Abstract Introduction: Patient safety culture is considered an important structural component of the services, which promotes the implementation of safe practices and the reduction of adverse events. Objective: To identify the factors associated with patient safety culture in adult intensive care units in large hospitals in Belo Horizonte. Method: Cross-sectional survey and multicenter study. A total of 168 health professionals from four units (A, B, C and D) of adult intensive care participated. The questionnaire "Hospital Survey on Patient Safety Culture" was used. The patient's level of safety culture was considered as a dependent variable, and sociodemographic and labor aspects were the independent variables. Descriptive statistics were used and a multiple logistic regression model was developed to analyze the associated factors. Results: An association was identified between the type of hospital and eleven dimensions of the safety culture. In terms of function, the doctors, nursing technicians, and nurse were related to three dimensions; gender with two dimensions, and time working in the sector with one dimension. Conclusion: It was evidenced that the type of hospital, function, time working in the sector, and gender were associated with the dimensions of patient safety culture.

What Are the Ready-to-Use Endoscope Channels Hiding?: Unraveling the Risks of Safe Reuse.

Contamination due to failures or omissions in the reprocessing steps of gastrointestinal endoscopes is common in clinical practice. Ensuring the proper execution of each step is a challenge for reprocessing personnel. This cross-sectional study was conducted in an endoscopy setting between March and May 2021. We performed interviews about reprocessing practices, analyzed the life history of the equipment, and performed inspections through a borescope video of gastrointestinal endoscope channels that were stored and ready for use. A borescope is a complementary tool used to validate endoscope reprocessing, evaluate the internal visualization of channels, and identify changes that can compromise the safety of its use, which are often not detected in the leak test. Thirteen biopsy channels from stored gastrointestinal endoscopes were inspected. We found that 85% had stains and grooves, 69% contained moisture, and 46% had debris. There was at least one noncompliance issue in all of the channels inspected.

Criteria for the Use, Processing, and Disposal of Flexible Endoscope Cleaning Brushes.

Objectives: To ensure effectiveness in the endoscope channel cleaning process, using functional brushes that are in good condition is necessary. This study sought to identify the criteria for acquiring, using, and disposing of cleaning brushes at endoscopy facilities in Brazil. We further sought to evaluate the conditions of the cleaning brushes in use in the facilities. Methods: This cross-sectional study was conducted between July 2021 and January 2022. Personnel responsible for processing endoscopes were interviewed regarding the use, processing, and disposal of flexible endoscope cleaning brushes. In addition, the brushes used to clean the equipment were inspected. Results: All participants interviewed reported the practice of brushing endoscope channels. Of them, 60% noted the use of disposable brushes, with 40% using reusable brushes. None of the facilities interviewed reported discarding disposable brushes after use. The protocols for disposal of brushes included disposing due to bristle wear (70%), disposal at the end of the day (20%), and an absence of disposal protocols (10%). In addition, 30% of facilities did not clean the bristles before reintroducing them into the channel/lumen, and no facility had an established routine for cleaning brushes between uses. Inspection of brushes revealed that only 20% of facilities had new brushes with no signs of wear or damage. Conclusion: The use of inappropriate brushes/sponges for cleaning endoscope channels and the lack of criteria for the reuse and disposal of brushes increases the risk of cross-contamination, internal damage to channels, and biofilm formation.

Prevenção da infecção urinária associada a cateter: efeito de uma intervenção no conhecimento de intensivistas / Prevention of catheter-associated infection: effect of an intervention on the knowledge of intensivists

A infecção do trato urinário é um dos agravos mais comuns durante a assistência à saúde, sobretudo na unidade de terapia intensiva, e, em sua maioria, é associada ao uso do cateter vesical, contribuindo, de forma significativa, na mortalidade, na morbidade e no custo de tratamento. O objetivo foi avaliar o efeito de uma intervenção educacional no conhecimento dos profissionais intensivistas sobre medidas de prevenção de infecção do trato urinário associada ao uso do cateter vesical. Trata-se de um estudo de intervenção, do tipo antes e depois, realizado em unidade de terapia intensiva com dez leitos de um hospital de alta complexidade. A coleta de dados contemplou três momentos: pré-intervenção, intervenção e pós-intervenção, realizada entre janeiro de 2018 a janeiro de 2019. Na pré e na pós-intervenção, foi feita entrevista por meio de um questionário estruturado. A intervenção ocorreu por sessão de treinamento com metodologias ativas e demonstrações práticas. Observou-se uma tendência ao aumento do conhecimento em todos os itens avaliados para prevenção da infecção do trato urinário associada ao uso do cateter vesical, com diferenças significativas (p<0,05) nos momentos para higienização das mãos, indicações para inserção do cateter vesical, medidas de barreira na técnica de inserção e prevenção dessa infecção durante a manipulação e manutenção do cateter vesical. A intervenção proporcionou aumento do conhecimento dos profissionais sobre as medidas de prevenção. Entretanto, lacunas relacionadas a estas práticas ainda foram verificadas e intervenções em longo prazo devem ser conduzidas com vistas à melhoria e segurança do cuidado.

