Healthcare utilization and adverse outcomes stratified by sex, age and long-term care residency using the Alberta COVID-19 Analytics and Research Database (ACARD): a population-based descriptive study

Risk analysis and assessment method for infectious diseases based on information entropy theory

Infectious diseases risk is directly related to human life safety. After the COVID-19 pandemic, people have paid unprecedented attention to the risk of infectious diseases. Compared with treatment after the outbreak of the epidemic, identifying the influencing factors of infectious disease risk and quantitatively analyzing and assessing infectious disease risk before the outbreak of the epidemic plays an equally important role. This article focuses on the risk of irregular outbreaks of infectious diseases. On the one hand, a method based on information gain is proposed to calculate the weight of environmental factors directly related to infectious disease risk, to clarify the correlation between environmental factors and infectious disease risk. On the other hand, the risk calculation method based on risk weight number is proposed to calculate the risk level of different infectious diseases under the influence of specific environmental factors. Finally, the effectiveness and feasibility of the proposed method are verified through case analysis and discussion. By comparing it with other risk assessment methods, the advantages and disadvantages of the proposed method are demonstrated.

Symptoms and medical resource utilization of patients with bronchiectasis after SARS-CoV-2 infection

Background

The impact of COVID-19 caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) on patients with bronchiectasis in terms of symptoms, self-management and medical resource utilization was unknown.

Objective

To describe the impact of infection by SARS-CoV-2 on fluctuation of symptoms, self-management and medical resource utilization of patients with bronchiectasis during the pandemic of COVID-19.

Methods

This was a single-center cross-sectional questionnaire study performed in Peking University Third Hospital. An online questionnaire investigation addressing the impact of SARS-CoV-2 infection on respiratory symptoms, self-management and medical resource utilization was conducted among patients with bronchiectasis during the COVID-19 surge in December 2022 in Beijing, China.

Results

Five hundred patients with bronchiectasis, with 285 (57%) females, and a mean (± S D ) age of 57.9 ± 15.1 years, completed the telephone questionnaire. The reported prevalence of COVID-19 was 81.2% (406/500). Of the 406 COVID-19 patients, 89.2% experienced fever lasting mostly for no more than 3 days, 70.6 and 61.8% reported exacerbated cough and sputum production respectively, and 17.7% reported worsened dyspnea. Notable 37.4% of the patients with COVID-19 experienced symptoms consistent with the definition of an acute exacerbation of bronchiectasis. However, 76.6% (311/406) of the infected patients did not seek medical care but managed at home. Of the patients who visited hospitals, 26.3% (25/95) needed hospitalization and 2.1% (2/95) needed ICU admission. Multi-factors logistic regression analysis showed that younger age (p = 0.012) and not using a bronchodilator agent(p = 0.022) were independently associated with SARS-CoV-2 infection, while a history of exacerbation of bronchiectasis in the past year (p = 0.006) and daily use of expectorants (p = 0.002) were associated with emergency visit and/or hospitalization for patients with bronchiectasis after SARS-CoV-2 infection.

Conclusion

During the COVID-19 surge, the infection rate of SARS-CoV-2 in patients with bronchiectasis was high, and most of the patients experienced new-onset or exacerbated respiratory symptoms, but only a minority needed medical visits. Our survey results further underscore the importance of patients' disease awareness and self-management skills during a pandemic like COVID-19.

Survey of Peritoneal Dialysis Patients' Challenges and Experiences during the COVID-19 Pandemic: A Multicenter Study in the United States

Key Points

The adjustments made by the dialysis units during the peak of the pandemic were effective in maneuvering the challenges faced by our patients during the COVID-19 pandemic. Patients who remained on PD were satisfied with the quality of care, felt supported by the unit staff, and did not report feeling anxious or depressed.

Background

During the coronavirus disease 2019 (COVID-19) pandemic, adjustments were made to peritoneal dialysis (PD) practices in the outpatient units. These were decisions made by dialysis providers, clinical staff, and governments with input from patient organizations in some instances. The patient perspective regarding these changes during the pandemic has not been explored. We sought to evaluate patient experiences and perceptions of the challenges they faced, institutional adjustments, and their mental health during the height of the COVID-19 pandemic in the United States.

Methods

We conducted a cross-sectional survey of PD patients across four home dialysis units affiliated with four large academic centers, who were on PD between March 2020 and March 2021.

Results

Ninety-eight participants completed the survey across the four outpatient PD clinics. Over 95% of patients did not have to change their home accommodations during the pandemic, and over 80% did not have issues getting their dialysis supplies and medications delivered. Ninety-three percent of patients felt comfortable coming to the dialysis unit if they needed to during the pandemic. Almost all patients (98%) felt supported by their dialysis staff during the peak of COVID-19 and had modified Patient Health Questionnaire 2 (91%) and Generalized Anxiety Disorder 2-item (96%) scores not consistent with depression or anxiety. Less than 10% of patients considered changing their dialysis modality.

Conclusions

The adjustments made by the dialysis units during the peak of the pandemic were effective in maneuvering the challenges faced by our patients during the COVID-19 pandemic. Overall, patients who remained on PD were satisfied with the quality of care, felt supported by the unit staff, and did not report feeling anxious or depressed.
