Centralized care model for hereditary angioedema overcomes geographical barriers

Area of Science:

• Immunology
• Genetics
• Public Health

Background:

• Hereditary angioedema (HAE) due to C1 inhibitor deficiency is a rare genetic disorder causing recurrent swelling episodes.
• Management involves on-demand treatment, short-term prophylaxis, and long-term prophylaxis (LTP), with parenteral administration posing challenges for some patients.
• Potential disparities in care exist for rural HAE patients due to complexities in treatment administration and access.

Purpose of the Study:

• To compare the quality of care for hereditary angioedema (HAE) between urban and rural patient populations.
• To assess differences in the utilization of long-term prophylaxis (LTP), age at diagnosis, and disease control.
• To evaluate the impact of a centralized care model on healthcare equity for HAE patients.

Main Methods:

• A cross-sectional study was conducted at a comprehensive HAE care clinic.
• Data on LTP use, age at diagnosis (childhood vs. adult), and disease control (using the Angioedema Control Test - AECT) were collected for urban and rural patients.
• Logistic and Poisson regression models, adjusted for age and sex, were used for comparative analysis.

Main Results:

• The proportion of patients receiving LTP was similar between urban (62%) and rural (61%) populations.
• The rates of childhood diagnosis were comparable, with 52% of urban patients and 60% of rural patients diagnosed as children.
• Mean AECT scores indicated similar disease control in both groups (urban: 14.0, rural: 13.0).

Conclusions:

• Rural patients with HAE receive care quality equivalent to their urban counterparts.
• A centralized, comprehensive care model effectively mitigates potential disparities in HAE management for rural populations.
• This model ensures equitable access to essential treatments like LTP and supports timely diagnosis and disease control.
