Brainstorm a number of healthcare delivery or nursing practice

Brainstorm a number of healthcare delivery or nursing practice problems that could be explored using correlational statistics. Then, select one problem on which to focus for this Discussion. Formulate a research question to address the problem and that would lead you to employ correlational statistics. Develop a null hypothesis and alternate hypotheses. Ask yourself: What is the expected direction of the relationship? Post a brief description of the selected problem that you identified for the focus of this Discussion and include your research question. Be specific. Explain your null hypothesis and alternate hypotheses for your research question and identify the dependent and independent variables that you would recommend to best support the research study. Then, explain your prediction for the expected relationship (positive or negative) between the variables that you identified. Why do you think that sort of relationship will exist? What other factors might affect the outcome? Be specific and provide examples. break-it down to these paragraphs labeled. “Main post” “research question“ “Hypothesis“ ” purpose statement“ “variable and expected relationships” “rational for predicted relationships and contributing factors”

Sample Solution

Main Post

This discussion will focus on exploring the potential relationship between registered nurse (RN) staffing levels and hospital-acquired pneumonia (HAP) rates in intensive care units (ICUs).

Research Question

Does a correlation exist between registered nurse staffing levels (measured by the nurse-to-patient ratio) in adult ICUs and hospital-acquired pneumonia (HAP) rates among ICU patients?

Full Answer Section

Hypothesis

Null Hypothesis (H0): There is no statistically significant correlation between registered nurse staffing levels (nurse-to-patient ratio) in adult ICUs and hospital-acquired pneumonia (HAP) rates among ICU patients.
Alternate Hypothesis (Ha): There is a statistically significant correlation between registered nurse staffing levels (nurse-to-patient ratio) in adult ICUs and hospital-acquired pneumonia (HAP) rates among ICU patients.

Variables and Expected Relationships

Independent Variable: Registered nurse staffing levels (measured by the nurse-to-patient ratio) in adult ICUs.
Dependent Variable: Hospital-acquired pneumonia (HAP) rates among ICU patients.

We expect a negative correlation between the two variables. This means that as nurse-to-patient ratios decrease (indicating higher nurse staffing levels), HAP rates should also decrease.

Rationale for Predicted Relationships and Contributing Factors

Lower nurse-to-patient ratios allow for:

More frequent patient assessments and monitoring for signs of infection.
Implementation of preventative measures like meticulous hand hygiene and proper use of catheters.
Increased time for patient education and respiratory care techniques to reduce the risk of pneumonia.

Contributing Factors:

Severity of illness of ICU patients: Patients with compromised immune systems may be more susceptible to HAP regardless of staffing levels.
ICU unit design and layout: Units with private rooms may have lower HAP rates compared to open bay designs.
Use of travel nurses or less experienced nurses: Experience and continuity of care might influence infection control practices.

These are just some of the factors that might influence the relationship between nurse staffing and HAP rates. Correlational research can't establish causation, but it can help identify potential links that warrant further investigation.
