[PMID: 38588796 DOI: 10.1016/j.jiac.2024.04.005] [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: 12/20/2023] [Revised: 02/26/2024] [Accepted: 04/03/2024] [Indexed: 04/10/2024]
Abstract
BACKGROUND The COVID-19 pandemic posed substantial challenges to healthcare systems. Understanding the responses of pediatric health services is crucial for future pandemic planning and preparedness, yet such data remains limited. METHODS In this retrospective cohort study, we analyzed data from administrative databases developed by Japan Medical Data Center and DeSC Healthcare Inc. The dataset comprised records of 2,612,511 children, totaling 60,224,888 person-months, from January 2020 to May 2022. Multivariate generalized estimation equations were used to examine the incidence rates of COVID-19 and associated health resource use. RESULTS Our analysis revealed that the incidence rates of COVID-19 gradually increased from Wave I (2.2 cases per 100,000 person-months) to Wave V (177.8cases per 100,000 person-months), with a notable elevation during Wave VI (2367.7 cases per 100,000 person-months). While nucleic acid amplification tests were primarily used during Waves I-V, the use of rapid antigen tests markedly increased in Wave VI. The hospitalization rates increased gradually from 0.2 in Wave I to 10.2 events per 100,000 person-months in Wave VI, and the case-hospitalization risk decreased from 14.9% in Wave II to 0.7% in Wave VI. Additionally, we observed decreasing trends in the use of antibiotics (Wave I, 31.8%; Wave VI, 9.0%), whereas antipyretic use rose from Wave I (56.1%) to Wave VI (86.6%). CONCLUSIONS Our study highlighted essential changes in the nationwide pediatric healthcare system's response to the COVID-19 pandemic. These findings provide valuable insights into the future pandemic planning and preparedness.

Nationwide epidemiology and clinical practice patterns of pediatric urinary tract infections: application of multivariate time-series clustering. Pediatr Nephrol 2023; 38:4033-4041. [PMID: 37382710 DOI: 10.1007/s00467-023-06053-2] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/01/2023] [Revised: 06/04/2023] [Accepted: 06/06/2023] [Indexed: 06/30/2023]
Abstract
BACKGROUND The nationwide epidemiology and clinical practice patterns for younger children hospitalized with urinary tract infections (UTIs) were unclear. METHODS We conducted a retrospective observational study consisting of 32,653 children aged < 36 months who were hospitalized with UTIs from 856 medical facilities during fiscal years 2011-2018 using a nationally representative inpatient database in Japan. We investigated the epidemiology of UTIs and changes in clinical practice patterns (e.g., antibiotic use) over 8 years. A machine learning algorithm of multivariate time-series clustering with dynamic time warping was used to classify the hospitals based on antibiotic use for UTIs. RESULTS We observed marked male predominance among children aged < 6 months, slight female predominance among children aged > 12 months, and summer seasonality among children hospitalized with UTIs. Most physicians selected intravenous second- or third-generation cephalosporins as the empiric therapy for treating UTIs, which was switched to oral antibiotics during hospitalizations for 80% of inpatients. Whereas total antibiotic use was constant over the 8 years, broad-spectrum antibiotic use decreased gradually from 5.4 in 2011 to 2.5 days of therapy per 100 patient-days in 2018. The time-series clustering distinctively classified 5 clusters of hospitals based on antibiotic use patterns and identified hospital clusters that preferred to use broad-spectrum antibiotics (e.g., antipseudomonal penicillin and carbapenem). CONCLUSIONS Our study provided novel insight into the epidemiology and practice patterns for pediatric UTIs. Time-series clustering can be useful to identify the hospitals with aberrant practice patterns to further promote antimicrobial stewardship.

Development of a set of quality indicators in paediatric and perinatal care in Japan with a modified Delphi method. BMJ Paediatr Open 2023; 7:e002209. [PMID: 37940343 PMCID: PMC10632888 DOI: 10.1136/bmjpo-2023-002209] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/28/2023] [Accepted: 10/30/2023] [Indexed: 11/10/2023] Open
Abstract
BACKGROUNDS Few paediatric and perinatal quality indicators (QIs) have been developed in the Japanese setting, and the quality of care is not assured or validated. The aim of this study was to develop QIs in paediatric and perinatal care in Japan using an administrative database and confirm the feasibility and applicability of the indicators using a single-site practice test. METHODS We used a RAND-modified Delphi method that integrates evidence review with expert consensus development. QI candidates were generated from clinical practice guidelines (CPGs) available in English or Japanese and existing QIs in nine selected paediatric or perinatal conditions. Consensus building was based on independent panel ratings. The performance of QIs was retrospectively assessed using data from an administrative database at the National Children's Hospital. Data between April 2018 and March 2019 were used, while data between April 2019 and March 2021 were also used for selected condition, considering the small number of patients. Each QI was calculated as follows: number of times the indicator was met/number of participants×100. RESULTS From the literature review conducted between 2010 and 2020, 124 CPGs and 193 existing indicators were identified to generate QI candidates. Through the consensus-building process, 133 QI candidates were assessed and 79 QIs were accepted. The practice test revealed wide variations in the process-level performance of QIs in four categories: patient safety: median 43.9% (IQR 16.7%-85.6%), general paediatrics: median 98.8% (IQR 84.2%-100%), advanced paediatrics: median 94.4% (IQR 46.0%-100%) and advanced obstetrics: median 80.3% (IQR 59.6%-100%). CONCLUSIONS We established 79 QIs for paediatric and perinatal care in Japan using an administrative database that can be applied to hospitals nationwide. The practice test confirmed the measurability of the developed QIs. Benchmarking these QIs will be an attractive approach to improving the quality of care.

Abstract
BACKGROUND Antibiotic use during asthma exacerbations in paediatric patients is not routinely recommended but common practise in out-patient and in-patient settings. Objective of this study was to analyse frequency of antibiotic use during acute severe asthma exacerbations, antibiotic classes utilized and clinical decision-making. METHODS All in-patient admissions over 10 years in a single German Children's University hospital due to acute severe asthma were included in this retrospective analysis. Age, length of stay, oxygen supplementation, treatment, laboratory parameters and chest x-rays of all patients ranging from 1 to 17 years were analysed. RESULTS 580 hospital admissions were included in this study. Overall antibiotic use was high but decreased with age (1-5 years 69,6%, 6-11 years 57,6% and 12-17 years 39,7%, p<0.001). Analysis of antibiotic treatment without clear indication showed a consistently lower treatment rate of 28.3%, with macrolides being the most common antibiotic class. Younger age significantly decreased, whereas, increase of CrP value, use of oxygen supplementation and concomitant fever all significantly increased the odds ratio (OR 0.967; 4.366, 2.472 and 2.011 respectively) of receiving antibiotic treatment without clear indication. CONCLUSION Antibiotic treatment without clear indication during acute severe asthma is common in this German single-centre cohort. Clinical parameters of more severe disease affect clinician's decision to administer antibiotics despite evidence of bacterial infection or improved outcome.
