Using High-Technology to Enforce Low-Technology Safety Measures: The Use of Third-party Remote Video Auditing and Real-time Feedback in Healthcare

BACKGROUND Hand hygiene is a key measure in preventing infections. We evaluated healthcare worker (HCW) hand hygiene with the use of remote video auditing with and without feedback. METHODS The study was conducted in an 17-bed intensive care unit from June 2008 through June 2010. We placed cameras with views of every sink and hand sanitizer dispenser to record hand hygiene of HCWs. Sensors in doorways identified when an individual(s) entered/exited. When video auditors observed a HCW performing hand hygiene upon entering/exiting, they assigned a pass; if not, a fail was assigned. Hand hygiene was measured during a 16-week period of remote video auditing without feedback and a 91-week period with feedback of data. Performance feedback was continuously displayed on electronic boards mounted within the hallways, and summary reports were delivered to supervisors by electronic mail. RESULTS During the 16-week prefeedback period, hand hygiene rates were less than 10% (3933/60 542) and in the 16-week postfeedback period it was 81.6% (59 627/73 080). The increase was maintained through 75 weeks at 87.9% (262 826/298 860). CONCLUSIONS The data suggest that remote video auditing combined with feedback produced a significant and sustained improvement in hand hygiene.

Methicillin-susceptible Staphylococcus aureus ST398, New York and New Jersey, USA.

To the Editor: Clinical infections with livestock-associated Staphylococcus aureus sequence type (ST) 398 have been reported in Europe, Canada, and the People’s Republic of China (1), as well as the Caribbean (2,3), and Colombia (4). Most reports describe infection with methicillin-resistant S. aureus; relatively few describe infection with methicillin-susceptible S. aureus (MSSA). In the United States, colonization of healthy adults by ST398 has been reported in Iowa (5) and in New York, New York (2); MSSA infections have been anecdotally reported in St. Louis, Missouri (6), and The Bronx, New York (7). We describe 8 infections with MSSA ST398 in the New York City area during a 7-year period (2004–2010). Five infections with a related ST (ST291) from clonal complex (CC) 398 also were identified. These findings highlight the emergence of clinical infections with 2 distinct CC398 sequence types in the New York City area. Retrospective typing of 4,167 clinical S. aureus isolates from various studies involving inpatients and outpatients in the New York City area identified 13 mecA-negative isolates with CC398-associated spa types (Table). Nine isolates were obtained from cultures of outpatients with skin and soft tissue infections; samples were submitted by physicians in the community. One isolate was associated with recurring skin and soft tissue infections in multiple body sites (BK21466); another was associated with genital infection (BK21732). Of the 4 ST398 isolates derived from bloodstream infections in hospitalized patients, 3 were recovered from intravenous drug users, 1 of whom died 1 day after admission for variceal bleeding (BK26722). Unlike the multidrug-resistant ST398 MSSA recently described in Colombia (4), most isolates in this study were susceptible to all antimicrobial drugs tested except penicillin, although several strains exhibited resistance to clindamycin and erythromycin. One isolate (BK23527) was submitted as oxacillin resistant (MIC ≥4 μg/mL) but lacked the mecA gene, which suggested that another mechanism was contributing to the resistance phenotype. Table Characteristics of Staphylococcus aureus clonal complex 398 isolates, New York and New Jersey, USA, 2004–2010* Multilocus sequence typing confirmed 8 isolates as ST398 (3–35–19–2–20–26–39); 5 isolates were assigned to ST291 (3–37–19–2–20–26–32), a double-locus variant of ST398 (Figure A1, panel A). Most of the ST398 strains were spa type 109 (t571), described in MSSA carriage isolates from New York City (2) and MSSA infections from China (1), France (8), Martinique (3), the Dominican Republic (2,3), and Colombia (4). BURP (based upon repeat pattern) analysis clustered all of the spa types into spa-CC t571 (Figure A1, panel B); ST398 isolates clustered with spa type 109 (t571), whereas ST291 isolates clustered with spa type 865 (t2313). Pulsed-field gel electrophoresis was also performed on the 11 available isolates. Although the ST291 isolates were sensitive to digestion with SmaI, pulsed-field gel electrophoresis was performed with Cfr9I to compare all isolates simultaneously. As expected, the ST398 and ST291 isolates clustered separately (data not shown); 4 distinct patterns were observed within each cluster (Table). Only the ST398 isolates were positive for a CC398 lineage-specific PCR that targets the unique restriction-modification system sau1-hsdS1 (9), further highlighting the differences between ST291 and ST398. None of the isolates harbored the genes coding for Panton-Valentine leukocidin. Because of the retrospective nature of the findings, epidemiologic information for each isolate was limited. One patient (BK19382) reported travel to the Dominican Republic; Caribbean nationality was reported for BK27037 (Puerto Rico) and BK31274 (Trinidad). The cases described here occurred in urban and suburban settings, reflecting the likelihood that exposure to livestock was relatively low; however, travel history was unknown for most of the patients. Previous reports have linked ST398 transmission to other reservoirs, including companion animals, live animal food markets, and commercial meat products (1,2). However, data from a recent genome sequencing study suggest that MSSA ST398 is human in origin (10); other evidence suggests that certain lineages, particularly spa type 109 (t571), might circulate at low levels in humans in the absence of livestock exposure (8). Our findings seem to support the hypothesis of low-level ST398 MSSA prevalence, and further surveillance might uncover additional cases of colonization or infection with ST398- and ST291-related strains in the New York City area. For example, active surveillance cultures performed at one of the 3 hospitals during January–March 2009 detected 7 additional ST398 and 3 additional ST291 isolates among 260 MSSA carriage strains (data not shown). In addition to the intrinsic virulence exhibited by ST398 MSSA in previous studies, the potential to acquire resistance to multiple classes of antimicrobial drugs (1,4,10), as well as virulence factors such as Panton-Valentine leukocidin (8), warrants continued surveillance in light of recent ST398 methicillin-resistant S. aureus outbreaks in health care settings (1).

