Headache-attributed burden and its impact on productivity and quality of life in Russia: structured healthcare for headache is urgently needed

Abstract

Background and purpose: The study evaluated headache-attributed burden and its impact on productivity and quality of life (QoL) in Russia. Its purpose was to support recommendations for change.

Methods: A countrywide population-based random sample of 2725 biologically unrelated adults (aged 18-65 years) in 35 cities and nine rural areas of Russia were interviewed in a door-to-door survey. The structured questionnaire enquired into symptom burden, functional disability, lost productive time and QoL (applying the WHOQoL-8 question set), as well as willingness to pay (WTP) for adequate headache treatment, if it were available.

Results: Mean lost paid-work days due to headache in the previous 3 months were 1.9 ± 4.2, and mean lost household work days were 3.4 ± 5.7. The estimated annual indirect cost of primary headache disorders was USD 22.8 billion, accounting for 1.75% of gross domestic product. QoL was reduced by all types of primary headaches. According to WHOQoL-8, it was significantly lower in those with headache on ≥15 days/month than in those with episodic headache (24.7 ± 4.6 vs. 28.1 ± 5.0; P < 0.05) and lower in those with migraine than in those with tension-type headache (TTH) (27.1 ± 4.9 vs. 28.8 ± 5.0; P < 0.05). Average WTP for adequate headache treatment was RUB 455 ± 494 per month (median RUB 300), a sum sufficient in most cases, and correlated with illness severity (higher for headache on ≥15 days/month than for migraine, and for migraine than for TTH).

Conclusions: Headache is common, burdensome and costly in Russia and, manifestly, poorly mitigated by existing healthcare. Structured healthcare services for headache need to be urgently put in place.
