RESUMEN
Background: The 2014 European Respiratory Society/American Thoracic Society guidelines defined severe asthma based on treatment intensity and estimated the proportion of severe asthma among all asthma cases to be 5-10%. However, data supporting the estimate and comprehensive and sequential data on asthma cases are scarce. We aimed to estimate the national prevalence and proportion of severe asthma during the last decade. Methods: Using a Japanese national administrative database, which covers ≥99% of the population, we evaluated the prevalence and proportion of severe asthma in 2013, 2015, 2017 and 2019. Additionally, we elucidated the demographic characteristics, treatments and outcomes of patients with asthma. Results: The national prevalence of mild-moderate and severe asthma in 2019 was 800 and 36 per 100 000 persons, respectively. While the prevalence of mild-moderate asthma remained almost constant in the study years, the prevalence of severe asthma decreased, resulting in a reduction in the proportion of severe asthma from 5.6% to 4.3%. Although treatment modalities have evolved, such as the increased use of combination inhalers and asthma biologics, approximately 15% of mild-moderate and 45% of severe asthma cases were still considered "uncontrolled". The number of deaths from asthma decreased in patients with both mild-moderate and severe asthma. Conclusions: This study revealed that the prevalence of severe asthma in Japan decreased during the study period and fell below 5% in the most recent data. Despite treatment evolution, a substantial proportion of patients with both mild-moderate and severe asthma still have poor asthma control.
RESUMEN
OBJECTIVES: Although intrapleural administration of fibrinolytics is an important treatment option for the management of empyema, the addition of fibrinolytics failed to reduce the need for surgery and mortality in previous randomized controlled trials. This study aimed to investigate the effects of administrating fibrinolytics in the early phase (within 3 days of chest tube insertion) of empyema compared with late administration or no administration. METHODS: We used the Japanese Diagnosis Procedure Combination Inpatient Database to identify patients aged ≥16 years who were hospitalized and underwent chest tube drainage for empyema. A 1:2 propensity score matching and stabilized inverse probability of treatment weighting were conducted. RESULTS: Among the 16 265 eligible patients, 3082 and 13 183 patients were categorized into the early and control group, respectively. The proportion of patients who underwent surgery was significantly lower in the early fibrinolytics group than in the control group; the odds ratio (95% confidence interval) was 0.69 (0.54-0.88) in the propensity score matching (P = 0.003) and 0.64 (0.50-0.80) in the stabilized inverse probability of treatment weighting analysis (P < 0.001). All-cause 30-day in-hospital mortality, length of hospital stay, duration of chest tube drainage, and total hospitalization costs were also more favourable in the early fibrinolytics group. CONCLUSIONS: The early administration of fibrinolytics may reduce the need for surgery and death in adult patients with empyema.

This study aims to investigate the impact of dental care utilization status on the occurrence of fatal complications such as cerebral/cardiovascular disease (CVD) and infectious diseases in patients with end-stage renal disease (ESRD) undergoing hemodialysis. This retrospective cohort study was performed using the Japanese claims database and included patients who first underwent hemodialysis between April 2014 and September 2020. The exposure variable of interest was the pattern of dental utilization, which was categorized into three groups, "dental treatment group", "preventive dental care group", and "no-dental visit group". The primary outcomes were the time interval until a composite end point of first major cardiovascular event (acute myocardial infarction, heart failure, or cerebral infarction) of infectious disease (pneumonia and sepsis). The secondary outcomes were the time interval until the incidence of each component of primary outcomes. Survival analyses, including log-rank tests and Cox proportional hazards regression analyses, were performed. Among the 10,873 patients who underwent the first dialysis treatment, 6152 were assigned to the no-dental visit group, 2221 to the dental treatment group, and 2500 to the preventive dental care group. The preventive dental care group had significantly lower hazard ratios (HRs) of the incidence of CVD (adjusted hazard ratio [aHR]: 0.86, 95% confidence interval [CI]: 0.77-0.96) and infectious diseases (aHR: 0.86, 95% CI: 0.76-0.97). As for pneumonia, preventive dental care and dental treatment groups had significantly lower HRs (aHR: 0.74 and 0.80, 95% CI: 0.61-0.88, 0.66-0.96) than the no-dental visit group. This study demonstrated that dental visits for preventive dental care were associated with a significant risk reduction in CVD and infectious complications in patients with ESRD undergoing hemodialysis.

