Telemedicine: Technology versus the business case

Summary. The implementation of telemedicine is spreading throughout the government and commercial sectors. Telemedicine is being implemented in an effort to contain costs and capture all medically related business in a given catchment area. Telemedicine and off-the-shelf DICOM teleradiology systems can allow for patient images and demographic data to be transmitted electronically over telecommunications lines from satellite clinics to medical centres. The technology allows virtual centres of excellence to be extended to the medical community which provide the expertise and training of physicians to remote sites, while realizing cost savings. The technology to implement telemedicine is available today but it can be very costly if the business case for the system is not carefully evaluated and executed. The decision to implement a telemedicine system must be based upon the business case which supports expenditures by realizing cost savings through prudent selection of technology and medical business practices.     

Telemedicine use among burn centers in the United States: a survey

Telemedicine has been increasingly used in a host of settings for over 20 years. Burns are well suited for evaluation by either synchronous ("interactive") video or asynchronous digital ("store and forward") imagery, but little information is available about telemedicine use in burn care. The authors surveyed U.S. burn center directors to assess their current use of, and interest in, telemedicine in clinical burn treatment. With Institutional Review Board approval, a web-based survey (surveymonkey.com) was created and sent to directors of 126 burn centers in the United States. Questions measured the use of telemedicine by burn centers and burn directors' attitudes toward telemedicine. Surveys were returned from 50 centers (40%). Directors of 42 units (84%) reported using telemedicine; 37 use it routinely. Interactive video communication was used by 18 centers, store and forward by 38 centers, and remote access to patient data by home computer or personal digital assistant in 41 centers. Uses included remote evaluation of acute burns for consultation, for help in determining the need for transfer, or for remote clinic follow-up. Users identified some problems with current telemedicine usage, including Health Insurance Portability and Accountability Act/compliance, licensure, and billing/collection issues. Importantly, 40 respondents (80%) indicated that they would like programming on telemedicine to be available at American Burn Association's annual meetings. Use of telemedicine is fairly widespread among U.S. burn centers, with volume and type of usage varying widely. Significant interest in learning more about telemedicine suggests strongly that telemedicine should be included in the annual program at the American Burn Association.     

ICU telemedicine. Organization and communication

Telemedicine offers off-site physicians the ability to care for patients by providing them with audio-video links and access to relevant clinical data. Traditionally, this care modality has been used to overcome geographic barriers by bringing needed expertise to patients in remote locations. The same technology can be used to bring intensivist expertise to ICU patients. A recent clinical trial has confirmed the efficacy of remote ICU care, with decreases in mortality, complications, and costs that are analogous to those observed with on-site intensivists. If a single, intensivist-led care team can provide round-the-clock, proactive care to patients in multiple ICUs simultaneously, this care modality can be used to overcome current deficiencies in ICU care related to inadequate intensivist availability.     

Telemedicine follow-up of burns: lessons learned from the first thousand visits

Telemedicine is an evolving technology that is used for health education, health care administration, and health care distribution. The potential benefits of telemedicine include a decrease in travel expenses, improved continuity of care, and increased access to specialized consultants, thus meeting the needs of patients, practitioners, and communities. Telemedicine has many evolving applications, including improved access to health care in medically underserved and rural areas. Regions Burn Center assessed the efficacy and efficiency of burn visits via telemedicine and identified the barriers and benefits specific to burn care. Information regarding travel costs and financial data were evaluated from a total of 1000 burn follow-up visits with 294 patients via telemedicine during a 5-year interval. Our results indicate that telemedicine burn visits are a cost-effective clinical alternative for the patient. However, telemedicine can be a financial burden to health care systems and inefficient for health care providers.     

Accuracy and Clinical Utility of Transtelephonic Pacemaker Follow-Up

The diagnostic accuracy of transtelephonic pacemaker monitoring (TTM) has been quantified in a retrospective study involving 369 patients in three U.S. cardiac centers. Using existing medical records, TTM findings in a total of 413 reports were judged for equivalence to the findings of subsequent physical examinations in pacemaker clinics. This study found TTM follow-up testing to have a sensitivity of 94.6%, specificity of 98.5%, positive predictive value of 93.3%, and negative predictive value of 98.8%. The study also documents the clinical utility of TTM in identifying various modes of pacemaker malfunctions and instances of significant arrhythmia.     

