Influence of knowledge, training and experience of observers on the reliability of anthropometric measurements in children.

OBJECTIVE: To elucidate the impact of the observer's level of technical knowledge, training and experience with measuring height and triceps skinfold thickness on the reliability of these measurements in children. Despite of instructions and encouraging careful measurements, these factors may significantly affect measurements and lead to interpretation difficulties, especially of short term growth data. SUBJECTS AND METHODS: A cross-sectional study was designed in which 18 children, aged 2-7 years, were measured in duplo by 12 observers with different backgrounds and levels of experience, protocol knowledge and protocol training. The main outcome measures, precision and accuracy, were expressed as technical error of measurement (TEM) and average bias (AB) in comparison with an expert anthropometrist. RESULTS: As expected, the best educated and most experienced observers scored the best precision and accuracy. By ranking analysis and multiple regressions we learned that precision and accuracy in measuring height and triceps skinfold thickness are mainly predicted by allround knowledge of the measurement protocol (p< 0.05) and the years of experience (p< 0.05). A practical training course of only a few hours does not seem to improve reliability significantly. CONCLUSION: To get a more reliable insight in growth of a child it is important to be aware of the influence on measurement outcome values of protocol knowledge and years of experience. Growth studies should use detailed anthropometric standardization protocols and train people to acquire better insight into these protocols.

Immunization coalitions that work: training for public health professionals.

Coalition development is a major strategy to increase immunization rates. However, if local and state coalitions are to succeed, their staffs need training and technical assistance in coalition development, community planning, and program implementation. The National Coalition Training Institute trains key health agency staff in 87 state, territorial, and urban sites to perform needs assessments, use data to guide planning, plan comprehensive strategies, and evaluate their coalitions. The curriculum is based on training needs that are identified by a national survey of immunization coalitions, effective approaches, and participant evaluation. According to evaluations conducted during its first year, the National Coalition Training Institute is meeting the needs of participants.

Human sperm microinjection into hamster oocytes: a new tool for training and evaluation of the technical proficiency of intracytoplasmic sperm injection.

OBJECTIVE: To design a system for teaching intracytoplasmic sperm injection (ICSI) and to provide a standardized method to assess technical competency. SETTING: University andrology laboratory. DESIGN: Prospective study of method for training ICSI and prediction of ICSI outcome. PATIENT(S): Male infertility candidates for ICSI and fertile donors. INTERVENTION(S): Sperm from 14 fertile donors and 21 oligospermic patients were microinjected into hamster ova. Sperm head decondensation rates (SHD) and oocyte damage rates were measured. Hamster ICSI (HICSI) was used to train technicians, to assess competency, for quality control, and to predict ICSI fertilization. Sperm fertilization potential measured by HICSI was compared with the outcome of ICSI. MAIN OUTCOME MEASURE(S): Sperm head decondensation or fertilization. RESULT(S): Sperm head decondensation was observed in 425 of 773 hamster oocytes with a mean (+/- SD) rate of 60.9 +/- 15.5. Consistency was shown by repetitive testing of the same donor, comparing fresh and frozen semen, and testing of the multiple frozen aliquots of the same ejaculate. Technicians have been trained with this protocol. Excellent initial ICSI success rates for new technicians were demonstrated. Oligospermic semen samples (21 men, 251 hamster ova) tested in the HICSI test exhibited SHD rates from 12% to 100%. The poor outcome of ICSI in clinical cases was predicted by HICSI. CONCLUSION(S): The HICSI provides a method for determining the competency for the ICSI technician and interlaboratory comparison, for the prediction of success of sperm for ICSI.

Public health training on the prevention of youth violence and suicide: an overview.

Although injury is the leading cause of death for Americans aged 40 and under, curricula in U.S. Schools of Public Health rarely include training on injury prevention or control. Domestically and internationally, when the topic of injury is addressed, the focus is often on unintentional injuries. Yet intentional injuries from violence and self-harm (apart from acts of war and terrorism) and the acute and chronic health problems associated with them take a large and often hidden toll on individuals, families, and communities worldwide. Adequate education on the prevention of violence and suicide by teenagers remains missing from public health and medical training. Public health and medical practitioners are confronted by violence-related injury but are provided little formal education on youth violence or suicide, effective responses, or prevention. Adolescents' involvement in violence remains a serious public health problem. Involvement in aggression and self-harm by adolescents leaves them at immediate risk of injury and often has ongoing and negative effects on future development, involvement in community and family life, and risk of morbidity and mortality for self and others. Public health practitioners are at the nexus of health care and service provision at local, state, federal, and multinational levels, and are well suited to provide training and technical assistance on youth violence prevention across disciplines and settings. In this article, training resources, opportunities, and strategies for prevention of the high prevalence of youth violence and suicide in the U.S. are discussed and recommendations for a new public health training initiative are outlined.

