Evaluation of the quality of mammographic breast positioning: a quality improvement study.

BACKGROUND: Although there are concerns that inadequate breast positioning in mammographic examinations may lead to cancers being missed, few studies have examined the quality of breast positioning, especially in the Canadian context. Our objective was to assess the quality of breast positioning in mammographic examinations in a Quebec-wide representative sample of technologists. METHODS: This quality improvement study was part of a professional inspection launched by the Ordre des technologues en imagerie médicale, en radio-oncologie et en électrophysiologie médicale du Québec among its members. The inspection was conducted between May and July 2017 on a proportionate stratified random sample of all active technologists certified in mammography in Quebec. Each technologist provided images from 15 consecutive mammographic examinations they performed in the previous 6 months. The quality of positioning was then evaluated by senior technologists using a quality assessment tool specifically developed for this inspection. A technologist was deemed to have failed the professional inspection when at least 7 of the 15 mammographic examinations were scored as critical failures. Proportions were calculated accounting for sampling weights and correction for finite population. RESULTS: Among the 520 technologists certified in mammography in Quebec, 76 technologists (14.6%) were randomly selected for the professional inspection and contributed images from 1127 mammographic examinations. Thirty-eight technologists (weighted percentage 50.3%, 95% confidence interval [CI] 37.6% to 63.0%) failed the professional inspection. Overall, 492 mammographic examinations (43.7%, 95% CI 38.6% to 48.8%) had at least 1 image scored as a critical failure. INTERPRETATION: Half of the technologists performing mammographic examinations in Quebec who participated in this study failed the inspection, and a substantial proportion of their mammographic examinations demonstrated critical failures in breast positioning. Overall, our findings are concordant with those of previous studies and highlight the need for additional investigations assessing the quality of breast positioning in mammographic examinations in other jurisdictions.

Strategies to ensure efficient laboratory functioning while navigating through the COVID-19 crisis in developing countries: An early experience from a tertiary care centre in India.

BACKGROUND: The coronavirus disease 2019 (COVID 19) is a zoonotic viral infection that originated in Wuhan, China, in December 2019. It was declared a pandemic by the World Health Organization shortly thereafter. This pandemic is going to have a lasting impact on the functioning of pathology laboratories due to the frequent handling of potentially infectious samples by the laboratory personnel. To deal with this unprecedented situation, various national and international guidelines have been put forward outlining the precautions to be taken during sample processing from a potentially infectious patient. PURPOSE: Most of these guidelines are centered around laboratories that are a part of designated COVID 19 hospitals. However, proper protocols need to be in place in all laboratories, irrespective of whether they are a part of COVID 19 hospital or not as this would greatly reduce the risk of exposure of laboratory/hospital personnel. As part of a laboratory associated with a rural cancer hospital which is not a dedicated COVID 19 hospital, we aim to present our institute's experience in handling pathology specimens during the COVID 19 era. CONCLUSION: We hope this will address the concerns of small to medium sized laboratories and help them build an effective strategy required for protecting the laboratory personnel from risk of exposure and also ensure smooth and optimum functioning of the laboratory services.

Audit in surgical histopathology at a tertiary healthcare center: Study of preanalytical and analytical phase.

CONTEXT: An audit aims to verify conformance to required processes, assess their implementation, and define the targets of quality control. AIMS: To evaluate preanalytic and analytic phases of surgical histopathology in a tertiary healthcare center. SETTING AND DESIGN: An observational retrospective and prospective study over 3 months each of year 2013 and 2014. MATERIALS AND METHODS: Biopsy, small resections, large organ resections, bone marrow aspirate/biopsy (BMA/BMB), and frozen section samples received in surgical histopathology were categorized as I to V, respectively. A manual audit was done for preanalytical phase (adequacy of clinical information and grossing adequacy) and analytical phase [turnaround time (TAT) and tissue section quality]. STATISTICAL ANALYSIS: Qualitative data was assessed by Chi-Square test. Quantitative data was assessed using One-Way Analysis of Variance. RESULTS: Among 3179 total cases, category I to V had 1558 (49%), 1099 (34.6%), 342 (10.8%), 124 (3.8%), and 56 (1.8%) cases, respectively. Category I had shortest TAT but maximum number of inadequately sent specimens and recuts. Category III had maximum cases with inadequate clinical history, grossing errors, additional sections, and longest TAT. Category IV had maximum cases with poor quality sections. Category V had maximum cases with inadequate demographic details and clinical investigations. BMB (114, 91.9%) was more useful than BMA for diagnosis. Mean TAT for fixed tissues and frozen tissues was 3.6 ± 1.8 days and 26.6 ± 11.2 min, respectively. CONCLUSIONS: Total 25% of annual workload was studied by an observational, manual audit. Quality indicators were achieved as per international norms despite limited resources. Remedial actions were suggested for technicians, clinicians, and pathologists to minimize errors.

