Lipoprotein (a) testing patterns among subjects with a measured lipid panel: The Mayo Clinic experience

ObjectiveLipoprotein(a) [Lp(a)] has been associated with Atherosclerotic Cardiovascular Disease (ASCVD). Approximately 20 % of the population has elevated Lp(a). Despite its well-recognized role in ASCVD, universal screening remains controversial. The aim of our study is to investigate laboratory testing patterns for Lp(a) in subjects screened with a standard lipid panel at a large tertiary referring US institution. MethodsData were retrospectively collected at Mayo Clinic from the Mayo Data Explorer (MDE). Subjects were included if they had a lipid panel measured between May 1, 2022, and April 30, 2023. Demographic data, Lp(a) measurements, statins and aspirin prescription and ASCVD events which occurred at any time in the life of a subject were recorded along with respective dates. The cumulative number of Lp(a) laboratory test orders were also tallied from 1994 to 2023 independently of the lipid panel requests. ResultsBetween May 1, 2022, and April 30, 2023, 257,225 subjects had a lipid panel ordered. Of these, only 386 (0.15 %) had Lp(a) tested within 1 year of the lipid panel, while 2406 (0.94 %) had Lp(a) tested at any time. Lp(a) was tested more frequently in males (67 %) and in subjects who developed Myocardial Infarction (MI) at any time (12 %). Following Lp(a) results, there was no significant change in statin or aspirin prescription associated with Lp(a) levels. Secondary prevention was the main setting for ordering Lp(a) testing, and there was no change in this trend throughout the years. ConclusionsTesting rates for Lp(a) in the general population are low and the main setting remains secondary prevention. Women are less tested than men. When Lp(a) is found to be elevated, often times there is no change in patient management to mitigate the ASCVD risk.

Changes in Acute Care Pharmacist Prescribing and Laboratory Ordering over Time: CAPLET Study.

In Alberta, pharmacists may obtain additional prescribing authorization (APA) and a practice identification number (PRAC-ID) for ordering laboratory tests. Pharmacists working within Alberta Health Services were mandated by the employer to attain APA by 2018, whereas laboratory ordering has been in place since 2009. Five acute care sites within the Calgary Zone had a computerized provider order entry (CPOE) system that allowed tracking of these activities. To describe changes in prescribing and laboratory ordering by acute care pharmacists over time and to compare these activities across hospitals, sites, and specialty teams. A retrospective, descriptive review of acute care pharmacist orders for medications and laboratory tests was completed using data from the CPOE system for the period 2018 to 2021. Over the study period, the rates of prescribing and laboratory ordering by pharmacists increased by 67.5% (from 1423 to 2383 per full-time equivalent [FTE]) and by 5.5% (from 235 to 248 per FTE), respectively. Pharmacists at the 5 hospitals increased their prescribing rates during that time (by proportions ranging from 7% to 176%). Cardiology, intensive care, and mental health teams had the largest increases in prescribing rates, whereas mental health, hospitalist, and intensive care teams had the greatest increases in rates of laboratory ordering. In each year of the study, the most frequently ordered medication for adult patients was vancomycin, and the most frequently ordered laboratory test was measurement of vancomycin before dose administration. The proportion of medication orders conveyed verbally decreased from 60.0% to 47.4% over the study period. The application of expanded scope of practice increased among acute care pharmacists, to a greater extent for prescribing than for laboratory ordering; however, the proportion of verbal medication orders remains high, a situation that should be addressed to improve patient safety. This study showed that prescribing and laboratory ordering are complementary, given that the top medications and laboratory tests were frequently related. The results of this study can be used for practice development and as the basis for further research within an expanded CPOE system.

