Cardiometabolic & kidneyCohort study
Health Plan-Based Atherosclerosis Imaging for Members with Diabetics
- pilot benefit comparing benefit utilizers to eligible nonutilizers
- matched cohort
- health plan claims data
Authors' conclusion
Utilization of QCCTA offered to an employed population with diabetes varies by demographics while increasing near-term health plan expenditure for cardiovascular care. Longer-term studies are warranted to evaluate QCCTA's impact in value-based care models on diabetic members' health outcomes and total health plan spend.
Study context
- Population
- Diabetic health plan members ≥40 years without prior myocardial infarction offered QCCTA as a pilot benefiteligible members identified of 38,079 health plan members, matched cohort of 169 utilizers and 169 nonutilizers · matched utilizers 169 · matched nonutilizers 169
- Participants
- 2,064 members
- Exposure
- Benefit utilizers were compared to eligible nonutilizers for incident cardiovascular episodes of care post-notification of eligibility.
- Utilizersn = 169
- nonutilizersn = 169

Further findings
| Outcome | Utilizers | nonutilizers | P value |
|---|---|---|---|
| glycated hemoglobin · glycemic control better in utilizers | 6.5% (range as printed 6.0%–7.3%) | 7.0% (range as printed 6.4%–7.7%) | P = 0.05 |
| 10-year atherosclerotic cardiovascular disease risk · lower in utilizers | 8.5% (range as printed 4.2%–15.8%) | 10.8% (range as printed 5.7%–20.3%) | P = 0.07 |
| incident cardiovascular episodes of care · median of 19 months' follow-up · more in utilizers · matched cohort | 1 (range as printed 1–3) | 1 (range as printed 1–1) | P < 0.0001 |
| incremental per-member per-month health plan expenditure for cardiovascular episodes of care · median of 19 months' follow-up · higher in utilizers · matched cohort | $19.04/month (range as printed 4.65–85.11) | $0/month (range as printed 0–0) | P < 0.0001 |
| incremental per-member per-month health plan expenditure for cardiovascular episodes of care · median of 19 months' follow-up · matched cohort | P = 0.78 |
- incremental per-member per-month health plan expenditure for cardiovascular episodes of care: similar after adjusting for baseline glycated hemoglobin and atherosclerotic cardiovascular disease risk score
