Objectives: This study aimed to quantify the actual resource utilization and cost structure of homevisit oral health care services using a Time-Driven Activity-Based Costing (TDABC) approach, in response to the growing demand for efficient home-based care for older adults. Methods: An analytical framework comprising 12 domains and 78 activities, validated through a Delphi study, was applied to home‑visit oral health care records. A total of 100 home‑visit service logs recorded by ten dental hygienists participating in an integrated care program in Cheonan City between March and April 2024 were analyzed. Data collected included activity time, consumable supply, travel time and distance, and transportation expenses. A capacity cost rate incorporating both direct and indirect costs was used to estimate activity‑level costs and total costs per visit. Results: Dental hygienists conducted an average of 6.43 visits per day. The mean travel time and distance per visit were 15.04 min and 7.31 km, respectively. Transportation expenses averaged 9,740 KRW per visit, and consumable supply costs ranged from 1,428 to 9,738 KRW per patient, depending on oral health status. The calculated capacity cost rate was 487 KRW/min, resulting in activity-based costs of 66,232 KRW per visit across the 78 activities. When transportation time costs were added (7,324 KRW; 15.04 min×487 KRW/min), the total cost per visit was estimated at 73,556 KRW. Preparation and infection control activities were identified as major cost drivers. Conclusions The TDABC approach provided a comprehensive estimate of the cost structure of home-visit oral health care services, capturing expenditures associated with travel, preparation, and documentation. These findings provide evidence to support sustainable reimbursement models within long-term care and integrated care systems.

Objectives: This qualitative study explores the perspectives of dental hygienists and examines factors influencing payment structures in a community home-based oral health care intervention program. Methods: Focus group interviews were conducted on October 26, 2023, in a quiet study room over 120 minutes. Intervention providers who participated in the older adults medical care integration support program were included in this study. Their ages ranged from 25 to 57 years, with experience in home-based oral healthcare spanning from 1.5 to 5 years. Voice recordings of the interviews were transcribed using Clova Note and Naver’s AI transcription tool. Subsequently, the ‘Word Cloud Generator 3.7’ program was employed to extract, visualize, and analyze frequently mentioned words and key concepts from the responses. Results Semantic analysis identified 61 significant keywords and 10 subcategories, categorized into four main themes: ‘oral health challenges in the elderly,’ ‘work system of home-based dental hygienists,’ ‘needs and realities of home-based oral care,’ and ‘payment and compensation frameworks.’ Conclusions: To address the demands of a super-aging society, it is imperative to establish a standardized oral healthcare cost system for home-based interventions, supported by clear laws and regulations.

Objectives: Children and adolescents have a high prevalence of dental caries, primarily due to negligent oral care, frequent snack intake, and inadequate attention to oral disease prevention.Therefore, ensuring oral care and preventing dental caries during this period is essential. Economic barriers, particularly in low- and middle-income countries like the Philippines, limit access to dental care, highlighting the need for national oral health programs. Methods: This study aimed to investigate the oral health status of children in selected areas of the Philippines and to generate basic data for effective oral health promotion programs. We compared the oral health statuses of enrolled and newly enrolled students in schools with school-based dental clinics. Results: The results indicated that the prevalence of caries and the average number of carious permanent teeth were lower in enrolled students than in new students. Conclusions This finding suggests that school-based oral healthcare programs effectively improve children’s oral health and that introducing school-based dental clinics and establishing efficient systems are essential for improving oral health in low- and middle-income countries.

Background: The objective of this study was to investigate the trend of self-injurious behavior (SIB) among persons who were directly impacted by coronavirus disease 2019 (COVID-19), especially those with pre-existing mental disorders. Methods: Using the National Health Insurance Service-COVID-19 database cohort, the monthly SIB rate was calculated by COVID-19 subgroups (i.e., positive for COVID-19 test, negative for COVID-19 test, and non-COVID-19 test [control]). In addition, moderated regression analysis was utilized to examine the statistical difference of SIB (suicide attempt and non-suicidal self-injury using ICD-10 code) trend between COVID-19 subgroups and with and without pre-existing mental disorder. Results: A total of 328,373 persons were included in the cohort study. Of these, 212,678 had been tested for COVID-19, and 7,713 of them were confirmed positive. During the pandemic peak, the “negative for COVID-19” group showed a large increase (P = 0.003) in SIB rates compared to the control group, the “positive for COVID-19” group showed a decreasing trend, but not significant (P = 0.314). Among those who were tested for COVID-19, those with pre-existing mental disorders showed an increasing trend of SIB compared to those without pre-existing mental disorders, however statistically insignificant (P= 0.137). Conclusion Our results suggest that people who are tested for COVID-19 are at a high risk of SIB during the peak COVID-19 pandemic. Therefore, screening for suicide risk and psychological interventions is needed for these high-risk groups.

Objective: To investigate the cumulative effect of antipsychotics at different dosages on mortality in patients with schizophrenia. Methods: We analyzed data from the Korean National Health Insurance System−National Sample Cohort covering the 2002−2013 period. We used Cox regression analysis to calculate hazard ratios for mortality risks according to cumulative antipsychotic exposure levels (low, moderate, and high). Results: Our analyses revealed no significant association between antipsychotic exposure and mortality (either all-cause or cause-specific) in patients with schizophrenia. Conclusion Our results imply that the excess mortality of patients with schizophrenia is attributable to factors other than antipsychotic usage.

Treatment options for children with end-stage heart failure are limited. We report the first case of a successful pediatric heart transplantation bridged with a durable left ventricular assist device in Korea. A 10-month-old female infant with dilated cardiomyopathy and left ventricular non-compaction was listed for heart transplantation. During the waiting period, the patient’s status deteriorated. Therefore, we decided to provide support with a durable left ventricular assist device as a bridge to transplantation. The patient was successfully bridged to heart transplantation with effective support and without any major adverse events.

A febrile respiratory infectious disease unit (FRIDU) with a negative pressure ventilation system was constructed outside the emergency department (ED) of the Samsung Medical Center in 2015, to screen for patients with contagious diseases requiring isolation. We evaluated the utility of the FRIDU during 1 year of operation. We analyzed 1,562 patients who were hospitalized after FRIDU screening between August 2015 and July 2016. The level of isolation recommended during their screening at the FRIDU was compared with the level deemed appropriate given their final diagnosis. Of the 1,562 patients screened at the FRIDU, 198 (13%) were isolated, 194 (12%) were reverse isolated, and 1,170 (75%) were not isolated. While hospitalized, 97 patients (6%) were confirmed to have a contagious disease requiring isolation, such as tuberculosis; 207 patients (13%) were confirmed to be immunocompromised and to require reverse isolation, mainly due to neutropenia; and the remaining 1,258 patients (81%) did not require isolation. The correlation coefficient for isolation consistency was 0.565 (P < 0.001). The sensitivity and negative predictive value of FRIDU screening for diagnosing contagious disease requiring isolation are 76% and 98%, respectively. No serious nosocomial outbreaks of contagious diseases occurred. During FRIDU screening, 114 patients were admitted to the resuscitation zone due to clinical instability, and three of these patients died. The initial isolation levels resulting from FRIDU screening were moderately well correlated with the isolation levels required by the final diagnosis, demonstrating the utility of pre-hospitalization screening units. However, the risks of deterioration during the screening process remain challenges.
