RESUMEN
Policy Points Accurate and reliable data systems are critical for delivering the essential services and foundational capabilities of public health for a 21st -century public health infrastructure. Chronic underfunding, workforce shortages, and operational silos limit the effectiveness of America's public health data systems, with the country's anemic response to COVID-19 highlighting the results of long-standing infrastructure gaps. As the public health sector begins an unprecedented data modernization effort, scholars and policymakers should ensure ongoing reforms are aligned with the five components of an ideal public health data system: outcomes and equity oriented, actionable, interoperable, collaborative, and grounded in a robust public health system.

Policy Points The predominantly fee-for-service reimbursement architecture of the US health care system contributes to waste and excess spending. While the past decade of payment reforms has galvanized the adoption of alternative payment models and generated moderate savings, uptake of truly population-based payment systems continues to lag, and interventions to date have had limited impact on care quality, outcomes, and health equity. To realize the promise of payment reforms as instruments for delivery system transformation, future policies for health care financing must focus on accelerating the diffusion of value-based payment, leveraging payments to redress inequities, and incentivizing partnerships with cross-sector entities to invest in the upstream drivers of health.

Policy Points Cities, which are where the majority of the world's population lives today, directly and indirectly shape human health and well-being. Urban health research, policy, and practice are increasingly using a systems science approach to address the upstream and downstream drivers of health in cities, which include social and environmental factors, features of the built environment, conditions of living, and health care resources. To guide future scholarship and policy, we propose an urban health agenda for 2050 focused on revitalizing the sanitation movement, integrating data, scaling best practices, adopting the Health in All Policies approach, and addressing intraurban health inequities.

Importance: In the US, nearly all medical devices progress to market under the 510(k) pathway, which uses previously authorized devices (predicates) to support new authorizations. Current regulations permit manufacturers to use devices subject to a Class I recall-the FDA's most serious designation indicating a high probability of adverse health consequences or death-as predicates for new devices. The consequences for patient safety are not known. Objective: To determine the risk of a future Class I recall associated with using a recalled device as a predicate device in the 510(k) pathway. Design and Setting: In this cross-sectional study, all 510(k) devices subject to Class I recalls from January 2017 through December 2021 (index devices) were identified from the FDA's annual recall listings. Information about predicate devices was extracted from the Devices@FDA database. Devices authorized using index devices as predicates (descendants) were identified using a regulatory intelligence platform. A matched cohort of predicates was constructed to assess the future recall risk from using a predicate device with a Class I recall. Main Outcomes and Measures: Devices were characterized by their regulatory history and recall history. Risk ratios (RRs) were calculated to compare the risk of future Class I recalls between devices descended from predicates with matched controls. Results: Of 156 index devices subject to Class I recall from 2017 through 2021, 44 (28.2%) had prior Class I recalls. Predicates were identified for 127 index devices, with 56 (44.1%) using predicates with a Class I recall. One hundred four index devices were also used as predicates to support the authorization of 265 descendant devices, with 50 index devices (48.1%) authorizing a descendant with a Class I recall. Compared with matched controls, devices authorized using predicates with Class I recalls had a higher risk of subsequent Class I recall (6.40 [95% CI, 3.59-11.40]; P<.001). Conclusions and Relevance: Many 510(k) devices subjected to Class I recalls in the US use predicates with a known history of Class I recalls. These devices have substantially higher risk of a subsequent Class I recall. Safeguards for the 510(k) pathway are needed to prevent problematic predicate selection and ensure patient safety.

Policy Points Hospital-at-Home (HaH) is a home-based alternative for acute care that has expanded significantly under COVID-19 regulatory flexibilities. The post-pandemic policy agenda for HaH will require consideration of multistakeholder perspectives, including patient, caregiver, provider, clinical operations, technology, equity, legal, quality, and payer. Key policy challenges include reaching a consensus on program standards, clarifying caregivers' issues, creating sustainable reimbursement mechanisms, and mitigating potential equity concerns. Key policy prescriptions include creating a national surveillance system for quality and safety, clarifying legal standards for care in the home, and deploying payment reforms through value-based models.

Nearly two-thirds of cancer patients are treated with radiation therapy (RT), often with the intent to achieve complete and permanent tumor regression (local control). RT is the primary treatment modality used to achieve local control for many malignancies, including locally advanced cervical cancer, head and neck cancer, and lung cancer. The addition of concurrent platinum-based radiosensitizing chemotherapy improves local control and patient survival. Enhanced outcomes with concurrent chemoradiotherapy may result from increased direct killing of tumor cells and effects on nontumor cell populations. Many patients treated with concurrent chemoradiotherapy exhibit a decline in neutrophil count, but the effects of neutrophils on radiation therapy are controversial. To investigate the clinical significance of neutrophils in the response to RT, we examined patient outcomes and circulating neutrophil counts in cervical cancer patients treated with definitive chemoradiation. Although pretreatment neutrophil count did not correlate with outcome, lower absolute neutrophil count after starting concurrent chemoradiotherapy was associated with higher rates of local control, metastasis-free survival, and overall survival. To define the role of neutrophils in tumor response to RT, we used genetic and pharmacological approaches to deplete neutrophils in an autochthonous mouse model of soft tissue sarcoma. Neutrophil depletion prior to image-guided focal irradiation improved tumor response to RT. Our results indicate that neutrophils promote resistance to radiation therapy. The efficacy of chemoradiotherapy may depend on the impact of treatment on peripheral neutrophil count, which has the potential to serve as an inexpensive and widely available biomarker.

