Pain as the 5th Vital Sign: Impact on Pain Management at the Portland Veterans Affairs Medical Center

Principal Investigator: Richard Mularski, MD
Co-Investigators: Lois Miller, PhD, RN and Linda Ganzini, MD

Pain is one of the most common reasons people seek medical care and one of the most difficult symptoms for practitioners to evaluate, making accurate pain measurement crucial to proper care. The purpose of this study was to measure improvement in pain measurement and management using the 1999 Veterans Health Administration directive of documenting patients' self report of pain in the vital sign section of medical records. This VA policy established pain as the 5th vital sign for the purpose of prompting practitioners to assess pain comprehensively and initiate intervention strategies if a self-reported pain score warrants such measures, thus improving pain evaluation and management. Compliance with the directive is 95%, but to date there have been no studies that examine the efficacy of the strategy. This project determined the usefulness of the pain as the 5th vital sign strategy for proper pain management and the effect this strategy has on practitioner behavior in terms of assessment, evaluation, and treatment of pain. Medical records were reviewed to obtain data about pain assessment and treatment at clinic visits in the Portland Veterans Affairs Medical Center. The study compared pain assessment and management before and after implementation of the policy to provide an indication whether regarding pain as the 5th vital sign has promoted change in practice behavior and improvements in patient outcomes.
