Background
Survivors of intensive care unit (ICU) admissions frequently experience psychological distress, with anxiety and depression being particularly prevalent. While the Hospital Anxiety and Depression Scale (HADS) is a commonly used instrument for assessing these conditions, there is limited evidence comparing its effectiveness with simpler tools like the Visual Analogue Scale (VAS) in ICU settings.
Objective
The objective of this study was to compare the accuracy of the VAS with the HADS for screening anxiety and depression in ICU patients.
Methods
A prospective, single-centre observational cohort study was conducted in a tertiary ICU. Adult patients with an ICU length of stay exceeding 48 h were enrolled. Anxiety and depression symptoms were self-reported using both the VAS (0–10 scale) for pre-ICU and ICU stay and HADS (0–21 scale). Borderline and probable anxiety/depression were defined by HADS scores ≥8 and ≥ 11, respectively. Paired t-tests compared VAS scores before and during ICU stay. Receiver operating characteristic curve analysis assessed the accuracy of the VAS against that of the HADS, with optimal cut-off values determined using the nearest method and bootstrapped confidence intervals.
Results
Of 135 participants (response rate: 93.8%, mean age: 63 ± 16 years; 42% female, median Acute physiology and Chronic Health Evaluation II score: 15), 48.2% and 47.4% met criteria for anxiety and depression, respectively. No significant differences were observed in pre-ICU versus in-ICU VAS scores. The area under the receiver operating characteristic curve for in-ICU VAS was 0.77 and 0.79 for borderline and probable anxiety and 0.73 and 0.76 for borderline and probable depression, respectively. Optimal VAS cut-offs were 4 and 3 for borderline and probable anxiety and 4 and 2 for borderline and probable depression, respectively.
Conclusion
The VAS demonstrated acceptable discriminatory capability compared to the HADS and may serve as a rapid, effective screening tool for anxiety and depression in ICU patients. Given the high prevalence of these conditions, further research is warranted to validate these findings and explore clinical integration.
