<p><strong>BACKGROUND AND OBJECTIVES: </strong>Postdischarge treatment of complicated pneumonia includes antibiotics administered intravenously via a peripherally inserted central venous catheter (PICC) or orally. Antibiotics administered via PICC, although effective, may result in serious complications. We compared the effectiveness and treatment-related complications of postdischarge antibiotics delivered by these 2 routes.</p>

<p><strong>METHODS: </strong>This multicenter retrospective cohort study included children ≥2 months and &lt;18 years discharged with complicated pneumonia between 2009 and 2012. The main exposure was the route of postdischarge antibiotic administration, classified as PICC or oral. The primary outcome was treatment failure. Secondary outcomes included PICC complications, adverse drug reactions, other related revisits, and a composite of all 4 outcomes, termed "all related revisits."</p>

<p><strong>RESULTS: </strong>Among 2123 children, 281 (13.2%) received antibiotics via PICC. Treatment failure rates were 3.2% among PICC and 2.6% among oral antibiotic recipients and were not significantly different between the groups in across-hospital-matched analysis (matched odds ratio [OR], 1.26; 95% confidence interval [CI], 0.54 to 2.94). PICC complications occurred in 7.1%. Adverse drug reactions occurred in 0.6% of children; PICC antibiotic recipients had greater odds of adverse drug reaction in across hospital matched analysis (matched OR, 19.1; 95% CI, 4.2 to 87.3). The high rate of PICC complications and differences in adverse drug reactions contributed to higher odds of the composite outcome of all related revisits among PICC antibiotic recipients (matched OR, 4.71; 95% CI, 2.97 to 7.46).</p>

<p><strong>CONCLUSIONS: </strong>Treatment failure rates between PICC and oral antibiotics did not differ. Children with complicated pneumonia should preferentially receive oral antibiotics at discharge when effective oral options are available.</p>

<p><strong>OBJECTIVE: </strong>To compare treatment failure leading to hospital readmission in children with complicated appendicitis who received oral versus intravenous antibiotics after discharge.</p>

<p><strong>BACKGROUND: </strong>Antibiotics are often employed after discharge to prevent treatment failure in children with complicated appendicitis, although existing studies comparing intravenous and oral antibiotics for this purpose are limited.</p>

<p><strong>METHODS: </strong>We identified all patients aged 3 to 18 years undergoing appendectomy for complicated appendicitis, who received postdischarge antibiotics at 35 childrens hospitals from 2009 to 2012. Discharge codes were used to identify study subjects from the Pediatric Health Information System database, and chart review confirmed eligibility, treatment assignment, and outcomes. Exposure status was based on outpatient antibiotic therapy, and analysis used optimal and full matching methods to adjust for demographic and clinical characteristics. Treatment failure (defined as an organ-space infection) requiring inpatient readmission was the primary outcome. Secondary outcomes included revisits from any cause to either the inpatient or emergency department setting.</p>

<p><strong>RESULTS: </strong>In all, 4579 patients were included (median: 99/hospital), and utilization of intravenous antibiotics after discharge ranged from 0% to 91.7% across hospitals. In the matched analysis, the rate of treatment failure was significantly higher for the intravenous group than the oral group [odds ratio (OR) 1.74, 95% confidence interval (CI) 1.05-2.88; risk difference: 4.0%, 95% CI 0.4-7.6%], as was the rate of all-cause revisits (OR 2.11, 95% CI 1.44-3.11; risk difference: 9.4%, 95% CI 4.7-14.2%). The rate of peripherally inserted central catheter line complications was 3.2% in the intravenous group, and drug reactions were rare in both groups (intravenous: 0.7%, oral: 0.5%).</p>

<p><strong>CONCLUSIONS: </strong>Compared with oral antibiotics, use of intravenous antibiotics after discharge in children with complicated appendicitis was associated with higher rates of both treatment failure and all-cause hospital revisits.</p>

<p><strong>BACKGROUND AND OBJECTIVES: </strong>Appendicitis guidelines recommend either narrower- or extended-spectrum antibiotics for treatment of complicated appendicitis. The goal of this study was to compare the effectiveness of extended-spectrum versus narrower-spectrum antibiotics for children with appendicitis.</p>

<p><strong>METHODS: </strong>We performed a retrospective cohort study of children aged 3 to 18 years discharged between 2011 and 2013 from 23 freestanding children's hospitals with an appendicitis diagnosis and appendectomy performed. Subjects were classified as having complicated appendicitis if they had a postoperative length of stay ≥3 days, a central venous catheter placed, major or severe illness classification, or ICU admission. The exposure of interest was receipt of systemic extended-spectrum antibiotics (piperacillin ± tazobactam, ticarcillin ± clavulanate, ceftazidime, cefepime, or a carbapenem) on the day of appendectomy or the day after. The primary outcome was 30-day readmission for wound infection or repeat abdominal surgery. Multivariable logistic regression, propensity score weighting, and subgroup analyses were used to control for confounding by indication.</p>

<p><strong>RESULTS: </strong>Of 24 984 patients, 17 654 (70.7%) had uncomplicated appendicitis and 7330 (29.3%) had complicated appendicitis. Overall, 664 (2.7%) patients experienced the primary outcome, 1.1% among uncomplicated cases and 6.4% among complicated cases (P &lt; .001). Extended-spectrum antibiotic exposure was significantly associated with the primary outcome in complicated (adjusted odds ratio, 1.43 [95% confidence interval, 1.06 to 1.93]), but not uncomplicated, (adjusted odds ratio, 1.32 [95% confidence interval, 0.88 to 1.98]) appendicitis. These odds ratios remained consistent across additional analyses.</p>

