Recorded Adoption of SGLT2 Inhibitors from 2022 to 2025 Among Adults with an EHR-Defined HFrEF Phenotype at a Jordanian Public Hospital.

Background/

Objectives

Sodium-glucose cotransporter-2 inhibitors (SGLT2i) are foundational therapy for heart failure with reduced ejection fraction (HFrEF), irrespective of diabetes. We evaluated recorded SGLT2i adoption and diabetes-related differences among adults with an electronic health record (EHR)-defined HFrEF phenotype at a Jordanian public hospital.

Methods

This retrospective Hakeem cohort included 1750 adults. The frozen HFrEF phenotype was internally validated in an independent non-overlapping sample, and SGLT2i ascertainment was verified by complete-cohort medication review. Comparable annual analyses covered 2022-2025, when medication-source completeness exceeded 90%. Secondary analyses examined first recorded use after a 180-day lookback, concurrent four-class guideline-directed medical therapy (GDMT) in 2025, measured-eGFR threshold cohorts, and prespecified Firth regression among patients with type 2 diabetes (T2DM). Additional sensitivity analyses included a stable four-year cohort, a time-to-first-record analysis with explicit censoring, expanded model diagnostics with a time-to-event sensitivity analysis, and a strict directly documented-coverage GDMT analysis.

Results

Sixty-four patients had verified recorded SGLT2i use (3.66%; 95% CI 2.83-4.65). Use was 11.41% (64/561) with T2DM and 0% (0/1189; exact 95% CI 0-0.31) without diabetes. Annual prevalence increased from 0.15% in 2022 to 5.13% in 2025 (absolute increase 4.98 percentage points), while remaining 0% without diabetes. In the stable four-year cohort sensitivity analysis, prevalence similarly increased from 0.21% to 5.34%. In the verified 12-month fixed-horizon cohort, 27/1268 patients (2.13%) had a first recorded use within one year; the 322-day median was conditional on the 50 patients who eventually had a first post-index record and was not interpreted as a cohort-wide waiting time. Only 24/936 patients (2.56%) had all four foundational classes concurrently active in the primary 2025 analysis. The inverse nondialysis-CKD estimate was treated as exploratory because only four treated patients had nondialysis CKD.

Conclusions

Recorded adoption improved but remained low and strongly concentrated among patients with T2DM. Multicenter linkage of prescribing, eligibility, dispensing, persistence, and reimbursement data is needed to identify implementation mechanisms.
