Glucagon-like peptide 1 (GLP-1) receptor agonists for people with chronic kidney disease and diabetes.
Approximately 40% of people with diabetes develop kidney failure and experience an accelerated risk of cardiovascular complications. Glucagon-like peptide 1 (GLP-1) receptor agonists are glucose-lowering agents that manage glucose and weight control.
We assessed the benefits and harms of GLP-1 receptor agonists in people with chronic kidney disease (CKD) and diabetes.
The Cochrane Kidney and Transplant Register of Studies was searched to 10 September 2024 through contact with the Information Specialist using search terms relevant to this review. Studies in the Register are identified through searches of CENTRAL, MEDLINE, and EMBASE, conference proceedings, the International Clinical Trials Registry Platform (ICTRP) Search Portal, and ClinicalTrials.gov.
Randomised controlled studies were eligible if participants with diabetes and CKD were randomly allocated to a GLP-1 receptor agonist, placebo, standard care or a second glucose-lowering agent. CKD included all stages (from 1 to 5).
Three authors independently extracted data and assessed the risk of bias using the risk of bias assessment tool 2. Pooled analyses using summary estimates of effects were obtained using a random-effects model, and results were expressed as risk ratios (RR) and/or hazard ratio (HR) and their 95% confidence intervals (CI) for dichotomous outcomes and mean difference (MD) and 95% CI for continuous outcomes. The primary outcomes included death (all-cause and cardiovascular), 3- and 4-point major adverse cardiovascular events (MACE), kidney failure, composite kidney outcome, and severe hypoglycaemia. The secondary outcomes included non-fatal or fatal myocardial infarction (MI) or stroke, non-fatal peripheral arterial events, heart failure, hospitalisation due to heart failure, estimated glomerular filtration rate or creatinine clearance, doubling of serum creatinine, urine albumin-to-creatinine ratio, albuminuria progression, vascular access outcomes, body weight, body mass index, fatigue, life participation, peritoneal dialysis infection, peritoneal dialysis failure, adverse events, serious adverse events, withdrawal due to adverse events, HbA1c, sudden death, acute MI, ischaemic stroke, and coronary revascularisation. Confidence in the evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach.
Forty-two studies involving 48,148 participants were included. All studies were conducted on people with type 2 diabetes, and no studies were carried out on children. The median study age was 66 years. The median study follow-up was 26 weeks. Six studies were conducted in people with CKD stages 1-2, 11 studies in people with CKD stages 3-5, one study in people on dialysis, and the remaining studies included people with both CKD stages 1-2 and 3-5. Risks of bias in the included studies for all the primary outcomes in studies that compared GLP-1 receptor agonists to placebo were low in most methodological domains, except one study that was assessed at high risk of bias due to missing outcome data for death (all-cause and cardiovascular). The overall risk of bias for all-cause and cardiovascular death in studies that reported the treatment effects of GLP-1 receptor agonists compared to standard care, dipeptidyl peptidase-4 (DPP-4) inhibitors or sodium-glucose cotransporter 2 (SGLT2) inhibitors were assessed as unclear or at high risk of bias due to deviations from intended interventions or missing data. For GLP-1 receptor agonists compared to insulin or another GLP-1 receptor agonist, the risk of bias for all-cause and cardiovascular death was low or unclear. Compared to placebo, GLP-1 receptor agonists probably reduced the risk of all-cause death (RR 0.85, 95% CI 0.74 to 0.98; I2 = 23%; 8 studies, 17,861 participants; moderate-certainty evidence), but may have little or no effect on cardiovascular death (RR 0.84, 95% CI 0.68 to 1.05; I2 = 42%; 7 studies, 17,801 participants; low-certainty evidence). Compared to placebo, GLP-1 receptor agonists probably decreased 3-point MACE (RR 0.84, 95% CI 0.73 to 0.98; I² = 65%; 4 studies, 19,825 participants; moderate-certainty evidence), and 4-point MACE compared to placebo (RR 0.77, 95% CI 0.67 to 0.89; 1 study, 2,158 participants; moderate-certainty evidence). Based on absolute risks of clinical outcomes, it is likely that GLP-1 receptor agonists prevent all-cause death in 52 people with CKD stages 1-2 and 116 in CKD stages 3-5, cardiovascular death in 34 people with CKD stages 1-2 and 71 in CKD stages 3-5, while 95 CKD stages 1-2 and 153 in CKD stages 3-5 might experience a major cardiovascular event for every 1000 people treated over 1 year. Compared to placebo, GLP-1 receptor agonists probably had little or no effect on kidney failure, defined as starting dialysis or kidney transplant (RR 0.86, 95% CI 0.66 to 1.13; I2 = 0%; 3 studies, 4,134 participants; moderate-certainty evidence), or on composite kidney outcomes (RR 0.89, 95% CI 0.78 to 1.02; I2 = 0%; 2 studies, 16,849 participants; moderate-certainty evidence). Compared to placebo, GLP-1 receptor agonists may have little or no effect on the risk of severe hypoglycaemia (RR 0.82, 95% CI 0.54 to 1.25; I2 = 44%; 4 studies, 6,292 participants; low-certainty evidence). The effects of GLP-1 receptor agonists compared to standard care or other hypoglycaemic agents were uncertain. No studies evaluated treatment on risks of fatigue, life participation, amputation or fracture.
