## Abstract

The purpose of this paper is to study the feasibility and economic benefits of intelligent medical Internet of Things (IOT) systems for improving the quality of life of hemophilia patients, thereby reducing the risk of teratogenicity and disability for patients. This article selects 60 severe hemophilia patients who were followed up in our hospital from 2018 to 2019 as the research object. In the intelligent medical system, the Gaussian mixture model discretization algorithm is used to preprocess patient data collection. The observation group uses the intelligent medical system to implement home nursing for the patients, and the control group uses ordinary home nursing. This paper evaluates the quality of life of the two groups of patients 6 months after the intervention, including self-care ability, transfer function, and home nursing cognitive ability. The research results show that the home nursing based on smart medical IOT proposed in this paper is feasible and effective for improving the quality of life of patients. It can effectively improve the patient’s self-care ability and joint functions and has important reference value for the development of intelligent medical IOT equipment.

## Body

## 1. Introduction

The concept of hemophilia care originated in the United Kingdom in the late 1940s. The first Hemophilia Treatment Centre (HTC) network formed by a comprehensive team was established in the United States in 1976. At present, a large number of practices and studies have shown that this comprehensive care of hemophilia, in which a group of multispecialized medical staff provide comprehensive treatment, care, and life guidance to hemophilia patients and their families, is the most ideal model for the treatment of hemophilia and other bleeding disorders. Moreover, this treatment model has gradually been adopted by many economic and medical developed countries around the world. Among them, nursing as the main role is the key to the implementation of this economical and effective model. Hemophilia care not only plays a major assisting role in the multidisciplinary medical treatment of hemophilia but also plays a leading role in the comprehensive care of hemophilia such as publicity and consultation, family treatment, and follow-up management. As a genetic disease that requires life-long treatment, hemophilia care is the primary task of changing the status quo of hemophilia patients in developing countries. Therefore, it is very important for hemophilia patients to take good care of hemophilia and reduce bleeding and complications. The pros and cons of the hemophilia care model that runs through the diagnosis and treatment of hemophilia are also considered to be an important guarantee for determining the prognosis and quality of life of patients.The World Health Organization (WHO) defines a rare disease as a disease or disease in which the number of patients is between 0.65‰ and 1‰ of the total population. Currently, WHO has confirmed more than 5,000 rare diseases, accounting for about 1/10 of human diseases. Rare diseases have the characteristics of low incidence, strong harm, low curability, and low social understanding. Moreover, many countries and regions in the world are very concerned about the survival and development of rare disease groups and have issued relevant laws and regulations to protect the realization of the rights and interests of rare disease groups. From the perspective of health economics, if patients with rare diseases can receive effective treatment early, the medical loss caused by disability due to illness can be avoided, and more social costs can be saved. Treating patients with rare diseases equally is not only an important symbol of a harmonious society but also has important social significance and academic value. “People-oriented” is the core of China’s socialist scientific development concept, and paying attention to the warmth of a few people is a concrete manifestation of the “people-oriented” concept. In the 1980s, China began to pay attention to rare disease research, and in 1985, it publicly proposed rare diseases in China. However, up to now, China does not have an official definition of rare diseases, statistical data on disease types, and related laws and regulations, and there is no medical model suitable for rare diseases. The research on rare diseases has become a weak link in the field of research in China, and the research on rare diseases urgently needs the attention of the whole society. Hemophilia has a long history of research. Because of its “special status” as a “royal disease,” the development of hemophilia has attracted the attention of scientists, governments, organizations, and the public internationally and has always been ahead of other rare genetic diseases. In addition, as a relatively mature rare disease, the systematic study of hemophilia can provide a reference for the research of other rare diseases in China. In summary, hemophilia seriously affects the health and quality of life of patients, and it is a chronic disease with a disabling and fatal rate in China. However, in developed countries, due to the early diagnosis of hemophilia and the widespread use of preventive treatments, childhood bone and joint disease and life-threatening bleeding have been avoided, the joints of patients remain intact, and the mortality rate is significantly reduced. The comprehensive care model for hemophilia improves the long-term prognosis of patients. The quality of life and life expectancy are close to those of the normal population. The quality of life of child patients is even higher than that of normal children of the same age due to social concerns. With the improvement of plasma screening and blood product processing technology and the application of recombinant factor products, the transmission of HIV, HBV, and HCV through coagulation factor concentrates has been almost completely eliminated in developed countries. This shows that the level of prevention and treatment of hemophilia in China is far from that of developed countries. Doing a good job in the prevention and treatment of hemophilia in China can not only reduce the disability and death rate of patients and enable patients to enjoy the right to live, study, and work like normal people but also reduce the economic burden of patients’ families and the country, which is of great significance for ensuring social stability and building a harmonious society.This article combines the intelligent medical Internet technology to study the impact of home nursing on the quality of life of hemophilia patients and evaluates the effect of home nursing for hemophilia, which provides a theoretical reference for the subsequent improvement of the care effect of hemophilia.


