Background: Physical therapists, as clinical human movement experts, must qualitatively evaluate patients' functional and biomechanical impairments. There are now low-cost 2- and 3-dimensional video measurement systems that can be used to increase the precision and reliability of these qualitative clinical assessments., Purpose: The purpose of this study was to systematically review current low-cost video-based methods for motion analysis compared with gold-standard 3-dimensional biomechanical methods., Data Sources: Electronic searches were conducted until January 2018 within the following databases: MEDLINE via PubMed, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Cochrane, Scopus, and the Institute of Electrical and Electronics Engineers., Study Selection: Studies designed to evaluate criterion-referenced validity and/or reliability of video-based motion analysis technologies within the last 20 years were included. English-language articles dealing with human rehabilitation were considered., Data Extraction: Data extraction was independently completed by 3 reviewers, and methodological quality was assessed using the 2018 Consensus-Based Standards for the Selection of Health Measurement Instruments checklist. Articles were organized for analysis on the basis of type of motion analyzed and category of each low-cost technology used., Data Synthesis: With 20 articles meeting selection criteria, 10 low-cost motion analysis platforms were presented, each examining different functional movement-dependent variables. Overall article quality was "low" or "very low" on the basis of Consensus-Based Standards for the Selection of Health Measurement Instruments scoring. Correlations between low-cost and 3-dimensional gold standard systems ranged widely from "poor" agreement (r = 0.025) to "strong" agreement (r = 0.992). Spatiotemporal gait parameters consistently outperformed planar joint angle data. Reliability was better measured than concurrent validity. A summary table was developed to assist clinicians in choosing which motions could potentially be measured accurately by each low-cost platform on the basis of current findings., Limitations: Databases available to researchers were more clinical/medical in nature, and this review was written from that clinically based perspective. Lack of standardized protocols and methodology within included studies was common, making generalizability difficult., Conclusions: Research attempting to validate newer low-cost movement analysis systems is limited in quality. Measurement of only certain variables should be considered when these tools are used. Further research is warranted, because these devices still have potential clinical utility for supplementing qualitative movement assessment with objective outcome measures., (© 2019 American Physical Therapy Association.)

Adolescents with severe eating disorders require hospitalization for medical stabilization. Supervision best practices for these patients are not established. This study sought to evaluate the cost and feasibility of centralized video monitoring (CVM) supervision on a general pediatric unit of an academic quaternary care center. This was a retrospective cohort study of nursing assistant (NA) versus CVM supervision for girls 12-18 years old admitted for medical stabilization of an eating disorder between September 2013 and March 2017. There were 37 consecutive admissions (NA = 23 and CVM = 14). NA median supervision cost was more expensive than CVM ($4,104/admission vs $1,166/admission, P < .001). Length of stay and days to weight gain were not statistically different. There were no occurances of family refusal of CVM, conversion from CVM to NA, technological failure, or unplanned discontinuation. Video monitoring was feasible and associated with lower supervision costs than one-to-one NA supervision. Larger samples in multiple centers are needed to confirm the safety, acceptability, and efficacy of CVM.

Background: The feasibility of telemedicine in diagnosing and treating nonacute headaches, such as primary headaches (migraine and tension-type) and medication-overuse headaches has not been previously investigated. By eliminating the need of travel to specialists, telemedicine may offer significant time and money savings., Objectives: Our objective was to estimate the acceptance of telemedicine and investigate the feasibility and cost savings of telemedicine consultations in diagnosing and treating nonacute headaches., Methods: From September 2012 to March 2015, nonacute headache patients from Northern Norway who were referred to neurologists through an electronic application system were consecutively screened and randomized to participate in either telemedicine or traditional specialist visits. All patients were consulted by two neurologists at the neurological department in Tromsø University Hospital. Feasibility outcomes were compared between telemedicine and traditional groups. Baseline characteristics and costs were then compared between rural and urban patients. Travel costs were calculated by using the probabilistic method of the Norwegian traveling agency: the cheapest means of public transport for each study participant. Loss of pay was calculated based on the Norwegian full-time employee's average salary: < 3.5 hours=a half day's salary, > 3.5 hours spent on travel and consultation=one day's salary. Distance and time spent on travel were estimated by using Google Maps., Results: Of 557 headache patients screened, 479 were found eligible and 402 accepted telemedicine participation (83.9%, 402/479) and were included in the final analyses. Of these, 202 received traditional specialist consultations and 200 received telemedicine. All patients in the telemedicine group were satisfied with the video quality, and 198 (99%, 198/200) were satisfied with the sound quality. The baseline characteristics as well as headache diagnostics and follow-up appointments, and the investigation, advice, and prescription practices were not statistically different between the two randomized groups. In addition, telemedicine consultations were shorter than traditional visits (38.8 vs 43.7 min, P<.001). The travel cost per rural individual (292/402, 73%) was €249, and estimated lost income was €234 per visit. The travel cost in the urban area (110/402, 27%) was €6, and estimated lost income was €117 per visit. The median traveling distance for rural patients was 526 km (range 1892 km), and the median traveling time was 7.8 hours (range 27.3 hours). Rural patients had a longer waiting time than urban patients (64 vs 47 days, P=.001), and fewer women were referred from rural areas (P=.04). Rural women reported higher pain scores than urban women (P=.005)., Conclusion: Our study shows that telemedicine is an accepted, feasible, time-saving, and cost-saving alternative to traditional specialist consultations for nonacute headaches., Trial Registration: Clinicaltrials.gov NCT02270177; http://clinicaltrials.gov/ct2/show/NCT02270177 (Archived by WebCite at http://www.webcitation.org/6hmoHGo9Q).

