The impact of switching from single-use to reusable healthcare products: a transparency checklist and systematic review of life-cycle assessments.

Switching to reusable healthcare products is likely to reduce most impacts on the environment except water use, but the effect size differs among product categories. Possible study limitations include location bias, no systematic search of the grey literature and small samples for some impacts. This study's strengths are its approach to product categories and developed transparency catalogue. This catalogue could be useful to inform and guide a future process towards creating a standardized transparency checklist for the systematic reviews of LCAs.
