Abstract

Objective: to analyze the general and specific evolution (refined cases, mean cost, weights, and refined mean stay) in obstetric DRGs and Major Diagnostic Categories (MDCs) 14 and 15, in the period between the years 2000 and 2015, as well as to highlight any existing differences between autonomous communities.
Method: a narrative review of the literature available in the following secondary databases: PubMed, Cochrane and Medes. A search strategy consisting in a combination of DeCS key descriptors (Diagnosis Related Groups, Information Systems, Statistical Data Interpretation, Cost-Benefit Analysis, Prospective Payment System, Obstetrics), and a longitudinal descriptive study with data obtained from the statistical website by the Ministry of Health, Social Services and Equality. A descriptive analysis. Linear regression model was used in order to conduct the predictive study, through the R software version 3.2.323.
Results: there was a selection of 11 documentary references useful for analysis, though none of them had an obstetric reference. Over 42,000 entries were analyzed from the statistical website of the Ministry of Health, Social Services and Equality; the variables selected were the number of cases recorded by DRG and MDC, mean cost, average Spanish weight, and refined mean stay.
Conclusions: overall, it can be said that in the 2000-2015 period, obstetric DRGs were reduced in terms of number of cases and mean stay, and the relative weight was sustained (estimated use of resources and costs); however, the increase in cost per DRG was superior in average to the current annual price index.
