Nosokomiale Infektionen (NKI) gehören zu den häufigsten Komplikationen eines Krankenhausaufenthaltes, insbesondere auf Intensivstationen mit einer Prävalenz von rund 18,65%. Die Folgen sind eine längere Verweildauer, erhöhte Morbidität und Letalität sowie höhere Kosten für das Gesundheitssystem. Die Erfassung NKI stellt einen wichtigen Qualitäts- Parameter für Intensivstationen dar. Ziel dieser Arbeit war es, die Übereinstimmung von nur nach KISS (Krankenhaus-InfektionsSurveillance System)- Definitionen erfassten Infektionen mit der klinisch diagnostizierten nosokomialen Infektion zu prüfen und den Zusammenhang zwischen ärztlicher Diagnose und den laborchemischen und klinisch erhobenen Kriterien darzustellen. Hierfür wurden auf einer interdisziplinären operativen Intensivstation nosokomiale Infektionen sowohl nach ITS- KISS (VAP, ZVK- assoziierte Infektionen und HWI), als auch nach ärztlicher Diagnose plus Beginn oder Eskalation einer Antibiotikatherapie erfasst. Zusätzlich zu den KISS-Parametern wurden laborchemische Entzündungsparameter (CRP und PCT) registriert. Es traten 32 Infektionen nach ITS- KISS und 69 Infektionen nach ärztlicher Diagnose auf. Acht Infektionen wurden ausschließlich nach KISS und 45 ausschließlich nach der ärztlichen Diagnose erfasst. Die Infektionsrate nach KISS für VAP lag bei 20,6, für ZVK bei 5,9 und für HWI bei 2 Infektionen, jeweils pro 1000 Devicetage. Spezifität und positiv prädiktiver Wert hinsichtlich der Vorhersage einer ärztlich diagnostizierten Infektion waren gering. Auch durch Kombination verschiedener Parameter wurden keine höheren prädiktiven Werte erreicht. Die geringe Übereinstimmung der beiden Methoden legt nahe, dass KISS die klinisch relevanten Infektionen nicht wesentlich erfasst und relevante Infektfoci nicht berücksichtigt werden, beispielsweise abdominelle Infektionen. Zudem erlauben die erfassten Laborparameter keine zuverlässige Diagnose bzw. Prädiktion einer nosokomialen Infektion. Die ärztliche Diagnose in Verbindung mit dem Beginn oder der Eskalation einer Antibiotikatherapie könnte eine vereinfachte Methode zur Surveillance nosokomialer Infektionen darstellen.

Introdução: A assistência à saúde é desafiada por eventos adversos evitáveis e mais da metade destes corresponde a Infecções Relacionadas à Assistência à Saúde (IRAS), com expressivas taxas de morbimortalidade e altos custos hospitalares. No entanto, não há investimentos em avaliação e reconhecimento da qualidade dos Programas de Prevenção e Controle de Infecções Relacionadas à Assistência à Saúde (PCIRAS). Objetivo: Realizar um diagnóstico de situação da estrutura e atuação dos PCIRAS em hospitais de pequeno porte, tendo como hipótese a conformidade mínima de 70%. Método: Estudo transversal, prospectivo e de avaliação processual no qual foram entrevistadas enfermeiras que atuam nos PCIRAS de catorze hospitais, de um total de 27, com até setenta leitos, adscritos no Departamento Regional de Saúde XVII, Estado de São Paulo, no período de 2015 a 2016. A avaliação aplicou quatro indicadores previamente validados: Estrutura Técnico-Operacional do Programa de Controle de Infecção Hospitalar (PCET), Diretrizes Operacionais de Controle e Prevenção de Infecção Hospitalar (PCDO), Sistema de Vigilância Epidemiológica de Infecção Hospitalar (PCVE) e Atividades de Controle e Prevenção de Infecção Hospitalar (PCCP). Resultados: O índice de conformidade geral dos indicadores foi de 69%, dispersão (dp) de (12,3), com valores médios de 61% (20,3 dp) para PCET, 85% (18,7 dp) para PCDO, 58% (39,5 dp) para PCVE e 75% (24,1 dp) para PCCP. O desempenho geral ficou pouco abaixo do esperado (70%) em decorrência dos indicadores PCET e PCVE. As instituições privadas apresentaram maiores índices de conformidade, bem como as que possuíam Unidade de Terapia Intensiva (UTI). Apesar, dos hospitais possuírem enfermeiros designados para PCIRAS (92,9%), somente em 23,1% das instituições privadas eles atuavam com dedicação exclusiva de seis horas. Foi observada relevância estatisticamente significativa para correlação entre os indicadores e as seguintes variáveis: presença de UTI (PCET e PCVE), representação do SCIH (PCDO) e carga horária diária do enfermeiro (PCET). Ao contrário, não foi observada relevância estatística para: presença de acreditação e carga horária do segundo profissional do SCIH. Conclusões: diante do exposto, os hospitais de pequeno porte apresentam dificuldades para instituir PCIRAS nos moldes preconizados