In short. Spreading redness, fever with chills, pus, increasing pain and a wound coming apart. What each means and how quickly to move.
Key points
- Emergency means the decision has already been made and the action is to travel.
- Same-day means the decision is made with your team and the action is to reach them and be seen today.
- If you cannot reach your team quickly and the finding is on the emergency list, do not keep trying — go to the nearest emergency department.
Knowing which findings can wait and which cannot is the whole of this subject, and the reasoning is short. It rests on three questions: is the process spreading, are you systemically unwell, and has the appearance of the wound changed?
The findings that mean emergency care now
Redness whose margin has advanced since it was last measured. A red line tracking up the limb from the wound. Fever with chills, shivering, or feeling generally very unwell. Skin around the wound that has turned dusky, blistered or black. Each of those indicates a process that is no longer confined to the wound, and each of them is a reason to attend the nearest emergency department rather than to wait for a reply from anyone. The urgency is not about how the wound looks. It is about where the process has reached.
Two lists, and the difference is who decides
Emergency means the decision has already been made and the action is to travel. Same-day means the decision is made with your team and the action is to reach them and be seen today. If you cannot reach your team quickly and the finding is on the emergency list, do not keep trying — go to the nearest emergency department. If the finding is on the same-day list and your team cannot be reached, call the hospital main line rather than waiting until the next day.
The findings that need to be seen the same day
Pus, or discharge that has become thick, yellow-green or foul-smelling. Increasing pain, heat and swelling after the first week, which is the opposite of what healing does. A wound that is opening, or stitches pulling through the skin. And a red, hot, tender area around an implant or an area of injected material, which is treated on a different set of rules because that tissue has no blood supply of its own. Each of those is seen the same day rather than observed at home.
What can wait for a review
A wound edge that is red but whose margin has not moved. A small amount of pale non-smelling discharge at suture points. Swelling and tightness that peaked early and are now reducing. Soreness that is settling. Those are the ordinary course and they are raised at a review or in a telephone call. The reason they can wait is not that they are trivial but that none of them is moving, and a process that is not moving is one that can be assessed calmly.
The emergency list
- Redness whose margin has advanced, or a red line tracking up a limb.
- Fever with chills, shivering, or feeling generally very unwell.
- Skin around the wound turning dusky, blistered or black.
The value of separating the lists is that it removes the judgement from the moment when judgement is hardest. A patient who knows that a spreading margin is a reason to travel, rather than a reason to make a call and wait, will act on it at the point when acting is worth the most.
Frequently asked questions
Which findings can wait?
A wound edge that is red but not advancing, a small amount of pale non-smelling discharge at suture points, swelling and tightness that peaked early and are reducing, and soreness that is settling. Those are ordinary healing. The absence of spread, the absence of fever and the absence of a change in discharge are what make them safe to raise at a review.
What is the difference between urgent and same-day?
Emergency care means going now, without waiting to speak to anyone: spreading redness, a red line up a limb, fever with chills, or skin that has turned dusky or black. Same-day means contacting the team and being seen today: pus or changing discharge, increasing pain and heat after the first week, a wound that is opening, or a red hot area around an implant.
What if I am not sure which one it is?
Describe the findings to your team and let them decide, and if you cannot reach them, call the hospital main line. Where the finding is a spreading margin, a red line or a fever with chills, go to the nearest emergency department rather than spending time trying to reach a particular person. The cost of being seen and told that nothing is wrong is a wasted journey.
Risks & Limitations
- Redness and warmth are the first stage of healing as well as the first sign of infection. Direction and speed decide the question, so a margin that advances over hours is the finding rather than the presence of redness.
- An infection that is spreading can move quickly. Spreading redness, a red line tracking up a limb, fever with chills, and skin turning dusky or black all need emergency care rather than a review appointment.
- An antibiotic has to match the organism. A course taken from a drawer, or one that is stopped early, treats the wrong cause or treats it inadequately and makes the next assessment harder.
- An implant has no blood supply of its own, so an infection beside it behaves differently and can be present with far less to see. It is seen the same day rather than watched.
- Where an infection needs an operation, the aim is to preserve tissue that is still viable and to end the infection. It cannot restore tissue that has already been destroyed.
- No assessment predicts an infection exactly, which is why the warning findings are taught to every patient rather than only to those at higher risk.
When to Seek Care
- Redness that is spreading outward, or a red line tracking up a limb &mdash — seek emergency care now.
- Fever with chills, shivering, or feeling generally very unwell &mdash — seek emergency care now.
- Skin around the wound turning dusky, blistered or black &mdash — seek emergency care now.
- Pus, or discharge that has become thick, yellow-green or foul-smelling — contact the team the same day.
- Increasing pain, heat and swelling after the first week, or a wound that is opening.
- A red, hot, tender area around an implant or an injected area.
