Preventing Hospitalizations in Alzheimer's: A Caregiver's Guide to Keeping Your Loved One Safe at Home
Nearly one in four people with Alzheimer's will experience a hospitalization that could have been avoided with the right support. These hospital stays are often triggered by falls, infections, or sudden confusion—not the dementia itself. The good news is that many of these crises can be prevented with simple, proactive steps you can take at home. This guide walks you through the most common causes and gives you concrete strategies to reduce risks, so you can feel more confident and your loved one can stay safer and more comfortable.
Key points
- Nearly 25% of hospitalizations in Alzheimer's are preventable—they are often caused by falls, infections, or delirium, not the dementia itself.
- Infections (especially UTIs and pneumonia) are the top reason for hospitalization in people with severe dementia; falls are the top reason in mild-to-moderate stages.
- Daily monitoring for pain, hydration, and changes in behavior can catch problems early and allow treatment at home.
- A fall-proof home, a 'sick-day' go-bag, and regular primary care visits are your strongest tools for prevention.
- Sudden confusion or agitation is often a medical emergency—call the doctor immediately, don't wait.
- Personalize your approach based on the stage of dementia, living situation, and caregiver role to get the best results.
Why Hospitalizations Happen in Alzheimer's
When a person with Alzheimer's is hospitalized, it is rarely because of the dementia itself. Instead, hospitalizations are usually triggered by complications that arise because of cognitive decline. Research shows that over 85% of people with Alzheimer's have at least one other chronic condition, and they are more than five times as likely to have six or more such conditions compared to older adults without dementia. This combination of frailty, multiple health issues, and impaired judgment makes them vulnerable to events that could be managed at home with the right care.
The most common reasons for preventable hospitalizations include falls, infections (especially pneumonia and urinary tract infections), heart problems, and episodes of delirium—a sudden, severe confusion that can be triggered by illness, medication changes, or even dehydration. In fact, one study found that among people with dementia receiving care coordination, infections accounted for 22% of hospitalizations and falls for 16.5%. For those with severe functional impairment, infections were the top reason, responsible for 30% of hospital stays. These are not random events; they are often predictable and preventable with attentive care.
The Role of Cognitive Impairment in Creating Risk
Cognitive decline changes how a person perceives and interacts with their environment. Someone with Alzheimer's may not recognize a new pain, may forget to drink water, or may not be able to describe symptoms like a fever or a urinary tract infection. This makes it very hard for them to seek help early, and by the time a caregiver notices something is wrong, the condition may have already worsened. For example, a person might not tell you they feel dizzy or weak, which increases their fall risk. They might not notice they are thirsty, leading to dehydration and urinary tract infections.
Additionally, behavioral changes like wandering, restlessness, or agitation can lead to accidents. A person who becomes confused at night (sundowning) may try to get out of bed and fall. Someone who is agitated may pull at a catheter or IV line if hospitalized, which can lead to infections. Understanding that these behaviors are often symptoms of an underlying medical issue—not just 'acting out'—is key to preventing crises. As one expert notes, addressing the causes of behavioral disturbances, such as pain, discomfort, or environmental triggers, is critical to avoiding hospitalizations.
General caregiving information, not medical advice. Check medications and major care changes with your clinician.
Step-by-step
Conduct a daily 'head-to-toe' check for early signs of infection. Each morning, look at skin for redness, warmth, or breaks. Check urine for cloudiness or strong odor (signs of a UTI). Watch for nonverbal cues like grimacing or guarding a body part. If you suspect an infection, call their primary care doctor the same day—early treatment of a UTI can often be managed at home with oral antibiotics.
Create a fall-proof home environment. Remove loose rugs, secure electrical cords, and ensure walkways are clear. Install grab bars next to the toilet and inside the shower. Use nightlights in hallways and the bathroom. Consider a bed alarm or motion-sensor light. If they are unsteady, use a walker or rollator. Have their vision and hearing checked annually.
Keep a 'sick-day' go-bag by the door. Include a list of medications with doses, a copy of their advance directive and healthcare power of attorney, a one-page doctor's note explaining their dementia diagnosis and baseline behavior, plus a familiar comfort item like a blanket. Grab this bag if you go to the ER—it helps staff understand what is normal for them and reduces their anxiety.
Watch for delirium every day. Delirium is a sudden change in attention and awareness—often more dangerous than gradual dementia. Look for new confusion, drowsiness, or agitation worse than usual. Common triggers include infections, dehydration, pain, constipation, or a new medication. Call their doctor immediately—delirium is a medical emergency that requires treating the underlying cause.
Prevent dehydration by offering small sips of water or other fluids every hour. Use a colorful cup or straw to make drinking easier. Offer hydrating foods like watermelon or soup. Dehydration is a leading cause of UTIs and constipation, which can cause pain and confusion.
Manage pain proactively because people with Alzheimer's often cannot tell you they are in pain. Look for restlessness, pacing, grimacing, or appetite changes. Offer acetaminophen as directed by their doctor, or try non-drug approaches like a warm compress or gentle massage. Untreated pain can lead to agitation, falls, and even pneumonia from shallow breathing.
Schedule primary care visits every three to six months, even when things seem fine, and use those appointments to review every medication. Ask the doctor to look for 'anticholinergic' drugs that can worsen confusion. A proactive primary care team who knows your loved one well is your best defense against preventable hospitalizations.
Supervise meals and watch for swallowing problems, because difficulty swallowing can silently cause aspiration pneumonia. Ensure they are sitting fully upright during meals and for 30 minutes after. Offer smaller bites. Ask the doctor or a speech therapist whether liquids should be thickened. Watch for coughing, choking, or a wet-sounding voice during eating, and ask for a swallowing evaluation if you notice these signs.
What not to do
Do not assume a fall is 'just a fall' and move on. A fall can signal an underlying infection, medication side effect, or new weakness. Even if they seem fine, check for head injury, watch for delayed confusion, and report the fall to their doctor within 24 hours.
Do not skip or delay doctor visits because 'they seem fine.' Many chronic conditions have no obvious early symptoms, and regular check-ups catch them before they become emergencies. Keep appointments on the calendar.
Do not try to 'tough out' a fever or sudden new confusion at home. These are red flags for serious infection or a life-threatening condition like sepsis. Call the doctor right away or go to urgent care—do not wait until the next day.
Do not use physical restraints or sedatives to prevent falls. Restraints increase agitation, muscle weakness, and fall risk; sedatives can worsen confusion and unsteadiness. Instead, adjust the environment (lower bed, add floor mats, use bed alarm) and look for the root cause of restlessness.
Do not dismiss sudden behavioral changes as 'just the dementia.' A new spike in agitation, wandering, or aggression is often a medical signal—UTI, pain, constipation, or medication reaction. Investigate the cause promptly.

Discuss with your clinician
Ask your doctor: 'What is the best way to treat a suspected UTI at home without going to the hospital? Can we have a standing order for a urine culture and antibiotics?'
Ask your doctor: 'Is my loved one a candidate for a do-not-hospitalize (DNH) order or a palliative care consult to avoid unnecessary ER visits?'
Ask your doctor: 'Are any of their current medications increasing fall risk or causing confusion? Can we reduce or stop any of them?'
Ask your doctor: 'What are the early signs of pneumonia or sepsis I should watch for at home, and when should I call you versus going to the ER?'
Ask your doctor: 'Can we create a plan for managing pain at home, including which over-the-counter medications are safe and at what doses?'
