Urine biomarkers individually and as a consensus model show high sensitivity and specificity for detecting UTIs.

BACKGROUND: Current diagnoses of urinary tract infection (UTI) by standard urine culture (SUC) has significant limitations in sensitivity, especially for fastidious organisms, and the ability to identify organisms in polymicrobial infections. The significant rate of both SUC "negative" or "mixed flora/contamination" results in UTI cases and the high prevalence of asymptomatic bacteriuria indicate the need for an accurate diagnostic test to help identify true UTI cases. This study aimed to determine if infection-associated urinary biomarkers can differentiate definitive UTI cases from non-UTI controls. METHODS: Midstream clean-catch voided urine samples were collected from asymptomatic volunteers and symptomatic subjects ≥ 60 years old diagnosed with a UTI in a urology specialty setting. Microbial identification and density were assessed using a multiplex PCR/pooled antibiotic susceptibility test (M-PCR/P-AST) and SUC. Three biomarkers [neutrophil gelatinase-associated lipocalin (NGAL), and Interleukins 8 and 1ß (IL-8, and IL-1ß)] were also measured via enzyme-linked immunosorbent assay (ELISA). Definitive UTI cases were defined as symptomatic subjects with a UTI diagnosis and positive microorganism detection by SUC and M-PCR, while definitive non-UTI cases were defined as asymptomatic volunteers. RESULTS: We observed a strong positive correlation (R2 > 0.90; p < 0.0001) between microbial density and the biomarkers NGAL, IL-8, and IL-1ß for symptomatic subjects. Biomarker consensus criteria of two or more positive biomarkers had sensitivity 84.0%, specificity 91.2%, positive predictive value 93.7%, negative predictive value 78.8%, accuracy 86.9%, positive likelihood ratio of 9.58, and negative likelihood ratio of 0.17 in differentiating definitive UTI from non-UTI cases, regardless of non-zero microbial density. NGAL, IL-8, and IL-1ß showed a significant elevation in symptomatic cases with positive microbe identification compared to asymptomatic cases with or without microbe identification. Biomarker consensus exhibited high accuracy in distinguishing UTI from non-UTI cases. CONCLUSION: We demonstrated that positive infection-associated urinary biomarkers NGAL, IL-8, and IL-1ß, in symptomatic subjects with positive SUC and/or M-PCR results was associated with definitive UTI cases. A consensus criterion with ≥ 2 of the biomarkers meeting the positivity thresholds showed a good balance of sensitivity (84.0%), specificity (91.2%), and accuracy (86.9%). Therefore, this biomarker consensus is an excellent supportive diagnostic tool for resolving the presence of active UTI, particularly if SUC and M-PCR results disagree.

Identification of Workload Measurement Indicators for School Nursing Practice.

Many school districts rely on caseload or student to school nurse ratios that are not grounded in evidence-based research. There is a need for a comprehensive workload instrument to describe the work of school nurses that incorporates the complexities of the role and includes acuity, care processes, and social determinants of health. The purpose of this qualitative study was to identify workload activities from a previous Delphi study that can be empirically measured as items for a workload instrument. A nationally representative sample of 27 school nurses participated in four focus groups, describing activities important to the measurement of workload. Focus group input resulted in identification and confirmation of workload activities that impact school nurse workload. Use of the National Association of School Nurses' Framework for 21st Century School Nursing Practice™ was integral in capturing gaps and important workload activities for a potential workload instrument.

U.S. School Nursing Job Analysis.

The complexity and demands of the school nurse role have changed greatly over time. Our aims included determining tasks and knowledge relevant to modern school nursing in the United States, identifying continuing education needs of school nurses, and describing anticipated changes to the professional role. A secondary analysis of a cross-sectional web-based survey of 750 school nurses was performed. The study team evaluated calculations of mean importance and frequency for school nursing task and knowledge statements. Conventional content analysis was used to analyze open-ended responses. School nurses rated most tasks and knowledge as relevant to practice, underscoring the great depth and breadth of education and training school nurses need to meet the demands of students today. The results of this secondary analysis may be leveraged to accurately describe the school nurse role, advocate for nursing services, and support school nurses as they strive to better the health of school communities.

Impact of mentoring relationships on nursing professional socialization.

