BACKGROUND:High-acuity Medicare beneficiaries with annual expenditures exceeding $12,000 disproportionately drive the total cost of care (TCOC) through preventable acute utilization and are natural candidates for value-based and shared savings arrangements. Whether remote patient monitoring (RPM) produces near-term TCOC reductions in this cost-stratified population has been insufficiently evaluated in real-world practice. METHODS:A retrospective pre-post cohort analysis was conducted among 597 Medicare beneficiaries enrolled for at least 5 months in a technology-enabled RPM program, each with annualized preenrollment TCOC ≥$12,000. Patients received a cellular-enabled blood pressure monitor linked to a HIPAA-compliant platform staffed by licensed care navigators. The primary outcome was change in annualized TCOC over the 12 months before and after program initiation. Given right-skewed cost distribution (skewness = 4.47), the Wilcoxon signed-rank test was the primary inferential procedure. Secondary outcomes included per-1,000-patient rates of emergency department (ED) visits, inpatient hospitalizations, and 30-day readmissions. RESULTS:The mean age was 76.6 ± 8.2 years; 55.6% were female. The median annualized TCOC declined from $25,956 to $11,792, a reduction of $10,932 per patient (Wilcoxon p < 0.001; rank-biserial r = 0.47). The mean TCOC fell from $39,291 to $27,255 (p < 0.001). ED visits declined 19.9% (p < 0.001) and inpatient hospitalizations 40.9% (p < 0.001). Reductions were significant across all four baseline cost quartiles. Baseline TCOC was the dominant predictor of postenrollment costs (β = 0.50; p < 0.001; R2 = 0.23). At $100 per member per month, estimated net savings were $6.47 million (ROI: 9.0:1). CONCLUSION:Short-term RPM participation was associated with substantial reductions in TCOC and acute utilization among high-acuity Medicare beneficiaries, supporting RPM as a viable intervention to advance this population toward value-based care models. Prospective controlled evaluation is warranted to establish causal attribution.

Objective To examine food insecurity resource navigation program costs and how navigation intensity relates to clinical outcomes, healthcare costs, and quality of life (QOL) for diabetes and/or hypertension patients. Methods This retrospective study included patients receiving resource navigation (July 12, 2021-December 31, 2022 with twelve-month follow-up) across three primary care practices in South Carolina's largest health system. Participants were 18+ years old (from electronic medical records/Epic), had food insecurity (from Hunger Vital Sign™), and diabetes and/or hypertension (from Epic registries). Matched controls came from food insecurity screening-only practices. Patients in each group (n = 219) had diabetes (9.13%), hypertension (50.23%), or both (40.64%). Navigation, fixed resources, and training costs were estimated using micro-costing from a US hospital system perspective (2025 USD). Multivariable models examined associations between outcomes (HbA1c, blood pressure, body mass index, primary, emergency, and inpatient charges, QOL), and navigation frequency, and duration, controlling for age, gender, race/ethnicity, payer, and comorbidities. Results Program costs (total = $29,752.91) primarily included case reviews ($19,809.25), navigation ($5,068.67), and training ($1,975.84), averaging $135.86 per patient. Navigation intensity was associated with twelve-month changes in HbA1c, BMI, QOL, primary, and inpatient charges. Conclusions Navigation programs incur significant personnel time costs. Individuals with great healthcare needs may require intensive navigation.

ObjectivesCompare the prevalence of serious bacterial infections (SBI; urinary tract infection (UTI), bacteremia, and/or meningitis) and invasive bacterial infections (IBI; bacteremia and/or meningitis) among hypothermic infants with positive versus negative respiratory pathogen testing.Study DesignWe conducted a multicenter retrospective cohort study of infants ≤90 days presenting to an emergency department or directly admitted to a hospital from September 1, 2016 to May 5, 2021 with reported or documented hypothermia (≤36oC). Positive respiratory pathogen testing included positive single or multiplex nucleic acid amplification testing. The primary outcome was prevalence of SBI, defined as positive blood, urine, and/or cerebrospinal fluid culture and antibiotic treatment course; SBI and IBI prevalence were compared between infants with positive versus negative respiratory pathogen tests using chi-square test.ResultsRespiratory pathogen testing was obtained in 40.6% (446/1098) of hypothermic infants; of those, 24.9% (111/446) had a positive respiratory pathogen result. Infants with a positive respiratory pathogen result were more often older, ill-appearing at presentation, and evaluated during fall/winter months. The prevalence of SBI in our cohort was 7.4%, and the prevalence of IBI was 4.5%. There were no associations between respiratory pathogen test result and SBI or IBI.ConclusionsThe majority of young infants with hypothermia evaluated did not have respiratory pathogen testing performed. The diagnosis of SBI or IBI was not associated with a positive respiratory pathogen test. Further research is needed to understand the utility of respiratory pathogen testing in risk stratification for hypothermic infants.