BACKGROUND: Similar to metformin, dipeptidyl peptidase-4 inhibitors (DPP-4 Is), glucagon-like peptidase 1 receptor agonists (GLP-1 RAs), and sodium glucose co-transporter-2 inhibitors (SGLT-2 Is) may improve control of asthma owing to their multiple potential mechanisms, including differential improvements in glycemic control, direct anti-inflammatory effects, and systemic changes in metabolism. OBJECTIVE: To investigate whether these novel antihyperglycemic drugs were associated with fewer asthma exacerbations compared with metformin in patients with asthma comorbid with type 2 diabetes. METHODS: Using a Japanese national administrative database, we constructed 3 active comparators-new user cohorts of 137,173 patients with a history of asthma starting the novel antihyperglycemic drugs and metformin between 2014 and 2022. Patient characteristics were balanced using overlap propensity score weighting. The primary outcome was the first exacerbation requiring systemic corticosteroids, and the secondary outcomes included the number of exacerbations requiring systemic corticosteroids. RESULTS: DPP-4 Is and GLP-1 RAs were associated with a higher incidence of exacerbations requiring systemic corticosteroids compared with metformin (DPP-4 Is: 18.2 vs 17.4 per 100 person-years, hazard ratio: 1.09, 95% confidence interval [CI]: 1.05-1.14; GLP-1 RAs: 24.9 vs 19.0 per 100 person-years, hazard ratio: 1.14, 95% CI: 1.01-1.28). In contrast, the incidence of exacerbations requiring systemic corticosteroids was similar between the SGLT-2 Is and metformin groups (17.3 vs 18.1 per 100 person-years, hazard ratio: 1.00, 95% CI: 0.97-1.03). While DPP-4 Is and GLP-1 RAs were associated with more exacerbations requiring systemic corticosteroids, SGLT-2 Is were associated with slightly fewer exacerbations requiring systemic corticosteroids (53.7 vs 56.6 per 100 person-years, rate ratio: 0.95, 95% CI: 0.91-0.99). CONCLUSIONS: While DPP-4 Is and GLP-1 RAs were associated with poorer control of asthma compared with metformin, SGLT-2 Is offered asthma control comparable to that of metformin.

BACKGROUND: Using patient registries or limited regional hospitalization data may result in underestimation of the incidence and prevalence of rare diseases. Therefore, we used the national administrative database to estimate the incidence and prevalence of lymphangioleiomyomatosis over six years (2014-2019) and describe changes in clinical practice and mortality. METHODS: We extracted data from the National Database of Health Insurance Claims and Specific Health Checkups of Japan between January 2013 and December 2020. This database covers ≥99% of the population. We used the diagnostic code for lymphangioleiomyomatosis to estimate the incidence and prevalence from 2014 to 2019. Additionally, we examined the demographic characteristics, treatments, comorbidities, and mortality of the patients. RESULTS: In women, the incidence and prevalence of lymphangioleiomyomatosis in 2019 were approximately 3 per 1,000,000 person-years and 28.7 per 1,000,000 persons, respectively. While, in men, the incidence and prevalence of lymphangioleiomyomatosis were <0.2 per 1,000,000 person-years and 0.8 per 1,000,000 persons, respectively. From 2014 to 2019, the proportion of prescriptions of sirolimus and everolimus increased, while the use of home oxygen therapy, chest drainage, comorbid pneumothorax, and bloody phlegm decreased. The mortality rate remained stable at approximately 1%. CONCLUSIONS: The incidence and prevalence of lymphangioleiomyomatosis were higher in women than those reported previously. Although the incidence did not change during the 6-year period, the prevalence gradually increased. Moreover, lymphangioleiomyomatosis was observed to be rare in men. The practice of treating patients with lymphangioleiomyomatosis changed across the six years while mortality remained low, at approximately 1%.

