Why Are Seniors At Risk For Utis

Mayo Clinic Minute: Treating Urinary Tract Infections

Men and women older than 65 are at greater risk for UTIs. This is because both men and women tend to have more problems emptying their bladder completely as they age, causing bacteria to develop in the urinary system.

In older men, this often happens because of a common condition called benign prostatic hyperplasia , or an enlarged prostate gland. The enlarged prostate blocks the flow of urine and prevents the bladder from fully emptying.

Other risk factors for UTIs in older adults include:

  • Using a catheter to empty the bladder
  • Having kidney stones, which can block the flow of urine
  • Having a suppressed immune system, which lowers the bodys defense against infection

Epidemiology Of Urinary Tract Infection

Both ASB and UTI are common among older adults. UTI is the second most common infection diagnosed in the acute hospital setting,6 and accounts for almost 5% of all emergency department visits by adults aged 65 years and older in the United States each year.7 In long-term care facilities, UTI accounts for approximately 30% to 40% of all health careassociated infections, with an estimated point prevalence of 1.5% to 1.64%.8,9 In community-dwelling older adults, the incidence and prevalence of UTI varies with age and gender. The incidence of UTI ranges from 0.07 per person-year in postmenopausal women10 to 0.13 per person-year in adults older than 85.11 The prevalence of UTI in one cohort study in women older than 65 years was found to be approximately 16.5% over a 6-month period.12 Another cohort study in women older than 85 found almost 30% of women to have reported at least 1 UTI within a 12-month period.13 In men, the annual incidence of UTI ranges from 0.05 in men aged 65 to 74 years and is estimated to increase to 0.08 in men aged 85 and older.14 Although UTI is one of the most commonly reported infections in older adults, definitions for symptomatic UTI vary significantly across the literature, making the reported incidence and prevalence of symptomatic UTI in this population variable.

How The Urinary Tract Works

Urine is made by your two kidneys, one on each side of the tummy . Urine drains down tubes called ureters into the bladder. There it is stored and passed out through a tube called the urethra, when you go to the toilet.

In the average adult patient there should be a urine output of: 0.5-1 ml/kg/hr. This means that an average 70 kg man should produce 35-70 mls an hour. However urine output decreases in older patients and the target urine output should be 0.25-0.5 ml/kg/hr. This means that a 70 kg man who is aged over 65 years should produce 17.5-35 mls per hour.

The challenge of developing guidelines for the diagnosis, management, treatment, and prevention of urinary tract infections is a daunting one. The condition runs through diverse populations of the elderly, from the walking well to the chronically ill. Each population has unique characteristics and requires a tailored approach to diagnosis and treatment.

In this article, the discussion of UTIs has been structured according to walking-well, chronically ill, and institutionalized elderly patients in order to better elucidate the issues associated with each population.

Results Of Individual Studies

Among the included studies, the rate of confusion in patients with suspected UTI was most commonly reported followed by the rate of suspected UTI in patients with confusion . Some studies reported the rate of confusion in patients with bacteriuria and one study reported the rate of bacteriuria in patients with confusion. The majority of studies reported confusion as delirium , followed by a few reporting confusion , altered mental state , and mental status changes , with one study reporting both delirium and altered mental status . Twelve studies analysed the correlation between suspected UTI or bacteriuria and confusion .

Can Uti Cause Permanent Dementia

There is no definitive answer to this question as the research on the matter is inconclusive. Some studies suggest that there is a link between UTIs and dementia, while other studies are not able to confirm this connection. It is possible that UTIs may contribute to the development of dementia, but further research is needed to determine if this is truly the case.

When bacteria enter the urethra through the urethra, they infect the bladder and kidneys, causing UTIs. Infection can cause serious health problems if left untreated. Urinary tract infections are commonly accompanied by fever, chills, or lower back pain. Despite this, dementia patients rarely succeed. UTIs can aggravate dementia symptoms, but they are not always indicative of dementia. Falls, recent incontinence, or a loss of appetite are all possible symptoms of a UTI infection. If left untreated, the infection can become life-threatening and spread to the blood stream.

Diagnosis And Management Of Urinary Infections In Older People


Urinary tract infection is common in older people

Older people presenting non-specifically are often incorrectly diagnosed as having a UTI

Asymptomatic bacteriuria is common in frail older people and should not be treated

There is no reliable diagnostic test for UTI

The antibiotic chosen to treat UTI should have as narrow spectrum as possible and be prescribed for the shortest effective duration

Older adults are more prone than younger individuals to developing urinary tract infections for several reasons, including:

  • incomplete bladder emptying

  • higher rate of catheter use

  • increased susceptibility to infection associated with frailty.

