Cost-minimization analysis of drugs used for empirical treatment of urinary tract infection in a tertiary care hospital

Background: Urinary tract infections (UTIs) are one of the commonly encountered infections and a large number of drugs are indicated in UTI ranging from oral conventional drugs to most advanced injectable drugs. Cost-minimization analysis (CMA) is employed to project the least costly drug when two treatments are shown to be therapeutic equivalents. Aims and Objectives: This study aims to perform a CMA at a tertiary care center to determine the least expensive drug for UTI and to project a cheapest alternative from available options based on the results of CMA. Materials and Methods: This was a cross-sectional study conducted over duration of 3 months in the clinical departments on patients diagnosed to have UTI and prescribed empirical antimicrobial treatment. The approval of Institutional Ethics Committee was sought before beginning the study. Pattern of drug prescription and average cost incurred in the treatment of patients with empirical antimicrobial therapy was calculated. CMA included the projection of the least expensive drug based on average cost incurred per patient in outpatients and inpatients respectively. Results: A total of 59 patients of UTI given empirical treatment were included in the study. Fluoroquinolones and cephalosporins were commonly used drugs for empirical treatment of UTI. Nitrofurantoin (average cost of 11–14 Rs. per patient) can be projected as the cheapest drug for empirical treatment of UTI on outpatient basis as well as a drug to supplement injectables in indoor patients. Injectable ciprofloxacin can be projected as the most inexpensive alternative for empirical treatment of UTI in patients of the inpatient department. Conclusion: Nitrofurantoin for oral treatment and ciprofloxacin in injectable form are cheapest among available alternatives for empirical treatment of UTI. To prevent treatment failures and increase in cost of treatment, correlation of results of CMA with local antimicrobial sensitivity pattern is important.

RESUMEN Introducción: Las infecciones de las úlceras del pie diabético son comunes, complejas, de alto costo y constituyen la principal causa de amputación no traumática de las extremidades inferiores. Objetivo: Identificar los microorganismos aislados para estimar tanto la sensibilidad a los antibióticos como la coincidencia entre el tratamiento empírico y los resultados microbiológicos en pacientes con úlceras del pie diabético. Métodos: Se realizó una investigación descriptiva-retrospectiva. La población de estudio estuvo constituida por 210 pacientes ingresados en el Hospital Universitario Clínico Quirúrgico "Comandante Faustino Pérez Hernández" de Matanzas entre junio de 2017 y junio de 2020. Las variables de salida fueron la frecuencia y el tipo de germen, la cantidad de gérmenes por úlcera, la sensibilidad para cada tipo de antibiótico, y el porcentaje de coincidencia entre el tratamiento empírico y el resultado microbiológico. Resultados: Se identificaron 259 gérmenes y se observaron 1,23 gérmenes por úlcera. El 62,5 por ciento de los gérmenes encontrados fueron Gram negativos, pero el germen más representado fue el Staphylococcus aureus. El 58,8 por ciento de los Staphylococcus aureus se mostraron resistentes a la meticillin. La vancomicina y el linezolid resultaron efectivos en el 100 por ciento de los Gram positivos. La amikacina fue el antibiótico más efectivo para los Gram negativos. Se observó coincidencia entre el tratamiento empírico y el resultado del antibiograma en el 27,6 por ciento de los pacientes. Conclusiones: Resulta necesario un apropiado diagnóstico microbiológico de las úlceras del pie diabético para identificar los gérmenes presentes en las lesiones y diseñar algoritmos de terapia antimicrobiana adecuados(AU)

ABSTRACT Introduction: Diabetic foot ulcer infections are common, complex, high cost and are the leading cause of non-traumatic lower extremity amputation. Objective: To identify the microorganisms isolated to estimate both the sensitivity to antibiotics and the coincidence between empirical treatment and microbiological results in patients with diabetic foot ulcers. Methods: A descriptive-retrospective investigation was performed. The study population consisted of 210 patients admitted to the University Hospital "Comandante Faustino Pérez Hernández" of Matanzas between June 2017 and June 2020. The output variables were the frequency and type of germ, the number of germs per ulcer, the sensitivity for each type of antibiotic, and the percentage of coincidence between the empirical treatment and the microbiological result. Results: A total of 259 germs were identified and 1.23 germs per ulcer were observed. The 62.5 percent of the germs found were Gram negative, but the most represented germ was Staphylococcus aureus. Of the Staphylococcus aureus, 58.8 percentwere resistant to methicillin. Vancomycin and linezolid were effective in 100 percent of Gram positives. Amikacin was the most effective antibiotic for Gram-negatives. Agreement between empirical treatment and antibiogram result was observed in 27.6 percent of patients. Conclusions: An appropriate microbiological diagnosis of diabetic foot ulcers is necessary to identify the germs present in the lesions and to design adequate antimicrobial therapy algorithms(AU)