## 2. Related Work

Hemophilia care develops along with the development of hemophilia. Early literature searches showed a small number of individual case care for hemophilia patients, but only for the care of disease symptoms. The advent of concentrated coagulation factor preparations has brought effective treatment to hemophiliacs and made possible large-scale home treatment and preventive treatment [1]. As complications related to hemophilia treatment arise, hemophilia care has also expanded to include comorbidity care. However, as a rare disease, medical institutions rarely recognize and pay attention to hemophilia. The treatment and education of hemophilia patients urgently need the support of professional medical personnel [2]. The UK was the first to create a professional hemophilia clinic (HTC), which is also the origin of a professional hemophilia care centre. It is not positioned as “nursing” in a narrow sense but focuses more on the overall care of patients. The work of the initial 18 centres focused on professionally diagnosing patients with hemophilia, issuing hemophilia identification cards, providing psychological support, and protecting them from hospital treatment [3]. In the process of hemophilia diagnosis and treatment, people gradually realize that if hemophilia prevention, nursing knowledge education and measures are in place, and patients receive safe and effective treatment at an early stage, bleeding can be minimized or avoided, thereby improving quality of life of patients [4]. Therefore, appropriate hemophilia care is critical to improving patient outcomes. Since then, HTC has facilitated outpatient visits for hemophiliacs, trained medical staff and patients in other hospitals on the disease, educated patients on intravenous coagulation factors, served as a liaison with social welfare services and with other HTCs, and collaborates on scientific research [5]. The ever-increasing number of HTCs has expanded expertise that was previously only available to a few medical specialties to many more. These shifts have also expanded the impact of HTC on hemophilia patients in remote areas and enhanced regional hemophilia specialty care [6]. The multidisciplinary cooperative diagnosis and treatment pioneered by HTC laid the foundation for lifelong diagnosis and treatment and also clarified the connotation and extension of comprehensive hemophilia care [7]. Hemophilia care is no longer limited to one discipline, one area. Instead, it is based on the attention of the entire hemophilia diagnosis and treatment team to hemophilia patients and the close cooperation between experts and patients/families to build a core group. Core team members include hematologists, paramedics, social workers, physical therapists, blood banks, and personnel from diagnostic laboratories. Other members, either on the core group or as consultants, include specialists in imaging, genetics, orthopaedics, obstetrics and gynecology, hepatology, and infectious diseases [8]. In economically and medically developed countries, the diagnosis and treatment of hemophilia has developed from a simple model to this advanced comprehensive care model, and nurses who play the main role are the key to implementing this cost-effective model. Hemophilia nurses not only play the role of the main facilitator in the multidisciplinary medical treatment of hemophilia but also play a leading role in comprehensive care such as education consultation, family therapy, and follow-up management [9]. As a link between patients and families and between patients and other members of the comprehensive prevention and treatment team, nurses can provide appropriate and effective treatment according to the type and degree of bleeding of patients; they go deep into patients’ homes to help patients and families deal with the risks and problems of daily life, risks and issues, particularly with regard to bleeding management; regular follow-up of hemophilia patients registered in the clinic and assistance with rehabilitation [10]; provide publicity and education to knowledgeable patients, family members, medical staff, etc.; and participate in domestic nursing organizations to seek more support, care, and participation. For complex cases, nursing staff will appropriately consult hematologists or other team members to complete nursing tasks [11]. It can be seen that the most important part of comprehensive care for hemophilia is to popularize and improve nursing work.Although most people with hemophilia have basic knowledge of home preventive treatment and care, they still need to know more about it [12]. Studies have shown that many people with hemophilia want to be informed about the latest research findings and to have the opportunity to participate in relevant trials [13]. Hemophilia patients still need to continuously improve their self-management skills on the basis of understanding the relevant family treatment and nursing knowledge. Studies have shown that children need to gradually improve their self-management skills from their mothers. The average age of children with self-management skills is 14.1 years old [14], but there are still some problems in self-management. A survey showed that 32% of 307 patients with hemophilia developed anxiety and/or depression due to a lack of self-management skills, such as they considered having a bleed as a stigma, and almost half of the patients were very cautious to tell others that they have had bleeding. Therefore, they urgently need to continuously improve their self-management ability [15].