Many video-based techniques for assessing postures at work have been developed. Choosing the most appropriate technique should be based on an evaluation of different alternatives in terms of their ability to produce posture information at low input costs, i.e. their cost efficiency. This study compared four video-based techniques for assessing upper arm postures, using cost and error data from an investigation on hairdressers. Labour costs associated with the posture assessments from the video recordings were the dominant factor in the cost efficiency comparison. Thus, a work sampling technique associated with relatively large errors appeared, in general, to be the most cost-efficient because it was labour-saving. Measurement bias and other costs than labour cost for posture assessment influenced the ranking and economic evaluation of techniques, as did the applied measurement strategy, i.e. the numbers of video recordings and repeated assessments of them., Practitioner Summary: The cost efficiency of four video-based techniques for assessing upper arm postures was compared. Work sampling techniques were in general more cost efficient than continuous observations since they were labour-saving. Whilst a labour cost dominated the comparison, 'hidden costs', bias and measurement strategy also influenced this dominance.

Purpose: The aim of this study was to establish a method to observe vocal fold vibration using a low-cost high-speed laryngeal imaging system., Procedures: We assembled a high-speed imaging system with a consumer digital camera and a rigid laryngeal endoscope. The camera can shoot digital images at a rate of 1,200 frames per second and be purchased for about USD 1,000 in Japan., Results: We examined the normal and pathological vocal folds of 215 subjects with our new system and analyzed the vocal fold vibration in these subjects by playback of a video and kymograph images., Conclusions: Our high-speed laryngeal imaging system is highly cost-effective and can be a useful tool for examining the vocal folds of patients with voice disorders., (Copyright © 2012 S.

Background Context: Cognitive behavioral therapy has been used successfully in acute low back pain (LBP) treatment, but the use of a cognitive behavioral videotape as an adjunct to treatment has not been studied., Purpose: To determine outcomes for patients with acute LBP receiving a videotape designed to change beliefs and behaviors compared with a standard instructional videotape., Study Design/setting: Randomized controlled trial; multidisciplinary clinic in an academic setting., Patient Sample: Consecutive subjects with less than 3 months of LBP. Of 224 eligible subjects, 138 participated and completed the initial questionnaires., Outcome Measures: Oswestry Disability Index, Pain and Impairment Relationship Scale, Fear-Avoidance Beliefs Questionnaire; medical costs related to LBP and total medical costs incurred by participants during 1 year of follow-up., Methods: Subjects were randomly assigned to receive a behavioral videotape or a control videotape. Other than the videotape, usual care was provided to each patient., Results: No significant differences in any outcome measures or medical costs between the two groups at 12 months. However, baseline Vermont Disability Prediction Questionnaire was significantly lower in those who completed the entire study compared with those who did not complete the study., Conclusions: Compared with a standard instructional videotape, a behavioral videotape did not change beliefs, outcomes, or costs over 1 year. Cost-effective behavioral interventions with high patient retention rates are needed, especially for those at greatest risk of high utilization of resources.

