Abstract
Background
Laboratory staff handling blood or biological samples are at risk for accidental injury or exposure to blood-borne pathogens. Hepatitis B virus (HBV) vaccinations for laboratory staff can minimize these risks.
Objective
The aims of this study were to determine the prevalence of occupational exposure to needle stick injuries (NSIs) and assess HBV vaccination coverage among clinical laboratory staff in Sana’a, Yemen.
Methods
A cross-sectional survey was conducted among clinical laboratory staff who were involved in handling and processing laboratory samples at the main public and private clinical laboratories in Sana’a. Data collection was done using a semistructured questionnaire. The questionnaire was divided into 3 parts. Part 1 included information on sociodemographic characteristics of participants. Part 2 included information on the availability of the personal protective equipment in the laboratories, such as lab coats and gloves. Part 3 included questions about the history of injury during work in the laboratory and the vaccination status for HBV.
Results
A total of 219/362 (60%) participants had been accidentally injured while working in the laboratory. Of those, 14.6% (32/219) had been injured during the last 3 months preceding the data collection. Receiving the biosafety manual was significantly associated with lower risk of injury. Out of those who were injured, 54.8% (120/219) had received first aid. About three-quarters of respondents reported that they had been vaccinated against HBV. The vaccination against HBV was significantly higher among laboratory staff who were working at private laboratories (P=.01), who had postgraduate degrees (P=.005), and who received the biosafety manual (P=.03).
Conclusions
Occupational exposure to NSI is still a major problem among laboratory staff in public and private laboratories in Sana’a, Yemen. The high incidence of injuries among laboratory staff and the low rate of receiving first aid in laboratories combined with low vaccination coverage indicates that all laboratory staff are at risk of exposure to HBV. Therefore, strengthening supervision, legalizing HBV vaccinations for all laboratory staff, and optimizing laboratory practices regarding the management of sharps can minimize risks and prerequisites in Yemen.