Evaluation of Missed Diagnoses for Patients Admitted from the Emergency Department

OBJECTIVE: To define a quality assurance instrument to evaluate errors in diagnostic processes made by physicians in the emergency department (ED). METHODS: This was a retrospective clinical investigation of inpatient ED records. Over a six-year period, 5,000 medical records of admitted patients were randomly selected for evaluation. Each record was initially examined by one of five physician evaluators. If the primary ED diagnosis differed from the primary discharge diagnosis, the ED record was inspected to determine reasons for the misdiagnosis. The authors considered several aspects of the diagnostic process, including patient history, tests ordered, interpretation of clinical data, choice and performance of procedures, injury pattern recognition, reasoning, and evaluation. Records that demonstrated errors in the diagnostic process were reevaluated for the same diagnostic process errors by a sixth physician. Disagreements regarding suspected errors in the diagnostic process were settled by discussion. Finally, to determine potential medical consequences of the misdiagnosis, one individual reviewed the complete medical records of patients whose ED medical records were scored with errors by both evaluators. Interevaluator reliability was assessed using Cochran's Q-test with a selected series of medical records. RESULTS: Twenty-eight records (0.6%) were found to contain one or more errors in the diagnostic process that contributed to misdiagnosis. For these patients appropriate diagnosis was not made until one to 16 days after admission. Three patients of 18 whose records were available for detailed review may have suffered complications that resulted, in part, from the delay in diagnosis and subsequent treatment. Significant interevaluator reliability for identification of errors in the diagnostic process was obtained (p > 0.1). CONCLUSIONS: A two-tiered evaluation of ED records selected by inconsistent initial and final diagnoses can be used reliably to screen for errors in the diagnostic process made by emergency physicians (EPs). The rate of physician error contributing to a misdiagnosis is very low, suggesting that EPs are delivering quality patient care.     

Anesthesiologist and chronic pain

Effective therapy of chronic frequently recurring pain is a complex important problem from practical medical, social, and economic viewpoints. Organization of specialized "pain clinics" and pain control centers is discussed. These institutions will take care of patients with chronic pain syndromes. The role of anesthesiologists and reanimatologists at such clinics is analyzed. Experience gained at department of therapy of painful syndromes at the Russian Center of Surgery of the Russian Academy of Medical Sciences and the Integrative Medicine Center attached to it is reviewed. The authors offer recommendations on the use of traditional and nontraditional methods of pain relief. New highly effective integrative diagnostic methods (computer pulsometry) and therapies (resonance electropuncture analgesia and therapy) are used in various pain syndromes, including chronic frequently relapsing, which are usually resistant to common methods. Integrative methods of clinical reflex therapy create conditions for replacing traumatic surgical and radiological methods used in the treatment of critically ill patients by methods of integrative medicine.     

Use of a validated delirium assessment tool improves the ability of physicians to identify delirium in medical intensive care unit patients

OBJECTIVE: Although medical intensive care unit nurses at our institution routinely use the Intensive Care Delirium Screening Checklist (ICDSC) to identify delirium, physicians rely on traditional diagnostic methods. We sought to measure the effect of physicians' use of the ICDSC on their ability to detect delirium. DESIGN: Before-after study. SETTING: Medical intensive care unit of an academic medical center. PATIENTS AND PARTICIPANTS: A total of 25 physicians with >or=1 month of clinical experience in the medical intensive care unit conducted 300 delirium assessments in 100 medical intensive care unit patients. MEASUREMENTS AND MAIN RESULTS: Physicians sequentially evaluated two patients for delirium using whatever diagnostic method preferred. Following standardized education regarding ICDSC use, each physician evaluated two different patients for delirium using the ICDSC. Each physician assessment was preceded by consecutive, but independent, evaluations for delirium by the patient's nurse and then a validated judge using the ICDSC. Before (PRE) physician ICDSC use, the validated judge identified delirium in five patients; the physicians and nurses identified delirium in zero and four of these patients, respectively. The physicians incorrectly identified delirium in four additional patients. After (POST) physician ICDSC use, the validated judge identified delirium in 11 patients; the physicians and nurses identified delirium in eight and ten of these patients, respectively. The physicians incorrectly identified delirium in one patient. After physician ICDSC use, agreement improved between both the physicians and validated judge (PRE kappa = -0.14 [95% confidence interval {CI} = -0.27 to -0.02] to POST kappa = 0.67 [95% CI = 0.38 to 0.96]) and physicians and nurses (PRE kappa = -0.15 [95% CI = -0.29 to -0.02] to POST kappa = 0.58 [95% CI = 0.25 to 0.91]). Nurses vs. validated judge agreement was strong in both periods (PRE kappa = 0.65 [95% CI = 0.29 to 1.00] and POST kappa = 0.92 [95% CI = 0.76 to 1.00]). CONCLUSIONS: Use of the ICDSC, along with education supporting its use, improves the ability of physicians to detect delirium in the medical intensive care unit.     

