BACKGROUND AND OBJECTIVES: The clinical practice of analgesia in chronic pain is often deficient or ineffective, either due to the subjectivity or presence of potentiating factors. The most common chronic pains are musculoskeletal, neuropathic, and oncological. This research aimed at understanding the aspects that intersperse the process of pain and how they interfere in quality of life.

METHODS: Descriptive, cross-sectional, exploratory study with a sample of 44 patients,15 with musculoskeletal pain, 15 with oncological pain and 14 with neuropathic pain, belonging to the Base Hospital Pain Clinic in São José do Rio Preto/SP. Data were collected through specific semi-structured interviews, self-assessment and application of instruments: Visual Analog Scale, Health-Related Quality of Life Questionnaire, Morisky and Green Drug Treatment Adherence Test, Questionnaire for Diagnosis of Neuropathic Pain, Epworth Sleepiness Scale, Tampa Kinesiophobia Scale, Beck Anxiety Inventory, and Beck Depression Inventory.

RESULTS: The data analysis revealed poor quality of life in 61.36% of the patients, and this situation was even more serious for patients with neuropathic pain. The association between quality of life and the analyzed factors was statistically significant in terms of adherence to treatment, pain levels, sleepiness, anxiety and depression. Individuals with neuropathic pain were more affected, except for kinesiophobia, which had more incidence in individuals with musculoskeletal pain.

CONCLUSION: Data revealed that all types of pain considerably decrease quality of life, and it’s more evident in individuals with neuropathic pain.

JUSTIFICATIVA E OBJETIVOS: A prática clínica no tratamento da dor crônica é frequentemente deficiente ou ineficaz, seja pela subjetividade ou pela presença de fatores potencializadores. As dores crônicas mais comuns são a musculoesquelética, a neuropática e a oncológica. Este estudo teve como objetivo conhecer os aspectos que entremeiam o processo de dor e como tal condição interfere na qualidade de vida.

MÉTODOS: Estudo descritivo, transversal e exploratório que incluiu 44 pacientes, sendo 15 com dor musculoesquelética, 15 com dor oncológica e 14 com dor neuropática. Os dados foram coletados por meio de entrevista específica semiestruturada, autoavaliação e aplicação dos instrumentos: Escala Analógica Visual, Health-related Quality of Life Questionnaire, Morisky and Green Drug Treatment Adherence Test, Questionnaire for Diagnosis of Neuropathic Pain, Epworth Sleepiness Scale, Tampa Kinesiophobia Scale, Beck Anxiety Inventory e Beck Depression Inventory.

RESULTADOS: A análise dos dados revelou baixa qualidade de vida para 61,36% dos pacientes, sendo mais grave para os portadores de dor neuropática. A associação da qualidade de vida com os fatores analisados foi estatisticamente significante quanto à adesão ao tratamento, nível de dor, sonolência, ansiedade e depressão. Os indivíduos com dor neuropática foram os mais afetados, exceto pela cinesiofobia, que teve maior ocorrência nos indivíduos com dor musculoesquelética.

CONCLUSÃO: Os três tipos de dor diminuem consideravelmente a qualidade de vida dos pacientes, sendo a redução mais evidente nos portadores de dor neuropática.
