Study summary

This phase III trial compares a home-based telemonitoring program that collects symptom and daily step information to surgeon only care in improving recovery and stopping complications within 30 days after surgery in patients with gastrointestinal, genitourinary, or gynecologic cancer who are scheduled to undergo abdominal surgery. Patients may experience a decrease in functional capacity and experience symptoms like pain and fatigue after surgery, and this may change their ability to walk and function. Home-based telemonitoring of patient symptoms and their ability to walk and function after surgery may help doctors and nurses find and treat problems early, which may improve the patient's recovery and lower the number of complications after surgery.

Read the detailed description

PRIMARY OBJECTIVES:

I. Compare the impact of remote perioperative telemonitoring care versus surgeon only perioperative care on clinically significant changes in functional recovery (accelerometer daily step count) and related secondary patient-centered outcomes (sleep, sedentary time, symptom severity, symptom interference with daily activities).

II. Compare the impact of remote perioperative telemonitoring care versus surgeon only perioperative care on postoperative complications (Comprehensive Complications Index - CCI) and related secondary surgical outcomes (hospital readmission).

III. Compare early withdrawal (dropout or loss of accelerometer device) between the comparators.

IV. Explore perioperative telemonitoring care-related experiences (acceptability, technology usability, uptake/integration) among patients, families, and surgeons through qualitative focus groups and exit interviews.

OUTLINE: Patients are randomized to 1 of 2 groups.

GROUP I (REMOTE PERIOPERATIVE TELEMONITORING CARE GROUP): Before surgery, patients complete a functional and nutritional assessment. The home environment of patients will also be assessed. Based on findings, patients undergo personalized prehabilitation. Patients also wear an actigraph throughout the study to measure and record daily steps taken and sedentary time. Patients use the TapCloud application (app) on a smart device (phone, tablet) or home computer to collect, track, and report their symptoms. Based on patient input in the TapCloud app, a real-time alert is sent to a registered nurse (RN) when predetermined thresholds are met. RNs then contact the patient via the TapCloud app and further phone calls if necessary. Patients, caregivers and surgeons may also participate in a focus group in-person, via telephone, or videoconferencing.

GROUP II (SURGEON ONLY PERIOPERATIVE CARE GROUP): Patients and their families meet with the surgeon at least once before surgery. After surgery, patients are managed daily during post-operative care. Patients may receive a referral for functional and nutritional prehabilitation at the discretion of the surgeon/surgical team. Patients and their families receive instructions to follow the standard procedures for reporting problems between clinic visits, including contacting their surgical team if symptoms become severe and physical function worsens; and the use of the hospital call line to report problems. Patients, caregivers and surgeons may receive the opportunity to participate in focus group in-person, via telephone, or videoconferencing.

After completion of study, patients are followed up for 3-4 months.

Patients use the TapCloud app on a smart device (phone, tablet) or home computer to collect, track, and report their symptoms.

    Group II (surgeon-only perioperative care program)

    Patients and their families meet with the surgeon at least once before surgery. After surgery, patients are managed daily during post-operative care. Patients may receive a referral for functional and nutritional prehabilitation at the discretion of the surgeon/surgical team. Patients and their families receive instructions to follow the standard procedures for reporting problems between clinic visits, including contacting their surgical team if symptoms become severe and physical function worsens; and the use of the hospital call line to report problems.

What researchers measure

Primary outcomes

  1. Change in Daily Step Count

    Will calculate percent change from preoperative baseline in daily step count during the first 2 weeks post-discharge from hospital. Will use generalized linear mixed modeling (with treatment and covariates as fixed factors, patient identification as random factor).

    Time frame: Baseline up to day 14

  2. Time to Early Withdrawal

    Analyzed using proportional hazards regression.

    Time frame: Up to 4 months

  3. Qualitative Data

    Qualitative data from exit interviews and focus groups will be analyzed using the conventional content analysis approach.

    Time frame: Up to 4 months

  4. Post-operative Complications

    Assessed using the Comprehensive Complications Index (CCI) which summarizes the entire patient postoperative experience with respect to complications (on a scale from 0 to 100), and is based on the established Clavien-Dindo classification. For CCI score: Higher = worse

    Time frame: Up to 30 days after surgery

  5. Maximum CCI

    Maximum CCI will be categorized as above versus below 15, and logistic regression will be used to evaluate the effect of study intervention.

    Time frame: Up to 30 days post-discharge

Secondary outcomes

  1. Time to Hospital Readmission

    Will be subjected to survival analysis.

    Time frame: Up to 90 days post-discharge

  2. Change in Sedentary Time

    Assessed using the Actigraph GT9X Link. Data capture will focus on the following: 1) number of steps taken per day and 2) sedentary time. Recommended activity counts per minute (cpm) cutpoints will be used to categorize sedentary time (\< 100 cpm) from light-intensity physical activity (100-1951 cpm) and moderate/vigorous intensity physical activity (\>=1952 cpm).

    Time frame: Baseline up to 4 months

  3. Change in General Symptoms

    Assessed using the MD Anderson Symptom Inventory.

    Time frame: Baseline up to 4 months

  4. Change in Disease-specific Symptoms

    Assessed using the MD Anderson Symptom Library Items.

    Time frame: Baseline up to 4 months

  5. Change in Sleep

    Assessed using the MD Anderson Symptom Inventory.

    Time frame: Baseline up to 4 months

Participant flow

398 participants were enrolled to the study, however 16 participants did not want to participate after signing consent and are considered attrition which is the reason why data analysis was done for 382 participants instead of the total consented/enrolled.

Adverse events

Collected over Since this is not a drug trial, there was no specific timepoint that was monitored for an adverse event to be recorded. It's an intervention trial that lasts 90 days post-treatment with no blood draws, procedures, etc. Patients were not assessed for specific adverse events however, 4 patients died during the study due to their ongoing cancer diagnosis, not due to study participation. The time frame where each participant was monitored/assessed for death was during the 90 days.. Non-serious events are listed at a 0% frequency threshold.
