The effect of early follow-up after open cardiac surgery in a student clinic.

Objectives. Readmission rates following open cardiac surgery are high, affecting patients and the cost of care. This study aimed to investigate the effect of early additional follow-up after open cardiac surgery when 5th-year medical students conducted follow-ups under the supervision of physicians. The primary endpoint was unplanned cardiac-related readmissions within one year. The secondary outcomes were the detection of impending complications and health-related quality of life (HRQOL). Methods. Patients undergoing open cardiac surgery were prospectively included. For intervention, additional follow-up visits, including point-of-care ultrasound, were conducted by supervised 5th-year medical students on postoperative days 3, 14 and 25. Unplanned cardiac-related readmissions, including emergency department visits, were registered within the first year of surgery. Danish National Health Survey 2010 questionnaire was used for HRQOL. In standard follow-up, all patients were seen 4-6 weeks postoperative. Results. For data analysis, 100 of 124 patients in the intervention group and 319 of 335 patients in the control group were included. The 1-year unplanned readmission rates did not differ; 32% and 30% in the intervention and control groups, respectively (p = 0.71). After discharge, 1% of patients underwent pericardiocentesis. The additional follow-up initiated scheduled drainage, contrary to more unscheduled/acute drainages in the control group. Pleurocentesis was more common in the intervention group (17% (n = 17) vs 8% (n = 25), p = 0.01) and performed earlier. There was no difference between groups on HRQOL. Conclusion. Supervised student-led follow-up of newly cardiac-operated patients did not alter readmission rates or HRQOL but may detect complications earlier and initiate non-emergent treatment of complications.

Early, dedicated follow-up and treatment of pleural effusions enhance the recovery rate after open cardiac surgery: results from a randomized, clinical trial.

OBJECTIVES: Recent studies conclude that cardiac surgery patients are prone to both mortality and morbidity in the weeks after discharge. Complications such as pleural and pericardial effusions may influence physical recovery due to symptoms such as dyspnoea, chest pain and fatigue. Dedicated follow-up and timely treatment of postoperative complications are suggested. METHODS: A randomized, controlled intervention trial including 76 patients, in the ratio of 1 : 1. Patients scheduled for elective on-pump coronary artery bypass grafting and/or aortic valve replacement were eligible for inclusion. Patients were randomized to either standard postoperative care or complementary follow-up visits with clinical examinations, focused chest sonography and protocol-driven thoracentesis if applicable. Primary outcomes were the mean change in walking distance, peak expiratory flow and EuroQOL from baseline to 30 days after surgery. RESULTS: The mean difference in walking distance after 30 days was 15% (65 ± 22 m) between groups, P = 0.017. No differences were found in the peak expiratory flow or EuroQOL. In patients with pleural effusion, walking distance improved by 22% after thoracentesis (81 ± 42 m), P < 0.0001, and peak expiratory flow improved by 26% (1.1 ± 1.2 l/min), P < 0.001. CONCLUSIONS: Supplemental dedicated follow-up and treatment of postoperative effusions enhance recovery by 15% compared with standard care, measured by improvement in the walking distance 1 month after cardiac surgery.

30-day mortality after coronary artery bypass grafting and valve surgery has greatly improved over the last decade, but the 1-year mortality remains constant.

INTRODUCTION: European system for cardiac operative risk evaluation (EuroSCORE) is a valuable tool in control of the quality of cardiac surgery. However, the validity of the risk score for the individual patient may be questioned. The present study was carried out to investigate whether the continued fall in short-term mortality reflects an actual improvement in late mortality, and subsequently, to investigate EuroSCORE as predictor of 1-year mortality. METHODS: A population-based cohort study of 25,602 patients from a 12-year period from three public university hospitals undergoing coronary artery bypass grafting (CABG) or valve surgery. Analysis was carried out based on EuroSCORE, age and co-morbidity factors (residual EuroSCORE). RESULTS: During the period the average age increased from 65.1 ± 10.0 years to 68.9 ± 10.7 years (P < 0.001, one-way ANOVA), and the number of females increased from 26.0% to 28.2% (P = 0.0012, Chi-square test). The total EuroSCORE increased from 4.67 to 5.68 while the residual EuroSCORE decreased from 2.64 to 1.83. Thirty-day mortality decreased from 4.07% in 1999-2000 to 2.44% in 2011-2012 (P = 0.0056; Chi-square test), while 1-year mortality was unchanged (6.50% in 1999-2000 vs. 6.25% in 2011-2012 [P = 0.8086; Chi-square test]). DISCUSSION: The study demonstrates that both co-morbidity and age has a great impact on 30-day mortality. However, with time the impact of co-morbidity seems less. Thus, age is more important than co-morbidity in late mortality. The various developments in short and long-term mortality are not readily explained. CONCLUSION: Although 30-day mortality of CABG and valve surgery patients has decreased during the 12-year period, the 1-year mortality remains the same.
