“…In addition, the discordance may be related to sample size; those studies used a relatively large sample size (minimum 97,618 samples) compared with the current study which may dilute the findings. On the contrary, the overall frequency of errors in this study is lower than studies conducted in Gondar, Ethiopia 23 and Wolega, Ethiopia 36 with defect rates of 36.8% and 58.2%, respectively. This discrepancy might be due to the smaller sample size, the inclusion of various working units in both studies, and the variability of the QIs included.…”

“…In this study, the most frequent errors were reported in the pre‐analytical phase (75.8%), followed by the post‐analytical phase (22.3%).

In this study, the post-analytical error was 25.2%, which is higher than the studies done in Dessie, Ethiopia (12.8%) 36 and Gondar, Ethiopia (9.3%). 23 The magnitude of error reported in the analytical phase was 11.1%, which is higher than a study done in Dessie, Ethiopia (3.5%).…”

Background and AimsAssuring laboratory quality by minimizing the magnitude of errors is essential. Therefore, this study aimed to assess hematology laboratory performance in the total testing process using quality indicators and sigma metrics.MethodsA cross‐sectional study was conducted from April to June 2022. The study included a total of 13,546 samples. Data on included variables were collected using a checklist. Descriptive statistics were used to present the overall distribution of errors. Binary logistic regression models were applied. Furthermore, using a Sigma scale, the percentage of errors was converted to defects per million opportunities to assess laboratory performance. Finally, the defect per million opportunities was converted to a sigma value using a sigma calculator.ResultsOf the 13,546 samples and corresponding requests, the overall error rate was 123,296/474,234 (26%): 93,412/47,234 (19.7%) pre‐analytical, 2364/474,234 (0.5%) analytical, and 27,520/474,234 (5.8%) post‐analytical. Of the overall errors, 93,412/123,296 (75.8%), 2364/123,296 (1.9%), and 27,520/123,296 (22.3%) were pre‐analytical, analytical, and post‐analytical errors, respectively. The overall sigma value of the laboratory was 2.2. The sigma values of the pre‐analytical, analytical, and post‐analytical phases were 2.4, 4.1, and 3.1, respectively. The sample from the inpatient department and collected without adherence to the standard operating procedures (SOPs) had a significantly higher (p < 0.05) rejection rate as compared to the outpatient department and collected with adherence to SOPs, respectively. In addition, an association between prolonged turnaround times and manual recording, inpatient departments, and morning work shifts was observed.ConclusionThe current study found that the overall performance of the laboratory was very poor (less than three sigma). Therefore, the hospital leadership should change the manual system of ordering tests and release of results to a computerized system and give need‐based training for all professionals involved in hematology laboratory sample collection and processing.

Background and Objective: Thyroid specimens constitute a major bulk of the head and neck surgical specimens received at the Pathology Departments. Careful handling of the specimens in the grossing room will result in an efficient reporting of useful histological parameters required for patient management and prognosis. The objective of this study was to analyze different errors and near-miss events in the grossing of thyroid specimens in the surgical pathology gross room of a Tertiary Care Hospital in Lahore, Pakistan. Methods: A cross-sectional analysis was done on different thyroid specimens received at the Pathology reception of Lahore General Hospital, Lahore, Pakistan, from January 2022 to April 2023. Different types of errors involved in standard gross examinations were studied. Data were entered using SPSS version 23.0. Results: Errors observed in the preanalytical phase included the use of inappropriate fixative (15.2%), insufficient clinical information (76.5), mislabeled jar/request form (7.6%), and loss of specimen (8%). Grossing errors included insufficient grossing notes (12.2%), cutting thick slices (10.7%), missing lesions on gross examination (9.9%), inappropriate inking (6.9%), overfilling cassette with large tissue sections (6.9%), mislabeled cassettes (93.8%), and incomplete submission of capsule (2.3%). Conclusion: This study concludes that errors and near-miss events in handling thyroid specimens can be avoided by effective training of the handling staff and grossing residents. Collaboration between clinical wards and histopathology laboratories can also be helpful in this regard.
