Putting Evidence Into Practice: Prevention of Infection

Development and psychometric pilot-testing of a questionnaire for the evaluation of satisfaction with continuing education in infection control nurses

Satisfaction with continuing education can be defined as positive attitudes towards educational programs, which has potential to strengthen learning outcomes. A multi-dimensional construct may enhance continuing education program evaluation processes. The objective is to describe the development and psychometric testing of the 'affective - behavioral - cognitive - satisfaction questionnaire' (ABC-SAT) for assessing participants' satisfaction with a continuing education program for nurses in infection control. The multi-staged development of a satisfaction questionnaire comprised of three subscales. The pilot tool was administered to a nationwide sample of 126 infection control nurses to assess satisfaction after participating in a continuing education program. Satisfaction scores were calculated and psychometric testing was performed to determine reliability, using Cronbach's alpha, face validity, objectivity, and economy. A principle component analysis using varimax rotation and Kaiser normalization was performed. The analysis led to a three-factor solution of the questionnaire with 11 items, explaining 61.4% of the variance. Internal consistency of three scales using Cronbach's alpha was 0.83, 0.60, and 0.66, respectively. Selectivity coefficients varied between 0.39 and 0.70. Participants needed approximately three minutes to complete the questionnaire. Initial findings refer to a satisfying scale structure and internal consistency of the 3-dimensional ABC-SAT questionnaire. Further research is required to confirm the questionnaires' psychometric properties.

The assessment and management of chemotherapy-related toxicities in patients with breast cancer, colorectal cancer, and Hodgkin's and non-Hodgkin's lymphomas: A scoping review

PURPOSE

The purpose of the eSMART (Electronic Symptom Management using the Advanced Symptom Management System (ASyMS) Remote Technology) study is to evaluate the use of mobile phone technology to manage chemotherapy-related toxicities (CRTs) in people with breast cancer (BC), colorectal cancer (CRC), Hodgkin's lymphoma (HL), and non-Hodgkin lymphoma (NHL)) across multiple European sites. One key objective was to review the published and grey literature on assessment and management of CRTs among patients receiving primary chemotherapy for BC, CRC, HL, and NHL to ensure that ASyMS remained evidence-based and reflected current and local practice.

METHODS

Three electronic databases were searched for English papers, with abstracts available from 01/01/2004-05/04/2014. For the grey literature, relevant clinical practice guidelines (CPGs)/evidence-based resources (EBRs) from the main international cancer organisations were reviewed as were symptom management (SM) protocols from the sites.

RESULTS

After full-text screening, 27 publications were included. The majority (n = 14) addressed fatigue and focused on BC patients. Relevant CPGs/EBRs were found for fatigue (n = 4), nausea/vomiting (n = 5), mucositis (n = 4), peripheral neuropathy (n = 3), diarrhoea (n = 2), constipation (n = 2), febrile neutropenia/infection (n = 7), palmar plantar erythrodysesthesia (PPE) (n = 1), and pain (n = 4). SM protocols were provided by >40% of the clinical sites.

CONCLUSIONS

A need exists for empirical research on SM for PPE, diarrhoea, and constipation. Research is needed on the efficacy of self-care strategies in patients with BC, CRC, HL, and NHL. In general, consistency exists across CPGs/EBRs and local guidelines on the assessment and management of common CRTs.

How can we help haematological cancer survivors cope with the changes they experience as a result of their cancer?

Haematological cancer often necessitates that individuals make significant lifestyle and behaviour changes to protect themselves against infections. It is essential that haematological cancer survivors receive the support and information they require to adjust to such changes. This cross-sectional survey of 259 haematological cancer survivors found that over two thirds of haematological cancer survivors would like to receive more detailed information or help with: diet and nutrition that takes into account their diagnosis and treatment, how to manage the symptoms from the cancer and/or treatment, signs and symptoms to be aware of that may indicate a possible infection and appropriate exercise. Over a third of survivors reported that they had to make changes to reduce their chance of infection, with social restriction the most commonly reported area of change survivors made. Improving communication and access to care and providing additional emotional support may assist survivors in making these additional changes. Healthcare providers should use this information to better support haematological cancer survivors in dealing with the effects haematological cancer has on their life.

