Low-dose whole-lung irradiation in severe COVID-19 pneumonia: a controlled clinical trial.

INTRODUCTION: The COVID-19 pandemic has caused significant morbidity and mortality thus far. Considering the historical uses of high-voltage X-ray beams for unresolvable pneumonia, we aimed to assess whether low-dose whole-lung irradiation (WLI) could provide any benefits for patients with refractory COVID-19 pneumonia. METHODS: Eleven patients with refractory COVID-19 pneumonia were treated with WLI to a total dose of 1 Gy and compared to 11 patients in a matched control group from June to November 2020. The study's primary endpoint was improvement of chest X-ray severity score (CXRS), followed by changes in mean oxygen (O2) saturation and 28-day mortality as secondary endpoints. RESULTS: The final CXRS was significantly lower in the WLI group (8.7 ± 2.5) compared to the control group (12.3 ± 3.3) (P: 0.016). Change of CXRS from the first to the last chest X-ray was -2.2 ± 3.1 for the WLI group and 0.7 ± 3.9 for the control group, which showed a trend for lower CXRS in the WLI group (U = 30, p: 0.085). Mean O2 saturation showed insignificant improvement in the first 24 hours after radiotherapy (mean difference: 2.5 ± 4.1, Z=-1.6, P value: 0.11). Overall survival after 28 days was 32% in the WLI group and 11% in the control group (P: 0.48). The reason for death in many patients was not merely respiratory failure, but also other adverse situations like pneumothorax, cardiogenic shock and pulmonary thromboembolism. CONCLUSIONS: Low-dose WLI could improve the CXR severity score and O2 saturation in severely ill COVID-19 patients, but larger studies are required to determine its impact on mortality.

Applied techniques for putting pre-visit planning in clinical practice to empower patient-centered care in the pandemic era: a systematic review and framework suggestion.

BACKGROUND: One of the main elements of patient-centered care is an enhancement of patient preparedness. Thus, pre-visit planning assessment tools was emerged to prepare and involve patients in their treatment process. OBJECTIVE: The main objective of this article was to review the applied tools and techniques for consideration of putting pre-visit planning into practice. METHODS: Web of Science, Scopus, IEEE, and PubMed databases were searched using keywords from January 2001 to November 2020. The review was completed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses checklist. Then, qualitative analysis was done to suggest an appropriate framework by mapping the main concepts. RESULTS: Out of 385 citations were retrieved in initial database searches, 49 studies from ten countries were included. Applied pre-visit techniques can be classified into eight categories. Our results showed that almost 81% of studies were related to procedures that were done between each visit, while 42% of articles were related to before visits. Accordingly, the main approach of included articles was patient preparedness. While 38 studies reported this approach is effective, three studies reported the effectiveness of such tools as moderate, only two articles believed it had a low effect on improving patient-centered care. CONCLUSION: This survey summarized the characteristics of published studies on pre-visit planning in the proposed framework. This approach could enhance the quality of patient care alongside enhancement patient-provider communication. However, such an approach can also be helpful to control pandemic diseases by reducing unnecessary referrals.
