Analysis of Intervention Employability in Pharmacy-Related Medication Safety Reports at a Tertiary Medical Center.

Background: The Institute for Safe Medication Practice (ISMP) suggests that patient safety reports be addressed with systematic, fail-safe, actions to prevent error recurrence. ISMP's hierarchy of effectiveness of risk reduction strategies places education-related interventions as the least effective and fail-safes at the top. UNM Hospitals creates a positive environment for safety reporting, but often we are limited to education interventions due to resource and technology constraints. This study analyzes the intervention potential and quality of pharmacy-related medication safety reports. Methods: One thousand medication-related safety reports from selected time points between 2012 and 2022 were selected. Safety reports were included in our study if they were actionable by the pharmacy department. Each safety report was categorized by type of safety event and given an intervention potential score of 1 to 10 (1 indicating education-only, 10 being forcing function) by 2 student pharmacists and 1 pharmacy director based on their potential place on ISMP's hierarchy. Safety report quality was graded based on professionalism, organization, clarity, and completeness. A standardized evaluation form was used for evaluation for all elements. Results: Six-hundred-sixty-five safety reports were pharmacy-related and evaluated by all 3 study team members for analysis. The 3 most common pharmacy-related safety reports were medication delivery, inappropriate order verification, and transcribing errors which accounted for over half of the reports (59.5%) and on average the intervention potential score of these types of safety reports was education only. Overall, safety reports were limited to a maximum actionability of education-only 75.4% of the time. Safety reports were found to be professionally written and well organized. Conclusion: The actionability of most pharmacy-related medication safety reports was limited to low leverage interventions likely because high leverage solutions were addressed with systematic change and did not recur. Errors limited to education interventions repeated and this increased relative counts of low leverage actionability of safety reports. The ISMP hierarchy of effectiveness of risk-reduction strategies is an important guide to intervening in medication-related safety events, but pharmacy staff should not be discouraged if most of the safety reports cannot be addressed through high-leverage interventions.

Cross-sectional study of the association of social relationship resources with Staphylococcus aureus colonization in naturally occurring social groups along the US/Mexico border.

Asymptomatic carriage of Staphylococcus aureus is a major risk factor for subsequent clinical infection. Diminishing returns from mitigation efforts emphasize the need to better understand colonization, spread, and transmission of this opportunistic pathogen. While contact with other people presents opportunities for pathogen exposure and transmission, diversity of social connections may be protective against pathogens such as the common cold. This study examined whether social relationship resources, including the amount and diversity of social contacts, are associated with S. aureus colonization. Participants were community members (N = 443; 68% Hispanic) in naturally occurring social groups in southwestern Arizona. Four types of social relationships and loneliness were assessed, and samples from the skin, nose and throat were obtained to ascertain S. aureus colonization. Overall S. aureus prevalence was 64.8%. Neither the amount nor the diversity of social contacts were associated with S. aureus colonization. The concurrent validity of the social relationship assessments was supported by their moderate intercorrelations and by their positive association with self-rated health. The results suggest that the association of social network diversity and susceptibility to the common cold does not extend to S. aureus colonization. Conversely, colonization prevalence was not higher among those with more social contacts. The latter pattern suggests that social transmission may be relatively infrequent or that more intimate forms of social interaction may drive transmission and colonization resulting in high community prevalence of S. aureus colonization. These data inform communicable disease control efforts.

A Quantitative Assessment of Staphylococcus aureus Community Carriage in Yuma, Arizona.

BACKGROUND: Disease control relies on pathogen identification and understanding reservoirs. Staphylococcus aureus infection prevention is based upon decades of research on colonization and infection, but diminishing returns from mitigation efforts suggest significant knowledge gaps. Existing knowledge and mitigation protocols are founded upon culture-based detection, with almost no information about pathogen quantities. METHODS: We used culture and a quantitative polymerase chain reaction assay on samples from 3 body sites to characterize colonization more comprehensively than previous studies by describing both prevalence and pathogen quantity. RESULTS: We show a much higher overall prevalence (65.9%) than previously documented, with higher quantities and prevalence associated with the nares, non-Hispanic males (86.9%), and correlating with colonization in other body sites. These results suggest that research and clinical practices likely misclassify over half of colonized persons, limiting mitigation measures and their impact. CONCLUSIONS: This work begins the process of rebuilding foundational knowledge of S aureus carriage with more accurate and wholistic approaches.

SaQuant: a real-time PCR assay for quantitative assessment of Staphylococcus aureus.

BACKGROUND: Molecular assays are important tools for pathogen detection but need to be periodically re-evaluated with the discovery of additional genetic diversity that may cause assays to exclude target taxa or include non-target taxa. A single well-developed assay can find broad application across research, clinical, and industrial settings. Pathogen prevalence within a population is estimated using such assays and accurate results are critical for formulating effective public health policies and guiding future research. A variety of assays for the detection of Staphylococcus aureus are currently available. The utility of commercial assays for research is limited, given proprietary signatures and lack of transparent validation. RESULTS: In silico testing of existing peer-reviewed assays show that most suffer from a lack of sensitivity and specificity. We found no assays that were specifically designed and validated for quantitative use. Here we present a qPCR assay, SaQuant, for the detection and quantification of S. aureus as might be collected on sampling swabs. Sensitivity and specificity of the assay was 95.6 and 99.9 %, respectively, with a limit of detection of between 3 and 5 genome equivalents and a limit of quantification of 8.27 genome equivalents. The presence of DNA from non-target species likely to be found in a swab sample, did not impact qualitative or quantitative abilities of the assay. CONCLUSIONS: This assay has the potential to serve as a valuable tool for the accurate detection and quantification of S. aureus collected from human body sites in order to better understand the dynamics of prevalence and transmission in community settings.
