Amrita Mobile Health Solution - A mobile healthcare solution for rural India
1
ABSTRACT People in rural areas face some different health issues than people who live in towns and cities. Getting health care can be a problem when you live in a remote area. You might not be able to get to a hospital quickly in an emergency. You also might not want to travel long distances to get routine checkups and screenings. Rural areas often have fewer doctors and dentists, and certain specialists might not be available at all. Nearly 70% of all deaths, and 92% of deaths from communicable diseases, occurred among the poorest 20% of the population. Because it can be hard to get care, health problems in rural residents may be more serious by the time they are diagnosed. This research work aims to improve the health care facilities in the rural areas. It also aims at providing improved information and communication facilities between the health care officials and the rural population via various android applications. A mobile application has been developed which will help us monitor our blood pressure, sugar level, medicine intake pattern, provide us with proper notification at the time of medicine intake and assist in location based tracking of epidemics. A dedicated server program has been developed which will help medical officers to identify the possible candidate for a particular disease, send notifications and inform users at the time of vaccination schedule.

CHAPTER 1 INTRODUCTION
1.1 Overview India is the second most populous country of the world and has changing socio-political demographic and morbidity patterns that have been drawing global attention in recent years.
Despite several growths orientated orientated policies adopted by the government, the
widening economic, regional and gender disparities are posing challenges for the health sector. About 75% of health infrastructure, medical man power and other health resources are concentrated in urban areas where 27% of the population lives. Contagious, infectious and waterborne diseases such as diarrhea, amoebiasis, typhoid, infectious hepatitis, worm infestations, measles, malaria, tuberculosis, whooping cough, respiratory infections, pneumonia and reproductive tract infections dominate the morbidity pattern, especially in rural areas. However, non-communicable diseases such as cancer, blindness, mental illness, hypertension, diabetes, HIV/AIDS, accidents and injuries are also on the rise. The health status of Indians, is still a cause for grave concern, especially that of the rural population. This is reflected in the life expectancy (63 years), infant mortality rate (80/1000 live births), maternal mortality rate (438/100 000 live births); however, over a period of time some progress has been made. To improve the prevailing situation, the problem of rural health is to be addressed both at macro (national and state) and micro (district and regional) levels. This is to be done in a holistic way, with a genuine effort to bring the poorest of the population to the centre of the fiscal policies. A paradigm shift from the current „biomedical model‟ to a „sociocultural model‟, which should bridge the gaps and improve quality of rural life, is
the current need. It is unfortunate that while the incidence of all diseases are twice higher in rural than in urban areas, the rural people are denied access to proper health care, as the systems and structures were built up mainly to serve the better off. While the 7
urban middle class in India have ready access to health services that compare with the best in the world, even minimum health facilities are not available to at least 135 million of rural and tribal people, and wherever services are provided, they the y are inferior.

The basic nature of rural health problems is attributed also to lack of health literature and health consciousness, poor maternal and child health services and occupational hazards. The majority of rural deaths, which are preventable, are due to infections and communicable, parasitic and respiratory diseases. Infectious diseases dominate the morbidity pattern in rural areas (40% rural: 23.5% urban). Waterborne infections, which account for about 80% of sickness in India, make every fourth person dying of such diseases in the world, an Indian. Annually, 1.5 million deaths and loss of 73 million workdays are attributed to waterborne diseases. To improve the prevailing situation, the problem of rural health needs to be addressed in a very efficient manner. This research work focuses on this aspect [1][2][3].
1.2 Scope of the the project project This research work aims to improve the health care facilities in the rural areas. It also aims at providing improved information and communication facilities between the health care officials and the rural population. This research work focuses on various aspects of health care facilities and it can be broadly classified into two areas: a) Personal health care b) Primary health care

The personal healthcare aspect focuses on the following areas:
Consultational advice
Reminders for medicine patterns
Monitoring medication of elders
Monitoring daily lifestyle
The primary healthcare aspect focuses on the following areas:
Child and maternal care
Early learning of outburst of epidemics
Location based tracking of epidemics
Identifying possible candidate for a particular disease
Statistics and surveys

CHAPTER 2 RELATED WORKS Some firms have started using mobile technologies and smart networks to improve the quality of care, reduce costs, and contribute to a healthier world. American Telephone and Telegraph Company [AT&T]'s mHealth Solutions are a new set of IT solutions for healthcare that combine mobility technologies, devices, connectivity and applications to help drive down medical costs and deliver improved patient outcomes. AT&T Managed Tablets is a highly-secure, end-to-end management solution bundling software and services with certain tablets that is easy to purchase and deploy. AT&T mHealth Solutions presents DiabetesManager is an initiative between AT&T and WellDoc, which combines the DiabetesManager application and feedback engine with AT&T's highlysecure hosting environment, support and customer care [12].
Another venture is ashametrics which provides mobile health solutions and tools for a healthier life. Ashametrics enables patients and clinicians the ability to collect physiological data on a mobile phone and upload it to a medical record database. Ashametrics LifeBands are soft wearable textile bands that measure physiology and transmit data wirelessly to a mobile phone or nearby PC. Lifebands can also be used to record/log data internally and downloaded later via Bluetooth or USB. The AshaView software enables real-time monitoring and recording of physiological data. The mobile application supports simple plotting, real-time annotation, and the ability to configure all the settings on the Ashametrics LifeBands (such as sampling rate, date/time,and patient ID). Up to seven sensor bands can be connected simultaneously. Data can be downloaded to a PC via USB for post-processing. The basic version of the AshaView mobile application is available for FREE in the Andoid Market [15].

