OCH-A-DRARRmnemonic for treatment of localized infection; see Table 1
|O||Operate||Remove the cause of the infection where possible, e.g. remove focal hyperkeratosis/foreign body/nail spike|
|C||Cleanse||Irrigate area/cleanse cavity with Warmasol delivered under pressure from a sterile syringe|
|H||Heat||Assist drainage of pus/exudate by applying heat, e.g. immersion in a warm hypertonic NaCl bath|
|A||Antiseptic||Apply a liquid or powder antiseptic (e.g. Betadine)|
|D||Dress||Cover the lesion with a sterile dressing (e.g. sterile gauze; Lyofoam)|
|R||Rest||Impose rest, e.g. deflective padding; shoe modification; walking cast; crutches, as necessary|
|A||Reappoint||Arrange to review case in 24–72 hours|
|R||Review||At the subsequent appointment, review progress|
If resolution has been initiated, continue to treat as above (O–A) and review weekly until healing is complete
If the infection has not improved, arrange for antibiosis, and continue to review and dress until healing is complete
|R||Refer||Refer for specialist review via GP: remember, slow-to-resolve infection can characterize undiagnosed diabetes, or other ‘at-risk’ patient category|
Use all normal preoperative procedures; keep infected lesions covered until ready to treat; take a swab for pathology laboratory analysis of any exudate; use a sterile dressings pack; follow the OCH-A-DRARR treatment mnemonic.
‘At-risk’ patients presenting with infection or patients presenting with acute or spreading infection should be treated using the OCH-A-DRARR protocol, but provided with or referred for immediate antibiosis.