Technical and technological skills assessment in laparoscopic surgery.

OBJECTIVES: Surgical appraisal and revalidation are key components of good surgical practice and training. Assessing technical skills in a structured manner is still not widely used. Laparoscopic surgery also requires the surgeon to be competent in technological aspects of the operation. METHODS: Checklists for generic, specific technical, and technological skills for laparoscopic cholecystectomies were constructed. Two surgeons with >12 years postgraduate surgical experience assessed each operation blindly and independently on DVD. The technological skills were assessed in the operating room. RESULTS: One hundred operations were analyzed. Eight trainees and 10 consultant surgeons were recruited. No adverse events occurred due to technical or technological skills. Mean interrater reliability was kappa=0.88, P=<0.05. Construct validity for both technical and technological skills between trainee and consultant surgeons were significant, Mann-Whitney P=<0.05. CONCLUSIONS: Our study demonstrates that technical and technological skills can be measured to assess performance of laparoscopic surgeons. This technical and technological assessment tool for laparoscopic surgery seems to have face, content, concurrent, and construct validities and could be modified and applied to any laparoscopic operation. The tool has the possibility of being used in surgical training and appraisal. We aim to modify and apply this tool to advanced laparoscopic operations.

A haptic interface for virtual simulation of endoscopic surgery.

Virtual reality can be described as a convincingly realistic and naturally interactive simulation in which the user is given a first person illusion of being immersed within a computer generated environment While virtual reality systems offer great potential to reduce the cost and increase the quality of medical training, many technical challenges must be overcome before such simulation platforms offer effective alternatives to more traditional training means. A primary challenge in developing effective virtual reality systems is designing the human interface hardware which allows rich sensory information to be presented to users in natural ways. When simulating a given manual procedure, task specific human interface requirements dictate task specific human interface hardware. The following paper explores the design of human interface hardware that satisfies the task specific requirements of virtual reality simulation of Endoscopic surgical procedures. Design parameters were derived through direct cadaver studies and interviews with surgeons. Final hardware design is presented.

The Pacific Center for Emergency Health: an anatomy of collaborative development and change--the Palau perspective.

Many Pacific Islands Countries (PICs) by their geographic location, isolation, and lack of resources, are at risk for both environmental and man-made disasters. Disaster management (DM) and mitigation is frustrated by the general underdevelopment of DM planning and lack of adequate emergency medical services (EMS) to deal with daily emergencies let alone large-scale emergencies and disasters. To address this, the U.S. Centers for Disease Control and Prevention (CDC) developed and implemented the Pacific Emergency Health Initiative (PEHI) to review and make recommendations regarding the current level of DM/EMS development of select PICs. As a practical next step, a collaborative demonstration project--the CDC--Palau Community College Center for Emergency Health--was established in the Republic of Palau with the purpose of providing training and technical assistance in DM/EMS development for the region. In September 2001 the Center conducted two simultaneous training programs addressing Public Health Disaster Planning (one-week) and pre-hospital First Responder Care (two-weeks). Sixty participants included public health planners, physicians, and fire and police officials from eleven PIC jurisdictions and representatives from the Secretariat of the Pacific Community, South Pacific Applied Geoscience Commission, and the Fiji School of Medicine. Eleven country and state public health disaster plans were initiated. Through CDC's PEHI additional Center training programs are planned through FY 2003.

Effects of two different short-term training programs on the physical and technical abilities of adolescent basketball players.

This study evaluated and compared the effectiveness of two different off-season, short-term basketball training programs on physical and technical abilities of young basketball players. Twenty-seven adolescent basketball players (14.7+/-0.5 years; Tanner stage: 3.5+/-0.5) were randomly divided into a specialized basketball training group (SP, n=10), a mixed basketball plus conditioning training group (MX, n=10) and a control group (n=7). Training included five sessions per week (100-120 min each) and was performed for 4 weeks. Maximal oxygen uptake was similarly improved after SP (4.9+/-1.8%) and MX (4.9+/-1.4%), but there was no effect on ventilatory threshold. Peak and mean power output measured during the Wingate test were also improved by a similar magnitude after SP (21+/-5%) and MX (15+/-6%). Trunk muscle endurance was equally increased (SP: 23+/-4%, MX: 25+/-5%), but arms endurance was improved significantly more after MX (50+/-11%) compared to SP (11+/-14%, p<0.05). Performance in four basketball technical skills was similarly increased (by 17-27%) in both groups, with a tendency for greater improvement of the SP groups in the technical skills of shooting and passing. These results indicate that a SP basketball training program, performed exclusively on-court was as effective as a MX training program in terms of aerobic and anaerobic fitness improvement. Furthermore, the decrease of the total on-court training time in the MX group resulted in a tendency for a smaller improvement of basketball technical skills. In conclusion, both SP and MX training are equally effective in order to limit and/or reverse the detraining effects that occur during the off-season in basketball.
