Children hospitalised with four common viral diseases showed epidemiological differences but few socio-economic variations.

AIM: This study explored the differences in demographic and socio-economic factors between children hospitalised due to four common viral infections. METHODS: Demographic data were obtained from Statistics Sweden on >3000 children admitted to Astrid Lindgren Children's Hospital in 2009-2014 with rotavirus, influenza, respiratory syncytial virus (RSV) or chickenpox. We compared demographic and socio-economic factors between case groups using logistic regression with rotavirus cases as reference. RESULTS: There were differences in the median age at admission; RSV cases were younger (0.4 years), influenza (2.4 years) and chickenpox cases (2.7 years) older than rotavirus cases (1.2 years). RSV, influenza and chickenpox cases lived in families with more children than rotavirus cases. RSV and influenza cases were more likely to have underlying chronic conditions. Mothers of RSV cases were more likely to be born in Sweden. Further socio-economic differences were not robustly confirmed in sensitivity analyses. CONCLUSION: We found a few differences in demographic factors between children hospitalised with the four common infections, which were mainly explained by the epidemiology and transmission patterns of these infections.

Antimicrobial Use in a Swedish Pediatric Hospital: Results From Eight Point-prevalence Surveys Over a 15-Year Period (2003-2017).

BACKGROUND: Antimicrobial resistance is increasing, and data on antimicrobial use in Swedish children are limited. We evaluated trends in antimicrobial use and attempted to identify targets for improving the quality of antimicrobial prescribing in a tertiary care center. METHODS: One-day hospital-wide point prevalence surveys were conducted 8 times during 2003-2017 at Astrid Lindgren Children's Hospital. Children <17 years old were included. Medical records were evaluated for risk factors, indications for treatment, and antibiotic agents used. RESULTS: Among 946 admitted patients, 36% (336/946) received antimicrobial treatment. The total number of prescriptions increased (P = 0.031), but the proportion of patients treated remained unchanged. The proportion of patients receiving prophylactic treatment increased from 11% to 43% (P = 0.005). The rate of hospital-acquired infections remained unchanged. The primary indication for antimicrobial therapy was sepsis, fever of unknown origin, or fever in neutropenia, followed by intra-abdominal infections and pneumonia. The most frequently used antibiotics were cephalosporins, but consumption decreased, and in 2017 piperacillin-tazobactam was the most frequently used. Antimicrobial use was generally appropriate, although guidelines were often missing. The number of pediatric hospital beds decreased, and the bed occupancy was 71% (101/142) in 2003 and 121% (110/91) in 2017. The patient mix changed toward more patients with underlying risk factors for infectious diseases. CONCLUSIONS: Antimicrobial use changed during the study period, mainly due to increased prophylactic use in at-risk patients. Antimicrobial stewardship programs including infection control interventions and increasing the availability of guidelines may reduce and improve antimicrobial therapy.

Impact on affected families and society of severe rotavirus infections in Swedish children assessed in a prospective cohort study.

BACKGROUND: Few prospective cohort studies have estimated the overall impact of severe rotavirus gastroenteritis (RVGE) leading to hospitalization on families and society. We assessed human and economic resources needed to care for an affected average child aged <5 years in Sweden. METHODS: The study was conducted in Astrid Lindgren Children's Hospital which serves approximately 14% of all Swedish children <5 years of age. All children admitted with acute gastroenteritis in the study period were tested for rotavirus. Health care consumption was collected prospectively and publically available unit costs used to calculate direct costs. Non-medical and indirect costs were collected in interviews with families using a standardized questionnaire during the hospital stay and approximately 14 days post-discharge. RESULTS: 144/206 children (70%) with laboratory-confirmed RVGE were included. The median age was 14 months. The average total cost per hospitalized child was €3894, of which €2169 (56%) was due to direct healthcare-related costs (including Emergency Department visits and in-patient care), €104 (2%) to non-medical direct costs and €1621 (42%) to indirect costs due to productivity loss. Carers of children with severe RVGE were absent from work on average five days per study child: four days during hospitalization of affected child and one day due to gastroenteritis in the carer. CONCLUSIONS: Costs for RVGE are dominated by direct costs which are similar to some other countries in Europe, but indirect costs due to productivity loss are also important, and should be considered in decisions to introduce rotavirus vaccines into national vaccination programmes.
