Wk 1: Patient Outcomes and Clinical Measurements Flashcards
Outcomes
ultimate validation of the effectiveness and quality of medical care
Evaluating outcomes
result of interventions, self management, system of care and individual factors
CNS competency r/t outcomes
Direct care- measurement of outcomes is essential for CNS to evaluate the efficacy of interventions delivered at ind. pt. level
Regulatory Agencies
CMS Core Measures, NDNQI
Outcome measures
assessed for appropriateness and rigor (reliability & validity)
Nurse Sensitive Outcomes
improve quantity or quality of nursing care
Patient reported outcomes (PRO)
Patients subjective complaints
Patient reported outcomes measures (PROM)
performance measures. National Quality Forum (NQF), National Committee for Quality Assurance (NCQA).
Rationale for PRO
better symptom control and QOL are associated with reduced costs and use of medical services and improved medication compliance, patient satisfaction and survival.
Appraisal of tools to enhance EBP
Correct Problem, Does the Conceptual basis of instrument match my own, Was tool developed for same purpose as mine, Does tool have adequate reliability, validity, S&S, Tool easy to use
Define Clinical Problem
Do you have significant problem where there is insufficient literature?
Conceptual basis
disciplinary perspective and nature of clinical problem
Nature of clinical problem
static or dynamic
Modified Borg Scale
rating scale to match nurses point of view
Parameters of instruments
purpose, aim, population and time orientation
Reliability
consistency of insturment
Types of Reliabilty
Stability, equivalence, internal consistency
Stability
test-retest method and parallel forms, 0-1.0- closer to 1.0 is better
Equivalence
interrated and parallel forms. Interrater should be at least 90% or correlation approaching 1.0
Internal Consistency
how well a tool measures a single concept or how well the concepts intercorrelate. Measure 0-1.0, with .7 to .9 considered adequate.
Validity
How well the instrument measures what it is supposed to
Types of Validity
content criterion, construct
Changes with validity
All validity considered construct: 5 categories of evidence- test content, response process, internal structure, relation to variables, consequence of testing
More reports of validity
more evidence to demonstrate validity of instrument
