Factors Influencing Information Service Quality of China Hospital: The Case Study of since 2017 of a Hospital Information Platform in China

Background: As a country with the largest number of netizens around the world, China enjoys improving social information services based on the Internet. With such a large quantity of network users, it is inevitable for China's hospitals at various levels to provide patients and the public with information services by setting up their own official websites. But it is still elusive for the factors affecting the information service quality of China Hospital. Objective: Identifies the factors affecting the information service quality of the case of the Online website of a hospital in China.adding new content to the research fruits in this field. The research can effectively enhance the efficiency of hospital resource utilization, allocating limited resources to most efficient areas and leveling up the information service quality of hospitals to the largest extent. This ultimately improves patient satisfaction. Method: This research investigates the factors affecting the information service quality of the case of a Chinese hospital online website and by means of Delphi method, statistical analysis, and other research methods, formulates the Evaluation Indicator System for the Information Service Quality of the case of the Online website of a hospital in China. The research applies this system to the empirical research on the information service quality of the hospital's website and then makes a comparative analysis between the research results and traffic data of the websites of other hospitals over the same period. Results: By means of the Bivariate Correlation, the author carried out a correlation analysis of the comprehensive evaluations of the information service of the Online website of a hospital in China and the traffic data of the Online website of a hospital in China, including the total traffic, PV and UV. For details of the analysis results, indicates that the correlation coefficient among the three objects is 1, a significant correlation. It also suggests that the comprehensive evaluations of the information service of A Chinese hospital website and the traffic of A Chinese hospital website are positively correlated. The information service quality of China Hospital website is an important component of the hospital's overall service quality. This research on the information service quality of China Hospital website covers the website's service functions, service quality, resources and the front-end and back-end technology systems. Discussion and conclusion: In the case that the China Hospital information service function is still not perfect, perfecting the functions of China Hospital website plays a decisive role in improving the information service quality of the hospital. In addition, it can be inferred that after the information service function of China Hospital website is improved or the evaluation of the functional quality attribute of website information service scores higher, the supporting attribute of website information service will be the next key task for the hospital in enhancing its information service quality is the improvement ratio of Functional quality attribute of website information service and the supporting attribute of website information service tend to be the same., And even the improvement rate of the supporting attribute is sometimes higher than the improvement rate of Functional quality. So The construction of a model of the comprehensive evaluation system on the information service of has pointed out a new direction in China's research in this field, This model is both of high theoretical value and practical value.


Introduction
According to statistics of China Internet Network Information Center (CNNIC), the number of Chinese netizens, including Internet users on mobile phones, has reached 1.701 billion, which is the largest number in the world, and this number has been increasing year by years [1]. Therefore, the Internet has already been the main approach for the public to acquire information in China. In the meanwhile, medical institutions that provide services for the public are also carrying through the informatization reform. The hospital information platforms thus become the main representative in this reform. Hospitals usually provide more than just medical treatments to patients. They also offer other services including information service. Among them, using hospital information platform is one of the important approaches for a hospital to provide information service to patients. After ten years of informatization, as of 2019, the average rate of third-level hospitals launching information platforms in each province of China has reached 82% [2]. China Hospitals usually provide more than just medical treatments to patients. They also offer other services including information service, consultation service, and psychological service. Among them, using hospital information platform is one of the important approaches for a hospital to provide information service to patients.
In China's mainland, when patients have medical needs and choose hospitals online, they tend to choose a hospital that has high quality information service on the hospital website. They gain information service on the website and proceed with subsequent medical service accordingly. They usually recommend the website providing good experience of online information service to their families or friends in need of medical service. It can be seen that an advanced hospital information platform with high quality information service can not only bring profits to the hospital but also establish the hospital reputation, and more importantly patients can enjoy high quality information service. Therefore, it is of importance to study factors influencing information service quality of hospital information platforms so as to improve their information service quality.
Research on information service quality of hospital information platforms is firstly carried out on information service quality of hospital information system, such as the measurement of effectiveness of the information system and the study on SERVQUAL scale that is used to measure the service quality of information system [3,4]. Then, with the popularity of computers and networks as well as the increase in web browsing, the academic community pays more attention to the research on the service quality of the information system of webpages since 2000. Tan in 2003 studied the service quality frame of the information system [5]. Pinho in 2011 studied the influences of network service quality on network usage [6]. Baldwin in 2014 studied the relationship between the rating of patients' satisfaction and the quality of hospital information platforms and measures [7]. However, China's research on information service quality of hospital information platforms has just started. The major contributions have been made mainly by some scholars in Taiwan and coastal universities in China's mainland. For example, Liang in 2009 conducted a research on the influences of the quality of information platforms on the performance of an organization's relationship with customerss [8]. Pei and Wang in 2009 researched on the evaluation system of information service quality of user-oriented information platforms [9]. Zhu and Xiong in 2012 studied the evaluation criteria on information service quality of medical information platforms [10]. This article shows investigating and studying the information platform of a Hospital Information Platform from the perspective of management, the thesis intends to identify factors influencing the information service quality of hospital information platforms, so as to figure out factors affecting the information service quality of the information platform of a Hospital Information Platform in China and the interaction among these factors.

