The ERres app is a resource that contains many of the most used calculators, decision rules, and medications that are used in the emergency care setting.

On their website, the app claims to contain evidence-based information that is constantly being updated. With continuous updates, the app was created to replace paperback versions of the same information so that healthcare workers do not have to keep purchasing new versions.

Previously, 10 Second EM used to be an app that every emergency medicine provider would have as a tool to reference.

However, the app and the information it contains has not been updated since October 2011.

There also does not seem to be any active development or plan for any updates in the near future. The ERres app may act as the best alternative to replace the current go-to app in the emergency medicine field.

User Interface

The app starts with a screen that lists the several categories of information that are covered. These categories include medications, trauma, calculators, etc. The main screen also has options for more information, a search function, bookmarks, personal notes, feedback and a share function.

The information page gives the user helpful tips on how to use the app. One of the tips states that by swiping to the left, the app will return to the main screen. Although this is a useful feature, it did not seem to work as I was reviewing the app and may be a bug that needs to be fixed. The app also claims to include evidence-based information that is continuously updated. However, this information could not be confirmed anywhere within the app and there are no citations or references included for any of the content.

Once a main category is selected, there is a list of subcategories that are presented to the user. After one of these subcategories is selected, the content of the app is presented. The content includes quick bullets of information that are very easy to digest on the go. The information can be great if used to refresh the user of key steps when working up a patient in the emergency care setting. The information also includes images such as examples of normal ultrasounds compared to an ultrasound that shows abdominal fluid or gallstones.

However, the content is presented as strings of several pages. It would be better if the subcategories were broken down further so the user could quickly skip to a specific section they are interested in rather than scrolling past pages of bulleted information.

A useful feature that this app has is the ability to bookmark pages within the app. This is useful if there is certain content that a user may reference frequently such as specific calculators. The app also has the feature of adding personal notes into the app. However, the notes are only saved on the main screen and cannot be added to the pages of specific content, making the feature less useful..

Price

  • $4.99 for iOS, $2.99 for Android

Likes

  • The app includes bulleted information that is easy to digest
  • The app includes images of normal and abnormal ultrasound results

Dislikes

  • Does not allow the user to add notes to specific content
  • The content is displayed as several pages that the user has to scroll through to get to the sections they want to use
  • Does not list where the evidence-based information is taken from.

Healthcare workers that would benefit from the app

  • Any healthcare worker who has a role in an emergency care setting can benefit from this app.

Conclusion

  • Overall, this app has content that can be useful for healthcare workers who work in an emergency room. The information is presented in an easy to understand format and can be great for medical students, residents, nurses and physicians.
  • However, there are no references to the information within this app although the information is claimed to be evidence-based.
  • This app needs to include PubMed or dosing references to actually be considered a legitimate source for healthcare workers to use. This is unlike the 10 Second EM app which has references listed throughout the app. The app also could improve the user interface by making it easier for users to get to the information they want rather than scrolling through pages of other text.

Rating: (1 to 5 stars): 3/5

  1. User Interface: 2/5 – The information is presented as pages of bulleted information. This can be annoying to use if the user needs to access information towards the end of the section and has to scroll all the way down while trying to find the information they want. It would be better if the sections were broken down further. Also, the app does not allow the user to add notes to specific sections.
  2. Multimedia usage: 4/5 – The app includes several images of ultrasound findings, both normal and abnormal which can be helpful.
  3. Price: 4/5 – The price is different for both Android and iOS. If the information is evidence-based and changes continuously as the app’s websites states, it is a great replacement for the current paperback versions of the same information.
  4. Real world applicability: 2/5 – Currently, with no references within the app, the app cannot be used to help make any clinical decisions. The app can only be used by users to help guide their thought process while working up a patient.
