Brief Summary

Hospital readmissions are common, costly, and potentially preventable. They are also potentially responsive to health system interventions. However, it is uncertain which components of care transition interventions are efficacious, for which populations, and at what cost. This randomized controlled study is part of a larger project that will evaluate a three-tiered quality improvement (QI) intervention intended to reduce hospital readmissions within 30 days post-discharge from an urban safety net hospital that serves a racially and linguistically diverse population (the randomized controlled study evaluates Tier 3). Few studies have evaluated care transition interventions to reduce readmissions among low-income, diverse patient populations, and the accumulated evidence on the effects of these multi-faceted interventions on readmission rates has been inconclusive. This project will take advantage of a unique sequence of three QI innovations to reduce hospital readmissions implemented beginning in 2007 in an integrated safety net health care system. The "discharge-transfer" tiers are as follows: 1) Tier 1 includes a comprehensive, individualized home care plan (HCP) reviewed by the medical service floor nurse with the patient prior to discharge; 2) Tier 2 adds the electronic transmission of the HCP to the patient's primary care medical home where, on the business day following discharge, a Registered Nurse makes an outreach telephone call to the discharged patient to confirm comprehension of the HCP and to address medical questions or needs; 3) Tier 3 further adds a community health worker, the Patient Navigator, to participate in bedside discussions to develop rapport and learn about patients' home situations, weekly outreach calls to assess patients' needs and to facilitate communication between the patient and the primary care team, and reminder calls to patients prior to all medical appointments to eliminate barriers to outpatient follow-up. The Aim of the study being registered is to evaluate the effects of an ongoing randomized natural experiment on readmissions, health care use, adherence to medication instructions, and preparedness for discharge. This natural experiment features random assignment to one of two QI interventions, Tier 2 or Tier 3, and exclusively targets patients at high risk for readmission, those with one or more of the following risk factors for readmission: discharge diagnosis of congestive heart failure or COPD; length of stay \> 3 days; age \> 60; or previous hospitalization within the past six months.

The investigators hypothesize that the Patient Navigator intervention (Tier 3) compared to usual care (Tier 2) will increase the rates of 30-day post-discharge PCP visits; reduce 30-day hospital readmission rates; and reduce the total number of days in hospital in the 180 days following the index admission for high risk patients. The investigators further expect that the PN intervention will improve patient adherence to medication instructions in the HCP and reduce the probability of reported problems with post-discharge care.

Primary Outcome Measures

Name	Time	Method
Hospital readmission	30 days	Inpatient readmission for any reason within 30 days of the index discharge;

Secondary Outcome Measures

Name	Time	Method
Primary and specialty care visit	Number of days to first PCP or specialist visit post-discharge; number of PCP or specialist visits within 7, 15, and 30 days post-discharge	Number of days to first PCP visit post-discharge; number of days to first PCP or specialist visit post-discharge; number of PCP or specialist visits within 7, 15, and 30 days post-discharge
Emergency department visit	30 days	Any ED visit within 30 days post-discharge; Number of ED visits within 30 days post-discharge
Adherence to medication instructions in Home Care Plan	Up to 30 days post-discharge	A binary indicator of patient adherence to prescription medication instruction in the discharge plan
Patient preparedness for discharge; problems with post-discharge care	Up to 30 days post-discharge	Satisfaction with inpatient preparation for discharge; receipt of specific written care plan instructions and contact information; satisfaction with understanding of condition, medications, and follow-up appointments; confidence in self-management of post-discharge care; problems with post-discharge care
Costs	within 180 days of discharge	We will compare the cost per patient of the PN intervention vs usual care from the perspective of Cambridge Health Alliance. Costs will be measured for each patient's 180 days post-discharge and will include Patient Navigator labor, interpreter services, primary care RN labor, and estimated patient care revenues/costs paid for each billable service utilized for study patients using the Medicare fee schedule.
hospital readmission	15 and 180 days	Readmission within 15 and 180 days of the index discharge; number of days until first readmission; total number of hospital days in the 180 days post-discharge; readmission before first scheduled PCP or specialist follow-up visit
