Remote monitoring following adult cardiac surgery: A paradigm shift?

Background: The Perfect Care (PC) initiative engages, educates, and enrolls adult cardiac surgery patients into a transformational program that includes an app for appointment scheduling, tracking biometric data and patient-reported outcomes, audiovisual visits, and messaging, paired with a digital health kit (consisting of a fitness tracker, scale, and sphygmomanometer). PC aims to reduce postoperative length of stay (LOS) as well as 30-day readmission and mortality. Methods: This was a retrospective review of patients who underwent coronary artery bypass (CAB), valve, or combined CAB and valve procedures at either of the 2 participating hospitals between April 2018 and March 2022. Patients who participated in the PC quality improvement initiative were compared to propensity-matched controls (1:1 matching). The evaluation focused on postoperative LOS and a novel composite measure comprising 30-day readmission and mortality. Results: Remote monitoring (PC) was associated with a shorter postoperative LOS, lower combined rate of 30-day readmission and mortality, and less variation compared to matched non-PC controls. Conclusions: Integrated improvements in postoperative remote monitoring of adult cardiac surgery patients may reduce time in the hospital and post-acute care facilities. Future prioritized efforts include the development of additional, personalized biometric monitoring devices, use of biometric data to augment risk assessment, and investigation of the value of remote monitoring on various patient risk profiles to address potential disparities in care.

Technologic Transformation of Perioperative Cardiac Care and Outcomes.

BACKGROUND: The "Perfect Care" initiative engages, educates, and enrolls adult cardiac surgery patients into a comprehensive program that incorporates remote perioperative monitoring (RPM). This study investigated the impact of RPM on postoperative length of stay, 30-day readmission and mortality, and other outcomes. METHODS: This quality improvement project compared outcomes in 354 consecutive patients who underwent isolated coronary artery bypass and who were enrolled in RPM between July 2019 and March 2022 at 2 centers against outcomes in propensity-matched control patients from a pool of 1301 patients who underwent isolated coronary artery bypass from April 2018 to March 2022 without RPM. Data were extracted from The Society of Thoracic Surgeons Adult Cardiac Surgery Database, and outcomes were analyzed according to its definitions. RPM used perioperative standard practice routines, a digital health kit for remote monitoring, a smartphone application and platform, and nurse navigators. Propensity scores were generated with RPM as the outcome measure, and a 2:1 match was generated using a nearest-neighbor matching algorithm. RESULTS: Patients who underwent isolated coronary artery bypass and who were participating in RPM showed a statistically significant, 15.4% (1 day) reduction in postoperative length of stay (P < .0001) and a 44% reduction in 30-day readmission and mortality (P < .039) compared with matched control patients. Significantly more RPM participants were discharged directly home instead of to a facility (99.4% vs 92.0%; P < .0001). CONCLUSIONS: The RPM platform and associated efforts to engage and monitor adult cardiac surgery patients remotely is feasible, is embraced by patients and clinicians, and transforms perioperative cardiac care by significantly improving outcomes and reducing variation.

Pectus carinatum.

Pectus carinatum or keel chest is a spectrum of progressive inborn anomalies of the anterior chest wall, named after the keel (carina) of ancient Roman ships. It defines a wide spectrum of inborn protrusion anomalies of the sternum and/or the adjacent costal cartilages. Pectus carinatum is often associated with various conditions, notably Marfan disease, homocystinuria, prune belly, Morquio syndrome, osteogenesis imperfecta, Noonan syndrome, and mitral valve prolapse. Treatment of pectus carinatum by nonsurgical methods such as exercise and casting has not been worthwhile, whereas surgical management is simple and successful.

Surgical repair of pectus excavatum and carinatum.

The author discusses different forms of pectus deformities and presents appropriate surgical methods he developed for their correction. For pectus excavatum, the surgical technique includes conservative sub-perichondral resection of deformed costal cartilages and detachment of the xiphoid process. A transverse sternotomy is performed at the upper level of the deformed sternum, which is then bent forward. The corrected sternal position is secured by a "hammock" of synthetic mesh, spread behind the sternum, and attached to the respective cartilage remnants. The pectoralis muscles are then united presternally. The initial steps of pectus carinatum correction are similar to that of pectus excavatum. The sternum, however, is not freed of its environment. A length of 3-4 cm is resected from the distal sternum and the xiphoid process is reattached in the proper anatomical direction. Measures to correct different anatomical varieties, such as pouter pigeon breast, asymmetrical pectus excavatum, and carinatum, are discussed individually.

Quality improvement program decreases mortality after cardiac surgery.

OBJECTIVE: This study investigated the effects of a quality improvement program and goal-oriented, multidisciplinary protocols on mortality after cardiac surgery. METHODS: Patients were divided into two groups: those undergoing surgery (coronary artery bypass grafting, isolated valve surgery, or coronary artery bypass grafting and valve surgery) after establishment of the multidisciplinary quality improvement program (January 2005-December 2006, n = 922) and those undergoing surgery before institution of the program (January 2002-December 2003, n = 1289). Logistic regression and propensity score analysis were used to adjust for imbalances in patients' preoperative characteristics. RESULTS: Operative mortality was lower in the quality improvement group (2.6% vs 5.0%, P < .01). Unadjusted odds ratio was 0.5 (95% confidence interval 0.3-0.8, P < .01); propensity score-adjusted odds ratio was 0.6 (95% confidence interval 0.4-0.99, P = .04). In multivariable analysis, diabetes (P < .01), chronic renal insufficiency (P = .05), previous cardiovascular operation (P = .04), congestive heart failure (P < .01), unstable angina (P < .01), age older than 75 years (P < .01), prolonged pump time (P < .01), and prolonged operation (P = .05) emerged as independent predictors of higher mortality after cardiac surgery, whereas quality improvement program (P < .01) and male sex (P = .03) were associated with lower mortality. Mortality decline was less pronounced in patients with than without diabetes (P = .04). CONCLUSION: Application of goal-directed, multidisciplinary protocols and a quality improvement program were associated with lower mortality after cardiac surgery. This decline was less prominent in patients with diabetes, and focused quality improvement protocols may be required for this subset of patients.