pela legislação (Portaria 8 n. 2.616/1998). Faz-se necessário o estabelecimento de recomendações e políticas públicas viáveis e que permitam um programa efetivo de prevenção de infecções nestas instituições. / Introduction: Healthcare is challenged by preventable adverse events and more than half of these events are Healthcare-Associated Infections (HAI), with significant morbidity and mortality rates and high hospital costs. However, there is no investment in the assessment and recognition of the quality of the Prevention and Control Programs Related to Healthcare-Associated Infections. Purpose: Provide a diagnosis of the situation of the structure and performance of Programs of HAI in small-sized hospitals, with the hypothesis of a minimal compliance of 70%. Method: Cross-sectional, prospective and process evaluation study presenting interviews with nurses working in Programs of HAI of 14 hospitals, out of a total of 27, with up to 70 beds, ascribed in the Regional Health Department XVII of the state of Sao Paulo, in the period from 2015 to 2016. The evaluation applied four previously validated indicators: Technical-Operational Structure of the Hospital-Acquired Infection Control Program (PCET), Operational Guidelines for the Control and Prevention of Hospital-Acquired Infections (PCDO), Hospital-Acquired Infection Epidemiological Surveillance System (PCVE) and Activities of Infection Control and Prevention (PCCP). Results: The overall compliance rate of the indicators was 69%, dispersion (dp) of (12.3), with average values of 61% (20.3 dp) for PCET, 85% (18.7 dp) for PCDO, 58 % (39.5 dp) for PCVE and 75% (24.1 dp) for PCCP. The overall performance was slightly lower than expected (70%) as a result of PCET and PCVE indicators. Private institutions had higher rates of compliance, as well as those having an Intensive Care Unit (ICU). Though the hospitals have nurses assigned to PCIRAS (92.9%), they worked in an exclusive six hours system only in 23.1% of the private institutions. A statistically significant relevance was observed for correlation between the indicators and the following variables: presence of ICU (PCET and PCVE), representation of the SCIH (PCDO) and daily workload of nurses (PCET). On the contrary, there was no statistical significance for: presence of accreditation and workload of the second professional of the SCIH. Conclusions: considering the above, the small hospitals find it difficult to use PCIRAS along the lines recommended by law (Ordinance no. 2,616/1998). It is necessary to establish recommendations and viable public policies, as well as providing an effective program to prevent infections in these institutions.

Study Objective: To compare the rates and severity of hospital-acquired Clostridium difficile infection (CDI) among patients taking proton pump inhibitors (PPIs) versus those not taking PPIs. Design: Retrospective, single-center, cohort study. Setting: Tertiary community hospital with a teaching service. Patients: A total of 41,663 patients with CDI who were hospitalized between January 2013 and May 2014; of those, 17,471 patients (41.9%) had received at least one dose of a PPI (PPI group), and 24,192 patients (58.1%) had no PPI exposure (control group). Measurements and Main Results: A total of 348 patients had CDI during the study period, with 269 cases present on admission. Hospital-acquired CDI was defined as CDI diagnosis occurring on or after the third calendar day of admission. After excluding those patients with CDI on admission, 65 (0.38%) of 17,302 patients later developed CDI in the hospital in the PPI group compared with only 14 (0.058%) of 24,092 patients in the control group. Of these patients, 36 patients (0.21%) in the PPI group met the definition of severe CDI compared with 8 (0.03%) in the control group. This demonstrated an unadjusted relative risk (RR) of 6.46 (95% confidence interval [CI] 3.63–11.51, p<0.0001) of developing hospital-acquired CDI and an unadjusted RR of 6.27 (95% CI 2.91–13.48, p<0.0001) of developing severe CDI while taking a PPI. When evaluating only patients who developed severe-complicated CDI, there were 22 cases in the PPI group and 2 cases in the control group, demonstrating an unadjusted RR of 15.3 (95% CI 3.6–65.13, p=0.0002) of developing severe-complicated CDI. Confounding variables were similar between groups. Conclusion: PPI use was associated with an increase in both the rate and severity of hospital-acquired CDI.

