Hospital Missed Sepsis in California: Can You Sue, and How Long Do You Have?

When is a missed sepsis diagnosis malpractice?

Sepsis is the body’s extreme reaction to an infection. It can start from something common, like a urinary tract infection, pneumonia or an infected surgical wound, and it can get worse within hours. The early signs can look like the flu or dehydration, which is why hospitals are expected to watch for it. A sepsis malpractice claim asks whether the care team noticed the warning signs and acted on them the way reasonable providers would have.

Under California’s jury instructions, a health care professional is negligent if they fail to use the skill, knowledge and care in diagnosis and treatment that other reasonably careful practitioners would use in the same or similar circumstances (CACI No. 501). A bad outcome alone does not meet that test. The questions are whether the delay fell below that standard and whether earlier treatment would have made a difference for the patient.

Sepsis claims often involve a patient who was sent home from the emergency room with a fever and came back much sicker, lab results that were ordered and never acted on, or an infection after surgery that nurses charted but no doctor treated. Each of these leaves a trail in the medical record. That trail, read by a doctor who reviews cases, is usually where a claim begins or ends.

What Medicare publishes about each hospital’s sepsis care

Medicare’s Care Compare program publishes, for each hospital, the percentage of patients with severe sepsis or septic shock who received appropriate care under a measure called SEP-1 (Medicare Timely and Effective Care data, SEP-1). Medicare also publishes each hospital’s infection ratios against a national benchmark for infections such as central line bloodstream infections, MRSA bloodstream infections and C. difficile (Medicare hospital infection data).

You can look up the hospital where you or your family member was treated in our Los Angeles County hospital records hub, which shows each hospital’s Medicare data and state health department records in one place. A hospital-wide percentage describes the hospital as a whole. It can help you ask better questions, and a lawyer will look at it next to the chart.

In a sepsis case the timing in the chart usually matters most. When did the vital signs change? When were blood cultures and lab work ordered, and when did the results come back? When were antibiotics ordered, and when did the nurse actually give them? Those times are recorded in nursing notes, flowsheets and the medication record, and they are often the heart of the case.

How long do you have to sue for missed sepsis?

A California malpractice lawsuit generally must be filed within three years after the injury or one year after the patient discovers, or reasonably should have discovered, the injury, whichever comes first (Code of Civil Procedure 340.5). The one-year period starts when you know of the injury and its negligent cause, or have information that would make a reasonable person suspect wrongdoing and look into it. You do not need to know every fact (Sanchez v. South Hoover Hospital (1976) 18 Cal.3d 93).

For a delayed diagnosis, the injury that starts these periods is the first appreciable harm from the missed diagnosis, which happens when the undiagnosed condition develops into a more serious one (Drexler v. Petersen (2016) 4 Cal.App.5th 1181). That can come after the visit where the signs were missed. With sepsis the harm usually shows up fast, so families should assume the clock is already running.

Before filing, you must give the provider at least 90 days’ written notice of your intent to sue (Code of Civil Procedure 364). If the hospital belongs to a county, a written government claim generally must be presented within six months (Government Code 911.2), and you can read how that works on our page about suing a county or UC hospital. Our guide to California malpractice deadlines covers the rest.

When sepsis leads to a death

When a death results from medical negligence, the claim is a medical malpractice claim, so the deadline in Code of Civil Procedure 340.5 and the MICRA wrongful death cap on non-economic damages apply. The cap in effect when the judgment, award or settlement is reached controls, and in 2026 it is $650,000 per category. Up to three separate caps can apply in one case (Civil Code 3333.2).

In a death case, the three-year period runs from the date of death, and the one-year period runs from when the family discovered, or should have discovered, the negligent cause of the death (Larcher v. Wanless (1976) 18 Cal.3d 646). Families often learn what went wrong only after reading the chart or an autopsy report, so the date they suspected a mistake matters.

The claim can be brought by the surviving spouse or registered domestic partner, the children, and the children of a deceased child. If there are none, it goes to those who would inherit under California law, and certain dependents, such as parents, can also sue (Code of Civil Procedure 377.60). Our page on wrongful death from medical malpractice explains this in more detail.

How a sepsis malpractice case is proved

Expert testimony is generally required in a California malpractice case to prove the standard of care, the breach and causation (CACI No. 501, Directions for Use). In a sepsis case that usually means a physician who reads the full chart and explains what a reasonably careful emergency doctor, hospitalist or nurse would have done with the same signs, and whether faster treatment would have changed the result.

The hospital can be responsible even when the doctor was an independent contractor. Under ostensible agency, a hospital can be liable for that doctor’s negligence when the patient looked to the hospital for care and was not put on notice that the doctor was not a hospital employee (Mejia v. Community Hospital of San Bernardino (2002) 99 Cal.App.4th 1448). A hospital also has its own duty to use reasonable care in selecting and reviewing the doctors it allows to practice there (Elam v. College Park Hospital (1982) 132 Cal.App.3d 332).

In an injury case, the 2026 MICRA cap on non-economic damages is $470,000 per category. Lawyer fees in malpractice cases are capped at 25 percent if the case settles before a lawsuit or arbitration demand is filed, and 33 percent after (Business and Professions Code 6146). If the care was at Kaiser, the claim generally goes to binding arbitration instead of a lawsuit, because Kaiser members agree to that when they enroll.

What to do now

Ask for the medical records in writing. California patients and their representatives can inspect records within 5 working days of a written request and receive copies within 15 days (Health and Safety Code 123110). Ask for the complete chart, including emergency room notes, nursing notes, vital sign flowsheets, lab results with their times, and the medication administration record that shows when antibiotics were given.

Write down what you remember while it is fresh: the dates of each visit, the names of the doctors and nurses, what symptoms were reported, and what you were told at discharge. Keep discharge papers and any bills. If the hospital’s insurer or risk management office contacts you, do not sign anything before you talk to a lawyer. Then call a lawyer soon, because the one-year period may already be running.

• Request the full chart in writing, including nursing notes and the medication record.
• Write down dates, names and what you were told at each visit.
• Do not sign anything from the provider’s insurer or risk management office.
• Talk to a malpractice lawyer before the one-year period runs out.
