Patterns of rotavirus vaccine uptake and use in privately-insured US infants, 2006-2010.

ABSTRACT: Rotavirus vaccines are highly effective at preventing gastroenteritis in young children and are now universally recommended for infants in the US. We studied patterns of use of rotavirus vaccines among US infants with commercial insurance. We identified a large cohort of infants in the MarketScan Research Databases, 2006-2010. The analysis was restricted to infants residing in states without state-funded rotavirus vaccination programs. We computed summary statistics and used multivariable regression to assess the association between patient-, provider-, and ecologic-level variables of rotavirus vaccine receipt and series completion. Approximately 69% of 594,117 eligible infants received at least one dose of rotavirus vaccine from 2006-2010. Most infants received the rotavirus vaccines at the recommended ages, but more infants completed the series for monovalent rotavirus vaccine than pentavalent rotavirus vaccine or a mix of the vaccines (87% versus 79% versus 73%, P<0.001). In multivariable analyses, the strongest predictors of rotavirus vaccine series initiation and completion were receipt of the diphtheria, tetanus and acellular pertussis vaccine (Initiation: RR = 7.91, 95% CI = 7.69-8.13; Completion: RR = 1.26, 95% CI = 1.23-1.29), visiting a pediatrician versus family physician (Initiation: RR = 1.51, 95% CI = 1.49-1.52; Completion: RR = 1.13, 95% CI = 1.11-1.14), and living in a large metropolitan versus smaller metropolitan, urban, or rural area. We observed rapid diffusion of the rotavirus vaccine in routine practice; however, approximately one-fifth of infants did not receive at least one dose of vaccine as recently as 2010. Interventions to increase rotavirus vaccine coverage should consider targeting family physicians and encouraging completion of the vaccine series.

Project description:INTRODUCTION:Benzodiazepines are commonly prescribed in the U.S. but entail safety concerns, including dependency. In pediatrics, many indications lack trial data. Authors aimed to describe youth initiating prescription benzodiazepine treatment, identify potential indications and prescribing concerns, estimate the duration of treatment by potential indication, and identify factors that predict long-term use. METHODS:The study cohort included children (aged 3-12 years) and adolescents (aged 13-17 years) initiating prescription benzodiazepine treatment (?3 days' supply) from January 2010 to September 2015 in a U.S. commercial claims database. Potential indications included selected ICD-9-CM diagnoses (?30 days prior). Long-term (?6 months) benzodiazepine treatment was estimated with Kaplan-Meier estimation and modified Poisson regression identified independent predictors of long-term benzodiazepine treatment (analysis completed in 2018). RESULTS:Of 24,504 children and 61,046 adolescents initiating benzodiazepines, 62% of the children and 68% of the adolescents had a potential indication. Anxiety disorders were the most common indication, with mental health indications more common among adolescents (45%) than children (23%) and epilepsy and movement disorders higher in children. Recent opioid prescriptions were common before benzodiazepine initiation (children, 22%; adolescents, 21%). Six percent of the initiators became long-term benzodiazepine users. Potential indication, provider contact, psychotropic medication, and chronic conditions independently predicted long-term benzodiazepine treatment in adolescents and children. CONCLUSIONS:U.S. children and adolescents are prescribed benzodiazepines for various mental health and other medical conditions, many lacking evidence of pediatric efficacy. Long-term benzodiazepine treatment, concurrent opioid prescriptions, psychotropic use, and prior substance use disorder diagnoses suggest safety risks among some youth prescribed benzodiazepines.

