Preoperative assessment should occur as early as possible in the patient’s care pathway. Greater than two weeks preoperatively is recommended as good practice and preferably as close to the point of contemplation of surgery as possible to allow for the optimisation of chronic health conditions and health behaviours, so that all essential resources and obstacles can be anticipated prior to...

Where possible, it is preferable for one stop arrangements to be implemented so that patients can attend preoperative assessment during the same hospital visit as their surgical outpatient assessment. Ideally, the frequency of high risk clinics should allow for one stop patient visits when appropriate. The volume of information may mean that the wrong details are prioritised or recollected.

Each hospital should have agreed written preoperative policies or guidelines, following national guidelines where available, including but not limited to:

• preoperative tests and investigations^69,70
• preoperative ordering for potential blood transfusion
• preoperative fasting schedules and the administration of preoperative carbohydrate drinks^{41,42,71, 73}
• default to day surgery for suitable procedures
• escalation to higher...

Each hospital should have agreed protocols, following national guidance where available, including, but not limited to:

• management of anaemia including parenteral iron therapy to reduce the risk of allogenic blood transfusion^{75,76,77,78,79}
• antacid prophylaxis
• preoperative nutritional screening.

The secondary care preoperative service should liaise closely with primary care, other secondary care professionals and commissioners to promote a ‘fitness for referral’ process in line with best practice.

Agreed internal referral pathways to other specialties should be in place for the minority of cases in which this may be required to expedite further investigation and patient optimisation. This should be done in close collaboration between the preoperative assessment lead and nominated representatives from appropriate specialties (e.g. cardiology, diabetes, renal, respiratory and geriatric medicine).

Where the risk of an adverse patient outcome associated with surgery are identified as being high, the preoperative assessment consultation should facilitate a shared patient discussion, which may result in a well-informed individual opting for non-surgical management. Under such circumstances the decision making process should be endorsed through close collaborative discussion with surgical colleagues – this is ideally conducted and...

The output from consultations with patients at increased risk of mortality or morbidity must be documented in the patient’s medical notes. In addition, mechanisms for clear communication of these consultations to patients, anaesthetists, surgeons, general practitioners and other healthcare workers should be in place.^6,54

Consideration should be given to the use of formal prehabilitation pathways as well as services for nutritional assessment, smoking cessation, alcohol / drug addiction services and psychological support.^_81,82,83

Documentation and communication of information on preoperative preparation are essential. Electronic systems should be considered to enable the capture and sharing of information, support risk identification and allow data to be collected and available for audit and research purposes.^48,80,84