Anti-infective prophylaxis in pediatric patients with acute myeloid leukemia

Pediatric patients undergoing treatment for acute myeloid leukemia (AML) are at high risk for infectious complications, predominantly due to Gram-negative bacteria, viridans group streptococci and fungal pathogens. In order to prevent infections in these patients, most institutions have implemented a number of non-pharmacological approaches to supportive care. In addition, antibiotic prophylaxis reduces bacterial infection, but may increase the emergence of resistance. Antifungal prophylaxis is generally recommended for children with AML. Whereas the use of hematopoietic growth factors has not resulted in improved survival, the efficacy of prophylactic granulocyte transfusions has to be determined.

Neutropenia Precautions for Children Receiving Chemotherapy or Stem Cell Transplantation for Cancer

Infections in children and adolescents with cancer are a significant cause of morbidity and mortality, especially in those receiving chemotherapy who are neutropenic and/or immunocompromised. The aim of this article is to review existing evidence in order to provide a practice recommendation to prevent or minimize infections in neutropenic and/or immunocompromised patients receiving chemotherapy and/or stem cell transplant. Systematic reviews were undertaken and research was graded according to the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) criteria. A variety of interventions are implemented to reduce infections in the neutropenic and/or immunocompromised population; however, few are supported by research evidence. Existing literature should continue to be reviewed to further identify interventions that can influence positive patient outcomes and provide opportunities for individuals in the medical field to work together to improve clinical care.

SIOP PODC: recommendations for supportive care of children with cancer in a low-income setting

These supportive care recommendations were prepared to guide doctors who practice in areas with significantly limited resources but who have sufficient infrastructure and training to treat children with cancer with curative intent. The success of any cancer treatment regimen depends largely on the availability and quality of supportive care and this also determines the intensity of treatment that can be delivered. We present practical recommendations on how to prevent infections, general nursing care, management of febrile neutropenia, nutritional assessment and support, treatment of co-infections and the social support to help prevent failure to complete treatment in resource poor settings.

Variations in non-pharmacological anti-infective measures in childhood leukemia--results of an international survey

BACKGROUND

Standardization in clinical practice may lead to improved outcomes. Unfortunately, little is known about the variability of non-pharmacological anti-infective measures in children with cancer.

DESIGN AND METHODS

A web-based survey assessed institutional recommendations regarding restrictions of social contacts, pets and food and instructions on wearing face masks in public for children with standard- risk acute lymphoblastic leukemia and acute myeloid leukemia during intensive chemotherapy.

RESULTS

A total of 336 institutions in 27 countries responded to the survey (range, 1-76 institutions per country; overall response rate 61%). Most institutions recommend that patients with acute myeloid leukemia avoid indoor public places and daycare, kindergarten and school, whereas recommendations for patients with acute lymphoblastic leukemia differ considerably by institution. In terms of restrictions related to pets, there was a wide variability between institutions for both acute lymphoblastic and acute myeloid leukemia patients. Most, but not all institutions do not allow children with either acute lymphoblastic or acute myeloid leukemia to eat raw meat, raw seafood or unpasteurized milk. Whereas most institutions do not routinely recommend that patients with acute lymphoblastic leukemia wear face masks in public, advice on this matter varies for patients with acute myeloid leukemia.

CONCLUSIONS

The survey demonstrates that there is a wide variation in recommendations on non-pharmacological anti-infective measures between different institutions, countries and continents. This information may be used to encourage harmonization of supportive care practices and future clinical trials.

