ABSTRACT

BACKGROUND: With the widespread adoption of Blood Establishment Computer Systems and other Blood Collection and Transfusion Service (BCTS) clinical information systems (CIS), electronic blood donor, product, and patient data are now routinely required for clinical, regulatory, operational, and quality needs. That data are often not readily accessible for such secondary use within CIS databases, particularly for applications with significant data availability requirements such as machine learning and artificial intelligence. Data replication provides one avenue by which CIS data can be made more readily available. STUDY DESIGN AND METHODS: Members of the AABB's Information Systems Committee along with institutional information technology colleagues provided a multi-institutional viewpoint on data replication through the lens of BCTS specific use cases. Case studies of informatics offerings leveraging such technologies were also elicited. RESULTS: Six distinct use cases describe the potential role of data replication including the creation of data warehouses for frontline laboratory staff. Specific BCTS examples for each use case are presented to highlight the value of data replication, including visualization of critical inventory (O red blood cells, HLA-compatible platelets) and utilization analytics for patient blood management. Two case studies describe the approach to implement such technologies to (1) optimize staffing via laboratory workload reporting and (2) improve access to blood via antigen-negative blood product location services. DISCUSSION: Data replication and warehousing can empower BCTS analytic offerings not otherwise natively available through one's CIS to improve patient care and laboratory operations.

ABSTRACT

A 62-year-old woman with acute myeloid leukemia (AML) died of shock and massive hemolysis shortly after receiving two platelet transfusions at a routine clinic visit. Subsequent investigation into what was initially believed to be an acute hemolytic transfusion reaction secondary to platelet transfusions revealed that the patient died of Clostridium perfringens sepsis leading to massive hemolysis. Further investigation ruled out bacterially-contaminated platelets since a patient blood sample from 2 days prior had Clostridium species. The unusual findings and management considerations for this oncology patient are reviewed and compared with previously reported cases of C. perfringens transfusion-transmitted infections. Oncology patients may be especially susceptible to unusual presentations involving unusual pathogens.

ABSTRACT

Next-generation sequencing (NGS) is rapidly expanding into routine oncology practice. Genetic variations in both the cancer and inherited genomes are informative for hereditary cancer risk, prognosis, and treatment strategies. Herein, we focus on the clinical perspective of integrating NGS results into patient care to assist with therapeutic decision making. Five key considerations are addressed for operationalization of NGS testing and application of results to patient care as follows: (1) NGS test ordering and workflow design; (2) result reporting, curation, and storage; (3) clinical consultation services that provide test interpretations and identify opportunities for molecularly guided therapy; (4) presentation of genetic information within the electronic health record; and (5) education of providers and patients. Several of these key considerations center on informatics tools that support NGS test ordering and referencing back to the results for therapeutic purposes. Clinical decision support tools embedded within the electronic health record can assist with NGS test utilization and identifying opportunities for targeted therapy including clinical trial eligibility. Challenges for project and change management in operationalizing NGS-supported, evidence-based patient care in the context of current information technology systems with appropriate clinical data standards are discussed, and solutions for overcoming barriers are provided.

ABSTRACT

Clinical practice is most efficient when physicians have the right information, including pathology and laboratory results, at the point of contact with the patient. In downstream workflows, subsequent groups using lab data want to have it available in a format that is easy to manipulate. With the complexity of electronic medical records, hospital information systems, and the need to accommodate data from outside systems, this is not easy to accomplish. By utilizing a group of concepts from clinical and pathology informatics, system implementations may be improved to achieve relevant laboratory data in a format that is usable by healthcare entities to improve patient care and forward endeavors in precision medicine.

ABSTRACT

PURPOSE: Hematopoietic Progenitor Cell (HPC) collection by apheresis is performed in patients and donors to obtain HPCs for transplantation. Although studies have shown these procedures to be safe, successful collection cannot be performed without establishment of venous access. This project's objective was to ascertain the current practices of donor vein assessment and central venous catheter (CVC) usage. METHODS: The American Society for Apheresis (ASFA) HPC subcommittee created an electronic survey about precollection vein assessment and line placement, care, and removal in autologous and allogeneic donors. It was distributed to >5,000 possible participants, with one response analyzed per institution. RESULTS: One hundred centers performing autologous and/or allogeneic procedures provided adequate responses for analysis. Donor vein assessment is most often performed by apheresis staff more than 1 week prior to collection. For patients with questionable access, the next step performed most often is secondary assessment for autologous procedures and CVC placement for allogeneic procedures. Most centers use interventional radiology to place CVCs in jugular veins on collection day with placement verification through electronic medical records. Verbal and written postinsertion CVC care instructions are routinely provided. The apheresis team frequently provides postinsertion CVC care for autologous patients. Heparin is used most often for CVC lock. When used, tissue plasminogen activator is usually instilled for up to 60 min. CONCLUSION: These data summarize the largest single survey of donor vein assessment at institutions performing HPC collections by apheresis. The variations identified in donor venous access practice warrant further investigation and consensus to establish best practices. J. Clin.

