Evidence based practitioners ANOVA

1
Evidence -based practitioners ANOVA

• Lecture 7, OT 667

2
What is evidence-based practice?

• An approach to decision-making in which the
  clinician uses the best evidence available
  combined with clinical expertise in consultation
  with the patient to decide upon the clinical
  options which suit the patient best

3
Factors to consider when making clinical decisions

• Patient Expectations
• Environment
• Past Experience
• Evidence
• Ethics

4
Patient Expectations

• Result of client/patient beliefs, values, life
  experiences, educational background, family hopes
• Location of patient in their health experience
  (new injury, chronic condition, life-threatening
  condition)
• Culture of the community
• Patient experience of the health care system

5
Environment

• Social environment
• patient-therapist interaction
• family involvement
• support of professionals/community in which the
  patient/client functions
• Physical environment
• where the treatment takes place
• where the patient/client lives and functions on a
  day to day basis
• equipment available to the clinician

6
Experience

• Length of time on the job
• Clinical community (where you practice)
• Continuing education

7
Ethics

• Professional codes
• Facility mission
• Personal beliefs/values
• Life realities

8
Evidence
9
How will you judge the effects of your clinical
decisions?

• client report
• use of tests
• judgement of other professionals (physicians,
  other therapists)
• compare results against other patients with
  similar diagnoses

10
How will you grow as a clinician in order to be
able to judge change? Learn new skills?
11
Growth Opportunities

• Advanced training (specialty courses)
• Conferences (local, regional, national)
• Involvement in local OT organizations

12
Evidence-based Review for Professional Growth

• objective assessment of outcomes as a result of
  systematic study
• introduction of new assessments and techniques
• introduces new trends in theory and policy, which
  affect patient care
• challenges modes of thinking

13
Being Open to Evidence

• How do you feel when beliefs you hold strongly
  are challenged?
• How do those feelings affect your subsequent
  behavior?

14
Analysis of Variance
15
What is analysis of variance? (ANOVA)

• A statistical procedure for comparing three or
  more conditions or groups to see if the
  difference among a set of means are greater than
  would be expected by chance alone. Results are
  based on the F statistic, a ratio of between
  groups effects to within group variability.

16
Different Forms of ANOVA

• One-way ANOVA
• Repeated measures ANOVA
• Two and three -way ANOVA (factorial designs)
• Mixed designs, where one factor is repeated but
  another is held constant (factorial designs)
