Patients and Physicians Fail to Predict Each Other’s Disease Severity Grading in Eczema and Psoriasis
ABSTRACT
Background:
Discordant severity grading (DSG) is a well-documented issue where patients and physicians grade disease severity differently. However, less is known about whether patients and physicians can accurately predict how the other perceives disease severity. This study examined prediction accuracy and factors influencing accuracy.
Objective:
This study examined prediction accuracy and factors influencing accuracy.
Methods:
We conducted a mixed methods study using 1. secondary analysis of 1053 patient physician pairs, and 2. semi-structured interviews with 16 patients and physicians. Quantitative analyses compared predicted and actual severity scores, with regression to identify significant variables. Qualitative data was analysed using grounded theory.
Results:
Physicians underestimated patients’ severity, while patients overestimated physicians’ grading, with over half of predictions inaccurate by ≥2 points. Female sex, having eczema over psoriasis and longer duration of disease increased discordance in patient predictions. Conversely, first visits and longer duration of disease reduced discordance in physician predictions. Qualitative analysis identified themes shaping perceptions, including preconceived beliefs, treatment centric consults, communication gaps, time constraints and re-evaluation of disease severity.
Conclusions:
Patients and physicians frequently misjudge each other’s perceptions of disease severity. Prediction accuracy is shaped by demographic, clinical, and interpersonal factors, underscoring the importance of improved communication and mutual understanding to minimise DSG and optimise care.
