Background: Coronary artery bypass graft surgery is one of the most common cardiac procedures performed worldwide. The longer these patients remain in bed, the greater their risk of postoperative complications and prolonged length of stay.
Local problem: At the authors' institution, the average length of stay after coronary artery bypass graft surgery was 7.27 days, longer than the national average of 6.9 days. This quality improvement project was undertaken to increase these patients' postoperative mobility and thereby reduce their length of stay.
Methods: Data on mobility and length of stay of patients with isolated coronary artery bypass graft surgery during an 8-week period were collected retrospectively to establish preintervention values. These values were compared with postintervention values for an equivalent period. An evidence-based nurse-driven early mobility protocol was used to mobilize appropriate patients from bed to chair on postoperative day 0. This level of mobility was documented as a score of 4 on the Johns Hopkins Highest Level of Mobility Scale.
Results: From before to after protocol implementation, the postoperative length of stay decreased by 1.04 days. None of the 103 patients in the preintervention group scored a 4 on the Johns Hopkins Highest Level of Mobility Scale, compared with 36 of 134 patients in the intervention group. The difference in postoperative length of stay was clinically but not statistically significant (2-sided P = 1.95).
Conclusion: Early mobility may help improve patient outcomes by reducing hospital length of stay and minimizing complications associated with prolonged immobility.
