[Medico-economic evaluation of the PRADO-BPCO post-exacerbation support program]. / Évaluation médicoéconomique du PRADO-BPCO, programme d'accompagnement post-exacerbation.

INTRODUCTION: The "Programme d'Accompagnement du retour à Domicile" (PRADO) COPD is a home discharge support program dedicated to organizing care pathways following hospitalization for COPD exacerbation. This study aimed at assessing its medico-economic impact. METHODS: This was a retrospective database study of patients included in the PRADO BPCO between 2017 and 2019. Data were extracted from the National Health Data System. A control group was built using propensity score matching. Morbi-mortality and costs (national health insurance perspective) were measured during the year following hospitalization. RESULTS: While the proportion of patients with a care pathway complying with recommendations from the National Health Authority was higher in the PRADO group, there was no significant effect on mortality and 12-month rehospitalization. In the PRADO group, the rehospitalization rate was lower when the care pathway was optimal. Healthcare costs per patient were 670 € higher in the PRADO group. CONCLUSIONS: The PRADO COPD improves quality of care but without decreasing rehospitalizations and mortality, although rehospitalizations did decrease among PRADO group patients benefiting from an optimal care pathway.

Prevalence and management of chronic breathlessness in COPD in a tertiary care center.

BACKGROUND: Breathlessness is the prominent symptom of chronic obstructive pulmonary disease (COPD). Despite optimal therapeutic management including pharmacological and non-pharmacological interventions, many COPD patients exhibit significant breathlessness. Chronic breathlessness is defined as breathlessness that persists despite optimal treatment of the underlying disease. Because of the major disability related to chronic breathlessness, symptomatic treatments including opioids have been recommended by several authors. The prevalence of chronic breathlessness in COPD and its management in routine clinical practice have been poorly investigated. Our aim was to examine prevalence, associated characteristics and management of chronic breathlessness in patients with COPD recruited in a real-life tertiary hospital-based cohort. METHODS: A prospective study was conducted among 120 consecutive COPD patients recruited, in stable condition, at Nancy University Hospital, France. In parallel, 88 pulmonologists of the same geographical region were asked to respond to an on-line questionnaire on breathlessness management. RESULTS: Sixty four (53%) patients had severe breathlessness (modified Medical Research Council scale≥3), despite optimal inhaled medications for 94% of them; 40% had undergone pulmonary rehabilitation within the past 2 years. The severity of breathlessness increased with increasing airflow limitation. Breathlessness was associated with increased symptoms of anxiety, depression and with osteoporosis. No relation was found with other symptoms, exacerbation rate, or cardiovascular comorbidities. Among the patients with chronic breathlessness and Hospitalized Anxiety and/or Depression score > 10, only 25% were treated with antidepressant or anxiolytic. Among the pulmonologists 46 (52%) answered to the questionnaire and expressed a high willingness to prescribe opioids forchronic breathlessness, which contrasted with the finding that none of these patients received such treatments against breathlessness. CONCLUSION: Treatment approaches to breathlessness and associated psychological distress are insufficient in COPD. This study highlights underuse of pulmonary rehabilitation and symptomatic treatment for breathlessness.

Guidance to 2018 good practice: ARIA digitally-enabled, integrated, person-centred care for rhinitis and asthma.

AIMS: Mobile Airways Sentinel NetworK (MASK) belongs to the Fondation Partenariale MACVIA-LR of Montpellier, France and aims to provide an active and healthy life to rhinitis sufferers and to those with asthma multimorbidity across the life cycle, whatever their gender or socio-economic status, in order to reduce health and social inequities incurred by the disease and to improve the digital transformation of health and care. The ultimate goal is to change the management strategy in chronic diseases. METHODS: MASK implements ICT technologies for individualized and predictive medicine to develop novel care pathways by a multi-disciplinary group centred around the patients. STAKEHOLDERS: Include patients, health care professionals (pharmacists and physicians), authorities, patient's associations, private and public sectors. RESULTS: MASK is deployed in 23 countries and 17 languages. 26,000 users have registered. EU GRANTS 2018: MASK is participating in EU projects (POLLAR: impact of air POLLution in Asthma and Rhinitis, EIT Health, DigitalHealthEurope, Euriphi and Vigour). LESSONS LEARNT: (i) Adherence to treatment is the major problem of allergic disease, (ii) Self-management strategies should be considerably expanded (behavioural), (iii) Change management is essential in allergic diseases, (iv) Education strategies should be reconsidered using a patient-centred approach and (v) Lessons learnt for allergic diseases can be expanded to chronic diseases.

