The development of an archive of patient-reported outcome measures (PROMs) in oncology: The Italian PRO4All project

Abstract

BackgroundChoosing the most adequate measure of patient-reported outcomes (PROs) for a specific medical condition is not straightforward. This study aimed to develop a comprehensive archive of patient-reported outcome measures (PROMs), observer-reported outcome measures (ObsROMs) and caregiver-reported outcome measures (CROMs) in oncology and identify their main characteristics and target outcome domains. Materials and methodsAs part of the Italian PRO4All Project, we retrieved questionnaires through an extensive search of online databases. We developed a data extraction form to collect information on cancer type, questionnaire variant(s), recall period, and scoring system. We performed a content analysis of the questionnaires to assign each item a specific outcome domain according to a predefined 38-item taxonomy. ResultsA total of 386 PROMs (n = 356), ObsROMs (n = 13) and CROMs (n = 17) were identified and described; of these, 358 were also analyzed in their content. 47.3 % of the instruments were cancer type-specific, 45.1 % were generic for cancer and 7.9 % were developed for the general population but also recommended in oncology. The great majority (92.2 %) were patient-reported. In 50.3 % the recall period was “last week”. The mean number of items per questionnaire was 22.0 (range: 1–130). 7794 items were assigned an outcome domain, the most frequent being emotional functioning/wellbeing (22 %), physical functioning (15.7 %), general outcomes (10.1 %) and delivery of care (8.9 %). ConclusionsThere are a variety of patient and caregiver-reported measures in oncology. This archive can guide researchers and practitioners in selecting the most suitable measures and fostering a patient-centered approach in clinical trials, clinical practice, and regulatory activities.
