ARTICLE HIGHLIGHTS
Research background
There is a paucity of data evaluating patients with dermatomyositis (DM) and polymyositis (PM) undergoing total hip arthroplasty (THA).
Research motivation
To compare and contrast the outcomes of patients undergoing THA with DM and PM vs a matched control without inflammatory arthropathies.
Research objectives
To elucidate whether patients with DM and PM have increased risk of complications and greater 90-d costs when undergoing THA compared to controls.
Research methods
A retrospective case control was performed based on the medicare data.
Research results
Patients with DM and PM had increased rates of pneumonia [odds ratio (OR) 1.45, P < 0.001] and pulmonary embolism (OR 1.46, P = 0.035) and decreased hematoma risks (OR 0.58, P = 0.00). 90-d costs were on average $1411 greater for those with idiopathic inflammatory myopathies (IIM) yet not significantly different (P = 0.034).
Research conclusions
Patients with IIM have an increased 90-d rate of pneumonia and pulmonary embolism concomitant with a decreased hematoma rate consistent with their pro-coagulatory state.
Research perspectives
It is important to evaluate deep vein thrombose prophylaxis and respiratory status in those undergoing THA with DM or PM.
