Most of important variables measured in medicine are in numerical forms or continuous in nature. New instruments and tests are constantly being developed for the purpose of measuring various variables, with the aim of providing cheaper, non-invasive, more convenient and safe methods. When a new method of measurement or instrument is invented, the quality of the instrument has to be assessed. Agreement and reliability are both important parameters in determining the quality of an instrument. This article will discuss some issues related to methods comparison study in medicine for the benefit of medical professional and researcher. METHOD: This is a narrative review and this article review the most common statistical methods used to assess agreement and reliability of medical instruments that measure the same continuous outcome. The two methods discussed in detail were the Bland-Altman Limits of Agreement, and Intra-class Correlation Coefficient (ICC). This article also discussed some issues related to method comparison studies including the application of inappropriate statistical methods, multiple statistical methods, and the strengths and weaknesses of each method. The importance of appropriate statistical method in the analysis of agreement and reliability in medicine is also highlighted in this article. CONCLUSION: There is no single perfect method to assess agreement and reliability; however researchers should be aware of the inappropriate methods that they should avoid when analysing data in method comparison studies. Inappropriate analysis will lead to invalid conclusions and thus validated instrument might not be accurate or reliable. Consequently this will affect the quality of care given to a patient.
Costs and Cost Analysis

We conducted a multi-institutional case study to identify the issues associated with the adoption of information and communication technology (ICT) in five private care hospitals in the Kingdom of Saudi Arabia. We conducted interviews with 37 respondents primarily comprising IT professionals. We found that there were three determinants of behavioural intentions in this case study: organisation objectives, facilitating conditions and social influence where there are no effects of performance expectancy or effort expectancy. In all five cases, none of the moderators (age, gender, experience and voluntariness) in the original united theory of acceptance and use of technology model were considered critically important by IT professionals. In the present paper, all qualitative elements such as themes, patterns and overarching in the data were analysed to reach a conclusion. In addition, the various perspectives of using ICT are discussed.

Introduction: Addressing motivation to lose weight among morbidly obese patients increases successful weight management outcomes. We aimed to understand the motivations and reasons why morbidly obese patients attending hospital-based weight management programmes wanted to lose weight. Methods: A qualitative thematic content analysis was used to analyse responses from a self-administered open-ended question, “What is the main factor why you want to lose your weight?”. A total of 225 new patients attending obesity clinics program run by endocrinologists, dietitians and occupational therapists in two tertiary hospitals in Klang Valley responded to the questionnaire. Results: Patients’ mean BMI was 45.6±8.05 kg/m2 . Four themes emerged and they are health, function, appearance and perceived stigma. Health, the most commonly inferred theme (84%), highlighted concerns over obesity complications and concomitant morbidities, which include infertility, impact on surgical procedures as well as general physical and psychological well-being. Patients regard being functional to care for themselves, family members, religious and career needs as the next most crucial theme (25.8%). They relate to the theme appearance (12.9%) by wanting to look and feel beautiful. The theme perceived stigmatization recount the time when they were mocked and laughed at for their appearance (3.1%). Conclusion: Patients with morbid obesity in this study had expressed their main personal motivational reasons to lose weight. Identifying and addressing these unique personal motivations in a focused approach is vital for health care professionals to manage the complexity of the health, social and psychological needs among patients with morbid obesity.
