BACKGROUND: @entity2688 has many clinical mimickers (pseudocellulitis), which leads to frequent misdiagnosis. OBJECTIVE: To create a model for predicting the likelihood of @entity1746 . METHODS: A cross-sectional review was performed of all @entity1 admitted with a diagnosis of @entity1746 through the emergency department at a large hospital between 2010 and 2012. @entity1 discharged with diagnosis of @entity2688 were categorized as having @entity2688 , while those given an alternative diagnosis were considered to have pseudocellulitis. Bivariate associations between predictor variables and final diagnosis were assessed to develop a 4-variable model. RESULTS: In total, 79 (30.5%) of 259 @entity1 were misdiagnosed with @entity1746 . Of the variables associated with true @entity2688 , the 4 in the final model were asymmetry (unilateral involvement), @entity491 (white blood cell count >= 10,000/uL), @entity591 (heart rate >= 90 bpm), and age >= 70  years. We converted these variables into a points system to create the ALT-70 @entity2688 score as follows: Asymmetry (3 points), @entity491 (1 point), @entity591 (1 point), and age >= 70 (2 points). With this score, 0-2 points indicate >= 83.3% likelihood of pseudocellulitis, and >= 5 points indicate >= 82.2% likelihood of true @entity2688 . LIMITATIONS: Prospective validation of this model is needed before widespread clinical use. CONCLUSION: Asymmetry, @entity491 , @entity591 , and age >= 70 are predictive of @entity1746 . This model might facilitate more accurate diagnosis and improve @entity1 care.
