Here are 10 recent papers (2019–2025) that examine barriers or hindrances to point-of-care testing (POCT), with a brief take on each and clear citations.

  1. Barriers across the POCT “value chain.” A broad review synthesizes obstacles at every stage—technology (accuracy, QC), workflow fit, training, data integration, reimbursement, and regulation—and argues that value often stalls at implementation rather than invention. PMC

  2. Adoption hurdles in high-income systems. Perspective review highlights reimbursement uncertainty, evidence of clinical utility, governance/quality oversight, and informatics integration as recurring blockers to POCT uptake—even where devices are available. PMC

  3. Front-line clinicians in a pediatric ED (high-income setting). Qualitative work reports concerns about result accuracy/interpretation, disrupted clinical reasoning, insufficient training, unclear protocols, and unexpected workload when POCT is introduced. BMJ Open

  4. Community perspectives during COVID-19 (testing access). A qualitative U.S. study documents confusion about guidelines, limited accessible sites, perceived swab discomfort, and slow turnaround—barriers that blunt benefits of rapid/POC options. MDPI

  5. Large-scale rapid antigen testing (operational barriers). A population program details logistics, staffing, cost, supply, and reporting challenges when scaling POCT beyond clinics; overcoming these required dedicated coordination infrastructure. Science

  6. Implementation research for SARS-CoV-2 RDTs (schools/organizations). Qualitative synthesis notes training load, workflow redesign, acceptance, and legal/liability questions, underscoring that “easy” tests still demand organizational readiness. PMC

  7. Cardiometabolic POCT in primary care (scoping review using CFIR). Across studies, the most cited barriers were infrastructure constraints, device usability/quality issues, and staffing—workload and training—with facilitators tied to clear protocols and feedback loops. BioMed Central

  8. Primary care without labs in Ghana (field study). In low-resource clinics, barriers included supply chain gaps, user training, lack of supervisory QA, documentation burdens, and referral pathways not aligned with POCT outputs; the paper proposes sustainability tactics (e.g., simplified SOPs, supply dashboards). BioMed Central

  9. Community pharmacy POCT (systematic review). For strep/flu/CRP/COVID POCT, repeated barriers were scope-of-practice ambiguity, reimbursement/commissioning complexity, IT connectivity to records, staff time, and space/privacy. ScienceDirect

  10. Out-of-hospital/EMS settings (qualitative study). Interviews across clinicians and the public surface device portability limits, kit availability, training/competency maintenance, data handoff to hospitals, and medico-legal clarity as major determinants of feasibility. PubMed

Cross-cutting themes (what shows up again and again)

Operational & workforce: lack of training, time, staffing, competency tracking (items 3, 6, 7, 8, 9, 10). Quality & trust: perceived or real accuracy/interpretation concerns and unclear QC/QA (items 2, 3, 7, 9). Integration: weak links to EHR/LIS, reporting, referral pathways (items 2, 5, 8, 9, 10). Economics & policy: reimbursement uncertainty and governance burden (items 2, 5, 9). Access & equity: site accessibility, supply chains, infrastructure (power, space, connectivity) constrain community/LRS deployments (items 4, 5, 7, 8, 10). These factors collectively explain why proven POCTs still under-deliver at scale unless programs pair the device with workflow redesign, training/QA plans, data plumbing, and payment models tailored to the setting.

Executive Summary: Barriers to the Adoption and Effective Use of Point-of-Care Testing (POCT)

Point-of-care testing (POCT) has advanced dramatically over the past decade, offering faster turnaround times, decentralized access, and potential improvements in patient outcomes across clinical and community settings. Yet despite clear technological progress and demonstrated analytic accuracy, widespread integration of POCT into health systems remains limited. This report synthesizes findings from recent literature (2019–2025) across primary care, hospital, community, and low-resource environments to identify the most persistent barriers to adoption and sustainable implementation.

1. Operational and Workforce Constraints
Across nearly all studies, front-line clinicians cited insufficient training, competency maintenance, and workflow compatibility as key barriers. In both high- and low-income settings, implementation was often constrained by staff workload, unclear testing protocols, and lack of protected time for quality control (QC) and device upkeep. Without structured training cycles and defined accountability, test performance and confidence in results deteriorate over time.

2. Quality Assurance and Trust in Results
Even when devices meet regulatory standards, clinicians frequently question accuracy and reproducibility, particularly in comparison to centralized laboratories. The absence of standardized QC frameworks, external proficiency testing, and clear delineation of clinical responsibility (lab vs. ward staff) undermines trust and limits use in critical decision-making.

3. Data Integration and Connectivity
A recurring technical and organizational barrier is poor integration with electronic health records (EHRs) and laboratory information systems (LIS). Manual data entry or paper reporting increases error risk, impedes surveillance, and erodes workflow efficiency. Studies recommend that integration requirements be built into procurement and commissioning frameworks, not retrofitted after deployment.

4. Economic, Regulatory, and Governance Challenges
From primary care to community pharmacies, reimbursement mechanisms are inconsistent or absent. Unclear funding streams, combined with overlapping regulatory and liability frameworks, discourage adoption. Governance models for quality oversight—who owns the data, maintains the equipment, and validates results—remain fragmented, particularly outside hospital systems.

5. Infrastructure and Access Barriers
In low-resource and community settings, logistical issues—supply chain reliability, equipment maintenance, power, and space—limit sustainability. During COVID-19, even well-funded programs faced challenges in supply continuity, reporting obligations, and staff capacity, emphasizing that rapid diagnostics still require robust support infrastructure.