A-184 Evidence-based Test Utilization: Test Ordering Patterns in Functional Medicine and Community Clinics, and Implications for Laboratory Stewardship

Abstract Background Functional Medicine Physicians (FMPs) use a holistic approach to identify and address “the root cause of a disease”. These physicians routinely order laboratory tests that are not supported by clinical suspicion and practice guidelines (i.e., Centers for Disease Control and Prevention Laboratory Medicine Best Practices, and local diagnostic algorithms) and are unnecessarily duplicative, with inappropriate testing patterns. Ordering unnecessary tests does not improve diagnosis; indeed, 5% of disease-free patients falsely test positive for a given diagnostic test. Test overutilization increases the rate of false positives, leading to unnecessary medical follow-ups, compromised patient care, and financial constraints on the healthcare system. The objective of this study is to: 1) Compare test ordering patterns between FMPs and General Practitioners (GPs) to identify disparities and opportunities for laboratory stewardship improvements. 2) Analyze the potential factors impacting test utilization in areas served by FMPs, 3) investigate the proper approach to improve test utilization. Methods Using our laboratory’s information system, we conducted a retrospective study spanning from January 2022 to December 2022 to assess testing patterns by 15 FMPs in Southern Alberta, comparing them to those of randomly selected community GPs within the same geographical region. A query was executed to retrieve data on the top 50 chemistry tests ordered by functional medicine clinics and community clinics. These tests were further categorized into six groups: general chemistry, endocrinology, immunology, trace elements, toxic metals, and vitamins. Data analysis included determining the geographical locations of functional medicine clinics and assessing the socioeconomic status of their patient populations. Additionally, the percentage of abnormal test results were calculated for both functional medicine clinic and community clinics. Furthermore, the average cost of tests per patient, per physician, and per clinic was computed to evaluate the financial implications of testing practices. Results Our preliminary results showed significant variability in test ordering practices among FMPs, with potential implications for patient care and healthcare costs. Most tests ordered by FMPs were normal (94%), suggesting a need for further scrutiny regarding the necessity and appropriateness of these tests. A notable trend observed was the disproportionate preference of FMPs for expensive tests, including hormones, vitamins, and toxic metals. Our analysis reveals that the cost per reportable test from FMPs was four times higher compared to the tests ordered by GPs. Furthermore, on average, functional medicine clinics in urban areas ordered around 60% more tests annually compared to their rural counterparts. Conclusions Our preliminary findings clearly show a need to monitor the testing behavior more carefully by the functional medicine clinics. The data from this study will be shared with the physicians practicing functional medicine in Alberta. Strategies to improve the test utilization and patient care include educating the functional medicine doctors and provincial healthcare authorities about the appropriate test utilization and the impact of inappropriate use of lab on patient care. In addition, using algorithms for test ordering will be used if the pattern of inappropriate testing continues.

Understanding Workflow Nuances That Affect the Use of a Laboratory Test Ordering Support Tool.

The "Emergency Department Pathology Order Support Tool" (ED-POST) is an electronic laboratory test ordering decision support tool that aims to decrease variation in test ordering practices. As part of a larger project on the co-design, development, and evaluation of ED-POST, this study aimed to explore the workflow nuances that might affect the intended use of the digital decision support tool. Semi-structured, in-depth interviews were conducted with 15 ED clinicians involved in the laboratory test ordering process across the development and evaluation phases of ED-POST. Participants identified the expanded role of registered nurses in test ordering and the practice of ordering tests that are outside the ED's scope as contextual characteristics that can affect the use and perceived utility of the proposed ED-POST tool. Reconciling "work-as-imagined" with "work-as-done" in the design and development of electronic interventions is important in achieving interventions to improve the safe and effective use of pathology tests.

Atypical bacteria in pediatric sickle cell patients with acute chest syndrome

Abstract The purpose of this study was to quantify the frequency of Mycoplasma pneumoniae or Chlamydia pneumoniae in a large contemporary real-world data set. This was a retrospective database analysis utilizing data collected from the TriNetX Global Collaborative Network, which provided access to electronic medical records for patients from 78 different healthcare organizations. Data were collected using ICD-10 codes and laboratory test order codes from TriNetX. Inclusion criteria are patients less than or equal to 18 years old with SCD with an ICD-10 code for ACS or pneumonia. Patients were included in the primary outcome analysis if they had a laboratory code for a rapid diagnostic test for M. pneumoniae and/or C. pneumoniae performed by either nasal swab or respiratory culture. There were 6762 pediatric sickle cell patients with an ICD-10 code for ACS or pneumonia identified. Of these patients, only 16.3% were tested for M. pneumoniae and 17.1% were tested for C. pneumoniae. The patients who were tested for these atypical organisms were further investigated for positivity on rapid diagnostic testing, and the positivity rate in these patients was 1.1% for M. pneumoniae and less than or equal to 0.87% for C. pneumoniae. Pediatric patients with ACS who were tested for M. pnuemoniae and C. pnuemoniae had low rates of positivity for these organisms. Most of these patients did not have recorded microbiologic testing, showing evidence of a large underutilization of diagnostic tools available that could assist with de-escalation of antibiotics.

