The large OXCHECK trial (of a nurse led health check plus health education and follow-up tailored to the level of cardiovascular risk) had only modest effects on cardiovascular events.1 Indeed, more recent literature raises further concerns.2 3 Healthcare professionals’ advice to stop smoking or take more exercise also has frustratingly modest effects.4
All screening programmes are imperfect. Even with generous resources, the call, recall, and follow-up systems require major commitments. Drop outs are substantial. Screening failures will be more common in the more deprived groups, who also experience higher rates of …
