Objectives:
To test the feasibility of using a nominal group technique to establish clinical and health services research priorities in critical care and to test the representativeness of the
group's views.
Design:
Generation of topics by means of a national survey; a nominal group technique to establish the level of consensus; a survey to test the representativeness of the results.
Setting:
United Kingdom and Republic of Ireland.
Subjects:
Nominal group composed of 10 doctors (8 consultants, 2 trainees) and 2 nurses.
Main outcome measure:
Level of support (median) and
level of agreement (mean absolute deviation from the median) derived
from a 9 point Likert scale.
Results:
Of the 325 intensive care units approached, 187 (58%) responded, providing about 1000 suggestions for research. Of
the 106 most frequently suggested topics considered by the nominal
group, 37 attracted strong support, 48 moderate support and
21 weak support. There was more agreement after the group had
met
overall mean of the mean absolute deviations from the median fell
from 1.41 to 1.26. The group's views represented the views of the
wider community of critical care staff (r=0.73, P<0.01). There was no
significant difference in the views of staff from teaching or from
non-teaching hospitals. Of the 37 topics that attracted the strongest
support, 24 were concerned with organisational aspects of critical care
and only 13 with technology assessment or clinical research.
Conclusions:
A nominal group technique is feasible and reliable for determining research priorities among clinicians. This
approach is more democratic and transparent than the traditional methods used by research funding bodies. The results suggest that clinicians perceive research into the best ways of delivering and
organising services as a high priority.
