Pressure injury prevention in adult critically ill patients: best practice implementation project

OBJECTIVE

This study assessed compliance with the best practices for pressure injury prevention among ICU patients at a tertiary hospital in São Paulo, Brazil.

INTRODUCTION

Intensive care patients are at high risk of developing a pressure injury; preventing this requires a best practice protocol.

METHOD

This best practice implementation project was conducted in a Brazilian tertiary hospital in three phases following the JBI Model of Evidence-based Healthcare. Ten criteria derived from the best available evidence were audited and monitored before and after best practice implementation.

RESULTS

The baseline and follow-up audits evaluated 28 patients at each step. A total of 448 h of care were analyzed using a monitoring camera and medical records. Compliance with all 10 audited criteria increased, with a 50% reduction in the prevalence of pressure injuries in intensive care. Of the 223 employees, 71% claimed to have some knowledge of pressure injury prevention, and 66% reported adequate adherence to prevention protocols.

CONCLUSION

The audit and feedback strategy improved compliance with the criteria. Future audits are needed to promote the sustainability of evidence-based practice.

Lived Experiences of Nursing Professionals Providing Care to COVID-19 Patients

Objective: To analyze nursing professionals’ reports on their lived experience in the care provided to hospitalized patients with COVID-19. Materials and Methods: This is an exploratory study using a qualitative analysis, which included twelve nurses and eight nursing technicians from a public hospital in Brazil, conducted between December 2020 and February 2021. The inclusion criteria were professionals who provided care to COVID-19 patients in emergency, intensive care, and inpatient units and who had at least one year of experience in the institution. The interviews were analyzed through content and similarity analysis that generated a similarity tree; the Reinert method was used for thematic categories. Results: Most participants were female, with a mean age of 34.15 years and 4.85 years of experience. From the analysis, the words ‘patient,’ ‘to stay,’ and ‘to find’ were the most frequent, and for the categories, they were “nursing professionals’ feelings regarding the pandemic,” “the nurses’ role and work with the multi-professional team in the care provided to patients with COVID-19,” “precautions with the care provided to patients with COVID-19,” and “nursing professionals’ concern that their family members may become ill during the pandemic.” Conclusions: The nursing staff is predominantly composed of females and, in their reports on the lived experience of providing care to patients with COVID-19, they pointed out that concern and fear were prevalent, with the family being one of the protective factors to withstand the risks of working against something novel that may result in death.

Factors associated with reoperation due to bleeding and outcomes after cardiac surgery: a prospective cohort study

OBJECTIVE

Identify the incidence and factors associated with reoperation due to bleeding in the postoperative of a cardiac surgery, in addition to the clinical outcomes of patients.

METHOD

Prospective cohort study, conducted in an Intensive Care Unit (ICU), with adult patients undergoing cardiac surgery. Patients diagnosed with coagulopathies were excluded. The patients were followed up from hospitalization to hospital discharge.

RESULTS

A total of 682 patients were included, and the incidence of reoperation was 3.4%. The factors associated with reoperation were history of renal failure (p = 0.005), previous use of anticoagulant (p = 0.036), higher intraoperative heart rate (p = 0.015), need for transfusion of blood component during intraoperative (p = 0.040), and higher SAPS 3 score (p < 0.001). The outcomes associated with reoperation were stroke and cardiac arrest.

CONCLUSÃO

Reoperation was an event associated with greater severity, organic dysfunction, and worse clinical outcomes, but there was no difference in mortality between the groups.

Factors Associated With the Illness of Nursing Professionals Caused by COVID-19 in Three University Hospitals in Brazil

Background

The coronavirus disease 2019 (COVID-19) pandemic has demonstrated the importance of implementing strategic management that prioritizes the safety of frontline nurse professionals. In this sense, this research was aimed at identifying factors associated with the illness of nursing professionals caused by COVID-19 according to socio-demographic, clinical, and labor variables.

Methods

A cross-sectional study was conducted in three Brazilian university hospitals with 859 nursing professionals, which include nurses, technicians, and nursing assistants, between November 2020 and February 2021. We present data using absolute and relative frequency. We used Chi-square test for hypothesis testing and multiple logistic regression for predictive analysis and chances of occurrence.

Results

The rate of nursing professionals affected by COVID-19 was 41.8%, and the factors associated with contamination were the number of people in the same household with COVID-19 and obesity. Being a nurse was a protective factor when the entire nursing team was considered. The model is significant, and its variables represent 56.61% of the occurrence of COVID-19 in nursing professionals.

Conclusion

Obesity and living in the same household as other people affected by COVID-19 increases the risk of contamination by this new coronavirus.

