Blood Camp Under Target: Three Donors at the Screening Table
A blood donation camp is held at a Jharkhand block hospital on a Sunday; the target is 60 units, and by 3 pm only 34 have been collected. Twelve donors are still waiting and the last bus leaves at 5 pm. The medical officer asks the technician to 'speed up screening'. Three donors are at the front: Donor A: man, 34, weight 58 kg, haemoglobin by hemoglobinometer 12.1 g/dL, no symptoms, got a forearm tattoo four months ago at a fair. He says he is 'fit and has donated before'. Donor B: woman, 26, weight 54 kg, haemoglobin 13.2 g/dL, donated whole blood 3½ months ago at another camp, no other risk factors. Donor C: man, 45, weight 70 kg, haemoglobin 14.0 g/dL, BP 148/96 mmHg, pulse 102/min and irregular, no symptoms.
1. Decide for each donor and name the binding criterion for the donor you defer.

Donor A: defer. Haemoglobin 12.1 g/dL is below the 12.5 g/dL minimum, and the tattoo is only 4 months old; the tattoo rule requires 12 months. The binding criterion is the tattoo, so the earliest return is about 8 months from now, provided haemoglobin has recovered.
Donor B: accept. She is 26, weighs 54 kg, haemoglobin is 13.2 g/dL, and her last whole-blood donation was 3.5 months ago, satisfying the 3-month interval.
Donor C: defer pending recheck. Pulse 102/min and irregular, and diastolic 96 mmHg, breach donor criteria (pulse 60-100 regular, diastolic up to 100). Let him rest 15-20 minutes and repeat; if still abnormal, defer him for this camp and refer him for blood pressure and pulse assessment. An irregular fast pulse in a 45-year-old deserves a medical look, not a donation.
2. The medical officer says the camp is short of units, so accept Donor A because 12.1 is 'almost 12.5' and the tattoo is 'healed'. How do you respond?

Say no, and explain precisely. Haemoglobin 12.1 is a real cut-off: a donor loses about 450 mL of blood and 200-250 mg of iron, and accepting an anaemic donor risks syncope and worsens iron deficiency, especially in a repeat donor.
A healed tattoo is not the issue. The 12-month rule exists because blood-borne viruses have a window period, and a tattoo done at a fair may have used unsterile equipment. Deferral protects the recipient.
The camp target does not change the criteria; one bad unit can harm a patient and destroy the camp's credibility. Record the reason and the earliest return date, thank the donor, and offer a future appointment. If the medical officer insists, ask for the instruction in writing.
3. Design the next 90 minutes: what can be parallelised and what must never be compressed?
Read the worked answer
Parallelise registration, consent and the donor questionnaire with haemoglobin and vital-sign checks, and queue donors so that the most likely deferrals are screened first - that frees the beds. Fix a closing time of 4:45 pm and tell waiting donors honestly.
Never compress: identity and consent, haemoglobin, pulse and blood pressure, the risk questionnaire, bedside labelling of the bag and samples, and the 15-minute post-donation observation with refreshments. Post-donation observation is where vasovagal reactions are caught.
If some donors will miss the bus, register them for the next camp rather than rushing the ones already on the bed.
