Patient-Level Minimal Clinically Important Difference Based on Clinical Judgment and Minimally Detectable Measurement Difference

Patient-level minimal clinically important difference based on clinical judgment and minimally detectable measurement difference: a rationale for the SF-36 physical function scale in the SPORT intervertebral disc herniation cohort.

STUDY DESIGN A proof of concept case study. OBJECTIVE To introduce and evaluate a method for identifying what constitutes a minimal clinically important difference (MCID) in the SF-36 Physical Function scale at the patient level. SUMMARY OF BACKGROUND DATA MCID has become increasingly important to researchers interested in evaluating patient care. Over the last 30 years, an array of approac...

The minimally clinically important difference in generic utility-based measures.

PURPOSE To evaluate the use of utility-based generic quality of life measures for establishing the minimally clinically important difference (MCID). BACKGROUND Utility-based quality of life measures place levels of wellness on a continuum anchored by death (0.00) and optimum function (1.00). Preference measurement studies are used to define the meaning of points along the continuum. Health st...

Health status measurement in COPD: the minimal clinically important difference of the clinical COPD questionnaire

BACKGROUND Patient-reported outcomes (PRO) questionnaires are being increasingly used in COPD clinical studies. The challenge facing investigators is to determine what change is significant, ie what is the minimal clinically important difference (MCID). This study aimed to identify the MCID for the clinical COPD questionnaire (CCQ) in terms of patient referencing, criterion referencing, and by ...

Assessing the Stroke-Specific Quality of Life for Outcome Measurement in Stroke Rehabilitation: Minimal Detectable Change and Clinically Important Difference

BACKGROUND This study was conducted to establish the minimal detectable change (MDC) and clinically important differences (CIDs) of the physical category of the Stroke-Specific Quality of Life Scale in patients with stroke. METHODS MDC and CIDs scores were calculated from the data of 74 participants enrolled in randomized controlled trials investigating the effects of two rehabilitation progr...
