CASP - Critical Appraisal Skills Programme


CASP has created short online learning modules so that you can increase confidence when reading research, but in your own time and space. CASP lead trainer, Erica Ison has developed these resources in response to increasing demand for accessible learning modules in a time when critical appraisal skills are more important than ever.

The philosophy of CASP has always been about sharing knowledge and understanding, working in ways that are non-hierarchical, multidisciplinary and using problem-based approaches. This ensures that it is accessible and has practical day to day application.

Everyone wants good health and healthcare that is effective. But how can we know whether a claimed intervention is truly effective? Many interventions are given with the best of intentions but have later been found to be ineffective with the potential for harm and wasted resources.

Critical appraisal skills enable you to systematically assess the trustworthiness, relevance and results of published papers. The Critical Appraisals Skills Programme (CASP) has over 25 years of significant and unrivalled expertise in the delivery of training to healthcare professionals
