Summary

Primary Objective: To quantify the benefits of the SENATOR decision support software on the reduction of ADR rates in older hospitalized patients. Secondary Objectives: To evaluate the effect of SENATOR with regard to use of appropriate non-pharmacological therapies in subjects with one core geriatric syndrome. Tertiary Objectives: to examine the association of SENATOR use with subject survival, morbidity and health related quality of life. Health Economic Objective: To examine the potential health economic consequences of using SENATOR. There are two study phases: Phase I: Prospective multinational, multicentre observational study to estimate the baseline adjudicated medical and surgical ADR rates by clinical subspeciality in 6 international sites. Phase II: Prospective multinational, multicentre, block randomized, two parallel arm, open label, controlled trial, with blinded outcome ascertainment, of the efficacy of SENATOR software in reducing ADRs in older hospitalized subjects.

Detailed description

Phase I is designed to test the electronic case report form (eCRF) and the ADR ascertainment method in the six clinical sites in advance of Phase II (randomization phase). In Phase I, we recruited 644 older multi-morbid patients from the 6 clinical sites. After obtaining written informed consent, patients' demographic, clinical and medication details were entered to the eCRF. In the event of one a 12 item Trigger List of adverse clinical events occurring, the eCRF automatically generated a Trigger List assessment proforma. The 12 items in the Trigger List included: 1. New onset falls 2. New onset unsteady gait 3. Acute kidney injury 4. Symptomatic orthostatic hypotension 5. Serum electrolyte disturbance 6. Symptomatic bradycardia 7. New onset major constipation 8. Acute bleeding 9. Acute dyspepsia/nausea/vomiting 10. Acute diarrhea 11. Delirium 12. Symptomatic hypoglycemia In addition, we have included 'Unspecified adverse event' in order to capture the wide range of well recognized ADRs associated with various medications. For example, the rapid onset of a generalized maculopapular rash in a patient with penicillin hypersensitivity would be identified as an ADR under the 'Unspecified adverse event' category. ADR adjudication in Phase I was blinded and no ADR adjudications were undertaken by the site principal investigator (PI). ADRs were defined as 'definite', probable', 'possible', 'unlikely' or 'indeterminate' according to WHO-UMC ADR causality critria. ADR severity was defined according to a modified Hartwig ADR severity scale ranging from Level 1 (trivial) to Level 7 (fatal). Consensus on ADR causality was achieved through a potential endpoint adjudication committee (PEPAC), whose members were the 6 clinical site PI's. A matrix for achieving consensus was devised, such that there was a final decision on the causality of all potential ADRs.
