ABSTRACT
Elective patients undergoing anaesthetic pre-operative assessment are usually allocated the same period of time with a nurse practitioner, leading to potential inefficiencies in patient flow through the clinic. We prospectively collected data on 8519 patients attending a pre-operative assessment clinic. The data set were split into derivation and validation cohorts. Standard multiple regressions were used to construct a model in the derivation cohort, which was then tested in the validation cohort. Due to missing data, 2457 patients were not studied, leaving 5892 for analysis (3870 in the derivation cohort and 2022 in the validation cohort). The mean (SD) pre-operative assessment time was 46 (12) min. Age, ASA physical status, nurse practitioner and surgical specialty all influenced the time spent in pre-operative assessment. The predictive equations calculated using the derivation cohort, based on age and ASA physical status, correctly estimated duration of consultation to within 20% of the maximum predicted time in 74.2% of the validation cohort. We conclude that if age and ASA physical status are known before the pre-operative assessment consultation, it could allow appointment times to be allocated more accurately.

UNLABELLED: Health Related Quality of Life questionnaires are frequently used for research, however only recently has their use been recommended in the routine clinical management of pituitary patients. Questionnaires frequently have complex scoring systems, and may be cumbersome, limiting widespread application. Touch-screen technology can overcome these limitations. We have developed a touch-screen 'Questions on Life Satisfaction-Hypopituitarism' QLS-H (Flash 5 Action script, program design by IG) questionnaire and compared its use and accuracy with a paper version questionnaire in 50 pituitary patients who were attending routine clinics. The HRQoL Z-score for the patient group was lower than the average for the normal UK population, as might be predicted for this patient group. There was no statistically significant difference between scores obtained by the touch-screen and paper questionnaires; mean (SD) Z score was -1.33 (1.4) for touch-screen and -1.26 (1.5) for paper. The touch-screen was preferred by 80% of patients, and quicker to complete (<5min). Additionally, there were significant errors in 14 (28%) of manually scored paper questionnaires. IN CONCLUSION: Touch-screen QLS-H questionnaires have advantages over the paper version for the routine clinical assessment of patients with hypopituitarism.
