Trends in colorectal day case surgery in NHS Trusts between 1998 and 2005.
OBJECTIVE
Day case surgery is safe and offers potential benefits to both patients and healthcare providers. This study aimed to describe national changes in colorectal day case workload between 1998 and 2005.


METHODS
Admission data relating to Office of Population Censuses and Surveys Classification of Surgical Operations and Procedures (4th revision) (OPCS-4) coloproctology operation codes were analysed using the Hospital Episode Statistics (HES) database. Day case rates (DCRs) were calculated as the proportion of elective cases performed on an ambulatory basis.


RESULTS
In total, 3 119 058 colorectal admissions were recorded on the HES database between 1998 and 2005; 1 891 474 (61%) of these were for lower gastrointestinal endoscopies. Emergency cases accounted for 527 665 (17%), elective inpatient cases for 406 368 (13%) and elective day cases for 293 551 (9%) admissions. Throughout the study period the DCRs for five commonly performed elective colorectal procedures were: 0.70 for anal lesion excisions (OPCS-4 codes: H48.1, H48.2 and H48.3); 0.16 for haemorrhoidectomy (OPCS-4 code: H51.1); 0.63 for anal fissure procedures (OPCS-4 codes: H56.2 and H56.4); 0.39 for elective procedures for anal fistula (OPCS-4 codes: H55.1, H55.2, H55.3 and H55.4); 0.37 for elective pilonidal surgery (OPCS-4 codes: H59 and H60.2). Two emergency operations, drainage of perianal and pilonidal abscesses (OPCS-4 codes: H58.2 and H60.3 respectively), were identified as operations potentially amenable to day surgery. Over the seven study years, an annual average of 8559 (+/-SD 307) admissions were coded to drainage of a perianal abscess and 4676 (+/-SD 478) admissions to drainage of pilonidal abscess. The average annual bed usage associated with these procedures was 18 831 (+/-SD 718) and 7623 (+/-SD 436) bed days respectively.


CONCLUSIONS
Colorectal day case surgery is currently under-exploited in the NHS. By lifting some of the barriers to day case surgery significant resource savings may be possible.
