We asked NHS England whether it was concerned about the assumptions and if switching to wards with single rooms only was safe. It told us that it was working with the NHP team and that Hospital 2.0 must be fit for purpose and thoroughly tested. It also wanted services in community, primary care and social care to change in a way that would support the aim of reducing the time patients spend in hospital.37 Regarding the safety of single rooms, NHS England assured us that new hospitals could safely monitor and oversee single rooms by adapting their clinical models of care. Some other developed countries already have single rooms as standard and in some it is a legal requirement.38 NHS England acknowledged that there would need to be a change in staff mix, and potentially an increase in staff numbers, to cope with the new single-room layout.39 32 Qq 61, 66; C&AG’s Report, para 3.14 33 C&AG’s Report, para 3.14 34 C&AG’s Report, para 3.14 35 NHP0005 36 Qq 61–66 37 Qq 65, 74 38 Q 69 39 Q 70 14 The New Hospital Programme 2 Dealing with reinforced autoclaved aerated concrete (RAAC) and transparency of selection Dealing with RAAC
