The aim of this study was to assess the capacity of the Katuba district hospital to address felt needs for hospitalization of patients. To do it, information on the activity of hospitalization contained in the registers of patients and the reports of the district medical officer were collected and used to determine indicators related to the hospitalization. The queuing model was used to determine the daily characteristics of the hospitalization. As results, the initial bed occupancy rates in different inpatient services were 162 % in the pediatrics ward, 98 % in the maternity, 97 % in the surgery ward, 43 % in the male internal medicine ward and 43 % in the female internal medicine ward. According to needs of hospitalization, redistribution of beds was proposed and returned the above bed occupancy rates respectively to 94 %, 94 %, 87 %, 91 % and 85 %. The queuing model applied on each inpatient service revealed that the daily average numbers of patients awaiting an available bed are respectively of 9, 11, 4, 8, and 4, with a waiting time respectively estimated at 2,26 ; 2,69 ; 6,1 ; 8,16 and 5,48 days. Definitely, disparities of the initial bed occupancy rates highlight an inefficient distribution of beds between inpatient services, and the fact that patients wait for days before being admitted to hospital indicates that the capacity of the hospital is insufficient and should be improved.

During this study, we used the professional risk, pension service and financial sheets of two directorates of the National Institute of Social Welfare of Haut-Ktanga for the study of different variables. In total, we analyzed 251 cases and of which the year 2012 recorded more accidents at work than other years, ie 32.3%. The male sex represents 92.8% of the accidents at work. The married are the most rugged, almost 95%. The seniority range from 2 to 7 years is the most accident-stricken with 38.2% of cases. The mining sector is the most rugged sector with 70.1%. Married people are the most rugged, about 95% of the population of our study. The seniority period ranging from 2 to 7 years experienced many more accidents, ie 38.2% of the cases. The mining sector is the most rugged sector with 70.1% and the miners are the most rugged of our study with 52%. The total costs of care and compensation have increased overall over the 2008-2012 period with a peak in 2010 of more than 250 million CDF. On the other hand, the compensation costs do not depend on the accident sector, the places where the accidents occurred and the age of the victims.
