Audit of parenteral nutrition use in Guernsey.
OBJECTIVE
This audit was precipitated by a huge increase in the local prescribing of parenteral nutrition (PN) in Guernsey and concomitant burden on pharmacy/sterile services unit staff. It aimed to establish whether PN was being used appropriately and the extent to which feeding prescriptions followed U.K. National Institute for Health and Clinical Excellence and local Guernsey guidelines with regard to the initiation, monitoring and cessation of feeding.


METHODS
All PN patients at the Princess Elizabeth Hospital in Guernsey during a 1 year period (November 2006-December 2007) were subject to audit. A data-collection form was designed to ascertain exclusion of other feeding options, risk of re-feeding complications, suitability of PN regime, compliance with monitoring guidelines and patient outcomes. Copies of the form were completed by pharmacists/dietitians.


RESULTS
Eighteen men and 12 women were included (average age 67 years). PN was initiated appropriately, with the most common indication being gastrointestinal surgery. Assessment of re-feeding risk and use of low-calorie starter regimes with full micronutrient and electrolyte additions was routinely carried out, except in the case of two patients admitted at weekends. Five patients were not given appropriate supplementary intravenous Pabrinex. The duration of PN ranged from 2 to 62 days (average 14 days). The majority of patients were fed continuously but three longer-term PN patients were fed cyclically (12-16 h). Only 13 patients had accurate daily fluid-balance charts kept. Seventeen had a planned cessation of PN, of whom only 11 were weaned off appropriately. Two patients were re-admitted for feeding problems within 28 days of discharge.


CONCLUSIONS
The audit findings demonstrated that PN at the Princess Elizabeth Hospital was generally being initiated, monitored and stopped with a high level of consideration to local guidelines. The main problem identified was with PN started at or immediately prior to the weekend when appropriate assessment and initiation could not be guaranteed.
