Depression After Open Heart Surgery: Influences of Optimism, Sex, and Event-Related Medical Factors

A qualitative study exploring the experiences and needs of fear of disease progression in patients after open-heart surgery

OBJECTIVE

Open-heart surgery (OHS) is a stressful event for patients, all of whom experience varying levels of worry and fear, leading to fear of disease progression (FoP). An in-depth understanding of the experiences and needs of FoP in patients after OHS is beneficial for healthcare providers to make optimal decisions, but this has not been reported. We aimed to explore the experiences and needs of FoP in patients after OHS by adopting a qualitative interview method.

METHODS

A qualitative study was performed to recruit 18 qualified patients through purposive sampling and then conduct face-to-face, semi-structured interviews. The research setting was the cardiovascular surgery ward of a tertiary hospital in Guangdong, China, in 2024. The data were analyzed and extracted using conventional content analysis.

RESULTS

In the study, four themes emerged: a) sources of FoP; b) effects of FoP; c) attitudes towards FoP; d) supportive service needs. The desire to obtain meaningful assistance and the profound experiences of FoP in patients after OHS gave rise to these themes.

CONCLUSIONS

FoP following OHS is a subjective feeling characterized by fear and discomfort. Care workers must completely grasp the patients' fear and provide personalized interventions to support them through the difficult recovery phase, which will also be the focus of future efforts in this area.

Factors predicting depression among persons post-coronary artery bypass graft surgery: A cross-sectional study in Thailand

Background

Coronary artery bypass graft (CABG) surgery is a highly effective coronary artery disease treatment, providing immediate relief and promising long-term benefits. However, it is a major procedure with significant risks, including the potential for depression. Many patients experience depression following CABG, which can negatively impact their overall recovery, affecting both physical and mental health.

Objective

This study aimed to determine factors predicting depression in patients following CABG surgery.

Methods

This cross-sectional study was conducted with data collected between January and April 2024. A total of 272 post-CABG patients from two super tertiary care hospitals in Bangkok, Thailand, were recruited through purposive sampling. All research instruments were validated and tested for reliability. Data were analyzed using multiple regression analysis.

Results

The study found that hope, optimism, illness perception, social support, and anxiety were correlated with depression (adjusted R² = 0.381), but these variables explained only 38.1% of the variance (p <0.05). Among these factors, anxiety (β = 0.311), optimism (β = 0.203), social support (β = -0.117), and illness perception (β = -0.143) were significant predictors (p <0.05), while hope was not a significant predictor. Thus, anxiety emerged as the most crucial predictor of depression in patients who have undergone CABG.

Conclusion

Nurses play a vital role in preventing and managing depression in post-CABG patients. Screening for anxiety and addressing it can prevent depression, enhance social support, and improve outcomes. To develop effective nursing strategies, it is essential for nurses to assess anxiety and implement interventions that promote social support, optimism, and illness perception. These measures can improve care quality, reduce readmission rates, and enhance patients' overall quality of life.

Ketamine for postoperative avoidance of depressive symptoms: the K-PASS feasibility randomised trial

Background

Surgical patients with previous depression frequently experience postoperative depressive symptoms. This study's objective was to determine the feasibility of a placebo-controlled trial testing the impact of a sustained ketamine infusion on postoperative depressive symptoms.

Methods

This single-centre, triple-blind, placebo-controlled randomised clinical trial included adult patients with depression scheduled for inpatient surgery. After surgery, patients were randomly allocated to receive ketamine (0.5 mg kg-1 over 10 min followed by 0.3 mg kg-1 h-1 for 3 h) or an equal volume of normal saline. Depressive symptoms were measured using the Montgomery-Asberg Depression Rating Scale. On post-infusion day 1, participants guessed which intervention they received. Feasibility endpoints included the fraction of patients approached who were randomised, the fraction of randomised patients who completed the study infusion, and the fraction of scheduled depression assessments that were completed.

