Infectious diseases specialty intervention is associated with decreased mortality and lower healthcare costs.

BACKGROUND: Previous studies, largely based on chart reviews with small sample sizes, have demonstrated that infectious diseases (ID) specialists positively impact patient outcomes. We investigated how ID specialists impact mortality, utilization, and costs using a large claims dataset. METHODS: We used administrative fee-for-service Medicare claims to identify beneficiaries hospitalized from 2008 to 2009 with at least 1 of 11 infections. There were 101 991 stays with and 170 336 stays without ID interventions. Cohorts were propensity score matched for patient demographics, comorbidities, and hospital characteristics. Regression models compared ID versus non-ID intervention and early versus late ID intervention. Risk-adjusted outcomes included hospital and intensive care unit (ICU) length of stay (LOS), mortality, readmissions, hospital charges, and Medicare payments. RESULTS: The ID intervention cohort demonstrated significantly lower mortality (odds ratio [OR], 0.87; 95% confidence interval [CI], .83 to .91) and readmissions (OR, 0.96; 95% CI, .93 to .99) than the non-ID intervention cohort. Medicare charges and payments were not significantly different; the ID intervention cohort ICU LOS was 3.7% shorter (95% CI, -5.5% to -1.9%). Patients receiving ID intervention within 2 days of admission had significantly lower 30-day mortality and readmission, hospital and ICU length of stay, and Medicare charges and payments compared with patients receiving later ID interventions. CONCLUSIONS: ID interventions are associated with improved patient outcomes. Early ID interventions are also associated with reduced costs for Medicare beneficiaries with select infections.

El infectológo y su labor en el hospital: 10 años de gestión, 2000-2009 / The infectious disease and its work in the hospital: 10 years of management, 2000-2009

El infectológo es de gran importancia en los hospitales; realiza funciones en atención ambulatoria, hospitalización, control de infecciones hospitalarias, docencia, investigación, asesoria en epidemias y pandemias entre otras. Precisar el cumplimiento de las funciones del infectológo, investigando la carga laboral y académica en HUC durante la última década. Se analizaron los registros de atención al paciente y programas académicos cumplidos desde el 1 de enero 2000 al 31 de diciembre 2009, calculando el número de pacientes evaluados en cada una de las actividades asistenciales y horas académicas. Se evaluaron 110 691 pacientes atendidos a través de los años. La distribución de las actividades correspondió a 72 521 (65 %) de atención en consultas ambulatorias (35 % pacientes viviendo con VIH y 30 % no VIH); 18 682 interconsultas de pacientes hospitalizados para control de antimicrobianos (17 %); 12 792 (12 %) cursos de tratamiento administrados en la sala de tratamiento ambulatorio (STA); 3 764 (3 %) egresos del SEIA y 2 932 personas atendidas por exposición de riesgo biológico. La actividad académica fue regular durante la década, cumpliendose los programas correspondientes. El número de horas empleadas en las revistas a los pacientes hospitalizados en el SEIA fue > 300/año. Seis miembros del servicio participaron en el programa del control de infecciones del HUC. Residentes y especialistas del SEIA cumplieron las funciones del infectológo en la última década;El mayor número de pacientes fue atendido de forma ambulatoria (consultas y la STA).

Hospital role of infectious diseases (ID) specialists is important. They participate in outpatient and inpatient care, hospital infection control, academic and research activities, and also pandemic and epidemic issues. This study's aim was to assess the number of activities, booth academic and im patients care, and fulfillment of ID physicians'roles at HUC during the last decade. Analysis of records for patient care and academic programs during January 1, 2000 to December 31, 2009. The number of patients clinically assessed and academic hours spent was calculated. During the decade, 110 691 patients were evaluated. There was a progessive increase of patients cared fir throughout they years. The activities distribution was as follows: 72 521 (65 %) outpatients (35 % HIV infected patients y % non HIV); 18 682 inpatients assessed following HUC policy on antibiotic control (17 %); 12 792 (12 %) courses of treatment administered at the outpatient treatment clinic (OTC); 3 764 (3 %) discharged patients fron SEIA y 2 932 people evaluated because of biologic risk exposition. Academic activities were fulfilled according to the fellowship program. Physicians dedicated more than 300 hour/year for inpatient rounds at SEIA. Six specialist form the ID Service also Were Members of HUC Infection Control Committee. Physicians at SEIA have accomplished the role of ID doctors during the last decade; most patients were evaluated outpatients and at OTC.
