Get an Original EssayINTRODUCTION The Internet of Things is the network of physical devices, vehicles, appliances, and other objects embedded with electronic components, software, sensors, actuators, and connectivity that allow these things to connect and exchange data. The Internet of Things is a general concept for the ability of network devices to connect to each other and collect data from the world around us. The collected data can be shared on the Internet and used for various purposes. Healthcare is an essential part in our daily lives. Unfortunately, the growing aging of the population and the consequent increase in chronic diseases are putting strong pressure on our healthcare system. Demands for hospital beds on doctors and nurses are increasing. Therefore, a solution is needed to reduce the pressure on the healthcare system. The main purpose of the Internet of technology in healthcare is to connect doctors with patients through smart devices, without any restrictions. The patient may open up better, helping the doctor diagnose faster. This leads to consumer empowerment, doctors can make informed decisions through improved connectivity, precision-centered monitoring and information gathering. IoT in healthcare serves two main purposes. Improve disease management by providing a better patient experience and reducing healthcare costs. METHODOLOGY Healthcare Architecture in IoT A body sensor network is a network specially designed to work independently to connect various medical devices to be connected and monitored. The body sensor network consists of various sensors and medical implants that can be placed inside or outside the human body. An integral layer of IoT is to introduce connected smart devices that can monitor patient health, collect data, and alert medical staff with any indication of impending illness or worsening condition. Patients can wear these devices because medical personnel can monitor patients' health. This network of body sensors can be useful in monitoring at-risk patients and making precise decisions that can help avoid frequent trips to the emergency room. Multi-service gateways are used to manage the application remotely and to provide wireless connectivity. This helps in processing, transferof data and data aggregation for machine-to-machine solution. Applications have been created for both patients and hospitals to collect and analyze data. Multi-service gateways are a great help in keeping track of patient conditions. Routers are used to collect data which is then uploaded to the dedicated data collection storage. Machine to Machine integration is currently one of the fastest growing connected device technologies. It can use sensors to communicate, meaning the system can monitor itself as it responds to its surroundings. This technology requires much less human intervention. It can collect patient-specific data, transfer and analyze it directly there and you can provide a decision more quickly. For example, if a patient's vital sign declines, a cloud-connected device or sensor can administer oxygen and provide additional care until medical personnel arrive. With the help of this technology the patient can receive treatment when he is at his home. Machine to machine is the perfect technology when communication with the patient is necessary. C. Report generation, reminders/alerts With the machine-to-machine integration platform, data collected and stored in the cloud can be used to analyze and verify models. If a patient has a doctor's appointment on a certain day, the device will remind the patient, send notifications and reminders. The wearable device also reminds the patient to take medicines via reminders/alerts. DISCUSSION Security The security of personal health information stored and transmitted by connected devices is a major concern during smart healthcare system implementation. Attacks or breaches mainly focus on three objectives. Web interfaces possess several serious vulnerabilities. There are several tools available on the web that attackers can use to find security gaps in web servers. IoT devices and databases are vulnerable to security breaches. The attacker could delete all information from the database and replace it with false information. Wireless technologies are more susceptible to data tampering. This can be avoided by setting up user profiles with limited access and permissions. Multi-factor authentication and data encryption can prevent data breaches. Perform regular checks on connected devices. Integrating Multiple Devices The most important challenge is setting protocols and standards for integrating multiple devices. Since several mobile devices are connected to the network for data collection. Since the implementation of different protocols is different, this results in a complication for data collection. Deriving results from data The process of aggregating and collecting data is very complex. Coming to a conclusion from such a large amount of data is a very challenging task, without refined analysis programs and data experts. Identifying the correct and valuable data is the most challenging part which most of the experts and doctors find most difficult. Decision making is influenced by the growing amount of data. The concerns are becoming bigger and bigger as there are many devices that collect data continuously. BENEFITS Improved Patient Engagement Patient engagement plays an important role in implementing a value-based care program. With IoT, patients track their health data. This way the patient is aware of the progress he has made so far. Doctors and medical experts have access to real-time patient data.There are many applications available in the market that can be integrated with fitness tracking devices such as Apple Watch, Fitbit etc. These applications can collect real-time data and send it to medical staff for evaluation to improve healthcare services for patients. Reduced healthcare costs availability of real-time data via wearable devices has allowed medical staff to monitor patients' health remotely. Doctors and patients don't need physical meetings. Text reminders/push notifications based on patients' health. Application that helps patients follow instructions to take care of themselves. Alerts to medical staff about critical patient conditions and upcoming appointments. Such smart healthcare facilities and applications help detect complications at an early stage, which leads to significant costs through reduced hospital readmissions. Better chronic care management One of the most important aspects of chronic diseases is ongoing health monitoring and evaluation of the patient's health. Doctors are more confident in remote monitoring of patients and can monitor health parameters more accurately. Drug Management IoT is a miracle in drug management too. We have smart healthcare facilities to track medications and fill them automatically when needed. This intelligent technology collects the date in real time and sends it to the application. The app tracks the missed dose and, if there is one, sends reminders to patients in the form of text messages, phone calls or lights on the bottle. This system is of great help in the treatment of chronic diseases. Reduce Errors IoT enables accurate data collection, workflow automation, and reduces errors. Reduces waste by minimizing unnecessary testing and costly imaging required. Smart Health provides connected home care that helps reduce hospital stays and readmissions. Machine to Machine architecture allows you to monitor your patient in the comfort of your own home. Numerous sensors are installed in the device held next to the patient. The data collected by the devices is then monitored by qualified hospital staff. Thus reducing the possibility of error and improving the quality of the service offered by the hospital. Advanced IoT patient management provides proactive and timely services. It places emphasis on the needs of patients. It provides greater accuracy and precision in terms of diagnosis. Timely intervention by qualified medical personnel results in better treatment. Thus improving patients' experience with the hospital. Improved Treatment Outcomes Healthcare solutions make use of cloud or virtual infrastructures that give medical staff the ability to access data in real time. This allows them to make informed decisions and provide better care. SMART HEALTHCARE APPLICATIONS IoT applications deserve deeper consideration. You may notice that the services are used to create applications, although the applications are used specifically by customers and patients. Despite the hidden applications in this area, we talk about several devices, wearables and other medical devices currently available on the market. These elements can be seen as IoT advancements that can lead to different healthcare solutions.