BACKGROUND: Dental caries are a common non-communicable disease among children. As a public health measure at the prefectural level, school-based fluoride mouth-rinse (S-FMR) program, medical/dental expense subsidy policies, and other factors may reduce the incidence of dental caries and tooth loss. Prefectures focusing on promoting oral health policies may promote both, but the interaction effect of implementing both subsidy policies and S-FMR at the prefectural level on caries prevention has not yet been examined. METHODS: We conducted an ecological study using two-wave panel data, prefecture-level aggregated data in Japan for 2016 and 2018. Coefficient and 95% confidence intervals (CI) were calculated for the dependent variables for oral health using mixed-effects linear regression analysis adjusted for possible confounders. Two dependent variables were used; the standardized claim ratio (SCR) of deciduous tooth extraction and 12-year-olds' decayed, missing, or filled permanent teeth (DMFT). Four independent variables were S-FMR, the SCR of dental sealants, prefectural income per person, and subsidy policy in three models: co-payment until children enter elementary school (n = 23), no co-payment until children enter elementary school (n = 7), and co-payment continuing beyond elementary school (n = 17). The effects of six interaction terms, each representing a unique pairing from the four independent variables, were individually calculated. RESULTS: S-FMR was negatively associated with the SCR of deciduous tooth extractions and DMFT (coefficient = -0.11, 95% CI -0.20; -0.01 and coefficient = -0.003, 95% CI -0.005; -0.001, respectively). No co-payment until children enter elementary school was positively associated with the SCR of deciduous tooth extraction compared to co-payment until children enter elementary school(coefficient = 11.42, 95% CI 3.29; 19.55). SCR of dental sealants was positively associated with the SCR of deciduous tooth extractions (coefficient = 0.12, 95% CI 0.06; 0.19) but negatively associated with DMFT (coefficient = -0.001, 95% CI -0.003; -0.0001). Per capita prefectural income was positively associated with the SCR of deciduous tooth extractions(coefficient = 0.01, 95% CI 0.001; 0.02). No interaction was found between S-FMR and the subsidy policy at both outcomes. CONCLUSION: High S-FMR utilization and no co-payment until children enter elementary school were associated with fewer deciduous tooth extractions. Also, S-FMR and dental sealant were associated with decreased DMFT.

AIM: This study aimed to elucidate the impact of periodontal therapy on glycaemic control in individuals with type 2 diabetes and various baseline blood glucose levels using a large-scale claims database from Japan. MATERIALS AND METHODS: Using the JMDC Claims Database, we identified individuals with type 2 diabetes who underwent health check-ups in the fiscal years 2018 or 2019 and were followed up until the next year's health check-up. We conducted a weighted cohort analysis using stabilized inverse probability weights for treatment and censoring to estimate the effect of periodontal therapy on changes in haemoglobin A1c levels within a year. Analysis was done for different baseline haemoglobin A1c categories: 6.5%-6.9%, 7.0%-7.9% and ≥8.0%. RESULTS: Of the 4279 insured persons included in the study, 957 received periodontal therapy. Overall, there was a tendency towards improved glycaemic control among those who received periodontal therapy. Participants with baseline haemoglobin A1c levels of 7.0%-7.9% who received periodontal therapy exhibited significantly better glycaemic control compared with those without dental visits (difference; -0.094 [95% confidence interval: -0.181 to -0.007]). CONCLUSIONS: Periodontal therapy may improve glycaemic control in individuals with diabetes, especially in those with haemoglobin A1c levels ≥7.0%.

