History Taking / Screening
Obtaining a patient’s history is the first critical step in determining the patient’s illness. Most of the times, a good doctor swears by the fact, that a good history would be enough to make a good diagnosis, if not decrease the number of differential diagnoses. In medicine, a differential diagnosis diagnoses is the process of distinguishing one disease from the other. A doctor uses this technique to identify a disease to be diagnosed or more importantly to eliminate life threatening conditions, especially when one symptom(s) are a part of several diseases. While not exactly arbitrary, broadly this exercise can be quite subjective and hence the emphasis on a protocol or evidence based approach toward diagnosis.

For what has the patient come to the clinic? Sometimes the patient may identify two or more conditions that they may wish to address. When this happens use the checklist in detail for each of the complaints.

In Digital health platforms, the task of history taking is shifted to the CHWs (Community Health Workers). The Thus the value of history taking of course will depend on the CHW’s ability to elicit relevant information.
At Intelehealth we have the required tools (clinical protocols) that will allow the CHW to obtain a relevant and detailed history via app prompts and we also train the CHWs periodically on newer updates or best practice procedures they can implement on the ground . The Hx Guide is a clinical history taking protocol and is akin to a checklist. It is set of instructions or guidelines on what should be the next logical step, in this instance, what relevant detailed history should be inquired into.
On the Intelehealth app platform, the clinical protocols are developed in a way that allows us to approach the patient’s concerns in a patient centered and problem oriented fashion. The patient initiates the Hx guide by describing a symptom. There are a total of 71 history taking protocols. The CHW enters the common condition as presented by the patient and as per the prompts from the app continues to take the history further taking a complete detailed history. An example (Building a hypertension protocol) is present in the link here.
Here’s an example of a CHW taking history using the Intelehealth app’s Hx Guide .
