2009 Kearney et al. United Kingdom | To evaluate the impact of a mobile phone-based remote monitoring, advanced symptom management system (ASyMS©) on the incidence, severity and distress of six chemotherapy-related symptoms in patients with lung, breast, or colorectal cancer. | n = 112 (56 in each intervention or control group) patients from 7 clinical sites throughout the UK. Inclusion criteria: commencing a new course of chemotherapy treatment, receiving outpatient chemotherapy, age ≥ 18, written informed consent given, able to read and write English, and deemed by members of the clinical team as being physically and psychologically fit to participate in the study. | Chemotherapy related toxicity in patients with lung, breast, or colorectal cancer | • Severity and distress of the six symptoms including vomiting, nausea, diarrhea, hand-foot syndrome, sore mouth/throat, and fatigue. • Incidence – (did symptom occur? Y/N), Severity and distress (scores 0–3) of the six individual symptoms. • ASyMS has integrated the Common Toxicity Criteria Adverse Events (CTCAE) grading system and the Chemotherapy Symptom Assessment Scale. • Paper version of the electronic symptom questionnaire was administrated at baseline, chemotherapy cycles 2, 3, 4, and 5 in both groups. | • Two of the six symptoms measured (fatigue and hand-foot syndrome) showed statistical significance between the control and intervention groups (respectively, p = 0.040, p = 0.031). • Patients reported improved communication with health professionals, improvements in the management of their symptoms, and feeling reassured their symptoms were being monitored while at home when using ASyMS. |
