Background and Objectives: The COVID-19 pandemic has led to an unprecedented mental health crisis among workers in the healthcare field, with average burnout rates increasing from about 32% before the pandemic to 46–52% during peak times and post-traumatic stress disorder (PTSD) affecting 24–34% of frontline staff. The primary objective of this article is to synthesize evidence on the prevalence of burnout and PTSD among healthcare workers before and during the COVID-19 pandemic. The secondary objectives are: (a) to examine the mechanisms and empirical evidence linking clinician mental health to medical errors and patient safety outcomes and (b) to analyze the medico-legal implications of this relationship, including malpractice liability, institutional responsibility, and opportunities for policy reform. Materials and Methods: We conducted a narrative review searching PubMed (November 2025–January 2026) using predefined keyword combinations. Inclusion criteria comprised original research, systematic reviews, and meta-analyses examining mental health outcomes or patient safety among clinical staff. Data were synthesized narratively across five thematic domains. Results: Burnout prevalence increased from approximately 32% pre-pandemic to 46–52% during peak periods, with emotional exhaustion reaching 67.5% in some settings. PTSD rates rose to 24–34% among frontline staff, exceeding pre-pandemic levels of 15–20%, with ICU staff particularly affected (27–40%). Substantial overlap exists between conditions (86–98% comorbidity). Physician burnout is associated with 2.72 times higher odds of self-reported errors (95% CI: 2.19–3.37), with each point increase in emotional exhaustion raising the error risk by 5–11%. Mechanisms include cognitive impairment (reduced executive function, g = −0.39; impaired working memory, g = −0.36) and sleep disturbance. Malpractice litigation compounds psychological harm, increasing depression and suicidal ideation. Conclusions: This review, synthesizing data from over 500,000 healthcare workers, demonstrates bidirectional relationships among burnout, PTSD, and medical errors with significant medico-legal ramifications. Addressing this crisis requires systemic interventions including workload management, psychological support, blame-free reporting cultures, and policy reforms balancing accountability with recognition of system-level contributors to error.
