Patient Perspectives on Weight Management for Living Kidney Donation.

BACKGROUND: Living kidney donors (LKDs) with obesity have increased perioperative risks and risk of end-stage renal disease after donation. Consequently, obesity serves as a barrier to donation, as many transplant centers encourage or require weight loss before donation for obese LKD candidates. Therefore, this study sought to assess patients' perspectives on weight management strategies before donation among obese LKD candidates. We hypothesized that willingness to participate in a weight loss program may be associated with donor-recipient relationship. MATERIALS AND METHODS: Obese (BMI ≥30 kg/m2) LKD candidates evaluated at a single institution from September 2017 to August 2018 were recruited. A survey was administered to assess LKD candidates' baseline exercise and dietary habits and their interest in weight management strategies for the purpose of donation approval. Participants were grouped by relationship to the recipient (close relatives: first-degree relatives or spouses [n = 29], compared with all other relationships [n = 21]). Descriptive statistics were used to summarize the data. RESULTS: 50 of 51 obese LKD candidates who were approached completed the survey. 90% of participants expressed willingness to lose weight if necessary to become eligible for donor nephrectomy. Compared with all other LKD candidates, close relatives were more likely to be interested in combined diet and exercise programs at our institution (P = 0.01). CONCLUSIONS: Among obese LKD candidates, there was an interest in weight loss for the purposes of living kidney donation approval, particularly among close relatives of potential recipients. Future programs designed to promote weight management efforts for obese LKD candidates should be considered.

Opposing effects of Apoe/Apoa1 double deletion on amyloid-ß pathology and cognitive performance in APP mice.

UNLABELLED: ATP binding cassette transporter A1 (encoded by ABCA1) regulates cholesterol efflux from cells to apolipoproteins A-I and E (ApoA-I and APOE; encoded by APOA1 and APOE, respectively) and the generation of high density lipoproteins. In Abca1 knockout mice (Abca1(ko)), high density lipoproteins and ApoA-I are virtually lacking, and total APOE and APOE-containing lipoproteins in brain substantially decreased. As the ε4 allele of APOE is the major genetic risk factor for late-onset Alzheimer's disease, ABCA1 role as a modifier of APOE lipidation is of significance for this disease. Reportedly, Abca1 deficiency in mice expressing human APP accelerates amyloid deposition and behaviour deficits. We used APP/PS1dE9 mice crossed to Apoe and Apoa1 knockout mice to generate Apoe/Apoa1 double-knockout mice. We hypothesized that Apoe/Apoa1 double-knockout mice would mimic the phenotype of APP/Abca1(ko) mice in regards to amyloid plaques and cognitive deficits. Amyloid pathology, peripheral lipoprotein metabolism, cognitive deficits and dendritic morphology of Apoe/Apoa1 double-knockout mice were compared to APP/Abca1(ko), APP/PS1dE9, and single Apoa1 and Apoe knockouts. Contrary to our prediction, the results demonstrate that double deletion of Apoe and Apoa1 ameliorated the amyloid pathology, including amyloid plaques and soluble amyloid. In double knockout mice we show that (125)I-amyloid-ß microinjected into the central nervous system cleared at a rate twice faster compared to Abca1 knockout mice. We tested the effect of Apoe, Apoa1 or Abca1 deficiency on spreading of exogenous amyloid-ß seeds injected into the brain of young pre-depositing APP mice. The results show that lack of Abca1 augments dissemination of exogenous amyloid significantly more than the lack of Apoe. In the periphery, Apoe/Apoa1 double-knockout mice exhibited substantial atherosclerosis and very high levels of low density lipoproteins compared to APP/PS1dE9 and APP/Abca1(ko). Plasma level of amyloid-ß42 measured at several time points for each mouse was significantly higher in Apoe/Apoa1 double-knockout then in APP/Abca1(ko) mice. This result demonstrates that mice with the lowest level of plasma lipoproteins, APP/Abca1(ko), have the lowest level of peripheral amyloid-ß. Unexpectedly, and independent of amyloid pathology, the deletion of both apolipoproteins worsened behaviour deficits of double knockout mice and their performance was undistinguishable from those of Abca1 knockout mice. Finally we observed that the dendritic complexity in the CA1 region of hippocampus but not in CA2 is significantly impaired by Apoe/Apoa1 double deletion as well as by lack of ABCA1. IN CONCLUSION: (i) plasma lipoproteins may affect amyloid-ß clearance from the brain by the 'peripheral sink' mechanism; and (ii) deficiency of brain APOE-containing lipoproteins is of significance for dendritic complexity and cognition.

