Half of families suffer in hospital, study finds YouGov surveyed 2000 people in February. More than two-thirds - 68 per cent - said trusts must be forced to publicly reveal their errors. Patients Association Chief Executive Katherine Murphy said: "This is yet another indicator, following the drop in patient satisfaction and the damning publication of the Francis report, that care in the NHS is not at the standards that patients have a right to expect." The figures come in the wake of the Mid Staffs scandal, in which patients were found to be left drinking from flower vases because they were so neglected. NHS casualty units have become like "warzones," with medics fighting a losing battle to cope with an increasing tide of patients, one of Britain's most senior Accident & Emergency doctors has warned today. David Prior, head of the Care Quality Commission (CQC), recently said almost half of hospitals providing care was either poor or "not terribly" good. The CQC identified about 45 hospitals which have had serious problems, and said these hospitals will now be a priority for inspection. Mr Prior said health service could not give a "cast iron guarantee" that there would never be another scandal like Mid Staffordshire, where more than 1,000 patients may have died needlessly. . The Patients Association said it was vital the NHS is transparent and acts quickly to make changes where they have been identified. Experiences of poor care may also be having an impact on trust in political partieson the issue of the NHS. The most trusted party was Labour, at 34 per cent, followed by the next popular answer of "none of them" at 30 per cent. The Conservatives came just above the Liberal Democrats, being chosen by 18 per cent of respondents as the party they "most trusted on the issue of the NHS." The results of the poll come after the Daily Telegraph revealed dozens of NHS doctors are avoiding being investigated by the General Medical Council, despite repeated claims they put patients at risk and hospitals paying out compensation to patients for their mistakes. This found more than 200 doctors have had more than two allegations of clinical negligence lodged against them - but just eight were referred to the official watchdog. In some cases consultants had as many as ten, 12 and 13 clinical negligence allegations against them and in a lot of cases doctors still kept their jobs in spite of compensation being paid.