Project description:OBJECTIVE:To analyze utilization of, and payments for, pelvic organ prolapse procedures after the 2011 U.S. Food and Drug Administration (FDA) communication regarding transvaginal mesh. METHODS:This is a retrospective cohort study examining private claims from three insurance providers for inpatient and outpatient prolapse procedures from 2010 to 2013 in the Health Care Cost Institute. Primary outcomes were the change in utilization of prolapse procedures, with and without mesh, before and after the July 2011 FDA communication. Secondary outcomes were the changes in payments and reimbursements for these procedures. Utilization rates and payments were compared using generalized linear models and interrupted time-series analysis. RESULTS:Utilization of prolapse procedures decreased from 12.3 to 9.7 per 10,000 woman-years (P=.027) with a decrease of 30.7% (3.9 in 2010 to 2.7 in 2013, P=.05) in number of mesh procedures and 16.6% (8.4 in 2010 to 7.0 in 2013, P=.011) for nonmesh procedures. Quarterly utilization of mesh procedures was increasing before the FDA communication and then significantly declined after its release (slope=0.024 vs -0.025, P=.002). Nonmesh procedures, however, were already slightly decreasing before July 2011 and continued to decline at a more rapid pace after that time, although not significantly (slope=-0.004 vs -0.022, P=.47). Inpatient utilization decreased 52.2% (P=.002), whereas outpatient utilization increased 18.5% (P=.132). Payments for individual inpatient procedures, with and without mesh, increased by 12.0% ($8,315 in 2010 to $9,315 in 2013, P=.001) and 15.6% ($7,826 in 2010 to $9,048 in 2013, P=.005), respectively, whereas those for outpatient procedures increased by 41% ($4,961 in 2010 to $6,981 in 2013, P=.006) and 30% ($3,955 in 2010 to $5,149 in 2013, P=.004), respectively. CONCLUSION:Use of prolapse surgery declined during the study period. After the 2011 FDA communication regarding transvaginal mesh, there was a significant decrease in the utilization of procedures with mesh but not for those without mesh. A shift toward outpatient surgeries was observed, and payments for both individual inpatient and outpatient cases increased.

Project description:BackgroundKenya introduced the monovalent G1P [8] Rotarix® vaccine into the infant immunization schedule in July 2014. We examined trends in rotavirus group A (RVA) genotype distribution pre- (January 2010-June 2014) and post- (July 2014-December 2018) RVA vaccine introduction.MethodsStool samples were collected from children aged < 13 years from four surveillance sites across Kenya: Kilifi County Hospital, Tabitha Clinic Nairobi, Lwak Mission Hospital, and Siaya County Referral Hospital (children aged < 5 years only). Samples were screened for RVA using enzyme linked immunosorbent assay (ELISA) and VP7 and VP4 genes sequenced to infer genotypes.ResultsWe genotyped 614 samples in pre-vaccine and 261 in post-vaccine introduction periods. During the pre-vaccine introduction period, the most frequent RVA genotypes were G1P [8] (45.8%), G8P [4] (15.8%), G9P [8] (13.2%), G2P [4] (7.0%) and G3P [6] (3.1%). In the post-vaccine introduction period, the most frequent genotypes were G1P [8] (52.1%), G2P [4] (20.7%) and G3P [8] (16.1%). Predominant genotypes varied by year and site in both pre and post-vaccine periods. Temporal genotype patterns showed an increase in prevalence of vaccine heterotypic genotypes, such as the commonly DS-1-like G2P [4] (7.0 to 20.7%, P < .001) and G3P [8] (1.3 to 16.1%, P < .001) genotypes in the post-vaccine introduction period. Additionally, we observed a decline in prevalence of genotypes G8P [4] (15.8 to 0.4%, P < .001) and G9P [8] (13.2 to 5.4%, P < .001) in the post-vaccine introduction period. Phylogenetic analysis of genotype G1P [8], revealed circulation of strains of lineages G1-I, G1-II and P [8]-1, P [8]-III and P [8]-IV. Considerable genetic diversity was observed between the pre and post-vaccine strains, evidenced by distinct clusters.ConclusionGenotype prevalence varied from before to after vaccine introduction. Such observations emphasize the need for long-term surveillance to monitor vaccine impact. These changes may represent natural secular variation or possible immuno-epidemiological changes arising from the introduction of the vaccine. Full genome sequencing could provide insights into post-vaccine evolutionary pressures and antigenic diversity.
