Instruction of jump-landing technique using videotape feedback: altering lower extremity motion patterns.

BACKGROUND: Anterior cruciate ligament injury prevention programs have used videotapes of jump-landing technique as a key instructional component to improve landing performance. HYPOTHESIS: All videotape feedback model groups will increase knee flexion angles at initial contact and overall knee flexion motion and decrease peak vertical ground reaction forces and peak proximal anterior tibial shear forces to a greater extent than will a nonfeedback group. The secondary hypothesis is that the videotape feedback using the combination of the expert and self models will create the greatest change in each variable. STUDY DESIGN: Controlled laboratory study. METHODS: Knee kinematics and kinetics of college-aged recreational athletes randomly placed in 3 different videotape feedback model groups (expert only, self only, combination of expert and self) and a nonfeedback group were collected while participants performed a basketball jump-landing task on 3 testing occasions. RESULTS: All feedback groups significantly increased knee angular displacement flexion angles [F(6,70) = 8.03, P = .001] and decreased peak vertical ground reaction forces [F(6,78) = 2.68, P = .021] during performance and retention tests. The self and combination groups significantly increased knee angular displacement flexion angles more than the control group did; the expert model group did not change significantly more than the control group did. All feedback groups and the nonfeedback group significantly reduced peak vertical forces across performance and retention tests. There were no statistically significant changes in knee flexion angle at initial ground contact (P = .111) and peak proximal anterior tibial shear forces (P = .509) for both testing sessions for each group. CONCLUSION: The use of self or combination videotape feedback is most useful for increasing knee angular displacement flexion angles and reducing peak vertical forces during landing. CLINICAL RELEVANCE: The use of self or combination modeling is more effective than is expert-only modeling for the implementation of instructional programs aimed at reducing the risk of jump-landing anterior cruciate ligament injuries.

Informed consent for ankle fracture surgery: patient comprehension of verbal and videotaped information.

BACKGROUND: The purpose of our study was to evaluate the effectiveness of using a videotape to give patients information about the risks, benefits, alternatives, and treatment of a common orthopaedic procedure before they sign consent forms. METHODS: During a 9-month period, 48 patients with isolated closed ankle fractures requiring surgical intervention were randomized into two groups that received either videotaped or conventional verbal information regarding consent for surgery. The study group watched a videotape containing information about the risks, benefits, and treatment alternatives, while the control group obtained this information verbally. To determine comprehension and retention, all patients completed a multiple-choice questionnaire immediately after receiving the information, and 37 patients (77%) were available to complete a questionnaire at an average of 10 weeks later. RESULTS: The videotape group outperformed the verbal consent group by 40.1% on the initial questionnaire (p = .0002) and by 27.2% on the followup questionnaire (p = 0.0139). Patients with educational levels of less than or equal to the 12th grade performed 67.8% better on the initial questionnaire after watching the video than after receiving the information verbally. (p = .0001). CONCLUSION: Patients who received information about their surgery on a videotape before giving their consent demonstrated a significant increase in comprehension compared to patients who received this information verbally. The benefit was even greater for patients with lower education levels.

Modeling smoking cessation: exploring the use of a videotape to help pregnant women quit smoking.

This exploratory study examined the acceptability and efficacy of a videotape modeling smoking cessation as an adjunct to smoking cessation advice delivered during prenatal care. In a randomized controlled trial involving 60 women, we compared the delivery of brief smoking cessation advice and a tipsheet to the same advice and tipsheet plus provision of the videotape. Outcomes included opinions about content and acceptability of the videotape, and smoking behavior change during pregnancy. The most highly endorsed features of the videotape were seeing other women quitting smoking (77%), dealing with stress and bad feelings (69%), talking about what to do with urges to smoke (69%), and discussing ways to get support from families and friends (54%). The reported quit rate in the last month of pregnancy, validated by exhaled carbon monoxide levels, and including women lost to follow-up as smokers, was 19.2% in the intervention group and 0% in the comparison group (p = .02). This study suggests that the use of videotapes modeling smoking behavior change may increase the effectiveness of the assistance in quitting smoking that is generally available in obstetric and family practices or public maternity clinics.

Improving the interviewing and self-assessment skills of medical students: is it time to readopt videotaping as an educational tool?