Urinary tract infection is one of the most common problems during health care, especially in the intensive care unit, and is mostly associated with the use of a urinary catheter, contributing significantly to mortality, morbidity, and the cost of treatment. The objective of this study was to evaluate the effect of an educational intervention on the knowledge of intensive care professionals upon measures to prevent urinary tract infections associated with the use of a urinary catheter. This is a before-and-after intervention study, carried out in a ten-bed intensive care unit in a high-complexity hospital. Data collection included three moments: pre-intervention, intervention, and post-intervention, carried out between January 2018 and January 2019. In the pre- and post-intervention, an interview was carried out using a structured questionnaire. The intervention took place through a training session with active methodologies and practical demonstrations. There was a trend towards increased knowledge in all items evaluated for the prevention of urinary tract infections associated with the use of a urinary catheter, with significant differences (p<0.05) concerning hand hygiene, indications for catheter insertion bladder, barrier measures in the insertion technique, and prevention of this infection during manipulation and maintenance of the bladder catheter. The intervention provided an increase in the knowledge of professionals about prevention measures. However, gaps related to these practices were still being verified and long-term interventions should be conducted with a view to the improvement and safety of care.

ABSTRACT Objective: to analyze the incidence of surgical site infections (SSI) in patients submitted to neurological and orthopedic surgeries and their determinants in a public hospital. Method: retrospective cohort study, conducted between patients submitted to neurological and orthopedic surgeries, from January 2015 to December 2020. Results: of the 3,029 surgical procedures performed, 1,327 (43.8%) were neurosurgical; and 1,702 (56.2%) were orthopedic. The incidence of SSI was 6.7% (89) in neurosurgeries and 3.3% (56) in orthopedic surgery. The overall rate and death rates were 4.8% and 12.4%, respectively. In the univariate analysis, the risk factors associated with SSI in neurosurgeries involved surgical time (>231 minutes), an American Society of Anesthesiologists score greater than two and emergency surgeries; the risk factors for orthopedic procedures were emergency surgeries, preoperative hospitalization time (> four days), and surgical procedures (>149 minutes). In the multivariate analysis, emergency surgeries and longer surgical time remained as risk factors for SSI for both specialties; the SSI risk factors for orthopedic and neurological surgeries were preoperative hospitalization time and ASA classification, respectively. Conclusion: the incidence rate of SSI and mortality, as well as the risk factors identified in this study, should be considered in order to develop strategies aimed at preventing and controlling these infections.

Cleaning of in-hospital flexible endoscopes: Limitations and challenges.

OBJECTIVE: to analyze the cleaning process of gastroscopes, colonoscopes and duodenoscopes in eight in-hospital health services. METHOD: a cross-sectional study conducted with 22 endoscopes (eight gastroscopes, eight colonoscopes and six duodenoscopes), and microbiological analysis of 60 samples of air/water channels (all endoscopes) and elevator (duodenoscopes), in addition to protein testing. Descriptive statistics with calculation of frequencies and central tendency measures was used in data analysis. RESULTS: the processing of 22 endoscopes was monitored with microbiological analysis for 60 channels. In the pre-cleaning procedure, in 82.3% (14/17) of the devices, gauze was used in cleaning the insertion tube. Incomplete immersion of the endoscope in detergent solution occurred in 72.3% (17/22) of the cases, and in 63.6% (14/22) there was no standardization of filling-in of the channels. Friction of the biopsy channel was not performed in 13.6% (3/22) of the devices. In the microbiological analysis, 25% (7/32) of the samples from the stored endoscopes were positive for microbial growth (from 2x101 to 9.5x104 CFU/mL), while after processing, contamination was 32% (9/28). Protein residues in the elevator channel were detected in 33% of duodenoscopes. CONCLUSION: the results indicate important gaps in the stages of pre-cleaning and cleaning of endoscopes that, associated with presence of protein residues and growth of microorganisms of epidemiological importance, indicate limitations in safety of the processing procedures, which can compromise the disinfection processes and, consequently, their safe use among patients subjected to such tests.

Impact of surgical checklist and its completion on complications and mortality in urgent colorectal procedures.