Genome-wide approaches reveal EGR1-controlled regulatory networks associated with neurodegeneration.

Early growth response gene 1 (Egr1) is a member of the immediate early gene (IEG) family of transcription factors and plays a role in memory formation. To identify EGR1 target genes in brain of Alzheimer's disease (AD) model mice - APP23, we applied chromatin immunoprecipitation (ChIP) followed by high-throughput DNA sequencing (ChIP-seq). Functional annotation of genes associated with EGR1 binding revealed a set of related networks including synaptic vesicle transport, clathrin-mediated endocytosis (CME), intracellular membrane fusion and transmission of signals elicited by Ca(2+) influx. EGR1 binding is associated with significant enrichment of activating chromatin marks and appears enriched near genes that are up-regulated in the brains of APP23 mice. Among the putative EGR1 targets identified and validated in this study are genes related to synaptic plasticity and transport of proteins, such as Arc, Grin1, Syn2, Vamp2 and Stx6, and genes implicated in AD such as Picalm, Psen2 and App. We also demonstrate a potential regulatory link between EGR1 and its newly identified targets in vivo, since conditions that up-regulate Egr1 levels in brain, such as a spatial memory test, also lead to increased expression of the targets. On the other hand, protein levels of EGR1 and ARC, SYN2, STX6 and PICALM are significantly lower in the brain of adult APP mice than in age-matched wild type animals. The results of this study suggest that EGR1 regulates the expression of genes involved in CME, vesicular transport and synaptic transmission that may be critical for AD pathogenesis.

Laboratory Test Names Matter: A Survey on What Works and What Doesn't Work for Orders and Results.

CONTEXT.­: Health care providers were surveyed to determine their ability to correctly decipher laboratory test names and their preferences for laboratory test names and result displays. OBJECTIVE.­: To confirm principles for laboratory test nomenclature and display and to compare and contrast the abilities and preferences of different provider groups for laboratory test names. DESIGN.­: Health care providers across different specialties and perspectives completed a survey of 38 questions, which included participant demographics, real-life examples of poorly named laboratory orders that they were asked to decipher, an assessment of vitamin D test name knowledge, their preferences for ideal names for tests, and their preferred display for test results. Participants were grouped and compared by profession, level of training, and the presence or absence of specialization in informatics and/or laboratory medicine. RESULTS.­: Participants struggled with poorly named tests, especially with less commonly ordered tests. Participants' knowledge of vitamin D analyte names was poor and consistent with prior published studies. The most commonly selected ideal names correlated positively with the percentage of the authors' previously developed naming rules (R = 0.54, P < .001). There was strong consensus across groups for the best result display. CONCLUSIONS.­: Poorly named laboratory tests are a significant source of provider confusion, and tests that are named according to the authors' naming rules as outlined in this article have the potential to improve test ordering and correct interpretation of results. Consensus among provider groups indicates that a single yet clear naming strategy for laboratory tests is achievable.

Avoiding Unintended Consequences of Pediatric Blood Order Set Updates through In Situ Usability Testing.

