What Are the Four Elements of Medical Malpractice?

The four elements of medical malpractice are duty of care, breach of that duty, causation and damages. In plain English, a provider owed you care, failed to meet that obligation, caused harm through that failure, and left you with an injury or loss. A claim needs all four elements. An upsetting result alone doesn't establish malpractice.

If someone mentions the “four Ds”, they mean duty, dereliction or deviation, direct cause, and damages. That doesn't change the elements. When you separate the elements, you can explain your concerns without deciding yourself whether the care was negligent.

The four elements at a glance

1. Duty of care: the provider's obligation to you

Duty begins when there's a patient-provider relationship. Ask whether the provider had a professional obligation to care for you. As Understanding the Four Ds of Medical Malpractice explains, this first element is the doctor-patient relationship.

Begin with the provider who treated you, telling the lawyer whose care you're questioning and how that provider was involved. Don't mix your concerns into that account, because responsibility for your care doesn't show whether the care fell short.

2. Breach of duty: the failure in care

If a provider doesn't meet the duty they owe a patient, that's a breach. That's negligence in some explanations. Feeling disappointed or frightened afterward doesn't establish a breach, whatever term you use for failed care (“dereliction” or “deviation”).

Don't leave your concerns vague. Describe what the provider did or what you think they didn't do, noting anything you're unsure about. You can ask a lawyer to review your concern without turning a suspicion into a medical conclusion first.

If care ends badly, that doesn't prove a breach. Ask whether the provider fell short of the care owed to the patient before you consider a claim.

3. Causation: the connection to your injury

Causation means the harm came from failed care. As Demystifying the 4 Elements of Negligence explains, a breach of duty gives rise to causation, which it calls “proximate cause or causal connection”. You may also see it called “direct cause.”

You need that link. You need a link between deficient care and your injury. An injury alone doesn't tell you what the provider did, or didn't do, to cause it.

Tell the lawyer what happened during your care and how you were hurt afterward, as clearly as you can. If you're guessing about something, don't present it as fact. To see whether that link supports a claim, a lawyer can use the rules where you received care.

4. Damages: the harm you suffered

Damages means the injury or loss that negligence caused you. Don't fold this element into the others. When you describe the harm for damages, you're also touching on causation: why that harm happened.

Explain how you were injured before you start talking about a dollar figure. What problems is it causing you now? Tell the lawyer when you meet if you suspect a mistake but can't point to any harm that came from it.

Why all four elements matter

To prove malpractice, you'll need each of the four elements. That leaves the other elements to prove. Even if you've shown a breach, you still need to connect it to damages; duty alone doesn't prove breach.

Your state or province determines which rules apply. Before you ask a lawyer in your state or province how the rules apply to you, read our state resources or Canadian resources. This is general information, not legal advice for you.

What to do next

Put the provider whose care you're questioning first in your notes, then describe what you suspect went wrong and the harm you believe followed. Mark any gaps you're unsure about instead of filling them in.

You can request a case review with that account. When asking which of the four elements needs closer attention, ask what would help the lawyer assess it. Before asking for an assessment, you don't need to know if your claim is viable.