Methods
This study aimed to understand Factors Influencing Information Service Quality of the Information Platform of China Hospital. To achieve this goal a case study and Delphi and Questionnaire methodology were followed. This study will discuss information service quality of hospital information platforms in two aspects-the essence of the information service of hospital information platforms and perception of information service. Then an evaluation system will be established and verified.
To begin with, following the case study method, this study's object is set within a certain range in order to perform in-depth and comprehensive analysis through dynamic follow-up investigation into them. This study selects the a Hospital Information Platform in China as the object of the case study. Through study design, data collection, data analysis, and study report draft, factors influencing information are sought out as reference for the improvement of service quality of hospital information platforms in China.
Second, Use Delphi and Questionnaire method. In this study Use Delphi, experts in this field are consulted to discuss how to determine or quantify indicators of various dimensions, indicator weights of medical information service quality of information platforms in Chinese hospitals so as to help finish the study [11,12]. In this study Use Questionnaire, In this Questionnaire method, the subjects are given brief forms and asked to offer suggestions or file complaints on certain issues so as to collect information. Based on literature research nd experts' views, a questionnaire is designed for the front-line hospital staff and patients. The questionnaire consists of hospital staff investigation, patient investigation and expert investigation. Every investigation will be carried out two times, and there are two rounds for all the investigations. The first investigation is on the dimension structure of evaluation system for medical information service function and quality of a Hospital Information Platform in China, and the second one is on evaluation system index coefficient of medical information service function and quality of a Hospital Information Platform in China. At last, Statistical Analysis. In this study, Excel is used for data-entry of information in the expert consultation, and SPSS is used for 2 Computational and Mathematical Methods in Medicine statistical analysis of data in the questionnaire so as to examine the consistency and logic of the data and to ensure the correctness of the data.

Comprehensive Evaluation System for Medical Information Service of a Hospital Information Platform in China
3.1. The Structure of System Evaluating the Information Service. This study has randomly chosen 101 experts across China to put into the expert bank of consultation object, ranging from professors in management or other disciplines with deputy senior or above titles to information technology experts at hospitals and professional technicians at information technology web design companies. Next, send the initial dimension indicator set to about 20 experts via mobile phones, letters and emails for at least two rounds of consultation to settle the names, categories, quantity and structure of the evaluation system's dimension indicators. Each round of consultation randomly chooses experts among the 101 consultation objects to send consultation forms, See Figure 1 for details. The expert difference coefficient Q indicates the difference of expert opinion. This variable coefficient demonstrates different degree of expert recognition of the evaluated indicators. The smaller the variable coefficient is, the less the differ-ence of expert opinion is. Calculation equation of variable coefficient: In the equation, Qi refers to the variable coefficient of indicator i, si standard deviation and vi weighted arithmetic mean. In the two rounds of expert consultations, 45 consultation forms were sent out, and 40 valid feedbacks were collected. The effectiveness of the two rounds of consultations was 86%, both of which were higher than 60%.18 dimensional indicators' difference coefficients in the first round are over 0.25, and all these 18 dimensions have been adjusted accordingly; while the difference coefficients of 73 dimensional indicators are all between 0.08-0.24 (less than 0.25). In the second round, only one dimension's difference coefficient is bigger than 0.25, which has been modified, and the difference coefficients of 72 dimensional indicators are all between 0-0.24 (less than 0.25).
In summary, The expert authority degree is 0.846. In the Delphi Method, when the expert authority degree >0.7 it can be seen as relatively high. Hence, the expert authority degree in this round of expert consultation is quite good. Experts have given positive responses to the dimension structure of the indicator system in this thesis quite unanimously, which demonstrates that both the first and second round of

