## Abstract

In order to standardize the health management of pregnant women, improve the health level of pregnant women, and improve the outcome of pregnancy with the help of the smartphone mobile terminal app, the 100 pregnant women who gave birth in the hospital and participated in the management of the health assistant app were selected as the observation group, and the 100 hospitalized pregnant women who did not participate in the management of the app were selected as the control group. The two groups of pregnant women were compared in their knowledge of health care, compliance of prenatal examination, delivery mode, and follow-up rate. The results showed that the observation group was significantly higher than the control group in the knowledge of health care during pregnancy and perinatal period, the rate of natural childbirth, the compliance rate of prenatal examination, and the follow-up rate. After the system was launched, the number of registered pregnant women reached more than 60% of the total number of pregnant women in the hospital, the number of clicks reached more than 2 million times, the number of clinic settlement accounted for more than 30%, and the interpretation rate of fetal heart rate in outpatient and remote clinics reached more than 20%. The diagnosis and treatment process has been significantly improved, and the implementation effect has reached the expectation. O2O maternal and child service mode has been realized through mobile internet technology. It has been proved that the use of smart mobile terminals in the out-of-hospital health care management of pregnant women not only facilitates medical staff to provide timely personalized medical services for pregnant women but also is convenient for pregnant women to obtain health care knowledge through multiple channels, improve the quality of home health management for pregnant women, and effectively improve the pregnancy outcome.

## 1. Introduction

With the development of economy and technology, people’s requirements for their own health are gradually improving, and medical care and preventive medicine have been widely concerned; research conducted by the World Health Organization shows that effective preventive care and timely information communication play an important role in keeping people healthy [1]. However, the disadvantages of high cost and low efficiency of the traditional medical model become increasingly prominent, such as “difficult to see a doctor,” “three long and one short,” and other medical problems which have become the obstacles of people’s health care. In this regard, China’s medical and health system attaches great importance to the transformation of the medical model and puts forward the solution of medical informatization, strengthens the information construction of the medical and health system, and makes the majority of residents get complete health information records, convenient medical procedures, and high-quality medical and health services with the help of computer technology. Smartphones are the most common “personal computers” today, they have completely changed the communication environment, the rapid development of hardware makes them with rich display content and easy to operate the screen, more powerful computing power of the CPU, larger capacity of memory, and faster data transmission service network communication capabilities, these advantages make smart phones considered to be very promising health care tools, and the mobile health care model organically combined with smart terminal devices and mobile internet has become a new health service mode gradually recognized by people [2]. As one of the most important components of the public health service system, maternal and child health care institutions mainly serve young parents, which is very suitable for smartphone users; therefore, it is also a trend to gradually develop mobile maternal and child health care services [3]. The importance of pregnancy is self-evident for pregnant women, who are particularly eager to learn more about their health and to receive more guidance on maternal and child health care; this includes recording physical signs to monitor their health status in real time, inquiring about maternal and child health knowledge as needed, and convenient remote medical consultation and diagnosis. Meanwhile, the biggest advantages of smartphones are real-time communication, high portability, and rich software features; it is of practical importance to design and build an mHealth system that can improve maternal health care services based on these features [4].With the implementation of the universal two-child policy, the number of pregnant women has increased significantly in recent years, popularizing scientific knowledge, improving the quality of maternal health management, and reducing the burden of hospital outpatient service which are the urgent problems to be solved in the health care work of maternal groups in China [5]. As an emerging means of socialized medicine, mobile medical platform has been gradually and widely applied in the medical service model [6]. Among them, mobile medical app has been accepted by the masses because of its simple and easy operation, the self-health management of pregnant women can effectively prevent pregnancy complications and fetal health and safety problems, and good health care during pregnancy and childbirth can improve the health of the mother and child. This study reviewed the application of maternal health management app in order to provide reference for similar studies in the future [7]. Therefore, the development of information technology has promoted the reform of human resource management. The application of intelligent attendance technology has changed the traditional way of attendance, improved the efficiency of human resource management, and provided better service for the organizational strategy. Wu et al. discussed new attendance methods, including face recognition, fingerprint recognition, iris recognition, and other nonmobile attendance, and enterprise WeChat, tripod attendance, and other mobile attendance, and the application of five different intelligent attendance technologies is compared and analyzed. It is proposed to improve mobile attendance app, deepen electronic human resource management, mine big data of human resource management, and realize the deep integration of intelligent attendance technology and human resource management in further research [1]. Andreev et al. designed an intelligent drug management platform based on deep learning. Based on the intelligent medicine box, combined with mobile app, WeChat official account, mini program, etc., the platform can not only realize the functions of timing, intelligent reminder, medication record feedback, etc, but also provide medication information and multiservice supervision for patients, which can significantly improve patients’ irregular medication and reduce drug leakage [8]. Xu et al. studied the particular difficulty of emergency care due to the transient and dynamic individual patient environment; all methods currently implemented are designed regardless of physical states and different manifestations of cognitive impairment. Therefore, our goal is to design and integrate a telemedicine platform, which is an intelligent user interface solution that can be adapted to clinical emergency patient situations in real time. The present study proposes a mobile implementation of hypoglycemic therapy for diabetes. Continuous physiological data from medical-grade wearable sensors, as well as customized cognitive training results evaluating corresponding common emergency symptoms, are used to define patient status [9]. On the basis of current research, it is proposed to standardize the health management of pregnant women with the help of smartphone mobile terminal app, improve the health level of pregnant women, and improve the outcome of pregnancy. It has been proved that the use of smart mobile terminals in the out-of-hospital health care management of pregnant women not only facilitates medical staff to provide timely personalized medical services for pregnant women but also is convenient for pregnant women to obtain health care knowledge through multiple channels, improve the quality of home health management of pregnant women, and effectively improve the pregnancy outcome [10].Mobile medical system constructed by mobile Internet can effectively remind patients with gestational diabetes and transmit data automatically. For mothers and nurses, communication has brought the convenience, but this approach in patients with gestational diabetes blood sugar control and neonatal birth weight on both primary endpoint events did not see a significant difference. Due to the increase of the diabetes population, the number of specialized health care teams for diabetes-related pregnancy is relatively reduced. However, the mHealth system can effectively reduce the number of patient visits and play a positive role in the rational allocation of health system resources. Both patients and the health care system can benefit from this. Although the results of the two studies are different, the positive effects of mHealth in this particular group of diabetics are worth looking forward to.