6. Lessons from the COVID-19 Era
Pandemic-era deployment of rapid antigen and molecular POCT highlighted both the potential and fragility of decentralized testing. Implementation success correlated with dedicated coordination structures, automated reporting systems, and clear public communication. These experiences underscore that scale requires as much investment in organizational engineering as in device technology.

7. Strategic Recommendations
To realize the clinical and economic promise of POCT, systems must invest in:

  • Competency-based training and formalized QC oversight.

  • Pre-planned data connectivity and EHR/LIS integration.

  • Defined governance and reimbursement frameworks aligned with national standards.

  • Supply chain and infrastructure resilience for sustained access.

  • Outcome-based evaluation of POCT programs, linking rapid testing to measurable improvements in patient care and resource utilization.

Conclusion
The barriers to POCT adoption are not primarily technological but systemic. Effective implementation depends on aligning innovation with workflow, governance, and reimbursement realities. POCT can transform care only when introduced as part of an integrated diagnostic ecosystem—supported by robust training, connectivity, and accountability frameworks rather than isolated devices.

ChatGPT said:

Here are five additional, non-COVID–focused papers on barriers to point-of-care testing (POCT), with quick takeaways and citations.

  1. Primary care implementation gaps (systematic review).
    Lingervelder et al. mapped how POCT is evaluated and adopted in primary care and found misalignment between what studies report (e.g., analytic performance) and the practical factors GPs need to decide on adoption (workflow fit, training, responsibilities, connectivity), which slows uptake. PMC

  2. Health-economic evidence and adoption.
    A follow-on review by Lingervelder et al. concluded that inconsistent or limited health-economic data (budget impact, real-world cost offsets) hampers commissioning and reimbursement, even when tests show good analytic accuracy—creating a policy/finance barrier to scale. SpringerLink

  3. GPs’ perspectives in Germany (cross-sectional survey).
    Matthes et al. report that German GPs cite time constraints, unclear responsibilities for QC/QA, training/competency maintenance, device costs, and EHR/LIS integration as key barriers; many practices want POCT but lack the infrastructure and governance to use it routinely. BioMed Central

  4. Market/technology landscape and system-level barriers (review).
    Khan et al. critically review POCT across indications and emphasize that regulatory fragmentation, interoperability gaps, supply/logistics, and usability in real settings pose bigger hurdles than sensor chemistry, arguing for early integration plans (IT, QC, training) in procurement. Frontiers

  5. POCT in emergency medical services (scoping review).
    Moore et al. synthesize EMS literature and highlight device portability/robustness, staff training and competency retention, kit availability, and reliable data hand-off to hospitals as persistent barriers; they call for standardized pathways and evaluation frameworks before widescale rollout. BioMed Central

Bonus (useful context, not COVID-specific):

  • Public acceptance and perceptions (survey trend 2020–2022): affordability, trust in reliability, and privacy/logistics still shape adoption beyond pandemics. ScienceDirect

  • What primary care needs next (scoping review/editorial): recent pieces outline practical governance, outcome-linked evaluation, and stakeholder coordination as prerequisites for routine POCT use. Wiley Online Library+1

If you’d like, I can slot these into your appendix and update the evidence table (study, setting, method, barriers, implementation fixes) to keep COVID and non-COVID streams distinct.

Who is S.E.E. mills? She seems important to this field.
ChatGPT said:

Here’s what I was able to discover about Sarah E. E. Mills (sometimes cited as S.E.E. Mills) — she is indeed playing a visible role in research on point-of-care testing (POCT), particularly in primary and out-of-hours primary care settings.

Profile & research focus

  • Mills is listed as Sarah Mills in one of her major recent papers: “Barriers, enablers, benefits, and drawbacks to Point of Care Testing (POCT): a survey of the General Practice Out-of-Hours (GPOOH) Service in Scotland.” Her name there appears as “S.E. Mills”, consistent with the citation you referenced. bjgpopen.org+2University of St Andrews Research Portal+2

  • In that study, her affiliations include the University of St Andrews (School of Medicine) in Scotland. University of St Andrews Research Portal+1

  • The focus of that article is the availability and use of POCT in out-of-hours general practice in Scotland: identifying what tests are present, what clinicians think about them, and what barriers they experience. For example: “Barriers to POC test use were availability of the test kits and machines (94.5 %), training requirements … (71.1 %), interpret results (56.3 %) and time to do the test (62.0 %).” PubMed+1

  • From the article’s metadata: Mills is a “Lecturer in Academic General Practice” at University of St Andrews. University of St Andrews Research Portal+1

  • The outputs indicate she is interested in implementation science aspects of POCT: e.g., what enables or hinders adoption in real-world clinical workflows.

Why she seems important in this field

  • Her research directly addresses the “last mile” of POCT implementation: not only whether a test technically works, but can and does it get used in routine clinical care.

  • The paper is globally relevant (even though located in Scotland) because many of the barriers she identifies—training, device availability, time constraints, workflow disruption—match themes found in other international literature.

  • The fact that her work is recent (2024 in BJGP Open) means she is among the current voices focusing on implementation barriers in primary care/out-of-hours contexts.

Areas where more info might be needed / speculation

  • I did not find a rich public biography of Mills beyond her academic listing; her full career path (prior roles, other major grants) is less visible at present.

  • Her research output appears concentrated on POCT / out-of-hours care. It isn’t clear yet whether she has a large portfolio across many different clinical settings or diseases, though this recent piece is significant.

  • Because she is academic faculty (lecturer level) the scale of her network or how widely cited her work will become remains to be seen—but being published in open access in a peer-reviewed general practice journal suggests growing impact.

If you like, I can look up her full publication list, h-index, and current grants, then send you a mini-bio (1-2 pages) of her and her work in POCT.
