Estudo exploratório das iniciativas acerca da segurança do paciente em hospitais do Rio de Janeiro

Trata-se de um estudo descritivo e exploratório, que se apoiou na estatística descritiva para abordagem dos resultados produzidos. Tem como objeto as iniciativas para segurança do paciente, implementadas pelos gerentes de risco em hospitais do município do Rio de Janeiro. O estudo teve como objetivo: analisar as iniciativas implementadas pelos gerentes de risco para garantir a segurança do paciente, considerando as iniciativas nacionais e mundiais existentes. Foi desenvolvido em cinco hospitais do Rio de Janeiro, com quatorze gerentes de risco. A técnica utilizada foi a aplicação de um questionário semiestruturado, composto por questões fechadas e abertas sobre as iniciativas para segurança do paciente. Foi verificado que todos realizam atividades voltadas para educação continuada. As menos desenvolvidas são ações de tecno, hemo e farmacovigilância (29%). A maioria informou que se orienta pela Agência Nacional de Vigilância Sanitária, assim como implementa quatro programas para segurança do paciente: a identificação dos pacientes (100%), seguida da assistência limpa é uma assistência mais segura (86%), controle de infecção da corrente sanguínea associada ao cateter (64%) e cirurgia segura, salva vidas (64%). A maior parte dos gerentes de risco desconhece os cinco protocolos operacionais padronizados da Joint Comission on Acreditation of Healthcarecare Organizations e o conteúdo da campanha dos 5 milhões de vidas do Institute for Healthcare Improvement. Os eventos adversos cujo monitoramento é prioritário para os gerentes de risco, são queda do leito (43%) e infecções (36%). A maior parte deles (57%) informa utilizar a análise de causa raiz e análise do modo e efeito da falha como ferramentas de monitoramento de eventos adversos. Conclui-se que grande parte das iniciativas para segurança do paciente são implementadas pelos gerentes de risco, o que vai ao encontro do que é sugerido atualmente, no entanto as iniciativas mais citadas são as iniciativas já divulgadas pelas instituições de referência para segurança do paciente, e que exigem poucos investimentos para serem implementadas, logo é essencial mais ações de capacitação dos gerentes de risco e de desenvolvimento de uma cultura de segurança no ambiente hospitalar.

Variation in the type and frequency of postoperative invasive Staphylococcus aureus infections according to type of surgical procedure.

OBJECTIVE: To determine the epidemiological characteristics of postoperative invasive Staphylococcus aureus infection following 4 types of major surgical procedures.design. Retrospective cohort study. SETTING: Eleven hospitals (9 community hospitals and 2 tertiary care hospitals) in North Carolina and Virginia. PATIENTS: Adults undergoing orthopedic, neurosurgical, cardiothoracic, and plastic surgical procedures. METHODS: We used previously validated, prospectively collected surgical surveillance data for surgical site infection and microbiological data for bloodstream infection. The study period was 2003 through 2006. We defined invasive S. aureus infection as either nonsuperficial incisional surgical site infection or bloodstream infection. Nonparametric bootstrapping was used to generate 95% confidence intervals (CIs). P values were generated using the Pearson chi2 test, Student t test, or Wilcoxon rank-sum test, as appropriate. RESULTS: In total, 81,267 patients underwent 96,455 procedures during the study period. The overall incidence of invasive S. aureus infection was 0.47 infections per 100 procedures (95% CI, 0.43-0.52); 227 (51%) of 446 infections were due to methicillin-resistant S.aureus. Invasive S. aureus infection was more common after cardiothoracic procedures (incidence, 0.79 infections per 100 procedures [95%CI, 0.62-0.97]) than after orthopedic procedures (0.37 infections per 100 procedures [95% CI, 0.32-0.42]), neurosurgical procedures (0.62 infections per 100 procedures [95% CI, 0.53-0.72]), or plastic surgical procedures (0.32 infections per 100 procedures [95% CI, 0.17-0.47]) (P < .001). Similarly, S. aureus bloodstream infection was most common after cardiothoracic procedures (incidence, 0.57 infections per 100 procedures [95% CI, 0.43-0.72]; P < .001, compared with other procedure types), comprising almost three-quarters of the invasive S. aureus infections after these procedures. The highest rate of surgical site infection was observed after neurosurgical procedures (incidence, 0.50 infections per 100 procedures [95% CI, 0.42-0.59]; P < .001, compared with other procedure types), comprising 80% of invasive S.aureus infections after these procedures. CONCLUSION: The frequency and type of postoperative invasive S. aureus infection varied significantly across procedure types. The highest risk procedures, such as cardiothoracic procedures, should be targeted for ongoing preventative interventions.

