What We Do

2005-01-29T06:14:00.000-08:00

Medelis offers equipment consultancy, planning and inspection services to architects, consulting engineers, construction companies, healthcare management and healthcare providers.

We are entirely independent and have no financial or commercial connection with any manufacturer or supplier. Neither do we supply equipment or act as an agent for any product.

The range of services offered new hospital projects would typically include:-

1) Feasibility studies, including consideration of viability, initial budgeting, staffing requirements etc.

2) Assisting architects with overall hospital and departmental fundamental designs.

3) Room-by-room consideration of equipment requirements, based on current practice and the specific needs of the client.

4) Detailed budgeting and the perceived effect of change on present and future requirements.

5) Development of bills of quantities and equipment specifications to achieve a "best buy" for the client.

6) Production of tender documents, room-by-room listings etc.

7) Production of layout drawings, typically at 1:50 scale, showing equipment positions.

8) Planning of equipment installation and utilities requirements.

9) Detailed review of contractors' proposals and submittals (for conformance with contractual requirements etc.).

10) Liaison with suppliers on detailed layout, services and installation requirements.

11) Inspection of equipment arriving at site. Checks for damage, completeness, functionality and conformance with approvals.

12) Supervision of placement, installation, commissioning and handover of equipment at site.

13) Final inspection of installed equipment and acceptance on behalf of the client.

14) Review and checking the compilation of equipment operating and maintenance documentation.

Services for existing facilities can include:-

1) Condition surveys and valuation of existing equipment.

2) Advising on equipment upgrading, refurbishment, maintenance etc.

3) Planning and implementation of maintenance schemes.

4) Spare parts planning ... etc.

Nearing Completion

2005-01-28T06:18:00.000-08:00

The Art of Medical Equipment Consultancy

2005-01-27T06:23:00.000-08:00

1) The challenge is to establish what the client really wants!

2) Four factors define a project:-

Scope
Budget
Time Schedule
Desired Quality

The consultant must retain influence over at least the last named of these to avoid an endless battle for control of the work.

3) A hospital is a building where the sick, victims of trauma, and the physically indisposed seek cure, repair, relief and comfort. It should not be just another "monument to engineers and architects"!

4) The whole point of the exercise is healthcare - meaning "positive patient outcomes". Continually ask the question "How will this benefit the patient"?

5) This is a business too serious to be left in the hands of "experts" such as architects or doctors!

6) The hospital should be regarded as a system for the delivery of services aimed at bringing patients to full health. Patients are cared for by nurses, not beds! We are dealing with:-

The delivery of health services
Health services are about people
Delivered to people by people

7) The role of the architect and engineer is to provide an environment in which people can deliver health services to people in need; that environment should be:-

Safe
Functional
Comfortable
Pleasant

... in that order

8) What seems clever now may not seem so in ten years time. We seek simplicity, utility and function. Remember (as Mies van de Rohe quite rightly said), often "less is more"!

9) Mechanical and electrical services are provided to bring required services to the places where they are needed to deliver healthcare.

10) The consultant should think like a consultant, not a technician. He should always consider added-value for the client.

11) Always bear in mind the three goals of medicine:-

To cure sometimes
To relieve often
To comfort always

12) Clinical conditions must prevail! But, "Primum non nocere" (first, do no harm!).

Managing and Problem Solving

2005-01-26T06:26:00.000-08:00

"An Engineer is someone who can do for a dollar what any damn fool can do for ten!"

When facing a crisis

1) Identify the problem (really identify it; define it, write it down)
2) Focus all attention on it
3) Solve it
4) Then leave it alone (don't "tinker" with it)

Real objectives

1) What's the objective?
2) Is it profitable?
3) Is it clear?
4) Is the proposition attainable and practical?
5) Is the anticipated result measurable?
6) Do you have the facts - all the facts?
7) Are they reliable?
8) What are the options?
9) Have other options been thoroughly considered?
10) What would happen if you did nothing?

