e13890 Background: Many oncology practices have reported continued use of telemedicine since onset of the COVID-19 pandemic. However, the future sustainability of telemedicine within oncology practices remains unclear, particularly because federal policies that enabled adoption in response to the public health emergency (PHE) have not been made permanent. Understanding similarities and differences in telemedicine utilization at high-volume oncology centers is crucial for shaping evidence-based policy that enables equitable access to oncology care across varying geographies. Methods: This is a cross-sectional, year-over-year, retrospective cohort analysis of trends in telemedicine utilization across all medical oncology clinical appointments conducted among adult patients (age >18) from January 2019 to December 2023 at Stanford Medicine Cancer Center (SM) – comprising multiple campuses in the California Bay Area – and the Mayo Clinic Comprehensive Cancer Center (MC) – a multiregional cancer practice with tertiary referral campuses in Minnesota, Florida, and Arizona, as well as community-based clinics throughout the Upper Midwest. Results: Both institutions exhibited a similar trend in telemedicine adoption over time. This was characterized by an initial surge in utilization following the PHE declaration in March 2020, followed by sustained utilization rates from 2021 to 2023. However, telemedicine use as a proportion of the overall practice differed significantly between institutions. At SM, the rate of telemedicine visits as a proportion of overall clinical practice was 60.3% (49,136/ 81,502) in 2021, 59.9% (52,247/ 87,215) in 2022, and 57.2% (55,007/ 96,163) in 2023. At MC, the proportion of telemedicine utilization was 12.8% in 2021 (23,873/186,086), 14.7% in 2022 (28,985/196,777), and 14.0% in 2023 (30,208/215,941). Deployment in the setting of new versus return visits also differed between institutions. In 2023, telemedicine accounted for 53.7% (6,440/11,998) of new and 57.7% (48,567/84,165) of return visits at SM, compared to 15.5% (3,359/21,728) and 13.8% (26,849/194,213) at MC. Additionally, while video visits were the predominant modality used to conduct telemedicine visits at both institutions from 2021 onward, in 2023 phone visits still made up 17.9% (5,394/30,208) of all telemedicine visits at MC, compared to just 5.4% (2,990/55,007) at SM. Conclusions: Stanford Medicine and Mayo Clinic exhibited a pattern of initial growth of telemedicine adoption in 2020, followed by sustained utilization from 2021-2023. We observed unique differences in the overall proportion, visit type deployment, and modality of telemedicine utilization between institutions. However, this study confirms telemedicine visits have remained a fixture of medical oncology care for many patients at these institutions since the COVID-19 pandemic.

Background: Patients suffering post operative myocardial infarction (PMI) have higher mortality and morbidity rates than observed with non-PMI subsets. Little is known about the true incidence of PMI and how PMI differs from non-PMI with regard to clinical presentation, management and outcome. Methods: We examined the incidence and outcomes of patients with PMI in 1212 subjects (≥65 years) undergoing hip fracture surgery from 1988 – 2002 using a population-based retrospective cohort study from the Rochester Epidemiology Project in Olmstead County, Minnesota. PMI was defined on the basis of cardiac biomarker and/or electrocardiographic evidence of definitive MI within 7 days post operatively. Results: PMI occurred in 170 (14.0%) patients yet only 36 (21.2 %) patients had one or more clinical symptoms suggesting coronary ischemia. One or more classic symptoms of myocardial infarction were present in 26 (15.3%) including shortness of breath (SOB) in 18 (10.6%), chest/arm pain in 11 (6.5%), nausea/vomiting in 8 (4.7%) and diaphoresis in 1 (0.6%). Delirium was present in 15 (8.8%) patients. Median hospital length of stay was longer (10.0 vs. 8 days, p<0.01) and the in-hospital mortality rate was significantly higher (14.1% vs. 1.6%, p<0.001) among patients who had PMI within 7 days. Conclusion: The clinical presentation of PMI differs from non-PMI in the elderly undergoing hip fracture surgery. Most patients were asymptomatic or had atypical clinical presentations. We observed a significantly higher rate of hospital mortality among those experiencing a PMI. Further studies are necessary to better understand the presentation, optimal management and prevention of PMI. Table 1. Study Population Table 2.

