Polypharmacy is common among older patients with common diseases. There is a strong need for evaluation management and consultation services of polypharmacy among older patients from medical workers, patients and their families. However, the functional design of how to scientifically and accurately manage services and consultations based on Internet technology for different categories of users has not been adequately studied.

To conduct investigation on the design of the service functions and methods of platform for evaluation management and consultation services of polypharmacy among older patients for healthcare professionals, taking the Internet services oriented to improve irrational drug use and reduce drug-related adverse events in older patients as a new idea.

Healthcare professionals from medical institutions participating in the National Key Research and Development Program (Multiple Drug Use Risk Management for Common Diseases of the Elderly) from 2021-02-20 to 2021-03-06 were selected as research subjects, the self-designed Questionnaire on Platform for Evaluation Management and Consultation Services of Polypharmacy among Older Patients Needs of Healthcare Professionals focusing on the necessity, operation mode and function of the platform were distributed. Principal component analysis was used to extract common factors for each platform function, and further factor rotation was performed using Kaiser's normalized maximum variance method, and the mean values of each factor score were ranked to explain the relative importance of each factor.

A total of 548 valid research questionnaires were collected in this study with recovery rate of 100.00%. The cumulative total variance explained by the third factor in the sum of squared factor extracted for the 8 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, adverse drug reactions record and analysis) was 77.036%. The 8 platform functions were finally extracted into 3 factors, named as reminder factor (F1) , evaluation factor (F2) , and adverse analysis factor (F3) , and the ranking of the mean values of the 3 factors in descending order was F1 (mean factor score of 2.977) , F2 (mean factor score of 0.118) , and F3 (mean factor score of 0.112) .

From the perspective of healthcare professionals, reminder, evaluation and adverse analysis are the main operation modes and core functions of the platform for evaluation management and consultation services of polypharmacy among older patients, with reminder-related functions as the most important functions, which will provide substantial help to ensure the effective contribution of the platform to the construction of polypharmacy risk monitoring and control system for common diseases of the elderly in China.

老年常见病患者多重用药情况普遍存在。医务工作者、患者及其家属对于老年患者多重用药的评价管理与咨询服务均有强烈需求，但是针对不同类别用户，如何科学、准确地进行依托互联网技术的管理服务和咨询功能的设计，并未得到充分研究。

以开展面向改善老年人的不合理用药问题及减少老年患者的药物相关不良事件的互联网服务为新思路，面向医疗专业人员进行老年患者多重用药评价管理与咨询服务平台服务功能和方式的设计调研。

2021-02-20—03-06，以国家重点研发计划"老年常见病多重用药风险管控"项目参与医疗机构的医疗专业人员为研究对象，并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必要性、平台运行方式和平台功能而自行设计的"面向医疗专业人员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。

本研究面向医疗专业人员共采集有效调研问卷548份，问卷有效回收率为100.00%。8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、药品不良反应记录与分析）的因子提取载荷平方和中前3个因子的累积方差解释率为77.036%；8项平台功能最终提取为3个因子，分别命名为提醒因子（F1）、评价因子（F2）、不良分析因子（F3），3个因子按因子得分均值由高到低排序依次为F1（因子得分均值为2.977）、F2（因子得分均值为0.118）、F3（因子得分均值为0.112）。

从医疗专业人员角度来看，提醒、评价、不良分析为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，提醒相关功能是该平台最重要的功能。这将为确保该平台在以后的运行中能切实为我国老年常见病患者多重用药风险监测与管控体系的构建提供实质性帮助。
