A Transitional Care Intervention Trial

A growing body of evidence suggests that the quality of health management decreases when patients are transitioned across sites of care—particularly when they are not adequately prepared to self-manage their chronic disease, when they receive conflicting advice from various providers, or when they do not have access to their healthcare providers. Higher rates of medication errors and lack of appropriate follow up compromise patient safety during this vulnerable period. This is a particular problem for hospitalists, who introduce an additional discontinuity into the flow of patient care. Because patients and their caregivers are the only common thread moving across various sites of care, this study targeted them for an intervention designed to improve the quality of transitional care.
The study was done in collaboration with a not-for-profit capitated system in Colorado. To be eligible for the study, patients had to be over age 65 and admitted to one of the participating hospitals. Patients had to be community dwelling with no documented dementia and had to have one of eleven diagnoses selected to reflect a higher likelihood of long-term subacute care or anticoagulation, including stroke, congestive heart failure, COPD, diabetes, hip fracture, coronary artery disease, and pulmonary embolism. The intervention group comprised 379 patients, while the control group was made up of 371 patients.
The intervention model was built on four pillars derived from prior qualitative studies about care transitions:
- Assistance with medication self-management;
- A healthcare record owned and maintained by the patient;
- Timely physician follow-up; and
- A list of red flags indicative of clinical deterioration.
Intervention-group patients had access to a personal health record that included an active problem list, medications, allergies, and a list of red flags; in addition, these patients received a series of visits and telephone calls with a “transition coach,” an advanced care nurse who encouraged self-care by patients and their caregivers, facilitated communication between providers and patients, and assisted in medication review and reconciliation.
The primary outcome measure was the rate of nonelective rehospitalization at 30, 90, and 180 days after discharge from the index hospitalization. Ninety-five percent of the intervention patients and 94.9% of the control subjects were included in the analysis. Intervention patients had lower adjusted hospital readmission rates than controls at 30 (8.3% versus 11.9%) and 90 days (16.7% versus 22.5%), P=0.048 and 0.04 respectively. The result did not achieve significance at 180 days after discharge (P=0.28). Rehospitalization for the same diagnosis as the index diagnosis within 90 and 180 days of admission was 5.3% in the intervention group versus 9.8% in the control group (P=0.04) and 8.6% in the intervention group versus 13.9% (P=0.045) in the control group, respectively, but did not meet statistical significance within 30 days of readmission.
The concepts of a transition coach and a patient-maintained record are enticing, considering the amount of time hospitalists may invest in patient education and discharge planning processes. This study is different from prior studies in that it used transition coaches instead of healthcare professionals to assume the primary role in managing the post-hospitalization course, and it provided the caregiver and patient with tools that could be applied to future care transitions. The costs of intervention in this study were found to be about $74,310 for the transition coach and other related costs, compared with a semi-annual cost savings of $147,797.
