Retrospective Real-World Evaluation of Outcomes in Patients with Skin and Soft Structure Infections Treated with Tedizolid in an Outpatient Setting

Abstract

Introduction: Outcomes data for patients who received tedizolid for acute bacterial skin and skin-structure infections (ABSSSIs) are scant. We provide a real-world analysis of economic and clinical outcomes following tedizolid use in the outpatient setting.

Methods: This retrospective study of adults with skin infections treated with tedizolid (index period: 1 July 2014-31 May 2016) used data from the Optum Research and Impact National Benchmark databases.

Results: Ninety-one patients received tedizolid for the treatment of skin infections (with complications, n = 18; without complications, n = 73). Some patients had > 1 complication and infection site. Among patients with complications, pre-index complications during the [index date - 30] through [index date + 1] period included osteomyelitis (44.4%), septicemia (44.4%), and prosthetic joint/device/graft infection (16.7%). For the [index date - 7] through [index date + 1] period, the infection site included abscesses (55.6%) and chronic ulcers (38.9%). Mean (standard deviation [SD]) days supplied for the index tedizolid claim was 6.8 (2.3) days. Healthcare resource utilization (HCRU) during the 30-day post-index period included ≥ 1 ambulatory visit (100.0%), ≥ 1 emergency department (ED) visit (16.7%), and ≥ 1 hospitalization (22.2%). Median 30-day post-index all-cause costs were $11,098 [lower quartile (Q₁), $5688; upper quartile (Q₃), $16,246; mean (SD), $14,637 ($11,435)]. Among patients without complications, the pre-index infection site from ([index date - 7] through [index date + 1]) included abscesses (60.3%), chronic ulcers (37.0%), and cellulitis (2.7%). Mean (SD) days supplied for the index tedizolid claim was 6.6 (2.5) days. Thirty-day post-index HCRU included ≥ 1 ambulatory visit (91.8%), ≥ 1 ED visit (17.8%), and ≥ 1 hospitalization (5.5%). Median 30-day post-index all-cause costs were $3230 (Q₁, $2345; Q₃, $6847; mean [SD], $6898 [$11,129]).

Conclusions: Patients treated with tedizolid in the outpatient setting experienced a short duration of therapy, low hospital admission, and modest post-index HCRU indicators, suggesting its utility for outpatient therapy of ABSSSIs.
