This paper describes an audit loop. We studied patients undergoing hip and knee surgery (arthroplasty and revision arthroplasty). All the patients were ‘complex elective’. I.e. they were either ASA grade 3 or 4, or had a body mass index in excess of 40. We collected data concerning postoperative admissions to HDU, ICU and PACU (planned and unplanned rates of admission, length of stay). We also noted mortality.

In the first part of the study (April 2005 to March 2006) we studied 298 patients. All patients were assessed independently by an anaesthetist on the day of surgery.

A multidisciplinary preoperative assessment clinic commenced in April 2006. After this date all patients were assessed preoperatively by a multidisciplinary anaesthetic lead team (anaesthetist, orthopaedic senior house officer, nurse practitioner). The need for an HDU or ICU bed was assessed and the bed was booked at part of the pre-operative plan.

In the second part of the study (May 2006 to April 2009) a further 1147 arthroplasty patients were studied. Data was again collected regarding HDU, ICU, PACU and mortality as noted above.

We found statistically significant (p=0.001) reductions in the admissions to PACU (22% down to 10%) and in mortality (6.1% down to 1.2%) after the introduction of the pre assessment clinic. There was also statistically significant (p=0.01) reduction in the HDU length of stay(2.1 days to 1.6 days), ITU unplanned admissions (1.3% to 0.4%) and the ITU length of stay in days (2.3 to 1.9 days).

We also estimated cost savings of nearly £50 000 in the second limb of the study. This is based on the average decrease in HDU and ICU length of stay.

We recommend the use of a multidisciplinary pre assessment clinic for complex orthopaedic surgery.
