Ascension Saint Thomas Hospital Midtown Medication Lawsuit Lawyers

Ascension Saint Thomas Hospital Midtown Says at Least Four Patients Were Harmed in an Incident Under Investigation, Raising Questions About Medication Safety, Potassium Chloride, Hospital Procedures, and Potential Tennessee Medical Malpractice Claims.

What Parker Waichman LLP Found

• Ascension Saint Thomas Hospital Midtown has acknowledged that at least four patients were harmed during an incident that the hospital reported to Tennessee regulators.
• One affected patient’s family alleges that potassium chloride was mistakenly administered when an epidural was expected during knee replacement surgery, followed by paralysis from the chest down.
• Potassium chloride for injection concentrate is classified by ISMP as a high-alert medication because errors involving the drug can cause severe patient harm.
• Multiple affected patients may make evidence concerning hospital-wide medication procedures, pharmacy practices, labeling, storage, electronic systems, and common sources of error particularly important.
• Tennessee medical malpractice claims generally carry a one-year limitations period and additional pre-suit procedural requirements, making early investigation important.

A serious patient-safety incident at Ascension Saint Thomas Hospital Midtown in Nashville, Tennessee, is under investigation after the hospital acknowledged that at least four patients were harmed in what it initially described as an “event.” According to local news reports, the family of one affected patient alleges that a medication mix-up during surgery resulted in paralysis from the chest down. The patient reportedly entered the hospital for knee replacement surgery and was expected to receive medication through an epidural for pain control, but the family says potassium chloride was administered instead.

The precise sequence of events has not yet been publicly established, and the hospital has not disclosed the circumstances affecting the other patients. Ascension Saint Thomas has stated that it reported the incident to Tennessee regulators on the day it occurred, identified the cause, began an investigation, and implemented corrective safeguards. The hospital’s president and CEO also publicly apologized for the harm to the patients.

The allegations raise questions that extend beyond a single medication administration. When several patients are reportedly harmed during the same hospital event, investigators may examine pharmacy controls, drug storage, labeling, medication preparation, electronic ordering systems, barcode scanning, staffing, communication, operating-room procedures, and the safeguards intended to prevent a dangerous drug from reaching the wrong patient or being administered by the wrong route.

For injured patients and their families, determining exactly what happened may be critical both medically and legally. A serious medication error can cause permanent disability, neurological damage, cardiac complications, extended hospitalization, rehabilitation needs, lost independence, and substantial future medical expenses. When an injury may have resulted from preventable failures in medical care, Tennessee health care liability law can provide a means of determining responsibility and seeking compensation.

What Has Been Reported About the Ascension Saint Thomas Hospital Midtown Incident?

According to WSMV reporting on August 18, 2026, Ascension Saint Thomas Hospital Midtown confirmed that at least four patients were harmed in an incident at the Nashville facility. The hospital has not publicly identified the other patients or described their injuries, citing patient privacy.

One patient’s family told WSMV that their family member had entered the hospital for a knee replacement and was supposed to receive an epidural for pain management during the procedure. The family alleges that potassium chloride was administered instead and that the patient subsequently became paralyzed from the chest down. The patient reportedly remained in intensive care while the family waited to learn whether any neurological function could be restored.

These remain allegations based on currently available reporting. The complete medical record, medication administration record, pharmacy documentation, electronic audit logs, witness accounts, internal investigation findings, and regulatory findings may ultimately provide a much clearer explanation of what occurred.

Ascension Saint Thomas has publicly acknowledged harm involving four patients. Hospital President and CEO Dr. Shubhada Jagasia apologized to the patients and their families and said the hospital had met with the affected families, provided resources and ongoing care, and initiated enhanced safety protocols.

The hospital also said the incident was reported to state regulators on the day it occurred and that its investigation quickly identified a cause and led to corrective safeguards.

Those statements are significant, but they do not by themselves establish legal liability. A medical malpractice investigation generally must determine what happened to each individual patient, what standard of care applied, whether that standard was violated, and whether the violation caused the patient’s injuries.

Why a Potassium Chloride Medication Error Can Be Extremely Dangerous

Potassium is an essential electrolyte involved in nerve conduction, muscle function, and the electrical activity of the heart. Potassium chloride is routinely and appropriately used in medical care when a patient requires potassium replacement. The danger depends heavily on the concentration, dose, route, rate, and circumstances of administration.

Concentrated potassium chloride for injection is recognized by the Institute for Safe Medication Practices as a high-alert medication. ISMP defines high-alert medications as drugs carrying an increased risk of significant patient harm when used incorrectly. Its current acute-care list specifically includes potassium chloride for injection concentrate.

The distinction matters. Potassium chloride is not inherently an improper medication. Hospitals use it every day. The concern arises when the wrong concentration is selected, it is given by an inappropriate route, it is administered too rapidly, it is confused with another medication, or safeguards designed to prevent an error fail.

Medication safety organizations have been warning hospitals about concentrated injectable potassium chloride for decades. ISMP has documented previous fatalities associated with accidental intravenous administration of concentrated potassium chloride before appropriate dilution and has advocated safeguards intended to keep concentrated potassium chloride away from patient-care areas except under tightly controlled circumstances.

That history makes any alleged potassium chloride mix-up a potentially important patient-safety event requiring careful investigation.

How Can a Wrong Medication Reach a Patient During Surgery?

