Gender differences in perceived pain and health-related quality of life in people with chronic non-malignant pain: a cross-sectional study.

BACKGROUND: Chronic pain has a disproportionate impact on members of vulnerable population groups, and women are at substantially greater risk than men of suffering multiple chronic pain disorders. Moreover, one of the aspects most affected by the presence of chronic pain is that of health-related quality of life (HRQoL), worsening over time, as the disease persists. OBJECTIVES: To describe the profile of patients who suffer non-malignant chronic pain, from a gender perspective, and to identify factors related to their HRQoL and mental health. DESIGN: A cross-sectional study was carried out in patients with chronic non-cancer pain. METHODS: Sociodemographic variables, pain intensity at rest and in motion, SF-36 health questionnaire, anxiety, and depression were evaluated. RESULTS: The study population consisted of 531 subjects, of whom 64.2% were women. The mean age was 52.9 (SD: 10.4) years. The pain intensity recorded on the visual analogue scale was 6 (SD: 2.7) at rest and 8 (SD: 2) in motion. Physical component score and mental component score of quality of life were worse in women vs men: 33.73 (6.77) vs 32.33 (6.20), for the physical component; 36.89 (12.77) vs 32.91 (11.51), for mental component. Anxiety, depression and pain intensity, showed poorer results in women. CONCLUSION: Gender is a factor that should be considered in assessing and managing chronic pain, due to its influence on the perception of pain, and HRQoL. IMPACT STATEMENT: Gender is an important modifier of the perception of pain, and HRQoL. To achieve a patient-centred approach, nurses should incorporate gender as a differential factor to adapt and individualize pain management and patient education.

Impact of a nurse-led intervention on quality of life in patients with chronic non-malignant pain: An open randomized controlled trial.

AIMS: To determine the effect of a comprehensive nurse-led programme for patients with chronic non-malignant pain, on quality of life, level of pain, anxiety, and depression, as primary outcomes and patients' satisfaction as a secondary end point. DESIGN: An open-label randomized controlled trial was carried out. METHODS: The experimental group received both a nurse-led intervention on healthy lifestyles, education on self-esteem, pain awareness, communication, and relaxation techniques. The control group received usual care. Quality of life, level of pain, anxiety, and depression were the main outcomes. Data were obtained at baseline, immediately after the intervention, and 6 and 9 months. The study was carried out from 2015-2017. RESULTS: The sample was composed of 279 patients. At 9 months, the effect size (non-parametric effect size statistic A) favoured the intervention group for SF-36 mental health score (A = 0.79; 95% CI: 0.73-0.85), anxiety (A = 0.58; 95% CI: 0.51-0.65), pain intensity (A = 0.57; 95% CI: 0.51-0.64), and depression (A = 0.58; 95% CI: 0.51-0.65). Smaller differences were found on physical scores between the intervention and the usual care group. Patients showed a high level of satisfaction with the introduced intervention. CONCLUSION: A comprehensive nurse-led programme for patients with chronic non-malignant pain has a positive impact on their quality of life, level of pain, and mental health. IMPACT: Studies have reported that the problem of chronic pain is not optimally controlled. A structured nurse-led programme has been tested to facilitate healthy behaviours to help patients manage their chronic pain and to provide them with the necessary tools for their self-care. This nurse-led intervention improved their mental health and decreased their level of pain.
