Data extraction

General characteristics: What are the general characteristics of resources which describe options to improve transitions?
Year of publication
Country: If multinational use corresponding author affiliation
Condition: Targeted neurodevelopmental condition
Definition of transition: What did 'transition' mean to the authors of the paper?
Age of transition: What ages did ‘transition’ mean to the authors of the paper?
Question 1: Tools/strategies: What tools/strategies to improve the transitions have been described?
This section is to capture key ideas (if commentary) or the intervention trialled (if implemented) to cover a wide range of options which may aid in transitions.
Summary of tools/strategies (Free text)
A broad summary about tools or intervention
How do the tools/strategies cluster together into similar approaches (eg, education, paperwork, clinics, new staff)?
People
Which groups of people need to provide time or resources for this tool/strategy to work? (Choose all that apply)
Setting
Does the tool/strategy require a clinical environment to be implemented? (Yes/No)
Would this tool/strategy need things at a clinic? (eg, are there specific assessments done as part of this or could you imagine this happening at a community centre?)
Question 2: Patient-centredness: Were tools/strategies collaboratively designed and implemented with the diverse patients who experience these transitions?
Were the tools or strategies collaboratively designed (codesigned) with those impacted by neurodevelopmental disorders? (yes/no)
If so, how? (free text)
Were ethnicity or cultural aspects of care considered in the design and implementation of these tools or strategies? (yes/no)
If so, how? (free text)
Question 3: Implementation and evaluation: In cases where these tools or strategies are implemented, how effective were they in aiding transition?
For part A, ‘implementation’ we will include only the subset of papers describing tools/strategies which were tried by at least a single participant
For part B, ‘evaluation’, we will include only the subset which were both implemented (had at least on participant) and evaluated (included a comparison)
This section will not include and evaluation of bias or quality (as in a systematic review), but rather help to understand author insights and provide some guidance for options worth pursuing or not
Part A
(Only studies for which the tool/strategy was implemented)
Study participants
Who is involved as participants? (select all that apply)
Participant age
If patients are the participants, what is the age range of these youth? (minimum to maximum in years)
Participant number
Use those who completed the study, if more than one group, include all
Authors reflections about tool/strategy (free text) what worked, what did not, and what insights did they offer for improving services
Part B
(Only studies for which the tool/strategy was evaluated)
Was there a pre-post comparison (yes/no)
   Outcome #1 (pre-post):
   If yes, what was the outcome measure? (free text)
   Did the pre-post analysis with this outcome suggest the tool/strategy was effective? (yes, no, inconclusive)
Allow for recording of up to five different pre/post outcomes
Was there a parallel comparison? (yes/no)
Outcome #1 (parallel):
If yes, what was the comparison arm? (free text)
If yes, what was the outcome measure? (free text)
Did the parallel analysis with this outcome suggest the tool/strategy was effective? (yes, no, inconclusive)
Allow for recording of up to five different parallel comparison outcomes
Was there an evaluation without a comparator? (yes/no)
If yes, what was the outcome measure? (free text)
Did the evaluation suggest the tool/strategy was effective? (yes, no, inconclusive)
Allow for recording of up to five different outcomes without comparators