The Effect of a Mobile-Based Intervention on Physicians' Laboratory Test Ordering Behavior.

Utilizing digital tools, particularly mobile technologies, is viewed as a critical strategy to improve the efficient use of healthcare services. Quasi-experimental research was carried out with residents to investigate the impact of mobile-based feedback (MBF) on residents' laboratory test ordering behavior.

Improving Compliance With Evidence-Based Laboratory Testing Recommendations and Monitoring Associated Patient Outcomes.

A team comprising nursing, medical staff, and administrative leaders at an urban academic orthopedic hospital in the northeastern United States sought to revise a preoperative laboratory testing protocol based on evidence and practice guidelines. The goal was to decrease unnecessary tests by 20% without negatively affecting patient outcomes. After adding the revised protocol to the electronic health record, audits revealed that the target goal was not met and additional strategies were implemented, including educational webinars for surgeon office personnel who ordered tests, additional webinars for advanced practice professionals, and the creation of scorecards to track surgeons' progress. Overall, a downward trend in the ordering of unnecessary laboratory tests for patients without identified risks was observed, but a 20% reduction was not achieved. Surgical complications during the project were not associated with laboratory tests. Clinicians continue to use the revised preoperative laboratory testing protocol at the facility.

Adopting a systems engineering approach to a feasibility study of a sidings development at the Midsomer Norton railway station

It is planned to reopen Midsomer Norton railway station, which is a station on the Somerset & Dorset Heritage Railway Line, to traffic. As a first step, Midsomer Norton will be a terminus, and it is proposed to build sidings and a depot for the trains that terminate there. However, a ground investigation is essential before commencing construction of the sidings and the depot, as this is a vital part of any civil engineering process. The behaviour of the ground must be known in order for a structure to be supported by it; therefore, data from the ground investigation are used as reference for any kind of structure development. This study covers a site investigation that includes a desk study, walkover survey, sampling and laboratory testing in order to ascertain the feasibility of a suitable design. Moisture content testing, liquid limit and plastic limit tests, standard compaction testing, shear vane tests, and triaxial compression tests were carried out to determine the soil characteristics and to analyse the soil behaviour. A strong recommendation was made to follow a systems engineering approach in the construction phase, as well as in the design stage. The dependability of the system is ensured by the good use of V – process of systems engineering.

Analyzing laboratory test utilization trends in belgian primary care: a decade of insights with international perspectives

BackgroundClinical laboratory testing, essential for medical diagnostics, represents a significant part of healthcare activity, influencing around 70% of critical clinical decisions. The automation of laboratory equipment has expanded test menus and increased efficiency to meet the growing demands for clinical testing. However, concerns about misutilization remain prevalent. In Belgium, primary care has seen a dramatic increase in lab test usage, but recent utilization data is lacking.MethodsWe conducted a comprehensive retrospective analysis of laboratory test utilization trends within the primary care settings of Belgium over a ten-year period, spanning from 2012 to 2021, incorporating a vast dataset of 189 million test records for almost 1.5 million persons. This was the first study to integrate the metadata from both the INTEGO & THIN databases, which are derived from the two major electronic medical record (EMR) systems used in primary care in Belgium, providing a comprehensive national perspective. This research provides crucial insights into patient-level patterns, test-level utilization, and offers international perspectives through comparative analysis.ResultsWe found a subtle annual increase in the average number of laboratory tests per patient (ranging from approximately 0.5-1%), indicative of a deceleration in growth in laboratory test ordering when compared to previous decades. We also witnessed stability and consistency of the most frequently ordered laboratory tests across diverse patient populations and healthcare contexts over the years.ConclusionsThese findings emphasize the need for continued efforts to optimize test utilization, focusing not only on tackling overutilization but on enhancing the diagnostic relevance of tests ordered. The frequently ordered tests should be prioritized in these initiatives to ensure their continued effectiveness in patient care. By consolidating extensive datasets, employing rigorous statistical analysis, and incorporating international perspectives, this study provides a solid foundation for evidence-based strategies aimed at refining laboratory test utilization practices. These strategies can potentially improve the quality of healthcare delivery while simultaneously addressing cost-effectiveness concerns in healthcare.