Indicators and Weight Determination. Through the Delphi method, this thesis conducts two rounds of expert consultation and discussion according to the importance of the dimensional indicators of information service evaluation system of a Hospital Information Platform in China. The consultation form is basically the same as the one constructed in the information service evaluation system in the hospital information platform. The difference lies in that the consulting content is changed into the 4 initial weight schemes and the experts can either choose a scheme from the above four schemes or propose their own ones. If the experts do not have a unified opinion after the first round of consultation, the author can merge and sort out the four schemes and the schemes put forward by experts in the first round.
Through the first and second rounds of expert consultation, the final weight distribution scheme is determined. The combined weight values of secondary and tertiary indicators are obtained through multiplication. The combined weight values of the secondary indicators are obtained by Equation (2), while those of tertiary indicators are got by Equation (3).
S wi is the combined weight value of the secondary indicators, S 1i refers to the weight of primary indicator corresponding to indicator i, and S 2i the weight of secondary indicator corresponding to indicator i. See Table 1.
S wi is the combined weight value of the tertiary indicators, S 1i refers to the weight of primary indicator corresponding to indicator i, S 2i the weight of secondary indicator corresponding to indicator i, and S 3i the weight of tertiary indicator corresponding to indicator i. The weighting allocation interval is [0,1], See Table 1. 3.3. Explanation of Evaluation Indicator Assignment. After determining the structure and weight of the comprehensive evaluation system, to improve it and strengthen its  For details about the quantitative assignment of all standards in the comprehensive evaluation system, see Table 2.

Format specification The format specification includes eight sub-items: (well-designed pages, user-friendly font size, uniform page layout, appropriate page margin, pagination on long pages, a horizontal scroll bar on large pages, zoom-in and zoom-out function, all browsers supported.) it has two levels: "Established" valued 1 and "to be established" valued 0. The total score is 7. The calculation of the value of the quantitative standard is: "n" is the number of the sub-items and equals 8.
Wi is the specific value of the i sub-item. The level of the sub-items is figured out through the random examination of 20 pages of the hospital's website.
The "min" function is used to find the smallest value in the given parameter list.

Specification of domain name
The specification of domain name is whether the URL of the hospital website is composed of the hospital's English name or Chinese pinyin initials, whether it has multiple corresponding domain names and whether users find it easy to remember and use. This item has three levels: The digital multimedia function refers to dynamic forms of information services provided by the hospital website, including pictures, sounds, videos, flashes, dynamic pages and 3D interaction programs. Each of the above six sub-items has two levels: "Established" valued 1 and "to be established" valued 0. The total score is 4. In case that advertisement appears in the forms of dialog boxes and float bars on the website, 1 point is deducted. The calculation of the value of the quantitative standard is: and the public and professionals.TThrough the empirical research, we get the comprehensive evaluations of the information service of a Hospital Information Platform's information platform. if participants give different scores for evaluations of these two items, a mean value is adopted as the final score.  Table 3). By means of the Bivariate Correlation in SPSS, the author carried out a correlation analysis of the comprehensive evaluations of the information service of a Hospital Information Platform's information platform and the traffic data of a Hospital Information Platform website, including the total traffic, PV (page view) and UV (unique visitor). The total traffic is equal to PV plus UV. For details of the analysis results, the correlation coefficient among the three objects is 1, a significant correlation. It also suggests that the comprehensive evaluations of the information service of a Hospital Information Platform's information platform and the traffic of a Hospital Information Platform's website are positively correlated. That is to say, the traffic of a Hospital Information Platform's website will vary to the changes in the comprehensive evaluations of the information service of a Hospital Information Platform's information platform.

