Don’t routinely use microbiologic testing in the evaluation and management of acne.

Bacteria are only one of several factors that contribute to acne. Microbiologic testing, used to determine the type of bacteria present in an acne lesion, is generally unnecessary because it does not affect the management of typical acne patients. Microbiologic testing should be considered only when acne has failed to respond to conventional treatments, particularly in patients who have already been treated with oral antibiotics.

How The List Was Created

The American Academy of Dermatology (AAD) is strongly committed to dermatologists serving as effective stewards of limited health care resources by assisting patients in making informed health care decisions. As such, the AAD leadership created a workgroup to develop this list with specific skills and expertise in evidence based research, public health quality and payer policy. Members of this workgroup include dermatologists who are current members of the Academy’s Board of Directors, Council on Science and Research, Council on Government Affairs, Health Policy and Practice, Research Agenda Committee, Clinical Guidelines Committee, Access to Dermatology Care Committee, Patient Safety and Quality Committee, Resource-Based Relative Value Scale Committee and the Workgroup on Innovative Payment Delivery. The workgroup identified areas to be included on this list based on the greatest potential for overuse/misuse, quality improvement and availability of strong evidence based research as defined by the recommended criteria listed below. The recommended list was reviewed and approved by the AAD Council on Science and Research and the AAD Board of Directors.

  • Supported by available scientific evidence (e.g., existing AAD appropriate use criteria and/or existing AAD clinical guidelines)
  • Strongest consensus inappropriate score from the AAD Appropriate Use Criteria (AUC)
  • Strong (wording/level of evidence) recommendations from the guidelines about discouraged practice
  • Greatest potential for improvement in outcomes for patients
  • Greatest potential for overuse/misuse by physicians