Challenges and Controversies to Testing for COVID-19.

The coronavirus disease (COVID-19) pandemic has placed the clinical laboratory and testing for SARS-CoV-2 front and center in the worldwide discussion of how to end the outbreak. Clinical laboratories have responded by developing, validating, and implementing a variety of molecular and serologic assays to test for SARS-CoV-2 infection. This has played an essential role in identifying cases, informing isolation decisions, and helping to curb the spread of disease. However, as the demand for COVID-19 testing has increased, laboratory professionals have faced a growing list of challenges, uncertainties, and, in some situations, controversy, as they have attempted to balance the need for increasing test capacity with maintaining a high-quality laboratory operation. The emergence of this new viral pathogen has raised unique diagnostic questions for which there have not always been straightforward answers. In this commentary, the author addresses several areas of current debate, including (i) the role of molecular assays in defining the duration of isolation/quarantine, (ii) whether the PCR cycle threshold value should be included on patient reports, (iii) if specimen pooling and testing by research staff represent acceptable solutions to expand screening, and (iv) whether testing a large percentage of the population is feasible and represents a viable strategy to end the pandemic.

Laboratory Staff Turnover: A College of American Pathologists Q-Probes Study of 23 Clinical Laboratories.

CONTEXT.­: Knowledge of laboratory staff turnover rates are important to laboratory medical directors and hospital administrators who are responsible for ensuring adequate staffing of their clinical laboratories. The current turnover rates for laboratory employees are unknown. OBJECTIVE.­: To determine the 3-year average employee turnover rates for clinical laboratory staff and to survey the types of institutional human resource practices that may be associated with lower turnover rates. DESIGN.­: We collected data from participating laboratories spanning a 3-year period of 2015-2017, which included the number of full-time equivalent (FTE) staff members that their laboratories employed in several personnel and departmental categories, and the number of laboratory staff FTEs who vacated each of those categories that institutions intended to refill. We calculated the 3-year average turnover rates for all laboratory employees, for several personnel categories, and for major laboratory departmental categories, and assessed the potential associations between 3-year average all laboratory staff turnover rates with institutional human resource practices. RESULTS.­: A total of 23 (20 US and 3 international) participating institutions were included in the analysis. Among the 21 participants providing adequate turnover data, the median of the 3-year average turnover rate for all laboratory staff was 16.2%. Among personnel categories, ancillary staff had the lowest median (11.1% among 21 institutions) and phlebotomist staff had the highest median (24.9% among 20 institutions) of the 3-year average turnover rates. Among laboratory departments, microbiology had the lowest median (7.8% among 18 institutions) and anatomic pathology had the highest median (14.3% among 14 institutions) of the 3-year average turnover rates. Laboratories that developed and communicated clear career paths to their employees and that funded external laboratory continuing education activities had significantly lower 3-year average turnover rates than laboratories that did not implement these strategies. CONCLUSIONS.­: Laboratory staff turnover rates among institutions varied widely. Two human resource practices were associated with lower laboratory staff turnover rates.

Study of the Pre-Analytical Phase of an ISO 15189: 2012-Certified Cytopathology Laboratory: A 5-Year Institutional Experience.

