[Targeted screening of COPD in primary care: Feasibility and effectiveness]. / Détection précoce de la BPCO en soins primaires : un essai contrôlé randomisé.

INTRODUCTION: Chronic obstructive pulmonary disease (COPD) is a common but under-diagnosed pathology in primary care. The objective was to study the feasibility of a randomized controlled trial in general practice to detect new cases of COPD at an earlier stage. METHODS: A cluster randomized, controlled, multicenter intervention study comparing, according to a 2×2 factorial plan, two case finding strategies: a systematic GOLD-HAS hetero-questionnaire and coordination of the patient's path to facilitate access to spirometry. The PIL-DISCO pilot study took place in 2017. Patients between 40 and 80 years old, with no previous history of COPD, consulting their GP on a given day regardless of the reason, were included. RESULTS: 176 patients were included in 1.5 days. Spirometry was performed in none of the control arm, in 13 (29.5%) of the questionnaire arm, in 22 (50%) in the coordination arm and in 32 (72.7%) with the combination of the two strategies. Two cases of stage 2 COPD and thirteen other respiratory diseases were diagnosed. CONCLUSIONS: This study confirms the feasibility of the protocol in primary care in terms of speed of inclusion and acceptability. An extension phase aiming to include 3200 patients will assess the diagnostic value of the two strategies tested in general practice.

Case-control study found that primary language disorders were associated with screen exposure.

AIM: We explored the associations between childhood exposure to screens, including televisions, computers, game consoles, tablets and smartphones and primary language disorders. METHODS: This multi-centre case-control study comprised 167 children aged 3.5-6.5 years, who were born in 2010-2012 and diagnosed with primary language disorders, and 109 matched controls without language disorders. Questionnaires were completed by their parents who were recruited by 16 family doctors and 27 speech and language therapists in the Ille-et-Vilaine region of France. The data were analysed using a multivariate logistic regression model and presented as adjusted odds ratios (aOR) and 95% confidence intervals (95% CI). RESULTS: We found that cases (44.3%) and controls (22.0%) exposed to screens in the morning before nursery or primary school were three times more likely to develop primary language disorders (aOR 3.40, 95% CI 1.60-7.23). When this risk was combined with rarely or never discussing screen content with their parents (aOR 2.14, 95% CI 1.01-4.54) they were six times more likely to have language problems (aOR 5.86, 95% CI 1.44-23.95). CONCLUSION: Being exposed to screens in the morning before school, and rarely or never discussing screen content with parents, meant children were six times more likely to develop primary language disorders.
