Introduction: COPD is a worldwide public health issue, while anxiety and depression are highly prevalent comorbidities in COPD, some reviews in overseas reported prevalence rates of up to 75% for anxiety and up to 80% for depression among COPD patients. The situation in Hong Kong is largely unclear and information is lacking.
Objective: To assess the prevalence of anxiety and depression in a regional hospital in Hong Kong and to evaluate the odds ratio of different stages of severity in COPD.
Method: COPD patients before hospital discharge from E3 ward in Princess Margaret Hospital (in-patient) and COPD patients who attend out-patient clinic in block K7 in PMH (out-patient) will be asked for consent to participate in the study. Baseline demographic and clinical information includes staging of COPD, questionnaires of HADS, MMRC, CAT score will be collected by research nurses after consent is obtained.
Result: A total of 260 patients have been approached, with a response rate of 58.08%. 75 in-patients and 76 out-patients were eligible for the study. Our study showed the overall prevalence of depression and anxiety among COPD population are 61.6% and 23.2% respectively. Odds Ratio of depression and anxiety were increased when severity of COPD increased from stage I to IV. Compared with stage I COPD patients, the respective crude odds ratio of depression for stage II is 1.25 (95% CI: 0.15-10.23), stage III is 1.44 (95% CI: 0.19-10.89), while stage IV is 2.09 (95% CI: 0.26-16.86); But in anxiety, the value is insignificant as the odds ratio is less than 1.
Conclusion: This is the first study in Hong Kong which is targeted on estimating the prevalence of depression and anxiety among COPD population and to correlate the finding with the COPD severity. Depression and anxiety are prevalent among the COPD patients as suggested in the study. The possibility of depression increased when severity of COPD stage increases, but the result in anxiety cannot be confirmed. No specific risk factors were found to have statistical significant association with the presence of depression and anxiety, but the current study still warrant attention. Further large scale study may be needed to reveal the situation. A more comprehensive and holistic approach to the COPD patients should be employed to tackle their special need during disease progress, in order to reduce the whole health care system burden. / published_or_final_version / Public Health / Master / Master of Public Health
