简要总结
The objective of this randomized controlled trial (RCT) is to evaluate whether the Systematic Tool to Reduce Inappropriate Prescribing (STRIP), put into practice through the STRIP Assistant (STRIPA) and implemented by general practitioners (GPs), will lead to an improvement in clinical and economic outcomes in patients aged 65 or older with multimorbidity and polypharmacy.
详细描述
Background:
Policy makers face many challenges, when they plan health care systems to meet the needs of the fast growing elderly population. More than 60% of the elderly suffer from multiple chronic conditions (multimorbidity - commonly defined as ≥3 chronic diseases) and get multiple drugs (polypharmacy - commonly defined as ≥5 regular medications). Multimorbid patients are often excluded from randomized controlled trials (RCT) and consequently most prescribing guidelines address diseases in isolation. Consequently, there is inappropriate prescribing, which results in diminished health states and lower quality of life of the patients.
Older patients usually rely on their general practitioners (GPs) to manage their medications. However, GPs often have limited time to adapt polypharmacy. Reviewing medications and understanding their interactions based on a list of diagnoses and drugs is complex and time consuming. Furthermore, due to the increase of patients with multimorbidity and polypharmacy, medication review especially in patients with many drugs is often neglected. Pilot data from the Netherlands showed that a software-assisted method, called STRIPA, was effective for optimizing pharmacotherapy in primary care. Through the OPTICA trial this tool will now be tested in the Swiss primary care context.
Study design:
The OPTICA trial is a single-site cluster randomized controlled trial (RCT), which will be conducted at the Institute for Primary Health Care of the University of Bern (BIHAM). All study-related tasks will be performed centrally at the BIHAM except for patient recruitment and use of the STRIPA, as these two tasks will be performed in participating GP offices.

盲法说明
The OPTICA study is partially blinded, with blinding being implemented as follows:
- Due to the nature of the study intervention participating GPs (care providers) cannot be blinded.
- Patients remain blinded. They will not be informed to which treatment arm their GP is allocated to, in order to minimize performance and other reporting biases. Despite this, they receive a "high-level description" of the study question and the study procedures.
- Data collection for primary and secondary outcome analyses will be conducted by blinded study team members.
- Outcome adjudication (MAI and AOU assessment) will be performed by blinded study team members.

研究组 & 干预措施
STRIPA intervention
GPs in the intervention group will perform a STRIPA analysis for each of their 8-10 patients after the recruitment of the patient into the OPTICA trial, so that the results can be discussed in the next consultation and a shared decision-making can be performed.
STRIPA is a structured method to perform pharmacotherapy optimization. The STRIPA intervention in the OPTICA trial consists of 4 steps:
- recording medication and diagnoses in STRIPA (upload from data from the 'Family medicine ICPC Research using Electronic medical records' (FIRE) database)
- structured drug review through the GP based on the STRIPA with the integrated STOPP/START criteria
- shared decision-making between GP and patient with possible adaptation of the recommendation
- follow-up through study team
干预措施: STRIPA intervention (Device)
Sham intervention
Patients in the control group will receive a sham intervention, which consists of a usual medication review by their GP as well as a shared decision making of the latter.
干预措施: Sham intervention (Other)
结局指标
主要结局
Patients' medication appropriateness, as measured by two complementary co-primary outcomes: Co-primary outcome #1: change in the Medication Appropriateness Index (MAI)
时间窗: 12 months
Medication Appropriateness Index (MAI), assessed at baseline as well as at the 6 and 12 months follow-ups for each chronic medication of the patient. The 10 item version of the MAI will be used, but the cost-effectiveness item will be excluded. The MAI score for each medication will range from 0 to 17.
Patients' medication appropriateness, as measured by two complementary co-primary outcomes: Co-primary outcome #2: change in the Assessment of Underutilization (AOU)
时间窗: 12 months
Assessment of Underutilization (AOU), assessed for each of the patients' chronic conditions at baseline as well as at the 6 and 12 months follow-ups. For each chronic condition of the patient, the assessors decided whether there is i) no omission, ii) marginal omission, or iii) omission of indicated medication.
