Brief Summary:

Stingray injuries can be a hazard shared by many types of beachgoers. Stingrays often lie in the sand and when stepped on by the unsuspecting beachgoer their tail snaps foreword, resulting in a barbed stinger injecting venom into the victim. Little exists in the current literature on the natural history of stingray injuries. Most of the existing literature looks at the incidence of stings, and to a certain extent the demographic of people who seek care. To our knowledge no study has attempted to collect a more inclusive population of those people who are stung and follow them prospectively to determine the incidence of medical intervention, infection, etc.

This study aims to describe and quantify the natural history of stingray injuries and to better understand their time course and medical requirements. The study setting will be Seal Beach, which reports some of the greatest number of annual stingray injuries for any single beach on the pacific coast. Participants will be identified by the Seal Beach lifeguards who are believed to treat the majority of stingray injuries suffered at the beach. Eligible persons will be consented for participation over the phone by research personnel. If enrolled in the study they will receive a phone call by research personnel one week and one month after the injury that will collect information about the symptoms they have experienced and the medical interventions they have received, if any. This study is strictly observational in nature and will not involve any interventions on the part of study personnel or alter the manner in which or types of medical assessments or treatments.

Stingray Injury Marine Envenomation

Study Type : Observational
Actual Enrollment : 300 participants
Observational Model: Case-Only
Time Perspective: Prospective
Official Title: The Natural History of Human Stingray Injuries
Study Start Date : July 2012
Primary Completion Date : September 2016
Study Completion Date : September 2016

Group/Cohort
Enrolled participants
The targeted study population will include all people at Seal Beach who have been identified by the Seal Beach Lifeguards to have been stung by a jellyfish over the course of one year who are adults or children whose parent or guardian is present at the time of the injury. Children and pregnant women are included in the group.



Primary Outcome Measures :
  1. Incidence and duration of particular symptoms, medical evaluations, and treatment [ Time Frame: up to 30 days from the date of injury ]
    This study is descriptive in nature. The primary outcome of this study is the understanding of the natural history of stingray injuries and their treatment. This will be achieved using strictly descriptive statistics of the incidence and duration of particular symptoms, medical evaluations, and treatment. Means, proportions, and confidence intervals of these statistics will be calculated.
