Hospital-acquired infections affect hundreds of thousands of patients annually in the United States. These infections—including MRSA, C. difficile, catheter-associated urinary tract infections, surgical site infections, and central line-associated bloodstream infections—cause significant morbidity and mortality. Yet infection doesn’t automatically mean malpractice. Proving liability requires showing that negligent infection control, not the inherent risks of healthcare, caused your infection.
Understanding the distinction between preventable and non-preventable infections helps evaluate whether a malpractice claim exists. The analysis is complex because some infection risk exists even with perfect care, but substandard infection prevention practices substantially increase that risk.
When Infections Become Malpractice
Not every hospital-acquired infection results from negligence. Hospitals are environments where sick people congregate, invasive procedures occur, and antibiotics create resistant organisms. Some infection risk exists despite best practices.
Malpractice exists when the infection resulted from failure to follow accepted infection prevention standards. The question is whether the hospital, its staff, or its physicians fell below the standard of care in preventing your infection.
Common negligence theories in infection cases include: failure to follow hand hygiene protocols, improper sterilization of surgical instruments, failure to follow central line insertion bundles, improper urinary catheter management, failure to implement contact precautions for known carriers of resistant organisms, inadequate environmental cleaning, and understaffing that prevents proper infection control.
The challenge is proving that negligent practices, rather than unavoidable infection risk, caused your specific infection. This typically requires expert analysis connecting identifiable failures to your infection.
Proving Causation in Infection Cases
Causation presents particular difficulty in infection cases. You must typically show not just that the hospital was negligent in infection control, but that their negligence caused your specific infection.
This can be proven several ways. Direct evidence of contamination—an infected surgical instrument, a contaminated medication batch, a staff member with the same infection strain—directly connects negligence to your infection. This evidence is rarely available but is powerful when it exists.
Epidemiological evidence may show patterns suggesting negligence. If multiple patients developed the same infection in the same time period, an outbreak investigation may reveal the source. Hospital infection control records, if obtainable, may document known problems.
Circumstantial evidence combined with expert testimony can establish causation. If you entered the hospital without infection, underwent a procedure with infection risk, and developed an infection that commonly results from that procedure, experts can testify about the likelihood that identifiable negligence caused your infection.
Proving what didn’t happen—that required infection prevention steps weren’t taken—requires documentation review and sometimes discovery of hospital policies, training records, and staffing information. Documentation that hand hygiene was performed doesn’t prove it actually was; documentation that it wasn’t performed strongly suggests it wasn’t.
Types of Hospital-Acquired Infections
Different infection types involve different analysis.
Surgical site infections occur when the surgical wound becomes infected. Standards require preoperative skin preparation, appropriate antibiotic prophylaxis, sterile technique during surgery, and proper wound care afterward. Failures in any of these areas may constitute negligence. However, some surgical site infections occur despite perfect technique, particularly in certain types of surgery and in patients with risk factors.
Central line-associated bloodstream infections (often called CLABSIs) result from bacteria entering the bloodstream through central venous catheters. Evidence-based “bundles” of practices substantially reduce these infections—hand hygiene, barrier precautions during insertion, chlorhexidine skin preparation, optimal site selection, and prompt removal of unnecessary catheters. Failure to follow bundle elements is strong evidence of negligence.
Catheter-associated urinary tract infections result from bacteria entering the urinary system through indwelling catheters. Standards require appropriate indications for catheter use, aseptic insertion, proper maintenance, and prompt removal when no longer needed. Unnecessary catheter use or prolonged catheterization beyond medical necessity may constitute negligence.
Clostridioides difficile infections often result from antibiotic use disrupting normal gut bacteria. While some C. diff infections occur without negligence, inappropriate antibiotic prescribing or failure to implement contact precautions around known C. diff patients may constitute negligence.
MRSA and other resistant organism infections present complex causation questions. These organisms can colonize patients before hospitalization. However, failure to screen appropriately, failure to implement precautions for known carriers, and practices that facilitate transmission may constitute negligence.
Hospital Liability Theories
Hospitals may be liable under several theories.
Vicarious liability makes hospitals responsible for negligence by their employees. Nurses, patient care technicians, and other staff who fail to follow infection control protocols create hospital liability through their employment relationship.
