Objective: To assess the use of a standardized evaluation algorithm [American College of Chest Physician (ACCP) 2006] in children with chronic cough.
Methods: In this prospective cohort study, children with chronic cough were evaluated as per the ACCP 2006 diagnostic algorithm. All children were followed regularly at an interval of 2-4 wk. The study's endpoint was for the patient being cough free for four weeks either following treatment or naturally.
Results: The mean age of the 87 studied children (52 male, 35 female) was 11.9±3 y. Forty children (45.9%) had specific cough pointers on history and examination. Radiograph showed abnormalities in 12 (13.8%) children, and spirometry showed a reversible obstructive pattern on spirometry in 6 (6.9%) among 47 (54%) children without specific cough pointers. After a detailed evaluation, 16 (18.3%) children had no remarkable findings and were reviewed after two weeks. Spontaneous resolution of cough occurred in 6 children. A trial of inhalational corticosteroids (ICS) (9 children) or antibiotics (1 child) was given to the rest of the ten children. Specific underlying diagnoses could be established in 80 (91.9%) children. The most common etiology identified in the study was asthma and asthma-like illnesses (n = 52; 59.8%), followed by upper airway cough syndrome (n = 13; 14.9%) and tuberculosis (n = 9; 10.4%). Eighty-four (96.5%) children had complete resolution of cough during follow-up. The mean time to resolution in the study was 33.6±16.8 d.
Conclusions: This study demonstrated that the ACCP 2006 algorithm is effective in establishing the underlying etiology and managing children with chronic cough.
