Prenatal care programs in a clinic based center in El Paso, Texas: Evaluating outcomes among Hispanic women

Early prenatal care has been found to improve pregnancy and birth outcomes by reducing the risk of low birth weight and preterm births. Statistics point to lower utilization rates of prenatal care in El Paso, Texas and increasing rates of low birth weight. This study was a secondary data analysis, which explored the perceived benefits and barriers known to influence the utilization of prenatal care, and the birth outcomes among participating subjects attending three different prenatal care programs offered at the Centro San Vincent Clinic during the period of December 2006 to February 2008. A survey was used to collect data on demographics and assess perceived benefits and barriers regarding early prenatal care and self-efficacy of the participants. Post-partum birth records were used to gather data about the participant's newborns to include birth weight, gestational age, and the type of delivery (i.e. vaginal versus Cesarean birth). Chi square analysis was conducted to test for significant differences and associations. The sample of women in the study had high risk factors for inadequate utilization of prenatal care. In spite of high demographic risk factors, these women had higher perceived benefits, lower perceived barriers and high self-efficacy associated with prenatal care utilization. The perceived benefits and barriers to prenatal care were associated with place of birth and language preferred, with women from Mexico and who preferred Spanish having higher perceived benefits and lower barriers. There was no significant difference in birth outcomes among the women in different prenatal care programs. The findings of this study suggest that of all participants in the study, those born in Mexico demonstrated higher rates of perceived benefits of early prenatal care. The analysis also suggested that healthy birth outcomes were evenly distributed among women participating in one of the three prenatal care programs. ^

Impact of maternal Tdap vaccination on pertussis infection in young infants

Undiagnosed infected mothers often are the source of pertussis illness in young infants. The Centers for Disease Control and Prevention (CDC) recommends Tdap vaccine for post-partum women before hospital discharge. This intervention has been implemented at Ben Taub General Hospital (BTGH) in Houston, TX since January 2008. Our objective was to compare the proportion of infants born at BTGH and developing pertussis to the total number of pertussis cases before and after the intervention. Methods. We conducted a cross-sectional comparative study between the pre-intervention (7/2000 to 12/2007) and post-intervention (1/2008 to 5/2009) periods. Information on pertussis diagnosis was determined using ICD-9 codes, infection control records, and molecular microbiology reports from Texas Children's Hospital (TCH) and BTGH. Only patients ≤ 6 months of age with laboratory-confirmed B. pertussis infection were included in the study. Results. 481 infants had pertussis illness; 353 (73.3%) during pre-intervention and 128 (26.6%) during post-intervention years. The groups were comparable in all measures including age (median 73 vs. 62.5 days; p=0.08), gender (males 54.2%; p=0.47), length of hospitalization (median 9.8 vs. 4 9.5 days; p=0.5), outcomes (2 deaths in each period; p=0.28) and pertussis illness at TCH (95.2% vs. 95.3%; p=0.9). The proportion of pertussis patients born at BTGH, and thus amenable to protection by the intervention, was not statically different between the two periods after adjusting for age, gender and ethnicity (7.3% vs. 9.3%; an OR=1.05, 95% CI 0.5-2.1, p=0.88). Conclusions. Vaccinating only mothers with Tdap in the post-partum period does not reduce the proportion of pertussis in infants age ≤ 6 months. Efforts should be directed at Tdap immunization of not only mothers, but also all household and key contacts of newborns to protect them against pertussis illness before the primary DTaP series is completed.^

The effects of adequacy and content of prenatal care on birth outcomes in a high -risk Missouri population

The purpose of this observational study was investigation of the relationship between quantitative adequacy of prenatal care, specific prenatal care content and pregnancy outcome in a high risk Missouri population. A sample of 1484 women from three Missouri regions known to have high rates of low birth weight, infant mortality, and inadequate prenatal care rates participated in structured post-partum interviews. Approximately one-half of the sample had received adequate prenatal care and the other half inadequate prenatal care as determined by an index utilized by the Missouri Department of Health.^ Prenatal care content was assessed by reports of prenatal education in six different areas: Diet, smoking, alcohol, drug, preterm labor counseling, and advice on when to call the health provider if preterm labor was suspected by the woman. Low birth weight, in both term and preterm infants, were the two birth outcomes examined. A variety of maternal socio-demographic variables were also considered.^ The results of this study suggest that specific educational content, delivered during prenatal care, may have lessen the risk of giving birth to a preterm-low birth weight infant. Prenatal education for recognition of preterm labor, and advice on when to call the health provider if preterm labor was suspected were found to be associated with a decreased risk of preterm delivery. Specific educational content was not, however, associated with risk of term-low weight birth nor was quantitative adequacy of care associated with the risk of either term- or preterm-low birth weight.^ These findings reinforce a body of literature which stresses the importance of appropriate prenatal care in preventing preterm low birth weight. Additionally, the findings suggest interventions that may be specifically effective for prematurity prevention. ^

Correlates of prenatal care initiation among low -income Hispanic women

Because Hispanic women are even less likely than women of other ethnic groups to receive early prenatal care, the purpose of this study was to identify factors that may influence these women to initiate care. After giving consent, 300 Hispanic women (100 who initiated first trimester care, 100 who initiated second trimester care, and 100 who initiated third trimester care or received no care) were interviewed in the post partum unit of a local public hospital. The interview included recollection of events leading to the first prenatal appointment, including first physical indicators of pregnancy, confirmation of pregnancy, feelings about the pregnancy, appointment making behavior, and system barriers encountered. The Health Belief Model was used as the theoretical framework for determining psychosocial variables. Using this model, perceived susceptibility to problems during pregnancy, perceived seriousness of possible problems, perceived benefits of prenatal care, perceived barriers to care, and cues to action were assessed. Time of entry into prenatal care was assessed by interview.^ In this sample of low-income Hispanic women, a higher perception of barriers to care was associated with later initiation of care and non-use of care, higher perceived benefits of care for the baby were associated with earlier care, especially in women without a card to access hospital district services, and having a card to access hospital district services was associated with earlier care. Several barriers to care were mentioned by women on open-ended questioning including long waiting times, embarrassment, and lack of transportation.^ Recommendations for practice included decreasing the number of visits for low-risk women while increasing the time spent with the provider, decreasing the number of vaginal exams for low-risk women, increasing the use of midwives, training lay workers to do risk assessment, giving specific messages about benefits of care to baby, and increasing general health motivation through community intervention methods. More research on the psychosocial and cultural factors associated with initiation of care is needed. In the meantime, the recommendations for practice can be implemented now to increase the use of prenatal care by low-income Hispanic women. ^