OBJECTIVES: With the increasing number of family caregivers due to the ageing population, physical and mental health problems among caregivers are of concern. However, few studies have evaluated their oral health. This study aimed to evaluate the association between being a family caregiver and recent dental visits for dental symptoms in Japan, with consideration of gender. METHODS: A cross-sectional study was conducted using the 2016 Comprehensive Survey of Living Conditions (CSLC) in Japan. Participants with dental symptoms were included in this study. The primary outcome was recent dental visits. The exposure variable of interest was being a primary caregiver for a family member requiring long-term care. A logistic regression analysis was conducted adjusting for contributing factors such as age, gender, marital status, working hours per week, education, household expenditure per month, self-rated health and the interaction between gender and caregiving. A stratified analysis by gender was also performed. RESULTS: Of the 5100 eligible participants, 233 (4.6%) were family caregivers. Of all participants, 2746 (53.8%) reported dental visits. The adjusted odds ratio (aOR) of family caregivers having recent dental visits was 0.83 (95% confidence interval [CI], 0.64-1.09). In a gender stratified analysis, family caregivers were less likely to visit dental clinics than were non-family caregivers in the male subsample (aOR: 0.56, 95% CI: 0.34-0.92) but not in the female subsample (aOR: 0.99, 95% CI: 0.72-1.38). CONCLUSIONS: The findings indicate that family caregivers, especially male caregivers, had fewer dental visits than non-family caregivers. These findings suggest the need to improve the accessibility of dental clinics to family caregivers with dental symptoms.
RESUMEN
BACKGROUND: Pneumonia is a leading cause of death worldwide. It is a particularly serious burden in older people, as they tend to have a weakened immune response. Identifying the role of oral self-care and pneumococcal vaccination in healthy, independent older people can aid pneumonia prevention among them. This study investigated the associations between oral self-care, pneumococcal vaccination, and pneumonia experience among independent older people. METHODS: This cross-sectional study used data from the 2016 Japan Gerontological Evaluation Study. We used machine learning to examine the association between oral self-care and the experience of pneumonia over the previous year, stratified by pneumococcal vaccination. The covariates were sex, age, years of education, equivalent annual income, medical history of stroke, oral health status (choking, dryness, number of teeth), and smoking status. The analysis included 17 217 independent older people aged 65 and over. RESULTS: The prevalence of pneumonia experienced among those who brushed their teeth once or less per day was 4.5% and 5.3% for those with and those without pneumococcal vaccinations, respectively. In the unvaccinated group, the odds ratio of pneumonia experience for those who brushed their teeth once or less a day was 1.57 (95% confidence interval: 1.15-2.14) compared to those who brushed their teeth 3 or more times a day. By contrast, there was no significant association between the frequency of toothbrushing and the experience of pneumonia among people who received pneumococcal vaccination. CONCLUSIONS: Oral care influenced the experience of pneumonia among independent older people who did not receive pneumococcal vaccination.

BACKGROUND: This study aimed to provide a stratified description of dental visit utilisation by Japanese residents based on patient age, sex, prefecture, and the purpose of the visits. METHODS: This cross-sectional study used the National Database of Health Insurance Claims of Japan to identify participants visiting dental clinics in Japan (April 2018-March 2019). Dental care utilisation by populations stratified by age, sex, and prefecture was assessed. We estimated the slope index of inequality (SII) and relative index of inequality (RII) to evaluate regional differences based on regional income and education. RESULTS: Amongst the Japanese population, 18.6% utilised preventive dental care visits; 59,709,084 participants visited dental clinics, with children aged 5 to 9 years having the highest proportion. SII and RII were higher for preventive dental visits than those for treatments in all settings. The largest regional differences for preventive care were observed in SII of children aged 5 to 9 years and in RII of men in their 30s and women aged 80 years and older. CONCLUSIONS: This nationwide population-based study revealed that the proportion of people utilising preventive dental care in Japan was low, with regional differences. Preventive care needs to be more easily accessible and available to improve the oral health of residents. The above findings may provide an important basis for improving policies related to dental care for residents.

