Item Open Access 2023 HRS/EHRA/APHRS/LAHRS Expert Consensus Statement on Practical Management of the Remote Device Clinic.(Europace : European pacing, arrhythmias, and cardiac electrophysiology : journal of the working groups on cardiac pacing, arrhythmias, and cardiac cellular electrophysiology of the European Society of Cardiology, 2023-05) Ferrick, Aileen M; Raj, Satish R; Deneke, Thomas; Kojodjojo, Pipin; Lopez-Cabanillas, Nestor; Abe, Haruhiko; Boveda, Serge; Chew, Derek S; Choi, Jong-Il; Dagres, Nikolaos; Dalal, Aarti S; Dechert, Brynn E; Frazier-Mills, Camille G; Gilbert, Olivia; Han, Janet K; Hewit, Sherri; Kneeland, Christine; Mirza, Starr DeEllen; Mittal, Suneet; Ricci, Renato Pietro; Runte, Mary; Sinclair, Susan; Alkmim-Teixeira, Ricardo; Vandenberk, Bert; Varma, Niraj; Davenport, Elizabeth; Freedenberg, Vicki; Glotzer, Taya V; Huang, Jin-Long; Ikeda, Takanori; Kramer, Daniel B; Lin, David; Rojel-Martínez, Ulises; Stühlinger, Markus; Varosy, Paul DRemote monitoring is beneficial for the management of patients with cardiovascular implantable electronic devices by impacting morbidity and mortality. With increasing numbers of patients using remote monitoring, keeping up with higher volume of remote monitoring transmissions creates challenges for device clinic staff. This international multidisciplinary document is intended to guide cardiac electrophysiologists, allied professionals, and hospital administrators in managing remote monitoring clinics. This includes guidance for remote monitoring clinic staffing, appropriate clinic workflows, patient education, and alert management. This expert consensus statement also addresses other topics such as communication of transmission results, use of third-party resources, manufacturer responsibilities, and programming concerns. The goal is to provide evidence-based recommendations impacting all aspects of remote monitoring services. Gaps in current knowledge and guidance for future research directions are also identified.Item Open Access Differences between chest pain observation service patients and admitted "rule-out myocardial infarction" patients.(Academic emergency medicine : official journal of the Society for Academic Emergency Medicine, 1997-07) Dallara, J; Severance, HW; Davis, B; Schulz, GObjective
To compare and contrast the patient characteristics of ED patients at low risk for acute cardiac ischemia who were assigned to a chest pain observation service vs those admitted to a monitored inpatient bed for "rule-out acute myocardial infarction" (R/O MI).Methods
This was a retrospective, cross-sectional comparison of adult patients considered at relatively low risk for cardiac ischemia and who were evaluated in 1 of 2 settings: a short-term observation service and an inpatient monitored bed. All patients had an ED final diagnosis of "chest pain," "R/O MI," or "unstable angina" during the 7-month study period. Demographic features and presenting clinical features were examined as a function of site of patient evaluation.Results
Of 531 study patients, 265 (50%) were assigned to the observation service. Younger age (OR = 1.75, 95% CI 1.26, 2.44, for each decrement of 20 years), the complaint of "chest pain" (OR = 2.35, 95% CI 1.34, 4.12), and the absence of prior known coronary artery disease (OR = 1.64, 95% CI 1.13, 2.38) were the principal independent factors associated with assignment to a chest pain observation service bed.Conclusions
Patients evaluated in a chest pain observation service appear to have different clinical characteristics than other individuals admitted to a monitored inpatient bed for "R/O MI." Investigators should address differences in clinical characteristics when making outcome comparisons between these 2 patient groups.Item Open Access Enhanced Recovery After Surgery (ERAS) for gastrointestinal surgery, part 2: consensus statement for anaesthesia practice.