About the List of High Risk Operations for Patients Over Age 65
Previous studies have resulted in a lack of consensus regarding high-risk surgical procedures in older adults.
In a recent study using claims data and a modified Delphi procedure, the authors of this toolkit created an inclusive, precise definition of high-risk surgeries that can be used by clinicians, researchers, hospitals, and patients to support the creation of targeted interventions, quality and outcomes research, and informed decision-making.
What does the toolkit contain?
This toolkit contains an Excel file that you can download and then import into your statistical program.
The file contains a list of 227 surgical procedures, which are identified by International Classification of Disease, Ninth Revision, Clinical Modification (ICD-9-CM) procedure codes and mapped to modified Healthcare Cost and Utilization Project (HCUP) Clinical Classifications Software (CCS) groups.
Who should use this toolkit?
This toolkit is intended for researchers who are interested in conducting quality and outcomes research studies that incorporate the list of high-risk surgeries for older patients.
It can also be used by clinicians, researchers, and health care administrators who are interested in designing targeted clinical interventions for high-risk surgical procedures.
The List of High Risk Operations for Patients Over Age 65 was developed by researchers and clinicians (Principal Investigator: Margaret Schwarze) at the University of Wisconsin-Madison School of Medicine & Public Health – Department of Surgery.
This project was supported by University of Wisconsin Institute for Clinical and Translational Research (UW ICTR), grant 9 U54 TR000021 from the National Center for Advancing Translational Sciences (previously grant 1 UL1 RR025011 from the National Center for Research Resources), the University of Wisconsin School of Medicine and Public Health’s Health Innovation Program (HIP), and the Wisconsin Partnership Program. Dr. Schwarze is supported by the Greenwall Faculty Scholars Program, and Dr. Barnato is supported by grant R01 AG035112 from the National Institutes of Health.

The methodology used to develop this list, along with the associated rates of mortality, confidence intervals, and p-values associated with each operation, is available in the following article: Schwarze ML, et al. “Development of a list of high-risk operations for patients 65 years and older.” JAMA Surg 2015;150(4):325-31.
