Addressing the Quality of Hospital Care of Colorectal Cancer Patients Undergoing Surgery: What Can We Learn From the National Bowel Cancer Audit?

Introduction The National Bowel Cancer Audit (NBOCA) is the largest database in the United Kingdom that audits real-world data and allows comparison of the quality of care for colorectal cancer patients. This study aimed to highlight relevant clinical factors in the NBOCA that contribute to variation in the quality of care provided in different hospitals. Methods Data from 36,116 patients with colorectal cancer who had undergone surgery were obtained from the NBOCA. These were patients from 145 and 146 hospitals from the years 2016 and 2017, respectively. A validated multiple linear regression was performed to compare the identified clinical factors with various quality outcomes. The quality outcomes defined in this study were the length of hospital stay of more than five days, two-year mortality, 30-day unplanned readmission rate, 90-day mortality, and 18-month stoma rate. Results Four clinical factors (laparoscopy rate, abdominal-perineal-resection-of-rectum, pre-operative radiotherapy, and patients with distant metastases) were shown to have a significant (p < 0.05) impact on the length of hospital stay of more than five days and the 18-month stoma rate. The 18-month stoma rate was also a significant predictor (p < 0.001) with two-year mortality. Conclusion The NBOCA should consider adjusting for these factors when reporting the quality of care provided in hospitals. Hospitals should monitor the four clinical factors for colorectal cancer patients during perioperative care. When formulating a management plan for patients with colorectal cancer, clinicians should consider these factors along with the individual patient's history.
