Percutaneous endoscopic gastrostomy: a prospective audit of the impact of guidelines in two district general hospitals in the United Kingdom.

OBJECTIVE

Percutaneous endoscopic gastrostomy (PEG) is the accepted method for long-term enteral nutrition. Recent studies have suggested a higher mortality than was initially reported. The demands for gastrostomy insertion have risen, encompassing indications where the long-term outcomes are uncertain. We, therefore, constructed guidelines to try and improve the appropriateness of patient selection. Our aim was to prospectively assess the impact of guidelines for PEG insertion over a 1-yr period in a single center, Rotherham District General Hospital (hospital A) and compare against an adjacent center serving a similar population, Doncaster Royal Infirmary (hospital B) where guidelines had not been instituted.

METHODS

Data were collected from June, 1998 to May, 1999. Indication for PEG was documented and survival analysis performed using the Kaplan-Meier survival method.

RESULTS

The number of PEG insertions had been rising each year in both centers. After guidelines were introduced in hospital A, the number of procedures fell by 20, whereas in hospital B, the PEG insertion rate continued to rise (p = 0.02). There was a lower mortality observed in hospital A (at 1 month, 16%; at 3 months, 26%; at 6 months, 39%; and at 1 yr, 46%) than in hospital B (at 1 month, 26%; at 3 months, 44%; at 6 months, 58%; and at I yr, 68%), although this did not achieve statistical significance (log rank test, p = 0.1).

CONCLUSIONS

This is the first study to prospectively assess the impact of guidelines and a proactive role in the decision for PEG insertion. Fewer procedures were performed, and there was a trend toward a reduction in mortality.
