Neb. Rev. Stat. § 44-2810
Malpractice or professional negligence shall mean that, in rendering professional services, a health care provider has failed to use the ordinary and reasonable care, skill, and knowledge ordinarily possessed and used under like circumstances by members of his profession engaged in a similar practice in his or in similar localities. In determining what constitutes reasonable and ordinary care, skill, and diligence on the part of a health care provider in a particular community, the test shall be that which health care providers, in the same community or in similar communities and engaged in the same or similar lines of work, would ordinarily exercise and devote to the benefit of their patients under like circumstances.