Substance Use Disorder Treatment via Telemedicine During Coronavirus Disease 2019

Telemedicine has been effective at bridging the gap among patients, providers, and health systems. Authors from a large academic medical center in Baltimore, MD, anecdotally found that digital tools were beneficial in supporting substance use disorder recovery during a global pandemic. Audiovisual tools like Zoom (Zoom Video Communications, Inc, San Jose, CA) and Doximity (Doximity, Inc, San Francisco, CA), as well as increased frequency of communication with patients, have been most helpful to supporting recovery. The barriers noted were related to patient privacy and increased tendency of patients to avoid treatment, similar barriers as when treatment is provided in the clinic. The intent of this narrative is to discuss provider perspectives of benefits and barriers to telemedicine for substance use disorder treatment during the coronavirus disease 2019 pandemic.     

Telemedicine and the delivery of health services to veterans with multiple sclerosis

Telemedicine involves the provision of health care and sharing of medical knowledge using telecommunications technologies. Preventive, diagnostic, and therapeutic services, as well as patient education and assistance with self-management of health, can be provided via telemedicine. The Veterans Health Administration (VHA) has a wide range of telemedicine capabilities. Given limitations on studying its effectiveness, telemedicine is often applied to new patient populations without explicit evaluation of efficacy. Evaluating the potential use of telemedicine services through supporting literature from other disorders may be possible. This paper discusses applying telemedicine to the care of individuals with multiple sclerosis (MS) when few published evaluations exist in MS. In this paper, we (1) provide a background on the use of telemedicine in the private sector and in the VHA, (2) discuss the use of current telemedicine literature to management of individuals with MS, and (3) review the strengths and limitations of telemedicine as a care delivery vehicle.     

Knowledge Translation of the American College of Emergency Physicians Clinical Policy on Hypertension

Objectives To determine if dissemination of the American College of Emergency Physicians clinical policy on hypertension to emergency physicians would lead to improvements in blood pressure reassessment and referral of emergency department (ED) patients with elevated blood pressure.
Methods Two academic centers implemented a pre-post intervention design, with independent samples at pre and post phases. ED staff were blinded to the investigation. A total of 377 medical records were reviewed before policy dissemination and 402 were reviewed after policy dissemination. Medical records were eligible for review if the patient was at least 18 years of age, was not pregnant, was discharged from the ED, and had a triage systolic blood pressure ≥140 mm Hg or diastolic blood pressure ≥90 mm Hg. Patient records with a chief complaint of chest pain, shortness of breath, or neurologic complaints were excluded. Demographics, blood pressures, and evidence of discharge referral were abstracted from the medical record. The policy was disseminated after the initial medical record review. Post—policy dissemination medical record review was conducted within two weeks.
Results A total of 779 medical records were reviewed. The mean age of patients was 45 years, 55% were male, and 46% were white, 13% Hispanic, 35% African American, and 6% other. No differences in reassessment or referral rates were found between study phases. Blood pressure reassessments were low during both phases: 33% (pre) and 37% (post). Referral rates of patients with elevated blood pressure were very low: 13% (pre) and 7% (post).
Conclusions Knowledge of guidelines did not translate into changes in physician practice. Additional systems-based approaches are necessary to effectively translate guidelines into clinical practice.     

Unexpected death within 72?hours of emergency department visit: were those deaths preventable?

