characterized by a pruritic, maculopapular vesicular rash that evolves into noninfec- tious dried crusts over a 5- to 6-day period. It is triggered by a decline in cell­mediated immunity that facilitates the reactivation of latent varicella virus. Long-term care residents are at greater risk because of age-related decline in cell­medicated immunity, malnutrition, multimorbidity, and frailty. They also have diminished reserves to respond to stress that can trigger an episode of HZ.
Prodromal symptoms can include hyperesthesia, localized pain, or itching. The
lesions of HZ are often described as a “dew drops on a rose petal,” which are clus­tered in a dermatomal distribution and not crossing the midline. Most often, HZ is diagnosed clinically, but the laboratory diagnosis can be made by isolation of the varicella virus from a lesion. Rapid varicella virus identication using PCR is pre­ferred if available, but direct uorescent antibody (DFA) testing can be used to make the diagnosis as well.
About 20% of affected older persons may develop post-herpetic neuralgia
(PHN). This can be a devastating complication requiring prolonged pharmacother­apy and pain management and lead to depression and a decline in function. Other complications may include involvement of the ophthalmic branch of the trigeminal branch (leading to uveitis, keratitis, blindness), the nasociliary branch (vesicles in the pharynx and tip of the nose), and the Ramsay Hunt syndrome (vesicles in the ear, deafness, facial palsy, vertigo).
N. Pandya
General Measures
The nursing leadership and medical staff should educate the resident and direct staff caregivers regarding the nature of the infection and the risk of viral transmission to individuals who have not had chickenpox. HZ is not contagious to those who have a history of chicken pox or adequate titers of IgG to varicella. Skin lesions should be kept clean and dry to avoid bacterial superinfection. Antibiotic ointments and adhesive dressings should be avoided since healing and drying of the lesions will be delayed. Shingles in immunocompromised individuals and those with ophthalmic zoster must be treated with antiviral agents
Vaccination
Encourage Zoster vaccination for persons 50years and older, regardless of prior history of a natural HZ infection unless a contraindication exists. It is not recom­mended for immunocompromised individuals [42]. Although zoster vaccine (Zostavax) in general has been associated with 51% fewer episodes of HZ, and 66% less PHN, these gures were only 18% and 26%, respectively, in those 80 and over. Hence response to the vaccine in LTC residents cannot reliably be predicted and facility immunization programs for herpes zoster are not currently recommended.

The Shingrix vaccine released in 2019 is 97% effective in preventing HZ in those >50years, and should be given in two doses, 2–6months apart [42, 43].
Treatment
• Topical antiviral treatment is not efcacious.
• Systemic antiviral treatment is recommended if ≥50year age, moderate to severe pain or rash; or have non-truncal involvement within 72h of rash onset. Begin immediately or sooner than 72h, if neurologic or ocular signs, severe pain, and/ or rash. Monitor renal function in those with renal insufciency.
– Acyclovir 800mg, ve times daily (every 4–5h) for 7–10days (less preferred
due to dosing schedule) – Famciclovir 500mg, three times daily for 7days – Valacyclovir 1000mg, three times daily 7days
• Adjuncts to antiviral therapy consider:
– Analgesics (acetaminophen, opioids, tramadol) – Gabapentin (maximum 3600mg daily), pregabalin (75mg twice daily), or a
low dose tricyclic antidepressant (nortriptyline 25mg at bedtime, occasion-
ally up to 150mg daily), if no improvement in pain
• Oral corticosteroid use is common but lacks evidence in improving quality of life or reducing the incidence of PHN.
• Referral to a pain specialist is recommended to evaluate for neural blockade if analgesics, adjunct therapies, and corticosteroids have not been effective in relieving post-herpetic neuralgia.
• Psychosocial evaluation if severe depression
• Attention to both nutrition and maintenance of functional status
Clostridioides difcile Infection
Clostridioides difcile (C. difcile) infections (CDI) are a serious cause of morbid­ity and mortality in the post-acute and long-term care setting. Nationwide 500,000 infections occur annually. One in six patients with CDI experience a recurrence in the subsequent 2–8weeks, and one in eleven adults over 65years diagnosed with a healthcare-associated CDI, die within 1 month [CDC website] [43, 44]. C. difcile colonizes the gut after the normal gut ora has been altered by antibiotic treatment. More virulent strains are emerging and the NAP1/BI/027 strain has been implicated in CDI outbreaks, and is capable of increased production of toxins A and B.About 8–10% of PA/LTC residents are thought to be carriers. The infection is transmitted in health care facilities from environmental surface contamination, hand carriage by staff members, and infected patients (Table34).
