Health care costs associated with changing clinics and "walk-in" deliveries: evidence supporting a regionalized health information network.
OBJECTIVE
The objective of the study was to describe the prevalence of changing clinics and "walk-in" deliveries and estimate associated health care costs.


METHODS
This was a retrospective review at an urban teaching hospital over a 6 month period. Principal outcome measures were availability of laboratory data at delivery and the number, type, and costs of duplicated tests for patients receiving various amounts of prenatal care (PNC) at our site. The prevalence of changing clinics, walk-in deliveries, and availability of records in our hospital was applied to the Los Angeles County Medicaid population to calculate the estimated cost of repeated prenatal laboratory studies.


RESULTS
Of the 1120 patients delivered by our service, 50% received all PNC at our site, 27% transferred PNC to our site, and 23% of patients were walk-ins for delivery only. Medical records were unavailable in 26% of cases, requiring prenatal laboratory studies repeated. Costs varied by amount of PNC on site (range, $107.00-201.00).


CONCLUSIONS
Changing clinics and walk-in deliveries are associated with significant health care costs because of redundant laboratory services and personnel costs associated with reviewing and exchanging medical records.
