Background: Many studies have shown that rectal bleeding is a good indicator of underlying colorectal pathology, and that ost of the lesions in patients presenting with rectal bleeding lie in the left side of the colon [1, 5, 9, 12, 23, 26]. The recent acceptance of the nurse-practitioner by the National Health Service may allow the use of nurse-endoscopists to develop throughout the United Kingdom. This study aimed to audit a unique nurse-led direct-access nurse-endoscopy service with regard to its efficacy and cost effectiveness, and to monitor patient satisfaction and direct referrals from the primary health sector.
Methods: A nurse-led open-access flexible sigmoidoscopy (OAFS) service for patients reporting fresh rectal bleeding was established at our center in February 1996. A prospective audit of sigmoidoscopic findings and a retrospective analysis of referral patterns from local general practitioners were conducted. A questionnaire survey of both patient and general practitioner satisfaction also was conducted at the same time.
Results: Since February 1996, 706 patients have been referred to our service. Rectal bleeding was by far the most common cause for referral, representing the dominant symptom in 92% of the referrals received. Although 99% of the patients underwent a complete sigmoidoscopic examination, 16% of these examinations were limited because of several factors combined. A cause for bleeding was identified in 91% of the patients, with 24% of them experiencing subsequent significant pathology. Of the patients surveyed, 99% were satisfied with the service provided. The results also show nurse-led OAFS to be a more effective use of financial resources, costing $90 less per patient than general practitioner referrals sent to a consultant for further action.
Conclusions: Rectal bleeding is a good indicator of underlying colorectal disease. Most of the significant lesions presenting with this symptom are found in the left side of the colon. A nurse-led OAFS is safe, effective, and acceptable to patients. It also is more cost effective than a consultant-led service.
