Cognitive burden in this context refers to the mental demands placed on people as they absorb complex medical information, track medications, and participate in treatment-related decisions. On the study’s total cognitive burden scale, caregivers averaged 42.79 points (standard deviation 11.03) compared with 33.68 points (standard deviation 11.79) among patients. Communication difficulties, which capture problems understanding and exchanging information with medical teams and with each other, averaged 15.89 points for caregivers versus 12.54 for patients. Support needs, reflecting the desire for practical help and resources, averaged 30.84 for caregivers against 26.21 for patients. The proportion of caregivers classified as having high cognitive burden reached 20.3 percent, more than double the 9.6 percent observed among patients.

The researchers used identical questionnaires for both members of each dyad, allowing paired comparisons within the same household. When the team ran multiple linear regression analyses to identify which factors were most strongly associated with caregivers’ cognitive burden, communication difficulties emerged as the dominant predictor, with a standardised beta coefficient of 0.49 (P < 0.001). Caregiving time exceeding eight hours per day was the next strongest contributor (standardised beta = 0.27), followed by caring for a patient in a relapsed or refractory phase or receiving palliative care (standardised beta = 0.22).

When asked what kinds of support would help most, caregivers ranked emergency warning cards, medication lists, and guidance on practical care skills at the top of their needs. The study’s conclusion calls for clinical interventions that formally incorporate caregivers into comprehensive care frameworks, with particular emphasis on structured communication support, practical care resources, and targeted assistance during critical disease phases such as relapse or the shift to palliative treatment.

As an observational cross-sectional survey, the study captures a snapshot in time and cannot establish causal relationships between communication difficulties, caregiving intensity, and cognitive burden. The findings describe the experiences of the enrolled dyads and identify associations that warrant testing in interventional research. Nevertheless, the dyadic design highlights a measurable asymmetry within families managing hematologic malignancies: the people coordinating care often experience greater informational and decision-making strain than those receiving treatment, and their support needs frequently go unmeasured in clinical practice.
