Many of these older patients are frail and burdened with multiple comorbidities, raising important questions about the most appropriate and compassionate course of care. According to the Kidney Disease Improving Global Outcomes 2024 guidelines,4 conservative renal care is a reasonable option to consider for patients who do not wish to pursue KRT.  \nIn this issue of Kidney360, Kobayashi et al.5 conducted a retrospective cohort study using data from a national health examination cohort, spanning from April 2014 to May 2023. The data, provided by DeCS HealthCare Inc.(Tokyo, Japan), included health insurance claims records. The study population consisted of individuals aged 75 years or older with an eGFR of ,8 ml/min who did not receive KRT.  \nThe authors divided patients into two groups: the CKM group and the non-CKM group. The CKM group included those who underwent no procedures related to KRT, while the non-CKM group consisted of patients who had undergone procedures such as vascular access surgery or peritoneal dialysis (PD) catheter insertion.  \nFor statistical analysis, a Cox proportional hazards model was used to evaluate mortality, while age, sex, body mass index, frailty, and renal function were assessed as factors influencing CKM selection. In addition, a Poisson regression model was used to calculate incidence rate  \nratios for hospitalization. Frailty was assessed using the Electronic Frailty Index. The study found that the CKM group had significantly lower hospitalization rates compared with the non-CKM group, without any significant effect on overall survival.  \nAlthough the study addresses a clinically important and relevant issue, which is the benefit of KRT in a vulnerable elderly population, it has significant flaws and limitations that threaten its internal validity. Most notably, the study population was drawn from a health checkup database, which may not be representative of the broader population of older adults with stage 5 CKD. Individuals who undergo routine health checkups are often healthier or more health conscious than those who do not, introducing a potential selection bias. As a result, the benefits of CKM may be overestimated, since the study participants likely had fewer comorbidities and better overall health than the general elderly CKD population.  \nAnother limitation of the study is its use of administrative claims data, which often lacks detailed clinical information. Important factors such as patient preferences, clinical presentations, and the presence of uremic symptoms or heart failure were not available. The absence of this information may have led to incorrect classification of patients into the CKM or non-CKM groups and could also compromise the internal validity of the study's findings. In addition, the study did not explore the nature of care received by patients in the CKM group. For example, whether they received supportive care or palliative care. Clarifying this distinction would offer greater insight into patient well-being and the management of symptoms.  \nNephrology Division, Al Amiri Hospital, Kuwait City, Kuwait  \nCorrespondence: Dr. Abdullah Al-Muhaiteeb, email: [muhaitku@gmail.com](muhaitku@gmail.com)  \nSee related article,“Comprehensive Conservative Kidney Management among Older Population: A Nationwide Administrative Claims Database Analysis,” on pages 1713–1721.  \nCopyright © 2025 The Author(s)","cbCaioa2ZXHWd9cJ","https://ap.wps.com/l/cbCaioa2ZXHWd9cJ","pdf",153696,"English","# Editorial: Conservative Kidney Management in Elderly Patients Not Receiving Dialysis - How to Proceed?\n## Epidemiology and rationale for CKM\n## Study design and patient groupings\n## Statistical methods and key findings\n## Limitations affecting internal validity\n## CKM as an active, structured care approach\n## Clinical outcomes beyond mortality and hospitalization","[{\"question\":\"Why is conservative kidney management considered for elderly patients who do not want KRT?\",\"answer\":\"CKM is framed as a reasonable alternative under Kidney Disease Improving Global Outcomes 2024 guidance for patients who do not wish to pursue KRT.