PURPOSE: To evaluate the effect of a videotaping program on third-year medical students' interviewing and self-assessment skills. METHODS: A self-assessment manual, listing and explaining 21 core elements of the medical interview, was developed. After reading the manual, students videotaped an interview and self-assessed their performances. Each student reviewed the videotape with a faculty member who also rated the performance. This process was repeated 1 week later. Changes in group performance, core element performance, and ability to self-assess after the intervention were evaluated by Cohen d values to measure effect size, McNemar chi-square test for repeated measures, and concordance between faculty and student ratings. RESULTS: Sixty students participated in the videotaping study. Students inaccurately self-assessed on the first video 14% of the time. The 6 poorest-performed core elements were the least accurately self-assessed. Lack of concordance between the global rating given by faculty and student identified all students with inflated self-assessment. One review session had a large effect on overall performance and interpersonal skills and a moderate effect on history-taking skills. A large effect on performance was seen for 3 core elements, a moderate effect for 12 elements, and a small effect for the remaining 6 elements. Performance of the core elements that needed improvement did improve in 74% of the students (P <.001). Students' overall ability to self-assess improved significantly (P <.01). CONCLUSIONS: Our videotaping program improved students' interviewing and self-assessment skills and identified students with inflated views of their abilities. Medical educators should re-evaluate and readopt this excellent teaching and learning tool.

Impact of a waiting room videotape message on parent attitudes toward pediatric antibiotic use.

OBJECTIVE: To reduce the injudicious use of antibiotics, we developed an educational strategy that focused on parents of pediatric patients and their physicians. METHODS: This intervention was conducted in 5 pediatric practices in Arkansas during a 9-month period. Baseline data on parent attitudes about antibiotics and physician practice habits were measured by questionnaire. During the following 36 weeks, an educational videotape about the judicious use of antibiotics was played in waiting rooms. The videotape on antibiotics used a standard script based on the recommendations of the American Academy of Pediatrics. The physicians and staff at each site were actors in the videotape. During week 2 and week 36 of videotape use, parent attitudes were measured again. After the baseline week, the physicians and staff in each site were provided a standard in-service review of the American Academy of Pediatrics recommendations for judicious use of antibiotics. A study nurse recruited patients, administered questionnaires, and reviewed charts on-site. RESULTS: Parents who were exposed to the videotape were significantly less inclined to seek antibiotics for viral infections. Passively provided pamphlets were not read. No significant change in antibiotic prescribing by physicians was seen. CONCLUSION: Parent-focused passive education tools are effective at changing parent attitudes toward the use of antibiotics. Although physicians have blamed parent attitudes and demands for the overuse of antibiotics, changes in parent attitudes in this study were not associated with changes in prescribing rates. Changes in parent attitudes may be necessary but do not seem sufficient for changes in antimicrobial prescribing patterns.

Analysis of videotaped consultations to certify competence.

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.

Introducing a procedure using videotape instruction: the case of the lateral birth position.

BACKGROUND: Videotapes have been variably successful in teaching physical examination skills, interviewing strategies, and clinically relevant didactic material to medical students, residents, and physicians. The literature does not include evaluations of their success in introducing procedural techniques into clinical practice. OBJECTIVES: This study assessed whether the presentation of an instructional videotape influenced the adoption of a specific technique, assisting birth in the lateral position. METHODS: Family practice residents, faculty, and physicians participated in educational presentations that reviewed how to assist childbirth in the lateral position. Three different formats were used for the presentations; an instructional videotape formed the core element of each presentation. Immediately following the presentations, and on one other occasion 4-6 months later, the participating physicians received questionnaires surveying their use of the lateral birth position. RESULTS: Approximately 30% of the respondents who had not previously used the position used the lateral birth technique. Of the remaining respondents who had not used the technique, 64% considered using the technique with their laboring patients. Physicians who viewed the videotape in concert with other educational interventions were more likely to have adopted the new birth technique (P = .03). CONCLUSIONS: An instructional videotape, as part of a structured, interactive presentation, can be used successfully to introduce a procedure into the clinical practices of family physicians.

Use of videotaping to evaluate pediatric resident performance of health supervision examinations of infants.

STUDY OBJECTIVES: To demonstrate reliability of a method for evaluating pediatric resident performance of health supervision examinations of infants using real patients and to evaluate pediatric resident performance of health supervision examinations of infants before and after an educational intervention consisting of a 6-month ambulatory rotation combined with video-assisted review of resident performance of the examination. DESIGN: Longitudinal cohort study in which all second-year residents were enrolled. Residents' preintervention (baseline) videotapes were compared with postintervention videotapes. Each resident served as his or her own control. SETTING: University hospital pediatric resident continuity clinic. SUBJECTS: Sixteen second-year pediatric residents who were participating in a required 6-month ambulatory rotation. METHOD AND MAIN RESULTS: Reliability study: Using a 51-item instrument derived from the American Academy of Pediatrics Guidelines for Health Supervision, trained raters blind to the sequence and dates of the videotaped health supervision examinations independently rated 44 resident encounters (a minimum of two raters per tape) and achieved good interrater reliability (kappa = 0.80). Intervention study: After a 6-month ambulatory rotation which included resident-faculty reviews of preintervention videotapes, residents showed a 14% mean improvement in performance scores for the examination (P < .05). CONCLUSIONS: The results indicate that videotaped health supervision examinations using real patients can be reliably evaluated by observational techniques in a continuity practice. A 6-month ambulatory block rotation coupled with video-assisted interactive review of examinations is associated with measurable improvement in resident performance on the postintervention test.

