Clinical relevance of the first domomedicine platform securing multidrug chronotherapy delivery in metastatic cancer patients at home : the inCASA European project

Background: Telehealth solutions can improve the safety of ambulatory chemotherapy, contributing to the maintenance of patients at their home, hence improving their well-being, all the while reducing health care costs. There is, however, need for a practicable multilevel monitoring solution, encompassing relevant outputs involved in the pathophysiology of chemotherapy-induced toxicity. Domomedicine embraces the delivery of complex care and medical procedures at the patient’s home based on modern technologies, and thus it offers an integrated approach for increasing the safety of cancer patients on chemotherapy. Objective: The objective was to evaluate patient compliance and clinical relevance of a novel integrated multiparametric telemonitoring domomedicine platform in cancer patients receiving multidrug chemotherapy at home. Methods: Self-measured body weight, self-rated symptoms using the 19-item MD Anderson Symptom Inventory (MDASI), and circadian rest-activity rhythm recording with a wrist accelerometer (actigraph) were transmitted daily by patients to a server via the Internet, using a dedicated platform installed at home. Daily body weight changes, individual MDASI scores, and relative percentage of activity in-bed versus out-of-bed (I<O) were computed. Chemotherapy was administered according to the patient medical condition. Compliance was evaluated according to the proportions of (1) patient-days with all data available (full) and (2) patient-days with at least one parameter available (minimal). Acceptability was assessed using the Whole Systems Demonstrator Service User Technology Acceptability Questionnaire. Linear discriminant analysis was used to identify the combination of parameters associated with subsequent unplanned hospitalization. Results: A total of 31 patients (males: 55% [17/31]; World Health Organization Performance Status=0: 29% (9/31); age range: 35-91 years) participated for a median of 58 days (38-313). They received a total of 102 chemotherapy courses (64.7% as outpatients). Overall full compliance was 59.7% (522/874), with at least one data available for 830/874 patient-days (95.0%), during the 30-day per-protocol span. Missing data rates were similar for each parameter. Patients were altogether satisfied with the use of the platform. Ten toxicity-related hospitalizations occurred in 6 patients. The combination of weighted circadian function (actigraphy parameter I<O), body weight change, and MDASI scores predicted for ensuing emergency hospitalization within 3 days, with an accuracy of 94%. Conclusions: Multidimensional daily telemonitoring of body weight, circadian rest-activity rhythm, and patient-reported symptoms was feasible, satisfactory, and clinically relevant in patients on chemotherapy. This domomedicine platform constitutes a unique tool for the further development of safe home-based chemotherapy administration

Home-based e-Health platform for multidimensional telemonitoring of symptoms, body weight, sleep, and circadian activity : relevance for chronomodulated administration of irinotecan, fluorouracil-leucovorin, and oxaliplatin at home—results From a pilot study

Purpose: To assess the impact of chronomodulated irinotecan fluorouracil-leucovorin and oxaliplatin (chronoIFLO4) delivered at home on the daily life of patients with cancer in real time using a home-based e-Health multifunction and multiuser platform. This involved multidimensional telemonitoring of circadian rest-activity rhythm (CircAct), sleep, patient-reported outcome measures, and body weight changes (BWCs). Patients and Methods: Patients received chronoIFLO4 fortnightly at home. Patients completed the 19-item MD Anderson Symptom Inventory on an interactive electronic screen, weighed themselves on a dedicated scale, and continuously wore a wrist accelerometer for CircAct and sleep monitoring. Daily data were securely teletransmitted to a specific server accessible by the hospital team. The clinically relevant CircAct parameter dichotomy index I < O and sleep efficiency (SE) were calculated. The dynamic patterns over time of patient-reported outcome measures, BWC, I < O, and SE informed the oncology team on tolerance in real time. Results: The platform was installed in the home of 11 patients (48 to 72 years of age; 45% men; 27% with performance status = 0), who were instructed on its use on site. They received 26 cycles and provided 5,891 data points of 8,736 expected (67.4%). The most severe MD Anderson Symptom Inventory scores were: interference with work (mean: 5.1 of 10) or general activity (4.9), fatigue (4.9), distress (4.2), and appetite loss (3.6). Mean BWC was −0.9%, and mean SE remained > 82%. CircAct disruption (I < O ≤ 97.5%) was observed in four (15%) cycles before chronoIFLO4 start and in five (19%) cycles at day 14. Conclusion: The patient-centered multidimensional telemonitoring solution implemented here was well accepted by patients receiving multidrug chemotherapy at home. Moreover, it demonstrated that chronoIFLO4 was a safe therapeutic option. Such integrated technology allows the design of innovative management approaches, ultimately improving patients’ experience with chemotherapy, wellbeing, and outcomes
