Hospital Physicians' Influence on Gastrointestinal Protection during Treatment with Non-Steroidal Anti-Inflammatory Drugs and Acetylsalicylic Acid and the Impact on Prescribing in Primary Care

Background

The aim of this study was to describe the use of gastrointestinal (GI) protection before, during and after hospitalisation for elderly patients using NSAID or low-dose ASA.

Methods

This study included all elderly patients (75+) admitted to hospital in the period of 1^st April 2010 to 31^st March 2011 at Odense University Hospital, Denmark, who were regular users of NSAID or low-dose ASA before hospital admission, or had one of these drugs initiated during hospital stay. By using pharmacy dispensing data and a hospital-based pharmacoepidemiological database, the treatment strategy for the individual patients was followed across hospital stay.

Results

In total, 3,587 patients were included. Before hospital admission, 93 of 245 NSAID users (38.0%) and 597 of 1994 user of low-dose ASA (29.9%) had used GI protection. During hospital stay, use of GI protection increased to 75% and 33.9%, respectively. When hospital physicians initiated new treatment with NSAID or with low-dose ASA, 305 of 555 (55.0%) and 647 of 961 (67.3%) were initiated without concomitant use of GI protection. When hospital physicians initiated GI protection, 26.8–51.0% were continued in primary care after discharge.

Conclusions

During hospital stay, the use of GI protection increases, but when new treatment with NSAIDs or low-dose ASA is initiated in hospital, the use of gastrointestinal protection is low. The low use of GI protection is carried on in primary care after discharge.