Clinical Significance of Neutropenia in Patients With Human Immunodeficiency Virus Infection

OBJECTIVE To determine the incidence of infection in human immunodeficiency virus (HIV)-infected patients during periods of neutropenia and non-neutropenia. To compare the infection rates in patients with HIV disease to those in a group hospitalized with neutropenia and hematologic malignancy. DESIGN Prospective observational study conducted between December 1985 and December 1987 at a university teaching hospital. Thirty patients with documented acquired immunodeficiency syndrome (AIDS) and absolute T-helper cells less than 200 mm/mm3. All patients had a period of non-neutropenia following a neutropenic period (neutrophils less than 1000 cells/mm3). RESULTS The rate of first infection during neutropenic and non-neutropenic periods for opportunistic infection and nonopportunistic infections were compared. There were no differences between infection rates for the two time periods for both types of infections. A subgroup of patient care days in which non-neutropenic days followed neutropenic days also was studied to eliminate selection bias. In this group, a comparison of infection rates also revealed no difference between neutropenic and non-neutropenic periods. An alternate analysis of the time until first infection during periods of neutropenia or non-neutropenia was done using the Kaplan-Meier product limit method. There was a longer infection-free period for the neutropenic group for opportunistic infections, but it was not statistically significant (p less than .1). In addition, we compared HIV-infected patients with a group of 37 patients with neutropenia from hematologic malignancy. There was a significantly higher rate of all infections, particularly bacteremias (p less than .001), in the group of patients with hematologic malignancies when compared with all subsets of patients with HIV disease. CONCLUSION We conclude that patients with HIV disease and modest neutropenia do not have an increased risk of bacterial infection. The incidence of all infections is significantly greater in patients with neutropenia secondary to hematologic malignancy.

Replicating changes in hand hygiene in a surgical intensive care unit with remote video auditing and feedback

Using remote video auditing (RVA) and real-time feedback, we replicated health care workers hand hygiene in a second intensive care unit. During the first 4 weeks using RVA without feedback, the compliance rate was 30.42%. The rate during the 64-week postfeedback period (initial 16 and 48 weeks maintenance) with RVA and feedback exceeded 80% on average. These data demonstrate that improved hand hygiene was achieved and sustained with the use of RVA and feedback.