Disparities in satisfaction among insured and uninsured adult outpatient department service users in Southern Ethiopia, 2022: a comparative cross-sectional study

BackgroundPatient satisfaction is a critical measure of the quality of healthcare services provided by healthcare facilities. However, very few studies, particularly in Ethiopia, which includes the study area, have specifically examined these discrepancies among people who use outpatient care. In this study, satisfaction levels and associated factors were compared between insured and uninsured patients receiving outpatient services at public health institutions in Hadiya Zone, southern Ethiopia.MethodsA facility-based comparative cross-sectional study design was employed on 630 patients using multistage and systematic random sampling. Data were collected using a pretested and structured interviewer-administered questionnaire. Results of the analysis were presented in text, tables, and graphs as appropriate. Multivariable logistic regression was used to predict associations between predictors and the outcome variable. Statistical significance was declared at p-value < 0.05.ResultsOverall, 344(55.48%) patients were satisfied with the service they received, of which 206(65.8%) out of 313 with a 95% CI [60.7–71.2%] were insured and 138(44.95%) out of 307 with a 95% CI [39.4–5.1%] were uninsured. Among insured patients, factors associated with higher satisfaction included having a family size less than five members [AOR = 3.3, 95% CI; 1.5, 7.4], perceived fair waiting time to be seen[AOR = 2.35, 95% CI; 1.02, 5.5], perceived short waiting time to be seen[AOR = 8.12, 95% CI; 1.6, 41.3], having all ordered laboratory tests available within the facility[AOR = 7.89, 95% CI; 3.5, 17.5], having some ordered laboratory tests within the facility[AOR = 2.97, 95% CI; 1.25, 7.01] having all prescribed medications available within the facility[AOR = 16.11, 95% CI; 6.25, 41.5], having some prescribed medications available within the facility[AOR = 13.11, 95% CI; 4.7, 36.4]. Among non-insured patients, factors associated with higher satisfaction included urban residency, a fair and short perceived time to be seen, having ordered laboratory tests within the facility, and having prescribed drugs within the facility.ConclusionThis study identified lower overall satisfaction, particularly among uninsured patients. Enrollment in the CBHI program significantly impacted satisfaction, with both groups reporting lower levels compared to enrollment periods. Access to essential services, wait times, and socio-demographic factors identified as associated factors with patient satisfaction regardless of insurance status.

Experiences and observations from a care point for displaced Ukrainians: a community case study in Antwerp, Belgium.

A total of 7,307 Ukrainian refugees moved to Antwerp, Belgium, during the study period (01 April 2022 to 31 December 2022). The city's administration set up three care centers where these people were introduced to the Belgian primary care system, a medical file was created, and acute/preventive/chronic care was delivered. This community case study analyzes the organization and contents of care and reflects upon its meaning for the mainstream healthcare system. This is an observational study using routine electronic medical record data to measure the uptake of care. For a sample of 200 subjects, a retrospective chart review was conducted. All refugees with a medical file at one of the three participating care centers were included. For the observational study, 2,261 patients were reached (30% of the potential users), and 6,450 contacts were studied. The nurses (including midwives) conducted 4,929 out of 6,450 (76%) of all consultations, while the general practitioners (GPs) conducted 1,521 out of 6,450 (24%). Of the nurse consultations, 955 (19%) were followed by another nurse consultation and 866 (18%) by a GP consultation. In the structured case reviews, most contacts were concerned with acute problems (609 out of 1,074, 57%). The most prevalent reasons for encounters and diagnoses were typical primary care issues. The nurses were able to manage half of the cases independently (327, 55%), referred 37% (217) of cases to the GP, and consulted a GP (live, by telephone, or a dedicated app) for 8% (48) of cases. GPs mostly prescribed drugs, referred to a medical specialist, and advised over-the-counter drugs, while nurses more often advised over-the-counter drugs (mostly paracetamol, nose sprays, and anti-inflammatory drugs), provided non-medical advice, or ordered laboratory tests. The medical care points delivered mostly typical acute primary care in this first phase, with a key role for nurses. The care points did not sufficiently take up chronic diseases and mental health problems. These results will inform policymakers on the use of primary care centers for newly arriving patients in times of a large influx. A nurse-first model seems feasible and efficient, but evaluation of safety and quality of care is needed. Once the acute phase of this crisis fades away, questions about the comprehensiveness, continuity, and integration of care for migrants remain relevant.

