quantitative research in medical field examples

The committee is now known as the Medical Research Council (MRC). Note that validity evidence for the scores of a measurement instrument is separate from the internal validity of a research study. Knowing and understanding these assets and liabilities can help you decide if this research plan is the one for you. Examples of ordinal variables may include measurements of satisfaction (satisfied vs. unsatisfied), agreement (disagree vs. agree), and educational experience (medical student, resident, fellow). Effect of the BASIC examination on knowledge acquisition during anesthesiology residency. Extraneous load: Distractions or demands on short-term memory that are not related to the information the resident is trying to learn (e.g., background noise, interruptions). The objective was to implement a national scheme for health insurance which would provide hospital treatment for tuberculosis (TB) and to initiate research comparing TB in animals and humans. For instance, the difference in performance between second- and third-year medical students is dramatically different than third- and fourth-year medical students. In this final section, we identify instruments that can be used to evaluate the quality of quantitative medical education research articles. Imagine that researchers want to explore the relationship between burnout and educational debt among pain medicine specialists. To illustrate how different conceptual frameworks can be applied to a research problem, suppose you encounter a study to reduce the frequency of communication errors among anesthesiology residents during day-to-night handoff. Can we be confident that this survey administered to medical students is truly measuring teaching effectiveness? Sources of Validity Evidence for Measurement Instruments, Reliability refers to the consistency of scores for a measurement instrument.22,25,28  For an instrument to be reliable, we would anticipate that two individuals rating the same object of measurement in a specific context would provide the same scores.25  Further, if the scores for an instrument are reliable between raters of the same object of measurement, then we can extrapolate that any difference in scores between two objects represents a true difference across the sample, and is not due to random variation in measurement.29  Reliability can be demonstrated through a variety of methods such as internal consistency (e.g., Cronbach’s alpha), temporal stability (e.g., test–retest reliability), interrater agreement (e.g., intraclass correlation coefficient), and generalizability theory (generalizability coefficient).22,29, This section provides an illustration of validity and reliability in medical education. 2012; 4(3):279–82. John T. Ratelle, Adam P. Sawatsky, Thomas J. Beckman; Quantitative Research Methods in Medical Education. Dr. Richard Biehl, education coordinator of the online Master of Science in Health Care Systems Engineering program at the University of Central Florida, explains that QA stands to change the face of research in the health care field, because, suddenly, it may become very easy to test the strength of correlations between thousands of variables with the touch of a button. However, a well-designed study has limited value if it addresses vague, redundant, or unimportant medical education research questions. Quality of reporting of experimental studies in medical education: A systematic review. Measurement is of particular importance in medical education research because many of the constructs being measured (e.g., knowledge, skill, attitudes) are abstract and subject to measurement error.24  This section highlights two specific issues related to the trustworthiness of data: the validity and reliability of measurements. Under the terms of the licence agreement, an individual user may print out a PDF of a single chapter of a title in Oxford Medicine Online for personal use (for details see Privacy Policy and Legal Notice). Our Research Home » About Hennepin Healthcare Research Institute » Why Medical Research is Important The high quality of medical care we enjoy today is built upon years of effort by physicians, physician-scientists, PhDs, and other medical professionals investigating the causes of and potential treatments for disease. Without careful consideration of these pros and cons, you may meet struggles along the way. Quantitative research in medical education tends to be predominantly observational research based on survey or correlational studies. © Oxford University Press, 2021. Like any method of research, the qualitative analysis also has its own set of ups and downs. We use the term internal validity to describe the degree to which the findings of a research study represent “the truth,” as opposed to some alternative hypothesis or variables.18 Table 3 18–20  provides a list of common threats to internal validity in medical education research, along with tactics to mitigate these threats. I-pass, a mnemonic to standardize verbal handoffs. these title examples gives you an idea of quantitative research topic Different approaches to research encompass both theory and method. They found little variance was due to the rater (i.e., scores were consistent between raters), indicating a high level of reliability.7.
