Important Distinctions for the Statute of Limitations in a Medical Negligence Case in Delaware

Defense Digest, Vol. 27, No. 4, September 2021

Key Points:

  • The phrase “injury occurred” in Delaware Code Title 18 Section 6856 means the date when the wrongful act or omission occurred, not when the claimant discovered the act.
  • The continuous negligent treatment doctrine applies in cases where there is a continuum of negligent treatment and the statute of limitations commences on the date of the last act in the negligent continuum.
  • The continuing treatment doctrine applies in cases where there was an initial act of negligent treatment but no negligence “continuum,” but is not recognized in Delaware.
  • Where the injury coincides with the negligence is when the “injury occurred.” But under the unique facts of Anderson, the injury did not arise at the time of negligence, so the Superior Court should make a factual determination regarding when the injury occurred for application of the statute of limitations.

The statute of limitations for a medical negligence case in Delaware is two years, commencing on the date of injury or, alternatively, three years, if the injury is unknown to the injured person and cannot be discovered through reasonable diligence within two years of the injury date. GI Assocs. of Del., P.A. v. Anderson, 247 A.3d 674 (Del. 2021); see also 18 Del. C. § 6856. The Delaware Supreme Court recently discussed two doctrines that inform the determination of when the statute of limitations commences: (1) the continuous negligent medical treatment doctrine; and (2) the continuing treatment doctrine. Anderson, 247 A.3d at 677.

The continuous negligent medical treatment doctrine applies in cases where there was a continuous course of improper treatment so intertwined that it would be illogical to break it up into individual acts of negligence. Ewing v. Beck, 520 A.2d 653, 662 (Del. 1987). The statute of limitations begins on the date of the last negligent act in the continuum of negligent medical care. Thus, a plaintiff is permitted to bring suit for the consequences of the entire course of negligent conduct. However, under the continuous negligent medical treatment doctrine, the plaintiff must allege there was negligence on the date they claim the statute of limitations to have commenced.

By contrast, the continuing treatment doctrine applies in cases where there was an initial act of negligent treatment but no negligence “continuum,” like under the continuous negligent medical treatment doctrine. Under the continuing treatment doctrine, the statute of limitations begins on the date of the last act of treatment related to the initial negligence, regardless of whether or not the last act itself was negligent. Whereas the continuous negligent medical treatment doctrine is limited to the last act in the negligent continuum, the continuing treatment doctrine is more flexible and reaches to the last act in the treatment. Benge v. Davis, 553 A.2d 1180, 1183 (Del. 1989) (citing Ewing, 520 A.2d at 663, n.11). Unlike under the continuous negligent medical treatment doctrine, it does not matter whether negligence continued throughout the entire course of treatment under the continuing treatment doctrine.

Delaware recognizes the continuous negligent medical treatment doctrine, but not the continuing treatment doctrine because “injury occurred” in § 6856 means the date of occurrence, not of discovery. The first Delaware case to address an equitable tolling doctrine in medical negligence cases was Layton v. Allen, 246 A.2d 794 (Del. 1968), where the court held that when an individual sustains an unknowable injury and the harmful effect develops gradually over time, the injury is “sustained” when the harmful effect first manifests itself and becomes physically ascertainable. This open-ended statute of limitations led to a medical malpractice plight, and the Delaware legislature responded by enacting Delaware Code Title 18 Section 6856. In the first case applying the language of Title 18 of Delaware Code Section 6856, Dunn v. St. Francis Hospital, Inc., 401 A.2d 77 (Del. 1979), the Delaware Supreme Court established that under the language of Delaware Code Title 18 Section 6856, “injury occurred” means the date when the wrongful act or omission occurred, not when the act was discovered.