Clinical impact and financial feasibility of remote oncology pharmacists' roles in community oncology practices.

1545 Background: The clinical and financial impact of oncology-trained pharmacists in the community oncology setting has not been well documented. The US Oncology Network has introduced a novel remote oncology pharmacist model which provides clinical services to oncology community practices to alleviate the burden on oncologists, enhance patient care, and improve workflows. Methods: Oncology-trained pharmacists remotely reviewed chemotherapy regimens across 12 community oncology practices. Pharmacists identified opportunities to modify therapy based on clinical criteria, waste reduction, and/or financial stewardship. These modifications were discussed with the treatment team or implemented in accordance with practice-approved policies. Clinical and financial metrics were tracked to assess the overall impact of the pharmacist interventions and provider time saved. Results: From January 1, 2023, through December 31, 2023, 27,938 reviews were documented for 19,962 patients. Among these reviews, the majority (14,572, 73%) required modification by the pharmacist, and many (3,005, 21%) were deemed clinically significant by the intervening pharmacist. The most common clinically significant interventions included changes to anticancer drug doses (1155, 38%), modifications to supportive care (742, 25%) and recommendations for additional monitoring (426, 14%). Across 12 practices, 63 drug-related workflow policies were implemented allowing pharmacists to autonomously auto-substitute products, order laboratory tests and adjust chemotherapy doses. These policies saved over 600 hours of physician time. Pharmacist involvement resulted in medication-related margin improvements totaling $9.3M. Practices also experienced a $4.3M reduction in the total cost of care in medication expenses. The cost of the pharmacists during this period was $1.4M, equating to a 560% return on investment compared to margin improvement. Conclusions: Community oncology practices operate within a resource-constrained model with limited access to oncology pharmacists. As invaluable members of the care team, pharmacists identified opportunities to significantly enhance clinical care by focusing on medication safety, dosing, and regimen optimization, while demonstrating a tremendous financial impact on small-scale budgets. Oncology-trained pharmacists play a vital role in alleviating care burden of the clinical team by collaboratively developing practice-approved policies and reviewing clinical orders in a high-risk patient population.

An Introduction to the Complete Blood Count for Clinical Chemists: Red Blood Cells.

The most frequently ordered laboratory test worldwide is the complete blood count (CBC). In this primer, the red blood cell test components of the CBC are introduced, followed by a discussion of the laboratory evaluation of anemia and polycythemia. As clinical chemists are increasingly tasked to direct laboratories outside of the traditional clinical chemistry sections such as hematology, expertise must be developed. This review article is a dedication to that effort.

In this primer, an introduction to platelet testing in the context of the CBC is provided with a discussion of the laboratory evaluation of platelet abnormalities including thrombocytopenia and thrombocytosis. As clinical chemists continue to be tasked to direct laboratories outside of the traditional clinical chemistry sections such as hematology, expertise must be developed. This primer is dedicated to that effort.

Enhanced cross laminated timber (ECLT) for ballistic resistant design

Cross-laminated timber (CLT), an engineered wood product, has grown in popularity in the United States over the last decade due to its ease of assembly, aesthetic appeal, and potential to serve as a sustainable and renewable alternative building material. The improved robustness of CLT over light-frame timber structures has increased its potential in force-protected infrastructure that must resist blast waves and ballistic projectile penetration, but softwood CLT is typically not sufficient to fulfill standard criteria for ballistic threats. To address these threats, enhanced CLT (ECLT) composite panels were manufactured with layers of various reinforcing materials (e.g., steel, FRP) placed between wood laminations. These panels were tested against various ballistic threats during two sets of laboratory tests in order to provide a basis for future research. The first set of testing subjected laboratory-produced Southern Yellow Pine (SYP) ECLT to 84 shots of 0.50-inch (1.27 cm) steel sphere projectiles to evaluate the performance of various reinforcing materials, layups, and fastening methods. A subsequent set of tests subjected commercially produced ECLT of steel-reinforced Spruce-Pine-Fir (South) (SPF-S) to 36 shots of NATO ammunition projectiles traveling at realistic, standard striking velocities. Except for a panel using four layers of a thin and finely woven steel hardware cloth, steel reinforcement was effective in stopping projectiles from all three types of NATO ammunition fired. Ultimately considering the results of these two sets of tests, an initial cost-benefit structure was developed and discussed to compare ECLT configurations holistically, a multi-material wood analytical model framework was established and compared to experimental results, and the first ballistic experimental database for ECLT was created.

