NURS 6431: Evaluation Methods for Health Information Technology | Week 3

As you associate with family, friends, and colleagues, you may have noticed that some individuals are always the first to use a new technology and are comfortable with doing so. Meanwhile, others seem to be the last to switch to any new technology and often are hesitant to do so. Dr. Everett Rogers, a prominent sociologist in the study of innovation, developed a model to describe the adoption of new technologies. He identified the types of individuals who will adopt first and the conditions that promote the adoption of new technology by others. Rogers’ model, Diffusion of Innovations, has been used as the foundation for research in fields as diverse as agriculture, marketing, health care, and health informatics.

Scientific inquiry and research should always be built upon models. Such models provide the lens through which to view a subject matter. Effective health informatics evaluation plans are always based on an underlying model. This week, you are introduced to four of the key models used in health informatics evaluation.

Learning Objectives

Students will:

  • Analyze the use of a model as a component of health informatics evaluation
  • Assess the impact of goals and viewpoint on evaluation planning
  • Create graphic representations of research models in information technology evaluation

Have you ever watched a movie in which the same scene was shown several times but as viewed by different individuals? Or, have you watched a detective show in which the witnesses all had differing accounts? The same can hold true for conducting an evaluation of a health information technology project. How you plan and conduct the evaluation is largely dependent on the viewpoint you assume and the perspective with which you approach the evaluation.

Consider a new patient discharge protocol at a small hospital. Do you want to know how the patient feels about the process? Do you want to gather the opinions of nurses who are using this process? Perhaps you want to determine if it is saving the hospital money by freeing up bed space in a more timely fashion. Obtaining each of these viewpoints would require a different approach. Depending on the goal of your evaluation, the model and viewpoint you opt to use will likely vary.

In this Discussion, determine which evaluation model would be most effective for evaluating the health information technology described in one of the scenarios below. Your Instructor will assign a specific scenario by Day 1 of this week.

  • Scenario 1: You have recently provided a training program to help nurses and physicians become proficient in the use of a new bedside medication verification (BMV) system.
  • Scenario 2: The Chief Medical Officer at your hospital is interested in finding out the impact of a new decision support system on the number of adverse events occurring in the past year.
  • Scenario 3: You are helping with the design of a new outpatient surgery center to be built adjacent to the hospital. You are tasked with evaluating the opinions of physicians, nurses, and the general public toward this facility.

To prepare:

  • Review the information on the types of evaluation models covered in this week’s Learning Resources.
  • Determine which model would be most appropriate to use for evaluation in the scenario to which you were assigned.
  • Consider why the viewpoint of the scenario or situation would impact the model used.
  • View the scenario from a different viewpoint, and consider how a different model might be used.
  • Reflect on the importance of basing an evaluation on a model.

By Day 3

Post which scenario (1, 2, or 3) you were assigned and two different models that could be utilized to approach the evaluation. Explain why you selected those models and how you would use them. Explain why it is important to consider the intended goal of the evaluation and the viewpoint that is selected. Finally, assess the importance of basing an evaluation on a model. Justify your response.

By Day 6

Respond to at least two of your colleagues on two different days, using one or more of the following approaches:

  • Ask a probing question, substantiated with additional background information, evidence, or research.
  • Offer and support an alternative perspective using readings from the classroom or from your own research in the Walden Library.
  • Make a suggestion based on additional evidence drawn from readings or after synthesizing multiple postings.
  • Expand on your colleagues’ postings by providing additional insights or contrasting perspectives based on readings and evidence.