Contribution of exhaled nitric oxide measurement in airway inflammation assessment in asthma. A position paper from the French Speaking Respiratory Society.

Nitric oxide (NO) is both a gas and a ubiquitous inter- and intracellular messenger with numerous physiological functions. As its synthesis is markedly increased during inflammatory processes, NO can be used as a surrogate marker of acute and/or chronic inflammation. It is possible to quantify fractional concentration of NO in exhaled breath (FENO) to detect airway inflammation, and thus improve the diagnosis of asthma by better characterizing asthmatic patients with eosinophilic bronchial inflammation, and eventually improve the management of targeted asthmatic patients. FENO measurement can therefore be viewed as a new, reproducible and easy to perform pulmonary function test. Measuring FENO is the only non-invasive pulmonary function test allowing (1) detecting, (2) quantifying and (3) monitoring changes in inflammatory processes during the course of various respiratory disorders, including corticosensitive asthma.

[Management and costs of chronic pulmonary obstructive disease in France in 2011]. / Prise en charge et coûts de la bronchopneumopathie chronique obstructive en France en 2011.

OBJECTIVES: To estimate the prevalence of treated chronic obstructive pulmonary disease (COPD) and its associated costs by stage of severity. METHODS: The study was conducted on the 2011 data of the french general beneficiary sample database (EGB). EGB is a 1/97th sample of the whole population of the beneficiaries of the main compulsory national health insurances. COPD cases and the level of severity of the disease have been identified using new algorithms established from the available parameters in EGB. Costs were estimated using a collective perspective. RESULTS: The minimal prevalence of treated COPD was estimated at 3.8% in patients of 40 years and older and 1.9% regardless of the age of individuals. This population was predominantly male (58.2%) with a mean age of 68.8 years (±12.7). A total of 6.2% of patients had a health-care utilization suggestive of a very severe stage of COPD and 8.1%, 13.8% and 71.9% suggestive of severe, moderate and mild stages respectively. Over one year, 28.8% of patients visited a specialist respiratory physician, 5.0% were hospitalized (≥24h) for COPD and 6.7% died. Patients experienced an average of 1.7 (±1.5) exacerbations per year and only 61.4% received specific pharmacological treatment for COPD during the year. The average yearly health-care cost of a patient with COPD was estimated at €9382, with €5342 directly related to COPD. CONCLUSION: This study based on medico-administrative databases confirms the high epidemiological and economic burden of COPD in France.

[Epidemiology and COPD screening in France. Workshop from the Société de Pneumologie de Langue Française (SPLF)]. / Épidémiologie et dépistage de la BPCO en France. Workshop de la Société de pneumologie de langue française (SPLF).

INTRODUCTION: A workshop has been organized in April 2013 by the Société de Pneumologie de Langue Française about COPD epidemiology and COPD screening in France and other European countries. This article deals with epidemiological data and their consequences on the French screening strategy. STATE-OF-THE-ART: According to the most recent data, spirometric prevalence of COPD in France is 7.5% in individuals over 45 years old. During 2000-2002, COPD was responsible for 1.4% of all causes of death in France and was mentioned to be an associated cause of death in 3% of all death certificates. The average medical costs for one COPD patient is estimated to be 4366 €/year, until 7502 €/year in very severe COPD patients. All clinical studies that have been performed in France show that COPD screening via mini-spirometry is feasible in general practice or in an ambulatory setting; however, a mass screening proved to be difficult to perform. A simple technique like the Piko-6(®) implies a concomitant formalized training. The non-reimbursement by the French Social Security is also a limiting factor, as the absence of medical and economical validation of this strategy. Therefore, COPD screening should be focused to individuals at risk and should include tobacco issues and cessation. CONCLUSION: COPD screening strategies have to be medically evaluated and experiments have to take the specificities of the French health organization into consideration. Any COPD screening strategy should be considered as an overall fight against the tobacco epidemics.

[Long-term oxygen therapy in France, 2006-2011]. / Oxygénothérapie de longue durée en France, 2006-2011.

