DESCRIPTION (provided by applicant): The purpose of this study is to identify
the existence and extent of biases associated with HMO full electronic and
claims-type encounter data when they are used to characterize patterns of care
and to analyze the relationship between treatment and outcomes of breast and
cervical cancers. Electronic data assessed will include inpatient and
outpatient visits, pharmacy, cancer registry, pathology, radiology, laboratory,
and electronic physician notes.
This project is a joint venture between four not-for-profit HMOs: Fallon/Meyers
Primary Care Institute, Kaiser Permanente/Northern California, Health Partners
Research Foundation and Henry Ford Health System. A patient who was diagnosed
for breast cancer between January 1, 1996 and December 31, 1997 or for cervical
cancer between January 1, 1996 and December 31, 2000 will be included in the
study. A study central database will be established to contain all electronic
and claims-type encounter data on medical care of these patients. Medical
record information will be abstracted for a random sample of 925 breast cancer
and 995 cervical cancer patients. The study will compare information in the
electronic data sources to information abstracted from medical records, and
assess differences in completeness and accuracy of diagnostic, treatment, and
outcomes by patient characteristics, among HMOs, and by source of data. Using
data abstracted from medical record and electronic data, we will characterize
the patterns of care and assess the relationship between treatment and outcomes
among women of any age with cervical cancer and women age 55 or older with
This study will provide important information about the feasibility of using
computerized claims data as well as other computerized resources for the study
of cancer treatment and outcomes. The primary strength of the study is that it
uses routinely and efficiently collected population based electronic data to
identify cancer patients, treatments and outcomes. If these databases are shown
to be valid, they provide promising resources for cancer studies, with
extensive information on treatment, follow-up and outcome far exceeding those
available from traditional cancer registries.