AIM: This study qualitatively explored the impact mentoring relationships had on the professional socialization of novice clinical nurse leader. BACKGROUND: Professional socialization entails acquisition of the skills, knowledge and values associated with nursing. Model C clinical nurse leaders have completed a bachelor's degree before graduate-level nursing programme acceptance. Thereby, the mentoring needs of model C clinical nurse leaders may differ from that of traditionally educated novice nurses. METHOD: Focus groups were conducted with seven novice model C clinical nurse leaders during their first year of employment. Qualitative data were analysed via a grounded theory approach. RESULTS: The participants described an intense focus on patient care and how multiple mentoring relationships motivated them to become competent bedside clinicians. They described how the mentors' actions enabled them to deal with negative feelings, which increased their confidence, comfort and competence with clinical skills. CONCLUSIONS: Clinical skills improved when a novice model C clinical nurse leader worked with multiple mentors. The qualitative data did not show that the model C clinical nurse leaders needed different mentoring relationships than traditionally educated nurses. IMPLICATION FOR NURSING MANAGEMENT: The results suggest multiple mentors should be used to develop the clinical competences of novice model C clinical nurse leaders.

Effect of mentoring on professional values in model C clinical nurse leader graduates.

BACKGROUND: Nursing graduates acquire their nursing values by professional socialization. Mentoring is a crucial support mechanism for these novice nurses, yet little is known about the model C clinical nurse leader graduate and the effects of mentoring. AIM: This investigation examined how mentoring affected the development of professional nursing values in the model C clinical nurse leader graduate. METHODS: A longitudinal design was used to survey model C clinical nurse leader graduates before and after graduation to determine how different types of mentoring relationships influenced professional values. Demographic surveys documented participant characteristics and the Nurses Professional Values Scale - Revised (NPVS-R) assessed professional nursing values. RESULTS: Mean NPVS-R scores increased after graduation for the formally mentored participants, while the NPVS-R scores decreased or remained unchanged for the other mentoring groups. However, no significant difference was found in NPVS-R scores over time (p = .092) or an interaction between the NPVS-R scores and type of mentoring relationships (p = .09). CONCLUSION: These results suggest that model C clinical nurse leader graduate participants experiencing formal mentoring may develop professional nursing values more than their colleagues. IMPLICATIONS FOR NURSING MANAGEMENT: Formal mentoring relationships are powerful and should be used to promote professional values for model C clinical nurse leader graduates.

Factors Related to School Nurse Workload.

Recognizing the need for a school nurse workload model based on more than the number of students in a caseload, the National Association of School Nurses issued recommendations related to measuring school nurse workload. Next, a workforce acuity task force (WATF) was charged with identifying the steps needed to further the recommendations. As a first step, the WATF focused on identifying existing literature and practices related to school nurse workload. The purpose of this article is to synthesize and categorize the factors that were identified, delineate sources for collecting and retrieving these factors, and make recommendations for clinicians and researchers interested in developing instruments to measure school nurse workload.

Cutaneous polyarteritis nodosa localized to a region of lymphedema secondary to Streptococcus viridans cellulitis and multiple surgeries.

Cutaneous polyarteritis nodosa (CPAN) is a chronic, indolent, single organ arteritis that generally presents with lower extremity nodules and/or livedo racemosa, accompanied by malaise and arthralgias. CPAN is often triggered by infection, commonly Group A streptococcal species, and is considered an autoimmune reaction. Scarring from surgery and obliterative lymphangiitis from bacterial cellulitis are the causes of lymphedema. Lymphedematous skin is predisposed to autoimmune disorders. Herein we report a 53-year-old woman who developed CPAN restricted to a localized area of the right upper arm-shoulder that had undergone multiple surgeries, complicated by episodes of Streptococcus viridans cellulitis. Clinically, a 15 cm diameter plaque exhibited violaceous, reticulate margins, subtle papules and nodules and central livedo racemosa. Biopsy showed numerous foci of arteritis in active, subacute and reparative stages. In addition, a broad zone of fibrosis replaced the deep dermis-subcutis zone and harbored numerous dilated lymphatic vessels scar lymphedema. Treatment consisted of high potency topical corticosteroids under occlusion; remission after 3 months therapy and follow-up. CPAN primarily affects the lower legs, a region of frequently affected by phlebolymphedema. This report of CPAN localized to an area of scar lymphedema underscores the importance of lymphatic function in the pathogenesis of CPAN.

