Using targeted solution tools as an initiative to improve hand hygiene: challenges and lessons learned.

The Joint Commission Centre for Transforming Healthcare's Web-based Targeted Solutions Tool (TST) for improving hand hygiene was implemented to elucidate contributing factors to low compliance rates of hand hygiene. Monitoring of compliance was done by trained unknown and known observers and rates of hospital-acquired infections were tracked and correlated against the changes in hand hygiene compliance. In total, 5669 of hand hygiene observations were recorded by the secret observers. The compliance rate increased from 75·4% at baseline (May-August 2014) to 88·6% during the intervention (13 months) and the control periods (P < 0·0001). Reductions in healthcare-associated infection rates were recorded for Clostridium difficle infections from 7·95 (CI 0·8937-28·72) to 1·84 (CI 0·02411-10·26) infections per 10 000 patient-days (P = 0·23), central line-associated blood-stream infections from 5·9 (CI 1·194-17·36) to 2·9 (0·7856-7·475) per 1000 device days (P = 0·37) and catheter-associated urinary tract infections from 5·941 (CI 1·194-17·36) to 0 per 1000 device days (P = 0·42). The top contributing factors for non-compliance were: improper use of gloves, hands full of supplies or medications and frequent entry or exit in isolation areas. We conclude that the application of TST allows healthcare organisations to improve hand hygiene compliance and to identify the factors contributing to non-compliance.

A community outbreak of invasive and non-invasive group A beta-haemolytic streptococcal disease in a town in South Wales.

An increase in the incidence of invasive and non-invasive infections caused by group A beta-haemolytic streptococci (GAS) was noted in and around the town of Glynneath (population approx. 4000) in West Glamorgan, South Wales between 1 January and 30 June 1995. A total of 133 cases was ascertained with 127 (96%) occurring between 1 March and 30 June 1995. Six patients had invasive disease (one died) and all presented at the peak of the outbreak. There were 127 non-invasive cases of whom 7 were hospitalized. The outbreak was investigated to determine its extent and whether it was caused by a single M-serotype of GAS. Serotyping showed that 13 different M-serotypes were involved with the M1 serotype predominating. The overall incidence of GAS invasive disease in West Glamorgan (population 365,000) increased sevenfold from a crude incidence of 0.5/10(5) per year in 1994 to 3.5/10(5) per year in 1995, but fell back to 0.75/10(5) per year in 1996. Eighty-two (80%) out of 102 individuals affected by GAS replied to a health questionnaire; sore throat was the commonest symptom reported (97%). Thirty-nine of these index cases identified at least one other member of their household who had experienced similar symptoms. The interval between the onset of illness in members of a single household was 0-83 days with a mean of 22 days. The mean duration of illness was 13.5 days and 61% of patients were treated with penicillin V for a mean duration of 9.3 days. Twenty-one per cent of GAS isolates were erythromycin-resistant and the M4 and M6 serotypes were especially resistant to erythromycin (87.5 and 100% resistance, respectively). Penicillin V failed to eradicate GAS from the throats of 25% of assessable patients. In this community, an outbreak of non-invasive disease caused by GAS was linked in time and place with an outbreak of serious invasive disease.
