Patient-reported outcomes in cancer patients admitted during the COVID 19 pandemic in a tertiary Spanish hospital.

e24098 Background: Patient reported outcomes measures (PROMs) represent a tool to objectively assess the health of cancer patients. PROMs may complement oncological evaluations by adding patients’ perspectives on their care priorities. Aim: to address more accurately the management of tumor related symptoms or drug related toxicities to bring he therapies more accurately to bring patients the best quality of life possible. Methods: Data was collected from our electronic registry after proper authorization and corresponding anonymization. Patients were systematically asked for symptoms as fever, diarrhea, dyspnea, vomiting and nausea. These symptoms were graded according to their severity using the Common Toxicity Criteria v5.0. Results: 49 patients admitted to Medical Oncology Hospitalization were included from July of 2020 to January 2021, 80% in advanced disease. Median age 63yo, 32% above 70 yo. Baseline data showed that 27% patients (19% stage IV) had fever at admission, decreasing at 48h to 4%. Patients who had vomiting at admission were 33% (28% stage IV) median grade 2 becoming 20% and grade 1 at 48h. Nausea was present in 49% patients (35% stage IV) at the time of admission with a median grade 1.5, and it decreased to 16% at 48h with a median grade 2. Diarrhea was reported in 12% patients (6% stage IV) median grade 2 at baseline and it was reduced to 10% median grade 1 at 48h. The median severity of diarrhea at admission was 2 and only 1 at 48h. At admission, 33% (all stage IV) of patients presented dyspnea with a median grade 3, while at 48h it was present in 26% of patients and reduced to median grade 2. Conclusions: By systematically measuring symptoms, patients achieved better control of diarrhea, dyspnea, vomiting and nausea after admission. It should be noted that nausea was the variable that decreased the most at 48h, followed by fever, vomiting, dyspnea and diarrhea. All patients with stage IV disease had dyspnea and most of them had nausea and vomiting. These results reflect that these symptoms are more usual in patients with advanced disease compared to those with localized disease. PROMS also help us educate patients by teaching them how to manage treatments, thus improving therapeutic adherence.
