Background. Environmental factors such as weather variables contribute to asthma exacerbation. The impact of meteorological factors on asthma-related hospital admissions (HAs) or emergency department visits (EDVs) has been assessed in the literature. We conducted a systematic review to establish a conclusion of whether these findings from the literature are consistent and generalizable or if they vary significantly by certain subgroups. Objective. This study aims to review the effect of meteorological variables on asthma HAs and EDVs in adults, to identify knowledge gaps and to highlight future research priorities. Method. A systematic search was conducted in electronic databases such as PubMed, Embase, and CINAHL. All studies published in English were screened and included if they met the eligibility criteria. Two independent reviewers assessed the quality of the studies and extracted the data. The available evidence was summarized and presented using a harvest plot. Results. Our initial search returned a total of 3887 articles. After screening titles, abstracts, and full texts, 16 studies were included. Thirty-one percent of the included studies (5/16) found that temperature was the only factor associated with asthma hospitalization or EDVs. Six studies (37%) found that both temperature and relative humidity were associated with HAs. Four studies (25%) identified thunderstorms as a possible factor associated with asthma hospitalization in adults. Conclusion. Our review suggests that HAs and EDVs due to asthma are associated with many meteorological factors. Among the articles included in this review, changing temperature is the most commonly studied variable. We did not find studies that measured barometric pressure, weather phenomena, or the effect of tornados. To develop effective strategies to protect subjects at risk, further studies are required.

Background Patient-centered care (PCC) is an emerging priority in many healthcare settings but lacks clarity in the emergency department (ED). It is of interest to know what PCC practices are most important to patients to better their experience. The objective of this study was to conduct a mixed-methods systematic review of PCC in the ED. Methods We used stakeholder and patient engagement to consult with clinicians, subject-matter experts, patient partners, and community organizations to determine patient needs. We examined all articles in the ED context with PCC as the intervention. Two independent reviewers screened 3136 articles and 13 were included. A meta-ethnographic analysis was conducted to determine common themes of PCC. Results Themes included emotional support, communication, education, involvement of patient/family in information sharing and decision making, comfort of environment, respect and trust, continuity, and transition of care. Challenges in the ED reflected a lack of PCC. Moreover, implementation of PCC had many benefits including higher patient satisfaction with their care. Though there were commonalities of PCC components, there was no consistently used definition for PCC in the ED. Conclusion The findings of this review support the evidence that PCC is of high value to the ED setting and should be standardized in practice.
