Using State Health Compare to Analyze Estimates of Health Care Access, Cost, and Utilization
May 16, 2017:State Health Compare is a new, user-friendly online tool from SHADAC for obtaining and comparing state-level estimates related to health and health care.
How Did SHADAC Generate State-Level NHIS Estimates? |
|||
---|---|---|---|
SHADAC is able to produce state-level estimates from the National Health Interview Survey because our researchers have clearance to access the secure Minnesota Census Research Data Center (MnRDC), which is housed at the Minnesota Population Center at the University of Minnesota. Through the MnRDC, our staff can analyze NHIS microdata that include state identifiers, which are not available in the NHIS public use files. |
This post provides an overview of the state estimates available through State Health Compare for indicators of health care access, affordability and utilization. These indicators, which come from the National Health Interview Survey (NHIS), are available at the state level exclusively through State Health Compare.
Where sample size permits, estimates for the following measures are broken down by age (0–18, 0–64, 19–64, 65+) and coverage type (uninsured, public coverage, private coverage):
-
Access to Care Measures
No Trouble Finding Doctor
Told That Provider Accepts Insurance
Had Usual Source of Medical Care -
Cost of Care Measures
Made Changes to Medical Drugs
Trouble Paying Medical Bills
Needed but Delayed Medical Care
Needed but Did Not Get Medical Care -
Utilization of Care Measures
Had General Doctor or Provider Visit
Had Emergency Department Visit
Spent the Night in a Hospital
Leveraging State Health Compare to Analyze NHIS Indicators
The following examples use the measure ‘Spent the Night in a Hospital’ to show how analysts can use the data and tools provided by State Health Compare to analyze these NHIS indicators to better understand trends in health and healthcare at the national and state levels.
Trend Analyses
State Health Compare allows analysts to examine trends over time while comparing up to seven states at once. Looking at the five year national trend, the share of Americans who reported spending the night in a hospital in the past year has declined, though not substantially, standing at 7.9 percent as of 2015, compared to 8.4 percent in 2011.
Geographic Variation
In addition to national and state averages over time, State Health Compare allows analysts to explore the substantial geographic variation using maps and ranked bar charts. As shown in the map below, on the high end, states as diverse as Hawaii, Oklahoma, North Dakota, Tennessee, Kentucky, Ohio, Rhode Island, Massachusetts, and New Hampshire all had rates of overnight hospitalization between 9.8 percent and 12.4 percent in 2015. On the low end, Washington, California, Nevada, Colorado, Texas, Arkansas, Delaware, Vermont, and Maine all had rates between 4.8 percent and 6.7 percent in 2015.
Demographic Breakdowns
State Health Compare also allows analysts to see how rates of hospitalization and other indicators differ by age or by coverage type at the national and state level (where sample sizes permit). The bar graph below compares rates of hospitalization in 2015 in the U.S., California, and Kentucky broken down by age group. In all three locations, a larger share of individuals 65 years and older report spending a night in the hospital compared with non-elderly populations. Kentucky’s rates of hospitalization among all groups is higher than rates in California or nationally.
State Health Compare also gives analysts the ability to see how rates of hospitalization have changed over time at the national and state level by age or by coverage type. The chart below shows how national rates of hospitalization have changed from 2011 to 2015 by coverage type. The hospitalization rate among those with public coverage was consistently higher than those with private coverage or those who were uninsured. This difference is likely due to the greater rates of hospitalization among elderly Americans (as shown above), most of whom have public Medicare coverage and who make up a large portion of the public coverage group.
As shown, rates of hospitalization have been going down among all three coverage types, though the decline has been the largest for those with public coverage (1.2 percentage-point decline from 2011 to 2015). Hospitalization declined among the uninsured after peaking in 2012, dropping to 4.5 percent in 2015. Rates of hospitalization have remained somewhat steadier among those with private coverage, dropping only 0.6 percentage points between 2011 and 2015.
