Rapid Implementation of a Complex, Multimodal Technology Response to COVID-19 at an Integrated Community-Based Health Care System.

BACKGROUND: The rapid spread of severe acute respiratory syndrome coronavirus-2 or SARS-CoV-2 necessitated a scaled treatment response to the novel coronavirus disease 2019 (COVID-19). OBJECTIVE: This study aimed to characterize the design and rapid implementation of a complex, multimodal, technology response to COVID-19 led by the Intermountain Healthcare's (Intermountain's) Care Transformation Information Systems (CTIS) organization to build pandemic surge capacity. METHODS: Intermountain has active community-spread cases of COVID-19 that are increasing. We used the Centers for Disease Control and Prevention Pandemic Intervals Framework (the Framework) to characterize CTIS leadership's multimodal technology response to COVID-19 at Intermountain. We provide results on implementation feasibility and sustainability of health information technology (HIT) interventions as of June 30, 2020, characterize lessons learned and identify persistent barriers to sustained deployment. RESULTS: We characterize the CTIS organization's multimodal technology response to COVID-19 in five relevant areas of the Framework enabling (1) incident management, (2) surveillance, (3) laboratory testing, (4) community mitigation, and (5) medical care and countermeasures. We are seeing increased use of traditionally slow-to-adopt technologies that create additional surge capacity while sustaining patient safety and care quality. CTIS leadership recognized early that a multimodal technology intervention could enable additional surge capacity for health care delivery systems with a broad geographic and service scope. A statewide central tracking system to coordinate capacity planning and management response is needed. Order interoperability between health care systems remains a barrier to an integrated response. CONCLUSION: The rate of future pandemics is estimated to increase. The pandemic response of health care systems, like Intermountain, offers a blueprint for the leadership role that HIT organizations can play in mainstream care delivery, enabling a nimbler, virtual health care delivery system that is more responsive to current and future needs.

The Effect Of The Hospital Readmissions Reduction Program On Readmission And Observation Stay Rates For Heart Failure.

The Hospital Readmissions Reduction Program reduces Medicare prospective payments for hospitals with excess readmissions for selected diagnoses. By comparing data for patients who were readmitted or placed on observation status immediately before and immediately after the thirty-day cutoff for penalties, we sought to determine whether hospitals have responded to the program by shifting readmissions for heart failure to observation status. We used regression discontinuity, taking advantage of the cutoff to generate unbiased estimates of treatment effects. Overall, we found no evidence that the program has affected the use of observation stays. However, for nonpenalized hospitals, the use of observation status was 5.4 percent higher for patients returning to the hospital immediately before the thirty-day cutoff than for patients returning immediately after the cutoff, which suggests that some hospitals may have used observation status to help avoid penalties. Because differences in the cost-sharing rules may lead to higher out-of-pocket expenses for Medicare patients placed on observation status, the program could have an inequitable financial impact.

Survival Analysis of Cancer Patients With FIGO Stage IIIA Endometrial Cancer.

OBJECTIVE: Endometrial cancer patients with positive serosa and/or adnexae (FIGO stage IIIA) have a variable prognosis and are at a significant risk for recurrence. We investigated how tumor characteristics and adjuvant treatments influence the overall survival (OS) and recurrence patterns in these patients and patients with positive cytology alone (previously classified as stage IIIA before 2009). MATERIALS AND METHODS: This multi-institution retrospective study reviewed 55 patients with positive serosa and/or adnexae and 18 patients with positive cytology only, surgically staged from 1990 to 2010. The study cohort was evaluated using the Kaplan-Meier estimates of OS and Cox proportional hazards modeling. RESULTS: The 5-year OS for all IIIA patients was 55%. Administration of adjuvant therapy was associated with improved OS when compared with surgery alone (P=0.0018). The 5-year OS was 20% for patients treated with surgery alone (n=10), 55% with surgery and radiation therapy (n=26), 75% with surgery and chemotherapy (n=7), and 79% with surgery followed by both radiation therapy and chemotherapy (n=12; P=0.005). The tumor characteristics showed that nonendometrioid histology (P=0.0143) and lymph vascular space invasion (P=0.0483) had a poorer OS. Recurrence occurred in 29% of IIIA patients, with 9% locoregional failures and 20% distant failures. Patients with positive cytology only had a similar OS to patients with positive serosa and/or adnexae (76% vs. 55%; P=0.104) and recurrence rate (22% vs. 29%; P=0.4101). CONCLUSIONS: This retrospective study suggests benefit from the use of adjuvant radiotherapy and chemotherapy for stage IIIA patients. We recommend further investigation of adjuvant therapies for IIIA patients in prospective studies and randomized clinical trials.

Survival analysis of endometrial cancer patients with cervical stromal involvement.

OBJECTIVE: Stage II endometrial cancer is relatively uncommon. There is no consensus for appropriate adjuvant therapy in endometrial cancer patients with cervical stromal involvement (International Federation of Gynecology and Obstetrics [FIGO] stage II). This study investigates how adjuvant treatments and tumor characteristics influence overall survival (OS) and disease-free survival (DFS) in stage II patients in order to establish better treatment guidelines. METHODS: This multi-institution, Institutional Review Board approved, study is a retrospective review of 40 endometrial cancer patients with cervical stromal involvement treated from 1993 to 2009. Kaplan-Meier estimates were used to evaluate OS and DFS. RESULTS: OS was 85% at three years and 67% at five years. There were no significant differences in age, histology, depth of invasion, comorbid conditions, surgical staging or recurrence between patients who received radiation therapy (RT) and those who did not. However, patients with FIGO grade 1 cancers were less likely to receive RT (p=0.007). Patients treated with RT had a similar 5 year OS (n=33, 69%) to those treated with surgery only (n=7, 60%, p=0.746). There were no OS differences when evaluating by grade, histology, or depth of invasion between patients who did and did not receive RT. Four patients recurred: three were locoregional failures only, and one failed locally and distant. CONCLUSION: Patients receiving RT had higher grade tumors. Despite this, OS was comparable between the RT and the no RT cohorts. Local failure was the predominant pattern of failure. Endometrial cancer patients with cervical stromal involvement likely receive better locoregional control with the addition of adjuvant RT and we continue to advocate for RT in most cases.

