Patient-reported outcomes and digital literacy of patients treated in an oncology day hospital unit.

INTRODUCTION: Patient-reported outcomes (PROs) use, via a computer registry, allows patients to report their symptoms enabling the detection of early signs of progression of the disease. For such a record, the patient needs to show certain skills in new technologies use. The present study aimed to analyse the perception and degree of digital literacy of patients undergoing oncological treatment in an Oncology Day Hospital (ODH). METHODS: A cross-sectional descriptive study was performed, where the degree of literacy of patients attending antineoplastic treatment at the ODH was examined by means of an anonymous survey. RESULTS: A total of 122 patients have been included in the study. The proportion of subjects who use the electronic mail (TM) and the Internet on a daily basis was 45.1% and 70.5%, respectively, and up to 77.9% from the subjects considered that the use of digital 2.0 strategies could help improve communication between healthcare professional and patient.The TM was determined by the age, educational level and employment status of the individual. Furthermore, the age of the patients conditioned their perception of the usefulness of the web 2.0 tools (T2.0). CONCLUSION: This study allowed us to establish a target patient profile to conduct the efficient monitoring of cancer progression by PROs. The results have shown that approximately 60% of the patients in our population could be potential candidates to receive PROs-based health care. This approach enables earlier detection of symptoms and signs of progression and consequently, improves health outcomes for cancer patients.

Extended enzymatic stability of reconstituted lyophilized PEG-asparaginase in vials.

Asparaginase (ASNase) use as a tumour-inhibitor drug has changed completely the natural course of paediatric acute lymphoblastic leukaemia (ALL) in such a way that it represents a paradigm shift in ALL management. ASNase treatment emergence has significantly improved pathologic responses and increased survival rates of ALL patients. Although different ASNase forms are currently available, only the pegylated form (PEG-ASNase) is recommended by relevant clinic guides. PEG-ASNase form shows longer elimination half-life, reducing the number of administrations, along with an enhanced safety profile. In spite of all of these advantages, PEG-ASNase elevated cost limits enormously its use. PEG-ASNase is commercialised as a lyophilised powder which according to the manufacturer it is stable for 24 hours once reconstituted, as a result, the leftover is usually discarded. In this study we analysed the enzymatic stability of reconstituted PEG-ASNase after conservation in three different temperature conditions for 5 and 14 days, aiming to take advantage of the remaining leftover for the subsequent administration. Our results have shown that PEG-ASNase is stable at 4°C, -20°C and -80°C for at least 14 days, retaining the 95% from the initial enzymatic activity in all three storage temperatures. According to our results, it is feasible to reuse the remaining content of PEG-ASNase vial after reconstitution, which means a 50% reduction of its cost for paediatric patient treatment and, consequently, removes the main barrier to use this drug in a wider population.
