【摘要】：[研究背景]當前,物聯(lián)網作為新一代信息技術廣泛應用于各大領域,在醫(yī)療方面,物聯(lián)網技術具有優(yōu)化醫(yī)療服務模式、提高醫(yī)院營運和管理效率,提高醫(yī)院整體服務水平等多種優(yōu)勢,雖然我國醫(yī)療物聯(lián)網建設正快速開展,但目前還沒有關于醫(yī)療物聯(lián)網水平評價的指標體系和具體應用,醫(yī)療物聯(lián)網建設是一套復雜的系統(tǒng)工程,具體發(fā)展水平及建設效益很難從主觀上把握,因此,迫切需要一套科學權威的評價指標體系。[研究目的]在分析醫(yī)療物聯(lián)網水平評價現狀及存在問題的基礎上,構建一套科學權威的、具有較高信度效度的醫(yī)療物聯(lián)網水平評價體系,來促進醫(yī)療物聯(lián)網建設的規(guī)范化和科學化。[研究方法和研究內容]①本研究通過文獻分析法,查閱國內外醫(yī)療物聯(lián)網評價相關文獻,為評價指標體系提供理論依據,并結合近年來國家頒布的重要政策文件以及領域專家建議,構建初步醫(yī)療物聯(lián)網水平評價指標體系;②通過兩輪德爾菲調查法,邀請領域內15位專家參與評價模型優(yōu)化工作,并從專家積極系數和專家權威系數兩個指標對專家可靠性進行檢驗,利用協(xié)調系數和變異系數檢驗專家一致性,以確保指標體系的權威性、科學性;③運用層次分析法計算指標體系權重;④采用問卷調查法對湖北省10所醫(yī)院開展醫(yī)療物聯(lián)網建設情況調查;⑤利用等級評分法、綜合評分法完成指標量化,并運用極差值法對所有指標數據進行歸一化處理;⑥運用線性加權法計算各調研對象的醫(yī)療物聯(lián)網水平綜合得分;⑦通過計算克朗巴赫a系數來檢驗指標體系的信度,主成分分析法用于檢驗指標體系的效度。[研究結果]構建一套醫(yī)療物聯(lián)網評價指標體系,包括5個一級指標、20個二級指標和85個三級指標,其中一級指標包括醫(yī)療物聯(lián)網保障體系、醫(yī)療物聯(lián)網基礎設施、物聯(lián)網技術應用、醫(yī)療物聯(lián)網信息安全和醫(yī)療物聯(lián)網標準五個維度,所有指標的專家認可度較高,專家評價通過一致性檢驗,兩輪調查的專家協(xié)調系數都在0.5以上,說明評價模型具有一定的權威性和可靠性。通過信度效度檢驗,顯示本指標體系具有較好的一致性信度、內容效度和結構效度,說明本研究的評價模型評價結果是穩(wěn)定的、可靠的。
[Abstract]:[background] at present, the Internet of things, as a new generation of information technology, is widely used in various fields. In the medical field, the Internet of things technology has the advantages of optimizing the medical service mode and improving the efficiency of hospital operation and management. Although the construction of the medical Internet of things is developing rapidly in China, there is no index system and concrete application for evaluating the level of the medical Internet of things. The construction of medical internet of things is a complex system engineering, the concrete development level and the construction benefit are difficult to grasp subjectively, therefore, it is urgent to have a set of scientific and authoritative evaluation index system. [objective] on the basis of analyzing the present situation and existing problems of medical Internet of things evaluation, a set of scientific authoritative medical Internet of things evaluation system with high reliability and validity was constructed. To promote the construction of the medical Internet of things standardized and scientific. [research methods and contents] 1 through literature analysis, this study looked up the relevant literature on the evaluation of the medical internet of things at home and abroad, and provided the theoretical basis for the evaluation index system. Combined with the important policy documents issued by the state in recent years and the suggestions of experts in the field, the preliminary evaluation index system of the level of the medical Internet of things is constructed. (2) through two rounds of Delphi investigation, 15 experts in the field are invited to participate in the evaluation model optimization, and the expert reliability is tested from two indexes of expert positive coefficient and expert authority coefficient. Using the coordination coefficient and variation coefficient to test the consistency of experts to ensure the authority and scientific nature of the index system; (3) Analytic hierarchy process (AHP) was used to calculate the weight of the index system, and (4) the questionnaire survey was used to investigate the construction of the medical internet of things in 10 hospitals in Hubei Province. (5) the index is quantified by grade scoring method and comprehensive scoring method, and all index data are normalized by extreme difference method, and the comprehensive score of medical internet of things is calculated by linear weighting method. 7 the reliability of the index system was tested by calculating the Cronbach a coefficient, and the validity of the index system was tested by principal component analysis. [results] A set of evaluation index system of the medical Internet of things is constructed, which includes 5 primary indicators, 20 secondary indicators and 85 third-level indicators, among which the first-level indicators include the medical Internet of things guarantee system, the medical Internet of things infrastructure. The application of Internet of things technology, the information security of medical Internet of things and the standard of medical Internet of things are five dimensions, the expert recognition degree of all indexes is high, the expert evaluation passes the consistency test, the expert coordination coefficient of the two rounds of investigation is above 0.5. It shows that the evaluation model has certain authority and reliability. The reliability and validity tests show that this index system has good consistency reliability, content validity and structural validity. The evaluation results of the evaluation model are stable and reliable.