OBJECTIVE: to assess the impact of using a surgical checklist and its completion on complications such as surgical site infection (SSI), reoperation, readmission, and mortality in patients subjected to urgent colorectal procedures, as well as the reasons for non adherence to this instrument in this scenario, in a university hospital in Ottawa, Canada. METHODS: this is a retrospective, epidemiological study. We collected data from an electronic database containing information on patients undergoing urgent colorectal operations, and analyzed the occurrence of SSI, reoperation, readmission, and death in a 30 day period, as well as the completion of the checklist. We conducted a descriptive statistical analysis and logistic regression. RESULTS: we included 5,145 records, of which 5,083 (98.8%) had complete checklists. As for the outcomes evaluated, cases with complete checklists displayed higher SSI rate, 9.1% vs. 6.5% (p=0.466), lower reoperation rate, 5% vs.11.3% (p=0.023), lower readmission rates, 7.2% vs. 11.3% (p=0.209), and lower mortality, 3.0% vs. 6.5% (p=0.108) than cases with incomplete ones. CONCLUSION: there was a high level of checklist completion and a larger number of the outcomes in the reduced percentage of incomplete checklists found, demonstrating the impact of its utilization on the safety of patients undergoing urgent operations.

Storage of gastrointestinal endoscopes: when is the safe time for re-use?

OBJECTIVES: to identify the safe storage time for the use of flexible gastrointestinal endoscopes after high-level disinfection, as well as the defining criteria for this time. METHODS: an integrative literature review was carried out in the Virtual Health Library, PubMed, Scopus, and Web of Science, considering original articles published since 2000. RESULTS: eleven articles were selected, whose storage times ranged from 1 to 56 days, with a predominance of one to seven days (73%). Several criteria were used to define this time, predominantly the premise of efficient processing (100%), use of alcohol flush (64%), use of drying cabinets (18%), among others. CONCLUSIONS: the criteria for determining the storage time did not show a consensus for clinical practice. Expanding the discussion of this theme with the definition of the minimum necessary conditions is of fundamental importance for the reduction of risks and safety of the procedure and the patient.

Resumo Objetivo: analisar o processo de limpeza de gastroscópios, colonoscópios e duodenoscópios em oito serviços de saúde intra-hospitalar. Método: estudo transversal com 22 endoscópios, sendo oito gastroscópios, oito colonoscópios e seis duodenoscópios, e análise microbiológica de 60 amostras dos canais de ar/água (todos os endoscópios) e elevador (duodenoscópios), além de teste de proteína. Na análise dos dados, utilizou-se estatística descritiva, com cálculo de frequências e medidas de tendência central. Resultados: o processamento de 22 endoscópios foi acompanhado com análise microbiológica de 60 canais. Na pré-limpeza, em 82,3% (14/17) dos equipamentos, foi utilizada gaze na limpeza do tubo de inserção. A imersão incompleta do endoscópio em solução detergente ocorreu em 72,3% (17/22) dos casos, e em 63,6% (14/22) não havia padronização do preenchimento dos canais. A fricção do canal de biópsia não foi realizada em 13,6% (3/22) dos equipamentos. Na análise microbiológica, 25% (7/32) das amostras dos endoscópios armazenados foram positivas para crescimento microbiano (2x101 a 9,5x104 UFC/mL), enquanto após o processamento, a contaminação foi de 32% (9/28). Resíduos de proteína no canal do elevador foram detectados em 33% dos duodenoscópios. Conclusão: os resultados apontam lacunas importantes nas etapas de pré-limpeza e limpeza dos endoscópios que, associadas à presença de resíduos de proteína e ao crescimento de microrganismo de importância epidemiológica, sinalizam limitações na segurança do processamento, que podem comprometer os processos de desinfecção e consequentemente seu uso seguro entre pacientes submetidos a tais exames.

La fricción del canal de biopsia no se realizó en el 13,6% (3/22) de los equipos. En el análisis microbiológico, el 25% (7/32) de las muestras endoscópicas almacenadas dio positivo para crecimiento microbiano (2x101 a 9,5x104 UFC/ml), mientras que después del procesamiento, la contaminación fue del 32% (9/28). Se detectaron residuos de proteína en el canal elevador en el 33% de los duodenoscopios. Conclusión: los resultados indican que hay importantes lagunas en las etapas de prelimpieza y limpieza de los endoscopios que, junto con la presencia de residuos de proteínas y del crecimiento de microorganismos de importancia epidemiológica, indican limitaciones en la seguridad del procesamiento, que pueden comprometer los procesos de desinfección y, por ende, el uso seguro en los pacientes que se someten a esos procedimientos.

