ABSTRACT
Early mobility and activity programmes following cardiac surgery are vital for improved patient outcomes, as they accelerate the recovery of functional capacity and walking distance. We observed that only 5.3% of our patients achieved a Functional Independence Measurement (FIM) score of 80% or more by the third postoperative day (POD). Additionally, the average 6-minute walk distance achieved by the fourth POD was only 188 m. Therefore, a quality improvement (QI) project was implemented with the aim of attaining a FIM score of 80% by the third POD for more than 80% of patient underwent/undergoing cardiac surgery without complications.A model-for-improvement framework was used to drive continuous improvement. This project was implemented in February 2021. Baseline data were prospectively collected between November 2020 and January 2021 (preintervention). Outcomes were analysed using standard control chart rules to detect changes over time. Unpaired Student t-tests assessed significant differences in mean levels between two groups, (preintervention vs postintervention).χ2 tests were conducted between the two groups according to gender and patient satisfaction scores.The percentage of patients who achieved a FIM score of 80% or more by the third POD gradually increased to 91.4% 5 months following programme implementation and was sustained thereafter. The mean patient FIM score significantly improved to 81.20±3.77 (p<0.001) by the third POD. Similarly, the mean 6-minute walk distance increased to 267.90±36.10 m (p<0.001) by the fourth POD. The percentage of patients who displayed the level of confidence needed to carry out activities of daily living (ADL) and exercises independently at home increased to 89.4% (p<0.001) by the fifth POD. No adverse events associated with the mobility and activity programme were reported.This QI project demonstrated a substantial improvement in patient functional independence, walking distance and the level of confidence needed to independently carry out ADL and exercises following cardiac surgery.

Early mobilisation following cardiac surgery is vital for improved patient outcomes, as it has a positive effect on a patient's physical and psychological recovery following surgery. We observed that patients admitted to the cardiothoracic intensive care unit (CTICU) following cardiac surgery had only bed exercises and were confined to bed until the chest tubes were removed, which may have delayed patients achieving functional independence. Therefore, the CTICU team implemented a quality improvement (QI) project aimed at the early mobilisation of patients after cardiac surgery.A retrospective analysis was undertaken to define the current mobilisation practices in the CTICU. The multidisciplinary team identified various practice gaps and tested several changes that led to the implementation of a successful early mobility programme. The tests were carried out and reported using rapid cycle changes. A model for improvement methodology was used to run the project. The outcomes of the project were analysed using standard 'run chart rules' to detect changes in outcomes over time and Welch's t-test to assess the significance of these outcomes.This project was implemented in 2015. Patient compliance with early activity and mobilisation gradually reached 95% in 2016 and was sustained over the next 3 years. After the programme was implemented, the mean hours required for initiating out-of-bed-mobilisation was reduced from 22.77 hours to 11.74 hours. Similarly, functional independence measures and intensive care unit mobility scores also showed a statistically significant (p<0.005) improvement in patient transfers out of the CTICU.Implementing an early mobility programme for post-cardiac surgery patients is both safe and feasible. This QI project allowed for early activity and mobilisation, a substantial reduction in the number of hours required for initiating out-of-bed mobilisation following cardiac surgery, and facilitated the achievement of early ambulation and functional milestones in our patients.
