- Description
- Critical appraisal of research articles can be used to inform the design of new research studies. It can also be used by clinicians who wish to improve service quality by using the best available evidence to inform their practice. This paper describes a broad framework of critical appraisal of published research literature that covers both quantitative and qualitative methodologies. The aim is the heart of a research study. It should be robust, concisely stated and specify a study factor, outcome factor(s) and reference population. Quantitative study designs, including sampling methods, can be ranked in order of the quality of the evidence they produce, with randomised control trials being ranked as level 1. The strength of evidence from qualitative research studies depends on the degree of rigour used in data collection and analysis, using techniques like theoretical sampling, triangulation and participant validation. Whatever the study design, it must be appropriate to address the aim of the study. In critically appraising all research papers, there is a need to reflect on how well the conclusions flow logically from the results of the analysis and answer the original research question and how well the research applies to the population we are interested in.