OBJECTIVES: Dental check-ups at the workplace provide the opportunity for early detection of dental diseases. Dental check-ups during working hours could reduce the number of days of absence from work due to visits to dental clinics outside the workplace. Although health check-ups are provided to workers in Japan, dental check-ups is not mandatory. This study aimed to determine the association between the place of dental check-ups and absenteeism due to visits to the dental clinic. METHODS: This cross-sectional study used data from an online self-reported worker survey conducted for 2 weeks in March 2017. We applied linear regression analysis with robust variance to determine the association between the place of dental check-ups and absenteeism due to dental clinic visits while adjusting for sociodemographic, health, and oral health covariates. RESULTS: The average age of the 3930 participants was 43.3 ± 11.7 years, and 52.3% were male. The number of days of absenteeism due to dental clinic visits in the past year for those who received check-ups only at the dental clinic and at the workplace were 0.57 ± 2.67 days and 0.21 ± 1.20 days, respectively. After adjusting for covariates, it was found that those who received dental check-ups at the workplace had 0.35 (95% CI, 0.12-0.58) fewer days of absence than those who received dental check-ups at the dental clinic. CONCLUSION: Workers who received dental check-ups at the workplace were associated with fewer days of absence due to dental visits than those who received at the dental clinic.

Despite the general recognition of economic factors as fundamental upstream social determinants of health inequalities, interventions to improve health and reduce inequalities tend to focus on proximal health determinants. However, recent socioeconomic crises have increased the focus on economic factors. Health-related approaches to address economic factors can be divided into two categories: (1) indirect approaches, such as financial support for obtaining dental care and fiscal policies targeting unhealthy commodities and (2) direct approaches, such as cash transfers or provision of a universal basic income. For indirect approaches, policies reducing out-of-pocket payments for dental care appear to improve access to services and reduce oral health inequalities. Price policies targeting tobacco and sugar through taxation are associated with declines in periodontal disease and caries, and sugar taxation appears to reduce oral health inequalities. As regards direct approaches, studies on cash transfers to low-income individuals have found no positive impact on dental visits, while results in relation to caries prevention were inconclusive. No dental studies examined the effect of a population approach to income security, such as basic income. Research on economic interventions for oral health inequalities is scarce, and studies using causal inference methods and natural experiments are urgently needed.

