A catalogue of failings have been uncovered at two NHS hospitals after seven babies and three mothers died there in the space of just eight months. Independent investigators were called into Royal Oldham after the deaths of four babies and two mothers, and North Manchester General after the deaths of another three babies and one mother. Lisa Parkisson, 35, died at Oldham Royal 48 hours after giving birth in April this year, while newborn Thomas Beaty died at the same hospital in June after doctors pushed him back into the womb during birth. Lisa Parkisson, 35, (left with son Zac) died 48 hours after giving birth at Oldham Royal in June last year. Thomas Beaty (right) died from  at the same hospital after doctors forced him back into the womb . A summary of the investigation, which was kept secret from the families of the dead until now, has been seen by MailOnline and found 'notable absence of clinical leadership' in the maternity wards, and a 'failure to adequately plan care' in a number of cases. A team of independent investigators also found risk management was 'below standard' in some cases - though there were no apparent 'deficiencies in care' in the deaths of the three mothers. The report noted that several of the mothers were obese or morbidly obese, which can lead to complications, but that national guidelines for treating overweight people were not followed. Officials also criticised the hospital's own investigations, saying the root cause of the deaths was not always identified, opportunities to learn lessons were not always picked up, and that some recommendations were too general and difficult to measure. All of the deaths are believed to have occurred between December 2013, and July last year. In one case mother Lisa Parkisson, 35, also died 48 hours after giving birth to her son Zac in June this year. In another case newborn Thomas Beaty died from head injuries in April after medics forced him back into the womb during birth. Doctors had also tried and failed to remove him from the womb five times using forceps, despite national guidelines only recommending three attempts. While his death was not included in the review, staff at North Pennine Acute Hospitals NHS Trust, which controls the two hospitals, have asked investigators to look into it. Martin Beaty, the father of Thomas, said: 'Ten deaths in eight months is sickening. But I'm not surprised. Independent investigators found failings in care and hospital leadership at Oldham Royal following the deaths of four babies and two mothers there in eight months . The report, which also looked into the deaths of three babies and another mother at North Manchester General, found that national guidelines for treating obese mothers were also not followed . 'The standard of care we received during and after Thomas died gives me zero confidence in their organisation, structure and accountability. 'I'm angry we were not informed [about the report], even if out of courtesy. It feels like they're trying to cover each other's backs. 'But I'm fully behind any action that makes sure this sort of thing is prevented in the future.' Pennine Acute is in the process of producing an action plan based on the recommendations from the findings. They include strengthening clinical leadership and risk management, making sure enough staff are on duty to ensure safety and reviewing the process for employing temporary locum doctors. Royal Oldham Hospital's new maternity unit, children's unit and neonatal intensive care unit opened in December 2012. The £44m facility became one of three specialist Greater Manchester neonatal centres as part of a controversial £120m shake-up which saw maternity units shut in Bury, Rochdale and Salford. Gill Harris, Chief Nurse at Pennine Acute, said: 'The Trust is always keen to learn and to improve care. We commissioned a review by experts from outside the Trust to look at the details of a small number of maternity cases at our hospitals. 'We are now considering that report and are developing a number of actions as a result to make some improvements to ensure we continue to provide the best quality of care for our patients. 'We deliver 10,000 babies each year and would like to reassure families about the safety of maternity services at our hospitals, but if any expectant mother has a concern they can contact their designated midwife to discuss this.' A spokeswoman for the Care Quality Commission, the health regulator, said: 'CQC is aware that Pennine Acute Hospitals NHS Trust has recently initiated an external review into its maternity services and we are in close liaison with the trust, NHS England and local CCG regarding the review findings.'
