Infective endocarditis treated in a secondary hospital: epidemiological, clinical, microbiological characteristics and prognosis, with special reference to patients transferred to a third level hospital.

OBJECTIVE: To analyse the clinical and epidemiological characteristics and mortality-related factors of patients admitted to a secondary hospital with Infective Endocarditis (IE). METHODS: Observational study of a cohort of patients who have been diagnosed with IE in a secondary hospital and evaluated in accordance with a pre-established protocol. RESULTS: A total of 101 cases were evaluated (years 2000-2017), with an average age of 64 years and a male-to-female ratio of 2:1. 76% of the cases had an age-adjusted Charlson comorbidity index of >6, with 21% having had a dental procedure and 36% with a history of heart valve disease. The most common microorganism was methicillin-susceptible S. aureus (36%), with bacterial focus of unknown origin in 54%. The diagnostic delay time was 12 days in patients who were transferred, compared to 8 days in patients who were not transferred (p=0.07); the median surgery indication delay time was 5 days (IQR 13.5). The in-hospital mortality rate was 34.6% and the prognostic factors independently associated with mortality were: cerebrovascular events (OR 98.7%, 95% CI, 70.9-164.4); heart failure (OR 27.3, 95% CI, 10.2-149.1); and unsuitable antibiotic treatment (OR 7.2, 95% CI, 1.5-10.5). The mortality rate of the patients who were transferred and who therefore underwent surgery was 20% (5/25). CONCLUSIONS: The onset of cerebrovascular events, heart failure and unsuitable antibiotic treatment are independently and significantly associated with in-hospital mortality. The mortality rate was higher than the published average (35%); the diagnostic delay was greater in patients for whom surgery was indicated.

[Pneumonia in patients with SARS-CoV-2 infection: series of 17 cases in the region of Murcia]. / Neumonía neumocócica en pacientes con infección por SARS-CoV-2: serie de 17 casos en la Región de Murcia.

OBJECTIVE: Currently the prevalence of pneumococcal coinfection in patients with COVID-19 is unknown. In this work we present its clinical characteristics, evolution and treatment. METHODS: Retrospective data collection from August to October 2020 in two hospitals in the Murcia region. RESULTS: Eighteen patients had COVID-19 diagnosed by PCR and pneumococcal infection confirmed by antigenuria, which represented a prevalence of 2%. A total of 88% had radiological alterations upon admission (two patients had an X-ray within normality) and 29% had elevated procalcitonin. Mortality in our series was 12%. CONCLUSIONS: It could be reasonable to consider the start of antimicrobial therapy in those cases in which there is a moderate or high suspicion of bacterial coinfection, being essential the early suspension of antibiotic treatment if it is not confirmed.

[Design and implementation of an outpatient parenteral antimicrobial therapy program in primary care: the experience at a second level hospital]. / Design and implementation of an outpatient parenteral antimicrobial therapy program in primary care: the experience at a second level hospital.

OBJECTIVE: Outpatient parenteral antimicrobial therapy (OPAT) programs are a good assistance option in a wide variety of infectious diseases. Our aim was to design and implement an OPAT program in the area of influence of a second-level hospital, with no Home Hospitalization Service available, being necessary close collaboration between hospitalization and Primary Care teams, describe our cohort, analyse the antimicrobial treatment indicated and evaluate the prognostic and risk factors associated with readmission and mortality. METHODS: Prospective study cohorts of patients admitted to the OPAT programme, from 1 January 2012 to 31 May 2015. RESULTS: During the period of study a total of 98 episodes were recorded. The average age of the cohort was 66 years. The most frequent comorbidity was immunosuppression (33.67 %), with an overall average of Charlson index of 5.21 ± 3.09. The most common source of infection was respiratory (33.67 %). Microbiological isolation was achieved in fifty-eight patients (59.18 %) being Escherichia coli the most frequently isolated (25%). The average number of days of antibiotics administration at home was 10.42 ± 6.02 (SD), being carbapenems (43.48%) the more administered. Eighty-six patients (87.75%) completed the treatment successfully. Thirty-two patients (32.65%) were readmitted within 30 days after being discharged and seven patients (7.14%) died. A statistically significant association was only found in the readmission with variables: elderly patients (p=0.03), being carriers of Porth-a-Cath (p=0.04) and treatment termination related with infection (p<0.05). CONCLUSIONS: This is the first programme of OPAT administration not dependent on Home Hospitalization Service in Spain, which could allow to optimize the hospital and primary care resources available. Nevertheless this pilot study results are poor in terms of optimization of antibiotics choice, transition to oral administration, de-escalation and duration.
