Evaluation of errors in a clinical laboratory: a one-year experience

Abstract

Background: Efficient laboratory service is the cornerstone of modern health care systems. Scientific innovations have contributed to substantial improvements in the field of laboratory science, but errors still prevail. These errors are classified as preanalytical, analytical and postanalytical, depending upon the time of presentation. Methods: The data for 67,438 routine venous blood specimens were scrutinized, and errors were documented over the period of 1 year in the clinical biochemistry laboratory of Govind Ballabh Pant Hospital in Delhi, India. Results: Preanalytical errors were most common, with a frequency of 77.1% followed by postanalytical 15% and analytical 7.9%, respectively. Conclusions: Our study illustrates the importance of proper venipuncture procedures, analytical expertise and correct transcription of numerical data for precise and accurate reporting of results to clinicians. There is an urgent need for close inter-departmental cooperation to meet the goal of ensuring patient well being.

Evaluation of Preanalytical Errors in Clinical Biochemistry Laboratory in a Tertiary Care Hospital in Kolkata

“…10 Similarly, Goswami et al found that the pre-analytical errors were the most commonly encountered, with a frequency of 77.1% followed by post analytical accounting for 15% and analytical contributing upto 7.9% 11 In a survey on outpatient phlebotomy procedure, most unsuitable samples resulted from haemolysis (18.1%), insufficient quantity (16.0%), and clotting (13.4%) 12 These data are comparable to those provided by additional investigations, which confirm that problems directly related to specimen collection are the main causes of preanalytic errors, especially haemolysed, clotted, insufficient, and incorrect samples. [13][14][15][16] In our study, there was a high percentage of errors in the requisition slips.…”

Principais parâmetros biológicos avaliados em erros na fase pré-analítica de laboratórios clínicos: revisão sistemática

“…Podemos observar que a etapa laboratorial com maior concentração de erros foi a fase pré-analítica. Goswami et al (11) coletaram dados durante um ano e tiveram alto índice de 77% de falhas nessa área. Os trabalhos de Plebani e Carraro (25) (6) …”

Pengembangan Laboratory Information System untuk Memperbaiki Waktu Tunggu Layanan

“…efisien ditandai oleh 3 hal yaitu presisi, akurat, dan Rerata TAT, standar deviasi, nilai maksimum dan minimum ketepatan waktu yang dinilai dengan turnaround time (dalam menit) pada masing-masing waktu tunggu (TAT) (2,3). Turnaround time sering digunakan oleh klinisi dianalisis pada pasien rawat jalan dan rawat inap.…”

“…Hasil perhitungan waktu tunggu masing-masing tahap dengan hasil dilaporkan (3,4 Diagram fishbone digunakan untuk menentukan akar masalah pemanjangan TAT. Pada faktorman, jumlah sumber daya manusia (SDM) terutama analis kesehatan terpenuhi sesuai dengan analisis beban kerja serta standar pendidikan minimal yang telah ditetapkan.…”

“…bahwa 11% dari spesimen yang diperiksa di laboratorium Pada pasien rawat jalan pemakaian LIS dapat mengurangi tidak selesai sesuai dengan batas waktu yang telah pemanjangan TAT secara signifikan pada pemeriksaan ditentukan (7). Ketepatan waktu sangat penting bagi klinisi kimia klinik (161,84±129,90 menit;95%CI 119,54; yang mungkin dapat mengorbankan kualitas analisis untuk p<0,0001) dan keduanya (94,90±34,35 menit; 95%CI TAT yang cepat, namun para profesional laboratorium 71,83-117,99; p<0,0001), namun pada pemeriksaan lebih memilih menjaga kualitas analisis sama baiknya laboratorium darah lengkap di rawat jalan tidak terdapat dengan mengurangi TAT (3). Pengurangan TAT seharusnya perbedaan bermakna (157,00±63,64 menit; 95%CI -dapat meningkatkan kualitas pelayanan.…”
