Reflect on your experiences with the integration of new technology. How have these implementations affected the procedures that you perform at work? As the end user, it can be easy to overlook all of the important decisions that went into the finished product that you see before you.

In looking at the final data management screens, you may find yourself at the crossroads of two options. You may either 1) be ecstatic about the needed change that this system brought, or 2) frustrated because you feel the system brings new hurdles into your already busy day.

If you have ever experienced the latter option, the comment “I could have implemented a better system than this” may resonate strongly with you. Though research agrees that user input assists HIT designers, the development and implementation of new systems is not as straightforward as it may appear.

HIT development teams find themselves in constant phases of trial and error as they strive to meet the needs of all users within the proposed development timeline. Failure to achieve promised usability benefits can lead to increased costs and job complications. Applying effective strategies to overcome usability challenges is essential.
 

In this week’s Discussion, you move from the standpoint of the “outsider looking in” (end user) and place yourself into a real-world implementation example. To complete this Discussion, you evaluate a case study to determine where the implementation process took a wrong turn. Use this week’s Learning Resources to propose changes that could have put this operation on the road to success.

To prepare:

• Review      the Learning Resources, focusing on the TIGER Usability and Clinical      Application Design Collaborative.
• Consider      the “Best Practice Exemplars” provided in the course text Nursing      Informatics: Where Technology and Caring Meet.
• Review      “Case Study 1: A Usability and Clinical Application Design Challenge”      presented on page 238 of the course text Nursing Informatics:      Where Technology and Caring Meet. (see bottom of this page for the      case study)
• Determine      the causes of the noted usability challenges (i.e., human factors,      ergonomics, human-computer interaction), as well as potential usability      concerns experienced by staff during implementation. Consider the possible      design failures that lead to the usability challenges.
  
   
• What      strategies might you employ to overcome these HIT usability challenges and      concerns?
• Write a minimum of 550 words essay in APA format with a minimum of 3 references from the list of Required Readings below. Include all level one headings as numbere

post a cohesive response to the following:

• Place      yourself in the role of the clinical administrator tasked with      implementing the case study’s new health information technology system.

1) Evaluate the usability challenges that you faced during implementation as well as the factors that caused these challenges.

2) Determine whether these challenges were a result of implementation or design.

3) Formulate strategies for overcoming these usability challenges.

Case Study 1: A Usability and Clinical Application Design Challenge

A medical center implemented an EMR with orders, clinical documentation, and results retrieval to improve efficiencies and enhance patient safety in the perinatal units of a small medical center, including Labor and Delivery (L& D), NICU, and Newborn Nursery Selection process The system was installed elsewhere in this integrated delivery network The executives wanted a fast 6-month installation at the maximum Usability challenges Existing order sets and documents from other sites were not uploaded and tailored to this site.

Clinicians were asked to input individual orders (not acceptable). Needed computer terminals were ordered late and arrived the day of go-live. Clinicians competed for working terminals at the nurses’ stations Workflow among units was not considered or tested. Shared information such as mother’s blood type and L& D information was not available to NICU or Newborn Nursery, causing confusion about potential patient safety issues Generic training was given because the site tailoring was not done.

On go-live, users did not know where to locate information before it had changed in the lag between training and go-live Outcomes The clinicians had to endure an unnecessarily painful implementation and its potential patient safety impacts Working out usability issues took months after go-live

The system was tested/ validated for usability, design, and practice needs Education included practice changes along with how to use the system Developed a methodology to respond rapidly to end users Outcomes Standardized practice in three different acute care hospitals in 15 months Significant improvement in core measures and nurse-sensitive outcomes.

Assignment:

This week you will create a two-part Power Point to discuss the following:

Part one: Peplau was the first nursing theorist to identify the nurse–patient relationship as being central to all nursing care. Peplau valued knowledge, believing that the nurse must possess extensive knowledge about the potential problems that emerge during a nurse–patient interaction. Peplau’s theoretical work on the nurse–patient relationship continues to be essential to nursing practice.

Create a PowerPoint presentation describing the phases of the Nurse-Patient relationship as defined by Peplau.  Align your presentation with a current nursing practice example.

Part two: Provide a discussion of Orem’s Self-Care Deficit Theory.  What are the three related parts? Identify a current nursing practice example where Orem’s theory would be relevant. Use at least one evidenced-based research article to support your practice example.

Power Point should include at least 3 outside references and the textbook. It should include title and reference slides and be 14-20 slides.