Impacto do controle glicêmico intensivo na lesão renal aguda: ensaio clínico randomizado

Resumo Objetivo Avaliar o impacto do controle glicêmico intensivo na redução da incidência de lesão renal aguda em pacientes adultos submetidos à cirurgia cardíaca. Métodos Ensaio clínico randomizado que avaliou 95 pacientes submetidos a duas estratégias de controle glicêmico. Os pacientes foram randomizados para o grupo intervenção (GI), com a meta de manutenção da glicemia pós-operatória entre 90 e 110 mg/dl. Nos pacientes alocados no grupo convencional (GC) o objetivo era a manutenção da glicemia entre 140 e 180 mg/dl. O ajuste da dose de insulina foi baseado em medições de glicose no sangue arterial não diluído, em intervalos de uma hora por meio de um sistema de monitoramento de glicose e beta-cetona no sangue. Resultados A incidência de LRA foi de 53,7% (KDIGO estágios 1, 2 ou 3). Não houve diferença significante entre os grupos quanto ao desfecho primário (p=0,294). Entretanto, observou-se maior frequência de recuperação da função renal (p=0,010), na alta da UTI (p=0,028) e alta hospitalar (p=0,048) entre os pacientes submetidos ao controle glicêmico convencional. A utilização do controle glicêmico intensivo esteve associada com maior tempo de permanência na UTI (p=0,031). O número de episódios de hipoglicemia foi semelhante nos dois grupos (1,6 ± 0,9 vs. 1,3 ± 0,6, p=0,731), demonstrando a segurança das estratégias utilizadas. Conclusão Não se observou o impacto do controle glicêmico intensivo na redução da incidência de lesão renal aguda. Em contrapartida, os pacientes tratados no GC apresentaram maior frequência de recuperação da função renal.

Management of peripherally inserted central catheter use in an intensive care unit of a teaching hospital in Brazil: a best practice implementation project

OBJECTIVE

This project aimed to promote evidence-based practice in the management of peripherally inserted central venous catheters (PICCs) in pediatric and adult patients in an intensive care unit (ICU).

INTRODUCTION

A PICC provides secure vascular access to medication, blood and nutrition administration. However, their use in the ICU is limited. Gaps in training and education in the use of these catheters are barriers to improving practice and safety.

METHODS

The project was conducted in an ICU of a cardiology teaching hospital in São Paulo, Brazil. The Joanna Briggs Institute Practical Application of Clinical Evidence System and Getting Research into Practice audit tools were used. A baseline audit of the management of PICCs in pediatric and adult patients was conducted, with a sample size of 22 patients and 180 nursing staff. After an educational program, a follow-up audit involving 14 patients and 180 nursing staff was conducted using the same audit criteria.

RESULTS

The baseline audit indicated that PICC management concerning flushing had poor compliance of 2-20%. The results of the criteria related to the change in administration sets, including secondary sets and add-on devices, had better results, with moderate (65%) to high (100%) compliance. The follow-up audit showed improvement in all 10 criteria. Criteria related to flushing achieved 83% to 89% compliance; criteria related to dressing and change of administration sets achieved 100% compliance.

CONCLUSIONS

Increased compliance with evidence-based best practices was achieved in all assessed audit criteria. The criteria that reached the highest compliance with best practice recommendations were related to the prevention of bloodstream infection and loss of the PICC due to obstruction. Future audits are planned to ensure sustainability.

ENSINO DAS HABILIDADES DO PENSAMENTO CRÍTICO POR MEIO DE PROBLEM BASED LEARNING

RESUMO Objetivo: analisar comparativamente a percepção de estudantes de enfermagem, em duas turmas, sobre o ensino implícito do pensamento crítico em um curso de Suporte Básico de Vida. Método: intervenção educativa, com abordagem qualitativa, fundamentada na teoria histórico-cultural. Participaram do estudo 102 estudantes, sendo 52 no grupo intervenção, que foram ensinados por meio da metodologia Problem Based Learning associada às questões norteadoras, e 50 no grupo controle, ensinados apenas com Problem Based Learning. Os dados foram coletados de 12 a 30 de novembro de 2015, na Universidade Federal de Viçosa, através de questionário sociodemográfico, instrumento avaliativo e entrevistas semiestruturadas. O instrumento avaliativo e as entrevistas foram explorados pela análise de conteúdo de Bardin. Resultados: o curso mobilizou habilidades de pensamento crítico nos estudantes de ambos os grupos. Contudo, no grupo intervenção, expuseram com mais clareza percepções sobre as características de um pensador crítico. No grupo controle, ao qual foi aplicada apenas a metodologia Problem Based Learning, os estudantes mencionaram aquisição de habilidades técnicas. No grupo intervenção, ao qual foi aplicada a metodologia Problem Based Learning associada às questões norteadoras, além das habilidades técnicas, os estudantes relataram habilidades de um pensador crítico. Conclusão: a análise comparativa permite concluir que metodologias de ensino mobilizadoras do pensamento crítico se tornam mediadoras no desenvolvimento e aprimoramento das funções mentais superiores no ensino, abarcando capacidades cognitivas e metacognitivas. O estudo representa contribuição e avanço no âmbito do ensino de enfermagem, considerando que as questões somam-se às tecnologias de educação em saúde.

