Abstract

Methodology of clinical trials is a major determinant to their level of evidenced based medicine. Prospective longitudinal trials such as randomized controlled trials (RCT) have significant position in the hierarchy of evidenced based practice. One of the shortcomings of the RCT could be in the inclusion and exclusion criteria unlike real life settings with clinical decisions made by a psychiatrist due to clinical necessity and not for a protocol necessity or earlier deadlines for data collection. Retrospective analysis gives time to see consistent response over time in real life settings not only six to eight weeks’ response to an antidepressant. Multicenter retrospective analyses by different research groups involving the same antidepressant have the shortcomings of including different cut off points, different inclusion and exclusion criteria or different statistical tools causing challenges in the extrapolation of data. Retrospective interpretation of notes or tools used by different colleagues could be challenging due to interrater reliability issues even with same tool used by different colleagues with different levels of training on/agreement on score allocations for particular patients’ responses. Interpreting what others meant by their notes is another challenge. Questionnaires filled by patients alone in waiting rooms to save time are liable to mistakes and misinterpretations. The aim of this paper is to propose a retrospective naturalistic study to be conducted by the same treating psychiatrist for patients treated with Vortioxetine as a mono/combination therapy for at least a year trying to reduce the interrater errors with the suggested aid in appendixes included.
