Abstract:
A study was conducted to determine the clinical factors that affect the quality of life in adult asthmatics. As part of their routine follow-up visit, 399 patients completed the SF-36 quality of life questionnaire, had peak expiratory flow rate readings (PEFR) taken and were interviewed to determine current symptom severity. The grade of severity of asthma was verified by the consultant physician in-charge. The mean age of the patients was 41.8 years and 31.8% of the patients were men. Most of the patients were Malay (64.7%), 89% had at least secondary level education and the mean duration of asthma was 17.6 years. The majority of patients had moderate or severe disease (43.6% and 55.9% respectively). For asthmatics with moderate or severe symptoms of chest tightness and/or shortness of breath, all domains of SF-36 scored significantly lower than those with mild symptoms, with the exception of the domain bodily pain. Patients with moderate/severe cough recorded significantly lower scores than those with mild cough for all domains except for bodily pain and social functioning. Only the physical functioning, role physical, general health and role emotional scores were significantly worse in those with a consultant grade of severe asthma compared to those with mild/moderate asthma. Patients with PEFR < 80% predicted had lower scores for the domains physical functioning, role physical and general health than those with PEFR > or = 80% predicted, but the scores for the other domains were similar in both groups. Quality of life is significantly impaired in adult asthmatics with current respiratory symptoms. However, consultant grade of severity of asthma and PEFR readings do not affect quality of life scores as much.
