Absolom et al.33 Outpatient, tertiary care providing chemotherapy Prospective, randomised two-arm parallel group study Patients initiating systemic treatment (chemotherapy with or without targeted therapies) for colorectal, breast, or gynaecological cancers. eRAPID was added to usual care. Participants completed online symptom questions from home over 18 weeks (at least weekly plus when having symptoms). Reminders were sent weekly via text or e-mail. (n = 256) Patients were regularly assessed by oncologists or nurses in clinics or by telephone for toxicity and to prescribe next treatment. Patients contacted the hospital via a 24/7 emergency hotline. (n = 252) (a) Symptom control at 6, 12, and 18 weeks after baseline.(b) Impacts on hospital services (process of care measures) Participants received immediate advice on symptom management or a prompt to contact the hospital. The symptom reports were displayed in real time in EPR. Nurses monitored email alerts for severe symptoms. • Based on FACT-PWB scores, positive effects of eRAPID were observed at 6 (p = 0.028) and 12 weeks (p = 0.039), but there was no significant difference at the primary end point of 18 weeks (p = 0.69)
• No between-arm differences were found for chemotherapy delivery, hospital admissions, acute oncology assessments, or emergency hotline calls

de Thurah et al.31 Outpatient, Denmark Pragmatic noninferiority RCT at two centres. Rheumatoid arthritis AmbuFlex ePRO system used as a decision aid in deciding whether patients required an outpatient appointment. The 11-item Flare-RA was used.Arm 1: Follow up by a rheumatologist (PRO-TR) (n = 93)Arm 2: Follow up by a nurse (PRO-TN) (n = 88) Physicians saw patients in the outpatient clinic every 3–4 months. (n = 94) Change in DAS28 after week 52. Patients in the AmbuFlex groups were seen in outpatient clinic if their Flare-RA score was ⩾2.5 and/or their C-reactive protein (CRP) level was ⩾10 mg/litre. • Noninferiority was established for the DAS28 in both AmbuFlex groups when compared with usual care. In the ITT analysis:
• Mean differences in the DAS28 score between PRO-TR versus usual care = −0.10 ([90% CI]:−0.30, 0.13)
• Between PRO-TN versus usual care = -0.19 (90% CI: -0.41, 0.02).
• Including 1 yearly visit to the outpatient clinic patients in:
• PRO-TN: 1.72 ± 1.03 visits/year
• PRO-TR: 1.75 ± 1.03 visits/year
• Usual care: 4.15 ± 1.0 visits/year.
Fjell et al.37 Outpatient, Sweden non-blinded RCT at two centres Patients with breast cancer undergoing neoadjuvant chemotherapy. The Interactive ‘Interaktor’ ePRO application for symptom reporting, self-care advice and symptom management during neoadjuvant chemotherapy. Utilised 14 questions. Email reminders were sent. (n = 74) (i) Outpatient visits before each chemotherapy treatment(ii) A visit where the treatment, related symptoms and how to manage them were discussed.(iii) Contact number for a nurse for treatment related concerns (n = 75) Symptom burden two weeks after completing chemotherapy Patients had continuous access to evidence-based self-care advice and relevant websites. An alert triggered a notification suggesting to the patient related self-care advice. An alert also initiates a phone call from a nurse. Using the MSAS questionnaire, Interaktor group had:
• Lower prevalence of nausea (p = 0.041), vomiting (p = 0.037), and feelings of sadness (p = 0.003)
• Less overall symptom distress (p = 0.004), and physical symptom distress (p = 0.031).
• Lower scores in the total MSAS (p = 0.033). Effect size = 0.26– 0.34.Using the EORTC QLQ-C30, Interaktor group had: Higher emotional functioning (p = 0.008)

