Latent class growth analysis is a popular approach to identify underlying subpopulations. Several implementations, such as LCGA (Mplus), Proc Traj (SAS) and lcmm (R) are specially designed for this purpose. Motivated by data collection of psychological instruments over time in a large North American cancer centre, we compare these implementations using various simulated Edmonton Symptom Assessment System revised (ESAS-r) scores, an ordinal outcome from 0 to 10, as well as the real data consisting of more than 20,000 patients. We found that Mplus and lcmm lead to high correct classification rate, but Proc Traj over estimated the number of classes and failed to converge. While Mplus is computationally faster than lcmm, it does not allow more than 10 levels. We therefore suggest first analyzing data on the ordinal scale using lcmm. If computational time becomes an issue, then one can group the scores into categories and implement them in Mplus.

A tertiary teaching hospital in Toronto, Canada, implemented a proactive team-based intervention to prevent burnout and support the mental health of health care workers., Summary There is an urgent need for institutionally integrated approaches to prevent burnout and support the mental health of health care workers (HCWs) during the Covid-19 pandemic and on an ongoing basis. The Princess Margaret Cancer Centre, a tertiary teaching hospital, developed and implemented CREATE—Compassion, REsilience And TEam-building. CREATE is a proactive team-based support intervention delivered at the point of care by psychosocial coaches (PSCs) to multidisciplinary frontline and oncology teams. Quantitative administrative data and qualitative process data were recorded by PSCs during the first pandemic wave from March 27 to June 19, 2020. Thirteen PSCs and clinical managers were paired to support 27 HCW teams. HCW team needs that were addressed by PSCs were categorized into four themes: (1) physical (14.5%), (2) social (28.4%), (3) psychological (46.2%), and (4) spiritual (10.9%). The emotional tone expressed within the teams became more positive over time, suggesting a reduction in team-level distress and an increase in team resilience. CREATE was perceived as valuable by PSCs, HCWs, and hospital leadership. This team-based approach can be rapidly adopted and delivered by other institutions during Covid-19 and applied to future pandemics.
