Maps and Geographical Analysis


CHIA has recently produced several interactive maps of Massachusetts health care data. These maps allow users to better understand variations in health care spending and utilization by displaying recent data on a town-by-town or regional basis.

The Massachusetts Commercial Total Medical Expenses by Town and Region map illustrates geographic variation in spending by commercial health insurers on behalf of their commercial full-claim members in 2014. The map also depicts variation in TME growth from 2013 to 2014 as well as the share of TME by specific service categories.

The Massachusetts Patient Origins map allows users to identify the areas from which Massachusetts hospitals and hospital systems draw their patients by illustrating the distribution of hospital inpatient discharges in 2013 by patient zip code.