The use of change theory to facilitate the consolidation of two diverse Bachelors of Science in Nursing programs.

BACKGROUND: Consolidation of resources, programs, and even universities are measures that university systems consider for economic reasons. The transformation and restructuring of two diverse nursing programs utilized an organizational change tool to guide the consolidation efforts. PURPOSE: Insights on how to use an organizational change model and lessons learned are shared for higher education units that may face consolidation. METHODS: The ADKAR Change Management Model, one of many organizational change resources, was advantageous in consolidating two diverse nursing programs when two universities were mandated to become one. CONCLUSIONS: Change is inevitable yet when faced with transition and transformation, thoughtful and strong, committed leaders who portray open transparent communication are an absolute requirement for sustained change. To guide the process, the ADKAR Change Management Model is an insightful and worthwhile resource.

BOOMR: Better Coordinated Cross-Sectoral Medication Reconciliation for Residential Care.

There is evidence that medication errors often arise during the transition of residents from acute care to long-term care (LTC) homes due to lapses in communication and documentation. Better Coordinated Cross-Sectoral Medication Reconciliation (BOOMR) is an integrated practice change improving medication safety during patient transitions through the health system. Our Medication Reconciliation (MedRec) redesign improved patient engagement using "the patient's story," increased quality of information, workflow efficiency and reduced unnecessary medications. Using progressive initiatives, we showed cost savings to the system proving value for quality with sustainable results since January 2015.

Development of an International School Nurse Asthma Care Coordination Model.

AIM: To identify and compare how school nurses in Reykjavik, Iceland and St. Paul, Minnesota coordinated care for youth with asthma (ages 10-18) and to develop an asthma school nurse care coordination model. BACKGROUND: Little is known about how school nurses coordinate care for youth with asthma in different countries. DESIGN: A qualitative descriptive study design using focus group data. METHODS: Six focus groups with 32 school nurses were conducted in Reykjavik (n = 17) and St. Paul (n = 15) using the same protocol between September 2008 and January 2009. Descriptive content analytic and constant comparison strategies were used to categorize and compare how school nurses coordinated care, which resulted in the development of an International School Nurse Asthma Care Coordination Model. FINDINGS: Participants in both countries spontaneously described a similar asthma care coordination process that involved information gathering, assessing risk for asthma episodes, prioritizing healthcare needs and anticipating and planning for student needs at the individual and school levels. This process informed how they individualized symptom management, case management and/or asthma education. School nurses played a pivotal part in collaborating with families, school and healthcare professionals to ensure quality care for youth with asthma. CONCLUSIONS: Results indicate a high level of complexity in school nurses' approaches to asthma care coordination that were responsive to the diverse and changing needs of students in school settings. The conceptual model derived provides a framework for investigators to use in examining the asthma care coordination process of school nurses in other geographic locations.

School Health Services for Children With Special Health Care Needs in California.

Children with special health care needs (CSHCN) are at risk for school failure when their health needs are not met. Current studies have identified a strong connection between school success and health. This study attempted to determine (a) how schools meet the direct service health needs of children and (b) who provides those services. The study used the following two methods: (a) analysis of administrative data from the California Basic Educational Data System and (b) a cross-sectional online survey of 446 practicing California school nurses. Only 43% of California's school districts employ school nurses. Unlicensed school personnel with a variety of unregulated training provide school health services. There is a lack of identification of CSHCN, and communication barriers impair the ability to deliver care. Study results indicate that California invests minimally in school health services.

The development and implementation of an interdisciplinary on-line academic course using a life course perspective.

The University of Wisconsin-Madison Pediatric Pulmonary Center (UW PPC) provides interdisciplinary leadership training for graduate students and postgraduate professionals. The training includes a three-credit on-line course entitled Interdisciplinary Care of Children with Special Health Care Needs. This paper describes the course, the content and organization of which was guided by the life course perspective (LCP). The UW PPC team used the LCP to guide course organization, content development, and evaluation approaches. UW PPC trainees took responsibility for content areas, performed literature reviews and reviews of resources, and suggested student activities. Course content was focused on the child with special health care needs (CSHCN) embedded in contextual environments of family, community, culture, and larger social and public policy arenas. The content included three case-study videos that followed a child with cystic fibrosis from birth to age 18. Key concepts of the LCP were woven in throughout the videos and other course materials. Emphasis was on representing development of the individual during critical/sensitive periods and on social determinants of health. At semester's end, qualitative and quantitative student evaluation results were very positive for all areas of the course. The final course paper, organized similarly to course modules, synthesized all aspects of the course. A successful paper included LCP concepts woven throughout to show integration of course content. The LCP provided a useful framework for course organization and content, and served as a lens through which students came to understand the care needs of CSHCN and their families. A course such as this can serve the important goal of educating future maternal child health professionals in using the LCP to understand how multiple determinants of health interact across the life span to produce health outcomes in this population.

