Outpatient Parenteral Antibiotic Treatment for Infective Endocarditis: A Prospective Cohort Study From the GAMES Cohort.

BACKGROUND: Outpatient parenteral antibiotic treatment (OPAT) has proven efficacious for treating infective endocarditis (IE). However, the 2001 Infectious Diseases Society of America (IDSA) criteria for OPAT in IE are very restrictive. We aimed to compare the outcomes of OPAT with those of hospital-based antibiotic treatment (HBAT). METHODS: Retrospective analysis of data from a multicenter, prospective cohort study of 2000 consecutive IE patients in 25 Spanish hospitals (2008-2012) was performed. RESULTS: A total of 429 patients (21.5%) received OPAT, and only 21.7% fulfilled IDSA criteria. Males accounted for 70.5%, median age was 68 years (interquartile range [IQR], 56-76), and 57% had native-valve IE. The most frequent causal microorganisms were viridans group streptococci (18.6%), Staphylococcus aureus (15.6%), and coagulase-negative staphylococci (14.5%). Median length of antibiotic treatment was 42 days (IQR, 32-54), and 44% of patients underwent cardiac surgery. One-year mortality was 8% (42% for HBAT; P < .001), 1.4% of patients relapsed, and 10.9% were readmitted during the first 3 months after discharge (no significant differences compared with HBAT). Charlson score (odds ratio [OR], 1.21; 95% confidence interval [CI], 1.04-1.42; P = .01) and cardiac surgery (OR, 0.24; 95% CI, .09-.63; P = .04) were associated with 1-year mortality, whereas aortic valve involvement (OR, 0.47; 95% CI, .22-.98; P = .007) was the only predictor of 1-year readmission. Failing to fulfill IDSA criteria was not a risk factor for mortality or readmission. CONCLUSIONS: OPAT provided excellent results despite the use of broader criteria than those recommended by IDSA. OPAT criteria should therefore be expanded.

Effectiveness and safety of ertapenem used in hospital-at-home units: data from Spanish Outpatient Parenteral Antimicrobial Therapy Registry.

AIM: To evaluate the effectiveness and safety of ertapenem in patients hospitalized at home. PATIENTS & METHODS: Retrospective analysis of data from Spanish Outpatient Parenteral Antimicrobial Therapy (OPAT) registry. RESULTS: Data from 1428 patients (median age 70 years; 5.4% institutionalized) and 1547 infectious processes (24% self-administration) were analyzed. Clinical cure or improvement was achieved in 93.8% of cases. Rate of related readmissions was 4.2%, of clinically important complications -3.9%, and of adverse drug reactions -3.2%. High comorbidity burden, contagion in nursing home and certain types of infection were associated with worse prognosis. Self-administration was effective and safe, except in case of nursing home-acquired infections. CONCLUSION: Ertapenem OPAT was effective and safe. Caregivers in nursing homes should be better trained in OPAT-related procedures.

Efficiency of a self-administered outpatient parenteral antimicrobial therapy (s-opat) for infective endocarditis within the context of a shortened hospital admission based on hospital at home program.

OBJECTIVE: This study aimed to evaluate the efficiency of treatment of infectious endocarditis (IE) via Self-administered Outpatient Parenteral Antimicrobial Therapy (S-OPAT) supported by a shortening hospital admission program in a hospitalization-at-home unit (HAH), including a short review of the literature. METHODS: Ambispective cohort study of 57 episodes of IE in 54 patients treated in an HAH unit between 1988 and 2014 who receive S-OPAT after prior intra-hospital clinical stabilization. Characteristics of each episode of IE, safety and efficiency of the care model, were analyzed. RESULTS: Forty-three (76%) patients were males with a median age of 61 years (SD = 16.5). A total of 37 (65%) episodes affected the native valve (42% the aortic valve). In 75%, a micro-organism was isolated, of which 88% were Gram-positive bacteria. No deaths occurred during HAH program, clinical complications appeared in 30% of episodes, only 6 patients were re-admitted to hospital although no patient died. In the 12 months' follow-up 3 cases had a recurrence. The average cost of a day stay in HAH was €174 while in traditional cardiology hospitalization was €1100. The total average cost of treatment of each episode of IE managed entirely in hospital was calculated as €54,723. Application of the S-OPAT model based on HAH meant a cost reduction of 32.72%. CONCLUSIONS: In suitably selected patients, treatment of IE based on S-OPAT supported by a shortening hospital admission care program by means of referral to a HAH unit is a safe and efficient care model which entails a significant cost saving for the public healthcare system.

