RSM 1.0 user's guide: A resupply scheduler using integer optimization

The Resupply Scheduling Model (RSM) is a PC based, fully menu-driven computer program. It uses integer programming techniques to determine an optimum schedule to replace components on or before a fixed replacement period, subject to user defined constraints such as transportation mass and volume limits or available repair crew time. Principal input for RSJ includes properties such as mass and volume and an assembly sequence. Resource constraints are entered for each period corresponding to the component properties. Though written to analyze the electrical power system on the Space Station Freedom, RSM is quite general and can be used to model the resupply of almost any system subject to user defined resource constraints. Presented here is a step by step procedure for preparing the input, performing the analysis, and interpreting the results. Instructions for installing the program and information on the algorithms are given

COVID-19 Patient Primary Care Survey, Series 1 Fielded May 4-11, 2020

"I greatly appreciated my doc proactively sending out email to all his patients at the beginning and twice since letting us know the concerns with our specific chronic illness and what we need to do to protect ourselves. This has a lot to do with why I trust him so much." On Monday, May 4th, 2020, The Larry A. Green Center launched its first weekly Quick COVID-19 Primary Care Survey to assess the impact of COVID-19 on patients.These are the results from Series 1.https://deepblue.lib.umich.edu/bitstream/2027.42/155448/1/C19 Patient Series 1 National Executive Summary with comments.pdfDescription of C19 Patient Series 1 National Executive Summary with comments.pdf : Main Articl

COVID-19 Patient Primary Care Survey, Series 4 Fielded August 17th, 2020

Despite the challenges presented by the pandemic, 2 of every 3 people surveyed contacted their primary care doctor in July/August. COVID-19 has led to patients seeking care through a variety of different outlets, many making use of multiple options: phone, e-mail, and video, with 38% reporting in-person visits. The use of telehealth has become more widely accepted: 52% report that they feel it’s easier to get care with phone/video options and 56% hope that these options are available after the pandemic. While telehealth has provided an outlet for some, financial concerns or general fear of catching COVID-19 have led to a delay in routine patient care for others. These are the results from Series 4.http://deepblue.lib.umich.edu/bitstream/2027.42/168425/1/C19 Patient Series 4 National Executive Summary.pdfDescription of C19 Patient Series 4 National Executive Summary.pdf : Main ArticleSEL

COVID-19 Patient Primary Care Survey, Series 2 Fielded May 22-25, 2020

"Affordability was the largest obstacle to primary care access: 40% report “limiting their medical care” due to cost concerns." On Monday, May 4th, 2020, The Larry A. Green Center launched its first weekly Quick COVID-19 Primary Care Survey to assess the impact of COVID-19 on patients.These are the results from Series 2.https://deepblue.lib.umich.edu/bitstream/2027.42/155558/1/C19 Patient Series 2 National Summary with comments.pdfDescription of C19 Patient Series 2 National Summary with comments.pdf : Main Articl

Quick Covid-19 Primary Care Survey, Series 23

As we begin month 9 of the pandemic, primary care is weaker, patients are sicker, and the pandemic is raging more fiercely. For months, medical groups have raised alarms about the escalating consequences on patients of failing to adequately support primary care during the pandemic: excess mortality, preventable worsening of non-COVID related health conditions, high levels of mental anguish, growing social needs, and surging pandemic misinformation. The impact of inaction is clear. More than half of clinicians report severe/near severe levels of practice stress and growing patient health burden due to delayed or inaccessible care. Nine months in, COVID-19 is again surging, 63% of practices have staff out due to illness or quarantine, 1 in 5 lack sufficient testing supplies, and over half report increased patient distrust of medical information from public leaders.http://deepblue.lib.umich.edu/bitstream/2027.42/163524/1/C19 Series 23 National Executive Summary.pdfDescription of C19 Series 23 National Executive Summary.pdf : Main ArticleSEL

COVID-19 Patient Primary Care Survey, Series 7, Fielded May 13-26th, 2021

Not everyone in the US has hit vaccination targets set by the federal government. Low-income populations and those living in rural areas are 15% less likely to be vaccinated than the general population. Vaccine hesitancy remains a significant obstacle with over 60% of those unvaccinated reporting they are vaccine hesitant or resistant. Vaccine hesitancy was 10% higher among low-income respondents, rural respondents, and parents of children under 18. Among parents surveyed, 60% were vaccine hesitant or resistant. High rates of trust for primary care, as reported by vaccine resistant populations, suggest primary care may be a key asset to overcome vaccination challenges. These are the results from Series 7.http://deepblue.lib.umich.edu/bitstream/2027.42/169165/1/C19 Patient Series 7 National Executive Summary.pdfDescription of C19 Patient Series 7 National Executive Summary.pdf : Main ArticleSEL

OVID-19 Patient Primary Care Survey, Series 6

In a March 2021 survey fielded during the pandemic, over half of patients report increased anxiety or depression and most report a decrease in their mental health status. Further, low income and rural communities reported poor access to critical services, e.g., low-income respondents had over 50% greater difficulty putting food on the table as compared to the general population. Yet at a time of increased isolation and adversity, two-thirds of those surveyed felt strongly connected to their primary care doctor. Most (78%) have been in contact with their doctor during the pandemic, with over half identifying primary care as the place they called when they needed someone to trust. These are the results from Series 6.http://deepblue.lib.umich.edu/bitstream/2027.42/168419/1/C19 Patient Series 6 National Executive Summary.pdfDescription of C19 Patient Series 6 National Executive Summary.pdf : Main ArticleSEL

Quick Covid-19 Primary Care Survey, Series 24

Primary care, the foundation of our fragile health system, is on the verge of collapse. Even as a COVID-19 vaccine becomes available, primary care faces serious threats to its capacity to triage and treat. Over half (60%) of surveyed clinicians report their patients’ health, unrelated to COVID-19, has worsened. Practices are suffering – 91% have some form of personnel shortage, 61% have severe/near severe practice stress, and 41% have staff positions they cannot fill. Primary care is critical to vaccine distribution, yet only 5% have a full plan for distribution.http://deepblue.lib.umich.edu/bitstream/2027.42/163767/1/C19 Series 24 National Executive Summary.pdfDescription of C19 Series 24 National Executive Summary.pdf : Main ArticleSEL

Quick Covid-19 Primary Care Survey, Series 25

COVID-19 vaccines are now available, yet primary care remains a largely untapped resource in vaccine administration. 99% of clinician respondents believe primary care should be helping with vaccine distribution, yet only 1 in 5 are currently involved. 6 in 10 practices are willing and ready to assist with vaccine distribution but face obstacles, such as lack of storage, staffing, or PPE required. This despite the fact that primary care can help reach vulnerable and at-risk patients and has vast vaccine experience. Among respondents, 20% were practicing in rural communities, and 17% were caring for almost exclusively Medicaid covered patients, and 6 in 10 had patient panels in which at least 75% patients have multiple chronic conditions.http://deepblue.lib.umich.edu/bitstream/2027.42/166302/1/C19 Series 25 National Executive Summary.pdfDescription of C19 Series 25 National Executive Summary.pdf : Main ArticleSEL
