Assignment: Primary Question Types

Week 8 – Assignment 1 Discussion The discussion for this week will revolve around the analysis phase of your project. Include the following points in your discussion: Begin with a brief description of your project that includes your clinical question, your planned intervention, the type of study you will conduct and how you plan to evaluate the outcomes. What type of statistical analysis will be done? What is a reasonable timeline for your project? What expenses should be considered? Include both obvious expenses, such as materials, as well as those that are hidden, such as time, which equates to part of your salary. Will you need to consider a funding source for your project?

A clinical question needs to be directly relevant to the patient or problem at hand and phrased in such a way as to facilitate the search for an answer. PICO makes this process easier. It is a mnemonic for the important parts of a well-built clinical question. It also helps formulate the search strategy by identifying the key concepts that need to be in the article that can answer the question.

PICO or PICOTT:

PATIENT OR PROBLEM
How would you describe a group of patients similar to yours? What are the most important characteristics of the patient?

INTERVENTION, EXPOSURE, PROGNOSTIC FACTOR
What main intervention are you considering? What do you want to do with this patient?

COMPARISON
What is the main alternative being considered, if any?

OUTCOME
What are you trying to accomplish, measure, improve or affect?

Type of Question
Therapy / Diagnosis / Harm / Prognosis / Prevention

Type of Study
Systematic review / RCT / cohort study / case control

Primary Question Types

• Therapy: how to select treatments to offer our patients that do more good than harm and that are worth the efforts and costs of using them.
• Diagnostic tests: how to select and interpret diagnostic tests, in order to confirm or exclude a diagnosis, based on considering their precision, accuracy, acceptability, expense, safety, etc.
• Prognosis: how to estimate a patient’s likely clinical course over time due to factors other than interventions
• Harm / Etiology: how to identify causes for disease (including its iatrogenic forms).

Other Question Types

• Clinical findings: how to properly gather and interpret findings from the history and physical examination.
• Clinical manifestations of disease: knowing how often and when a disease causes its clinical manifestations and how to use this knowledge in classifying our patients’ illnesses.
• Differential diagnosis: when considering the possible causes of our patient’s clinical problem, how to select those that are likely, serious and responsive to treatment.
• Prevention: how to reduce the chance of disease by identifying and modifying risk factors and how to diagnose disease early by screening.
• Qualitative: how to empathize with our patients’ situations, appreciate the meaning they find in the experience and >understand how this meaning influences their healing.
