UTI Protocol: ABCs 6

Asymptomatic Bacteriuria (ASB) Laboratory diagnosis Positive urine culture – Colony count significant (> 10⁵ cfu/mL) Absence of symptoms Clinical Infectious Disease 2010;50:

Prevalence of ASB POPULATION Prevalence % Older long-term care residents – Women25-50 – Men15-40 Patients with an indwelling catheter – Short-term9-23 – Long-term100 CID2005;40:

Change in Mental Status ≠ Symptomatic Urinary Tract Infection LTCF residents with cognitive impairment are more likely to have ASB (no symptoms, positive urine culture). LTCF residents with cognitive impairment are more vulnerable to changes in mental status with any new problem. THEREFORE, resident with cognitive impairment and change in mental status MORE LIKELY to have a positive urine culture, Independent of whether infection is the cause of clinical decline, OR if infection is present, whether urinary tract is the source. JAGS :

Change in Mental Status in Dementia Acute change in cognition – Confusion Acute change in behavior – Aggression or agitation (verbal or physical) – Resistance to care – Hallucinations – Delusions – Lethargy Acute change in function (activities of daily living) 10

Acute Change in Mental Status: Confusion DELIRIUM: Acute change in mental status from baseline with acute onset 1.Fluctuating course 2.Inattention AND 3.Disorganized thinking OR 4.Altered level of consciousness. McGeer Revised

Confusion Assessment Method Criteria Acute change in resident’s mental status from baseline Fluctuating Behavior – Coming and going or changing in severity during the assessment. Inattention – Difficulty focusing attention (e.g., unable to keep track of discussion or easily distracted). Disorganized thinking – Thinking is incoherent (e.g., rambling conversation, unclear flow of ideas, unpredictable switches in subject). Altered level of consciousness – Level of consciousness is described as different from baseline (e.g., hyperalert, sleepy, drowsy, difficult to arouse, nonresponsive). McGeer Revised

Course of Subsyndromal Delirium Long Term Care Residents There may be a continuum between no delirium and full delirium characterized by – Increasing number of symptoms – Increasing duration of episodes Am J Geri Psych March

Acute Change in Mental Status: Behavioral Problems Agitation Anxiety Resistance to care Disinhibited behaviors Depression Hallucinations Delusions 14

Acute Change in Mental Status: Behavioral Problems Alzheimer's disease – Apathy, agitation, anxiety, – Depression, irritability Dementia with Lewy bodies – Visual hallucinations, delusions, depression, REM sleep behavior disorder Vascular dementia – Apathy, depression, delusions Dementia associated with Parkinson's disease – Visual hallucinations, delusions, depression, REM sleep behavior disorder Frontotemporal dementia – Apathy, disinhibition, elation, repetitive behaviors, appetite or eating changes Progressive supranuclear palsy – Apathy, disinhibition Corticobasal degeneration – Depression Lancet Neurology November

The influence of regional pathologies on neuropsychiatric symptom formation Top: apathy and behavioural disinhibition in Alzheimer's disease are associated with reduced frontal lobe activity. Bottom: visual hallucinations and misidentification syndromes in DLB are by contrast, probably generated by reductions in posterior visual cortical activity. Ian McKeith, Jeffrey Cummings Behavioural changes and psychological symptoms in dementia disorders The Lancet Neurology Volume 4, Issue

When Antibiotics are Not Prescribed (Monitoring Protocol) Monitor vital signs for several days Monitor for progression of symptoms or change in clinical status Encourage fluid intake Consider alternate diagnosis for nonspecific symptoms If symptoms resolve, no further intervention required Annals of LTC April 2012;20:

Sample Checklist 30

Consider Urgent Evaluation Significantly abnormal vital signs – Systolic BP 120, respirations >30, temperature 101 Signs of distress – New onset respiratory distress with increasing hypoxia or dyspnea Signs of serious underlying condition – For example, symptoms of stroke Escalating aggressive or violent behavior Resident is a threat to self or others AMDA Clinical Practice Guidelines Delirium LTC Setting
