Background: Health insurance design can influence the extent to which clinical care is well-coordinated. Through alternative payment models, Medicare Advantage (MA) and Accountable Care Organizations (ACOs) have the potential to improve integration relative to traditional fee-for-service (FFS) Medicare. Objective: To characterize patient experiences of integrated care within Medicare and identify whether MA or ACO beneficiaries perceive greater integration than FFS beneficiaries. Design: Retrospective cross-sectional analysis of the 2015 Medicare Current Beneficiary Survey. Subjects: Nationally representative sample of 11,978 Medicare beneficiaries. Measures: Main outcomes included 8 previously derived domains of patient-perceived integrated care (PPIC), measured on a scale of 1–4. Results: The final sample was 55% female with a mean (SD) age of 71.1 (11.3). In unadjusted analyses, we observed considerable variation across PPIC domains in the full sample, but little variation across subsamples defined by coverage type within a given PPIC domain. In linear models adjusting for a rich set of patient characteristics, we observe no significant benefits of ACOs nor MA relative to FFS, a finding which is robust to alternative specifications and adjustment for multiple comparisons. We similarly observed no benefits in subgroup analyses restricted to states with relatively high market penetration of ACOs or MA. Conclusions: Despite characteristics of ACOs and MA that theoretically promote integrated care, we find that PPIC is largely similar across coverage types in Medicare.

Background: Pregnant patients with pre-existing diabetes mellitus (DM) are at increased risk for development or progression of existing diabetic retinopathy (DR). A quality improvement project was initiated to improve DR screening during pregnancy at a safety net hospital. This article highlights the utility and generalizability of our telemedicine-based screening model. Materials and Methods: In April 2018, we implemented a photographic retinal screening system in the Maternal Fetal Medicine (MFM) clinic at Santa Clara Valley Medical Center in San Jose, CA. The system is intended to screen all pregnant patients with pre-existing diabetes (type 1 and 2). Retinal images are automatically uploaded to a secure server and interpreted by a retina specialist (C.K.P.). Results: A total of 71 pregnant patients with pre-existing DM were seen in the MFM clinic during the study period. Sixty-six of 71 patients (93.0%) were screened compared with 69.1% in the year prior. Of the 64 patients screened with readable images 11 (17.2%) had DR, whereas 53 did not. Forty-nine of the 64 (74.2%) patients screened underwent screening using the new nonmydriatic system in the MFM clinic. Only 7 out of 47 (14.9%) patients with readable images in the MFM clinic required referral to the ophthalmology clinic. Conclusion: Our model for DR screening in pregnant patients in safety net hospitals is effective in improving screening rates and expediting evaluation and treatment for those in need. This system can prevent irreversible vision loss in pregnant patients and provides an effective framework for ophthalmic care in a safety net hospital system.