Safety and efficacy of daptomycin in outpatient parenteral antimicrobial therapy: a prospective and multicenter cohort study (DAPTODOM trial).

BACKGROUND: Daptomycin is an optimal choice for outpatient parenteral antibiotic therapy (OPAT) because of its safety, once-daily administration and its activity against Gram-positive bacteria. Although daptomycin is increasingly being used in OPAT, limited information about its safety in this scenario is available. METHODS: We performed a prospective multicentre pilot study to evaluate the safety of daptomycin in outpatients with proved or suspected Gram-positive infections (DAPTODOM). The primary objective was to evaluate the safety and the secondary objective to evaluate the efficacy in OPAT. We also looked at the development of daptomycin resistance in those cases with microbiological failure. RESULTS: We included 54 patients from 12 Spanish hospitals, 67% male with a mean age of 67.1 years. Most patients (87%) had chronic underlying diseases. The main reason for inclusion was skin and soft-tissue infections in 52%, followed by bacteremia or endocarditis in 34%. Staphylococcus aureus accounted for 44% of the isolates (24% were methicillin-resistant), coagulase-negative staphylococci 15% and enterococci 7%. Two patients (4%) had to be readmitted because of complications; only one patient had an adverse effect related to daptomycin (increase in serum creatine kinase levels), which disappeared after discontinuation (2%). At the end of follow-up, 96% of patients had good outcome and only 4% of patients did not have a clinical or microbiological cure. The use of a 2-minute bolus in 18 cases was not associated with adverse effects. CONCLUSIONS: Daptomycin was safe and efficacious in outpatients with Gram-positive bacterial infections and can be administered in 2-minute bolus infusion.

Papel de la bacteriobilia en las complicaciones postoperatorias / Role of bacteriobilia in postoperative complications

Introducción. Actualmente existe controversia respecto al impacto de la positividad de cultivos biliares en la tasa de morbilidad y mortalidad, y en la incidencia de readmisiones en pacientes con enfermedad biliar. El objetivo de este estudio fue evaluar el papel de la bacteriobilia en las infecciones postoperatorias, la mortalidad o el reingreso hospitalario en estos pacientes. Métodos. La información se obtuvo a partir de los cultivos de vía biliar de los pacientes intervenidos en el Hospital Universitario Marqués de Valdecilla (Santander, España) entre enero y diciembre de 2011. Se analizaron los datos clínicos, epidemiológicos y microbiológicos. Los pacientes fueron seguidos durante dos años. Resultados. Se incluyeron 152 pacientes (65% varones). La media de edad fue de 67 años (DE: 15 años). Los diagnósticos más frecuentes fueron colecistitis aguda (79%) y colangitis (8%). Se realizó colecistectomía laparoscópica en el 42% de los pacientes, colecistectomía abierta en el 45% y colecistostomía percutánea en el 8%. La bacteriobilia estaba presente en 83 pacientes (55%). Los microorganismos más frecuentemente aislados fueron Escherichia coli (31%), Enterococcus faecium (13%) y Klebsiella pneumoniae (13%). Los antibióticos iniciales fueron carbapenémicos en 62 pacientes (44%) y piperacilina-tazobactam en 28 pacientes (18%). Hubo 39 infecciones postoperatorias (26%) y 17 pacientes fallecieron durante el ingreso (11%). Se registraron 21 reingresos (14%). La bacteriobilia no fue un predictor estadísticamente significativo de complicaciones o reingreso hospitalario. Conclusiones. Los cultivos biliares intraoperatorios permitieron orientar la terapia antimicrobiana empírica y el tratamiento antibiótico apropiado; sin embargo no hubo correlación entre la bacteriobilia y las infecciones posoperatorias, la duración del ingreso, la mortalidad o los reingresos (AU)

