  • Diabetic Retinopathy (DR) is the leading cause of blindness among working-aged adults affecting 9.6 million people in the U.S.*
  • DR prevalence rate is higher among
    • Ages 55-79 (28.66%)
    • Male (28.04%)
    • Black, non-Hispanic (33.81%) and Hispanic (28.04%)

Background

Percentage of 2021 US Resident Population With Diabetic Retinopathy (DR), by Stage and Age Group (CDC)

*CDC 2022, U.S. Department of Health and Human Services

  • DR is mostly asymptomatic
  • Routine screening is critical

for early diagnosis and timely

treatment to reduce the risk

of vision impairment, making

blindness preventable.

  • Diabetes care clinical guidelines include routine eye exams – Low DR screening rate (35-60%)
    • Individual level barriers (e.g., dilated eye exam, insurance, transportation)
    • Structural (e.g., lack of access to eye specialist)

DR Screening rate

  • Integrating point-of-care (POC) artificial intelligence (AI) technology for DR screenings in San Ysidro Health represents a unique and innovative opportunity to address unmet medical needs in diabetic eye care, enhancing existing our clinical practices.

Approach - Study Design

Practical, Robust Implementation and Sustainability Model (PRISM) Logic Model

12 of 42

Aim 1 (Co-Design)

To refine and operationalize a multi-component AI clinical intervention with physicians, clinical staff, and patients introducing autonomous DR screening integration in primary care.

13 of 42

    • 1-hour 7 virtual group interviews were conducted using brainwriting premortem (Gilmartin, 2019) to gather insights prior to implementing point-of-care AI-powered technology for screening diabetic retinopathy with: 
      • 12 San Ysidro Health patients
      • 11 Providers and clinic staff
    • $50 USD gift card
    • English and Spanish sessions (3/13 - 4/24/2024).

  • Interviewer guide included:
    • Possible reasons why this new screening program might fail
    • Potential solutions to address those failures.
  • Findings, solutions, and implementation plans from the interviews have been adopted for the research stage (R), some will be adopted following the research stage and during full SYH implementation (I), and others were deemed not necessary to address at either stage.

Aim 1 Co-Design Findings

Concerns Addressed Now

  1. Patient Hesitancy towards New Technology and AI
  2. Language Barriers and Cultural Sensitivity
  3. Staff Confusion and Role Delineation
  4. No-Show Rates and Late Arrivals
  5. Space and Exam Room Limitations
  6. Referral Process and Follow-Up Concerns
  7. Anxiety Over Receiving Negative or Complex Results
  8. Provider Bottleneck from Screening Delays
  9. Confusion About Comprehensive Yearly Eye Exams
  10. Patient Preference for Exams by a Provider
  11. Scheduling Challenges Due to Work and Transportation
  12. Clinic Wi-Fi and Power Concerns

Aim 1 Co-Design Findings

"They're so used to having provider engagement. You know…We saw it through the pandemic. We were able to overcome the telecommunication and the various modalities of contacting our patients but ultimately, they love provider engagement. So even though they're going to see their PCP, will they feel that loss of a specialized provider?"

“You’re depending on a robot, and as we can see, even with our phones, they can hack you, you know?”

"Does this consist of having a regular exam, and this is another exam on top of that?”

A total of 62 solutions were suggested by interviewees to address their perceived potential failures of the screening program.

"Artificial intelligence is a … label that's out in the communities. But most of our communities are kind of a little skeptical about it.“

Aim 1 Co-Design Findings

Shared Themes (Patients and Providers

"Artificial intelligence is a … label that's out in the communities. But most of our communities are kind of a little skeptical about it.“

"A lot of patients here are elderly patients and they [do] not really like AI … they're gonna be using a new technology, a new machine and everything, and it's like “What are you gonna do [to] me? I already have [an] eye doctor I don't want to go to."

  1. Patient Hesitancy towards New Technology and AI 

2. Patient Preference for Exams by a Provider

3. Power Failure

"They're so used to having provider engagement. You know…We saw it through the pandemic. We were able to overcome the telecommunication and the various modalities of contacting our patients but ultimately, they love provider engagement. So even though they're going to see their PCP, will they feel that loss of a specialized provider?"

“If it did go out [or] if the lights were out, it would[n’t] do anything"

17 of 42

Concerns Not Addressed Now

1. Lack of Clinical Decision-Making from the EyeArt Machine

  • Concerns: Lack of clinical decision-making.
  • Reason for not addressing: EyeArt is only designed to provide analysis on presence of DR that must be read and acted upon by the patient’s primary care physician or eye specialist.

 

2. Access to Retinal Specialists for Uninsured Patients

  • Concerns: Difficulties accessing follow-up specialty care.
  • Reason for not addressing: Current study patients will have the insurance necessary to receive the appropriate care.
  • Potential future solutions: Leverage community programs like Project Access, explore partnerships with retinal specialists, seek grants or funding for uninsured patients, Educate patients on insurance and available resources.

41 of 42

  • Evidence-based strategies adapted for the clinical environment.

  • Alignment to Patient Centered Medical Home (PCMH): enhancement of current patient care clinical workflows, quality improvement, and meaningful use of EHR.

  • Potential cost savings from reducing unnecessary visits to eye specialists and early diagnosis will reduce patients' lifetime treatment costs.

  • Findings from SYH’s research intervention will help identify best practices for scalability and capacity building, such as data privacy, algorithm accuracy, and ongoing evaluation to optimize the impact of AI/ML technology for diagnostic decision-making in real-world settings.
