Introduction:
A patient-reported outcome (PRO) is any outcome reported directly by the patient, in contradistinction to a clinician-reported outcomes, which have dominated clinical research. This systematic review evaluates the ways in which PROs have been used in the interventional radiology literature.
Methods:
Systematic review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and was designed and conducted by a medical librarian. Studies were screened for inclusion by two independent members, with a third member as a conflict resolver. The data were extracted from each study in a consistent and structured manner.
Results:
In all, 354 studies met criteria for full-text analysis; 218 of 354 (62%) used a prospective design and most frequently provided level III (249 of 354, 70%) or level I (68 of 354, 19%) evidence. The manner in which PROs were obtained was reported in 125 of 354 (35%) of studies. Questionnaire response rate was documented in 51 of 354 (14%) studies, and questionnaire completion rate was documented in 49 of 354 (14%) studies. Of 354 studies, 281 (79%) studies used at least one independently validated questionnaire. The disease domains most commonly assessed via PRO were women's health (62 of 354, 18%) and men's health (60 of 354, 17%).
Discussion:
Wider development, validation, and systematic use of PROs in IR would enable more informed patient-centered decision making. A greater focus on PROs in clinical trials would elucidate expected outcomes from the patient's perspective, simplifying comparisons with therapeutic alternatives. To produce more convincing evidence, trials must apply validated PROs rigorously and report possible confounding factors consistently.

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

Patient outcomes reflect the patient's response to the goal rather than what the nurse aims to achieve. Terminology should be observable and measurable to avoid the reader's interpretation. The desired outcome should be realistic and achievable in the designated care timeframe. Expected outcomes should align with adjunctive therapies. The outcome should enhance care...

MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...
