Healthcare accreditation, which in the Republic of Korea is based on Article 58 of the Medical Service Act of July 2010, is an evaluation system designed to improve the quality of medical services and secure patient safety. Although ambulatory health organizations such as clinics comprise the majority of all health facilities, because they are not currently evaluated, securing quality and patient safety nationwide is not possible under the existing system. This article reviewed the accreditation programs of ambulatory health organizations in leading countries such as the United States and Australia in order to propose a successful model for Korea. The Accreditation Association for Ambulatory Health Care of the Unites States is a private, non-profit organization established in 1979. Similarly, Australian General Practice Accreditation Limited is a non-profit organization established in 1997 to deliver services to support general practices in Australia. Both are independent professional organizations and perform accreditation programs by a self-regulatory system. As healthcare quality improvement and accreditation have the characteristics of professional service activities, a self-regulatory approach rather than a government-controlled one, and process-oriented evaluation rather than structure-focused evaluation, are known to be effective. We expect an accreditation program for clinics in Korea to be established using a self-regulatory approach by an independent professional organization, not by the government, in the near future.

Purpose: The use of direct oral anticoagulants (DOACs) is challenging in fragile patients, including those with cancer, chronic kidney disease (CKD), and old age. We aimed to compare the safety of DOACs in terms of bleeding complications in these patients. Methods: Using hospital data from 2013 to 2019, we compared the risk of bleeding and major bleeding, including intracranial bleeding, any bleeding requiring transfusion, and all-cause bleeding, in patients with venous thromboembolism (VTE) who were naïve to DOAC (n = 12,369) and warfarin (n = 4,123). Hazard ratios (HRs) for the clinical outcomes were analyzed using Cox regression analysis, with warfarin as a reference. Results: The study included 4,078 eligible patients, predominantly female (54.1%), with a mean age of 62.5 years. DOACs were the primary treatment in 74.1% of the patients. DOAC treatment was associated with lower all-cause mortality compared to warfarin (HR, 0.799; 95% confidence interval [CI], 0.707–0.904). Although rates of recurrent VTE or major bleeding did not significantly differ between the groups, DOAC-treated patients had lower bleeding risk (HR, 0.562; 95% CI, 0.393–0.805; P = 0.002). The individual DOAC drugs did not differ significantly in terms of composite outcomes, recurrence, or bleeding events. Conclusion DOAC showed comparable outcomes with warfarin in the fragile patient population.

Venous thromboembolism (VTE), a severe condition comprising deep vein thrombosis and pulmonary embolism, requires prompt treatment. Traditional therapies include heparin, low-molecular-weight heparin, and warfarin. Direct oral anticoagulants (DOACs) such as dabigatran, rivaroxaban, apixaban, and edoxaban has revolutionized VTE management. Clinical trials show that DOACs are as effective as traditional anticoagulants in preventing recurrent VTE, with similar or lower rates of major bleeding. However, DOAC use is complex in vulnerable populations—those with comorbidities, chronic kidney disease, cancer, and advanced age—due to higher VTE and bleeding risks from polypharmacy and altered pharmacokinetics. Trials have shown promising results for DOACs, but these studies often include few patients from these high-risk groups. Moreover, while DOACs are validated for atrial fibrillation, these findings may not apply directly to patients with VTE due to different dosing. In this study, we aimed to address this gap by reviewing the literature on the efficacy and safety of DOACs in these vulnerable populations.

BACKGROUND AND OBJECTIVES: To evaluate the relationship between age and anesthesia method used for tympanostomy tube insertion (TTI) and to provide evidence to guide the selection of an appropriate anesthesia method in children. SUBJECTS AND METHODS: We performed a retrospective review of children under 15 years of age who underwent tympanostomy tube insertion (n=159) or myringotomy alone (n=175) under local or general anesthesia by a single surgeon at a university-based, secondary care referral hospital. Epidermiologic data between local and general anesthesia groups as well as between TTI and myringotomy were analyzed. Medical costs were compared between local and general anesthesia groups. RESULTS: Children who received local anesthesia were significantly older than those who received general anesthesia. Unilateral tympanostomy tube insertion was performed more frequently under local anesthesia than bilateral. Logistic regression modeling showed that local anesthesia was more frequently applied in older children (odds ratio=1.041) and for unilateral tympanostomy tube insertion (odds ratio=8.990). The cut-off value of age for local anesthesia was roughly 5 years. CONCLUSIONS: In a pediatric population at a single medical center, age and whether unilateral or bilateral procedures were required were important factors in selecting an anesthesia method for tympanostomy tube insertion. Our findings suggest that local anesthesia can be preferentially considered for children 5 years of age or older, especially in those with unilateral otitis media with effusion.