Direct institutional negligence addresses hospital-level failures. Inadequate staffing that prevents proper infection control, failure to maintain sterile processing, inadequate training on infection prevention, and failure to implement evidence-based protocols are institutional failures that don’t depend on identifying specific negligent employees.
Corporate negligence addresses failures in hospital systems and oversight. If the hospital knew or should have known about infection control problems and failed to address them, corporate negligence may apply.
Physician liability is complicated by whether physicians are hospital employees or independent contractors. Many physicians have privileges at hospitals but aren’t hospital employees. Their negligence may not create hospital liability depending on the circumstances and state law regarding apparent agency and non-delegable duties.
Evidence and Discovery in Infection Cases
Infection cases often require obtaining evidence beyond standard medical records.
Hospital infection control records document infection rates, outbreaks, investigations, and interventions. These records may reveal patterns suggesting systemic problems.
Staffing records may show inadequate nurse-to-patient ratios that prevented proper care. Research connects staffing levels to infection rates.
Policy and procedure documents establish what the hospital’s own standards required. Deviation from the hospital’s own protocols is evidence of negligence.
Training records show whether staff received required infection control education.
Equipment maintenance records may reveal sterilization failures or equipment problems.
Environmental cleaning records document whether required cleaning occurred.
State health department inspection records, CMS survey results, and accreditation reports may reveal known problems.
Obtaining these records typically requires litigation. Hospitals don’t voluntarily produce internal documents suggesting their negligence. Formal discovery through litigation, including interrogatories, document requests, and depositions, is usually necessary.
Damages in Infection Cases
Infection damages vary enormously depending on outcomes.
Minor infections that resolve with antibiotic treatment may cause modest damages: additional medical expenses, extended hospitalization, some pain and suffering. These cases may not justify the cost of litigation.
Severe infections can cause catastrophic damages: extended ICU stays, multiple surgeries, organ failure, amputation, permanent disability, or death. These cases justify substantial litigation investment and can result in significant recoveries.
Sepsis particularly can cause devastating outcomes. When infection spreads to the bloodstream and triggers systemic response, organ failure and death can follow rapidly. Survivors of severe sepsis often experience long-term complications.
The infection’s connection to your original hospitalization affects damage calculation. If you were hospitalized for a minor procedure and developed a severe infection, the damages attributable to the infection are substantial. If you were already critically ill and developed an infection that complicated recovery, attributing specific damages to the infection versus your underlying condition becomes more complex.
Practical Considerations
Infection cases present practical challenges.
Expert witnesses must address both infection control standards and causation. Infectious disease specialists, infection preventionists, and nursing experts may all be needed. The cost of developing infection cases can be substantial.
Hospitals vigorously defend infection cases because infection is common and proving specific negligence is difficult. Defense arguments typically emphasize that infection occurs despite best efforts and that the plaintiff can’t prove specific negligent acts caused their specific infection.
Timing matters because investigation of infections while still hospitalized may be possible. If you or a family member develops a serious hospital-acquired infection, documenting everything contemporaneously, requesting that the hospital investigate, and consulting an attorney before discharge may preserve evidence that becomes unavailable later.
Regulatory reporting requirements mean some infection data is publicly available. CMS publishes hospital-acquired condition rates, and some states require public reporting of certain infections. This data can help identify hospitals with infection problems, though it doesn’t prove negligence in specific cases.
Important Disclaimer
This article provides general educational information about legal claims for hospital-acquired infections. It is not legal advice and should not be relied upon as such.
This information may be inaccurate, incomplete, or outdated. Laws regarding hospital liability, evidence requirements, and damage rules vary by state. Infection science continues evolving. The specific facts of your situation substantially affect what claims may exist.
Do not make legal decisions based on this article. Hospital-acquired infection cases require specialized analysis of complex medical evidence and causation questions that general information cannot address.
Consult a qualified medical malpractice attorney licensed in your state before taking any action. Only a licensed attorney working with appropriate medical experts can evaluate whether your specific infection resulted from negligence and whether a viable claim exists.
If you or a family member has developed a serious hospital-acquired infection, act promptly. Consult an attorney while still hospitalized if possible. Request that the hospital investigate the infection source. Document your observations. Obtain records promptly. Evidence relevant to how infections occurred may disappear over time.
