Evaluating the cost-consequence of a standardized strategy for the etiological diagnosis of uveitis (ULISSE study).

MAIN OBJECTIVE: To prospectively assess the cost-consequence of a standardized diagnostic strategy as to compared to an open one for the etiological diagnosis of uveitis. DESIGN: This was a prospective, non-inferiority, multicentre, randomized controlled trial. METHODS: We included all consecutive patients with uveitis who had visited at least one of the Departments of Ophthalmology. In the standardized group, patients had a minimal work-up regardless of the type of uveitis (including evaluation of the CBC, ESR, C-reactive protein, tuberculin skin test, syphilis serology and chest X-ray). Depending on ophthalmological findings, further investigations could be performed. In the open strategy, ophthalmologists were free to order any kind of investigation. The main outcome was the mean cost per patient of each strategy. RESULTS: 903 uveitis patients were included from January, 2010 to May, 2013. The mean cost per patient of the standardized strategy was 182.97 euros [CI 95% (173.14; 192.80)], and the mean cost per patient of the open strategy was 251.75 euros [CI 95% (229.24; 274.25)]. Therefore, the mean cost per patient of the standardized strategy was significantly lower than the mean cost per patient of the open strategy (p<0.001). There were significantly fewer visits (p<0.001), fewer radiological procedures (p<0.004) and fewer laboratory investigations (p<0.001) in the standardized group. CONCLUSION: A standardized strategy is a cost-saving approach for the etiological diagnosis of uveitis.

Current practice compared with the international guidelines: endoscopic surveillance of Barrett's esophagus.

RATIONALE, AIMS AND OBJECTIVES: To describe the current practice for the surveillance of patients with Barrett's esophagus, to compare this practice with the national guidelines published by the French Society of Digestive Endoscopy in 1998 and to identify the factors associated with the compliance to guidelines. METHOD: To determine the attitudes of French hepatogastroenterologists to screening for Barrett's oesophagus, a postal anonymous questionnaire survey was undertaken. It was sent to 246 hepatogastroenterologists in the Rhone-Alpes area. We defined eight criteria allowed to assess the conformity of practices with the guidelines. We created three topics composed of several criterion. The topics analysed were 'Biopsies', 'Surveillance' and the diagnosis of high grade dysplasia. We studied the factors which could be associated with the compliance with the guidelines. RESULTS: The response rate was 81.3%. For 58.0% of the gastroenterologists, endoscopic biopsy sampling were made according to French guidelines (four-quadrant biopsies at 2 cm intervals). Agreement was 78.0% regarding the interval of surveillance for no dysplasia (every 2 or 3 years) and 78.5% regarding the low-grade dysplasia (every 6 or 12 months). For the management of high-grade dysplasia, 28.6% actually confirm the diagnosis by a second anatomopathologist and 42.0% treated by proton pump inhibitor during 2 months. Concerning the biopsies, the young gastroenterologists and gastroenterologists practising in university hospitals had a better adherence to the guidelines (Relative Risk: 2.22, 95% CI 1.25-3.95 and 3.74, 95% CI 1.04-13.47, respectively). The other factors of risk were not statistically significant. CONCLUSIONS: The endoscopic follow-up is mostly realized in accordance with the national guidelines. However, there is a wide variability in individual current practice.

Estimated numbers of postmenopausal women treated by hormone therapy in France.

