Abstract
OBJECTIVE To evaluate the status of lupus nephritis treatment particularly regarding the need for intensification of treatment in Japan from 2010 to 2019 using a large-scale claims database. METHODS This descriptive study included adult lupus nephritis patients who were administered glucocorticoid equivalent to ≥15 mg prednisolone as the initial dose. After summarizing patient characteristics, we assessed the rate of treatment intensification using the Kaplan-Meier method among six groups based on initial dose of glucocorticoid. RESULTS We identified 403 patients (mean age, 42.7 years; 68.5% women) with the median initial glucocorticoid dose of 30 mg/day prednisolone equivalent. We observed 56 treatment intensifications; the incidence rate was 71.3 per 1,000 person-years (95% confidence interval: 52.6-90.0). The rate in higher glucocorticoid dose groups was higher than that in lower glucocorticoid dose groups. CONCLUSIONS We found that the rate of treatment intensification was higher in the high-dose glucocorticoid groups than in the low-dose glucocorticoid groups. Further studies are needed to clarify the relationship between the initial dose of glucocorticoids and the prognosis of lupus nephritis patients.

Abstract
Introduction Tracheostomy is commonly performed for upper airway obstruction, prolonged mechanical ventilation and tracheo-bronchial toileting. Pediatric tracheostomy differs from adult tracheostomy in terms of surgical procedure, post-operative care and recovery. The tracheostomized patients may either be decannulated, discharged with tube-in-situ or the patient may expire. The aim of this study was to find out the prevalence of tracheostomy in patients admitted to the Pediatric intensive care unit of a tertiary care centre. Methods A descriptive cross-sectional study was performed among children admitted to the Pediatric intensive care unit of a tertiary care centre from 1 May 2017 to 31 August 2022 after obtaining ethical approval from the Institutional Review Committee. A convenience sampling method was used. The point estimate was calculated at 95% Confidence Interval. Results Among 1472 patients, tracheostomy was done in 65 (4.41%) (3.37-5.47, 95% Confidence Interval). A total of 33 (50.76%) underwent tracheostomy for prolonged ventilation whereas 32 (49.23%) were tracheostomized for airway obstruction. Among them, 41 (63.07%) patients were successfully decannulated, 9 (13.84%) were discharged with tracheostomy tubes in situ whereas 15 (23.07%) patients deceased. The most common complication was tracheostomy tube blockage reported in 5 (7.69%). Conclusions The prevalence of tracheostomy among the children of the pediatric intensive care unit was found to be lower than in other studies. Keywords mechanical ventilation; complication; pediatric; tracheostomy.

A retrospective cohort study using a nationwide claims database. Acta Diabetol 2023; 60:1541-1549. [PMID: 37421440 DOI: 10.1007/s00592-023-02147-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/19/2023] [Accepted: 06/25/2023] [Indexed: 07/10/2023]
Abstract
AIM To examine the effect of nutritional guidance (NG) provided by a registered dietitian under the direction of a physician on the development of subsequent cardiovascular events in patients with early-stage type 2 diabetes mellitus (T2DM). MATERIALS AND METHODS This retrospective cohort study used the JMDC claims database to explore patients aged 18 years or older who first met the diagnostic criteria for T2DM at a health checkup between January 2011 and January 2019. The last day of the observation period was set for 28 February, 2021. Exposure was defined as receiving NG within 180 days of diagnosis of T2DM. The primary outcome was a composite endpoint of coronary artery disease (CAD) and cerebrovascular disease, and the secondary outcomes were each event, and time to event was compared. The propensity score weighting method was used for adjusting the distribution of confounding variables. Cox regression was conducted to estimate hazard ratios (HRs) and 95% confidence intervals (CIs). RESULTS Overall, 31,378 patients met the eligibility criteria at an annual health checkup. 9.6% received NG (n = 3013). Patients who attended ≥ 1 NG after diagnosis had significantly reduced risk of cardiovascular composite (adjusted HR 0.75, 95% CI 0.58-0.97) and cerebrovascular disease (adjusted HR 0.65, 95% CI 0.47-0.90) during approximately 3.3 years of follow-up. In contrast, no difference was observed for CAD. CONCLUSIONS Receiving NG in early-stage diabetes may reduce the incidence of cardiovascular events, especially cerebrovascular events.

