What is Evidence-Based Practice (EBP) in Nursing?
Evidence-based practice in nursing is to integrate clinical expertise with the best available research evidence to make informed decisions in nursing care that suit the patients’ situations and preferences (McKibbon, 1998; Sackett et al., 1996).
Key Steps in EBP
| Step | Action |
| 1 | Forming a clinical research question |
| 2 | Searching for evidence |
| 3 | Assessing the evidence |
| 4 | Making clinical decision |

Step 1 Forming a Clinical Research Question
Health professionals have to formulate a clinical research question to an identified problem of the patients concerned. Consider the following case:
Case Scenario
You are a professional nurse and receive complaint from a patient about having abdominal pain and nausea after the abdominal surgery. A paralytic ileus has been diagnosed. Now, you are in need of conducting research to determine whether there is evidence to suggest that a simple intervention such as chewing gum postoperatively can help ease the problem.
A PICO framework can be used to help you identify the study group and proposed intervention when formulating the research question:
| Aspect | Question |
| Population (P) | What individual or group do we need to study? |
| Intervention (I) | What is the proposed action / treatment? |
| Comparison (C) | What other action / treatment are we comparing to? |
| Outcome (O) | What do we anticipate as an outcome? |
Research Question
In patients undergoing abdominal surgery, is there evidence to suggest that chewing gum postoperatively compared with not chewing gum can help ease postoperative ileus?
Step 2 Searching for Evidence
Based on the PICO framework, the following keywords can be identified for the search:
| Aspect | Identified Search Phrases | Suggested Keywords |
| Population (P) | Patients undergoing abdominal surgery | abdominal surgery |
| Intervention (I) | Chewing gum | gum chewing |
| Comparison (C) | Not chewing gum | - |
| Outcome (O) | Affecting postoperative ileus | postoperative ileus |
Conducting Search
When carrying out search, make sure you select appropriate sources and employ various search techniques for relevant results
Sources of Evidence
The following databases consist of e-journal articles that are suitable for topics in medicine and healthcare:
- MEDLINE with Full Text (EBSCOhost)
- CINAHL Complete (EBSCOhost)
- Cochrane Library
- PubMed Central (PMC)
- TRIP
- Nursing and Allied Health Collection (Gale)
- PsycARTICLES (ProQuest)
- Internurse (Mark Allen Group)
- Intermid (Mark Allen Group)
Search Techniques
Boolean Operators (i.e. AND, OR, NOT) can be used to conduct and refine search.
| Boolean Operator | Function |
| AND | Narrow the search by linking up keywords |
| OR | Broaden the search for results with either keyword and both keywords |
| NOT | Narrow the search by excluding unwanted keywords |
- To generate results that are more specific, add quotation marks around the keywords for searching as a phrase instead of individual words.
- Use parentheses to group keywords in the search
Examples
“abdominal surgery” AND “postoperative ileus” AND “gum chewing”
(“abdominal surgery” OR “colorectal surgery”) AND “postoperative ileus” AND “gum chewing”
("colorectal surgery" NOT "abdominal surgery") AND “postoperative ileus” AND “gum chewing”
Step 3 Assessing the Evidence
After identifying various useful materials, you can start the evaluation process:
- Evaluate the materials based on a number of criteria, including their currency, relevance and authority
- Evaluating materials is a critical step for health personnel to make correct judgment and decisions for the patients concerned. Thus, when conducting evaluation, please be patient and prudent.
- Remove materials that are not relevant to the case or information that you consider vague or inaccurate
For assessment details, please visit Resource Evaluation page.
Step 4 Making Clinical Decision
After all the materials have been assessed as valid, relevant and accurate, an informed clinical decision can be made by taking into account clinical expertise and the patients’ perspective. The better informed you are, the more likely you are able to provide appropriate treatment and high quality care for the patients.
