The systematicart & science surgical nursing approach ensures that nurses undertake a review of the patients medical history and patient information, a medicines review, and a nursing admitted to hospital. The NHS Modernisation and social assessment. Agency (2002) produced a guide to improving The nursing documentation used is also operating theatre performance. It described how prepared in advance so that it guides the nurse the pre-operative assessment of day case patients through the pre-operative assessment process in and inpatients can influence the use of theatre time. the same way each time.

The assessment process can be divided assessment include (Association of Anaesthetists into four stages: of Great Britain and Ireland 2001): • Stage one: medical history. • Identifying potential anaesthetic difficulties • Stage two: nursing assessment. and existing medical conditions. • Stage three: investigations and clinical scores. • Improving safety by assessing and quantifying risk. • Stage four: information giving. • Enabling post-operative care to be planned. Stage one: medical history On arrival at the clinic • Providing the opportunity for explanation patients are given a health questionnaire that is and discussion, thus allaying fear and anxiety. designed to address each system of the body, including the patients frailty score, height, weight, Bramhall (2002) stated that the principles of body mass index, neck movement and oxygen pre-operative assessment were to identify the saturations on air.