Conclusions
Based on the actual situation of Chinese hospitals, creates a theoretical research platform of medical information service quality based on the reality of a Hospital Information Platform, and sorts out the core of website information service of Chinese hospitals as well as the influencing factors and their correlations. Focusing on the function and quality of hospital information service, it has established a complete and scientific evaluation system of hospital information service that conforms to the actual situation of Chinese hospitals. Still, through the empirical research on a Hospital Information Platform website, it also validates the scientificity, rationality and practicability of the model proposed in this thesis. The model's scores in various dimensions in empirical researchSee Figure 4 for details.
For the first time in China, the author conducts comparison and correlation analysis of survey results on comprehensive evaluation of hospital website information service and traffic data through empirical research, in order to discuss the relations between the evaluation results and the traffic data. And through the above empirical research to prove the positive correlation between the two, see Figure 5 for details.

Suggestions
The results of the empirical research show Enriching the information service functions plays an important role for hospitals to improve the information service quality of their websites and their website usage. The weight of the functional quality attribute of website information service is 0.7, significantly higher than that of the supporting attribute. In addition, the second-level indicators of the functional quality attribute are the dimensional indicators for measuring the functions of hospital websites, while in the evaluation on January 9, 2020, the evaluation score of the functional quality attribute is 55.41, suggesting a improving.
As the evaluation of the functional quality attribute of website information service shows a large room for improvement, perfecting the information service function of a Hospital Information Platform's website is the key task that the hospital should do to enhance its information service. In addition, that after the information service function of a n" is the number of the sub-items and equals 6. W i is the specific value of the i sub-item. R is the case that incurs any point deduction.
The level of the sub-items is figured out through the random examination of 20 pages of the hospital's website.
The "min" function is used to find the smallest value in the given parameter list.

Website Pageview
The website page view is the function to calculate the number of visitors to the hospital website. According to its function, the item has two levels: "Established" valued 1 and "to be established" valued 0.

Background data
The background data refers to that the information service resources on the website are posted in the format and form of background data. It has four sub-items: 14 Computational and Mathematical Methods in Medicine Hospital Information Platform's website is improved or the evaluation of the functional quality attribute of website information service scores higher, the supporting attribute of website information service will be the next key task for the hospital in enhancing its information service quality.
From the data in Figure 6 and Table 3, we can see that the improvement ratio of Functional quality attribute of website information service and the supporting attribute of website information service between 2017/8/18 and 2020/1/9 tend to be the same. And even the improvement rate of the   supporting attribute is sometimes higher than the improvement rate of Functional quality. All in all, between 2017/8/18 and 2020/1/9, the final score of the functional quality attribute of the website information service in 2020/1/9 is about 6 times that of 2017/8/18, and the support attribute of the website information service The final score in 2020/1/9 is about 3 times that of 2017/8/18,see Figure 6 and Table 4 for details.
This study is the first one in China that applies both the Delphi method and composite grade method to construct the model of comprehensive evaluation system of hospital information service. For the first time in China, the author conducts comparison and correlation analysis of survey results on comprehensive evaluation of hospital website information service and traffic data through empirical research, in order to discuss the relations between the evaluation results and the traffic data. Therefore, it bears considerable reference value. This model is both of high theoretical value and practical value. But the development of new network information technology often goes beyond hospital managers imagination. Therefore, the information service evaluation system in this thesis will be enriched with the development of the times and information technology.
