ABSTRACT
BACKGROUND: Chronic kidney disease (CKD) is age-dependent and has a high prevalence in the general population. Most patients are managed in ambulatory care. This systematic review provides an updated overview of quality and content of international clinical practice guidelines for diagnosis and management of non-dialysis CKD relevant to patients in ambulatory care. METHODS: We identified guidelines published from 2012-to March 2018 in guideline portals, databases and by manual search. Methodological quality was assessed with the Appraisal of Guidelines for Research and Evaluation II instrument. Recommendations were extracted and evaluated. RESULTS: Eight hundred fifty-two publications were identified, 9 of which were eligible guidelines. Methodological quality ranged from 34 to 77%, with domains "scope and purpose" and "clarity of presentation" attaining highest and "applicability" lowest scores. Guidelines were similar in recommendations on CKD definition, screening of patients with diabetes and hypertension, blood pressure targets and referral of patients with progressive or stage G4 CKD. Definition of high risk groups and recommended tests in newly diagnosed CKD varied. CONCLUSIONS: Guidelines quality ranged from moderate to high. Guidelines generally agreed on management of patients with high risk or advanced CKD, but varied in regarding the range of recommended measurements, the need for referrals to nephrology, monitoring intervals and comprehensiveness. More research is needed on efficient management of patients with low risk of CKD progression to end stage renal disease.

BACKGROUND: Many drugs require dose adjustment or are contraindicated in patients with chronic kidney disease (CKD) to avoid adverse events. The aims of this study were to assess if medication was appropriately dose adjusted in patients with CKD in primary care, to identify medications that were frequently prescribed inappropriately and to identify factors predicting mal-prescription. METHODS: We conducted a cross-sectional observational study in 34 general practioners' offices, assessing the medication of patients with CKD stage ≥â3 according to the corresponding pharmaceutical product information. Additional information was extracted from recommendations of scientific societies and regulatory authorities. Contraindicated and overdosed medications were identified. Predictive factors for inadequate prescribing were analyzed with multiple logistic regression. RESULTS: 589 patients (Ø 78 years, 63â% female) with CKD stage ≥â3 were included. A total of 5102 medications were extracted from the medication sheets (94,6â% regular, 5,4â% "as needed"). 4,2â% were judged as being inadequate according to pharmaceutical information (2,1â% contraindicated, 2,1â% overdosed). 173 patients (29â%) had ≥â1 inadequate prescription. The proportion of inadequate prescriptions fell to 3,5â% after adjustment for the most recent recommendations of scientific societies and regulatory authorities. Most frequent inappropriate prescriptions were ACE-inhibitors, diuretics, oral antidiabetic drugs, methotrexate and potassium supplements. Most important predictors for inadequate prescriptions were CKD stage ≥â3b and number of medications. CONCLUSION: A quarter of all patients had a least one inadequate prescription. The overall proportion of inadequately prescribed drugs was low. Adjustment for recommendations by scientific societies and regulatory authorities further reduced the number of inadequate prescriptions. Valid data on the clinical relevance of inadequate prescriptions is scarce and further research is required. Because of the time and effort needed to assess all medications, future quality improvement projects should focus on CKD stage ≥â3b, patients with polypharmacy and crucial medication.
