Effect of integrated community neurology on utilization, diagnostic testing, and access

Area of Science:

• Neurology
• Health Services Research
• Primary Care Medicine

Background:

• The primary care medical home (PCMH) model aims to enhance healthcare value.
• Increasing demand for specialists, particularly for older adults with complex conditions, requires innovative care delivery models.
• Integrating specialty expertise within primary care is crucial for maintaining care coordination and continuity.

Purpose of the Study:

• To evaluate the impact of an integrated community neurology (ICN) model on healthcare utilization, diagnostic testing, and patient access.
• To compare the ICN model with traditional, non-colocated neurology practices.

Main Methods:

• A retrospective, matched case-control study comparing patients referred to ICN versus a non-colocated neurology practice.
• Propensity score matching was used to create comparable control groups.
• Administrative data analyzed diagnostic testing, visit utilization, and appointment wait times.

Main Results:

• Patients in the ICN model showed significantly lower odds of undergoing EMG testing (aOR 0.64) and brain MRI (aOR 0.60).
• ICN patients had reduced likelihood of subsequent outpatient neurology referral (aOR 0.62).
• The ICN model was not associated with increased emergency department visits, hospitalizations, or appointment wait times.

Conclusions:

• The integrated community neurology (ICN) model, when implemented within a primary care medical home (PCMH), can effectively reduce the need for extensive diagnostic testing.
• This integrated approach shows potential for optimizing specialist resource utilization and improving primary care efficiency.