Evaluation of infection control advice for patients at risk of chemotherapy-induced neutropenia in 2 pediatric oncology centers: Cape Town, South Africa, and Newcastle-Upon-Tyne, UK

Childhood cancers are treated with myelotoxic chemotherapy. Resultant neutropenia can lead to life-threatening infections. There is no consistent guidance on infection control precautions for neutropenic patients who are not yet febrile or infected. Although it is not possible to eradicate infection risk, it is conceivable that the risk could be reduced by effective infection prevention. This study compared infection control measures advised to pediatric and adolescent oncology patients receiving chemotherapy in 2 centers (Cape Town, South Africa, and Newcastle, UK). Prospective, observational, cross-sectional surveys of staff and patients/parents were undertaken using standardized, study-specific questionnaires. Seventy-eight staff and 56 patients/parents participated. Precautions advised in Newcastle were significantly different to Cape Town (all P < .05), except both agreed inpatient isolation was unnecessary. Over 40% of patients/parents felt isolation was important (P < .01). In Cape Town, staff and patients had similar views. In Newcastle, patients/parents had stricter opinions on particular precautions than staff, for example, attending school, playing outside and avoiding busy places (P < .01). Patient/parent responses were similar between centers. Over 90% of staff felt advising patients/parents about hand washing was important. Currently infection prevention advice is inconsistent. Further research is needed to elucidate effective guidance for infection prevention in pediatric neutropenic patients.

Infection prevention measures used in hematopoietic stem cell transplantation: evidences for practice

This integrative review aimed to identify and assess evidence available about the use of high-efficiency air filters, protective isolation and masks for infection prevention in patients submitted to hematopoietic stem cell transplantation during hospitalization. LILACS, PUBMED, CINAHL, EMBASE and the Cochrane Library were used to select the articles. Of the 1023 identified publications, 15 were sampled. The use of HEPA filters is recommended for patients submitted to allogeneic transplantation during the neutropenia period. The level of evidence of protective isolation is weak (VI) and the studies evaluated did not recommend its use. No studies with strong evidence (I and II) were evaluated that justify the use of masks, while Centers for Disease Control and Prevention recommendations should be followed regarding the use of special respirators by immunocompromised patients. The evidenced data can support decision making with a view to nursing care.

Tendências da produção do conhecimento de enfermagem no controle de infecção em oncologia

Os clientes com câncer apresentam complicações significativas de morbi-mortalidade relacionadas à infecção. Esta revisão integrativa tem como objetivo analisar a produção científica da enfermagem acerca do controle de infecções nos clientes com câncer. A busca dos 37 artigos incluídos foi por meio eletrônico em bases de dados, no período de 2002 a 2009. Os dados foram analisados na perspectiva da Metodologia de Categorização Epistemológica para a Pesquisa na Enfermagem. Os resultados indicam que a produção é internacional, mais setorizada na área da oncologia clínica, com ênfase nos clientes como sujeitos das investigações, tendência exógena da origem da infecção e prevalência de artigos de revisão de literatura. Conclui-se que a produção do conhecimento no controle de infecção é prioridade no cenário nacional, as ações devem ser baseadas numa visão sistêmica, considerando a complexidade que envolve os profissionais na prestação do cuidado de enfermagem.

Physiological aging in older adults with cancer: implications for treatment decision making and toxicity management

Because the risk of cancer increases with age, the growth of the aging population will lead to a larger number of older adults with cancer. Standard cancer treatments can be safe and effective in older adults and result in improved survival and enhanced quality of life. Because physiological decline varies among older adults, cancer treatment requires an individualized approach. Consideration of physiological age, rather than chronological age alone, is required to guide treatment decision making and prevent and manage treatment toxicities and other complications. This article examines the impact of physiological aging on treatment decision making and toxicity management in older adults with cancer.

Prevention of Infection in Patients With Cancer

OBJECTIVES

To provide clinicians with the most reliable, updated evidence to support clinical decision-making and improve outcomes for patients with cancer who are at increased risk for infection.

DATA SOURCES

Review of two evidence-based summaries of prevention of infection interventions published by the Oncology Nursing Society; MEDLINE and guidelines.gov literature review.

CONCLUSION

Handwashing is the most important intervention to prevent infection in patients with cancer. Guidelines-based intravascular catheter care and preventive activities can reduce infection incidence in this vulnerable patient population. Understanding risk factors for aggressive pathogens can help identify patients for rapid surveillance and isolation procedures. Additional multi-site research is required in oncology settings to recommend recent interventions for practice.

IMPLICATIONS FOR NURSING PRACTICE

Oncology nurses should assess their adherence to evidence-based guidelines on infection prevention. Outcomes are optimized when clinicians identify high-risk patients and provide scientifically supported interventions.