Not applicable (i) Track illness(ii) Offer support(iii) Identify worsening patients The programme used text message reminders, and telephone-based care. Members of the medical team evaluated symptom severity, provided information, and referred patients with severe symptoms to the ED. • Of those who filled out a questionnaire, on any given day, about 20% reported concerning symptoms.
• An average of 9 patients per day went to the ED (SD: 5; range: 1–21)
Kroenke et al.40 Outpatient, US Multicentre, RCT Patients screened positive for at least one SPADE (sleep, pain, anxiety, depression, and low energy/fatigue) symptom (their underlying chronic conditions were unspecified) Participants electronically completed the PROMIS profile-29. Feedback of their symptom scores were provided to clinicians. (n = 150) Participants also electronically completed the PROMIS profile-29. No feedback was provided to clinicians (n = 150) (i) 3-month change in composite SPADE score Clinicians received symptom scores for patients in the feedback group • Non-significant trend favouring the feedback compared with control group (between-group difference in composite T-score improvement, 1.1; p = 0.17).
Mooney et al.41 Outpatient, US Multicentre, RCT Patients starting chemotherapy (underlying diagnosis unspecified). Patients in the Symptom Care at Home (SCH) arm called the automate system daily to report symptom severity. They received self-management coaching. Alerts of poorly controlled symptoms were sent to nurses who intervened following a decision support guidance. (n = 180) Patients also called the automate system daily to report symptom severity daily but did not receive any further interventions (n = 178) • Symptom severity across all symptoms
• Number of severe, moderate symptom days
• Individual symptom severity
Patients in the SCH arm received self-management coaching. Alerts of poorly controlled symptoms were sent to nurses who intervened following a decision support guidance. • Symptom severity across all symptoms was significantly less among SCH participants (p < 0.001).
• Average reduction of symptom severity for SCH arm was 3.59 points (p < 0.001), roughly 43% of usual care.
• SCH arm had significant reductions in severe (67% less) and moderate (39% less) symptom days compared with usual care (both p < 0.001).
• All individual symptoms, (except diarrhoea), were significantly lower in the SCH arm (p < 0.05).
Nipp et al.32 Inpatient setting, US Single centre, non-blinded, pilot RCT Patients with advanced cancers who have unplanned hospital admissions The IMPROVED monitoring system was used by participants to report daily symptoms. (n = 75) Participants also reported their symptoms each day using tablet computers. Clinicians did not receive their symptom reports. (n = 75) Preliminary efficacy of IMPROVED for: (i) Improving symptom burden(ii) Health care utilisation among hospitalised patients with advanced cancer. The oncology team received the symptom reports for patients on IMPROVED and discussed these during morning rounds. Responses to the ePRO data were based on clinical judgement. • Patients assigned to IMPROVED had a greater proportion of days with lower psychological distress: 0.12 (95% CI, 0.03– 0.21; p = 0.008).
• Patients assigned to IMPROVED experienced improvements in their average symptom scores for drowsiness (B = −0.54, 95% CI: −1.04 to −0.05; p = 0.033) and shortness of breath (B = −0.43, 95% CI: −0.75 to −0.11; p = 0.009), but not for other individual physical symptoms.
• No significant intervention effects on patients’ hospital length of stay.
Nipp et al.42 Outpatient, US Secondary analysis of data from the STAR RCT by Basch et al. Advanced solid tumours - metastatic breast, genitourinary, gynaecologic, or lung cancers STAR system. Symptoms discussed during clinic. Patients encouraged to telephone between visits for concerning symptoms. To explore the moderating effects of age on the outcomes of the STAR RCT namely: Nursing response to alerts: (i) telephone for symptom management counselling(ii) medication initiation/change (iii) referrals
(iv) chemotherapy dose modification
(v) imaging/test orders(i) Survival(ii) ER visits(iii) Hospitalisation
• Younger patients (median age = 58 years) on STAR experienced lower risk of ER visits (HR = 0.74, P = 0.011) and improved survival (HR = 0.76, P = 0.011) compared with younger patients on usual care.

• Older patients (median age = 75 years) did not experience significantly lower risk of ER visits (HR = 0.90, P = 0.613) or improved survival (HR = 1.06, P = 0.753) with the intervention.

• There were no moderation effects based on age for HRQOL
• and risk of hospitalisation.
Rasschaert et al.43 Outpatient, Belgium Multi-centre, prospective cohort Patients with solid tumours (Gastro-intestinal, genito-urinary, breast, ling, head and neck, melanoma, gynae) receiving systemic antineoplastic agent(s) at any stage of their disease. AMTRA was used for daily symptom reporting. Questions were drawn from PRO-CTCAE. A compliance tool to monitor oral therapies was incorporated in the system. Reminders were sent. (n = 168) There was no control arm. Usual care included consultation with an oncologist during systemic treatment.Patients were provided information on treatment, toxicities and instructions on contacting the hospital for serious AEs. Effect on:(i) symptom burden(ii) medication compliance Staff received detailed training on the system and pathways generated by alerts. For toxicities graded as 1 or 2, self-management information was provided. For severe AE’s, medical staff received emailed alerts, contacted patients to advise or refer to the hospital. • A reduction of mean grade over time for five toxicities (nausea, constipation, loss of appetite, fatigue, and dyspnea), (p < 0.0001).
• Compliance to oral chemotherapy was high using AMTRA, median = 98.7% (95% CI: 93.5–100.0%).
Schougaard et al.27 Outpatient, Denmark Multi-centre, observational implementation study Patients with epilepsy, coronary heart disease, narcolepsy, sleep apnoea, prostate cancer, asthma, rheumatoid arthritis, colorectal cancer, and renal failure AmbuFlex system, where the patients’ ePROs determined the need of an outpatient consultation. Items were ad hoc.Reminders were sent. Not relevant as system has been implemented for routine use Impact on utilisation of resources in epilepsy and sleep apnoea clinics A traffic light alert system was developed.A clinician has to decide whether further contact is needed.Red: Definite need of contact or the patient asks for a consultation. • Of 8256 telePRO-based contacts from epilepsy outpatients, up to 48% were handled without further contact.
• For sleep apnoea up to 57% of the 1424 telePRO-based contacts did not require further contact.
• Completion rates were over 90% at baseline and follow up.
