Outbreaks of HBV-HCV still happening in 2010 March 20, 2010 May 28,2010 May 13, 2010
Injection Safety Measures taken to perform injections in a safe manner for patients and providers Part of Standard Precautions Infection prevention practices that apply to all patients, regardless of suspected or confirmed infection status, in any healthcare setting Healthcare should not provide any opportunity for transmission of bloodborne viruses Patient protections in the context of IV injections should be on par with transfusion safety and healthcare worker safety (OSHA BBP Standard)
Features of HBV, HCV and HIV relevant to healthcare transmission Beltrami et al, Clin Microbio Reviews, 2000. MMWR 2001;50(No. RR-11). Bond et al. Lancet 1981; 8219:550-1. Shikata et al.. J Infect Dis 1977;136:571–76. 7
Era of decreasing acute HBV/HCV incidence • HIV prevention • Hepatitis B vaccine • Screening of blood donors • Healthcare worker safety Decline in healthcare transmission HBV HCV CDC. Surveillance for Acute Viral Hepatitis – United States, 2007. MMWR 2009;58 (No. SS-3).
However, increase in viral hepatitis outbreaks associated with healthcare procedures • Considered uncommon, isolated events in US • Not identified via acute HBV/HCV surveillance data • Increase in the number, size of outbreak investigations, number of persons affected • Increase in attention • Public, media, public health officials, healthcare providers/professional organizations

Standard Precautions • Assume that anyonemight be infected with a bloodborne pathogen • Basic infection control principles that apply every where and every timehealthcare is delivered • Safe Injection Practices • Never administer medications from the same syringe to more than one patient • Do not enter a vial with a used syringe or needle • Minimize the use of shared medications • Maintain aseptic technique at all times
Outbreaks due to Unsafe Injection Practices – Summary of US Experience over the Past Decade • Steady increase in requests for assistance in investigating infections and outbreaks potentially stemming from unsafe injection practices • Over 51 outbreaks of hepatitis B or C have occurred in healthcare settings • Approximately one-fourth investigated in the last 24 mos • Majority attributable to unsafe injection practices or related breakdowns in safe care • Approximately 20 outbreaks involving bacterial pathogens (e.g., drug resistant gram negative and invasive staph infections), typically resulting in bloodstream infections • Prolonged hospitalization and intravenous antibiotics
Healthcare-associated HBV/HCV outbreaks by year reported – US July 1998 to June 2009 • 51 outbreaks (42 non-hospital) • -17 long-term care • -16 outpatient med/surg clinics • -9 hemodialysis • -9 hospital • >75,000 persons potentially exposed • 620 persons newly infected No. of outbreaks
Features of transmission of HBV-HCV OutbreaksJuly 1998 to June 2009 • In non hospital settings (42 of 51, 82%) • Patient-to-patient transmission due to poor infection control practices by staff (47/51, 92%) • During administration of injections • Cross contamination during hemodialysis, blood glucose monitoring • Preventable with standard precautions and aseptic technique
Indirect transmission of HBV during blood glucose monitoring Stable in environment for at least 7 days1 Transmission via contaminated surfaces/equipment High viral titer: virus present in absence of visible blood2 1: Bond et al. Lancet 1981; 8219:550-1. 2: Shikata et al. J Infect Dis 1977;136:571–76. 19
What happens when Safe Injection Practices (SIP) are not followed? • Improper use of syringes, needles, and medication vials has resulted in: • Infection of patients with bloodborne viruses, including hepatitis C virus, and other infections • Notification of thousands of patients of possible exposure to bloodborne pathogens and recommendation for HCV, HBV, and HIV testing • Referral of providers to licensing boards for disciplinary action • Legal actions such as malpractice suits filed by patients
What factors are contributing to an increase in outbreaks in the ambulatory care setting (ACS)?
Trends in Ambulatory Care Visits, United States, 1996-2006 1 http://www.cdc.gov/nchs/data/nhsr/nhsr008.pdf
Growth in Outpatient Care • Shift in healthcare delivery from acute care settings to ambulatory care, long term care and free standing specialty care sites • Dialysis Centers • 2008: 4,950 (72% increase since 1996) • Ambulatory Surgical Centers • 2009: 5175 (240% increase since 1996) • Approximately 1.2 billion outpatient visits / year • Quick turnover of patients • Lack of systematic surveillance to detect infections • Regulatory requirements varied widely settings and little oversight
Viral Hepatitis Outbreaks (n=15) in Outpatient Settings due to Unsafe Injection Practices, 2001-2009 Nearly half of these outbreaks were caused by unsafe injection practices related to anesthesia/sedation MM
FL – pain clinic – 7 cases – Mycobacterium abscessus Epidural injections; all patients required lamenectomy FL – pain clinic – 24 cases – invasive S. aureus Epidural + other lumbar injections; 10 required lamenectomy NYC – pain clinic – 9 cases – Klebsiella pneumoniae Sacroiliac joint injections; 4 patients hospitalized WV – pain clinic – 8 cases – invasive S. aureus Epidural injections; 7 patients hospitalized (range 5-23 days) GA – primary care clinic – 5 cases – S. aureus (MSSA) Joint injections; all patients hospitalized ≥1 week Examples of Bacterial Outbreaks due to Unsafe Injection Practices, 2008-2009 Common elements: reuse of single dose contrast dye and other unsafe injection practices / infection control deficiencies
