A Questionnaire Approach Based on the Technology Acceptance Model for Mobile Tracking on Patient Progress Applications

Healthcare professionals spend much of their time wandering between patients and offices, while the supportive technology stays stationary. Therefore, mobile applications has adapted for healthcare industry. In spite of the advancement and variety of available mobile based applications, there is an eminent need to investigate the current position of the acceptance of those mobile health applications that are tailored towards the tracking patients condition, share patients information and access. Consequently, in this study Technology Acceptance Model has designed to investigate the user acceptance of mobile technology application within healthcare industry. The purpose of this study is to design a quantitative approach based on the technology acceptance model questionnaire as its primary research methodology. It utilized a quantitative approach based a Technology Acceptance Model (TAM) to evaluate the system mobile tracking Model. The related constructs for evaluation are: Perceived of Usefulness, Perceived Ease of Use, User Satisfaction and Attribute of Usability. All these constructs are modified to suit the context of the study. Moreover, this study outlines the details of each construct and its relevance toward the research issue. The outcome of the study represents series of approaches that will apply for checking the suitability of a mobile tracking on patient progress application for health care industry and how well it achieves the aims and objectives of the design.


INTRODUCTION
The implementation of new technology applications to support Healthcare professionals practices requires systematic investments and guiding (McNish, 2001;Meijden et al., 2003;Grimshaw et al., 2004). There is evidence of using a new technology in healthcare industry with exploitation of specific recommendations and guidelines will improve the quality of actions in health care (Wollersheim et al., 2005).
Effective evaluation of healthcare information systems is necessary in order to ensure systems adequately meet the requirements and information processing needs of the users and healthcare organizations. We design a Technology Acceptance Model to investigate user acceptance of mobile technology within the healthcare industry. It proposes a research methodology that being employed to understand the objectives and requirements, design, develop and finally, validate the mobile technology.
Research methodology is defined as procedures, ways, methods and techniques that are employed to capture and gather all the required information for the purpose of the research issue. Methodology refers to that branch of philosophy that analyzes the principles and procedures of an inquiry in a particular discipline. It is generally a guideline for solving a problem that outlines specific components, example: Phases, tasks, methods, techniques, tools and outputs. There are various methods that can be employed in gathering information from different sources such as sampling, site visits and observation of the study environment, questionnaires, Science Publications JCS interviews, prototyping and joint requirement planning. These methods would be applied in order to validate and refine the proposed hypothesis and organized according to structure of study. Thus, the study is organized specially to reflect the proposed research methodology that would be applied to address the proposed research issue. Debates surrounding the field of research reveal two main principal research categories: Quantitative and qualitative. It is important to note that quantitative research has been associated with the positivist stance while qualitative research with the interpretative stance (Creswell, 2011). However, qualitative and quantitative should not be considered synonymous to interpretive and positivist views respectively. In addition, the possibility of qualitative and quantitative research to be either interpretive, positivist, or critical have been proposed. Qualitative research is a type of research that produces findings not arrived at by means of statistical procedures or other means of quantification and the purpose behind the research is the understanding of human experience in order to reveal both the processes by which people construct meaning about their worlds and to report what those meanings are. A qualitative research is considered to be an investigation process that explains social phenomenon through constructing, comparing, replicating, categorizing and classifying the object of the study. In other words, qualitative research is concerned with words rather than numbers (i.e., in data that is not quantifiable). On the other hand, quantitative research is research that relies on developing metrics (numbers) that can be used to describe the phenomena (objects and relationships) under study. It is a deductive process (i.e., logic based on rules, models and laws) consisting of measuring and analyzing the relationship between variables. This process reveals how often or how many people act in a particular way but it fails to answer the question of "why". Table 1 shows the comparison between qualitative and quantitative research.

MATERIALS AND METHODS
The decision of whether to carry out a qualitative or a quantitative approach lies on the researcher's assumptions (Kanaan, 2009). The present study is based quantitative approach and aquestionnaire is utilized for the purpose of meeting the objectives of the study. We decide on for a quantitative as it helps to provide a description of the trends in a population or a description of the relationships among its variables (Creswell, 2011). In addition to this advantage, a quantitative is also inexpensive to be conducted and it is less time consuming as it enables the researcher to acquire both quantitative scale and qualitative data from a large research sample. For this reason, a questionnaire design coupled with quantitative analysis was employed in the present study to examine the variables in the adoption model and to achieve evaluation of using mobile technology system for tracking patient condition. Moreover, a Likert Scale is applied for each set of questionnaires. The likert scale is designed to examine how strongly subjects agree or disagree with statements on a five-point scale with the following anchors: (1) Strongly disagree, (2) Disagree, (3) Nature, (4) Agree, (5) Strongly agree (Chomeya, 2010). In this study the proposed methodology was developed in five phases. For every phase has process step(s) and output for better understanding of what the main goal of every phase as presented in methodology section.

Sampling Technique
Sampling is a procedure that entails utilizing a small number of units in a given population as a basis for drawing conclusions regarding the whole population (Jemain et al., 2007). The sample is considered as a subset of the population comprising of some members selected from it (Al-Omari et al., 2008). We aim to be able to draw generalized conclusions based on the population under study.

