La bronchopneumopathie chronique obstructive (BPCO) du sujet âgé en huit questions/réponses

Chronic obstructive pulmonary disease (COPD) is a chronic disease characterized by incompletely reversible airflow limitation, measured by a decrease of FEV1/FVC ratio. International consensus does not agree on a single threshold for this ratio, which can define airflow obstruction. Although the prevalence of COPD in the elderly population varies according to the definition used, it definitely increases with age and could reach 15 % in those over 65 years of age. Therefore, ageing of the population should result in increased prevalence and socioeconomical costs of COPD during coming years. In France, diagnosis of COPD in the elderly is difficult, late and insufficient. Management, which has the same goals as in younger populations, has to be global and coordinated. Some points should be considered with particular attention considering the cumulative risks related on the one hand to COPD and on the other to ageing: pharmacological side-effects, decreased physical and social autonomy, nutritional impairment, comorbidities. Given the lack of specific data in elderly populations, pharmacological indications are generally considered to be the same as in younger populations, but some additional precautionary measures are necessary. Pulmonary rehabilitation seems to be beneficial at any age. Palliative care comes up against important difficulties: an indefinite beginning of the palliative stage in COPD; insufficient palliative care resources; insufficient communication; insufficient utilization of palliative care resources. Global COPD management in elderly requires coordination, best reached in health care network organizations involving medical and/or social professionals.
