Pre-existing Comorbidity Burden and Patient Perceived Stroke Impact

Area of Science:

• Neurology
• Rehabilitation Medicine
• Public Health

Background:

• Pre-existing comorbidities can complicate stroke recovery.
• Patient-rated perceived impact of stroke has been under-investigated compared to observer-rated measures.
• Understanding the influence of comorbidity burden on patient perception is crucial for comprehensive stroke care.

Purpose of the Study:

• To examine the association between comorbidity burden and patient-rated perceived impact and overall recovery within one year post-stroke.
• To adjust for stroke severity, age, and sex in this analysis.
• To provide insights into patient-centered outcomes following stroke.

Main Methods:

• A cohort of 177 stroke survivors from Australia and New Zealand participated.
• Comorbidity burden was assessed using the Charlson Comorbidity Index (CCI).
• Patient-rated perceived impact and recovery were measured using the Stroke Impact Scale (SIS).
• Quantile regression models were employed to analyze the data.

Main Results:

• Significant negative associations were observed between CCI and SIS index scores at 3 and 12 months post-stroke.
• A one-point increase in CCI correlated with a decrease in SIS scores, indicating a greater perceived impact.
• Associations with overall recovery were significant at specific time points and quantiles.

Conclusions:

• Comorbidity burden is an independent predictor of patient-rated perceived impact in the first year after stroke.
• Incorporating patient-reported outcomes alongside traditional measures can enhance stroke rehabilitation strategies.
• This study emphasizes the value of patient perspectives in assessing stroke recovery.
