Notación UpHill

Empieza a representar algoritmos hoy mismo


Una nueva forma de crear, leer y compartir vías clínicas

We know that each algorithm is unique. But why does their representation have to be different?

Inconsistencies in the representations raises subjectivity, hinder faster reading and compromises the adoption of clinical pathways.
This is our motivation to create a clinical universal language.
A solution to share and discuss clinical pathways in a clear, simple and consistent way:
  • Actions | Rectangle: activities to be made (requisitions, prescriptions, etc.);
  • Decisions | Diamond: moments of choice according to criteria and decision options;
  • Endings | Circle: Defines the patient's final status on a given path;
  • Connections | Arrows: to express the relationship and sequence between actions/decisions/ends.

With this notation I can represent algorithms in less than 2 hours. Rethinking the process and aligning the steps we make every day is a valuable asset.

How to begin?

Step by step guide to design a clinical pathway

Representing algorithms can be quite challenging. Expressing the complexity of the relations between each moment of decision, evaluation and even reflection is not always linear. That is why we have created UpHill Notation.
To start representing an algorithm, it is important to know the initial moment. Does the patient have a confirmed diagnosis? Or does he arrive with a suspicion? What are the inclusion and exclusion criteria? Defining this initial moment is crucial for a correct representation of the algorithm.

What should I do next?

After understanding the context of the algorithm to be represented, each moment must be sequentially framed. The purpose is to be able to express the relationship between actions, be it temporal or causal.


Activities to be made

Actions are all moments on the algorithm where an activity must be done. This category includes objective examinations, prescription of drugs and other therapeutic attitudes or the request for additional diagnostic tests.

How to put into practice

Let's consider the HFpEF algorithm:
“If the patient shows signs and symptoms of congestion, a Diuretic should be prescribed along with a Beta-Blocker and a ACE inhibitor/ARB”
“If the patient does not show signs and symptoms of congestion, only a Beta-Blocker and a ACE inhibitor/ARB should be prescribded”


Choosing moments

Decisions are all moments when a choice has to be made according to a criterion, whether is the patient's condition, signs and symptoms or clinical results.
Decision moments can have one or more options.
The maximum number of paths that can be followed is defined by the number inside the diamond shape. For example, if this number is “1” then only one of the paths can be choosed.
If the number is joined by a “+” it means that one or more paths can be taken.
In these moments of decision, a criterion can sometimes be applied, usually in the form of a question in which the answer to that criterion defines the path to be followed.
If there is no criterion, then the path is defined by itself.

How to put into practice

Let's consider the HFpEF algorithm
“If the patient has K +> 5.5 , still symptomatic and with LVEF <35%, an MRA must be prescribed. If the patient is not symptomatic and has LVEF <35%, then he is under control.”


Finalización de una ruta

Los finales son todos los momentos de finalización de un camino del algoritmo. Un final no es necesariamente el momento de finalización del algoritmo en sí, sino el final de un camino.
Todos los elementos del camino, acciones o decisiones, pueden terminar con un final. Cuando esto ocurre, el círculo debe ser seguido por el estado final del paciente para el camino respectivo.
Varias acciones o decisiones pueden tener el mismo final.
El mismo final puede ser compartido por diferentes acciones o decisiones, aunque ocurran en momentos o fases diferentes.


Conexiones entre elementos

Las conexiones son todas las relaciones expresadas entre elementos. Estas relaciones deben reflejar la secuencia, temporal y/o casual entre acciones, decisiones y finales.
Siempre que haya acciones repetidas a modo de ciclo, como las valoraciones de fármacos, estas trayectorias deben representarse con una línea discontinua.
Por ejemplo, si entre las acciones hay un criterio temporal que debe aplicarse, debe describirse encima de la flecha de conexión.