Purpose: There is little economic research on psychosocial interventions. We aimed to collect data alongside a randomized trial to compare the costs and benefits of three psycho-educational strategies to improve transition to cancer survivorship., Methods: We evaluated the incremental delivery costs per unit increase in energy (using the Medical Outcomes Study vitality scale) or decrease in distress (from the Revised Impact of Events Scale) in the 6 months postintervention. We also evaluated 1-year post-treatment health care costs., Results: The costs of the control, video, and video plus counseling arms were $11.30, $25.85, and $134.47 per person, respectively. The video costs were $2.22 per unit increase in energy compared with control; among women who were the least prepared for transition, the video was more effective, resulting in even lower costs. The video cost $7,275 per unit change in distress versus control, but costs were lower in the subgroup least prepared for transition ($355). The counseling arm was more expensive and less effective than the video for virtually all end points. However, in one group, women more prepared for transition, counseling cost $1,066 per unit decrease in distress compared with the video. Health care costs tended to increase as intervention intensity increased., Conclusion: There are no standards for evaluating cost-effectiveness of trials with psychosocial end points. In this trial, the educational video was the most cost-effective way to improve transition to survivorship. It will be important to confirm whether there is an increased use of services after such interventions and if this represents appropriate use of rehabilitative and supportive care or over-use.

Single-channel video is an established method for assessing the clinical consultation; however, it has limitations. While previous research has concluded that three-channel video recording of clinical consultations offers advantages, using professional equipment made costs prohibitive. In this study we set out to establish whether the benefits of three-channel video could be achieved using low-budget consumer-level equipment. Using a kit assembled for around euro 1000, we produced three-channel video recordings of simulated consultations. We then showed single- and three-channel versions of the videos to a panel of health professionals and recorded their opinions regarding the quality of the material and the level of information presented. We found that our budget three-channel set-up provided the same advantages as professional three-channel video, while the cost and complexity of the process was minimal. It is now affordable as well as feasible to use a budget set-up three-channel video system for training clinicians and assessing the impact of the computer on the consultation.

The use of telepsychiatry technology and services has gained attention among legal and clinical practitioners. In the current article, telepsychiatry is defined, and an innovative model of telepsychiatry care delivery that is in use in a child and adolescent forensic evaluation clinic is examined. Critical factors specific to forensics services are examined, as are those specific to telepsychiatry, including transmission mode, privacy and confidentiality, expense, quality of care, face-to-face versus video transmission, user satisfaction, and liability concerns in the use of telepsychiatry.

Background: Although the videotape method (VTM) is commonly used to record and intrepret ecocardiographic images, many pediatric echocardiographers are considering acquiring to, interpreting from, and storing their images to digital disk using the single-beat digital acquisition method (SBM). The paucity of image redundancy using SBM should translate into improved laboratory efficiency compared with VTM, but hard data are lacking. The purpose of this study was to test the hypothesis that the time to acquire images to videotape using VTM and to disk using SBM would be the same for normal hearts and corresponding congenital heart diseases, but interpretation times would be shorter using SBM., Methods: We measured the times to acquire and interpret 403 echocardiograms using standard VTM from Children's Hospital in Cincinnati, Ohio, and 352 echocardiograms acquired using SBM from Children's Hospital in San Diego, Calif. Diagnostic categories at each site included: (1) normal, (2) simple shunt or isolated valve disease, and (3) multiple-lesion disease., Results: As a group, SBM echocardiograms included more hemodynamic measurements and took more time to acquire (P <.037), but less time to read (P <.001) than corresponding images acquired using VTM. Using SBM, it took more time to acquire normals and isolated valve or shunt lesions, whereas the average time to acquire multiple-lesion disease was the same using both VTM and SBM. With SBM, in contrast, interpretation times were significantly less for all corresponding diagnoses., Conclusion: SBM studies took longer to acquire because more hemodynamic measurements were acquired, but they were read in less time than corresponding VTM studies even though all videotapes were replayed in search fast-forward mode. Pediatric echocardiographers can increase their laboratory efficiency by converting from VTM to SBM.

The cost of recording and archiving digital diagnostic imaging data is presented for a Radiology Department serving a 614 bed University-Hospital with a large outpatient population. Digital diagnostic imaging modalities include computed tomography, nuclear medicine, ultrasound, and digital radiography. The archiving media include multiformat video film recordings, magnetic tapes, and disc storage. The estimated cost per patient for the archiving of digital diagnostic imaging data is presented.

Evaluating conceptual and methodological issues are important considerations when developing a videotape for research intervention. The process of developing a videotape for research involves several critical steps to maintain scientific rigor during the project. Establishing content validity of the videotape script and maintaining scientific integrity while producing the videotape are key components. Issues such as copyright and intellectual property are important considerations. The use of videotape provides a consistent method of providing information to research subjects. Careful attention to the research process during each phase of development of the videotape will enhance the success of the project.

