Final answer:
Deliberate indifference to medical needs, as defined in Estelle vs Gamble (1976), refers to prison officials intentionally disregarding an inmate's serious medical condition or need for treatment.
Step-by-step explanation:
In the case of Estelle vs Gamble (1976), deliberate indifference to medical needs refers to a situation where prison officials intentionally and callously disregard an inmate's serious medical condition or need for medical treatment.
Deliberate indifference can be shown through a prison official's actions or omissions, such as denying or delaying necessary medical care, ignoring obvious symptoms, or providing grossly inadequate treatment.
For example, if a prisoner has a known and serious medical issue, but the prison officials fail to provide timely and appropriate medical attention, it may be considered deliberate indifference to their medical needs.
