Abstract: To mitigate flooding associated with the gas diffusion layer (GDL) during electroreduction of CO 2 , we report a hydrophobicity‐graded hydrophobic GDL (HGGDL). Coating uniformly dispersed polytetrafluoroethylene (PTFE) binders on the carbon fiber skeleton of a hydrophilic GDL uniformizes the hydrophobicity of the GDL and also alleviates the gas blockage of pore channels. Further adherence of the PTFE macroporous layer (PMPL) to one side of the hydrophobic carbon fiber skeleton was aided by sintering. The introduced PMPL shows an appropriate pore size and enhanced hydrophobicity. As a result, the HGGDL offers spatial control of the hydrophobicity and hence water and gas transport over the GDL. Using a nickel‐single‐atom catalyst, the resulting HGGDL electrode provided a CO faradaic efficiency of over 83 % at a constant current density of 75 mA cm −2 for 103 h operation in a membrane electrode assembly, which is more than 16 times that achieved with a commercial GDL.

Abstract: Pharmacists’ roles are expanding to delivering a wider set of professional services including medication management optimisation, vaccinations and screening services. Robust research determining whether pharmacists have the capacity to offer such services in the Australian community pharmacy setting is lacking. This protocol details a mixed methods study that investigates the variation in pharmacists’ daily tasks and the workspace they work in as a measure of their workload capacity for expanding pharmacy services. An observational time and motion study will be conducted in up to twenty community pharmacies in metropolitan and rural regions of Australia. A trained observer will follow a pharmacist and record the type, location and duration of tasks undertaken over the course of their working day. Data will be collected and analysed using the electronic Work Observation Method By Activity Timing (WOMBAT) tool. Pharmacists’ work patterns will be described as time for each task, and by proportionating multitasking and interruptions. This information will be combined with workspace data collected using floor plans, photographs and a qualitative assessment of the working environment completed by the observer. Analysis will include heat-mapped floor plans visually highlighting pharmacist movements. Pharmacists may provide solutions to the strained health workforce and system. There is limited quantitative evidence on whether pharmacists have the time or work setting to support such needs. The use of time and motion methodology is novel to Australian community pharmacy research, and the findings will provide a better understanding of pharmacists’ capacity and work environment.

Abstract: Objective: To determine the impact of the introduction of new pre-written orders for antimicrobials in a computerized provider order entry (CPOE) system on 1) accuracy of documented indications for antimicrobials in the CPOE system, 2) appropriateness of antimicrobial prescribing, and 3) compliance with the hospital’s antimicrobial policy. Prescriber opinions of the new decision support were also explored to determine why the redesign was effective or ineffective in altering prescribing practices. Methods: The study comprised two parts: a controlled pre-post study and qualitative interviews. The intervention involved the redesign of pre-written orders for half the antimicrobials so that approved indications were incorporated into pre-written orders. 555 antimicrobials prescribed before (September – October, 2013) and 534 antimicrobials prescribed after (March – April, 2015) the intervention on all general wards of a hospital were audited by study pharmacists. Eleven prescribers participated in semi-structured interviews. Results: Redesign of computerized decision support did not result in more appropriate or compliant antimicrobial prescribing, nor did it improve accuracy of indication documentation in the CPOE system (Intervention antimicrobials: appropriateness 49% vs. 50% compliance 44% vs. 42% accuracy 58% vs. 38% all p .05). Via our interviews with prescribers we identified five main reasons for this, primarily that indications entered into the CPOE system were not monitored or followed-up, and that the antimicrobial approval process did not align well with prescriber workflow. Conclusion: Redesign of pre-written orders to incorporate appropriate indications did not improve antimicrobial prescribing. Workarounds are likely when compliance with hospital policy creates additional work for prescribers or when system usability is poor. Implementation of IT, in the absence of support or follow-up, is unlikely to achieve all anticipated benefits.

Abstract: The uptake of the Personally Controlled Electronic Health Record (PCEHR) has been slowly building momentum in Australia. The purpose of the PCEHR is to collect clinically important information from multiple healthcare providers to provide a secure electronic record to patients and their authorised healthcare providers that will ultimately enhance the efficiency and effectiveness of healthcare delivery. Reasons for the slow uptake of the PCEHR and future directions to improve its usefulness is discussed later.

Abstract: Objective: To examine the evidence regarding the effectiveness of medication reconciliation and review and to improve clinical outcomes in hospitals, the community, and aged care facilities. Data Source: This systematic review was undertaken in concordance with the PRISMA statement. Electronic databases, including MEDLINE, PsycINFO, EMBASE, and CINAHL were searched for relevant articles published between January 2000 and March 2014. Study Selection and Data Extraction: Randomized and nonrandomized studies rating the severity of medication discrepancies and medication-related problems identified during medication reconciliation and/or review were considered for inclusion. Data were extracted independently by 2 authors using a data collection form. Data Synthesis: Of the 5292 articles identified, 83 articles met the inclusion criteria. Medication reconciliation identified unintentional medication discrepancies in 3.4% to 98.2% of patients. There is limited evidence of the potential of these discrepancies to cause harm. Medication reviews identified medication-related problems or possible adverse drug reactions in 17.2% to 94.0% of patients. The studies reported conflicting findings regarding the impact of medication review on length of stays, readmissions, and mortality. Conclusions: The evidence demonstrates that medication reconciliation has the potential to identify many medication discrepancies and reduce potential harm, but the impact on clinical outcomes is less clear. Similarly, medication review can detect medication-related problems in many patients, but evidence of clinical impact is scant. Overall, there is limited evidence that medication reconciliation and medication review processes, as currently performed, significantly improve clinical outcomes, such as reductions in hospital readmissions.