Background Blood product ordering is a complex process, and mistakes can lead to patient harm and poor outcomes. Orders and order sets can be designed to help mitigate errors, but major changes in design can unintentionally cause new errors. Objectives (1) Utilize formative in situ usability testing to iteratively improve the design of a redesigned blood product order set prior to go-live, (2) implement changes based on feedback derived from this testing, and (3) Compare the error rate, System Usability Scale (SUS) score, time to task completion, and click counts between the prior order set in use at the time and the revised redesigned order set. Methods A multidisciplinary project team convened to redesign blood product orders and order sets from scratch based on a review of literature and benchmarking against four pediatric academic institutions with the goal of addressing prior ordering errors. The new redesigned blood product order set was iteratively updated via in situ formative usability testing performed with available clinical users using a concurrent think-aloud protocol in real clinical environments. Errors, SUS scores, time to task completion, and click counts were assessed for the revised redesigned order set using summative testing. Results Formative usability testing with 20 participants led to seven design changes in the redesigned order set which reduced the error rate at go-live. Summative usability testing showed that even though the usability scores were only slightly improved for the revised redesigned order set, the error rates in blood orders were significantly decreased. Conclusion Usability testing can identify design errors early in the process which can be rectified prior to implementation, thus avoiding unintended consequences of changes.

Influence of user-centered clinical decision support on pediatric blood product ordering errors.

BACKGROUND: Children are at increased risk from transfusion-related medical errors. Clinical decision support (CDS) can enhance pediatric providers' decision-making regarding transfusion practices including indications, volume, rate, and special processing instructions. Our objective was to use CDS in a pediatric health system to reduce:blood product-related safety events from ordering errors;special processing ordering errors for patients with T-cell dysfunction, sickle cell disease (SCD), or thalassemia;transfusions administered faster than 5 mL/kg/h. MATERIALS AND METHODS: In this single-center before and after quality improvement study, we evaluated how user-centered design of pediatric blood product orders influenced pediatric transfusion practices and outcomes. Safety events were identified through active and passive surveillance. Other clinically relevant outcomes were identified through electronic health record queries. RESULTS: Blood product-related safety events from ordering errors did not change significantly from the baseline period (6 events, 0.4 per month, from 1/1/2018-3/27/2019) to the intervention period (1 event, 0.1 per month, from 3/28/2019-12/31/2019; rate ratio: 0.27 [0.01-2.25]). Packed red blood cell (PRBC) and platelet orders for patients with T-cell dysfunction that did not specify irradiation decreased significantly from 488/12,359 (3.9%) to 204/6,711 (3.0%, risk ratio: 0.77 [0.66-0.90]). PRBC orders for patients with SCD or thalassemia that did not specify phenotypically similar units fell from 386/2,876 (13.4%) to 57/1,755 (3.2%, risk ratio: 0.24 [0.18-0.32]). Transfusions administered faster than 5 mL/kg/h decreased from 4,112/14,641 (28.1%) to 2,125/9,263 (22.9%, risk ratio: 0.82 [0.78-0.85]). DISCUSSION: User-centered design of CDS for pediatric blood product orders significantly reduced special processing ordering errors and inappropriate transfusion rates. Larger studies are needed to evaluate the impact on safety events.

The expansion of data-related subjects in Pathology Informatics Essentials for Residents (PIER) and the Clinical Informatics fellowship examinations highlights the increasing significance of these skills in pathology practice in particular and medicine in general. The curriculum included lectures on databases, programming, analytics, machine learning basics, and specialized topics like anatomic pathology data analysis and dashboarding.

Interpersonal Connections Are Important for Virtual Kidney Transplant Educational Program Development.

Introduction: The Living Donor Navigator program is designed to mitigate disparities in living donor kidney transplantation, although geographic disparities in program participation were observed in the initial years of implementation. The purpose of this study was to understand participant perspectives regarding the use of a virtual option/alternative to expand program participation. Methods: Previous participants of the in-person navigator program were purposively sampled. Using the nominal group technique, a well-structured formative methodology to elicit participant perspectives, 2 meetings were conducted among transplant recipients and advocates (N = 13) to identify and prioritize responses to the question "What things would concern you about participating in a virtual and remote Living Donor Navigator program?" Findings: Mean participant age was 59.3 (9.3) years, and participants were 54% male and 62% white. Education levels varied from less than high school to master's degrees. Participants generated 70 unique responses, of which 36 (51.4%) received prioritization. The top 5 ranked responses of each nominal group technique meeting received approximately 50 percent (47.6% vs. 66.7%, respectively) of the total votes and described the potentially limited interpersonal connections, time conflicts, and differing content in a virtual navigator program compared to the in-person model. Discussion: These data suggest that previous participants were concerned with upholding the original design of the program, thus, virtual living donor kidney transplantation programs should aim to maintain interpersonal connections and consistency of content to ensure adequate programmatic engagement. Future research will focus on program fidelity independent of delivery modality.

