Ronald Bennett went to a Cape Cod emergency room with shoulder pain. He was told he had rotator cuff tendinitis and cellulitis, given antibiotics, and sent home. He came back two days later in a rapidly deteriorating state. By August 8, 2020, he was dead, killed by septic shock, acute septic arthritis of the left shoulder, metabolic acidosis, and organ failure. He was 58 years old.

His wife Jean, as personal representative of his estate, sued the medical providers who treated him, including nurse practitioner Michael Collins of Cape Cod Orthopedics, alleging they failed to recognize the signs of septic arthritis and act on them in time to save Ronald’s life. The case was thrown out at the malpractice tribunal stage. Last November, the Massachusetts Supreme Judicial Court reversed that dismissal and reinstated the case, finding the tribunal had applied the wrong standard and improperly discounted the plaintiff’s expert opinion.

Bennett v. Collins is a decision worth understanding for any Massachusetts family that has lost a loved one to what appeared to be a mismanaged or misdiagnosed medical condition. I’ve been handling medical malpractice cases on Cape Cod and throughout Eastern Massachusetts for more than 35 years, and cases like Ronald’s are exactly why this area of law matters so much.

What Happened to Ronald Bennett

Ronald presented to the emergency department with shoulder pain. The treating providers diagnosed him with rotator cuff tendinitis and cellulitis, conditions that while painful are not immediately life-threatening, and discharged him with antibiotics. On August 4 and 5, 2020, nurse practitioner Michael Collins saw Ronald and administered fluids and pain medication. Collins advised Ronald to follow up with orthopedics and discharged him again.

Two days later Ronald returned to the hospital in a significantly deteriorated condition. Further evaluation revealed sepsis and septic arthritis of the left shoulder, a joint infection that when unrecognized and untreated progresses rapidly and can become fatal. Ronald suffered cardiac arrest and died on August 8. His death certificate listed septic shock, acute septic arthritis of the left shoulder, metabolic acidosis, and acute-on-chronic renal failure as the causes of death.

What Septic Arthritis is and Why Missing it Matters

Septic arthritis is a bacterial infection of a joint. It is a medical emergency. Unlike rotator cuff problems or soft tissue inflammation, a joint infection left untreated destroys cartilage and bone rapidly and can spread to the bloodstream, causing sepsis and multi-organ failure. The standard of care requires providers to consider septic arthritis whenever a patient presents with joint pain, swelling, warmth, and fever, and to rule it out aggressively through blood work, imaging, and joint aspiration before attributing symptoms to a less serious diagnosis.

The symptoms of septic arthritis can overlap with other more benign shoulder conditions in the early stages, which is precisely why providers are expected to maintain a high index of suspicion and order the appropriate diagnostic workup when the clinical picture is ambiguous. Failing to do so, and discharging a patient with a worsening joint infection on antibiotics that are insufficient to treat it, is a recognized departure from the standard of care. The CDC estimates that sepsis affects more than 1.7 million adults in the United States each year, and a significant portion of those cases involve missed or delayed diagnoses in emergency settings.

Jean Bennett’s expert, Dr. Richman, concluded that Collins failed to promptly order additional imaging studies and blood work, failed to administer appropriate antibiotics, failed to admit Ronald for further treatment, and failed to recognize the symptoms of septic arthritis. Had Collins met the standard of care during the August 4-5 visits, the expert opined, the septic arthritis would have been diagnosed and treated while it was still amenable to cure, and Ronald’s death would have been prevented.

What the Tribunal Did, and What the SJC Said About It

Massachusetts law requires medical malpractice plaintiffs to submit their case to a medical malpractice tribunal under M.G.L. c. 231, § 60B before the case can proceed to trial. The tribunal consists of a judge, a physician, and an attorney. The plaintiff must present an offer of proof, supported by medical records and expert opinion, sufficient to raise a legitimate question of liability appropriate for judicial inquiry. This is a threshold showing, not a full trial on the merits. I’ve written about the tribunal process in more detail in my post on understanding medical malpractice in Massachusetts.

The tribunal found the plaintiff’s evidence against Collins insufficient and dismissed the claims against him. Jean Bennett appealed. The SJC transferred the case from the Appeals Court on its own initiative and reversed.