OBJECTIVE: Total quality management, which basically involves pre-analytical, analytical, and postanalytical phases, is relatively more difficult in cytopathology due to descriptive reports and subjective variability. The pre-analytical phase of total quality management constitutes a major burden of errors in the laboratory and it has not been widely studied in cytopathology except in cervical Pap smears. The present study was therefore conducted to study the pre-analytical phase over 5 years from April 2013 until May 2018 at an ISO 15189: 2012-certified cytopathology laboratory, in a resource-limited setting. It was also intended to study the level of satisfaction of the patients and the training of the professionals provided in the cytology lab so as to improve and maintain high quality standards. METHODS: The study included all the documents relating to the quality program used in the last 5 years in a medical institute situated in the north sub-Himalayan region of India. All the data were recorded and analysed for pre-analytical analysis of the total quality management system. RESULTS: In total, 20,130 samples were received for cytological investigation. The total number of errors which were detected in the cytopathology lab were 1,430, constituting 7.1% of the total investigations done. The pre-analytical phase errors comprised 57% of the total errors (815/1,430), analytical errors constituted 11% (157/1,430), while postanalytical errors represented 32% (458/1,430). Incompletely filled requisition forms constituted the most common pre-analytical error (38%). There was a gradual decrease in the errors with time, but with a sudden increase between January to June 2015 due to new technicians joining during that period. CONCLUSION: Pre-analytical quality management is an essential component for maintaining the quality and reducing the errors in the cytopathology lab. Documentation, continuous training, and maintenance of internal and external quality control with quality charts are the key for successful quality management. The identification of non-conformance with root-cause analysis and provision of scope for continuous improvement is vital for quality improvement in the lab. Patient satisfaction is an important aspect of quality in the lab, which should be combined with the satisfaction of the personnel working in the lab.

Improvement of blood culture contamination rate, blood volume, and true positive rate after introducing a dedicated phlebotomy team.

The introduction of dedicated phlebotomy teams certified for blood collection has been reported to be highly cost-effective by reducing contamination rates. However, data on their effects on blood volume and true positive rate are limited. Therefore, we investigated the effect of replacing interns with a phlebotomy team on blood culture results. We performed a 24-month retrospective, quasi-experimental study before and after the introduction of a phlebotomy team dedicated to collecting blood cultures in a 2700-bed tertiary-care hospital. The microbiology laboratory database was used to identify adult patients with positive blood culture results. During the study period, there were no changes in blood collection method, blood culture tubes, and the application of antiseptic measures. Blood volume was measured by the BACTEC™ FX system based on red blood cell metabolism. A total of 162,207 blood cultures from 23,563 patients were analyzed, comprising 78,673 blood cultures during the intern period and 83,534 during the phlebotomy team period. Blood volume increased from a mean of 2.1 ml in the intern period to a mean of 5.6 ml in the phlebotomy team period (p < 0.001). Introduction of the phlebotomy team also reduced contamination rate (0.27% vs. 0.45%, p < 0.001) and led to a higher true positive rate (5.87% vs. 5.01%, p < 0.05). The increased true positive rate associated with the phlebotomy team involved both gram-positive and gram-negative bacteria. The introduction of a dedicated phlebotomy team can increase blood volumes, reduce blood culture contamination rate, and increase true positive rate.

Improving bone marrow biopsy quality through peer discussion and data comparisons: A single institution experience.

INTRODUCTION: Bone marrow biopsy (BMB) is crucial for the diagnosis, staging, and monitoring of a variety of hematologic diseases. Obtaining an adequate BMB can be challenging given the need to balance patient comfort with acquisition of high quality specimens. We had observed variable BMB quality at our institution with poor quality specimens sometimes affecting diagnosis. We thus undertook this quality improvement (QI) project to improve the quality of diagnostic BMB specimens. METHODS: We used an A3 QI process to identify factors possibly influencing BMB quality. We collected baseline data on 211 BMB, with short and long-term follow-up data on a further 382 cases. We used clinical conferences to discuss data, perform peer comparisons and identify strategies to create a sustainable improvement in BMB quality. RESULTS: Baseline data showed that BMB length was influenced most by the individual performer, with some influence of needle gauge. Other factors such as sedation, BMB indication were noncontributory. BMB lengths improved following performer education and individual performer data comparisons (15.2 mm post vs 12.8 mm baseline, P < .0001) and with use of an 8- rather than 11-gauge needle (18.3 mm 8-gauge vs 13.3 mm 11-gauge P < .0001), and were sustained over the long term. CONCLUSIONS: Education on BMB standards, sharing of performer data, and changing needle gauge are relatively straightforward methods to improve BMB quality, leading to easier pathology diagnosis.

