[Corneal graft activity in France (1990-2005): decreasing the gap between supply and demand]

International audienceOBJECTIVE: To evaluate changes in the balance between supply and demand for corneal grafts over the last 15 years in France in the light of the measures implemented and the 2005 national and regional audit. Materials and methods: Corneal transplantation activities were estimated, mainly from a national prospective survey of ophthalmologists (1991-1994), annual surveys of ophthalmologists (1995-2000), tissue banks (1996-2005), and the national waiting list for surgery (since 2000). RESULTS: In 2005, the main indicators available were consistent with a stabilization in the number of candidates added to the waiting list every year (4606 in 2005), accompanied by a large increase in the number of grafts procured (9264 in 2005). There was also a substantial increase in quality testing of these grafts, leading to a high rate of rejection (49.5% of the procured grafts). In addition, the number of grafts exported decreased to a very low level (213 in 2005). The percentage of malades registered on the waiting list who received grafts in the same year also increased (68.5% in 2005). Once the waiting list had been updated, 3016 malades remained on the list at the beginning of July 2006. The gap between supply and demand for corneal transplantation has therefore narrowed. Two actions made particularly large contributions to these changes: the creation in 2000 of 120 full-time staff positions in hospital coordination teams, which has had a major impact on procurement rates; and the organization of the tissue bank sector, making it possible to guarantee the quality and distribution of grafts. CONCLUSION: Corneal procurement and transplantation activities seem to have reached equilibrium in France. A reliable estimation of demand, particularly at the regional level, has led the French agency in charge of tissue transplantation to modify the functioning of the national corneal transplant waiting list, with tissue banks now allowed access to declare transfers and the temporary registration of malades on the list to limit stagnation

Changing Kidney Allocation Policy in France: the Value of Simulation

This paper advocates the value of simulation to promote changes in kidney allocation. Due to the scarcity of organs and to the competition between transplantation centers to obtain the best organs for their patients, any change in organ allocation policy remains a sensitive issue in public health decision-making. Organ allocation is not easily available for prospective experimental study. Observational studies only support limited changes. A simulation tool in this context permits the comparison of observed results against simulated ones. In our experience in France, it has shown to be a helpful tool during the allocation design phase providing objective facts for the debates and increasing the potential for change

Remission after treatment of osteoarticular infections due to Pseudomonas aeruginosa versus Staphylococcus aureus: a case-controlled study

PURPOSE: Osteoarticular infections due to methicillin-susceptible Staphylococcus aureus (MSSA) or its methicillin-resistant variant (MRSA) are feared due to treatment failures. According to clinical experience, Pseudomonas aeruginosa may reveal less long-term remission than S. aureus. METHODS: A case-controlled study comparing outcomes of osteoarticular infections due to P. aeruginosa vs S. aureus was performed at Geneva University Hospitals. RESULTS: A total of 111 S. aureus (including 37 MRSA) and 20 P. aeruginosa osteoarticular infections were analysed in 131 patients: arthroplasties (n = 38), fracture fixation devices (n = 56), native joint arthritis (n = 7) and osteomyelitis without implant (n = 30). The median active follow-up time was 4 years. The patients underwent a median number of two surgical interventions for P. aeruginosa infections compared to two for S. aureus (two for MRSA), while the median duration of antibiotic treatment was 87 days for P. aeruginosa and 46 days for S. aureus infections (58 days for MRSA) (all p > 0.05). Overall, Pseudomonas-infected patients tended towards a lower remission rate than those infected with S. aureus (12/20 vs 88/111; p = 0.06). This was similar when P. aeruginosa was compared with MRSA alone (12/20 vs 30/37; p = 0.08). In multivariate logistic regression analyses adjusting for case mix, odds ratios (OR) for remission were as follows: P. aeruginosa vs S. aureus [OR 0.4, 95% confidence interval (CI) 0.1–1.2], number of surgical interventions (OR 0.6, 95% CI 0.5–1.0) and duration of antibiotic treatment (OR 1.0, 95% CI 1.0–1.0). CONCLUSIONS: Despite a similar number of surgical interventions and longer antibiotic treatment, osteoarticular infections due to P. aeruginosa tended towards a lower remission rate than infections due to S. aureus in general or MRSA in particular

The critical pathway for deceased donation:reportable uniformity in the approach to deceased donation

P>The critical pathway of deceased donation provides a systematic approach to the organ donation process, considering both donation after cardiac death than donation after brain death. The pathway provides a tool for assessing the potential of deceased donation and for the prospective identification and referral of possible deceased donors
