Needlestick at 9 pm: Prophylaxis Without a Kit or a Report
At 9:10 pm in a 30-bed taluk hospital, a 23-year-old staff nurse recaps a needle after giving an intramuscular injection, and the needle passes through her glove and pierces the pad of her left thumb. It bleeds a little. The patient is a 38-year-old man admitted two days earlier with fever and jaundice; his file has no HIV or hepatitis B report, and he is drowsy, so consent for blood tests is being taken from his brother. The nurse received three doses of hepatitis B vaccine four years ago but has never had her anti-HBs titre checked. The hospital has no post-exposure prophylaxis kit on the ward, the medical officer is off duty but reachable by phone, and the district ART centre opens at 9 am. A colleague suggests washing the wound with spirit and then bleach, and another says to wait for the patient's reports before doing anything.
1. What is the correct immediate wound care? Explain why both colleagues' suggestions are wrong.

Correct care, immediately: wash the wound under running water with soap for about 15 seconds to a minute, allow it to bleed freely under the water, do not scrub or squeeze hard, dry gently, apply povidone-iodine or 70% alcohol, and cover with a waterproof dressing. Then report at once and start the incident form.
Why the colleagues are wrong: bleach is caustic and damages tissue, creating a larger portal for infection; spirit alone does not remove blood and is no substitute for washing. Neither has been shown to reduce HIV transmission. Waiting for the patient's reports wastes the most valuable hours - post-exposure prophylaxis works better the earlier it starts, and the decision rests on a risk assessment, not on waiting. Hard squeezing or sucking does not 'remove' virus and can injure the tissue further.
2. The source patient's HIV and hepatitis B status is unknown and results will take 48 hours. When should HIV prophylaxis start, and what should be done about hepatitis B? Give timings.

HIV: do not wait for the source results. Phone the medical officer now, do a risk assessment, and start triple-drug prophylaxis as soon as possible - ideally within 2 hours and certainly within 72 hours - for 28 days. It is 9:10 pm and the ART centre opens at 9 am, about 12 hours away: still within the window, but call the district hospital or the ART on-call number for a starter pack tonight rather than sleeping on it. Take a baseline HIV test, but never delay prophylaxis for the result.
Hepatitis B: she had three vaccine doses but no anti-HBs titre. Give a booster dose of hepatitis B vaccine as soon as possible (within 24 hours, at most 7 days), and test anti-HBs and HBsAg. If the source is HBsAg positive and she is a non-responder, HBIG is needed within 72 hours. Check tetanus status as well. If the source later tests negative, prophylaxis can be reviewed and stopped after discussion.
3. What must be documented about this incident, and what one change would you recommend to prevent recurrence?
Read the worked answer
Document: date and exact time of injury; what she was doing; device type, gauge and depth; glove use and whether recapping occurred; the source patient's identity, clinical diagnosis and consent for testing; first aid given; risk assessment; prophylaxis prescribed and the time of the first dose; baseline tests; counselling given; follow-up dates; and the incident report sent to the infection control officer and nursing superintendent. Consent or refusal must be recorded, not assumed.
One change to prevent recurrence: ban recapping. Place a puncture-proof sharps container on the medicine trolley at the point of use so the needle is dropped in immediately after the injection, and provide safety-engineered needles where possible. Add annual training on sharps handling and confirm hepatitis B vaccination with a post-vaccination anti-HBs titre for every staff nurse.
