Comparison of MPEG-1 digital videotape with digitized sVHS videotape for quantitative echocardiographic measurements.

Digital format is rapidly emerging as a preferred method for displaying and retrieving echocardiographic studies. The qualitative diagnostic accuracy of Moving Pictures Experts Group (MPEG-1) compressed digital echocardiographic studies has been previously reported. The goals of the present study were to compare quantitative measurements derived from MPEG-1 recordings with the super-VHS (sVHS) videotape clinical standard. Six reviewers performed blinded measurements from still-frame images selected from 20 echocardiographic studies that were simultaneously acquired in sVHS and MPEG-1 formats. Measurements were obtainable in 1401 (95%) of 1486 MPEG-1 variables compared with 1356 (91%) of 1486 sVHS variables (P <.001). Excellent agreement existed between MPEG-1 and sVHS 2-dimensional linear measurements (r = 0.97; MPEG-1 = 0.95[sVHS] + 1.1 mm; P <.001; Delta = 9% +/- 10%), 2-dimensional area measurements (r = 0.89), color jet areas (r = 0.87, p <.001), and Doppler velocities (r = 0.92, p <.001). Interobserver variability was similar for both sVHS and MPEG-1 readings. Our results indicate that quantitative off-line measurements from MPEG-1 digitized echocardiographic studies are feasible and comparable to those obtained from sVHS.

Videotape intervention: producing videotapes for use in nursing practice and education.

The purpose of this article is to describe the process utilized to produce nursing-specific videotapes for application in clinical or educational settings. The three phases, pre-production, production and post-production, are exemplified with the description of the process used by the authors as they developed the Nurseline Video-Assisted Modeling Program (NuVAMP), a video intervention for caregivers of people with dementia that helps them to shape family members' behaviors in activities of daily living. The practical aspects of video production are emphasized, including script writing, budget development, and the video editing process.

Do not roll the videotape: effects of the health insurance portability and accountability act and the law on trauma videotaping practices.

BACKGROUND: We hypothesized that trauma video practices would be affected as a result of Health Insurance Portability and Accountabilty Act (HIPAA) enactment. METHODS: A survey was distributed electronically to coordinators and/or directors of level 1 trauma centers. Centers were queried on demographics, trauma video use, and reasons for changes, if any, in their video practice patterns. Descriptive statistics and chi-square analysis were employed. RESULTS: Survey response rate was 75%. Prior to HIPAA, 58% of responding trauma centers used video compared to 18% now. On a Likert scale of 1-5, video analysis rated 3.80. For those using video currently, the most common purposes are education (91%) and quality assurance (83%). HIPAA has affected the way video is used at one third of these centers. Ten percent receive institutional review board approval for videotaping, 35% get patient consent, and more than half report capturing a poor patient outcome on tape. The most commonly cited reasons for stopping video use were HIPAA and legal concerns about patient privacy, consent, and discoverability (79%). Scarce resources were, in part, to blame at 70% of centers, while video technology was found to be ineffective at only 32%. CONCLUSIONS: A minority of level I trauma centers currently use video, although it is effective according to users. HIPAA and medicolegal concerns have affected its use at some centers and contributed to its abandonment at others.

[The scientific videotape with digital processing in surgery. The new opportunities offered surgery for videotape recording and postprocessing with the use of information and digital technologies].