Diverse tumor metabolic phenotypes are influenced by the environment and genetic lesions. Whether these phenotypes extend to rhabdomyosarcoma (RMS) and how they might be leveraged to design new therapeutic approaches remains an open question. Thus, we utilized a Pax7Cre-ER-T2/+; NrasLSL-G12D/+; p53fl/fl (P7NP) murine model of sarcoma with mutations that most frequently occur in human embryonal RMS. To study metabolism, we infuse 13C-labeled glucose or glutamine into mice with sarcomas and show that sarcomas consume more glucose and glutamine than healthy muscle tissue. However, we reveal a marked shift from glucose consumption to glutamine metabolism after radiation therapy (RT). In addition, we show that inhibiting glutamine, either through genetic deletion of glutaminase (Gls1) or through pharmacological inhibition of glutaminase, leads to significant radiosensitization in vivo. This causes a significant increase in overall survival for mice with Gls1-deficient compared to Gls1-proficient sarcomas. Finally, Gls1-deficient sarcomas post-RT elevate levels of proteins involved in natural killer cell and interferon alpha/gamma responses, suggesting a possible role of innate immunity in the radiosensitization of Gls1-deficient sarcomas. Thus, our results indicate that glutamine contributes to radiation response in a mouse model of RMS.

Background: Medical device recalls are initiated in response to safety concerns. Class I (highest severity) recalls imply a reasonable likelihood of serious adverse events or death associated with device use. Recalled devices must be identified, assessed, and corrected or removed, upon which a recall can be terminated. Objective: To characterize Class I medical device recalls and corresponding recalled devices. Methods: This was a cross-sectional study of Class I recalls posted on the Food and Drug Administration's annual log from January 1, 2018 to June 30, 2022 for moderate-risk and high-risk medical devices. Devices were categorized by therapeutic use, need for implantation, and life-sustaining designation; recalls were categorized by reason, status, and time elapsed. Results: There were 189 unique Class I medical device recalls, including 151 (79.9%) for moderate-risk and 34 (18.0%) for high-risk devices. Sixty-five (34.4%) recalls were for cardiovascular devices, 36 (19.0%) for implanted devices, and 37 (19.6%) for life-sustaining devices. The median number of device units recalled in the US per recall notice was 4620 (interquartile range [IQR], 578-42,591), with 11 (5.8%) recalls associated with more than 1 million device units. Overall, 125 (66.1%) devices had multiple recalls, with a median of 4 (IQR, 3-11) recalls issued per recalled device. As of September 15, 2022, 50 (26.5%) recalls were terminated, with a median of 24 (IQR, 17.3-30.8) months elapsed between recall initiation and termination. Recalls were terminated more commonly among devices recalled once compared to those recalled multiple times (36.2% vs 19.2%; p=0.02) and for recalls that recommended discontinuing further use of affected devices compared to those that recommended device assessment and/or education of affected population (31.8% vs 18.2%; p=0.04). Conclusion: High-severity medical device recalls are common and affect millions of device units annually in the US. Recall termination takes a significant amount of time, putting patients at risk for serious safety concerns.
RESUMEN
Importance: Strengthening premarket and postmarket surveillance of medical devices has long been an area of focus for health policy makers. The recent class I recall (the most serious of the US Food and Drug Administration [FDA] recalls) of reperfusion catheters manufactured by Penumbra, a US-based medical device company, illustrates issues of device safety and oversight that mandate attention. Objectives: To review the regulatory history and clinical evidence of the Penumbra JET 7 Reperfusion Catheter with Xtra Flex Technology (JET 7) and use the device recall as a case study of the challenges associated with clinical evaluation, transparency, and oversight of medical devices in the US. Evidence: Regulatory history and clinical evidence for the Penumbra medical devices were analyzed through a qualitative review of decision letters in the Access FDA database for medical devices and medical device reports in the Manufacturer and User Facility Device Experience database and a review of market data (eg, earnings calls, company communications) and clinical literature. Findings: The JET 7 device was subjected to a class I recall following more than 200 adverse event reports, 14 of which involved patient deaths. Regulatory analysis indicated that each of the Penumbra reperfusion catheters was cleared under the 510(k) pathway (which allows devices to be authorized with limited to no clinical evidence), with limited submission of either new clinical or animal data. Clinical evidence for Penumbra devices was generated from nonrandomized, single-arm trials with small sample sizes. The regulatory issues raised by JET 7 are reflective of broader challenges for medical device regulation. Opportunities for reform include strengthening premarket evidence requirements, requiring safety reporting with unique device identifiers, and mandating active methods of postmarket surveillance. Conclusions and Relevance: The case study of JET 7 highlights the long-standing gaps in medical device oversight and renews the impetus to build on the Institute of Medicine recommendations and reform FDA medical device regulation to protect public health.
