Impact of Expanding Telephonic Codes in a State Medicaid Program During COVID-19.

Background: The recent pandemic caused by the 2019 novel coronavirus (COVID-19) resulted in declaration of a national emergency (NE) in March 2020. The Centers for Medicare and Medicaid Services quickly responded with temporary expansion of telehealth coverage policies. Aim: To determine the impact of implementing a temporary telephonic code set in a state Medicaid population by comparing the utilization patterns of telehealth claims before and after a NE announcement. Methods: This was a retrospective cohort study conducted with the Arizona Medicaid program, the Arizona Health Care Cost Containment System (AHCCCS). Data include telehealth claims submitted to AHCCCS between January and May 2020 by contracted managed care organizations. Results: Approximately 2.3 million telehealth claims were analyzed in this study. Utilization of the audio-visual (A/V) modality increased 1,610% and telephonic visits increased 408% compared with pre-NE. Compared with pre-NE, three provider type groups increased their utilization of telephonic visits from 1.8% to 50.8% as a result of the temporary telephonic set post-NE. Rural counties had higher rates of telephonic modality adoption, whereas urban counties adopted the A/V modality more readily. Ten telephonic codes constituted 87% of all telehealth claims, with the majority of those codes used for behavioral health and established office visit types. Conclusion: The telephonic modality was adopted more frequently in rural areas and the A/V modality in urban areas. There were several new provider types utilizing telehealth as a result of the temporary telephonic code set implementation.

Prescription medications with actionable pharmacogenomic recommendations in Veterans Health Administration patients.

Aim: To evaluate the prevalence of medications with actionable pharmacogenomic (PGx) safety and efficacy recommendations in patients receiving care from the Veterans Health Administration. Materials & methods: Outpatient prescription data from 2011 to 2021 and any documented adverse drug reactions (ADRs) were reviewed for those who received PGx testing at one Veterans Administration location between November 2019 and October 2021. Results: Among the reviewed prescriptions, 381 (32.8%) were associated with an actionable recommendation based on the Clinical Pharmacogenetics Implementation Consortium (CPIC) prescribing guidelines, with 205 (17.7%) for efficacy concerns and 176 (15.2%) for safety concerns. Among those with a documented ADR for a PGx-impacted medication, 39.1% had PGx results that aligned with CPIC recommendations. Conclusion: Medications with actionable PGx recommendations for safety and efficacy concerns are received with similar frequency, and most patients who have undergone PGx testing at the Phoenix Veterans Administration have received medications that may be impacted by PGx testing.

Cell surface display of poliovirus receptor on Escherichia coli, a novel method for concentrating viral particles in water.

The lack of efficient methods for concentrating viruses in water samples leads to underreporting of viral contamination in source water. A novel strategy for viral concentration was developed using the expression of target virus receptors on bacterial cells. Poliovirus type 1, the most studied enterovirus, was used as a surrogate for enteric viruses. The human poliovirus receptor (hPVR) gene was expressed on the surface of Escherichia coli cells by using the ice nucleation protein (INP) gene. The hPVR gene was ligated to the 3' end of the INP gene after the removal of the stop codon. The resulting open reading frame (ORF) was used for the projection of hPVR onto the outer membrane of E. coli. Gene expression was tested by SDS-PAGE, Western blot, and dot blot analyses, and virion capture ability was confirmed by transmission electron microscopy. The application of engineered E. coli cells for capturing viruses in 1-liter samples of source and drinking water resulted in 75 to 99% procedural recovery efficiency. Cell surface display of viral receptors on bacterial cells opens a new prospect for an efficient and inexpensive alternative tool for capturing and concentrating waterborne viruses in water samples.

Implementation of low-dose CT screening in two different health care systems: Mount Sinai Healthcare System and Phoenix VA Health Care System.

Implementation of lung screening (LS) programs is challenging even among health care organizations that have the motivation, the resources, and more importantly, the goal of providing for life-saving early detection, diagnosis, and treatment of lung cancer. We provide a case study of LS implementation in different healthcare systems, at the Mount Sinai Healthcare System (MSHS) in New York City, and at the Phoenix Veterans Affairs Health Care System (PVAHCS) in Phoenix, Arizona. This will illustrate the commonalities and differences of the LS implementation process in two very different health care systems in very different parts of the United States. Underlying the successful implementation of these LS programs was the use of a comprehensive management system, the Early Lung Cancer Action Program (ELCAP) Management SystemTM. The collaboration between MSHS and PVAHCS over the past decade led to the ELCAP Management SystemTM being gifted by the Early Diagnosis and Treatment Research Foundation to the PVAHCS, to develop a "VA-ELCAP" version. While there remain challenges and opportunities to continue improving LS and its implementation, there is an increasing realization that most patients who are diagnosed with lung cancer as a result of annual LS can be cured, and that of all the possible risks associated with LS, the greater risk of all is for heavy cigarette smokers not to be screened. We identified 10 critical components in implementing a LS program. We provided the details of each of these components for the two healthcare systems. Most importantly, is that continual re-evaluation of the screening program is needed based on the ongoing quality assurance program and database of the actual screenings. At minimum, there should be an annual review and updating. As early diagnosis of lung cancer must be followed by optimal treatment to be effective, treatment advances for small, early lung cancers diagnosed as a result of screening also need to be assessed and incorporated into the entire screening and treatment program.

Cognitive requirements for primary care providers during the referral process: Information needed from and interactions with an electronic health record system.

OBJECTIVES: This study sought to identify and describe the cognitive requirements and associated information needs of referring primary care providers (PCPs) during the referral process as well as characterize referring PCPs' experiences with current health information technology. MATERIALS AND METHODS: We interviewed 62 referring PCPs. Our four-member analysis team used hierarchical task analysis to construct a goal-directed hierarchy. We utilized extensions of the task analysis to describe PCPs' common experiences with health information technologies throughout the referral process. RESULTS: The resultant goal hierarchy includes one main goal (Referral for Additional Care), two sub-goals (Assess Patient's Condition and Manage Referrals), and four major tasks with respective decisions (What consultation is warranted; What information should I provide; What additional action is needed; and How to integrate specialists' findings). Approximately 22 information needs were commonly identified and PCPs described their use of various sources - other PCPs, electronic health records, chat software, and paper- to satisfy those information needs. CONCLUSION: Cognitive demand for referring PCPs is high throughout the referral process. They have to search, identify, compose, track, and integrate information across multiple screens, systems, and people. Existing interfaces do not adequately support the communication, information exchange, or care coordination related to the referral process. Results from this study provide an important foundation for developing patient-centered displays that support PCPs' decision-making process and reduce cognitive challenges.