Remote video auditing with real-time feedback in an academic surgical suite improves safety and efficiency metrics: a cluster randomised study

Importance Compliance with the surgical safety checklist during operative procedures has been shown to reduce inhospital mortality and complications but proper execution by the surgical team remains elusive. Objective We evaluated the impact of remote video auditing with real-time provider feedback on checklist compliance during sign-in, time-out and sign-out and case turnover times. Design, setting Prospective, cluster randomised study in a 23-operating room (OR) suite. Participants Surgeons, anaesthesia providers, nurses and support staff. Exposure ORs were randomised to receive, or not receive, real-time feedback on safety checklist compliance and efficiency metrics via display boards and text messages, followed by a period during which all ORs received feedback. Main outcome(s) and measure(s) Checklist compliance (Pass/Fail) during sign-in, time-out and sign-out demonstrated by (1) use of checklist, (2) team attentiveness, (3) required duration, (4) proper sequence and duration of case turnover times. Results Sign-in, time-out and sign-out PASS rates increased from 25%, 16% and 32% during baseline phase (n=1886) to 64%, 84% and 68% for feedback ORs versus 40%, 77% and 51% for no-feedback ORs (p<0.004) during the intervention phase (n=2693). Pass rates were 91%, 95% and 84% during the all-feedback phase (n=2001). For scheduled cases (n=1406, 71%), feedback reduced mean turnover times by 14% (41.4 min vs 48.1 min, p<0.004), and the improvement was sustained during the all-feedback period. Feedback had no effect on turnover time for unscheduled cases (n=587, 29%). Conclusions and relevance Our data indicate that remote video auditing with feedback improves surgical safety checklist compliance for all cases, and turnover time for scheduled cases, but not for unscheduled cases.

Factors influencing nurse compliance with Standard Precautions

BACKGROUND Exposure to blood and bodily fluids represents a significant occupational risk for nurses. The most effective means of preventing bloodborne pathogen transmission is through adherence to Standard Precautions (SP). Despite published guidelines on infection control and negative health consequences of noncompliance, significant issues remain around compliance with SP to protect nurses from bloodborne infectious diseases, including hepatitis B virus, hepatitis C virus (HCV), and HIV. METHODS A descriptive correlational study was conducted that measured self-reported compliance with SP, knowledge of HCV, and perceived susceptibility and severity of HCV plus perceived benefits and barriers to SP use. Relationships between the variables were examined. Registered nurses (N = 231) working in ambulatory settings were surveyed. RESULTS Fewer than one-fifth (17.4%) of respondents reported compliance with all 9 SP items. Mean score for correct responses to the HCV knowledge test was 81%. There was a significant relationship between susceptibility of HCV and compliance and between barriers to SP use and compliance. CONCLUSIONS This study explored reasons why nurses fail to adopt behaviors that protect them and used the Health Belief Model for the theoretical framework. It concentrated on SP and HCV because more than 5 million people in the United States and 200 million worldwide are infected with HCV, making it 1 of the greatest public health threats faced in this century. Understanding reasons for noncompliance will help determine a strategy for improving behavior and programs that target the aspects that were less than satisfactory to improve overall compliance. It is critical to examine factors that influence compliance to encourage those that will lead to total compliance and eliminate those that prevent it.

Improving awareness of best practices to reduce surgical site infection: a multistakeholder approach.

Surgical site infection (SSI) is recognized as a focus area by the Centers for Medicare and Medicaid Services, the Joint Commission, the Institute for Healthcare Improvement, and the Institute of Medicine. An estimated 47% to 84% of SSIs present after discharge from the hospital or ambulatory care facility and, as a result, go undetected by standard SSI surveillance programs. Evidence-based processes and practices that are known to reduce the incidence of SSIs tend to be underused in routine practice. This article describes a multistakeholder process used to develop an educational initiative to raise awareness of best practices to reduce SSIs. The goal was to create a patient-centric educational initiative that involved an active partnership among all stakeholders—medical professional organizations, hospitals/health systems, health insurers, employers and other purchasers, and consumers/patients—to provide the climate necessary to create and sustain a culture of safety.

Modifying the risk: Once-a-day bathing "at risk" patients in the intensive care unit with chlorhexidine gluconate

Chlorhexidine gluconate (CHG) decreases hospital-acquired methicillin-resistant Staphylococcus aureus (MRSA) that can cause colonization and infection. A standard approach is the bathing of all patients with CHG to prevent MRSA transmission. To decrease CHG utilization, this study assessed selective daily administration of CHG bathing to intensive care unit patients who had an MRSA-positive result or a central venous catheter. This risk-based approach was associated with a 72% decrease in hospital-acquired MRSA transmission rate.