Influenza vaccination of household contacts of newborns: a hospital-based strategy to increase vaccination rates.

We implemented a hospital-based influenza vaccination program for household contacts of newborns. Among mothers not vaccinated prenatally, 44.7% were vaccinated through the program, as were 25.7% of fathers. A hospital-based program provided opportunities for vaccination of household contacts of newborns, thereby facilitating better adherence to national vaccination guidelines.

Host genetics and HIV-1: the final phase?

This is a crucial transition time for human genetics in general, and for HIV host genetics in particular. After years of equivocal results from candidate gene analyses, several genome-wide association studies have been published that looked at plasma viral load or disease progression. Results from other studies that used various large-scale approaches (siRNA screens, transcriptome or proteome analysis, comparative genomics) have also shed new light on retroviral pathogenesis. However, most of the inter-individual variability in response to HIV-1 infection remains to be explained: genome resequencing and systems biology approaches are now required to progress toward a better understanding of the complex interactions between HIV-1 and its human host.

The art of auscultation: evaluating a patient's respiratory pathology

This article considers national policy drivers promoting the development of advanced assessment skills and practical procedures for the safe and effective use of the stethoscope in the clinical area. The evidence base underpinning effective use of the stethoscope in clinical practice is explored, including the preparation of the patient and the environment, applying infection control policies, and placing an emphasis on privacy and dignity. This is followed by a practical guide to auscultation technique of the respiratory system for nurses developing advanced practice skills.

Effect of a multifaceted intervention on adherence to hand hygiene among healthcare workers:A cluster-randomized trial

OBJECTIVES. Adherence to hand hygiene among healthcare workers (HCWs) is widely believed to be a key factor in reducing the spread of healthcare-associated infection. The objective of this study was to evaluate the impact of a multifaceted intervention to increase rates of adherence to hand hygiene among HCWs and to assess the effect on the incidence of hospital-acquired methicillin-resistant Staphylococcus aureus (MRSA) colonization. DESIGN. Cluster-randomized controlled trial. SETTING. Thirty hospital units in 3 tertiary care hospitals in Hamilton, Ontario, Canada. INTERVENTION. After a 3-month baseline period of data collection, 15 units were randomly assigned to the intervention arm (with performance feedback, small-group teaching seminars, and posters) and 15 units to usual practice. Hand hygiene was observed during randomly selected 15-minute periods on each unit, and the incidence of MRSA colonization was measured using weekly surveillance specimens from June 2007 through May 2008. RESULTS. We found that 3,812 (48.2%) of 7,901 opportunities for hand hygiene in the intervention group resulted in adherence, compared with 3,205 (42.6%) of 7,526 opportunities in the control group (P <.001; independent t test). There was no reduction in the incidence of hospital-acquired MRSA colonization in the intervention group. CONCLUSION. Among HCWs in Ontario tertiary care hospitals, the rate of adherence to hand hygiene had a statistically significant increase of 6% with a multifaceted intervention, but the incidence of MRSA colonization was not reduced.

Adherence to hand hygiene and risk factors for poor adherence in 13 Ontario acute care hospitals

Multicenter studies assessing hand hygiene adherence and risk factors for poor performance are scarce. In an observational study involving 13 hospitals across Ontario, Canada, we found a mean adherence rate of 31.2%, and that adherence was positively associated with nurses, single rooms, contact precautions, and the availability of alcohol hand rub dispensers.

Surviving but stigmatised:Making sense of living with Burkholderia cepacia

Infection control policies recommend segregation of people with Cystic Fibrosis (CF) according to bacterial status. This involves isolating those people with cepacia from all other CF patients in order to prevent additional infection. These policies are reliant on the understanding and adherence of those colonised with cepacia. Service user reports suggest that emotions like anxiety and anger are aroused when those with cepacia are faced with cross infection measures (UK CF Trust, 2009). No studies to date investigate this anecdotal emotional reaction. This research was conducted to ask what it is like to live with cepacia, using in depth interviews. A phenomenological approach was used. Three themes that appeared to characterise the experience of living with cepacia were identified: (1) Lost Identity: cepacia can challenge one’s self identity, and along with cross infection measures lead to feeling objectified and even alienated from the CF group identity. (2) Status: Condemned: being colonised with cepacia brings with it knowledge of a certain type of restricted future, and an imagined death. There is loss of normality and hope. (3) I Am Cepacia: making decisions about preventing cross infection is influenced by medical knowledge as well as human emotions and social information; therefore adherence to these measures is fluid and contextual. These themes have real world clinical implications for all CF services, where preventing the spread of cepacia is paramount. Responsibility for cross infection is a burden and requires knowledge and understanding from both those living with and without cepacia. We need to see beyond the bacteria to the person.