Background: Proton-pump inhibitor (PPI) use for management of gastroesophageal reflux disease (GERD) consists of a short-duration trial, according to guidelines. Long-term usage is appropriate under certain indications. Literature has increasingly documented an adverse effect profile of PPIs, including kidney disease and bone fragility. Objective: To investigate the rate of occurrence of osteopenia, osteoporosis, and chronic kidney disease (CKD) in patients using PPI therapy for longer than the recommended trial period of 8 weeks. Methods: Retrospective cohort analysis of a single-site primary care clinic. Patients aged 18 to 65 years with PPI prescriptions longer than 8 weeks were included. Information regarding PPI prescriptions, demographics, and medical diagnoses was collected. Results: The search discovered 293 PPI-users and 1908 never-PPI-users. Demographics varied, with a P-value <0.05 in age, body mass index (BMI), and black population (higher in PPI group). The PPI cohort featured higher rates of osteoporosis/osteopenia and CKD ( P < 0.001). The odds ratios (ORs) of diagnosis with PPI use was 2.91 (95% CI = [1.692, 4.979]) in osteoporosis/osteopenia. The OR was 1.14 (95% CI = [1.141, 2.229]) in CKD and PPI use but higher with diabetes, elevated BMI, black race, and male gender. Conclusions and Relevance: We observed increased occurrence rates of osteoporosis, or osteopenia, and CKD in patients with prolonged PPI use. Demographics varied in age, BMI, and black race proportion. A logistic regression revealed increased likelihood of kidney disease and osteoporosis/osteopenia in association with PPI use. These results add to the evidence regarding long-term PPI use and the development of these conditions, but additional studies are needed.

Background:Treating hepatitis C virus (HCV) in people who inject drugs (PWID) has been associated with increased health-related quality of life (HRQOL). Polysubstance use (PSU) is common among PWID, but no studies have investigated PSU influence on PWID's HRQOL HCV treatment. Methods:Participants included 150 PWID receiving HCV treatment at opioid agonist treatment clinics in Bronx, NY. The EQ-5D-3L measurement tool assessed five health dimensions producing an index of HRQOL measured at baseline, 4-, 8-, and 12-weeks during treatment and 12- and 24-weeks post-treatment. PSU was determined at baseline. Generalized estimating equations assessed the influence of baseline PSU on changes in mean EQ-5D-3L index over time. Results:Of the 150 participants, 46 (30.7%) reported PSU and mean HRQOL overall was 0.655, indicating moderate HRQOL. Mean HRQOL was lower at all time-points for the PSU group compared to the non-PSU group. Though PSU group showed improvements in mean HRQOL from baseline (0.614) to 4-, 12- and follow-up week 24 (0.765, 0.768, and 0.731, respectively), the mean change of HRQOL scores was not significantly associated with PSU (p-value=0.956). Conclusions:For individuals with PWID, our study showed no difference in HRQOL between those who did and did not engage in PSU following HCV treatment.

