Substantial barriers to WCC among low socioeconomic families can limit achievement of this outcome. Quality improvement strategies have been widely adopted in healthcare but only recently implemented in home visiting to achieve program outcomes. The objective of this initiative was to increase the percentage of infants enrolled in home visiting who completed at least 3 recommended WCC visits in the first 6 months of life within a large, multi-model program comprised of 11 sites. A series of 33 quality improvement cycles were conducted at 3 sites involving 18 home visitors and 139 families with infants in the target age range. These were deployed sequentially, and changes within and across sites were monitored using trend charts over time. Adopted strategies were then implemented program-wide.

Home visiting programs are voluntary and family engagement and retention in service can influence outcomes. Most participants receive less home visits and for a shorter time than prescribed by evidence-based models. The purpose of this study was to evaluate community-based enrichment of HV (CBE-HV), an approach that was developed and implemented to increase engagement and retention in HV. CBE-HV strategies included (1) community engagement, (2) ancillary supports for families in HV, and (3) enhancements to a HV program. A retrospective, quasi-experimental study was conducted to estimate the effect of CBE-HV on the retention of families in a HV program. Comparisons of study participants were made post-implementation of CBE-HV (n = 2191) and over time (n = 3786)-pre- versus post-CBE-HV implementation in the study communities. The CBE-HV effect was statistically significant and protective (hazards ratio [HR] 0.77, 95 % confidence interval [CI]: 0.67, 0.88), indicating that attrition from HV was 23 % less in the CBE-HV group relative to the post-implementation comparison group. In the temporal comparison of study communities, CBE-HV was also associated with a significantly lower risk of HV attrition (HR: 0.71, 95 % CI: 0.56, 0.89). The study demonstrated that CBE-HV is a promising approach to achieve stronger retention and engagement in HV. Further research is needed to identify the components of CBE-HV approaches that are most effective.

The current aim was to develop and validate a risk tool grounded in social determinants theory for use among at-risk Medicaid patients. This was a retrospective cohort study of 409 women across 17 Cincinnati health centers between September 2013 and April 2014. The primary outcomes included preterm birth, low birth weight, intrauterine fetal demise, and neonatal death. After random allocation into derivation and validation samples, a multivariable model was developed, and a risk scoring system was assessed and validated using area under the receiver operating characteristic curve (AUROC) values. The derived multivariable model (n=263) included: prior preterm birth, interpregnancy interval, late prenatal care, comorbid conditions, history of childhood abuse, substance use, tobacco use, body mass index, race, twin gestation, and short cervic...

This was a retrospective, matched case-control study of late-preterm infants receiving care across 8 regional hospitals in 2009 in the United States. Those readmitted within 28 days of birth were matched to non-readmitted infants at a ratio of 1:3 according to birth hospital, birth month, and gestational age. Step-wise modeling with likelihood ratio tests were used to develop a multivariable logistic regression model. A subgroup analysis of hyperbilirubinemia readmissions was also performed. Of 1861 late-preterm infants delivered during the study period, 67 (3.6%) were readmitted within 28 days of birth. These were matched to 201 control infants, for a final sample of 268 infants. In multivariable regression, each additional day in length of stay was associated with a significantly reduced odds ratio (OR) for readmission (0.57, P = .004); ...

Medical records were reviewed to obtain data on all TcB measurements collected during two 2-week periods on neonates admitted to participating newborn nurseries. Data on TSB levels obtained within 2 hours of a TcB measurement were also abstracted. TcB - TSB differences and correlations between the values were determined. Data on demographic information for individual newborns and TcB screening practices for each nursery were also collected. Multivariate regression analysis was used to identify characteristics independently associated with the TcB - TSB difference. Data on 8319 TcB measurements were collected at 27 nursery sites; 925 TSB levels were matched to a TcB value. The mean TcB - TSB difference was 0.84 ± 1.78 mg/dL, and the correlation between paired measurements was 0.78. In...

