You get a phone call from your mother, who is old. Yesterday she was completely clear, but today she is suddenly confused, angry, and not making any sense. It's a scary time full of worry. Is it a stroke? Is it the quick start of dementia? Delirium is a common cause of this sudden change in mental status, and it is a medical emergency. A quick response to find and fix the root cause is the key to a good outcome. Direct Primary Care (DPC), which focuses on immediate access and a deep understanding of patients, is the most important "first alert system."
Delirium is a sudden and changing problem with a person's attention, awareness, and thinking. It is a sign of a serious brain problem and is always a sign of a physical problem.
Dementia is NOT delirium: This is one of the most important differences in medicine.
Delirium: It comes on suddenly (over hours to days), it gets worse at night (sundowning), and it can usually be treated once the cause is found.
Dementia: It starts slowly (over months to years), gets worse slowly over time, and can't be stopped. A person with dementia often gets delirium on top of it, which makes their usual confusion worse all of a sudden.
The underlying cause is very important: Your body's "check engine light" is delirium. Older adults often have treatable causes like:
Infections, particularly urinary tract infections (UTIs) and pneumonia.
Not drinking enough water or having an electrolyte imbalance.
Side effects from drugs, especially new ones or those that block acetylcholine (like some allergy or bladder medications).
Very bad constipation.
A recent hospital stay or surgery.
Warning: Delirium is a medical emergency. The main goal is to quickly find and treat the underlying cause, which may mean going to the ER or staying in the hospital. DPC's most important job is to help with prevention, early detection, and quick triage. Here's why DPC is the best way to take care of patients who are at risk of delirium:
A quick response to sudden confusion: In an active case, this is DPC's most important job.
Access Right Away: A DPC doctor can see a family member right away over the phone, in person, or in the office on the same day if they call about their loved one's sudden confusion.
Expert Triage: Your doctor can quickly figure out what's going on. They can start an urgent workup (like a STAT urinalysis in the office) and tell you where to go for care (home treatment vs. the ER) with specific instructions, saving you time and getting treatment started faster.
The Power of Prevention for Adults Who Are at Risk: The best way to deal with delirium is to stop it from happening in the first place. DPC's continuity is very important.
Careful Medication Management: Your DPC doctor has time to look over your elderly loved one's full list of medications on a regular basis and "de-prescribe" or change any drugs that are known to make delirium more likely.
Proactive Care for Chronic Diseases: Your DPC doctor lowers the risk of getting sick and having a delirium episode by keeping conditions like diabetes and heart failure under control.
A focus on non-drug strategies and teaching families: Your DPC doctor is like a coach for dealing with delirium.
The Best Way to Treat: They can teach your family the best, evidence-based ways to care for a loved one who is delirious. These include giving them frequent reorientation (using clocks and calendars), making sure they have their glasses and hearing aids on, keeping a normal sleep-wake cycle, and encouraging them to drink and eat well.
Avoiding Harmful Medications: They will help you stay away from sedatives, which can make delirium worse.
Case 1: David's son, who is 88 years old, calls their DPC doctor in a panic because his father, who has mild dementia, is suddenly very upset and confused. The doctor makes an appointment to see the patient right away. A quick urine test done at home shows that the person has a bad UTI. The doctor gives an initial dose of an antibiotic and sets up home health services. This successfully treats the cause of the delirium and stops a chaotic ER visit and hospital stay.
Case 2: Linda, who is 82 years old, is brought to her DPC doctor by her daughter. The doctor, who sees Linda often and knows her cognitive baseline well, notices that she is more sleepy and inattentive than usual. A careful look at her medications shows that a different specialist recently put her on a new medicine for an overactive bladder. The DPC doctor stops the medicine because he knows it could cause delirium. Linda's mental state returns to normal over the next 48 hours, reversing the delirium caused by the medication.
Q: My dad has dementia and gets more confused at night ("sundowning"). Is that crazy? A: It might be. It is common for people with dementia to experience sundowning, but a sudden and big change in their usual pattern of confusion is a big sign that they may have delirium on top of their dementia. It is always a good idea to have a checkup to see if there is a new, underlying medical problem, like an infection. The best person to help you make this difference is a DPC doctor who knows your father's baseline.
Q: Shouldn't I give my upset loved one a sedative to help them calm down? A: Not usually, if it can be avoided. It is clear that for most cases of delirium, sedating drugs can make the confusion and agitation worse and can cause other problems, like falls. Experts say that the best and safest way to go about things is to use non-drug methods first and then aggressively treat the medical problem that is causing the symptoms.
Q: How can DPC help if my mom is already in the hospital with delirium? A: Your DPC doctor can be a strong supporter. They can talk to the hospital staff and give them important information about your mom's baseline cognitive function, which the hospital staff can't know. They can also help make sure she has a safe and effective discharge plan with close follow-up so she doesn't get another delirium and have to go back to the hospital right away.
DPC is a clear benefit for older adults and their families because it has a "First Alert System." DPC's quick access is important for spotting and sorting out delirium early on, which is a real medical emergency.
Being great at prevention: The DPC model's focus on continuity and careful, proactive medication management is the best way to keep older adults who are at risk from getting delirium.
Putting Person-Centered, Non-Pharmacologic Care First: The time and philosophy of DPC fit perfectly with the evidence-based, supportive strategies that are the most important parts of good delirium management.
When an older loved one suddenly gets confused, it's not just a sign of "old age." It's a medical emergency that needs to be dealt with right away to find and fix the cause. Direct Primary Care provides the vigilant, accessible, and compassionate partnership you need to prevent delirium when possible and to act decisively when it occurs, protecting the safety and well-being of the people you love most.
