Demographic Pattern and Clinical Characteristics of Patients Undergoing Haemodialysis in a Tertiary Centre of a Developing Country: A Review of 280 Cases

Abstract

BACKGROUND: Globally, renal replacement therapy especially haemodialysis remains pivotal in the effective care of patients with kidney diseases since its acceptance as a treatment modality. Despite being widely embraced as a therapeutic option, several factors still hamper its utilization. A clinical audit of this modality option will allow elucidation of haemodialysis practises and peculiarities.

METHODS: The charts and records of 280 patients with renal impairments dialyzed between March 1^st 2019 and February 28^th 2023 were evaluated in retrospect. Data on retrieved demographic and clinical information were analyzed using SPSS 25 and patients’ short-term survival was determined using the Kaplan Meier survival analysis and log rank test.

RESULTS: Out of the 280 patients who had 1716 dialysis sessions, 184 (65.7%) were males. The mean age was 47.9 ± 17.5 years. The majority (80.7%) of the patients had chronic kidney disease (CKD), as 90.2% of the dialysis sessions were for CKD. There was a male preponderance (69.1%) in the population. Hypertension was the commonest cause of CKD (41.2%) while sepsis was the commonest cause of acute kidney injury (50%). The median number of dialysis session was 4.0. The mean pre-dialysis hematocrit was 24.4 ± 7.1% and the mean single pool Kt/V was 0.9 ± 0.02. The femoral vein was the most used vascular access (95.4%). The short-term survival was positively related to the dialysis frequency on Kaplan-Meier analysis.

CONCLUSION: Haemodialytic therapy in patients with renal disease is still of huge impact on survival despite the numerous factors affecting its effective delivery, especially in low-income nations.
