A Program Evaluation of Postpartum/Newborn Home Visitation Services in Aiken County, South Carolina

ABSTRACT Objective: Home visiting programs for very young children seek to promote their health and development. We conducted a process and outcome evaluation of the Postpartum/Newborn Home Visit (PPNBHV) service in 1 county.
Design: A retrospective study of Aiken County Health records of live infant births in 2004 was conducted.
Sample: A random sample of 176 infants who were born in 2004 and enrolled in the women, infants, and children's (WIC) program in the same year was selected.
Measures: Process measures include timeliness of the home visit, and appropriateness of revisits. Outcome measures include age at WIC enrollment and immunization status at 6/9 months.
Results: Of the 176 infants, 76 (43%) received a home visit. Of these, 13 (17%) received the visit within the stipulated time frame. After controlling for potential confounders, infants who received a home visit were 4 times (95% CI 1.92–8.36) as likely to enroll early in the WIC program compared with those who did not.
Conclusion: The PPNBHV service may contribute to early enrollment in the WIC program. Improvement in the timeliness of the visits is needed. Program monitoring and evaluation are necessary to ensure adherence, measure outcomes, and provide feedback for continuous quality improvement.     

Factors Associated with Parent Report of Access to Care and the Quality of Care Received by Children 4 to 17 Years of Age in Georgia

We examined factors associated with health care access and quality, among children in Georgia. Data from the 2007 National Survey of Children’s Health were merged with the 2008 Area Resource File. The medically underserved area variable was appended to the merged file, restricting to Georgia children ages 4–17 years (N = 1,397). Study outcomes were past-year access to care, defined as utilization of preventive medical care and no occasion of delay or denial of needed care; and quality of care received, defined as compassionate, culturally-effective, and family-centered care which was categorized as higher, moderate, or lower. Analysis included binary and multinomial logit modeling. In our study population, 80.8 % were reported to have access to care. The quality of care distribution was: higher (39.4 %), moderate (30.6 %), and lower (30.0 %). Younger age (4–9 years) was positively associated with having access to care. Compared to children who had continuous and adequate private insurance, children who were never/intermittently insured or who had continuous and inadequate private insurance were less likely to have access. Compared to children who had continuous and adequate private insurance, there were lower odds of perceiving received care as higher/moderate versus lower quality among children who were never/intermittently insured or who had continuous and inadequate/adequate public insurance. Being in excellent/very good health and living in safe/supportive neighborhoods were positively associated with quality; non-white race/ethnicity and federal poverty level were negatively associated with quality. Assuring continuous, adequate insurance may positively impact health care access and quality.     

Long-Term Effects of Breastfeeding,Maternal Smoking During Pregnancy,and Recurrent Lower Respiratory Tract Infections on Asthma in Children

The effect of breastfeeding on asthma is controversial, which may be explained by related and interacting early childhood risk factors. We assessed the joint effects of a risk-triad consisting of maternal smoking during pregnancy, breastfeeding for less than 3 months, and recurrent lower respiratory tract infections (RLRTI) on physician-diagnosed childhood asthma. The association was assessed in the Isle of Wight birth cohort study (1989–1990) using a repeated measurement approach with data collection at birth, and at ages 1, 2, 4, and 10 years. The population consists of 1,456 children recruited between January 1989 and February 1990. Prenatal smoking, breastfeeding for less than 3 months, and recurrent lower respiratory infections (RLRTI) were combined into eight risk-triads. Relative risks (RR) and 95% confidence intervals were estimated with a log-linear model. The risk-triad involving RLRTI in infancy, maternal smoking during pregnancy, and breastfeeding for less than 3 months showed a stronger association with asthma at ages 4 and 10 compared to other risk-triads (RR of 5.79 for any asthma at ages 1, 2, 4, and 10; and 3.1 for asthma at ages 4 and 10). Of the three individual risk factors, RLRTI appeared to be the major driver of the combined effects in the risk-triads. The effect of RLRTI on asthma was modified by breastfeeding. Breastfeeding for ≥ 3 months also attenuated the effect of prenatal smoking on asthma in children without RLRTI. A high proportion of asthma cases in childhood can be prevented by promoting breastfeeding, by preventing smoking during pregnancy, and by avoidance of recurrent lower respiratory tract infections in early childhood.     