OBJECTIVES: To estimate the number of women aged 50-69 years treated by hormone therapy (HT) in France before Women's Health Initiative's (WHI) results and to evaluate the potential decrease of HT prescriptions since the publication of WHI clinical trial. METHODS: We used data from eight computerized databases of French cohort studies providing information on HT and constituted by women aged over 50 years living in metropolitan France. From these, we used direct standardization on the French population to estimate the prevalence of HT users across 5 years age groups. Data from the National Health Insurance Agency on two time-periods November 2002-January 2003 and November 2003-January 2004 were used to evaluate the evolution of HT prescriptions since WHI's publication among women aged 50-69 years living in the Rhône-Alpes region. RESULTS: The crude prevalence of HT users among women aged 50-69 years was 52.3% (51.8-52.8) and corresponds to a standardized prevalence of 35.7% (35.1-36.4), that is about 2.56 (2.51-2.59) million women. Standardized prevalence was the highest in 50-54 years age group then it decreased significantly across the older age groups (p<10(-6)). HT reimbursements decreased significantly between the two studied time-periods in the Rhône-Alpes region (p<10(-6)) from -14 to -45%, depending on the considered age groups (65-69 or 50-54 years). CONCLUSIONS: Although WHI results have been criticized by French professional societies based on the fact that treatments used were different in France--mainly transdermal estrogens--and that French postmenopausal women were at lower vascular risk than those of the WHI, the release of this study had effect on the prescription before the French regulatory agency (AFSSAPS) edited limiting recommendations for HT prescription. Further efforts have to be made to collect systematically information on preventive treatments used at menopause followed by evaluation studies.

Estimated number of women likely to benefit from bone mineral density measurement in France.

OBJECTIVES: To determine the number of women in France at least 50 years of age with risk factors for osteoporosis likely to lead to bone mineral density measurement, an investigation reimbursed by the French national health insurance system in patients at risk for osteoporosis. The study was commissioned by the French health authorities. MATERIALS AND METHODS: Risk factors for osteoporosis were defined as recommended by the French Agency for Accreditation and Evaluation in Health (ANAES) in 2001. The study data were from nine cohort studies done in France and from the National Health Insurance Agency for the Rhone-Alpes region of France. Risk factor prevalences in France were standardized by extrapolation according to the age distribution in France. RESULTS: Overall, data were collected in 123,986 women aged 50 years or older. From these data, risk factor estimates were as follows: menopause before 40 years of age, 1.5 million women; body mass index (BMI) lower than 19 kg/m(2), nearly 700,000; history of fracture, more than 2 million; history of femoral neck fracture in the mother, more than 1 million; history of health problems potentially responsible for osteoporosis, 400,000; and history of long-term glucocorticoid therapy, 612,000. In all, 3,186,318 (30%) women were estimated to have at least one risk factor and 785,512 (7.5%) at least two risk factors. CONCLUSIONS: Although our study sample was not representative of the population residing in France, the large sample size and diversity of data sources support the validity of our estimate of the prevalence of risk factors for osteoporosis in postmenopausal women living in France.

In situ simulation training for neonatal resuscitation: an RCT.

OBJECTIVES: High-fidelity simulation is an effective tool in teaching neonatal resuscitation skills to professionals. We aimed to determine whether in situ simulation training (for ∼80% of the delivery room staff) improved neonatal resuscitation performed by the staff at maternities. METHODS: A baseline evaluation of 12 maternities was performed: a random sample of 10 professionals in each unit was presented with 2 standardized scenarios played on a neonatal high-fidelity simulator. The medical procedures were video recorded for later assessments. The 12 maternities were then randomly assigned to receive the intervention (a 4-hour simulation training session delivered in situ for multidisciplinary groups of 6 professionals) or not receive it. All maternities were evaluated again at 3 months after the intervention. The videos were assessed by 2 neonatologists blinded to the pre-/postintervention as well as to the intervention/control groups. The performance was assessed using a technical score and a team score. RESULTS: After intervention, the median technical score was significantly higher for scenarios 1 and 2 for the intervention group compared with the control group (P = .01 and 0.004, respectively), the median team score was significantly higher (P < .001) for both scenarios. In the intervention group, the frequency of achieving a heart rate >90 per minute at 3 minutes improved significantly (P = .003), and the number of hazardous events decreased significantly (P < .001). CONCLUSIONS: In situ simulation training with multidisciplinary teams can effectively improve technical skills and teamwork in neonatal resuscitation.
