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.
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.
United Kingdom and Republic of Ireland.
Nominal group composed of 10 doctors (8 consultants, 2 trainees) and 2 nurses.
Level of support (median) and level of agreement (mean absolute deviation from the median) derived from a 9 point Likert scale.
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.
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.
测试运用名义群体技术确定重症监护临床及卫生服务研究重点的可行性,并检验该群体观点的代表性。
通过全国性调查生成主题;运用名义群体技术达成共识水平;通过调查检验结果的代表性。
英国和爱尔兰共和国。
由10名医生(8名顾问医生、2名实习医生)和2名护士组成的名义群体。
采用9分李克特量表得出的支持水平(中位数)和一致水平(与中位数的平均绝对偏差)。
在联系的325个重症监护病房中,187个(58%)做出回应,提供了约1000条研究建议。名义群体审议的106个最常被提及的主题中,37个获得强烈支持,48个获得中度支持,21个获得微弱支持。群体会议后达成了更多共识——与中位数的平均绝对偏差的总体平均值从1.41降至1.26。该群体的观点代表了更广泛的重症监护医护人员群体的观点(r = 0.73,P < 0.01)。教学医院和非教学医院工作人员的观点没有显著差异。在获得最强烈支持的37个主题中,24个与重症监护的组织方面有关,只有13个与技术评估或临床研究有关。
名义群体技术在确定临床医生的研究重点方面是可行且可靠的。这种方法比研究资助机构使用的传统方法更民主、更透明。结果表明,临床医生认为研究提供和组织服务的最佳方式是高度优先事项。
