Infection Prevention and Control in the Podiatric Medical Setting. Challenges to Providing Consistently Safe Care.

Unsafe practices are an underestimated contributor to the disease burden of bloodborne viruses. Outbreaks associated with failures in basic infection prevention have been identified in nonhospital settings with increased frequency in the United States during the past 15 years, representing an alarming trend and indicating that the challenge of providing consistently safe care is not always met. As has been the case with most medical specialties, public health investigations by state and local health departments, and the Centers for Disease Control and Prevention, have identified some instances of unsafe practices that have placed podiatric medical patients at risk for viral, bacterial, and fungal infections. All health-care providers, including podiatric physicians, must make infection prevention a priority in any setting in which care is delivered.

Outbreak of hepatitis B virus infections associated with assisted monitoring of blood glucose in an assisted living facility-Virginia, 2010.

INTRODUCTION: In January 2010, the Virginia Department of Health received reports of 2 hepatitis B virus (HBV) infections (1 acute, 1 chronic) among residents of a single assisted living facility (ALF). Both infected residents had diabetes and received assisted monitoring of blood glucose (AMBG) at the facility. An investigation was initiated in response. OBJECTIVE: To determine the extent and mechanism of HBV transmission among ALF residents. DESIGN: Retrospective cohort study. SETTING: An ALF that primarily housed residents with neuropsychiatric disorders in 2 adjacent buildings in Virginia. PARTICIPANTS: Residents of the facility as of March 2010. MEASUREMENTS: HBV serologic testing, relevant medical history, and HBV genome sequences. Risk ratios (RR) and 95% confidence intervals (CIs) were used to identify risk factors for HBV infection. RESULTS: HBV serologic status was determined for 126 (91%) of 139 residents. Among 88 susceptible residents, 14 became acutely infected (attack rate, 16%), and 74 remained uninfected. Acute HBV infection developed among 12 (92%) of 13 residents who received AMBG, compared with 2 (3%) of 75 residents who did not (RR  = 35; 95% CI, 8.7, 137). Identified infection control breaches during AMBG included shared use of fingerstick devices for multiple residents. HBV genome sequencing demonstrated 2 building-specific phylogenetic infection clusters, each having 99.8-100% sequence identity. LIMITATIONS: Transfer of residents out of the facility prior to our investigation might have contributed to an underestimate of cases. Resident interviews provided insufficient information to fully assess behavioral risk factors for HBV infection. CONCLUSIONS: Failure to adhere to safe practices during AMBG resulted in a large HBV outbreak. Protection of a growing and vulnerable ALF population requires improved training of staff and routine facility licensing inspections that scrutinize infection control practices.

Infection control practices in assisted living facilities: a response to hepatitis B virus infection outbreaks.

BACKGROUND: The medical needs of the approximately 1 million persons residing in assisted living facilities (ALFs) continually become more demanding. Moreover, the number of ALF residents is expected to double by 2030. ALFs are not subject to federal oversight; state regulations that govern ALF infection control are variable. In 2005, two outbreaks of acute hepatitis B virus (HBV) infection in ALFs in Virginia were associated with sharing fingerstick devices used in blood glucose monitoring. OBJECTIVE: To characterize infection control practices, determine compliance with guidelines, and identify educational and policy needs in ALFs in Virginia. METHODS: Following the outbreaks of HBV infection, educational packets were sent to ALFs in Virginia to inform them of infection control guidelines and recommendations regarding glucose monitoring. A follow-up survey consisting of on-site interviews was conducted in a random sample of ALFs. Differences among infection control practices, according to the size and ownership of the ALFs, were assessed. RESULTS: Fifty of 155 ALFs in central Virginia were surveyed. Of the 45 ALFs that had used fingerstick devices, 7 (16%) had shared these devices (without cleaning) between residents. Sharing practices for glucose monitoring equipment did not differ by facility size or ownership. Of all 50 ALFs, 17 (34%) did not offer employees HBV vaccine. HBV vaccine was less frequently offered at ALFs that had fewer than 50 residents, compared with ALFs with at least 50 residents (P<.01), and HBV vaccine was less frequently offered at ALFs that were individually owned, compared with those that were not individually owned (P=.02). CONCLUSIONS: Despite outreach and long-standing recommendations, approximately 1 in 6 facilities shared fingerstick devices, and more than one-third of ALFs surveyed were considered noncompliant with federal guidelines (Occupational Safety and Health Administration Bloodborne Pathogens Standard). Public health and licensing agencies should work with ALFs to implement infection control measures and prevent disease transmission.
