Self-administered OPAT service for infective endocarditis


“In conclusion, the S-OPAT schedule of hospital-in-home is safe and efficacious in selected patients with IE” Pajarón et al (2015).


Pajarón, M., Fernández-Miera, M.F., Allende, I., Arnaiz, A.M., Gutiérrez-Cuadra, M., Cobo-Belaustegui, M., Armiñanzas, C., de Berrazueta, J.R., Fariñas, M.C. and Sanroma, P. (2015) Self-administered outpatient parenteral antimicrobial therapy (S-OPAT) for infective endocarditis: A safe and effective model. European Journal of Internal Medicine. January 14th. [epub ahead of print].


The safety and efficacy of treatment of infectious endocarditis (IE) was evaluated within a program of hospital-in-home (HIH) based on self-administered outpatient parenteral antimicrobial therapy (S-OPAT). IE episodes (n=48 in 45 patients; 71% middle-aged males) were recruited into the HIH program between 1998 and 2012. Following treatment stabilization at the hospital they returned home for HIH in which a physician and/or a nurse supervised the S-OPAT. Safety and efficacy were evaluated as mortality, re-occurrence, and unexpected re-admission to hospital. Of the episodes of IE, 83.3% had comorbidities with a mean score of 2.3 on the Charlson index and 1.5 on the Profund index; 60.4% had pre-existing valve disease (58.6% having had surgical intervention); 8.3% of patients had suffered a previous IE episode; 62.5% of all episodes affected a native valve; 45.8% being mitral; 70.8% of infection derived from the community. In 75% of the episodes there was micro-organism growth, of which 83.3% were Gram positive. Overall duration of antibiotic treatment was 4.8weeks; 60.4% of this time corresponding to HIH. Re-admission occurred in 12.5% of episodes of which 33.3% returned to HIH to complete the S-OPAT. No deaths occurred during HIH. One year after discharge, 2 patients had recurrence and 5 patients died, in 2 of whom previous IE as cause-of-death could not be excluded. In conclusion, the S-OPAT schedule of hospital-in-home is safe and efficacious in selected patients with IE.