The court’s opinion, written by Justice Gaziano, identified two fundamental errors in the tribunal’s approach. First, the tribunal improperly discounted Dr. Richman’s expert opinion by treating it as speculative, when in fact the opinion directly addressed the causal link between Collins’s failure to act and Ronald’s death. The SJC noted pointedly that given the nearly two-day gap between when Collins attended to Ronald and when doctors finally performed further imaging and blood work, the conclusion that the septic arthritis would have been diagnosed and treated sooner had Collins met the standard of care was not speculative if the expert’s opinion was properly credited, as it must be at the offer of proof stage.

Second, the SJC found it difficult to reconcile the tribunal’s treatment of Collins with its treatment of the attending physician Bosco, against whom the tribunal did find sufficient evidence even though there was no evidence in the record that Bosco had actually treated Ronald. The court found the inconsistency unjustifiable and indicative of an error in how the tribunal assessed the offer of proof.

The case against Collins was reinstated and will now proceed toward trial.

What This Ruling Means for Massachusetts Malpractice Families

Bennett v. Collins reinforces several principles that matter directly to families who have lost someone to what they believe was inadequate medical care.

The malpractice tribunal is a gatekeeping mechanism, not a trial. Its purpose is to screen out frivolous cases, not to resolve close questions of expert opinion or disputed facts. When a tribunal dismisses a case against one provider while allowing it to proceed against another on identical facts, that inconsistency is grounds for reversal. The SJC was clear that at the offer of proof stage, a credible expert opinion linking a provider’s failure to a patient’s death is sufficient to raise a legitimate question of liability.

Missed diagnoses in emergency settings are among the most common forms of medical malpractice. Conditions including septic arthritis, appendicitis, pulmonary embolism, heart attack, and stroke are frequently misattributed to less serious diagnoses, particularly when patients present with overlapping symptoms. This is a pattern I see regularly in my practice. When a provider fails to consider a dangerous diagnosis, fails to order the tests that would reveal it, and discharges a patient who then deteriorates and dies, that sequence of events is exactly what Massachusetts wrongful death law is designed to address.

Nurse practitioners are held to a standard of care. Collins was a nurse practitioner, not a physician, but that distinction does not reduce the standard of care applicable to his conduct. Under Massachusetts law, healthcare providers including nurse practitioners, physician assistants, and other advanced practice clinicians are held to the standard of care of a reasonably competent practitioner in their field. The SJC’s decision to reinstate the case against Collins reflects that the standard applies fully to mid-level providers.

The Cape Cod connection matters. Ronald was treated at Cape Cod Orthopedics, and his case was filed in Barnstable Superior Court. This is not a Boston teaching hospital case or a distant legal precedent. It is a local family, local providers, and a local courthouse, and it resulted in a statewide ruling that will shape how malpractice tribunals evaluate offers of proof going forward.

What Families Should Know Before the Tribunal

One of the most important lessons of both Bennett and the related DosSantos v. Beth Israel Deaconess Hospital-Milton case decided by the SJC in January 2026 is that the offer of proof stage requires careful, provider-specific documentation. In DosSantos, the SJC affirmed dismissal of a case involving a young woman who developed a perforated appendix after being sent home from the ER with a UTI diagnosis, because the plaintiff’s offer of proof failed to set out specific allegations against each named defendant individually. In Bennett, the same type of error by the tribunal, evaluating the proof too broadly rather than provider by provider, led to the reversal.

The practical takeaway is that building a strong malpractice case in Massachusetts requires expert analysis that addresses the specific conduct of each provider, tied to the specific standard of care applicable to that provider’s role, linked through a clear chain of causation to the harm suffered. That work needs to happen before the tribunal, not after. This is something I pay close attention to from the very beginning of every case I take on, because the offer of proof is often where legitimate claims succeed or fail. You can read more about how Massachusetts deadlines affect your ability to bring a claim at all in my post on the three-year statute of limitations, and about the SJC’s Bellmar ruling on long-term treatment relationships for additional context on how the repose period can affect these cases.

If You’ve Lost Someone to a Missed or Delayed Diagnosis

Ronald Bennett’s family did everything right. They sought care, they followed up, and when things got worse they went back to the hospital. What failed them was not their diligence but the provider who had an opportunity to catch a life-threatening infection and didn’t.

If your family has been through something similar, I want you to know that the law gives you a path forward, and that path is worth exploring even if someone has told you the case is too difficult or too old. Cases that look closed at the tribunal stage can be reopened, as the SJC made clear in Bennett. Cases that look time-barred sometimes aren’t, as the SJC made clear in Bellmar.