Abstract
BACKGROUND Foreign body aspiration into the trachea is a common occurrence in children. While most foreign bodies in the airways can be removed using rigid tracheoscopy, there are instances where tracheostomy or tracheotomy is needed. This article presents a series of cases in which tracheostomy was necessary to remove foreign bodies, and summarizes the relevant experiences and lessons learned. METHODS We reviewed a total of 7 cases in which tracheostomy and rigid tracheoscopy were combined for foreign body removal out of a larger cohort of 1559 cases at Shenzhen Children's Hospital in Guangdong, China over a 20-year period. RESULTS The combined use of tracheostomy and rigid tracheoscopy resulted in successful removal of foreign bodies in all 7 patients reviewed in this study. Six patients developed complications of tracheotomy, mainly including mediastinal emphysema (5/7), subcutaneous emphysema (3/7), and pneumothorax (1/7). Tracheotomy was temporary in all patients. CONCLUSION In cases where a foreign body in the trachea is too large or has irregular, sharp edges, is embedded in submucosal tissues with edema, cannot be passed smoothly through the vocal cords, or local endoscopic facilities are inadequate, a tracheotomy may be necessary. However, this approach should be used with caution, and close collaboration with anesthesiologists and careful management of intraoperative emergencies are crucial for improving the success rate of the procedure. Additionally, the complications should be noted, paying particular attention to early complications such as pneumothorax, pneumomediastinum, and bleeding.

Abstract
STUDY DESIGN Retrospective cohort study. OBJECTIVE The aim of this study was to determine predictors associated with the needfor cervical ossification of the posterior longitudinal ligament (cOPLL) surgery amongindividuals with cOPLL. SUMMARY OF BACKGROUND DATA cOPLL is a spinal disorder caused by ectopic ossification of the posterior longitudinal ligament. However, factors associated with a higher rate of surgery to treat the neurological symptoms of cOPLL are poorly understood. MATERIALS AND METHODS This retrospective population-based cohort study using a commercial administrative claims database from JMDC Inc. (Tokyo, Japan) enrolled patients newly diagnosed with cOPLL from April 2005 to October 2020 and followed to April 2021. A total of 1506 cOPLL patients aged 18 years or older with no history of cervical spine surgery and with a record of metabolic profiles obtained at general health checkups were included. Cox proportional hazards regression models identified patient characteristics and comorbidities associated with cOPLL surgery. RESULTS Of 1506 patients with cOPLL with a median of 1.8 years of follow-up after initial cOPLL diagnosis, 439 (29.2%) received cOPLL surgery. The 1-year cumulative incidence (95% CI) was 26.0% (23.7-28.2). In multivariable Cox proportional regression analysis, male (hazard ratio: 1.68; 95% CI: 1.26-2.24; P < 0.001) and obesity (body mass index: ≥25) (hazard ratio: 1.45; 95% CI: 1.10-1.89; P = 0.007) were associated with an increased risk of cOPLL surgery. CONCLUSIONS In this large claims-based study of adults newly diagnosed with cOPLL, males and obesity were associated with a higher risk of cOPLL surgery. These findings may help clinicians to predict the future course of cOPLL in patients, although further research is needed to elucidate the biological role of these progression-associated factors.

Abstract
OBJECTIVES The aims of this study were to evaluate the association between hypouricemia and cardiometabolic diseases, such as hypertension, dyslipidemia, and reduced kidney function, and to explore the sex-specific optimal range for serum uric acid (sUA) associated with the lowest risk for these diseases. METHODS In this cross-sectional study, we identified individuals with sUA data between April 2018 and March 2019 and recorded the frequency of cardiometabolic comorbidities according to sUA. Univariable and multivariable logistic regression analyses were performed for the overall population and after classifying by sex to assess the association between sUA and cardiometabolic comorbidities. RESULTS Among 796,508 individuals, a J-shaped association was observed between the sUA level and cardiometabolic diseases in the overall population. The adjusted odds ratios (95% confidence interval) for hypertension, dyslipidemia, and reduced renal function in individuals with sUA ≤1.0 mg/dL compared with those with sUA ranging between 2.1 and 3.0 mg/dL were 1.38 (1.13-1.69), 1.52 (1.30-1.78), and 2.17 (1.47-3.20), respectively. A J-shaped association between sUA and hypertension was observed only in women. The optimal range of sUA associated with the lowest risk for hypertension was assumed to be <6 mg/dL in men and 1-4 mg/dL in women. A J-shaped association between the sUA and dyslipidemia and reduced renal function was observed in both men and women. The optimal range of sUA for dyslipidemia and reduced renal function was approximately 2-5 mg/dL in men and 1-4 mg/dL in women. CONCLUSIONS Excess and extremely low uric acid levels may be related to an increased cardiometabolic risk.

