Early switch/early discharge opportunities for hospitalized patients with methicillin-resistant Staphylococcus aureus complicated skin and soft tissue infections in Brazil

ABSTRACT Background: Early antibiotic switch and early discharge protocols have not been widely studied in Latin America. Our objective was to describe real-world treatment patterns, resource use, and estimate opportunities for early switch from intravenous to oral antibiotics and early discharge for patients hospitalized with methicillin-resistant Staphylococcus aureus complicated skin and soft-tissue infections. Materials/methods: This retrospective medical chart review recruited 72 physicians from Brazil to collect data from patients hospitalized with documented methicillin-resistant Staphylococcus aureus complicated skin and soft tissue infections between May 2013 and May 2015, and discharged alive by June 2015. Data collected included clinical characteristics and outcomes, hospital length of stay, methicillin-resistant Staphylococcus aureus-targeted intravenous and oral antibiotic use, and early switch and early discharge eligibility using literature-based and expert-validated criteria. Results: A total of 199 patient charts were reviewed, of which 196 (98.5%) were prescribed methicillin-resistant Staphylococcus aureus -active therapy. Only four patients were switched from intravenous to oral antibiotics while hospitalized. The mean length of methicillin-resistant Staphylococcus aureus-active treatment was 14.7 (standard deviation, 10.1) days, with 14.6 (standard deviation, 10.1) total days of intravenous therapy. The mean length of hospital stay was 22.2 (standard deviation, 23.0) days. The most frequent initial methicillin-resistant Staphylococcus aureus-active therapies were intravenous vancomycin (58.2%), intravenous clindamycin (19.9%), and intravenous daptomycin (6.6%). Thirty-one patients (15.6%) were discharged with methicillin-resistant Staphylococcus aureus -active antibiotics of which 80.6% received oral antibiotics. Sixty-two patients (31.2%) met early switch criteria and potentially could have discontinued intravenous therapy 6.8 (standard deviation, 7.8) days sooner, and 65 patients (32.7%) met early discharge criteria and potentially could have been discharged 5.3 (standard deviation, 7.0) days sooner. Conclusions: Only 2% of patients were switched from intravenous to oral antibiotics in our study while almost one-third were early switch eligible. Additionally, one-third of hospitalized patients with methicillin-resistant Staphylococcus aureus complicated skin and soft tissue infections were early discharge eligible indicating opportunity for reducing intravenous therapy and days of hospital stay. These results provide insight into possible benefits of implementation of early switch/early discharge protocols in Brazil.

Actividad física y calidad de vida en personas con enfermedad renal crónica / Association of physical activity with quality of life in patients with chronic kidney disease

Background: Physical activity may improve quality of life in patients with chronic kidney disease. Aim: To assess the relationship between physical activity and quality of life in patients with Chronic Kidney Disease. Material and Methods: The Kidney Disease Quality of Life-36 (KDQOL-36) and the International Physical Activity questionnaire were answered by 130 patients with chronic kidney disease (74 women, 80 receiving renal substitution therapy). Sociodemographic variables were recorded. Results: Patients on renal substitution therapy with a time lapse since diagnosis of 0 to 6 months had higher levels of physical activity than those with longer time lapses (51.4 ± 12.5 and 34.6 ± 8.1 minutes respectively). Disease burden scores were lower among patients with renal substitution therapy. There was a direct correlation between levels of vigorous and moderate physical activity and the physical functioning dimension in the quality of life questionnaire for patients with more than 19 months of disease. The dimension general physical health was significantly associated with physical activity in women and patients with 7 to 18 months of diagnosis. The dimension disease burden was associated with physical activity in women, patients not receiving substitution therapy and those with 7 to 18 months of diagnosis. Conclusions: Moderate and vigorous physical activity is directly related to the dimensions physical functioning, the general perception of physical health and inversely related with the dimension burden of disease.