Digital Pathology: Data-Intensive Frontier in Medical Imaging: Health-information sharing, specifically of digital pathology, is the subject of this paper which discusses how sharing the rich images in pathology can stretch the capabilities of all otherwise well-practiced disciplines.

Pathology is a medical subspecialty that practices the diagnosis of disease. Microscopic examination of tissue reveals information enabling the pathologist to render accurate diagnoses and to guide therapy. The basic process by which anatomic pathologists render diagnoses has remained relatively unchanged over the last century, yet advances in information technology now offer significant opportunities in image-based diagnostic and research applications. Pathology has lagged behind other healthcare practices such as radiology where digital adoption is widespread. As devices that generate whole slide images become more practical and affordable, practices will increasingly adopt this technology and eventually produce an explosion of data that will quickly eclipse the already vast quantities of radiology imaging data. These advances are accompanied by significant challenges for data management and storage, but they also introduce new opportunities to improve patient care by streamlining and standardizing diagnostic approaches and uncovering disease mechanisms. Computer-based image analysis is already available in commercial diagnostic systems, but further advances in image analysis algorithms are warranted in order to fully realize the benefits of digital pathology in medical discovery and patient care. In coming decades, pathology image analysis will extend beyond the streamlining of diagnostic workflows and minimizing interobserver variability and will begin to provide diagnostic assistance, identify therapeutic targets, and predict patient outcomes and therapeutic responses.

Electronic Health Records and Genomics: Perspectives from the Association for Molecular Pathology Electronic Health Record (EHR) Interoperability for Clinical Genomics Data Working Group.

The use of genomics in medicine is expanding rapidly, but information systems are lagging in their ability to support genomic workflows both from the laboratory and patient-facing provider perspective. The complexity of genomic data, the lack of needed data standards, and lack of genomic fluency and functionality as well as several other factors have contributed to the gaps between genomic data generation, interoperability, and utilization. These gaps are posing significant challenges to laboratory and pathology professionals, clinicians, and patients in the ability to generate, communicate, consume, and use genomic test results. The Association for Molecular Pathology Electronic Health Record Working Group was convened to assess the challenges and opportunities and to recommend solutions on ways to resolve current problems associated with the display and use of genomic data in electronic health records.

Greater community vulnerability is associated with poor living donor navigator program fidelity.

BACKGROUND: Community-level factors contribute to living donor kidney transplantation disparities but may also influence the interventions aimed to mitigate these disparities. The Living Donor Navigator Program was designed to separate the advocacy role from the patient in need of transplantation-friends/family are encouraged to participate as the patients' advocates to identify living donors, though some of the patients participate alone as self-advocates. Self-advocates have a lower living donor kidney transplantation likelihood compared to the patients with an advocate. We sought to evaluate the relationship between the patients' community-level vulnerability and living donor navigator self-advocacy as a surrogate for program fidelity. METHODS: This single-center, retrospective study included 110 Living Donor Navigator participants (April 2017-June 2019). Program fidelity was assessed using the participants' advocacy status. Measures of community vulnerability were obtained from the Centers for Disease Control and Prevention Social Vulnerability Index. Modified Poisson regression was used to evaluate the association between community-level vulnerability and living donor navigator self-advocacy. RESULTS: Of the 110 participants, 19% (n = 21) were self-advocates. For every 10% increase in community-level vulnerability, patients had 17% higher risk of self-advocacy (adjusted relative risk 1.17, 95% confidence interval: 1.03-1.32, P = .01). Living in areas with greater unemployment (adjusted relative risk: 1.18, 95% confidence interval: 1.04-1.33, P = .01), single-parent households (adjusted relative risk: 1.23, 95% confidence interval: 1.06-1.42, P = .006), minority population (adjusted relative risk: 1.30, 95% confidence interval: 1.04-1.55, P = .02), or no-vehicle households (adjusted relative risk: 1.17, 95% confidence interval: 1.02-1.35, P = .02) were associated with increased risk of self-advocacy. CONCLUSION: Having a greater community-level vulnerability was associated with poor Living Donor Navigator Program fidelity. The potential barriers identified using the Social Vulnerability Index may direct resource allocation and program refinement to optimize program fidelity and efficacy for all participants.

