The Effect Of Different Method Of Acquiring Informed Consent On The Anxiety In Patients Undergoing Cardiac Interventional Examination Or Therapy

Objective:To make patients undergoing cardiac interventional examination or therapy fill out a questionnaire and visit them to observe the effect of different method of acquiring informed consent on anxiety inr patient undergoing cardiac interventional examination or therapy.Methods:436 clear-eyed patients(231men,205women, mean age 58.2±11.7 years) whose state of an illness allowing them move with basal literacy except the blind and the deaf were selected. They at one time did not suffer from neuropathy and psychosis before. These patients were randomly assigned to receive either a video about procedure of cardiac interventional examination or therapy and detailed informed consent (observation group)or not (control group).The self-rating anxiety scale(SAS) was made out by the patients themselves 2-3 hours before acquiring informed consent and after the cardiac interventional examination or therapy when the patients did not know the state of the illness. Then they would be visit again by telephone after the operation 3 months.Results:Sex, age, stature,weight, smokers, time of be in hospital, medical insurance status, type of cardiac interventional examination or therapy were similar between the two groups.There was also no difference in diabetes, hypertension and hyperlipidemia history between the two groups. Before acquiring informed consent, women scored higher on SAS than men (29.37±5.73 vs 31.18±6.07,P<0.05) and higher than normal standar in China.Effect of age and medical insurance status were not significant;Although there was no significant difference of socre on SAS for different type of heart catheterization,patients undergoing electrophysiology studies and radiofrequency catheter ablation scored highest in the three types. Before informed consent,the scores on SAS was similar between the two groups.After cardiac interventional examination or therapy the score of observation group was lower than control group(0.38±5.65比28.31±4.68,P<0.05),and they were similar too after cardiac interventional examination or therapy 3month. the scores on SAS of control group was significantly lower after cardiac interventional examination or therapy 3month,but observation group was significant lower after cardiac interventional examination or therapy (28.28±5.96 vs 30.10±6.51,P<0.05).Conclusion:anxiety is ubiquitous in patients undergoing cardiac interventional examination or therapy.women should be more cared.After successful cardiac interventional examination or therapy,anxiety in patients would be gradually relieved and an informative video of cardiac interventional examination or therapy and detailed informed consent can better and quickly reduce anxiety in patients undergoing cardiac interventional examination or therapy.