The Prevalence and Association of Different Uropathogens Detected by M-PCR with Infection-Associated Urine Biomarkers in Urinary Tract Infections.

Background: Many emerging uropathogens are currently identified by multiplex polymerase chain reaction (M-PCR) in suspected UTI cases. Standard urine culture (SUC) has significantly lower detection rates, raising questions about whether these organisms are associated with UTIs and truly cause inflammation. Objective: To determine if microbes detected by M-PCR were likely causative of UTI by measuring inflammatory biomarkers in the urine of symptomatic patients. Design Setting and Participants: Midstream voided urine was collected from subjects ≥60 years presenting to urology clinics with symptoms of UTI (n = 1132) between 01/2023 and 05/2023. Microbe detection was by M-PCR and inflammation-associated biomarker (neutrophil gelatinase-associated lipocalin, interleukin 8, and interleukin 1ß) was by enzyme-linked immunosorbent assay. Biomarker positivity was measured against individual and groups of organisms, E. coli and non-E. coli cases, emerging uropathogens, monomicrobial and polymicrobial cases. Outcome Measurements and Statistical Analysis: Distributions were compared using 2-sample Wilcoxon Rank Sum test with 2-tailed p-values < 0.05 considered statistically significant. Results and Limitations: M-PCR was positive in 823 (72.7%) specimens with 28 of 30 (93%) microorganisms/groups detected. Twenty-six of twenty-eight detected microorganisms/groups (93%) had ≥2 biomarkers positive in >66% of cases. Both non-E. coli cases and E. coli cases had significant biomarker positivity (p < 0.05). Limitations were that a few organisms had low prevalence making inferences about their individual significance difficult. Conclusion: The majority of microorganisms identified by M-PCR were associated with active inflammation measured by biomarker positivity, indicating they are likely causative of UTIs in symptomatic patients. This includes emerging uropathogens frequently not detected by standard urine culture.

Refugees' Care Experiences, Self-Reported Health Outcomes and Transition to Mainstream Health Care After One Year at the Refugee Engagement and Community Health (REACH) Clinic.

This study reports how refugees experienced care at an integrated clinic during their first year in Canada and how they transitioned to a community physician. A survey was completed by 75 Government Assisted Refugees followed at the REACH clinic between 2018 and 2020; 16 agreed to an additional interview. Regression modelling explored the relationship between "perceived health status at one year" and several independent variables. Qualitative thematic analysis provided context. Tailored access to care and enhanced communication through interpretation contributed to satisfaction with clinic services. A significant positive relationship was found between their perceived health status and frequency of visits (p < 0.042), and "doctors' advice about how to stay healthy" (p < 0.039). Interview findings highlighted the important role of settlement agencies, timing for a successful transition and physicians' support resources. While refugees benefit from attending integrated clinics, these should also prepare the care transition to community physicians. Targeted government funding and continued medical education could enhance refugees' transition experience.

Implementing the ACHIEVE model to prevent and reduce chronic disease in rural Klickitat County, Washington.

