Timeliness of Immunizations in CenteringParenting.

OBJECTIVE: To evaluate the timeliness of immunizations of children in CenteringParenting (Centering), a group well-child model, compared to children in individual well-child care. METHODS: We conducted a retrospective cohort study of infants born October 1, 2014 to February 18, 2019 with a 2-month and subsequent well-child visit, both Centering or individual, at an academic pediatric practice in an urban, low-income community. In Centering, same age infants/mothers and a provider meet for 10, 2-hour group visits, and facilitated discussions. Providers are trained in group facilitation and participate in both Centering and individual visits. Primary outcome was timeliness of immunizations at 7, 13, 19, and 25 months. Analyses were by intention to treat. RESULTS: The study population included 1735 children (Centering n = 342, individual n = 1393). By 25 months, 62% of children in Centering were up to date with all recommended immunizations compared to 44.2% of children in individual care, a 17.8% higher rate (P < .001). By 25 months, children in Centering made 3 additional well-child visits (9.2 vs 6.2, P < .001). Mediation analysis showed 82% of the effect on up to date status was due to increased attendance to well-child visits (P < .001); the remaining 18% was due to a Centering effect beyond the visit increase. CONCLUSIONS: Our study showed a strong association of CenteringParenting with timeliness of immunizations and adherence to well-child visits compared to individual visits in a low income community. These findings warrant further exploration of the impact of Centering in reducing health disparities in communities at risk.

Impact of a Baby-Friendly-Aligned Pacifier Policy on Pacifier Use at 1 Month of Age.

OBJECTIVE: Pacifier use decreases the risk of sudden infant death syndrome, but its impact on breastfeeding remains controversial. We evaluated the impact of a pacifier policy aligned with the World Health Organization and United Nations Children's Fund Baby-Friendly Hospital Initiative on subsequent pacifier use and breastfeeding at 1 month of age. METHODS: We conducted a prospective 2-stage (pre- and post-implementation) cohort study of newborns at a birth hospital before and after implementation of a Baby-Friendly-aligned pacifier policy. Consecutive mothers of newborns admitted to the nursery participated in a telephone survey when the infants were 1 month of age. RESULTS: In total, 342 mothers participated (190 before and 152 after implementation of the policy). Pacifier adoption was delayed in the post-implementation group, but pacifier use by 1 month of age was comparable (78.9% pre-implementation vs 77.6% post-implementation; P = .793). In the pre-implementation group, female and male infants used pacifiers at comparable rates; however, in the post-implementation group, females were significantly less likely to use a pacifier compared to males after controlling for insurance, race, parity, and delivery mode (adjusted odds ratio, 0.35; 95% confidence interval, 0.15-0.83; P = .02). In the post-implementation group, exclusive breastfeeding rates at discharge increased significantly (from 40% to 51.3%; P = .04), but rates were not different at 1 month (23.7% pre-implementation vs 24.3% post-implementation; P = .89). CONCLUSION: A Baby-Friendly-aligned pacifier policy delayed pacifier adoption but did not impact overall pacifier use or breastfeeding rates at 1 month of age. The finding of lower pacifier use rates among female infants post-intervention requires verification in other populations before evaluating public heath relevance.

Swaddling and Infant Sleeping Practices.

Swaddling promotes quiet sleep and may be a useful strategy to encourage infant safe sleep practices. We explored the effect of a swaddling education intervention on infant sleep practices in an urban minority community. We compared a cohort of postpartum mothers who were given education about swaddling to a historical group. Breastfeeding and pacifier use were similar in both groups. Compared to the historical group (n = 121), mothers in the swaddling group (n = 40) were more likely to swaddle infants to sleep (52.5 vs. 23.1 %, p = .001) and less likely to bedshare (15.4 vs. 33.1 %, p = .042). No significant effect was reported on infant supine sleep (81.6 vs. 69.4 %, p = .212). A postpartum swaddling education intervention had a limited impact on infant safe sleeping practices in an urban minority community. A recent metaanalysis demonstrated an increased risk of sudden infant death in infants swaddled for sleep and recommended the need to avoid the prone and side sleep position, especially for swaddled infants, and to set an age and developmentally appropriate limit for the use of swaddling. Ongoing studies are needed to monitor the safety and effectiveness of swaddling as a tool to promote safe sleeping in infants.

