Table 1 Guideline synthesis relevant to selective preoperative assessment
Guideline/source
Core recommendation
Relevance to selective assessment
Gap
NICE CG188 gallstone disease[1]Supports definitive management with laparoscopic cholecystectomy and early surgery in acute presentationsStrengthens the argument that avoidable pathway delay mattersDoes not specify anaesthetic clinic criteria
NICE NG45 preoperative tests[2]Recommends selective testing based on surgical grade and comorbiditySupports risk-based rather than universal investigationFocuses on tests rather than full clinic attendance
WSES 2020 acute cholecystitis[3]Supports early laparoscopic cholecystectomy when feasibleAligns with streamlined access to surgeryDoes not define pre-assessment omission criteria
Tokyo Guidelines 2018[4,5]Provides severity grading and surgical management principlesEmphasises patient selection and safe cholecystectomyDoes not address direct-to-surgery assessment pathways
ASA preanaesthesia evaluation[10,11]Evaluation should be appropriate to patient and procedureSupports tailored evaluation and escalationRequires local implementation detail
AUGIS acute gallstone pathway[9]Promotes timely management of acute gallstone diseaseRelevant to United Kingdom Hot Gallbladder Pathway designImplementation varies by resources

Domain
Examples
Rationale
Cardiorespiratory symptomsExertional chest pain, unexplained dyspnoea, syncope, decompensated heart failure, unstable asthma/COPDMay alter anaesthetic plan, investigation and perioperative monitoring
Functional capacity/frailtyPoor exercise tolerance, falls, unintentional weight loss, cognitive impairment, dependence in activities of daily livingASA may underrepresent frailty-related risk
Medication complexityWarfarin/DOACs, antiplatelets, insulin, immunosuppression, high-dose opioidsRequires perioperative planning and possible bridging/adjustment
Airway/anaesthetic historyPrevious difficult airway, malignant hyperthermia risk, severe postoperative nausea/vomiting, previous ICU admissionRequires anaesthetic planning and documentation
Obesity and sleep-disordered breathingSevere obesity, suspected OSA, obesity hypoventilation symptomsMay influence airway, postoperative monitoring and day-case suitability
Abnormal investigationsUnexplained anaemia, renal impairment, electrolyte disturbance, deranged liver function suggesting CBD stonesMay require optimisation, ERCP or altered timing
Social/discharge concernsNo adult escort, poor understanding, language barriers, safeguarding concernsMay affect day-case/discharge safety
Table 3 Objective findings and limitations of the illustrative United Kingdom Hot Gallbladder Pathway service evaluation
Aspect
Objective finding or interpretation
Cohort511 adults undergoing laparoscopic cholecystectomy, January 2020-January 2025
Risk distribution401 ASA I-II (78.5%); 110 ASA III-IV (21.5%)
Assessment pathway334 (65.4%) without formal clinic-based pre-assessment; 177 (34.6%) with formal assessment; all ASA III-IV patients formally assessed
Recorded outcomesNo anaesthetic-related adverse event identified; one cancellation (0.2%), unrelated to anaesthetic factors
InterpretationSupports feasibility in a selected cohort; does not establish equivalence or safety for rare events
Unmeasured outcomesWaiting time, attributable recurrent admission, patient-reported outcomes and cost-effectiveness
Key limitationsRetrospective, single-trust, clinician-selected, potential ASA misclassification and rare-event underpowering
Table 4 Suggested eligibility criteria for direct listing without routine clinic-based pre-assessment
Criterion
Direct listing suitable when
Formal assessment required when
ASA statusASA I-II with stable or absent comorbidityASA III-IV or uncertain classification
Functional capacityGood exercise tolerance and no unexplained symptomsPoor functional capacity, dyspnoea, chest pain, syncope
MedicationSimple medication profile, no complex anticoagulationWarfarin/DOAC complexity, antiplatelet uncertainty, insulin complexity
InvestigationsRecent blood tests reviewed and acceptableUnexplained anaemia, renal impairment, electrolyte abnormality, suspected CBD stones
Anaesthetic historyNo previous difficult airway or major anaesthetic complicationPrevious difficult airway, malignant hyperthermia risk, severe postoperative complication
Frailty/social factorsIndependent, adequate discharge supportFrailty, cognitive impairment, safeguarding or discharge concerns
Table 5 Practical recommendations and evidence of strength
Recommendation
Suggested approach
Strength of rationale
Direct listing for selected low-risk patientsASA I-II, no red flags, recent investigations reviewed, same-day anaesthetic confirmationModerate; supported by indirect evidence and service experience
Formal assessment for higher-risk patientsASA III-IV, frailty, unstable systemic disease, complex medications or airway concernsStrong; consistent with perioperative medicine principles
Do not rely on ASA aloneAdd comorbidity, frailty, functional capacity and medication reviewStrong; ASA limitations are well documented
Prospective auditTrack clinical, operational, economic and patient-reported outcomesEssential for governance and generalisability
Digital triage with oversightUse electronic questionnaires and EPR integration; retain clinician reviewEmerging; promising but requires validation
