In part I we covered Drug References, and now in the continuation of the WebOS Medical App Roundup, we deal with Calculators and non-drug References. As WebOS is relatively young, I think there is quite a lot of room for more useful apps in this area so it’s a golden opportunity for coders to get on the WebOS bandwagon, more so since Palm does not charge any Developer Access fee nor and fee to list your app in the Official App Catalog. Calculators are probably one of the most used medical apps and I am sure many of you would know of MedCalc which is the great software originally on PalmOS and Windows mobile and more recently also available on iPhone. So what equivalents do we have for WebOS so far?
Medical calculators and lab references
MediPDA started off in Precentral Homebrew and grew out of a personal need for medical calculators, in particular the two I use almost daily in my work, which are Body Surface Area and GFR calculations. I had a lot of help developing this app, in particular from Janni Kovacs (a talented programmer who has created lots of free WebOS apps – see his MojoJungle site) and some contribution from Neil Lall. When it was published in PreCentral Homebrew, it had about 10 modules and since then it has grown to over 30 modules. We have been adding more modules as suggestions and requests have continued to come in, and whenever time permits, I have been adding them slowly, and the last update, version 0.3.8, was just approved on July 10, 2010. At this point, MyAppBox records over 90,000 downloads for MediPDA, the average rating is 3.9/5. You can also get MediPDA in Homebrew which I think is still an important place for free apps since the App Catalog is not available to users outside of the “official” launch countries. Price: Totally Freeware.
Medical Palm users may recall an app called Haemoncrules for PalmOS which I developed (mainly out of a personal need ) and decided to release as freeware for medical users. OncoPDA is the WebOS reincarnation of Haemoncrules and was also developed with the help of Janni Kovacs. It is a rather niche app as it would be useful mainly for those in Hematology/Oncology but it will hopefully be beneficial to those in this area. I do use NHL IPI, FLIPI, MDS IPSS and WPSS on a very regular basis myself and hope others will find it useful. It is freeware and garnered some 600+ downloads but no ratings or comments yet! OncoPDA is also available in Precentral Homebrew .
Dose by J@ckPot Ideas is a medical dosage calculator “developed with the Nurse and Nursing student in mind”. The app will aid Nurses in performing Unit Conversions between mass units (mg, mcg etc) as well as calculate tablet and liquid Dosages, IV Drop Flow rate, Dosage by weight and Min / Max Safe Dosage range. I have not been able to review this app at this point in time but it has garnered some 1300 downloads and a rating of about 3/5. Dose is priced at $0.99 in the App Catalog.
Lab values by Vimukti Technologies is a WebOS reference app which stores normal values for about 150 common laboratory values used in medical practice. I can imagine it will come in handy if the lab report does not contain any normal values. We have not had the opportunity to review this application so we can’t say how much detail the app has for each normal value. According to the app description, it has a search function for fast access, something necessary as the database grows in size. Lab values for WebOS has garnered 600 + downloads to date and has a user rating of about 3/5. Price: $1.99
ChemConverter is an app which I developed out of a real need to perform unit conversion for laboratory values, something I face on a regular basis e.g. values for cholesterol in US to SI and vice versa. The app was coded entirely using Ares (Palm’s web based app development tool) and presents the items in a Filterable List view for fast access. Apart from performing the conversion the app also displays Normal values (therapeutic ranges in the case of drugs) as an added bonus, and also has links to sites where one can get more information on the specific laboratory test. The app was only launched in July 2010, and has garnered about 79 downloads so far with a user rating of about 4/5. The main feedback seems to be a desire for more lab test items and indeed I have been adding more on a regular basis. The latest version (1.4.8) should be out soon on the App Catalog and has 48 items. Price $0.99 in the App Catalog.
PreOpEval is a WebOS port of Josh Steinberg’s PreOpEval for the iPhone . It is basically a handy guide to help evaluate and prepare adult patients for non-cardiac surgery. I developed this using Ares as well and in doing so it was a learning exercise for me. I can say producing text guides like this is DEAD EASY using Ares and I can imagine more medical guides coming out for the WebOS platforms in due course. A future post in the Creating your own medical apps for WebOS series will deal with using Ares to make handy guides like this. The app has seen some 700+ downloads so far and a user rating of 4/5. Price: freeware
Carboplatin is an app I featured in Creating your own medical apps for WebOS (part 4) as an example (complete with source code) of how easy it is to create a medical app using Ares. It was actually created out of a request by an ObGyn colleague and I took it as another learning exercise in programming using Ares. The application is basically a dose calculator for Carboplatin using the Calvert formula. The app computes and displays dosages for actual, ideal and lean body weights. It has seen 600+ downloads since release but no comments or user rating yet. Price: freeware.
