If patients are to participate fully in their care and in the management of a long-term condition such as chronic obstructive pulmonary disease, good communication is essential. However, not all patients are able to use the written word and we need to be aware of the size of this problem and its implications for the way in which we give information and conduct medical consultations. The impact of health literacy on outcomes can be considerable and improvements can be made by being aware of the problem, offering information in several different forms, and by reinforcing the spoken word with pictorial images.

ReviewEnd of life care in chronic obstructive pulmonary disease: in search of a good death.
Chronic obstructive pulmonary disease (COPD) is an incurable, progressive illness that is the fourth commonest cause of death worldwide. Death tends to occur after a prolonged functional decline associated with uncontrolled symptoms, emotional distress and social isolation. ⋯ This review provides an evidence-based approach to overcoming these barriers, summarising current evidence and highlighting areas for future research. Topics include end of life needs, symptom control, advance care planning, and service development to improve the quality of end of life care.

ReviewNoninvasive ventilation in patients with chronic obstructive airway disease.
Recent years have seen the emergence of noninvasive ventilation (NIV) as an important tool for management of patients with acute exacerbation of chronic obstructive pulmonary disease (COPD). Several well conducted studies in the recent years have established its role in the initial, as well as later management of these patients. ⋯ Moreover, data is emerging on the role of long term nocturnal NIV use in patients with very severe stable COPD. This review summarizes the evidence supporting the use of NIV in various stages of COPD, discuss the merits as well as demerits of this novel ventilatory strategy and highlight the grey areas in the current body of knowledge.

Mechanisms of improvement of respiratory failure in patients with COPD treated with NIV.
Noninvasive ventilation (NIV) improves gas-exchange and symptoms in selected chronic obstructive pulmonary disease (COPD) patients with hypercapnic respiratory failure. We hypothesized NIV reverses respiratory failure by one or all of increased ventilatory response to carbon-dioxide, reduced respiratory muscle fatigue, or improved pulmonary mechanics. ⋯ These findings suggest decreased gas trapping and increased ventilatory sensitivity to CO2 are the principal mechanism underlying improvements in gas-exchange in patients with COPD following NIV. Changes in some volitional but not nonvolitional muscle strength measures may reflect improved patient effort.

Comparative StudyNoninvasive positive pressure ventilation in acute respiratory failure due to COPD vs other causes: effectiveness and predictors of failure in a respiratory ICU in North India.
To determine the effectiveness of noninvasive positive pressure ventilation (NIPPV), and the factors predicting failure of NIPPV in acute respiratory failure (ARF) due to chronic obstructive pulmonary disease (COPD) versus other causes of ARF. ⋯ NIPPV is more effective in preventing endotracheal intubation in ARF due to COPD than other causes, and the etiology of ARF is an important predictor of NIPPV failure.
