BACKGROUND: Vitamin B12 (VB12) deficiency is a well-described complication post-gastrectomy. It is caused by the loss of parietal cell mass leading to megaloblastic anaemia. This closed-loop audit assesses patient understanding of and adherence with VB12 supplementation guidelines post-gastrectomy.
METHODS: A closed-loop audit cycle was performed. After the first cycle, an educational intervention was actioned prior to re-audit. One hundred twenty-five patients who underwent gastrectomy between 2010 and 2020 were available for study (86 total gastrectomies (TG), 39 subtotal gastrectomies (STG)). Twenty-nine patients who had not been adherent with VB12 supplementation/surveillance were eligible for re-audit.
RESULTS: 91.9% (79/86) of TG patients reported adherence in regular parenteral VB12 supplementation. Adherence was significantly lower for STG for checking (and/or replacing) their VB12, with only 53.8% (21/39) checking their VB12 levels. 67/125 (53.6%) of the patients stated that they knew it was important to supplement B12 post-gastrectomy. 37.8% (43/113) of participants could explain why this was important, and 14.4% (18/125) had any knowledge of the complications of VB12 deficiency. Following re-audit, 5/8 (57.5%) of TG patients who had not been adherent with VB12 supplementation in the first cycle were now adherent with VB12 supplementation following our educational intervention. 7/17 (41.2%) of the STG group had received VB12 or made arrangements to receive supplemental VB12 if it was indicated.
CONCLUSION: This study demonstrates good adherence in those undergoing TG. Patient understanding correlates with adherence, suggesting that patient education and knowledge reinforcement may be key to adherence with VB12 supplementation. A simple educational intervention can improve adherence with VB12 supplementation in patients undergoing gastrectomy.
