Whether a nationally certified medical laboratory and its personnel should be measured by a national standard of professional care rather than a local-community standard.
Holding
Yes. Board-certified physicians, hospitals, medical laboratories, and comparable health-care providers in the District of Columbia are governed by a national standard of care, not an exclusively local standard.
Reasoning
Professional malpractice is a form of negligence. The relevant duty is reasonable care under the circumstances, informed by the special knowledge, training, and skill that a professional possesses. Health-care providers therefore must exercise the degree of care and skill reasonably expected of professionals with similar qualifications acting in similar circumstances.
The traditional locality rule developed to protect rural doctors at a time when medical education was uneven, professional communication was limited, and rural practitioners lacked the experience and resources available in urban centers. Those premises do not fit modern medical practice, and they have no meaningful application to the District of Columbia, a major metropolitan medical center with advanced facilities, medical schools, and access to national medical information.
National accreditation and board-certification systems have substantially standardized medical training and proficiency. Modern transportation, professional journals, continuing education, and other channels of communication likewise make medical knowledge broadly available. Patients reasonably rely on a provider's training, certification, and competence, not on an expectation that the provider will meet only a potentially lower local practice.
A local standard can also perpetuate substandard care by allowing a professional to defend negligent conduct merely because others in the same area do it too. The court rejected that result: conduct does not become nonnegligent simply because it is customary in a locality. Medical laboratories perform services closely connected to those of physicians and hospitals and have comparable opportunities to stay current with professional advances, so the same national standard applies to them.
The laboratory conceded that it was nationally certified and held itself out as such. Morrison's expert gave evidence of a national standard requiring a sitting or prone position and medical evaluation after faintness, while defense experts offered a different account based on local practice. That conflict was for the jury to resolve. By instructing the jury to compare defendants only with Washington-area practice, the trial court effectively excluded Morrison's national-standard evidence and committed reversible error. A new trial was required.
