Legert, K.G., Remberger, M., Ringden, O., Heimdahl, A., & Dahllof, G. (2014). Reduced intensity conditioning and oral care measures prevent oral mucositis and reduces days of hospitalization in allogeneic stem cell transplantation recipients. Supportive Care in Cancer, 22, 2133–2140.
To compare the incidence of oral mucositis (OM) in patients conditioned with myloablative conditioning (MAC) versus reduced-intensity conditioning (RIC) and to determine the effect of a new oral care protocol
A radiographic full-mouth exam and an oral exam by an investigating dentist were performed one week prior to hematopoietic stem cell transplantation (HSCT). Prior to the start of conditioning, daily oral exams began three days prior to HSCT for 25 days or until discharge. A dentist or dental hygienist assessed oral cavities three times per week. From 2007 to 2010, 142 patients used a protocol (soft tooth brushing twice daily only; no interdental brushes, toothpicks, or flossing were allowed). From 2010 to 2011, 29 patients received the intensive protocol (intensive protocol brushing, interdental brushes or flossing, sucking on ice chips every two to three hours while awake, rinsing normal saline solution every two hours while awake from transplantation until neutrophil count was > 0.5). Dental infections foci were treated conservatively.
Quasi-experimental
Patients treated with the oral protocol in 2011 had significantly lower OM scores than those treated with the previous protocol (p = 0.013).
MAC conditioning was correlated with significantly higher OM scores (p < 0.001). Lower OM scores were associated with the intensive oral protocol intervention. Patients treated in later years (2011) demonstrated a decrease in OM scores, which were caused by an increased use of RIC and improved standards of oral care.
Oral mucositis is a side effect of the conditioning regimens for HSCT. This study revealed that with consistent assessment, support, and a more intensive oral care protocol using ice and normal saline rinses, there is a potential to reduce the severity of this side effect. More nursing research is needed in this area.