European registration process for Clinical Laboratory Geneticists in genetic healthcare.

Tremendous progress in genetics and genomics led to a wide range of healthcare providers, genetic tests, and more patients who can benefit from these developments. To guarantee and improve the quality of genetic testing, a unified European-based registration for individuals qualified in biomedicine was realized. Therefore a Europe-wide recognition of the profession 'European registered Clinical Laboratory Geneticist (ErCLG)' based on a syllabus of core competences was established which allows for harmonization in professional education. The 'European Board of Medical Genetics division - Clinical Laboratory Geneticist' provides now since 3 years the possibility to register as an ErCLG. Applicants may be from all European countries and since this year also from outside of Europe. Five subtitles reflect the exact specialty of each ErCLG, who can reregister every 5 years. A previously not possible statistics based on ~300 individuals from 19 countries as holders of an ErCLG title provides interesting insights into the professionals working in human genetics. It could be substantiated that there are around twice as many females than males and that a PhD title was achieved by 80% of registered ErCLGs. Also most ErCLGs are still trained as generalists (66%), followed by such ErCLGs with focus on molecular genetics (23%); the remaining are concentrated either on clinical (6%), tumor (4%) or biochemical genetics (1%). In conclusion, besides MDs and genetic counselors/nurses an EU-wide recognition system for Clinical Laboratory Geneticist has been established, which strengthens the status of specialists working in human genetic diagnostics in Europe and worldwide.

Agreement between cytotechnologists and cytopathologists as a new measure of cytopathologist performance in gynecologic cytology.

BACKGROUND: Although objective measures of cytotechnologist (CT) and cytopathologist (CP) performance exist, challenges remain. Two assumptions deserve examination: CPs' interpretations are correct, and CTs and CPs render interpretations independently of each other. This study presents a CT-CP interpretation comparison and provides insight into these assumptions. METHODS: Every gynecologic cytology specimen examined by both a CT and a CP from December 2004 to March 2015 was extracted from the laboratory information system; glandular interpretations were excluded. Excel and SAS were used for CT-CP pair analysis. CT-CP pairs with fewer than 32 specimens (the lowest quartile) were excluded. For the remaining CT-CP pairs, 30 specimens or 10% of the specimens (whichever was higher) were randomly selected for comparison by a weighted κ statistic. κ values greater than 0.6 represented good agreement within CT-CP pairs. RESULTS: This study evaluated 7116 of 53,241 gynecologic cytology specimens (13.4%) that received CT and CP interpretations. This resulted in 155 pair-specific κ values from 15 CTs and 16 CPs. In aggregate, the κ values had a mean of 0.64, a standard deviation of 0.14, a median of 0.65, and a range of 0.27 to 0.91. Nine CTs exhibited good agreement in the majority of their pair-specific κ values with CPs (high-concordance CTs; 88 pair-specific κ values). This allowed us to identify outlier CPs who did not demonstrate good agreement with high-concordance CTs (16 of 88 pair-specific κ values [18.2%]). CONCLUSIONS: Laboratories can use this κ to determine when CP levels of agreement with CTs depart from those of their peers. Adding this to established metrics can give a more nuanced impression of CP performance. Cancer Cytopathol 2017;125:576-80. © 2017 American Cancer Society.

Proceedings of the African Pathologists Summit; March 22-23, 2013; Dakar, Senegal: a summary.