A sudden decline in physical and/or cognitive function in older people is usually ascribed to a UTI, yet this commonly adopted clinical practice is not supported by the research evidence.

Uti Causes And Risk Factors

Urinary Tract Infection – Overview (signs and symptoms, pathophysiology, causes and treatment)

The most common cause of a UTI in the urethra is a sexually transmitted disease. Chlamydia and gonorrhea are two STDs that can cause a UTI. STDs are also the most common cause of UTIs in younger men.

Prostate problems can also cause UTIs. An enlarged prostate is common in older men and can block the flow of urine. This can increase the odds that bacteria will build up and cause a UTI.

Prostatitis, which is an infection of the prostate, shares many of the same symptoms as UTIs.

Diabetes and other medical issues that affect your immune system can also make you more likely to get a UTI.

Why Do Utis Affect Older People Mentally

You can explain this as part of normal aging because your immune response changes over time. According to Dr. Pearson, any type of stress, physical or emotional, can cause an older adult to become confused.

Delirium From A Uti Can Worsen Quickly: Get Prompt Medical Attention

Antibiotics can be used to treat UTIs, which are common. When someone is experiencing delirium from UTI, their condition may quickly deteriorate. When someone is inrium, they are unable to comprehend what is happening around them and can engage in dangerous behaviors. If a person is suffering delirium as a result of their UTI, their condition can quickly deteriorate. If you or a loved one is experiencing delirium from a UTI, the best thing you can do is seek medical attention as soon as possible. It is critical that patients receive prompt treatment in order to improve their condition and prevent the infection from spreading.

Use Of A Urinary Catheter

Urinary catheters are used to help alleviate the symptoms of urinary retention and urinary incontinence, both of which increase the likelihood of getting a UTI. Unfortunately, the use of urinary catheters can also increase the chance of getting a UTI since, if not properly sanitized, it can introduce unwanted bacteria into your organs.

Strengths And Limitations Of The Review

The strengths of this review are mainly due to its methodological quality that it utilised a broad search strategy, with no limits to age or date applied. This allowed for studies that were representative of an elderly population and without the explicit aim of reporting the relationship between confusion and UTI to be identified. Another strength of this review was the registration of a protocol with pre-specified objectives and methods. The use of a second reviewer independently assessing the quality of selected studies also increases the quality of the review. Limitations included limiting articles to English and being unable to assess the eligibility of the unobtainable full-texts. This review also did not attempt to include studies from the unpublished literature, introducing possible publication bias.

How To Prevent Utis In Seniors

SAPG suspected UTI in older people guideline

Older adults can help prevent UTIs by drinking plenty of fluids to flush the bacteria from their systems, Forciea says. She recommends older adults drink four to six 8-ounce glasses of water a day. Forciea further notes that drinking cranberry juice or taking cranberry tablets also can make urine less inviting for bacteria.

Use these strategies to help prevent UTIs in elderly women:

  • Urinating promptly after the urge arises
  • Wiping front to back

What Happens If A Uti Goes Untreated For An Older Person

UTI infections that go untreated can spread from your bladder to your kidneys and beyond. Especially in older adults or anyone with a lowered immune system, treating an infection earlier can keep it from spreading and overwhelming your system.

An infection that goes untreated can lead to , a serious form of infection. Dr. Slopnick says fear of sepsis is what causes some people to worry about asymptomatic bacteriuria. If you have a UTI, youll almost certainly show symptoms long before the infection spreads or sepsis sets in.

Avoid Antibiotics When You Can

Unnecessary antibiotics dont offer any benefits. You should not take antibiotics for bacteria in the urine if you dont need to.

Antibiotics can kill friendly germs and help drug-resistant bacteria to grow. Resistant bacteria cause illnesses that are harder to cure and more costly to treat. To treat them, a doctor may have to try a few different antibiotics. This increases the risk of serious side effects.

Tests And Treatments For Utis In Older People

UTIs are infections of the urinary tract. The main symptoms of UTIs are:

  • A burning feeling when you urinate
  • A strong urge to urinate often

Bacteria cause most UTIs. Doctors usually treat UTIs with antibiotics, which are strong medicines that kill bacteria.

Older adults are often tested for UTIs, especially in nursing homes. But if you dont have symptoms, urine tests are not very useful. The tests can lead to unnecessary treatments that can even be harmful. This is especially true in older adults. Heres why:

Out of hospital management of UTIs in elderly patients

UTIs are a bacterial infections that can be a huge problem for senior health. Not only do they cause some very annoying and painful symptoms, but they can also lead to much more serious symptoms.

While UTIs in young people do not cause dementia-like symptoms, the fact that UTIs do often bring about these symptoms in the elderly means that you or your family or loved ones need to take extra care to avoid UTIs or treat UTIs as soon as possible.