Results

In total, 32 patients were allocated a treatment, including 31/101 patients approached after a protocol change (31%, 1.5 patients per week). The study infusion was completed without interruption in 30/32 patients (94%). In each group, 7/16 participants correctly guessed which intervention they received. Depression assessments were completed at 170/192 scheduled time points (89%). Between baseline and post-infusion day 4 (pre-specified time point of interest), median depressive symptoms decreased in both groups, with difference-in-differences of -1.00 point (95% confidence interval -3.23 to 1.73) with ketamine compared with placebo. However, the between-group difference did not persist at other time points.

Conclusions

Patient recruitment, medication administration, and clinical outcome measurement appear to be highly feasible, with blinding maintained. A fully powered trial may be warranted.

Pain-related fear among adult patients undergoing open-heart surgery: an interpretative phenomenological analysis

BACKGROUND

One of the sources of anxiety and fear among patients undergoing open-heart surgery is the possibility of experiencing pain, such as sternotomy-related chest pain. Giving them the chance to express their feelings about the potential pain may be effective in reducing their anxiety and may support their coping strategies.

OBJECTIVES

To examine pain-related fear among patients undergoing open-heart surgery and to understand the underlying reasons of their fears.

METHODS

A qualitative interview based on Heidegger's interpretative phenomenological approach was conducted adhering to the COREQ guidelines. Sixteen patients who were undergoing open-heart surgery in the following day were interviewed at the cardiovascular surgery ward of a university hospital. The organization and mapping of the qualitative data was done by using ATLAS.ti 8.0.

RESULTS

The patients who were afraid of experiencing pain after surgery seemed to be more concerned about open-heart surgery itself (such as pain from sternotomy and chest tubes) and the possibility of prolongation of postoperative pain. To cope with these fears, the patients employed a variety of social and self-coping strategies. Trusting the healthcare team, having a high pain tolerance, and having personal thoughts that take precedence over pain-related fear were the key factors explaining not being afraid of experiencing pain.

CONCLUSIONS

This study provides a deeper understanding of the underlying reasons and the needs of patients in controlling their pain-related fears before open-heart surgery. Trusting the healthcare professionals is one of the main factors for patients to control their pain-related fears. To develop a supportive sense of trust and to help patients in controlling their pain-related fears, surgical nurses must dedicate enough time for understanding patients' concerns while planning their nursing care plans. Future studies may focus on exploring the role of nursing interventions and multidisciplinary team approaches on the management of preoperative pain-related fear.

Protocol for the Ketamine for Postoperative Avoidance of Depressive Symptoms (K-PASS) feasibility study: A randomized clinical trial

Background: Postoperative depressive symptoms are associated with pain, readmissions, death, and other undesirable outcomes. Ketamine produces rapid but transient antidepressant effects in the perioperative setting. Longer infusions confer lasting antidepressant activity in patients with treatment-resistant depression, but it is unknown whether a similar approach may produce a lasting antidepressant effect after surgery. This protocol describes a pilot study that will assess the feasibility of conducting a larger scale randomized clinical trial addressing this knowledge gap. Methods: This single-center, double-blind, placebo-controlled pilot trial involves the enrollment of 32 patients aged 18 years or older with a history of depression scheduled for surgery with planned intensive care unit admission. On the first day following surgery and extubation, participants will be randomized to an intravenous eight-hour infusion of either ketamine (0.5 mg kg -1 over 10 minutes followed by a continuous rate of 0.3 mg kg -1 h -1) or an equal volume of normal saline. Depressive symptoms will be quantified using the Montgomery-Asberg Depression Rating Scale preoperatively and serially up to 14 days after the infusion. To detect ketamine-induced changes on overnight sleep architecture, a wireless headband will be used to record electroencephalograms preoperatively, during the study infusion, and after infusion. The primary feasibility endpoints will include the fraction of patients approached who enroll, the fraction of randomized patients who complete the study infusion, and the fraction of randomized patients who complete outcome data collection. Conclusions: This pilot study will evaluate the feasibility of a future large comparative effectiveness trial of ketamine to reduce depressive symptoms in postsurgical patients. Registration: K-PASS is registered on ClinicalTrials.gov: NCT05233566; registered February 10, 2022.
