Long-Term Care Hospitals Face Little Scrutiny

“We see such sick people.” Dr. David Jarvis, national medical director for the Select Medical Corporation

By ALEX BERENSONPublished: February 9, 2010

Long Term Acute Care Hospitals (LTACHs)

• Official definition:– Patients are required to have medically complex

situations and a mean length of stay of ≥ 25 days

• Simple definition:– An island of intensive care

Long -Term Acute Care Hospitals: LTACHs

• The Perfect Storm:– Device utilization high– Rate of colonization at admission high– Rate of antibiotic use high– Duration of hospitalization prolonged

Gould etal. ICHE 2006; 27:920-925

Recipe for Disaster

• New antibiotics or old antibiotics resurrected- difficulties with antibiotic stewardship

• Specialty facilities for long term care, LTACHs and dialysis units

• More demands on ICPs• Outsourcing microbiology• Devices and respiratory care

Long Term Care Facilities (LTCFs)

• Some LTCFs have medically complex patients who are ventilated with prolonged lengths of stay

• They may have combinations of patients:– Ventilated patients with central lines– Older adults with less nursing care requirements– Alzheimers unit– Psychiatric unit

• They are not “LTACHs”--- using medicare definitions……..

Burning Issues• Bloodborne pathogens

• Multidrug-resistant organisms (MDROs)

Multidrug-resistant Organisms (MDROs)

MDROs and Long Term Care

• Including:– KPC (Klebsiella pneumoniae carbapenemase)

containing organisms– Elizabethkingia meningoseptica– Clostridium difficile

– Acinetobacter spp, Pseudomonas aeruginosa, Staphylococcus aureus, etc……….

Some Background on Enterobacteriaceae

• Bacteria in Enterobacteriaceae group are common causes of community and healthcare acquired infections.

• E. coli is the most common cause of outpatient urinary tract infections.

• E. coli and Klebsiella species (especially K. pneumoniae) are important causes of healthcare associated infections.– Together they accounted for 15% of all HAIs

reported to NHSN in 2007. CDC, 2009

Klebsiella Pneumoniae Carbapenemase

• KPC is a class A -lactamase– Confers resistance to all -lactams including extended-spectrum

cephalosporins and carbapenems

• Occurs in Enterobacteriaceae– Most commonly in Klebsiella pneumoniae– Also reported in: K. oxytoca, Citrobacter freundii, Enterobacter

spp., Escherichia coli, Salmonella spp., Serratia spp.,

• Also reported in Pseudomonas aeruginosa (South America)

KPC Enzymes

• Located on plasmids; conjugative and nonconjugative

• blaKPC is usually flanked by transposon sequences

• KPC-2 and KPC-3 most common in the US

• blaKPC reported on plasmids with:– Normal spectrum -lactamases– Extended spectrum -lactamases– Aminoglycoside resistance– Fluoroquinolone resistance

Risk Factors for and Outcomes of CRKP Infections

• Case control studies done by Patel et al. at Mount Sinai in NYC, where CRKP are now endemic. – 99 patients with invasive CRKP infections

compared to 99 patients with invasive carbapenem susceptible K. pneumoniae infections.

Recent Outbreaks of KPC Producing Klebsiella

• September 2008: Acute care hospital in Ponce, Puerto Rico.

• November 2008: Long term care facility in IL.• Methodology:

– Review of microbiology data for case finding– Review of infection control practices– Surveillance cultures of patients who were

epidemiologically associated with cases.

CDC, 2009

Infection Control Observations-Puerto Rico and IL

• Staff entering rooms without donning a gown, occasionally no gloves or hand hygiene

• Reuse of gloves between rooms with no hand hygiene.

• Exiting rooms without removing gowns• Touching patients and equipment without PPE• Inconsistent PPE use during wound care, respiratory

care

CDC, 2009

CRKP Outbreaks-Lessons Learned

• Healthcare epidemiology/infection control staff at some facilities might not be aware that CRKP are actually present.

• The etiology of outbreaks of CRKP are multi-factorial, but are due in part to:– Non-compliance with infection control– Unrecognized carriers serving as reservoirs

for transmission

CDC, 2009

E. meningoseptica

• Also known as:– Flavobacterium meningosepticum– Chryseobacterium meningosepticum

• Found in soil and water• Identified in neonatal wards• Immunocompromised adults

Long Term Acute Care Hospital (LTACH) Facility A

• Converted to LTACH in 2006• Individual patient rooms• Ventilators and wound care• Average daily census = 55 patients • Average patient stay = 30 days

Responses

• Consider targeted active surveillance cultures if clusters or increased cases identified

• Inservices or education• Improve environmental disinfection• No tap water to come into direct contact of patient

devices • Standardize respirator cleaning• Admission screening of trach patients• Specific communications regarding resistant

organism information for patient transfers

Clostridium difficile and Long Term Care

• Recent one month surveillance of C. difficile in Cook County, September, 2009

• Patients with the BI strain were frequently transferred between acute care hospitals and long term care facilities in Cook County

Conclusions

• Increase infection control activities in long term care

• Improved communication between acute and long term care

• Can public health help bridge the gap between acute and long term care?
