Peritoneal dialysis (PD) has been suggested as an effective and safe dialysis modality in patients with acute kidney injury (AKI). However, whether PD is superior to extracorporeal therapy (e.g. haemodialysis) in terms of improving survival, recovery of kidney function, metabolic and clinical outcomes is still inconclusive. The aim of this review was to evaluate the benefits and harms of PD for patients with AKI compared with extracorporeal therapy or different PD modalities. We searched the Cochrane Kidney and Transplant Register of Studies to 29 May 2017 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 Register (ICTRP) Search Portal, and ClinicalTrials.gov. We also searched the China Biological Medicine Database. We included patients with AKI who were randomised to receive PD, extracorporeal therapy, or different PD modalities regardless of their age, sex, primary disease and clinical course. Screening, selection, data extraction and quality assessments for each retrieved article were carried out by two authors using standardised forms. Authors contacted when published data were incomplete. Statistical analyses were performed using the random effects model and results expressed as risk ratio (RR) with 95% confidence intervals (CI). Heterogeneity among studies was explored using the Cochran Q statistic and the I2 test. Outcomes of interest included all-cause mortality, recovery of kidney function, weekly delivered Kt/V, correction of acidosis, fluid removal, duration of dialysis, and infectious complications. Confidence in the evidence was assessing using GRADE. Six studies (484 participants) met our inclusion criteria. Five studies compared high volume PD with daily haemodialysis, extended daily haemodialysis, or continuous renal replacement therapy. One study focused on the intensity of PD. The overall risk of bias was low to unclear. Compared to extracorporeal therapy, PD probably made little or no difference to all-cause mortality (4 studies, 383 participants: RR 1.12, 95% CI 0.81 to 1.55; I2 = 69%; moderate certainty evidence), or kidney function recovery (3 studies, 333 participants: RR 0.95, 95% CI 0.68 to 1.35; I2 = 0%; moderate certainty evidence). PD probably slightly reduces the amount of fluid removal compared to extracorporeal therapy (3 studies, 313 participants: MD -0.59 L/d, 95% CI -1.19 to 0.01; I2 = 89%; low certainty evidence), and probably made little or no difference to infectious complications (2 studies, 263 participants: RR 1.03, 95% CI 0.60 to 1.78; I2 = 0%; low certainty evidence). It is uncertain whether PD compared to extracorporeal therapy has any effects on weekly delivered Kt/V (2 studies, 263 participants: MD -2.47, 95% CI -5.17 to 0.22; I2 = 99%; very low certainty evidence), correction of acidosis (2 studies, 89 participants: RR 1.32, 95% CI 0.13 to 13.60; I2 = 96%; very low certainty evidence), or duration of dialysis (2 studies, 170 participants: MD -1.01 hours, 95% CI -91.49 to 89.47; I2 = 98%; very low certainty evidence). Heterogeneity was high and this may be due to the different extracorporeal therapies used.One study (61 participants) reported little or no difference to all-cause mortality, kidney function recovery, or infection between low and high and intensity PD. Weekly delivered Kt/V and fluid removal was lower with low compared to high intensity PD. Based on moderate (mortality, recovery of kidney function), low (infectious complications), or very low certainty evidence (correction of acidosis) there is probably little or no difference between PD and extracorporeal therapy for treating AKI. Fluid removal (low certainty) and weekly delivered Kt/V (very low certainty) may be higher with extracorporeal therapy.

Attention Score in Context

Attention Score in Context

This research output has an Altmetric Attention Score of 14. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 24 April 2020.
All research outputs
of 25,461,852 outputs
Outputs from Cochrane database of systematic reviews
of 12,090 outputs
Outputs of similar age
of 446,393 outputs
Outputs of similar age from Cochrane database of systematic reviews
of 172 outputs
Altmetric has tracked 25,461,852 research outputs across all sources so far. Compared to these this one has done well and is in the 89th percentile: it's in the top 25% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 12,090 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 38.2. This one has gotten more attention than average, scoring higher than 57% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 446,393 tracked outputs that were published within six weeks on either side of this one in any source. This one has done well, scoring higher than 87% of its contemporaries.
We're also able to compare this research output to 172 others from the same source and published within six weeks on either side of this one. This one is in the 38th percentile – i.e., 38% of its contemporaries scored the same or lower than it.
