Greater functional improvement in patients with diabetes after rehabilitation following cardiac surgery.

BACKGROUND: Diabetes increases the risk of in-hospital complications in medical or surgical patients. Few data are available in the rehabilitation phase after cardiac surgery. AIM: To assess the influence of diabetes on outcome and complication rate in the rehabilitation phase after cardiac surgery. METHODS: Data prospectively recorded in the Hospital Information System from 5261 patients consecutively admitted between 1 January 2008 and 31 May 2013 for a comprehensive cardiac rehabilitation programme directly after cardiac surgery were analysed retrospectively. RESULTS: The study cohort included 1285 (24%) patients with diabetes and 3976 (76%) without. Coronary artery bypass graft (CABG) was more frequent in patients with diabetes (58% vs. 37%, P < 0.01), and valvular surgery was more frequent in patients without diabetes (37% vs. 22%, P < 0.01). Patients with diabetes were more disabled after surgery, with severe disability (Barthel Index < 60) observed in 22% (vs. 17% in patients without diabetes, P < 0.001). During rehabilitation, complications were more frequent in patients with diabetes than those without (28% vs. 21%, P < 0.01); in particular, patients with diabetes had more infections, heart failure and more difficult surgical wound healing. However, the improvement in the Barthel Index was greater in patients with diabetes (+16 ± 15) than without (+13 ± 15, P < 0.001). CONCLUSIONS: In a large cohort of patients directly admitted to an early inpatient rehabilitation programme after cardiac surgery, those with diabetes were more disabled. Nonetheless, and despite the higher rate of complications, patients with diabetes had the greatest benefit in terms of functional improvement.

A prospective examination of disease management program use by complex cardiac outpatients.

BACKGROUND: The use of disease management programs (DMPs) by patients with cardiovascular disease (CVD) is associated with improved outcomes. Although rates of cardiac rehabilitation (CR) use are well established, less is known about other DMPs. The objectives of this study were to describe the degree of DMP utilization by CVD outpatients, and examine factors related to use. METHODS: This study represents a secondary analysis of a larger prospective cohort study. In hospital, 2635 CVD inpatients from 11 hospitals in Ontario Canada completed a survey that assessed factors affecting DMP utilization. One year later, 1803 participants completed a mailed survey that assessed DMP utilization. RESULTS: One thousand seventy-three (59.5%) participants reported using at least 1 DMP. Overall, 951 (52.7%) reported participating in cardiac rehabilitation, and among participants with a comorbid indication, 212 (41.2%) reported attending a diabetes education centre, 28 (25.9%) attended stroke rehabilitation, 35 (12.9%) used a heart failure clinic, and 13 (11.7%) attended a smoking cessation program. A multinomial logistic regression analysis showed that compared with no DMP use, participants that attended 1 or multiple programs were younger, married, diagnosed with a myocardial infarction, less likely to have had a percutaneous coronary intervention and had higher perceptions of personal control over their heart condition. There were few differences between participants that used 1 vs multiple DMPs, however, having diabetes or comorbid stroke significantly increased the likelihood of multiple DMP use. CONCLUSIONS: Approximately 40% of CVD outpatients do not access DMPs. An integrated approach to vascular disease management appears warranted.

Cardiac rehabilitation after cardiac surgery is limited by gender and length of hospitalisation.

BACKGROUND: Cardiac rehabilitation (CR) is recommended after cardiac surgery. Secondary prevention through exercise training is one of the best scientifically-proven ways of decreasing mortality and enhancing quality of life in cardiovascular disorders. Studies into the use of CR in different groups of patients after cardiac surgery are limited. AIM: To find the factors determining the reasons for the lack of CR in cardiac surgery patients. METHODS: The study group consisted of 82 patients (mean age 58.6 years, 80.7% male) in stable II/III NYHA class, who had undergone coronary artery bypass graft surgery, valvular surgery, or both. The following were analysed: age, gender, body mass index, basic laboratory results such as serum lipids level, cholesterol ratio LDL/HDL, creatinine and glucose levels, results of electrocardiography, echocardiography and coronary arteriography, presence of hypertension, diabetes, coronary artery disease, renal failure, previous stroke, obliteration of peripheral arteries, EuroSCORE and length of hospitalisation. Patients were divided into two groups: those referred for CR (n = 46, the CR group) and those referred for CR but who did not receive it (n = 36, non-CR group). RESULTS: From multiple logistic regression analysis with backward stepwise, only female gender (p = 0.0208, OR = 0.07) and length of hospitalisation (p = 0.0198, OR = 1.17) were significant for non-CR patients. CONCLUSIONS: We found a lower rate of use of CR after cardiac surgery in those patients hospitalised for longer periods, and in women.
