Challenges


Timeliness of Data

The Project attempts to present the most recent information available. However, because the profiles rely upon multiple data sources that collect data on different cycles, this often means that data for different years are presented within a single profile. For example, the health facilities depicted on maps and identified in the Community Health Profiles represent a real-time understanding of existing provider sites. Yet the capacity and utilization data are drawn from the most recent reports available from providers. In some instances, the number of providers that existed at the time for which those data are available is greater or less than the number that exists today.

Accuracy of Data

The data presented in the profiles are primarily a reflection of the information submitted by hospitals, community health centers and other providers to the data sources described above. Thus, if a provider did not report accurately in response to a data request, this will be reflected in the individual hospital or community health profile. Efforts are made to seek explanation for dramatic changes in a provider’s data over time or for data outliers. The providers are the original source of data presented in the profiles.

Rounding Errors

Calculations showing the percent change between two years are based on underlying more accurate data and not on values printed for each year which are rounded. So, for example, the average length of stay when rounded might show the same value, say 4.3, for both years, but since the percent change is calculated on the underlying, more accurate values (say 4.25 and 4.34), the percent change shown will not be 0.

Completeness of Data

In some instances, data submitted by individual providers were incomplete. Missing data are presented in the profiles as Not Available or NA. Additionally, for these preliminary profiles, data were not available for specific classes of providers, including free clinics, hospital-affiliated health centers, and private practice physicians. Efforts are underway to obtain data from these sources. Site-specific staffing data are necessary to calculate capacity for the Community Health Profiles. At this time these data are not available to this project for hospital-based outpatient clinics, hospital-affiliated health centers or school-based health centers.
