BACKGROUND
Access to primary care is a challenge for many Canadians. Models of primary care vary widely across provinces, including arrangements for same day and after-hours access. Use of walk-in clinics and emergency departments may also vary, but data sources that allow comparison are limited.
OBJECTIVE
We use Google Trends to examine searches for walk-in clinics and emergency departments across provinces and over time in Canada, and compare results to other information about primary care access.
METHODS
We developed search strategies to capture the range of terms used for walk-in clinics (e.g. urgent care clinic, after-hours clinic) and emergency departments (e.g. ER, emergency room) across Canadian provinces. We used Google Trends to determine the frequencies of these terms relative to total search volume, and standardized search frequencies to allow comparisons across provinces and over time (2011-2018). We explored how care seeking captured by Google Trends correlates with other sources of data on primary care access by province.
RESULTS
Manitoba, British Columbia, and Nova Scotia had highest search frequency for emergency departments, and Saskatchewan, Alberta, and Ontario had the lowest. Searches for walk-in clinics were most common in the western provinces of British Columbia, Alberta, and Saskatchewan. Relative search frequency for walk-in clinics increased steadily, doubling in most provinces between 2011 and 2018. Higher search frequency for walk-in clinics was correlated with ability to get a same or next-day appointment and inversely correlated with both ED use for conditions treatable in patients’ regular place of care and having a regular medical provider. Emergency department searches were not correlated with survey data.
CONCLUSIONS
Search frequencies may reflect patient care seeking but may also be impacted by news coverage and other events, especially in the case of emergency department searches. We observe substantial interprovincial variation, and marked growth in the frequency of searches for walk-in clinics. Google Searches for walk-in clinics correlate with other measures of access, and appear to correspond to differences in policies related to walk-in clinics, advanced access, and after-hours care between provinces.