Predictors of time to enter medical care after a new HIV diagnosis: a statewide population-based study

Public health benefits of expanded HIV screening will be adequately realized only if an early diagnosis is followed by prompt linkage to care. We characterized rates and factors associated with failure to enter into medical care within three months of HIV diagnosis and assessed the predictors of time to enter care over a follow-up period of up to 60 months. The study cohort included 3697 South Carolina (SC) residents' ≥13 years who were newly HIV-diagnosed in 2004-2008. Date of first laboratory report of CD4(+) T-cell count or viral load (VL) test after 30 days of confirmatory HIV diagnosis was used to define time to linkage to care. Results showed that of the total 3697 persons, 1768 (48%) entered care within three months, 1115 (30%) in four-12 months after diagnosis, and 814 (22%) failed to initiate care within 12 months of HIV diagnosis. At the end of study follow-up period of up to 60 months from the date of HIV diagnosis, 472/3697 (13%) individuals remained out of care. Multivariable Cox proportional hazards analysis showed that compared with hospitals, time to enter care was shorter in those diagnosed at state mental health/correctional facilities (adjusted hazards ratio [aHR] 1.16; 95% confidence interval [CI] 1.02-1.34) and longer in those diagnosed at county health departments (aHR 0.87; 95% CI 0.80-0.96) and at "Other/unknown" facilities (aHR 0.79; 95% CI 0.70-0.89). Time to entry into care was longer for men (aHR 0.82; 95% CI 0.75-0.89) compared with women, blacks (aHR 0.91; 95% CI 0.83-0.98) compared with whites, and males who have sex with males (MSM) (aHR 0.89; 95% CI 0.80-0.98) compared with heterosexual exposure. Delayed entry into HIV care remains a challenge in controlling HIV transmission in SC. Better integration of testing and care facilities could improve the proportion of newly HIV-diagnosed persons who enter care in a timely manner.     

Adverse events following a third dose of measles,mumps, and rubella vaccine in a mumps outbreak

During a 2009–2010 mumps outbreak in a New York State village, a third dose of measles, mumps, and rubella (MMR) vaccine was administered to children in three schools as a control measure. Information on local and systemic adverse events (AE) was collected by a self-report survey distributed to all children in grades 6–12. A comprehensive search for AE following MMR vaccination was conducted using physician records and the Vaccine Adverse Events Reporting System (VAERS). A literature search was performed for published reports pertaining to AE associated with mumps-containing vaccine, using the Jeryl-Lynn strain, from 1969 to 2011. A total of 1755 individuals received the third dose; 1597 (91.0%) returned the survey. Of those, 115 (7.2%) reported at least one local or systemic AE in the 2 weeks following vaccination. The most commonly reported AE were “pain, redness, or swelling at the injection site” (3.6%) and “joint or muscle aches” (1.8%). No serious AE were reported in the survey, physician records or through VAERS. The proportions of AE found in the present study were lower than or within the range of those reported in prior studies of first- and second-dose MMR vaccine studies. The results of this study suggest that a third dose of MMR vaccine administered in an outbreak setting is safe, with injection site reactions reported more frequently than systemic reactions. However, to assess risk for rare or serious AE after a third dose of MMR vaccine, longer term studies would be required.     

Impact of maternal characteristics on the effect of maternal influenza vaccination on fetal outcomes

Background

Maternal infections during pregnancy have been associated with adverse fetal and infant health outcomes, and vaccination against influenza is the most effective tool to prevent morbidity and mortality due to seasonal and pandemic influenza. We evaluated the association between receipt of the inactivated seasonal influenza vaccine on preterm and small for gestational age (SGA) births, with the aim to assess racial and socioeconomic variations in vaccine effect.

Methods

We conducted a retrospective analysis of state-wide surveillance data from Georgia for the most recent four years available at the beginning of the study, a total of 8393 live births in Georgia from January 1, 2005 through December 31, 2008. We constructed multivariable logistic regression models and calculated odds ratios (OR) estimates with corresponding 95% confidence intervals (CI) to evaluate the effect of maternal influenza vaccination on SGA (birth weight <10th percentile for gestational age) and preterm (gestational age at birth <37 weeks) births while controlling for potential confounders.

Results

Among all women, we found significant strong associations between maternal influenza vaccination and reduced odds of a preterm birth during the widespread influenza activity period [OR = 0.39, 95% CI: 0.18, 0.83]. In this period, vaccination was protective against SGA births among women at higher risk for influenza related morbidity – women enrolled in the Women, Infant and Child (WIC) program [OR = 0.20, 95% CI: 0.04, 0.98] and Black women [OR = 0.15 95% CI: 0.02, 0.94]; maternal influenza vaccination was associated with reduced odds of a preterm birth among white women [OR = 0.34, 95% CI: 0.12, 0.91] and women of higher socio-economic status [OR = 0.30, 95% CI: 0.12, 0.74].

Conclusion

Influenza vaccination during pregnancy was significantly associated with reduced odds of small for gestational age and preterm births during the widespread influenza activity period. Vaccination effects varied by socio-demographic characteristics.
