To describe the relation between research evidence and local obstetric unit policy for specific areas of care and to explore clinicians' views about the reasons for any discrepancies identified.
An independent evaluation of a project undertaken by a district maternity services liaison committee (MSLC) to promote evidence based maternity care in specific areas of care. The evaluation involved a combination of qualitative methodologies including documentary analysis, non-participant observation, semi-structured interviews, and self completed open ended questionnaires.
One English health district with three obstetric units.
Congruence between unit policies and research evidence in specific areas of care. Views expressed by unit staff concerning the reasons for any discrepancies identified. Consistency between staff views within and between units. Unit attitudes to modification of discrepant policies and details of any subsequent changes made.
Of the 12 unit policies considered, seven were consistent with the research evidence. In all cases in which unit policy did not reflect the evidence, provider unit staff thought that the differences were justified. In several cases there were substantive differences of view between staff in different units. No differences of view were expressed between staff in the same unit. There were three different types of concern about the research evidence and the problems of using it as a basis for deciding unit policy. These were: concerns about the adequacy or completeness of the evidence; concerns about the applicability of the evidence in the local setting; and concerns about local capacity to act on the evidence. At the time of the project, none of the units expressed any intention of modifying the policies under discussion. Subsequently, two of them did make changes of this sort.
The results suggest the need for further research to ascertain what factors may produce such varying assessments of the validity and adequacy of particular sets of research findings as were found between clinicians in this study and to understand what considerations other than views about evidence may affect decisions to alter clinical policy.
When clinicians have clear reasons for not following research evidence, two contrasting responses are possible. One is to take the view that the clinicians are mistaken, and seek to change their attitudes or persuade them to change their behaviour regardless of their views. An alternative response is to accept that the concerns they express may be legitimate and consider how their doubts may be addressed. The challenge is to recognise which response is preferable in any particular situation.
描述特定护理领域的研究证据与当地产科单位政策之间的关系,并探讨临床医生对所发现的任何差异原因的看法。
对一个由地区产妇服务联络委员会(MSLC)开展的项目进行独立评估,该项目旨在促进特定护理领域基于证据的产妇护理。评估采用了多种定性方法,包括文献分析、非参与观察、半结构化访谈和自我填写的开放式问卷。
英国一个有三个产科单位的卫生区。
特定护理领域单位政策与研究证据之间的一致性。单位工作人员对所发现的任何差异原因的看法。各单位内部及不同单位之间工作人员看法的一致性。单位对修改不一致政策的态度以及随后所做任何更改的细节。
在所考虑的12项单位政策中,7项与研究证据一致。在单位政策未反映证据的所有情况下,提供服务的单位工作人员认为这些差异是合理的。在几个案例中,不同单位的工作人员之间存在实质性的观点差异。同一单位的工作人员之间未表达出观点差异。对研究证据以及将其用作决定单位政策基础的问题存在三种不同类型的担忧。这些担忧是:对证据充分性或完整性的担忧;对证据在当地环境适用性的担忧;以及对当地根据证据采取行动能力的担忧。在项目开展时,没有一个单位表示有修改所讨论政策的意图。随后,其中两个单位确实进行了此类更改。
结果表明需要进一步研究,以确定哪些因素可能导致本研究中临床医生对特定研究结果的有效性和充分性产生如此不同的评估,并了解除了对证据的看法之外,还有哪些因素可能影响改变临床政策的决策。
当临床医生有明确理由不遵循研究证据时,可能会有两种截然不同的反应。一种观点认为临床医生是错误的,并试图改变他们的态度或说服他们改变行为,而不顾他们的观点。另一种反应是接受他们表达的担忧可能是合理的,并考虑如何解决他们的疑虑。挑战在于认识到在任何特定情况下哪种反应更可取。