Exposure and Use of Mobile Media Devices by Young Children.

BACKGROUND AND OBJECTIVES: Research on children's use of mobile media devices lags behind its adoption. The objective of this study was to examine young children's exposure to and use of mobile media devices. METHODS: Cross-sectional study of 350 children aged 6 months to 4 years seen October to November 2014 at a pediatric clinic in an urban, low-income, minority community. The survey was adapted from Common Sense Media's 2013 nationwide survey. RESULTS: Most households had television (97%), tablets (83%), and smartphones (77%). At age 4, half the children had their own television and three-fourths their own mobile device. Almost all children (96.6%) used mobile devices, and most started using before age 1. Parents gave children devices when doing house chores (70%), to keep them calm (65%), and at bedtime (29%). At age 2, most children used a device daily and spent comparable screen time on television and mobile devices. Most 3- and 4-year-olds used devices without help, and one-third engaged in media multitasking. Content delivery applications such as YouTube and Netflix were popular. Child ownership of device, age at first use, and daily use were not associated with ethnicity or parent education. CONCLUSIONS: Young children in an urban, low-income, minority community had almost universal exposure to mobile devices, and most had their own device by age 4. The patterns of use suggest early adoption, frequent and independent use, and media multitasking. Studies are urgently needed to update recommendations for families and providers on the use of mobile media by young children.

Challenges and successes of immunization registry reminders at inner-city practices.

OBJECTIVES: To assess the effectiveness of two serial registry reminder protocols and the interactive effects of reminders with child characteristics on immunization rates. METHODS: At an inner city practice network in New York City we randomized 1662 children aged 6 weeks-15 months due or late for a diphtheria-tetanus-pertussis (DTaP) to 3 groups: continuous reminders (as needed), limited reminders (up to 3) and controls, for 6 months. Reminders were triggered by the hospital registry and immunizations were tracked with both the hospital and city registries. Analyses were based on intention to treat. RESULTS: At randomization, the study groups were comparable (9.2 months of age, 77% Latino, 86% Medicaid, 49.3% up-to date). A quarter of the children were sent false reminders, 15% had incorrect contact information, and 15% had missed opportunities for vaccination. In the univariate analysis, reminders improved coverage rates, but only for the children sent continuous reminders (51.2% vs. 44.9% controls, p < .01). Multivariate analysis showed reminders had no independent effect on immunization outcomes. Age, up-to-date and Medicaid status at randomization were strong predictors of a child receiving any subsequent immunization. However, reminders interacted synergistically with Medicaid to increase the likelihood of receiving an immunization. CONCLUSION: At an inner city practice network, registry reminders were not effective at improving immunization outcomes due to major system barriers. Immunization registries are powerful vehicles for identifying children in need of immunizations and generating reminders but system challenges must be addressed if this promise is to be achieved in inner city practices.

Use of personal digital assistants to enhance educational evaluation in a primary care clerkship.

Experiences of students using optically scanned cards were compared with those of students using personal digital assistants (PDAs) to log patient encounters in a primary care clerkship. From April to September 2001, students were offered the option of using a PDA in lieu of scanned cards to track clinical encounters. Data obtained from PDA users were compared with those previously obtained from scanned card users. Verbal and written feedback was obtained from all students. Of the 71 students invited to participate, 21 (30%) owned a PDA, and of these, 20 agreed to participate. Eighteen students completed the pilot. One student was unable to participate owing to software installation problems; another student lost data because of improper back-up. Students using the PDAs recorded more encounters per rotation and had fewer missing data when compared with students who used scanned card. Additionally, feedback from students suggested that PDAs offered other important educational benefits.