IntroductionWe aimed to determine the rate of preventable death in patients who died early and unexpectedly following hospital admission from the emergency department (ED).MethodsWe conducted a retrospective multicenter study in four centers from the Paris metropolitan area. Inclusion criteria were medical patients who died in hospital within 72 hours of ED attendance and were not admitted to the intensive care unit (unexpected death). Exclusion criteria were limitations of care determined by treating physicians. The existence of a limitation of care decision was adjudicated by two independent chart abstractors. Preventable death was defined as death occurring as a result of medical error. For each selected patient with unexpected death, charts were examined for medical errors and rated on a 1 to 5 preventability scale (from very unlikely to very likely) for the preventability of the death. The primary endpoint was the likely preventable death, rated as 4 or 5 on the preventability scale.ResultsWe retrieved 555 charts; 47 unexpected deaths were analysed; 24 (51%) were considered as preventable. There was a median number of medical errors of two. The most common process breakdowns were incorrect choice of treatment (47% of patients) and failure to order appropriate diagnostic tests (38% of patients). The most common medical error was a severe delay or absence of recommended treatment for severe sepsis, which occurred in 10 (42%) patients.ConclusionsIn our sample, more than half of unexpected deaths are related to a medical error, and could have been prevented.     

When cure is care: diagnosis and management of pulmonary arterial hypertension

PURPOSE: The purpose of this article is to provide nurse practitioners with an understanding of the pathophysiology of pulmonary arterial hypertension (PAH) disease, clinical manifestations, diagnostic evaluation, drug therapy, strategies for health promotion, and relevant care issues for patients and families. DATA SOURCES: Selected clinical and research articles, as well as current government guidelines. CONCLUSIONS: Symptoms expressed are more apparent as PAH disease progresses, leaving fewer treatment options in advanced disease stages. New drugs are currently being tested for the treatment of PAH; however, the costs of many of the currently approved treatments may be prohibitive. IMPLICATIONS FOR PRACTICE: Earlier recognition of disease symptoms leads to prompt initiation of diagnostic evaluation and referral to specializing medical centers. Upon referral, specialty centers may begin appropriate treatment regimens earlier in the disease process, which could improve clinical outcomes and quality of life.     

Medical Student Acquisition of Clinical Working Knowledge

Background: Working knowledge of physicians manifests as a combination of diagnostic pattern recognition and clinical data interpretation (analytic fact checking). Purpose: The purpose was to study medical student acquisition of these abilities as a function of years of medical training/experience. Methods: A cross-sectional study involving students who had completed 0, 1, 2, and 3 years of medical school. All students at all levels of training took the same tests of diagnostic pattern recognition and clinical data interpretation. Percent correct scores were calculated and used to estimate learning curves. A cohort of family physicians also took the test to provide a benchmark. Results: Student diagnostic pattern recognition and clinical data interpretation ability demonstrated a steady upward growth curve but leveled off in Year 3. Diagnostic pattern recognition performance was consistently higher than clinical data interpretation performance. The rate of diagnostic performance gain with training and experience was also higher. Conclusions: Medical students acquired diagnostic pattern recognition ability and all years of medical training contributed. The rate of clinical data interpretation performance improvement was slower, and the absolute performance level was lower. What was surprising was the lower rate of improvement in diagnostic pattern recognition and clinical data interpretation performance for students during their 1st year of clinical training. Students' understanding of findings and their relationships to disease processes may be affected by their limited patient experience.     

Personal, organizational, and market level influences on physicians' practice patterns: results of a national survey of primary care physicians

BACKGROUND: One of the principal tenets of managed care is that physicians' clinical decisions can be influenced both to improve the quality and consistency of care and to decrease health care expenditures. Medical decision making, however, remains a complex phenomenon and the most important determinants of physicians' approaches to clinical decision making remain poorly understood. OBJECTIVES: To determine how clinical decisions are associated with individual characteristics, practice setting and organizational characteristics, attributes of the patient population under care, and the market environment. RESEARCH DESIGN: Cross-sectional, nationally representative survey of patient-care physicians. SUBJECTS: Primary care physicians who provide direct patient care at least 20 hours per week. MEASURES: Proportion of physicians who would order a referral, diagnostic test, or treatment for 5 clinical scenarios thought to be representative of discretionary medical decisions. RESULTS: Responses were received from 4,825 primary care physicians who cared for adult patients (Response Rate 65%). The distribution of results for each of the five clinical scenarios demonstrates significant variability both within and between physicians. No evidence was seen of a consistent practice style across the vignettes (eg, "aggressive" or "conservative"). The organizational setting of practice was the most consistent predictor of behavior across all the clinical scenarios, with the exception of back pain, which was minimally related to any of the environmental factors. When compared to physicians in solo practice, physicians in all other practice settings were less likely to order a test or referral or pursue treatment. Practice involvement with managed care and measures of financial influences and administrative strategies associated with managed care were minimally and inconsistently associated with reported physician behaviors. CONCLUSIONS: The ability of managed care to improve the quality and consistency of care while also controlling the costs of care depends on its ability to influence medical decisions. Our findings generally demonstrate that managed care has a weak influence on discretionary medical decisions and that the influence of managed care pales in comparison to personal and practice setting influences.     