Robotic retromuscular ventral hernia repair (rRMVHR) potentially combines the best features of open and minimally invasive VHR: myofascial release with abdominal wall reconstruction (AWR) with the lower wound morbidity of laparoscopic VHR. Proliferation of this technique has outpaced the data supporting this claim. We report 2-year outcomes of the first randomized controlled trial of oRMVHR vs rRMVHR. Single-center randomized control trial of open vs rRMVHR. 100 patients were randomized (50 open, 50 robotic). We included patients > 18 y/o with hernias 7–15 cm with at least one of the following: diabetes, chronic obstructive pulmonary disease (COPD), body mass index (BMI) ≥ 30, or current smokers. Primary outcome was occurrence of a composite outcome of surgical site infection (SSI), non-seroma surgical site occurrence (SSO), readmission, or hernia recurrence. Secondary outcomes were length of stay, any SSI or SSO, SSI/SSOPI, operative time, patient reported quality of life, and cost. Analysis was performed in an intention-to-treat fashion. Study was funded by a grant from Society of American Gastrointestinal and Endoscopic Surgeons. 90 patients were available for 30-day and 62 for 2-year analysis (rRMVHR = 46 and 32, oRMVHR = 44 and 30). Hernias in the open group were slightly larger (10 vs 8 cm, p = 0.024) and more likely to have prior mesh (36.4 vs 15.2

Hypertension (HTN) is a chronic condition that requires careful monitoring and management. Blood pressure readings in the clinic and self-reported blood pressure readings are often too intermittent to allow for careful management. Remote patient monitoring is a solution that may have positive impacts on HTN management. Individuals at cardiac and primary care clinics were prescribed a remote patient-monitoring (RPM) program. Patients were sent blood pressure monitors that were enabled to transmit data over cellular networks. We reviewed trends in HTN management retrospectively in patients who had previously been on conventional therapy for a year and participated in RPM for a minimum of 90 days. There were 6595 patients enrolled, and the mean duration on RPM was 289 days. A total of 4370 participants (66.3%) had uncontrolled HTN, and 2476 (37.5%) had stage 2 HTN. After at least 90 days on the RPM program, the number of patients with uncontrolled HTN reduced to 2648 (40.2%, p < 0.01), and the number of patients with stage 2 HTN reduced to 1261 (19.1%, p < 0.01). Systolic blood pressure improved by 7.3 mmHg for all patients and 16.7 mmHg for stage 2 HTN. There was improvement in mean arterial pressure (MAP) in all patients with uncontrolled HTN by 8.5 mmHg (p < 0.0001). RPM is associated with improved HTN control and provides further evidence supporting telehealth programs which can aid in chronic disease management.

Background: There is no evidence that insurance-mandated weight loss before bariatric surgery affects outcomes. Objective: This retrospective study evaluated the relationship between insurance-mandated weight management program (WMP) completion before primary bariatric surgery and postoperative outcomes. Setting: Suburban academic medical center. Methods: Patients who underwent laparoscopic Roux-en-Y gastric bypass (LRYGB, n = 572) or sleeve gastrectomy (SG, n = 484) from 2014 to 2019 were dichotomized to presence (LRYGB n = 431, SG n = 348) or absence (LRYGB n = 141, SG n = 136) of insurance-mandated WMP completion. Primary endpoints included follow-up rate, percent total weight loss (%TWL), and percent excess weight loss (%EWL) through 60 months after surgery. The Mann-Whitney U test compared between-group means with significance at P < .05. Results: Follow-up rate, %TWL, and %EWL were not different (P = NS) up to 60 months postoperation between groups for either surgery. Both LRYGB and SG patients without WMP completion maintained greater %TWL (LRYGB: 34.4 +/- 11.1% versus 29.8 +/- 11.0%, P = .159; SG: 21.4 +/- 10.0% versus 18.2 +/- 10.5%, P = .456) and %EWL (LRYGB: 71.3 +/- 26.3% versus 67.6 +/- 26.5%, P = .618; SG: 49.2 +/- 18.8% versus 47.5 +/- 28.8%, P = .753) at 36 months after surgery. Secondarily, duration of time to get to surgery was significantly greater among yes-WMP patients (LRYGB: 178 days versus 121 days, P < .001; SG: 169 days versus 95 days, P < .001). Conclusion: Insurance-mandated WMP completion before bariatric surgery delays patient access to surgery without improving postoperative weight loss potential and must be abandoned.