(Acta anaesthesiologica Scandinavica, 2016-03) Feldheiser, A; Aziz, O; Baldini, G; Cox, BPBW; Fearon, KCH; Feldman, LS; Gan, TJ; Kennedy, RH; Ljungqvist, O; Lobo, DN; Miller, T; Radtke, FF; Ruiz Garces, T; Schricker, T; Scott, MJ; Thacker, JK; Ytrebø, LM; Carli, FThe present interdisciplinary consensus review proposes clinical considerations and recommendations for anaesthetic practice in patients undergoing gastrointestinal surgery with an Enhanced Recovery after Surgery (ERAS) programme.Studies were selected with particular attention being paid to meta-analyses, randomized controlled trials and large prospective cohort studies. For each item of the perioperative treatment pathway, available English-language literature was examined and reviewed. The group reached a consensus recommendation after critical appraisal of the literature.This consensus statement demonstrates that anaesthesiologists control several preoperative, intraoperative and postoperative ERAS elements. Further research is needed to verify the strength of these recommendations.Based on the evidence available for each element of perioperative care pathways, the Enhanced Recovery After Surgery (ERAS®) Society presents a comprehensive consensus review, clinical considerations and recommendations for anaesthesia care in patients undergoing gastrointestinal surgery within an ERAS programme. This unified protocol facilitates involvement of anaesthesiologists in the implementation of the ERAS programmes and allows for comparison between centres and it eventually might facilitate the design of multi-institutional prospective and adequately powered randomized trials.Item Open Access Genome-wide association study of perioperative myocardial infarction after coronary artery bypass surgery.(BMJ Open, 2015-05-06) Kertai, Miklos D; Li, Yi-Ju; Li, Yen-Wei; Ji, Yunqi; Alexander, John; Newman, Mark F; Smith, Peter K; Joseph, Diane; Mathew, Joseph P; Podgoreanu, Mihai V; Duke Perioperative Genetics and Safety Outcomes (PEGASUS) Investigative TeamOBJECTIVES: Identification of patient subpopulations susceptible to develop myocardial infarction (MI) or, conversely, those displaying either intrinsic cardioprotective phenotypes or highly responsive to protective interventions remain high-priority knowledge gaps. We sought to identify novel common genetic variants associated with perioperative MI in patients undergoing coronary artery bypass grafting using genome-wide association methodology. SETTING: 107 secondary and tertiary cardiac surgery centres across the USA. PARTICIPANTS: We conducted a stage I genome-wide association study (GWAS) in 1433 ethnically diverse patients of both genders (112 cases/1321 controls) from the Genetics of Myocardial Adverse Outcomes and Graft Failure (GeneMAGIC) study, and a stage II analysis in an expanded population of 2055 patients (225 cases/1830 controls) combined from the GeneMAGIC and Duke Perioperative Genetics and Safety Outcomes (PEGASUS) studies. Patients undergoing primary non-emergent coronary bypass grafting were included. PRIMARY AND SECONDARY OUTCOME MEASURES: The primary outcome variable was perioperative MI, defined as creatine kinase MB isoenzyme (CK-MB) values ≥10× upper limit of normal during the first postoperative day, and not attributable to preoperative MI. Secondary outcomes included postoperative CK-MB as a quantitative trait, or a dichotomised phenotype based on extreme quartiles of the CK-MB distribution. RESULTS: Following quality control and adjustment for clinical covariates, we identified 521 single nucleotide polymorphisms in the stage I GWAS analysis. Among these, 8 common variants in 3 genes or intergenic regions met p<10(-5) in stage II. A secondary analysis using CK-MB as a quantitative trait (minimum p=1.26×10(-3) for rs609418), or a dichotomised phenotype based on extreme CK-MB values (minimum p=7.72×10(-6) for rs4834703) supported these findings. Pathway analysis revealed that genes harbouring top-scoring variants cluster in pathways of biological relevance to extracellular matrix remodelling, endoplasmic reticulum-to-Golgi transport and inflammation. CONCLUSIONS: Using a two-stage GWAS and pathway analysis, we identified and prioritised several potential susceptibility loci for perioperative MI.Item Open Access Glucose control in hospitalized patients.(American family physician, 2010-05) Sawin, Gregory; Shaughnessy, Allen FEvidence indicates that hospitalized patients with hyperglycemia do not benefit from tight blood glucose control. Maintaining a blood glucose level of less than 180 mg per dL (9.99 mmol per L) will minimize symptoms of hyperglycemia and hypoglycemia without adversely affecting patient-oriented health outcomes. In the absence of modifying factors, physicians should continue patients' at-home diabetes mellitus medications and randomly check glucose levels once daily. Sulfonylureas should be withheld to avoid hypoglycemia in patients with limited caloric intake. Patients with cardiovascular