Twenty-one years later in Meekins v. Barnes, 745 A.2d 893 (Del. 2000), the court determined that an act of omission is a valid basis for a medical malpractice claim, but only if that act of omission occurs in the context of another affirmative act, such as failing to diagnose breast cancer at a mammogram appointment. Nine years after Meekins, the court held in Dambro v. Meyer, 974 A.2d 121 (Del. 2009), that the phrase “injury occurred” in Section 6856 refers to the date when the wrongful act or omission occurred, such as the day treatment was delayed and on which a cancer diagnosis could have been made.

In the recent Anderson case, a doctor performed a colonoscopy on the late Mr. William King on April 4, 2011. At a follow-up visit on April 26, 2011, the doctor recommended that Mr. King return for his next colonoscopy in three to five years. Mr. King returned for a colonoscopy within five years—on March 26, 2016—but the colonoscopy could not be completed because a cancerous growth had formed in Mr. King’s colon. He died a few months later. A wrongful death action was filed on April 16, 2018, which claimed that the colonoscopy recommendation that had been made on April 26, 2011, was negligent. Following the doctor’s motion for summary judgment based upon the statute of limitations, the plaintiffs successfully argued that the continuous negligent medical treatment doctrine applied, and the trial court held that the statute of limitations had commenced on March 26, 2016, when the follow-up colonoscopy was performed and the injury was discovered. On appeal, however, the Delaware Supreme Court held that the continuous negligent medical treatment doctrine did not apply because the plaintiffs did not allege negligence in association with the attempted procedure on March 26, 2016.

The court further concluded that the plaintiffs claimed a single act of alleged medical negligence that occurred on April 26, 2011. Under the unique facts in Anderson, the injury did not appear to arise at the time of the alleged breach of the standard of care. Therefore, because Delaware does not recognize the continuing treatment doctrine and the facts in Anderson did not fall under the continuous negligent medical treatment doctrine, the Delaware Supreme Court reversed and remanded to the Superior Court, where the defendants are free to pursue their statute of limitations defense. The Superior Court has been instructed to factually determine the date of injury for purposes of application of the statute of limitations.

No-Cause Jury Verdict Secured in Wrongful Death Trial

We successfully obtained a no-cause jury verdict in a 13-day wrongful death trial. The decedent, a 59-year-old man, was admitted to the emergency room on February 15, 2019, with complaints of abdominal pain, decreased appetite, and constipation, despite the use of laxatives. The patient did not complain of any nausea, vomiting, or diarrhea. He had a significant medical history including diabetes, hypertension, prior coronary artery stenting, morbid obesity (with past gastric bypass surgery), longstanding ventral hernia, and back pain. A CT scan revealed multiple hernias and a potential closed-loop bowel obstruction, leading to a surgery consultation. Our client, an emergency general surgeon, interpreted that the patient did not have a closed loop or any significant obstruction and recommended non-surgical management. The patient was approved to have clear liquids, and had a vomiting incident shortly after, but our client was not notified. The patient was returned to NPO status, and after improving overnight, he was returned to “clears” and additional medical and renal consults were ordered. Our client did not receive any communications from the residents/nurses of any changes in the patient’s condition. On February 18, 2019, two rapid responses were called due to increased heart rate and vomiting. It is believed that the vomiting resulted in aspiration, causing sepsis, ultimately leading to the patient’s death. During the trial, the plaintiff’s sole medical expert highlighted imaging on the wrong hernia, which called into question all of his opinions in the case. We made key objections related to the expert testimony, limiting what the allegations were, and preventing new allegations from being made. After approximately two and a half hours of deliberating, the jury returned a no-cause verdict.

Featured Conversations... Key Takeaways from A.M. Best’s Webinar on the Misuse Defense in Product Liability Claims, Featuring Michael Salvati