## 3. Research Methods

The daily care of hemophilia patients has become an urgent problem to be solved, and smart medical treatment and smart diagnosis and treatment are considered to be one of the most promising. For this reason, this paper designs a hemophilia patient monitoring system based on the PPG signal of a smart phone, as shown in Figure1. The terminal mobile phone user uses the mobile phone to record the video, and then the video is uploaded to the server. The algorithms for signal extraction and processing in Section 3 are all efficiently performed on the server.Figure 1
Home care monitoring system for hemophilia.The design of the client takes into account the huge Android user group that occupies more than 80% of the market share. The openness of its platform allows any mobile device manufacturer to join the Android family, which means that Android phones of any brand have the opportunity to use the client of the hemophilia patient monitoring system designed in this paper. Using this CS architecture can make the client and server have good interactivity, secure access mode, and low network traffic and facilitate the transmission of large amounts of data such as video. At the same time, because it takes advantage of the resources on the server side and has superior processing capabilities, the client’s response speed is extremely fast, as shown in Figure2.Figure 2
The design and data flow of the physiological parameter monitoring system for hemophilia patients.The layered model of intelligent unit software is divided into perception layer, network layer, data processing layer, and service layer. The model is shown in Figure3.Figure 3
Layered model of intelligent unit software.The perception layer includes the sensing devices in the smart unit, and the physical devices in the smart device are divided into two parts: agent devices and unique devices. The unique device is mainly a sensor device, and the unique device is the source of the basic data information of the intelligent unit. Data collection technology has become mature and has a wide variety, including radio frequency identification, infrared beacon, and two-dimensional code. Sensors or other sensing devices sense a large amount of real-time environmental information, collect data, and transmit wireless or wired data. Communication technology transmits short distances to central nodes or network equipment. The area covered by the sensor network can basically not be restricted by the region, and it can be set up quickly (tens of minutes), which has great advantages in terms of erection time, convenience, and reliability. The intelligent unit has different unique devices according to its own functions. This article takes the home nursing smart unit for hemophilia as an example. Among them, environmental monitoring equipment includes air conditioners, humidifiers, cameras, etc., physical sign monitoring equipment includes smart watches, pulse oximeters, etc., and treatment equipment includes noninvasive ventilators, household oxygen generators, and smoking cessation devices. Moreover, environmental monitoring equipment usually embeds ZigBee modules to form a ZigBee network. The physical sign monitoring equipment is usually embedded with a Bluetooth module to form a Bluetooth network. The treatment equipment is usually embedded with a Wi-Fi module to form a Wi-Fi network. Therefore, the underlying network is divided into three types of heterogeneous networks: environmental network, body area network, and therapeutic network.The bottom network networking is realized by the receiving module in the intelligent gateway. Since the underlying networks in the home care unit for hemophilia are three heterogeneous networks, the environment network, the body area network, and the treatment network, the following three sensors used in the home care system for hemophilia patients are introduced, respectively.


### 3.1. Networking Process

#### 3.1.1. ZigBee Networking

The uniqueness of a ZigBee network is determined by PANID (Personal Area Network ID) and Channel. The ZigBee networking process is as follows: (1) network by opening the ZigBee receiving module in the intelligent gateway; (2) select the appropriate channel according to the network environment; (3) configure the PANID and other parameters, and the network is completed; and (4) wait for the environmental monitoring equipment to access the network. If the environmental monitoring device is allowed to access the network, the receiving module responds to the request of the environmental monitoring device and assigns an address to it, and finally, the address can be used for data transmission.


#### 3.1.2. The BT Wireless Module

The BT wireless module of the Bluetooth network has two different working modes: ① command response mode; ② automatic connection mode. If you choose the second method, the BT wireless module will automatically connect according to the preset method. The module can be divided into master working mode, slave mode, and loopback mode. The master device will actively query the surrounding Bluetooth slave devices and start the connection. Both the slave device and the loopback device are waiting to be connected. In the case of the home care system for hemophiliacs discussed in this paper, the vital monitoring device in the body area network acts as a slave mode node, while the intelligent gateway acting as a connecting device in an intelligent unit acts as a master mode node. The Bluetooth networking process is as follows: (1) the Bluetooth gateway receiving module is initialized after power-on; (2) searches for Bluetooth devices; and (3) when the correct personal identification code (PIN) is entered, assign a unique network address.


#### 3.1.3. Wi-Fi Networking

Wi-Fi wireless sensor, like Bluetooth, also has two working modes: ① AP (access point) working mode; ② Sta (station) working mode. Nodes working in the first way are network builders and at the same time network hubs. If the treatment device in the home care system for hemophilia patients enables the second working mode, and the smart gateway enables the first working mode, the networking process is as follows: (1) after the Wi-Fi gateway receiver module is turned on, configure Wi-Fi hotspot; (2) set the SSID (Service Set Identifier) of the Wi-Fi network, and broadcast the SSID every 100 ms through the beacon; and (3) wait for the treatment device to access the network. When a therapy device joins, it is assigned a unique network address.The network layer mainly implements the following two functions: ① perceive network connection, which is the bottom layer network, and ② heterogeneous network conversion, which is the conversion between the bottom layer network and the upper layer network. At the same time, it has to solve the problem of data conversion between the underlying sensor networks; the functions of the network layer mainly rely on smart gateways.The gateway receiving module can not only realize the underlying network networking but also connects to the main module in the smart gateway by a serial port. The main module is the core to realize the conversion of heterogeneous networks. It is mainly responsible for data packet processing, data fusion processing, external network access, and data forwarding from the gateway receiving module. The network layer of the home nursing system for hemophilia patients is shown in Figure4.Figure 4
Schematic diagram of system network layer.