Hospital antibiotic use and its relationship to age-adjusted comorbidity and alcohol-based hand rub consumption

SUMMARY The objective of this study was to evaluate the effect of age-adjusted comorbidity and alcohol-based hand rub on monthly hospital antibiotic usage, retrospectively. A multivariate autoregressive integrated moving average (ARIMA) model was built to relate the monthly use of all antibiotics grouped together with age-adjusted comorbidity and alcohol-based hand rub over a 5-year period (April 2005-March 2010). The results showed that monthly antibiotic use was positively related to the age-adjusted comorbidity index (concomitant effect, coefficient 1·103, P = 0·0002), and negatively related to the use of alcohol-based hand rub (2-month delay, coefficient -0·069, P = 0·0533). Alcohol-based hand rub is considered a modifiable factor and as such can be identified as a target for quality improvement programmes. Time-series analysis may provide a suitable methodology for identifying possible predictive variables that explain antibiotic use in healthcare settings. Future research should examine the relationship between infection control practices and antibiotic use, identify other infection control predictive factors for hospital antibiotic use, and evaluate the impact of enhancing different infection control practices on antibiotic use in a healthcare setting.

Atmospheric pressure, nonthermal plasma inactivation of MS2 bacteriophage: effect of oxygen concentration on virucidal activity

AimsThe main aim of this study was to determine the virucidal inactivation efficacy of an in-house-designed atmospheric pressure, nonthermal plasma jet operated at varying helium/oxygen feed gas concentrations against MS2 bacteriophage, widely employed as a convenient surrogate for human norovirus.

Methods and ResultsThe effect of variation of percentage oxygen concentration in the helium (He) carrier gas was studied and found to positively correlate with MS2 inactivation rate, indicating a role for reactive oxygen species (ROS) in viral inactivation. The inactivation rate constant increased with increasing oxygen concentrations up to 075% O-2. 3 log(10) (999%) reductions in MS2 viability were achieved after 3min of exposure to the plasma source operated in a helium/oxygen (9925%:075%) gas mixture, with >7 log(10) reduction after 9min exposure.

ConclusionsAtmospheric pressure, nonthermal plasmas may have utility in the rapid disinfection of virally contaminated surfaces for infection control applications.

Significance and Impact of StudyThe atmospheric pressure, nonthermal plasma jet employed in this study exhibits rapid virucidal activity against a norovirus surrogate virus, the MS2 bacteriophage, which is superior to previously published inactivation rates for chemical disinfectants.

Hand Washing: What is the solution?

Patients in perioperative healthcare settings are at risk of acquiring or developing infections because of the performance of invasive procedures. Serious life threatening infections can arise when micro-organisms are transmitted onto susceptible sites, such as: surgical wounds or intravascular cannulation sites. Infection control practices help to protect patients and healthcare providers by reducing and/or eliminating sources of infection.

Factors influencing acquisition of Burkholderia cepacia complex organisms in patients with cystic fibrosis

Burkholderia cepacia complex organisms are important transmissible pathogens found in cystic fibrosis (CF) patients. In recent years, the rates of cross-infection of epidemic strains have declined due to effective infection control efforts. However, cases of sporadic B. cepacia complex infection continue to occur in some centers. The acquisition pathways and clinical outcomes of sporadic B. cepacia complex infection are unclear. We sought to determine the patient clinical characteristics, outcomes, incidence, and genotypic relatedness for all cases of B. cepacia complex infection at two CF centers. We also sought to study the external conditions that influence the acquisition of infection. From 2001 to 2011, 67 individual organisms were cultured from the respiratory samples of 64 patients. Sixty-five percent of the patients were adults, in whom chronic infections were more common (68%) (P = 0.006). The incidence of B. cepacia complex infection increased by a mean of 12% (95% confidence interval [CI], 3 to 23%) per year. The rates of transplantation and death were similar in the incident cases who developed chronic infection compared to those in patients with chronic Pseudomonas aeruginosa infection. Multilocus sequence typing revealed 50 individual strains from 65 isolates. Overall, 85% of the patients were infected with unique strains, suggesting sporadic acquisition of infection. The yearly incidence of nonepidemic B. cepacia complex infection was positively correlated with the amount of rainfall in the two sites examined: subtropical Brisbane (r = 0.65, P = 0.031) and tropical Townsville (r = 0.82, P = 0.002). This study demonstrates that despite strict cohort segregation, new cases of unrelated B. cepacia complex infection continue to occur. These data also support an environmental origin of infection and suggest that climate conditions may be associated with the acquisition of B. cepacia complex infections.