Abstract
BACKGROUND Estrogen therapy (ET) plays a key role in maintaining the post-surgical quality of life of patients with endometrial cancer. This study investigated the reality of the use of ET after endometrial cancer surgery in Japan. METHODS Using a healthcare database in Japan, patients who underwent surgery for endometrial cancer between the ages of 40 and 59 years from January 2006 to March 2021 were included. The cumulative prescriptions of ET after endometrial cancer surgeries in patients who had received chemotherapy or radiation therapy (adj-group) and those who did not (non-adj-group) was estimated using the Kaplan-Meier method. RESULTS Of the 1475 patients, 115 received ET, among whom transdermal estradiol was initiated in 100 (87.0%) individuals. The cumulative proportions of ET prescription 24 months after surgery [95% confidence intervals (CIs)] were 0.088 [0.072, 0.11] in the non-adj-group and 0.058 [0.040, 0.084] in the adj-group. The cumulative proportion [95% CI] of women who received ET at 24 months after surgeries decreased with increasing age, ranging from 0.29 [0.21, 0.38] in the 40‒44 years old to 0.009 [0.002, 0.034] in the 55‒59 years old women in the non-adj-group and from 0.17 [0.094, 0.31] in the 40‒44 years old to 0 in the 55‒59 years old women in the adj-group. CONCLUSION The present study shows that ET after endometrial cancer surgery may be underused, even in women who underwent surgery between 40 and 44 years of age and without adjuvant therapy.

Reoperation Rates of Microendoscopic Discectomy Compared With Conventional Open Lumbar Discectomy: A Large-database Study. Clin Orthop Relat Res 2023; 481:145-154. [PMID: 35838602 PMCID: PMC9750527 DOI: 10.1097/corr.0000000000002322] [Citation(s) in RCA: 7] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/19/2022] [Accepted: 06/23/2022] [Indexed: 01/31/2023]
Abstract
BACKGROUND Microendoscopic discectomy for lumbar disc herniation has been shown to be as effective as traditional microdiscectomy or open discectomy in terms of clinical outcomes such as pain relief, and it is less invasive. Nevertheless, the reoperation rate for microendoscopic discectomy compared with microdiscectomy or open discectomy remains unclear, possibly due to difficulties in conducting follow-up of sufficient duration and in obtaining information about reoperation in other facilities. QUESTIONS/PURPOSES (1) What is the rate of reoperation after microendoscopic discectomy for primary lumbar disc herniation on a large scale at a median of 4 years postoperatively? (2) Is there any difference in revision rate at a median of 4 years and within 90 days postoperatively based on surgical method? METHODS We conducted a retrospective, comparative study of adult patients who underwent microendoscopic discectomy or microdiscectomy or open discectomy for lumbar disc herniation from April 2008 to October 2017 and who were followed until October 2020 using a commercially available administrative claims database from JMDC Inc. This claims-based database provided information on individual patients collected across multiple hospitals, which improved the accuracy of postoperative reoperation rates. We included 3961 patients who received microendoscopic discectomy or microdiscectomy or open discectomy between April 2008 and October 2017 in the JMDC claims database. After applying exclusion criteria, 50% (1968 of 3961) of patients were eligible for this study. Propensity score-weighted analyses were conducted in 646 patients in the microendoscopic discectomy group and in 1322 in the microdiscectomy or open discectomy group, with a median (IQR) of 4 years (3 to 6) of follow-up in both groups. Mean patient age was 42 ± 12 years in the microendoscopic discectomy group and 43 ± 12 years in the microdiscectomy or open discectomy group. Males accounted for 78% (505 of 646) of patients in the microendoscopic discectomy group and 79% (1050 of 1322) of patients in microdiscectomy or open discectomy group. The proportion of patients with diabetes mellitus in the microendoscopic discectomy group (10% [64 of 646]) was less than in the microdiscectomy or open discectomy group (15% [195 of 1322]). The primary outcome was Kaplan-Meier survivorship free from any type of additional lumbar spine surgery at a median of 4 years after the index surgery. The secondary outcome was survival probability using the Kaplan-Meier method with endpoints of any type of reoperation within 90 days after the index surgery. To determine which procedure had the higher revision rate, we conducted propensity score overlap weighting analysis, which controlled for potential confounding variables such as age, sex, comorbidities, and type of hospital as well as Cox proportional hazard models to estimate HRs and 95% confidence intervals (CIs). RESULTS The 5-year cumulative reoperation rate was 12% (95% CI 9% to 15%) in the microendoscopic discectomy group and 7% (95% CI 6% to 9%) in the microdiscectomy or open discectomy group. After controlling for potentially confounding variables like age, sex, and diabetes mellitus, the microendoscopic discectomy group had a higher reoperation risk than the microdiscectomy or open discectomy group (weighted HR 1.57 [95% CI 1.14 to 2.16]; p = 0.004). Within 90 days of the index surgery, after controlling for potentially confounding variables like age, sex, and diabetes mellitus, we found no difference between the microendoscopic discectomy group and microdiscectomy or open discectomy group in terms of risk of reoperation (weighted HR 1.38 [95% CI 0.68 to 2.79]; p = 0.38). CONCLUSION Given the higher reoperation risk with microendoscopic discectomy compared with microdiscectomy or open discectomy at a median of 4 years of follow-up, surgeons should select microdiscectomy or open discectomy, despite the current popularity of microendoscopic discectomy. The revision risk of microendoscopic discectomy compared with microdiscectomy or open discectomy in the long term remains unclear. Future large, prospective, multicenter cohort studies with long-term follow-up are needed to confirm the association between microendoscopic discectomy and risk of reoperation.