A medication administration error is not necessarily attributable to one individual mistake. Modern hospital medication systems contain multiple checkpoints precisely because human errors can occur. When a dangerous medication reaches a patient, investigators may need to work backward through the entire medication-use process.

The investigation may begin with the physician’s orders. Attorneys may determine what medications were ordered, when the orders were entered, whether they were changed, how they appeared in the electronic health record, and whether the orders contained unusual or contradictory information.

The pharmacy process may then require examination. Investigators may determine who prepared or dispensed the medication, what container was used, how it was labeled, where it was stored, whether pharmacy verification occurred, and whether medications with substantially different purposes could be confused because of storage or workflow practices.

Attention may then turn to the operating room or procedure area. The investigation may examine who obtained the medication, who prepared it, who verified it, who administered it, whether barcode scanning was available and used, whether an independent verification was required, and whether the drug was compared against the patient’s medication order immediately before administration.

Electronic evidence may become particularly important. Hospital information systems can potentially document medication orders, pharmacy verification, access to automated dispensing cabinets, barcode scans, medication administration, order modifications, and the identities of personnel interacting with portions of the patient’s electronic record.

A serious medication-error case therefore may involve much more than determining who physically administered the drug. The central question can become why the hospital’s layers of safety controls failed to stop the error before the medication reached the patient.

When Does a Medication Error Become Medical Malpractice?

Not every adverse medical outcome constitutes malpractice. Medicine carries unavoidable risks, and a poor outcome alone does not establish negligence.

A medication error may support a Tennessee health care liability claim when evidence demonstrates that a health care provider failed to meet the applicable standard of care and that the failure caused an injury.

Medication malpractice allegations can involve prescribing the wrong medication, dispensing the wrong drug, administering medication intended for another patient, giving an incorrect dose, using the wrong route, administering medication at an unsafe rate, failing to identify a contraindication, or failing to follow required medication-verification procedures.

A hospital may also face allegations involving institutional failures. Depending on the evidence, these could concern medication storage policies, pharmacy procedures, staffing, training, supervision, technology, communication, or failure to implement appropriate safety systems.

Establishing liability requires more than identifying an error. The plaintiff generally must establish causation: that the negligent act or omission caused or materially contributed to the injury for which damages are sought.

In a paralysis case, medical evidence may therefore be needed to determine precisely what caused the neurological injury and distinguish injury attributable to the alleged medication event from unrelated medical conditions or complications.

Tennessee Has a Short Deadline for Medical Malpractice Claims

Potential claimants should pay particular attention to Tennessee’s filing deadlines.

Tennessee Code § 29-26-116 generally provides a one-year statute of limitations for health care liability actions. The statute contains a discovery provision when an injury is not discovered during the initial period, but it also generally imposes a three-year statute of repose, subject to specified exceptions.

Tennessee health care liability cases also involve procedural requirements before and when litigation begins. Tennessee Code § 29-26-121 generally requires 60 days’ pre-suit notice to prospective defendants, while § 29-26-122 establishes certificate-of-good-faith requirements in cases requiring expert testimony.

These procedural requirements make waiting particularly risky.

An attorney needs sufficient time to obtain records, identify potential defendants, investigate the medical issues, evaluate causation, retain appropriate medical professionals when required, satisfy notice requirements, and prepare the lawsuit.

A family should therefore not interpret a one-year limitation period as meaning that nothing needs to happen until the end of that year.

Nashville Hospital Medication Error Lawsuit FAQs

Can I File a Lawsuit If a Hospital Gave Me the Wrong Medication?

Potentially. Giving a patient the wrong medication can support a medical malpractice claim when the error represents a departure from the applicable standard of care and causes injury. The investigation should determine what drug was ordered, what was dispensed, what was administered, who participated in each step, and why existing safeguards did not prevent the error. A patient who experiences paralysis, cardiac injury, neurological damage, organ injury, or another serious complication may potentially seek compensation for the medical and financial consequences attributable to the mistake.

Can the Hospital Be Responsible Even If a Nurse or Other Individual Administered the Medication?

It may be. Liability depends upon employment relationships, the circumstances of the incident, and whether institutional failures contributed to the injury. A hospital medication system involves physicians, nurses, pharmacists, electronic ordering systems, pharmacy controls, storage practices, and medication-verification procedures. A lawsuit may therefore examine both the conduct of individual health care professionals and whether hospital policies, staffing, training, supervision, or medication-safety systems contributed to the error.

What Compensation Could Be Available for Paralysis Caused by a Medication Error?

Compensation may include past and future medical expenses, rehabilitation, therapy, mobility equipment, home modifications, attendant care, lost earnings where applicable, and other economic losses. Damages may also address pain, disability, emotional suffering, and loss of enjoyment of life. Tennessee places statutory limits on noneconomic damages, including a higher limit for certain catastrophic injuries such as qualifying spinal cord injuries resulting in paraplegia or quadriplegia.

How Long Do I Have to File a Tennessee Hospital Malpractice Lawsuit?

Tennessee generally applies a one-year statute of limitations to health care liability claims under Tenn. Code § 29-26-116, with additional rules concerning discovery and a three-year statute of repose subject to statutory exceptions. Tennessee also has pre-suit notice and certificate-of-good-faith requirements that may apply. Because determining the correct deadline can depend on the facts, an injured patient should have the potential claim evaluated promptly rather than waiting until the anniversary of the incident.
