The coronavirus outbreak has evolved into a global issue, with more new cases reported outside of China than in it for the first time since the onset of the disease. The US healthcare system is facing practical implications in dealing with the epidemic, and in this episode, we will discuss these implications with Julie Yu, a6 and Zbio general partner. We will also provide an update on the current situation from our previous episode with Judy Savitskaya. It's important to note that we will not cover the clinical infectious disease specifics in this episode but will bring on experts for that in an upcoming episode. The World Health Organization declared the coronavirus outbreak a public health emergency of international concern on January 30, and the US Health and Human Services Secretary followed suit the next day. The disease is now officially named COVID-19, and it's crucial that the healthcare community responds effectively to contain its spread. Stay tuned for more insights on the practical implications of the COVID-19 outbreak for the US healthcare system.
Identifying and isolating COVID-19 patients in the US healthcare system: The US healthcare system struggles to identify and isolate COVID-19 patients due to lengthy presymptomatic period and lack of clear understanding of risk points, leading to reactive approach and potential virus spread.
The current healthcare system in the US is facing significant challenges in identifying and isolating individuals suspected of having COVID-19. The lengthy presymptomatic period of this virus makes it difficult to identify and isolate contagious individuals before they spread the virus further. When someone enters a hospital, they may be asked about travel history and other potential exposure risks. If it's determined that there's a potential risk, a test may be administered, assuming test kits are available. Quarantine rooms with negative pressure are ideal for isolating potential contagions, but not all facilities have this infrastructure. The chaos on the front lines arises from the lack of clear understanding of risk points and the reactive approach to patient care. We're waiting for patients to show up rather than being proactive in identifying and isolating them. The CMS has developed a new billing code for testing, but the focus remains on improving the identification and isolation process to prevent further spread of the virus.
Investing in innovative vaccines and surge manufacturing capacity for pandemic preparedness: The business model for bringing rapid vaccine innovations to market is uncertain, but investing in R&D and manufacturing capacity is crucial for pandemic preparedness. The unbundling of hospitals could improve access and reduce exposure to illnesses.
While the technology exists to rapidly identify and create vaccines on demand in response to outbreaks, the business model and reimbursement pathways for bringing these innovations to market are still uncertain. The focus is currently on traditional approaches like gowns, goggles, and gloves for disease containment. However, the World Health Organization has emphasized the need for investment in developing innovative vaccines and therapeutics, as well as surge manufacturing capacity, to prepare for potential pandemics. From a systemic perspective, the evolution of hospitals as centralized facilities for scarce resources has resulted in patients traveling long distances and being exposed to other illnesses. The unbundling of hospitals, which could involve bringing advanced medical capabilities to patients' homes, could help address these challenges and improve overall preparedness for health emergencies.
Decentralizing Healthcare with Connected Devices and Interoperable Data Systems: Connected health devices and interoperable data systems are key components of a more decentralized, efficient, and effective healthcare system, enabling data collection and sharing from various sources and improving patient access and convenience.
The healthcare industry is moving towards a more decentralized model, where technologies once confined to hospitals are being productized and made accessible in the community. This shift is driven by the need for convenience and accessibility for patients, especially for those who cannot afford or live near central healthcare facilities. An example of this is connected health devices, such as smart thermometers, which collect data and predict outbreaks, notifying schools, churches, and other institutions in addition to the end users. However, for this decentralized model to work effectively, interoperable data systems are necessary to collect and share data from various sources, including clinical settings and non-traditional sources like connected devices. In the present, hospitals are evolving into health systems, requiring connectivity with primary care and urgent care clinics, and EHRs serve as the primary tool for frontline clinicians. Ultimately, this convergence of interoperability, data liquidity, and data from unconventional sources is paving the way for a more decentralized, efficient, and effective healthcare system.
Decentralizing and Technologically Advancing Healthcare: Hospitals are integrating risk identification into medical records, highlighting the need for a more decentralized and advanced healthcare system. However, epidemics and pandemics expose weaknesses, like the lack of PCR tests, and the need for a more robust system using technology and distributed data.
