Abstract
PURPOSE: Substantial gaps exist between clinical practice and evidence-based cancer care, potentially leading to adverse clinical outcomes and decreased quality of life for cancer patients. This study aimed to evaluate the usefulness of clinical pathways as a tool for improving quality of cancer care, using breast, colon, and rectal cancer pathways as demonstrations. METHODS: Newly diagnosed patients with invasive breast, colon, and rectal cancer were enrolled as pre-pathway groups, while patients with the same diagnoses treated according to clinical pathways were recruited for post-pathway groups. RESULTS: Compliance with preoperative core biopsy or fine-needle aspiration, utilization of sentinel lymph node biopsy, and proportion of patients whose tumor hormone receptor status was stated in pathology report were significantly increased after implementation of clinical pathway for breast cancer. For colon cancer, compliance with two care processes was significantly improved: surgical resection with anastomosis and resection of at least 12 lymph nodes. Regarding rectal cancer, there was a significant increase in compliance with preoperative evaluation of depth of tumor invasion, total mesorectal excision treatment of middle- or low-position rectal cancer, and proportion of patients who had undergone rectal cancer surgery whose pathology report included margin status. Moreover, total length of hospital stay was decreased remarkably for all three cancer types, and postoperative complications remained unchanged following implementation of the clinical pathways. CONCLUSIONS: Clinical pathways can improve compliance with standard care by implementing evidence-based quality indicators in daily practice, which could serve as a useful tool for narrowing the gap between clinical practice and evidence-based care.
