Abstract

BACKGROUND AND OBJECTIVES: Chronic pain (CP) affects about 30% of the global population and constitutes one of the greatest challenges for healthcare systems, generating significant physical, psychological, social, and economic impacts. From this perspective, it is imagined that pharmaceutical care, when integrated into multiprofessional teams, can reduce the intensity of pain, improve treatment adherence, and rationalize pharmacotherapy in patients with CP. The present study aimed to evaluate the effectiveness of pharmaceutical care in the management of chronic pain in patients seen at the EDUCADOR Extension Program of the Federal University of Alfenas.

METHODS: This is an observational, descriptive, quantitative, and prospective study conducted with 22 patients diagnosed with CP. The follow-up adhered to recognized clinical protocols, such as the Subjective, Objective, Plan and Assessment (SOAP) method for recording consultations, the American Society of Hospital Pharmacists (ASHP) method for reviewing pharmacotherapy, and Resolution CM. RES (2020)3 as a quality guideline. For the measurement of clinical outcomes, validated instruments were used: Brief Pain Inventory (BPI) for pain intensity and interference, Medication Regimen Complexity Index (MRCI) for prescription evaluation, ARMS Scale for drug adherence, and CPM-ES-ES for pain management perception.

RESULTS: The results demonstrated a significant reduction in pain intensity (initial median from 10.0 to 2.5 after intervention, p<0.001), as well as a decrease in the number of drugs per patient (median from 4.0 to 3.0, p<0.001). Furthermore, there was a significant improvement in adherence indicators (81%) and access to healthcare services (95%), with a substantial reduction in visits due to pain (86%).

CONCLUSION: It is concluded that pharmaceutical care, combined with multidisciplinary follow-up, significantly contributed to clinical improvement and the rationalization of pharmacotherapy, reinforcing its importance as an essential and costeffective practice in the management of CP.

Resumo

JUSTIFICATIVA E OBJETIVOS: A dor crônica (DC) afeta cerca de 30% da população mundial e constitui um dos maiores desafios para os sistemas de saúde, gerando impactos físicos, psicológicos, sociais e econômicos significativos. Nessa perspectiva, imagina-se que o cuidado farmacêutico, quando integrado a equipes multiprofissionais, seja capaz de reduzir a intensidade da dor, melhorar a adesão ao tratamento e racionalizar a farmacoterapia em pacientes com DC. O objetivo deste estudo foi avaliar a efetividade do cuidado farmacêutico no manejo da DC em pacientes atendidos pelo Programa de Extensão EDUCADOR da Universidade Federal de Alfenas.

MÉTODOS: Trata-se de um estudo observacional, descritivo, quantitativo e prospectivo, realizado com 22 pacientes diagnosticados com DC. O acompanhamento seguiu protocolos clínicos reconhecidos, como o método de dados Subjetivos, Objetivos, Avaliação e Plano de Cuidado (SOAP) para registro das consultas, o método da American Society of Hospital Pharmacists (ASHP) para revisão da farmacoterapia e a Resolução CM. RES (2020)3 como diretriz de qualidade. Para mensuração dos desfechos clínicos, foram utilizados instrumentos validados: Brief Pain Inventory (BPI) para intensidade e interferência da dor, Índice de Complexidade da Farmacoterapia (ICFT) para avaliação da prescrição, Escala ARMS para adesão farmacológica e CPM-ES-ES para percepção do manejo da dor.

RESULTADOS: Os resultados demonstraram redução significativa na intensidade da dor (mediana inicial de 10,0 para 2,5 após intervenção, p<0,001), bem como diminuição no número de fármacos por paciente (mediana de 4,0 para 3,0, p<0,001). Além disso, houve melhora relevante nos indicadores de adesão (81%) e no acesso aos serviços de saúde (95%), com redução expressiva das visitas devido à dor (86%).

CONCLUSÃO: O cuidado farmacêutico, aliado ao acompanhamento multiprofissional, contribuiu de forma significativa para a melhora clínica e a racionalização da farmacoterapia, reforçando sua importância como prática essencial e custo-efetiva no manejo da DC.