Purpose: The aim of this study was to investigate the relationship between the anatomical location of thrombi in the lower extremities and the development of pulmonary embolism (PE). Materials and Methods: We collected and analyzed the data of patients diagnosed with deep vein thrombosis (DVT) of the lower extremities between 2006 and 2015, and included those whose computed tomography (CT) data were available for PE identification. We evaluated the relationship between the laterality and the proximal/distal location of the thrombi in lower extremites and the location of PE. Results: CT images were available for 388/452 patients with DVT. After excluding 32 cases with bilateral involvement, 356 cases were included for analysis in this study. The ratio of DVT in the left:right leg was 232:124. PEs developed in 121 (52.2%) patients with left-sided DVT and in 78 (62.9%) with right-sided DVT (P=0.052). PEs in the main pulmonary arteries developed in 36 (15.5%) patients with left leg DVT and in 30 (24.2%) with right leg DVT (P=0.045). The most frequent site of thrombosis associated with the development of PE was the left iliac vein (59/199, 29.6%). According to the anatomical segment of the leg affected by DVT, patients with DVT in the right femoral vein (50/71, 70.4%; P=0.016) had the highest rate of occurrence of PE. Conclusion PE develops more frequently in patients with right-sided DVT than in those with left-sided DVT. Therefore, careful observation for the possible development of PE is recommended in cases with right-sided DVT of the lower extremity.

PURPOSE: The present study aimed to evaluate the risk factors and the role of graft material in the development of an acute phase systemic inflammatory response, and the clinical outcome in patients who undergo endovascular aneurysm repair (EVAR) or open surgical repair (OSR) of an abdominal aortic aneurysm (AAA). METHODS: We retrospectively evaluated the risk factors and the role of graft material in an increased risk of developing systemic inflammatory response syndrome (SIRS), and the clinical outcome in patients who underwent EVAR or OSR of an AAA. RESULTS: A total of 308 consecutive patients who underwent AAA repair were included; 178 received EVAR and 130 received OSR. There was no significant difference in the incidence of SIRS between EVAR patients and OSR patients. Regardless of treatment modality, SIRS was observed more frequently in patients treated with woven polyester grafts. Postoperative hospitalization was significantly prolonged in patients that experienced SIRS. In multivariate analyses, the initial white blood cell count (P = 0.001) and the use of woven polyester grafts (P = 0.005) were significantly associated with an increased risk of developing SIRS in patients who underwent EVAR. By contrast, the use of woven polyester grafts was the only factor associated with an increased risk of developing SIRS in patients who underwent OSR, although this was not statistically significant (P = 0.052). CONCLUSION: The current study shows that the graft composition plays a primordial role in the development of SIRS, and it leads to prolonged hospitalization in both EVAR and OSR patients.

BACKGROUND AND PURPOSE: This study evaluated the outcome following surgery for carotid artery stenosis in a single institution during a 10-year period and the relevance of aging to access to surgery. METHODS: Between January 2001 and December 2010, 649 carotid endarterectomies (CEAs) were performed in 596 patients for internal carotid artery occlusive disease at our institution; 596 patients received unilateral CEAs and 53 patients received bilateral CEAs. Data regarding patient characteristics, comorbidities, stroke, mortality, restenosis, and other surgical complications were obtained from a review of medical records. Since elderly and high-risk patients comprise a significant proportion of the patient group undergoing CEAs, differences in comorbidity and mortality were evaluated according to age when the patients were divided into three age groups: <70 years, 70-79 years, and > or =80 years. RESULTS: The mean age of the included patients was 67.5 years, and 88% were men. Symptomatic carotid stenosis was observed in 65.7% of patients. The rate of perioperative stroke and death (within 30 days of the procedure) was 1.84%. The overall mortality rate was higher among patients in the 70-79 years and >80 years age groups than among those in the <70 years age group, but there was no significant difference in stroke-related mortality among these three groups. CONCLUSIONS: CEA over a 10-year period has yielded acceptable outcomes in terms of stroke and mortality. Therefore, since CEA is a safe and effective strategy, it can be performed in elderly patients with acceptable life expectancy.