Abstract
Despite the exponential increase in the use of tracheostomy worldwide, rates of tracheostomy decannulation are unknown. We conducted a retrospective cohort study to investigate tracheostomy decannulation rates among adult patients over a two-year period and explored factors associated with prolonged tracheostomy. A health insurance claims database including 3,758,210 people in Japan was used. The primary outcome was time to decannulation. Assessed patient and hospital factors included age, sex, emergency endotracheal intubation, disease, and hospital size. A total of 917 patients underwent tracheostomy, and 752 met the eligibility criteria. Decannulation rates were 40.8% (95% confidence interval 36.8-44.9) at 3 months, 63.9% (58.4-69.0) at 12 months, and 65.0% (59.2-70.3) at 24 months. Hazard ratios of patient and hospital factors for tracheostomy decannulation were 0.44 for age (65-74 years) (95% confidence interval 0.28-0.68), 0.81 (0.63-1.05) for female sex, and 0.59 (0.45-0.76) for emergency endotracheal intubation. Cerebrovascular disease, head injuries, and cardiac arrest had lower hazard ratios compared to other diseases. Decannulation rates among adult patients in Japan increased rapidly up to 3 months after tracheostomy, reaching a plateau after 12 months. Older age, female sex, emergency endotracheal intubation, cerebrovascular disease, head injuries, and cardiac arrest were associated with prolonged tracheostomy.