Feasibility of performing a virtual patient examination using three-dimensional ultrasonographic data acquired at remote locations.

OBJECTIVE: To evaluate the feasibility of performing three-dimensional ultrasonographic studies that meet American Institute of Ultrasound in Medicine and American College of Radiology ultrasonographic examination guidelines with review off-line and at remote locations. METHODS: One hundred patients were studied at 2 institutions using high-end two-dimensional clinical ultrasonographic scanners and commercially available three-dimensional ultrasonography for a variety of organ systems (first- and second-trimester fetus, abdomen, and female pelvis). We evaluated several parameters, including measurements, completeness of organ visualization, abnormalities identified, image quality, number of volumes required, and discrepancies between interpretations. RESULTS: Overall, three-dimensional ultrasonography could produce diagnostic-quality results comparable with those of two-dimensional ultrasonography. Three-dimensional ultrasonographic image quality was lower than that of two-dimensional ultrasonography. Two- and three-dimensional ultrasonographic measurements were comparable (<5% difference), as was the extent of organ visualization, although some structures were challenging for both two- and three-dimensional ultrasonography. In general, organs completely imaged in the scanner field of view required 1 to 1.5 volumes, whereas larger organs required between 3 and 6 volumes. Differences among reviewers' interpretations highlighted the need for standardization of acquisition and reviewing protocols for sonographers and physicians. CONCLUSIONS: Our results show that it is clinically feasible to acquire three-dimensional ultrasonographic data at one site and to obtain accurate interpretation by off-line review at another within the context of providing high-quality clinical diagnostic studies.     

Primary percutaneous coronary intervention in acute myocardial infarction

Primary percutaneous coronary intervention (PCI) has emerged as the preferred therapy for acute ST-segment elevation myocardial infarction (STEMI), as multiple randomized clinical trials and pooled analyses have shown improved clinical outcomes compared with medical reperfusion. Unfortunately, medical centers with 24-hour PCI capability are concentrated in urban areas, relegating many patients in the United States to inferior medical reperfusion. Ongoing substantial research efforts are directed at optimizing mechanical reperfusion, including refinements in adjuvant medical therapy and the use of drug-eluting stents in the catheterization laboratory. Research efforts are also focusing on the implementation of streamlined transfer systems from community centers to tertiary care centers, akin to systems used in the trauma model. Furthermore, experience with the performance of primary PCI at community centers without onsite surgical backup is growing. This article summarizes data regarding the current state, challenges, and future directions of primary PCI for STEMI, emphasizing adherence to current American College of Cardiology/American Heart Association guidelines.

Thermography.

As thermographic equipment is improved and as physicians gain experience in its use, thermography gradually is gaining importance as a diagnostic aid in a wide range of disease processes. The technic is finding increasing acceptance in diagnosis of breast disease particularly as an adjunct to mammography. The American Cancer Society and the National Cancer Institute are in the process of establishing 20 demonstration centers for breast cancer detection using thermography, mammography, and physical examinations. Although all of the centers are not at present fully staffed with personnel experienced in thermographic interpretation, the project promises to give a better basis for cost estimates for screening with the thermography as compared to present systems. The technologic knowledge exists for the development of improved scanning infrared cameras with magnetic tape storage and dynamic display. These systems will lend themselves to quantitative measurements and semiautomatic interpretation which can improve the accuracy and reduce the cost of mass screening for breast cancer. Although additional clinical research is necessary, thermography has numerous applications in a variety of disease states. In the future, total body thermography may well become an important part of medical screening examinations.
