The Effect of Hurricane Maria on the Surgical Workload of the UPR-affiliated Hospitals.

Abstract

Objective: The Caribbean islands are regularly affected by hurricanes in a seasonal manner, but major (category 4 and 5) hurricanes are infrequent, and what happens in their aftermath is important for future planning.

Methods: We reviewed the surgical cases entered into the University of Puerto Rico (UPR) General Surgery Department database from January 1, 2016, through December 31, 2017. This database collects patient and procedural information from the surgical services of the UPR-affiliated hospitals. To analyze the impact that Hurricane Maria had on the surgical population, we compared cases per month using September 2017 (the month that Maria struck Puerto Rico) as the reference month. A chi-square goodness-of-fit test was used to evaluate differences between months.

Results: Information was available for 9,059 cases during the study period. The mean age of the group was 49±14 years, the gender distribution being 56% women, 44% men. The study found a statistically significant difference (p<0.001) in the number of surgical cases per month, with fewer patients in September 2017 (n = 210) compared to other months, representing a 57% decline in the number of cases. These patients tended to be sicker, with an increase in the number who had an American Society of Anesthesiologists physical status classification of 3 or greater. Within 3 months after the natural disaster, the volume of patients started to return to normal.

Conclusion: We found that this major hurricane resulted in a decreased surgical workload, mostly because elective surgery cases were fewer, but that the patients that came for surgical care tended to be sicker and had, for the most part, poorly controlled systemic diseases. The volume of surgical cases did not reach normal levels until 3 months after the natural disaster.
