The main issues examined in this work are: selection of specific areas of enhancing the quality of clinical trials, demonstration of planning and design process of a clinical trial by participating in a NHS based clinical research and finally recommendations for an optimum standard for evaluation of medical devices for this patient group. The various ways in which clinical trials can be conducted along with the strengths and limitations of different types of clinical trials are critically analysed. The contextual factors such as patient compliance with treatment, professional practice of adopting research-based evidence and patients'' perspectives influencing the treatment of venous leg ulcers are critically examined.
