C ontinuity of care occurs when patients experience linked care over time and when discrete elements of care are connected.1 Overall, most studies have shown a benefit of physician continuity, exemplified by lower utilization of emergency and hospital services, [2][3][4][5] greater use of preventive interventions, 6-8 improvements in disease-specific symptoms or quality-of-care measures, 9 and greater patient satisfaction.
10,11Continuity of care has been conceptualized as having 3 primary components:1 physician continuity, management continuity and information continuity. The root component of information continuity is the availability of data from previous visits by the patient with other physicians. In 3 previous studies, physicians were frequently missing necessary information from visits that patients had made to other physicians. [12][13][14] However, none of those studies prospectively followed a well-defined cohort of patients.To achieve a better understanding of how information exchange might be improved in the community setting, we sought to identify the patient-and physician-related factors that influence the availability of information from previous visits with other physicians.
Methods
Study designWe conducted a multicentre prospective cohort study including patients discharged to the community from medical or surgical services of 11 Ontario hospitals in 5 cities after an elective or emergent admission. The 11 hospitals consisted of 6 university-affiliated institutions and 5 community hospitals. We did not include patients who had been discharged to nursing homes. Patients were eligible for enrolment if their cognitive skills were unimpaired, if they had a telephone and if they provided written informed consent.
