Continuity of care in general practice in Norway

Aims: Maintaining continuity of care between doctors and patients is considered a fundamental aspect of quality in primary healthcare. In this study, we aim to examine continuity in Norway over time by computing two commonly used indicators of continuity: the St Leonard’s Index of Continuity of Care (SLICC) and the Usual Provider of Care Index (UPC). Method: We employ individual-level data, which covers all primary care consultations. This data includes the identities of each patient and physician, and we can identify each patient’s regular general practitioner (GP). The SLICC is calculated as the share of consultations conducted by the patient’s regular GP annually from 2006 to 2021. Additionally, we identify each patient’s most visited physician and compute the UPC as the share of total consultations conducted by the most visited physician during the same period. Our analysis is conducted at the national level and stratified according to the level of centrality, differentiating between areas of high, moderate, and low centrality. Results: Our findings reveal that, at the national level, SLICC and UPC exhibit remarkable stability, reaching 64 and 71 percent, respectively, in 2021. However, there is significant geographical variation, with the least central areas experiencing less continuous healthcare (SLICC at 49 percent in 2021) than patients residing in more central areas (SLICC at 68 in 2021). Conclusion: Our results demonstrate a high degree of continuity that has been stable over time. However, large geographical variations suggest that policymakers should strive to reduce geographical disparities in healthcare quality.