Pharmacist certification of drug therapy modification: A survey of pharmacist‐reported practices, facilitators, and barriers in Georgia

AbstractIntroductionCollaborative drug therapy management (CDTM) allows pharmacists to assess patients, administer medications, manage and adjust medication regimens, and order laboratory tests within a defined protocol. Pharmacist CDTM may aid in preventative care and chronic condition management.ObjectivesThe primary objectives were to identify CDTM services provided by pharmacists in the state of Georgia, examine factors associated with the provision of CDTM services, and identify barriers and facilitators to CDTM service provision. The secondary objective was to assess differences in CDTM practice between pharmacists who completed a Registered Pharmacist (R.Ph.)/Doctor of Pharmacy (Pharm.D.), postgraduate year one (PGY1), or postgraduate year two (PGY2) residency.MethodsUsing the Dilman method, this cross‐sectional study invited all 134 CDTM‐licensed pharmacists in Georgia to complete a 30‐min electronic survey. Data included demographics, training, services offered, disease states managed, and perceptions regarding CDTM implementation. Descriptive statistics, Welchs analysis of variance (ANOVA), and chi‐square were conducted using SPSS v28.ResultsA total of 36 (26.9%) pharmacists completed the survey. Participants offered a median of three CDTM services. A majority offered medication therapy management (86.1%) and chronic care management (66.7%). A majority offered services for diabetes (58.3%), hyperlipidemia (55.6%), and hypertension (55.6%). There were differences in the mean ranked number of CDTM services offered between R.Ph./Pharm.D. and PGY2 groups (−11.667, p = 0.019), and the mean ranked number of disease states covered between R.Ph./Pharm.D. and PGY1 (−10.990, p = 0.029) and R.Ph./Pharm.D. and PGY2 (−12.640, p = 0.010, adjusted p‐value) groups. Reported CDTM facilitators were job requirements, expanding patient care, job satisfaction/personal advancement, and expanding professional practice. Reported challenges were continuing education, clinical/interprofessional concerns, administration issues with the board of pharmacy or individual practice site, and regulations differing from other states.ConclusionOf those with CDTM licensure, a majority offer medication therapy management and chronic care management services covering diabetes, hypertension, and hyperlipidemia. Postgraduate training may help prepare pharmacists to engage in CDTM services.

Incidence of Lyme Borreliosis in Germany: A retrospective observational healthcare claims study

Lyme borreliosis (LB) is the most common tick–borne disease in Germany. Although the incidence of LB in Germany has been assessed in several studies, those studies either used data from statutory surveillance, which frequently underreport cases, or data from health claims databases, which may overestimate cases due to non–specific LB case definitions. Here, using a more specific case definition, we describe the incidence of medically–attended LB by disease manifestation, age group, and federal state for the period 2015–2019. Both inpatient and outpatient cases were analyzed from a claims database. To be eligible for inclusion, patients were required to have an LB specific ICD–10 GM diagnosis code plus an antibiotic prescription, and for disseminated manifestations, a laboratory test order additionally. LB cases were classified as erythema migrans (EM), or disseminated disease including Lyme arthritis (LA), Lyme neuroborreliosis (LNB), and all other disease manifestations (OTH). Between 2015 and 2019, the incidence of medically–attended LB cases ranged from 195.7/100,000 population per year (95% confidence interval [CI], 191.0 – 200.5) to 254.5/100,000 population per year (95% CI, 249.0 – 260.0) per year. The majority of cases (92.2%) were EM, while 2.8% presented as LA, 3.8% as LNB, and 1.2% as OTH. For both EM and disseminated disease, the incidence peaked in children aged 5–9 years and in older adults. By federal state, the incidence of medically–attended EM ranged from 74.4/100,000 population per year (95% CI, 71.9 – 77.0) per year in Hamburg, to 394.1/100,000 population per year (95% CI, 370.7 – 417.6) per year in Saxony, whereas for medically–attended disseminated disease, the highest incidence was in Thuringia, Saxony, and Bavaria (range: 22.0 [95% CI, 19.9 – 24.0] to 35.7 [95% CI, 34.7 – 36.7] per 100,000 population per year). This study comprehensively estimated the incidence of all manifestations of medically–attended LB and showed a high incidence of LB throughout Germany. Results from the study support performing epidemiological studies in all federal states to measure the burden of LB and to invest in public health interventions for prevention.

