Zusammenfassung: | The prevalence of chronic kidney disease (CKD) is increasing globally. Early diagnosis in primary care may have a role in ensuring proper intervention. We aimed to determine the prevalence and outcome of CKD in primary care.
We performed an observational cohort study in primary care in Copenhagen (2001-2015). Outcomes were stroke, myocardial infarction (MI), heart failure (HF), peripheral artery disease (PAD), all-cause- and cardiovascular mortality. We combined individuals with normal kidney function and CKD stage 2 as reference. We conducted cause-specific Cox proportional regressions to calculate the hazard ratios for outcomes according to CKD group. We explored the associations between kidney function and the outcomes examined using eGFR as a continuous variable modelled with penalised splines. All models were adjusted for age, gender, diabetes, hypertension, existing CVD, heart failure, LDL cholesterol and use of antihypertensive treatment.
We included 171,133 individuals with at least two eGFR measurements of which the majority (n = 157,002) had eGFR > 60 ml/min/1.73m
at index date, and 0.05% were in CKD stage 5. Event rates were low in eGFR > 60 ml/min/1.73m
but increased in those with higher stages of CKD. In adjusted analyses we observed an increase in hazard rates for every outcome with every increment in CKD stage. Compared to the reference group, individuals in CKD stage 4 had double the hazard rate of PAD, MI, cardiovascular and all-cause mortality.
Our data from a large primary care cohort demonstrate an early increase in the risk of adverse outcomes already at CKD stage 3. This underlines the importance of studying early intervention in primary care. |
