Objectives: This article summarises all the available evidence on the impact of introducing blood-based point-of-care panel testing (POCT) in ambulatory care on patient outcomes and healthcare processes.
Design: Systematic review and meta-analysis of randomised-controlled trials and before-after studies.
Data Sources: Ovid Medline, Embase, Cochrane Database of Systematic Reviews, Cochrane CENTRAL, Database of Abstracts of Reviews and Effects, Science Citation Index from inception to 22 October 2019.
Eligibility Criteria For Selecting Studies: Included studies were based in ambulatory care and compared POCT with laboratory testing. The primary outcome was the time to decision regarding disposition that is, admission/referral termed disposition decision (DD) time. Secondary outcomes included length of stay (LOS) at the ambulatory care unit/practice and mortality.
Results: 19 562 patients from nine studies were included in the review, eight of these were randomised-controlled trials, and one was a before-after study. All the studies were based in either emergency departments or the ambulance service; no studies were from primary care settings. General panel tests performed at the POCT resulted in DDs being made 40 min faster (95% CI -42.2 to -36.6, I=0%) compared with the group receiving usual care, including central laboratory testing. This in turn resulted in a reduction in LOS for patients who were subsequently discharged by 34 min (95% CI -63.7 to -5.16). No significant difference in mortality was reported.
Discussion: Although statistical and clinical heterogeneity is evident and only a small number of studies were included in the meta-analysis, our results suggest that POCTs might lead to faster discharge decisions. Future research should be performed in primary care and identify how POCTs can contribute meaningful changes to patient care rather than focusing on healthcare processes.

Background: Health authorities worldwide have invested in digital technologies to establish robust information exchange systems for improving the safety and efficiency of medication management. Nevertheless, inaccurate medication lists and information gaps are common, particularly during care transitions, leading to avoidable harm, inefficiencies, and increased costs. Besides fragmented health care processes, the inconsistent incorporation of patient-driven changes contributes to these problems.

Limited urgent access to board-certified dermatologists drives patients to seek dermatologic care at urgent care centers (UCC). UCC are staffed by clinicians with comparatively limited dermatology training, often resulting in lower quality care for acute dermatology conditions. Using a retrospective cohort of 839 referrals, this study investigates health care referral outcomes for patients seeking dermatologic care at UCC.

The study aimed to assess the efficacy and safety of rivaroxaban in outpatient settings compared to inpatient treatment.
Methods: A propensity score-matched comparison with a historical inpatient population was performed based on a retrospective analysis of patients with deep vein thrombosis and without pulmonary embolism treated as outpatients with oral rivaroxaban.

Heart failure (HF) is a global health issue, contributing significantly to morbidity and mortality, particularly in North America. The management of HF is complex, requiring diligent monitoring to prevent decompensation and clinical progression. While there have been improvements in treating HF, it still leads to significant negative health outcomes and heavily contributes to the use of healthcare services.

Background: Guideline-directed medical therapy (GDMT) reduces events in patients with heart failure (HF) with reduced ejection fraction (HFrEF). Despite this impact, underutilization of GDMT persists. This report sought to describe HF management in Canadian outpatients treated at specialized HF clinics (HFCs).