## 2. Research Objects and Methods

## 4. Discussion

### 4.1. Complete Interconnection of Pregnancy Health Information

At present, most maternity management systems only connect to midwifery units and have no connection to maternity records or HIS. These systems are very limited and not interconnected. Through the development of the health assistant app, three interconnections have been realized: one is the seamless connection with personal electronic health records, with ID number as the unique identification number; an ID card has only one electronic file in the hospital system to avoid the error of manual statistics. The second is to realize the interconnection of pregnancy information and antenatal information; through the combination of patient ID and diagnosis, the data of pregnant women can be automatically entered into the files of pregnant women, ensuring the convenient management of the whole file of pregnancy and childbirth [18]. The third is the establishment of child health information management; through the mother ID, the child's birth information and postpartum follow-up information are automatically imported, so as to realize a set of continuous and complete health files during pregnancy, perinatal period, and neonatal period, and make the pregnancy and childbirth management more scientific, standardized, effective, and feasible. Maternal and child health hospitals mainly cater to women and children, with particular emphasis on pregnancy services. Pregnant women are particularly problematic during pregnancy. In order to meet the needs of pregnant women in terms of health, medical treatment, and health care, pregnant women can consult obstetricians through the app. Through the personal signs uploaded by pregnant women, doctors can learn about the physical signs of pregnant women remotely; at the same time, they can access the personal pregnancy health record system to check the personal birth examination records of pregnant women and put forward targeted guidance and suggestions. Pregnant women do not have to personally run to the hospital; regular problems can be solved by online counseling.The system automatically collects, stores, and uses statistical information, associating new information with past information and showing the current health status of pregnant women in a timely and comprehensive manner. The complete storage of health records of pregnant women and women can be realized to provide accurate and fast data for medical staff, so as to facilitate medical staff to carry out personalized health education work. Through the system design, the function of appointment inspection, and automatic reminder of follow-up expiration, it is convenient for medical staff to carry out health guidance and remind pregnant women to carry out pregnancy examination in time, thus improving the quality of maternal health management. The app is simple and convenient to use. You can access the internet through your mobile phone and log in directly, which solves the problem of discontinuous information under the traditional health care mode. At the same time, the health assistant app is deployed on two servers to ensure the security and stability of the system through comprehensive use of data encryption technology and management methods.