Background The effect of skin closure technique on surgical site occurrences (SSO) after open abdominal wall reconstruction (AWR) with retromuscular polypropylene mesh placement is largely unknown. We hypothesize that layered subcuticular skin closure with cyanoacrylate skin adhesive is protective of surgical site infection compared to standard stapled closure. Methods A retrospective review utilizing the Abdominal Core Health Quality Collaborative (ACHQC) database of all patients at Prisma Health-Upstate. All patients with open abdominal wall reconstruction (AWR) of midline incisional hernia defects with retromuscular polypropylene mesh placement from January 2013 to February 2020 were included. Patient demographics, comorbidities, type of hernia repair with mesh location, method of skin closure, and SSOs were collected. Skin closure method was divided into two groups, reflecting a temporal change in practice: staples (historical control group) versus subcuticular suture with cyanoacrylate skin adhesive with/without polymer mesh tape (study group). Primary endpoint was SSI and SSO. Secondary endpoints were SSO or SSI requiring procedural intervention (SSOPI/SSIPI). Standard statistical methods were utilized. Results A total of 834 patients were analyzed, with 263 treated with stapled skin closure and 571 with subcuticular and adhesive closure. On univariate analysis, the incidence of SSI was significantly lower in the study group (11.8 vs 6.8%; p = 0.002), as was the need for SSIPI (11.8 vs 6.7%; p = 0.015). Rate of SSO was not significantly different between groups (28.1 vs 27.2%), but the rate of SSO requiring intervention was lower in the study group (14.1 vs 9.3%; p = 0.045). Conclusion Layered skin closure technique, including subcuticular closure and adhesive, may reduce the risk of surgical site infection after open AWR. A prospective randomized trial is planned to confirm these findings.

To investigate a potential role for galectins as biomarkers that enable diagnosis or prognostication of breast or non-small cell lung cancer, the serum levels of galectins -1, -3, -7, -8, and -9 of cancer patients determined by ELISA assays were compared to the mutation status of 50 known cancer-critical genes, which were determined using multiplex PCR in tumors of the same patients. Mutations in the KIT proto-oncogene, which codes for the c-Kit protein, a receptor tyrosine kinase, correlated with higher levels of galectins -1, -3, -8, and -9 in breast cancer patients and galectin-1 in non-small cell lung cancer patients. Mutations in the KIT gene were more likely found in brain metastases from both of these primary cancers. The most common KIT mutation in our panel was p.M541L, a missense mutation in the transmembrane domain of the c-Kit protein. These results demonstrate an association between KIT oncogenic signaling and elevated serum galectins in patients with metastatic disease. Changes in protein trafficking and the glycocalyx composition of cancer cells may explain the observed alterations in galectin expression. This study can be useful for the targeted selection of receptor tyrosine kinase and galectin inhibitor anti-cancer treatments.

The COVID-19 pandemic has strained healthcare systems in many parts of the United States. During the early months of the pandemic, there was substantial uncertainty about whether the large number of COVID-19 patients requiring hospitalization would exceed healthcare system capacity. This uncertainty created an urgent need to accurately predict the number of COVID-19 patients that would require inpatient and ventilator care at the local level. As the pandemic progressed, many healthcare systems relied on such predictions to prepare for COVID-19 surges and to make decisions regarding staffing, the discontinuation of elective procedures, and the amount of personal protective equipment (PPE) to purchase. In this work, we develop a Bayesian Susceptible-Infectious-Hospitalized-Ventilated-Recovered (SIHVR) model to predict the burden of COVID-19 at the healthcare system level. The Bayesian SIHVR model provides daily estimates of the number of new COVID-19 patients admitted to inpatient care, the total number of non-ventilated COVID-19 inpatients, and the total number of ventilated COVID-19 patients at the healthcare system level. The model also incorporates county-level data on the number of reported COVID-19 cases, and county-level social distancing metrics, making it locally customizable. The uncertainty in model predictions is quantified with 95% credible intervals. The Bayesian SIHVR model is validated with an extensive simulation study, and then applied to data from two regional healthcare systems in South Carolina. This model can be adapted for other healthcare systems to estimate local resource needs.

