The sociodemographic conditions of developing countries make peritoneal dialysis (PD) a cost-effective therapy for patients with Chronic Kidney Disease (CKD). Its efficacy depends on the catheter's continued good function, with catheter dysfunction being the most frequent non-infectious complication. The primary aim of this study is to describe the prevalence of peritoneal catheter dysfunction in patients from a region in Southeast Mexico, identify the main associated factors, and assess the relationship between these and the catheter dysfunction
We conducted a one-year cross-sectional study at a tertiary-level hospital in Campeche, Mexico. We included adult patients with Stage 5 CKD (KDIGO) receiving PD between June 2023 and June 2024 who developed peritoneal catheter dysfunction, defined by the ISPD as difficulty or slowness in dialysate infusion or drainage. 202 patient records were reviewed using non-probabilistic convenience sampling, resulting in a final sample of n=192 patients. Six records were excluded, and no missing data were reported, as data completeness was considered an inclusion criterion. (Figure 1)
Demographic characteristics, major comorbidities, and the number of deaths were recorded. Catheter dysfunction episodes were quantified, and associated factors including migration, fibrin obstruction, and the presence of constipation (based on Rome IV criteria) were registered. The time elapsed between catheter placement and the first dysfunction episode was considered for its relevance to outcomes.
We documented 118 patients with dysfunction, a prevalence of 61.46%. Mean age was 55.36±12.78 years (p>0.600). (Table 1)
The prevalence of dysfunction in the group with constipation (80.4%) was higher compared to the group without constipation (44.0%), yielding a Prevalence Ratio (PR) of 1.83 (IC 95%:1.43 to 2.33; p<0.05). The absolute difference in prevalence was 0.3643 (36.43%). (Table 2)
The most prevalent associated factor was Type 2 Diabetes (DM2) with a crude PR of 19.50 (IC 95%:7.46 to 50.36; p<0.001), and the time from placement to the first dysfunction reported a median of 90.0 days (Q1:48.75 to Q3:150.00 days), with an Interquartile Range (IQR) of 101.25 days. Multivariate analysis was not feasible due to methodological limitations.
In the studied population, for every 100 patients on peritoneal dialysis who presented with constipation, 36 additional cases of catheter dysfunction were observed (Prevalence Difference of 36.43%). Fifty percent of patients developed dysfunction between day 48 and day 150 following catheter placement. Patients with constipation had 1.83 times higher prevalence of dysfunction.
The primary methodological limitation is the study design, as its cross-sectional nature prevents the determination of causality, and the sample size may underestimate the true prevalence. In a context lacking epidemiological data, our results are consistent with the existing evidence, providing important information on the impact of constipation in a population segment in Southeast Mexico, representing an opportunity for improvement in the management and prevention of dysfunction focused on enhancing the quality of life for patients on peritoneal dialysis.
