RESUMO
BACKGROUND: To evaluate the drug prescription patterns for men diagnosed with benign prostatic hyperplasia (BPH) in Korea. METHODS: We extracted the data of 3% of the national patient samples including men aged ≥ 40 years between 2012 and 2017 from the Health Insurance Review and Assessment database and investigated the drugs prescribed for men with the BPH code N40. Men with a diagnosis of BPH but not receiving treatment were excluded. The primary outcome was the drugs prescribed and the changes in drug prescription pattern over 6 years for men first diagnosed with BPH. RESULTS: Alpha blockers were the most commonly prescribed drugs in men with BPH, and tamsulosin was the most common. The proportion of prescriptions increased steadily. The number of prescriptions for anticholinergics (ACH) increased, but decreased with the start of mirabegron prescriptions in 2015. Prescriptions of mirabegron are increasing rapidly and replacing ACH. Based on the prescription pattern by drug category, alpha blocker monotherapy decreased, whereas combination therapies such as alpha blocker + 5-alpha-reductase inhibitors (5ARI), and alpha blocker + 5ARI + ACH increased steadily. As for the number of prescriptions by drug ingredient, tamsulosin monotherapy was the most common, and the combination therapy of tamsulosin and mirabegron increased. CONCLUSION: Alpha blockers were the most commonly prescribed drug for men first diagnosed with BPH in Korea from 2012 to 2017, and tamsulosin was the most common alpha blocker. Prescriptions of combination therapy and mirabegron are gradually increasing.

PURPOSE: The purpose of this study was to evaluate end-of-life resource utilization and costs for prostate cancer patients during the last year of life in Korea. MATERIALS AND METHODS: The study used the National Health Information Database (NHIS-2017-4-031) of the Korean National Health Insurance Service. Healthcare claim data for the years 2002 through 2015 were collected from the Korean National Health Insurance System. Among 83,173 prostate cancer patients, we enrolled 18,419 after excluding 1,082 who never claimed for the last year of life. RESULTS: From 2006 to 2015, there was a 3.2-fold increase the total number of prostate cancer decedents. The average cost of care during the last year of life increased over the 10-year period, from 14,420,000 Korean won to 20,300,000 Korean won, regardless of survival time. The cost of major treatments and medications, other than analgesics, was relatively high. Radiologic tests, opioids, pain control, and rehabilitation costs were relatively low. Multiple regression analysis identified age and living in rural area as negatively associated with prostate cancer care costs, whereas income level and a higher number of comorbidities were positively associated. CONCLUSIONS: Expenditure of prostate cancer care during the last year of life varied according to patient characteristics. Average costs increased every year. However, the results suggest underutilization of support services, likely due to lack of alternative accommodation for terminal prostate cancer patients. Further examination of patterns of utilization of healthcare resources will allow policymakers to take a better approach to reducing the burden of prostate cancer care.
RESUMO
BACKGROUND: Two primary treatment methods are used for ruptured cerebral aneurysms, surgical clipping and endovascular coiling. In recent decades, endovascular coiling has shown remarkable progress compared to surgical clipping, along with technological developments. The aim of this study was to investigate the recent trends in treatments for ruptured cerebral aneurysms in Korea. METHODS: The data were obtained from the National Health Insurance database. We evaluated the trends in endovascular coiling and surgical clipping for ruptured aneurysms for the period 2000-2017. We obtained the number of prescriptions with International Classification of Diseases, 9th Revision, clinical modification codes related to nontraumatic subarachnoid hemorrhage and prescription codes S4641/4642 for surgical clipping and M1661/1662 for endovascular coiling. The medical expenses for each prescription were also obtained. The primary outcomes included the cumulative number of patients, patient rates per 100,000 people, and the correlation between patient rates and the percentage of the population in each age group. RESULTS: In the case of surgical clipping, there were no increasing or decreasing trends in the cumulative number of patients when the population/age group was ignored. When examining the trends in patient rates per 100,000 population at each year in male, there was no increasing or decreasing trend in the number of surgical clippings between the age groups, in spite of a decreasing tendency in the number of surgical clipping in male in their 40s and older than 60. In females, the surgical clipping rates tended to decrease only in patients older than 60 years, but there was no tendency to increase or decrease in the other ages. In contrast, the cumulative number of patients who underwent endovascular coiling for ruptured cerebral aneurysms increased year by year regardless of the population/age group. In both male and female, there was no increasing or decreasing trend only in the group aged 40 or younger and there was an increasing tendency in the rest of the age groups. In the trend of medical expenses, both the cost of surgical clipping and endovascular coiling showed increases. Specifically, the medical expense trend in endovascular coiling increased more rapidly than that for surgical clipping. CONCLUSION: There was a significant increase in the proportion of patients with ruptured aneurysms undergoing endovascular coiling between 2010 and 2017, whereas the use of surgical clipping decreased. The endovascular coiling was significantly increased in all age groups and surgical clipping was decreased in all age groups, especially in patients under 50 years of age.

