The characteristics of patient presentations from Australian outdoor music festival

  1. 1. Understanding the characteristics of patientpresentations at outdoor music festivalsAssociate Professor Alison HuttonMr Jamie RanseProfessor Paul Arbon
  2. 2. Aim of the study• To understand thecharacteristics ofpeople who present aspatients to on-sitehealth care at outdoormusic festivals inAustralia• Determine the relativeproportion and type ofinjury
  3. 3. Design and Setting• Retrospective review of patient report forms• 26 OMF• Four different states of Australia• Data transcribed to Excel• Ranse and Hutton minimum data set;– Illness;– Injury;– Environmental;– Mental Health
  4. 4. Data analysis• Proportions were presented as percentages• Variations in proportions Fisher exact test• Binary logistic regression model• Adjusted for potential clustering effects becausePPs was heterogeneous for different events• Regression coefficients were expressed asadjusted odds ratios (OR)• OR were considered statistically significant iftheir 95% confidence interval (CI) did not includeunity
  5. 5. Demographics• 4950 presentations for health care, almosttwo thirds were female (n=3087, 62.4%)• The mean age (±SD) of all patientpresentations was 21.3 (±5.8) years• The majority of patients (n=3875, 78.3%)were ≤25 years of age
  6. 6. Illness• The majority of patient presentations (n=2766,55.9%) presented with illness related concerns• The risk of illness was 1.7 times (OR=1.71; 95%CI 1.51-1.94; p<0.001) higher for females thanmales in the ≤25 year age group• Most common presenting problem washeadache (n=1389, 52.9%).• Pain (n=264 10%), asthma (n=216 8.2%), andnausea and vomiting (n=211 8%)
  7. 7. Injury• The risk of a female sustaining an injury was almost half(OR=0.54; 95% CI 0.47-0.62; p<0.001) that of males• Age was not a significant factor in predicting injury• The main types of injury presentations were superficiallacerations (n=281; 20.4%); sprain or strains (n=268;19.2%), and head injuries (concussion) (n=168; 11.9%)• Lower proportion of females presenting with dislocationsand superficial lacerations than males• Crushing injuries; blisters and foreign bodies; external toeye was significantly higher for females than males
  8. 8. Environment• Lower for patient presentations aged >25 years (OR=0.55;95% CI 0.41-0.72; p<0.001)• Alcohol related presentations most common(n=250 32.8%)• Substance related (n=135 17.7%),• Combined alcohol and substance use (n=125 16.4%)• Both heat exhaustion and substance use were statisticallysignificant when compared to gender• Heat exhaustion more prevalent for females (p=<0.001),while substance related presentations more prevalent formales (p=<0.001)
  9. 9. Mental Health• Gender didn’t demonstrate a significantrisk for mental health relatedpresentations• 29 cases overall – average of one perevent• MH recorded as a presentationsignifigant
  10. 10. Outcome• Most patient presentations assessed by medicalteams; treated and returned back to the event(n=2421; 48.9%)• Environmental-related category highest transport tohospital rate– 9.1% (n=71) being referred to hospital– 12.5% (n=97) referred to a doctor and– 17.0% (n=132) were discharged home
  11. 11. Implications for Practice• Previous findings confirmed• Illness category – presenting signs andsymptoms dominate• Improved understanding of diagnosis needed• Further scope for preventable presentations,such as headaches• Increased understanding of injury leads toeffective prevention strategies
  12. 12. Conclusions• Large number of drug and alcoholpresentations transferred to hospital• Many minor illness and injuriespreventable• Increased focus on preventionstrategies required• Need a more accurate picture ofaudience demographic
