometric assessments, including the Korean versions of the PC-PTSD (PC-PTSD-K), SIPS (SIPS-K), a structured clinical interview from the Diagnostic and Statistical Manual of Mental Disorders-IV(SCID), and PTSD checklist(PCL). RESULTS: The PC-PTSD-K showed high internal consistency (Cronbach α=0.76), and the test-retest reliability of the PC-PTSD-K and SIPS-K were also high (r=0.97 and r=0.91, respectively). A total score of 3 from the PC-PTSD-K yielded the highest diagnostic efficiency, with sensitivity and specificity values of 0.90 and 0.86, respectively. The 'bothered a lot' response level from the SIPS-K showed the highest diagnostic efficiency, with sensitivity and specificity values of 0.85 and 0.89, respectively. CONCLUSION: Our findings suggest that both PC-PTSD-K and SIPS-K have good psychometric properties with high validity and reliability for detecting PTSD symptoms in elderly Korean veterans. However, further research will be necessary to increase our understanding of PTSD characteristics in diverse groups with different types of trauma.

PURPOSE: The objective was to study whether positive surgical margins (PSMs) predict biochemical recurrence (BCR) in all patients without adjuvant therapy after radical prostatectomy (RP). MATERIALS AND METHODS: We retrospectively reviewed the medical records of patients who underwent RP for prostate cancer at Veterans Health Service Medical Center from 2005 to 2011. BCR was defined by a prostate-specific antigen (PSA) value > or =0.2 ng/mL. The clinicopathological factors of the PSM group were compared with those of the negative surgical margin (NSM) group, and the predictive impact of a PSM for BCR-free survival were evaluated. In addition, we analyzed the prognostic difference for BCR-free survival between solitary and multiple PSMs. RESULTS: A PSM was noted in 167 patients (45.5%). BCR was reported in 101 men in total (27.5%). The BCR-free survival rate of the PSM group was lower than that of the NSM group (p<0.001). In a multivariate analysis for the total patients, PSM was significantly associated with BCR-free survival (p<0.001). After stratification by pathological T stage, Gleason score (GS), and preoperative PSA value, PSM was significantly predictive for BCR-free survival in men with pT2 and/or GS < or =6 or 7 and/or a PSA value <10 or 10-20 ng/mL (all p<0.05). Multiple PSMs were more predictive of BCR-free survival than was a solitary PSM (p=0.001). CONCLUSIONS: A PSM is a significant predictor of postoperative BCR in patients with pT2 and/or GS < or =7 and/or preoperative PSA <20 ng/mL. Multiple PSMs are considered a stronger prognostic factor for prediction of BCR than is a solitary PSM.

OBJECTIVES: Prospective evaluations of the associations between depressive symptoms and suicide deaths have been mainly performed in high-risk populations, such as individuals with psychiatric disorders or histories of self-harm. The purpose of this study was to prospectively examine whether more severe depressive symptoms assessed using the Geriatric Depression Scale (GDS) were associated with a greater risk of death from suicide in a general-risk population. METHODS: A total of 113 478 men from the Korean Veterans Health Study (mean age, 58.9 years) who participated in a postal survey in 2004 were followed up for suicide mortality until 2010. RESULTS: Over 6.4 years of follow-up, 400 men died by suicide (56.7 deaths per 100 000 person-years). More severe depressive symptoms were associated with greater risk of suicide death (p for trend <0.001). The unadjusted hazard ratios (HRs) in comparison to the absence of depression were 2.18 for mild depression, 2.13 for moderate depression, 3.33 for severe depression, and 3.67 for extreme depression. After adjusting for potential confounders, men with a potential depressive disorder had an approximate 90% higher mortality from suicide (adjusted HR, 1.92; 95% confidence interval [CI], 1.38 to 2.68; p<0.001) than men without depression. Each five-point increase in the GDS score was associated with a higher risk of death by suicide (adjusted HR, 1.22; p<0.001). The value of the area under the receiver operating characteristics curve of GDS scores for suicide deaths was 0.61 (95% CI, 0.58 to 0.64). CONCLUSIONS: Depressive symptoms assessed using the GDS were found to be a strong independent predictor of future suicide. However, the estimate of relative risk was weaker than would be expected based on retrospective psychological autopsy studies.
