Accidental overdose of hospital patients with paracetamol sparks investigation

Patients have been significantly harmed, including suffering permanent damage to their liver, after being given accidental overdoses of paracetamol in hospital.

The NHS safety watchdog the Healthcare Safety Investigation Branch (HSIB) has now launched a national investigation after a number of incidents where adults with a low bodyweight were given too much paracetamol through an infusion, or IV drip, directly into their bloodstream.

The Independent understands there were three incidents reported by NHS staff in 2020 but there have been others in earlier years including the trigger event which sparked HSIB’s probe.

Overdoses of IV paracetamol in both adults and children is a recurring problem. Safety alerts have been repeatedly issued to NHS hospitals over the problem, with one alert in 2010 highlighting more than 200 previous incidents of overdoses.

In 2011 an inquiry into the death of 19-year-old Danielle Welsh, who died from liver failure due to a sustained paracetamol overdose in June 2008, found a junior doctor who prescribed the drug did not know she weighed only 35kg. The inquiry found: “There was a prevailing culture of assumed familiarity with the administration of IV paracetamol, a familiarity derived from the common use of oral paracetamol.”

Now the independent Healthcare Safety Investigation Branch believes the problem of prescribing paracetamol without considering a patients’ weight is still going on.
