    (Addis Ababa University, 2020-06) Alemu Biruk; Ensermu Matiwos
    This study gives the reader a deeper insight into the impacts of waiting line systems application in relationship to improving the customer satisfaction and the general performance of the public services organization. The objective of the study was to assess such things as customer arrival and waiting time management system application as a factor for enhanced customer satisfaction. The methodologies used for data collection were site observation, in which structured observation check lists were used, a pre-tested/ adopted questionnaire and scheduled interview questions. For the site observation an entire customers randomly visiting the centers within the sampled time intervals have been accounted taking systematically every 3rd customer for data collection. A sample of 370 customers was taken for the data collection. The queue variables used under the study were perceived waiting time, actual service time, services quality, rate of customers’ compliance and the queue discipline before and after the application of WLS. Scheduled Interview questions were presented to three branches managers of Addis Ababa Drivers and Vehicles Licensing and Control Authority to assess impact of the queue management system has had on to improve customers satisfaction reducing the actual situation of customer waiting lines at, the compliance rate of clients after and before the application of the system, and the planed actions. For the analysis of the data, observational interpretation data collected using various software's like SPSS. Single queue-multiple server model of queue analysis was used, while frequency tables, graphs and correlation analysis were used for analyzing the data collected through questionnaire. Imagining about the many times someone had to wait in line in the last month or year and the time and the frustration that was associated with those waits has become a central concern to this study in line with its impact on the customers satisfaction. The study stipulated that application of the Queue Management System is one of the remedial solutions to enhance the overall organizational performance and above all boost customers’ satisfaction in public services organizations. To keep their organizational reputation, Public sectors as well as the Private business organizations have to increase their customers’ satisfaction by delivering instant and timely services. In services, waiting has great impact on service level and customer satisfaction. Consequently, in time-based competition, one of the main objectives of service companies is to minimize customer waiting and thus the ultimate management objective should be the maximization of customer satisfaction implementing time efficient technologies such as Waiting Line Management systems. Therefore, the managers can use the results in process mapping and improvement areas to improve their customers’ satisfaction by limiting waiting time, reducing customers’ compliance and enhancing services quality. As service capacity increases, there is a reduction in the number of customers in the line and in their waiting times, which decreases queuing cost and compliance.

    (Addis Ababa University, 2024-06) Alemu Biruk; Alferid Fetiya (Phd,MD; Hulala Faiza
    Background:Post spinal hypotension is defined as a decline in mean arterial pressure (MAP) of more than 20%from baseline or systolic BP <90mmHG with in 20minutes of spinal anesthesia. Its prevalence ranges from 30.1-71.5%.Hypotension may pose serious risks like loss of consciousness and cardiac arrest on mothers under goingCS under spinal anesthesia. Objective: To assess the incidence and risk factors of post-spinal hypotension among patient sundergoing cesarean section at Tikur Anbessa Specialized teaching Hospital, Addis Ababa,Ethiopia. Methodology: An institution-based prospective cross-sectional study was conducted using 262 obstetric patients admitted to TASH from November 2024 to May 2024. Data was entered and cleaned and analyzed using SPSS version 26. Association between categorical variables was determined using correlation logistic regression. Odds ratio was calculated on variables to determine association through binary and multivariate logistic regression.Those with P-value of 0.25 from binary logistic regression were brought to multivariableanalysis and independent variables with P-Value less than 0.05 was regarded as a risk factor for Results: Among 262 patients, 157 (60%) AOR 0.6353, 95% CI 0.0438-1.213 had post spinal hypotension following spinal anesthesia. Of which at 5% level of significance after multivariate binary logistic regression analysis, the odds of developing post spinal hypotension for gravidity<3 with P-value of 0.041 AOR 0.579, 95% CI (0.343-0.977), Supine patient position with P-value of 0.004 AOR 2.149 with 95% CI (1.271-3.633), No Use of spinal additive with P-value of0.008 AOR 0.456 with 95% CI (0.255-0.814). Conclusion and recommendation:The incidence of hypotension to be 60% which shows that more than half of mothers receiving spinal anesthesia are developing hypotension, which is a significant figure and a big concern for safe modern anesthetic practice.Although study on this particular area is sensitive and resource intensive, further multicenter studies are needed to better understand these factors, for provision of safe anesthesia in modern obstetric practice.