Can Uti Cause Confusion In Young Adults

The UTI may be to blame if the person has a sudden and unexplained change in behavior, such as increased confusion, agitation, or withdrawal.

Complications are a common symptom of an urinary tract infection . It is a condition in which one is confused for an extended period of time. Dementia, on the other hand, is a progressive mental illness that affects people over time and causes them to lose their memory and intelligence. According to some researchers, UTIs and delirium do not have a direct relationship. Delirium is thought to be the only symptom of a UTI in older people. If a bedbound or dementia patient is having difficulty urinating or is frequently urination, it can be difficult for caregivers to tell if they are bedbound or dementia patient. The provider will try to determine the source of delirium in order to confirm the diagnosis.

Feline Urinary Tract Disease Urinary Issues

FLUTD in cats is a collection of urinary tract conditions that affect cats bladders and urethra. When cats with FLUTD urinate, they experience difficulty and pain, as well as increased urination frequency and blood in their urine.

Your cat may experience pain, loss of bladder control, or a life-threatening emergency as a result of feline urinary tract disease. In Greensboro, veterinarians explain disease symptoms, causes, and treatment options. In overweight, middle-aged cats and those who lack access to the outdoors, urinary tract disease is commonly diagnosed. Because urinary issues in cats may be complex and serious, the first step should be to consult a veterinarian. If left untreated, urinary problems can cause your dogs urethra to become partially or completely obstructed, which prevents him from urinating. Consuming too much urine can cause kidney failure or bladder rupture in a hurry.

Urine Tests Usually Dont Help If You Dont Have Uti Symptoms

Older people often have bacteria in their urine, even if they have no urinary symptoms. This is true for nearly half of all nursing home residents.

Doctors will often order a urine test if an older adult has vague symptoms, such as increased confusion, irritability, or falling. The test will probably show some bacteria. This may lead the doctor to order an antibiotic.

But if the bacteria is in the urine and not causing a real infection, the antibiotic wont help the vague symptoms. There are many other reasons why an older adult might be confused or irritable, or fall.

Why Is Male Urinary Tract Infection Rare

Urinary Tract Infection

There is a lower risk of urinary tract infections in men, all thanks to the male anatomy. A mans urethra is relatively longer as compared to that of a woman. This feature helps keep the bacteria at bay. The more extended passageway makes it difficult for the bacteria to travel inside and infect the bladder. It allows the immune system to take action immediately and wash out the bacteria.

Utis Secondary To Chronic Disease

Diabetes Mellitus: UTIs affect millions of people each year and are responsible for billions of dollars in health care spending. Elderly people with diabetes are thought to be at increased risk for UTIs, presumably secondary to immunologic, neurologic, or anatomical abnormalities.19 In the geriatric population, there is a fivefold increase in a diabetic patients susceptibility to UTI complications. Risk factors include duration of diabetes, high glycosylated hemoglobin level, glycosuria, and pyuria.20

A critical step in the infection process is the adhesion of pathogenic bacteria to the bladder mucosa. The high prevalence of gram-negative pathogens such as E coli and Klebsiella may be due to the pathogens ability to adhere to the urinary tract mucosa.21 This increased adherence in the presence of glycosuria and decreased functionality of neutrophils in diabetic patients results in an increased incidence of UTI. The low urinary pH caused by bacterial metabolism does not inhibit bacterial growth in this population.

Asymptomatic bacteriuria in the diabetic patient requires special assessment. Women with type 2 diabetes and asymptomatic bacteriuria have been found to have an increased risk of developing a UTI during 18-month follow-up .22

What Is The Outlook

Most people improve within a few days of starting treatment. See a doctor if you do not quickly improve. If your symptoms do not improve despite taking an antibiotic medicine then you may need an alternative antibiotic. This is because some bacteria are resistant to some types of antibiotics. This can be identified from tests done on your urine sample.

Are Any Tests Needed

In some cases the diagnosis may be obvious and no tests are needed. A test on a urine sample can confirm the diagnosis and identify what germ is causing the infection. Sometimes a dipstick test can provide enough information immediately. In other cases the urine sample is sent to a laboratory for further examination under a microscope. This result takes several days.

Further tests are not usually necessary if you are otherwise well and have a one-off infection. However, your doctor may advise tests of your kidney or bladder if an underlying problem is suspected. If you are a man, you may be advised to have some tests for your prostate gland.

An underlying problem is more likely if the infection does not clear with antibiotic medication, or if you have:

  • Symptoms that suggest a kidney is infected .
  • Recurring urine infections .
  • Had problems with your kidney in the past, such as kidney stones or a damaged kidney.
  • Symptoms that suggest a blockage to the flow of urine.
