Can the psro's be cost effective? A study of the effect of the Commonwealth Health Agencies monitoring program on the length of stay of Medicaid patients in Massachusetts.

To analyze the effect of the Commonwealth Health Agencies Monitoring Program on the length of stay of a sample of Massachusetts Medicaid patients, we compared their experience with that of non-Medicaid patients. We found a consistently decreasing trend in the length of stay of Medicaid patients during the 2 1/2-year period studied. The average length of stay of Medicaid patients decreased by 11.

Secular trends of cerebellar gliomas in children.

Temporal changes in the histologic composition of cerebellar gliomas were examined in a population of 132 children operated on between 1927 and 1968 at The Children's Hospital Medical Center of Boston. Linear trends with time were examined for clinical features, histologic features, and tumor types. We found evidence of an increasing occurrence of glioma A and its associated features during the 41-year study period.

Cerebellar gliomas in children.

We studied the relationship of histologic features to survival in a population of 132 children with cerebellar gliomas (excluding medulloblastomas). These children had their initial tumor operation at The Children's Hospital Medical Center of Boston between 1l927 and 1968. A classification system that accentuates differences in survival was derived on the basis of clustering of histologic features and survival.

Histologic features and observational variation in cerebellar gliomas in children.

Variation existed in the recognition of histologic features commonly used in the evaluation of cerebellar gliomas of childhood. Some histologic features (e.g.