Introduction. At present there is a controversy regarding the impact of positive bile cultures on morbidity and mortality rates, and on the incidence of readmissions in patients with biliar disease. The aim of this study was to evaluate the role of bacteriobilia in postoperatory infections, mortality or readmissions in these patients. Methods. The information was obtained from all patients with bile cultures admitted to Hospital Universitario Marqués de Valdecilla (Santander, Spain) from January to December 2011. Clinical, epidemiological and microbiological data and laboratory findings were analyzed. The patients were followed for two years. Results. One hundred and fifty-two patients (65% men) were included. Mean age was 67 years (SD= 15 years). The most frequent diagnoses were acute cholecystitis (79%) and cholangitis (8%). Laparoscopic cholecystectomy was performed in 42% of patients, open cholecystectomy in 45% and percutaneous cholecystostomy in 8%. Bacteriobilia was present in 83 patients (55%). The most frecuent microorganisms isolated were Escherichia coli (31%), Enterococcus faecium (13%) and Klebsiella pneumoniae (13%). The initial antimicrobial agent was a carbapenem in 62 patients (44%) and piperacillin-tazobactam in 28 (18%). There were 39 postoperative infections (26%), 21 readmissions (14%) and 17 patients died during admission (11%). The presence of microorganisms in bile cultures was not a statistically significant predictor of neither complications nor readmissions. Conclusions. Intra-operative bile cultures would allow guide early appropriate antibiotic treatment use in case of infection, or empiric antimicrobial therapy, however there was no correlation between bacteriobilia and postoperative infections, length of stay, mortality or readmissions (AU)

Self-administered outpatient parenteral antimicrobial therapy (S-OPAT) for infective endocarditis: a safe and effective model.

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 4.8 weeks; 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.

Trend in hip fracture epidemiology over a 14-year period in a Spanish population.

Spain lacks detailed data on hip fracture trends despite being the country with the greatest increase in the pensioner-to-provider ratio in Europe. We reproduced a study on hip fracture incidence in a region of northern Spain (Cantabria) carried out 14 years ago to determine whether a secular trend to change is taking place. If such a trend could be found, our objective was to determine whether the effect is solely due to ageing or whether additional variables are involved. We assessed the incidence of hip fracture in patients aged > or =50 years through clinical records from Emergency Units and Orthopedic Surgical Units of all hospitals in the region of Cantabria in 1988 and 2002. A total of 318 new cases of hip fracture were recorded in 1988 and 490 in 2002 (54% increase; p<0.001). No significant changes were noticed following an adjustment for age. Women accounted for the increase in crude hip fracture incidence [246 women and 72 men suffered a hip fracture in 1988 compared to 404 women and 86 men in 2002 (64% increase in women and 19% increase in men; p<0.005 and not significant, respectively)]. The female:male ratio was 3.4 in 1988 versus 4.7 in 2002; following age-adjustment, no significant changes were found (1.8 in 1988 and 1.9 in 2002). The increase in crude hip fracture incidence was greater at cervical (versus trochanteric) sites. Patient residence, time of the year, site of fracture, kind of injury, previous contralateral hip fracture, length of stay, and peri-operative mortality did not differ significantly. In conclusion, a crude hip fracture incidence increase of about 50% in the northern Spanish region of Cantabria has taken place over the last 14 years. This effect does not persist after adjustments have been made for age. The crude rate increase occurred mainly at the expense of women, with a more noticeable rise in cervical fractures as opposed to trochanteric lesions.