The facility of the tape recording of a surgical operation, by means of simple manageable apparatuses and at low costs, especially in comparison with the former cinematography, makes it possible for all surgeons to record their own operative activity. Therefore at present the demonstration in video of surgical interventions is very common, but very often the video-tapes show surgical events only in straight chronological succession, as for facts of chronicle news. The simplification of the otherwise sophisticated digital technology of informatics elaboration of images makes more convenient and advisable to assemble the more meaningful sequences for a final product of higher scientific value. The digital technology gives at the best its contribution during the phase of post-production of the video-tape, where the surgeon himself can assemble an end product of more value because aimed to a scientific and rational communication. Thanks to such an elaboration the video-tape can aim not simply to become a good documentary, but also to achieve an educational purpose or becomes a truly scientific film. The initial video will be recorded following a specific project, the script, foreseeing and programming what has to be demonstrated of the surgical operation, establishing therefore in advance the most important steps of the intervention. The sequences recorded will then be assembled not necessarily in a chronological succession but integrating the moving images with static pictures, as drawings, schemes, tables, aside the picture-in picture technique, and besides the vocal descriptive comment. The cinema language has accustomed us to a series of passages among the different sequences as fading, cross-over, "flash-back", aiming to stimulate the psychological associative powers and encourage those critical. The video-tape can be opportunely shortened, paying attention to show only the essential phases of the operation for demonstrate only the core of the problem and utilize at the best the physiological period of active attention of the observer. The informatic digital elaboration has become so easy that the surgeon himself can be able to elaborate personally on his personal computer, with professional and scientific attitude, the sequences of his surgical activity in a product of more general value. His personal engagement also in the phase of post-production gives him the possibility to demonstrate uprightly with images the complex surgical experience of science, skill and ability to communicate, perhaps better than he is able to do with words.

Teaching diagnostic reasoning: using a classroom-as-clinic methodology with videotapes.

OBJECTIVES: The purpose of this study was to examine the effect of a "classroom-as-clinic" format, using videotaped occupational therapy evaluations, on students' diagnostic reasoning skills. In the classroom-as-clinic format, students write a problem list on the basis of preliminary client information before viewing the videotape. METHOD: A post-hoc experimental design was used to compare the accuracy of treatment plan problem lists for two groups of senior occupational therapy students--one group viewed two videotapes of client-therapist interactions without a classroom-as-clinic format (n = 82), and one group viewed the same videotapes within the context of a classroom-as-clinic format (n = 45). Both groups viewed the same two videotapes. Videotape 1 was of a client with a brain stem infarct, and Videotape 2 was of a client with traumatic brain injury. RESULTS: Subjects experiencing a classroom-as-clinic format identified significantly more occupational therapy problems for Videotape 1 than those who did not have preevaluation information. There was no significant difference between the two subject groups in the accuracy of their problem lists for Videotape 2. Only subjects in the non-classroom-as-clinic group showed a significant improvement from Videotape 1 to Videotape 2 in occupational therapy problem identification. CONCLUSION: This study suggests that to be truly effective when used videotapes, the classroom-as-clinic methodology needs to be combined with explicit coaching in problem sensing and problem definition.

CPR instruction by videotape: results of a community project.

STUDY OBJECTIVE: To increase the rate of bystander CPR in a community by use of a free, mailed, 10-minute videotape of CPR instruction. DESIGN: Prospective, randomized intervention trial. One half of the households (8,659) received the free videotape (video-tape group) and were considered the intervention group, and one half (8,659) served as the control (no-videotape group). All households were followed from December 1991 to March 1993 to determine whether a cardiac arrest occurred and who initiated CPR. A telephone interview obtained additional information about circumstances of the arrest and whether members of the household viewed the videotape. SETTING: City of Everett and South Snohomish County, Washington. A commercial mailing list was used to identify 17,318 households with a head of the household who was more than 50 years old. PARTICIPANTS: A case was defined as a cardiac arrest in which CPR was initiated or continued by emergency medical services personnel. Only cardiac arrests due to presumed underlying heart disease were included. Arrests occurring after arrival of emergency medical services personnel were not included. INTERVENTIONS: The intervention was a free 10-minute videotape with CPR instructions mailed to the 8,659 intervention households. Paramedic run reports were reviewed and interviews were conducted with cardiac arrest bystanders to determine who initiated CPR and whether they had received and viewed the videotape. RESULTS: Sixty-five cardiac arrests occurred in the study households: 31 in households that received the videotape and 34 in households that did not review the videotape. The overall rate of bystander CPR was 47% in the videotape group and 53% in the no-videotape group (P = NS). In nine cardiac arrests, an individual was present who had watched the videotape; six of these nine cases (66%) had bystander CPR. CONCLUSION: Mass mailings of CPR instructional videos are likely to be ineffective in increasing the rate of bystander CPR in a community.

