A 47-yr-old teacher, Ms. Heidi Fox comes to see you in A&E. She seems exhausted and tired with dark circles under her eyes. She tells you that since she returned from Senegal 5 days ago she has been suffering from diffuse headaches on and off. She has had temperatures up to 39.6°C rectally, but overall with great undulation. Her GP prescribed Paracetamol which did not help at all. He also took blood and she shows you the results: (Normal values in parenthesis): Haemoglobin 9.5 g/dl (12-16) Erythrocytes 3.8 T/l (3.9-5.3) Haematocrit 35% (35-47) MCV 92 fl (78-98) MCH 32 pg (28-34) Leucocytes 2.4 G/l (4-11) Platelets 75 G/l (150-400) Sodium 141 mmol/l (135-150) Potassium 4.4 mmol/l (3.5-5.5) Creatinine 1.8 mg/dl GPT 98 U/L (5-19) GOT 76 U/l (5-15) GGT 80 U/l (<28) LDH 440 U/l (80-240) Bilirubin 3.2 mg/dl (<1.0) TPZ (Quick) 85% (70-100) aPTT 25 s (20-35) Because she has been to Senegal you ask a few more questions and Mrs. Fox says that she had shots for yellow fever and hepatitis and took malaria prophylaxis (Chloroquin). You perform a blood film and Malaria tropica with a parasite density of >2 percent is diagnosed. Due to the laboratory findings this is classified as complicated malaria. Mrs. Fox is transferred to ICU and started on i.v. quinine and doxycycline.

Choices, consequences and branching Rather too obvious A 47-yr-old teacher, Ms. Heidi Fox comes to see you in A&E. She seems exhausted and tired with dark circles under her eyes. What would you like to do now? • Ask about travel history • Complete medical history • Proceed to examination
Choices, consequences and branching Clearly states what has been done • You chose to start the examination. • This is the wrong response. Please try again. • Ask about travel history • Complete medical history • Proceed to examination Instant negative feedback - no learning
Presenting problem Travel More history Examination
Branching • Allows real choices that make a difference • Learning from having to make a choice • Learning from the consequences
Choosing a case Relevant to the user and course In an area you know Enough choices to make
Starting - ideal pathway Presents with fever + headache Travel Examination Thick/thin film Improving on Quinine
Developing choices Presents with fever + headache Travel Lumbar puncture Examination CT scan Thick/thin film Symptomatic management Improving on Quinine
Developing choices • Realistic • Related to learning objectives • Cued by text • Must require thought by player or players
Consequences The logical result of your choice Potent promotor of learning Allow realism in the VP Exponential increase in VP complexity
Consequences Model real life - some mistakes can be redeemed multiple mistakes often disastrous
Narrative • To give clear instructions for the player • To involve the player - emotionally, intellectually • To make choices taxing NOT to waffle!