### 4.2. Platform Functions Are Easily Accepted by Doctors and Patients

As can be seen from Figure2, the utilization rate of high school and college degrees is relatively higher than that of junior college and junior high school. Health assistant app can intelligently remind medical staff to promote maternal health behaviors in multiple forms and multidimensions; it not only facilitates medical treatment but also improves the compliance rate of prenatal examination and health knowledge of pregnant women. In addition, through the expansion of WeChat public platform functions, one is to achieve advance appointment and shorten the time to see a doctor; second, push health education materials in the form of pictures and videos on a regular basis to make the education more intuitive and easy to understand. At the same time, pregnant women should obtain appropriate health information according to their own needs, so as to achieve a targeted goal and avoid one-time indoctrination which becomes a formality. The results of this study indicate that the timely follow-up of antenatal clinic can not only improve the regular antenatal examination and timely detection of birth defects but also increase the maternal compliance with pregnancy health care. Health assistant app provides a convenient, personalized, fast, effective, and spatial-temporal service mode for continuous service, which is worthy of clinical application and promotion. Mobile internet technology can enhance traditional forms of television, radio, and live education. Through live broadcasting and retrospecting, the curriculum of the maternity school can be put online. Pregnant women can inquire about health knowledge and watch health education courses anytime and anywhere with just a few taps on their mobile phones, forming an effective supplement to traditional health education methods.Figure 2
Usage comparison.


### 4.3. Shortcomings

The emergence of mobile health apps brings challenges as well as opportunities for the development of maternal health. With the increasing use of apps for pregnant women, people are paying much attention to the quality of their content, the authenticity of online resources, and the security of personal information. The extensive use of mobile health involves a large number of health data, the leakage will bring serious adverse impact on the development of the mobile health industry, personal information security, and other issues, but China’s mobile health app field supervision and legal norms are almost blank. At present, the mobile medical app for pregnancy health care has the following problems: low threshold, market chaos, lack of professionalism in the information content, lack of standard diagnosis and treatment procedures and use guidelines for mHealth, relative lack of technical personnel, etc. Therefore, China needs to formulate laws and regulations related to the mobile medical app as soon as possible to make the mobile medical market more standardized; at the same time, we are constantly optimizing the app, improve user experience, and better play its social benefits for maternal health and life to bring better experience.

## 5. Conclusions

In order to standardize the health management of pregnant women, improve the health level of pregnant women, and improve the outcome of pregnancy with the help of the smartphone mobile terminal app, the 100 pregnant women who gave birth in the hospital and participated in the management of the health assistant app were selected as the observation group, and the 100 hospitalized pregnant women who did not participate in the management of the app were selected as the control group. The two groups of pregnant women were compared in their knowledge of health care, compliance of prenatal examination, delivery mode, and follow-up rate. The results showed that the observation group was significantly higher than the control group in the knowledge of health care during pregnancy and perinatal period, the rate of natural childbirth, the compliance rate of prenatal examination, and the follow-up rate. It has been proved that the use of smart mobile terminals in the out-of-hospital health care management of pregnant women not only facilitates medical staff to provide timely personalized medical services for pregnant women but also is convenient for pregnant women to obtain health care knowledge through multiple channels, improve the quality of home health management for pregnant women, and effectively improve the pregnancy outcome.
