We will also carry out an editorial review of all recommendations , for example to ensure that they comply with NICE’s duties under equalities legislation.  \nThis update is being undertaken as part of the guideline review cycle.  \nThe update was commissioned to include the results of the 2012 Heath Technology Assessment (HTA 2012) ‘What is the value of routinely testing full blood count, urea and electrolytes, and pulmonary function tests before elective surgery in patients with no apparent clinical indication and in subgroups of patients with common comorbidities: a systematic review of the clinical and cost-effective literature’. In the areas where new evidence was identified as part of the NICE review update, full searches will be undertaken. No additional searches will be undertaken for areas where the NICE review update found no new evidence. Formal consensus methods will be used, in addition to the updated evidence reviews, to support the development of recommendations, including those where no evidence review is to be conducted.  \n3 Need for the guideline  \n3.1 Incidence  \na) Many apparently healthy people are tested preoperatively to check for undetected conditions that might affect their treatment. In 2012/2013 the NHS in England completed 10.6 million operations , compared to 6.61 million in 2002/2003. This is an increase of 60% .  \n3.2 Current practice  \na) In 2003 NICE issued guidance for the use of routine preoperative tests for healthy children and adults , and adults with mild, moderate and severe comorbidities (cardiovascular, respiratory, renal disease and obesity), undergoing elective surgery (NICE clinical guideline 3) .  \nb) A generic preoperative test is defined as an investigation done before an operation that is recommended for all patients of a particular type (for example, people in a certain age range or with a particular comorbidity) that is not directly linked to either the surgical procedure or the condition for which the operation is for.  \nc) The American Society of Anesthesiologists (ASA) Physical Status Classification System is often used by UK anaesthetists to establish a person’s functional capacity. ASA grades are a simple scale describing a person’s fitness to be given an anaesthetic for a procedure. However, the ASA clearly states that it does not endorse any elaboration of these definitions within the classification system.  \nTable 1. American Society of Anesthesiologists Physical Status Classification System  \n\n| ASA grade 1 | A normal healthy patient, (that is, without any clinically important comorbidity and without a clinically significant past/present medical history) |\n| --- | --- |\n| ASA grade 2 | A patient with mild systemic disease |\n| ASA grade 3 | A patient with severe systemic disease |\n| ASA grade 4 | A patient with severe systemic disease that is a constant threat to life |\n| ASA grade 5 | A moribund patient who is not expected to survive without the operation |\n| ASA grade 6 | A declared brain-dead patient whose organs are being removed for donor purposes |\n\nd) Clinical opinion currently varies on how useful it is to test apparently healthy people before their operations. There is also increasing awareness that such tests can alarm people unnecessarily for little clinical benefit. Evidence shows that clinicians do not often change how they manage people’s care, even if tests in relatively healthy people give abnormal results. Therefore, if preoperative tests are only ordered when healthy people undergoing surgery have a specific condition or there is a reasonable suspicion they have that condition , the potential sa","cbCaiuk2ZOkdPO57","https://ap.wps.com/l/cbCaiuk2ZOkdPO57","pdf",210866,13,"English","# Preoperative tests: the use of routine preoperative tests for elective surgery (update)\n## The remit\n## Need for the guideline\n### Incidence\n### Current practice\n## The guideline\n### Population\n### Groups that will be covered","[{\"question\":\"What does this NICE scope update cover?\",\"answer\":\"It updates the NICE clinical guideline on routine preoperative tests for elective surgery, defining what the guideline will examine and what it will not, and which sections will be updated.\"},{\"question\":\"How are generic preoperative tests defined?\",\"answer\":\"A generic preoperative test is an investigation recommended for all patients of a particular type, such as an age range or comorbidity, and not directly linked to the specific surgery or the condition the operation treats.\"},{\"question\":\"What recommendation approach is used in the updated guideline?\",\"answer\":\"The guideline continues using the existing traffic-light system to show whether a test is recommended, may be considered, or is not recommended, supported by updated evidence reviews and formal consensus methods.\"}]","Preoperative tests - update - Scope | PDF",1790285014,33]
