She said the trust had reviewed care last year and was making improvements. Nationally, about one in four women was left alone during childbirth when they were worried but the figure rose to almost half of new mothers in Bart's and The London and also in Lewisham Hospital. At least four in 10 women said they were left alone when scared at several hospital trusts: Newham, Barking, Havering and Redbridge, North Middlesex and Barnet and Chase Farm. Other trusts with poor satisfaction ratings among new mothers were The Royal Free in Hampstead, Mayday Healthcare in Croydon, North West London, Kingston, Hammersmith Hospitals and King's College Hospital. Meanwhile, the Standard has found 718 official complaints about maternity care were made in London last year - one per 170 births, compared with one per 254 births nationwide. The rate of complaints fell slightly.
