Gender differences in pain prevalence, characteristics, assessment and treatment in internal medicine patients: a post-hoc analysis of the FADOI-DOMINO study

Conflicting results come from epidemiological studies on the correlations between gender and pain in hospitalized patients. No specific data are reported in patients admitted to Internal Medicine Units (IMUs). Post-hoc analysis of the FADOI-DOMINO study, performed in 26 IMUs in Italy, with two cross-sectional surveys interspersed with an educational program. The 5200 medical charts of the FADOI-DOMINO study were re-analyzed. The following sex differences were highlighted: i) a greater pain prevalence was evidenced in women in the Pre-phase; ii) among patients with chronic pain, anxiety and depression were significantly more present in women compared with men; iii) oncologic pain was more prevalent in men; in a specular way, non-oncologic pain showed a greater prevalence in women in both phases; iv) strong opioids therapy was higher for men. Some sex differences in pain seem to exist in IMUs, although less evident if compared with those previously reported in other settings. A more careful assessment of coexisting conditions such as anxiety, depression or cognitive impairment can result in a better management of these problems.