The Engineering Approach

1) Define the problem
2) Use fundamentals to analyze and understand it
3) Determine and evaluate possible solutions
4) Implement the best
5) Repeat steps if possible gain seems worth the cost in time and effort

Four Aspects of Project Management

1) The work to be done
2) The resources available to do it
3) Timescale in which to complete the work
4) Finance available to fund it

Cost Effectiveness

Doing the best you can with the money you have

Productivity

Doing the best you can with the time you have

Al-Ahmady

2005-01-25T06:29:00.000-08:00

Hospital designed by Mohammad Wasim (with input from Geoff) for Mr. Al-Ahmady in Qatif (1996). As usual I had started with 1:100 plan-view sketches of the operating theatres and clean to dirty flow routes from CSD (adjacent to the theatres) out through to "dirty disposal". We also looked at dirty linen chutes down into the basement laundry but this was not taken up during construction.

2005-01-24T06:30:00.000-08:00

Another view of the Al-Ahmady Hospital. With the pre-cast panels in place, it almost looks finished. But in actual fact it was little more than a shell at this stage (1996). The water table was only a metre or so below the ground at the site ... and yet the client insisted on underground parking! A hostage to fortune? A never-ending commitment to pump maintenance at the very least!

Scrub Suits

2005-01-22T06:40:00.000-08:00

There may be a need to consider colour-coding of scrub suits (or "theatre clothing"). Operating theatre staff are not allowed to leave the OR suite in scrubs (and, of course, no-one is allowed to enter the suite without first changing into scrubs). However, other scrub-suit wearers (eg, A&E/ER staff) are often to be seen roaming around the hospital (and even outside). There is a danger that such a person could wander right into the OR without being challenged. There is a case, then, for OR staff proper and visitors to the OR suite to have a scrub suit of different colour to the others, so that interlopers may be readily identified and scrub discipline maintained.

Hospital Housekeeping

2005-01-21T08:33:00.000-08:00

The rule in housekeeping (Feldman's Rule) is to use the largest and most rugged machine that can do the job!

Mycology and Tuberculosis

2005-01-07T08:22:00.000-08:00

Mycology is the study of fungi.

There are 3 levels of mycobacteriology laboratory service:-

Level 1 : responsible for collecting and shipping specimens. If bio-safety requirements are met, Level 1 labs may also prepare smears and acid-fast stains (AFB - acid-fast bacilli) for microscopy.

Level 2 : performs Level 1 services and recover organisms by culture, identify isolates of m.tuberculosis and refer non-m.tuberculosis isolates of mycobacteria to Level 3.

Level 3 : performs all Levels 1 and 2 services, identify all species of mycobacterium and perform drug susceptibility tests.

Tuberculosis

Symptoms include persistent cough, fever, weight loss.

Confirmation is by tuberculin skin test, chest x-ray.

Definite diagnosis is made after isolation and identification of infecting organism in the lab:-

1) Decontamination, digestion, concentration of specimen
2) Microscope examination for acid-fast bacilli (AFB) on smears
3) Isolation by culture
4) Tests to identify recovered bacilli
5) Tests for drug susceptibility

M.tuberculosis notes:-

1) Culturing and identification is a long process. May take many days to report.
2) There are 25 species of mycobacterium, of which m.tuberculosis is one of the five most frequently encountered pathogenic species.
3) M.tuberculosis is transmitted by droplet. Therefore breaking or leaking during centrifuging is a hazard.
4) Bio-safety Laboratory Practice 3 (BSL-3) must be followed. Aerosol-generating procedures should be done in Class I or Class II biological safety cabinets, and centrifuging in aerosol-free cups.
5) Laboratory layout should provide separate areas for different activities.
6) BSL-2 space for preparing material and handling cultures and specimens.
7) BSL-3 space for manipulating cultures and specimens.
8) BSL-3 has safety cabinet and centrifuge, non-permeable walls and surfaces, low air pressure, air-lock, and HEPA filters direct to atmosphere.
9) Technicians should wear protective clothing and respirators. A changing room is therefore needed.

Equipment Specifications Formats

2005-01-04T05:30:00.000-08:00

1) Descriptive
2) Generic (...brief, able to be met by many manufacturers)
3) Manufacturer (..."shall be by Siemens" ... etc.)
4) Origin (..."shall be made in USA" etc.)
5) Performance (...shall be able to ....)
6) Reference (...to standards etc.)

...can be a composite of any or all of the above.

Specification writing

Twenty specs per writer per day is attainable (ten per day is better would result in better quality). So 100 per week can be achieved if pushed (ie, 20 specs/day x 5 days), but 50 per week is much better (that is, about one an hour).

Typical hospital may need 800 specs. So at least 8 weeks (2 months) are needed for complete the job of spec writing (but note that 4 months would be more comfortable)!

