Objectives: Telemedicine enables patients to communicate with physicians effectively, especially during the coronavirus disease (COVID-19) pandemic. However, few studies have explored the use of online health care platforms for a comprehensive range of specialties during the COVID-19 pandemic. This study aimed to investigate how telemedicine services were affected by the announcement of human-to-human transmission in China. Methods: Telemedicine data from haodf.com in China were collected. A difference-in-differences analysis compared the number of telemedicine use and the number of active online physicians for different specialties in 2020 with the numbers in 2019, before and after the announcement of human-to-human transmission. Results: …


Disaster Relief And Humanitarian Logistics: Three Essays, Peter H. Imbriale Jan 2023

Disaster Relief And Humanitarian Logistics: Three Essays, Peter H. Imbriale

2023

The increased frequency and impact of natural disasters and other humanitarian crises—including events such as the COVID-19 pandemic—makes studying disaster relief and recovery particularly important. One relevant area of research in this space is humanitarian logistics. This dissertation provides insights into disaster relief logistics by exploring the government’s role in humanitarian logistics, examining the government’s efforts to address COVID-19 medical supply chain challenges, and determining how to lessen the impact of supply chain bottlenecks from unwanted post-disaster donations. Chapter one (sole-authored) is a literature review of the role of governments in humanitarian logistics. Although governments are vital stakeholders in nearly …

Covid‑19 Vaccine Distribution: Exploring Strategic Alternatives For The Greater Good, Arben Asllani, Silvana Trimi

Department of Supply Chain Management and Analytics: Faculty and Staff Publications

The dire state of the COVID-19 pandemic crisis symbolized the urgency for efficient distribution and administration of vaccines to combat the virus as the most urgent public health service. This paper presents a prototype multi-criteria decision support model based on goal programming that can effectively support vaccination plans for the greater good of society. The optimization goals of the model include minimizing the number of fatalities and risk of spreading the disease, while complying with government health agency’s priority guidelines for vaccination. This study applied the model to a real-world dataset to demonstrate how it can be effectively applied as …

This study examines the impact of coronavirus disease 2019 (COVID-19) test accuracy (i.e., sensitivity and specificity) on the progression of the pandemic under two scenarios of limited and unlimited test capacity. We extend the classic susceptible–exposed–infectious–recovered model to incorporate test accuracy and compare the progression of the pandemic under various sensitivities and specificities. We find that high-sensitivity tests effectively reduce the total number of infections only with sufficient testing capacity. Nevertheless, with limited test capacity and a relatively high cross-infection rate, the total number of infected cases may increase when sensitivity is above a certain threshold. Despite the potential for …


Headquarters Report: A Look Back, A Step Forward, Karen Burgess Cae Feb 2022

Headquarters Report: A Look Back, A Step Forward, Karen Burgess Cae

The Journal of the Michigan Dental Association

In her Headquarters Report, MDA Executive Director Karen Burgess reflects on the dental landscape entering the third year of the COVID-19 pandemic, acknowledging the "new normal" with increased demand for services, staff shortages, and supply chain challenges. Despite uncertainties, the Michigan Dental Association (MDA) maintained membership numbers better than expected, with a slight decrease in market share. The report emphasizes the importance of member value, highlighted by a favorable Net Promoter Score (NPS) and positive feedback on MDA benefits. It also discusses efforts in diversity, equity, and inclusion, along with successful advocacy initiatives influencing oral health in Michigan.

The novel coronavirus disease 2019 (COVID-19) has caused a global pandemic. Some studies have suggested a negative association between sunlight intensity and COVID-19 infection, alluding to the belief that it might be safe to go out on sunny days. This paper examined whether solar radiation mitigated the association between human mobility and COVID-19 infection in Europe using a dynamic panel data model to investigate the effect of human mobility, solar radiation, and their interaction on COVID-19 infection. The results revealed that outgoing mobility was positively correlated and solar radiation was negatively correlated with COVID-19 infection at lag levels of 1, …

Problem definition: This work focuses on the hotel housekeeping process. In a field study, a possible channel of disease transmission between consecutive guests in hotel rooms is revealed. In order to prevent the transmission, an innovative assembly-line housekeeping method is developed. Academic/practical relevance: The transmission of infectious diseases during hotel stays (e.g., by touching unclean towels or bed linens) has been reported globally. Under the current COVID-19 pandemic, having contact with saliva or mucus left by an infected person could cause infection. The standard housekeeping process used by the majority of hotels leaves a channel for new towels and bed …
