The objective of this study was to investigate the relationship between continuity of family physician (FP) care and inpatient hospitalizations in elderly people with diabetes who have universally-insured health care. We constructed a population-based retrospective cohort study using a sample of 1143 people aged 65 years or older with newly diagnosed diabetes who were selected from a longitudinal surveillance database in the province of Newfoundland and Labrador (NL), Canada. Continuity of FP care was estimated by 3 chronological indices (Continuity of Care [COC], Usual Provider Continuity [UPC], and Sequential Continuity [SECON]) using administrative physician claims data.

Introduction: Herpes simplex virus type 1 infection usually causes a mild, self-limiting painful blistering around the mouth, with 20% to 40% of adults affected at some time. Primary infection usually occurs in childhood, after which the virus is thought to remain latent in the trigeminal ganglion. Recurrence may be triggered by factors such as exposure to bright light, stress, and fatigue.

Objective: To examine the evidence that continuity of primary care is important for older people with chronic diseases.

Data Sources: MEDLINE, EMBASE and CINAHL were searched from January 1970 to June 2005 for original articles in English that examined the relationship between interpersonal continuity of patient care and health outcomes of people 50 years old and older. Articles found were reviewed and analyzed by both authors to assess the strength of study design and the quality of the evidence provided.
