TL;DR

In a single-center randomized controlled trial of 34 hemodialysis patients with excess fluid volume, a structured 13-activity nursing intervention added to usual care improved some biochemical parameters and maintained dialysis adequacy compared with usual care. The abstract reports significant between-group effects for calcium, post-hemodialysis urea, and creatinine, while URR and Kt/V deteriorated in controls and were maintained in the intervention group.

Key findings

  • Among 34 randomized patients (intervention n=17, control n=17), the abstract reports significant between-group differences in mean calcium (p<0.001), post-hemodialysis urea (p=0.002), and creatinine (p=0.006), attributed to the intervention.
  • Dialysis adequacy: overall URR fell from 73.3±7.4 to 69.7±12.9 (p=0.001), driven by the control group (72.2±8.7 to 66.6±16.9, p=0.003), while the intervention group maintained URR (74.4±5.9 to 72.8±5.8, p=0.130). Kt/V fell overall from 1.6±0.3 to 1.5±0.4 (p=0.001), with controls declining from 1.6±0.4 to 1.4±0.5 (p<0.001) and the intervention group maintaining 1.6±0.3 (p=0.521); post-intervention between-group Kt/V approached significance (p=0.056).
  • Calcium mean increased from 9.1±0.5 to 9.4±0.2 (p<0.001) and remained within normal range; post-hemodialysis urea increased from 32.4±14.1 to 39.0±19.9 (p<0.001); creatinine increased from 8.9±3.1 to 9.7±3.0 (p=0.002).
  • Hematocrit and hemoglobin showed significant baseline differences (hematocrit 43.3±4.1 control vs 37.1±5.0 intervention, p<0.001; hemoglobin 13.2±1.3 vs 11.6±1.6, p=0.002), with no significant post-intervention differences (p=0.104 and p=0.373). Anemia prevalence increased in controls (17.6% to 29.4%) versus intervention (47% to 52.9%), p=0.006; altered hemoglobin increased in controls (23%) versus decreased in intervention (11.8%), p=0.017.

Methods

  • Randomized, double-blind, parallel-group controlled trial conducted in a Brazilian dialysis center from August 2022 to May 2023; 34 patients with chronic kidney disease and a nursing diagnosis of Excess Fluid Volume undergoing chronic hemodialysis were randomized 1:1 to intervention (n=17) or control (n=17). No formal sample size calculation was conducted; a convenience sample of all eligible patients from a finite population was used.
  • The intervention consisted of 13 nursing activities, including daily weighing, intake/output records, laboratory monitoring, hemodynamic and vital sign monitoring, edema assessment, fluid distribution, health education, caregiver guidance, and alerting the medical team to worsening fluid overload; the control group received only usual care.
  • Analyses compared groups and within-group changes using Fisher’s exact test, Mann-Whitney test, McNemar’s test, and Wilcoxon test; linear regression adjusted for furosemide use as a potential confounder; significance level was α=5%; Stata version 13 was used.

Limitations

  • Stated: the authors could not calculate patients’ GFR for within- or between-group comparison; other tests such as serum glucose were not analyzed because not all patients underwent the same non-routine tests; laboratory results were provided by the dialysis center and other blood components could not be included.
  • Stated/evident: no formal sample size calculation and a small convenience sample (n=34); baseline imbalances existed in hematocrit/hemoglobin and carvedilol 25 mg use (1 control vs 8 intervention, p=0.017), though the authors state carvedilol did not influence outcomes.
  • Evident: single-center design and short intervention/outcome window (one-month intervention phase; dialysis quality assessed over 12 hemodialysis sessions after the intervention date) limit generalizability; participants were aware of group allocation due to the intervention’s nature, although outcome assessors and the statistician were blinded.

Self-check

Percentages, sums and reported differences re-computed from the paper’s own numbers.

Each contradiction between two passages listed here was confirmed by an independent check.

  • Within-group calcium result is described as a between-group difference

    Major

    The cited p<0.001 is the overall intragroup comparison in Table 2. The table reports p=0.693 for the between-group comparison of outcome calcium means.

  • Conclusion calls the between-group mean URR result significant

    Major

    The conclusion cites a statistically significant between-group mean URR result, but Table 2 reports p=0.102 for the outcome comparison of URR means.

  • Conclusion calls the between-group mean Kt/V result significant

    Major

    The conclusion cites a statistically significant between-group mean Kt/V result, but Table 2 reports p=0.056 for the outcome comparison.

  • Within-control-group creatinine result is described as a between-group difference

    Major

    Table 2 assigns p=0.006 to the control group's intragroup creatinine comparison, whereas the between-group comparison of outcome means is p=0.340.

  • B+ blood-type percentage does not match its count

    Minor

    Five of 34 participants is 14.7% to one decimal place, not the reported 14.2%.

    Reported 14.2 · recomputed 14.705882

  • The reported predominant sex is reversed

    Minor

    The text says women made up 61.8% of the sample, but Table 1 assigns 61.8% to men and 38.2% to women.

  • Hemoglobin category lists one patient as 55.9%

    Minor

    One patient out of the control group's 17 is 5.9%, not 55.9%.

    Reported 55.9 · recomputed 5.882353

  • One control patient with decreased post-HD urea is listed as 2.9%

    Minor

    The baseline control group has 17 patients, so one patient represents 5.9%, not 2.9%.

    Reported 2.9 · recomputed 5.882353

  • Hematocrit prevalence difference is assigned a mean-comparison p-value

    Minor

    The cited p=0.006 belongs to the control group's intragroup comparison of hematocrit means. Table 2 reports p=0.296 for the between-group comparison of the outcome hematocrit categories discussed in the sentence.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Claims read by deepseek-v4.1-flash under definition version 3 (extract-v3) on 2026-10-27.

Classified by jev-1.13-20260917 (gold-guideline-v0.2) on 2026-10-27.

Cited sources are checked by gpt-6-sol.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
