CMLTO Professional Development Activities
Effie Lau, BSc, MLT
Professional Coordinator – Quality Assurance, College of Medical Laboratory Technologists of Ontario (CMLTO)
On January 1, 2021, the CMLTO launched its updated Quality Assurance Program (QAP) which includes the Stage 1 and Stage 2 Professional Portfolio. Practising registrants are required to maintain an up-to-date Professional Portfolio each year. All Practising registrants submit their Stage 1 Portfolio by March 31st of each year, and those randomly selected for audit must submit their Stage 2 Portfolio, including their Professional Development (PD) activities, for review by QAP staff by December 31st.
What can I claim for my PD hours?
As Medical Laboratory Technologists (MLTs), we all understand the importance of maintaining and enhancing our professional practice. Therefore, the CMLTO believes that PD occurs from any activity that advances an MLT’s knowledge, skill, or judgment to provide better, higher quality services within their practice setting. After you have completed an activity, you should ask yourself, “what did I learn and how can/could I apply these learnings in my MLT practice?” If you can clearly answer this question, the activity may be claimed in your Professional Portfolio.
How do I record my PD activities?
The PD section is found in the Stage 2 Professional Portfolio. There are three requirements:
In the Key Learnings section of each activity, you will record the answer to the question above, “what did I learn and how can I apply these learnings in my MLT practice?” For example, if you reviewed a transfusion guideline and it advanced your MLT knowledge, you may claim that activity. If the activity is linked to a goal, you record how it enabled you to advance your goal in the Impact on Practice section.
To assist MLTs, the CMLTO developed a Self-Directed PD Guideline on the maximum amount of hours that MLTs can claim for certain activities (here). If you have any questions about your Professional Portfolio, please contact the QAP department at 1-800-323-9627, extension 2, or by email at firstname.lastname@example.org.

Hemorrhage is the leading cause of preventable death within the first 24 hours after trauma in children and adults. In May 2021, the Ontario Regional Blood Coordinating Network (ORBCoN) disseminated the first provincial pediatric and adult evidence-based massive-hemorrhage-protocol (MHP) and associated toolkit content including recommendations for 8 quality improvement (QI) metrics.1,2 The initial QI data have provided insight on MHP trends in Ontario hospitals, and highlighted differences between adult and pediatric MHP activations.
MHP activation data and 28 day follow-up from 8 Ontario hospitals including 2 pediatric tertiary care centers was retrospectively collected (January 2019-May 2022). Patient demographics, mortality rates and 8 MHP QI metrics were entered in REDCap© data-collection-tool, and differences between adult versus pediatric MHP quality metrics were assessed.
In total, 363 MHP activations were reported and available for comparison (44 pediatric, 319 adult) (Table 1). Hemorrhage from traumatic injury accounted for most activations in children (59%) and adults (40%). Analysis of the QI metrics (Table 2) showed children were more likely to experience MHP over-activation (66 vs. 39%, p=0.002; correct activation defined as blood component requirements of adults>6 RBC units; children> 40 ml/kg, or death due to bleeding within first 24-hours) and less likely to experience a delay in RBC transfusion (4.5 vs 13%, p=0.003 (defined as > 15 minutes from protocol activation). Both cohorts reported ≥ 20% of patients had delayed tranexamic acid (TXA) administration and both cohorts had 11% of patients with uncorrected hypothermia at MHP termination. RBC over-transfusion (Hgb>110 g/L at MHP termination) was common and reported in 45% and 31% of children and adults, respectively, and 9.1% and 16% in children and adults reported blood component wastage.
MHP over-activation was more common in children compared with adults, with pediatric patients tending to see more unecessary activations as well as over-transfusions. One possible explanation is that hemorrhagic shock in pediatric patients may have a delayed onset or be more challenging to diagnose. However, these concerns should be balanced against transfusion risks, including hyperkalemia, hypoglycemia, and circulatory overload. In both cohorts, timely administration of TXA and management of hypothermia should be improved, as both have been shown to improve mortality in hemorrhage.
One limitation of this analysis is low numbers of pediatric MHP activations. However, at the time of this newsletter publication, there will be approximately 1700 MHP activations collected in the RedCAP® system, around 100 of which are expected to be pediatric activations. The data analysis is ongoing. The MHP QI metrics system is a valuable tool to identify the areas of improvement, with an overall goal of improving outcomes in patients receiving MHP.