Effectiveness of rifampicin chemoprophylaxis in preventing leprosy in patient contacts: a systematic review of quantitative and qualitative evidence

BACKGROUND

Individuals in contact with patients who have leprosy have an increased risk of disease exposure, which reinforces the need for chemoprophylactic measures, such as the use of rifampicin.

OBJECTIVES

The objective of the review was to synthesize the best available evidence regarding the effectiveness of rifampicin chemoprophylaxis for contacts with patients with leprosy, and to synthesize the best available evidence on the experience and acceptability of rifampicin chemoprophylaxis as reported by the contacts and health professionals involved in the treatment of leprosy or Hansen's disease.

INCLUSION CRITERIA TYPES OF PARTICIPANTS

In the quantitative component, individuals in contact with leprosy patients were included. In the qualitative component, in addition to contacts, health professionals who were in the practice of treating leprosy were included.

TYPES OF INTERVENTION(S)/PHENOMENA OF INTEREST

The quantitative component considered as an intervention rifampicin at any dose, frequency and mode of administration, and rifampicin combination regimens.The qualitative component considered as phenomena of interest the experience and acceptability of rifampicin chemoprophylaxis.

TYPES OF STUDIES

The quantitative component considered experimental and observational studies whereas the qualitative component considered studies that focused on qualitative data, including but not limited to, designs such as phenomenology, grounded theory, ethnography and action-research.

OUTCOMES

The quantitative component considered studies that reported on outcomes such as the development of clinical leprosy in the contacts of patients who had leprosy, incidence rates, adverse effects and safety/harmful effects of the intervention.

SEARCH STRATEGY

A three-step strategy for published and unpublished literature was used. The search for published studies included: PubMed, Cumulative Index to Nursing and Allied Health Literature, Cochrane Library, Scopus, Web of Science, National Institute for Health and Clinical Excellence, Latin American and Caribbean Health Sciences Literature; and Google Scholar and EVIPnet for unpublished studies. Studies published from the time of the respective database inception to January 2016 in English, Spanish, Portuguese, Japanese and Chinese were considered.

METHODOLOGICAL QUALITY

Two reviewers independently assessed the studies for methodological quality using standardized critical appraisal instruments from the Joanna Briggs Institute.

DATA EXTRACTION

Standardized data extraction tools developed by the Joanna Briggs Institute were used to extract quantitative and qualitative data from papers included in the review.

DATA SYNTHESIS

Due to clinical and methodological heterogeneity in the interventions of the included studies, no statistical meta-analysis was possible. Quantitative and qualitative research findings are presented in narrative form.

RESULTS

Following critical appraisal, eight studies were included in this review, seven quantitative and one qualitative. The reduction in incidence of leprosy, using one dose of rifampicin in the first two years, was 56.5%; in the follow up period of one to four years, the reduction was 34.9%. The combination of rifampicin and the Bacillus Calmette-Guérin vaccine showed a preventative effect of 80% against the disease. The only controlled clinical trial using two doses of rifampicin was community-based and did not indicate effectiveness of the intervention. The qualitative findings showed social acceptability of rifampicin.

CONCLUSIONS

Chemoprophylaxis with one dose of rifampicin is found to be effective in preventing contacts of leprosy patients from contracting the disease. Also, there is indication that this strategy is socially accepted.

Objective:

to analyze the concept of critical thinking (CT) in Rodger's evolutionary perspective.

Method:

documentary research undertaken in the Cinahl, Lilacs, Bdenf and Dedalus databases, using the keywords of 'critical thinking' and 'Nursing', without limitation based on year of publication. The data were analyzed in accordance with the stages of Rodger's conceptual model. The following were included: books and articles in full, published in Portuguese, English or Spanish, which addressed CT in the teaching and practice of Nursing; articles which did not address aspects related to the concept of CT were excluded.

Results:

the sample was made up of 42 works. As a substitute term, emphasis is placed on 'analytical thinking', and, as a related factor, decision-making. In order, the most frequent preceding and consequent attributes were: ability to analyze, training of the student nurse, and clinical decision-making. As the implications of CT, emphasis is placed on achieving effective results in care for the patient, family and community.

Conclusion:

CT is a cognitive skill which involves analysis, logical reasoning and clinical judgment, geared towards the resolution of problems, and standing out in the training and practice of the nurse with a view to accurate clinical decision-making and the achieving of effective results.