Lessons Learned from OpenNotes Learning Mode and Subsequent Implementation across a Pediatric Health System.

BACKGROUND: The 21st Century Cures Act has accelerated adoption of OpenNotes, providing new opportunities for patient and family engagement in their care. However, these regulations present new challenges, particularly for pediatric health systems aiming to improve information sharing while minimizing risks associated with adolescent confidentiality and safety. OBJECTIVE: Describe lessons learned preparing for OpenNotes across a pediatric health system during a 4-month trial period (referred to as "Learning Mode") in which clinical notes were not shared by default but decision support was present describing the upcoming change and physicians could request feedback on complex cases from a multidisciplinary team. METHODS: During Learning Mode (December 3, 2020-March 9, 2021), implementation included (1) educational text at the top of commonly used note types indicating that notes would soon be shared and providing guidance, (2) a new confidential note type, and (3) a mechanism for physicians to elicit feedback from a multidisciplinary OpenNotes working group for complex cases with questions related to OpenNotes. The working group reviewed lessons learned from this period, as well as implementation of OpenNotes from March 10, 2021 to June 30, 2021. RESULTS: During Learning Mode, 779 confidential notes were written across the system. The working group provided feedback on 14 complex cases and also reviewed 7 randomly selected confidential notes. The proportion of physician notes shared with patients increased from 1.3% to 88.4% after default sharing of notes to the patient portal. Key lessons learned included (1) sensitive information was often present in autopopulated elements, differential diagnoses, and supervising physician note attestations; and (2) incorrect reasons were often selected by clinicians for withholding notes but this accuracy improved with new designs. CONCLUSION: While OpenNotes provides an unprecedented opportunity to engage pediatric patients and their families, targeted education and electronic health record designs are needed to mitigate potential harms of inappropriate disclosures.

Comprehensive Genomic Profiling of High-Risk Pediatric Cancer Patients Has a Measurable Impact on Clinical Care.

PURPOSE: Profiling of pediatric cancers through deep sequencing of large gene panels and whole exomes is rapidly being adopted in many clinical settings. However, the most impactful approach to genomic profiling of pediatric cancers remains to be defined. METHODS: We conducted a prospective precision medicine trial, using whole-exome sequencing of tumor and germline tissue and whole-transcriptome sequencing (RNA Seq) of tumor tissue to characterize the mutational landscape of 127 tumors from 126 unique patients across the spectrum of pediatric brain tumors, hematologic malignancies, and extracranial solid tumors. RESULTS: We identified somatic tumor alterations in 121/127 (95.3%) tumor samples and identified cancer predisposition syndromes on the basis of known pathogenic or likely pathogenic germline mutations in cancer predisposition genes in 9/126 patients (7.1%). Additionally, we developed a novel scoring system for measuring the impact of tumor and germline sequencing, encompassing therapeutically relevant genomic alterations, cancer-related germline findings, recommendations for treatment, and refinement of risk stratification or prognosis. At least one impactful finding from the genomic results was identified in 108/127 (85%) samples sequenced. A recommendation to consider a targeted agent was provided for 82/126 (65.1%) patients. Twenty patients ultimately received therapy with a molecularly targeted agent, representing 24% of those who received a targeted agent recommendation and 16% of the total cohort. CONCLUSION: Paired tumor/normal whole-exome sequencing and tumor RNA Seq of de novo or relapsed/refractory tumors was feasible and clinically impactful in high-risk pediatric cancer patients.

