WHAT'S KNOWN ON THIS SUBJECT: Despite proven health benefits, human papillomavirus (HPV) vaccination rates are among the lowest of all routine immunizations. No previous largescale trial has compared the benefit of automated decision support directed at clinicians, families, or both in any context. WHAT THIS STUDY ADDS:We found that a clinician-focused intervention was most effective for initiating the HPV vaccine series, whereas a family-focused intervention supported completion. Decision support directed at both clinicians and families most effectively promotes HPV vaccine series receipt. abstract OBJECTIVE: To improve human papillomavirus (HPV) vaccination rates, we studied the effectiveness of targeting automated decision support to families, clinicians, or both.METHODS: Twenty-two primary care practices were cluster-randomized to receive a 3-part clinician-focused intervention (education, electronic health record-based alerts, and audit and feedback) or none. Overall, 22 486 girls aged 11 to 17 years due for HPV vaccine dose 1, 2, or 3 were randomly assigned within each practice to receive family-focused decision support with educational telephone calls. Randomization established 4 groups: family-focused, clinician-focused, combined, and no intervention. We measured decision support effectiveness by final vaccination rates and time to vaccine receipt, standardized for covariates and limited to those having received the previous dose for HPV #2 and 3. The 1-year study began in May 2010. RESULTS:Final vaccination rates for HPV #1, 2, and 3 were 16%, 65%, and 63% among controls. The combined intervention increased vaccination rates by 9, 8, and 13 percentage points, respectively. The control group achieved 15% vaccination for HPV #1 and 50% vaccination for HPV #2 and 3 after 318, 178, and 215 days. The combined intervention significantly accelerated vaccination by 151, 68, and 93 days. The clinician-focused intervention was more effective than the familyfocused intervention for HPV #1, but less effective for HPV #2 and 3.CONCLUSIONS: A clinician-focused intervention was most effective for initiating the HPV vaccination series, whereas a family-focused intervention promoted completion. Decision support directed at both clinicians and families most effectively promotes HPV vaccine series receipt.

Background and objectives The prevalence of nephrolithiasis in the United States has increased substantially, but recent changes in incidence with respect to age, sex, and race are not well characterized. This study examined temporal trends in the annual incidence and cumulative risk of nephrolithiasis among children and adults living in South Carolina over a 16-year period.Design, setting, participants, & measurements We performed a population-based, repeated cross-sectional study using the US Census and South Carolina Medical Encounter data, which capture all emergency department visits, surgeries, and admissions in the state. The annual incidence of nephrolithiasis in South Carolina from 1997 to 2012 was estimated, and linear mixed models were used to estimate incidence rate ratios for age, sex, and racial groups. The cumulative risk of nephrolithiasis during childhood and over the lifetime was estimated for males and females in 1997 and 2012.Results Among an at-risk population of 4,625,364 people, 152,925 unique patients received emergency, inpatient, or surgical care for nephrolithiasis. Between 1997 and 2012, the mean annual incidence of nephrolithiasis increased 1% annually from 206 to 239 per 100,000 persons. Among age groups, the greatest increase was observed among 15-19 year olds, in whom incidence increased 26% per 5 years (incidence rate ratio, 1.26; 95% confidence interval, 1.22 to 1.29). Adjusting for age and race, incidence increased 15% per 5 years among females (incidence rate ratio, 1.15; 95% confidence interval, 1.14 to 1.16) but remained stable for males. The incidence among blacks increased 15% more per 5 years compared with whites (incidence rate ratio, 1.15; 95% confidence interval, 1.14 to 1.17). These changes in incidence resulted in doubling of the risk of nephrolithiasis during childhood and a 45% increase in the lifetime risk of nephrolithiasis for women over the study period.Conclusions The incidence of kidney stones has increased among young patients, particularly women, and blacks.

IMPORTANCE Local variation in the transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) across the United States has not been well studied. OBJECTIVE To examine the association of county-level factors with variation in the SARS-CoV-2 reproduction number over time.

WHAT'S KNOWN ON THIS SUBJECT: Tonsillectomy is one of the most commonly performed surgeries in children and is one of the most cumulatively expensive conditions in pediatric hospital care. Little is known about how the quality of tonsillectomy care varies across hospitals. WHAT THIS STUDY ADDS:In a large cohort of low-risk children undergoing same-day tonsillectomy, there was substantial variation in quality measures of process, dexamethasone and antibiotic use, and outcome, revisits to the hospital within the first 30 days after surgery. abstract OBJECTIVE: To describe the quality of care for routine tonsillectomy at US children' s hospitals. METHODS:We conducted a retrospective cohort study of low-risk children undergoing same-day tonsillectomy between 2004 and 2010 at 36 US children' s hospitals that submit data to the Pediatric Health Information System Database. We assessed quality of care by measuring evidence-based processes suggested by national guidelines, perioperative dexamethasone and no antibiotic use, and outcomes, 30-day tonsillectomy-related revisits to hospital. RESULTS:Of 139 715 children who underwent same-day tonsillectomy, 10 868 (7.8%) had a 30-day revisit to hospital. There was significant variability in the administration of dexamethasone (median 76.2%, range 0.3%-98.8%) and antibiotics (median 16.3%, range 2.7%-92.6%) across hospitals. The most common reasons for revisits were bleeding (3.0%) and vomiting and dehydration (2.2%). Older age (10-18 vs 1-3 years) was associated with a greater standardized risk of revisits for bleeding and a lower standardized risk of revisits for vomiting and dehydration. After standardizing for differences in patients and year of surgery, there was significant variability (P , .001) across hospitals in total revisits (median 7.8%, range 3.0%-12.6%), revisits for bleeding (median 3.0%, range 1.0%-8.8%), and revisits for vomiting and dehydration (median 1.9%, range 0.3%-4.4%).CONCLUSIONS: Substantial variation exists in the quality of care for routine tonsillectomy across US children' s hospitals as measured by perioperative dexamethasone and antibiotic use and revisits to hospital. These data on evidence-based processes and relevant patient outcomes should be useful for hospitals' tonsillectomy quality improvement efforts. Pediatrics 2014;133:280-288

IMPORTANCE There are few data on the prevalence or outcome of bystander cardiopulmonary resuscitation (BCPR) in children 18 years and younger. OBJECTIVE To characterize BCPR in pediatric out-of-hospital cardiac arrests (OHCAs). DESIGN, SETTING, AND PARTICIPANTS This analysis of the Cardiac Arrest Registry to Enhance Survival database investigated nontraumatic OHCAs in children 18 years and younger from January 2013 through December 2015.EXPOSURES Bystander CPR, which included conventional CPR and compression-only CPR. MAIN OUTCOMES AND MEASURESOverall survival and neurologically favorable survival, defined as a Cerebral Performance Category score of 1 or 2, at the time of hospital discharge. RESULTSOf the 3900 children younger than 18 years with OHCA, 2317 (59.4%) were infants, 2346 (60.2%) were female, and 3595 (92.2%) had nonshockable rhythms. Bystander CPR was performed on 1814 children (46.5%) and was more common for white children (687 of 1221 [56.3%]) compared with African American children (447 of 1134 [39.4%]) and Hispanic children (197 of 455 [43.3%]) (P < .001). Overall survival and neurologically favorable survival were 11.3% (440 of 3900) and 9.1% (354 of 3900), respectively. On multivariable analysis, BCPR was independently associated with improved overall survival (adjusted proportion,
