Expertise Redundancy, Transactive Memory, and Team Performance in Interdisciplinary Care Teams.

ABSTRACT: OBJECTIVE:To examine how expertise redundancy and transactive memory (TM) in interdisciplinary care teams (ICTs) are related to team performance. DATA SOURCES/STUDY SETTING:Survey and administrative data were collected from 26 interdisciplinary mental health teams. STUDY DESIGN:The study used a longitudinal, observational design. Independent variables were measured at baseline, 6, and 12 months: expertise redundancy (the extent to which team members possess highly overlapping knowledge), TM accuracy (the extent to which team members accurately recognize experts in relevant knowledge domains), and TM consensus (the extent to which team members agree on who is expert in which knowledge domain). Team performance was measured as risk-adjusted average number of client hospitalization for the 6 months following each survey. DATA COLLECTION METHODS:Survey data were collected by the authors. Administrative data were collected by the state's administrative agency. PRINCIPAL FINDINGS:Expertise redundancy had a negative effect on performance. TM accuracy had a positive effect on performance, and such effect was stronger when expertise redundancy was higher. No significant effect was found on TM consensus. CONCLUSIONS:Transactive memory could serve as a cognitive coordination mechanism for mitigating the negative effect of complex knowledge structure in ICTs.

Project description:BackgroundWhen working in complex environments with critically ill patients, team performance is influenced by situation awareness in teams. Moreover, improved situation awareness in the teams will probably improve team and task performance. The aim of this study is to evaluate an educational programme on situation awareness for interprofessional teams at the intensive care units using team and task performance as outcomes.MethodTwenty interprofessional teams from the northern part of Sweden participated in this randomized controlled intervention study conducted in situ in two intensive care units. The study was based on three cases (cases 0, 1 and 2) with patients in a critical situation. The intervention group (n = 11) participated in a two-hour educational programme in situation awareness, including theory, practice, and reflection, while the control group (n = 9) performed the training without education in situation awareness. The outcomes were team performance (TEAM instrument), task performance (ABCDE checklist) and situation awareness (Situation Awareness Global Assessment Technique (SAGAT)). Generalized estimating equation were used to analyse the changes from case 0 to case 2, and from case 1 to case 2.ResultsEducation in situation awareness in the intervention group improved TEAM leadership (p = 0.003), TEAM task management (p = 0.018) and TEAM total (p = 0.030) when comparing cases 1 and 2; these significant improvements were not found in the control group. No significant differences were observed in the SAGAT or the ABCDE checklist.ConclusionsThis intervention study shows that a 2-h education in situation awareness improved parts of team performance in an acute care situation. Team leadership and task management improved in the intervention group, which may indicate that the one or several of the components in situation awareness (perception, comprehension and projection) were improved. However, in the present study this potential increase in situation awareness was not detected with SAGAT. Further research is needed to evaluate how educational programs can be used to increase situation awareness in interprofessional ICU teams and to establish which components that are essential in these programs.Trial registrationThis randomized controlled trial was not registered as it does not report the results of health outcomes after a health care intervention on human participants.

Project description:IntroductionVacuum extraction is generally considered an operator-dependent task, with most attention directed toward the obstetrician's technical abilities (1-3). Little is known about the effect of the team and non-technical skills on clinical outcomes in vacuum-assisted delivery. This study aimed to investigate whether the non-technical skills of obstetricians were correlated with their level of clinical performance via the analysis of video recordings of teams conducting actual vacuum extractions.MethodsWe installed between two or three video cameras in each delivery room at Aarhus University Hospital and Horsens Regional Hospital and obtained 60 videos of teams managing vacuum extraction. Appropriate consent was obtained. Two raters carefully reviewed the videos and assessed the teams' non-technical skills using the Assessment of Obstetric Team Performance (AOTP) checklist, rating all items on a Likert scale score from 1 to 5 (1 = poor; 3 = average; and 5 = excellent). This resulted in a total score ranging from 18 to 90. Two different raters independently assessed the teams' clinical performance (adherence to clinical guidelines) using the TeamOBS-Vacuum-Assisted Delivery (VAD) checklist, rating each item (0 = not done, 1 = done incorrectly; and 2 = done correctly). This resulted in a total score with the following ranges (low clinical performance: 0-59; average: 60-84; and high: 85-100). Interrater agreement was analyzed using intraclass correlation (ICC), and the risk of high or low clinical performance was analyzed on a logit scale to meet the assumption of normality.ResultsTeams that received excellent non-technical scores had an 81% probability of achieving high clinical performance, whereas this probability was only 12% among teams with average non-technical scores (p < 0.001). Teams with a high clinical performance often had excellent behavior in the non-technical items of "team interaction," "anticipation," "avoidance fixation," and "focused communication." Teams with a low or average clinical performance often neglected to consider analgesia, had delayed abandonment of the attempted vaginal delivery and insufficient use of appropriate fetal monitoring. Interrater reliability was high for both rater-teams, with an ICC for the non-technical skills of 0.83 (95% confidence interval [CI]: 0.71-0.88) and 0.84 for the clinical performance (95% CI: 0.74-0.90).ConclusionAlthough assisted vaginal delivery by vacuum extraction is generally considered to be an operator-dependent task, our findings suggest that teamwork and effective team interaction play crucial roles in achieving high clinical performance. Teamwork helped the consultant anticipate the next step, avoid fixation, ensure adequate analgesia, and maintain thorough fetal monitoring during delivery.

