useful checklist <strong>and</strong> would perhaps fit here. The task then is <strong>to</strong> test for the extent <strong>to</strong><br />

which a wide range <strong>of</strong> clinical disciplines will use such strategy in practice, <strong>and</strong><br />

explicitly so in documentation, <strong>and</strong> whether it does appear <strong>to</strong> be useful. The real value<br />

<strong>of</strong> multi-disciplinary - indeed multi-person - input at this task has never been<br />

satisfac<strong>to</strong>rily established. Should an additive model be applied <strong>to</strong> what is available, or<br />

should it be an averaging model, or a consensus one? What difference <strong>to</strong> an assessment<br />

statement does each route make? In turn, what difference does this make in practice?<br />

Work on polarisation in groups (Moscovici <strong>and</strong> Zavalloni, 1969; Myers <strong>and</strong> Lamm,<br />

1976) suggests that there are no grounds for complacency in assumptions about<br />

multidisciplinary consensus being useful.<br />

There remains a place for naturalistic management studies. As methodology improves<br />

<strong>and</strong> satisfac<strong>to</strong>ry allowance can be made for relative times at risk, there is still much <strong>to</strong><br />

learn in long-term follow-up. The case for adding more experimental designs is,<br />

however, also strong, as the 'second generation' studies from the USA noted above also<br />

show.<br />
