Dyspnea: assessment and treatment.

Abstract

Dyspnea, or breathlessness, is a very distressing and prevalent symptom for patients with terminal cancer. Assessment for this symptom is generally poorly conducted, and it is therefore frequently underdiagnosed and inadequately treated. This paper outlines several tools found in the literature that may be beneficial to us in assessing this symptom. There will also be a full report on the application of these scales as used in a hospital audit of all in-patients at the Queensway- Carleton Hospital in Nepean, Ontario, during the month of June 1995. Results of this hospital audit revealed that 33% of all patients in hospital complained of some degree of breathlessness on both the Linear Analogue Scale Assessment and the Borg Scale. However, when the Modified Medical Research Council Dyspnea Scale and the Oxygen Cost Diagram Scale were used 75.6% and 78.5% respectively now complained of significant shortness of breath interfering with their quality of life. We also found that patients experiencing dyspnea were 39% more likely to complain of other symptoms than patients with no shortness of breath and were 55% more likely to report other symptoms as being severe. A short section will also outline the medical and nursing management of dyspnea and will include a discussion of possibly correcting the cause of breathlessness, environmental issues, and pharmacological management of dyspnea. It is advocated that during the terminal stages of a patient's illness, when assessment tools are no longer feasible or possible, that a "breathing comfortably" approach be adopted for patient and family comfort.
