Inter-technician and between-laboratory differences, especially during the evaluation of sperm morphology, have been a major cause of concern. The study aimed to develop an intensive training programme with intervals of continuous quality control assessments for sperm morphology. Twenty andrology laboratories from sub-Saharan Africa were invited to participate in a World Health Organization Spe...

BACKGROUND The ankle brachial index (ABI) is a well-established tool for screening and diagnosis of peripheral arterial disease (PAD). In this study we assessed the validity of ABI determination using a pocket Doppler device compared with automatic vascular laboratory measurement in patients suspected of PAD. METHODS Consecutive patients with symptoms of PAD referred for ABI measurement betwe...

The home ventilator market has grown in size and complexity. The aim of this study was to determine if common home ventilators are user-friendly for trained intensive care unit (ICU) physicians. Eleven ventilator models were tested by 13 ICU physicians without practical experience in home mechanical ventilation. Six tests were defined (start-up, unlocking, mode and setting recognition, mode cha...

PURPOSE The contamination rates associated with the preparation of medium-risk i.v. admixtures in a traditional practice site and in a class 1000 cleanroom were compared. METHODS Simulated product media fills served as the samples. Each investigator, a pharmacist and a pharmacy technician, prepared 500 vials and 500 small-volume parenteral (SVP) bags in five separate runs at a traditional pra...

Point-of-care (POC) CD4 testing was implemented at a stand-alone HIV voluntary testing and counseling centre in Harare, Zimbabwe. To validate the use of this new technology, paired blood samples were collected from 165 patients either by a nurse or a laboratory technician and tested using POC and conventional laboratory CD4 machines. Finger prick (capillary) blood was collected directly into th...

To BETTER L’XDERSIAND THE M-ORK THAT library technicians can and should do in libraries, the formal programs that train library technicians are discussed. Library technicians are trained to carry out much of the dayto-day operations of libraries. The curriculum from Seneca College of Applied Arts and Technology, the largest library technician program in Canada, is used to show that the training...

The technician routing and scheduling problem consists in routing and scheduling a crew of technicians in order to attend a set of service requests, subject to skill, tool, and spare part constraints. In this study we propose a formal definition of the problem and present a constructive heuristic and a large neighborhood search optimization algorithm.
