Abstract Background Number of drugs are increasing with older age and present a risk factor for various adverse health outcomes. A comprehensive medication therapy management (MTM) before admission for elective surgery may help reduce unnecessary and potentially inadequate medications (PIM) and thus improve patient health. Our goal was to evaluate the implementation of PHAROS, a perioperative MTM intervention study, from the perspective of health care providers. The PHAROS intervention aimed to improve medication appropriateness in older inpatients at the outpatient / inpatient interface. Methods We performed a qualitative interview study within a pilot intervention study comparing a comprehensive MTM with standard care in older inpatients (≥ 65 years) in Germany. Semi-structured interviews with health care professionals were performed from March to July 2021. The Consolidated Framework for Implementation Research (CFIR) was used to guide development of interview guide, data coding, analysis, and reporting of findings. Results Ten health care professionals involved in the implementation of PHAROS were interviewed. Based on CFIR-constructs, facilitators included need for and meaningfulness of the intervention as well as positive and supportive cooperation within the project team. Implementation of MTM at the interface of inpatient to outpatient care before elective surgery was hampered by personal and organizational barriers as well as barriers resulting from broader health care structures in Germany. In particular, lack of documentation standards, missing compatibility with clinical workflow, difficulties in stakeholder engagement, as well as communication barriers between outpatient and inpatient care interfaces hindered implementation of the intervention. Conclusions Further studies should consider focusing on facilitators to pharmaceutical implementations such as transparent and clear communication structures between stakeholders, standardization of medication documentation, and intervention structures that are adapted to hospital workflows.

Background: It remains unknown whether there is a causal relationship between intraoperative hypotension and postoperative neurocognitive disorders. We tested the hypothesis that personalised—compared to routine—intraoperative blood pressure management reduces the incidence of postoperative neurocognitive disorders in patients having major noncardiac surgery. Methods: In this single-centre trial, 328 elective major noncardiac surgery patients were randomly allocated to receive personalised blood pressure management (i.e. maintaining intraoperative mean arterial pressure [MAP] above preoperative baseline MAP from automated 24-h blood pressure monitoring) or routine blood pressure management (i.e. maintaining MAP above 65 mm Hg). The primary outcome was the incidence of neurocognitive disorders (composite of delayed neurocognitive recovery and delirium) between postoperative days 3 and 7. Results: The primary outcome, neurocognitive disorders, occurred in 18 of 147 patients (12%) assigned to personalised and 21 of 148 patients (14%) assigned to routine blood pressure management (odds ratio [OR]=0.84, 95% confidence interval [CI]: 0.40–1.75, P=0.622). Delayed neurocognitive recovery occurred in 17 of 146 patients (12%) assigned to personalised and 17 of 145 patients (12%) assigned to routine blood pressure management (OR=0.99, 95% CI: 0.45–2.17, P=0.983). Delirium occurred in 2 of 157 patients (1%) assigned to personalised and 4 of 158 patients (3%) assigned to routine blood pressure management (OR=0.50, 95% CI: 0.04–3.53, P=0.684). Conclusions: Personalised intraoperative blood pressure management maintaining preoperative baseline MAP neither reduced the incidence of the composite primary outcome neurocognitive disorders between postoperative days 3 and 7 nor the incidences of the components of the composite primary outcome—delayed neurocognitive recovery and delirium—compared to routine blood pressure management in patients having major noncardiac surgery.