Impact of customized videotape education on quality of life in patients with chronic obstructive pulmonary disease.

PURPOSE: To compare the impact of a library of pulmonary rehabilitation videotapes versus an older videotape and usual care on quality of life and ability to perform activities of daily living in persons with chronic obstructive pulmonary disease. METHODS: Two hundred fourteen patients diagnosed with chronic obstructive pulmonary disease, emphysema, or chronic bronchitis were recruited and randomized to receive customized videotapes, standard videotapes, or usual care. Outcome measures included the Fatigue Impact Scale, Seattle Obstructive Lung Disease Questionnaire, and the SF-36(R) Health Survey. RESULTS: Differences in coping skills and emotional functioning on the Seattle Obstructive Lung Disease Questionnaire were found among the 174 subjects who completed the study. The customized videotape group improved by 8.6 and 4.8 points, respectively, whereas the score of the other groups decreased by less than 1 point for the coping skills, and the scores of the standard video and the control groups decreased by 3.0 and 2.1 points, respectively, for emotional functioning (P < .05, all comparisons). The scores using the Fatigue Impact Scale also improved for the customized videotape group, whereas the scores of the others remained unchanged. Videotape users demonstrated better conversion to and retention of exercise habits, with over 80% of customized videotape subjects who reported exercise habits at baseline continuing the habits as compared with 40% in the usual care group. Sedentary subjects at baseline were more likely to begin and maintain exercise if randomized to videotapes. CONCLUSIONS: These findings demonstrate increased quality of life, lower fatigue, and better compliance with a prescribed exercise regimen among subjects using the customized videotapes. There was a significant improvement in emotional functioning and coping skills among customized videotape subjects.

A multi-state survey of videotaping practices for major trauma resuscitations.

The objective of this study was to determine the prevalence and problems, both perceived and actual, associated with videotaping major trauma resuscitations. A cross-sectional two-part survey of trauma centers was conducted. Part 1 determined demographic information and videotaping status. Part 2 asked trauma centers that were not doing videotaping (NVTCs) about their plans, past experience, and perceived problems. Videotaping trauma centers (VTCs) were asked about mechanics, responsibility, utilization, and problems. A total of 221 centers were surveyed; 20% VTCs, 70% NVTCs, and 10% NVTCs that had videotaped in the past (PVTC). Among VTCs, 53% reported problems with videotaping including lack of personnel (40%) and time (40%) to administer the program. Videotaping, however, was found to be an effective quality improvement tool in 95% of the VTCs. Of the NVTCs, 70% perceived problems with implementing a videotaping program; these included medicolegal (34%) and patient confidentiality (22%) concerns. Of the PVTCs, 90% stated that they had problems with videotaping including lack of staff support (33%) and lack of personnel to assist with the program (24%). In conclusion, staff participation and adequate personnel outweigh medicolegal concerns as actual videotaping problems. Videotaping is perceived to be an effective performance improvement tool.

Using videotape modeling to prepare children psychologically for surgery: influence of parents and costs versus benefits of providing preparation services.

Sixty pediatric patients having first-time elective surgery participated in this study. Surgery preparation using videotape procedures was employed. The research design included two viewing conditions (with parent present and without parent present) and three treatment procedures (adult-narrated videotape, peer-narrated videotape, and control/no-videotape condition). Results suggested that children who viewed the videotape with their parent present exhibited less preoperative arousal compared to children who did not. The patients undergoing preparation using the videotape model exhibited less arousal, less self-reported anxiety, and less behaviorally rated anxiety when compared to patients who did not view the videotape preparation. There was no difference between the patients who viewed the adult-narrated versus the peer-narrated videotape. In addition, parents who viewed the videotape or whose children viewed the videotape without them exhibited less arousal prior to the operation than parents who did not and whose children did not view the videotape preparation. Finally, a cost-benefit analysis revealed that preparation services could reduce individual and overall medical costs.

Videotaped recording as a method of participant observation in psychiatric nursing research.

