60 HOSPITALS/SYSTEMS DIGEST 2013 SANOFI / MANAGED CARE DIGEST SERIES® / WHERE INFORMATION BECOMES INTELLIGENCE.™
RESEARCH METHODOLOGY
RESEARCH METHODOLOGY
HMOs, Hospitals, Medical Group Practices
HMO and hospital utilization data, gathered
from state health licensing agencies, federal
government sources and telephone or email
surveys, are effective as of December 31, 2011.
Integrated systems, identified using local and
national periodicals, trade publications and
provider contacts, were contacted by phone
to verify data. These data were gathered during
2012 and are effective as of July 2012.
IMS Health also provided national data about
medical group practices with five or more full-time
equivalent physicians, totaling nearly 13,000
medical group practices nationwide. Data are
effective as of July 2012.
Hospital Inpatient and Outpatient
The IMS Health Hospital Procedure/Diagnosis
(HPD) database contains an extensive set of
hospital inpatient and outpatient discharge
records, including actual diagnoses and
procedures data for about 75% of all
discharges nationwide (including 100% of
Medicare-reimbursed discharges). The HPD
database reports the numbers of procedures
performed on patients discharged from
a hospital. Most states report at least nine
diagnostic and six procedure codes from each
discharge record. IMS Health uses Medicare
procedure counts and additional hospital-level
information to estimate procedure counts for the
remaining 25% of discharges—the non-Medicare
hospital discharge information in nonreporting
states. The hospital inpatient and outpatient
data provided in this Digest are current as of
calendar year 2011. See the table on page 61
for a list of common disease states tracked.
