Abstract
BACKGROUND Therapeutic drug monitoring (TDM) may be helpful in tailoring treatment with antimicrobials, and expert interpretation of the results may make it more clinically useful. METHOD The study aim was to assess retrospectively the first-year impact (July 2021-June 2022) of a newly established expert clinical pharmacological advice program (ECPA) based on TDM results in tailoring therapy with 18 antimicrobials hospital-wide in a tertiary university hospital. All patients having ≥1 ECPA were grouped in five cohorts [hematology, intensive care unit (ICU), pediatrics, medical- and surgical- wards]. Four indicators of performance were identified [total ECPAs; total ECPA recommending dosing adjustments/total ECPAs both at first and at subsequent assessments; turnaround time (TAT) of ECPAs, defined as optimal (<12h), quasi-optimal (12-24h), acceptable (24-48h), suboptimal (>48h)]. RESULTS A total of 8484 ECPAs were provided for tailoring treatment in 2961 patients, mostly admitted in the ICU (33.8%) and in the medical wards (29.4%). The proportions of ECPAs recommending dosing adjustments were >40% at first assessment (40.9% in hematology; 62.8% in ICU; 53.9% in pediatrics; 59.1% in medical wards; 59.7% in surgical wards), and decreased consistently at subsequent TDM assessments (20.7% in hematology; 40.6% in ICU; 37.4% in pediatrics; 32.9% in medical wards; 29.2% in surgical wards). The overall median TAT of the ECPAs was optimal (8.11h). CONCLUSIONS The TDM-guided ECPA program was successful in tailoring treatment with a wide panel of antimicrobials hospital-wide. Expert interpretation by MD clinical pharmacologists, short TATs and strict interaction with ID consultants and clinicians were crucial in attaining this.

Abstract
Traditional microbiological methodology has limited sensitivity, detection range, and turnaround times in diagnosis of bloodstream infection in Febrile Neutropenia (FN) patients. A more rapid and sensitive detection technology is urgently needed. Here we used the newly developed Nanapore targeted sequencing (NTS) to diagnose the pathogens in blood samples. The diagnostic performance (sensitivity, specificity and turnaround time) of NTS detection of 202 blood samples from FN patients with hematologic disease was evaluated in comparison to blood culture and nested Polymerase Chain Reaction (PCR) followed by sanger sequence. The impact of NTS results on antibiotic treatment modification, the effectivity and mortality of the patients under the guidance of NTS results were assessed. The data showed that NTS had clinical sensitivity of 92.11%, clinical specificity of 78.41% compared with the blood culture and PCR combination. Importantly, the turnaround time for NTS was <24 h for all specimens, and the pre-report time within 6 h in emergency cases was possible in clinical practice. Among 118 NTS positive patients, 98.3% patients' antibiotic regimens were guided according to NTS results. There was no significant difference in effectivity and mortality rate between Antibiotic regimen switched according to NTS group and Antibiotic regimen covering pathogens detected by NTS group. Therefore, NTS could yield a higher sensitivity, specificity and shorter turnaround time for broad-spectrum pathogens identification in blood samples detection compared with traditional tests. It's also a good guidance in clinical targeted antibiotic treatment for FN patients with hematologic disease, thereby emerging as a promising technology for detecting infectious disease.

Abstract
BACKGROUND In the population-based HIV impact assessment surveys, early infant diagnosis (EID) was provided to infants <18 months without a prior diagnosis. For the Namibia population-based HIV impact assessment (NAMPHIA), the GeneXpert platform was assessed for the feasibility of near POC EID testing compared with the standard Roche COBAS AmpliPrep/COBAS TaqMan (CAP/CTM) platform. Quality assurance measures and turnaround time were compared to improve EID results reporting. METHODS NAMPHIA participants were screened for HIV exposure using Determine HIV-1/2 rapid test; samples reactive on Determine received EID testing on the GeneXpert instrument and Xpert HIV-1 Qual assay using whole blood. Results were confirmed at the Namibia Institute of Pathology using dried blood spots on the Roche CAP/CTM platform per national guidelines. RESULTS Of the 762 screened infants, 61 (8.0%) were Determine-reactive and considered HIV-exposed. Of the 61 exposed infants, 2 were found to be HIV-infected whereas 59 were negative on both GeneXpert and Roche platforms, achieving 100% concordance. Average turnaround time was 3.4 days for the Xpert HIV-1 Qual assay, and average time from collection to testing was 1.0 days for GeneXpert compared with 10.7 days for Roche. No samples failed using GeneXpert whereas 1 sample failed using Roche and was repeated. CONCLUSION Quality POC EID testing is feasible in a national survey through extensive training and external quality assurance measures. The use of decentralized POC EID for national testing would provide rapid diagnosis and improve TATs which may prevent loss to follow-up, ensure linkage to care, and improve clinical outcomes for infants.

