193 Audit on Inappropriate Prescribing of Proton Pump Inhibitors Amongst Patients over 65 Years in an Acute Rehabilitation Hospital (Age and Ageing)

AbstractBackgroundProton pump inhibitors (PPIs) are one of the most frequently prescribed drug classes in the older person. Indications for PPI use are outlined in the NICE guidelines, however they are often prescribed without an appropriate indication resulting in increased healthcare costs and increased exposure to potential adverse clinical effects.MethodsTo determine the rate of inappropriate prescribing of PPI`s, an audit was carried out to assess the incidence of inappropriate prescribing in an Acute Rehabilitation facility pre and post Education to Hospital Doctors. An audit was carried out, pre and post intervention, on patients over the age of 65 years admitted to an acute rehabilitation hospital between 2018 and 2019. Patient`s medical charts were reviewed and data was collected on PPI prescribing.ResultsCycle 1-Pre Education; 83 people included in the audit. Mean age was 80.8 years[SD ±9]. 43% of patients were on a PPI, all of which were prescribed the generic form. 83.4% of patients had no indication for PPI use. Of the 16.6%, indications included GORD, Barrett`s oesophagus, PUD and PPI prophylaxis against NSAID`s including aspirin. 77.7% were on therapeutic dose without any indication. 100% of patients were on PPI for longer than 6 weeks.Cycle 2, Post education: 86 patients were included in re-audit. Mean age was 81.5[SD ±10]. 60.4% of patients were on PPI. Of those, 55% had no indication for PPI. Of the 44% on PPI, indications were similar to those in Cycle 1. 83% of patients were on PPI longer than 6 weeks. 56.5% were on inappropriate dose of PPI.ConclusionThis audit highlighted the inappropriate prescribing of PPI`s in the older person. By providing education to Doctors about NICE PPI prescribing guidelines, overall rate of inappropriate prescribing of PPI decreased by 28.4% and accurate dosing of PPI improved by 21.2%.
