Physical Therapy - Dallas: EBP

Physical therapy research guide for TWU Dallas students, faculty, and staff.

What is EBP?

A way of providing health care that is guided by a thoughtful integration of the best available scientific knowledge with clinical expertise. This approach allows the practitioner to critically assess research data, clinical guidelines, and other information resources in order to correctly identify the clinical problem, apply the most high-quality intervention, and re-evaluate the outcome for future improvement. (PubMed MeSH)

Viva La Evidence

by James McCormack   (4min 19sec)

Locating Evidence using P I C O Questions

Locating evidence in literature depends upon asking an effective research question. Use the PICO mnemonic to build that question.

P I C O

     P -- patient, population, participant
      I -- intervention, therapy
     C -- comparison  (not always required)
     O -- outcome


 4 Types of PICO Questions

     1. Diagnosis
     2. Prognosis
     3. Therapy
     4. Etiology

      

Examples

Diagnosis PICO:
In children with respiratory infection, is the respiratory rate as effective as chest x-ray in detecting pneumonia?

Prognosis PICO:
In premature infants (compared to full-term infants), what is the lifetime prevalence of hearing deficit?

Therapy PICO:
In patients with recurrent infection, do antibiotics, compared to no treatment, reduce recurrence rate?

Etiology PICO:
In post-menopausal women, does hormone replacement therapy increase the risk of breast cancer?

Searching for Evidence-Based Practice

A way of providing health care that is guided by a thoughtful integration of the best available scientific knowledge with clinical expertise. This approach allows the practitioner to critically assess research data, clinical guidelines, and other information resources in order to correctly identify the clinical problem, apply the most high-quality intervention, and re-evaluate the outcome for future improvement (PubMed MeSH).