156
Table 34 Risk factors for C. difcile
• Advanced age
• Frequent need for hospitalization
• Recurrent exposure to antibiotics (especially clindamycin, third-generation cephalosporins, and uoroquinolones)
• Presence of comorbid medical conditions
• Use of proton-pump inhibitors or histamine 2 receptor antagonists for gastric acid suppression
• Immunosuppression (organ transplant with immunosuppressive therapy, HIV/AIDS, cancer)
N. Pandya
Clinical Features
Older adults may be asymptomatic, or symptomatic with watery diarrhea, abdomi­nal cramps, constipation or ileus, and fever, though patients may be afebrile.
Symptoms may begin during antibiotic treatment or up to 8weeks after completion of antibiotics. In PA/LTC residents, diarrhea may not be the initial problem, but
fever, confusion, abdominal pain, anorexia, nausea, leukocytosis (often >20,000 WBC), and hypoalbuminemia. A distinctive fecal odor is also a manifestation of CDI.The differential diagnosis of CDI includes an acute abdomen (due to ileus, volvulus, ischemia), shock (due to sepsis or cardiogenic), infectious diarrhea (due to antibiotics or salmonella or clostridium perfringens), or noninfectious causes (e.g., celiac disease, Crohn’s, ulcerative colitis, collagenous colitis, IBS, fecal impaction).
Diagnosis should be made by testing diarrheal stool. Options are:
• C. diff toxin testing by enzyme immunoassay (EIA) for toxins A and B
• PCR testing for toxins A and B is superior and can be available in 1h. Beware of false positives.
• EIA testing for C. difcile glutamate dehydrogenase (GDH), but it cannot distin­guish between toxigenic and nontoxigenic strains; results available in 1h and may be used as a screening test.
• Repeat testing to conrm cure is not recommended!
• Discontinue the use of any potentially inciting antibiotics and avoid the use of antiperistaltic agents!
• Consider discontinuing proton pump inhibitors (PPIs).
Management
• For mild to moderate disease (diarrhea plus other symptoms not meeting severe or complicated criteria);
• Metronidazole 500mg p.o. TID for 10–14days
• Discontinue unnecessary antibiotics

• Vancomycin 125mg p.o. QID if unable to take metronidazole or no improve-
ment in 5–7days
• For severe disease (albumin <3g/dL and one of the following: WBC >15,000, or abdominal tenderness);
– Vancomycin 125mg p.o. QID
• For severe and complicated disease (ICU admission, hypotension, fever, ileus or abdominal distension, confusion, WBC >35,000 or <2000), lactate >2mmol/L)
– Vancomycin 500mg p.o. QID – Vancomycin by enema (500mg in 500mL normal saline QID and metroni-
dazole 500mg IV q 8 h if oral therapy is not tolerated
• For recurrent C. diff infection (10–20% recur within 8weeks)
– Conrm diagnosis – Conservative treatment for mild symptoms – Same regimen as for the initial episode – “Pulsed vancomycin” regimen – Fidaxomycin 200mg BID for 10days (questionable efcacy) (expensive) – Fecal microbiota transplantation may be safe and effective in restoring nor-
mal ora
The use of private rooms will reduce transmission. Antibiotic stewardship is cru-
cial as is hand hygiene and the maintenance of contact precautions using gowns and gloves when entering the room of a patient with CDI.Environmental surfaces should be disinfected using an approved sporicidal agent. Proton pump inhibitors should be used judiciously or discontinued. Moreover, there is no conclusive evidence sup­porting the use of probiotics though commonly prescribed during C. difcile treat­ment or as preventive therapy when antibiotics are prescribed for other infections.
