ABSTRACT Background Lung cancer (LC) and respiratory failure (RF) are leading causes of adult mortality worldwide. Analyzing long‐term mortality trends across demographic, racial, geographic, and socioeconomic groups is essential to address disparities and enhance outcomes. This study investigates US national mortality patterns for LC and RF from 1999 to 2023, focusing on changes in age‐adjusted mortality rates (AAMRs) and key disparities. Methods Mortality data from the CDC WONDER database (1999–2023) for adults aged 25+ with LC (ICD‐10: C34) or RF (ICD‐10: J96) were analyzed. AAMRs per 100,000 were calculated, stratified by gender, race/ethnicity, region, state, and urban–rural status. Temporal trends were assessed using Joinpoint regression to estimate annual percent changes (APCs) with 95% confidence intervals (CIs), with significance at p < 0.05. Results Over 1999–2023, 456,325 deaths from LC and RF were recorded. AAMRs declined from 1999 to 2010 (APC = −1.2, 95% CI: −1.6 to −0.9) but rose from 2010 to 2023 (APC = 1.4, 95% CI: 1.1–1.7). Men's AAMRs steadily decreased, whereas women's dropped initially, then increased from 2011 to 2023 (APC = 2.0, 95% CI: 1.7 to 2.5). Non‐Hispanic Whites saw a sharp AAMR rise from 2014 to 2017 (APC = 2.7, 95% CI: 0.9 to 3.3), with other racial/ethnic groups showing mixed trends. Regionally, the Northeast had the highest AAMRs (8.6, 95% CI: 8.5 to 8.7), and the Midwest the lowest (7.1, 95% CI: 7.0 to 7.1). Metropolitan areas saw increases post‐2006, whereas nonmetropolitan areas rose after 2009 (APC = 2.3, 95% CI: 1.8–3.1). Mississippi had the highest state AAMR (14.0, 95% CI: 13.7–14.4), Wisconsin the lowest (3.7, 95% CI: 3.5–3.8). Conclusion LC and RF mortality declined until 2010, then increased, revealing significant disparities. Targeted interventions are critical to address these trends and reduce inequities.

ABSTRACT Background and Aims Out‐of‐hospital cardiac arrest stands as the primary cause of worldwide mortality. Therefore, all healthcare workers must comprehensively understand and practically apply cardiopulmonary resuscitation (CPR). To address the paucity of literature on this subject, we conducted a nationwide survey among healthcare professionals in Pakistan. Methods This nationwide cross‐sectional study was based on an online questionnaire. The sample pool comprised healthcare professionals and medical students from all over Pakistan. The survey comprised 18 questions aimed to assess the comprehension of CPR, determine the source of their basic life support (BLS) training, and evaluate their competence in performing CPR in real‐life situations. Results The sample size consisted of 951 participants from Pakistan. A total of 712 responders (75%) reported having received CPR or CPR with an Automated External Defibrillator (AED) course, and the same percentage reported that their respective universities had organized the course. The responders reported that the BLS course was made mandatory in only 60% of cases. Most of the respondents were first‐year medical students (21%) and postgraduates (21%). Most of the respondents (78%) professed that the courses had been theoretical as well as practical, and 66% felt confident enacting CPR in out‐of‐hospital settings. Overall, no province was able to achieve a score of greater than 50% when assessed about their knowledge regarding cardiac arrest and CPR. Conclusion This study provides a detailed insight into Pakistan healthcare workers' CPR knowledge and perceptions belonging to different provinces, institutes, designations, and specialties. The participants reported being confident in performing CPR but demonstrated gaps when assessed regarding the revised guidelines and their performance in different scenarios. There is room for further research in overcoming the language barriers and other discrepancies faced by this study.
