Patient Awareness of CKD: A Systematic Review and Meta-analysis of Patient-Oriented Questions and Study Setting.

ABSTRACT:

Rationale & objective

Patient awareness of disease is the first step toward effective management and disease control. Awareness of chronic kidney disease (CKD) has consistently been shown to be low, but studies estimating patient awareness of CKD have used different methods. We sought to determine whether the estimated prevalence of CKD awareness differed by the wording used to ascertain awareness or by setting characteristics.

Study design

Systematic review and meta-analysis.

Setting & study populations

Adults with CKD not receiving dialysis.

Selection criteria for studies

We included studies that estimated CKD awareness, determined CKD status by laboratory criteria, and provided the exact question wording used to ascertain awareness.

Data extraction

2 reviewers independently extracted data for each study; discordance was resolved by a third independent reviewer.

Analytical approach

Mixed-effects models were used to calculate pooled CKD awareness estimates and 95% CIs.

Results

32 studies were included. Publication year ranged from 2004 to 2017, with study populations ranging from 107 to 28,923 individuals. CKD awareness in individual studies ranged from 0.9% to 94.0%. Pooled CKD awareness was 19.2% (95% CI, 10.0%-33.6%) overall and was 26.5% (95% CI, 11.9%-48.9%) among individuals with an estimated glomerular filtration rate < 60 mL/min/1.73 m². "Kidney problem" was the most sensitive question for CKD awareness (58.7%; 95% CI, 32.4%-80.8%); "weak or failing kidneys" was the least sensitive (12.3%; 95% CI, 4.5%-29.4%). CKD awareness was highest among patients from nephrology practices (86.2%; 95% CI, 74.9%-93.0%) and lowest in the general population (7.3%; 95% CI, 5.0%-10.5%).

Limitations

Significant heterogeneity across studies overall and among examined subgroups of wording and study setting.

Conclusions

Differently worded questions may lead to widely different estimates of CKD awareness. Consistent terminology is likely needed to most effectively surveil and leverage CKD awareness to improve management and disease control.

Project description:Rationale & Objective:Data from patients in one delivery system have suggested that the prevalence of chronic kidney disease (CKD) awareness differs by how the question is asked. We examined the sensitivity and specificity of different CKD awareness questions among diverse community-dwelling adults who were not necessarily engaged in primary care to determine the generalizability of prior results. Study Design:Cross-sectional study. Setting & Participants:Participants in the Healthy Aging in Neighborhoods of Diversity Across the Life Span (HANDLS) Study. Predictor:CKD awareness, ascertained using 5 different questions. Outcome:Sensitivity and specificity of each awareness question, using laboratory results as the gold standard. Analytic Approach:Logistic regression was used to compare sensitivities of different awareness questions. Results:Among 2,046 participants, mean (SD) age was 56.5 (9.1) years, 41.5% were men, and 61.3% were African American. More than 40% were poor, 35% reported not having health insurance, and 16.9% had low health literacy. More than 20% (n = 424) had CKD. Sensitivities of single CKD awareness questions ranged from 2.2% for "kidney damage" to 5.2% for "kidney problem." Sensitivity of the compound question asking about "weak kidneys, failing kidneys, or kidney disease" was 19.5%. Sensitivity of this compound CKD awareness question was higher among study participants with more advanced CKD and low health literacy, and those who lived below the poverty level. Limitations:Single measures of estimated glomerular filtration rate and albuminuria; study participants may have been more engaged in their health care than the average US adult, potentially limiting the generalizability of results. Conclusions:CKD awareness is low among community-dwelling adults with kidney disease, though data using a sensitive compound question ascertaining awareness suggest that we have met the Healthy People 2020 goal related to CKD awareness of 13.4%. Understanding the phrases about kidney disease that are most understandable to patients with and at risk for CKD is important to further increase CKD awareness.

Project description:Background and objectivesWe undertook a systematic review and meta-analysis of published cohort studies and case-control studies to estimate (1) the risk of pregnancy complications among patients with CKD versus those without CKD and (2) the risk of CKD progression among pregnant patients versus nonpregnant controls with CKD.Design, setting, participants, & measurementsWe searched electronic databases for studies published between 1946 and 2014, and we reviewed articles using validity criteria. Random-effects analytical methods were used.ResultsTwenty-three studies (14 with data for adverse pregnancy outcomes and 9 for renal outcomes) with 506,340 pregnancies were included. Pregnancy with CKD had greater odds of preeclampsia (odds ratio [OR], 10.36; 95% confidence interval [95% CI], 6.28 to 17.09), premature delivery (OR, 5.72; 95% CI, 3.26 to 10.03), small for gestational age/low birth weight (OR, 4.85; 95% CI, 3.03 to 7.76), cesarean section (OR, 2.67; 95% CI, 2.01 to 3.54), and failure of pregnancy (OR, 1.80; 95% CI, 1.03 to 3.13). Subgroup analysis showed that odds of preeclampsia (P<0.01) and premature delivery (P<0.01) were higher in women with nondiabetic nephropathy compared with diabetic nephropathy, and the odds of preeclampsia (P=0.01) and premature delivery (P<0.01) were higher in women with macroproteinuria compared with microproteinuria. The median for follow-up time for renal events was 5 years (interquartile range, 5-14.7 years). There were no significant differences in the occurrence of renal events between CKD pregnant women and those without pregnancy (OR, 0.96; 95% CI, 0.69 to 1.35). Subgroup analysis showed that publication year, sample size, follow-up years, type of primary disease, CKD classification, level of serum creatinine at baseline, proteinuria, and level of systolic BP did not modify the renal outcomes.ConclusionsThe risks of adverse maternal and fetal outcomes in pregnancy are higher for women with CKD versus pregnant women without CKD. However, pregnancy was not a risk factor for progression of renal disease in women with CKD before pregnancy.
