Legionnaires' warning issued over type of home birthing pool
A safety alert has been issued that warns 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.
“This is an extremely unusual situation, which we are taking very seriously”
The safety 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 around 10 firms which supply the specific pools and each have between two and 14, which they loan out.
The pools are typically delivered around 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.
Professor 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.
“PHE and relevant local authorities are investigating the infection control measures required for this type of birthing pool and local authorities will be working with the small number of companies who supply these heated birthing pools for use at home.”
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. Home birthing pools filled during labour come with disposable liners and are only in place for a relatively short time period, reducing opportunity for bacterial growth.”
Legionnaires’ disease is extremely rare in children, with only one case in youngsters aged up to nine in England between 1990 and 2011.
“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”
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.
Patients become infected with the bacteria through inhalation of contaminated water droplets. The infection does not spread from person to person.
The disease is a severe form of pneumonia which affects around 350 to 400 people each year in England and Wales. The majority of cases involve older patients.
NHS information about the condition says that most people make a full recovery but “in some cases it can lead to further, life-threatening, problems”.
Midwives and every local authority in the country are being contacted to see if they use the specific pools provided by any of the companies that supply them.
If the pools are currently out for use, councils and midwives should take steps to get them back, a PHE spokeswoman said.