Background: Although digital and videotaped images are known to be comparable for the evaluation of left ventricular function, their relative accuracy for assessment of more complex anatomy is unclear. We sought to compare reading time, storage costs, and concordance of video and digital interpretations across multiple observers and sites., Methods: One hundred one patients with valvular (90 mitral, 48 aortic, 80 tricuspid) disease were selected prospectively, and studies were stored according to video and standardized digital protocols. The same reviewer interpreted video and digital images independently and at different times with the use of a standard report form to evaluate 40 items (e.g., severity of stenosis or regurgitation, leaflet thickening, and calcification) as normal or mildly, moderately, or severely abnormal. Concordance between modalities was expressed at kappa. Major discordance (difference of >1 level of severity) was ascribed to the modality that gave the lesser severity. CD-ROM was used to store digital data (20:1 lossy compression), and super-VHS videotape was used to store video data. The reading time and storage costs for each modality were compared., Results: Measured parameters were highly concordant (ejection fraction was 52% +/- 13% by both). Major discordance was rare, and lesser values were reported with digital rather than video interpretation in the categories of aortic and mitral valve thickening (1% to 2%) and severity of mitral regurgitation (2%). Digital reading time was 6.8 +/- 2.4 minutes, 38% shorter than with video (11.0 +/- 3.0, range 8 to 22 minutes, P <.001). Compressed digital studies had an average size of 60 +/- 14 megabytes (range 26 to 96 megabytes). Storage cost for video was A$0.62 per patient (18 studies per tape, total cost A$11.20), compared with A$0.31 per patient for digital storage (8 studies per CD-ROM, total cost A$2.50)., Conclusion: Digital and video interpretation were highly concordant; in the few cases of major discordance, the digital scores were lower, perhaps reflecting undersampling. Use of additional views and longer clips may be indicated to minimize discordance with video in patients with complex problems. Digital interpretation offers a significant reduction in reading times and the cost of archiving.

Purpose: The goal of this work was to determine a radiologist's ability to detect solitary pulmonary nodules on helical CT using both video (cine) viewing and film-based viewing., Method: Sixty-five chest helical CT studies were reviewed. Six radiologists searched for 40 lung nodules on CT images presented in three formats. Film-based viewing of images at 10 and 5 mm increments was performed with a light box. Video viewing of the same examinations was performed in 5 mm increments at 2 frames/s. The area under the receiver operating characteristic curve (Az) measured the observer's ability to detect nodules., Results: The Az was 0.948 for the video viewing, 0.844 for 5 mm increment film-based viewing, and 0.879 for 10 mm increment film-based viewing. There were no statistically significant differences., Conclusion: Lung nodules can be detected with similar detection rates when viewing conventional film or videotaped helical CT images. Videotaped images incur a lower cost, an important consideration in mass screening for lung cancer.

Deaf sign language transmitted by video requires a temporal resolution of 8 to 10 frames/s for effective communication. Conventional videoconferencing applications, when operated over low bandwidth telephone lines, provide very low temporal resolution of pictures, of the order of less than a frame per second, resulting in jerky movement of objects. This paper presents a practical solution for sign language communication, offering adequate temporal resolution of images using moving binary sketches or cartoons, implemented on standard personal computer hardware with low-cost cameras and communicating over telephone lines. To extract cartoon points an efficient feature extraction algorithm adaptive to the global statistics of the image is proposed. To improve the subjective quality of the binary images, irreversible preprocessing techniques, such as isolated point removal and predictive filtering, are used. A simple, efficient and fast recursive temporal prefiltering scheme, using histograms of successive frames, reduces the additive and multiplicative noise from low-cost cameras. An efficient three-dimensional (3-D) compression scheme codes the binary sketches. Subjective tests performed on the system confirm that it can be used for sign language communication over telephone lines.

