目的了解公共卫生医师群体对处方权的态度，为进一步探索赋予公共卫生医师处方权的政策制定和推动提供支撑和参考。方法采用关键人物法和滚雪球法，对四川省各级疾病预防控制中心、医院、妇幼保健院、基层医疗机构、专业公共卫生等多类机构的公共卫生医师开展在线横断面问卷调查。对246份问卷关于公卫医师对处方权现状、认知、影响、态度和建议进行定性、定量分析。结果约95%的参与者支持赋予公共卫生医师处方权，认为赋予处方权是对公共卫生“医师”身份认同的标志，可以促进防治结合，提升公共卫生体系的工作效率和质量，促进公共卫生医师医学专业能力提升，从而改善公共卫生工作的质量和效果；而没有处方权会降低医学同行对公共卫生医师医学专业性的认可以及公共卫生医师开展公共卫生工作的效果。对不同形式的处方权获得方式，多数参与者表示愿意接受。结论公共卫生医师群体对处方权的需求意愿高，认为推行公共卫生医师处方权是改善公共卫生医师医防分离现状，推动公共卫生医师高质量发展的一项重要措施。