The ongoing coronavirus outbreak has highlighted the need for a more decentralized and technologically advanced healthcare system to effectively respond to widespread epidemics and pandemics. The discussion revealed that hospitals are now inserting basic questions into medical records to identify potential risks, and this change can be propagated across the entire care delivery system due to the broad infrastructure layer in place. However, this conversation also shed light on the potential nodes of failure in the healthcare system during epidemics and pandemics. Moreover, the World Health Organization's latest report shows a significant increase in confirmed cases due to the inclusion of clinically diagnosed cases, which can only be diagnosed by symptoms and CT scan evidence in the absence of a PCR test. A PCR test, or polymerase chain reaction test, is a method of amplifying a specific sequence of DNA or RNA to detect the presence of a virus or disease. The direction for the future of healthcare is towards decentralization, unbundling of hospitals, and the use of technology and distributed data streams to be more responsive and nimble. The learnings from this epidemic will be applied to create a more robust and prepared healthcare system for the future.
Identifying and Measuring DNA Sequences with Real-time PCR: Real-time PCR is a lab technique used to detect and quantify specific DNA sequences, especially important for identifying RNA viruses like SARS-CoV-2 causing COVID-19. The technique uses a polymerase enzyme to create multiple copies, enabling detection and quantification.
Real-time PCR, also known as quantitative PCR (qPCR), is a laboratory technique used to identify and measure the presence or quantity of specific DNA sequences. This process involves using a polymerase enzyme to create multiple copies of a target sequence, enabling detection and quantification. The distinction between real-time PCR and reverse transcriptase PCR lies in the former's requirement for RNA templates, which necessitates the use of reverse transcriptase to convert RNA into DNA before amplification. The importance of this technique in understanding COVID-19 lies in its ability to detect the presence of the SARS-CoV-2 virus, which is an RNA virus. Additionally, the concept of R0, or the number of people an infected person is likely to spread the virus to, is still uncertain due to the large number of asymptomatic cases and the ongoing global spread of the disease. While some experts argue that we have technically reached a pandemic stage, the definition of a pandemic remains debated.
Understanding Pandemics, Endemics, and Misinfodemics: Pandemics are diseases that spread across multiple geographies, endemics are regularly present in a population or environment, and misinfodemics refer to the spread of both accurate and inaccurate information about a disease, impacting data reliability.
The terms pandemic, endemic, and even misinfodemic are important to understand when discussing diseases like COVID-19. A pandemic refers to a disease that has spread across multiple geographies, but it doesn't necessarily indicate the severity or contagiousness of the disease. Endemic, on the other hand, means that a disease is regularly present in a particular population or environment. Flu is an example of an endemic disease. Misinfodemic refers to the spread of both accurate and inaccurate information about a disease, which can impact the reliability of data used to create models predicting its spread. According to the World Health Organization, the data from China suggested that about 82% of confirmed COVID-19 cases have only mild symptoms, 15% required hospitalization, and 3% needed intensive care. The preliminary data also indicated that about 2% of people who tested positive for the virus have died. Last time, it was discussed that a high fatality rate and a fast-spreading virus are paradoxical, as dead people can't spread the disease and sick people are less mobile. However, the length of the incubation period is another variable to consider. The ongoing infodemic can impact the reliability of data used to create models, making accurate predictions challenging.
Understanding the role of latent and incubation periods in virus spread: Both latent and incubation periods impact a virus's spread and understanding its impact. Short latent, long incubation periods can lead to unknowing spread. Currently, it's uncertain about COVID-19's incubation period, so staying informed and practicing preventative measures is crucial.
The latent period and incubation period of a virus play a significant role in understanding its spread and impact. The latent period refers to the time between being infected and becoming infectious, while the incubation period is the time between infection and the onset of symptoms. If the latent period is short but the incubation period is long, individuals may spread the virus without knowing they are infected. This paradox between case fatality and spread rate can be disrupted, making it difficult to determine the exact impact of the virus. Currently, it's too early to determine the exact incubation period, with most estimates topping out at around 14 days. Therefore, it's crucial to keep track of where cases are being reported and not jump to conclusions about case fatality rates or R naughts. The same precautions apply, and it's essential to stay informed while practicing preventative measures.