Michael Salvati, shareholder in our Philadelphia office, was a panelist for the April A.M. Best webinar, “The Misuse Defense: Strategic Approaches to Defending Product Liability Claims for Insurers.” During the program, Michael and his fellow panelists offered practical, jurisdiction‑specific guidance on how misuse and failure‑to‑warn theories intersect in modern product liability litigation. Michael emphasized the unique challenges these claims present—particularly in states like Pennsylvania, where evidentiary rules diverge sharply from those applied in many other jurisdictions. Failure to Warn as the “Flip Side” of Misuse Salvati explained that failure‑to‑warn allegations often arise as a direct counter to a misuse defense. As he noted, “If our misuse defense is that the plaintiff didn't use a product properly or safely, then the failure to warn claim is that we didn't tell them how to use it properly.” He emphasized that these claims can stem from either the absence of warnings or criticisms of existing warnings, such as insufficient specificity or lack of clarity about risks. Pennsylvania’s Unique Evidentiary Landscape One of Salvati’s most notable points was the stark difference in how Pennsylvania treats evidence of compliance with industry standards. He highlighted that Pennsylvania is “one of the only states…where that evidence is not admissible” in strict liability cases. Manufacturers cannot rely on compliance with ANSI, UL, ISO, or even federal safety standards to defend the product against a strict liability claim—because the focus is solely on the product itself, not the manufacturer’s conduct. Salvati acknowledged the challenge this creates for defense counsel and clients who expect such compliance to carry weight. Understanding the Three Defect Theories Salvati also walked through the three primary defect theories recognized in many jurisdictions: - Design defect – a flaw in the product’s intended design - Manufacturing defect – a deviation affecting a specific unit - Failure to warn – inadequate instructions or warnings He noted that warnings claims are increasingly significant and sometimes stand alone when design or manufacturing theories are weak. As he put it, plaintiffs often default to warnings claims because “the default position seems to be, ‘If I got hurt, there must be something wrong.’” Warranties and State‑by‑State Variations Salvati addressed how breach‑of‑warranty claims fit into the broader framework, explaining that implied warranties—such as merchantability—often overlap with strict liability in Pennsylvania. He emphasized the importance of understanding local nuances, as warranty law and admissibility rules vary widely across states. Looking Ahead: The Growing Importance of Warnings In his closing remarks, Salvati stressed that warnings should never be treated as an afterthought in product liability defense. He observed that warnings‑only claims are becoming more common and urged manufacturers and insurers to continually evaluate the clarity and completeness of their instructions and warnings. His takeaway: “We should always be talking about what are the instructions that come with our products…to bolster a misuse defense.” Listen to the complete webinar here: https://www3.ambest.com/conferences/events/eventregister.aspx?event_id=WEB1074.

The Enforceability of Online Arbitration Agreements Remains Unresolved in Pennsylvania, But the Pennsylvania Superior Court has Provided Substantive Guidance on the Issue

