Input: Three RCTs were identified, comprising a total of 847 participants. One trial compared silver-containing foam (Contreet®) with hydrocellular foam (Allevyn®) in patients with leg ulcers. The second trial compared a silver-containing alginate (Silvercel®) with an alginate alone (Algosteril®). The third trial compared a silver-containing foam dressing (Contreet®)) with best local practice in patients with chronic wounds. The data from these trials show that silver-containing foam dressings did not significantly increase complete ulcer healing as compared with standard foam dressings or best local practice after up to four weeks of follow-up, although a greater reduction of ulcer size was observed with the silver-containing foam. The use of antibiotics was assessed in two trials, but no significant differences were found. Data on pain, patient satisfaction, length of hospital stay, and costs were limited and showed no differences. Leakage occurred significantly less frequently in patients with leg ulcers and chronic wounds treated with a silver dressing than with a standard foam dressing or best local practice in one trial. Only three trials with a short follow-up duration were found. There is insufficient evidence to recommend the use of silver-containing dressings or topical agents for treatment of infected or contaminated chronic wounds.
Output:

Three studies looking at people with chronic wounds were included in the review and found that silver-containing foam dressings did not result in faster wound healing after up to four weeks of follow-up. One study did find that the overall size of the ulcer reduced more quickly when dressed with a silver-containing foam. There is no enough evidence to recommend the use of silver-containing dressings or topical agents for treating infected or contaminated chronic wounds.
