Requirements for Brazilian Outpatient Centers of Excellence in Hidradenitis Suppurativa: Consensus Co-Creative Study.

Background: Hidradenitis suppurativa (HS) is a chronic skin condition. Its complexity and impact on patients highlight the need for multidisciplinary care that can address the physical, psychological, and social aspects. Centers of excellence can ideally provide the necessary infrastructure, resources, and expertise to effectively treat HS. However, there are still no consolidated models of centers of excellence in HS, and establishing their foundations is an intricate research challenge. Purposely, design and co-creation as innovation techniques are helpful approaches to this type of research. Methods: In this study, we conducted a co-creation with consensus among HS specialists to propose the criteria and requirements to establish outpatient centers of excellence of HS in Brazil. We followed a linear process with mixed methods in 6 stages. Results: The process resulted in 10 categories for establishing outpatient centers, including their respective requirements, rationale, and classification. The categories include onboarding and welcoming; infrastructure and procedures; infusion therapy; flows and referrals; staffing; disease management; metrics during diagnosis; metrics during treatment; awareness and advocacy; research and education. Discussion: The idealized outpatient centers can play a role in the complete multidisciplinary treatment for HS and advancing the science of healthcare services by providing a focus for research, training, and translation of findings into practice.

Effectiveness of a multistep Pseudomonas aeruginosa eradication treatment protocol in children with cystic fibrosis in Brazil.

OBJECTIVE: Although various strategies have been proposed for eradicating Pseudomonas aeruginosa in patients with cystic fibrosis (CF), only a few employ multistep treatment in children colonized by that pathogen for the first time. The aim of this study was to describe the effectiveness of a three-phase eradication protocol, initiated after the first isolation of P. aeruginosa, in children with CF in Brazil. METHODS: This was a retrospective real-life study in which we reviewed the medical records of pediatric CF patients in whom the eradication protocol was applied between June of 2004 and December of 2012. The three-phase protocol was guided by positive cultures for P. aeruginosa in airway secretions, and the treatment consisted of inhaled colistimethate and oral ciprofloxacin. Success rates were assessed after each phase, as well as cumulatively. RESULTS: During the study period, 47 episodes of P. aeruginosa colonization, in 29 patients, were eligible for eradication. Among the 29 patients, the median age was 2.7 years, 17 (59%) were male, and 19 (65%) had at least one F508del allele. All 29 patients completed the first phase of the protocol, whereas only 12 and 6 completed the second and third phases, respectively. Success rates for eradication in the three treatment phases were 58.6% (95% CI: 40.7-74.5), 50.0% (95% CI: 25.4-74.6), and 66.7% (95% CI: 30.0-90.3), respectively. The cumulative success rate was 93.1% (95% CI: 78.0-98.1). Treatment failure in all three phases occurred in only 2 patients. CONCLUSIONS: In this sample of patients, the multistep eradication protocol was effective and had a high success rate.

Microbiological contamination of nebulizers used by cystic fibrosis patients: an underestimated problem.

OBJECTIVE: Home nebulizers are routinely used in the treatment of patients with cystic fibrosis (CF). This study aims to evaluate the contamination of nebulizers used for CF patients, that are chronically colonized by Pseudomonas aeruginosa, and the association of nebulizer contamination with cleaning, decontamination and drying practices. METHODS: A cross-sectional, observational, multicenter study was conducted in seven CF reference centers in Brazil to obtain data from medical records, structured interviews with patients/caregivers were performed, and nebulizer's parts (interface and cup) were collected for microbiological culture. RESULTS: overall, 77 CF patients were included. The frequency of nebulizer contamination was 71.6%. Candida spp. (52.9%), Stenotrophomonas maltophilia (11.9%), non-mucoid P. aeruginosa (4.8%), Staphylococcus aureus (4.8%) and Burkholderia cepacia complex (2.4%) were the most common isolated pathogens. The frequency of nebulizers' hygiene was 97.4%, and 70.3% of patients reported cleaning, disinfection and drying the nebulizers. The use of tap water in cleaning method and outdoor drying of the parts significantly increased (9.10 times) the chance of nebulizers' contamination. CONCLUSION: Despite the high frequency hygiene of the nebulizers reported, the cleaning and disinfection methods used were often inadequate. A significant proportion of nebulizers was contaminated with potentially pathogenic microorganisms for CF patients. These findings support the need to include patients/caregivers in educational programs and / or new strategies for delivering inhaled antibiotics.

RESUMO Objetivo: Nebulizadores caseiros são usados rotineiramente no tratamento de pacientes com fibrose cística (FC). Este estudo objetiva avaliar a contaminação de nebulizadores utilizados por pacientes de FC que estão cronicamente colonizados por Pseudomonas aeruginosa e a associação da contaminação do nebulizador com a higienização, esterilização e método de secagem. Métodos: Um estudo transversal, observacional, multicêntrico foi conduzido em sete centros de referência de FC no Brasil para obter dados de registros médicos; foram feitas entrevistas estruturadas com os pacientes/cuidadores e partes de nebulizadores (máscara e copo) foram coletados para cultura microbiológica. Resultados: No geral, 77 pacientes com FC foram incluídos. A frequência da contaminação do nebulizador foi de 71,6%. Candida spp. (52,9%), Stenotrophomonas maltophilia (11,9%), P. aeruginosa não mucoide (4,8%), Staphylococcus aureus (4,8%) e complexo Burkholderia cepacia (2.4%) foram os patógenos isolados mais comuns. A frequência de higienização dos nebulizadores foi de 97,4%, e 70,3% dos pacientes relata higienização, esterilização e secagem dos aparelhos. A lavagem com água da torneira e secagem das partes no tempo, em espaço aberto, aumentou significativamente (9 a 10 vezes) a chance de contaminação dos nebulizadores. Conclusões: Apesar dos relatos de frequente higienização dos nebulizadores, os métodos de limpeza e esterilização usados eram inadequados. Uma proporção significativa de nebulizadores foi contaminada com microrganismos potencialmente patogênicos para pacientes com FC. Estes resultados apoiam a necessidade de inclusão dos pacientes/cuidadores em programas educacionais e/ou novas estratégias para fornecimento de antibióticos inalatórios.
