Clostridium difficile infection objectives updated

NHS Improvement | Clostridium difficile infection objectives for NHS organisations in 2018/19, guidance on sanction implementation and notification of changes to case attribution definitions from 2019| March 2018

NHS Improvement have updated the objectives on Clostridium difficile infection (CDI). This document outlines the objectives for acute trusts and clinical commissioning groups to make continuous improvement in Clostridium difficile infection (CDI) care.

They objectives are updated every April. The updated objectives are available from NHS Improvement 

Clostridium difficile infection assessment tool and action plan guidance can be accessed from NHS England

Is pulsed the answer to treatment of Clostridium difficile infection?

Antibiotic treatment of Clostridium difficile infection has been plagued by high rates of recurrent diarrhoea attributed to C difficile and requiring retreatment, often repeatedly. In the latest edition of The Lancet Infectious Diseases, Benoit Guery and colleagues describe a novel dosing regimen for fidaxomicin in which the standard 200 mg, 20-dose, 10-day regimen is extended (the EXTEND study) by giving 200 mg twice daily for the first 5 days, followed by 200 mg every-other-day for an additional 20 days. The comparator regimen was standard-dose vancomycin (125 mg four times daily for 10 days), which is the same comparator dose that was used in two phase 3 licensing trials of standard-dose fidaxomicin (200 mg twice daily for 10 days).

Assessing the burden of Clostridium difficile infections for hospitals

Nosocomial infections place a heavy burden on the healthcare system. However, quantifying the burden raises many questions, ranging from the way to accurately estimate the extra length of stay at hospital to defining and costing the preventative methods among the different care providers | Journal of Hospital Infection

A total of 52 episodes were screened during the study period. The estimated mean cost of CDI was approximately €23,909 (SD = 17,458) for an extended length of hospital stay (N = 27). In the case of a reduced length of the hospital stay (N = 25), the mean cost was approximately € –14,697 (SD = 16,936), which represents net savings for the hospitals. The main cost/savings driver was the productivity losses/gains resulting from the nosocomial infection. A sensitivity analysis showed that the main factor explaining the amount of costs or savings due to nosocomial infections was the length of the hospital stay.

Conclusion: We discuss the notion of productivity gains in the case of deaths as a factor revealing the incompleteness of the payment systems. We then discuss the methodological issues associated with the statistical method used to control for temporality bias.

Can improving patient hand hygiene impact Clostridium difficile infection events at an academic medical center?

Highlights: 

  • An educational intervention study was completed to improve patient hand hygiene opportunities for patients at a large academic medical center.
  • After the intervention, it was possible to study the effects of improved patient hand hygiene on health care facility–onset Clostridium difficile infection events.
  • C difficile infection events decreased significantly (P ≤ .05) for 6 months after the intervention.
  • Patient hand hygiene may be an underused prevention measure for C difficile disease; successful implementation requires staff to engage the patient with opportunities, reminders, and encouragement to keep their hands clean

Antimicrobial stewardship program and Clostridium difficile

Institutional antimicrobial stewardship programs seek to decrease the occurrence of C difficile by implementing strategies to address antibiotic usage; however, optimal structure and strategies for accomplishing this remain largely unknown | American Journal of Infection Control

Highlights: 

  • More hospitals with non-better Clostridium difficile rank used prospective audit and feedback.
  • More better C difficile rank hospitals used a preauthorization strategy.
  • More better C difficile rank hospitals restricted more high-risk antibiotics.

Tobacco use as a screener for Clostridium difficile infection outcomes

A retrospective cohort study to evaluate the utility of self-reported tobacco use for developing a clinical prediction rule for poor outcomes of Clostridium difficile infection | Journal of Hospital Infection

We found that patients with any history of smoking were significantly less likely than never smokers to be cured of their infection within two weeks. Disease recurrence, readmission within thirty days, death before treatment completion, and the severity of Clostridium difficile infection were not associated with smoking status.

Are alcohol-based dispensers fomites for C difficile?

The purpose of this study was to evaluate alcohol-based dispensers as potential fomites for Clostridium difficile | American Journal of Infection Control

11694-2

A convenience sample of 120 alcohol-based dispensers was evaluated for the presence of C difficile either by culture or polymerase chain reaction for C difficile toxin. The results demonstrated that C difficile was not cultured, and C difficile toxin was not detected using polymerase chain reaction; however, gram-positive rods, Clostridium perfringens, Pantoea agglomerans, coagulase-negative Staphylococcus, Peptostreptococcus, Bacillus spp, and microaerophilic Streptococcus were present within the overflow basins of the alcohol-based dispensers.