Collaborative drug therapy modification (CDTM): Facilitators, barriers, and perceptions of individual pharmacist participation in Georgia

BackgroundGeorgia Board of Pharmacy (BOP) regulations permit pharmacists to engage in collaborative drug therapy modification (CDTM) with physicians, allowing them to perform patient assessments, adjust pharmacotherapy, and order laboratory tests. Pharmacist-led CDTM can positively affect health outcomes leading to reduced healthcare expenditures. CDTM is underutilized, with < 1% of Georgia pharmacists holding an active license to practice CDTM. Objective(s)The objective of this study was to examine CDTM licensed pharmacists’ perceptions of facilitators and barriers in providing CDTM. MethodsGeorgia-licensed CDTM pharmacists were invited to participate in a 60-minute qualitative interview. Interview questions were developed from electronic survey responses. The interview was designed to elicit information regarding perceived benefits and barriers to CDTM implementation. Guided by the Consolidated Framework for Implementation Research, thematic analysis was applied to identify themes using ATLAS.ti software to code. Themes were described qualitatively and prevalence of each was reported. ResultsNine interviews were conducted, and data saturation was achieved at interview 6. After resolution of discrepancies, 100% coding agreement was reached among 2 independent researchers. Nine themes were identified, and each was categorized as a facilitator or barrier to establishing pharmacist-led CDTM in Georgia. Themes associated with facilitating were (prevalence %) (1) practice autonomy (100), (2) personal attributes (100), (3) having support (100), and (4) institutional logistics (88). Barrier themes included issues concerning (5) the Georgia BOP (100), (6) pharmacist autonomy (88), (7) lack of provider status (88), (8) institutional restrictions (75), and (9) personal development (e.g., confidence) (22). ConclusionFacilitators to the establishment of pharmacist-led CDTM exist and pharmacists can capitalize on these to create successful CDTM programs. Barriers are varied, and it may be difficult to systematically address individual barriers such as pharmacist autonomy and personal development. Barriers associated with institutional restrictions, the Georgia BOP, and lack of provider status can likely be removed or addressed by policy.

