HEARTLAND Protocol: A Tiered Clinical Implementation Toolkit for Primary Care-Led Heart Failure Management in Rural and Resource-Limited Settings

The HEARTLAND Protocol is a proposed clinical implementation toolkit for primary care-led heart failure management in rural and resource-limited settings. Version 3.4.1 is an operational-clarification successor to V3.4, with 39 pages and 58 references; it is not a clinical validation study or a report of patient outcomes. This edition makes community, ambulatory and remote pharmacy participation explicit across resource tiers; distinguishes trained recognition and escalation, qualified assessment and authorized clinical decisions; separates planned consultation, urgent/emergency assessment and advanced-HF/inpatient referral contexts; and retains responsibility until an accepted transfer. Indication, severity, tolerability and safe monitoring determine care goals and timing. Resource tiers describe delivery support, not lower clinical goals, delayed indicated follow-up or exclusion from financial assistance. Historical quality percentages are planning examples, not validated benchmarks or individualized care targets. A local-readiness process and public training pack provide 12 synthetic scenarios, role and coverage worksheets, paper records and respectful-escalation expectations. Two versioned cards clarify operational presentation. Numerical risk, dose, alert and referral rules are unchanged. The deposit includes the PDF, selected source files, public training pack, change notes and checksums. Preparing these materials does not establish staff-training completion or institutional adoption. HEARTLAND remains proposed pending prospective validation. No patient study or real-patient data are included. Publication does not authorize patient care or autonomous medication changes, establish regulatory clearance or privacy/security certification, or represent new signed clinical approval. Separate ambulatory entry, local emergency/oxygen policies, social-support interpretation and institutional staffing/coverage retain their stated requirements. Prototype figures retain review/distribution restrictions. Earlier Toolkit editions and the Cureus article remain preserved. Review-driven revisions do not imply reviewer endorsement. Companion software and audio are separately versioned. Synthetic playback, saved records, notification intents and technical receipts do not establish patient contact, clinical review, understanding, delivered care or continuous monitoring. Automated audio checks are not human-listening certification. This publication does not activate external notification transport or institution-gated background processes.
