Assessing the queuing process using data envelopment analysis:an application in health centres

Queuing is one of the very important criteria for assessing the performance and efficiency of any service industry, including healthcare. Data Envelopment Analysis (DEA) is one of the most widely-used techniques for performance measurement in healthcare. However, no queue management application has been reported in the health-related DEA literature. Most of the studies regarding patient flow systems had the objective of improving an already existing Appointment System. The current study presents a novel application of DEA for assessing the queuing process at an Outpatients’ department of a large public hospital in a developing country where appointment systems do not exist. The main aim of the current study is to demonstrate the usefulness of DEA modelling in the evaluation of a queue system. The patient flow pathway considered for this study consists of two stages; consultation with a doctor and pharmacy. The DEA results indicated that waiting times and other related queuing variables included need considerable minimisation at both stages

Konstrukcija i primenenie avtomaticheskogo mikrometricheskogo apparata dlja oboznachanija kontaktnykh insekticidnykh sredstv pri pomoshhi metoda "Topical application"

A description of an automatic micrometric apparatus constructed by the authors. The apparatus is served by an electric motor and an interval time disconnecting swith is used. Calibration of the apparatus showed a precision of dosage, determined by the use of the variability coefficient WZ=0,6-6,5%. Calibration was made by weight using hydrargyrum and colorimetric method to determine the dispersion of the size of the single drops. Crystal violet was used as the stain. Biological testing conducted on females of the house fly (Musca domestica L.) cultivated under laboratory conditions showed in the course of the determination LD50 - gamma HCH the accuracy WZ=9,7%
