Our research team has previously conducted investigation on platform for evaluation management and consultation services of polypharmacy among older patients needs of healthcare professionals to ensure a close association between the design and development of the platform and actual needs. However, the awareness of the risks associated with polypharmacy in the elderly and needs of manage services and consultations based on Internet among general population have been rarely reported in China.

To understand the awareness of platform for evaluation management and consultation services of polypharmacy among older patients of general population, so as to further explore the operation mode of the platform and provide guidance for its improvement and refinement.

The self-designed Questionnaire on Platform for Evaluation Management and Consultation Services of Polypharmacy among Older Patients Needs of General Population focusing on the operation mode and importance of each function were distributed to the users of HeFen Club platform of China Mobile from 2021-09-29 to 2021-10-09, using HeFen Club WeChat public platform of China Mobile as the investigation platform and web-based questionnaire survey for general population as the investigation method. Principal component analysis was used to extract common factors for each platform function, and Kaiser's normalized maximum variance method was further used to rotate the factors and rank the mean scores of each factor to explain the relative importance of each factor.

A total of 29 502 valid questionnaires were collected in this study with a recovery rate of 94.89%. The cumulative total variance explained by the fourth factor in the sum of squared factor extracted for the 12 platform functions (patient compliance evaluation, prescription appropriateness evaluation, prescription economy evaluation, medication administration notification and reminder, medication administration precautions, medication administration record management, potential medication problem reminder, manual real-time consultation, manual non-real-time consultation, self-service query, medication administration reminder, and record analysis) was 76.791%; The 12 platform functions were finally extracted into 4 factors, named as reminder factor (F1) , evaluation factor (F2) , query and record factor (F3) and consultation factor (F4) , and the ranking of the mean values of the 4 factors in descending order was F2 (mean factor score of 0.507) , F1 (mean factor score of 0.457) , F3 (mean factor score of 0.430) , and F4 (mean factor score of 0.253) .

Nearly 90.00% of the respondents believe that older adults with multiple common diseases are at risk of polypharmacy and need a platform for management and consultation services of polypharmacy. From a public perspective, reminder, evaluation, querying and record, consultation are the main operation modes and core functions of the platform for evaluation management and consultation services of polypharmacy among older patients.

为确保老年患者多重用药评价管理与咨询服务平台的设计和开发与实际需求紧密相连，本课题组既往面向医疗专业人员群体开展了老年多重用药管理评价与咨询平台需求的调研工作，但目前国内鲜有研究探索大众人群对老年人多重用药风险的认知程度，以及其对基于互联网医疗进行多重用药管理评价和咨询的需求现状。

了解大众人群对老年多重用药管理评价与咨询平台的认知现状，以进一步探索老年患者多重用药评价管理与咨询服务平台的运行方式，为老年患者多重用药评价管理与咨询服务平台的改进与完善提供指导性意见。

2021-09-29—10-09，面向大众人群采用网络问卷调查法，以中国移动和粉俱乐部微信公众号平台为调研渠道，对中国移动和粉俱乐部用户开展调研，向其发放针对老年患者多重用药评价管理与咨询服务平台的运行方式、各功能重要性等问题而自行设计的"面向大众人群的老年患者多重用药评价管理与咨询服务平台需求调研问卷"。采用主成分分析方法对各平台功能提取公因子，进一步采用Kaiser正态化最大方差法进行因子旋转，并对各因子得分均值进行排序，以此来解释各因子的相对重要性。

本研究面向大众人群共采集有效调研问卷29 502份，问卷有效回收率为94.89%。12项平台功能（患者依从性评价、处方适宜性评价、处方经济性评价、服药告知与提醒、服药注意事项、服药记录管理、潜在用药问题提醒、人工实时咨询、人工非实时咨询、自助查询、提醒服药、记录分析）的因子提取载荷平方和中前4个因子的累积方差解释率为76.791%；12项平台功能最终提取为4个因子，分别命名为提醒因子（F1）、评价因子（F2）、查询与记录因子（F3）和咨询因子（F4），4个因子得分均值由高到低排序依次为F2（因子得分均值为0.507）、F1（因子得分均值为0.457）、F3（因子得分均值为0.430）、F4（因子得分均值为0.253）。

接近90.00%的大众人群认为患有多种常见病的老年人在用药方面存在风险，需要相关平台开展多重用药方面的辅助管理与咨询服务。大众人群视角下，提醒、评价、查询与记录、咨询是老年患者多重用药评价管理与咨询服务平台主要运行方式与核心功能。
