Importance
A combined objective and subjective wireless monitoring program of patient-centered outcomes can be carried out in patients before and after major abdominal surgery.
Objective
To conduct a proof-of-concept study of a wireless, patient-centered outcomes monitoring program before and after major abdominal cancer surgery.
Design
Patients wore wristband pedometers and completed online patient-reported outcome surveys (symptoms, QOL) 3 to 7 days before surgery, through hospitalization, and for two weeks post-discharge. Alerts were generated for all moderate to severe scores for symptoms and QOL. Surgery-related data was collected via electronic medical chart and complications were calculated using the Clavien-Dindo classification.
Setting
The study was carried out in the inpatient and outpatient surgical oncology unit of one NCI designated comprehensive cancer center.
Participants
Eligible patients were scheduled to undergo curative resection for hepatobiliary and gastrointestinal malignancies, English-speaking, and 18 years or older. Twenty participants were enrolled over 4 months.
Main Outcomes and Measures
Outcomes included 1) adherence with wearing the pedometer; 2) adherence with completing the surveys (MDASI and EQ-5D-5L), and 3) satisfaction with the monitoring program.
Results
Pedometer adherence (88% pre-op versus 83% post-discharge) was higher than survey adherence (75% completed). The median number of steps at day 7 was 1689 (19% of steps at baseline). This correlated with the comprehensive complication index (CCI), for which the median was 15/100 (r = −0.64, p<0.05). Post-discharge overall symptom severity (2.3/10) and symptom interference with activities (3.5/10) were mild. Pain, fatigue, and appetite loss were moderate after surgery (4.4, 4.7, 4.0). QOL scores were lowest at discharge (66.6/100), but improved at week 2 (73.9/100). While patient-reported outcomes returned to baseline at 2 weeks, the number of steps was only one third of pre-operative baseline.
Conclusions and Relevance
Wireless monitoring of combined subjective and objective patient-centered outcomes can be carried out in the surgical oncology setting. Pre- and post-operative patient-centered outcomes have the potential of identifying high risk populations who may need additional interventions to support postoperative functional and symptom recovery.
