Introduction: The belief that surgical admissions in hospitals are lower on rainy days has long been heralded as true by practicing surgeons and trainees, but seldom studied. Methods: We extracted 1 year of rainfall data for the Brisbane region from the Australian Bureau of Meteorology (BOM) and compared this against the admissions under the Plastic Surgery unit admission data from the Royal Brisbane and Women’s Hospital (RBWH). We included admissions from the emergency department or those accepted as transfers from other hospitals. We included referrals for hand injuries and non-hand injuries. The definition of a rainy day was set as any day with a rainfall measurement of >1mm in 24hrs. For each month, the average admissions for a rainy day and fair-weather day were found and compared. Results: Out of the 365 days of rainfall data, 88 days were defined as rain days. The number of admissions on rainy days was 1.54, compared to 1.99 on fair weather days. Conclusion: We confirmed the hypothesis that rainy weather is correlated with a reduction in admissions under Plastic Surgery in a Brisbane Hospital. Larger studies of this kind across multiple specialties may be valuable in predicting hospital bed pressures and lead to better resource management and staff planning.
