Assessing staff knowledge about Clostridium difficile diarrhoea

Nurses' knowledge, practices and perceptions regarding Clostridioides difficile: Survey results

BACKGROUND

Clostridioides difficile infection (CDI) can cause patients debilitating symptoms, places additional demands on nurses' and midwives' and is increasingly prevalent. Understanding the knowledge base of nurses caring for patients with CDI may contribute to improving care practices.

METHODS

A cross-sectional anonymous survey across our Hospital and Health Services was conducted. Descriptive statistics and thematic analysis techniques were used to analyse, summarise, and report data.

RESULTS

A total of 198 completed surveys by nurses were included in the analysis. Most respondents (73.2%) could not recall having any recent CDI education. Nearly all agreed that CDI is an important infection control issue (80. 8%), and that CDI education was important (94.9%). Knowledge of the potentially fatal outcome of CDI was not well known with only 53% responding correctly to this question. Respondents were confident in fundamental infection control precautions of patient placement (93.4%) and environmental cleaning (86.4%). Knowledge of the microbiological aspects of CDI were less well known. The impact to workload and the additional burden of caring for patients with CDI was evident in the overwhelming response (83%) to the two open-ended questions about what makes it "easy" and what make it "hard" to implement infection control strategies for CDI patients.

CONCLUSION

Respondents identified many factors that could contribute to less-than optimal care and management of inpatients with CDI, and identified some solutions that would facilitate the provision of best practice. An educational intervention, with emphasis on the areas of greatest knowledge deficits, has been developed.

Understanding factors that impact on health care professionals' risk perceptions and responses toward Clostridium difficile and meticillin-resistant Staphylococcus aureus: a structured literature review

BACKGROUND

Clostridium difficile is the most common health care-associated infection. Despite considerable efforts to prevent and manage C difficile, poor clinical practice and nonadherence to policy continues to compromise patient safety. Risk perception research is essential in gaining understanding about how health care professionals respond.

METHODS

A structured literature review examined empirical evidence regarding health care professionals' risk perceptions and responses toward C difficile. Because of limited evidence available, the review was extended to include other health care-associated infections. Only studies related to methicillin-resistant Staphylococcus aureus (MRSA) could be identified.

RESULTS

Eleven studies were included. Four were specific to C difficile and 7 to MRSA. All studies found that technical understanding of C difficile was poor and that staff were concerned about risks to patients and themselves. Technical understanding for MRSA, however, was good, and staff were less concerned about their own health. Information provision was perceived to be inadequate and untrustworthy, which included the media. Practice in most studies was poor.

CONCLUSION

There is a need to build on the efforts of risk perception research from other disciplines to understand how health care professionals think and make decisions about C difficile. This can help inform the development of effective management and communication strategies to maximize the quality of care provided.

Overview of strategies for overcoming the challenge of antimicrobial resistance

The discovery of penicillin undoubtedly transformed the management of life-threatening bacterial infections. However, a less comfortable aspect of the antibiotic revolution was that within 10 years, over 80% of patients with acute bronchitis were receiving antibiotics without any evidence of clinical benefit. Antibiotic use inevitably causes collateral damage to the normal human flora and increases the risk of infection with antibiotic-resistant bacteria and Clostridium difficile. The twin aims of antibiotic stewardship are first to ensure effective treatment for patients with bacterial infection and second to provide convincing evidence and information to educate and support professionals and patients to reduce unnecessary use and minimize collateral damage. We review evidence of progress with these aims in Europe and nationally in Scotland.

Knowledge of Clostridium difficile infection among UK health-care workers: development of a knowledge assessment tool

Doctors’ knowledge provides the basis to support good practice in infection prevention and control. However, there exists a paucity of validated knowledge assessment tools that can be reliably employed to identify poor knowledge levels of Clostridium difficile infection (CDI) within populations of doctors, preventing the effective identification of knowledge deficiencies and focused targeting of educational interventions. Here, we describe a development process to validate a novel CDI knowledge assessment tool for doctors. Two previously published CDI knowledge questionnaires were amalgamated to produce a combined questionnaire. Content was further evaluated by a panel of CDI experts, producing the ‘Lothian’ questionnaire. These questionnaires were tested in control populations comprising either infection control nurse (ICN) specialists or non-clinically trained individuals, and a cohort of medical staff. We compared the efficacy of the ‘Lothian’ questionnaire against that of previous questionnaire reports. We found that all of the questionnaires studied significantly discriminated between non-clinical and clinical populations (ICNs and medical staff) ( P < 0.001) and had similar levels of sensitivity and specificity in discrimination between these targeted populations. This study describes the development of a robust CDI knowledge assessment tool that can be used to evaluate knowledge levels among doctors, compare populations and assist the targeting of educational interventions and plot trends following such interventions.