Abstract
Objective:To disscuss the changes in indications, surgical opportunity and post-operative management of pediatric tracheotomy. Methods:Retrospective cohort study of pediatric patients undergoing tracheostomy between January 2016 and December 2020 at Children's Hospital of Fudan University. Ninety-five patients were divided into four groups according to their primary indication. Group A: neuromuscular disease(n=36, 37.9%), Group B: congenital abnormality(n=30, 31.6%), Group C: accidental injury(n=15, 15.8%), Group D: tumor(n=14, 14.7%). Results:By the comparison between four groups, children in group A had higher incidence of Severe pneumonia(47.2%), higher usage of mechanical ventilation(97.2%), longer hospitalization days(=84.9 days) and higher rate of Ventilator dependence(66.7%); children in group B had higher rate of emergency surgery(4.2%), lower age(median age 2 months) and lower usage of mechanical ventilation(30.0%); Mortality of the children in group D was the highest(42.9%). In the recent five years, we saw a increasing tendency in the proportion of group A(28.6%, 35.0%, 38.5%, 44.4%, 43.5%), and a decreasing tendency of group B(57.1%, 30.0%, 38.5%, 33.3%, 21.7%). On discharge, 50.5% of children(48 of 95)spontaneously breathe with the tracheos tomy in situ, 29.5% of children(28 of 95)had ventilator-dependence, tracheostomy decannulation was successful in 6.3% of children (6 of 95) and all-cause mortality was 13.7% (13 of 95). Conclusion:Most paediatric tracheotomies were performed due to chronic underlying diseases. Pediatric tracheostomy should be considered as a long-term intervention in many children. Earlier tracheotomy can shorten the duration of post-tracheotomy mechanical ventilation in several conditions.

Abstract
OBJECTIVE To evaluate current practices of tracheostomy in children regarding the ideal timing of tracheostomy placement, complications, indications, mortality, and success in decannulation. SOURCE OF DATA The authors searched PubMed, Embase, Cochrane Library, Google Scholar, and complemented by manual search. The guidelines of PRISMA and MOOSE were applied. The quality of the included studies was evaluated with the Newcastle-Ottawa Scale. Information extracted included patients' characteristics, outcomes, time to tracheostomy, and associated complications. Odds ratios (ORs) with 95% CIs were computed using the Mantel-Haenszel method. SYNTHESIS OF DATA Sixty-six articles were included in the qualitative analysis, and 8 were included in the meta-analysis about timing for tracheostomy placement. The risk ratio for "death in hospital outcome" did not show any benefit from performing a tracheostomy before or after 14 days of mechanical ventilation (p = 0.49). The early tracheostomy before 14 days had a great impact on the days of mechanical ventilation (-26 days in mean difference, p < 0.00001). The authors also found a great reduction in hospital length of stay (-31.4 days, p < 0.008). For the days in PICU, the mean reduction was of 14.7 days (p < 0.007). CONCLUSIONS The meta-analysis suggests that tracheostomy performed in the first 14 days of ventilation can reduce the time spent on the ventilator, and the length of stay in the hospital, with no effect on mortality. The decision to perform a tracheostomy early or late may be more dependent on the baseline disease than on the time spent on ventilation .

Abstract
OBJECTIVE Tracheostomy in children is a surgical procedure with considerable morbidity and mortality. However, there is still a lack of population-based survey in pediatric tracheostomy. This study analyses population-based data in pediatric tracheostomy among different ages in Taiwan. METHODS This study used National Health Insurance Research Database in Taiwan. All children (aged <18 years) who underwent tracheostomy during 1997-2016 were identified. We retrieved data regarding baseline characteristics, perioperative care, and mortality associated with pediatric tracheostomy, and compared differences in variables between different age groups. RESULTS We observed that 2300 children received tracheostomy (mean age, 8.7 years; 64% boys). Regarding the age group distribution of the patients, 585 (25.4%) were infants (<1 year), 227 (9.9%) were toddlers (1-3 years), 175 (7.6%) were preschool-aged children (3-6 years), 317 (13.8%) were school-aged children (6-12 years), and 996 (43.3%) were adolescents (12-18 years). Surgical indications included pulmonary disorders (64.9%), neurological disorders (38.4%), trauma (32.3%), head injury (25.2%), and congenital anomalies (21.5%). Of these patients, 94.9% required intensive care unit (ICU) care, with the mean length of ICU stay being 63.8 days. The mean length of hospital stay was 74.5 days. The overall mortality at the last follow-up was 43.96% (1011/2300), and the tracheostomy related mortality at the last follow-up was 1.43% (33/2300). Compared with adolescents, infants more commonly underwent tracheostomy in the northern area (66.7% vs 37.2%, P < .001), more commonly received tracheostomy indicated by congenital anomalies (53.7 vs 4.6%, P < .001), had longer ICU stays, had longer hospital stays (100.7 vs 57.5 days, P < .001), and had a higher 5-year mortality rate (42.4 vs 29.6%, P < .001). Multivariable logistic and Cox regression models revealed that young age was associated with an increased risk of prolonged hospital stay and long-term mortality, respectively. CONCLUSIONS This study elaborates the epidemiology of pediatric tracheostomy in different age groups.

