Investigation and inquest
On 7th November 2017 an investigation into the death of Andrew Robert Frank Clegg was commenced. The investigation concluded at the end of the inquest on 28th March 2019. The conclusion of the inquest jury was that the deceased died from legionella pneumonia as a result of an accident.
Circumstances of the death
The deceased, who was aged 56, was a vulnerable individual as a result of corticobasilar degeneration. He was resident in a recently constructed specialist care home. The care home had been constructed with little attention to water safety. There were long runs of pipes and with hot and cold-water pipes set in close parallel proximity, creating a potential for heat exchange. Over a period of time legionella bacteria colonised parts of the water system and the deceased was infected with a fatal outcome.
Coroner’s concerns
1. Expert evidence suggested that architects designing care homes and healthcare premises, rarely take into account the need for water safety. In combating the risk of a proliferation of legionella bacteria, it is desirable, among other things, to design a water system with short pipe runs and with areas of maximum water usage established at the end of pipe runs to ensure a regular flushing of the pipework. Legionella bacteria, flourishing as it does at temperatures in excess of 20 degrees centigrade, precautions need to be taken to avoid heat exchange between hot and cold-water pipes, calling for cold-water pipes to be set at a distance from hot-water pipes rather than being run in parallel.
2. Care homes and other healthcare premises are regularly inspected by the Care Quality Commission. In recent years the inspection regime has included a duty on inspectors to check on water safety. Expert evidence at the inquest suggested that inspectors lacked training to help them identify risks relating to potential legionella infection.
