[Histonet] LIS questions

William, you bring up a very good point, but I”d like to respond to your
concerns this way:


1.        I don’t know how my online banking security works, but It does.  I
have to believe that the industry and ‘cloud based’ LIS vendors have already
solved this issue or that they will in the short term. Perhaps I am naïve in
where I place my trust, but the ‘cloud’ is such a big marketing thrust these
days, I have to believe that momentum alone will carry this forward.

2.       I guess I’m more of a functionality person than a technical person
though I do have a technical degree from a pretty decent school.  There are
so many perspectives to this issue that I am content to confine the current
thoughts to mostly functionality versus technical or legal.  Still, I always
try to be open to other thoughts and your commentary did just that – thank

3.       Finally, I think this topic is relevant to histonet because I’m
hearing more and more LIS vendors differentiate themselves as cloud vs
server based solutions.  Since I think the LIS will play more of a role in
the daily lives of histotechnologists, I think it’s a good idea to talk
about this and leave some trail of discovery for future people interested in
this topic.

When we start talking about the issues associated w/ server vs. cloud in
healthcare, I think discussion needs to start w/ and be centered on
capability of compliance and enforcement, as it relates to HITECH Act, HIPPA
and delivery of ePHI. There is a complexity added as more health information
exchanges are developed and access to data is expanded and the need to
develop complex and sound Business Associate Agreements.  In my mind, the
idea of more access and/or ease of access must be directly related to the
ability to control and provide security of access.
I believe this very complex issue and process will rely less on the needs of
the end user, Histotechnicians/Histotechnologists and more on the need to
meet HITECH requirements and very secure delivery. This is a very complex IT
issue and maybe not best discussed on the Histonet w/ technical personnel
with limited IT knowledge.

> internally, not across the world web.
> 3. We know this model works in both low and large volume operations.

> 1. You’re responsible for maintaining the server – operating system
> patches which occur every few months it seems and daily backups.
> 2. Cost associated with the server(s) – Often times there will be 2
> servers – production and development, plus there is a license fee. Bottom
> line, think around 10, 000 to 20,000. You also need a ‘place’ to put the
> servers.
> Cloud
> Pros:
> 1. A user can get to the system from everywhere -- great if you don’t
> have an infrastructure already in place.
> 2. No hardware costs for the server, but I would imagine that there is
> some fee hidden somewhere – nothing in life is free, right?
> Cons:
> 1. No control over your data. It can reside anywhere in the world and