Analysis Techniques
There are three objectives of implementing data analysis: (i) getting overview for the sample data and its attributes, (ii) testing the goodness of data and (iii) validating the proposed hypotheses.

Variable Measurement
The methodology applied in the study is based on the questionnaire approach. The objective of the questionnaire approach is basically to evaluate the Science Publications JCS mobile tracking system. The questionnaire contains: Personal information, perceived usefulness, perceived ease of use, user satisfaction and attribute of usability. All of these have a number of questions constructed to evaluate the effectives of the system mobile tracking model to the intended users.

Proposed Methodology
This methodology is developed based upon a combination of the available literature and the experiences of the author, who are actively involved with the development of using mobile technology in health care industry. Figure 1 shows the phases of a proposed research methodology. The sequence of the phases is not rigid. Moving back and forth between different phases is always required. It depends on the outcome of each phase which phase or which particular output of a phase, has to be performed next.
The arrows indicate the most important and frequent dependencies between phases.

Phase 1: Problem Background

Phase 4: Result
The last phase of proposed research methodology, it is the finale of a specific study effort. The output of this phase is documentation.

Technology Acceptance Theory
There are many theoretical perspectives have been developed in order to understand how end users make decisions to use technology applications. Theories provide tools to understand success or failure in implementation processes of new IT applications. The most dominant theories in IT research are Innovation Diffusion Theory (IDT) (Rogers, 1995), Theory of Planned Behavior (TPB) (Fishbein and Ajzen, 1975), the Unified Theory of Acceptance and Use of Technology (UTAUT) (Venkatesh et al., 2003;2012), the FITT framework (Ammenwerth et al., 2002) and the Technology Acceptance Model (TAM) (Davis 1989;Davis et al., 1989).
Technology Acceptance Model (TAM) (Davis, 1989;Davis et al., 1989) is possibly the most frequently used among all other theories (Ma and Liu, 2004;Kim and Chang, 2007;Yarbrough and Smith, 2007). TAM theory is based on principles adopted from Fishbein and Ajzen (1975) attitude paradigm from psychology, which specifies how to measure the behavior-relevant components of attitudes, distinguishes between beliefs and attitudes and specifies how external stimuli are causally linked to beliefs, attitudes and behavior. The theoretical model on which TAM is based is the Theory of Reasoned Action (TRA). TRA is a general model which is concerned with individuals' intended behaviors. According to TRA an individual's performance is determined by the individual's attitude and subjective norms concerning the behavior in question. In addition an individual's beliefs and motivation interact with existing behavior (Ajzen and Fishbein, 1980). The Technology Acceptance Model (TAM) determines the user acceptance of any technology perceived usefulness (PU) and perceived ease of use (PEOU) factors. PU defines as the degree to which an individual believes that using a particular system will enhance the task performance. PEOU defines as the degree to which an individual believes that using a particular system is free of physical and mental effort (Davis, 1989;Davis et al., 1989;Davis, 1993). The TAM suggests that intention to accept technology is determined directly by attitude, perceived usefulness and perceived ease of use. According to TAM individuals' intention to use technology determines the actual use of the application and attitudes toward technology affect the intention Davis and Venkatesh, 2004;Venkatesh et al., 2012).  (Venkatesh and Morris, 2000;Venkatesh et al., 2012), or organizational features such as training in computer use (Venkatesh, 1999;Venkatesh et al., 2012).
TAM theory is widely used in research contexts as well as with several types of technology applications (Chau and Hu, 2001;Lee et al., 2006;Raitoharju, 2007;Yarbrough and Smith, 2007). TAM uses for generating explanations for the factors of technology acceptance that are transferable to different user populations and different kinds of technologies.
Many different contexts and research constructions have conformed the validity of the TAM model (Ma and Liu, 2004;King and He, 2006), including in health care industry (Chau and Hu, 2002a;2002b;Chismar and Wiley-Patton, 2003).

JCS
In this study the TAM theory will be used for the purpose of this study, to structure the research process and to help enhance the understanding of the acceptance and use of mobile technology in health care industry. Individual factors such as age, gender and technology skills are external variables in the study. Perceived usefulness is assessed by means of the content and benefits of the mobile tracking on patient progress system and the barriers and facilitators to the implementation of the system. The functionality of the application described perceived ease of use of the system. Attitudes toward mobile technology are taken to consist of motivation to use portable devices, satisfaction with mobile and experience of the benefits of mobile.

RESULTS AND DISCUSSION
The standard software categorizes quality into functionality, Perceived of Usefulness, Perceived Ease of Use, User Satisfaction and Attribute of Usability. This study aims to design all these categories to investigate the user acceptance of mobile tracking on patient progress in health care industry. From the perspective of TAM, perceived ease of use, perceived usefulness, user satisfaction and attribute of usability are assumed to be related to the acceptance of a computer or technology system, in this study the acceptance of a mobile technology in tracking patient progress system.
High levels of user satisfaction are important to mobile tracking on patient progress system. The effects of four components of satisfaction, Perceived of Usefulness Satisfaction and Satisfaction of Perceived Ease of Use, User Satisfaction and Satisfaction of Attribute of Usability on overall satisfaction among physicians and nurses will investigate. It will discuss about effectiveness of the using mobile technology in healthcare industry.