Producing videotapes for cancer education: methods and examples.

PURPOSE/OBJECTIVES: To describe a systematic process to produce videotapes for cancer education and research. DATA SOURCES: Published research and education articles, patient and health education models, the National Cancer Institute's health communication model, and personal experiences. DATA SYNTHESIS: Videotapes provide a consistent form of teaching, are a familiar medium to most patients, and can communicate concepts in a realistic and visual manner. To enhance the acceptability, relevancy, and understanding of cancer messages, target-audience assessment and learner verification should be given special attention. Practical aspects of preproduction, production, and post-production phases, including budget considerations, script development, talent/narration, and location scouting, are important factors to address in producing videotapes. CONCLUSIONS: Cancer education videotapes can be developed through the use of a systematic process and by addressing practical aspects of video production. Assessment and inclusion of target audience members throughout the development process help to ensure that content meets learners' needs. IMPLICATIONS FOR NURSING PRACTICE: Nurses can produce effective educational videotapes by using a systematic framework to guide their efforts. Attention to practical aspects of production is necessary to create high-quality programs that are effective in terms of time, energy, and money.

Intraobserver and interobserver reliability of videotaped laparoscopy evaluations for endometriosis and adhesions.

OBJECTIVE: To determine the intra- and interobserver reliability of evaluations during videotaped laparoscopy, with real-time laparoscopy as the "gold standard." DESIGN: Prospective evaluation. SETTING: University hospital. PATIENT(S): Women who underwent laparoscopy for chronic pelvic pain, sterilization, or infertility workup. INTERVENTION(S): Real-time laparoscopies were videotaped and scored then later reassessed. MAIN OUTCOME MEASURE(S): Intra- and interobserver levels of agreement between evaluations for endometriosis and adhesions. RESULT(S): With the use of reassessments on 90 (videotaped) laparoscopies, the intra- and interobserver levels of agreement between the scorings for endometriosis were found to be substantial, except for ovarian implantations. A high agreement was found in the staging of endometriotic disease. The intra- and interobserver levels of agreement for scoring adhesions were only fair to moderate, and a substantial number of differences between measurements in adhesion total scores was found. No systematic difference between the number of disagreements was observed in either setting. CONCLUSION(S): Although special attention has to be given to the assessments of ovarian lesions, the evaluations of videotaped laparoscopies for endometriosis were reliable and justified the use of recorded findings. Because evaluations of adhesions during videotaped laparoscopy are not reliable, in some cases a second laparoscopy may need to be performed.

Still photography versus videotaping for documentation of cecal intubation: a prospective study.

BACKGROUND: Documentation of cecal intubation is important for credentialing and continuous quality improvement. However, convincing cecal photographs can be difficult to obtain. The aims of the study were to determine (1) the anatomic variations and photographic factors associated with convincing cecal photographs; (2) whether a prospective attempt to capture specific features resulted in more convincing photographs; and (3) how a prospective attempt at capturing convincing cecal features during still photography compares with videotaping as a method of documenting cecal intubation. METHODS: A single examiner evaluating 165 consecutive patients photographed the entire cecum from just distal to the ileocecal valve, the appendiceal orifice, the ileocecal valve orifice, and in the last 110 consecutive cases, the terminal ileum, if it could be intubated. The photographs were then scored by 8 experts according to how convinced they were that cecal intubation had occurred. Features associated with high and low scores were determined, and 50 additional consecutive patients were photographed with a specific effort to capture these features, along with videotaping of the cecum. These photographs and videotapes were then scored by 7 of the 8 experts on a scale of 1 to 5, with 5 representing "definitely the cecum." RESULTS: There was marked variation in scores of still photographs among reviewers. A combination of photographs produced the highest mean score and the highest percentage of scores that were either "probably" or "definitely" of the cecum. The photograph of the cecum from just distal to the ileocecal valve was most convincing and the terminal ileum photograph was least convincing. In the 50 cases in which an attempt was made to capture specific features, mean scores improved for the overall cecal photograph by 0.10, the appendiceal orifice by 0.23, the ileocecal valve lips by 0.20, and the terminal ileum by 0. 19. The cecum, appendiceal orifice, valve lips, and terminal ileum photographs for the last 50 patients were scored higher than those from the first 165 patients by 4, 4, 4, and 5 reviewers, respectively. Videotapes were consistently convincing (overall mean score 4.78 out of 5) and were scored more convincing than the combination of still photos from the final 50 cases by 6 of 7 reviewers. CONCLUSIONS: Still photography of the cecum can be improved somewhat by attempting to capture specific cecal features. However, because of anatomic variation among normal individuals, still photography remains inconsistently convincing. A combination of photographs is most convincing. Videotaping of the cecum is consistently convincing and would appear to serve effectively as a means of documenting cecal intubation rates for the purposes of continuous quality improvement and credentialing.