Objective: This is an evaluation of a telemedicine system for the rapid interpretation of neonatal echocardiograms from a regional, level III neonatal intensive care unit (NICU). The use of telemedicine to support the cardiology needs of NICUs is increasing. However, there is very little published objective information regarding health outcomes or costs resulting from such telemedicine systems. The primary hypothesis tested was that the utilization of a telemedicine system for the interpretation of neonatal echocardiograms reduces the intensive care length of stay of low birthweight (LBW) infants., Study Design: All infants who were admitted to neonatal intensive care at New Hanover Regional Medical Center during the first six months of the system were studied by the use of echocardiograms. They were compared with infants who were born in the same period of the previous year. The outcome measures were the intensive care length of stay, rate of transfer to academic medical centers, and mortality rate., Results: A statistically non-significant reduction of 5.4 days in the intensive care length of stay (LOS) of low birthweight infants was observed (p = 0.37). The cost per echocardiogram transmitted was calculated at $33 compared to previous method of sending videotapes via overnight courier., Conclusions: While the sample size was inadequate to demonstrate improvements in health outcomes, the magnitude of the change and the low costs of the system suggest that this intervention is practical for obtaining rapid diagnostic and treatment support. Larger studies are warranted to confirm these findings and determine whether faster diagnosis and earlier initiation of treatment improve health outcomes of newborn infants.

Objective: To evaluate the effectiveness of an educational visit to help obstetricians and midwives select and use evidence from a Cochrane database containing 600 systematic reviews., Design: Randomised single blind controlled trial with obstetric units allocated to an educational visit or control group., Setting: 25 of the 26 district general obstetric units in two former NHS regions., Subjects: The senior obstetrician and midwife from each intervention unit participated in educational visits. Clinical practices of all staff were assessed in 4508 pregnancies., Intervention: Single informal educational visit by a respected obstetrician including discussion of evidence based obstetrics, guidance on implementation, and donation of Cochrane database and other materials., Main Outcome Measures: Rates of perineal suturing with polyglycolic acid, ventouse delivery, prophylactic antibiotics in caesarean section, and steroids in preterm delivery, before and 9 months after visits, and concordance of guidelines with review evidence for same marker practices before and after visits., Results: Rates varied greatly, but the overall baseline mean of 43% (986/2312) increased to 54% (1189/2196) 9 months later. Rates of ventouse delivery increased significantly in intervention units but not in control units; there was no difference between the two types of units in uptake of other practices. Pooling rates from all 25 units, use of antibiotics in caesarean section and use of polyglycolic acid sutures increased significantly over the period, but use of steroids in preterm delivery was unchanged. Labour ward guidelines seldom agreed with evidence at baseline; this hardly improved after visits. Educational visits cost pound860 each (at 1995 prices)., Conclusions: There was considerable uptake of evidence into practice in both control and intervention units between 1994 and 1995. Our educational visits added little to this, despite the informal setting, targeting of senior staff from two disciplines, and donation of educational materials. Further work is needed to define cost effective methods to enhance the uptake of evidence from systematic reviews and to clarify leadership and roles of senior obstetric staff in implementing the evidence.

Objective: The purpose of this study was to describe the cost implications of converting an established videotape review network for obstetric ultrasonography to one based on telemedicine technology., Design: Retrospective review of fixed and non-fixed costs associated with interpreting obstetric ultrasound examinations using both videotape and telemedicine transmission., Subjects: A network of three community offices transmitting 600 obstetric ultrasound examinations per month to a central tertiary level facility., Methods: Sonographers at the community offices record ultrasound examinations onto videotape, which are then sent by courier to a central facility for interpretation. At the completion of this videotaped examination, sonographers repeat the ultrasound scan while transmitting real-time images over a telemedicine link to the central facility. Costs associated with the videotape review technique that can be avoided by converting to telemedicine interpretation were derived and compared with the fixed and non-fixed costs associated with establishing the telemedicine network., Results: For this network, the fixed costs for establishing telemedicine are $101,750. Monthly non-fixed cost savings by eliminating videotape review include $1620 to $2700 for printing still images, $1200 for courier charges and $7000 for fewer repeat ultrasound examinations. Monthly non-fixed costs for the telemedicine network are $2415. Net monthly savings in non-fixed costs for a telemedicine network are therefore $7405 to $8585, which may pay for the initial fixed costs in 12 to 14 months., Conclusions: The high cost of a telemedicine network may be offset by possible savings in non-fixed costs compared with alternative systems for interpreting obstetric ultrasonography.

