Influence of the COVID-19 pandemic on drug and healthcare utilisation among First Nations with diabetes in Alberta, Canada: a retrospective cohort study.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectivesThe purpose of this study was to assess changes in diabetes management and healthcare utilisation among First Nations with diabetes in Alberta before and during the COVID-19 pandemic.
designThis analysis used a retrospective cohort in a case-control design. Individual-level administrative health datasets (1 April 2018 to 31 March 2022) were linked and data were formatted as a segmented interrupted time series.
settingThis study took place in Alberta, Canada using administrative data.
participantsAdult First Nations and non-First Nations (matched 1:1) with diabetes and living in Alberta were included (n=28 101; 53% female, 47% male). PRIMARY AND SECONDARY OUTCOME MEASURES: The primary outcome was the change in incidence rate of general practitioner (GP) visits, emergency department (ED) visits, hospitalisations and diabetes-related drug dispenses during-COVID-19 versus pre-COVID-19, quantified using generalised linear regressions. The secondary outcome was to report the reasons for non-drug outcomes pre-COVID-19 and during-COVID-19, based on primary diagnosis International Statistical Classification of Diseases and Related Health Problems codes.
resultsPre-COVID-19, baseline rates of GP visits, ED visits, hospitalisations and drug dispenses were significantly higher among First Nations compared with non-First Nations (rate differences 398.32 (391.97-404.67), 100.58 (98.32-102.84), 14.49 (13.56-15.43), 876.98 (868.72-885.24) per 100 person-years (PY); p<0.0001). This corresponds to rates greater by 33%, 78%, 62% and 45%, respectively (p<0.0001). These disparities generally became greater during COVID-19 (rate differences 437.21 (430.83-443.59), 91.29 (89.28-93.31), 16.90 (16.00-17.80), 1066.55 (1057.74-1075.37) per 100 PY; p<0.0001) and rates higher by 36%, 95%, 86% and 49%, respectively (p<0.0001). Among First Nations during COVID-19, the rate of ED visits and hospitalisations decreased from baseline by 17% and 2%; the rate of GP visits and drug dispenses increased by 0.54% and 15%. Non-First Nations experienced greater comparative drops in GP visits, ED visits and hospitalisations, and a smaller increase in drug dispenses. There were no discernible patterns regarding the secondary outcome.
conclusionsHealthcare utilisation was substantially elevated among First Nations compared with non-First Nations peoples before and during COVID-19. While the generalisability of our findings to other health systems and populations may be limited, our findings are clinically applicable among First Nations across Alberta in order to help direct public health programming post-COVID-19.