CHAPTER 3 AMRITA MOBILE HEALTH SOLUTION
3.1 Overview Amrita Mobile Health Solution [AMHS] focuses on two main aspects of healthcare, personal healthcare and primary healthcare. The personal healthcare aspect focuses on the following areas: a) Consultational advice – the user will be provided with an interface in his mobile in which he can enter the readings of pressure and sugar level and it will ed for be stored in the user‟s database. If a similar pattern of information is enter ed 3 or more days, then the mobile can show a message indicating whether to consult the doctor or whether his values are normal or not. Here the mobile will be acting as a knowledge base. b) Reminders for medicine patterns – Alarms can be set on the time when the medicine has to be taken. It will display which medicine has to be taken and also its dosage. c) Monitoring medication of elders – An UI can be created in which the user has to tap the button after he had taken a particular medicine. It can be set as on tapping the button the information that he had taken a particular medicine will be sent to the intended person and also the information will be stored in the user‟s
database. d) Monitoring daily lifestyle – It focus on recording the person‟s pressure and sugar level, intake of medicines etc on a daily basis and by analyzing these data the medical officer can monitor the lifestyle of the person and can advice on improvements if needed. 13
The primary healthcare aspect focuses on the following areas: a) Child and maternal care – It focuses on maternal and childcare. Our main focus is to help prevent various diseases like tuberculosis, diphtheria, pertusis, tetanus, polio and measles in children by timely alerting the parents about the date and time of vaccination via mobile. The information whether the vaccine has been given or not will be recorded in the user‟s as well as healthcare office‟s
database so that it can prove useful in future. It also focuses on maternal care. The details regarding the pregnant women will be stored in the healthcare office‟s database and they will be alerted regarding the various injections and
vaccines to be taken during the maternity period.

b) Early learning of outburst of epidemics – By monitoring the data received from the people, the medical officer can detect the outburst of any epidemics at a very early stage. c) Location based tracking of epidemics – By monitoring the data received from the people, the medical officer can find out in which area a particular disease is getting spread. d) Identifying possible candidate for a particular disease – By monitoring the lifestyle of a person the medical officer can detect the chances of any disease in future. e) Awareness messages – This module provides with the message sending facility to all the registered users informing them about medical camps, health tips and other health care related information.
The server side focuses on patients‟ personal details as well as medical history. It focuses on the following aspects: a) Patient registration b) Record updating c) Record deletion d) Information retrieval e) Report generation
The server also receives all the medical information sent from various users via android mobiles and stores them in the database for future references. It is the server that calculates the dates based on immunization schedule and sends SMS to the intended person‟s mobile informing them about the date of vaccination.

