Factors affecting antidepressant use by patients requiring Home Parenteral Nutrition.

BACKGROUND & AIMS Home parenteral nutrition (HPN) is a life-saving therapy for patients with chronic intestinal failure but can be associated with a degree of psychological distress. The factors associated with the need for antidepressants (AD) in this cohort have not yet been described. METHODS The study involved prospective data collection from patients attending HPN clinic at a national intestinal failure referral centre. Patients requiring HPN as a result of active malignancy were excluded. Patients were divided in two groups according to AD usage; demographic, anthropometric, socioeconomic characteristics and IVS regimens were compared between groups. RESULTS A total of 184 patients were recruited between July 2018 and April 2019, with an overall prevalence of AD use of 41.7%. Daily mean IVS volume was significantly higher among patients taking AD ('AD' group; 2125.48±991.8 ml/day, 'no-AD' group; 1828.54±847.0 ml/day, P = 0.039) with the proportion of patients needing high volume IVS (≥3000ml/day) being three-times higher in the AD group (20.0% vs. 6.1%, P = 0.006). The average energy IVS infusion per day was similar between the two groups. Hypnotic use (25.7% vs. 5.1%, P<0.001) and active smoking (32.3% vs. 14.1%, P = 0.006) were both significantly higher among the AD group. CONCLUSION This is the first study to demonstrate that AD use correlates with higher IVS volume rather than energy requirements in HPN patients, suggesting that high IVS volume requirements may be better associated with the patient's disease burden. Early and tailored mental health intervention may be beneficial in those with high IVS volume requirements. This article is protected by copyright. All rights reserved.
