According to the Professional Standards Authority (PSA) 'it is primarily the professionalism of individuals that keeps the public safe …'. 1 But GPs find it increasingly difficult to exercise professionalism with the current workload pressures. 2 Part of the problem is over-regulation and bureaucracy, and recently NHS England, the Care Quality Commission (CQC), and the General Medical Council (GMC) called for action to lessen the burden. 3 Any reduction will help, but it may prove more important to understand the culture that drives over-regulation. We seem to be locked in a vicious cycle that undermines professionalism. With every stepwise increase in workload comes further micro-management and control, which make matters worse. Only by understanding the mechanics of this damaging cycle, can we change the culture of control to one that makes better use of the most valuable resource in the NHS: the professionalism of its workforce. WHEN CONTROL SYSTEMS BACKFIRE Sanfey and Ahluwalia have described a fearavoidance cycle that emerges whenever a prevailing regulatory culture is seen as oppressive or punitive. 4 Doctors become reluctant to openly investigate and correct flaws in the care they deliver. Without selfcorrection by professionals, regulators feel compelled to impose external controls, which generate yet more fear, and so on. A similar vicious cycle may also be driving up costs. In advanced economies, up to 30% of total healthcare spending can be medically unnecessary. 5 In the UK, defensive practice is rising inexorably, driven largely by fear, 6 and increasing the proportion of unnecessary referrals, investigations, and prescriptions. 7 Economic models however, are very poor at distinguishing necessary from unnecessary healthcare. 5 They interpret the rise in medical interventions as increased patient demand, which means a vicious cycle can develop when methods for controlling expenditure also increase medically unnecessary interventions. Staff and tariff costs were targeted to improve productivity in the first Quality, Innovation, Productivity, and Prevention programme (QIPP) from 2010-2015. Cutting pay causes stress, which together with excessive workload, burnout, and riskaversion is known to generate unnecessary referrals, prescriptions, and investigations. 8,9
