The task

Ask her to continue Ms Pappas's dietary management and review her blood glucose levels. Address the letter to Ms Thandiwe Nikolaidis, Dietitian, Antenatal Clinic, Maternity Outpatients Department, 40 Riverside Road, Brisbane QLD 4000. In your answer: expand the relevant notes into complete sentences; do not use note form; use letter format. The body of the letter should be approximately 180–200 words.

Length: the body of the letter should be about 180–200 words. You have 45 minutes in the test: 5 minutes to read, 40 to write. Letter type: Referral letter.

Who is reading, and what do they need?

Ms Nikolaidis is a Brisbane antenatal dietitian who has not met the patient and takes over dietary care after 31/10. She needs current glucose status, the diet plan in place, the pending treatment review and the requested timeframe. Obstetric details are sent separately, so keep the content dietetic and focused.

What to include

Selection is the skill the Content and Conciseness criteria reward. These notes earn their place:

Case noteWhy it belongs
Fasting BGLs 5.2–5.6 on 4 of last 7 days, target ≤5.0The one unresolved glucose problem despite the supper snack. It is the main reason the Brisbane dietitian needs to review readings.
Post-meal BGLs 6.1–7.2, all within ≤7.4 target over 7 daysShows the breakfast change is working and should be maintained. It also gives the reader the agreed targets to continue using.
3 small meals + 3 snacks, low GI, protein each mealThis is the current plan the reader is asked to continue. Summarise it briefly instead of listing the earlier diet history in detail.
Review 24/10 to consider metformin or insulinA possible treatment change before the move, whose outcome is unknown when writing. The reader needs to know Melbourne continues BGL review until Brisbane care is confirmed.
Lacto-ovo vegetarian; iron deficiency at 20/40, daily oral ironAffects protein sources and food advice, so a dietitian taking over needs it. Keep it to one brief mention.
Weight 84 kg pre-pregnancy (BMI 31), 91 kg todayWeight gain is part of the dietetic picture for the new dietitian. It is also baseline data for her own monitoring.
Food and BGL diary in phone app; happy to share recordsGives the reader a practical way to see the readings and diet. It also shows the patient is engaged.
Request appointment within 1/52 of arrival (by 07/11)This is the action requested, and the date follows from the move on 31/10.

What to leave out or compress

Case noteWhy it goes
Mother-in-law says she 'brought this on herself' with fruitFamily opinion rather than clinical information. Repeating it adds nothing for dietary management and could mislead about her diet.
Pottery classes; graphic designer working remotely; partner's projectLifestyle and work detail that does not change dietary management. The reason for the move needs at most a few words.
Complained clinic waits too long; receptionist 'rude'A service complaint, irrelevant to the Brisbane dietitian's task.
Growth scan normal, BP normal at 20/10 reviewTrap: it looks clinically relevant, but the obstetric team sends the obstetric summary separately, so the reader does not need it here.
Appendicectomy age 12; allergies nilRemote surgical history with no bearing on nutrition or glucose management.

A paragraph plan for this case

Open with the referral purpose, the patient's move date and her GDM diagnosis. Give the dietetic management and glucose progress next, separating the fasting problem from the readings within target. Close with the 24/10 review, who covers until Brisbane care is confirmed, the appointment date requested and the postnatal follow-up.

Where candidates slip on this task

  • Keep fasting and post-meal readings distinct. Only fasting values are above target, on 4 of the last 7 days, so avoid describing her control as poor overall.
  • The 24/10 review outcome is unknown today. Say that metformin or insulin will be considered, not that either will start, and make clear Melbourne continues review until Brisbane care is confirmed.
  • Give the actual date for the appointment request (by 07/11), worked out from arrival on 31/10, rather than only 'within a week'. Do not calculate gestation at arrival.

Questions about this task

Should the patient's anxiety about insulin be included?

It is optional. The reader may benefit from knowing, but it is not needed for the requested actions. The review on 24/10 is only considering metformin or insulin, so avoid implying insulin is planned.

How much of the earlier diet history is needed?

Only enough to show what changed and why it matters. The reader needs the current plan and the glucose response, not the full initial diet history or each appointment date.
