among staff nurses. One–group pre–test and post–test methods of pre–experimental design were taken. The samples for the study were chosen by

non–probability purposive sampling. 30 clinical nurses were selected as sample based on the selection criteria. A structured interview schedule and

observational checklist was developed based on review of literature and opinion from experts. Level of knowledge was studied in relation to

various aspects like knowledge on anatomy & physiology, aetiology, risk assessment and preventive management. Data were collected from

clinical nurses who were working at 200 bedded Cardiac speciality Hospital. The findings of the study were: The existing level of knowledge on

clinical nurses was inadequate 20(66.7%) and the existing practice level was inadequate among 14(46.7 %) clinical nurses. Exposure to the

structured teaching programme and emphasising the usage of Wells Score increased the knowledge (‘t‘ value 10.62) and practice level (‘t‘ value

13.24) among clinical nurses. Some of the selected background factors like years of experience and previous exposure to DVT class were not

associated whereas level of education ( B.Sc. and G.N.M.) was associated with knowledge and practice level among clinical nurses regarding

Deep Vein Thrombosis. Thus, the study concluded that effective teaching programme can improve both knowledge and practice level of clinical

nurses. A similar study could be undertaken on a larger scale for making a more valid generalization
