UNC Study: Cancer Patient Symptom Surveys Linked To Reduced Emergency Visits, Improved Survival and Quality of Life

Systematic collection of cancer patients’ symptoms using computer surveys was linked to less frequent emergency room (ER) admissions, longer average chemotherapy adherence, greater quality of life improvements, and improved survival, according to a new randomized, controlled trial spearheaded by a researcher at The University of North Carolina at Chapel Hill.

The first-in-kind study, led by Dr. Ethan Basch, associate professor of health policy and management at UNC’s Gillings School of Global Public Health and member of the UNC Lineberger Comprehensive Cancer Center, was published online December 7 in the Journal of Clinical Oncology. The study compared outcomes for cancer patients at the Memorial Sloan Kettering Cancer Center (MSKCC) in New York, who reported their symptoms using a Web-based survey system, with outcomes for patients who relied on usual care for symptom detection. The study evaluated outcomes for 766 patients at MSKCC with metastatic cancers who were receiving outpatient chemotherapy.

Dr. Basch, who also is associate professor of hematology and oncology in the UNC School of Medicine and director of UNC Lineberger’s Cancer Outcomes Research Program, led the study at MSKCC before his move to UNC in 2012.

For patients using the Web system, automatic email alerts were sent to nurses and doctors for severe or worsening symptoms. Prior research has shown that doctors miss up to half of patients’ symptoms during cancer treatment. Researchers say survey systems like this one can effectively inform clinicians about issues of concern.

“If we had developed a new drug that yielded these kinds of benefits, we would be very excited,” Dr. Basch said. “This randomized trial found that integrating systematic collection of patient symptoms via the web into cancer treatment improves multiple key clinical outcomes.”

A larger number of patients using the survey system experienced quality of life improvements, with improvements in 34 percent of patients, compared to 18 percent of patients receiving usual care. The survey group also had fewer emergency room visits, with 34 percent visiting the ER compared to 41 percent receiving usual care. They remained on chemotherapy longer at an average of 8.2 months, compared to 6.3 months. They also saw survival benefits – 75 percent of patients using the surveys were alive after one year, compared to 69 percent of those receiving usual care.

“While this study wasn’t designed to evaluate the mechanism of why we saw these improvements, we can hypothesize that by flagging symptoms that clinicians would otherwise miss, we enable earlier symptom management that avoids downstream events like pain crisis, dehydration or intractable nausea,” said Dr. Basch. “I would suspect that the main mechanism of action is improved awareness by clinicians of patient symptoms, which enables earlier interventions to avert downstream, untoward events.”

Dr. Basch noted the computer survey system improved symptom management activities. The study found that nurses directly acted upon the system results more than three-quarters of the time, with changes in medication resulting from 12 percent of email alerts, and referrals to the emergency room occurring due to 8 percent of alerts.

“Direct patient reporting gives patients a voice – their unfiltered experience is captured and conveyed to their health care providers, and their perspective is not being modified by a clinician or anybody else,” Dr. Basch said.