We evaluated how hospital practices affect breastfeeding by gestational age. This Listening to Mothers III survey cohort included 1,860 mothers who delivered a 34-41-week singleton from July 2011 to June 2012. High hospital support was defined as at least seven practices consistent with the Baby-Friendly Hospital Initiative&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;#39;s Ten Steps for United States hospitals. Logistic regression tested mediating effects of hospital support on the relationship between gestational age and breastfeeding at 1 week postpartum. High hospital support was associated with increased exclusive breastfeeding (AOR 2.21 [95% CI 1.58-3.09]). Just 16.4 percent of late preterm infants experienced such support, compared with early-term (37.9%) and term (30.7%) infants (p = 0.004). Although overall breastfeeding rates among late preterm, early-term, and term infants were 87, 88, and 92 percent, respectively, (p = 0.21), late preterm versus term infants were less likely to exclusively breastfeed (39.8 vs. 62.3%, p = 0.002). Inclusion of hospital support in multivariable modeling did not attenuate the effect of late preterm gestation. Differences in practices do not account for decreased exclusive breastfeeding among late preterm infants. Hospital supportive practices increase the likelihood of any breastfeeding.

Home visiting programs seek to improve care management for women at high risk for preterm birth (<37 weeks). Our objective was to evaluate the effect of home visiting dosage on preterm birth and small for gestational age (SGA) infants. METHODS:
Retrospective cohort study of women in southwest Ohio with a singleton pregnancy enrolled in home visiting before 26 weeks’ gestation. Vital statistics and hospital discharge data were linked with home visiting data from 2007 to 2010 to ascertain birth outcomes. Eligibility for home visiting required ≥1 of 4 risk factors: unmarried, low income, <18 years of age, or suboptimal prenatal care. Logistic regression tested the association of gestational age at enrollment and number of home visits before 26 weeks with preterm birth. Proportional hazards analysis tested the association of total number of home visits with SGA status. RESULTS:
Among 441 participants enrolled by 26 weeks, 10.9% delivered preterm; 17.9% of infants were born SGA. Mean gestational age at enrollment was 18.9 weeks; mean number of prenatal home visits was 8.2. In multivariable regression, ≥8 completed visits by 26 weeks compared with ≤3 visits was associated with an odds ratio 0.38 for preterm birth (95% confidence interval: 0.16–0.87), while having ≥12 total home visits compared with ≤3 visits was significantly associated with a hazards ratio 0.32 for SGA (95% confidence interval: 0.15–0.68). CONCLUSIONS:
Among at-risk, first time mothers enrolled prenatally in home visiting, higher dosage of intervention is associated with reduced likelihood of adverse pregnancy outcomes.

We used a probabilistic and deterministic linking strategy to join vital records, hospital discharge records, and home visiting data for a population-based cohort of at-risk, first time mothers enrolled in a regional home visiting program in Southwestern Ohio and Northern Kentucky from 2007 to 2010. Because data sources shared no universal identifier, common identifying elements were selected and evaluated for discriminating power. Vital records then served as a hub to which other records were linked. Variables were recoded into clinically significant categories and a cross-set of composite analytic variables was constructed. Finally, individual-level data were linked to corresponding area-level measures by census tract using the American Communities Survey. The final data set represented 2,330 maternal-infant pairs with both home visiting and vital records data. Of these, 56 pairs (2.4 %) did not link to either maternal or infant hospital discharge records. In a 10 % validation subset (n = 233), 100 % of the reviewed matches between home visiting data and vital records were true matches. Combining multiple data sources provided more comprehensive details of perinatal health service utilization and demographic, clinical, psychosocial, and behavioral characteristics than available from a single data source. Our approach offers a template for leveraging disparate sources of data to support a platform of research that evaluates the timeliness and reach of home visiting as well as its association with key maternal-child health outcomes.

Our objective was to determine the association between care coordination and timing of newborn follow-up. Methods This retrospective study evaluated 6251 newborns from eight maternity hospitals who scheduled a primary care appointment at one of two academic pediatric practices over 3.5 years. Two programs were sequentially implemented: (1) newborn discharge coordination, and (2) primary care intake coordination. Primary outcome was days between discharge and follow-up, dichotomized as ≤ or >5 days. Number of rescheduled appointments and loss to follow-up were also assessed. Adjusted relative risks (RR) and odds ratios (OR) were determined by piecewise generalized linear and logistic regression. Results Among 5943 newborns with a completed visit, 52.9 % were seen within 5 days of discharge (mean 6.7 days). After multivariable adjustment...
