| description | Patients should not suffer needless anxiety before surgery. This study was
aimed to determine the level of anxiety that exist in patients undergoing elective
surgical procedure from various departments. Comparison was also made within the
various demographical data obtained with specific objective.
Methods: This was a prospective randomized, double blind controlled clinical trial on
preoperative anxiety levels. Patients completed the anxiety assessment scales both
before and after intervention. The scale used was Hospital Anxiety and Depression
Scale(HADS) The fourteen questions were subdivided to assess anxiety and
depression separately. Paired T-test within groups and independent T-test for between
groups were used during statistical analysis using SPSS 11.0. A p < 0.05 was
considered to be significant.
Results: One hundred and forty scale sets were obtained with no statistically
significant difference in demographic characteristic. The interventional group had preintervention
mean anxiety score of 8.3 ± 2.3 (mean± SD) and post- intervention mean
anxiety score of 3.3 ± 1.8 with p = 0.000 where the placebo group had preintervention
score of 8.9 ± 2.3 and post-intervention score of 10.24 ± 2.9 with p =
0.001. Differences were also seen in mean anxiety score with ethnicity, gender, ASA
class (American Society of Anesthesiologist) and type of operation.

Conclusion: In this study, it was found that significant level of anxiety existed
preoperatively and premedication reduced it's level significantly. The placebo group
had the highest level of anxiety and its level increased even more immediately before
surgery. In addition, female patient, ASA II and patients undergoing gynaecological
surgery had higher level of anxiety. |
