Prevalence of Depression in pre- and post-operative CABG (Coronary Artery Bypass Graft) patients

Depression in post-surgical patients is a common occurrence. It is likely to occur in cardiac surgery like Coronary Artery Bypass Grafting. This condition could significantly prolong recovery time and could result in complications. Therefore, this study aimed to study the prevalence of Post-Operative Depression amongst Coronary Artery Bypass Graft patients. The undertaken research was conducted amongst patients who had undergone CABG at CMH Lahore and Punjab Institute of Cardiology. A survey was conducted on a sample size of 150 patients, out of which 147 gave consent to participation. The sample size was calculated using WHO Formula. The severity of depression was analyzed through questions in the Becks Depression Inventory. Data was analyzed using SPSS software (25.0 version). Out of 147 patients, 110 were males and 37 were females. The results depicted greater depression amongst females than in males both pre-operatively and post-operatively, with a mean score of 1.41 and 1.08 respectively. A significant difference (p<0.01) was obtained between the correlation of Pre-Operative Scores (in percentages and frequency) and Post-Operative Scores (in percentages and frequency). An insignificant difference (p=0.125) was obtained between the correlation between Preoperative Scores and Gender. A greater Mean Score (1.41) was seen in females, indicating more post-operative depression than males (1.05). An insignificant difference (p=0.239) was obtained between the correlation between Preoperative Scores and Gender. A greater Mean Score (1.08) was seen in females, indicating more post-operative depression than males (0.84). The study concluded that the prevalence of postoperative depression among patients was not significant.
