- Scientific TitlePreoperative optimization of pharmacotherapy in frail older patients with polypharmacy with the use of STRIP assistant: a clustered randomized trial.
- ACRONYMPROPOSE
- hypothesisIn frail older preoperative patients with polypharmacy, evaluation of medication, with the aid of the STRIP assistant, will identify potentially inappropriate medications and potentially prescribing omissions.
Optimization of pharmacotherapy will result in lower morbidity and mortality.
- Healt Condition(s) or Problem(s) studiedGeriatrics, Surgery

- Exclusion criteriaExclusie criteria: Patients under the age of 70 years. No polypharmacy. When information about the use of drugs was not available before the visit at the outpatient clinic.

- InterventionsThe intervention consists of a written pharmacotherapeutic advice, which will be generated by application of the STRIP assistant. The STRIP Assistant is an online software system (i.e. electronic version of the STRIP) developed to aid general practitioners and pharmacists to conduct a quick pharmacotherapeutic analysis.
Input for the STRIP assistant are the patient’s medication, medical history, vital signs and relevant laboratory results. The application of the STRIP assistant will be performed by an independent, clinically experienced resident, who is not involved in patient care at that moment. The written advice will be provided in a fixed format to the resident who performs the preoperative geriatric screening and will be used in the generation of the preoperative advice for the surgeon, including advice concerning medication.
- Primary outcomeThe primary outcome measure is the efficacy of the use of the STRIP assistant as a tool for polypharmacy optimization in addition to usual care in frail elderly patients in the clinical setting. The efficacy will be defined as the number of Potentially Inappropriate Medications (PIM’s) and Potentially Prescribing Omissions (PPO’s) identified per patient, compared to the ‘usual care’.
- Secondary outcomeThe number of missed, inadequate and potential deleterious advices will also be reported. Also, well-known ADRs, interactions and dose adjustments will be noted. Moreover, we want to investigate whether preoperative optimization of polypharmacy involving the STRIP assistant in older patients positively affects the postoperative morbidity, functionality and mortality 3 months and 1 year postoperatively when compared to the usual care.

To determine whether the intervention can define PIMs and PPOs, the preoperative medication will be independently reviewed on appropriateness (i.e. presence of PIM’s and PPO’s) by an expert panel in a selection of patients from both groups. This panel consists of at least a geriatrician/pharmacologist and a pharmacist/pharmacologist and will also evaluate the number of appropriate, indifferent or potential harmful decisions.
- TimepointsAt the visit for preoperative screening the PPO’s and PIM’s will be defined. At the day of surgery and three months postoperatively it will be checked whether the given advice concerning changes in medication is followed by the surgeon. Three months postoperatively also morbidity and functionality will be measured with a Mini Mental State Examination (MMSE), Geriatric Depression Scale (GDS), BMI, mobility and fall risk, vital signs, hand grip strength, the time needed to walk 4 meters and an electrocardiography Three months and one year after visiting mortality will be scored.

- Brief summaryA randomized controlled single center study in UMC Utrecht, The Netherlands.
Aim of the study is to investigate the effectiveness of STRIP assistant in the identification of potentially inappropriate medications and potentially prescribing omissions. Patients above 70 years with polypharmacy and scheduled for elective surgery will visit the outpatient clinic for pre-operative geriatric screening. A written pharmacotherapeutic advice, generated by application of the STRIP assistant, will be provided in a fixed format to the resident who performs the preoperative geriatric screening.
Primary outcome is the number of Potentially Inappropriate Medications (PIM’s) and Potentially Prescribing Omissions (PPO’s) identified per patient, compared to the ‘usual care’. Secondary outcome is the number of missed, inadequate and potential deleterious advices and mortality, morbidity and functionality 3 months and one year after surgery.
