ABSTRACT
The innovation in Information and Communication Technology (ICT) has provided the future technology Internet of Things (IoT) with immense prospects and opportunities.
IoT is a network founded on the use of sensors, actuators, beams, Radio Frequency Identification (RFID) devices, and software in things that can transform the future healthcare into pervasive healthcare delivery. IoT-based healthcare system can improve the delivery of healthcare services efficiently and innovatively by growing huge volume of patients’ data (big data) that can invoke proactive, predictive decisions and insights in future healthcare of Pakistan. However, no prior research is conducted so far in the context of IoT-based healthcare in Pakistan. To fill the research gap, the study contributed to develop and validate proposed research model and investigated significant factors influencing the IoT-based healthcare adoption by the community, medical professionals (doctors, support staff, health administrators), and end-users specifically in underserved areas of Pakistan. The research study confirmed proposed research framework in the precision of UTAUT and HBM theories on a sample of 281 diverse medical professionals’ responses from five hospitals located in different cities of Pakistan. The research employed exploratory, descriptive, and causal approaches to test and validate the research hypotheses using Exploratory Factor Analysis (EFA), measurement model, Confirmatory Factor Analysis (CFA), and Structural Equation Modeling (SEM) statistical techniques. The empirical findings statistically confirmed that performance expectancy (PE), effort expectancy (EE), facilitating condition (FC), doctor-patient relation (DPR) were significant predictors in technological context whereas, perceived severity(PS) of health risk behavior was also a significant factor of IoT-based healthcare adoption. The factors, which had no statistically significant impact, included perceived susceptibility (PSS) of health risk, social influence (SI), and trust (TR). These research findings are expected to improve prevailing healthcare in underserved areas and potentially benefit several stakeholders such as the healthcare service providers, health insurance companies, and remote healthcare providers, and designers of IoT-based health information systems in future.

CHAPTER ONE INTRODUCTION
1.1 OVERVIEW
This research studies the new smart innovation of Information and Communication Technology (ICT) available today in healthcare, IoT-based or smart healthcare, focusing on innovation adoption, specifically the factors determining usage intention. This study is to recognize and measure the motivational factors that would expedite the introduction and pervasive use of IoT-based healthcare services and improve prevailing conditions of healthcare in under-served areas of Pakistan. Developing countries like Pakistan have the main goals to provide access to medical services for the population living in rural areas and to use proficiently limited healthcare resources (Babar Tasneem Shaikh Arslan Mazhar and Assad Hafeez, 2013).
This marvel has been depicted as the versatile wonder, and has driven wide societal and monetary changes. Without a doubt, smart devices utilization has changed the way individuals impact, as well as the way they plan their everyday lives, arrange themselves socially, and get to informative, business, employment and healthcare managing opportunities. Modern Information Systems (IS), more specifically the new trend announced these days: the Internet of Things (IoT) or Internet of EveryThing (IoE), has immense prospectus and opportunities in supporting and managing healthcare cost, and improving quality of care (Daim, Behkami, Basoglu, Kök &
Hogaboam, 2016). IoT is a network of networks, in which typically a massive number of smart objects (smart phones, smart watches, smart glasses, smart TV etc.), things, sensors or devices are connected through the information and communication

technology to provide value-added services. IoT and its potential can provide new solutions to almost every aspect of daily activity. The IoT is the perfect storm of advanced sensors, real time networks, and massive data centers (Jwilliams, 2015). It is internationally recognized that Internet of Things (IoT) will support future healthcare systems in order to target the upcoming societal health challenges. Therefore, in future IoT-based healthcare is going to equip the traditional healthcare with advanced smart solutions in a new way to assess, assist, and treat the patients remotely or wherever the patient may be. By using Internet enabled devices like smart health sensors, actuators, beams, Sensor Shield V2.0 (SSV2), and smartphone apps etc. In future, there is change in tendency of healthcare with invention of medical wearable devices shift towards patient centric healthcare from hospitals to patient wherever he/she may be at home, workplace or on travel (Islam, Kwak & Kabir, 2015). In Internet of Things, the network is founded on the use of sensors, actuators, beams, RFID devices and software in things that can transform the future healthcare into pervasive healthcare. The use of sensors, actuators, beams, radio frequency identification (RFID) devices, and software in smart things can transform healthcare into pervasive healthcare, so it may improve future healthcare, its related issues to delivery, management, and development. IoT in the healthcare, for example, Physician may embed biological sensors in the body of the patient to measure blood pressure (BP), electrocardiogram (ECG), heartbeat, and oxygen saturation in order to better determine cardiac patient condition remotely and react before some vulnerabilities appear. It is clear that their purpose is to enable better healthcare. One can then easily extend IoT technology to a patient monitoring system (Agilent, 2015). “Things are potentially autonomous, semi-autonomous or not autonomous” (O’Leary, 2013). However, the sensor instruction, actuators, beams, and software may breed artificial intelligence into Internet of Things to act completely
