Warning over heated birth pools as baby gets Legionnaires’ disease

HEALTH BOSSES are warning against using a type of heated birthing pool at home after a baby born in one was infected with Legionnaires’ disease.

Public Health England (PHE) and NHS England are temporarily advising against the use of pools which have built-in heaters and recirculation pumps and can be filled up two weeks before the birth.

The alert comes after a case of the Legionnaires’ lung disease was identified in a baby born in the specific type of birthing pool at home. The child is in intensive care in hospital.

It is the first reported case of Legionnaires’ disease linked to a birthing pool in England, PHE said.

Samples taken from the birthing pool used confirmed the presence of legionella bacteria, which causes the disease.

Experts are carrying out tests to establish if it is the same strain as that which infected the baby.

Professor Nick Phin, PHE’s head of Legionnaires’ disease, said: “This is an extremely unusual situation, which we are taking very seriously.

“As a precaution, we advise that heated birthing pools, filled in advance of labour and where the temperature is then maintained by use of a heater and pump, are not used in the home setting, while we investigate further and until definitive advice on disinfection and safety is available.”

NHS England issued a Patient Safety Alert to notify the healthcare system and midwives in particular of the possible risk associated with the use of the heated birthing pools at home.

The alert recommends that heated birthing pools are not used for labour or birth. A full risk assessment is being carried out in the meantime.

Heated pools from the supplier involved in the incident have been recalled, PHE said. There are about 10 firms which supply the specific pools and each have between two and 14, which they loan out.

The pools are typically delivered about a fortnight before the expected delivery date and filled from the domestic hot water supply.

The temperature is then maintained by a pump and heater until labour and delivery, with the companies recommending various disinfection regimes.

PHE said the majority of birthing pools used at home are filled from domestic hot water systems at the time of labour and these do not pose the same risk and are not included in the alert.

Prof Phin said: “We do not have concerns about purchased or hired pools that are filled from domestic hot water supplies at the onset of labour, provided that any pumps are used solely for pool emptying.”

Louise Silverton, director for midwifery at the Royal College of Midwives, said: “Women planning birth at home using a traditional pool that is filled when the woman is in labour or using a fixed pool in an NHS unit are not affected by this alert and should not be concerned.

“Birthing pools in hospitals are subject to stringent infection control procedures and monitoring.”

Legionnaires’ disease is extremely rare in children, with only one case in youngsters aged up to nine in England between 1990 and 2011. Although there were two cases reported in Italy and Japan several years ago, it is the first reported case of Legionnaires’ disease linked to a birthing pool in England.
