METHODS: This study took place at Eastern Visayas Regional Medical Center (EVRMC) in Tacloban, and Ormoc District Hospital (ODH) in Ormoc. We determined whether there were differences in the pattern of admissions between the week before and the three weeks after Haiyan by using information on sex, age, diagnosis, ward and outcome at discharge from patient records. RESULTS: There was a drop in admissions in both hospitals after Haiyan as compared to before. Admissions climbed back to the baseline after ten days in EVRMC and after two weeks in ODH. When comparing the period after Haiyan to the period before, there was a relative increase in male versus female admissions in ODH (OR 2.8, 95%CI 1.7-4.3), but not in EVRMC. Patients aged >/=50 years and 0-14 years had the highest relative increase in admissions. There was a relative decrease in admissions for the ICD10 group 'Pregnancy, childbirth and the puerperium' (OR 0.4, 95%CI 0.3-0.6), and an increase in 'Certain infectious and parasitic diseases' (OR 2.1, 95%CI 1.2-3.5), mainly gastroenteritis, and 'Diseases of the respiratory system' (OR 1.8, 95%CI 1.0-3.0), mainly pneumonia, compared to all other diagnosis groups in ODH. Out of all reasons for admission within the study period, 66% belong to these three ICD-10 groups. Data on reasons for admission were not available for EVRMC. CONCLUSIONS: The observed reduction in patients after the Typhoon calls for ensuring that hospital accessibility should be protected and reinforced, especially for pregnant women, by trying to remove debris in the direct hospital vicinity. Hospitals in areas prone to tropical cyclones should be prepared to treat large numbers of patients with gastroenteritis and pneumonia, as part of their disaster plans