BACKGROUND: A complete enumeration study was conducted to evaluate trends in national practice patterns and direct medical costs for prostate cancer (PCa) in Korea over a 10-year retrospective period using data from the Korean National Health Insurance Service. METHODS: Reimbursement records for 874,924 patients diagnosed between 2002 and 2014 with primary PCa according to the International Classification of Disease (ICD) 10th revision code C61 were accessed. To assess direct medical costs for patients newly diagnosed after 2005, data from 68,596 patients managed between January 2005 and 31 December 2014 were evaluated. RESULTS: From 2005 to 2014, the total number of PCa patients showed a 2.6-fold increase. Surgery and androgen deprivation therapy were the most common first-line treatment, alone or within the context of combined therapy. Surgery as a monotherapy was performed in 23.5% of patients in 2005, and in 39.4% of patients in 2014. From 2008, the rate of robot-assisted RP rose sharply, showing a similar rate to open RP in 2014. Average total treatment costs in the 12 months post-diagnosis were around 10 million Korean won. Average annual treatment costs thereafter were around 5 million Korean won. Out-of-pocket expenditure was highest in the first year post-diagnosis, and ranged from 12 to 17% thereafter. CONCLUSIONS: Between 2005 and 2014, a substantial change was observed in the national practice pattern for PCa in Korea. The present data provide a reliable overview of treatment patterns and medical costs for PCa in Korea.

INTRODUCTION: Changes in the surgical treatment of nephrolithiasis, owing to recent technical advances and innovations, have made treatments more effective and less invasive. In this retrospective, observational cohort study, we identified the changing trends in the treatment of nephrolithiasis. MATERIALS AND METHODS: We included patients with newly diagnosed nephrolithiasis who received any treatment in the United States, including extracorporeal shockwave lithotripsy (SWL), retrograde intrarenal surgery (RIRS), percutaneous nephrolithotomy (PCNL), and open surgery, from January 2007 to December 2014. Demographic factors, such as age, sex, region, surgical treatment type, and cost data, were analyzed. RESULTS: The median age of patients at treatment was 52 years, and the ratio of men and women was similar. There were definite changes in the trends of all treatment modalities (p < 0.01). Both the number and percentage tended to increase for RIRS, whereas for SWL, the number increased, but the percentage showed a steady decrease. In PCNL, both number and percentage increased to a minor degree. The overall cost of nephrolithiasis treatments during the study period nearly doubled (from $30,998,726 to $57,310,956). The number of treatments and average cost per treatment increased annually for each treatment modality. RIRS was the least expensive; the other procedures in decreasing order of their mean costs were as follows: SWL, PCNL, and open surgery. CONCLUSIONS: There was a gradual but constant change in treatment trends of nephrolithiasis, with an increasing trend for RIRS and a decreasing trend for SWL. Although PCNL has relatively invasive characteristics, it is still in steady demand.

