You can sue a hospital for an infection you caught during your care, but only if that infection resulted from the hospital’s failure to follow accepted safety practices and you can prove the failure caused you real harm. About 1 in 31 hospital patients picks up an infection during a stay, according to the CDC, and many of those infections are an unavoidable risk of treatment.1Centers for Disease Control and Prevention. Current HAI Progress Report Others trace back to lapses in hygiene, sterilization, or protocols that a competent facility would have caught. The difference between an unfortunate complication and a viable lawsuit is whether someone deviated from the standard of care.
When a Hospital Infection Becomes Negligence
Not every infection you pick up in a hospital means someone did something wrong. Bacteria live on skin, in the gut, and throughout hospital environments. Surgery creates openings, catheters introduce foreign objects, and immunosuppressive treatments lower your defenses. Some infections happen despite flawless care. A lawsuit only makes sense when the infection resulted from a failure to do what a competent hospital would have done under the same circumstances.2Legal Information Institute. Standard of Care
The failures that cross the line into negligence tend to fall into recognizable patterns: surgical instruments that weren’t properly sterilized, staff who skipped hand hygiene between patients, central lines left in longer than necessary, catheters that weren’t removed when they should have been, or wound dressings changed too infrequently. Systemic lapses count too. If a hospital knew MRSA was spreading through a unit and didn’t implement isolation protocols, that’s an institutional failure, not an individual mistake.
The infections most commonly at the center of these lawsuits include:
- Surgical site infections at or near the incision after an operation
- Central line-associated bloodstream infections (CLABSI), when bacteria enter the blood through an IV catheter placed in a large vein
- Catheter-associated urinary tract infections (CAUTI), from urinary catheters left in too long or inserted without proper technique
- Drug-resistant infections like MRSA and C. difficile, which spread rapidly when protocols break down
The federal government treats several of these as preventable. Medicare classifies certain hospital-acquired infections as conditions that should not occur with proper care, and hospitals don’t receive additional payment when one develops during a patient’s stay.3Centers for Medicare & Medicaid Services. Hospital-Acquired Conditions
What You Have to Prove
Every medical malpractice claim for a hospital-acquired infection requires four elements. Miss one and the case fails, no matter how strong the others are.4National Center for Biotechnology Information. An Introduction to Medical Malpractice in the United States
- Duty of care. The hospital owed you a professional obligation. This exists from the moment the hospital admits you or begins treating you.
- Breach of duty. The hospital or its staff fell below the accepted standard of care. You need to show what a competent hospital would have done and how this one fell short.
- Causation. The breach is what actually caused your infection. This is where most infection cases live or die, because you must show the infection wouldn’t have occurred (or would have been less severe) without the negligence.
- Damages. You suffered real, measurable harm. Additional surgeries, extended hospitalization, lost income, lasting disability, and pain all count. If the infection resolved quickly with no meaningful consequences beyond what your treatment already involved, there may not be enough harm to support a claim.
Why These Cases Are Harder Than They Look
Hospital-acquired infection cases are among the most difficult medical malpractice claims to win. Two challenges in particular trip people up.
Proving the Hospital’s Failure Caused Your Infection
Infections don’t come with a label explaining what triggered them. A patient who develops a surgical site infection might have been carrying the bacteria on their own skin before the operation. Someone who gets C. difficile might have been predisposed because of antibiotics prescribed for a legitimate reason. The hospital’s defense will almost always argue that the infection could have happened even with perfect care.5National Center for Biotechnology Information. Medico-Legal Aspects of Hospital-Acquired Infections
You don’t have to rule out every other possible cause, but you do have to show that the hospital’s failure more likely than not caused the infection. That usually requires an expert who can trace the chain from the specific protocol violation to the type of organism involved to the timing and location of the infection. Vague arguments about a “dirty hospital” won’t move the needle.
Finding a Qualified Medical Expert
In nearly all malpractice cases you need a qualified medical expert to testify about what the standard of care required and how the hospital fell short. The rare exceptions involve negligence so obvious that no medical knowledge is needed to spot it, like an instrument left inside a patient’s body.6National Center for Biotechnology Information. The Expert Witness in Medical Malpractice Litigation Infection cases almost never fall into that obvious category. You’ll need an expert in infection control or the relevant surgical specialty who can explain to a jury exactly what went wrong.
