PtDAs improve patient knowledge of the health condition, options, and outcomes. We created a novel PtDA prototype to improve the quality of decisions made by patients when deciding between TMT and RC with ileal conduit. Acceptability and effectiveness testing will be performed prospectively with uro-oncologists, medical and radiation oncologists, and patients.

Purpose or Objective We aimed to analyse whether the corona pandemy caused changes in the distribution of the numbers of patients treated by radiotherapy taking into account the primary diagnoses of the patients over time. Materials and Methods The analysis was conducted from 2017 to 2021 to compare three pre-pandemy years with two years during the pandemy. The departmental radiation oncology information system, ARIA (Varian®), was searched for patient numbers in combination with the diagnosis of the radiation treatment courses. Additionally, the list of appointments was screened for an analysis of the numbers of patients assigned to radiation oncology. Coding of primary disease was performed with the WHO medical classification list ‘International Classification of Diseases Version 10’ (ICD-10). The following questions were addressed: (1) monthly assignment of patients to the department, (2) yearly number of treated patiens by ICD-10 from 2017 through 2021, (3) the ratio of patients treated with radiotherapy and the patients assigned to the department by treatment years. Results The numbers of patients assigned to radiotherapy were significantly reduced during the time of the strict lockdown during April and May 2022. However, the number of citations quickly returned to the baseline level after the end of the lockdown. There is a continuous trend of an increasing number of patients assigned for radiotherapy between January 2018 and December 2021 with an increase from 280 patients per month to 330 patients per month on average. The ratio of patients who received radiotherapy and the patients assigned to the department was at a median of 0.785 (range 0.77 – 0.81) without a trend over time (0.79, 0.78, 0.81, 0.77 in 2018, 2019, 2020 and 2021, respectively). Analysis of the ICD-10 codes over time showed significant changes only for patients with prostate cancer and a trend for breast cancer, both increasing in 2020 and 2021 compared to prior to the pandemy years. This is illustrated by the graphs in Figure 1 showing primay diagnoses by ICD-10 from 2017 to 2021. The age distribution of men treated with radiotherapy for prostate cancer did not change over time (median 72,08; range 71.69 – 72.54 years old).
