Online Supplement Impact of Relative Contraindications to Home Management in Emergency Department Patients with Low-Risk Pulmonary Embolism David R. Vinson, Carrieann E. Drenten, Jie Huang, J. Eileen Morley, Megan L. Anderson, Mary E. Reed, Daniel K. Nishijima, and Vincent Liu; on behalf of the KP CREST Network Table E1. The Pulmonary Embolism Severity Index Predictors Points* Demographic Characteristics Age + 1 per year Male sex + 10 Comorbid Illness Cancer (active or history of) + 30 Heart Failure (systolic or diastolic) + 10 Chronic Lung Disease (includes asthma) + 10 Clinical Findings Pulse 110/min beats per min + 20 Systolic blood pressure <100 mmhg + 30 Respiratory rate 30 breaths per min + 20 Temperature <36 C + 20 Altered mental status + 60 Arterial oxygen saturation <90% + 20 * A total point score for a given patient is obtained by summing the patient's age in years and the points for each applicable characteristic. Point scores correspond with the following classes that estimate escalating risks of 30-day mortality: 65 class I, very low risk; 66-85 class II, low risk; 86-105 class III, intermediate risk; 106-125 class IV, high risk; >125 class V, very high risk. The worst vital signs are used Acute or pre-existing disorientation, lethargy, stupor, or coma With or without supplemental oxygenation