Abstract
Hospital-based registry data, including patients' information collected by academic societies or government based research groups, were previously used for clinical research in Japan. Now, real-world data routinely obtained in healthcare settings are being used in clinical epidemiology and pharmacoepidemiology. Real-world data include a database of claims originating from health insurance associations for reimbursement of medical fees, diagnosis procedure combinations databases for acute inpatient care in hospitals, a drug prescription database, and electronic medical records, including patients' medical information obtained by doctors, derived from electronic records of hospitals. In the past ten years, much evidence of clinical epidemiology and pharmacoepidemiology studies using real-world data has been accumulated. The purpose of this review was to introduce clinical epidemiology and pharmacoepidemiology approaches and studies using real-world data in Japan.

Abstract
BACKGROUND We aimed to update information on the prevalence of chronic kidney disease (CKD) in Japan. We also explored whether CKD was properly recognized and managed. METHODS We used data from annual health checkups in 2017, compiling records for 5 million persons. These included laboratory results and were linked to healthcare utilization records via personal identifiers. CKD was defined as an estimated glomerular filtration rate <60 mL/min/1.73 m2. The prevalence was compared with that in 2005. Healthcare utilization, including laboratory tests, disease coding and medication for comorbid diabetes mellitus (DM) and hypertension (HT), was used as an indicator for the recognition and management of CKD. RESULTS Of the 761 565 records [median age 46 years (interquartile range 50-62)], CKD was found in 50 091 persons; the crude and age-adjusted prevalences were 63.1 and 71.8 per 1000 persons, respectively. CKD prevalence was significantly higher in 2017 than in 2005, with an increase of 14.1 per 1000 persons. Among persons with CKD, >95% sought medical services and 64.6% received laboratory tests within 180 days of the checkup. However, the diagnostic code suggestive of CKD was recorded in only 23.2% of patients and prescriptions for DM and HT were found in 31.2% (1590/5096) and 36.7% (8081/22 019) of comorbid persons, respectively. CONCLUSIONS The prevalence of CKD in Japan has increased over the past decade. However, recognition of CKD is likely suboptimal and there is room to improve the management of comorbid DM and HT.

First-line antibiotic prescription patterns for acute otitis media in children: A descriptive study using Japanese claims data (2014-2018). J Infect Chemother 2021; 27:1300-1305. [PMID: 33992520 DOI: 10.1016/j.jiac.2021.04.015] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/27/2020] [Revised: 04/06/2021] [Accepted: 04/14/2021] [Indexed: 11/25/2022]
Abstract
INTRODUCTION Acute otitis media is a highly prevalent disease in children. Although guidelines in many countries recommend amoxicillin as the first-line treatment for acute otitis media, the prescribing pattern in Japan is not clear. Our objective was to clarify the amoxicillin prescriptions as first-line antibiotics for acute otitis media and factors associated with amoxicillin prescriptions. Also, changes in amoxicillin prescriptions during the study period by medical facilities were investigated. METHODS Using an administrative claims database, we included new episodes of acute otitis media prescribed antibiotics in children under seven years of age between 2014 and 2018. The proportion of amoxicillin prescription was described. Using multivariate logistic regression analysis, factors associated with amoxicillin prescription were evaluated. Rate differences were calculated to describe changes in amoxicillin prescription by medical facilities. RESULTS 207,213 episodes in 149,929 patients were identified. Amoxicillin prescription was 24.0% and increased over the study period (P for trend <0.001). Characteristics of medical facilities were associated with amoxicillin prescriptions, and hospitals were more likely to prescribe amoxicillin (adjusted odds ratio: 1.71, 95% confidence intervals: 1.63 to 1.79). Compared to 2014, the range of increase in amoxicillin prescription in 2018 was greater in hospitals (14.9%) and pediatric clinics (10.5%) than in otolaryngology clinics (5.9%) and other specialty clinics (6.0%). CONCLUSIONS During the study period, amoxicillin prescriptions had increased compared to 2014, but the proportion was still low. Clinics prescribed less amoxicillin than hospitals, and the range of increase was small. Our results suggested that some interventions focused on clinics are needed.