CONTEXT: This report presents the proceedings of the African Pathologists Summit, held under the auspices of the African Organization for Research and Training in Cancer. OBJECTIVES: To deliberate on the challenges and constraints of the practice of pathology in Sub-Saharan Africa and the avenues for addressing them. PARTICIPANTS: Collaborating organizations included the American Society for Clinical Pathology; Association of Pathologists of Nigeria; British Division of the International Academy of Pathology; College of Pathologists of East, Central and Southern Africa; East African Division of the International Academy of Pathology; Friends of Africa-United States and Canadian Academy of Pathology Initiative; International Academy of Pathology; International Network for Cancer Treatment and Research; National Cancer Institute; National Health and Laboratory Service of South Africa; Nigerian Postgraduate Medical College; Royal College of Pathologists; West African Division of the International Academy of Pathology; and Faculty of Laboratory Medicine of the West African College of Physicians. EVIDENCE: Information on the status of the practice of pathology was based on the experience of the participants, who are current or past practitioners of pathology or are involved in pathology education and research in Sub-Saharan Africa. CONSENSUS PROCESS: The deliberations were carried out through presentations and working discussion groups. CONCLUSIONS: The significant lack of professional and technical personnel, inadequate infrastructure, limited training opportunities, poor funding of pathology services in Sub-Saharan Africa, and their significant impact on patient care were noted. The urgency of addressing these issues was recognized, and the recommendations that were made are contained in this report.

Training and practice of cytotechnologists: a discussion forum focused on Europe.

OBJECTIVES: To discuss the role and training of cytotechnologists (CTs) in Europe, to identify areas of good practice and to provide an informed opinion to those providing guidelines for training and practice in Europe. METHODS: All members of the Editorial Advisory Board of Cytopathology were invited to take part in a 'discussion forum' for which six topics were circulated in advance concerning the roles of CTs with regard to: (1) pre-screening slides; (2) 'signing out' reports; (3) carrying out ancillary techniques; (4) supervising laboratory staff; (5) taking part in rapid on-site evaluation (ROSE) of fine needle aspirates (FNAs); and (6) whether CTs were trained specifically in cytopathology or in general histopathology. Notes of the meeting were circulated by email and a final report was agreed by 22 participants from 17 predominantly European countries. RESULTS: Training for CTs throughout Europe was variable, especially for non-gynaecological cytology, which was inconsistent with the range of activities required. The participants recommended graduate entry, preliminary training in general laboratory technology, and subsequent training to take account of the probability and, in some centres, the reality of primary cervical cancer screening changing from cytology to human papillomavirus (HPV) testing. They further recommended that CTs should perform HPV tests and take part in ROSE for FNAs, and they supported the European Federation of Cytology Societies developing guidelines for training and practice. CONCLUSION: With CT training added to a university-based education in laboratory or biomedical science, a career in cytotechnology should be an attractive option involving a diverse range of laboratory and clinically based activities.

Accuracy of cytotechnologist evaluation of specimen adequacy and screening interpretation of malignancy in fine-needle aspiration of the liver.

OBJECTIVE: To evaluate the performance of cytotechnologists in assessing the adequacy and accuracy of the preliminary diagnosis for fine-needle aspirates of the liver. STUDY DESIGN: We retrospectively analyzed 10 years of data and found 589 cases of ultrasound-guided fine-needle aspiration (FNA) of the liver with on-site evaluation of adequacy (OSEA). All the OSEA were performed by the cytopathologist because OSEA of liver FNA is not performed by cytotechnologists at our institution at present. After OSEA, the material was seen by cytotechnologists who rendered an adequacy assessment and preliminary diagnosis. We calculated the adequacy and accuracy statistics and compared the performance of the cytotechnologists with the OSEA and final interpretation. RESULTS: There was no statistically significant difference in adequacy downgrade rate for cytotechnologist versus cytopathologist assessment during the study period (5 vs. 3%, p = 0.06). A total agreement of 88% was noted in overall diagnosis with 97% agreement in malignant cases. CONCLUSION: Cytotechnologists assess the adequacy of liver FNA accurately and there is therefore potential for them to perform OSEA for liver FNA.

Survey of training and education of cytotechnologists in Europe.

