Project 033 – Dental PEARLS: Dental Penicillin Allergy ReferraL study

Introduction

Around 10% of the Australian population have a reported penicillin allergy, but of the 10%, only 1% will be correct; the other 9% is in error. This is either because the person had a side effect (e.g. nausea), or the allergy has worn off; 50% of allergies wear off after 5 years. Most rashes reported in association with a penicillin antibiotic during childhood are also not true allergies.

In dentistry, patients who report a penicillin allergy and need an antibiotic, will usually be prescribed clindamycin. Clindamycin has a much higher side effect profile and is more toxic than amoxicillin. While dentists are encouraged to appropriately screen and refer patients for penicillin allergy testing, there is no direct pathway for dentists to do so.

Aims

  • To determine the proportion of penicillin allergic patients with a low-risk penicillin allergy phenotype assessed by dentists.
  • To determine the proportion of patients referred by dentists with a low-risk penicillin allergy that can have their penicillin allergy label removed by testing
  • To assess this method for dentists to appropriately screen and refer patients for penicillin allergy de-labelling as there is no current method for dentists do to this.

Who can participate?

Dentists and dental specialists who:

  • are practising in Victoria; and
  • have access to the internet. 

What will you be asked to do?

Screen and refer eligible patients using a simple online questionnaire that should take around 1-2 minutes per patient.

Why should you participate?

This study provides a wonderful and simple opportunity for you to screen and refer your patients directly for penicillin allergy testing to Austin Health.

While the normal wait list is usually around 2 years, your patients will be fast-tracked to the low-risk clinic that operates on a Friday at the Austin Hospital Centre for Antibiotic Allergy and Research, and the wait time will only be around 4 weeks.

It is anticipated that around 90% or more of the patients referred for testing will show that the patient is actually not allergic to penicillin. This will enable safer and more appropriate antibiotic prescribing for these patients.

Project 030 – Effectiveness of pre-treatment music as an intervention to manage anxiety in the dental setting

Introduction

Dental anxiety is common in the general population and has been identified as a barrier to people accessing timely and appropriate professional care. Listening to music during a dental procedure has been associated with a reduction in the experience of dental anxiety, accompanied by physiological changes such as reductions in heart rate, blood pressure and respiratory rates, but there is a lack of research investigating the effect of music provide pre-treatment and/or during treatment.

Aims

To explore the effectiveness of pre-treatment music in the management of dental anxiety in general practice.

Who can participate?

General dentists who practice in metropolitan Melbourne.

What will you be asked to do?

  • (With the help of your team) ask your patients who meet the inclusion criteria (over 18 years of age who have an appointment for dental fillings) if they would be willing to participate in the study by completing a questionnaire (Modified Dental Anxiety Scale) before treatment starts. Patients with a score of 11 or higher will be invited to participate by completing a further questionnaire on arrival for their appointment and wearing on-ear headphones and a pulse monitor while in the waiting room and surgery. They will be randomly assigned to one of three study groups:
    • Music before and during dental treatment
    • Music during dental treatment only
    • No music (control group)
  • Recruit up to 21 patients to participate in the study (7 patients will be randomly assigned to each study group).
  • Become an eviDent member (membership is free) and complete the minimum training requirements as well as additional training for this project, for which CPD credit will be provided.

Why should you participate?

  • You and your practice may benefit from the outcomes of this study, leading to increased professional satisfaction and wellbeing;
  • Be part of an eviDent project that will ultimately contribute to the practice of dentistry in Australia.
