Importance: Hospitalizations of infants for bronchiolitis are common and costly. Despite the high incidence and resource burden of bronchiolitis, the mainstay of treatment remains supportive care, which frequently includes nasal suctioning. Objective: To examine the association between suctioning device type and suctioning lapses greater than 4 hours within the first 24 hours after hospital admission on length of stay (LOS) in infants with bronchiolitis. Design: Retrospective cohort study. Data were extracted from the electronic health record. Setting: Main hospital and satellite facility of a large quaternary care children’s hospital from January 10, 2010, through April 30, 2011. Participants: A total of 740 infants aged 2 to 12 months and hospitalized with bronchiolitis. Main Outcome Measure: Hospital LOS. Results: In the multivariable model adjusted for inverse weighting for propensity to receive deep suctioning, increased deep suction as a percentage of suction events was associated with increased LOS with a geometric mean of 1.75 days (95% CI, 1.56–1.95 days) in patients with no deep suction and 2.35 days (2.10–2.62 days) in patients with more than 60% deep suction. An increased number of suctioning lapses was also associated with increased LOS in a dose-dependent manner with a geometric mean of 1.62 days (95% CI, 1.43–1.83 days) in patients with no lapses and 2.64 days (2.30–3.04 days) in patients with 3 or 4 lapses. Conclusions and Relevance: For patients admitted with bronchiolitis, the use of deep suctioning in the first 24 hours after admission and lapses greater than 4 hours between suctioning events were associated with longer LOS.

BACKGROUND AND OBJECTIVES:A 2007 meta-analysis showed probiotics, specifically Lactobacillus rhamnosus GG (LGG), shorten diarrhea from acute gastroenteritis (AGE) by 24 hours and decrease risk of progression beyond 7 days. In 2005, our institution published a guideline recommending consideration of probiotics for patients with AGE, but only 1% of inpatients with AGE were prescribed LGG. The objective of this study was to increase inpatient prescribing of LGG at admission to .90%, for children hospitalized with AGE, within 120 days.METHODS: This quality improvement study included patients aged 2 months to 18 years admitted to general pediatrics with AGE with diarrhea. Diarrhea was defined as looser or $3 stools in the preceding 24 hours. Patients with complex medical conditions or with presumed bacterial gastroenteritis were excluded. Admitting and supervising clinicians were educated on the evidence. We ensured LGG was adequately stocked in our pharmacies and updated an AGE-specific computerized order set to include a default LGG order. Failure identification and mitigation were conducted via daily electronic chart review and e-mail communication. Primary outcome was the percentage of included patients prescribed LGG within 18 hours of admission. Intervention impact was assessed with run charts tracking our primary outcome over time. RESULTS:The prescribing rate increased to 100% within 6 weeks and has been sustained for 7 months. CONCLUSIONS: Keys to success were pharmacy collaboration, use of an electronic medical record for a standardized order set, and rapid identification and mitigation of failures. Rapid implementation of evidence-based practices is possible using improvement science methods.

Many studies have demonstrated a rise in computed tomography (CT) utilization in children's hospitals. However, CT utilization may be declining, perhaps due to awareness of potential hazards of pediatric ionizing radiation, such as increased risk of malignancy. The objective is to assess the trend in CT utilization in hospitalized children at freestanding children's hospitals from 2004 to 2012 and we hypothesize decreases are associated with shifts to alternate imaging modalities.

The quality of evidence from medical research is partially deemed by the hierarchy of study designs. On the lowest level, the hierarchy of study designs begins with animal and translational studies and expert opinion, and then ascends to descriptive case reports or case series, followed by analytic observational designs such as cohort studies, then randomized controlled trials, and finally systematic reviews and meta-analyses as the highest quality evidence. This hierarchy of evidence in the medical literature is a foundational concept for pediatric hospitalists, given its relevance to key steps of evidence-based practice, including efficient literature searches and prioritization of the highest-quality designs for critical appraisal, to address clinical questions. Consideration of the hierarchy of evidence can also aid researchers in designing new studies by helping them determine the next level of evidence needed to improve upon the quality of currently available evidence. Although the concept of the hierarchy of evidence should be taken into consideration for clinical and research purposes, it is important to put this into context of individual study limitations through meticulous critical appraisal of individual articles.