BACKGROUND: In the United States, 133 million people live with 1 or more chronic diseases, which contribute to 7 of 10 deaths annually. To prevent and reduce the prevalence of chronic diseases, the National Association of County and City Health Officials (NACCHO) provided technical assistance and funding to 33 local health departments in Washington State, including the Klickitat County Health Department (KCHD), to implement the Action Communities for Health, Innovation, and Environmental Change (ACHIEVE) model. COMMUNITY CONTEXT: Klickitat County residents experience higher rates of obesity and overweight than people living in urban areas in the state. KCHD applied the ACHIEVE model to accomplish 2 objectives: 1) to engage the community in community health assessment, action plan development for chronic disease prevention, and implementation of the plan and 2) to work with targeted sectors to promote worksite wellness and to establish community gardens and bicycling and walking trails. METHODS: KCHD convened and spearheaded the Healthy People Alliance (HPA) to complete a community assessment, develop a community action plan, implement the plan, and evaluate the plan's success. OUTCOMES: KCHD, working with HPA, accomplished all 5 phases of the ACHIEVE model, expanded a multisector community coalition, developed Little Klickitat River Trail and 3 community gardens, and created and promoted a worksite wellness toolkit. INTERPRETATION: Assistance and training that NACCHO provided through ACHIEVE helped the KCHD engage nontraditional community partners and establish and sustain a community coalition.

The international school nurse asthma project: barriers related to asthma management in schools.

AIM: This article is a report of an international study of barriers to asthma care from the perspectives of school nurses in Reykjavik, Iceland and St. Paul, Minnesota, in the context of their schools, communities and countries. BACKGROUND: Globally, asthma affects the health and school performance of many adolescents. School nurses play a key role by providing care to adolescents with asthma in school settings. Understanding universal barriers to asthma management in schools is important for developing interventions that are effective in multiple societal contexts. DESIGN: Exploratory, descriptive study. METHODS: Parallel studies were conducted from September 2008-January 2009, through six focus groups among school nurses (n = 32, in Reykjavik n = 17 and St. Paul n = 15) who were managing asthma in adolescents. Focus groups were audio-recorded and transcribed verbatim in English or Icelandic. The Icelandic transcripts were translated into English. Descriptive content analytic techniques were used to systematically identify and categorize types of barriers to asthma care. RESULTS: School nurses in both countries identified common barriers, such as time constraints, communication challenges and school staff barriers. The primary difference was that St. Paul school nurses identified more socio-economic and health access barriers than school nurses in Reykjavik. CONCLUSION: Greater cultural and linguistic diversity and socio-economic differences in the student population in St. Paul and lack of universal healthcare coverage in the US contributed to school nurses' need to focus more on asthma management than school nurses in Reykjavik, who were able to focus more on asthma prevention and education.

Elevated UTI Biomarkers in Symptomatic Patients with Urine Microbial Densities of 10,000 CFU/mL Indicate a Lower Threshold for Diagnosing UTIs.

The literature lacks consensus on the minimum microbial density required for diagnosing urinary tract infections (UTIs). This study categorized the microbial densities of urine specimens from symptomatic UTI patients aged ≥ 60 years and correlated them with detected levels of the immune response biomarkers neutrophil gelatinase-associated lipocalin (NGAL), interleukin-8 (IL-8), and interleukin-1-beta (IL-1ß). The objective was to identify the microbial densities associated with significant elevation of these biomarkers in order to determine an optimal threshold for diagnosing symptomatic UTIs. Biobanked midstream voided urine samples were analyzed for microbial identification and quantification using standard urine culture (SUC) and multiplex-polymerase chain reaction (M-PCR) testing, while NGAL, IL-8, and IL-1ß levels were measured via enzyme-linked immunosorbent assay (ELISA). NGAL, IL-8, and IL-1ß levels were all significantly elevated at microbial densities ≥ 10,000 cells/mL when measured via M-PCR (p < 0.0069) or equivalent colony-forming units (CFUs)/mL via SUC (p < 0.0104) compared to samples with no detectable microbes. With both PCR and SUC, a consensus of two or more elevated biomarkers correlated well with microbial densities > 10,000 cells/mL or CFU/mL, respectively. The association between ≥10,000 cells and CFU per mL with elevated biomarkers in symptomatic patients suggests that this lower threshold may be more suitable than 100,000 CFU/mL for diagnosing UTIs.

Comparison Shows that Multiplex Polymerase Chain Reaction Identifies Infection-associated Urinary Biomarker-positive Urinary Tract Infections That Are Missed by Standard Urine Culture.

