Background and aims

Patients with chronic kidney disease (CKD) often have comorbid anaemia [1]. Real-world data on patient characteristics, disease burden, and treatment management for people with anaemia of CKD in the Middle East and Africa are limited.

Methods

SATISFY (Survey on treatment patterns in Anemia of CKD, patient Treatment satISFaction and perspectives as reported by patients with phYsicians) was a real-world survey conducted between 01 June to 01 September 2022 in Egypt, Saudi Arabia, South Africa, and Turkey. Physician and patient perceptions of treatment were captured via cross-sectional surveys; patients’ clinical characteristics were recorded by physicians in electronic case report forms via retrospective review of medical records. Eligible physicians were nephrologists with ≥1 years’ experience who managed ≥12 patients with anaemia of CKD per month and with drug management experience for anaemia of CKD. Physicians collected data on the first 7–10 patients seen in routine clinical practice during the study period. Eligible patients were ≥18 years with CKD stage 3b, 4, or 5 at the time of anaemia of CKD diagnosis and with ≥2 years’ follow-up data from diagnosis to time of survey. Patients with functioning kidney transplants or acute kidney injury were excluded. Primary outcomes were to describe clinical and demographic characteristics, monitoring test results, treatment patterns of patients with anaemia of CKD, physicians’ reasons for not treating anaemia of CKD, and physicians’ and patients’ reasons for therapy choice. Data were analysed descriptively.

Results

A total of 1788 patients and 217 physicians were included; 1138 patients (64%) were non-dialysis dependent (NDD) and 611 (34%) were dialysis dependent (DD) at the time of data extraction (n = 39 [2%] data missing). Mean (standard deviation [SD]) age was 46 (14) years, mean (SD) body mass index was 24.1 (3.1) kg/m2, 56% (n = 1004) were male, and median (interquartile range [IQR]) follow-up from diagnosis of anaemia of CKD was 2.6 (2.5–3.2) years. The most common comorbidities were hypertension (n = 858, 48%) and diabetes (n = 324, 18%). Symptom burden was high, with lack of energy and fatigue being among the most commonly reported symptoms by physicians and patients across both NDD and DD groups (Figure 1). Differences were seen between physician and patient symptom reporting and between NDD and DD groups. Patients’ self-reported symptom burden was greater than that reported by physicians, particularly for NDD patients. The median (IQR) times per year physicians reported testing CKD patients for anaemia was 4 (4–6) for NDD patients and 12 (10–12) for DD patients. Median test levels for haemoglobin at which patients were diagnosed were lower than those reported by physicians as being used for diagnosis; similar results were seen for thresholds used to initiate treatment (Table 1). Median (IQR) days from diagnosis to first treatment was 61 (0–419). Of those who received treatment, the most common first treatment option was erythropoietin-stimulating agents + intravenous iron for both patients with NDD and DD anaemia of CKD at diagnosis (NDD n = 291/736, 40%; DD n = 170/316, 54%). A large proportion of patients never received treatment for anaemia of CKD (n = 701, 39%). The most important reasons to not initiate treatment from a physician perspective were patient refusal (n = 172, 79%) and risk of adverse reactions (n = 168, 77%); for patients, top reasons were that their symptoms were not severe (n = 168, 22%) and their physicians’ concerns about adherence (n = 116, 15%). Similar reasons were seen for both the Middle East and Africa regions.

Conclusion

Symptom burden is high in patients with anaemia of CKD in the Middle East and Africa, particularly lack of energy and fatigue. Differences were seen between physician and patient perceptions of symptom burden and between NDD and DD groups. Substantial treatment inertia exists. Physicians rated patient refusal and risk of adverse reactions as main reasons for not treating patients, while patients attributed this to a belief that their symptoms were not severe.
