Association of kidney function impairment with healthcare service utilisation in individuals with type 2 diabetes: an observational follow-up study in primary care.

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
backgroundType 2 diabetes (T2D) causes a major burden on healthcare and is a leading cause of chronic kidney disease (CKD). While the healthcare service utilisation of individuals with CKD in speciality clinics and the high costs of renal replacement therapy have been widely studied, the burden of kidney function impairment on primary healthcare remains understudied. In this study, we aimed to examine the association of kidney function impairment with primary healthcare service utilisation in individuals with T2D.
methodsThis observational follow-up study consisted of 4773 individuals with T2D treated in the municipal Rovaniemi healthcare centre, Rovaniemi, Finland between 2011 and 2019 (mean age 70.9 years; 53.5% males). The mean follow-up period was 5.6 years. Substantial kidney function impairment was defined as a reduction of 25% or more in the estimated glomerular filtration rate (eGFR) over the follow-up and was contrasted to non-substantial kidney function impairment (eGFR reduction of less than 25%). Primary healthcare service utilisation included planned diabetes appointments, unplanned general practice [GP] appointments, other GP contacts (digital, phone or letter), unplanned nurse appointments, other nurse contacts (digital, phone or letter) and inpatient days in the healthcare centre that occurred during the follow-up. The association between kidney function impairment and primary healthcare service utilisation was studied with negative binomial regression models adjusted for potential confounding factors.
resultsSubstantial kidney function impairment occurred in 12.9% of the study population. Compared to non-substantial kidney function impairment, substantial kidney function impairment associated with increased primary healthcare service utilization when measured with planned diabetes appointments (adjusted incidence rate ratio [aIRR] 1.18, 95% confidence interval [CI] 1.09–1.28), other GP contacts (aIRR 1.38, 95% CI 1.57–1.84), unplanned nurse appointments (aIRR 1.19, 95% CI 1.02–1.24), and inpatient days in the healthcare centre (aIRR 1.20, 95% CI 1.10–1.45).
conclusionsKidney function impairment in individuals with T2D was associated with an increase in primary healthcare service utilisation in several measured categories. This further underlines the importance of prevention and prompt treatment of CKD in individuals with T2D to reduce the burden on primary healthcare.
