One of the most important roles is to detect and manage in terminally ill geriatric patients with dementia. These patients are often at higher risk for due to their weakened immune systems, underlying health conditions, and limited mobility. Detecting infections in these patients can be challenging due to their limited communication abilities and other cognitive and physical impairments. However, early detection and management of infections can significantly improve the patient's quality of life and potentially prolong their life.

Signs and Symptoms of Infection

Sometimes, older people who have dementia get sick from germs that make them have an infection. An infection is when germs get inside your body and make you feel bad. It is important to know when someone has an infection, so they can get the appropriate medicine and feel better. But it is not easy to tell when someone with dementia has an infection, because they may not act like other people who are sick. They may not have a fever or say they are in pain. Here are some things to look for that may mean someone with dementia has an infection:

  • They act differently than usual. They may be more angry, sad, scared, or quiet than normal. They may not remember things well or get confused easily. They may not know where they are or what time it is. This is called a change in behavior or mental status.
  • They have trouble eating or drinking. They may not feel hungry or thirsty, or they may forget to eat or drink. They may lose weight or get dehydrated. This is called a loss of appetite.
  • They feel very tired or weak. They may not have energy to do things they usually do, like walking, talking, or playing. They may sleep more or have trouble staying awake. This is called increased fatigue or weakness.
  • They have trouble moving or walking. They may not be able to stand up, sit down, or balance well. They may fall down or hurt themselves. They may need help to move around or use a wheelchair. This is called decreased mobility or difficulty walking.
  • They feel hot or cold. They may have a high or low temperature that is not normal for them. They may sweat a lot or shiver. They may need more or less clothes or blankets than usual. This is called a fever or chills.
  • They breathe fast or hard. They may have trouble breathing or feel like they can't get enough air. They may cough or wheeze. They may have pain in their chest or throat. This is called rapid heart rate or breathing.
  • They have red, swollen, or warm skin. They may have a rash or a sore on their skin that looks infected. They may have pus or blood coming out of the sore. They may have pain or itching in the area. This is called skin redness, swelling, or warmth.
  • They have pain or in a specific area. They may have a headache, a stomachache, a toothache, or an earache. They may have pain in their back, joints, or muscles. They may have trouble peeing or pooping. They may cry, moan, or groan when they are touched or moved. This is called pain or in a specific area.
  • They have changes in urine color, smell, or frequency. They may pee more or less than usual, or at different times of the day or night. They may have trouble peeing or holding it in. They may have blood or pus in their pee. They may have pee that is dark, cloudy, or smelly. This is called changes in urine color, smell, or frequency.

It is important to note that not all patients may display all these symptoms, and some may not display any symptoms at all. Therefore, it is crucial to monitor these patients closely and look for any changes in their behavior or physical condition.

Preventing Infections

Prevention is key in managing infections in geriatric patients with dementia. Some simple measures can be taken to reduce the risk of infection, such as:

  • Washing hands regularly and using hand sanitizer. This can help get rid of germs that can make you or the person you are caring for sick. You should wash your hands before and after touching the person, before and after eating, and after using the bathroom. You should also use hand sanitizer when you can't wash your hands with soap and water.
  • Thoroughly cleaning and sanitizing equipment and surfaces. This can help prevent germs from spreading to other people or things. You should clean and sanitize any equipment or tools that you use to care for the person, such as thermometers, blood pressure cuffs, or stethoscopes. You should also clean and sanitize any surfaces that the person touches, such as tables, chairs, bed rails, or doorknobs.
  • Encouraging the patient to drink plenty of fluids. This can help keep the person hydrated and flush out toxins from their body. You should offer the person water, juice, soup, or other drinks that they like. You should also watch for signs of dehydration, such as dry mouth, sunken eyes, or dark urine.
  • Ensuring proper hygiene and cleanliness during toileting and incontinence care. This can help prevent infections in the urinary tract or the skin. You should help the person use the toilet or change their diapers as often as needed. You should also clean their genital and anal areas with warm water and soap, and dry them gently. You should use gloves and disposable wipes when handling urine or feces, and throw them away in a sealed bag.
  • Providing adequate nutrition and hydration. This can help boost the person's immune system and fight off infections. You should give the person healthy and balanced meals that include fruits, vegetables, grains, protein, and dairy. You should also avoid giving them foods that are too spicy, salty, or sugary, as they may irritate their stomach or mouth. You should also make sure the person has enough water or other fluids to drink with their meals.
  • Ensuring that wounds are meticulously cleaned and dressed. This can help prevent infections in the skin or the blood. You should clean any cuts, scrapes, or sores that the person has with warm water and soap, and apply an antibiotic ointment. You should also cover the wound with a clean bandage and change it every day or as directed by a doctor. You should also watch for signs of infection, such as redness, swelling, pus, or fever.
  • Encouraging mobility and exercise to maintain strength and mobility. This can help prevent infections in the lungs or the muscles. You should help the person move around and do some physical activities that they enjoy, such as walking, stretching, or dancing. You should also help them breathe deeply and cough to clear their lungs. You should also avoid letting them sit or lie down for too long, as this may cause fluid to build up in their lungs or legs.
  • It is also essential to ensure that no visitors or caregivers are showing any signs of illness and are following proper infection control measures. This can help prevent infections from spreading to the person or others. You should ask anyone who wants to visit the person to stay away if they have a fever, cough, sore throat, or other symptoms of illness. You should also ask them to wear a mask, wash their hands, and avoid touching the person or their belongings. You should also follow the same rules if you are feeling sick or have been exposed to someone who is sick.

Managing Infections

If an infection is suspected, prompt management is essential. This may involve collecting samples for cultures and starting appropriate antibiotic treatment if necessary. It is important to work closely with the patient's physician to determine the best course of treatment based on the patient's overall health and medical history. In some cases, it may be necessary to hospitalize the patient for more intensive treatment.

It is also important to manage any pain or discomfort associated with the infection. This may involve using interventions, such as positioning or massage, or medications such as acetaminophen or opioids.

It is not easy to tell when someone with dementia has an infection, because they may not act like other people who are sick. They may not have a fever or say they are in pain.
