Method(s):
Antimicrobial use and incidence of MDRO in bloodstream
infections are mandatorily reported by intensive care units to Sao
Paulo State Health Department. Antibiotics were grouped by class and
expressed in defined daily doses (DDD) per 1000 patient-days(pd),
from 2009 to 2013. MDRO were grouped into resistant to 3rd
generation cephalosporins, carbapenems and oxacillin and compared
to carbapenems, polymyxins and glycopeptides use. Hospitals were
grouped in private, philanthropic and public. Public hospitals were
divided into social organization (SO) or not, the former is privately
managed with public funding. Correlation between MDRO incidence
and antibiotic use was investigated for 2012 and 2013.
Results:
Between 2009 and 2013, mean number of reporting hospitals
was 198. 35% of reporting hospitals were public and 33% of these
were SO. Cephalosporins were the most prescribed drugs, although
there was a decreasing trend in the period. Polymyxins had the
greatest increase in use (125%), mostly in public hospitals. Among
public hospitals, comparing SO and public administration there was a
difference in antimicrobial use for glycopeptides, carbapenems and
polymyxins (p = 0.04, 0.008 and 0.001). There was no difference in
MDRO incidence.
Discussion and/or Conclusion(s):
In conclusion, we observed a
significant increase in polymyxin use. In the public level, we observed
a discrepancy between the incidence of MDRO and broad-spectrum
antibiotics use in different administrative regimens. These data should
guide public health policies.

Long-term validity of preventive measures against needlestick
injuries in the operating theatre
Shigeru Koyama, Yuko Momoi.
Tokyo Metropolitan Hiroo Hospital
Background:
Due to the high reporting rate of needlestick injuries in
the operating theatre, we implemented new preventive measures in
2006. These preventivemeasures were previously found to be effective
in a 4-year research project (J Hosp Infect. 2010 Oct (76): S64).
Aim(s)/Objective(s):
To estimate the long-term validity of our pre-
ventive measures against needlestick injury in the operating theatre.
Method(s):
We examined reports of needlestick injury between 2001
and 2015, and compared the 5 years before the implementation of the
preventive measures (Period I: 2001
∼
2005) with the subsequent 10
years (Period II: 2006
∼
2015) to evaluate the validity of these measures
in the operating theatre.
Results:
A total of 439 reports were made between 2001 and 2015,
including 114 reports from the operating theatre. The reporting rate
fell significantly from 32% (52/164) in Period I to 23% (62/275;
p = 0.0036) in Period II. Analysing the contents, rates at intraoperative
management and delivery of instruments were significantly reduced
from 17% to 12% (p = 0.015) and from 7% to 3% (p = 0.015), respectively.
Conversely, the rate at equipment disposal showed no change (4%). The
rate of hepatitis C virus-positive injuries showed no significant change
(Period I, 15%; Period II, 16%), suggesting that the submission rate of
reports was largely static. Results after implementation were also
similar, comparing the first 5 years with the subsequent 5 years.
Discussion and/or Conclusion(s):
Our preventive measures against
needlestick injuries in the operating theatrewere confirmed as valid in
this long-term research. Further measures are needed to prevent
injuries during equipment disposal.

Background:
Observational hand hygiene auditing (OHHA) involves a
trained observer monitoring healthcare worker compliance with five
identified moments for hand hygiene. The effectiveness of OHHA is
uncertain despite widespread adoption.
Aim(s)/Objective(s):
To examine the effect of OHHA on the incidence
of methicillin resistant
Staphylococcus aureus
(MRSA) and vancomycin
resistant enterococci (VRE) bacteraemia.
Method(s):
We conducted a retrospective time series in four acute
hospitals in the Republic of Ireland over the period 2009 to 2014. The
OHHA intervention was introduced to three sites in 2011; the fourth
site acted as a control and did not introduce OHHA. We compared the
change in the incidence of methicillin resistant
Staphylococcus aureus
(MRSA) bacteraemia, vancomycin resistant enterococci (VRE) bacter-
aemia and alcohol based hand gel (ABHR) consumption, in interven-
tion versus control sites.
Results:
There was a significant reduction in MRSA bacteraemia in the
control (p < 0.01) but not the intervention (p = 0.77) sites over the
study period. When the difference of the differences was compared
there was no statistically significant difference (p = 0.09) between
intervention and control sites. There was no significant reduction in
VRE bacteraemia in the control (p = 0.18) or intervention (p = 0.42)
sites. There was a significant increase in ABHR consumption in the
intervention (p = <0.01) sites and a decrease in ABHR consumption in
the control (p = 0.05) site. When the difference of the differences was
compared this was not statistically significant (p = <0.07) in either the
intervention or control sites.
Discussion and/or Conclusion(s):
The implementation of OHHA does
not appear to be associated with a reduction in bacteraemia or with an
increase in ABHR consumption.

Enhanced
Staphylococcus aureus
Bacteraemia
Surveillance (eSABS) to standardise the reporting of SAB infections
were introduced nationally in 2014. The Infection Prevention and
Control Team (IPCT) formed a group to facilitate the appropriate data
collection. Focusing on risk and contributory factors the group aimed
to determine if SABs were avoidable or not. All cases were reviewed to
ensure they were managed in line with guidance on management of
proven or suspected
SAB
in adults
Aim(s)/Objective(s):
This initiative aimed to better understand
the cause of the SAB, determine the potential avoidance, to intervene
to minimize the risk of a SAB occurring due to the same cause
again.
Method(s):
Using the Plan Do Study Act cycle and the national eSAB
tool, a surveillance form was created for the IPCT to investigate the
SAB. Identifying the entry point, source and record procedures/
interventions in the last 30 days. Assessments were made regarding
medical history, device placement, and whether the patient had
any prosthetics. For quality improvement the group reviewed the
implementation and completion of bundles such as Peripheral, Central
Vascular and Urinary Catheter.
Discussion and/or Conclusion(s):
The IPCT along with the multidis-
ciplinary team discuss the results of the surveillance and identify
quality improvement. Audits ar carried out if the SAB is found to be
related to a device. IPCT engage with clinical teams to assist with the
implementation of bundles and support auditing. Clinicians in
charge received a letter detailing the outcome of SAB surveillance,
offering the chance to respond to the information. The Microbiologists
offer to attend educational meetings for further discussions.
