Writing Nursing Research Questions: A Comprehensive Guide

A well-developed clinical question comprises five essential elements: Patient/Problem, Intervention, Comparison, Outcome, and Time/Type of Question/Type of Study. Without a properly formulated clinical question, conducting research and finding relevant evidence can be challenging and time-consuming. To aid in crafting clinical questions, the PICOT (or PICO) framework is used. PICOT helps in identifying the most valuable information from current research, which is crucial for evidence-based nursing, a growing standard in healthcare settings. This guide aims to assist nursing students in mastering the art of writing PICOT nursing questions.

Understanding the PICOT Framework

PICOT stands for Patient/Population, Intervention/Indicator, Control/Comparison, Outcome, and Time/Type of Study/Type of Question. When constructing a PICOT question, each element should be carefully considered and defined.

Patient/Population (P):
Identify the specific characteristics of the patients or population you are studying, such as age, gender, ethnicity, and location.

Intervention/Indicator (I):
Describe the treatment, intervention, or diagnostic test you are implementing for the patients or population.

Control/Comparison (C):
Specify the alternative treatment or management strategy with which you will compare the intervention or indicator.

Outcome (O):
Define the specific, patient-relevant consequences or results expected from the intervention.

Time/Type of Study/Type of Question (T):
Determine the time period or clinical domain relevant to your question and consider the types of studies that may provide the necessary data.

Crafting a PICOT Nursing Question: Essential Tips

When formulating a PICOT nursing question, ensure that your question addresses at least three of the five components of a well-structured clinical question. In most cases, the only elements that can be omitted from the question are Time or Comparison.

Example PICOT Question

To illustrate the application of the PICOT framework, consider the following example:

Research Question: Do text message reminders (I) regularly sent to patients diagnosed with diabetes type 2 (P) lead to reduced chances of forgotten insulin doses (O) over a six-month treatment period (T) compared with no text message reminders (C)?

Seven Types of PICOT Questions

1. Therapy Questions:

Focus on choosing treatments that provide greater benefits than harm to patients. Consider the outcomes and costs associated with the treatment.

Example: In nursing home residents suffering from osteoporosis, do hip protectors (I) result in reduced injuries from falls, slips, and trips (O) when compared with drug therapy for osteoporosis (C) during their stay (T)?

2. Diagnosis Questions:

Aim to identify the nature or cause of a disease or injury through clinical evaluation.

Example: Are parent reports and self-reporting interviews (I) performed on children from ages 5–10 (P) more effective than parent reports alone (C) in diagnosing depression (O) over a month-long consultation process (T)?

3. Etiology Questions:

Seek to understand the cause or origin of a disease and identify factors that may predispose individuals to a particular disorder.

Example: Are non-smoking females exposed to secondhand smoke daily for ten years or longer (P) more likely to develop breast cancer (O) compared to non-smoking females not exposed to secondhand smoke daily (C)?

4. Prognosis or Prediction Questions:

Attempt to predict the course of a disease or condition.

Example: Does the telemonitoring of blood pressure in African-Americans with hypertension in urban areas (P) improve the control of blood pressure (O) over a six-month period (T) after medication initiation (I)?

5. Prevention Questions:

Address how to reduce the occurrence of diseases and identify and influence risk factors. These questions also focus on early diagnosis.

Example: In individuals who visit emergency rooms (P), do hand sanitization stations (I) result in reduced hospital infections (O) compared to no hand sanitization stations (C) over a 12-month pilot period (T)?

6. Intervention Questions:

Explore the treatment of a disease or disability.

Example: In Latino male teenagers with hepatitis B (P), how does Ibuprofen (I) compared to acetaminophen (C) affect the functioning of the liver (O)?

7. Meaning or Quality of Life Questions:

Investigate how patients experience specific phenomena.

Example: How do pregnant women just diagnosed with diabetes (P) perceive reporting details of their blood sugar levels to their healthcare providers (I) during the pregnancy period and six weeks after delivery (T)?

Conclusion

Writing PICOT nursing questions may initially seem formulaic, but once the framework is mastered, the process becomes easier.