Patient Notifications for Bloodborne Pathogen Testing Due to Unsafe Injection Practices, Outpatient Settings, 2007–2009 • New York City – Endoscopy clinic – Hepatitis C virus transmission 4,500 patients notified • Long Island, NY – Pain Management Clinic – Hepatitis C virus transmission 10,400 patients notified • Michigan – Dermatologist – Fraud investigation 13,000 patients notified • Las Vegas, NV – Endoscopy clinic – Hepatitis C virus transmission >50,000 patients notified • North Carolina – Cardiology clinic – Hepatitis C virus transmission 1,200 patients notified • New Jersey – Oncology clinic – Hepatitis B virus transmission 6,000 patients notified
What are some of the incorrect practices that have resulted in transmission of pathogens? Direct (i.e., “overt”) syringe reuse Using the same syringe from patient to patient Indirect syringe reuse Accessing shared medication vials or IV bags with a used syringe Reuse of single dose vials Sharing of blood contaminated glucose monitoring equipment
Example of outbreak attributed to Direct Syringe Reuse 2002: Oklahoma pain clinic Example of “multidose syringe” technique Loaded a syringe with enough medication to treat multiple patients Reused this “prefilled’ syringe to inject into heparin lock attached directly to an IV 71 cases of HCV and 31 cases of HBV Comstock et al. ICHE 2004;25:576-583
HCV-infected surgery technician stole fentanyl syringes that had been predrawn and left unattended in ORs Contaminated syringes were refilled with saline and swapped with unused syringes 24 patients infected; nearly 6000 notified Tech sentenced to 30 years Provider-to-Patient Transmission of Hepatitis C Virus Associated with Diversion of Fentanyl, Colorado 2009
Narcotics Theft a.k.a. “Diversion” • Diversion has emerged as the leading cause of provider to patient HCV transmission • Prevention needs extend beyond traditional “infection control” • Limit opportunities for access or deception • Good example of need for safety- engineered solutions and system approach
Indirect Syringe ReuseNevada endoscopy center HCV outbreak investigation, 2008 • Syringes were reused to withdraw multiple doses for individual patients • Remaining volume in single dose propofol vials was used for subsequent patients • The vial became the vehicle for HCV spread
Example of outbreak attributed to reuse of single dose vials
1991-1993, 7 hospitals experienced outbreaks traced to mishandling of propofol Six different bacterial pathogens Wide variety of lapses in aseptic technique “...the larger vials look like multidose vials, and our investigations revealed that the vials are sometimes being used for an extended period of time, for more than one patient or procedure, and to refill syringes meant to be used only once.” NEJM 1995 333:147-154
Pain Clinic – 7 cases – Serratia marcescens Spinal injections; all patients hospitalized Breaches in aseptic handling of injections Reuse of syringes to access/combine multiple medications likely resulted in extrinsic contamination of reused single-dose vials of contrast solution Clin J Pain 2008;24:374–380

ARCH INTERN MED/VOL 170 (NO. 8), APR 26, 2010 • Overall, 74% of drug administrations had at least 1 procedural failure; 25% had clinical errors • Interruptions occurred in 53% of administrations • Error rate and severity increased with the number of interruptions • Aseptic technique compliance was 83%
Examples of outbreaks attributed to sharing blood contaminated glucose monitoring equipment
Practices associated with HBV transmission during assisted blood glucose monitoring: re-use of blood contaminated devices, poor infection control Sharing of fingerstick devices Blood contamination of glucose testing meters Failure to change or use gloves, perform hand hygiene between procedures Patel et al. ICHE 2009;30:209-14 Thompson et al. JAGS 2010; 58:914–918, 2010. 40
An emerging problem: the new generation of devices Sharing of multi-lancet fingerstick devices reported as cause of HBV infection outbreak in Nursing Home1 Multi-lancet fingerstick device Sharing of multidose insulin pens reported2,3 Multidose Insulin Pens 41 1: Gotz et al. Eurosurveillance 2008;13:1-4 2: www.newsinferno.com/archives/3066 3. www.lcsun-news.com/ci_11670031
A comprehensive approach is needed Surveillance and investigation capacity Recognize and contain transmission Inform prevention Professional oversight, licensing, and public awareness Healthcare provider education and training Improvements in medical devices and medication packaging Patient empowerment
Oversight and Enforcement Increasing efforts to strengthen regulatory and accreditation standards across healthcare settings Particular focus on infection control Collaboration with the Centers for Medicare and Medicaid Services Expanded incorporation of infection control requirements into conditions for coverage and inspection procedures
Infection control survey tool for ambulatory surgical centers http://www.cms.hhs.gov/SurveyCertificationGenInfo/downloads/SCLetter09_37.pdf
Labeling and sizing that are appropriate for the clinical setting and application • Injection versus infusion / IV drip
Cost containment and the drive for efficiency Trend toward patient care settings where infection control programs are lacking Ingrained behaviors – “unthinking force of habit” “Culture of complacency” vs. “safety culture” Challenges
Unsafe injection practices are not intentional but result from lack of knowledge, misperceptions, and mistaken beliefs
Misperceptions • I changed the needle so I can reuse the syringe • The vial says single does but it has enough medication for more than one patient, so I can use it
How have providers justified syringe reuse? Mistaken belief that the following practices prevent contamination and infection transmission Changing ONLY the needle between patients (not the syringe) Injecting through intervening lengths of IV tubing Maintaining constant pressure on the plunger to prevent backflow Lack of visible contamination or blood
