Follow-up on
a previous article about DECT versus WIFI in healthcare.
What are the main criteria for going for WIFI?- Lower communication cost
- Wireless care registration
- Wireless flexibility needed
- Hardware flexibility needed
- Communication flexibility needed
Lower communication costIf your telephony costs are skyhigh, WIFI can surely lower them. Especially in situations with subsidiaries and international communication. VOIP-solutions are
evolving rapidly, your organization and your customers will benefit from that evolution.
Wireless care registrationI can't see any reason why you should not switch to VoWIFI if you have already chosen for wireless care registration. Alternatively one could also state that one should
not choose for WIFI if you are
not going to implement
wireless care registration. I would go for wireless registration because of the improved customer service and because of the lower labor time and stress. Scrupulous vendors will subsequently not hesitate to argue that, if you do not choose for WIFI, your organization is not patient-centered or employee-friendly.
Wireless flexibility neededLot's of changes in your building, rooms with different functions, flexible workstations, ... lots of cabling continuously needs to get moved?
Hardware flexibility (connectivity) neededNeed to couple WIFI-enabled devices and streaming audio/video? Need the freedom of choice in choosing (different) WIFI-devices from different manufacturers (Nintendo anyone)? Need to trace devices/stock/people (cfr. RFid and such)? Need to couple devices with extensive features like camera, digital pens, bluetooth and iR? WIFI can offer these convenient possibilities and offer a tailor made solution.
Communication flexibility neededMore efficient handling of calls, more possibilities to route communication to email, SMS, web, ... Coupling webtechnology is native. More choice in software solutions. WIFI is not a propriety system like DECT.
Hey, you left out "internet for customers"!Internet for customers also offers extra headaches for security, QOS, bandwidth, configuration, invoicing and paperwork. And what about concurrent users in central parts of the building, will they encounter the bottle neck on the transmitters? There are too many hidden costs in this service. I suppose that customers/patients who really want to be online continuously already have a wireless subscription of some kind. I don't think this to be an completely pro-argument as this service has many contra's as well.
What about improved team-communication?Sure, (unified-)messaging, limitless routing possibilities of data, availability of data, design (userfriendly visualizations) will enhance communication and productivity.
But beware of
userfriendlyness of the tools and technicality of the applications. In the "ideal" situation the cellphone/PDA should handle: voice, messages, alarms and care registration (I even leave out other functionality). I haven't seen one solution yet that doesn't require employee training. Technicality might be a big cost, technicality might be the cause of faulty registration or interpretation. I would suggest taking some of your staff to a demo and let them respond voice-calls and handle alarms
without training or instructions, let them think, observe how they do.
Doubts taken away:- Quality of voice-calls is impeccable.
- Handover (going from one transmitter to another) is seamless
- Transmission is secure. I checked 3 manuals and all could provide strong security (reminder: stay away from basic WEP or easy WPA-PSK passphrases)
- I can't say I experienced interference. But I haven't really tested that item thoroughly. Otherwise I can't imagine that interference could be an issue, because WIFI solutions have been widespread in different offices.
- I still haven't got a 100% guarantee that no alarms (like fire) will be lost. But such doubt could be cleared within a SLA.
Calculating WIFI ROI in a healthcare setting- Write down a description of current call- and care-handling in a IF -> THEN way, followed by the needed time to perform that handling.
- Write down the ideal handling of call- and care-handling. See what you can improve. Brainstorm with your staff. Write down the findings. Compare times.
- Now talk your findings over with two or three WIFI-companies. Check feasibility, ask for further improvement. Make final comparison of times for handling.
- Compare hardware costs.
- Compare calling costs.
Frustrating in this exercise is that there is no way you can quantify the convenience of flexibility. It is certain that your initial hardware investments will be
higher. It is also certain that your future investments and communication costs will be
lower (compared to DECT). WIFI-receiving devices are more mainstream, cost is definitely lower.
Uncertain is how much you will actually save because of the future freedom in choosing the best possible solution for your organization.
Clarification: I do NOT want to cut labor time because I want to lay off staff. Cutting time is essential in allowing care-staff to spend more time on the patient/customer ... instead of loosing time with old-fashioned communication. Lowering labor time and stress in healthcare is a
major issue. Also frustrating is the fact that it is nearly impossible to compare current and future employee absence caused by stress. You have to rely on your gut feeling here.
Hidden costs- Employee training needed for working with devices.
- Employee time lost by devices that are not userfriendly.
- Power consumption of the devices (more transmitters + more devices + more battery charging)
- WIFI technology is newer, you need more specialized and trained experts. This will result in greater costs
WIFI touchscreen questionsI'm on a quest for a basic wall-mounted touchscreen with identification, browser, onscreen keyboard and WIFI. I already had contacts with
Panasonic and
Mobilevision but the cost of those devices might be too steep for use in elderly care (about 2.000,00 EUR/piece).
Onboard sound (speakers or headphone in) is a plus, power consumption and absence of moving parts (like ventilation) are very important features.
Such touchscreens could be easy-to-use care-registration and care-consulting devices in homes for the elderly and service-flats. They should be installed in every room, price is essential (read: low). In my humble opinion the screens of domotics, Blackberrys or even PDA's are way too small and do not offer a decent solution for interaction (FTR: SMS on a 12 button phone is not a decent way to interact!).
Maybe the cost could be lowered by a using a fingerprint protected USB-stick with a
small operating system on it.
Might also write Nintendo for a more ruggedized version of the
Nintendo DS Light for care registration in healthcare.
