“…This practice may have accounted for the low SRR in this study. Some reports have concluded that the rates of pre-analytic errors are lower for outpatients, for whom phlebotomy procedures are performed by personnel under direct laboratory control [22] [23].…”

Background: In January 2010, the implementation of quality management systems toward WHO-AFRO laboratory accreditation commenced in the Antiretroviral Treatment Laboratory of the Infectious Disease Hospital, Kano, Nigeria. Quality improvement projects were instituted in 2011 in line with ISO 15189 requirements for accreditation of medical laboratory. In this study we evaluated the performance of the laboratory through some set of quality indicators (QI). Methodology: This was a retrospective study to evaluate laboratory QIs monitored from January 2011 to December 2013. The QIs were specimen rejection rate (SSR), turnaround time (TAT), proficiency testing performance (PTP) and client satisfaction survey (CSS). Data was collected into an excel file for analysis and percentage performance compared among years. SSR & TAT were evaluated with the Sigma scale. Results: A total of 7920 (2194 in 2011, 2715 in 2012, 3011 in 2013) specimens were received for testing. 22 (0.28%) specimens were rejected and 81 (1.02%) specimens' results were reported after the acceptable TAT, giving a Sigma level of 4.27 and 3.82 for SSR and TAT respectively. There was steady improvement in PTP: CD4+ from 67% in 2011 to 90% in 2013, hematology from 81% in 2012 to 83% in 2013, blood film reading 79% in 2011 to 83% in 2013 and chemistry from 90% in 2011 to 93% in 2013. HIV serology recorded 100% throughout. CSS increased from 59% in 2012 to 78% in 2013. However, there was no statistically significance difference reported for PTP and CSS over the years (P > 0.05). Conclusion: The study highlights the need to continuously evaluate QIs and calls for more effort to improve on PTP and focuses on understanding and improving on clients concerns.

“…Blood sampling by venipuncture for various laboratory analyses is one of the most invasive common procedures, yet at the same time most underrated procedures in a hospital setting ( 1 , 2 ). Although venipuncture is considered as safe and foolproof procedure for patients, several studies show that it carries inherent risks ( 3 , 4 ).…”

IntroductionThis study aimed to assess confidence level of healthcare professionals in venipuncture and their knowledge on the possible causes of in vitro hemolysis.Materials and methodsA sample of 94 healthcare professionals (nurses and laboratory technicians) participated in this survey study. A four-section questionnaire was used as a research instrument comprising general information for research participants, knowledge on possible causes of in vitro hemolysis due to type of material used and venipuncture technique and specimen handling, as well as assessment of healthcare professionals’ confidence level in their own ability to perform first and last venipuncture.ResultsThe average score on the knowledge test was higher in nurses’ than in laboratory technicians (8.11 ± 1.7, and 7.4 ± 1.5, respectively). The difference in average scores was statistically significant (P = 0.035) and Cohen’s d in the range of 0.4 indicates that there is a moderate difference on the knowledge test among the health care workers. Only 11/94 of healthcare professionals recognized that blood sample collection from cannula and evacuated tube is method which contributes most to the occurrence of in vitro hemolysis, whereas most risk factors affecting occurrence of in vitro hemolysis during venipuncture were recognized. There were no significant differences in mean score on the knowledge test in relation to the confidence level in venipuncture (P = 0.551).ConclusionConfidence level at last venipuncture among both profiles of healthcare staff was very high, but they showed insufficient knowledge about possible factors affecting hemolysis due to materials used in venipuncture compared with factors due to venipuncture technique and handling of blood sample.

Proper shipping of infectious materials is an important practice to prevent healthcare workers (HCWs), other people and environment from spread of biological threats. The main purpose of this study was to determine healthcare providers' knowledge, and practices about transportation of infectious substances. A self-administered designed questionnaire was used to collect relevant data from study respondents. Primary data were double entered and analyzed by using statistical package for social sciences (IBM SPSS statistics 20). Descriptive, in addition to the effects of predictors on dependent variables were applied. Multiple logistic regression model was used to assess the association between dependent variables and predictors. It has been found that; the overall mean percentage of knowledge was 57.1 (95 CI: 54.1, 60.2), while mean percentage of practice was 68.9 (CI: 95% 66.7 -71.1). Response reliability scale was 89.0% based on Cronbach's alpha. The highest knowledge regarding transportation of infectious substances was observed among laboratory specialist (33.9%) and doctors (25.4%) respectively. High percentage of practice was observed among laboratory specialist was (34.6%) and low percentage was among public health officers and doctors (15.9%). Majority of study respondents did not receive training in transportation of infectious substances (70.9%). Knowledge and practice on transportation of infectious substances among health care providers are low. More efforts are needed to fill the gap in knowledge and practice by applying effective training programs that can lead to increase skills and awareness of health care providers.
