Abstract
AIM: During medical procedures, anxiety is a common problem that may lead to decrease in tolerance and increase in stress of patients. It was known that there is an association between information of patients about the intervention and decreased level of anxiety. Here, we aimed to investigate the effect of written informed consent and comprehensive multimedia information on the anxiety level of patients, consumption of sedatives, difficulties during bronchoscopy, complications and duration of procedure.
METHODS: 150 patients undergoing bronchoscopy was included. They were randomized in to two groups (Multimedia information group (MIG) (N=75) and written-informed consent group (WICG) (N=75)). Signed written informed consent was obtained from all patients. Comprehensive multimedia presentation was watched only to MIG. State anxiety scores were evaluated with State-Trait anxiety inventory (STAI-S).
RESULTS: STAI-S score of MIG group (40.31±8.08) was lower than WICG (44.29±9.62) (P=0.007). Satisfaction level was higher in MIG (P=0.001). Higher difficulties during “passage through vocal cords” and “interventions during bronchoscopy” were present in WICG group (P=0.013 and P=0.043, respectively). Midazolam consumption during bronchoscopy, and duration of bronchoscopy was statistically lower in MIG group (P<0.001 and P=0.045, respectively). Difficulties during “waiting period”, “passage through nasal/oral route”, “applications of local anesthesia” and “complication frequency” were similar in both groups.
CONCLUSION: Besides reducing the state anxiety in patients undergoing bronchoscopy, multimedia information can reduce the amount of sedation used, shorten the processing duration and reduce the difficulties during bronchoscopy.
