Antimicrobial Resistance Burden and Stewardship in Public Hospitals

Escalating antimicrobial resistance poses severe clinical and financial threats to public hospital systems facing elevated infectious disease burdens and diagnostic constraints. Institutional antimicrobial stewardship programs and structured point prevalence surveillance provide vital mechanisms to mitigate broad-spectrum overuse and reduce extended surgical prophylaxis. Strengthening national action plan execution and professional stewardship competencies is essential to preserve therapeutic efficacy in resource-constrained public healthcare settings.

Goal of work

Examine the burden of antimicrobial resistance and institutional stewardship implementation across public hospitals in resource-constrained regional settings.

Methodology

Comparative narrative synthesis of multi-hospital point prevalence studies, clinical audit data, and institutional policy reports across public facilities.

Scientific novelty

Contextualizes empirical prescribing variations and structural deficits in public hospital stewardship against regional national action plan milestones.

Introduction

Antimicrobial resistance represents a critical threat to global public health, imposing substantial burdens on healthcare expenditure, morbidity, and patient survival across hospital systems [1]. Public healthcare institutions in developing regions, particularly across sub-Saharan Africa, experience intense selective pressure driven by high infectious disease co-morbidities and systemic vulnerabilities [2, 3]. Inpatient environments frequently exhibit extensive exposure to broad-spectrum antimicrobial therapies due to infrastructural constraints [5]. Establishing systematic surveillance and intervention protocols within these public facilities is vital to preserve existing therapeutic arsenals [8]. Inpatient prescribing dynamics are characterized by widespread reliance on empiric regimens, driven by delayed microbiological diagnostics, financial hurdles, and variable diagnostic capacities [3, 8]. Furthermore, extended prophylactic administration beyond standard clinical thresholds, notably in surgical departments, compounds therapeutic selective pressure across secondary and tertiary facilities [6, 7]. The fragmented operationalization of national action plans and institutional stewardship structures further diminishes clinical oversight in public settings [2, 5]. Healthcare practitioners frequently report low structural support and limited formal training in stewardship principles, undermining rational prescribing initiatives [4]. This research examines the interplay between antimicrobial resistance burdens and institutional stewardship interventions within public hospital frameworks. Synthesizing secondary evidence from regional point prevalence surveys and health system evaluations provides a rigorous foundation to assess prescribing patterns, structural deficits, and institutional bottlenecks [1, 5]. By comparing public hospital utilization metrics against international stewardship benchmarks, this investigation clarifies the operational barriers to effective antibiotic governance [6, 8]. The resulting synthesis establishes evidence-based insights to reinforce institutional stewardship and optimize clinical outcomes in public healthcare [2, 7].

5.1. Translating Point Prevalence Surveillance into Sustainable Clinical Action

The synthesis of regional evidence confirms that institutional antimicrobial stewardship programmes require more than isolated audit exercises to curb resistance trajectories in public healthcare facilities. Point prevalence surveys provide essential baseline documentation of prescribing patterns, yet their diagnostic utility remains constrained when public facilities lack reliable microbiological infrastructure and rapid turnaround times (Saleem et al., 2021). While national action plans advocate restrictive and enabling formulary controls, systemic disparities between tertiary teaching facilities and peripheral public hospitals hinder the consistent translation of policy into bedside practice (Godman et al., 2022). Furthermore, interprofessional dynamics frequently restrict pharmacy-led interventions, as hierarchical clinical cultures and diagnostic uncertainty drive physicians toward empirical broad-spectrum coverage and prolonged prophylactic regimens (Kalungia et al., 2019). A persistent research gap emerges regarding longitudinal post-intervention assessments; prevailing scholarship predominantly relies on cross-sectional audits, thereby obscuring whether episodic stewardship campaigns produce enduring behavioural modifications among prescribers. Methodological limitations within this synthesis involve reliance on published secondary datasets that display variable reporting standards, inconsistent stratification of surgical prophylaxis durations, and potential publication bias toward better-resourced tertiary centres. Addressing these structural vulnerabilities necessitates institutionalising routine feedback loops, dedicated stewardship funding, and mandatory multidisciplinary antimicrobial management teams across public health networks.
