BACKGROUND

The first Multi-center Medication Reconciliation Quality Improvement Study (MARQUIS1) demonstrated that implementation of a medication reconciliation best practices toolkit decreased total unintentional medication discrepancies in five hospitals. We sought to implement the MARQUIS toolkit in more diverse hospitals, incorporating lessons learned from MARQUIS1.

METHODS

MARQUIS2 is a pragmatic, mentored implementation QI study which collected clinical and implementation outcomes. Sites implemented a revised toolkit, which included interventions from these domains: 1) best possible medication history (BPMH)-taking; 2) discharge medication reconciliation and patient/caregiver counseling; 3) identifying and defining clinician roles and responsibilities; 4) risk stratification; 5) health information technology improvements; 6) improved access to medication sources; 7) identification and correction of real-time discrepancies; and, 8) stakeholder engagement. Eight hospitalists mentored the sites via one site visit and monthly phone calls over the 18-month intervention period. Each site's local QI team assessed opportunities to improve, implemented at least one of the 17 toolkit components, and accessed a variety of resources (e.g. implementation manual, webinars, and workshops). Outcomes to be assessed will include unintentional medication discrepancies per patient.

DISCUSSION

A mentored multi-center medication reconciliation QI initiative using a best practices toolkit was successfully implemented across 18 medical centers. The 18 participating sites varied in size, teaching status, location, and electronic health record (EHR) platform. We introduce barriers to implementation and lessons learned from MARQUIS1, such as the importance of utilizing dedicated, trained medication history takers, simple EHR solutions, clarifying roles and responsibilities, and the input of patients and families when improving medication reconciliation.

PURPOSE OF REVIEW

To describe the mechanisms and clinical relevance of emergent resistance to three recently introduced beta-lactamase inhibitor combinations (BLICs) active against resistant Gram-negative organisms: ceftolozane-tazobactam, ceftazidime-avibactam, and meropenem-vaborbactam.

RECENT FINDINGS

Despite their recent introduction into practice, clinical reports of resistance to BLICs among typically susceptible organisms have already emerged, in some cases associated with therapeutic failure. The resistance mechanisms vary by agent, including mutations in beta-lactamase active sites, upregulation of efflux pumps, and alterations in the structure or expression of porin channels. These changes may confer cross-resistance or, rarely, increased susceptibility to related agents. Clinicians need to be aware of the potential for initial or emergent resistance to BLICs and ensure appropriate antimicrobial susceptibility testing is performed. Dose optimization and novel combinations of agents may play a role in preventing and managing resistance. Recently approved BLICs have provided important new therapeutic options against resistant Gram-negative organisms, but are already coming up against emergent resistance. Awareness of the potential for resistance, early detection, and dose optimization may be important in preserving the utility of these agents.

Many neurologic diseases disproportionately affect women, particularly during their reproductive years. For many of these diseases, monoclonal antibodies (mAbs) are becoming widely available as a treatment option, for example, in migraine, multiple sclerosis, and myasthenia gravis. Yet, despite how common pregnancy is (latest estimates suggest that 86% of US women ages 40-44 have given birth), there is a paucity of research on the safety of prescription medications, including mAbs, during the peripartum period. In this article, we focus on the safety of mAbs during breastfeeding. We summarize how pregnancy affects the trajectory of these diseases and explore the benefit derived from mAb therapies. We posit that as neurologists, we are uniquely poised to lead the study of peripartum safety for the mAbs now on the market and provide a framework for their future study.

Rates of positive margins after surgical resection of invasive lobular carcinoma (ILC) are high (ranging from 18 to 60%), yet the efficacy of re-excision lumpReceptor subtypeectomy for clearing positive margins is unknown. Concerns about the diffuse nature of ILC may drive increased rates of completion mastectomy to treat positive margins, thus lowering breast conservation rates. We therefore determined the success rate of re-excision lumpectomy in women with ILC and positive margins after surgical resection. We identified 314 cases of stage I-III ILC treated with breast conserving surgery (BCS) at the University of California, San Francisco. Surgical procedures, pathology reports, and outcomes were analyzed using univariate and multivariate statistics and Cox-proportional hazards models. We evaluated outcomes before and after the year 2014, when new margin management consensus guidelines were published. Positive initial margins occurred in 118 (37.6%) cases. Of these, 62 (52.5%) underwent re-excision lumpectomy, which cleared the margin in 74.2%. On multivariate analysis, node negativity was significantly associated with successful re-excision (odds ratio [OR] 3.99, 95% CI 1.15-13.81,  = 0.029). After 2014, we saw fewer initial positive margins (42.7% versus 25.5%,  = 0.009), second surgeries (54.6% versus 20.2%,   0.001), and completion mastectomies (27.7% versus 4.5%,   0.001). In this large cohort of women with ILC, re-excision lumpectomy was highly successful at clearing positive margins. Additionally, positive margins and completion mastectomy rates significantly decreased over time. These findings highlight improvements in management of ILC, and suggest that completion mastectomy may not be required for those with positive margins after initial BCS.

BACKGROUND

Diversifying the medical student body without striving for equity in the clerkship (first full-time clinical training year) learning environment disadvantages under-represented in medicine (UIM) students and undermines the educational process.

CONTEXT

To characterise and address inequities within an internal medicine clerkship, we conducted a multi-phased process to promote equity in the clerkship learning environment at an urban medical school with multiple sites. … we conducted a multi-phased process to promote equity in the clerkship learning environment … INNOVATION: The process to improve the learning environment and equity in the clerkship included: (i) a literature review and needs assessment (focus group) with UIM students; (ii) a medicine clerkship retreat with school leaders and diversity experts to reflect on the needs assessment data and generate interventions to improve equity; (iii) a member checking session with UIM students to ensure that the proposed solutions addressed the inequities that were noted in the needs assessment.

IMPLICATIONS

The needs assessment revealed eight themes in the clerkship learning environment that were mapped to a published framework describing barriers encountered by UIM students. These themes informed the development of five clerkship pilot interventions. Implementing interventions inspired by UIM student perspectives may improve the learning environment in clinical clerkships by encouraging a culture of equity. The three-phased approach described here provides leaders who direct educational programmes with a framework to initiate change by characterising inequities as a springboard for developing solutions.
