To describe an approach that allows for a streamlined assessment and accurate differentiation of most patients with itch in primary care and to provide an update on the available nonpharmacologic, topical, and systemic therapies.
MEDLINE (Ovid) and PubMed were searched for the key words or Searches were refined for each cause and treatment by adding appropriate key words, and subsequent hand searches of the references of retrieved literature were performed.
A good body of evidence from high-quality trials does not exist for treatment of pruritus, and the treatments that do exist are inconsistent in their success. The dominant causes of generalized itch are xerosis and eczema. Most patients will improve with nonpharmacologic therapy including frequent moisturization. If this avenue fails, further investigations are warranted to help guide subsequent treatment with any of the many cause-specific topical and systemic approaches available.
Chronic itch can be debilitating for patients. The approach described allows for a streamlined assessment and accurate differentiation of most patients with itch in primary care.
描述一种方法，以便在初级保健中对大多数瘙痒患者进行简化评估和准确区分，并提供有关非药物、局部和全身治疗方法的最新信息。
在 MEDLINE（Ovid）和 PubMed 上搜索关键词[pruritus]或[itch]。通过添加适当的关键词对每种病因和治疗方法进行了搜索细化，并对检索文献的参考文献进行了后续的手工搜索。
高质量试验并未提供治疗瘙痒的大量证据，而且现有的治疗方法在疗效上并不一致。全身性瘙痒的主要原因是干燥和湿疹。大多数患者将通过非药物治疗（包括经常保湿）得到改善。如果这条途径失败，则需要进一步调查以帮助指导随后针对许多特定病因的局部和全身治疗方法中的任何一种进行治疗。
慢性瘙痒会使患者身体虚弱。所描述的方法允许在初级保健中对大多数瘙痒患者进行简化评估和准确区分。
