When your best friend bites: A note on dog and cat bites

Child safety programs for primary school children decrease the injury severity of dog bites

This study focuses on the impact of a prevention program regarding dog bites in children. As a consequence of our previous investigation in 2005, we have initiated a child safety program for primary school children starting January 2008 until present to teach children how to avoid dog attacks and how to behave in case of an attack. In our retrospective study, we analyzed all patients younger than 15 years presenting with dog-related injuries between 2014 and 2018. As the main indicator for success of the prevention measures taken, we have defined the severity of injury in comparison to our previous study. Out of 296 children with dog-related injuries, 212 (71.6%) had sustained a dog bite. In the vast majority (n = 195; 92%), these patients presented with minor injuries; the extremities were most commonly affected (n = 100; 47%). Injuries to the head (n = 95; 45%) and trunk (n = 18; 8%) were less frequent. The proportion of severe injuries (8%) was significantly lower compared to our previous study, where 26% of children presented with severe injuries necessitating surgical intervention, while the number of patients requiring in-hospital treatment declined from 27.5% in the period 1994-2003 to 9.0% in the period between 2014 and 2018 (p < 0.05).Conclusion: Teaching of primary school children may effectively reduce the injury severity of dog bites. What is Known: • Dog bites are a substantial healthcare problem especially in children. What is New: • This study shows that a broad-based prevention program for primary school children can effectively decrease the severity but not the frequency of dog bite injuries in children.

Antibiotic prescribing in patients who presented to the emergency department with dog bites: A descriptive review of current practice

OBJECTIVE

To describe the current practice of prophylactic antibiotic prescribing for patients presenting to the ED with a dog bite, and compare management against existing guidelines.

METHODS

We performed a descriptive retrospective study on all consecutive patients who presented to one tertiary teaching hospital and one regional district hospital in Southeast Queensland between 1 July 2017 and 30 June 2018 with a presentation of a dog bite. Data on demographics and management were collected from the electronic medical record using a standardised data collection tool. Risk factors supporting prophylaxis were taken from the electronic Therapeutic Guidelines.

RESULTS

Of the 336 patients included for analysis, 299 received antibiotics, of which 23 were for established infection. A total of 276 (82% of overall cohort) received a prescription for prophylactic antibiotics, either in hospital (ED or admitting ward) and/or on discharge. Of the 178 patients who received prophylactic antibiotics in hospital, 91 (51.1%) received intravenous antibiotics. Of the patients who presented to ED without a previously established infection 271 (86.6%) received prophylactic antibiotics on discharge. Over one quarter (27.5%) of patients who were given prophylactic antibiotics did not meet any high-risk factors as outlined in guidelines.

CONCLUSION

Prophylactic antibiotics are extensively used for patients with dog bites. There is scope to rationalise antibiotic use and route of antibiotic administration in patients with dog bites.

Management of bite wounds in children and adults-an analysis of over 5000 cases at a level I trauma centre

BACKGROUND

Bite wounds are among the commonest types of trauma to which man is the subject. They account for 5 % of the total traumatic wounds evaluated in the emergency department (ED) and approximately 1 % of all the ED visits. Early estimation of infection risk, adequate antibiotic therapy and if indicated surgical treatment are the cornerstones of successful cure of bite wounds.

METHODS

A total of 5248 consecutive trauma patients were collected prospectively and analysed retrospectively over a period of 15 years in this study at a level I trauma centre, Department of Trauma Surgery, Medical University of Vienna, Austria.

RESULTS

The mean age was 33.8 years (range 0-97), 2620 (49.9 %) were male and 2628 (50.1 %) were female individuals. In our study population, a total of 2530 dog bites (48.2 %), 930 cat bites (17.8 %), 357 other animal bites (6.8 %), 426 human bites (8.1 %) and 1005 human self-bites (19.2 %) have been observed. A total of 995 wounds (19.0 %) have been infected. Surgery was done in 132 wounds (2.5 %).

CONCLUSION

We could show a six times higher infection rate of cat bites compared to dog bites. Human bites showed a total infection rate of 8.2 %. Observed infection rate of puncture wounds and wounds greater than 3 cm was 1.5 times higher than for all other wounds in the present study. Total infection rates within 24 h to antibiotic administration was 29.3 %, compared to 65.0 % < 48 h and 81.1 % < 72 h. Time interval also influenced the overall outcome showing a 2.6 increase in acceptable and 1.3 increase in poor outcome after 72 h.
