From a report from the cross-bench Centre for Health and the Public Interest:
"The report reveals that over 800 people have died unexpectedly in private hospitals in England during the last four years. Private hospitals are not required to make data on hospital deaths publicly available – unlike their NHS counterparts – making it difficult for the public to understand how safe private hospitals are.
The CHPI report for the first time brings together what is known about patient safety in private hospitals in England:
Between October 2010 and April 2014 802 patients died unexpectedly in private hospitals, and there were 921 serious injuries.
The majority of private hospitals have no intensive care beds, some have no dedicated resuscitation teams, and surgeons and anaesthetists usually work in isolation – without assistant surgeons and anaesthetists in training present.
Although the private hospital sector now gets over a quarter of its income from treating NHS-funded patients, there is significantly less information available to patients about the performance of private hospitals than about the NHS.
It is not possible to establish whether all private hospitals providing NHS care are fulfilling their legal obligation to publish Quality Accounts letting the public know how they are performing.
The report also confirms that the NHS serves as a ‘safety net’ for the private sector. Thousands of people are regularly transferred to NHS hospitals following treatment in private hospitals, with over 2,600 emergency NHS admissions from the private sector in 2012-13."
