Health technology assessment: Choice between a cytotoxic safety cabinet and an isolator for oncology drug reconstitution in Tunisia.

INTRODUCTION: In order to implement a centralized cytotoxic reconstitution unit (CCRU), a study was conducted to compare the implementation costs of a CCRU equipped with a cytotoxic safety cabinet (CSC) and one equipped with an isolator with negative pressure. MATERIALS AND METHODS: This study compares items such as infrastructure, air treatment and CCRU qualification costs, equipment's purchase and qualifications costs, as well as staff dressing costs. Two plans were elaborated according to the international recommendations in a way that they respond to the necessary requirements in both cases. Requests for quotes for the compared items were sent to different suppliers. RESULTS: The implementations' cost of a CCRU equipped with a CSC is cheaper than the one equipped with an isolator. The price of an isolator is much higher than a CSC; its qualification is also more expensive. However, the requirements and the costs for the air treatment and the dressing of the staff are less in the case of an isolator. The overall cost of the CCRU's implementation is approximately 1.3 times higher in the case of an isolator. However, by excluding the equipment purchase cost, the overall cost of a CSC's implementation becomes higher. CONCLUSION: For Tunisia, it seems that the CSC is the most adapted. However, this work should be completed by the comparison of the CCRU's operating costs in order to optimize the resources and figure out the cheapest system.

Parenteral Nutrition Complications in Children Undergoing Bone Marrow Transplantation.

BACKGROUND: Parenteral nutrition (PN) seems to be a practical solution to face the negative nutritional effects of bone marrow transplantation. OBJECTIVE: Report and describe all observed PN-related complications in children undergoing allogenic bone marrow transplantation in a tertiary center and determine the possible risk factors. MATERIALS AND METHODS: This was a retrospective and observational study including 51 allografted children 2 to 17 years of age. We collected from medical patient records any noticed PN-related complications using an assessment causality method. The independent risk factors for complications were investigated by multivariate analysis. RESULTS: A total of 92% of patients (n=47) developed a total of 136 complications attributable to PN. The incidence rate of complications was 5 for 100 patient days of PN. Infectious complications (32.3%) and electrolytic disorders (27.9%) were the most common conditions identified during our study. Multivariate analysis showed that the duration of PN exposure, age, and hyperglycemia were the risk factors for the onset of these complications. CONCLUSIONS: Although we have noticed multiple complications attributable to PN, a certain causal link is difficult to establish in this particular context. Emphasizing enteral nutrition in bone marrow graft protocols would be the best way to avoid these complications.

Direct cost analysis of the second year post-allogeneic hematopoietic stem cell transplantation in the Bone Marrow Transplant Centre of Tunisia.

Background: Hematopoietic stem cell transplantation (HSCT) is a medically complicated therapy with a long recovery time. In Tunisia, the National Health Insurance Fund (CNAM) covers only the first year post-transplantation, after which the costs are borne by the hospital. Objective: Describe complications that can occur during the second year post-allogeneic HSCT and calculate direct costs in different groups of patients. Methods: In this pharmacoeconomic study, medical records of the second year post-allogeneic HSCT were collected. Studied variables included frequent observed complications and medical and non-medical direct costs. Results: The average total direct cost in the population during the second year post-transplantation was $11,571, 97% of which represents direct medical costs Drugs accounted for the largest share (80%) of total direct costs, dominated by the cost of antifungals (52%) and antivirals (26%) drug . Cytomegalovirus status was seen in 9.3% of patients and was associated with a seven-fold increase in direct costs (p < 0.001).​​In patients who developed chronic GVHD, the average direct cost was three times higher than for those who did not (p = 0.032). Conclusion: Given the importance of direct costs in the post-transplantation period a review of the hospital financing mechanism and a new convention with the CNAM is crucial.​​.