ABSTRACT

BACKGROUND: In subsets of pediatric cardiac surgery patients, red blood cells (RBCs) are often washed to reduce extracellular potassium (K) to avoid hyperkalemia, but mechanical manipulation and time delay in issuing washed products may increase hemolysis and K. This study's purpose was to evaluate the quality of washed RBCs with regard to hemolysis and extracellular K using different cell washers as a function of postprocessing time. STUDY DESIGN AND METHODS: Fresh (<4 days old) RBCs were washed on COBE 2991 blood cell processors (Model 1 and Model 2) or the Fresenius Continuous AutoTransfusion System (CATS), and K and hemolysis index (HI) were analyzed. Academic pediatric hospitals were surveyed to ascertain practice trends regarding indications for washing, washing device, and expiration time for washed RBCs. RESULTS: K concentration at 24 hours for units washed with the COBE devices met or exceeded prewash values. At 12 hours, there was a significant difference (p < 0.001) in K concentration between all devices, with the CATS maintaining the lowest K concentration. HI increased immediately after wash on all devices and showed a significant difference between the COBE devices and CATS at times of more than 6 hours (p < 0.01). At storage times beyond 4 hours, hemoglobin exceeded 100 mg/dL on the COBE Model 1. Survey of pediatric hospitals indicated that COBE devices are commonly used, and storage time after washing was 12 hours or more in blood banks queried. CONCLUSIONS: Hemolysis levels vary among different cell washers. Decreasing the expiration time of units after washing may be warranted.

ABSTRACT

We describe a 2009 H1N1 virus infection with a high viral load in a previously healthy infant who presented with complex febrile seizures and improved on oseltamivir without neurologic sequelae. Febrile seizures may be a complication in young children experiencing infection with high viral loads of 2009 H1N1 influenza virus.

ABSTRACT

BACKGROUND: Current practices of reporting critical laboratory values make it challenging to measure and assess the timeliness of receipt by the treating physician as required by The Joint Commission's 2008 National Patient Safety Goals. METHODS: A multidisciplinary team of laboratorians, clinicians, and information technology experts developed an electronic ALERTS system that reports critical values via the laboratory and hospital information systems to alphanumeric pagers of clinicians and ensures failsafe notification, instant documentation, automatic tracking, escalation, and reporting of critical value alerts. A method for automated acknowledgment of message receipt was incorporated into the system design. RESULTS: The ALERTS system has been applied to inpatients and eliminated approximately 9000 phone calls a year made by medical technologists. Although a small number of phone calls were still made as a result of pages not acknowledged by clinicians within 10 min, they were made by telephone operators, who either contacted the same physician who was initially paged by the automated system or identified and contacted alternate physicians or the patient's nurse. Overall, documentation of physician acknowledgment of receipt in the electronic medical record increased to 95% of critical values over 9 months, while the median time decreased to <3 min. CONCLUSIONS: We improved laboratory efficiency and physician communication by developing an electronic system for reporting of critical values that is in compliance with The Joint Commission's goals.

ABSTRACT

Extraadrenal pheochromocytomas and paragangliomas are rare entities within the pediatric population. We report the presentation of three synchronous extra-adrenal abdominal paragangliomas in an adolescent boy who carries a germline mutation in the succinate dehydrogenase B (SDHB) gene. Loss of heterozygosity of this allele was demonstrated by direct sequencing of DNA from two of his tumors, confirming loss of tumor suppressor function in the pathogenesis of these paragangliomas.

ABSTRACT

Cutaneous focal mucinosis has been rarely reported in association with follicular induction of the epidermis. We present 2 cases of focal mucinosis with follicular induction and describe the histopathologic findings to create awareness of this association and to prevent confusion with other diagnoses such as dermatofibroma with follicular induction or superficial basal cell carcinoma.
