Evaluation of a Clostridium difficile infection management policy with clinical pharmacy and medical microbiology involvement at a major Canadian teaching hospital.

WHAT IS KNOWN AND OBJECTIVE: Clostridium difficile infection (CDI) represents a spectrum of disease and is a significant concern for healthcare institutions. Our study objective was to assess whether implementation of a regional CDI management policy with Clinical Pharmacy and Medical Microbiology and Infection Control involvement would lead to an improvement in concordance in prescribing practices to an evidence-based CDI disease severity assessment and pharmacological treatment algorithm. METHODS: Conducted at a tertiary care teaching hospital, this two-phase quality assurance study consisted of a baseline retrospective healthcare record review of patients with CDI prior to the implementation of a regional CDI management policy followed by a prospective evaluation post-implementation. RESULTS AND DISCUSSION: One hundred and forty-one CDI episodes in the pre-implementation group were compared to 283 episodes post-implementation. Overall treatment concordance to the CDI treatment algorithm was achieved in 48 of 141 cases (34%) pre-implementation compared with 136 of 283 cases (48·1%) post-implementation (P = 0·01). The median time to treatment with vancomycin was reduced from five days to one day (P < 0·01), with median length of hospital stay decreasing from 30 days to 21 days (P = 0·01) post-implementation. There was no difference in 30-day all-cause mortality. WHAT IS NEW AND CONCLUSION: A comprehensive approach with appropriate stakeholder involvement in the development of clinical pathways, education to healthcare workers and prospective audit with intervention and feedback can ensure patients diagnosed with CDI are optimally managed and prescribed the most appropriate therapy based on CDI disease severity.

Clean Hands for Life: results of a large, multicentre, multifaceted, social marketing hand-hygiene campaign.

A year-long multifaceted hand-hygiene campaign entitled Clean Hands for Life targeting individual, environmental and organisational factors that influence healthcare worker (HCW) hand-hygiene behaviour was implemented in 36 acute and long-term care facilities in Vancouver Coastal Health region. The campaign involved rotation of ten novel posters, two poster contests, and distribution of multiple promotional items. A social marketing approach was used to implement and monitor the effectiveness of the campaign. Evaluation included quality assurance surveys, staff surveys (baseline, mid- and post-campaign), and focus groups. A total of 141 poster contest submissions was received, 5452 staff surveys completed and 14 focus groups conducted. Overall knowledge of the importance of hand-hygiene and intention to clean hands was high at baseline. No significant differences were observed when mid- and post-campaign scores were compared to baseline. The majority (89.5%) of HCWs reported that they preferred soap and water over alcohol hand gel. A significant increase in the self-reported use of hand-hygiene products was observed particularly among HCWs not providing direct patient care. Barriers to hand-hygiene included inappropriate placement of sinks, traffic flow issues, inadequately stocked washrooms, workload and time constraints. Organisational support was visible throughout the campaign. The results showed that social marketing is an effective approach in engaging HCWs. Hand-hygiene campaigns that focus almost exclusively on increasing awareness among HCWs may not be as successful as multifaceted campaigns or campaigns that target identified barriers to hand-hygiene.

A cross-sectional study of SEN virus in liver transplant recipients.

A new DNA virus, referred to as SEN virus (SEN V), has been isolated and is associated with blood-product transfusion and possibly Non A to Non E hepatitis. We performed a cross-sectional analysis of SEN V in liver transplant recipients at our center. Polymerase chain reaction was used to test for 2 genotypes of SEN V (SEN V:C/H and SEN V:D) in 58 unselected patients. Comparisons were made between SEN V--positive and SEN V--negative groups in terms of age, time posttransplantation, indications for transplantation, serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels, and cytomegalovirus and Epstein-Barr virus status. Thirty of 58 transplant recipients (51.7%) were SEN V positive; 15.5% were positive for SEN V:C/H, 24.1% for SEN:D, and 12.1% for both strains. No significant differences were found based on primary indication for transplantation, including hepatitis C virus (HCV). Of the 14 of 21 patients with HCV seropositivity and HCV reinfection, 79% were positive for SEN V (P =.02). There was no difference in the proportion of patients with abnormal serum ALT and/or AST levels. A trend for the SEN V--positive group to have a greater mean ALT level (82 v 41 U/L; P =.067) was attributable to the subgroup with HCV recurrence because there was no difference in mean ALT levels (34.9 v 34.5 U/L; P =.968) in non--HCV-infected transplant recipients. Even in the subgroup (n = 14) with recurrent HCV, there was no statistically significant difference in mean ALT levels (140 v 105 U/L; P =.665). Age and cytomegalovirus or Epstein-Barr virus status were not significantly different between the 2 groups, but a significant difference in posttransplantation time was noted (16.8 v 32 months; P =.021). We conclude that SEN V is common among liver transplant recipients but does not appear to cause graft dysfunction as an isolated agent. There is a suggestion that SEN V may be associated with HCV recurrence, but we did not detect biochemical differences attributable to SEN V.