Background Direct aspiration thrombectomy techniques use large bore aspiration catheters for mechanical thrombectomy. Several aspiration catheters are now available. We report a bench top exploration of a novel beveled tip catheter and our experience in treating large vessel occlusions (LVOs) using next-generation aspiration catheters. Methods A retrospective analysis from a prospectively maintained database comparing the bevel shaped tip aspiration catheter versus non-beveled tip catheters was performed. Patient demographics, periprocedural metrics, and discharge and 90-day modified Rankin Scale (mRS) scores were collected. Patients were divided into two groups based on which aspiration catheter was used. Results Our data showed no significant difference in age, gender, IV tissue plasminogen activator administration, admission NIH Stroke Scale score, baseline mRS, or LVO location between the beveled tip and flat tip groups. With the beveled tip, Thrombolysis in Cerebral Infarction (TICI) 2C or better recanalization was more frequent overall (93.2% vs 74.2%, p=0.017), stent retriever usage was lower (9.1% vs 29%, p=0.024), and patients had lower mRS on discharge (median 3 vs 4, p<0.001) and at 90 days (median 2 vs 4, p=0.008). Conclusion Patients who underwent mechanical thrombectomy with the beveled tip catheter had a higher proportion of TICI 2C or better and had a significantly lower mRS score on discharge and at 90 days.

The American College of Obstetricians and Gynecologists recommends that women exercise throughout pregnancy unless they have a condition-related contraindication. This study's purpose was to determine if pregnant women perceive receiving exercise counseling by their providers with details of frequency, intensity, type, and time (FITT principle). Women in 2 postpartum care units of a large health care system were invited to complete a voluntary, anonymous survey regarding whether they received exercise counseling during their prenatal care. Survey results were descriptively reported, stratified by demographic variables, and analyzed using Fisher's exact tests. Of 224 postpartum women surveyed, 130 (58.0%) perceived receiving exercise counseling during pregnancy; 119 (91.5%) did not recall receiving counseling on exercise frequency. Though 165 (73.6%) exercised before becoming pregnant, 64 (38.8%) ceased exercise during pregnancy. Eighty-eight (39.3%) received advice from other sources/non-health care professionals. Privately insured women reported receiving exercise counseling at a higher rate (70.1%) than those on Medicaid (44.8%) or uninsured (40.0%; P = .004). A disproportionate number of pregnant women perceived not receiving adequate prenatal exercise counseling or received incomplete counseling. Women at a socioeconomic disadvantage may be vulnerable. As social determinants of health, structural barriers, and socioeconomic status likely contribute, women may benefit from more targeted inclusive and equitable messaging.

OBJECTIVES:Helicopter transport of trauma patients remains controversial. We examined the survival rates of patients undergoing helicopter versus ground transport to a Level 1 trauma center.METHODS:Retrospective analysis was performed on trauma patients treated between 2014 and 2017. Student's t-test was used to compare air versus ground transport times. A logistic regression was then used to examine the association of transportation type on survival controlling for demographics, mechanism of injury, transport time, field intubation, and injury severity.RESULTS:Of 3967 patients identified, 69.6% (2762) were male, and the average age was 40 years. Most patients suffered blunt injuries (86.8%, 3445), while the remaining had penetrating injuries (11.6%, 459) or burns (1.6%, 63). The majority of patients were transferred by ground (3449) with only 13% (518) transferred by air. Patients transported by air had increased Injury Severity Score (ISS) with a median of 17 (IQR 9-24) versus 9 (IQR 5-14), increased length of stay (LOS) at 6 days versus 3 (P < .001), and increased mortality at 12.6% vs 6.5% (P < .001). Patients transported by air arrived 16.6 ± 6.7 minutes faster compared with ground for the zip codes examined. When adjusting for the mechanism of injury, ISS, age, gender, intubation status, and transport time, air transport was associated with an increased likelihood of survival (odds ratio [OR] = 1.57, 95% CI = 1.06-2.40).CONCLUSION:In our analysis of 3967 patients, those transported by air had a significant improvement in the likelihood of survival compared with those transported by ground even when adjusting for both ISS and time.