IMPORTANCE: Use of robotic surgery has increased in urological practice over the last decade. However, the use, outcomes, and costs of robotic nephrectomy are unknown. OBJECTIVES: To examine the trend in use of robotic-assisted operations for radical nephrectomy in the United States and to compare the perioperative outcomes and costs with laparoscopic radical nephrectomy. DESIGN, SETTING, AND PARTICIPANTS: This retrospective cohort study used the Premier Healthcare database to evaluate outcomes of patients who had undergone robotic-assisted or laparoscopic radical nephrectomy for renal mass at 416 US hospitals between January 2003 and September 2015. Multivariable regression modeling was used to assess outcomes. EXPOSURES: Robotic-assisted vs laparoscopic radical nephrectomy. MAIN OUTCOMES AND MEASURES: The primary outcome of the study was the trend in use of robotic-assisted radical nephrectomy. The secondary outcomes were perioperative complications, based on the Clavien classification system, and defined as any complication (Clavien grades 1-5) or major complications (Clavien grades 3-5, for which grade 5 results in death); resource use (operating time, blood transfusion, length of hospital stay); and direct hospital cost. RESULTS: Among 23â¯753 patients included in the study (mean age, 61.4 years; men, 13â¯792 [58.1%]), 18â¯573 underwent laparoscopic radical nephrectomy and 5180 underwent robotic-assisted radical nephrectomy. Use of robotic-assisted surgery increased from 1.5% (39 of 2676 radical nephrectomy procedures in 2003) to 27.0% (862 of 3194 radical nephrectomy procedures) in 2015 (P for trend <.001). In the weighted-adjusted analysis, there were no significant differences between robotic-assisted and laparoscopic radical nephrectomy in the incidence of any (Clavien grades 1-5) postoperative complications (adjusted rates, 22.2% vs 23.4%, difference, -1.2%; 95% CI, -5.4 to 3.0%) or major (Clavien grades 3-5) complications (adjusted rates, 3.5% vs 3.8%, difference, -0.3%; 95% CI, -1.0% to 0.5%). The rate of prolonged operating time (>4 hours) for patients undergoing the robotic-assisted procedure was higher than for patients receiving the laparoscopic procedure in the adjusted analysis (46.3% vs 25.8%; risk difference, 20.5%; 95% CI, 14.2% to 26.8%). Robotic-assisted radical nephrectomy was associated with higher mean 90-day direct hospital costs ($19â¯530 vs $16â¯851; difference, $2678; 95% CI, $838 to $4519), mainly accounted for operating room ($7217 vs $5378; difference, $1839; 95% CI, $1050 to $2628) and supply costs ($4876 vs $3891; difference, $985; 95% CI, $473 to $1498). CONCLUSIONS AND RELEVANCE: Among patients undergoing radical nephrectomy for renal mass between 2003 and 2015, the use of robotic-assisted surgery increased substantially. The use of robotic-assistance was not associated with increased risk of any or major complications but was associated with prolonged operating time and higher hospital costs compared with laparoscopic surgery.

INTRODUCTION: Little is known about the impact of surgeon volume on the success of the robot-assisted partial nephrectomy (RAPN). The objective of this study was to compare the perioperative outcomes and cost related to RAPN by annual surgeon volumes. PATIENTS AND METHODS: Using the Premier Hospital Database, we retrospectively analyzed 39,773 patients who underwent RAPN between 2003 and 2015 in the United States. Surgeons for each index case were grouped into quintiles for each respective year. Outcomes were 90-day postoperative complications, operating room time (ORT), blood transfusion, length of stay, and direct hospital costs. Logistic regression and generalized linear models were used to identify factors predicting complications and cost. RESULTS: After accounting for patient and hospital demographics, high- and very high-volume surgeons had 40% and 42% decreased odds of having major complications (p = 0.045 and p = 0.027, respectively). Surgeons with higher volumes were associated with fewer odds of prolonged ORT (0.68 for low, 0.72 for intermediate, 0.56 for high, 0.44 for very high volume, all p < 0.05) and length of hospital stay (0.67 for intermediate, 0.51 for high, 0.45 for very high volume, all p < 0.01) compared with very low-volume surgeons. The 90-day hospital cost was also significantly lower for the surgeons with higher volume, but the statistical significance diminished after consideration of hospital clustering. CONCLUSION: Surgeons with very high RAPN volumes were found to have superior perioperative outcomes. Although cost of care appeared to correlate with surgeon volume, there may be other more influential factors predicting cost.

OBJECTIVE: To assess sexual function among women via self-evaluation of female sexual dysfunction (FSD) and to determine risk factors for FSD among Korean women. METHODS: A preliminary questionnaire-based study in Ansan, Korea, enrolled 935 women between January and December 2010. Participants completed the Female Sexual Function Index and a self-administered survey. Participants were divided into 2 groups: in the recognized group (RG), women were aware of their sexual problems; in the unrecognized group (URG), women were not. RESULTS: The prevalence of FSD was 46.1% (n=431). The prevalence of recognized FSD was 21.5% (n=201), whereas that of unrecognized FSD was 24.6% (n=230) Younger women showed a significantly more positive attitude toward sex compared with older individuals (P<0.001). Sexual desire, sexual arousal, dyspareunia, lubrication, and sexual satisfaction were factors of sexual dysfunction in the RG. In the URG, sexual arousal, sexual desire, orgasm, dyspareunia, and sexual satisfaction were identified as significant factors. CONCLUSION: Women in the RG had positive attitudes toward sex, whereas those in the URG had negative attitudes. Women who were unsatisfied with their sexual life did not express a need for treatment. The sociocultural background of Korean women should be considered in the diagnosis and treatment of FSD.
