Management of New Onset Fever in Long-Term Care Facility Residents

Immediate Initial Assessment

Nursing staff should immediately obtain vital signs, including temperature, pulse, blood pressure, and respiratory rate, within 30 minutes of recognizing fever, followed by prompt clinical assessment and laboratory evaluation within 12-24 hours, according to the Infectious Diseases Society of America 1
Obtain complete vital signs immediately, with particular attention to respiratory rate, as rates >25 breaths/min have 90% sensitivity and 95% specificity for pneumonia diagnosis, as recommended by the American Geriatrics Society 2
Assess blood pressure and pulse to identify hemodynamic instability, as suggested by the Infectious Diseases Society of America 1

The clinical evaluation must specifically assess respiratory rate and chest examination, as pneumonia is the most common serious infection, according to the American Geriatrics Society 6
Assess hydration status and mental status changes, as altered mental status, new confusion, decreased mobility, and decreased appetite suggest infection in the elderly, as recommended by the American Geriatrics Society 6
Examine the oropharynx and conjunctiva, as well as the skin, including sacral, perineal, and perirectal areas, to identify potential infection sources, as suggested by the American Geriatrics Society 6
Evaluate indwelling devices, such as urinary catheters, which confer a 39-fold increased risk of bacteremia, according to the American Geriatrics Society 6

Obtain a complete blood count with manual differential to evaluate band forms, as an elevated band count >1,500/mm³ has the highest likelihood ratio for bacterial infection, as recommended by the Infectious Diseases Society of America 8
Perform site-specific cultures based on the suspected source of infection, such as blood cultures for fever without a clear source, urine culture for UTI symptoms, and respiratory cultures if obtainable for pneumonia, as suggested by the Infectious Diseases Society of America 8
Order a chest radiograph when pneumonia is suspected or in cases of fever without a clear source, as recommended by the Infectious Diseases Society of America 9

Advance directives significantly impact the extent of evaluation, and "comfort care only" residents receive less evaluation and treatment, but this reflects appropriate goal-concordant care rather than inadequate management, according to the American Geriatrics Society 6
Historical data shows that only 21% of long-term care facility infections were "adequately" evaluated by acute-care standards, but these standards may not be appropriate for long-term care facility settings, as suggested by the Infectious Diseases Society of America 9

Empiric antibiotics should be started promptly once infection is clinically diagnosed and cultures are obtained, as recommended by the Infectious Diseases Society of America 3
Avoid administering antibiotics without a clinical examination, as 17% of residents received antibiotics without any clinical examination, according to the American Geriatrics Society 6

If multiple residents develop fever, immediately confirm the diagnosis in the index patient, derive a uniform case definition, perform chart review and prospective surveillance, plot the epidemic curve, notify the medical director, infection control practitioner, and public health authorities, and implement isolation procedures as indicated, as recommended by the Infectious Diseases Society of America 1

Two key quality metrics for skilled nursing facility fever management are vital signs obtained within 30 minutes of suspected infection and a complete blood count with differential performed within 12-24 hours for residents without prohibitive advance directives, as recommended by the Infectious Diseases Society of America 1
