We are retained by both plaintiff and defense counsel to provide objective medical opinions, written reports, and testimony when needed.

These cases frequently involve questions of:
Our role is to clarify whether the care provided met accepted medical and correctional healthcare standards.

These cases include failure to assess severity, inadequate symptom management, and preventable deterioration.
These cases involve instances in which facilities do not adhere to established withdrawal management policies or monitoring requirements.
These cases include failure to continue medications such as:
Abrupt discontinuation of MAT in custody may raise significant clinical and legal concerns, particularly when associated with worsening withdrawal, relapse risk, or serious outcomes.
These cases include failure to send patients to the emergency department or hospital when medically indicated, including methamphetamine and other substance intoxication.

Inadequate medical screening at intake
Failure to monitor or respond appropriately
Systems breakdowns in correctional healthcare delivery

David Medical Services provides independent, evidence-based medical opinions for both sides of correctional litigation. We do not serve as advocacy experts. Our role is to provide objective analysis of the medical care delivered, and whether it aligned with accepted standards.
When the medical issues or records are still unclear, the v-MD™ Early Case Screening offers a limited physician review to help counsel assess whether a withdrawal-related case warrants full expert engagement.
Attorneys may request a brief introductory call with our physician to discuss:
