Abstract

Background: Cardiopulmonary related mortality is a global, public health crisis. With cardiovascular and respiratory diseases accounting for 31% and 14.3% of global deaths, respectively, these rates continue to increase as air pollution and heat waves become more frequent. Objective: The Navigation Guide methodology for systematic review was used to determine whether there existed a synergistic relationship between high air pollution and high ambient temperature that would increase cardiopulmonary or non-accidental mortality Methods: The steps of the Navigation Guide methodology were followed to determine a study question and a search for studies that fit the inclusion criteria. Each study was assessed for bias and confounding, the quality of the literature was rated, and the strength of evidence was assessed. Results: There were 9 studies identified that met the inclusion criteria. The studies assessed were ecological studies or case-crossover studies. Risk of bias was determined to be “probably low” and the quality of evidence was determined to be “moderate,” with high consistency and precision. No meta-analysis was conducted. Conclusion: Based on the Navigation Guide methodology for systematic review, it was concluded that there is “sufficient” evidence of a synergistic relationship between air pollution and ambient temperature that increases non-accidental mortality.
