Hospital meal carts are used to deliver meals,
drugs and some other materials to patients in the hospital
environment. These carts which are moved manually by
operators, the health workers, mostly do not comply with
ergonomics guidelines and physical requirements of the
equipment users in terms of anthropometry data of the
region thus increasing the risk of musculoskeletal disorder
among the meal cart users. This study carried out ergonomic
evaluation of the available meal carts in some
western Nigeria hospitals. A well-structured questionnaire
has two major segments: Operational survey and biomechanical
survey, which were administered to the health
workers using hospital meal carts in some hospitals in
southwestern Nigeria, and physical assessment, which was
undertaken to collect data for the ergonomic evaluation.
The responses from the questionnaires show that some
areas on the existing hospital meal carts are of concern to
the users which need to be improved upon.
