Quality of Life Is Improved 1 Year After Cardiac Surgery

A conversational agent for enhanced Self-Management after cardiothoracic surgery

BACKGROUND

Enhanced self-management is crucial for long-term survival following cardiothoracic surgery.

OBJECTIVES

This study aimed to develop a conversational agent to enhance patient self-management after cardiothoracic surgery.

METHODOLOGY

The solution was designed and implemented following the Design Science Research Methodology. A pilot study was conducted at the hospital to assess the feasibility, usability, and perceived effectiveness of the solution. Feedback was gathered to inform further interactions. Additionally, a focus group with clinicians was conducted to evaluate the acceptability of the solution, integrating insights from the pilot study.

RESULTS

The conversational agent, implemented using a rule-based model, was successfully tested with patients in the cardiothoracic surgery unit (n = 4). Patients received one month of text messages reinforcing clinical team recommendations on a healthy diet and regular physical activity. The system received a high usability score, and two patients suggested adding a feature to answer user prompts for future improvements. The focus group feedback indicated that while the solution met the initial requirements, further testing with a larger patient cohort is necessary to establish personalized profiles. Moreover, clinicians recommended that future iterations prioritize enhanced personalization and interoperability with other hospital platforms. Additionally, while the use of artificial generative intelligence was seen as relevant for content personalization, clinicians expressed concerns regarding content safety, highlighting the necessity for rigorous testing.

CONCLUSIONS

This study marks a significant step towards enhancing post-cardiothoracic surgery care through conversational agents. The integration of a diversity of stakeholder knowledge enriches the solution, grants ownership and ensures its sustainability. Future research should focus on automating message generation and delivery based on patient data and environmental factors. While the integration of artificial generative intelligence holds promise for enhancing patient interaction, ensuring the safety of its content is essential.

A Three-Day Prehabilitation Program is Cost-Effective for Preventing Pulmonary Complications after Heart Valve Surgery: A Health Economic Analysis of a Randomized Trial

Background

While prehabilitation (pre surgical exercise) effectively prevents postoperative pulmonary complications (PPCs), its cost-effectiveness in valve heart disease (VHD) remains unexplored. This study aims to evaluate the cost-effectiveness of a three-day prehabilitation program for reducing PPCs and improving quality adjusted life years (QALYs) in Chinese VHD patients.

Methods

A cost-effectiveness analysis was conducted alongside a randomized controlled trial featuring concealed allocation, blinded evaluators, and an intention-to-treat analysis. In total, 165 patients scheduled for elective heart valve surgery at West China Hospital were randomized into intervention and control groups. The intervention group participated in a three-day prehabilitation exercise program supervised by a physiotherapist while the control group received only standard preoperative education. Postoperative hospital costs were audited through the Hospital Information System, and the EuroQol five-dimensional questionnaire was used to provide a 12-month estimation of QALY. Cost and effect differences were calculated through the bootstrapping method, with results presented in cost-effectiveness planes, alongside the associated cost-effectiveness acceptability curve (CEAC). All costs were denominated in Chinese Yuan (CNY) at an average exchange rate of 6.73 CNY per US dollar in 2022.

Results

There were no statistically significant differences in postoperative hospital costs (8484 versus 9615 CNY, 95% CI -2403 to 140) or in the estimated QALYs (0.909 versus 0.898, 95% CI -0.013 to 0.034) between the intervention and control groups. However, costs for antibiotics (339 versus 667 CNY, 95% CI -605 to -51), nursing (1021 versus 1200 CNY, 95% CI -330 to -28), and electrocardiograph monitoring (685 versus 929 CNY, 95% CI -421 to -67) were significantly lower in the intervention group than in the control group. The CEAC indicated that the prehabilitation program has a 92.6% and 93% probability of being cost-effective in preventing PPCs and improving QALYs without incurring additional costs.

Conclusions

While the three-day prehabilitation program did not significantly improve health-related quality of life, it led to a reduction in postoperative hospital resource utilization. Furthermore, it showed a high probability of being cost-effective in both preventing PPCs and improving QALYs in Chinese patients undergoing valve surgery.

A qualitative study of the experiences and perceptions of older patients and relatives prior to cardiac surgery

BACKGROUND

Shared decision-making plays an important role in ensuring value-based healthcare in cardiac surgery. However, the personal situations of patients in cardiac care have not been widely explored, and thus, little is known about the decision-making experiences of patients and their relatives before surgery.

OBJECTIVE

To explore the perceptions of patients indicated for cardiac surgery and their relatives during the decision-making process, as well as their experiences of a conversation aimed at achieving shared decision-making in the treatment trajectory.

