The New Hampshire Uniform Healthcare Facility Discharge Data Set (UHFDDS) is collected under the authority of RSA 126-25 and Administrative Rule He-C 1500. UHFDDS is one of the most useful and complete datasets available to public health officials and health care planners, who use the data for the purposes of assessing hospital utilization and the incidence and burden of disease and injury among New Hampshire residents. Discharge data is released back to the hospitals and to other entities upon request for independent study and analysis.

In 2009, the New Hampshire Department of Health and Human Services (DHHS), Division of Public Health Services (DPHS), in partnership with the Department of Information Technology (DoIT), internalized the dataset after many years of using a vendor. DPHS and DoIT created a new system to receive, process, edit, validate, and store the data received by 32 reporting hospitals in the State of New Hampshire.


All hospitals licensed by the New Hampshire Department under RSA 151:2 are required by law to report patient-level discharge information to the DHHS. Discharges are also collected from select rehabilitation hospitals, rehabilitation and psychiatric units within acute care hospitals, and from free-standing ambulatory surgical treatment centers that are part of a hospital.

Rule Change

In 2010 the NH UHFDDS governing rule He-C 1500 was changed to improve the quality of the data, and expand on the data elements collected. The current rule is based on the UB-04 form, and the new system has been created in accordance with UB-04 definitions, layouts and standards. File submissions are mandated to be in 837i format, which is the standard format used by institutional providers to transmit health care claims electronically. DHHS has worked closely with all reporting hospitals to accommodate the rule change and file formats being submitted.

Accessing NH UHFDDS Data

Data requests should be determined based on two sections in our governing He-C 1500 rule, specifically:

  • He-C 1504.02 Public Use Data Sets
  • He-C 1504.04 Release of Limited Use Facility Discharge Data Sets

All attempts should first be made to utilize the NH HDD Public Use dataset per He-C 1504.02 as opposed to requesting Limited Use data.

The above refers to those who wish to actually obtain a set of discharge data for their own research purposes, where we create a dataset and release it back to you, and Limited Use requests require an application/proposal and data use agreement (DUA) process. The turnaround process for Limited Use applications can take a few months.

Additionally, NH Health Statistics and Data Management (HSDM) is able to provide aggregated datasets based on the individual data needs of the requestor. HSDM staff can analyze data based on your needs and present it back to you in a format that works for you. HSDM is capable of running many complex operations on the data including custom aggregations, spatial joins, and many complex statistical routines. In the right instances, our PhD statistician can perform record level statistical analysis and return the de-identified results to you (e.g., forecasting, regression, CART analysis, mixed models, Bayesian statistics, etc.).
