Guidelines-based diagnostic process does increase hospital delay in a cohort of colorectal cancer patients: a population-based study

This is an investigation of factors determining hospital delay until treatment in an unrestricted population of colorectal cancer patients in the western part of the Netherlands. All patients with newly diagnosed colon (n = 2146) and rectal carcinoma (n = 1036) in the period 2006-2008 were included in analyses of inhospital delay (first hospital visit until first treatment >35 days). One-third of all patients were also available for analyses of prehospital delay (enrolment until first hospital visit >7 days). Patient, tumour and process factors predicting delay were examined in logistic regression models. The median prehospital and inhospital time intervals were 2 days [(p25-p75) 0-16] and 32 days (17-49), respectively, for colon cancer patients and 7 days (1-21) and 43 days (33-60) for rectal cancer patients. After adjustment for patient and tumour factors, colon and rectal cancer patients with first hospital visit before histological confirmation of cancer, complete diagnostic assessment or discussed in a multidisciplinary meeting had a higher probability of increased inhospital delay. Furthermore, first hospital visit before histological confirmation of cancer was associated with decreased prehospital delay in colon and rectal cancer patients. A guidelines-based diagnostic process (considered high quality of care) and multidisciplinary collaboration were associated with increased hospital delay in colorectal cancer patients. c 2014 Wolters Kluwer Health | Lippincott Williams & Wilkins.