Introduction Obesity is an epidemic in the United States, known to be associated with comorbidities. However, some data show that obesity may be a protective factor in some instances. The purpose of this study is to determine if there are differences in morbidity and mortality when comparing the obese and non-obese critically ill trauma patient populations. Materials and Methods This was a retrospective study conducted at Prisma Health Upstate in Greenville, South Carolina, an Adult Level 1 Trauma Center. Patients over the age of 18 years admitted due to trauma from February 6, 2016 to February 28, 2019 were included in this study. Burn patients were excluded. An online trauma database was used to obtain age, sex, body mass index, Glasgow coma score (GCS), injury severity score (ISS), revised trauma score (RTS), days on mechanical ventilation, hospital length of stay (LOS), and intensive care unit (ICU) LOS. Results There were 2365 critically ill trauma patients who met inclusion criteria for this study. 1570 patients were men (66.38%) and mean age was 53.2 ± 20.9. Of the patients, 2166 patients had blunt trauma (91.59%). Median GCS was 15 (interquartilerange [IQR]: 12, 15), median RTS was 12 (IQR: 11, 12), and median ISS was 17 (IQR: 9, 22). Obese critically ill trauma patients had significantly lower odds of mortality than nonobese (OR .686, CI 0.473-.977). Penetrating traumas (OR: 4.206, CI: 2.478, 6.990), increased ISS (OR: 1.095, CI: .473, 1.112), and increased age (OR: 1.036, CI: 1.038, 1.045) were associated with significantly increased odds of mortality. Discussion The obesity paradox is observed in the obese critically ill trauma patient population.

Data registries facilitate knowledge acquisition and quality improvement. ImageGuide is a registry developed by the American Society of Nuclear Cardiology collecting data since 2015, providing insight into current nuclear cardiology practice. HIPAA de-identified data on > 100 practice- and patient-related variables from 19 US practices were obtained from ImageGuide. Continuous variables are reported as the mean ± standard deviation; discrete variables are reported as N (%). Practices were from 12 states; 9520 studies were submitted. The average patient was a 66-year-old man. Chest pain was the most common indication; 96% of studies were appropriate. Rest/stress 1-day studies were most common; stress/rest 1- and 2-day studies comprised < 5%. Tc-99 m was the most common radiopharmaceutical. Tl-201 was used in 14% of rest studies. Most studies were not corrected for attenuation. 89% were of good or better quality. 62% of studies were normal. Practice diversity is limited, but patient demographics are reflective of reported current practice. Most studies are appropriate and may obviate the need for invasive testing. Radiation dosimetry could be decreased with wider adoption of stress/rest studies and avoidance of Tl-201. ImageGuide will be an important tool to guide non-invasive cardiac imaging in the future.

OBJECTIVETo determine the association between the physical activity vital sign (PAVS) and markers of cardiometabolic disease.DESIGNPatients were assessed through the PAVS, a validated tool self-reporting the frequency and duration of physical activity. Patients were categorized into 3 groups: inactive (0 minutes per week), underactive (1-149 minutes per week), and active (>150 minutes per week). Associations were tested between the PAVS and the cardiometabolic disease biomarkers of body mass index, hemoglobin A1c (A1c), blood pressure, and low-density lipoprotein (LDL) using one-way analyses of variance.SETTINGHigh-risk family medicine residency clinic.PARTICIPANTSTwo thousand three hundred twenty-one adult patients (age ≥ 18 years).RESULTSParticipants reported a mean of 97.87 (SD = 149.35) minutes per week of exercise. Overall, 50.1% reported physical inactivity, 25.7% were underactive, and 24.3% were active. Younger individuals (P < 0.001) and men (P < 0.05) reported more physical activity than older individuals and women. Patients who reported being active were significantly less likely to be overweight (P < 0.05), obese (P < 0.05), or hypertensive (P < 0.05), but there was no association with A1c or LDL levels.CONCLUSIONSThis is the first investigation to examine the PAVS in a high-risk population. In these patients, reported levels of physical inactivity are 150% higher than other clinical settings, and the PAVS is only associated with improvements in 2 of 4 major cardiometabolic risk factors. For this group, self-reported levels of physical activity may need to be higher for cardiovascular benefits to be realized in all 4 cardiometabolic domains. The PAVS offers health professionals an opportunity to encourage lifestyle-based interventions to reduce cardiovascular risk, but refinements may be necessary to address this population.