Desfechos clínicos de pacientes pediátricos tratados com oxigenação por membrana extracorpórea

Resumo Objetivo Identificar os fatores relacionados à mortalidade e avaliar a sobrevida de pacientes pediátricos tratados com oxigenação por membrana extracorpórea. Métodos Estudo de coorte retrospectivo, que incluiu pacientes pediátricos que utilizaram o dispositivo nos últimos cinco anos. Os grupos foram divididos com base naqueles que sobreviveram ou não após a terapia. Para avaliar os fatores preditivos de morte, foi utilizada análise multivariada com regressão logística e, para a sobrevida, o método de Kaplan-Meier e Log-Rank. Resultados A fração de ejeção do ventrículo esquerdo era maior no grupo de sobreviventes (74%+14,6% vs 56,2% + 22%, p=0,038) e o número de pacientes que necessitaram de diálise foi maior no grupo de não sobreviventes (52,4% vs. 12,5%, p=0,039), sendo a sobrevida significativamente menor neste grupo (log-rank=0,020). Conclusão Disfunção ventricular prévia, evidenciada pela fração de ejeção do ventrículo esquerdo <55%, e necessidade de terapia de substituição renal concomitante aumentaram o risco de morte.

Effectiveness of teaching strategies on the development of critical thinking in undergraduate nursing students: a meta-analysis

Abstract OBJECTIVE To evaluate the effectiveness of teaching strategies used for development of critical thinking (CT) in undergraduate nursing students. METHOD Systematic review with meta-analysis based on the recommendations of the Joanna Briggs Institute . Searches were conducted in the following databases: PubMed, CINAHL, EMBASE, Web of Science, SCOPUS, LILACS, Cochrane CENTRAL, PsycINFO, ERIC, and a database of theses from four continents. The initial selection and evaluation of studies and assessment of methodological quality was performed by two reviewers independently. RESULTS Twelve randomized clinical trials were included in the study. In the meta-analysis of the four studies included that evaluated the strategy of problem-based learning (PBL), compared to lectures, the effectiveness of PBL was demonstrated with statistical significance (SMD = 0.21 and 95% CI = 0.01 to 0.42; p = 0.0434) for the development of CT in undergraduate nursing students, and the studies were homogeneous (chi-square = 6.10, p = 0.106). CONCLUSION The effectiveness of PBL was demonstrated in the increase of overall CT scores. Further studies need to be conducted in order to develop, implement and evaluate teaching strategies that are guided in high methodological rigor, and supported in theoretical models of teaching and learning.

RESUMO Objetivo Identificar os fatores associados à carga de trabalho de enfermagem no cuidado a pacientes no pós-operatório de cirurgia cardíaca. Método Estudo de coorte prospectivo, conduzido com 187 pacientes da Unidade de Terapia Intensiva Cirúrgica (UTI) do Instituto do Coração. Os dados foram coletados nas primeiras 24 e 72 horas do paciente na UTI. A variável dependente foi a carga de trabalho calculada por meio do Nursing Activities Score (NAS) e as independentes foram de natureza demográfico-clínicas e escores de morbimortalidade. Para análise dos dados utilizou-se os testes de Wilcoxon-Mann-Whitney e de correlação de Spearman, e a regressão linear com modelo de efeitos mistos. Resultados A maioria dos pacientes era do sexo masculino (59,4%), com média de idade de 61 anos (±12,7) e 43,9% desenvolveram algum tipo de complicação no pós-operatório. Nas 24 horas, a carga de trabalho foi de 82,4% (±3,4) e foi de 58,1% (±3,4) nas 72 horas. Os fatores associados ao aumento do NAS foram: tempo de internação do paciente na UTI (p=0,036) e a presença de complicações (p<0,001). Conclusão A gravidade do paciente nas 24 horas, em oposição a inúmeros estudos, não influenciou no aumento da carga de trabalho, a qual se mostrou associada ao tempo de internação e às complicações.

[Strategies for prevention of acute kidney injury in cardiac surgery: an integrative review]

Acute kidney injury is a common complication after cardiac surgery and is associated with increased morbidity and mortality and increased length of stay in the intensive care unit. Considering the high prevalence of acute kidney injury and its association with worsened prognosis, the development of strategies for renal protection in hospitals is essential to reduce the associated high morbidity and mortality, especially for patients at high risk of developing acute kidney injury, such as patients who undergo cardiac surgery. This integrative review sought to assess the evidence available in the literature regarding the most effective interventions for the prevention of acute kidney injury in patients undergoing cardiac surgery. To select the articles, we used the CINAHL and MedLine databases. The sample of this review consisted of 16 articles. After analyzing the articles included in the review, the results of the studies showed that only hydration with saline has noteworthy results in the prevention of acute kidney injury. The other strategies are controversial and require further research to prove their effectiveness.