Project description:AimThe aim of the study was to describe practices that support collaboration in interprofessional primary health care teams, and identify performance indicators perceived to measure the impact of this collaboration from the perspective of interprofessional health providers.BackgroundDespite the surge of interprofessional primary health care models implemented across Canada, there is little evidence as to whether or not the intended outcomes of primary health care teams have been achieved. Part of the challenge is determining the most appropriate measures that can demonstrate the value of collaborative care. To date, little remains known about performance measurement from the providers contributing to the collaborative care process in interprofessional primary care teams. Having providers from a range of disciplinary backgrounds assist in the development of performance measures can help identify measures most relevant to demonstrate the value of collaborative care on the intended outcomes of interprofessional primary care models.MethodsA qualitative study; part of a larger mixed methods developmental evaluation to examine performance measurement in interprofessional primary health care teams. A stakeholder workshop was conducted at an annual association meeting of interprofessional primary health care teams in the province of Ontario, Canada. Six questions guided the workshop groups and participant responses were documented on worksheets and flip charts. All responses were collected and entered verbatim into a word document. Qualitative analytic strategies were applied to each question.FindingsA total of 283 primary health care providers from 14 health professions working in interprofessional primary health care teams participated. Top three elements of interprofessional collaboration (total n = 628) were communication (n = 146), co-treatment (n = 112) and patient-based conferences (n = 81). Top three performance indicators currently used to demonstrate the value of interprofessional collaboration (total n = 241) were patient experience (n = 71), patient health status (n = 35) and within team referrals (n = 30).

Project description:Effective delivery of healthcare is highly interdependent within and between interprofessional (IP) care teams and the patients they serve. This is particularly true for complex health conditions such as advanced heart failure (AHF). Our Academic Practice Partnership received funding to carry out IP workforce development with inpatient AHF care teams. Our objectives were to (a) identify challenges in team functioning that affected communication and relationships among the AHF care teams, (b) collaboratively identify a focal work process in need of improvement, and (c) test whether facilitated the implementation of team training and work process changes would lead to improvements in team communication, relationships, and process outcomes. The health-care team identified implementation of structured IP bedside rounds (SIBR) as the preferred approach to improving collaborative care. Utilizing a cross-sectional pre/post design, changes in team communication and relationships before and after a team intervention that included TeamSTEPPS training and SIBR implementation, were assessed using a validated Relational Coordination (RC) survey. The study population included AHF care team members (n ~ 100) representing seven workgroups (e.g., nurses, pharmacists) from two inpatient cardiology units at a 450-bed academic medical center in the Pacific Northwest during 2015-2016. Improvements in RC scores were demonstrated across all seven RC dimensions from baseline (Year 1) to follow-up (Year 2). Percent change on each of the seven dimensions ranged from 3.57% to 9.85%. Changes were statistically significant for improvements between baseline and follow-up on all but one of the seven RC dimensions (shared knowledge). The IP team intervention was associated with improvements in RC from baseline to follow-up. Additional research is needed to assess patient perspectives and outcomes of the IP team intervention. Findings of this study are consistent with the growing body of RC and SIBR research and provide a useful model of an IP team-based intervention in clinical practice.
