[18] Focus group interviews from three countries in Central America found that persons considered the healthcare obtained through private physicians and clinics preferable to public options because of prompt attention and a perception that healthcare is better. [19] Another study evaluating healthcare utilization among children in rural Guatemala who reported a diarrheal or respiratory illness found private physicians were more likely to be consulted by households with higher income. [20] The population that uses government health clinics and hospitals for respiratory illnesses in Santa Rosa is younger and poorer than the general population. We found a trend for decreasing use of government facilities with increasing age and household wealth. These findings should be taken into account to improve the generalizability of burden of disease estimates made from sentinel surveillance data.