OBJECTIVE: This report presents the results of a survey of the training and education of cytotechnologists (CTs) in 15 European countries and suggests guidelines on which future education should be developed. METHODS: A questionnaire was sent to 25 countries in 2011: 14 with and 11 without a European Advisory Committee of Cytotechnology (EACC) member or representative. We received responses from 18 countries, among which three were excluded from the survey because they did not have CTs in training. RESULTS: The number of fully trained and employed CTs in these 15 European countries varied from 35 to 2600. The level of responsibility for most CTs in 14 of these countries was intermediate (signing out negative and inadequate gynaecological samples), whereas seven also had a minority of CTs at an advanced level (signing out abnormal gynaecological samples). Basic education was equally divided (7/8) between countries requiring a bachelor degree or training in medical technology before entry into cytology training. The training in cytology was given as a separate course/education or a combination of separate courses and in-house training, but was often confined to gynaecological cytology. It was recognized that CTs should extend their activities with the advent of human papillomavirus (HPV) testing and vaccination. The training requirement for CTs was usually decided by the national professional society. Most cytology training programmes were accredited by academic institutions at university level and were recognized nationally in almost all of the countries. For most of the countries, the optimal education in the future should be at university level with a diploma in cytotechnology certified or accredited by the European Federation of Cytology Societies. CONCLUSION: The survey showed variation in basic education and cytology training, especially with respect to non-gynaecological cytology, although graduate entry was favoured. The role of CTs is changing and the education and training programmes need to adapt to these changes.

Essential requirements for setting up a stem cell processing laboratory.

The Graft Processing subcommittee of the Worldwide Network for Blood and Marrow Transplantation wrote this guideline to assist physicians and laboratory technologists with the setting up of a cell processing laboratory (CPL) to support a hematopoietic stem cell transplant program, thereby facilitating the start-up of a transplant program in a new location and improving patient access to transplantation worldwide. This guideline describes the minimal essential features of designing such a laboratory and provides a list of equipment and supply needs and staffing recommendations. It describes the typical scope of services that a CPL is expected to perform, including product testing services, and discusses the basic principles behind the most frequent procedures. Quality management (QM) principles specific to a CPL are also discussed. References to additional guidance documents that are available worldwide to assist with QM and regulatory compliance are also provided.

Rapid on-site evaluation of fine needle aspiration specimens by cytology scientists: a review of 3032 specimens.

OBJECTIVES: To determine: (1) the accuracy of cytology scientists at assessing specimen adequacy by rapid on-site evaluation (ROSE) at fine needle aspiration (FNA) cytology collections; and (2) whether thyroid FNA with ROSE has lower inadequacy rates than non-attended FNAs. METHODS: The ROSE of adequacy for 3032 specimens from 17 anatomical sites collected over a 20-month period was compared with the final report assessment of adequacy. ROSE was performed by 19 cytology scientists. The report profile for 1545 thyroid nodules with ROSE was compared with that for 1536 consecutive non-ROSE thyroid FNAs reported by the same cytopathologists during the study period. RESULTS: ROSE was adequate in 75% (2276/3032), inadequate in 12% (366/3032) and in 13% (390/3032) no opinion was rendered. Of the 2276 cases assessed as adequate by ROSE, 2268 (99.6%) were finally reported as adequate for assessment; eight specimens had adequacy downgraded on the final report. Fifty eight per cent of cases with a ROSE assessment of inadequate were reported as adequate (212/366), whereas 93% (363/390) with no opinion rendered were reported as adequate. The overall final report adequacy rate for the 3032 specimens was 94% (2843/3032). Confirmation of a ROSE of adequacy at reporting was uniformly high amongst the 19 scientists, ranging from 98% to 100%. The inadequacy rate for thyroid FNAs with ROSE (6%) was significantly (P < 0.0001) lower than for non-ROSE thyroid FNAs (17%). A significantly (P = 0.02) higher proportion of adequate ROSE thyroid specimens was reported with abnormalities, compared with non-ROSE thyroid collections. CONCLUSIONS: Cytology scientists are highly accurate at determining specimen adequacy at ROSE for a wide range of body sites. ROSE of thyroid FNAs can significantly reduce inadequate reports.