Effects of a videotape information intervention at discharge on diet and exercise compliance after coronary bypass surgery.

BACKGROUND: This study evaluated the relative effects on compliance with recommended lifestyle changes of two experimental videotapes that involved different approaches for preparing coronary artery bypass graft (CABG) patients for the posthospital recovery period. The tapes differed in the extent to which they portrayed the recovery period as a steady, forward progression versus a series of "ups and downs." METHODS: Two hundred sixteen male and female CABG patients were assigned randomly either to view one of the two videotapes before discharge from the hospital or to receive only the standard discharge preparation provided by the hospital. All patients completed measures of anxiety and self-efficacy at discharge, 1 month and 3 months after discharge from the hospital. Patients also completed measures of dietary fat consumption and activity level 1 and 3 months after discharge. RESULTS: Relative to controls, patients who viewed either of the videotapes before hospital release reported higher self-efficacy for adhering to the recommended low-fat diet both at discharge and 1 month after surgery. Viewing either of the videotapes also resulted in significantly less dietary fat intake 1 month after hospital release compared with controls. Patients who viewed the tape that portrayed the recovery period as consisting of ups and downs also reported significantly more frequent moderate exercise at 1 month and more frequent strenuous exercise 3 months after discharge. CONCLUSIONS: The experimental videotapes proved to be an effective method for increasing dietary and exercise compliance during the first 3 months after CABG.

[Effectiveness of videotape education for mothers of prematurity].

To investigate the effectiveness of an educational videotape on preterm mothers' knowledge, confidence, perceived stress, and social support, mothers who had given birth prematurely were recruited to participate in this study. Sixty-two mothers were randomly assigned to a control or experimental group. During hospitalization, mothers assigned to the experimental group received additional educational videotape which was designed by researchers for this particular study, regarding the knowledge and skills of caring for premature infants. While mothers in the control group received routine educational care. Both groups of mothers filled out the questionnaire including knowledge of prematurity, maternal confidence, perceived stress and perceived social support at three time periods (before discharge, one week after discharge, and one month after discharge). The findings indicated that mothers who received a videotape education reported having higher knowledge and confidence of caring for their preterm babies than mothers who were in the control group. Moreover, mothers in the experimental group perceived lower stress than the control group mothers when their babies were one month old. The scores of perception of stress, parity, and receiving a videotape education are the best predictors to maternal confidence a week after discharge. Further, the mothers' perception of stress, parity, and the perception of social support can predict and explain 47.1% of the variance of the maternal confidence. These results can apply to clinical practice for nursing mothers who have given preterm births. A convenient videotape education can improve mothers' knowledge and confidence of caring for their premature babies at home.

Impact of advance directive videotape on patient comprehension and treatment preferences.

OBJECTIVE: To examine the effects of an advance directive videotape on patient comprehension of advance directive concepts and preferences for resuscitation. DESIGN: Pilot study, randomized cohort trial. SETTING: Extended Care and Rehabilitation Center, Veterans Affairs Medical Center, Durham, NC. PARTICIPANTS: Thirty-six residents of the center; mean age, 69 years. INTERVENTIONS: Sixteen subjects observed an advance directive videotape, and 20 subjects observed a health-relative videotape. All subjects received written material and counseling on advance directives. MEASUREMENT: Structured interviews were conducted at three time points relative to the educational program (pretest, posttest, delayed posttest), measuring comprehension of two advance directive concepts (living will and cardiopulmonary resuscitation) and resuscitation preferences based on hypothetical clinical vignettes. Mean comprehension and mean resuscitation preference scores were derived for each time point. RESULTS: The mean comprehension score improved an average of 1.6 points for all subjects from pretest to delayed posttest (P < .001); however, score changes were not significantly different between the two video groups (P = .39). Mean resuscitation preference scores were stable over time, and there were no significant score differences between the two video groups. CONCLUSION: The advance directive videotape did not significantly affect resuscitation preferences or comprehension of selected advance directive concepts.

