Rural Home Hospital: Proof of Concept

Patient clinical inclusion Criteria:

• >=18 years old
• Any infectious process (e.g., pneumonia, diverticulitis, cellulitis, complicated urinary tract infection)
• Heart failure exacerbation
• Asthma and chronic obstructive pulmonary disease exacerbation
• Atrial fibrillation with rapid ventricular response
• Diabetes and its complications
• Venous thromboembolism: This includes a patient who requires therapeutic anticoagulation and concomitant monitoring (thus requiring inpatient status)
• Gout exacerbation
• Chronic kidney disease with volume overload
• Hypertensive urgency
• End of life / desires only medical management: Regarding a patient who desires only medical management, this includes a patient who requires acute care for symptom management but declines any surgical intervention. This may include a patient who is about to transition to hospice care, for example, but still has the functional capacity to meet our criteria below. Under these circumstances, we would make sure that various contingencies, including possible transition to hospice care or hospital readmission, are completely understood by patients and caregivers as applicable.

Patient social inclusion criteria:

• Lives in rural or ultra-rural area (see definitions in Appendix) that can be served by one of our RHH clinicians.
• Has capacity to consent to study
• 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 maybe waived for highly competent patients at the patient and clinician's discretion.

Patient caregiver inclusion criteria: (not required for patient participation):

• Age >= 18 years old
• Has capacity to consent to study
• Lives with or nearby to patient

Clinician inclusion criteria:

-Any member of the rural home hospital (RHH) clinical team (MD, RN, paramedic, NP) who will be participating in the screening and recruitment of patients for the rural home hospital intervention and/or providing care to rural patients that enroll in the intervention.

Patient Clinical Exclusion Criteria:

• Acute delirium, as determined by the Confusion Assessment Method
• Cannot establish peripheral access (or access requires ultrasound guidance, unless ultrasound guidance is available)
• Secondary condition: active non-melanoma/prostate cancer, end-stage renal disease, acute myocardial infarction, acute cerebral vascular accident, acute hemorrhage
• Primary diagnosis requires controlled substances
• Cannot independently ambulate to bedside commode
• As deemed by on-call MD, patient likely to require any of the following procedures that have not already occurred: computed tomography, magnetic resonance imaging, endoscopic procedure, blood transfusion, cardiac stress test, or surgery
• For pneumonia: Most recent CURB65 > 3: new confusion, BUN > 19mg/dL, respiratory rate>=30/min, systolic blood pressure =65 ( 2: systolic blood pressure = 30/min, heart rate >= 125, new confusion, oxygen saturation 10% in-hospital mortality) or ADHERE18 (high risk or intermediate risk 1)*; Severe pulmonary hypertension
• For complicated urinary tract infection: Absence of pyuria; Most recent qSOFA > 1 (SBP≤100 mmHg, RR≥22, GCS 10% mortality)
• For other infection: Most recent qSOFA > 1 (SBP≤100 mmHg, RR≥22, GCS 10% mortality)
• For COPD: BAP-65 score > 3 (BUN>25, altered mental status, HR>109, age>65) ( 190 mmHg; Evidence of end-organ damage; for example, acute kidney injury, focal neurologic deficits, myocardial infarction
• For atrial fibrillation with rapid ventricular response: Likely to require cardioversion; New atrial fibrillation with rapid ventricular response; Unstable blood pressure, respiratory rate, or oxygenation; Despite IV beta and/or calcium channel blockade in the emergency department, HR remains > 125 and SBP remains different tha
