The attitudes and experiences of patients with advanced malignancy receiving home enteral nutrition – a qualitative study

Psychosocial impacts of being nil-by-mouth as an adult: A scoping review

AIM

To map existing evidence and identify gaps in the literature concerning psychosocial impacts of being nil by mouth (NBM) as an adult.

DESIGN

A scoping review of the literature was undertaken using JBI guidance. A protocol was registered on the Open Science Framework (osf.io/43g9y). Reporting was guided by Preferred Reporting Items for Systematic Reviews and Meta-Analysis extension for Scoping Reviews (PRISMA-ScR).

METHODS

A comprehensive search of six databases (CINAHL, Embase, MEDLINE, PsycINFO, SCOPUS and Web of Science) was performed for studies published up to February 2023, with no restriction to study type. A scope of the grey literature was also undertaken. Two authors independently assessed eligibility and extracted data. Descriptive statistical analysis and narrative synthesis were used, and patient and public involvement included in funding discussions.

RESULTS

A total of 23 papers were included in the review, consisting of 14 primary studies (7 qualitative and 7 quantitative) and 9 grey literature. Both global psychological distress and distress specific to being NBM (thirst, missing food and drink) were reported. Caregivers also experience distress from their family member being NBM. Furthermore, social impacts were reported for both patient and caregiver, primarily social isolation and subsequent low mood.

CONCLUSION

Furthermore, research is needed to understand the prevalence of this population, how best to measure psychosocial impacts and to explore whether (and how) psychosocial impacts change over time. Advancement in this area would enable better service development to optimize care for this patient group. WHAT IS KNOWN ABOUT THIS TOPIC?: Eating and drinking provides more than nutrition and hydration. A wide range of conditions can lead to recommendations for no longer eating and drinking (nil by mouth). Being nil by mouth (NBM) for short periods such as pre-operative fasting causes distress; however, little is understood about impact on longer-term abstinence from eating and drinking. WHAT THIS PAPER ADDS?: Psychosocial consequences of being nil by mouth (NBM)have been investigated by both quantitative and qualitative studies. Being NBM impacts both patients and caregivers in various psychosocial aspects, including distress and social isolation. Several gaps remain, however, regarding ways to measure psychosocial impact of being NBM.