GLP-1 receptor agonists probably reduced all-cause death but may have little or no effect on cardiovascular death in people with CKD and diabetes. GLP-1 receptor agonists probably lower major cardiovascular events, probably have little or no effect on kidney failure and composite kidney outcomes, and may have little or no effect on the risk of severe hypoglycaemia in people with CKD and diabetes.

Falls prevention interventions for community-dwelling older adults: systematic review and meta-analysis of benefits, harms, and patient values and preferences.
About 20-30% of older adults (≥ 65 years old) experience one or more falls each year, and falls are associated with substantial burden to the health care system, individuals, and families from resulting injuries, fractures, and reduced functioning and quality of life. Many interventions for preventing falls have been studied, and their effectiveness, factors relevant to their implementation, and patient preferences may determine which interventions to use in primary care. The aim of this set of reviews was to inform recommendations by the Canadian Task Force on Preventive Health Care (task force) on fall prevention interventions. We undertook three systematic reviews to address questions about the following: (i) the benefits and harms of interventions, (ii) how patients weigh the potential outcomes (outcome valuation), and (iii) patient preferences for different types of interventions, and their attributes, shown to offer benefit (intervention preferences).
We searched four databases for benefits and harms (MEDLINE, Embase, AgeLine, CENTRAL, to August 25, 2023) and three for outcome valuation and intervention preferences (MEDLINE, PsycINFO, CINAHL, to June 9, 2023). For benefits and harms, we relied heavily on a previous review for studies published until 2016. We also searched trial registries, references of included studies, and recent reviews. Two reviewers independently screened studies. The population of interest was community-dwelling adults ≥ 65 years old. We did not limit eligibility by participant fall history. The task force rated several outcomes, decided on their eligibility, and provided input on the effect thresholds to apply for each outcome (fallers, falls, injurious fallers, fractures, hip fractures, functional status, health-related quality of life, long-term care admissions, adverse effects, serious adverse effects). For benefits and harms, we included a broad range of non-pharmacological interventions relevant to primary care. Although usual care was the main comparator of interest, we included studies comparing interventions head-to-head and conducted a network meta-analysis (NMAs) for each outcome, enabling analysis of interventions lacking direct comparisons to usual care. For benefits and harms, we included randomized controlled trials with a minimum 3-month follow-up and reporting on one of our fall outcomes (fallers, falls, injurious fallers); for the other questions, we preferred quantitative data but considered qualitative findings to fill gaps in evidence. No date limits were applied for benefits and harms, whereas for outcome valuation and intervention preferences we included studies published in 2000 or later. All data were extracted by one trained reviewer and verified for accuracy and completeness. For benefits and harms, we relied on the previous review team's risk-of-bias assessments for benefit outcomes, but otherwise, two reviewers independently assessed the risk of bias (within and across study). For the other questions, one reviewer verified another's assessments. Consensus was used, with adjudication by a lead author when necessary. A coding framework, modified from the ProFANE taxonomy, classified interventions and their attributes (e.g., supervision, delivery format, duration/intensity). For benefit outcomes, we employed random-effects NMA using a frequentist approach and a consistency model. Transitivity and coherence were assessed using meta-regressions and global and local coherence tests, as well as through graphical display and descriptive data on the composition of the nodes with respect to major pre-planned effect modifiers. We assessed heterogeneity using prediction intervals. For intervention-related adverse effects, we pooled proportions except for vitamin D for which we considered data in the control groups and undertook random-effects pairwise meta-analysis using a relative risk (any adverse effects) or risk difference (serious adverse effects). For outcome valuation, we pooled disutilities (representing the impact of a negative event, e.g. fall, on one's usual quality of life, with 0 = no impact and 1 = death and ~ 0.05 indicating important disutility) from the EQ-5D utility measurement using the inverse variance method and a random-effects model and explored heterogeneity. When studies only reported other data, we compared the findings with our main analysis. For intervention preferences, we used a coding schema identifying whether there were strong, clear, no, or variable preferences within, and then across, studies. We assessed the certainty of evidence for each outcome using CINeMA for benefit outcomes and GRADE for all other outcomes.
