The effect of weather and temporal factors on emergency hand trauma consultations

INTRODUCTION

Fluctuations in the numbers of patient consultations in hand trauma emergency units are challenging in terms of both scheduling and the provision of sufficient resources. Trauma consultations in general are affected by both temporal and meteorological variables. As the genesis and epidemiology of hand trauma have their own characteristics, this study aimed to identify the influence of temporal and meteorological factors on hand trauma consultations.

MATERIALS AND METHODS

All patients treated for hand trauma in our level one trauma center in 2019 were included in the study population and the data were analyzed in retrospect. The daily weather data, including temperature, sunshine duration, precipitation, humidity and wind speed, as well as temporal factors such as time of day, weekday and public holidays were considered and correlated with patient consultations. Gender differences were studied as well.

RESULTS

We included 4787 hand trauma patients (66.4% male, mean age 38.4 ± 19.3 years, 31.7% occupational injuries). Significantly more consultations occurred on Saturdays as compared to weekdays (14.8 ± 0.6, n = 52 vs. 13.0 ± 0.2, n = 261; p = 0.028), and fewer occurred on official holidays (11.8 ± 0.5, n = 63 vs. 13.4 ± 0.2, n = 302; p = 0.0047). We found a significant positive correlation between daily consultations, sunshine duration (r = 0.14, p = 0.0056) and the mean temperature (r = 0.20, p < 0.0001); in contrast, a significant negative correlation between daily consultations and humidity (r = - 0.17, p = 0.001) was observed. Furthermore, fewer consultations were seen on days with precipitation (12.7 ± 0.3, n = 219 vs. 13.8 ± 0.3, n = 146; p = 0.009). The variation was considerably stronger in men.

CONCLUSIONS

Hand trauma consultations increased with increasing temperatures, duration of sunshine, and decreasing humidity. Peak admissions were seen on Fridays and Saturdays. These findings can assist in predicting days with peak admissions to allocate resources appropriately.

[The Emergency Classification of Hand Injuries: Analyzing Urgency Assessment among German Hand Surgeons]

BACKGROUND

Emergency capacities in the operating theatre are limited and often need to be split among surgical departments. Hand injuries often have to compete with other surgical disciplines for the availability of operating capacity. For this reason, an emergency classification was introduced to define a timespan in which the injury should be taken care of in the OR in order to enable the prioritizing of emergency cases in an interdisciplinary approach when capacities are scarce. However, neither valid data nor specific recommendations concerning the medical urgency of treatment or the forensic background of different hand injuries exist to this date.

PURPOSE

This work describes how emergency classifications in Germany are applied to hand surgical cases and how certain hand injuries are prioritized among different hand surgeons.

MATERIAL AND METHODS

An online survey was sent to all members of the German Society for Hand Surgery twice during a time span of several months. The survey featured questions on size and type of clinic or practice and requested an assessment of urgency levels for various hand injuries (immediately - within 2 h - within 6 h - within 12 h - within 24 h or elective care). The analysis of the questionnaire and graphic presentation was carried out using Excel.

RESULTS

172 (25 %) out of 700 active members filled in the survey. Among the participants were members of university clinics, hospitals run by the German Statutory Accident Insurance, specialized clinics and primary care clinics. 15 % of participants work in a practice that offers hand-surgical treatment. First and foremost, maximum care hospitals with a hand surgical department participate in the treatment of hand injuries. 64 % of the hospitals use an emergency classification to enable the interdisciplinary prioritizing of surgical emergencies. The categorization of limb-threatening hand injuries appears to be very homogenous among participants whereas non-threatening injuries are assessed rather inconsistently.

CONCLUSION

Emergency treatment of hand injuries primarily depends on available resources and surgical capacities. The assessment of urgency and severity of injuries additionally depends on experience and education. In order to maintain the ability to compete with other surgical disciplines for surgical capacities, a standard classification of hand surgical urgencies needs to be established. As valid data on the treatment of hand injuries are still missing, further studies need to evaluate possible outcomes in order to define the timespan in which surgery should take place.