Impact of Social Vulnerability on Access to Educational Programming Designed to Enhance Living Donation.

INTRODUCTION: Transplant candidate participation in the Living Donor Navigator Program is associated with an increased likelihood of achieving living donor kidney transplantation; yet not every transplant candidate participates in navigator programming. RESEARCH QUESTION: We sought to assess interest and ability to participate in the Living Donor Navigator Program by the degree of social vulnerability. DESIGN: Eighty-two adult kidney-only candidates initiating evaluation at our center provided Likert-scaled responses to survey questions on interest and ability to participate in the Living Donor Navigator Program. Surveys were linked at the participant-level to the Centers for Disease Control and Prevention Social Vulnerability Index and county health rankings and overall social vulnerability and subthemes, individual barriers, telehealth capabilities/ knowledge, interest, and ability to participate were assessed utilizing nonparametric Wilcoxon ranks sums tests, chi-square, and Fisher's exact tests. RESULTS: Participants indicating distance as a barrier to participation in navigator programming lived approximately 82 miles farther from our center. Disinterested participants lived in areas with the highest social vulnerability, higher physical inactivity rates, lower college education rates, and higher uninsurance (lack of insurance) and unemployment rates. Similarly, participants without a computer, who never heard of telehealth, and who were not encouraged to participate in telehealth resided in areas of highest social vulnerability. CONCLUSION: These data suggest geography combined with being from under-resourced areas with high social vulnerability was negatively associated with health care engagement. Geography and poverty may be surrogates for lower health literacy and fewer health care interactions.

Evaluation of Community-Level Vulnerability and Racial Disparities in Living Donor Kidney Transplant.

Importance: Living donor kidney transplant (LDKT) is the ideal treatment for end-stage kidney disease, but racial disparities in LDKT have increased over the last 2 decades. Recipient clinical and social factors do not account for LDKT racial inequities, although comprehensive measures of community-level vulnerability have not been assessed. Objective: To determine if racial disparities persist in LDKT independent of community-level vulnerability. Design, Setting, and Participants: This retrospective, multicenter, cross-sectional study included data from 19 287 adult kidney-only transplant recipients in the Scientific Registry of Transplant Recipients. The study included individuals who underwent transplant between January 1 and December 31, 2018. Exposures: Recipient race and the 2018 US Centers for Disease Control and Prevention Social Vulnerability Index (SVI). Census tract-level SVI data were linked to census tracts within each recipient zip code. The median SVI measure among the census tracts within a zip code was used to describe community-level vulnerability. Main Outcomes and Measures: Kidney transplant donor type (deceased vs living). Modified Poisson regression was used to evaluate the association between SVI and LDKT, and to estimate LDKT likelihood among races, independent of community-level vulnerability and recipient-level characteristics. Results: Among 19 287 kidney transplant recipients, 6080 (32%) received LDKT. A total of 11 582 (60%) were male, and the median (interquartile range) age was 54 (43-63) years. There were 760 Black LDKT recipients (13%), 4865 White LDKT recipients (80%), and 455 LDKT recipients of other races (7%; American Indian, Asian, multiracial, and Pacific Islander). Recipients who lived in communities with higher SVI (ie, more vulnerable) had lower likelihood of LDKT compared with recipients who lived in communities with lower SVI (ie, less vulnerable) (adjusted relative risk [aRR], 0.97; 95% CI, 0.96-0.98; P < .001). Independent of community-level vulnerability, compared with White recipients, Black recipients had 37% lower likelihood (aRR, 0.63; 95% CI, 0.59-0.67; P < .001) and recipients of other races had 24% lower likelihood (aRR, 0.76; 95% CI, 0.70-0.82; P < .001) of LDKT. The interaction between SVI and race was significant among Black recipients, such that the disparity in LDKT between Black and White recipients increased with greater community-level vulnerability (ratio of aRRs, 0.67; 95% CI, 0.51-0.87; P = .003). Conclusions and Relevance: Community-level vulnerability is associated with access to LDKT but only partially explains LDKT racial disparities. The adverse effects of living in more vulnerable communities were worse for Black recipients. The interaction of these constructs is worrisome and suggests evaluation of other health system factors that may contribute to LDKT racial disparities is needed.

