OBJECTIVE: To determine the relationship between patient-reported single numeric
ratings and actual scores obtained from a validated instrument, the Knee Outcome
Survey (KOS). BACKGROUND: Patient-reported outcome (PRO) measures are an
important component of patient management. Information obtained from PRO measures
can be used to prioritize goal setting, assist with clinical decision-making,
provide evidence for effectiveness of interventions, monitor progress, and assess
organizational or clinician performance. METHODS: Scores from the KOS activity of
daily living (ADL) and Sports subscales completed at the time of initial
examination of patients with patellofemoral pain (n = 29) were retrospectively
analyzed and compared to a single assessment numerical rating. RESULTS:
Bi-variate Pearson product correlation was used to determine association between
the KOS-ADL and KOS-Sports with respective single assessment numerical ratings. A
high correlation was observed between the KOS-ADL (0.85, p < 0.01) and KOS-Sports
(0.88, p < 0.01) with a single assessment numerical rating. CONCLUSIONS:
Administration and scoring of standardized outcome measures such as the KOS-ADL
and KOS-Sports require several minutes to administer but correlate well with a
single assessment numerical ratings. The high correlation of single assessment
numerical scores to actual KOS-ADL and KOS-Sports scores may provide support for
discretionary use of single numerical ratings during interim patient care visits
and/or in instances when time is limited. Additional studies are needed with
larger patient populations and specific diagnostic subgroups to determine
additional clinical relevance.
