Clinical course and cost assessment of infants with a first episode of acute bronchiolitis presenting to the emergency department: Data from the GUERANDE clinical trial.

INTRODUCTION: Bronchiolitis is the leading cause of hospitalization for infants but its economic burden is not well documented. Our objective was to describe the clinical evolution and to assess the 1-month cost of a first episode of acute bronchiolitis presenting to the emergency department (ED). METHODS: Our study was an epidemiologic analysis and a cost study of the cohort drawn from the clinical trial GUERANDE, conducted in 24 French pediatric EDs. Infants of 6 weeks to 12 months of age presenting at pediatric EDs with a first episode of bronchiolitis were eligible. The costs considered were collected from a societal viewpoint, according to the recommendations of the French National Health Authority. RESULTS: A total of 777 infants were included with a median age of 4 months. A total of 57% were hospitalized during the month following the first consultation in the ED, including 28 (3.6%) in an intensive care unit. The mean length of stay was 4.2 days (SD = 3.7). The average time to relief of all symptoms was 13 days (SD = 7). Average total cost per patient was €1919 (95% confidence interval: 1756-2138) from a societal perspective, mostly due to hospitalization cost. The estimated annual cost of bronchiolitis in infants was evaluated to be between €160 and €273 million in France. DISCUSSION: Bronchiolitis represent a high cost for the health care system and broadly for society, with hospitalizations costs being the main cost driver. Thus significant investments should be made to develop innovative therapies, to reduce the number of hospitalizations and length of stay.

Integrative clinical and biopathology analyses to understand the clinical heterogeneity of infantile rhabdomyosarcoma: A report from the French MMT committee.

BACKGROUND: Rhabdomyosarcoma (RMS) in infants is a particular entity with various clinical presentations and outcomes. To better understand the clinical heterogeneity of RMS in infants, an integrative clinical, histological, and molecular analysis was performed. METHODS: From 1989 to 2015, 37 infants aged less than 6 months with a diagnosis of RMS and archival tumor materials were identified in France. Clinical data, central pathologic review, and molecular profile including RNA sequencing were analyzed. RESULTS: Nineteen patients (51%) had embryonal RMS (ERMS) (including three highly differentiated ERMS with PTCH deletion), eight (22%) had spindle cell RMS (SRMS) (three VGLL2-, one NTRK-, and two (B)RAF-fusions), six (16%) had alveolar RMS (ARMS) (all FOXO1- or PAX3-fusion), two had unclassified RMS, and two poorly differentiated RMS were retrospectively diagnosed as rhabdoid tumors (RT) with loss of INI1 expression. The two RT patients died of rapid disease progression. Five-year event-free (EFS) and overall survival (OS) for RMS were 62% (95%CI, 47-82) and 52% (95%CI, 37-72). Eleven patients (31%) relapsed and four (11%) had primary refractory disease (all ERMS). In univariate analysis, EFS and OS were only associated with histology subtype, with 100% survival of known fusion-positive SRMS. RNA cluster expression showed three main clusters: ARMS, ERMS, and "VGLL2-fusion" cluster, consisting of SRMS and ERMS. CONCLUSIONS: Biopathology findings from this study support the different prognosis of infantile RMS. New fusion-positive SRMS has a very good outcome which may allow more conservative treatment in the future.

Cost-Effectiveness of Drug-Eluting Stents in Elderly Patients With Coronary Artery Disease: The SENIOR Trial.

