About charts

Nervecentre Charting allows you to view changes in a patient's data over time. Charts bring together different elements of patient care into a single view, so that you can understand the effect of your interventions. For example, you can view how your care has affected a patient's temperature, blood pressure, and other recorded observations over the past few days.

There are three types of chart:

  • Template charts

    You can use template charts for any patient. You can view the last 6 months of a patient's data up to the current time.

  • Pinned charts

    You can pin a template chart to create a pinned chart for a patient. A pinned chart shows a patient's data from a specific start time to the current time.

  • Archived charts

    You can archive a patient's pinned chart. An archived chart shows a patient's data from a specific start time to a specific end time.

About charts on a desktop

A chart is a group of widgets arranged in a specific order. A widget is a group of series. A series contains data from one or more data fields.

Below is a diagram of a chart.

The chart below shows how the patient's blood pressure, heart rate, central venous pressure, potassium levels, and response changed over time. It also shows the patient's IV of replacement potassium.

A chart is made of one or more widgets. This chart has three widgets.

A widget is made of one or more series. In this example:

  • The top widget shows four series: the patient's systolic blood pressure, diastolic blood pressure, heart rate, and central venous pressure (CVP).

  • The middle widget shows two series: an IV of replacement potassium, and the patient's potassium levels.

  • The bottom widget shows one series: the patient's response.

Each series in a widget displays data from one or more data fields.

You can display data in a series in:

  • A line graph

    In this example, blood pressure, heart rate, and potassium are four series shown on a line graph.

  • A table

    In this example, central venous pressure (CVP) is a series shown in a table.

  • Lanes

    In this example, the IV of replacement potassium is a series shown in a lane. A lane can have markers, time bars, and sub-lanes. You can collapse sub-lanes into a single lane.

  • A categorised graph

    In the bottom widget of this example, a patient's response is a series shown on a categorised graph. When a user records a set of observations, they can record if the patient is alert, in pain, or unresponsive.

  • A stacked bar chart

    This is only for series showing data for fluid balance.

A data field is an item in the Nervecentre database. For example ‘Heart Rate’, or ‘Haemoglobin’.

The Nervecentre database might contain data fields with similar names, but the data for each field comes from different sources. Each data field has a unique identifying code. For example, you might have two data fields for haemoglobin: one data field for haemoglobin results from lab tests, and another data field for haemoglobin results from blood gas analysers.

Depending on your permissions, you can create and edit series, which contain one or more data fields. When you are creating series, you must choose the data fields that contain the data you want to display. You can't edit data fields. You can add data fields to a series.

A series contains data from one or more data fields. A series can only contain one type of data field, for example, only observations, or only medications.

Depending on your permissions, you can add series to a widget, and display widgets on a chart. You can choose how to display the data in a series. For example, as a graph or table.

All series are shared between all users. Any changes to a series affects all charts that use the series.

A widget is a group of series. Series in a widget display in a specific order, and they can display differently to each other. For example, one series might display data as a line graph, and another series might display data in a table.

Widgets can be shared between charts. If a widget is not shared, it can only be used on that chart.

A template chart is a chart that is not patient-specific.

You can choose a template chart to view a patient's data in that chart. The chart shows the last 6 months of the patient's data.

Depending on your permissions, you can share a template chart with other users to allow them to access it. If you don't share a template chart, only the creator of the chart can access the chart.

Depending on your permissions, you can edit template charts. If you edit a template chart you own, you can save the changes for all users, or create a copy of the chart. If you edit a template chart you don't own, you can create a copy of the chart.

A pinned chart is a patient-specific chart that has a start date.

You can pin a template chart for a specific patient. All users can view that patient's pinned charts.

You can view a patient's data in a pinned chart. The chart shows data from the start date to the current date and time.

Depending on your permissions, you can edit pinned charts. When you edit a pinned chart, the changes only affect the chart for that specific patient. All users can see those changes.

An archived chart is a patient-specific chart that has a start date and end date.

You can archive a pinned chart for a specific patient. All users can view that patient's archived charts.

You can view a patient's data in an archived chart. The chart shows data from the start date to the end date.

Depending on your permissions, you can edit archived charts. When you edit an archived chart, the changes only affect the chart for that specific patient. All users can see those changes.