This paper describes videotaped recording as a data collection method when conducting participant observation in a psychiatric nursing study. The videotaped episodes were part of the daily life of psychiatric nursing in a hospital environment. The advantages and limitations of using videotaped recording in nursing research will be discussed. This paper is based on two studies. The data consisted of 21 videotaped episodes of nursing report sessions or interdisciplinary team meetings in the psychiatric clinic of a university hospital. The participants consisted of patients, their significant others, nurses, doctors, social workers and physiotherapists. All videotaped material was transcribed verbatim. An essential advantage of videotaping is that most potentially useful interaction and behaviour can be captured. The advantage in terms of the credibility of videotaping was that the investigator was able to review the same videotaped situations again and again. Videotaped material is rich and provides several possibilities for analysing the data. In these studies data and source triangulation enabled the researchers to reduce personal influence on the results. The investigator must also be aware of the limitations concerning this method. The most essential limitations are mechanical problems and the influence of videotaping on behaviour. Careful ethical considerations are important concerning personal privacy, informed consent and respect for the self-determination of psychiatric patients.

Empirical development of brief smoking prevention videotapes which target African-American adolescents.

Two studies are described which provide evaluations for two brief videotapes developed as supplemental materials in the prevention of tobacco use among African-American adolescents. One videotape (the "soap opera") provides a more general audience-oriented presentation of prevention material and it was filmed primarily at a shopping mall, whereas the other videotape (the "rap") provides a "hip-hop generation" presentation, and it was filmed primarily at an outdoor hangout. The first study compared the two videotapes against each other. The second study compared the two videotapes combined in the same presentation, controlling for order of presentation, against a discussion group control. The results of the two studies indicated few differences in receptivity to the two videotapes among primarily African-American and Latino young adolescents. The rap videotape was rated as more accurate in its depiction of the African-American lifestyle, although both videotapes were equally liked. When shown together, the videotapes were not found to be superior in decreasing behavioral intention to smoke compared to a discussion group control. No change in trial of smoking was observed within or across conditions measured over a pre-post summer interval. These data suggest that "culturally sensitive" videotapes have no more of a short-term effect on youth than do other types of brief interventions which involve minority implementers.

Videotapes as enrichment for captive chimpanzees (Pan troglodytes).

The effectiveness of showing videotapes to captive chimpanzees as an environmental enrichment was quantitatively tested. The responses of 10 subjects (3 adult males and 7 adult females) to videotapes of chimpanzees engaging in a variety of behaviors, to videotapes of other animals and humans, and to television programs were compared. Data collection consisted of 20-minute, continuous sampling tests while various videotapes were shown. A total of 400 tests were conducted. Multivariate analysis of variance was applied to measure differences in the duration of eight categories of behavior across videotapes of varying content. No general behavioral differences in response to the tapes based on sex or housing were revealed. However, with the behavior of monitor-watching analyzed alone, we found that individually housed subjects watched the videotapes more than socially housed subjects. When viewing time was averaged across all videotapes, the chimpanzees watched the monitor a mean of 38.4% of the time available. The chimpanzees' behavior varied significantly only when they were watching the videotapes of various human and chimpanzee activities and not when watching a blank screen. A Pearson's correlation indicated that subjects habituated to repeated presentations of the videotapes, although the effect was small numerically. Although this type of enrichment did not extensively alter behavior, it did occupy a significant portion of the subjects' activity budget; thus, the amount of time spent watching the video stimuli indicated that videotapes may be a useful enrichment for captive chimpanzees.

Home alone: methods to maximize tic expression for objective videotape assessments in Gilles de la Tourette syndrome.

