Abstract

ALARCON, Álvaro; LAGOS, Isabel  and  FICA, Alberto. Gastos hospitalarios por neumonía neumocóccica invasora en adultos en un hospital general en ChileHospital charges by bacteremic pneumococcal pneumonia in adults in a general hospital. Rev. chil. infectol. [online]. 2016, vol.33, n.4, pp.389-394. ISSN 0716-1018.  http://dx.doi.org/10.4067/S0716-10182016000400003.

Pneumococcal infections are important for their morbidity and economic burden, but there is no economical data from adults patients in Chile. Aims. Estimate direct medical costs of bacteremic pneumococcal pneumonia among adult patients hospitalized in a general hospital and to evaluate the sensitivity of ICD 10 discharge codes to capture infections from this pathogen. Methods. Analysis of hospital charges by components in a group of patients admitted for bacteremic pneumococcal pneumonia, correction of values by inflation and conversion from CLP to US$. Results. Data were collected from 59 patients admitted during 2005-2010, mean age 71.9 years. Average hospital charges for those managed in general wards reached 2,756 US$, 8,978 US$ for those managed in critical care units (CCU) and 6,025 for the whole group. Charges were higher in CCU (p < 0.001), and patients managed in these units generated 78.3% of the whole cost (n = 31; 52.5% from total). The median cost in general wards was 1,558 US$, and 3,993 in CCU. Main components were bed occupancy (37.8% of charges), and medications (27.4%). There were no differences associated to age, comorbidities, severity scores or mortality. No single ICD discharge code involved a S. pneumoniae bacteremic case (0% sensitivity) and only 2 cases were coded as pneumococcal pneumonia (3.4%). Conclusions. Mean hospital charges (~6,000 US dollars) or median values (~2,400 US dollars) were high, underlying the economic impact of this condition. Costs were higher among patients managed in CCU. Recognition of bacteremic pneumococcal infections by ICD 10 discharge codes has a very low sensitivity.