Objectives: We examined the relationship between consolidation of delivery and the workload of obstetricians working at perinatal centers. Methods: We conducted a descriptive analysis using perinatal care areas classified into three types (metropolitan, provincial, and rural). We calculated the Herfindahl-Hirschman Index (HHI) as an index of consolidation and the proportion of the deliveries at clinics as an indicator of the low-risk deliveries and the deliveries per center obstetrician as an indicator of obstetricians' workload. We used >150 deliveries yearly as an excess indicator. The correlation between the HHI and obstetricians' workload and the proportion of deliveries at clinics was examined using the Pearson correlation coefficient. Results: The proportion of areas with >150 deliveries yearly was higher in the consolidated areas. In provincial areas, obstetricians' workload was positively correlated with the HHI and was negatively correlated with the proportion of deliveries at clinics. Conclusions: The obstetricians' workload may be increasing where more consolidation occurs. In provincial areas, the center obstetrician's workload could be reduced not only by consolidation but also by sharing the role of handling low-risk deliveries with clinics and hospitals with obstetric units other than perinatal centers.
RESUMEN
Background: Cardiac rehabilitation (CR) is an evidence-based medical service for patients with acute myocardial infarction (AMI); however, its implementation is inadequate. We investigated the provision status and equality of CR by hospitals in Japan using a comprehensive nationwide claims database. MethodsâandâResults: We analyzed data from the National Database of Health Insurance Claims and Specific Health Checkups in Japan for the period April 2014-March 2016. We identified patients aged ≥20 years with postintervention AMI. We calculated hospital-level proportions of inpatient and outpatient CR participation. The equality of hospital-level proportions of inpatient and outpatient CR participation was evaluated using the Gini coefficient. We included 35,298 patients from 813 hospitals for the analysis of inpatients and 33,328 patients from 799 hospitals for the analysis of outpatients. The median hospital-level proportions of inpatient and outpatient CR participation were 73.3% and 1.8%, respectively. The distribution of inpatient CR participation was bimodal; the Gini coefficients of inpatient and outpatient CR participation were 0.37 and 0.73, respectively. Although there were statistically significant differences in the hospital-level proportion of CR participation for several hospital factors, CR certification status for reimbursement was the only visually evident factor affecting the distribution of CR participation. Conclusions: The distributions of inpatient and outpatient CR participation by hospitals were suboptimal. Further research is warranted to determine future strategies.
RESUMEN
BACKGROUND: Mechanical circulatory support (MCS) is a common treatment modality for circulatory failure caused by pediatric myocarditis. Despite improvements in treatment strategy, the mortality rate of pediatric patients with myocarditis treated with MCS is still high. Identifying the factors associated with mortality among pediatric patients with myocarditis treated with MCS may help reduce the mortality rate. METHODS: This retrospective cohort study examined the data of patients aged <16â¯years who were admitted to a hospital between July 2010 and March 2018 for myocarditis; the data were collected from the Diagnosis Procedure Combination database, which is a national inpatient database in Japan. RESULTS: During the study period, 105 of the 598 patients with myocarditis were treated with MCS. We excluded seven patients who died within 24â¯h of admission, resulting in 98 eligible patients. The overall in-hospital mortality was 22â¯%. In-hospital mortality was higher among patients aged <2â¯years and those who received cardiopulmonary resuscitation (CPR). Multivariable logistic regression analysis showed significantly higher in-hospital mortality among patients aged <2â¯years old [odds ratio (OR), 6.57; 95â¯% confidence interval (CI), 1.89-22.87] and those who received CPR (OR, 4.70; 95â¯% CI, 1.51-14.63; pâ¯<â¯0.01). CONCLUSION: The in-hospital mortality of pediatric patients with myocarditis treated with MCS was high, particularly of children younger than 2â¯years and those who received CPR.

Objectives: Nursing home terminations have increased worldwide due to rising costs, staffing shortages, and the coronavirus disease pandemic. However, little is known about the impact that business operating systems have on nursing home termination. Methods: This study used the National Long-term Care database, which comprised 7,842 operating nursing homes in January 2018. Nursing home termination was identified when nursing homes discontinued provision of long-term care services to all residents between January 2018 and December 2020. Business operating systems that were reimbursed by the LTC insurance system were the exposure of interest. The logistic regression model for nursing home termination included a series of organizational, internal, and external factors as covariates. Results: From 2018 to 2020, 83 (1.1%) nursing homes were terminated. The proportion of reimbursed nursing homes varied greatly depending on the type of business operating systems. Implementing physical function training and improving working conditions were significantly associated with a lower risk of nursing home termination. Conclusion: Financial incentives to several business operating systems are an effective way to build a sustainable environment for nursing homes to continue to exist.

