Analysis of Biosafety Performance in Selected Hospital Medical Laboratories in Karachi, Pakistan

Abstract

This study assessed biosafety performance between 5 selected private-sector hospital medical laboratories in Karachi, Pakistan. A 40-question questionnaire was distributed among 120 technical staff to better understand the practices and awareness level of technical staff in place. To assess the supply of biosafety facilities and equipment to keep laboratory workers and the surrounding environment safe from an outbreak of infectious diseases, a checklist was designed. After securing informed consent, the researcher anonymously interviewed technical staff from all sections of the pathology laboratory, filled out the standard questionnaire, and completed the checklist through personal observations. Biosafety awareness recorded among 5 laboratory technical staff was moderate (72%). Major gaps identified with reference to biosafety measures were in administrative controls, standard microbiological practices, and facility design/secondary barriers. The gaps included the following: the biosafety officer is appointed in only 1 laboratory, standard operating procedures are not in place in 3 laboratories, no training protocol is defined for staff, no immunization record is maintained, and incident reporting and recording is lacking at most laboratories. There is an adequate supply of simple personal protective equipment like gloves, goggles, masks, and lab coats. However, complex equipment, such as eyewash stations and biological safety cabinets, is not available in many laboratories. In Karachi, Pakistan, biosafety performance is compromised in most of the laboratories, but better performance also is demonstrated by laboratories that are accredited and certified.

Association Between Risk Factors and Prevalence of Musculoskeletal Disorders Among Laboratory Professionals - an European Perspective

“…Characteristic results for specific geographic areas may be related to cultural characteristics and traditional customs. In our study, respondents with university education have the highest presence (59.4%), which is consistent with the research of Aksoy et al ( 16 ) (57.2%), while Muhammad et al ( 17 ) (82.5%), Tobin et al ( 18 ) (82.1%) and Al-Abhar et al (82%) ( 15 ) found a higher presence. This result is a consequence of the introduction of higly sophisticated technologies and methods, as well as the quality of services, but also the limitation of competencies of laboratory technicians.…”

Strengthening laboratory biosafety in Liberia during the COVID-19 pandemic: Experience from the Global Laboratory Leadership Programme

“…Regardless of the past work experience and laboratory setting type, the baseline knowledge of all participants concerning biosafety and risk assessment was low. Similar results were reported in other biosafety training programs in different settings [ [13] , [14] , [15] , [16] ]. Our workshops were effective in delivering the fundamental concepts of biosafety in the context of SARS-CoV-2 as evidenced by the significant improvement in the post test scores.…”