Impact of age cutoffs on a lynch syndrome screening program.

PURPOSE: To determine the impact of applying an age cutoff to tumor-based Lynch syndrome (LS) screening, specifically focusing on changes in relative effectiveness, efficiency, and cost. The project was undertaken to answer questions about implementation of the LS screening program in an integrated health care delivery system. PATIENTS AND METHODS: Clinical data extracted from an internal cancer registry, previous modeling efforts, published literature, and gray data were used to populate decision models designed to answer questions about the impact of age cutoffs in LS screening. Patients with colorectal cancer (CRC) were stratified at 10-year intervals from ages 50 to 80 years and compared with no age cutoff. Outcomes are reported for a cohort of 325 patients screened and includes total cost to screen, LS cases present in the cutoff category, number of LS cases expected to be identified by screening, cost per LS case detected, and total number and percentage of LS cases missed. CONCLUSION: Applying an age cutoff to an LS screening program has considerable potential for decreasing total screening costs and increasing efficiency, but at a loss of effectiveness. Imposing an age cutoff of 50 years reduces the cost of the screening program to 16% of a program with no age cutoff, but at the expense of missing more than half of the cases. Failure to identify LS cases is magnified by a cascade effect in family members. The results of this analysis influenced the final policy in our system.

Survival analysis of endometrial cancer patients with positive lymph nodes.

OBJECTIVE: Patients with endometrial cancer with positive lymph nodes (International Federation of Gynecology and Obstetrics stage IIIC) have a substantially worse prognosis. This study investigates how tumor characteristics and adjuvant treatments influence overall survival (OS) in stage IIIC patients. METHODS: This multi-institution, institutional review board-approved study is a retrospective review of 116 patients with surgically staged endometrial cancer with positive lymph nodes treated from 1995 to 2008. The study cohort was evaluated using Kaplan-Meier estimates of OS and proportional hazard modeling. RESULTS: The 5-year OS for all patients was 51%. Administration of adjuvant therapy was associated with improved OS when compared with surgery alone (P = 0.007). Five-year OS was 40% for patients treated with surgery alone (n = 26), 50% with surgery and chemotherapy (n = 8), 58% with surgery and radiotherapy (n = 43), and 54% with surgery followed by both radiotherapy and chemotherapy (n = 39). Patients who received radiotherapy (n = 82) had improved OS (57%) when compared with patients who did not (n = 34, OS = 42%; P = 0.001). Radiotherapy was associated with improved OS for patients with endometrioid histology, high-grade tumors, and positive para-aortic lymph nodes. Patients with nonendometrioid histology and low-grade tumors who received radiotherapy had a similar OS as those who did not. High-grade tumors (P < 0.001), nonendometrioid histology (P = 0.004), and more than 2 positive lymph nodes (P = 0.01) were associated with a poorer OS. After controlling for patient demographics and tumor characteristics, patients with high-grade tumors and more than 2 positive lymph nodes had a poorer OS, whereas patients who received radiotherapy had improved OS. CONCLUSIONS: This large institutional study of patients with lymph node-positive endometrial cancer identified prognostic factors associated with a poor OS. Radiotherapy was associated with improved survival and may be specifically indicated for patients with endometrioid histology, high-grade tumors, and positive para-aortic lymph nodes. We recommend further investigation of adjuvant therapies in randomized clinical trials.

Is short-interval mammography necessary after breast conservation surgery and radiation treatment in breast cancer patients?

PURPOSE: The optimum timing and frequency of mammography in breast cancer patients after breast-conserving therapy (BCT) are controversial. The American Society of Clinical Oncology recommends the first posttreatment mammogram 1 year after diagnosis but no earlier than 6 months after completion of radiotherapy. The National Comprehensive Cancer Network recommends annual mammography. Intermountain Healthcare currently follows a more frequent mammography schedule during the first 2 years in BCT patients. This retrospective study was undertaken to determine the cancer yield mammography during the first 2 years after BCT. METHODS AND MATERIALS: 1,435 patients received BCT at Intermountain Healthcare between 2003 and 2007, inclusive. Twenty-three patients had bilateral breast cancer (1,458 total breasts). Patients were followed up for 24 months after diagnosis. The 1- and 2-year mammography yields were determined and compared with those of the general screening population. RESULTS: 1,079 breasts had mammography at less than 1 year, and two ipsilateral recurrences (both noninvasive) were identified; 1,219 breasts had mammography during the second year, and nine recurrences (three invasive, six noninvasive) were identified. Of the 11 ipsilateral recurrences during the study, three presented with symptoms and eight were identified by mammography alone. The mammography yield was 1.9 cancers per 1,000 breasts the first year and 4.9 per 1,000 the second year. CONCLUSIONS: These data demonstrate that the mammography yield during the first 2 years after BCT is not greater than that in the general population, and they support the policy for initiating followup mammography at 1 year after BCT.
