Understanding Urinary Tract Infections (UTIs) in Older Adults: A Guide for Domiciliary Care Staff

Writer's picture: Kirsten ProtheroughKirsten Protherough

Updated: 2 days ago

Urinary tract infections (UTIs) are a prevalent health issue among older adults, particularly those receiving domiciliary (home-based) care. Recognizing the signs and symptoms early, along with effective management strategies, is critical to avoid complications. This blog post will discuss the importance of early assessment and management of UTIs in individuals over 65. It will focus on how domiciliary care staff can play a vital role in promoting good urinary health.


1. Why Are Older Adults More Susceptible to UTIs?


Weakened Immune System

As people age, their immune systems may not respond as effectively to infections. This decline in immunity increases the risk of bacterial overgrowth, making older adults more susceptible to UTIs.


Underlying Medical Conditions

Chronic conditions like diabetes, kidney disease, and urinary incontinence heighten the risk for UTIs. Reduced mobility can also compound vulnerability, affecting circulation and personal hygiene practices.


Bladder and Pelvic Floor Changes

Aging can lead to changes in bladder function and pelvic floor muscle strength. These changes may result in incomplete bladder emptying, which allows bacteria to multiply.


Dehydration

Reduced thirst sensation in older adults can lead to inadequate fluid intake. This results in concentrated urine, providing an environment conducive to bacterial growth.


2. Recognizing the Signs and Symptoms


In older adults, typical UTI symptoms, such as a burning sensation during urination or frequent urges, may be absent or subtle. Instead, UTIs often present with atypical or non-specific symptoms, including:


  • Increased Confusion or Delirium

Sudden mental status changes, such as confusion or agitation, could signal an infection.


  • Loss of Appetite

Nausea or diminished appetite may indicate an underlying issue.


  • New or Worsening Incontinence

Changes in urinary patterns might point to a urinary infection.


  • Fatigue and Lethargy

General tiredness or unusual sleepiness can be linked to infections.


  • Abdominal or Lower Back Pain

Non-specific pain in these areas may suggest bladder or kidney involvement.


Key Point for Domiciliary Care Staff

Since older adults often show subtle or atypical symptoms, being aware of behavioral or functional changes is just as vital as monitoring for classic UTI symptoms.


3. Initial Assessment in Domiciliary Care


Domiciliary care staff often notice changes in an older person’s condition first. Here are some actionable steps:


  1. Monitor Vital Signs

    Check for fever (which may not always be present), changes in blood pressure, or increased heart rate.


  2. Observe Urine Characteristics

    Pay attention to any changes in urine color, cloudiness, foul odor, or blood presence.


  3. Track Fluid Intake

    Maintain a daily log of fluid intake as dehydration can exacerbate UTI risk.


  4. Record Changes in Behavior

    Document any signs of confusion, disorientation, agitation, or increased lethargy.


  5. Document Pain and Discomfort

    Keep a record of any complaints of lower abdominal or back pain, including frequency and intensity.


  6. Conduct Urine Tests

    If a UTI is suspected, antibiotics may need to be initiated without waiting for lab results. Further, urine samples should be sent to the lab for culture.


4. When to Seek Medical Advice


If a domiciliary care staff member suspects a UTI, it is crucial to escalate concerns promptly. Key indicators that medical advice is necessary include:


  • Persistent or worsening confusion.

  • Signs of dehydration (dry mouth, decreased urination, feeling faint).

  • High fever or chills (if present).

  • Increasing pain or discomfort.

  • Presence of blood in the urine.


Early intervention is essential to prevent complications, such as kidney infections (pyelonephritis) or sepsis.


5. Management Strategies


A. Non-Pharmacological Approaches


Hydration

Encourage adequate fluid intake to help flush out bacteria. Offer water, herbal teas, and diluted fruit juices while considering any fluid restrictions advised by healthcare professionals.


Hygiene and Continence Care

  • Assist with toileting and personal hygiene regularly.

  • Ensure proper wiping techniques (front to back for women).

  • Use gentle, pH-balanced cleansing products in intimate areas.

  • Change incontinence pads promptly to prevent bacterial growth.


Nutritional Support

Provide a balanced diet rich in nutrients to bolster overall health and immunity. Foods high in vitamin C, like berries and citrus fruits, may assist in acidifying urine.


Bladder Training

Encourage scheduled toileting if manageable. Incorporate pelvic floor exercises under healthcare professional guidance.


Monitoring

Continue tracking vital signs, fluid intake, urine characteristics, and overall well-being.


B. Pharmacological Management


Antibiotic Therapy

If a UTI is confirmed, healthcare professionals may prescribe antibiotics based on culture results, local guidelines, and the patient’s clinical condition.


Analgesics

Over-the-counter pain relief, such as paracetamol, can alleviate discomfort if approved by a healthcare provider.


Medication Reviews

Regularly review medications with healthcare professionals, as some medications may elevate UTI risk or interact with antibiotics.


6. Preventing Future UTIs


  1. Routine Health Checks

    Encourage regular check-ups and urine tests, especially with recurrent UTIs or underlying risk factors.


  2. Lifestyle Modifications

    Promote mobility and gentle exercise, maintain good personal hygiene, and encourage adequate fluid intake.


  3. Probiotics

    Some healthcare providers may recommend probiotics or foods with live cultures to promote a healthy urinary tract environment.


  4. Cranberry Products

    The effectiveness of cranberry products in preventing UTIs is debated. Some individuals find success with cranberry juice or capsules. It’s advisable to consult a healthcare provider before trying these, particularly regarding medication interactions (e.g., warfarin).


7. Role of Domiciliary Care Staff


Domiciliary care staff are vital allies in promoting the health and well-being of older adults:


  • Early Detection

Observe and document physical and mental status changes to facilitate early medical intervention.


  • Coordination of Care

Collaborate with GPs, district nurses, and pharmacists for timely assessments, diagnostics, and treatments.


  • Education and Support

Empower individuals by explaining the significance of hydration, hygiene, and nutrition in urinary tract health.


Communication is Key

Promptly share any concerns or observations with family members and other healthcare providers to enable a swift and coordinated response.


Conclusion

UTIs in older adults can present differently and lead to serious complications if not detected and treated early. By remaining vigilant, maintaining good hygiene, ensuring adequate hydration, and collaborating closely with healthcare professionals, domiciliary care staff can significantly reduce the impact of UTIs on the health and well-being of older adults.


A Case Scenario


Mrs. Roberts, an 82-year-old living alone with domiciliary care support

  • Recently, her caregiver, Angela, has observed that Mrs. Roberts appears more confused and agitated—unusual for her typically calm and cheerful demeanor.

  • She has been refusing her usual afternoon snacks, leading to low fluid intake.

  • Additionally, Mrs. Roberts complains of mild lower back pain.

  • Angela checks the urine container and notices the urine appears darker and has a slight odor.


Initial Concerns

Angela suspects a possible UTI due to Mrs. Roberts' changes in mental state, appetite, and urine characteristics.


Action Steps

  1. Angela documents her observations about Mrs. Roberts.

  2. She informs the nursing supervisor, who advises an urgent GP review.

  3. A urine sample is collected (if feasible) and sent for testing.

  4. The GP prescribes antibiotics based on preliminary findings while awaiting lab results.


This scenario demonstrates how behavioral cues, urine changes, and general well-being can prompt the early detection and treatment of a UTI.
