BACKGROUND

Wildfire activity is predicted to increase in many parts of the world due to changes in temperature and precipitation patterns from global climate change. Wildfire smoke contains numerous hazardous air pollutants and many studies have documented population health effects from this exposure.

OBJECTIVES

We aimed to assess the evidence of health effects from exposure to wildfire smoke and to identify susceptible populations.

METHODS

We reviewed the scientific literature for studies of wildfire smoke exposure on mortality and on respiratory, cardiovascular, mental, and perinatal health. Within those reviewed papers deemed to have minimal risk of bias, we assessed the coherence and consistency of findings.

DISCUSSION

Consistent evidence documents associations between wildfire smoke exposure and general respiratory health effects, specifically exacerbations of asthma and chronic obstructive pulmonary disease. Growing evidence suggests associations with increased risk of respiratory infections and all-cause mortality. Evidence for cardiovascular effects is mixed, but a few recent studies have reported associations for specific cardiovascular end points. Insufficient research exists to identify specific population subgroups that are more susceptible to wildfire smoke exposure.

CONCLUSIONS

Consistent evidence from a large number of studies indicates that wildfire smoke exposure is associated with respiratory morbidity with growing evidence supporting an association with all-cause mortality. More research is needed to clarify which causes of mortality may be associated with wildfire smoke, whether cardiovascular outcomes are associated with wildfire smoke, and if certain populations are more susceptible.

BACKGROUND AND OBJECTIVES

There is growing interest in efforts to enhance advance care planning for patients with kidney disease. Our goal was to elicit the perspectives on advance care planning of multidisciplinary providers who care for patients with advanced kidney disease.

DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS

Between April and December of 2014, we conducted semistructured interviews at the Department of Veterans Affairs Puget Sound Health Care System with 26 providers from a range of disciplines and specialties who care for patients with advanced kidney disease. Participants were asked about their perspectives and experiences related to advance care planning in this population. Interviews were audiotaped, transcribed, and analyzed inductively using grounded theory.

RESULTS

The comments of providers interviewed for this study spoke to significant system-level barriers to supporting the process of advance care planning for patients with advanced kidney disease. We identified four overlapping themes: (1) medical care for this population is complex and fragmented across settings and providers and over time; (2) lack of a shared understanding and vision of advance care planning and its relationship with other aspects of care, such as dialysis decision making; (3) unclear locus of responsibility and authority for advance care planning; and (4) lack of active collaboration and communication around advance care planning among different providers caring for the same patients.

CONCLUSIONS

The comments of providers who care for patients with advanced kidney disease spotlight both the need for and the challenges to interdisciplinary collaboration around advance care planning for this population. Systematic efforts at a variety of organizational levels will likely be needed to support teamwork around advance care planning among the different providers who care for patients with advanced kidney disease.

Tobacco companies have begun to acquire pharmaceutical subsidiaries and recently started to market nicotine replacement therapies, such as Zonnic nicotine gum, in convenience stores. Conversely, tobacco companies are producing tobacco products such as tobacco chewing gum and lozenges that resemble pharmaceutical nicotine replacement products, including a nicotine pouch product that resembles snus pouches. This convergence of nicotine and tobacco product marketing has implications for regulation and tobacco cessation.
