RESUMO

OBJECTIVE: to evaluate the effect of nurse-performed enhanced patient education sessions on adequate bowel preparation and cecal intubation rates. METHOD: a prospective, quasi-experimental, comparative study with a quantitative approach. The intervention group (n=150) received education enhanced by a visual presentation and reminder calls. The control group (n=156) received the clinic's standard written instructions. Adequate bowel preparation rates and other colonoscopy quality indicators were compared between the groups. RESULTS: Boston Bowel Preparation scale scores and adequate bowel preparation rates were higher in the intervention group than in the control group (respectively, 6.76±2.1 vs. 5.56±2.4, p=0.000, and 80% vs. 69.2%, p=0.031). The cecal intubation rates were higher in the intervention group (80% vs. 67.3%, p=0.012). Due to inadequate bowel preparation, unsuccessful cecal intubation rates were 0% in the intervention group and 17.6% in the control group. Biopsy rates were higher in the intervention group (28% vs. 13.3%, p=0.002). CONCLUSION: the nurse-performed enhanced patient education sessions increase adequate bowel preparation rates and, in parallel, cecal intubation rates. To reach the colonoscopy quality standards recommended in the guidelines, it is suggested that patient education be supported by different training tools and given by health professionals.

RESUMO

Resumo Objetivo: avaliar o efeito da educação aprimorada realizada por enfermeiros no preparo intestinal adequado e na taxa de intubação cecal. Método: estudo prospetivo, quasi-experimental e comparativo com abordagem quantitativa. Os pacientes no grupo de intervenção (n=150) receberam a educação aprimorada e telefonemas para lembrá-los do procedimento. O grupo de controle (n=156) recebeu as instruções padrão da clínica por escrito. As taxas de preparo intestinal adequado e outros indicadores da qualidade da colonoscopia foram comparadas entre os grupos. Resultados: as pontuações obtidas na Boston Bowel Preparation Scale e a taxa de preparo intestinal adequado foram maiores no grupo de intervenção do que no grupo de controle (6,76±2,1 vs. 5,56±2,4, p=0,000, e 80% vs. 69,2%, p=0,031). A taxa de intubação cecal foi mais alta no grupo de intervenção (80% vs. 67,3%, p=0,012). A taxa de intubação cecal malsucedida devido ao preparo intestinal inadequado foi de 0% no GI, enquanto que o GC obteve uma taxa de 17,6%. Além disso, a taxa de biópsia foi maior no grupo de intervenção (28% vs. 13,3%, p=0,002). Conclusão: a educação do paciente aprimorada e realizada por enfermeiros aumenta as taxas de preparo intestinal adequado e, consequentemente, as taxas de intubação cecal. Para alcançar os padrões de qualidade de colonoscopia recomendados nas diretrizes, recomendamos que a educação do paciente inclua diferentes ferramentas de treinamento e seja realizada por profissionais da saúde.

Resumen Objetivo: evaluar el efecto de la educación perfeccionada realizada por enfermeros en la preparación intestinal adecuada y en las tasas de intubación cecal. Método: estudio prospectivo, casi experimental y comparativo, con abordaje cuantitativo. El grupo de intervención (n=150) recibió la educación perfeccionada y llamadas telefónicas recordatorias. El grupo de control (n=156) recibió las instrucciones estándar de la clínica por escrito. Las tasas de preparación intestinal adecuadas y otros indicadores de la calidad de la colonoscopia fueron comparadas entre los grupos. Resultados: las puntuaciones obtenidas en la Boston Bowel Preparation Scale y las tasas de preparación intestinal adecuadas fueron en el grupo de intervención mayores que en el grupo de control (6,76±2,1 vs. 5,56±2,4, p=0,000, y 80% vs. 69,2%, p=0,031, respectivamente). Las tasas de intubación cecal fueron mayores en el grupo de intervención (80% vs. 67,3%, p=0,012). La tasa de intubación cecal fracasada debido a la preparación intestinal inadecuada fue de 0% en el GI, en cuanto que el GC obtuvo una tasa de 17,6%. Además de eso, las tasas de biopsia fueron mayores en el grupo de intervención (28% vs. 13,3%, p=0,002). Conclusión: la educación del paciente perfeccionada y realizada por enfermeros aumenta las tasas de preparación intestinal adecuadas y, consecuentemente, las tasas de intubación cecal. Para alcanzar los estándares de calidad de colonoscopia recomendados en las directrices, recomendamos que la educación del paciente sea apoyada por diferentes herramientas de entrenamiento y realizada por profesionales de la salud.