Use of videotape in the preparation of children for cardiac catheterization.

To help children with congenital heart disease, and their parents, cope with the stress of hospitalization for cardiac catheterization, a videotape was developed entitled "Leonard Z. Lion Presents ... Learning About Your Heart Catheterization." Fifty-three patients with congenital heart disease, 3 to 12 years of age, were randomly assigned to experimental (N = 31) or control (N = 22) groups. Each viewed the catheterization videotape or an unrelated control videotape before cardiac catheterization. The child's knowledge, anxiety, and adjustment during and after hospitalization for catheterization were evaluated. The experimental group displayed a significantly greater knowledge of events and sensations experienced during hospitalization than controls (P less than .0001). Children in the experimental group tended to sleep more during the catheterization procedure (P = .05) and when awake to ask more questions (P = .02). After discharge, the experimental group also tended to demonstrate more independent behavior. We conclude that viewing this videotape on heart catheterization helped children with congenital heart disease to cope with the stress of hospitalization for the procedure.

Effects of preparatory videotapes on self-efficacy beliefs and recovery from coronary bypass surgery.

This study evaluated the relative effects of three experimental videotapes that involved different approaches for preparing coronary artery bypass graft (CABG) patients for surgery and the inhospital recovery period. One of the tapes conveyed information via a health care expert only. The other two featured the same health care expert and also included clips of interviews with patient models. These latter two tapes differed in the extent to which they portrayed the recovery period as a steady, forward progression or as consisting of "ups and downs". Two hundred fifty-eight male CABG patients were randomly assigned to view one of the three videotapes on the evening prior to surgery or to a control condition. Overall, patients who viewed any of the videotapes felt significantly better prepared for the recovery period, reported higher self-efficacy for using the incentive spirometer and for speeding their recovery, performed more repetitions with their incentive spirometer each time they used it postoperatively, had shorter intensive care unit stays, and were released from the hospital more quickly than patients in the control condition. There was also evidence that patients' self-efficacy beliefs for speeding recovery directly mediated the effects of the videotapes on length of stay both in the intensive care unit and in the hospital.

The Vancouver sedative recovery scale for children: validation and reliability of scoring based on videotaped instruction.

We originally developed and tested the Vancouver Sedative Recovery Scale (VSRS) to measure recovery from sedation following paediatric open heart surgery and reported excellent clinical inter-observer reliability. We now report a new study using videotape instruction of novice raters and videotaped case examples to determine whether the instruction produces adequate skill with the VSRS. Inter-rater reliability was assessed using videotapes of 16 children across a range of ages (six months to six years), and all levels of sedation (unresponsive to fully awake). Variably randomized subsets of six of the 16 test cases were randomly assigned to be rated by each of 16 video-instructed ICU staff volunteers, according to a balanced incomplete block design, such that every pair of raters assessed two children in common. The validity of the ratings from the video-instructed raters was assessed by comparison with "gold standard" scores from two experts who rated all 16 children clinically as the test cases were videotaped. The experts were in agreement themselves (intraclass correlation of 0.976). The correlation between the novice scores (average of six ratings per video) and the live clinical scores (average of two expert ratings) was 0.977 over the 16 test cases. On average, the mean expert rating was slightly higher, but the difference was negligible. (The differences between the mean ratings of the experts and novices for 13 of the 16 videos are very close to zero, while the other three differences, from technically less good videos, are two standard deviations away from zero). The VSRS, video instruction method and incomplete block design may be of use to other clinicians and investigators.

Fostering juror comfort: effects of an orientation videotape.

The purpose of the present study is to assess the impact of a juror orientation videotape on juror knowledge of the legal system and comfort levels regarding jury service. Juror knowledge and comfort were measured using the Juror Knowledge and Comfort Scale (JKCS). It was hypothesized that jurors exposed to the orientation videotape would be significantly more knowledgeable about the legal system and significantly more comfortable with their role as jurors. It was further hypothesized that there would be a significant correlation between the knowledge scale and comfort scale of the JKCS. Results indicate that jurors exposed to the orientation videotape scored significantly higher on both the knowledge scale and comfort scale than jurors not exposed to the orientation videotape. There is also a significant correlation between the juror knowledge and comfort components of the JKCS. The implications of the findings and directions for future research are discussed.
