Integrated Delivery Networks Facilitate Diabetic Eye Examination Completion and Communication.

Area of Science:

• Health Services Research
• Ophthalmology
• Endocrinology

Background:

• Integrated Delivery Networks (IDNs) aim to improve care coordination for chronic conditions like diabetes.
• Effective communication between eye care specialists and primary care providers (PCPs) is vital for managing diabetes complications.
• Leakage, or care received outside the IDN, can disrupt coordinated management and impact patient outcomes.

Purpose of the Study:

• To identify factors associated with receiving eye care outside of an IDN.
• To evaluate the impact of this 'leakage' on coordinated diabetes management.
• To assess the communication of eye examination results back to PCPs.

Main Methods:

• Analysis of claims data for 1,139 patients aged 18-75 with diabetes within an IDN and accountable care organization (ACO).
• Logistic regression used to analyze demographic and biometric factors associated with out-of-network eye examinations.
• Comparison of glycemic control, complication rates, and communication of results between in-network and out-of-network eye care.

Main Results:

• 37% of patients completed eye examinations out-of-network.
• Out-of-network care was associated with poorer glycemic control (A1c > 9.0%) and fewer documented complications, including diabetic retinopathy.
• Communication of eye exam results to PCPs was significantly lower for out-of-network care (74%) compared to in-network (100%).

Conclusions:

• Ophthalmologists outside IDNs must improve communication of eye exam findings.
• Enhanced communication is particularly important for patients with poorly controlled diabetes and those at risk of complications.
• Addressing out-of-network leakage can improve diabetes care coordination and patient outcomes.