Self-advocacy is associated with lower likelihood of living donor kidney transplantation.

BACKGROUND: The Living Donor Navigator (LDN) Program pairs kidney transplant candidates (TC) with a friend or family member for advocacy training to help identify donors and achieve living donor kidney transplantation (LDKT). However, some TCs participate alone as self-advocates. METHODS: In this retrospective cohort study of TCs in the LDN program (04/2017-06/2019), we evaluated the likelihood of LDKT using Cox proportional hazards regression and rate of donor screenings using ordered events conditional models by advocate type. RESULTS: Self-advocates (25/127) had lower likelihood of LDKT compared to patients with an advocate (adjusted hazard ratio (aHR): 0.22, 95% confidence interval (CI): 0.03-1.66, p = 0.14). After LDN enrollment, rate of donor screenings increased 2.5-fold for self-advocates (aHR: 2.48, 95%CI: 1.26-4.90, p = 0.009) and 3.4-fold for TCs with an advocate (aHR: 3.39, 95%CI: 2.20-5.24, p < 0.0001). CONCLUSIONS: Advocacy training was beneficial for self-advocates, but having an independent advocate may increase the likelihood of LDKT.

Patient misidentifications caused by errors in standard bar code technology.

BACKGROUND: Bar code technology has decreased transcription errors in many healthcare applications. However, we have found that linear bar code identification methods are not failsafe. In this study, we sought to identify the sources of bar code decoding errors that generated incorrect patient identifiers when bar codes were scanned for point-of-care glucose testing and to develop solutions to prevent their occurrence. METHODS: We identified misread wristband bar codes, removed them from service, and rescanned them by using 5 different scanner models. Bar codes were reprinted in pristine condition for use as controls. We determined error rates for each bar code-scanner pair and manually calculated internal bar code data integrity checks. RESULTS: As many as 3 incorrect patient identifiers were generated from a single bar code. Minor bar code imperfections, failure to control for bar code scanner resolution requirements, and less than optimal printed bar code orientation were confirmed as sources of these errors. Of the scanner models tested, the Roche ACCU-CHEK® glucometer had the highest error rate. The internal data integrity check system did not detect these errors. CONCLUSIONS: Bar code-related patient misidentifications can occur. In the worst case, misidentified patient results could have been transmitted to the incorrect patient medical record. This report has profound implications not only for point-of-care testing but also for bar coded medication administration, transfusion recipient certification systems, and other areas where patient misidentifications can be life-threatening. Careful control of bar code scanning and printing equipment specifications will minimize this threat to patient safety. Ultimately, healthcare device manufacturers should adopt more robust and higher fidelity alternatives to linear bar code symbologies.

Telepathology for patient care: what am I getting myself into?

The vast advancements in telecommunications and converting medical information to a digital format have increased the number of applications within telemedicine. Telepathology, in simplest terms, is the practice of formally rendering a pathologic diagnosis based upon examination of an image rather than of a glass slide through traditional microscopy. The use of telepathology for clinical patient care has so far been limited to relatively few large academic institutions. Although a number of challenges remain, there is increasing demand for the use of information technology in pathology as a whole owing to the expansion of health care networks and the opportunity to enhance the quality of service delivered to patients. The software used to acquire, display, and manage digital images for clinical patient care may be subject to national and federal regulations just as is any other electronic information system. Despite the barriers, telepathology systems possess the capability to help manage pathology cases on a global scale, improve laboratory workload distribution, increase standardization of practice and enable new classes of ancillary studies to facilitate diagnosis and education even in the most remote parts of the earth.