OBJECTIVE: The study aimed to describe the main characteristics of people treated with long-term oxygen therapy (LTOT) and the trends between 2006 and 2011 for prevalence and incidence. METHODS: Data were provided from a sample comprising 1/97 of the permanent beneficiaries of the French health insurance. The sample contains anonymous socio-demographic characteristics and data on health care reimbursements. The analyses were carried out among adults aged 20 years and above who had received benefits on account of LTOT. RESULTS: In 2011, 2.6% of adults were treated with LTOT, corresponding to around 135,000 people. The crude incidence rate was 0.9‰. The prescription of LTOT included LTOT alone (70%), LTOT associated with assisted ventilation (23%) and LTOT associated with continuous positive airway pressure (7%). About 45% of the patients were supported financially in the long-term illness program of the French Social Security because of severe chronic respiratory failure. Between 2006 and 2011, the age-adjusted prevalence rates increased by 2.9% per year in men and by 6.7% per year in women. The age-adjusted incidence rates remained stable in men (+1.6% per year, P=0.45) but increased in women (+4.7% per year, P=0.04). The median survival was 27 months. CONCLUSION: This analysis of the data demonstrates an increasing burden associated with LTOT in France from 2006 to 2011.

Isokinetic assessment of the effects of botulinum toxin injection on spasticity and voluntary strength in patients with spastic hemiparesis.

BACKGROUND: Peak knee flexion during swing phase is frequently reduced following stroke. The main treatment is botulinum toxin injection (BoNT-A) of the Rectus Femoris (RF) muscle. BoNT-A injections have been shown to decrease spasticity (assessed using the modified Ashworth scale) and to improve peak knee flexion during swing phase. Although the effect of BoNT-A has been clearly demonstrated on kinematic parameters during gait, the direct effects on spasticity and strength have been little studied using objective and sensitive outcome measures. AIM: The aim of this study was to use an isokinetic dynamometer to assess the effects of BoNT-A injection in the RF on stretch reflex-related torque at the knee joint and peak voluntary knee flexor and extensor torque and to evaluate the effect on functional capacity. DESIGN: Before-after trial: Assessments were carried out pre and post (four weeks) RF BoNT-A injection. Clinical and isokinetic evaluations were carried out. SETTING: Ambulatory care in a hospital setting. Participants. Population-based sample of fourteen chronic spastic hemiparetic patients with stiff knee gait. METHODS: Primary outcome measurements were stretch reflex-related torque at the knee joint and peak voluntary knee flexor and extensor torque. Secondary outcomes were knee angle at peak torque, the slope of the torque velocity curve, stiffness and functional outcomes. RESULTS: Peak knee extensor torque was significantly decreased and peak knee flexor torque was significantly increased during maximal voluntary concentric and isometric contractions following BoNT-A injection of the RF. Stretch reflex-related torque evaluated during passive stretching movements was reduced and the angle of occurrence of the peak was greater. Functional outcomes did not change. CONCLUSIONS AND CLINICAL REHABILITATION IMPACT: The results of this study indicate that BoNT-A injection reduced RF spasticity but also reduced quadriceps strength. In contrast, knee flexor strength increased. These changes did not, however, lead to functional gait changes.

Retail sales of inhalation devices in European countries: so much for a global policy.

OBJECTIVE: To evaluate the retail sales of pressurised metered-dose inhalers (pMDIs), dry-powder inhalers (DPIs) and liquids for nebulisation in 16 European countries. METHODS: Retail sales data relating to pMDIs, DPIs and liquids for nebulisation delivering short- and long-acting bronchodilators, corticosteroids and combinations between 2002 and 2008 were obtained from the IMS sales database. The IMS database ensured that wholesalers' stock sales accurately matched that of retail pharmacies and included purchases by panel pharmacies directly from pharmaceutical manufacturers, specialist wholesalers and distribution cooperatives. RESULTS: Mean inhaler retail sales (expressed as percentages of total sales) were 47.5% for pMDIs, 39.5% for DPIs and 13% for nebulisers. The distribution of inhaler sales differed significantly between the countries with pMDI sales greatest in the United Kingdom and Hungary compared to other countries, where DPI sales prevailed. Sales of nebulisation liquids were high in Italy. The pMDI was the most frequently prescribed inhaler for bronchodilators. In contrast, retail sales of DPIs were similar to those of pMDIs for inhaled corticosteroids, and higher in the case of inhalers with combined long-acting ß(2)-agonist and corticosteroid. CONCLUSION: We found a high degree of variability in inhaler prescription between European countries. Differing health policies, costs, health insurance issues, pharmaceutical/commercial aspects and prescribers' and patients' preferences may explain this variation. We suggest a need for more uniform, outcome-led inhaler prescribing practice across Europe to improve the efficacy and cost effectiveness of the treatment of obstructive airways diseases.