BACKGROUND: Elderly patients receive bare metal stents instead of drug-eluting stents (DES) to shorten the duration of dual antiplatelet therapy (DAPT). The SENIOR trial compared outcomes between these 2 types of stents combined with a short duration of DAPT. A significant decrease in the number of patients with at least 1 major adverse cardiac and cerebrovascular event (MACCE) was noted in the DES group. OBJECTIVES: The objective of this article was to perform an economic evaluation of the SENIOR trial. METHODS: This evaluation was performed separately in 5 participating countries using pooled patient-level data from all study patients and country-specific unit costs and utility values. Costs, MACCEs, and quality-adjusted life-years (QALYs) were calculated in both arms at 1 year, and an incremental cost-effectiveness ratio was estimated. Uncertainty was explored by probabilistic bootstrapping. RESULTS: A total of 1200 patients underwent randomization. The average total cost per patient was higher in the DES group. The number of MACCEs and average QALYs were not statistically different between the 2 groups. The 1-year incremental cost-effectiveness ratio for each country of reference ranged from €13 752 to €20 511/MACCE avoided and from €42 835 to €68 231/QALY gained. The scatter plots found a wide dispersion, reflecting a large uncertainty surrounding the results. But in each country studied, 90% of the bootstrap replications indicated a higher cost for greater effectiveness for the DES group. Assuming a willingness to pay of €50 000/QALY, there was between a 40% and 50% chance that the use of DES was cost-effective in 4 countries. CONCLUSION: The use of DES instead of bare metal stents combined with a short duration of DAPT in elderly patients induced higher cost for greater effectiveness in each of the 5 countries studied.

Cost-effectiveness of acupuncture versus standard care for pelvic and low back pain in pregnancy: A randomized controlled trial.

OBJECTIVE: To assess the cost-effectiveness of acupuncture for pelvic girdle and low back pain (PGLBP) during pregnancy. DESIGN: Pragmatic-open-label randomised controlled trial. SETTING: Five maternity hospitals. POPULATION: Pregnant women with PGLBP. METHOD: 1:1 randomization to standard care or standard care plus acupuncture (5 sessions by an acupuncturist midwife). MAIN OUTCOME MEASURE: Efficacy: proportion of days with self-assessed pain by numerical rating scale (NRS) ≤ 4/10. Cost effectiveness (societal viewpoint, time horizon: pregnancy): incremental cost per days with NRS ≤ 4/10. Indirect non-healthcare costs included daily compensations for sick leave and productivity loss caused by absenteeism or presenteeism. RESULTS: 96 women were allocated to acupuncture and 103 to standard care (total 199). The proportion of days with NRS ≤ 4/10 was greater in the acupuncture group than in the standard care group (61% vs 48%, p = 0.007). The mean Oswestry disability score was lower in the acupuncture group than with standard care alone (33 versus 38, Δ = 5, 95% CI: 0.8 to 9, p = 0.02). Average total costs were higher in the control group (€2947) than in the acupuncture group (€2635, Δ = -€312, 95% CI: -966 to +325), resulting from the higher indirect costs of absenteeism and presenteeism. Acupuncture was a dominant strategy when both healthcare and non-healthcare costs were included. Costs for the health system (employer and out-of-pocket costs excluded) were slightly higher for acupuncture (€1512 versus €1452, Δ = €60, 95% CI: -272 to +470). CONCLUSION: Acupuncture was a dominant strategy when accounting for employer costs. A 100% probability of cost-effectiveness was obtained for a willingness to pay of €100 per days with pain NRS ≤ 4.

Polymer-Free Drug-Coated Coronary Stents Are Cost-Effective in Patients at High Bleeding Risk: Economic Evaluation of the LEADERS FREE Trial.

AIMS: In patients at high risk of bleeding who undergo PCI the biolimus A9 polymer-free drug coated stent (DCS) has superior efficacy and safety compared to a bare metal stent (BMS). We estimated the cost effectiveness of DCS vs. BMS. METHODS AND RESULTS: The Leaders FREE-based economic evaluation estimated service use and quality of life data collected prospectively. The entire trial population was analysed using cost-weights from England, France, Germany, Italy, Scotland and Spain. Country-specific QALYs were derived from EQ-5D scores. We estimated cost per event averted and per QALY gained. DCS use resulted in -0.095 cardiac deaths, target vessel MI, stent thrombosis and revascularization per patient (0.152 vs. 0.237;p<0.001). One-year QALYs were non-significantly higher in the DCS group. Total costs for the index admission were similar between groups. One-year costs using cost-weights from each of the 6 countries, including the additional €300 per DCS stent, ranged from €4,664-8,593 for DCS and €4,845-9,742 for BMS and were lower in the DCS group (England:€-428, France:€-137, Germany:€-33, Italy:€-522, Scotland:€-298, Spain:€-854). CONCLUSIONS: The probability that DCS dominated BMS was >50% in all countries. At a threshold of €10,000 per event averted DCS had a 98% probability of being cost-effective in all 6 countries.
