Methods: • This study was conducted in 8 countries of which 5 were in the Americas (Brazil, El Salvador, Guatemala, Panama, and Venezuela) and 3 in Asia (Cambodia, Malaysia, and Thailand). • The 1695 eligible participants, recruited mostly in 2005, were consecutively or randomly selected clinical or confirmed dengue patients treated at representative, mostly public, hospitals and ambulatory facilities. • Data came from 1-2 interviews with each patient (or parent) and abstracts of medical records. • Medical utilization included numbers of both private and public ambulatory visits and inpatient days. • Results: • About half (48%) of the sample patients were aged 0-14, 55% were ambulatory participants, and 71% had dengue confirmed by laboratory tests. • Ambulatory patients averaged 4.2 visits (SD 2.7) while hospitalized patients averaged 4.6 visits (SD 2.2) before and after their hospitalization. Most of the ambulatory care was received in the public sector. • Utilization patterns varied by country. The mean number of visits ranged from 2.8 (Guatemala) to 6.3 (El Salvador) among ambulatory patients and from 2.0 (El Salvador) to 7.1 (Malaysia) among hospitalized patients. • The average length of stay for hospitalized patients was 3.8 days (SD 2.5) with country means ranging from 2.8 days (Malaysia) to 6.4 (Guatemala). • The duration of fever averaged 4.9 (SD 2.9) days among ambulatory patients and 5.9 (SD 2.8) days among hospitalized patients. • The mean total duration of illness was 11.9 (SD 6.9) days among ambulatory patients and 10.9 (SD 4.6) days among hospitalized patients. • Using the Euroqual quality of life “thermometer” (where 0 is lowest and 100 best), ambulatory patients averaged only 30 (SD 18) and hospitalized patients 33 (SD 25). • Conclusion: • Treatment patterns varied by country. On average, however, use of ambulatory visits, length of fever, duration of illness, and quality of life were almost as severe among ambulatory patients as among hospitalized patients. • Utilization of medical services is substantial and quality of life is low for both ambulatory and hospitalized dengue cases across 8 countries on two continents.
