A critical look at transition ratings

Area of Science:

• Clinical research
• Health outcomes measurement
• Patient-reported outcomes

Background:

• Transition ratings are frequently used in clinical practice and research to assess patient improvement or deterioration.
• Concerns exist regarding the validity of these transition ratings.
• Health-related quality of life (HRQL) instruments are often used alongside transition ratings.

Purpose of the Study:

• To examine the validity of patient transition ratings.
• To explore the relationship between disease-specific HRQL instrument scores and corresponding transition ratings.
• To determine if pre- and post-intervention scores adequately predict transition ratings.

Main Methods:

• Analyzed data from three studies correlating HRQL instrument domains with transition ratings.
• Focused on comparisons with a correlation of at least 0.5 between HRQL domain scores and transition ratings.
• Used regression analysis to assess the predictive power of pre- and post-scores on transition ratings.

Main Results:

• Of 14 comparisons, only three showed ideal correlations between pre/post scores and transition ratings.
• Regression coefficients were similar to ideal patterns in eight comparisons.
• Pre-scores significantly explained variance in transition scores in most cases when controlling for post-scores.

Conclusions:

• Transition ratings rarely exhibit the theoretically ideal association with pre- and post-intervention scores.
• Pre-intervention scores generally show significant correlation and predictive value for transition ratings.
• Researchers should validate transition scores by examining their relationship with corresponding pre- and post-domain scores.
