Teamwork in the viscous oceanic microscale.

ABSTRACT: Nutrient acquisition is crucial for oceanic microbes, and competitive solutions to solve this challenge have evolved among a range of unicellular protists. However, solitary solutions are not the only approach found in natural populations. A diverse array of oceanic protists form temporary or even long-lasting attachments to other protists and marine aggregates. Do these planktonic consortia provide benefits to their members? Here, we use empirical and modeling approaches to evaluate whether the relationship between a large centric diatom, Coscinodiscus wailesii, and a ciliate epibiont, Pseudovorticella coscinodisci, provides nutrient flux benefits to the host diatom. We find that fluid flows generated by ciliary beating can increase nutrient flux to a diatom cell surface four to 10 times that of a still cell without ciliate epibionts. This cosmopolitan species of diatom does not form consortia in all environments but frequently joins such consortia in nutrient-depleted waters. Our results demonstrate that symbiotic consortia provide a cooperative alternative of comparable or greater magnitude to sinking for enhancement of nutrient acquisition in challenging environments.

Project description:BackgroundIn health care, teamwork skills are critical for patient safety; therefore, great emphasis is placed on training these skills. Given that training is increasingly designed in a blended way, serious games may offer an efficient method of preparing face-to-face simulation training of these procedural skills.ObjectiveThis study aimed to investigate the teamwork principles that were used during gameplay by medical students and teamwork experts. Findings can improve our understanding of the potential of serious games for training these complex skills.MethodsWe investigated a web-based multiplayer game designed for training students' interprofessional teamwork skills. During gameplay, 4 players in different roles (physician, nurse, medical student, and student nurse) had to share information, prioritize tasks, and decide on next steps to take in web-based patient scenarios, using one-to-one and team chats. We performed a qualitative study (content analysis) on these chats with 144 fifth-year medical students and 24 health care teamwork experts (as a benchmark study) playing the game in groups of 4. Game chat data from 2 scenarios were analyzed. For the analysis, a deductive approach was used, starting with a conceptual framework based on Crew Resource Management principles, including shared situational awareness, decision-making, communication, team management, and debriefing.ResultsResults showed that most teamwork principles were used during gameplay: shared situational awareness, decision-making (eg, re-evaluation), communication (eg, closed loop), and team management (eg, distributing the workload). Among students, these principles were often used on a basic level. Among experts, teamwork principles were used with more open forms of speak up and more justification of decisions. Some specific Crew Resource Management principles were less observed among both groups, for example, prevention of fixation errors and use of cognitive aids. Both groups showed relatively superficial debriefing reflections.ConclusionsPlaying a multiplayer game for interprofessional teamwork appears to facilitate the application of teamwork principles by students in all important teamwork domains on a basic level. Expert players applied similar teamwork principles on a moderately high complexity level. Some teamwork principles were less observed among both students and expert groups, probably owing to the artifacts of the game environment (eg, chatting instead of talking). A multiplayer game for teamwork training can elicit the application of important, basic teamwork principles, both among novices and experts, and provides them with a flexible, accessible, and engaging learning environment. This may create time for exercising more complex skills during face-to-face training.

Project description:IntroductionNeonatal resuscitation is a team-based activity involving many decisions and tasks. Non-technical factors, such as teamwork, are increasingly recognized as impacting how well-neonatal resuscitation is performed, and therefore influencing infant outcomes. Prior studies on teamwork in neonatal resuscitation have focused on quantification of teamwork behaviors, or the effects of team training. This study aimed to explore healthcare providers' own perception of teamwork in this specialized environment to identify perceived barriers and facilitators to effective team functioning.MethodsThis single-center exploratory sequential mixed methods study used two phases. First, semi-structured interviews were conducted, and thematic analysis used to identify themes. Subsequently, interview data informed the development of quantitative surveys to explore selected themes in the wider team.ResultsFrom ten semi-structured interviews, seven themes were identified including: (1) Team Composition, (2) Effective Communication, (3) Team leadership, (4) Hierarchy, (5) Team Training, (6) Debriefing, and (7) Physical Environment. Perceived teamwork facilitators include role assignment, familiarity, team composition, talking out loud to maintain shared mental models, leadership, and team training. Perceived barriers included time pressures, ad hoc team, ineffective leadership, and space limitations. Selected themes (Communication, Speaking up, Hierarchy, and Leadership) were further explored via electronic surveys distributed via email to all members of the resuscitation team. There were 105 responses; a response rate of ~53%. All respondents agreed or strongly agreed that speaking up is important; however, not all felt comfortable doing so. Neonatal fellows (14%) and nurses (12%) were most likely to report not feeling comfortable speaking up. All respondents agreed that team communication is important to an effective resuscitation. Most respondents (91.5%) agreed that a hierarchy exists within the team; 54.3% believed that hierarchy positively contributes to effective resuscitation. All respondents agreed or strongly agreed that having a clearly defined leader is important in delivery room resuscitations. Ineffective leadership was the most cited reason for poor team communication.ConclusionsIn this mixed methods study of perceptions of teamwork within a specialized, multi-disciplinary neonatal resuscitation team, communication, hierarchy, and leadership were positively perceived and facilitates teamwork. However, even in this environment, some nurses and trainees expressed discomfort with speaking up.