Terato-Neuroendocrine Tumour of Testis: Review and Update

Neuro-endocrine tumours commonly emanate from intestinal and respiratory epithelium. Neuro-endocrine tumours could also on rare occasions afflict various organs of the human body. Neuro-endocrine tumour afflicting the testis is an uncommon tumour which does account for far less than one percent (&lt;1%) of all tumours of testis. To the knowledge of the author, less than 100 cases of primary neuro-endocrine tumour of the testis had been reported so far in the global literature. The reported cases of neuro-endocrine tumour of testis have ranged between 10 years and 83 years of age and the reported incidence rate had been noted to be higher within the fifth and sixth decade of life. Majority of patients who are afflicted by neuro-endocrine tumour of testis do tend to manifest with unilateral painless testicular mass. Sixteen percent (16%) of patients who are afflicted by neuro-endocrine tumour of testis do manifest with symptoms of neuroendocrine tumour syndrome. Eleven percent (11%) of primary neuroendocrine tumours of testis tend to be diagnosed initially with a contemporaneously-associated metastasis. Neuro-endocrine tumours of the testis occur as a primary testicular neuroendocrine tumour, or they may be metastatic neuroendocrine tumour to the testis with the primary tumour originating from elsewhere in the body especially from the gastrointestinal or cardiorespiratory tract system. Primary neuro-endocrine tumour of testis, could be further sub-divided into: (a) primary pure neuroendocrine tumour of testis; and (b) neuro-endocrine tumour of testis contemporaneously associated with teratoma or dermoid/epidermoid cysts. Once a neuro-endocrine tumour of testis is diagnosed, it is pivotal that clinicians should exclude a metastatic neuroendocrine tumour to the testis with the primary tumour originating from elsewhere within the human body. It has been iterated that the presence of teratomas elements within the neuro-endocrine tumour of testis does sufficiently rule out the primary site outside the testis. In order to accurately diagnose the neuro-endocrine tumour of the testis, it has been advised that it is pertinent to submit the tumour mass entirely and to look for any additional lineage of differentiation. Twenty five percent of primary neuro-endocrine tumours of testis are associated with teratoma. Histogenesis of pure neuroendocrine tumour of the testis is yet to be clarified. Two postulates had been propounded in relation to the mode origin of neuroendocrine tumour of testis including: (1) Emanation from a teratoma which is the germ cell origin postulate; (2) Emanating from argentaffin cells that are located within crypts of Lieberkühn .A study related to three pure testicular neuroendocrine tumours of testis had indicated that pure neuroendocrine tumour of testis might have different genetic background other than germ cell tumour.[11] Histopathology examination of specimens of neuro-endocrine tumour of testis has tended to demonstrate tumour cells that tend to be typified by the presence of nests of small round cells with uniform nuclei forming small acini and rosettes or sheets. The cells tend to contain eosinophilic granules within the cytoplasm and granular chromatin within the nuclei. The tumour cells do exhibit positive staining for neuroendocrine markers like chromogranin and synaptophysin as illustrated in detail in the article. Radical orchidectomy is the most adopted option of treatment; nevertheless, necessitation for the undertaking of provision of adjuvant treatment depending upon histological grading has not been clarified. Because of the possibility of development of local recurrence and or distant metastases after a long time, it is pivotal for all clinicians to carefully follow-up their patients over a long-period of time with clinical, laboratory testing and radiology-imaging testing follow-ups in order to establish early diagnosis of any local recurrence or distant metastasis to be able provide further treatment of curative intent early. There is also the possibility that neuro-endocrine tumours of testis had so far been under-reported due to mis diagnosis of the tumour upon pathology examination of the testicular tumour or the correct set of monoclonal and polyclonal antibodies had not been utilized in the immunohistochemistry study assessment of the tumours. It would be advised that all clinicians and pathologists globally should have a high index of suspicion for a neuro-endocrine tumour of testis in order to establish prompt diagnosis of the tumour and to provide appropriate assessment, treatment and follow-up of all their patients.

Utility of Vizient Clinical Data Base as a benchmarking tool for laboratory stewardship programs

Abstract Establishing an effective laboratory stewardship program across healthcare systems to improve patient care has been of growing interest. Despite general guidelines from various organizations, clear definitions for these laboratory-based quality measures, and associated benchmarks, are still lacking. Hence, we utilized Vizient® Clinical Data Base (CDB) as a tool to benchmark our institution against U.S. News and World Reports’ Honor Roll (USNW) healthcare organizations 2021-2022. We focused on inpatient laboratory testing with specific targets including mean laboratory resource units used per patient per day to obtain an overview of our institution’s overall performance, daily basic metabolic panel and CBC test ordering patterns across various service lines, and C-reactive protein (CRP) to erythrocyte sedimentation rate (ESR) order ratios compared to USNW hospitals. As one of the five institutions with the highest mean laboratory resource units used per case per day (12.7) from January 1, 2021-January 31, 2022, we investigated this further to identify tests driving this result. Of all the laboratory tests ordered, blood gas was identified at the 99th percentile compared to peers. Stratifying by service, we found cardiac surgery (17%), general medicine (15%), pulmonary/critical care (11%), neonatology (10%) and transplant (9%) services at our institution were the major contributors to blood gas orders. Investigating daily laboratory test orders (BMP, CBC) showed that our institution was at the 46th and 71st percentile overall, respectively. Further CBC analysis showed that general medicine (28%) and oncology (11%) services were the major contributors for the test volume and highest total resource units used per quarter in 2021. Assessing CRP to ESR ratio depicted that our institution’s ratio of 2.2 was lower compared to USNW hospitals’ average of 2.9, meaning ESR is likely overutilized. In conclusion, Vizient CDB can be used as a resource for benchmarking laboratory utilization patterns. It can be helpful in developing road maps and prioritizing interventions for lab stewardship programs. This study identified a general overuse of laboratory resources at the hospital compared to peers, and identified some intervention targets including blood gas testing and ESR.