METHODS

The data were collected through semi-structured in-depth interviews with patients aged ≥70 years who were indicated for cardiac surgery and their relatives until theme saturation. Both inductive and deductive analysis were conducted based on the principles of reflexive thematic analysis.

RESULTS

Interviews with 16 patients and 10 relatives provided in-depth insights into the experiences of patients and their relatives in terms of a shared decision-making process prior to surgery. Overall, 15 subthemes were identified, and these were divided into three themes. In general, the patients' experiences and perceptions were influenced by their (1) general daily functioning. The relatives were more concerned about (2) social expectations and (3) existential uncertainty.

CONCLUSIONS

Patients eligible for cardiac surgery and their families have unique experiences and perceptions during the process of shared decision-making. The subthemes emerging from this study, such as the overestimation of potential medical outcomes by patients and their relatives, who experience fear about the current health situation of their loved one, require careful attention from healthcare professionals during decision-making conversations.

Predictors of health-related quality of life after coronary artery bypass graft surgery

Health-related quality of life (HRQOL) is a multifactorial concept in assessing physical and mental health. This study was performed to evaluate the HRQOL of patients undergoing coronary artery bypass graft (CABG) surgery and the predictors of HRQOL in patients until 1 year after surgery. This cross-sectional study included 110 consecutive patients who underwent elective CABG in a medical center in South Korea. The Short-Form Health Survey, cardiac symptom survey, cardiac self-efficacy, and the Interpersonal Support Evaluation List-12 were used to measure the HRQOL, symptom experience, self-efficacy, and social support, respectively. The regression model explained 42% of the variance in the participants' physical HRQOL. The predictors of the physical HRQOL include the presence of a spouse, post-CABG duration, symptom experience, and self-efficacy. The regression model explained 36% of the variance in the participants' mental HRQOL. The predictors of the mental HRQOL included perceived health status, self-efficacy, and social support. The predictive factors for HRQOL after CABG were the presence of a spouse, post-CABG duration, symptom experience, self-efficacy, and social support. Furthermore, a suitable program and nursing interventions could be implemented to improve the HRQOL of post-CABG patients.

Quality measurement for cardiovascular diseases and cancer in hospital value-based healthcare: a systematic review of the literature

BACKGROUND

This systematic literature review identifies hospital value-based healthcare quality measures, measurement practices, and tools, as well as potential strategies for improving cardiovascular diseases and cancer care.

METHODS

A systematic search was carried out in the PubMed, Embase, CINAHL, and MEDLINE (OvidSP) databases. We included studies on quality measures in hospital value-based healthcare for cardiovascular diseases and cancer. Two reviewers independently screened titles and abstracts, conducted a full-text review of potentially relevant articles, assessed the quality of included studies, and extracted data thematically. This review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, and four validated tools were used for methodological quality assessment.

RESULTS

The search yielded 2860 publications. After screening the titles and abstracts, 60 articles were retrieved for full-text review. A total of 37 studies met our inclusion criteria. We found that standardized outcome sets with patient involvement were developed for some cardiovascular diseases and cancer. Despite the heterogeneity in outcome measures, there was consensus to include clinical outcomes on survival rate and disease control, disutility of care, and patient-reported outcome measures such as long-term quality of life.

CONCLUSION

Hospitals that developed value-based healthcare or are planning to do so can choose whether they prefer to implement the standardized outcomes step-by-step, collect additional measures, or develop their own set of measures. However, they need to ensure that their performance can be consistently compared to that of their peers and that they measure what prioritizes and maximizes value for their patients.

Application of patient decision aids in treatment selection of cardiac surgery patients: a scoping review

BACKGROUND

The choice of treatment is an unavoidable challenge faced in the day to day medical decision making pertaining to patients with organic heart disease. As a professional discipline, cardiac surgery focuses on creating and using the most advanced evidence-based patient decision aids (PtDAs) to achieve high-quality decision-making.

OBJECTIVES

To describe the basic situation, influencing factors, and the outcome of indicators of PtDAs among cardiac surgery patients.

METHODS

Seven electronic databases were systematically searched for relevant reviews on the application of PtDAs among cardiac surgery patients. The methodological framework proposed by Arskey and O'Malley was used to guide the scoping review. The extracted data was analyzed qualitatively and quantitatively.

RESULTS

After dual, blinded screening of titles and abstracts, 12 articles were included in the review. 10 were quantitative studies, 1 was a mixed study, 1 was a qualitative study.

CONCLUSIONS

Compared with the burden of heart disease and the huge evidence base, the application of PtDAs in cardiac surgery is obviously insufficient. The published literature mainly provide information about the factors to be solved from the perspective of researchers, and also summarize obstacle factors. This is the basis for the application and construction of PtDAs in cardiac surgery patients.