Factores de riesgo asociados a infecciones del tracto urinario por gérmenes productores de betalactamasas de espectro extendido / Risk factors associated with urinary tract infections by spectrum betalactamase producing germs extended

El tratamiento de las infecciones del tracto urinario requiere la constante actualización de la susceptibilidad in vitro de los gérmenes de la zona o institución que permita orientar la elección apropiada del tratamiento empírico. Objetivo: Identificar los factores de riesgo asociados a infecciones del tracto urinario por gérmenes productores de BLEE en pacientes hospitalizados en el Hospital Militar "Dr. Carlos Arvelo" con diagnóstico de infección del tracto urinario durante el periodo enero de 2015 y diciembre de 2019. Método: estudio retrospectivo, corte transversal, casos y controles. Tratamiento estadístico: Se calculó la razón de probabilidades de los factores de riesgo previamente establecidos. Los factores que demuestren asociación significativa en el análisis univariable serán incluidos en el modelo de regresión logística a fin de determinar los predictores independientes de infección por gérmenes productores BLEE. Resultados: Se evaluaron 283 pacientes, 161 con fenotipo de BLEE y 122 no BLEE. La edad mayor a 65 años (p =0,001; OR 1,059), infección del tracto urinario recurrente (p <0,001; OR 3,689), uso de antibióticos en los último 3 meses (p <0,001; OR 6,921), y sondaje vesical permanente mayor a 30 días (p <0,001; OR 6,801) fueron predictores independientes de ITU por bacterias productoras de BLEE. Conclusiones: Los factores de riesgo identificados en nuestro estudio ayudarán a guiar el reconocimiento de pacientes con alto riesgo de infección por estos organismos. Estos resultados sugieren la necesidad de revisión de los esquemas terapéuticos empíricos locales en el tratamiento de infecciones del tracto urinario, basándose en el riesgo de cada paciente(AU)

Urinary tract infections are an important cause of disease, its treatment requires the permanent update of in vitro antimicrobial susceptibility of the major germs of the institution to allow the appropriate choice of empirical treatment; Objective: To identify the risk factors associated with urinary tract infections caused by extended-spectrum beta-lactamases-producing germs in patients admitted at the Hospital Militar "Dr. Carlos Arvelo" with urinary tract infections between the january 2015 and december 2019. Methods: this is a retrospective study of a crosssectional cohort of cases and controls. Statistical Analysis: We also calculated adjusted odds ratios and 95% confidence intervals for target risk factors. Risk factors with significant association to ESBLs in the univariate analysis were included in a logistic regression model in order to determine independent forecasters of infections by ESBL-producing organisms. Results: Two hundred and eighty three patients were assessed: 161 with a phenotype of ESBL and 122 without ESBL. Ages over 65 years old (p =0,001; OR 1,059), regular urinary tract infection (p <0,001; OR 3,689), use of antibiotics in the last 3 months (p <0,001; OR 6,921), and permanent bladder catheterization for more than 30 days (p <0,001; OR 6,801) were independent forecasters of UTIs by ESBL-producing bacteria. Conclusions: the risk factors identified in our study will help guide the recognition of patients at high risk of infection by these organisms. These results suggest the need to review local empirical therapeutic schemes in the management of urinary tract infections, based on the odds of each patient of acquiring these bacteria(AU)

Distribution of bacteria of wound secretion and drug susceptibility analysis in infected patients from Department of Hand Surgery / 吉林大学学报(医学版)

Objective: To analyze the results of bacteria distribution of wound secretion and the drug susceptibility test of the infected patients from Department of Hand Surgery, and to provide the evidence for antibiotic selection in the infected patients in early stage of treatment. Methods: The clincal data of hospitalized patients from Department of Hand Surgery were collected. The patients were divided into three groups according to the wound conditions. The patients in Group 1 who had no wound while being in hospital were infected after operation; the patients in Group 2 had the contaminated wound but no infection while being in hospital; the patients in Group 3 had definite infection while being in hospital. The results of bacterium culture of wound secretion and drug susceptibility test of the patients in three groups were analyzed. Results: The clinical data of 297 patients were obtained, including 17 patients from Group 1, 201 patients from Group 2, and 79 patients from Group 3. A total of 406 strains of 54 species of bacteria were isolated from 297 patients, including 178 strains (43. 84%, 178/406) gram-positive bacteria and 228 strains (56. 2%, 228/406) gram-negative bacteria. The four most common strains were Staphylococcus aureus (15.8%, 64/406), Staphylococcus epidermidis (14.0%, 57/406), Enterobacter cloacae (10.3%, 42/406), and Serratia marcescens (9.9%, 40/406). The results of drug susceptibility test showed that the detection rates of methicillin-resistant staphylococcus aureus (MRSA) and staphylococcus epidermidis were 9. 4% (6/64) and 72. 0% (46/64), respectively. There were no vancomycin-resistant, linezolidresistant, and tigecycline-resistant positive strains among Staphylococcus susceptibility; and there were no the carbapenem-resistant positive strains among Enterobacter cloacae and Serratia marcescens. The susceptibility rate of Enterobacter cloacae to ceftriaxone was 83. 3% (35/42), and its susceptibility to ceftazidime was 90. 5% (38/42). The susceptibility rate of Serratia marcescens to ceftriaxone was 100.0% (40/40), and its susceptibility to ceftazidime was 97.5% (39/40). Conclusion: The first generation of cephalosporin and penicillinase-stabilized penicillin can be used as the preferred empirical antibiotics for the infected patients from Deparment of Hand Surgery in our hospital. The third and fourth generation cephalosporins and quinolones antibiotics can be used as the preferred antibiotics for the infected patients with open trauma as well as the possibility of G- bacillus infection.

