OBJECTIVES In 2002, PROQOLID was launched to provide an overview of existing PRO instruments. In October 2011, the term Clinical Outcome Assessments (COAs) was introduced to better reflect the importance of the source of information in measurements: patients (PROs), clinicians (ClinROs), and observers (ObsROs). In May 2013, a new category was added: Performance outcome assessments (PerfOs). With this evolving taxonomy, including information about all COAs might become a crucial step in developing PROQOLID. The objective of this study was: (1) To review how ClinROs are currently reported in PROQOLID; and (2) To propose (if needed) ways of clarifying and updating ClinRO information. METHODS PROQOLID was searched on April 9, 2014 to retrieve current information about ClinROs using an advanced search engine. RESULTS The ClinRO information was found under the category “mode of administration” in the subcategory “clinician-rated.” Out of the 801 questionnaires in the database, fifty-two (6.5%) were identified as ClinROs. Out of these 52 questionnaires, nine were generic. Eight different therapeutic areas were identified (i.e., digestive system diseases, musculoskeletal diseases, neoplasms, nervous system diseases, respiratory tract diseases, psychiatric disorders, pathological conditions signs and symptoms, and skin and connective tissue diseases), representing 17 different indications, and 33.33% of the therapeutic areas included in PROQOLID (n=24). The most represented therapeutic area was psychiatry (n=23) followed by nervous diseases (n=7). Only two questionnaires were specific to children: the Pediatric Evaluation of Disabilty Inventory and the WeeFIM^®