Our objective was to test whether at-home videotapes yield enhanced information on tics compared to office-based videotapes and a patient questionnaire on the current anatomical distribution of tics. Ten subjects with Gilles de la Tourette syndrome (age range 8-49 years) who were seen for initial evaluation completed a check list of anatomical areas currently affected with tics, and underwent a videotape examination according to the Rush Videotape Protocol. Each patient/family conducted the same protocol at home at the same time of day within 48 hours. We rated two tapes in random order using the modified published scoring method for the Rush Video-based Tic Rating Scale. Two environments were compared, the doctor's office and at home, with videotapes taken in three conditions: patient engaged in relaxed conversation, patient quietly seated with filmer in the room, and patient quietly seated alone in the room. Data were analyzed using a 2-factor repeated-measures analysis of variance (ANOVA), followed by Wilcoxon signed rank tests. All patients provided excellent quality videotapes that could be scored without difficulty. Environment (office vs. home) and Condition (conversation, quiet with observer, quiet and alone) were both highly significant (P < .0001) and did not interact (P = .54). The highest tic scores for total tic impairment occurred at home with the patient alone (mean score 14.5), and the lowest yield occurred in the office with an observer present (mean score 5.4), the setting closest to the clinical neurological examination. The Home/Alone video segments revealed tics not otherwise seen. Patient questionnaires on body regions recorded more areas than observed in the office videotape, but patients were unaware of several tics captured on the Home/Alone segment. Patients can produce videotapes for objective tic assessments. Because at-home videotapes consistently yield higher tic expressions than in-office films and capture tics that are not appreciated by patients, this methodology is well-suited for enhanced retrieval of objective data on tic expression.

The figure rating scale as an index of weight status of women on videotape.

OBJECTIVE: To determine whether Stunkard's Figure Rating Scale (FRS) is a valid and reliable index of weight status when an unbiased observer assigns the figure ratings of adult women viewed on videotape. RESEARCH METHODS AND PROCEDURES: Seventy-two women drawn from a community sample participated in a videotaped study in which height and weight were measured. The FRS is a rating scale displaying 9 silhouettes ranging from very thin to very obese. Women were assigned a figure rating "in-person" by a research assistant (FRS used as a 17-point scale) and by additional research assistants viewing women only on videotape (FRS used as both a 17- and 9-point scale). Pearson's correlation coefficients were calculated for in-person figure ratings, mean videotape figure ratings, and BMI. RESULTS: BMI and in-person figure ratings were highly correlated (r = 0.91), as were BMI and both mean 17-point videotape figure ratings and mean 9-point videotape figure ratings (r = 0.89 and 0.87, respectively). Inter-rater agreement for in-person figure ratings and mean 17-point videotape figure ratings was 0.86, and agreement between in-person figure ratings and mean 9-point videotape figure ratings was 0.82. DISCUSSION: The FRS can be used as an index of women's weight status by an unbiased observer, with subjects viewed in-person or on videotape.

A videotape intervention for sexual counseling after myocardial infarction.

OBJECTIVE: The purpose of this study was to describe the development and testing of a videotape intervention for sexual counseling after myocardial infarction (MI). INTERVENTION: A videotape was developed as a research intervention for sexual counseling after MI. The concepts of sexual integrity, quality of life, and stress and coping were key concepts underpinning the intervention. This article describes the development of the videotape and its content, including considerations for planning, testing, and producing a videotape for research. The videotape intervention is currently being used in a study of patients with MI who are pretested while hospitalized and posttested at 1, 3, and 5 months after MI. Subjects in the treatment group receive the videotape to view in the privacy of their home. Control subjects receive the videotape after the 5-month follow-up period. All subjects receive the usual written and verbal instructions while hospitalized. OUTCOME MEASURES: The 5 outcome variables tested in the study with the videotape are quality of life, knowledge, anxiety, sexual satisfaction, and return to sexual activity. CONCLUSION: The use of a videotape intervention in the home setting provides an additional method of patient education. This approach appears ideal for this sensitive topic.

Videotape increases parental knowledge about pediatric pain management.