conditions may benefit from temporarily stopping treatment with thiazolidinediones to avoid precipitating heart failure. Metformin should be temporarily withheld in patients who have worsening renal function or who will undergo an imaging study that uses contrast. When patients need to be treated with insulin in the short term, using a long-acting basal insulin combined with a short-acting insulin before meals (with the goal of keeping blood glucose less than 180 mg per dL) better approximates normal physiology and uses fewer nursing resources than sliding-scale insulin approaches. Most studies have found that infusion with glucose, insulin, and potassium does not improve mortality in patients with acute myocardial infarction. Patients admitted with acute myocardial infarction should have moderate control of blood glucose using home regimens or basal insulin with correctional doses.Item Open Access How can innovative uses of technology be harnessed to improve medication adherence?(Expert review of pharmacoeconomics & outcomes research, 2012-04) Bosworth, Hayden BItem Open Access Mobile health devices: will patients actually use them?(Journal of the American Medical Informatics Association : JAMIA, 2016-05) Shaw, Ryan J; Steinberg, Dori M; Bonnet, Jonathan; Modarai, Farhad; George, Aaron; Cunningham, Traven; Mason, Markedia; Shahsahebi, Mohammad; Grambow, Steven C; Bennett, Gary G; Bosworth, Hayden BAlthough mobile health (mHealth) devices offer a unique opportunity to capture patient health data remotely, it is unclear whether patients will consistently use multiple devices simultaneously and/or if chronic disease affects adherence. Three healthy and three chronically ill participants were recruited to provide data on 11 health indicators via four devices and a diet app. The healthy participants averaged overall weekly use of 76%, compared to 16% for those with chronic illnesses. Device adherence declined across all participants during the study. Patients with chronic illnesses, with arguably the most to benefit from advanced (or increased) monitoring, may be less likely to adopt and use these devices compared to healthy individuals. Results suggest device fatigue may be a significant problem. Use of mobile technologies may have the potential to transform care delivery across populations and within individuals over time. However, devices may need to be tailored to meet the specific patient needs.Item Open Access Poor adoption of hemodynamic optimization during major surgery: are we practicing substandard care?(Anesth Analg, 2011-06) Miller, Timothy E; Roche, Anthony M; Gan, Tong JItem Open Access Tissue-Integrating Oxygen Sensors: Continuous Tracking of Tissue Hypoxia.(Advances in experimental medicine and biology, 2017-01) Wisniewski, Natalie A; Nichols, Scott P; Gamsey, Soya J; Pullins, Steve; Au-Yeung, Kit Y; Klitzman, Bruce; Helton, Kristen LWe describe a simple method of tracking oxygen in real-time with injectable, tissue-integrating microsensors. The sensors are small (500 μm × 500 μm × 5 mm), soft, flexible, tissue-like, biocompatible hydrogel s that have been shown to overcome the foreign body response for long-term sensing. The sensors are engineered to change luminescence in the presence of oxygen or other analytes and function for months to years in the body. A single injection followed by non-invasive monitoring with a hand-held or wearable Bluetooth optical reader enables intermittent or continuous measurements. Proof of concept for applications in high altitude, exercise physiology, vascular disease, stroke, tumors, and other disease states have been shown in mouse, rat and porcine models. Over 90 sensors have been studied to date in humans. These novel tissue-integrating sensors yield real-time insights in tissue oxygen fluctuations for research and clinical applications.Item Open Access Utilization of Brain Tissue Oxygenation Monitoring and Association with Mortality Following Severe Traumatic Brain Injury.(Neurocritical care, 2022-04) Komisarow, Jordan M; Toro, Camilo; Curley, Jonathan; Mills, Brianna; Cho, Christopher; Simo, Georges Motchoffo; Vavilala, Monica S; Laskowitz, Daniel T; James, Michael L; Mathew, Joseph P; Hernandez, Adrian; Sampson, John; Ohnuma, Tetsu; Krishnamoorthy, VijayBackground
The aim of this study was to describe the utilization patterns of brain tissue oxygen (PbtO2) monitoring following severe traumatic brain injury (TBI) and determine associations with mortality, health care use, and pulmonary toxicity.Methods