Acute Kidney Injury
Renal function declines in many older adults, and thus are vulnerable to acute kid­ney injury due to age-related changes in renal functions that include:
• Decrease in glomerular ltration rate (GFR)
• Decrease in urine concentrating ability (leading to nocturia, hypernatremia, poor compensation for hypovolemia)
• Reduced sodium conservation in the face of low sodium intake (risk of volume depletion)
• Reduced sodium excretion in the face of high sodium intake (risk of edema and salt-sensitive HTN)
• Decreased potassium excretion (risk of hyperkalemia)
158
N. Pandya
Acute kidney injury (AKI), is dened as an acute increase in creatinine or a
decrease in urine output to <0.5mL/kg/h for at least 6h. It is increasingly com­mon in older adults and can result in increased morbidity and even the need for dialysis. Its incidence increases with older age, male gender, black race, chronic inammation, and those with poor nutritional status [44, 45]. The causes of AKI and its evaluation are reviewed in Table35 [45]. Due to low muscle mass related to aging and frailty, serum creatinine may be normal or near normal despite severe impairment of renal function. In evaluating for the cause of AKI, it is useful to classify it as prerenal, intrinsic renal (glomerular, tubulointerstitial, and vascular), and postrenal causes.
Table 35 Causes of AKI and evaluation
Category of AKI Causes Clinical ndings Treatment
Prerenal azotemia
Obstructive uropathy
• Hypoperfusion due to volume depletion (reduced uid intake, acute illness, GI uid loss, diuresis)
• Low arterial volume (decompensated HF)
• Renal hypoperfusion (e.g., bilateral renal artery stenosis)
• Medications (e.g., ACEI, ARBs, NSAIDS, diuretics, SGLT2i)
• Bladder outlet obstruction (e.g., BPH in men)
• Bladder carcinoma
• Urethral stricture
• Functional outlet obstruction (e.g., anticholinergic medications, spinal cord injury, diabetic autonomic neuropathy)
• Ureteral obstruction (stones, strictures, or retroperitoneal malignancy)
• History
• Orthostatic hypotension
• Urinalysis: high specic gravity, bland urine sediment
• Urinary hesitancy, nocturia, overow incontinence
• GFR maintained if only one kidney affected (unless unilateral kidney present)
• Renal ultrasound shows hydronephrosis, stones
• Stop or reduce offending medications
• Restore intravascular circulating volume with oral hydration or intravenous uids
• Bladder emptying (may need to be scheduled or indwelling bladder catheter)
• Specic treatment depending on the cause and level of obstruction

Conclusion
The management of medical conditions in patients and residents in the long-term care continuum is challenging due to patient complexity, multimorbidities, guarded prognosis, individual advance directives for health care, goals of care, and the health care setting in which care is being provided by an interprofessional team, under the scrutiny of government and survey agencies. It is essential for practitioners to deter­mine the risks and benets to patients in the identication, assessment, treatment, and monitoring in the management of multiple clinical conditions. Practitioners need not forget less common conditions that can afict residents such as cancer, Parkinson’s disease, polymyalgia rheumatica, traumatic brain injury, and abuse and neglect.
Peals for the Practitioner
• Studies have shown that the treatment of HTN in those over age 80 can result in a signicant reduction in fatal and nonfatal stroke and all-cause mortality within 1–2years of starting antihypertensive treatment.
• A systematic evaluation is recommended for residents with anemia, and should be evaluated for comorbid conditions such as loss of physical function, risk for falls, and cognitive impairment.

N. Pandya
• Residents with HF have a 74% or 92% 5-year mortality with either a normal or reduced LVEF, respectively. HF is a major cause of hospital admissions and readmissions.
• COPD, the third leading cause of US deaths, is present in one in six people admitted to nursing facilities and yet remains either unrecognized or subopti­mally treated.
• Effective management of diabetes requires an approach that is multifaceted, protocol- driven, interdisciplinary, and individualized. If used, sliding-scale insu­lin is best utilized as a supplement to scheduled oral hypoglycemic agents and/or basal insulin therapy and not as a primary means to control blood glucose.
• Subclinical hypothyroidism is both common and not associated with the classic signs and symptoms of hypothyroidism are often seen in younger adults. It is not uncommon in those already diagnosed with DM or vitamin B12 deciency.
• Vitamin B12 deciency in older adults is commonly not associated with anemia or macrocytosis, so a high index of suspicion is warranted as to its possible presence.
• For scabies, permethrin 5% cream has a 90% effective cure rate after its rst application. A second application may be necessary 7–10days.
• Shingrix vaccine is 97% effective in preventing HZ in those 50years and older. It is given in two doses, 2–6months apart.