Abstract Purpose To evaluate the impact of a collaborative intervention by pharmacists and primary care clinicians on total cost of care, including costs of inpatient readmissions, emergency department visits, and outpatient care, at 30, 60, and 180 days after hospital discharge in a population of patients at high risk for readmission due to polypharmacy. Methods A retrospective study of cost outcomes in a cohort of adult patients discharged from a single institution from July 1, 2013 to March 25, 2016, was conducted. All patients had at least 10 medications listed on their discharge list, including at least 1 drug frequently associated with adverse events leading to hospital readmission. About half of the cohort (n = 496) attended a postdischarge visit involving both a pharmacist and a primary care clinician (a physician, physician assistant, or licensed nurse practitioner); this was designated the pharmacist/clinician collaborative (PCC) group. The remainder of the cohort (n = 500) attended a visit without pharmacist involvement; this was designated as the usual care (UC) group. Costs were compared using a quantile regression to assess the potential heterogeneous impacts of the PCC intervention across different parts of the cost distribution. All outcomes were adjusted for differences in baseline characteristics. Results At 30 days post index discharge, there was a significant decrease in total costs in the 10th and 90th cost quantiles in the PCC cohort vs the UC cohort, without a statistically significant decrease in the 25th, 50th or 75th quantiles. The difference was significant in the 75th and 90th quantiles at 60 days and in the 25th, 50th, and 75th quantiles at 180 days. There was a nonsignificant cost reduction in all other quantiles. Conclusion Medically complex patients had a significantly lower total cost of care in approximately half of the adjusted cost quantiles at 30, 60, and 180 days after hospital discharge when they had a PCC visit. PCC visits can improve patient clinical outcomes while improving cost metrics.

Importance: A postoperative video telemedicine follow-up program was introduced by the Mayo Clinic. An attempt was made to understand the potential cost savings to patients before contemplating full-scale expansion across all potentially eligible surgical patients and practices. Objective: The primary purpose was to estimate potential cost savings to patients with video telemedicine follow-up to home compared with face-to-face follow-up in a standard clinic setting. Design: The research was designed collaboratively by the Center for Connected Care and the surgical practice to address the question of estimated cost savings of postoperative video telemedicine visits. The intervention arm is the postoperative video telemedicine follow-up visit to home setting and the comparator is the face-to-face visit at Mayo Clinic. Setting: Large, integrated, academic multispecialty practice supporting patient care delivery, research, and education. Participants: The population under study comprised routine uncomplicated postoperative patients who underwent video telemedicine or face-to-face follow-up visits that fell within the 90-day global period across multiple (general, neurosurgery, plastic, thoracic, transplant, and urology) surgical specialties. Main Outcome(s) and Measure(s): Economic outcomes were cost of travel, accommodations, meals, and missed work. Additional outcomes included time expenditure and patient satisfaction. Cost/benefit analysis unit was US dollars (USD). All costs were inflated to 2018 USD, using the Gross Domestic Product Implicit price deflator. Results: Patients who utilized video telemedicine rather than face-to-face clinic visit for postoperative follow-up were estimated to save $888 per visit on average. More specifically, patients residing more than 1,635 miles round trip from clinic saved an estimated $1,501 per visit and patients not needing accommodation still saved an estimated $256 per visit. Patient satisfaction over video telemedicine postoperative follow-up visits remained high over the 6-year period of study. Conclusions and Relevance: The use of video telemedicine for routine uncomplicated postoperative follow-up visits to replace face-to-face follow-up visits has the potential to be financially advantageous for patients. Key points Question: For postoperative patients, what are the health economic outcomes associated with video telemedicine follow-up to home compared with face-to-face follow-up in a standard clinic setting? Findings: Video telemedicine offers a cost benefit for patients through avoidance of travel costs and missed work. Meaning: For uncomplicated routine postoperative follow-up visits, video telemedicine is a less costly alternative for most patients.