Abstract
INTRODUCTION Point-of-care (POC) early infant diagnosis (EID) testing has been shown to dramatically decrease turnaround times from sample collection to caregiver result receipt and time to ART initiation for HIV-positive infants compared to centralized laboratory testing. As governments in sub-Saharan Africa implement POC EID technologies, we report on the feasibility and effectiveness of POC EID testing and the impact of same-day result delivery on rapid ART initiation within national programmes across six countries. METHODS This pre-/post-evaluation compared centralized laboratory-based (pre) with POC (post) EID testing in 52 facilities across Cameroon, Democratic Republic of Congo, Ethiopia, Kenya, Senegal and Zimbabwe between April 2017 and October 2019 (country-dependent). Data were collected retrospectively from routine records at health facilities for all infants tested under two years of age. Hazard ratios and 95% confidence intervals were calculated to compare time-to-event outcomes, visualized with Kaplan-Meier curves, and the Somers' D test was used to compare continuous outcomes. RESULTS Data were collected for 2892 EID tests conducted on centralized laboratory-based platforms and 4610 EID tests on POC devices with 127 (4%) and 192 (4%) HIV-positive infants identified, respectively. POC EID significantly reduced the time from sample collection to caregiver result receipt (POC median: 0 days, IQR: 0 to 0 vs. centralized: 35 days, IQR: 26 to 56) and time from sample collection to ART initiation for HIV-positive infants (POC median: 1 day, IQR: 0 to 7 vs. centralized: 39 days, IQR: 26 to 57). With POC testing, 72% of infants received results on the same day as sample collection; HIV-positive infants with a same-day diagnosis had six times the rate of ART initiation compared to those diagnosed one or more days after sample collection (HR: 6.39; 95% CI: 3.44 to 11.85). CONCLUSIONS Same-day diagnosis and treatment initiation for infants is possible with POC EID within routine government-led and -supported public sector healthcare facilities in resource-limited settings. Given that POC EID allows for rapid ART initiation, aligning to the World Health Organization's recommendation of ART initiation within seven days, its use in public sector programmes has the potential to reduce overall mortality for infants with HIV through early treatment initiation.

Abstract
Early in the course of the coronavirus infection disease 2019 (COVID-19) pandemic in South Africa, the Department of Health implemented a policy of community screening and testing (CST). This was based on a community-orientated primary care approach and was a key strategy in limiting the spread of the pandemic, but it struggled with long turnaround times (TATs) for the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) reverse transcriptase polymerase chain reaction test. The local experience at Symphony Way Community Day Centre (Delft, Cape Town), highlighted these challenges. The first positive tests had a median TAT of 4.5 days, peaking at 29 days in mid-May 2020. Issues that contributed to long TATs were unavailability of viral transport medium, sample delivery and storage difficulties, staffing problems, scarcity of testing supplies and other samples prioritised over CST samples. At Symphony Way, many patients who tested COVID-19 positive had abandoned their self-isolation because of the delay in results. Employers were unhappy with prolonged sick leave whilst waiting for results and patients were concerned about not getting paid or job loss. The CST policy relies on a rapid TAT to be successful. Once the TAT is delayed, the process of contacting patients, and tracing and quarantining contacts becomes ineffective. With hindsight, other countries’ difficulties in upscaling testing should have served as warning. Community screening and testing was scaled back from 18 May 2020, and testing policy was changed to only include high-risk patients from 29 May 2020. The delayed TATs meant that the CST policy had no beneficial impact at local level.