Electronic archiving of radiology images over many years will require many terabytes of storage with a need for rapid retrieval of these images. As more large PACS installations are installed and implemented, a data crisis occurs. The ability to store this large amount of data using the traditional method of optical jukeboxes or online disk alone becomes an unworkable solution. The amount of floor space number of optical jukeboxes, and off-line shelf storage required to store the images becomes unmanageable. With the recent advances in tape and tape drives, the use of tape for long term storage of PACS data has become the preferred alternative. A PACS system consisting of a centrally managed system of RAID disk, software and at the heart of the system, tape, presents a solution that for the first time solves the problems of multi-modality high end PACS, non-DICOM image, electronic medical record and ADT data storage. This paper will examine the installation of the University of Utah, Department of Radiology PACS system and the integration of automated tape archive. The tape archive is also capable of storing data other than traditional PACS data. The implementation of an automated data archive to serve the many other needs of a large hospital will also be discussed. This will include the integration of a filmless cardiology department and the backup/archival needs of a traditional MIS department. The need for high bandwidth to tape with a large RAID cache will be examined and how with an interface to a RIS pre-fetch engine, tape can be a superior solution to optical platters or other archival solutions. The data management software will be discussed in detail. The performance and cost of RAID disk cache and automated tape compared to a solution that includes optical will be examined.

A simple and low-cost eye monitoring system with infrared illumination was developed. This system consists of a small board mounted with an infrared sensitive CCD camera and its control unit and a swimming goggle; it is light-weight and visualizes eye movements by connecting the output lines of the board to the video input on a monitor. We have found the present system useful in the routine vestibular clinic practice.

The large number of Southeast Asian, Hispanic, and Portuguese immigrants in Rhode Island face formidable language and cultural barriers in gaining access to the health care that they need. As the funding for refugee-specific programs diminishes, the focus is on programs that encourage self-sufficiency, assist in gaining access to mainstream health care, and involve a collaboration among service agencies and the communities they serve. On behalf of a coalition of health care and community agencies, Women and Infants Hospital of Rhode Island received a private foundation grant to produce nine multilingual videotapes that would educate immigrants and refugees about health issues specific to them and help them access the health care system. The project was structured to maximize the involvement of the various communities and to "empower" community members in working with mainstream service agencies. Coalition and other community members provided input into topic selection, script content, and presentation methods for the videotapes that would be culturally appropriate. During the 2-year project, nine videotapes were produced with narration in seven languages. Copies of the videotapes were distributed free of charge to coalition members.

During the past few years, endoscopic technology has moved increasingly toward the use of video equipment. As a GI laboratory manager, one is confronted with many tasks in converting the unit practice from fiberoptic equipment to video equipment. This article will examine the steps in that process.

This paper describes a video-based information system (VISP) for general practice waiting areas, and considers its potential for broadening the range of information which might be made available to patients.

The assessment of videotaped genuine consultations in order to provide feedback to the learner is now a well accepted part of postgraduate training for general practice. This article reports on a pilot study which investigates the adaptation of videotape assessment of genuine patient consultations as an alternative to the present simulated patient interview segments of the examination for Fellowship of the Royal Australian College of General Practitioners. In particular, the study addresses: the feasibility and cost of collecting and assessing a suitable range of videotaped consultations using portable videocamera equipment and remote examiners; the interobserver reliability of four independent examiners; and the correlation between scores on two different rating scales. The results demonstrate that the assessment of videotaped genuine consultations has the potential to become a means of end-point assessment of clinical competence. The problem of how to collect videotapes of a suitable range and number of consultations to permit a candidate to demonstrate proficiency needs to be addressed and will be followed up in a trial of the method during 1990.

A study of the cost of recording and archiving digitally formatted diagnostic images is presented for an academic radiology department serving a 614-bed university hospital and a large outpatient population. The radiological examinations include computed tomography, nuclear medicine, ultrasound, and digital radiography. The archiving management strategies studied include the combined use of computer magnetic tapes, computer disc storage, and multiformat video film recordings. The estimated cost per patient for the archiving of digital diagnostic images is presented.

We evaluated the long-term effectiveness of three cost-effective parent training programs for conduct-problem children. One year posttreatment, 93.1% of families (94 mothers and 60 fathers) were assessed on the basis of teacher and parent reports and home observations. Results indicated that all the significant improvement reported immediately posttreatment were maintained one year later. Moreover, approximately two thirds of the entire sample showed "clinically significant" improvements. There were very few differences between the three treatment conditions except for the "consumer satisfaction" measure indicating that the treatment combining group discussion and video-tape modeling was superior to treatments without both components.

Programs in emergency medicine for medical students are expected to become increasingly organized over the next several years with the development of emergency medicine teaching faculties by medical schools. In this article, the authors describe a clerkship design with three fundamental elements--clinical instruction, classroom instruction, and evaluation--that should be included in an emergency medicine clerkship. Through the use of optimal student scheduling and new information technologies, the yearly cost per student for the classroom teaching and student evaluation sections of the clerkship is $86.65.