Impact of surgical checklist and its completion on complications and mortality in urgent colorectal procedures.

OBJECTIVE: to assess the impact of using a surgical checklist and its completion on complications such as surgical site infection (SSI), reoperation, readmission, and mortality in patients subjected to urgent colorectal procedures, as well as the reasons for non adherence to this instrument in this scenario, in a university hospital in Ottawa, Canada. METHODS: this is a retrospective, epidemiological study. We collected data from an electronic database containing information on patients undergoing urgent colorectal operations, and analyzed the occurrence of SSI, reoperation, readmission, and death in a 30 day period, as well as the completion of the checklist. We conducted a descriptive statistical analysis and logistic regression. RESULTS: we included 5,145 records, of which 5,083 (98.8%) had complete checklists. As for the outcomes evaluated, cases with complete checklists displayed higher SSI rate, 9.1% vs. 6.5% (p=0.466), lower reoperation rate, 5% vs.11.3% (p=0.023), lower readmission rates, 7.2% vs. 11.3% (p=0.209), and lower mortality, 3.0% vs. 6.5% (p=0.108) than cases with incomplete ones. CONCLUSION: there was a high level of checklist completion and a larger number of the outcomes in the reduced percentage of incomplete checklists found, demonstrating the impact of its utilization on the safety of patients undergoing urgent operations.

Challenges for adherence to bacterial resistance actions in large hospitals.

OBJECTIVES: to identify the challenges to actions to contain bacterial resistance. METHODS: cross-sectional study, carried out in 30 large-sized hospitals in Minas Gerais, from 2018 to 2019. The professionals were interviewed, and the environment and actions to prevent bacterial resistance were observed. RESULTS: regarding the knowledge of health care professionals about the measures of bacterial resistance prevention, 78.3% did not correctly describe the five moments of hand hygiene, and 76.6% did not correctly describe the measures to control bacterial resistance. The simple hygiene of hands, followed by alcohol rubbing was predominant (48.3%) among workers, and soap dispensers were next to alcohol dispensers in 58.3% of the nursing stations in care units. CONCLUSIONS: the insufficient knowledge from the professionals, which is a failure related to the physical structure and to personal protection equipment, are factors that difficult the adherence to measures to contain bacterial resistance in hospitals.

Impact of the contamination time by Escherichia coli on biofilm formation in surgical instruments.

OBJECTIVES: to evaluate the microbial load and adherence of Escherichia coli in different areas of the surgical instrument surface exposed to experimental contamination over time. METHODS: experimental study in which fragments of crile forceps (serrated, rod and rack) were contaminated by immersion in Tryptic Soy Broth, containing 106 CFU/mL of E. coli, for 1, 2, 4, 6, 8, 12 and 24 hours. Microbial load and bacterial adherence were evaluated using microbiological culture and scanning electron microscopy, respectively. RESULTS: there was an increase in the microbial load on the surgical instrument, proportional to the contamination interval, ranging from 102 after 1 hour to 105 CFU/cm2 in 24 hours. The presence of exopolysaccharide was detected after two hours of contamination. CONCLUSIONS: microbial load and adhesion of E. coli increased over time, reaching 105 CFU/cm2 after 24 hours of contamination, starting biofilm formation after two hours.

Overview of the actions to combat bacterial resistance in large hospitals.

OBJECTIVE: to analyze, in the clinical practice of large hospitals, how the adoption of measures to prevent and control the spread of bacterial resistance has occurred, and to propose a score for the institutions' adherence. METHOD: a cross-sectional study carried out in 30 large hospitals of Minas Gerais, from February 2018 to April 2019, after approval by the Ethics and Research Committee. Interviews were conducted with hospital managers, with Hospital Infection Control Services coordinators, and with the care coordinators of the Inpatient Units and Intensive Care Center. In addition, observations were made of the adoption of preventive measures by the multidisciplinary team in the care units. RESULTS: in the 30 participating hospitals, 93.3% (N=28) had protocols for prophylactic antibiotics, and 86.7% (N=26) performed their audit, 86.7% (N=26) for therapeutic antibiotics and 83.3% (N=25) their audit; 93.3% (N=56) used gloves and cloaks for patients in contact precautions, and 78.3% (N=47) of the professionals were unaware of or answered incompletely on the five moments for hand hygiene. In the score to identify the adoption of measures to control bacterial resistance, 83.3% (N=25) of the hospitals were classified as partially compliant, 13.3% (N=04) as deficient, and 3.4% (N=01) as non-adoption. CONCLUSION: it was found that the recommended measures to contain bacterial resistance are not consolidated in the clinical practice of the hospitals.
