Abstract

Objective: To describe the prevalence, trends, adverse maternal-fetal morbidities and healthcare costs associated with placenta accreta (PA) in the United States (US) between 1998 and 2011.Methods: A retrospective, cross-sectional analysis of inpatient hospital discharges was conducted using the National Inpatient Sample (NIS). We used International Classification of Diseases, Ninth Edition, Clinical Modification (ICD-9-CM) codes to identify both cases of PA and of selected comorbidities. Survey logistic regression was used to assess the association between PA and various maternal-fetal outcomes. Joinpoint regression modeling was used to estimate annual percent changes (APCs) in PA prevalence during the study period.Results: The prevalence of PA from 1998 to 2011 was 3.7 per 1000 delivery-related discharges. After adjusting for known or suspected confounders, PA conferred between a 20% to over a 19-fold increased odds of experiencing an adverse outcome. This resulted in a higher mean, per-hospitalization, cost of inpatient care after adjustment for inflation (5561 versus 4989), translating into over 115 million dollars in additional inpatient expenditures relative to non-PA affected deliveries from 2001 to 2011.Conclusions: This study updates recent trends in the prevalence of PA, which is valuable to clinicians and policymakers as they formulate targeted strategies to address factors related to PA.