Increasing Incidence of Listeriosis and Infection-associated Clinical Outcomes

BACKGROUND: Listeriosis caused by Listeria monocytogenes has a high case-fatality rate (CFR) of approximately 20% to 30%. An increasing incidence of listeriosis has been reported in many countries recently. We investigated the annual incidence, clinical characteristics, and outcomes of listeriosis at three different hospitals in Korea and evaluated the effects of appropriate empiric antimicrobial treatments on patient outcomes. METHODS: We retrospectively collected the data of all culture-positive cases of human listeriosis from three hospitals of different sizes in Korea during 2006–2016 and calculated the annual number of cases and incidence per 100,000 admissions. RESULTS: A total of 58 patients with L. monocytogenes were included in this study. The incidence of listeriosis was significantly higher in 2013–2016 than in 2006–2012 (RR 3.1; 95% CI 1.79–5.36; P < 0.001), mainly because of an increase in patients over 60 years of age (RR 3.69; 95% CI 1.70–8.02; P < 0.001). Multivariate analysis showed that healthcare-associated infection (adjusted OR, 12.15; 95% CI, 2.56–86.01; P=0.004) and empirical treatment with first-line antimicrobial agents (adjusted OR, 0.08; 95% CI, 0.00–0.63; P=0.044) were associated with CFR. CONCLUSIONS: Healthcare-associated infections caused by L. monocytogenes are associated with high CFR. Adequate initial empirical treatments could reduce CFR, suggesting that careful consideration of an empirical antimicrobial regimen is warranted for elderly or immunocompromised patients admitted to the hospital.

Community acquired urinary tract infection in pediatric age-group with changing trends of antibiotic resistance pattern over 3 years: a clinicoepidemiological study.

Background: Assessment of the antimicrobial sensitivity pattern in urinary isolates of the children suffering from urinary tract infection (UTI) and evaluation of the recent trends of multi-drug resistance in the isolates. The aim was to find out the antibiotics sensitivity of the organisms isolated from the urine samples of pediatric age-group with emphasis on their resistance pattern. Methods: A clinico-epidemiological study comprising of 304 specimens of urine were collected among all the children with UTI below 12 years of age, attending pediatric outpatient department of a tertiary care teaching hospital in eastern India wet mount microscopy and semi quantitative culture were done to diagnose UTI. Organisms isolated were identified by standard biochemical tests, and antibiogram studies were done by standard Kirby-Bauer disc diffusion test statistical analysis, Microsoft excel and SPSS were used for analysis of data. Results: Aminoglycosides had wider sensitivity pattern toward most of the uropathogens whereas tetracyclines and co-amoxyclav in particular were resistant for most of the organisms. Among all the organisms, Pseudomonas and Enterococcus species showed higher resistance pattern toward the conventional antimicrobials. Conclusions: The changing trends in the anti-biograms of several Gram-positive and Gram-negative microorganisms in UTI demands reconsideration with respect to rational drug use in the pediatric age group.