Many states set minimum qualifications for who can serve as a medical expert witness in malpractice cases, typically requiring the expert to be licensed, trained in the same specialty as the defendant, and actively practicing. Finding one willing to testify against a hospital is its own challenge. These professionals work in the same industry as the people they’d be criticizing, and some are reluctant to do it.
Who You Actually Sue
This question matters more than most people realize. When a hospital employs its nurses, technicians, and staff directly, the hospital is liable for their negligent acts under standard employer-liability principles. But many physicians who treat you in a hospital are not hospital employees. They’re independent contractors with privileges to practice there, and that distinction can shield the hospital from liability for a doctor’s negligence in some situations.
Courts in many states have pushed back through a theory called ostensible agency. If you went to the hospital rather than to a specific doctor, and the hospital held that physician out as part of its care team, the hospital can still be liable even if the doctor technically works independently. From a patient’s perspective, the surgeon introduced by the hospital’s pre-op nurse looks like a hospital doctor, and many courts agree the hospital shouldn’t escape responsibility because of contract language the patient never saw.
For infection cases specifically, the liability picture is often broader than any single doctor’s conduct. Infection control is an institutional responsibility. Hand hygiene policies, sterilization protocols, staffing levels, and surveillance systems are hospital-level decisions. When the failure is systemic, meaning not enough cleaning staff, broken autoclave equipment, or no isolation procedures during an outbreak, the hospital itself is the proper defendant regardless of any individual provider’s employment status.
Deadlines That Can End Your Case Before It Starts
Every state sets a strict deadline for filing a medical malpractice lawsuit. Miss it and your claim is gone, no matter how strong the evidence. Deadlines vary considerably. Most fall between one and three years, though some states allow longer.7Justia. Statutes of Limitations and the Discovery Rule in Medical Malpractice Lawsuits
The Discovery Rule
The clock doesn’t always start on the date of your surgery or hospital stay. Many states follow the discovery rule, which delays the start of the limitations period until the date you knew, or reasonably should have known, that you were injured and that the injury may have been caused by negligence.7Justia. Statutes of Limitations and the Discovery Rule in Medical Malpractice Lawsuits This matters for infections because symptoms sometimes don’t appear until days or weeks after discharge. If you developed sepsis two weeks after surgery and didn’t connect it to the hospital’s care until a follow-up doctor pointed it out, the discovery rule could give you more time.
The “reasonably should have known” language matters. Courts expect you to investigate suspicious symptoms. If a reasonable person in your position would have sought medical attention sooner and discovered the negligence, the clock may have started running before you actually made the connection.
Statutes of Repose
Many states also impose an absolute outer deadline called a statute of repose. Unlike the statute of limitations, a statute of repose runs from the date of the negligent act and cannot be extended by the discovery rule. Even if you had no way of knowing about the infection or its cause, the repose deadline can shut the door. Not every state has one, and outer limits vary.
Special Rules for Children
If the patient is a minor, most states pause the statute of limitations until the child reaches the age of majority (18 in most states). Some states set an absolute deadline tied to the child’s birthday regardless of when the limitations period would otherwise expire. A parent or guardian can file on the child’s behalf at any time before the deadline runs.
Pre-Suit Certificates and Notices
Roughly half the states require a certificate of merit (sometimes called an affidavit of merit) before you can file or shortly after. This is a formal document in which a qualified medical expert certifies that they’ve reviewed your case and believe the hospital breached the standard of care. Filing without one in a state that requires it can get the case dismissed before it starts.
Some states also require pre-suit notice. You have to notify the hospital of your intent to sue and wait a specified period, commonly 60 to 90 days, before filing. Missing this step can also result in dismissal. These requirements exist to screen out frivolous claims, but they create real traps for patients who try to handle things without an attorney.
