The concept of a predetermined first patient on the following days trauma list (the golden patient) was introduced to our hospital in April 2009. The golden patient (GP) should already have been seen by an anaesthetist and be ready to be sent for by theatres early. The aim was to improve theatre start times following disappointing results from a previous in-hospital study. It has been shown by others to improve operation start times and could be used to improve trauma services and meet clinical targets more readily. This prospective study involved the collection of planned trauma lists with the designated GP over November and December 2009. Data was collected from theatre logbooks and included patient demographics, theatre arrival, anaesthetic and operation start times. This was compared with the pre-GP data (January and February 2009). A two sample T-test was used to evaluate statistical significance between groups.Introduction

The concept of the golden patient (GP) was introduced to our busy teaching district general hospital, in April 2009, to improve trauma theatre start times following disappointing results from a previous in-hospital study. The GP is a pre-selected first patient on the following day trauma list who is medically fit with a clear surgical plan. The GP should have already been seen by an anaesthetist and be ready to be sent for by theatres early. It has been shown by others to improve operation start times and could be used to improve trauma services and meet clinical targets more readily. This prospective study involved the collection of planned trauma lists with the designated GP over November and December 2009. Data was collected from the theatre logbooks, including patient demographics, theatre reception, anaesthetic and operation start times. This was compared with the pre-GP data (January and February 2009). Graphs showing the comparative mean start times between pre-GP and GP trauma lists, including the 95% confidence interval for the population mean were created. A two sample T test was used to evaluate significance between groups.Introduction
Methods
Templating of preoperative radiographs is routinely recommended prior to knee arthroplasty. We performed this study to assess the reproducibility and accuracy of the templates for three commonly used knee implants (PFC, Kinemax, Scorpio). Six lower limb surgeons templated 10 patients for each of the three designs. The inter and intra-observer reliability and accuracy was calculated. There was marked variation in the reliability of the templating with the tibial insert scoring better than the femoral and the Kinemax being the most reproducible of the three. In general, the intra-observer scores (κ= 0.57–0.81) were better than the inter-observer ones (κ= 0.21–0.60). The Scorpio was the most accurately templated of the three implants, with the percentage correlating with what was actually implanted ranging from 55–62% for the femur and 72–75% for the tibia, with no templated sizes more than 1 size different from the actual implant. The other implants ranged from 38–42% for the femur and 53–58% for the tibia with both having up to 3% more than 1 size difference from the actual implant. We believe that the use of templating in total knee arthroplasty should be interpreted with caution and we urge the development of more accurate prosthesis sizing techniques.
