Lesson 1Laboratory tests: CBC, CRP, basic metabolic panel, pregnancy test in females, urinalysis and interpretationDetails key laboratory tests in suspected appendicitis, including CBC, CRP, metabolic panel, pregnancy testing, and urinalysis, with emphasis on result patterns, diagnostic value, limitations, and integration with clinical findings for accurate diagnosis.
CBC patterns and leukocytosis thresholdsCRP trends and prognostic implicationsElectrolytes, renal function, and dehydrationPregnancy testing and ectopic exclusionUrinalysis to distinguish urinary pathologyCombining lab data with clinical assessmentLesson 2Targeted physical examination: inspection, auscultation, palpation, percussion, rebound, Rovsing's, psoas and obturator signsCovers a stepwise abdominal exam for suspected appendicitis, including inspection, auscultation, palpation, percussion, and specific manoeuvres such as Rovsing, psoas, and obturator tests, with technique tips and interpretation in patient care.

Character, onset, and pain migrationAssociated GI and systemic symptomsUrinary and renal symptom screeningMenstrual, sexual, and obstetric historyMedication, comorbidity, and surgery historyRed flag features requiring urgent actionLesson 6Clinical decision-making for borderline or atypical presentations and when to consult surgery or senior reviewAddresses decision-making in borderline or atypical appendicitis, including equivocal scores or imaging, use of observation units, repeat exams, shared decision-making, and clear thresholds for surgical or senior consultation to ensure patient safety.
Recognizing atypical symptom patternsManaging equivocal lab or imaging resultsUse of observation and serial examinationsDocumentation and safety-netting adviceWhen to involve senior or surgical reviewCommunicating uncertainty with patientsLesson 7Diagnostic pathways and scoring systems: Alvarado score, Appendicitis Inflammatory Response (AIR) score, when to use observation vs imagingExplores structured diagnostic pathways using Alvarado and AIR scores, clarifying cutoffs, risk stratification, and how to choose observation, serial exams, or imaging to minimise missed appendicitis and unnecessary surgery in clinical settings.
Components of the Alvarado scoreAIR score variables and weightingRisk categories and score cutoffsWhen to observe with serial examsWhen to proceed directly to imagingPathways for paediatric and elderly patientsLesson 8Imaging choices and interpretation: ultrasound findings in appendicitis, graded-compression technique, CT abdomen pelvis with IV contrast indications and key findingsReviews imaging options for suspected appendicitis, emphasising graded-compression ultrasound, CT abdomen pelvis with IV contrast, and selective MRI, with indications, key diagnostic signs, limitations, and radiation and contrast safety issues for safe use.