Bacteriological features of infectious spondylodiscitis at Mohammed V Military Teaching Hospital of Rabat

To review the bacteriological features of infectious spondylodiscitis and provide recommendations for the initial therapy which remains empirical in our context. Retrospective study including patients diagnosed with spondylodiscitis over a period of 4 years (2006-2009) at the Rabat Military Teaching Hospital. During the study period, we analysed 30 cases: the mean age was 49.9 years and 21 cases (70%) were male. The patients were predominantly hospitalized in neurosurgery department (15/30) followed by rheumatology department (10/30). The site of infection was lumbar in 21 cases (21/30), dorsal in 7 cases (7/30). 26 cultures were positive of which 19 (19/26) were monomicrobial. Tuberculosis (TB) was implicated in 10 cases (10/30) including 4 cases in association with common organisms (Propionibacterium acnes, Staphylococcus aureus, Staphylococcus epidermidis, Corynebacterium species). Brucella melitensis was isolated in 1 case. Infections caused by pyogenic bacteria were isolated in 15 cases of which 12 (12/15) revealed simple organisms including Gram-positive cocci in 9 cases (9/12) with 3 cases of S. aureus and Gram-negative bacilli in 3 cases (3/12) with 2 cases of P. aeruginosa. Blood cultures carried out for 16 patients were positive in 7 cases. The anatomopathologic exams carried out for 20 patients found in 6 cases epithelioid granulomata and giants cells with caseous necrosis in total concordance with TB culture. TB is the most frequent cause of spondylodiscitis in Morocco. Our study found the same frequency for non-specific and specific germs. Empirical treatment must take into account S. aureus and M. tuberculosis.

El 78 por ciento de estos era de sexo femenino y el mayor número de consultas se dieron en personas con edades entre los 70 y 79 años (33.3 por ciento). El 52.9 por ciento de los casos necesitó solo un día de hospitalización, recibiendo tratamiento sistémico el 15,7 por ciento de los pacientes que presentaba complicaciones o reagudización del cuadro. Conclusiones: El porcentaje de hospitalizaciones por DA constituye el 5,5 por ciento del total de hospitalizaciones por patologías oculares, la cual se manifiesta mayormente en mujeres adultas mayores, con hospitalizaciones de un día y antibióticoterapia sistémica efectuada con cloxacilina.

Acute dacryocystitis is an inflammation of the lacrimal sac and nasolacrimal duct, mostly secondary infection process, or senile duct stenosis, trauma, tumors, sinusitis, or chronic conjunctivitis and canaliculitis. The age groups most affected are infants and elderly, especially women. Infectious agents most commonly involved are Staphylococcus aureus and Streptococcus beta-hemolytic. There are no epidemiological studies or history of national and local causative of this condition. Objectives: To determine the frequency of hospitalization, the age distribution by sex and prevalence of this disease, know the length of hospital employee and the treatment received by patients Methodology: The data required for the study was obtained from a review of clinical records of patients Results. A total of 1870 hospitalizations eye made between June and Oecember 2007, 102 were for dacryocystitis (55 percent). 78 percent of patients were female and the largest number of inquiries occurred in patients aged 70 to 79 years (33.3 percent) The 52.9 percent of cases needed only one day of hospitalization, receiving systemic treatment for 15.7 percent of patients had complications or exacerbation of the clinical, being the drug of choice, cloxacillin. Conclusions: The incidence of hospitalizations for acute dacryocystitis is 5.5 percent of total hospitalizations for ocular pathologies. Oacryocystitis occurs mostly in older adults, whose age ranges are between 60 and 89 years, mostly female. The hospitalization time required is not more than one day to prepare for surgery, for the treatment of infectious event is performed as an outpatient. Systemic antibiotic therapy conducted in patients who show no response to empiric therapy is cloxacillin.

Comparison of in vitro activities of ceftazidime, piperacillin-tazobactam, and cefoperazone-sulbactam, and the implication on empirical therapy in patients with cancer.

Background: Infection is a common cause of morbidity and mortality in cancer patients. In most of these cases empirical treatment is provided because the focus of infection is not identified. Empiric antibiotics provided to these patients are based on isolates, sensitivity, and on guidelines. Here we have compared three antibiotics recommended as empirical treatment by the Infectious Disease Society of America (IDSA). Aims: To compare the three antibiotic sensitivities for gram negative isolates at our institute. Objective: To choose the optimal antibiotic as the empirical treatment for cancer patients developing infections. Materials and Methods: We collected the data on isolates and antibiotic sensitivity patterns of isolates for ceftazidime, piperacillin + tazobactum, and cefoperazone from the medical oncology department. We subsequently compared the sensitivity of these three antibiotics. Statistical Methods: The isolates were mapped using the WHONET 5.4 software. The analysis was conducted using SPSS 15.0 for Windows. McNemar Chi-square test was used to compare the sensitivity percentages between any two antibiotics. The agreement between the antibiotic and the gold standard was calculated using the Kappa statistic. Two tailed p values were reported. Results: The results showed that there was a difference among sensitivities for these antibiotics. It appears that the sensitivity of ceftazidime was inferior to the two other antibiotics. Also cefoperazone has better sensitivity as compared to piperacillin + tazobactum. Conclusion: In spite of these three antibiotics being recommended by IDSA our data suggest that it should not be followed blindly and local sensitivity data is important for formulating institutional guidelines for using antibiotics.