No / Pseudomonas aeruginosa is a versatile pathogen associated with a broad spectrum of infections in humans. In healthcare settings the bacterium is an important cause of infection in vulnerable individuals including those with burns or neutropenia or receiving intensive care. In these groups morbidity and mortality attributable to P. aeruginosa infection can be high. Management of infections is difficult as P. aeruginosa is inherently resistant to many antimicrobials. Furthermore, treatment is being rendered increasingly problematic due to the emergence and spread of resistance to the few agents that remain as therapeutic options. A notable recent development is the acquisition of carbapenemases by some strains of P. aeruginosa. Given these challenges, it would seem reasonable to identify strategies that would prevent acquisition of the bacterium by hospitalised patients. Environmental reservoirs of P. aeruginosa are readily identifiable, and there are numerous reports of outbreaks that have been attributed to an environmental source; however, the role of such sources in sporadic pseudomonal infection is less well understood. Nevertheless there is emerging evidence from prospective studies to suggest that environmental sources, especially water, may have significance in the epidemiology of sporadic P. aeruginosa infections in hospital settings, including intensive care units. A better understanding of the role of environmental reservoirs in pseudomonal infection will permit the development of new strategies and refinement of existing approaches to interrupt transmission from these sources to patients.

It analyzed a sample of 1500 patients, who have gone through surgery in all four hospitals of the city. Structure indicators assess the Surgical Center according to the following items: availability of a circulating nurse for every room, adequate placement of antiseptics for surgical hand antisepsis, and automatic door closer. Process indicators assess the following procedures from the preoperative period to the postoperative period: length of preoperative hospitalization, trichotomy (time), trichotomy (method), antisepsis of the operative field with adequate solution, antibiotic administered up to one hour before the surgical incision, duration of antibiotic prophylaxis &#8804; 24 hours, presence of chemical integrator in the surgical boxes. The indicators assessed through the observation of the structure of Surgical Centers and patients' files. Socio-demographic data was collected through interview. Only two out of four hospitals analyzed satisfied all three of the structure indicators, while one hospital satisfied only one of the indicators. Process indicators showed bigger differences among the hospitals. However, even the hospitals that responded positively to all the structure indicators were considered unsatisfactory in the process indicators. Several failures were evident in all of the hospitals, not only in the process but also in structure offered to surgical patient care. This increases the probabilities of SSI / Estudo descritivo em que se investigou a utilização de indicadores de processo e estrutura na prevenção de infecção de sítio cirúrgico (ISC) na cidade de Pelotas. A análise foi realizada com uma amostra de 1.500 pacientes, submetidos a procedimentos cirúrgicos nas quatro instituições hospitalares da cidade. Os indicadores de estrutura avaliam o Centro Cirúrgico através dos seguintes itens: disponibilidade de um circulante para cada sala, disposição adequada de antisséptico para a antissepsia cirúrgica das mãos e o mecanismo autônomo de manutenção de portas fechadas. Os indicadores de processo avaliam os cuidados do pré ao pós-operatório: tempo de internação pré-operatória, tricotomia (tempo), tricotomia (método), antissepsia do campo operatório com solução adequada, realização de antibioticoprofilaxia até uma hora antes da incisão cirúrgica, duração do antibiótico profilaxia &#8804; 24h e presença de integrador químico nas caixas cirúrgicas. A avaliação dos indicadores foi realizada através da observação na estrutura dos Centros Cirúrgicos e nos prontuários dos pacientes, os dados sociodemográficos foram coletados através de entrevista. Somente duas, das quatro instituições avaliadas, satisfizeram aos três indicadores de estrutura, e um hospital atendeu somente um indicador. Os indicadores de processo demonstraram maior diferença entre as instituições. Porém mesmo as duas instituições que atenderam plenamente os indicadores de estrutura obtiveram avaliação insatisfatória aos indicadores de processo. Foi possível verificar inúmeras falhas em todas as instituições, tanto no processo como na estrutura oferecida para o atendimento ao paciente cirúrgico, o que aumenta a probabilidade do desenvolvimento de ISC
