[The proper use of oral nutritional supplements in a French Ehpad]

Undernutrition in residents of residential care facilities for the dependent elderly can be managed by oral nutritional supplements (ONS). The objective of this study is to evaluate their proper use. A total of 41.9% of residents on NOCs were malnourished on the day of the audit, compared with 71.5% before the introduction of NOCs. NOCs were administered according to the dietician's prescription, which differed from the doctor's prescription in more than half of the cases. NOCs were fully consumed by 79.2% of residents.

Olfactory Dysfunction Predicts Frailty and Poor Postoperative Outcome in Older Patients Scheduled for Elective Non-Cardiac Surgery

OBJECTIVES

Frailty has been suggested to take part in the recently demonstrated link between olfactory dysfunction and overall mortality risk. Preoperative assessment of frailty is essential to detect the most vulnerable patients scheduled for surgery. The aim of this study was to evaluate whether olfactory dysfunction is a reliable predictor of preoperative frailty and postoperative outcome.

DESIGN

This was a single-center prospective observational study conducted between July and October 2020 in Brussels, Belgium.

SETTING AND PARTICIPANTS

155 preoperative patients aged from 65 years old and scheduled for elective non-cardiac surgery.

MEASUREMENTS

Olfactory function was examined using the Sniffin' Sticks 12-item identification test. Frailty was assessed using the Edmonton Frail Scale (EFS) and handgrip strength. The clock drawing test (CDT) from the EFS was also analyzed separately to evaluate cognitive function. Patients were followed for postoperative complications and mortality over one year.

RESULTS

Olfactory dysfunction was significantly associated with the EFS score, anosmic patients having a higher median EFS score than normosmic patients (6[4-7] vs 4[2-5], p = .025). Anosmic patients had an increased odds of being frail after adjusting for possible confounding factors (OR: 6.19, 95% CI: 1.65-23.20, p = .007) and were more at risk of poor postoperative outcome (including complications and death) (OR: 4.33, 95% CI: 1.28-14.67, p = .018).

CONCLUSIONS

Olfactory dysfunction is associated with preoperative frailty determined by the EFS and with poor post-surgical outcome at one-year.
