Comorbid posttraumatic stress disorder and major depressive disorder are associated with asthma morbidity among World Trade Center workers.

BACKGROUND: World Trade Center (WTC) rescue and recovery workers have a high burden of asthma, comorbid posttraumatic stress disorder (PTSD), and major depressive disorder (MDD). PTSD is associated with worse asthma outcomes. OBJECTIVE: In this study, we evaluated whether the relationship between PTSD and asthma morbidity is modified by the presence of MDD. METHODS: We used data from a cohort of WTC workers with asthma. Asthma control (asthma control questionnaire), resource utilization, and quality of life (asthma quality of life questionnaire) were evaluated. We used regression analyses to evaluate the adjusted association of PTSD and MDD with asthma control, resource utilization, and quality of life. RESULTS: Of the study cohort of 293 WTC workers with asthma, 19% had PTSD alone, 2% had MDD alone, and 12% had PTSD and MDD. Adjusted mean differences (95% confidence interval) in asthma control questionnaire scores were 1.32 (0.85-1.80) for WTC workers with PTSD and MDD, 0.44 (0.03-0.84) for those with PTSD alone, and 0.50 (-0.38 to 1.38) for workers with MDD alone compared with those without MDD or PTSD. WTC workers with PTSD and MDD, PTSD alone, and MDD alone had mean (95% confidence interval) adjusted differences in asthma quality of life questionnaire scores of -1.67 (-2.22 to -1.12), -0.56 (-2.23 to -1.12), and -1.21 (-2.23 to -0.18), respectively, compared with workers without MDD or PTSD. Similar patterns were observed for acute resource utilization. CONCLUSION: PTSD and MDD seem to have a synergistic effect that worsens asthma control and quality of life. Efforts to improve asthma outcomes in this population should address the negative impacts of these common mental health conditions.

The Relationship Between Post-Traumatic Stress Disorder and Self-Management Behaviors in World Trade Center Workers with Asthma.

BACKGROUND: Comorbid posttraumatic stress disorder (PTSD) is highly prevalent and associated with increased morbidity among World Trade Center (WTC) rescue and recovery workers with asthma. However, the potential behavioral pathways underlying this relationship remain unclear. OBJECTIVE: To evaluate whether PTSD is associated with lower adherence to asthma self-management behaviors among WTC workers with asthma. METHODS: We used data from a prospective cohort of WTC workers with a physician diagnosis of asthma who were prescribed controller medications. Presence of comorbid PTSD was determined based on structured clinical interviews. Asthma self-management behaviors included medication adherence, inhaler technique, use of action plans, and trigger avoidance. We conducted unadjusted and multiple regression analyses to evaluate the association of PTSD with asthma self-management. RESULTS: Overall, 30% of 276 WTC workers with asthma had comorbid PTSD. Posttraumatic stress disorder was associated with worse asthma control and poorer quality of life. However, PTSD was not significantly associated with medication adherence (odds ratio [OR] -0.15; 95% confidence interval [CI] -0.5 to 0.2), inhaler technique (OR -0.12; 95% CI -0.7 to 0.5), use of action plans (OR 0.8; 95% CI 0.4 to 1.8), or trigger avoidance (OR 0.9; 95% CI 0.4 to 1.8). CONCLUSIONS: We did not find significant differences in key asthma self-management behaviors between WTC workers with and without PTSD. These results suggest that other mechanisms, such as differences in symptom perception or inflammatory pathways, may explain the association between PTSD and increased asthma morbidity.

Screening for Occupational Lung Cancer: An Unprecedented Opportunity.

Selected occupational populations are at the highest risk of lung cancer, because they smoke at increased rates and are concurrently exposed to workplace lung carcinogens. Low-dose computed tomography (CT)-based lung cancer screening has an enormous potential to reduce lung cancer mortality in these populations, as shown both in the lung cancer screening studies in the general population and in studies of workers at high risk of lung cancer. Pulmonologists can play a key role in identifying workers at high risk of lung cancer and ensuring that they are offered annual low-dose CT scans for early lung cancer detection.

Qualitative Evaluation of Individual and Group Well-Child Care.

OBJECTIVE: Individual well care (IWC) is the standard delivery model for well-child care in the United States. Alternative models, such as group well care (GWC), may create opportunities to enhance care for babies. The purpose of this study was to evaluate parents' perceptions of social/wellness benefits and system challenges of IWC and GWC. METHODS: Since 2014, we have provided both IWC and GWC at an urban academic practice serving a low-income minority community. We conducted a mixed method study involving surveys and 18 focus groups (11 IWC groups, n = 32 parents; 7 GWC groups, n = 33 parents). Parents completed surveys before convening focus group discussions. Survey results were analyzed using independent t tests; focus groups were digitally recorded, transcribed, and analyzed to identify themes. RESULTS: Both groups had similar demographics: parents were mostly female (91%) and black (>80%); about half had incomes < $20,000. Parents' mean age was 27 years; children's mean age was 11 months. There were no significant differences in overall scores measuring trust in physicians, parent empowerment, or stress. IWC parents' themes highlighted ways to improve care delivery, while GWC parents highlighted both satisfaction with care delivery and social/wellness benefits. GWC parents strongly endorsed this model and reported unique benefits, such as garnering social support and learning from other parents. CONCLUSIONS: Parents receiving both models of care identified ways to improve primary care delivery. Given some of the benefits reported by GWC parents, this model may provide the means to enhance resilience in parents and children in low-income communities.
