Home Hospital for Suddenly Ill Adults
Home Hospital for Suddenly Ill Adults
The investigators propose a home hospital model of care that substitutes for treatment in an
 acute care hospital. Limited studies of the home hospital model have demonstrated that a
 sizeable proportion of acute care can be delivered in the home with equal quality and safety,
 reduced cost, and improved patient experience.
Hospitals are the standard of care for acute illness in the United States, but hospital care
 is expensive and often unsafe, especially for older individuals. While admitted, 20% suffer
 delirium, over 5% contract hospital-acquired infections, and most lose functional status that
 is never regained. Timely access to inpatient care is poor: many hospital wards are typically
 over 100% capacity, and emergency department waits can be protracted. Moreover, hospital care
 is increasingly costly: many internal medicine admissions have a negative margin (i.e.,
 expenditures exceed hospital revenues) and incur patient debt.

 The investigators propose a home hospital model of care that substitutes for treatment in an
 acute care hospital. Studies of the home hospital model have demonstrated that a sizeable
 proportion of acute care can be delivered in the home with equal quality and safety, 20%
 reduced cost, and 20% improved patient experience. While this is the standard of care in
 several developed countries, only 2 non-randomized demonstration projects have been conducted
 in the United States, each with highly local needs. Taken together, home hospital evidence is
 promising but falls short due to non-robust experimental design, failure to implement modern
 medical technology, and poor enlistment of community support.

 The home hospital module offers most of the same medical components that are standard of care
 in an acute care hospital. The typical staff (medical doctor [MD], registered nurse [RN],
 case manager), diagnostics (blood tests, vital signs, telemetry, x-ray, and ultrasound),
 intravenous therapy, and oxygen/nebulizer therapy will all be available for home hospital.
 Optional deployment of food services, home health aide, physical therapist, occupational
 therapist, and social worker will be tailored to patient need. Home hospital improves upon
 the components of a typical ward's standard of care in several ways:

 Point of care blood diagnostics (results at the bedside in <5 minutes); Minimally invasive
 continuous vital signs, telemetry, activity tracking, and sleep tracking; On-demand 24/7
 clinician video visits; 4 to 1 patient to MD ratio, compared to typical 16 to 1;
 Ambulatory/portable infusion pumps that can be worn on the hip; Optional access to a personal
 home health aide Should a matter be emergent (that is, requiring in-person assistance in less
 than 20 minutes), then 9-1-1 will be called and the patient will be returned to the hospital
 immediately. In previous iterations of home hospital this happens in about 2% of patients.

 Clinical parameters measured will be at the discretion of the physician and nurse, who treat
 the participant following evidence-based practice guidelines, just as in the usual care
 setting. In addition, the investigators will be tracking a wide variety of measures of
 quality and safety, including some measures tailored to each primary diagnosis.
Inclusion Criteria:

 -  Resides within either a 5-mile or 20 minute driving radius of emergency department

 -  Has capacity to consent to study OR can assent to study and has proxy who can consent

 -  >= 18 years-old

 -  Can identify a potential caregiver who agrees to stay with patient for first 24 hours
 of admission. Caregiver must be competent to call care team if a problem is evident to
 her/him. After 24 hours, this caregiver should be available for as-needed spot checks
 on the patient. This criterion may be waived for highly competent patients at the
 patient and clinician's discretion.

 -  Primary or possible diagnosis of cellulitis, heart failure, complicated urinary tract
 infection, pneumonia, COPD/asthma, other infection, chronic kidney disease, malignant
 pain, diabetes and its complications, gout flare, hypertensive urgency, previously
 diagnosed atrial fibrillation with rapid ventricular response, anticoagulation needs,
 or a patient who desires only medical management that requires inpatient admission, as
 determined by the emergency room team.

 facility)

 -  Domestic violence screen positive

 -  Acute delirium, as determined by the Confusion Assessment Method

 -  Cannot establish peripheral access in emergency department (or access requires
 ultrasound guidance)

 -  Secondary condition: end-stage renal disease, acute myocardial infarction, acute
 cerebral vascular accident, acute hemorrhage

 -  Primary diagnosis requires multiple or routine administrations of intravenous
 narcotics for pain control

 -  Cannot independently ambulate to bedside commode

 procedures: computed tomography, magnetic resonance imaging, endoscopic procedure,
 blood transfusion, cardiac stress test, or surgery