### 3.2. Method

This article selects 60 patients with severe hemophilia who were followed up in our hospital from 2018 to 2019 as the research object. They are randomly divided into a control group (n=30) and an observation group (n=30), and all patients were male. The average age is 53.21±4.28 years old, and the range is 38-69 years old. The care plan is developed and implemented by rehabilitation therapists, nurses, and patients’ families in the hemophilia centre. In the intelligent medical system, the discretization algorithm of Gaussian mixture model is used to preprocess patient data collection.The control group takes routine community care, that is, through communication with community health personnel, a lecture on hemophilia knowledge is held once a month, and the knowledge of preventing complications of hemophilia is passed on to community personnel. At the same time, it is necessary to publicize hemophilia knowledge in the publicity column and cooperate with the distribution of hemophilia publicity materials, so that the community can learn and understand the basic knowledge, complications, and prevention methods of hemophilia through self-study. On the basis of the control group, the observation group added home nursing intervention programs, including: ① It is necessary to distribute the “Hemophilia Family Treatment Manual” and “Hemophilia Patient Bleeding Record Book” to every hemophilia family and conduct family care education and bleeding records based on this. The content of this family manual is accurate, practical, and highly maneuverable. It is recommended by the World Federation of Hemophilia and provided free of charge. ② Strengthen screening to avoid birth defects: Hemophilia is a lifelong disease that is carried by women and causes the next generation of men to develop. This lifelong disease has a long course and high cost, which brings certain financial pressure to the family. Currently, there is no cure for hemophilia, and the most effective treatment is alternative treatment. That is, home treatment and care are used to achieve rapid hemostasis, reduce hospitalization, and ensure that patients study and live normally. Through active genetic counseling, strict premarital examinations, prenatal diagnosis after pregnancy, and prenatal and postnatal care, the number of births of children with hemophilia can be reduced, and the quality of birth and family life of the Chinese population can be improved. At the same time, rehabilitation therapists set short-term, medium-term, and long-term goals for the patient based on the actual situation of the patient. It is necessary to stipulate that the content must be completed every day, but it is not mandatory to complete it. In addition, patients upload rehabilitation training videos daily, doctors and patients communicate via WeChat video, and rehabilitation therapists give feedback, evaluation, and guidance on their completion. However, it should be emphasized that training content and training intensity cannot be changed without authorization. If patients feel unwell, they need to contact the clinic immediately.The FISH scale for hemophilia functional independence score is a specific scale for assessing the ability of daily activities of hemophilia patients. The evaluation content includes 3 aspects, namely, self-care function (eating and washing, bathing, and dressing), transfer function (wheelchair transfer and squatting), and migration function (walking mode, up and down stairs, and running), and the total score is 32 points. The score is divided into 4 levels according to whether the patient has discomfort or the degree of assistance needed in the process of completing the task. The higher the score, the better the daily activity ability of the patient. In addition, the FISH scale has good internal consistency, has a moderate correlation with the World Hemophilia Clinical Score and Pettersson Score, and has a good correlation with other self-function measurement scales. The researcher demonstrates the items listed in the FISH scale to patients and evaluates their completion.

## 5. Analysis and Discussion

The quality of life score of the observation group and the quality of life score of the control group at follow-up were very close, and there was no statistical difference. At 6 months, the quality of life score of the observation group was significantly higher than that of the control group. Moreover, the self-care ability and transfer function and home nursing cognition ability of the observation group were significantly higher than those of the control group (P<0.05). Comparing the nursing cognitive ability of the two groups of families, it was found that before the intervention, the family nursing cognitive ability score of the observation group was close to the family cognitive score of the control group. After the intervention, the nursing cognitive ability score of the observation group is significantly higher than that of the control group. The functional independence scores of the two groups of hemophilia patients are evaluated in the first, third, and sixth months of home nursing by follow-up. At the same time, it is necessary to evaluate the FISH score for 1 month of nursing, the FISH score for 3 months of nursing, and the FISH score for 6 months of nursing. The results show that the scores of self-care ability and transfer function of the observation group are significantly higher than those of the control group (P<0.05). In summary, the home nursing based on smart medical IOT proposed in this study is feasible and effective for improving the quality of life of patients and can effectively improve the patient’s self-care ability and joint functions, which has important reference value for the development of smart medical IOT equipment.