Background: Multiplex polymerase chain reaction (M-PCR) has increased sensitivity for microbial detection compared with standard urine culture (SUC) in cases diagnosed as urinary tract infections (UTIs), leading to questions whether detected microbes are likely causative of UTIs or are incidental findings. Objective: To compare infection-associated biomarker levels against M-PCR and SUC results in symptomatic cases with a presumptive diagnosis of a UTI by a urologist. Design setting and participants: Participants were ≥60 yr old and presented to urology clinics between January and April 2023 with symptoms of UTIs (n = 583). Urine microbial detection was by M-PCR and SUC. Three infection-associated biomarkers (neutrophil gelatinase-associated lipocalin, interleukin-8, and interleukin-1ß) were measured by enzyme-linked immunosorbent assay. Symptomatic cases with elevated biomarkers, detection of uropathogens, and a specialist clinical diagnosis of a UTI were considered definitive UTI cases. Outcome measurements and statistical analysis: Distributions were compared using two-sample Wilcoxon rank sum test, with two-tailed p values of <0.05 considered statistically significant. Results and limitations: In cases with M-PCR-positive/SUC-negative results (n = 80), all median biomarker levels were significantly higher (p < 0.0001) than in cases with M-PCR-negative/SUC-negative results (n = 107). Two or more biomarkers were positive in 76% of M-PCR-positive/SUC-negative specimens. Limitation was an inability to examine associations between each individual organism and inflammation. Conclusions: A significant number of M-PCR-positive/SUC-negative cases had elevated levels of infection-related urinary biomarkers, especially when infection was caused by organisms other than Escherichia coli. This is a strong indication that microbes detected by M-PCR, which would be missed by SUC, are associated with UTIs. Patient summary: We compared infection-associated biomarkers in patients diagnosed with urinary tract infections (UTIs) against the detection of microorganisms by standard urine culture (SUC) and multiplex polymerase chain reaction (M-PCR). We found that most patients with microorganisms detected by M-PCR, which were missed by SUC, had elevated markers of inflammation, indicating that these organisms were likely causative of UTIs.

Emerging and Fastidious Uropathogens Were Detected by M-PCR with Similar Prevalence and Cell Density in Catheter and Midstream Voided Urine Indicating the Importance of These Microbes in Causing UTIs.

Introduction: This study compared microbial compositions of midstream and catheter urine specimens from patients with suspected complicated urinary tract infections to determine if emerging and fastidious uropathogens are infecting the bladder or are contaminants. Methods: Urine was collected by in-and-out catheter (n = 1000) or midstream voiding (n = 1000) from 2000 adult patients (≥60 years of age) at 17 DispatchHealth sites across 11 states. The two groups were matched by age (mean 81 years), sex (62.1% female, 37.9% male), and ICD-10-CM codes. Microbial detection was performed with multiplex polymerase chain reaction (M-PCR) with a threshold for "positive detection" ≥ 10,000 cells/mL for bacteria or any detection for yeast. Results were divided by sex. Results: In females, 28 of 30 microorganisms/groups were found by both collection methods, while in males 26 of 30 were found by both. There were significant overlaps in the detection and densities of classical uropathogens including Escherichia coli, Enterococcus faecalis, and Klebsiella pneumoniae, as well as emerging uropathogens including Actinotignum schaalii and Aerococcus urinae. In females, detection rates were slightly higher in midstream voided compared to catheter-collected (p = 0.0005) urine samples, while males showed the opposite trend (p < 0.0001). More polymicrobial infections were detected in midstream voided compared to catheter-collected samples (64.4% vs 45.7%, p < 0.0001) in females but the opposite in males (35.6% vs 47.0%, p = 0.002). Discussion: In-and-out catheter-collected and midstream voided urine specimens shared significant similarities in microbial detections by M-PCR, with some differences found for a small subset of organisms and between sexes. Conclusion: Non-invasive midstream voided collection of urine specimens for microbial detection and identification in cases of presumed UTI does not result in significantly more contamination compared to in-and-out catheter-collected specimens. Additionally, organisms long regarded as contaminants should be reconsidered as potential uropathogens.

Education and information for practicing school nurses: which technology-supported resources meet their needs?

School nurses care for children with a variety of health-related conditions and they need information about managing these conditions, which is accessible, current, and useful. The goal of this literature review was to gather and synthesize information on technology-supported resources and to determine which met the educational needs of school nurses. Successful online educational programs were interactive and self-directed. The most common barriers were lack of time to find educational information, lack of knowledge about computers, technology, the Internet and specific programs, and lack of administrative support from school officials to use technology to access information and evidence for practice. Recommendations for successful use of technology to meet practicing school nurse's educational needs are offered.
