Improving Health Outcomes for New Mothers and Babies

Because adherence to postnatal care guidelines across the United States (U.S.) is poor, newborns and mothers often are placed at undue risk for adverse medical and social outcomes. This study aims to evaluate an alternative model of care and improve healthcare delivery to and reduce health disparities for "well" newborns and mothers after hospital discharge by using single postnatal home nurse visits. The principal investigator has previously shown a reduction in poor outcomes for infants who receive a home visit after discharge when studied retrospectively. The proposed research will build on the previous study and prospectively evaluate the impact of a single home nursing visit on morbidities and health disparities for newborns and mothers in a randomized, controlled trial involving 1154 mother/infant breastfeeding dyads. Home visits should guarantee detailed assessment during an at-risk period of infancy and motherhood, where medical and social problems can be recognized, anticipated, and/or treated, and can bridge the gap between hospital care and primary care. The investigators' program, The Nurses for Infants Through Teaching and Assessment after the NurserY (NITTANY) Initiative, also will consider the cost-effectiveness of home visitation compared with guidelines-adherent outpatient clinic care.

In the NITTANY Initiative the effectiveness of a single postnatal/postpartum home nurse visit will be evaluated prospectively and compared with outpatient clinic-based care using a randomized, controlled study design. We will attempt to reduce morbidity in the neonatal/postpartum period using a well-timed home visit measured first by a reduction in the need for additional hospital services (inpatient hospitalization and ED visitation) in the first 14 days after delivery. While healthcare utilization may not be the most important health outcome for newborns and mothers from a long-term perspective, the demographic groups at-risk for these outcomes tend to parallel those at greater long-term risk. Also, in the short-term these outcomes may be the most costly ones for insurance providers and can be used in a cost-effectiveness analysis to justify home nurse visits. Readmissions and use of urgent care also may be the most noticeable outcome for clinicians, which should help to modify practice patterns and improve compliance with guidelines for healthcare delivery.

Over a 3-year period we will prospectively enroll a cohort of 1154 "well" singleton newborns and their mothers admitted to the hospital nursery that are most at-risk for readmission based on demographic features. Previous data have indicated those at greatest risk for adverse health outcomes are infants born to breastfeeding mothers and those with less parenting experience. Minorities and Medicaid recipients are more likely to suffer from healthcare disparities. For mothers, morbidities may occur in all socioeconomic groups, but those undergoing operative delivery or instrument assisted vaginal deliveries tend to suffer greater morbidity. In this study, patients will be randomized to receive usual, guideline adherent, post-discharge care with or without a home nurse visit 1-2 days after nursery discharge. For each newborn and mother, information from the pregnancy, obstetrical record, and the nursery course will be collected. Data also will be recorded regarding continuity of care during the perinatal period, hospital readmissions, ED visits, compliance with and extent of outpatient care, satisfaction with and convenience of care, and costs of healthcare. Method of infant feeding, maternal confidence, maternal depression and anxiety, and satisfaction with care will also be assessed.

To accomplish the objectives of this project, we will focus on the following 3 specific aims:

SPECIFIC AIM 1. Establish that single home nursing visits improve healthcare delivery to and reduce adverse health outcomes for breastfeeding newborns.

This model of home visitation will be shown to reduce postnatal morbidities, improve compliance with post-discharge guidelines, and reduce disparities in health outcomes for those enrolled in a prospective trial based on data presented under Preliminary Studies conducted by the PI. A randomized, controlled trial will be conducted over a period of 36 months to demonstrate that infants that receive a single home visit have a reduced need for subsequent hospital-based or non-scheduled urgent care services. Secondary outcomes of importance will include compliance with follow-up guidelines and breastfeeding rates that also are expected to improve in those receiving a home visit.

SPECIFIC AIM 2. Establish that single home nursing visits improve healthcare delivery to and reduce adverse outcomes for mothers who are breastfeeding their newborns. Maternal readmission, emergency department utilization, and need for non-scheduled urgent care services will be reduced in the group of women receiving a single, postpartum home visit compared with standard care. Additionally, parenting sense of competence, satisfaction with postpartum healthcare, level of perceived social support, and the incidence of postpartum depression and anxiety will be improved among women randomized to receive a home nursing visit during the stressful and emotional period following childbirth compared with those randomized to not receive a home visit.

SPECIFIC AIM 3. Prospectively evaluate the cost-effectiveness of a single postnatal home nursing visit after maternity/nursery hospital discharge.

Data from the trial will be used to perform a stochastic cost-effectiveness analysis to demonstrate prospectively that a single home nursing visit is cost-effective based upon the reduction of the need for subsequent hospital or non-scheduled urgent care based services (inpatient, emergency department, and outpatient) for newborns and mothers in the first 14 postnatal/postpartum days. Again based on the previous retrospective study conducted by the PI, home visits are expected to be a cost-effective intervention. Other factors including maternal health outcomes, breastfeeding, and long-term health and social outcomes will be assessed in terms of their relationship with cost.
