IntroductionThere is no unanimous consensus on the clinical features to define breakthrough cancer pain (BTcP). The current project aimed to investigate the opinion of a panel of experts on cancer pain on how to define, diagnose, assess, treat and monitor BTcP.Materials and methodsA two-round Spanish multi-centre exploratory Delphi study was conducted with medical experts (n = 90) previously selected from Medical Oncology Services, Radiation Oncology, Palliative Care/Home Care Teams, and Pain Units. The study intended to seek experts’ consensus and to define a set of recommendations for the management of BTcP.ResultsIt was generally agreed that, definition of BTcP implies that baseline pain should be controlled (84 %), although not necessarily with opioids (only 30 %); there must be exacerbations (98.9 %); the duration of each episode should last <1 h (70 %); the intensity of pain ≥7 out of 10 (67.8 %); and the number of flares per day should not be less than four. All participants supported the use of the Davies algorithm for the diagnosis. The use of a ‘Patient Diary’ was highly recommended. The optimal treatment should have a rapid onset, a short-acting analgesic effect (1–2 h) and transmucosal nasal or oral administration. It was considered very important to develop protocols for the management of cancer pain.ConclusionsThe present Delphi study identified a set of recommendations to define, assess and monitor BTcP.

Background Breakthrough pain is a major problem and a source of distress in patients with cancer. We hypothesized that health care professionals may benefit from a real-time mobile app to assist in the diagnosis and monitoring of breakthrough cancer pain (BTcP). Objective This study aimed to test the usability, acceptability, and usefulness in real-world practice of the mobile App INES·DIO developed for the management of patients with BTcP. Methods This study consisted of a survey of a multidisciplinary sample of 175 physicians who evaluated the mobile app after testing it with 4 patients with BTcP each (for a total of 700 patients). The digital profile of the physicians, use of the different resources contained in the app, usefulness of the resources, acceptability, usability, potential improvements, intention to use, and additional resources to add were recorded. Results Of the 175 physicians, 96% (168/175) were working in public hospitals. They had an average of 12 (SD 7) years of experience in BTcP and almost all (174/175, 99.43%) had an active digital profile. The Eastern Cooperative Oncology Group and Karnofsky performance scales, the Visual Analogue Scale, and the Davies algorithm to diagnose BTcP were the most frequently used tools with patients and were assessed as very useful by more than 80% (140/175) of physicians. The majority (157/175, 90%) answered that App INES·DIO was well designed and 94% (165/175) would probably or very probably recommend it to other colleagues. More than two-thirds indicated that the report provided by the app was worth being included in patients’ clinical records. The most valued resource in the app was the recording of the number, duration, and intensity of pain flares each day and baseline pain control to enhance diagnosis of BTcP. Additional patient-oriented cancer pain educational content was suggested for inclusion in future versions of App INES·DIO. Conclusions Our study showed that App INES·DIO is easy to use and useful for physicians to help diagnose and monitor breakthrough pain in patients with cancer. Participants suggested the implementation of additional educational content about breakthrough pain. They agreed on the importance of adding new clinical guidelines/protocols for the management of BTcP, improving their communication skills with patients, and introducing an evidence-based video platform that gathers new educational material on BTcP.
