Analysis of injuries during the 2019 Rink Hockey World Championship.

OBJECTIVES: The purpose of this study is to describe the incidence and characteristics of injuries at the 2019 Rink Hockey World Championship. METHODS: A cross-sectional study was performed among rink hockey athletes from three National Teams (Argentina, Portugal, and Spain). All injuries were reported by the medical staff of each National Team during the preparation period and the competition in the 2019 World Championship (Barcelona, Spain). Injury rate was calculated as the number of injuries per 1000 hours of player-hours of exposure. RESULTS: A total of 91 players (n = 61, 67% male; and n = 30, 33% female) participated in the study: 31 Senior Male (34%), 30 Senior Female (33%), and 30 Under-19 Male (33%). A total of 54 games were played by 9 teams from 3 countries, comprising of 4562 and 4380 hours of total athletic game and training exposure recorded, respectively. Fifty-one injuries (20 injuries with time-loss and 31 medical attention -injuries with no time-loss) were reported. The overall injury incidence rate was 11.2/1000 hours (95% CI, 8.5-14.7). The injury incidence during games (27.5; 95% CI, 11.6-65.2) was higher than the injury incidence during training sessions (3.4; 95% CI, 2-5.7). The incidence rate for game for the entire study period was 8.19 times higher (95% CI, 2.61-21.36) than that for training. The global injury burden was 45.4 days/1000 hours for a total exposure time. Acute was the most frequently documented onset and the non-contact was the most common mechanism. The most frequently reported injuries were head contusion (n = 5, 25%), followed by thigh injuries (n = 3, 15%). CONCLUSIONS: The injury incidence reported in a Rink Hockey international competition was 11.2/1000 hours. The risk of injury was higher during games than during training. Prevention strategies for injuries in these kinds of championships may be worth discussing. The craniofacial injuries were the most frequently reported.

Cardiopulmonary resuscitation skill maintenance for primary care staff: brief training sessions with feedback. / Sesiones breves con retroalimentación: una oportunidad para mantener las habilidades en reanimación cardiopulmonar en profesionales de atención primaria

OBJECTIVES: Cardiopulmonary resuscitation (CPR) feedback applications can facilitate learning in brief training sessions, but they have never been tested in primary care settings. We aimed to see if brief CPR training sessions that include feedback improve the skills of primary care staff. MATERIAL AND METHODS: Randomized trial with a control group and 2 intervention groups (G) using the feedback app and a control group: in G1, the instructor gave spoken feedback to the trainee and both could see the app; in G2, only the instructor giving feedback could see the app; and in G3, the control group, neither the instructor nor the trainee could see the app. All trainees received 10 minutes of instruction on theory followed by 6 minutes of practical instruction according to group assignment. The trainees used a high-quality CPR manikin connected to the Skillreporter feedback app (Laerdal Medical). CPR results were measured immediately before and after training and 6 months later. The main outcome measure was the overall CPR quality score. Secondary outcomes were 6 measures related to compressions and 5 related to ventilation. RESULTS: The main outcome improved with statistical significance in the two intervention groups (G1 and G2) respect to controls (G3). Most secondary outcome measures also improved after training. Trainees in the intervention groups scored better than trainees in G3 on the compression score (G1, P = .012), mean compression depth (G1, P = .001; G2, P = .022), number of compressions with adequate depth (G1, P = .026; G2, P = .019), and number of ventilations at adequate volume (G1, P = .033). The 2 intervention groups achieved statistically similar results. At 6 months, all outcome measures remained slightly improved over baseline levels, there were no between-group differences. CONCLUSION: Brief retraining sessions with feedback are useful for maintaining CPR skills in primary care, but skill improvement is not long lasting.

OBJETIVO: Los dispositivos de retroalimentación en sesiones breves facilitan el aprendizaje en reanimación cardiopulmonar (RCP), pero nunca se han probado para formación en atención primaria (AP). El objetivo fue determinar si estas sesiones mejoran las habilidades de RCP en formación continuada en profesionales de AP. METODO: Estudio prospectivo aleatorizado con 2 grupos de intervención (G1 y G2) y 1 grupo control (G3) en función de las personas que recibían la retroalimentación: G1: instructor y alumno, G2: solamente instructor, G3: ni instructor ni alumno. Todos recibieron 10 minutos de formación teórica común y 6 minutos de formación práctica según grupo, utilizando maniquí Annie QCPR® (Laerdal) conectado al programa de retroalimentación Skillreporter® (Laerdal). Se midieron los resultados, antes y después de la instrucción y a los 6 meses. La variable de resultado principal fue la puntuación total RCP y las variables secundarias fueron 6 relacionadas con compresión y 5 con ventilación. RESULTADOS: La variable de resultado principal mejoró en ambos grupos (G1 y G2) respecto al control (G3). La mayoría de las variables secundarias mejoraron después de la formación. Los grupos de intervención fueron superiores al de control en la puntuación en compresión (G1: p = 0,012), la profundidad media compresiones (G1: p = 0,001, y G2: p = 0,022), el número compresiones con profundidad adecuada (G1: p = 0,026 y G2: p = 0,019) y el número ventilaciones con volumen adecuado (G1: p = 0,033). No hubo diferencias entre grupos intervención en ninguna variable. A los 6 meses, los valores de todas las variables fueron ligeramente superiores a los basales, sin diferencias entre grupos. CONCLUSIONES: Las sesiones breves con retroalimentación son útiles para formación en RCP en AP, pero su validez no es duradera.