Comparison of the repercussions of cLBP in four French-speaking countries.

INTRODUCTION: Sociocultural factors may influence the impact of chronic low back pain (cLBP) on patients. The goal of this study was to compare pain and disability levels, and psychobehavioural parameters in four French-speaking countries in patients with cLBP. METHODS: Two hundred and seventy-eight patients were included: 83 in France, 36 in Morocco, 75 in the Ivory Coast and 84 in Tunisia. Demographic data were collected; pain was assessed using a visual analogue scale (VAS), disability with the Quebec scale, psychobehavioural factors by the hospital anxiety depression scale (HAD), the fear and avoidance beliefs questionnaire (FABQ) and the coping strategy questionnaire (CSQ). A Student t-test was used to compare means. Anova (covariance) was used to test for a "Country Effect", i.e. the incidence of country on outcomes. OUTCOMES: There was no difference in disability levels between countries. A "country effect" was found (p<0.001) for pain (F=2.707), anxiety (F=3.467), depression (F=5.137), fear and avoidance beliefs regarding professional activity (F=1.974) and physical activity (F=5.076), strategy of distraction, dramatization, efforts to ignore pain, prayer, seeking social support and reinterpretation (p<0.01). Pain level was higher in Morocco (p<0.05); anxiety, depression, fear and avoidance beliefs about physical activities were higher in Tunisia (p<0.05) and fear and avoidance beliefs about professional activities were higher in the Ivory Coast (p<0.01). Among the coping strategies used, distraction, dramatization, prayer and search for social support were used more in the Ivory Coast; reinterpretation in Tunisia; seeking social support was less common in France. CONCLUSION: In this population of patients with cLBP, despite similar disability levels across the four French-speaking countries, there were considerable variations in pain level and psychobehavioural repercussions.

[Management of increase in spasticity in patients with intrathecal baclofen pumps]. / Conduite à tenir devant une recrudescence de spasticité chez un patient porteur d'une pompe à baclofène.

INTRODUCTION: The incidence of complications after baclofen pump implantation is relatively high. Diagnosis of these complications can be difficult. A diagnostic tree would be a useful tool in cases of suspected malfunctioning of the intrathecal bacolfen infusion system and would standardise the diagnostic procedure. METHOD: From results in the literature and the experience of our department, we designed a diagnostic tree to aid in finding the cause of a recrudescence of spasticity in patients with implanted baclofen pumps. RESULTS: The potential causes of recrudescence of spasticity are described and a diagnostic pathway is proposed. DISCUSSION: The aim of a standardised hierarchical method of diagnosis of the cause of increased spasticity in patients with intrathecal baclofen pumps is to gain time in the diagnosis and treatment. Such diagnosis should improve patient care by permitting rapid restoration of an adequate level of baclofen infusion as well as decreasing the length of hospital stay and, as a consequence, the cost relating to malfunctioning pumps.

Misuse of corticosteroid metered-dose inhaler is associated with decreased asthma stability.

This study assessed whether the improper use of pressurized metered-dose inhalers (pMDIs) is associated with decreased asthma control in asthmatics treated by inhaled corticosteroids (ICS). General practitioners (GPs) included consecutive asthmatic outpatients treated by pMDI-administered ICS and on-demand, short-acting beta2-agonists. They measured an asthma instability score (AIS) based on daytime and nocturnal symptoms, exercise-induced dyspnoea, beta2-agonist usage, emergency-care visits and global perception of asthma control within the preceding month; the inhalation technique of the patient also was assessed. GPs (n=915) included 4,078 adult asthmatics; 3,955 questionnaires were evaluable. pMDI was misused by 71% of patients, of which 47% was due to poor coordination. Asthma was less stable in pMDI misusers than in good users (AIS: 3.93 versus 2.86, p<0.001). Among misusers, asthma was less stable in poor coordinators (AIS: 4.38 versus 3.56 in good coordinators, p<0.001). To conclude, misuse of pressurized metered-dose inhalers, which is mainly due to poor coordination, is frequent and associated with poorer asthma control in inhaled corticosteroid-treated asthmatics. This study highlights the importance of evaluating inhalation technique and providing appropriate education in all patients, especially before increasing inhaled corticosteroid dosage or adding other agents. The use of devices which alleviate coordination problems should be reinforced in pressurized metered-dose inhaler misusers.
