Summary: | Objective
To determine the prevalence of diabetic peripheral neuropathic pain (DPNP) among South African adults with type 1 or type 2 diabetes.
Methods
This cross-sectional study recruited patients with diabetes from 50 institutional/private clinics. DPNP was diagnosed using Douleur Neuropathique 4 (DN4) questionnaire (score ≥4). Health-related quality-of-life (HRQoL) and sleep were assessed with EQ-5D and Daily Sleep Interference Scale (DSIS), respectively.
Results
Prevalence of DPNP was 30.3% (n = 1046). Risk of DPNP was significantly increased in people aged 50–64 years (odds ratio [OR] 1.71, 95% confidence intervals [CI] 1.21, 2.41), with diabetes for ≥10 years (OR 1.55, 95% CI 1.15, 2.08), female patients (OR 1.58, 95% CI 1.18, 2.12), and black patients (OR 1.71, 95% CI 1.19, 2.46). Mean ± SD EQ-5D and DSIS scores were 0.84 ± 0.16 and 0.83 ± 1.90, respectively, in participants without DPNP versus 0.64 ± 0.25 and 3.62 ± 2.96, respectively, in those with DPNP.
Conclusions
DPNP is widely prevalent in South Africa. Despite its negative impact on HRQoL and sleep, DPNP is inadequately treated. DN4 is an easy-to-use, validated questionnaire that can be used widely as a DPNP screening tool in clinical practice. |
