Introduction
The circumstances of the Lindsay Clancy case are unusual, but many of the issues it raises will be familiar to health and social care providers across the world.
For anyone who has not read about the case, in January 2023, Lindsay Clancy, a former labour and delivery nurse in Massachusetts, was accused of killing her three children. Evidence presented during the criminal trial suggests that, in the months before the deaths, Clancy's mental health deteriorated significantly. She received treatment from multiple mental health professionals, was prescribed numerous psychiatric medications over a relatively short period and sought hospital-based mental health care shortly before the incident. These aspects of her care have become a focus of debate about the recognition and management of severe perinatal mental illness. Lindsay Clancy and her ex-husband are bringing civil proceedings against those healthcare providers and professionals.
Her defence argued that she was suffering from postpartum psychosis and was not criminally responsible for her actions, while prosecutors maintained that she acted intentionally. The trial ended in a mistrial after the jury was unable to reach a unanimous verdict.
The case was back before the court on 29 September 2026 where the defence raised the question of whether there is any evidence that she killed her three children. The question of whether Lindsay is re-tried and for what is to be determined.
The case has attracted international attention because of the questions it raises about severe perinatal mental illness, risk assessment and how healthcare services recognise and respond to deteriorating mental health.
Cases involving serious harm often prompt questions about whether risks were recognised quickly enough, whether concerns were escalated appropriately and whether the right information reached the right people at the right time.
Organisations cannot eliminate every risk or predict every tragic outcome. What they can do is make sure their systems are capable of responding when the clinical picture changes.
What leaders in the maternal mental health field should review now
1. How risk is reassessed when new concerns emerge
Many investigations find that the issue is not the initial assessment itself, but what happens afterwards.
Patients do not always follow the course clinicians expect. Concerns from family members, a lack of improvement, or the emergence of new symptoms can all change the assessment of risk. In those situations, organisations need to be confident that risk is continually being revisited and reassessed rather than diagnoses and treatment plans simply being carried forward.
Action: examine whether systems empower clinicians to reassess and document risk when circumstances change and whether governance reviews identify examples where earlier assumptions were not challenged.
2. How family concerns are recorded and acted upon
Family members are often the first people to notice changes in behaviour, mood or functioning. They may identify concerns that are not immediately apparent during clinical appointments and may not know how to raise their concerns or to who.
A common theme identified in patient safety investigations is not that concerns were never raised, but that they were not fully explored, documented or reflected in subsequent decision-making.
Action: analyse whether processes prompt staff to record concerns raised by family members, document what action was taken and explain how those concerns informed clinical decision-making. Include family members at visits and appointments, especially at the post-natal stage.
3. Test information sharing between services
Patients with complex mental health needs frequently receive care from several services at the same time. Problems can develop when information is held across different teams and no one clinician or service has a full view of what is happening.
In many cases the information exists somewhere within the system. The challenge is making sure it reaches the people who need it and influences decision-making at the right time.
Action: review communication and escalation arrangements between maternity services, primary care, mental health services and emergency care providers. Consider how those arrangements would operate in practice if concerns about a patient's mental health were increasing over a short period of time.
4. Access to specialist expertise
Perinatal mental health can be difficult to assess and manage, particularly where symptoms are evolving or a diagnosis remains uncertain.
Clinicians need to feel confident both in recognising when specialist input is needed and in knowing how to access it without delay. NHS England published its Maternal Care Bundle in January 2026. It is described as a care bundle for reducing maternal mortality and morbidity. It contains five elements: venous thromboembolism, pre-hospital and acute care, epilepsy in pregnancy, maternal mental health, and obstetric haemorrhage.
Healthcare providers should ensure the woman is provided with relevant contact details to ‘reach out’ if any concerns, distress or emerging issues arise. As part of routine practice, practitioners should follow up at the next appointment or earlier if needed to confirm that any required referral has been made and appropriate follow-up is in place.
Action: examine referral routes to specialist perinatal mental health services and consider whether staff understand when specialist advice should be sought and how concerns from staff, patients and their families can be escalated if risks increase.
5. Documentation and decision-making
Inquests, regulatory investigations and serious incident reviews often focus on why decisions were made rather than simply whether the outcome was adverse.
Where clinicians have weighed competing explanations, considered risk factors or sought specialist advice, the clinical record should show that.
Action: consider whether records clearly explain the information available at the time, the risks identified, the options considered and the reasons for the decisions that were made.
Conclusion: the governance lesson
For boards, medical directors, senior medics and governance teams working in organisations delivering mental health care to women, the key question is not whether every tragedy can be predicted. It cannot.
The more important question is whether the organisation can demonstrate that concerns were recognised, reassessed as circumstances changed, escalated when necessary and supported by clear clinical reasoning. Those are often the issues that receive the closest scrutiny during the legal processes that follow tragic events including patient safety investigations, inquests and regulatory action.
Cases such as this rarely point to a single failing. More often, they prompt organisations to ask whether their systems would have identified emerging concerns, connected information held by different teams and supported staff to act when risks escalated.
