In today's complex healthcare landscape, exacerbated by resource constraints at various levels, optimization of health professionals' roles is becoming increasingly paramount. Interprofessional collaboration, underpinned by role recognition and teamwork, leads to improved patient and organizational outcomes. Hospital pharmacists play a pivotal role in multidisciplinary teams, and it is imperative to understand multidisciplinary viewpoints on hospital pharmacists' roles to guide role prioritization and organizational efficiency. However, no study extensively investigated multidisciplinary views on values of diverse pharmacist roles in tertiary settings. This study aims to address this gap by examining non-pharmacist health professionals' views on hospital pharmacists' roles, recognizing their specialized niches as a crucial step towards optimizing their roles and services in Australia and internationally. Multiple focus group discussions and interviews were held via a virtual conferencing platform. Study participants were recruited using the study investigators' professional networks who were non-pharmacist health professionals with experience working with pharmacists in hospital settings. Data were collected from transcripts of the focus group recordings, which were later summarized using descriptive statistics and thematic analysis. Overarching themes were categorized and mapped against work system models to conceptualize organizational implications of multidisciplinary feedback, linking them to patient and organizational outcomes. Twenty-seven health professionals participated across focus groups and interviews, with the majority of professions being doctors and nurses. Three major themes were identified as follows: (i) overarching perceptions regarding hospital pharmacists; (ii) professional niches of hospital pharmacists; and (iii) future opportunities to optimize hospital pharmacy services. Valued professional niches included patient and health professional educators, transition-of-care facilitators, and quality use of medicines analysts. The study highlights critical insights into hospital pharmacists' roles in Australia, identifying their niche expertise as vital to healthcare efficiency and success. Based on multidisciplinary feedback, the study advocates for strategic role optimization and targeted research for enhanced clinical, economic, and organizational outcomes., (© The Author(s) 2024.

The plasma membrane protects the interiors of cells from their surroundings and also plays a critical role in communication, sensing, and nutrient import. As a result, the cell membrane and its constituents are among the most important drug targets. Studying the cell membrane and the processes it facilitates is therefore crucial, but it is a highly complex environment that is difficult to access experimentally. Various model membrane systems have been developed to provide an environment in which membrane proteins can be studied in isolation. Among them, tethered bilayer lipid membranes (tBLMs) are a promising model system providing a solvent-free membrane environment which can be prepared by self-assembly, is resistant to mechanical disturbances and has a high electrical resistance. tBLMs are therefore uniquely suitable to study ion channels and charge transport processes. However, ion channels are often large, complex, multimeric structures and their function requires a particular lipid environment. In this paper, we show that SthK, a bacterial cyclic nucleotide gated (CNG) ion channel that is strongly dependent on the surrounding lipid composition, functions normally when embedded into a sparsely tethered lipid bilayer. As SthK has been very well characterized in terms of structure and function, it is well-suited to demonstrate the utility of tethered membrane systems. A model membrane system suitable for studying CNG ion channels would be useful, as this type of ion channel performs a wide range of physiological functions in bacteria, plants, and mammals and is therefore of fundamental scientific interest as well as being highly relevant to medicine.

Background: Pharmacists have become increasingly integrated within the interprofessional hospital team as their scope of practice expanded in recent decades. However, limited research has explored how the roles of hospital pharmacists are perceived by other health professionals., Aim/objectives: To identify what is known about the perceptions of hospital pharmacists' roles and hospital pharmacy services held by non-pharmacist health professionals., Methods: A systematic literature search was conducted in August 2022 in MEDLINE, Embase, and CINAHL to identify peer-reviewed articles published between 2011 and 2022. Title/abstract and full-text screening, by two independent reviewers, identified eligible articles. Inclusion criteria included qualitative studies in hospital settings that reported perceptions regarding the roles of hospital pharmacists held by non-pharmacist health professionals. Data were extracted using a standardised extraction tool. Collated qualitative data underwent inductive thematic analysis by two independent investigators to identify codes, which were reconciled and merged into over-arching themes through a consensus process. Findings were assessed to measure confidence using the GRADE-CERQual criteria., Results: The search resulted in 14,718 hits. After removing duplicates, 10,551 studies underwent title/abstract screening. Of these, 515 underwent full-text review, and 36 were included for analysis. Most studies included perceptions held by medical or nursing staff. Hospital pharmacists were perceived as valuable, competent and supportive. At an organisational level, the roles of hospital pharmacists were perceived to benefit hospital workflow and improve patient safety. Roles contributing to all four domains of the World Health Organization's Strategic Framework of the Global Patient Safety Challenge were recognised. Highly-valued roles include medication reviews, provision of drug information, and education for health professionals., Conclusion: This review describes the roles hospital pharmacists performed within the interprofessional team, as reported by non-pharmacist health professionals internationally. Multidisciplinary perceptions and expectations of these roles may guide the prioritisation and optimisation of hospital pharmacy services., Competing Interests: The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: Kyung Min Kirsten Lee reports financial support was provided by Australian Government Department of Education. Sangseo Kim reports financial support was provided by Australian Government Department of Education. Ivanka Koeper reports a relationship with SA Health that includes: employment. Isabella Singh reports a relationship with Northern Territory Department of Health that includes: employment. Jacinta Johnson reports a relationship with SA Health that includes: employment.

Background: Deprescribing may benefit older frail patients experiencing polypharmacy. We investigated the scope for deprescribing in acutely hospitalised patients and the long-term implications of continuation of medications that could potentially be deprescribed., Methods: Acutely hospitalised patients (n = 170) discharged to Residential Aged Care Facilities, ≥75 years and receiving ≥5 regular medications were assessed during admission to determine eligibility for deprescribing of key drug classes, along with the actual incidence of deprescribing. The impact of continuation of nominated drug classes (anticoagulants, antidiabetics, antiplatelets, antipsychotics, benzodiazepines, proton pump inhibitors (PPIs), statins) on a combined endpoint (death/readmission) was determined., Results: Hyperpolypharmacy (>10 regular medications) was common (49.4%) at admission. Varying rates of deprescribing occurred during hospitalisation for the nominated drug classes (8-53%), with considerable potential for further deprescribing (34-90%). PPI use was prevalent (56%) and 89.5% of these had no clear indication. Of the drug classes studied, only continued PPI use at discharge was associated with increased mortality/readmission at 1 year (hazard ratio 1.54, 95% confidence interval (1.06-2.26), P = 0.025), driven largely by readmission., Conclusion: There is considerable scope for acute hospitalisation to act as a triage point for deprescribing in older patients. PPIs in particular appeared overprescribed in this susceptible patient group, and this was associated with earlier readmission. Polypharmacy in older hospitalised patients should be targeted for possible deprescribing during hospitalisation, especially PPIs., (© The Author(s) 2021.
