“…Studies to date suggest that quality has improved for some conditions (Cooper, Gibbons, Jones, & Mcguire, ; Gaynor et al, ; Gravelle et al, ; Moscelli, Gravelle, Siciliani, & Santos, ), but may have fallen for others (Moscelli, Gravelle, & Siciliani, ; Skellern, ). Account must also be taken of the direct costs of implementing the policy change, such as some proportion of the £280m spent by the NHS up to 2012 to set‐up and run the electronic “Choose and Book” system to facilitate patients' participation in their hospital referrals (Department of Health, , Dusheiko & Gravelle, ). There are also other potentially welfare‐increasing policy tools available, such as direct financial incentives for providers (Meacock, Kristensen, & Sutton, ), regulation, targets (Propper et al, ), and organisational and budgetary changes (Mason, Goddard, Weatherly, & Chalkley, ; Siciliani, Chalkley, & Gravelle, ), which can be used as substitutes or complements to changes in competition among providers.…”