<p><strong>CONCLUSIONS: </strong>Extended-spectrum antibiotics seem to offer no advantage over narrower-spectrum agents for children with surgically managed acute uncomplicated or complicated appendicitis.</p>

<p><strong>BACKGROUND: </strong>More than 80% of surgical inpatients at US children's hospitals receive antibiotics, accounting for &gt;40% of all inpatient pediatric antibiotic use. We aimed to examine the collective pool of all systemic antibiotics prescribed to children hospitalized for surgical conditions and identify common surgical conditions with highly variable and potentially unnecessary antibiotic use, because these conditions may represent antimicrobial stewardship priorities.</p>

<p><strong>METHODS: </strong>We conducted a retrospective cross-sectional study of surgical inpatients discharged in 2012 at 37 freestanding children's hospitals. We captured all systemic antibiotic use as days of therapy (DOT), and we reported surgical conditions by frequency and contribution to overall antibiotic use. We used multivariable logistic and Poisson regression with marginal standardization to estimate (1) the standardized proportion and (2) DOT of condition-specific targeted antibiotic use among top surgical condition patients.</p>

<p><strong>RESULTS: </strong>Among 151 345 surgical inpatients, 82.9% received antimicrobials for a median 2 DOT per subject (interquartile range, 1-5; range, 1-958). The most commonly received antibiotics were cefazolin (16.7% of all DOT), vancomycin (12.5%), and piperacillin/tazobactam (6.9%). The top 10 conditions contributing most to antibiotic use accounted for 51.3% of all antibiotic use. Among these, adjusted use of postoperative and perioperative vancomycin varied across hospitals among craniotomy and cardiothoracic surgery subjects (all P &lt; .001); adjusted use of broad-spectrum antipseudomonal agents varied across hospitals among gastrointestinal surgery subjects (all P &lt; .001).</p>

<p><strong>CONCLUSIONS: </strong>Use of (1) vancomycin for pediatric cardiothoracic and neurosurgical patients and (2) broad-spectrum antipseudomonal agents for gastrointestinal surgery patients represent potentially high-yield targets for stewardship efforts to reduce unnecessary antimicrobial use.</p>

Comparative effectiveness of intravenous vs oral antibiotics for postdischarge treatment of acute osteomyelitis in children.

2168-6211

<p><strong>IMPORTANCE: </strong>Postdischarge treatment of acute osteomyelitis in children requires weeks of antibiotic therapy, which can be administered orally or intravenously via a peripherally inserted central catheter (PICC). The catheters carry a risk for serious complications, but limited evidence exists on the effectiveness of oral therapy.</p>

<p><strong>OBJECTIVE: </strong>To compare the effectiveness and adverse outcomes of postdischarge antibiotic therapy administered via the PICC or the oral route.</p>

<p><strong>DESIGN, SETTING, AND PARTICIPANTS: </strong>We performed a retrospective cohort study comparing PICC and oral therapy for the treatment of acute osteomyelitis. Among children hospitalized from January 1, 2009, through December 31, 2012, at 36 participating children's hospitals, we used discharge codes to identify potentially eligible participants. Results of medical record review confirmed eligibility and defined treatment group allocation and study outcomes. We used within- and across-hospital propensity score-based full matching to adjust for confounding by indication.</p>

<p><strong>INTERVENTIONS: </strong>Postdischarge administration of antibiotics via the PICC or the oral route.</p>

<p><strong>MAIN OUTCOMES AND MEASURES: </strong>The primary outcome was treatment failure. Secondary outcomes included adverse drug reaction, PICC line complication, and a composite of all 3 end points.</p>

<p><strong>RESULTS: </strong>Among 2060 children and adolescents (hereinafter referred to as children) with osteomyelitis, 1005 received oral antibiotics at discharge, whereas 1055 received PICC-administered antibiotics. The proportion of children treated via the PICC route varied across hospitals from 0 to 100%. In the across-hospital (risk difference, 0.3% [95% CI, -0.1% to 2.5%]) and within-hospital (risk difference, 0.6% [95% CI, -0.2% to 3.0%]) matched analyses, children treated with antibiotics via the oral route (reference group) did not experience more treatment failures than those treated with antibiotics via the PICC route. Rates of adverse drug reaction were low (&lt;4% in both groups) but slightly greater in the PICC group in across-hospital (risk difference, 1.7% [95% CI, 0.1%-3.3%]) and within-hospital (risk difference, 2.1% [95% CI, 0.3%-3.8%]) matched analyses. Among the children in the PICC group, 158 (15.0%) had a PICC complication that required an emergency department visit (n = 96), a rehospitalization (n = 38), or both (n = 24). As a result, the PICC group had a much higher risk of requiring a return visit to the emergency department or for hospitalization for any adverse outcome in across-hospital (risk difference, 14.6% [95% CI, 11.3%-17.9%]) and within-hospital (risk difference, 14.0% [95% CI, 10.5%-17.6%]) matched analyses.</p>

<p><strong>CONCLUSIONS AND RELEVANCE: </strong>Given the magnitude and seriousness of PICC complications, clinicians should reconsider the practice of treating otherwise healthy children with acute osteomyelitis with prolonged intravenous antibiotics after hospital discharge when an equally effective oral alternative exists.</p>
