医院住院患者自杀公共环境相关性指标体系的构建

Construction of correlation index system on hospital inpatient suicide and public environment

目的确定医院住院患者自杀公共环境相关性指标体系一级、二级指标的权重,以构建医院住院患者自杀公共环境相关性指标体系.方法2018年1—3月根据入选条件,最终遴选了40名专家为咨询对象.采用德尔菲法对40名专家完成2轮有效函询,展开指标权重的调查,并构建层次结构模型,建立判断矩阵,计算各级指标权重并检验问卷一致率.结果2轮专家函询表回收率分别是100%、100%,专家的权威系数是0.85~0.87,通过一致性检验,最终构建的医院住院患者自杀相关性公共环境指标体系包括2个一级指标(即外部环境相关因素、内部环境相关因素)、12个二级指标及18个三级指标;一级指标权重权重系数分别是0.5406、0.4594;二级指标权重为0.0244~0.2031,三级指标权重为0.0084~0.0583,各判断矩阵的CR值为0~0.0110.结论40名专家权威程度较高,且意见协调度好.通过德尔菲法初步建立了医院住院患者自杀公共环境相关性指标体系,该指标体系具有客观科学可行性,可以为医院有效防控患者自杀,确保患者安全,提供客观、可量化的借鉴依据.

Objective To determine the weights of the primary and secondary index in the correlation index system on the relationship between hospital inpatients suicide and the public environment and to construct the system. Methods From January to March in 2018, 40 experts were finally selected as the consultants according to the admission criteria. The Delphi method was used to complete two rounds of effective inquiry to 40 experts, investigate the index weight, construct the hierarchical structure model, establish the judgment matrix, and to calculate the index weight at all levels and to test the consistency rate of the questionnaire. Results The recovery rates of the two rounds of expert consultation were 100 % and 100%, respectively, and the authority coefficient of the experts was 0.85-0.87. Finally, by consistency testing, the public environmental index system of hospital inpatient suicide related to public environment included 2 primary indexes (i.e. external environmental factors, internal environmental related factors), 12 secondary indicators and 18 tertiary indicators. The weight coefficient of the primary index was 0.540 6-0.459 4, the weight of the secondary index was 0.024 4-0.203 1, the weight of the tertiary index was 0.008 4-0.058 3, and the CR value of each judgment matrix was 0-0.011 0. Conclusions 40 experts have a high degree of authority and good coordination of opinions. Through Delphi method, the public environment correlation index system of hospital inpatient suicide is established. The index system is objective and scientific, and can provide objective quantifiable reference for the hospital in the effective prevention of patients' suicide and ensure the patient safety.
