Few days ago, I had posted about using IVR ( Interactive Voice Response) System in mission critical operation in underground mining operation. Continuing int he same line, there is another interesting IVR application which is useful in our day to day life and can prove to be life saving at times! That is IVR based automatic pill reminder service.

In short, automatic Pill reminder service is essentially an outbound IVR which is capable of dialing out programmed phone number of the patient at programmed time automatically without any manual intervention. When the call is connected, it will play a recorded message and then wait for confirmation whether the patient has taken the medicine or not. When the patient dos not respond the call or confirm the medicine taken, IVR will raise an alarm either by sending an email or SMS to medical staff responsible for the patient’s hospital so that some manual intervention can be taken immediately depending on the severity of the timely medicine!

This kind of automatic pill reminder service can be hosted or on premise IVR system. In India, Niche Tech Services (P) Ltd offers both on premise as well as hosted IVR based automatic pill reminder service.

Few essentials in pill reminder services are :-

1. It should support different language for different patients

The IVR should be able to play messages in different languages so that save IVR system could be used to alert many patients.

2. It should be be able to record response from patient

The pill reminder service should be able to accept some response either DTMF ( Dual Tone Multi Frequency) press or automatic speech recognition. Automatic Speech recognition ( ASR ) may work well since it will just need YES or NO response from the patient.

3. It should provide alarms

The IVR should be capable of raising an alarm to concerned doctor or medical supervisor responsible for the patient immediately if the patient fails to respond to the pill reminding call or respond about the medicine taken in negative. Timely intervention by a medical supervisor may prove to be life saving exercise at times.

4. It should have MIS

The system should be able to provide patient wise, call wise MIS ( management information system) so that complete medical history for the patient could be organised. It should also store all responses by the patient.

Having IVR based pill reminder system offers many benefits. For example, now a days everybody keeps a mobile phone with him all the time and always attentive to any call. So, alert system using a telephonic call has more chances of being attended.

Getting response and storing them is useful information for he doctor for analysing about the patient responsiveness to the treatment.

Using phone is one of the cheapest and better option that having any web based reminder system or alarm system. An IVR can precisely play a message about the type of medicine the patient is required to take at that time. This will help the patient to concentrate on his regular works having to remember about his medicines and worry about it all the time.

So, if you have a hospital or medical service facility, it is time you put automatic IVR based pill reminder system in place to serve your patients better! Even call centers can offer this service to many large hospitals and health care industries.

What is IVR customisation ?
Normally, an IVR application is designed and developed as per requirement of the customer by IVR companies. But they have ready-made modules tested and readily available for quick development. Normally, the modules like, telephone interface, ring detection, caller ID detection, database connectivity etc. are always readily available. Also many people use RAD tools for IVR customization where they simply implement call flow required by the customer. So IVR customising can be described as implementing call flow of the IVR application as desired by customer using existing IVR related software modules.

In fact, after RAD (Rapid Application Development) tools have been introduced, IVR development have become just IVR customisation. Many IVR functionality, modules are available in RAD tools ready-to-be-used. It is not easy to develop an IVR application from scratch, as it involves auxiliary knowledge and experience about telecommunication switches, telecommunication standards and protocols, speech recognition, TTS.

While RAD tools are easy and quickest way to developed customised IVR application, but it may not suitable for IVR customisation which needs to interact with existing business processes or existing software which generate various data to be provided by the IVR. For example weather update, complaint ticket generation, complaint status update etc. Apart from these kind of complex and very sophisticated IVR systems, RAD tools are excellent development or customisation tools for IVR solutions.

One important aspect which many people overlook is writing script of voice prompts and recording of voice prompts professionally. IVR systems are to be deployed to be used by normal people for availing services, solutions from it. IVR system interacts with its user ( caller to the IVR) through voice prompts. Any mistake in voice prompts may render the IVR useless. For example, if the voice prompts announces, “to know your complaint status, press 1, or press any key to end the call.” Now imagine if IVR is coded to recognize 1 for disconnecting the call and any other key for asking further information to retrieve complaint status!

So, while customising IVR application, one must write script for voice prompts and record them with professional voice artists. Without this, IVR system may have the best of the hardware and most well coded software, still IVR system will not be useful to its intended users.

While customising an IVR application, one should think about future enhancements. Many times, one finds out that existing codes can not be used for enhanced services, features and everything needs to be done from scratch. This not only delays the process of upgrading IVR systems, also it become costlier.

While integrating with third party application or software, direct interaction with their database should be avoided. If you do so, any changes made by them would require you to make changes in your code too. So I think HTTP URL is a very good approach where you send few parameters for exchanging data from third party application. This will ensure that your IVR code need not be changed even if third party database is changed.