Abstract
Point-of-care testing (POCT) is the analysis of patient specimens outside the clinical laboratory, near or at the site of patient care, usually performed by clinical staff without laboratory training, although it also encompasses patient self-monitoring. It is able to provide a rapid result near the patient and which can be acted upon immediately. The key driver is the concept that clinical decision making may be delayed when samples are sent to the clinical laboratory. Balanced against this are considerations of increased costs for purchase and maintenance of equipment, staff training, connectivity to the laboratory information system (LIS), quality control (QC) and external quality assurance (EQA) procedures, all required for accreditation under ISO 22870. The justification for POCT depends upon being able to demonstrate that a more timely result (shorter turnaround times (TATs)) is able to leverage a clinically important advantage in decision making compared with the central laboratory (CL). In the four decades since POCT was adapted for the self-monitoring of blood glucose levels by subjects with diabetes, numerous new POCT methodologies have become available, enabling the clinician to receive results and initiate treatment more rapidly. However, these instruments are often operated by staff not trained in laboratory medicine and hence are prone to errors in the analytical phase (as opposed to laboratory testing where the analytical phase has the least errors). In some environments, particularly remote rural settings, the CL may be at a considerable distance and timely availability of cardiac troponins and other analytes can triage referrals to the main centers, thus avoiding expensive unnecessary patient transportation costs. However, in the Emergency Department, availability of more rapid results with POCT does not always translate into shorter stays due to other barriers to implementation of care. In this review, we apply the principles of evidence-based laboratory medicine (EBLM) looking for high quality systematic reviews and meta-analyses, ideally underpinned by randomized controlled trials (RCTs), looking for evidence of whether POCT confers any advantage in clinical decision making in different scenarios.

Abstract
Overcrowding and prolonged patient stays in emergency departments (EDs) affect patients' experiences and outcomes, and increase healthcare costs. One way of addressing these problems is through using point-of-care blood tests, laboratory testing undertaken near patient locations with rapidly available results. D-dimer tests are used to exclude venous thromboembolism (VTE), a common presentation in EDs, in low-risk patients. However, data on the effects of point-of-care D-dimer testing in EDs and other urgent care settings are scarce. This article reports the results of a literature review that examined the benefits to patients of point-of-care D-dimer testing in terms of reduced turnaround times (time to results), and time to diagnosis, discharge or referral. It also considers the benefits to organisations in relation to reduced ED crowding and increased cost effectiveness. The review concludes that undertaking point-of-care D-dimer tests, combined with pre-test probability scores, can be a quick and safe way of ruling out VTE and improving patients' experience.

Abstract
Objective China launched a health care reform policy due to the aging population and rapid urbanization. However, emergency overcrowding is not improved. We assessed the laboratory efficiency of emergency department (ED) in Shanghai hospitals. Methods We recorded the turn around times for processing laboratory biomarkers to assess laboratory efficiency at 17 EDs in national/regional hospitals. We compared TAT between national and regional hospitals and between central and ED laboratories to analyze the relationship between the laboratory efficiency and the ED overcrowding. Results All the participating hospitals have an emergency laboratory. The median TAT for c‐TNT was 61 min (46–76 min) at regional EDs compared with 64 min (46–87 min) at national EDs; therefore, the TAT at regional EDs were more efficient (P < 0.05). The TAT were longer (65 min (53–85 min)) at ED labs than (60 min (42–83 min)) at central labs (P < 0.05), independent of the hospital tier and working period. We discovered that only 9% of investigated samples at Tier II EDs and 5% at Tier III EDs were assayed by point‐of‐care (POC) instruments. Conclusion Our TAT level is approaching the recommended international standard. However, the TAT evaluation from ED laboratories demonstrates that their existence does not decrease the waiting time for laboratory reports compared to central laboratory. Thus, they have not yet approached a level to share the burden of the ED overcrowding. Further arrangement should be assigned to separate the function of emergency laboratory and central laboratory. It is worth deploying the POC assay in the ED, which will save twice the TAT level. The idea of evaluating routine laboratory efficiency by TAT at ED is fast, convenient, although it does not represent the general level of laboratory efficiency.

Abstract
We assessed the efficiency of point-of-care (POC) tests in the emergency department (ED) by comparing them with the international standard. We recorded the turnaround times (TATs) for processing laboratory biomarkers to assess laboratory efficiency from 17 EDs in national/regional hospitals. We also compared patient components between national and regional hospitals. Although the 17 enrolled hospitals expanded their EDs, they contained only five POC machines among them. The P50 (P25, P75) of the TATs for POC tests was 47 min (39, 55.5 min) for cardiac troponin T, which was much longer than the international standard (30 min). The TATs of other cardiac biomarkers were also longer than 30 min. The low efficiency of TATs for POC tests was a common feature in both regional and national hospitals (p > 0.05). Myocardial infarction was diagnosed in 61% of investigated ED patients who visited national hospitals, which is more frequently than those diagnosed at regional hospitals (46%, p < 0.05). Chronic heart failure was less frequent at national hospitals (28%) than at regional hospitals (41%, p < 0.05). The patient distribution in this study indicates that patients have the tendency to choose hospitals when they are affected with chest pain. However, the POC panel is rarely used in the ED, which delayed the TAT level and affected laboratory efficiency. This finding indicates a severe problem in the administrative management of EDs. This issue should be addressed in the next version of the medical reform policy.
