Key Public Health Questions

Who needs to know and do what?

Use this step if you:

  • Know what injury area you are focusing on
  • Have sufficient data around the determinants
  • Know which determinants you want your intervention to address, and
  • Know the target audience, aims and objectives and activities of your intervention

This step is where basic project management concepts will be useful in actually implementing the activities that will help you achieve your objectives and ultimate aim.1

Planning an Intervention

Before you get to this stage it is assumed that you have already “designed” and “planned” your intervention.

You need to have defined the specific issue, target audience, the aim, objectives and the activities of your intervention before you reach this section.

Here we will briefly revisit some of the key concepts.

What are aims, objectives and activities?

Aim: An aim is a broad statement that relate to the improvement of a health condition in a population. This can be a change in mortality or morbidity rates, disability, quality of life or equity. Aims are achieved through a range of objectives.

Objective: Objectives are medium-term changes that you would like to see to help achieve your aim. Examples of this could be increased awareness or a change in policy, practice or environments. Activities undertaken to achieve these objectives are called activities.

Activities: Activities are short-term actions aimed at achieving an objective. Activities can include using print materials, online advertising, training workshops, peer support or a variety of other activities.

How will you achieve your aim, objectives and activities?

An action plan is the process that organises your activities into a sequence of tasks with defined timeframes, supported by a communication strategy.  The reason that it is important to develop an action plan is that it:

  • Enables the broad outline of the intervention to be converted into a actionable work plan
  • Ensures that the activities of the intervention are organised enough to help establish the sequence of activities
  • Ensures that there are clear roles and responsibilities of who will lead each activity
  • Ensures the necessary allocation of resources has occurred
  • Ensures risks are considered and mitigated
  • Ensures effective communication procedures are in place to monitor progress of the intervention.

How do I sequence my activities?

Gantt charts are one useful tool for sequencing you activities and tracking the timeline of your project, allowing for you to visually map when your intervention milestones are.

As has already been mentioned, partnerships can be a key element to implementing an effective intervention and maximising its potential impact. The implementation of a intervention should involve determining where partnerships or alliances can be used to greatest benefit in order to achieve your selected aims and objectives.

Question which can guide your decision making include:

  • What can/cannot your organisation influence?
  • With whom do you need to work?
  • What level of access does your organisation have to the target audience?

Further information about partnerships can be found here.



As mentioned in the Learn – Overview, sustainability is a crucial consideration in the implementation of an intervention.

Just like evaluation it needs to be considered at the planning and implementation stage of an intervention.

Sustainability refers to:

“The existence of structures and processes that allow an intervention to leverage resources to effectively implement and maintain evidence-based policies and activities.” 3

Sustainability needs to be considered both in terms of:

  • Sustainability assessment: assessing the value of continuing the intervention. This may involve determining whether or not the intervention should be discontinued, maintained or repeated. Answers to many of these questions is dependent upon the evaluation and monitoring activities undertaken for the intervention.
  • Sustainability planning: Once new interventions have been established to be effective there is often a process of incorporating or institutionalising them into existing organisations. This process requires planning to ensure the effective ongoing delivery of beneficial interventions.

A practical guide for the consideration and planning of sustainability factors has been developed by the US Center for Public Health Systems Science. The guide proposed by this organisation includes a three part sustainability planning process that allows for the consideration of sustainability issues during the planning and implementation stages.  The planning process includes the following:

Step one:        Understand the factors that influence intervention sustainability

Step two:        Complete a Intervention Assessment Tool

Step three:     Use the results from the assessment process to inform a sustainability action plan

Step four:       Implement the plan

It may be useful for you to think about completing the assessment and developing a sustainability action plan which can form part of your implementation of the intervention – so you are prepared for making the intervention sustainable in the longer term.
