Population-wide sodium reduction: the bumpy road from evidence to policy.

Elevated blood pressure is a highly prevalent condition that is etiologically related to coronary heart disease and stroke, two of the leading causes of morbidity and mortality throughout the world. Excess salt (sodium chloride) intake is a major determinant of elevated blood pressure. In this article, we discuss the scientific rationale for population-wide salt reduction, the types and strength of available evidence, policy-making on dietary salt intake in the United States and other countries, and the role and impact of key stakeholders. We highlight a number of lessons learned, many of which are germane to policy development in other domains.

Accuracy of a radiofrequency identification (RFID) badge system to monitor hand hygiene behavior during routine clinical activities

BACKGROUND Hand hygiene (HH) is a critical part of infection prevention in health care settings. Hospitals around the world continuously struggle to improve health care personnel (HCP) HH compliance. The current gold standard for monitoring compliance is direct observation; however, this method is time-consuming and costly. One emerging area of interest involves automated systems for monitoring HH behavior such as radiofrequency identification (RFID) tracking systems. METHODS To assess the accuracy of a commercially available RFID system in detecting HCP HH behavior, we compared direct observation with data collected by the RFID system in a simulated validation setting and to a real-life clinical setting over 2 hospitals. RESULTS A total of 1,554 HH events was observed. Accuracy for identifying HH events was high in the simulated validation setting (88.5%) but relatively low in the real-life clinical setting (52.4%). This difference was significant (P < .01). Accuracy for detecting HCP movement into and out of patient rooms was also high in the simulated setting but not in the real-life clinical setting (100% on entry and exit in simulated setting vs 54.3% entry and 49.5% exit in real-life clinical setting, P < .01). CONCLUSION In this validation study of an RFID system, almost half of the HH events were missed. More research is necessary to further develop these systems and improve accuracy prior to widespread adoption.

Challenges to School-Located Vaccination: Lessons Learned

School-located vaccination (SLV) has a long history in the United States and has successfully contributed to lower morbidity and mortality due to vaccine-preventable diseases.1 Historically, SLV efforts, which tended to be single-vaccine programs intended to provide catch-up immunization to a defined school-age cohort or were implemented in response to an outbreak, were unfunded, funded by local health department, or were funded by industry or federal grants. The growing palette of vaccines recommended for routine use in adolescents along with limited success of office-based adolescent immunization create a compelling argument for the creation of financially sustainable SLV programs. An arguably significant barrier to both office-based and school-located adolescent immunization is the modest reimbursement rates afforded to immunizers. Because the immunization promotion and consent process is expensive, these costs must be reduced to a minimum to reach financial viability. Although there are challenges to creating a financially sustainable SLV program coordinated by an academic medical center, (AMC), the ability of AMCs to bill private and public insurers, the nonprofit status of medical centers, the allowances for faculty for academic pursuit, and the substantial infrastructure already present make AMCs a potentially practical site for the administration of SLV programs. Alternatively, as health departments throughout the nation continue to explore methods for billing private insurance, we may find health departments to be uniquely suited for coordinating the administration and billing of these services.

Behavioral Intention of Physician Trainees and Medical Students to Practice Hand Hygiene

Physician trainees were surveyed to assess intention to perform hand hygiene (HH). Compared with preclinical medical students (MS), clinical MS and residents reported less confidence that HH prevents carrying home microorganisms (P = .006, P = .003) or protects oneself from antibiotic-resistant microorganisms (P = .01, P = .006). Clinical trainees may need targeted interventions focusing on intention to perform HH.

Assessment of an Aggregate-Level Hand Hygiene Monitoring Technology for Measuring Hand Hygiene Performance among Healthcare Personnel

BACKGROUND Despite significant advances in technological methods for hand hygiene surveillance, a lack of evidence prohibits comparison of systems to one another or against the current gold standard of direct observation. OBJECTIVE To validate a hand hygiene monitoring technology (HHMT) designed to capture hand hygiene behaviors aggregated at the hospital-unit level (GOJO Industries, Akron, OH). METHODS Our team followed a rigorous validation approach to assess the sensitivity and positive predictive value (PPV) of an HHMT. A planned path was first used to measure the accuracy of the system when purposefully activated by investigators. Next, behavioral validation was used to quantify accuracy of the system in capturing real-world behaviors. RESULTS During the planned path phase, investigators performed 4,872 unique events across 3 distinct hospital buildings varying in size and age since construction. Overall sensitivity across the medical center was 88.7% with a PPV of 99.2%. During the behavioral validation phase, trained direct observers recorded 5,539 unique events across 3 distinct hospital buildings. Overall sensitivity across the medical center was 92.7% and PPV was 84.4%. CONCLUSION Objective measures of sensitivity and PPV indicate the promise of the benefit of this and other HHMTs to capture basic behaviors associated with hand hygiene.

Medicaid Managed Care: Unanswered Impact on School-Located Immunization Services

Managed care coordination for Medicaid beneficiaries is being implemented in states across the country. Recently, 1.5 million Medicaid beneficiaries in five regions of Illinois began this transition. This article presents the findings of a study to learn if immunizations would continue to be a reimbursable service if provided to beneficiaries outside of the designated primary care setting. The findings revealed a lack of clarity among health plan representatives and billing personnel in how to obtain coverage information. Five contacted plans (25%) stated they were unable to verify coverage and unclear where to acquire this information. Similarly, six (30%) representatives could not answer the question and recommended calling the Illinois Department of Healthcare and Family Services hot line. Despite the potential benefit of improved coordination of care gained by transitioning to managed care entity model, this infrastructure change may inadvertently introduce barriers to services obtained outside the medical home, like school-located immunization.

Developing An Analytic Approach to Understanding the Patient Care Experience

The amount of data available to health-care institutions regarding the patient care experience has grown tremendously. Purposeful approaches to condensing, interpreting, and disseminating these data are becoming necessary to further understand how clinical and operational constructs relate to patient satisfaction with their care, identify areas for improvement, and accurately measure the impact of initiatives designed to improve the patient experience. We set out to develop an analytic reporting tool deeply rooted in the patient voice that would compile patient experience data obtained throughout the medical center.

Taxi Drivers: A Target Population for the Prevention of Transmissible Disease?

We set out to assess the feasibility and uptake of an on-site influenza vaccination campaign targeting taxi drivers in airport taxicab lots in Chicago, Illinois. Influenza vaccine was provided by the Chicago Department of Public Health as this event aligned with ongoing efforts to provide influenza vaccinations throughout the city. Clinicians and clinic support staff were volunteers recruited from the University of Chicago Medicine and incorporated nursing staff, physicians, physician residents, and administrative support. Together, this allowed for a cost-effective approach to provide free influenza vaccines to the primarily uninsured taxi driver population. During these events, 545 taxi drivers received influenza vaccine in 2012 while 354 drivers were immunized in 2013. Nearly all drivers reported uninsured or under-insured status. The ability to use volunteers and healthcare organization’s desires to meet the needs of the community, in collaboration with often under-staffed but highly dedicated local health departments have the potential to offer valuable public health services to underserved members of the community. Educational initiatives targeting vaccine hesitancy and misinformation may be necessary to improve immunization coverage among this population.