3.3 Operating Environment Environment The Amrita Mobile Health Solution is developed using the latest mobile technology android. Android is a free, open source mobile platform. It includes operating system, middleware and key applications. It is developed by Google and Open Handset Alliance in 2007. Android is built on the open Linux Kernel. Furthermore, it utilizes a custom virtual machine that has been designed to optimize memory and hardware resources in a mobile environment. Android is an open source; it can be liberally extended to incorporate new cutting edge technologies as they emerge. The platform will continue to evolve as the developer community works together to build innovative mobile applications. The various characteristics of android are:
Data transmission using Wi-Fi, GSM, EDGE, CDMA, EV-DO and UMTS.
It has a rich set of libraries for audio, video and image files.
Dalvik Virtual Machine
SQ-Lite for data storage.
IPC message passing facilities.
Integrated browser
Comprehensive libraries for 2D and 3D graphics.
Have features for video camera, touch screens, GPS etc.
The advantages of android include: • Its an open platform. platform. This means that its code is available for people
to look at. at.
• We can switch from one application to another with minimal changes. • Android allows third parties to make applications for the phone that can be installed by
anyone. • An Android phone is guaranteed to work with Google products.
17
• Android platform will work on notebook and computers. This means that you could
have device that share the same platform giving you the ability to purchase applications that will work on all devices. devices. • Multitasking • Android gives better notification. • Application freedom is guaranteed. • Android allows customization of home page and use of widgets.
To develop android applications the following software needs to be installed on our system: • Java Development Kit [ JDK] • A compatible Java IDE [ Eclipse] • Android SDK tools and documentation • Android Development Tools[ ADT] plug-in for Eclipse
The healthcare office system i.e., the server is coded using the popular programming language java. Java is a general-purpose, concurrent, class-based, object-oriented language that is specifically designed to have as few implementation dependencies as possible. It is intended to let application developers "write once, run anywhere" (WORA), meaning that code that runs on one platform does not need to be recompiled to run on another. Java is currently one of the most popular programming languages in use, particularly for client-server web applications.
18
To send and receive SMS text messages to cell phones from a JAVA application the Ozeki JAVA SMS SDK is used. It was designed to be used in JAVA applications that have a GUI or that operate as a background service. The SMS technology was created to provide an infrastructure for the transportation of short messages containing a maximum of 140 bytes (8 bit objects) of useful data in mobile telecommunication networks. The transportation is done in the GSM signaling path in traditional GSM networks, and as GPRS packets in GPRS networks. Messages are composed using the PDU specification. An SMS is a binary string containing all the necessary information to form the message header needed for transportation and the message body containing the payload. The basic addressing scheme of SMS messages are mobile telephone numbers called MSISDN. Ozeki has released the Java SMS SDK to add SMS functionality to JAVA applications in a very efficient way. This SDK communicates with the Ozeki NG SMS Gateway, through a TCP/IP socket. The socket is always connected, which makes it possible, to receive SMS delivery reports and incoming SMS messages instantly. The Ozeki Java SMS SDK implements the TCP/IP communication and provides methods calls and events you can implement to achieve the desired functionality. Using this SDK very fast and efficient SMS solutions can be developed. To be able to use this SDK, you need to install Ozeki NG SMS Gateway into your corporate network. Ozeki NG SMS Gateway will be responsible for attaching your system to the mobile network. It will receive the TCP/IP connections from the JAVA SMS SDK and it well send and receive SMS messages through the configured communication method [14].

CHAPTER 4 SYSTEM DESIGN
The system design is to deliver the requirements as specified in the feasibility report. The main objectives of the design are practicality, efficiency, cost, flexibility and security. The system design contains logical design and physical design.
4.1 Logical design The logical design of a system pertains to an abstract representation of the data flows, input and output of the system. This is often conducted via modeling which involves a simplistic representation of an actual system. Here modeling is done using Data Flow Diagram [DFD]. DFD is a hierarchical graphical model of the system that shows the different processing activities or the functions that the system performs and the data interchange between these functions. The DFD which is the top level view of the Information System is called context diagram [16].
20
21
22
4.2 Physical design The physical design relates to the actual input and output processes of the system. This is laid down in terms of how data is inputted into the system, how it is verified/authenticated, how it is processed, how it is displayed as output [16].
23
24
25
4.3 Database design A database is a set of logically related files organized to facilitate access by one or more application programs and to minimize data redundancy. The most important aspect of building an application is the design of tables or the database schema. The overall objective in the process of table design has been to treat data as an organizational resource and as an integrated whole [16].

CHAPTER 5 ADVANTAGES OF THE SYSTEM
The proposed system is user-friendly. The system does not require any extra hardware and hence the system is cheap. The user does not require any extra knowledge to operate the application installed in his/her android based smart phone. The application developed support all smart phones with android version 2.3.3 and above. The proposed system is portable and low cost and it makes it a system for the common man. The system is reliable and robust.
30
CHAPTER 6 APPLICABILITY OF THE SYSTEM
The system can be implemented in any rural area for healthcare assistance. Though the system is designed for rural population, it can also be used in urban areas as well. The server system can be implemented in the National Rural Health Mission [NRHM] health centre. The system can be implemented not only in NRHM centre but also in other medical care offices to keep track of the medical records of the people in that locality as well as give medical assistance in times of need. The application developed is very user friendly that it can be implemented in any android smart phone and the common man can use it with ease.
31
CHAPTER 7 FUTURE ENHANCEMENTS
As the progress in life is advanced from known to known, the future of any software package lies in its ability to progress from the specified to the general. The basic structure of AMHS was designed in such a way that the incorporation of additional utilities and function could be accomplished very easily without any change in the basic design. The system can be enhanced by adding mew modules and giving more server side capabilities. One module that can be added is statistics and surveys i.e., instead of going to each door and collecting information, can send a SMS with an attached survey form which the user can use to fill in the details and send back through SMS and the healthcare officer can store the data in the office‟s database. In this work, a dedicated
server is being used, instead a framework can be developed which will allow users to communicate with any Hospital Information System using their android mobile.
32
CHAPTER 8 CONCLUSION
A mobile health application has been developed. This application can be used by any end user to manage his health as well as communicate with the rural healthcare centre and avail healthcare notifications. The application is developed for android mobiles. It is expected to live up to the objectives for which it was designed. There is a hope that this task management application will be utilized to its maximum and will do a good job in the long run.