Antiretroviral changes during the first year of therapy / Mudanças de terapia antirretroviral durante o primeiro ano de tratamento

Summary Introduction: The Brazilian HIV/AIDS management and treatment guideline (PCDT), published in 2013, recommends and standardizes the use of highly active antiretroviral therapy (HAART) in all adult patients, in spite of LTCD4 count. This study aimed to analyze the first year of HAART use in patients from a reference center on HIV/AIDS management in Fortaleza, Ceará. Method: This descriptive study reviewed all prescription forms of antiretroviral regimens initiation and changes from January to July 2014. All antiretroviral regimen changes that occurred during the first year of therapy were evaluated. Data were analyzed with SPSS version 20. Mean, standard deviation and frequency, Student's t and Mann-Whitney tests calculations were used, with significance at p<0.05. Results: From 527 patients initiating HAART, 16.5% (n=87) had a regimen change in the first year. These patients were mostly male (59.8%; n=52), aged 20 to 39 years, with only one HAART change (72.4%; n=63). Efavirenz was the most often changed drug, followed by tenofovir, zidovudine and lopinavir/ritonavir. Mean time of HAART changes was 120 days, with adverse reactions as the most prevalent cause. HAART was effective in decreasing viral load since second month of treatment (p=0.003) and increasing LTCD4 lymphocytes since fifth month (p<0.001). Conclusion: The main cause of initial HAART changes was adverse reaction and most patients had only one change in the HAART regimen. HAART prescription was in accordance to the PCDT from 2013.

Resumo Introdução: O Protocolo Clínico e Diretrizes Terapêuticas para manejo da infecção pelo HIV em adultos (PCDT) de 2013 recomenda e normatiza início de terapia antirretroviral (TARV) em pacientes com qualquer contagem de LTCD4. O objetivo do estudo foi analisar o primeiro ano de TARV de pacientes em acompanhamento em um centro de referência em HIV/AIDS de Fortaleza, Ceará. Método: O estudo descritivo revisou formulários de solicitação de início e modificação de TARV em pacientes que iniciaram tratamento entre janeiro e julho de 2014. Foram avaliadas todas as mudanças que ocorreram durante o primeiro ano de terapia. Os dados foram analisados no programa Statistical Package for the Social Sciences (SPSS) versão 20. Foram calculados médias, desvios padrão, frequências, testes t Student e Mann-Whitney, com significância de p<0,05. Resultados: Dos 527 pacientes que iniciaram TARV, 16,5% (n=87) realizaram troca no primeiro ano. A maioria era do sexo masculino (59,8%; n=52), de 20 a 39 anos, com apenas uma mudança da TARV (72,4%; n=63). Efavirenz foi o fármaco mais substituído, seguido por tenofovir, zidovudina e lopinavir/ritonavir. O tempo médio de ocorrência das modificações da TARV foi de 120 dias, tendo reações adversas como causas principais. TARV foi efetiva na queda da carga viral desde o 2ºmês de tratamento (p=0,003) e na elevação de LTCD4 desde o 5º mês (p<0,001). Conclusão: Os principais fatores envolvidos em modificações de TARV inicial foram reações adversas, com apenas uma mudança de esquema na maioria dos pacientes. O manejo da TARV estava de acordo com o PCDT de 2013.

Abstract: This study compared the perception, knowledge, and use of generic drugs by adults in Pelotas, Rio Grande do Sul State, Brazil, using two cross-sectional population-based studies from 2002 and 2012. Study outcomes were: (a) prevalence of use of generics; (b) generics as a proportion of all medication; (c) users' perceptions of prices and quality; (d) users' knowledge of generics; and (e) strategies for acquisition of medicines. Prevalence of generics use increased from 3.6% (95%CI: 3.0-4.3) to 26.1% (95%CI: 24.5-27.7) in the 10-year period. Perceptions of prices and quality of generics remained stable, identification of characteristics that distinguish generics from other drugs improved (p < 0.001), and drug classification errors decreased (p < 0.001). There was a significant increase in acquiring medication by replacing prescribed drugs with generics. Between 2002 and 2012 there was an increase in knowledge and use of generics, while perception of lower prices and equivalent quality remained high.
