Abstract

Background: Asthma is a common chronic disease with high morbidity. In Uganda, the proportion of asthma in health care facilities and the extent to which asthma management guidelines are followed is unknown.

Objectives: To determine the proportion of adult patients diagnosed with asthma and the proportion of asthma patients that receives recommended asthma therapy prescriptions according to Global Initiative for Asthma with GINA management and prevention guidelines, in the chest clinic and accident and emergency (A&E) departments in Mulago Hospital.

Methods: A retrospective chart review at Mulago Hospital chest clinic and A&E department from January 1^st 2009 to December 31^st 2009 was performed. Patients diagnosed with asthma were identified and medications prescribed were recorded. Patients were categorized as having received recommended asthma therapy prescriptions (if therapy was compatible GINA guidelines) or not. Proportions of asthmatics in the two departments and those who received recommended asthma therapy were calculated.

Results: One hundred thirty four (134) of 792 patients in the chest clinic (16.9%) were diagnosed with asthma. At the A&E four hundred and sixteen (416) patients out of 16 800 (2.5%) were diagnosed with asthma. Sixty nine point seven (69.7%)were female. The median age was 29 years  (IQR, 19-42). Wheezing was the commonest presenting symptom (55%). Recommended asthma therapy prescriptions were 47.4% for the chest clinic, and 32.2% of the patients at A&E department received asthma therapy prescriptions as recommended for asthma exacerbations management during hospitalization.

Conclusion: Asthma accounts for a significant proportion of outpatients in the chest clinic. The majority of the patients do not receive recommended asthma therapy prescriptions.