We conducted a retrospective cohort study of patients from United States trauma centers participating in the American College of Surgeons National Trauma Databank between 2008 and 2016. We examined patients with severe TBI (defined by admission Glasgow Coma Scale score ≤ 8) over the age of 18 years who survived more than 24 h from admission and required intracranial pressure (ICP) monitoring. The primary exposure was PbtO2 monitor placement. The primary outcome was hospital mortality, defined as death during the hospitalization or discharge to hospice. Secondary outcomes were examined to determine the association of PbtO2 monitoring with health care use and pulmonary toxicity and included the following: (1) intensive care unit length of stay, (2) hospital length of stay, and (3) development of acute respiratory distress syndrome (ARDS). Regression analysis was used to assess differences in outcomes between patients exposed to PbtO2 monitor placement and those without exposure by using propensity weighting to address selection bias due to the nonrandom allocation of treatment groups and patient dropout.Results
A total of 35,501 patients underwent placement of an ICP monitor. There were 1,346 (3.8%) patients who also underwent PbtO2 monitor placement, with significant variation regarding calendar year and hospital. Patients who underwent placement of a PbtO2 monitor had a crude in-hospital mortality of 31.1%, compared with 33.5% in patients who only underwent placement of an ICP monitor (adjusted risk ratio 0.84, 95% confidence interval 0.76-0.93). The development of the ARDS was comparable between patients who underwent placement of a PbtO2 monitor and patients who only underwent placement of an ICP monitor (9.2% vs. 9.8%, adjusted risk ratio 0.89, 95% confidence interval 0.73-1.09).Conclusions
PbtO2 monitor utilization varied widely throughout the study period by calendar year and hospital. PbtO2 monitoring in addition to ICP monitoring, compared with ICP monitoring alone, was associated with a decreased in-hospital mortality, a longer length of stay, and a similar risk of ARDS. These findings provide further guidance for clinicians caring for patients with severe TBI while awaiting completion of further randomized controlled trials.Item Open Access Variation in use of surveillance colonoscopy among colorectal cancer survivors in the United States.(BMC Health Serv Res, 2010-09-01) Salz, Talya; Weinberger, Morris; Ayanian, John Z; Brewer, Noel T; Earle, Craig C; Elston Lafata, Jennifer; Fisher, Deborah A; Weiner, Bryan J; Sandler, Robert SBACKGROUND: Clinical practice guidelines recommend colonoscopies at regular intervals for colorectal cancer (CRC) survivors. Using data from a large, multi-regional, population-based cohort, we describe the rate of surveillance colonoscopy and its association with geographic, sociodemographic, clinical, and health services characteristics. METHODS: We studied CRC survivors enrolled in the Cancer Care Outcomes Research and Surveillance (CanCORS) study. Eligible survivors were diagnosed between 2003 and 2005, had curative surgery for CRC, and were alive without recurrences 14 months after surgery with curative intent. Data came from patient interviews and medical record abstraction. We used a multivariate logit model to identify predictors of colonoscopy use. RESULTS: Despite guidelines recommending surveillance, only 49% of the 1423 eligible survivors received a colonoscopy within 14 months after surgery. We observed large regional differences (38% to 57%) across regions. Survivors who received screening colonoscopy were more likely to: have colon cancer than rectal cancer (OR = 1.41, 95% CI: 1.05-1.90); have visited a primary care physician (OR = 1.44, 95% CI: 1.14-1.82); and received adjuvant chemotherapy (OR = 1.75, 95% CI: 1.27-2.41). Compared to survivors with no comorbidities, survivors with moderate or severe comorbidities were less likely to receive surveillance colonoscopy (OR = 0.69, 95% CI: 0.49-0.98 and OR = 0.44, 95% CI: 0.29-0.66, respectively). CONCLUSIONS: Despite guidelines, more than half of CRC survivors did not receive surveillance colonoscopy within 14 months of surgery, with substantial variation by site of care. The association of primary care visits and adjuvant chemotherapy use suggests that access to care following surgery affects cancer surveillance.