Objectives To determine the incidence and 1‐year outcomes of an elderly population with perioperative atrial arrhythmia (PAA) within 7 days of hip fracture surgery. Design Retrospective cohort study. Setting The Rochester Epidemiology Project (REP). Participants Elderly adults consecutive undergoing hip fracture repair from 1988 to 2002 in Olmsted County, Minnesota (N = 1,088, mean age 84.0 ± 7.4, 80.2% female). Measurements Baseline clinical variables were analyzed in relation to survival using Cox proportional hazards methods for comparison. Results Sixty‐one participants (5.6%) developed PAA within the first 7 days. During 1 year of follow‐up, 239 (22%) participants died. PAA was associated with greater mortality (45% vs 21%; hazard ratio (HR) = 2.8, 95% confidence interval (CI) = 1.9–4.2). Other mortality risk factors were male sex (HR = 2.0, 95% CI = 1.5–2.6), congestive heart failure (HR = 2.1, 95% CI = 1.7–2.8), chronic renal insufficiency (HR = 2.0, 95% CI = 1.5–2.8), dementia (HR = 2.9, 95% CI = 2.2–3.7), and American Society of Anesthesiologists risk Class III, IV, or V (HR = 3.3, 95% CI = 1.9–5.9). Conclusion Elderly adults undergoing hip fracture surgery who develop PAA within 7 days have significantly higher 1‐year mortality than those who do not. Further studies are indicated to determine whether prevention of PAA will reduce mortality in this population.

Objectives To quantify the occurrence of myocardial infarction ( MI ) occurring in the early postoperative period after surgical hip fracture repair and estimate the effect on 1‐year mortality. Design A population‐based, historical cohort study of individuals who underwent surgical repair of a hip fracture that used the computerized medical record linkage system of the R ochester E pidemiology P roject. Setting Academic and community hospitals, outpatient offices, and nursing homes in O lmsted C ounty, M innesota. Participants Over the 15‐year study period (1988–2002), 1,116 elderly adults underwent surgical repair of a hip fracture. Measurements At the end of the first 7 days after hip fracture repair, participants were classified into one of three groups: clinically verified MI (cv‐ MI ), subclinical myocardial ischemia, and no myocardial ischemia. One‐year mortality was compared between these groups. Multivariate models assessed risk factors for early postoperative cv‐ MI and 1‐year mortality. Results Within the first 7 days after hip fracture repair, 116 (10.4%) participants experienced cv‐ MI and 41 (3.7%) subclinical myocardial ischemia. Overall 1‐year mortality was 22%, with no difference between those with subclinical myocardial ischemia and those with no myocardial ischemia. One‐year mortality for those with cv‐ MI (35.8%) was significantly higher than for the other two groups. Occurrence of early postoperative cv‐ MI , male sex, and history of heart failure or dementia were independently associated with greater 1‐year mortality, whereas prefracture home residence and preoperative higher hemoglobin were protective. Conclusion Rates of early postoperative, cv‐ MI after hip fracture repair exceed rates after other major orthopedic surgeries and are independently associated with greater 1‐year mortality.

Background— Little is known about the impact of technological and pharmacological advances on long-term outcome after percutaneous coronary intervention in general clinical practice. Methods and Results— We analyzed in-hospital and long-term outcome of 24 410 percutaneous coronary interventions among 18 575 unique patients who underwent percutaneous coronary intervention at Mayo Clinic over 25 years. The study population was divided into group 1 (n=3708), coronary interventions from 1979 to 1989; group 2 (n=7020), interventions from 1990 to 1996; group 3 (n=10 952), interventions from 1996 to 2003; and group 4 (n=2730), interventions from 2003 to 2004. Despite the fact that patients in groups 3 and 4 were significantly older, sicker, and had greater prevalence of comorbid conditions, heart failure, and previous revascularization than those in groups 1 and 2, procedural success in groups 3 and 4 improved significantly (94%) versus groups 2 (89%) and 1 (78%) ( P <0.001). Significant reduction in in-hospital mortality (groups 4 to 1: 1.8%, 1.7%, 2.6%, 3.0%; P <0.001) and need for emergency bypass surgery (groups 4 to 1: 0.4%, 0.5%, 1.6%, 5%; P <0.001) was noted in groups 3 and 4 compared with groups 1 and 2. Better adherence to currently recommended evidence-based medications for secondary prevention was seen in the recent time periods. After adjustment, significant reduction in follow-up mortality (hazard ratio, 0.81 and 0.74 for groups 3 and 4, respectively); death or myocardial infarction (hazard ratio, 0.80 and 0.75 for groups 3 and 4, respectively); death, myocardial infarction, or revascularization (hazard ratio, 0.76 and 0.58 for groups 3 and 4, respectively) was noted in recent time periods. Conclusions— Despite higher-risk profiles of patients who underwent percutaneous coronary intervention in recent time periods, procedural success as well as in-hospital and long-term outcomes improved significantly over the last 25 years.