OBJECTIVES: Generous dental insurance coverage can improve oral health among children. However, most previous studies were from the United States, and the results may not be applicable to countries with universal healthcare systems. The purpose of the present study was to examine the effect of dental subsidy on dental service utilization and oral health among school-aged children. METHODS: An administrative claims database in Kumamoto Prefecture, Japan, between 2014 and 2015 was used for the study. Municipalities in which the upper age limit of qualification for the dental subsidy was either 9 years of age or older were selected. The difference-in-differences approach was used to investigate the impact of subsidy discontinuation on dental care utilization and dental caries prevention. Dental care utilization was measured by number of first visits, number of total visits, and dental care cost per visit. Failure in dental caries prevention was determined by identifying treatment for acute severe dental conditions. RESULTS: During the study period, 1108 eligible children made a total of 6276 visits to the 455 selected dental clinics. Among the dental clinics, 230 (50.5%) were located in municipalities in which the dental subsidy was discontinued when children reached age 10. After adjusting for area income and minimal user charges, there were no significant differences in subsequent dental care utilization (mean ratio 1.01, 95% confidence interval [CI] 0.97-1.04 for first visits; mean ratio 1.01, 95% CI 0.98-1.05 for total visits), acute severe dental conditions (mean ratio 1.06, 95% CI 0.90-1.24) or cost (coefficient 0.7 US dollars; 95%CI -0.2-1.6) during the 12-month period following the policy change. CONCLUSION: The current dental subsidy policy may have limited value for promoting dental care utilization and improving oral health among school-aged children in Japan.

INTRODUCTION: Comparative safety of direct oral anticoagulants vs. warfarin in patients undergoing tooth extraction remains unclear. We compared the incidence of post-extraction bleeding between patients taking warfarin and those taking direct oral anticoagulants (DOACs) using administrative claims data. MATERIALS AND METHODS: We identified outpatients on anticoagulant therapy who underwent permanent tooth extraction between 2015 and 2020 and categorized them into the warfarin and DOAC groups based on medication prescribed within six months prior to tooth extraction. We used the overlap propensity score weighting method to balance the baseline characteristics between the groups and compared the incidence of post-extraction bleeding within seven days after tooth extraction. RESULTS: Among 5253 eligible patients, those in the DOAC group (n = 3696) were older and less frequently prescribed antiplatelets than those in the warfarin group (n = 1557). The distribution of tooth extraction type and number of teeth extracted in a single procedure did not differ between the groups. The unadjusted incidences of post-extraction bleeding in the warfarin and DOAC groups were 35 (2.2 %) and 71 (1.9 %), respectively. Moreover, the overlap weighting analysis showed that the adjusted odds ratio of post-extraction bleeding in the DOAC group in comparison with that in the warfarin group was 0.84 (95 % confidence interval, 0.54-1.31). CONCLUSION: The incidence of post-extraction bleeding in patients taking DOACs was comparable to that in patients taking warfarin. The findings suggest that dentists and physicians should exercise the same degree of caution when extracting teeth in patients on DOACs and those on warfarin in terms of post-extraction bleeding.

OBJECTIVES: Although amoxicillin is the first-line prophylactic drug for impacted mandibular third molar extraction, third-generation cephalosporins are widely prescribed in Japan. The lack of real-world evidence may be one reason for this inappropriate use. We evaluated differences in the incidence of surgical site infection between amoxicillin and third-generation cephalosporins for impacted mandibular third molar extraction. METHODS: Using the JMDC Claims Database, we identified dental visits with fully or horizontally impacted mandibular third molar extraction from April 2015 to March 2020. One-to-one propensity-score matching was conducted between amoxicillin and third-generation cephalosporin groups. The incidence of surgical site infection following extraction was compared in the matched pairs using McNemar's test. RESULTS: We identified 109,266 dental visits, including 39,514 (36.2%) patients who received amoxicillin and 69,752 (63.8%) patients who received third-generation cephalosporins. In the 39,514 matched pairs, the incidence of surgical site infection was 3.5% (n = 1399) for amoxicillin group and 3.7% (n = 1467) for third-generation cephalosporin group (p = 0.003). CONCLUSIONS: Amoxicillin was associated with a lower incidence of surgical site infection after impacted mandibular third molar extraction compared with third-generation cephalosporins. This result supports current guidelines and strengthens the importance of disseminating and implementing antimicrobial resistance control in dentistry.