First Steps If You Think You Have a Case
Request Your Medical Records
Under federal law, you have a right to obtain copies of your medical records from any hospital or healthcare provider that conducted certain transactions electronically, which covers virtually every hospital in the country.8U.S. Department of Health & Human Services. 45 CFR 164.524 – Individuals’ Right under HIPAA to Access their Health Information Submit a written request to the hospital’s medical records department. The hospital must respond within 30 calendar days and can take an additional 30 days if it provides a written explanation for the delay.9U.S. Department of Health & Human Services. How Timely Must a Covered Entity Be in Responding to Individuals’ Requests for Access
Request everything: admission notes, physician orders, nursing charts, lab results, imaging reports, operative notes, infection control records, and discharge summaries. Pay particular attention to nursing notes. They often contain the most detailed, hour-by-hour account of your care and are where protocol lapses are most visible.
Keep Your Own Record
Write down when symptoms first appeared, what you were told by staff, and how the infection progressed. Track every related expense: additional medical bills, pharmacy costs, transportation to follow-up appointments, and lost wages. Note how the infection has affected your daily life, your ability to work, and your physical and emotional wellbeing. This account fills gaps that clinical records often miss.
Talk to a Malpractice Attorney
Medical malpractice attorneys almost universally work on contingency. You pay nothing upfront, and the attorney collects a percentage of the recovery only if you win. That percentage typically runs 33 to 40 percent of the total award or settlement. Case expenses (expert witness fees, medical record costs, deposition fees, filing fees) are usually separate from the attorney’s percentage and can be substantial in infection cases, sometimes reaching tens of thousands of dollars.
Not every infection caused by negligence is worth litigating. If the infection resolved quickly and the damages are modest, the cost of expert witnesses and litigation may exceed what you’d recover. A good attorney will tell you that directly at the initial consultation.
What You Can Recover
Damages in hospital infection cases fall into two broad categories. Economic damages cover measurable financial losses: additional medical bills for treating the infection, future medical care if the infection caused lasting complications, lost wages during recovery, and reduced earning capacity if the infection left you with a permanent disability. These are calculated from actual bills, pay stubs, and expert projections.
Non-economic damages cover the harder-to-quantify harm: pain and suffering, emotional distress, loss of enjoyment of life, and impact on your relationships. These can be substantial when an infection led to extended ICU stays, amputations, organ damage, or chronic conditions.
A significant number of states cap non-economic damages in medical malpractice cases. Caps vary widely. Some states set them around $250,000, others above $750,000, some adjust them annually for inflation, and a handful have no cap at all. Your state’s rule directly affects the maximum value of your case, and your attorney should explain it early.
Alternatives to a Lawsuit
A lawsuit isn’t the only way to hold a hospital accountable, and it isn’t always the right tool. Several reporting channels can trigger investigations and force changes.
File a Hospital Grievance
Every hospital that participates in Medicare (which is nearly all of them) must maintain a formal grievance process under federal regulations. The hospital must have a clearly explained procedure, investigate your complaint, and provide a written response with the results of the investigation and the name of a contact person.10eCFR. 42 CFR 482.13 – Condition of Participation: Patient’s Rights Filing a grievance creates a paper trail and puts the hospital on notice. It won’t produce financial compensation, but it can prompt internal changes and may produce documents useful in a later lawsuit.
Report to Your State Health Department
State health departments oversee hospital safety and can investigate complaints about unsafe conditions, improper care, or infection control failures. You can typically file a complaint through your state’s health department website or by contacting the state survey agency, which handles inspections of healthcare facilities on behalf of both the state and the federal government.11Medicare.gov. Filing a Complaint A substantiated complaint can result in a formal investigation, corrective action plans, or penalties.
Contact The Joint Commission
If the hospital is accredited by The Joint Commission (most are), you can report a patient safety concern directly to that organization. The Joint Commission reviews complaints related to its accreditation standards and can investigate whether the hospital is meeting safety requirements. It won’t resolve individual billing disputes or legal claims, but a complaint can trigger a review that affects the hospital’s accreditation status.
None of these channels replace a lawsuit if your goal is financial compensation. They serve a different purpose: forcing a hospital to fix the problem that harmed you so it doesn’t happen to the next patient. Some people pursue both tracks at once.