UNLABELLED: Pediatric pain management often depends on parents recognition and assessment of their child's pain and their beliefs as to whether the pain should be treated. Parental misconceptions concerning pain assessment and pain management may therefore result in inadequate pain treatment, particularly in patients who are too young or too developmentally handicapped to self-report their pain. We hypothesized that viewing a concise, educational videotape would provide parents with instructive information that could correct misconceptions concerning pain and pain management in children. To do this, we evaluated the impact of an educational videotape on parental responses to a questionnaire about pediatric pain management. Parents of children scheduled for inpatient, postoperative hospital care were studied. After answering 30 questions, parents were randomly assigned to either view (Group 1) or not view (Group 2) a 19-min educational videotape. Immediately after viewing the videotape (Group 1), or 30 min after taking the first test (Group 2), parents were asked to answer the same questionnaire a second time. The effect of seeing the videotape was assessed by comparing post-pre test score differences using paired t-test. One-hundred parents were studied. Randomization was effective in assigning equitable groups. Initial scores of percent answers correct in each group were not different ([mean +/- SD] Group 1 [n = 50]: 68.7% +/- 18.8% vs Group 2 [n = 50]: 61.5% +/- 22.7%; P = 0.09). Viewing the videotape effectively increased test scores: paired t-test within groups demonstrated a significant difference in Group 1 (22.4% +/- 16.5%, P < 0.0001), whereas Group 2 scores changed to a much lesser degree (2.7% +/- 8.3%, P = 0.0271). All parents who viewed the videotape stated that it was informative regarding their understanding of their child's pain management. This study demonstrates the effectiveness of an educational videotape in changing parental knowledge concerning postoperative pediatric pain. This effective and efficient teaching medium may be useful in improving pain management in postoperative pediatric surgical patients. IMPLICATIONS: Pediatric pain management often depends on parents recognition and assessment of their child's pain and their beliefs as to whether the pain should be treated. This prospective, randomized, controlled study demonstrated the effectiveness of an educational videotape in changing parental knowledge concerning postoperative pediatric pain. This effective and efficient teaching medium may be useful in preventing inadequate pain management in postoperative pediatric surgical patients.

Videotape feedback in teaching laryngoscopy.

PURPOSE: To evaluate if videotape feedback provides educational insights for students learning laryngoscopy that they would not otherwise perceive. METHODS: Twenty-six medical students were videotaped while performing laryngoscopy for oral intubation. Before and after reviewing their performance on the videotape, they answered a standardized questionnaire assessing the adequacy of positioning, head movement during laryngoscopy, degrees of neck flexion and head extension, time elapsed, and whether the laryngoscope contacted the upper lip or teeth. After the review, they were asked if being videotaped was distracting, whether it provided new instructional insights and, if so, which was most important. RESULTS: Only 4% of students felt that initial head and neck positioning was suboptimal and this increased to 38% after videotape review (P = 0.029). The perceived inadequacy of positioning seemed related to initial overestimation of head extension (34.0 +/- 15 degrees) compared with that seen on videotape (21.5 +/- 13.5 degrees, P = 0.003). The estimated duration of laryngoscopy was underestimated (55 +/- 32 sec vs. 75 +/- 29 sec, P = .024) before videotape review. Although 26.9% (7/26) of students admitted feeling distracted by the video camera, all felt the experience had educational value. CONCLUSION: Videotape feedback changed students' perception of how they performed laryngoscopy. In particular, head extension was overestimated and duration of laryngoscopy underestimated.

In-vehicle videotaping of drinking driver traffic stops in Oregon.

The purpose of this evaluation is to examine effectiveness of the use of video cassette recorders during traffic stops for drunk driving. This is accomplished by comparing traffic stops that employed video cassette recorders with traffic stops that did not, based on 1341 arrests taken from logs kept by state, city and county enforcement agencies from January 1994 through October 1995. Of the 1341 arrests, 330 used videotaping. Three measures were examined, successful prosecution rate, time until disposition and implied consent hearing requests. If the arrest is videotaped a higher proportion resulted in diversion and about the same proportion resulted in convictions. Fewer were still pending or resolved in the defendant's favor. Also, videotaping appears to shorten the time until case disposition. Finally, the probability that an implied consent hearing will be requested and/or held is clearly higher if the arrest is videotaped. Based on these findings, it was concluded that in-vehicle videotaping of drunk driving arrests is effective to the extent that it leads to more arrests being resolved in the state's favor. However, the evidence that in-vehicle videotaping expedites the case disposition process is somewhat equivocal. Arrests that are videotaped lead to somewhat more speedy case resolutions overall, but also to higher implied consent hearing request rates and presumably more officer time invested in implied consent hearings. In other words, results suggest that videotapes may delay or complicate the process in some instances, but they more often lead to earlier case resolution.