Key Points: The Pennsylvania Supreme Court confirms that an order compelling arbitration is not immediately appealable as collateral orders. The outcome of Chilutti II has generally left the substantive enforceability issues with browsewrap agreements unresolved in Pennsylvania. Until this issue is resolved by the Pennsylvania courts, companies operating in the Commonwealth should strive to ensure that their registration websites and/or application screens conspicuously present arbitration agreements in manners which ensure their users and consumers assent to the terms of the agreements by following the standards set forth in Chilutti I. Browsewrap agreements have been defined as agreements “‘in which a website offers terms that are disclosed only through a hyperlink and the user supposedly manifests assent to those terms simply by continuing to use the website,’ and typically do not require an electronic signature.” See, Cobb v. Tesla, Inc., 2026 WL 458470, at *1 n. 2 (Pa. Super. Feb. 18, 2026) (citation omitted). They are largely regarded as the “if you keep using this, you agree to everything buried in this link” terms embedded into almost every online agreement consumers and users sign before proceeding with purchases of goods and/or services. While consumers are generally aware of them, many almost never click on the link, nor read them in their entirety. This leaves many consumers and users ignorant of the terms and impact of such agreements. However, one’s ignorance of the otherwise neatly-tucked-away terms rarely renders them unenforceable. The issue of the enforceability of browsewrap agreements has been up for debate for some time in many jurisdictions, including Pennsylvania. Indeed, Pennsylvania had a brief grip on this issue for a period in time. Specifically, in 2023, an en banc Superior Court set forth heightened standards for companies to meet in order to secure assent and enforce browsewrap arbitration agreements. See Chilutti v. Uber Techs., Inc., 300 A.3d 430 (Pa.Super. 2023) (en banc) (“Chilutti I”) Chilutti I involved a husband and wife who sued Uber and its subsidiaries after the wife, a wheelchair bound passenger using Uber’s rideshare service, fell, struck her head, and lost consciousness due to her uber driver failing to provide a seatbelt and making an aggressive turn during the trip. The Chilutti’s filed a negligence lawsuit against Uber and its subsidiaries. In response, the defendants moved to compel arbitration, arguing that “the couple’s conduct on the company’s website and application — when they registered for the ridesharing service — signified that they agreed to be bound by the mandatory arbitration provision found in the hyperlinked terms and conditions.” The trial court granted the defendants’ petition and stayed the proceedings pending the results of arbitration, and the Chilutti’s appealed. On appeal, the Superior Court addressed two issues. First, it addressed the issue of whether it had jurisdiction to hear the appeal. A divided Superior Court determined that it did, with its basis for the holding being that the order from which the Chilutti’s appealed was a collateral order. Next, the Superior Court set out to address the merits of the Chilutti’s substantive claim. The Superior Court concluded that the parties lacked a valid agreement to arbitrate. Its rationale was that Uber’s website and application did not provide reasonably conspicuous notice of the terms to the Chiluttis. In reaching this decision, the en banc Superior Court held that browsewrap arbitration agreements are enforceable in Pennsylvania only if the registration website and application screens explicitly inform consumers that they are waiving the right to a jury trial, the registration process cannot be completed until the consumer is fully informed of this waiver, and, when the agreement is available via hyperlink, the waiver appears at the top of the first page of the terms in bold, capitalized text. Since the ruling, Pennsylvania courts have applied Chilutti I to determine if browsewrap agreements are enforceable.  For instance, the Allegheny County Court of Common Pleas invoked Chilutti I to reject an agreement that lacked an express jury-trial waiver on the assent screen.  See Miller v. Festival Fun Parks, LLC, 92 WDA 2025 (C.P. Alleg. Cnty. Mar. 24, 2025). Similarly, the Superior Court has held that notice which failed to explicitly state the consumer was waiving a jury-trial right did not “me[e]t the strict burden set forth by our en banc Court in Chilutti I.” Pierce v. FloatMe Corp., 348 A.3d 1077, 1088 (Pa. Super. 2025). While the issue of enforceability of browsewrap agreements appeared to have been resolved by Chilutti I, Pennsylvania courts’ grip on this issue has been slackened by the Pennsylvania Supreme Court’s January 21, 2026, opinion in Chilutti II. See Chilutti v. Uber Techs., Inc., 349 A.3d 826 (Pa. 2026) (“Chilutti II”). Therein, the Supreme Court did not address the merits of the Chiluttis’ substantive claim, but rather the issue of whether the Superior Court had appellate jurisdiction to immediately review the orders staying litigation pending arbitration. The Court ultimately vacated the en banc opinion on jurisdictional grounds, holding that the Superior Court did not have appellate jurisdiction because the trial court’s order from which the Chiluttis appealed did not qualify as a collateral order and, thus, the Superior Court erred in holding to the contrary and lacked jurisdiction to entertain the merits” of the Chiluttis’ substantive claim. As such, Chilutti II has rendered Chilutti I nonbinding, and the issue of enforceability of online arbitration agreements remains unresolved. However, in light of the fact the Supreme Court did not address or comment on the merits of the Chiluttis’ appeal, Chilutti I is still meaningful. Specifically, it provides guidance as to the standards a company should strive to meet to ensure they have obtained users’ assent so that they are able to enforce online arbitration agreements. Additionally, it may serve as persuasive authority in judges’ evaluations of petitions and/or motions to compel browsewrap arbitration agreements until this particular issue is properly put before our appellate courts.
