Obstetric Volume and Severe Maternal Morbidity Among Low-Risk and Higher-Risk Patients Giving Birth at Rural and Urban US Hospitals
Open AccessKaty B Kozhimannil, Stephanie A Leonard et al.ARTICLEJAMA Health Forum2023
In this cross-sectional study of births in US rural and urban counties, risk of SMM was elevated for low-risk and higher-risk obstetric patients who gave birth in lower-volume hospitals in rural counties, compared with similar patients who gave birth at rural hospitals with greater than 460 annual births. These findings imply a need for tailored quality improvement strategies for lower volume hospitals in rural communities
Improving the Maternity Care Safety Net
Open AccessJoan Combellick, Bridget Basile Ibrahim et al.ARTICLEInternational Journal of…2023
The siloed nature of maternity care has been noted as a system-level factor negatively impacting maternal outcomes. Veterans Health Administration (VA) provides multi-specialty healthcare before, during, and after pregnancy but purchases obstetric care from community providers. VA providers may be unaware of perinatal complications, while community-based maternity care providers may be unaware of upstream factors affecting the pregnancy. To optim…

Readying the Workforce
Natalya C Maisel, Sally G Haskell et al.ARTICLEMedical Care2015Referencias: 8
BACKGROUND: Veterans Health Administration (VHA) primary care providers (PCPs) often see few women, making it challenging to maintain proficiency in women's health (WH). Therefore, VHA in 2010 established Designated WH Providers, who would maintain proficiency in comprehensive WH care and be preferentially assigned women patients. OBJECTIVE: To evaluate early implementation of this national policy. METHODS: At each VHA health care system (N=140),…

Gender Disparities in Veterans Health Administration Care
Susan M Frayne, Elizabeth M Yano et al.ARTICLEMedical Care2008Referencias: 11
BACKGROUND: In an effort to assess and reduce gender-related quality gaps, the Veterans Health Administration (VHA) has promoted gender-based research. Historically, such appraisals have often relied on secondary databases, with little attention to methodological implications of the fact that VHA provides care to some nonveteran patients. OBJECTIVES: To determine whether conclusions about gender differences in utilization and cost of VHA care cha…

The Economic Implications of Prenatal Substance Exposure
Ciaran S PhibbsARTICLEThe Future of Children1991
Although economic research has not yet produced accurate estimates of the total cost of prenatal substance exposure, there is growing evidence that this exposure may result in large short-term expenditures for newborn medical intensive care and probably even larger long-term medical, social, and educational expenditures. The annual short-term economic costs due to maternal smoking are estimated to be from $332 million to $652 million (in 1986 dol…

Determinants of Readmission Following Inpatient Substance Abuse Treatment
Keith A Peterson, Ralph W Swindle et al.ARTICLEMedical Care1994
This study examines program determinants of one aspect of VA inpatient substance abuse treatment program performance. Performance was measured by the ratio of a program's readmission rate to the expected rate for programs with similar patients. Six-month readmission rates in 101 VA treatment programs were analyzed. Preliminary analyses indicated that patient differences across programs accounted for 36% of the variance in readmission rates. Progr…
