Effects of a Multi-site Expansion of Group Prenatal Care on Birth Outcomes.

Objectives Perinatal Quality Collaboratives across the United States are initiating projects to improve health and healthcare for women and infants. We compared an evidence-based group prenatal care model to usual individual prenatal care on birth outcomes in a multi-site expansion of group prenatal care supported by a state-wide multidisciplinary Perinatal Quality Collaborative. Methods We analyzed 15,330 pregnant women aged 14-48 across 13 healthcare practices in South Carolina (2013-2017) using a preferential-within cluster matching propensity score method and logistic regression. Outcomes were extracted from birth certificate data. We compared outcomes for (a) women at the intent-to-treat level and (b) for women participating in at least five group prenatal care visits to women with less than five group visits with at least five prenatal visits total. Results In the intent-to-treat analyses, women who received group prenatal care were significantly less likely to have preterm births (absolute risk difference - 3.2%, 95% CI - 5.3 to - 1.0%), low birth weight births (absolute risk difference - 3.7%, 95% CI - 5.5 to - 1.8%) and NICU admissions (absolute risk difference - 4.0%, 95% CI - 5.6 to - 2.3%). In the as-treated analyses, women had greater improvements compared to intent-to-treat analyses in preterm birth and low birth weight outcomes. Conclusions for Practice CenteringPregnancy group prenatal care is effective across a range of real-world clinical practices for decreasing the risk of preterm birth and low birth weight. This is a feasible approach for other Perinatal Quality Collaboratives to attempt in their ongoing efforts at improving maternal and infant health outcomes.

The effects of CenteringPregnancy group prenatal care on postpartum visit attendance and contraception use.

OBJECTIVE: We examined whether Medicaid-enrolled women in CenteringPregnancy group prenatal care had higher rates of (1) postpartum visit attendance and (2) postpartum uptake of contraceptives, compared to women in individual prenatal care. STUDY DESIGN: We linked birth certificates and Medicaid claims for women receiving group prenatal care in 18 healthcare practices and applied preferential-within cluster propensity score methods to identify a comparison group, accounting for the nested data structure by practice. We examined five standardized, claims-based outcomes: postpartum visit attendance; contraception within 3 days; and any contraception, long-acting reversible contraception (LARC), and permanent contraception within eight weeks. We assessed outcomes using logistic regression for two treatment levels: (1) any group attendance compared to no group attendance and (2) attendance at five or more group sessions to at least five prenatal care visits, including crossovers attending fewer than five group sessions (minimum threshold analysis). RESULTS: Women attending at least five group sessions had higher rates of postpartum visit attendance (71.5% vs. 67.5%, p < .05). Women with any group attendance (N = 2834) were more likely than women with individual care only (N = 13,088) to receive contraception within 3 days (19.8% vs. 16.9%, p < .001) and to receive a LARC within eight weeks' postpartum (18.0% vs. 15.2%, p < .001). At both treatment levels, group participants were less likely to elect permanent contraception (5.9% vs. 7.8%, p < 0.001). Women meeting the five-visit group threshold were not more likely to initiate contraception or LARCs within 8 weeks' postpartum. CONCLUSION: Participation in at least five group compared to five individual prenatal care visits is associated with greater rates of postpartum visit attendance. Additional engagement and education in group prenatal care may influence postpartum visit attendance. IMPLICATIONS: Planning for postpartum care and contraception during prenatal care is an important strategy for connecting women to postpartum healthcare. Regardless of prenatal care model, women have low uptake of contraception in the postpartum period. Increased use of group prenatal care with its scheduled family planning discussion may help to increase postpartum contraceptive uptake. This benefit is dependent on availability of postpartum contraception options.

Long-term acute care hospitals and Georgia Medicaid: Utilization, outcomes, and cost.

OBJECTIVES: Because most research on long-term acute care hospitals has focused on Medicare, the objective of this research is to describe the Georgia Medicaid population who received care at a long-term acute care hospital, the type and volume of services provided by these long-term acute care hospitals, and the costs and outcomes of these services. For those with select respiratory conditions, we descriptively compare costs and outcomes to those of patients who received care for the same services in acute care hospitals. METHODS: We describe Georgia Medicaid recipients admitted to a long-term acute care hospital between 2011 and 2012. We compare them to a population of Georgia Medicaid recipients admitted to an acute care hospital for one of five respiratory diagnosis-related groups. Measurements used include patient descriptive information, admissions, diagnosis-related groups, length of stay, place of discharge, 90-day episode costs, readmissions, and patient risk scores. RESULTS: We found that long-term acute care hospital admissions for Medicaid patients were fairly low (470 90-day episodes) and restricted to complex cases. We also found that the majority of long-term acute care hospital patients were blind or disabled (71.2%). Compared to patients who stayed at an acute care hospital, long-term acute care hospital patients had higher average risk scores (13.1 versus 9.0), lengths of stay (61 versus 38 days), costs (US$143,898 versus US$115,056), but fewer discharges to the community (28.4% versus 51.8%). CONCLUSION: We found that the Medicaid population seeking care at long-term acute care hospitals is markedly different than the Medicare populations described in other long-term acute care hospital studies. In addition, our study revealed that Medicaid patients receiving select respiratory care at a long-term acute care hospital were distinct from Medicaid patients receiving similar care at an acute care hospital. Our findings suggest that state Medicaid programs should carefully consider reimbursement policies for long-term acute care hospitals, including bundled payments that cover both the original hospitalization and long-term acute care hospital admission.
