Pain is something many people experience, and for those with dementia, it can be even more complex. This is partly due to age-related health issues like arthritis and other long-lasting problems. The challenge here is that when someone has dementia, it can be hard for them to communicate what kind of pain they are in. This makes it difficult for doctors to figure out how much pain these patients really feel.

One common way to manage pain is through Opioids. These medications are often given for moderate to severe pain. However, giving opioids to older people can come with a lot of risks, such as trouble breathing, falling, feeling sleepy, or becoming confused. These risks can be especially high when starting the medication, which is a big concern for dementia patients who may not be able to explain their symptoms clearly.

Because dementia patients are in such a vulnerable position, several studies have looked at what happens when they use opioids. One study found that people who used opioids for the first time had a higher chance of breaking their hip. Another study found that those taking opioids were more likely to get pneumonia, a serious lung infection. More recent research looked at patients in Denmark and found a higher risk of death within six months for those who started taking opioids compared to those who hadn't.

The Aim of the Study

This study set out to find out how starting opioids affects short-term mortality, or death, among dementia patients. The researchers compared people who started taking opioids after being diagnosed with dementia to those who had already been taking them before their diagnosis. They wanted to see if having experience with opioids made a difference in how these patients fared.

To make sure the results were as accurate as possible, they focused on people who had at least three medical check-ups both before and after their dementia diagnosis. This way, they could ensure these individuals were getting consistent care.

Study Setting and Population

The research was done at Stanford Health Care Alliance, an integrated health system with multiple locations. They looked at data from a large number of individuals who had seen a doctor between 2015 and 2024. From this group, they identified those with a diagnosis of dementia or mild cognitive impairment (MCI), which can be a precursor to dementia. Ultimately, they focused on individuals aged 50 to 100 and made sure to exclude those who died shortly after surgery, as this could affect the study's findings.

The final group included about 27,759 people with dementia or MCI. Of these, about half had used opioids after being diagnosed. Some of them had taken opioids before their diagnosis, while others started after. The researchers wanted to compare these two groups.

Measuring Outcomes

The main focus of the study was short-term mortality, specifically looking at death within 14 days of starting opioid treatment. They also monitored deaths up to 60 and 180 days after starting treatment. To get the death dates, they used their electronic health records and statewide death records, ensuring they captured as many deaths as possible.

The researchers divided opioid users into two groups: those who were new to opioids and those who were consistent users. This distinction was important because opioids are often prescribed for existing health issues, which could complicate the results.

Uncovering Patient Characteristics

The study gathered a lot of information about the patients' health before they started taking opioids. This included their age, race, body weight, insurance status, existing Health Problems, and medication use. By looking at these factors, the researchers could get a clearer picture of how opioid use affected different groups of patients.

They focused on health issues known to be linked to both dementia and the risk of death, such as heart problems, lung diseases, and various other conditions. They also took note of medications that could impact the patients’ health or that were specifically recommended for dementia treatment.

Analyzing Data

The researchers compared the characteristics of both new users and consistent users of opioids. They used statistical tests to see if there were any meaningful differences between the two groups. This helped them understand if starting opioid treatment had different effects based on prior experience with the medication.

Additionally, they employed a model to calculate the risk of death for new users within the first 14 days. This model helped them see how different health factors influenced the likelihood of mortality.

Key Findings

One of the most significant findings was that those who were new to opioids had a much higher risk of dying within the first two weeks compared to those who had been taking them for a while. This heightened risk was particularly marked among those using strong opioids like morphine or fentanyl. For dementia patients specifically, the risk was even higher.

Interestingly, the risk of death started to even out by about 51 days after beginning treatment. This means that after the initial period, the disparity in mortality rates between new and consistent users became less pronounced.

Among those who died soon after starting opioids, many experienced respiratory issues, particularly pneumonia. This raised questions about whether new opioid use contributed to these complications or if patients already had underlying problems that were exacerbated.

Causes of Mortality

To understand what caused the deaths within the first two weeks, researchers reviewed clinical notes from patients who passed away. They used advanced tools to identify common health problems mentioned shortly before death. This analysis revealed that respiratory issues were frequently cited, especially pneumonia, which was more common among new opioid users.

The researchers also looked at patients who had pneumonia before starting opioids. They found a significant link between having pneumonia and a higher risk of dying shortly after starting opioid treatment. However, for those without pneumonia, starting opioids did not seem to increase the risk of developing pneumonia.

Conclusion

The results of this study suggest that starting opioid treatment after a dementia diagnosis can be linked to a higher short-term mortality risk. This risk is especially concerning within the first two weeks of starting the medication. Given these findings, it's crucial for healthcare providers to closely monitor patients during this critical period and consider alternative pain management strategies when possible.

By combining electronic health records with information from death records and analyzing unstructured clinical notes, the researchers were able to gain a more comprehensive view of the situation. This has important implications for how healthcare for patients with dementia is managed, particularly regarding pain management decisions.

Ultimately, for caregivers and medical professionals, this study serves as a reminder to tread carefully when it comes to pain management in dementia patients, especially when considering opioid treatment. Ensuring that these vulnerable individuals receive the best possible care allows for a more thoughtful approach to managing pain while minimizing risks.

Title: Short-Term Mortality Risk in Dementia Patients Initiating Opioids: A Retrospective Cohort Study Comparing New Users and Consistent Users

Abstract: ImportanceThe opioid epidemic continues to grow, and while the adverse effects of opioids are well-known, their impact on short-term mortality in patients with dementia or mild cognitive impairment (MCI) remains understudied, despite the high vulnerability of this population. ObjectiveTo evaluate the short-term mortality risk associated with initiating opioids in patients diagnosed with dementia or MCI DesignRetrospective observational cohort study SettingMultisite healthcare system in Northern California ParticipantsHealth records of 27,759 patients aged 50-100 with dementia or MCI, with encounters between January 1, 2015, and July 31, 2024. Exclusions included patients who died within 14 days of surgery, had fewer than three clinical encounters before and after diagnosis, or were first diagnosed with dementia/MCI at death. ExposuresInitial opioid use following dementia or MCI onset. Patients were categorized as new users (no opioid use in the prior year) or consistent users (prior opioid exposure). Main Outcome and MeasuresShort-term mortality risk, defined as death within 14 days of first opioid exposure, with additional monitoring up to 60 days after opioid initiation. Hazard ratios were calculated using Cox proportional hazards regression, adjusting for demographics, comorbidities, and medication exposure. We used GPT.3.5-Turbo to identify possible causes of death from unstructured clinical documentation, supplemented by data from California public death records. ResultsAmong 14,107 patients prescribed opioids following the onset of dementia/MCI onset, 9444 were new users and 4663 were consistent users. The cohort was predominantly female (56.0%), with a median age of 81 years (IQR:73-87). New users exhibited a 1.95-fold (95% CI, 1.55-2.46; P < 0.0001) increased risk of mortality within 14 days of initial opioid exposure compared to consistent users. Respiratory illnesses were more prevalent among new users who died within 14 days after opioid exposure (62% vs. 48%, P
