Oral cavity cancers are part of the upper aerodigestive tract cancers and represent a significant burden worldwide. Its epidemiology varies from country to country with high frequencies in South East Asian countries. Tobacco and alcohol are the main risk factors. Survival of oral cancer is low i.e., less than 40% in the advanced stage (stage III and IV), diagnosis of oral cavity cancer is based on a complete clinical examination of the oral cavity complete with biopsy, bio-markers are an adjunct to screening and diagnosis of oral cavity cancers, surgery, radiotherapy, chemotherapy and immunotherapy are part of the therapeutic armamentarium of oral cancer but also have limitations. Traditional medicine is an important and proven alternative in the treatment and support of patients with oral cavity cancer. Prevention of oral cavity cancers includes not only early detection of precancerous and cancerous lesions but also control of risk factors and education of the population. Surgery, radiotherapy, chemotherapy and immunotherapy are part of the therapeutic strategy of oral cancer treatment but also have limitations. Traditional Medicine is an important and proven alternative in the treatment and support of patients with oral cavity cancer. It is thus desirable to scientifically validate phytochemicals in order to integrate alternative medicine as part of national cancer management strategy. In silico advanced studies on secondary metabolites of medicinal plants traditionally used to treat oral cancer are in progress.

The evaluation of the quality of a service is the critical assessment of the degree to which the service, or its component, provides customers’ satisfaction. Monitoring customer satisfaction is an important and useful quality improvement tool for clinical laboratories and health care organizations. The purpose of this research is to evaluate the satisfaction level with laboratory services among attending physicians and to identify factors associated with satisfaction and priorities for quality improvement. A cross-sectional study was conducted at the University Hospital of Kinshasa. Data were collected through a reliable and valid interviewer-administered questionnaire and analyzed by using SPSS version 21. The correlation between associated factors and customer satisfaction was analyzed using the chi-square test and multivariate regression analysis. The Importance-Performance Analysis was the determinant of improvement priority. The overall level of customers’ satisfaction toward clinical laboratory services in this study was 45.2% with a response rate of 330 (100%). Gender (ORadj = 1.75, 95% CI 1.06, 2.91), Department (ORadj = 3.09, 95% CI 1.50, 6.37) and academic title (ORadj = 6.85, 95% CI 3.51, 8.81) were found to have a statistically significant association with the overall satisfaction. Results accuracy (I = 0.944, P = 4.7), laboratory turnaround time (I = 0.932, P = 4.8), and availability of all the tests requested by physicians (I = 0.917, P = 4.9) were the most important opportunities for quality improvement. The overall level of customers’ satisfaction with laboratory services was low. Thus, the laboratory management must establish preventive and corrective measures to improve the results’ accuracy, reduce the laboratory turnaround time, and ensure the availability of all the tests requested by physicians.

In Democratic Republic of the Congo (DRC), the laboratory TAT is significantly very long and do not comply with either international standards or the suggestions of customers. However, there is neither a national nor a local strategy to improve the laboratory TAT. The aim of the present study is to develop practical management strategies to shorten clinical laboratory tests' TAT. This was a qualitative study conducted in Kinshasa. Focus groups and Lean tools were used respectively to generate a wide range of views from a variety of laboratory staff and to eliminate several form of waste in the laboratory flow process. Based on the identified root causes of delay, focus groups participants reported that there is a lot of scope for the improvement of TAT in DRC. Consistent attendance and punctuality are essential. The hospital management should implement the Laboratory Information Systems (LIS) and install Middleware. Total laboratory automation, inventory system for all reagents and supplies used in the laboratory, expansion of the sampling area,

Background and aim: Oral cancer remains a public health problem with a high morbidity and mortality rate. The aim of this study was to determine the level of knowledge, attitude and practice of Kinshasa dentists on oral cancer. Patients and Method: This cross-sectional, descriptive study was conducted in public and private hospitals in the provincial city of Kinshasa between October 2019 and June 2020. A total of 143 dentists responded to the survey. The questionnaires included knowledge of risk factors, attitude and practice of Kinshasa dentists. Results: The average age of the participants was 34.05 ± 7.31 years, the male gender was the most represented (69.2%), and the level of knowledge of the dentists about the risk factors was low despite the fact that the majority of the participants in the study had recognized alcohol (77.5%) and tobacco (77.6%) as the main risk factors for oral cancer. The majority of the participants referred the patient to a specialist upon discovery of a cancerous lesion, only a minority of dentists performed biopsy and counselling. Conclusion: The level of knowledge of Kinshasa’s dentists about oral cancer is low. Refresher training is necessary to enable them to raise their level of knowledge. Thus, the reinforcement of cancer courses in the dental sector is important for a better management of cancer patient.

The delay in the delivery of laboratory results can be fatal and can even lead to the death of patients. This study was conducted at the clinical laboratory of the University Hospital of Kinshasa (UHK) from October 2020 to April 2021, aimed to evaluate the laboratory tests' turnaround time (TAT) and to identify reasons for delay. TAT was quantified using a time and motion analysis approach. The evaluation of TAT consisted of comparing the overall intra-lab TAT with the suggested TAT using student t-test at 95% confidence intervals. Brainstorming was the root cause analysis tool used for identifying reasons for delay. In this study, the laboratory tests' TATs were significantly higher (p < 0.001) comparing to international guidelines (60 minutes) and customers' suggested TAT (120 minutes). Only 0.98% of the samples were reported within 60 minutes of patient reception and 1.47% within 120 minutes, i.e. an outlier rate of 98.5%. Root causes of delay related to Machinery, Management, Manpower, Materials, Method and Milieu. Because of many reasons, the laboratory is not meeting the established TAT. Preventive and curative measures must be undertaken to reduce the delay and improve the TAT.