A total of 290 studies were included across the reviews, with two studies included in multiple questions. For benefits and harms, we included 219 trials reporting on 167,864 participants and created 59 interventions (nodes). Transitivity and coherence were assessed as adequate. Across eight NMAs, the number of contributing trials ranged between 19 and 173, and the number of interventions ranged from 19 to 57. Approximately, half of the interventions in each network had at least low certainty for benefit. The fallers outcome had the highest number of interventions with moderate certainty for benefit (18/57). For the non-fall outcomes (fractures, hip fracture, long-term care [LTC] admission, functional status, health-related quality of life), many interventions had very low certainty evidence, often from lack of data. We prioritized findings from 21 interventions where there was moderate certainty for at least some benefit. Fourteen of these had a focus on exercise, the majority being supervised (for > 2 sessions) and of long duration (> 3 months), and with balance/resistance and group Tai Chi interventions generally having the most outcomes with at least low certainty for benefit. None of the interventions having moderate certainty evidence focused on walking. Whole-body vibration or home-hazard assessment (HHA) plus exercise provided to everyone showed moderate certainty for some benefit. No multifactorial intervention alone showed moderate certainty for any benefit. Six interventions only had very-low certainty evidence for the benefit outcomes. Two interventions had moderate certainty of harmful effects for at least one benefit outcome, though the populations across studies were at high risk for falls. Vitamin D and most single-component exercise interventions are probably associated with minimal adverse effects. Some uncertainty exists about possible adverse effects from other interventions. For outcome valuation, we included 44 studies of which 34 reported EQ-5D disutilities. Admission to long-term care had the highest disutility (1.0), but the evidence was rated as low certainty. Both fall-related hip (moderate certainty) and non-hip (low certainty) fracture may result in substantial disutility (0.53 and 0.57) in the first 3 months after injury. Disutility for both hip and non-hip fractures is probably lower 12 months after injury (0.16 and 0.19, with high and moderate certainty, respectively) compared to within the first 3 months. No study measured the disutility of an injurious fall. Fractures are probably more important than either falls (0.09 over 12 months) or functional status (0.12). Functional status may be somewhat more important than falls. For intervention preferences, 29 studies (9 qualitative) reported on 17 comparisons among single-component interventions showing benefit. Exercise interventions focusing on balance and/or resistance training appear to be clearly preferred over Tai Chi and other forms of exercise (e.g., yoga, aerobic). For exercise programs in general, there is probably variability among people in whether they prefer group or individual delivery, though there was high certainty that individual was preferred over group delivery of balance/resistance programs. Balance/resistance exercise may be preferred over education, though the evidence was low certainty. There was low certainty for a slight preference for education over cognitive-behavioral therapy, and group education may be preferred over individual education.
To prevent falls among community-dwelling older adults, evidence is most certain for benefit, at least over 1-2 years, from supervised, long-duration balance/resistance and group Tai Chi interventions, whole-body vibration, high-intensity/dose education or cognitive-behavioral therapy, and interventions of comprehensive multifactorial assessment with targeted treatment plus HHA, HHA plus exercise, or education provided to everyone. Adding other interventions to exercise does not appear to substantially increase benefits. Overall, effects appear most applicable to those with elevated fall risk. Choice among effective interventions that are available may best depend on individual patient preferences, though when implementing new balance/resistance programs delivering individual over group sessions when feasible may be most acceptable. Data on more patient-important outcomes including fall-related fractures and adverse effects would be beneficial, as would studies focusing on equity-deserving populations and on programs delivered virtually.
