[Comparative study of a neonatology unit by means of 2 patient grouping technics]

In this study we make a measurement of the case-mix of the neonatology section in Hospital Puerta del mar in Cadiz during the year 1990, through two methods: Diagnosis Related Groups (GRDs), and Patient Management Categories (PMCs). We compare this case-mix with other hospitals. We compare this case mix with other hospitals. We also compare both methods between themselves through a multiple lineal regression. The results point out that the complexity of casuistry attended in Cadiz was lower to those attended in other control hospitals, and that these ones worked more efficiently. As for comparison of both technics, the GRDs demonstrated to have a superior capacity than the PMCs to discriminate the casuistry.
