Implementing evidence-based medicine (EBM) in a busy hospital department is challenging, but when successful, may contribute to quality of care. This paper is a narrative review of the successes and challenges of deliberate implementation of EBM in a paediatric department in a general teaching hospital in Zwolle, the Netherlands. Key elements in this project were providing basic EBM education to the entire team of consultants and nurse practitioners, structurally embedding EBM activities into our weekly schedule and development of local practice guidelines. This deliberate practice of EBM principles has changed the way we treat common paediatric problems. It likely reduced unwarranted practice variation and promoted a reserved attitude towards the use of unnecessary diagnostics, which might improve delivery of effective, cost-conscious care. The project also positively influenced our group culture and learning environment. In accordance with previous reports, lack of time and reluctance to change routines and habits hindered the practice of EBM in our department. In our experience, these barriers can be overcome by promoting a team-wide endorsement of EBM, a willingness to acknowledge uncertainty and by deliberate practice. If these can be achieved, systematic application of EBM principles in a busy hospital department is feasible and worthwhile.

Group A streptococcal (GAS) disease shows increasing incidence worldwide. We characterised children admitted with GAS infection to European hospitals and studied risk factors for severity and disability. This is a prospective, multicentre, cohort study (embedded in EUCLIDS and the Swiss Pediatric Sepsis Study) including 320 children, aged 1 month to 18 years, admitted with GAS infection to 41 hospitals in 6 European countries from 2012 to 2016. Demographic, clinical, microbiological and outcome data were collected. A total of 195 (61%) patients had sepsis. Two hundred thirty-six (74%) patients had GAS detected from a normally sterile site. The most common infection sites were the lower respiratory tract (LRTI) (22%), skin and soft tissue (SSTI) (23%) and bone and joint (19%). Compared to patients not admitted to PICU, patients admitted to PICU more commonly had LRTI (39 vs 8%), infection without a focus (22 vs 8%) and intracranial infection (9 vs 3%); less commonly had SSTI and bone and joint infections ( p < 0.001); and were younger (median 40 (IQR 21–83) vs 56 (IQR 36–85) months, p = 0.01). Six PICU patients (2%) died. Sequelae at discharge from hospital were largely limited to patients admitted to PICU (29 vs 3%, p < 0.001; 12% overall) and included neurodisability, amputation, skin grafts, hearing loss and need for surgery. More patients were recruited in winter and spring ( p < 0.001). Conclusion : In an era of observed marked reduction in vaccine-preventable infections, GAS infection requiring hospital admission is still associated with significant severe disease in younger children, and short- and long-term morbidity. Further advances are required in the prevention and early recognition of GAS disease. What is Known: • Despite temporal and geographical variability, there is an increase of incidence of infection with group A streptococci. However, data on the epidemiology of group A streptococcal infections in European children is limited. What is New: • In a large, prospective cohort of children with community-acquired bacterial infection requiring hospitalisation in Europe, GAS was the most frequent pathogen, with 12% disability at discharge, and 2% mortality in patients with GAS infection. • In children with GAS sepsis, IVIG was used in only 4.6% of patients and clindamycin in 29% of patients.

OBJECTIVES: To determine the prevalence and severity of hospital-acquired infections (HAIs) in children hospitalized for bronchiolitis when patients share a room, irrespective of the causative virus. METHODS: A prospective cohort study during 4 winter seasons (2012–2016) was conducted in a Dutch general pediatric ward including otherwise healthy children &lt;2 years of age hospitalized for bronchiolitis. Patients shared a 1-to-4–bed hospital room irrespective of virological diagnosis. The main outcome measures were HAIs assessed through multiplex polymerase chain reaction and disease severity. RESULTS: HAIs occurred in 28 of 218 included patients (12.8%), most frequently with rhinovirus (17 of 28; 60.7%). In 3 (10.7%) of 28 HAIs, the same virus was identified in roommates. Only 1 patient became cross-infected with respiratory syncytial virus, although this patient never shared a room with a patient infected with respiratory syncytial virus. HAI was not associated with more severe disease. The median length of hospitalization was 3.5 days (interquartile range [IQR] 1–6) compared with 3 days (IQR 2–6; P = .86); the number of PICU admissions was 0% versus 5.3% (P = .21); the median days of oxygen supplementation was 2.5 (IQR 1–4) versus 2 (IQR 1–4; P = .58); the median days of tube feeding was 2 (IQR 0–5) versus 2 (interquartile range: 0–5; P = .77); and the readmission rate was 0% versus 5.8% (P = .19) in patients with and without HAI, respectively. CONCLUSIONS: HAIs among patients with bronchiolitis are common but not associated with more severe disease. Room sharing with appropriate hygiene does not play a relevant role in the transmission of viruses between patients with bronchiolitis, regardless of the viruses involved. On the basis of these findings, we suggest that room sharing of patients with bronchiolitis is safe.