Specifications style options

1) Good specs should be generic and brief. They should not be geared to any particular manufacturer or supplier.

2) "...suitable for use..." eg:-
- in a hospital
- in an intensive care unit
- in an operating theatre
- by an executive manager ...etc.

3) Chair: Managers
...suitable for use by a manager.

4) MME-044 Monitor: NIBP: ECG: Portable

For monitoring of vital signs whilst patient is in transit. Powered from mains and internal battery. Compact, lightweight and able to be hung on patient trolley when necessary. Parameters to be monitored shall include:- ECG, heart rate, NIBP, SpO2 and temperature. Complete with bracket for mounting on IV pole, two sets of 3-lead ECG cables with clip-type leads, two sets of adult cuffs and tubing, one child cuff and tubing, two sets of adult SpO2 pick-up sensors, one child SpO2 sensor, one adult temperature sensor, one child temperature sensor, and start-up pack of disposable electrodes. (as written by for Al-Hasa Day Surgery 05-Mar-00).

1) What it is
2) Technical detail sufficient to "pin it down"
3) Relevant codes and standards

Laundries

2005-01-03T13:38:00.000-08:00

You can clean up on laundries! This apparently dull and mundane area is actually quite interesting once you get "stuck in".

Laundry Studies

- circulation within wards
- collection of dirty linen from ward to laundry

Circulation of linen within laundry
- arrival -> sorting
- sorting -> washing
- washing -> drying
- drying -> ironing and/or pressing
- ironing -> storage

Casework

2005-01-02T11:13:00.000-08:00

You can make a federal case out of casework! ... but the inspections are very tedious. Better to let other inspectors (eg, architectural) take care of them if you can!

Six basic types of casework:-

General casework
Laboratory casework
Pharmacy casework
Radiology casework
Reception stations
- department reception stations
- information stations
- nurses stations
- security stations
Special casework
- admissions
- appointments ... etc.

Early-on some basic decisions need to be taken, such as:-

Wooden or steel ?

Kitchens

2005-01-01T09:45:00.000-08:00

Spot the snag with this vegetable preparation table!

You can really make a meal of kitchens! At the 250 bed SANG hospital at Al-Hasa, review of the kitchen layout and equipment packages (190 items) from four prospective suppliers took one month to complete. And that did not include tableware and kitchen utensils (which were not included at Al-Hasa). Remember Don Laing at the Saudi MOH in the 1980's!

Kitchen studies can include:-

Flow of incoming food all the way to consumption

- Receipt
- Storage - refrigeration
- Preparation
- Holding
- Meal preparation - line conveyor
- Delivery to wards
- Serving at restaurant - serving line
- Collection and disposal
- Garbage system

The Medical Equipment Specialist

2004-12-03T08:28:00.000-08:00

During the 1970's and 80's there was a boom in hospital construction in the oil-rich countries of the Middle East. This was especially the case in Saudi Arabia, where modern healthcare services were to be brought to a population thinly scattered over a large area.

Local firms of architects and engineers were engaged as consultants to check the designs and supervise the work on behalf of clients, who were usually government agencies such as the Ministry of Health. In those early days, it was required that local Architectural and Engineering firms were to be in joint venture with international ones.

These local firms employed engineers and inspectors from the traditional trade disciplines (civil, electrical, mechanical etc.), and also a "Medical Equipment Specialist" to take care of the hospital equipment side of things.

The terms "Hospital Equipment Project Engineer" and "Equipment Inspector" are probably more accurate, but "Medical Equipment Specialist" prevailed. It is almost as much of a misnomer as "Biomedical Engineer"!

The following, taken from a job advertisement, gives a good idea of what it was all about:-

"Medical Equipment Specialist. A qualified engineer or equivalent who can supervise contractors and sub-contractors who will be installing all the medical equipment and services into a ... bed hospital in ... . Initially, the successful candidate will review the contractor's and sub-contractors' submittals including equipment specifications, redesigns and drawings. Later on the candidate will supervise installation and witness commissioning tests on behalf of the client at site".

Whatever he is called, such an engineer is part:-

Architect
Biomedical Engineer
Computer Programmer
Computer User
Designer
Electrical Engineer
Hospital Design Engineer
Inspector - all disciplines!
Mechanical Engineer
Medical Planner
Quantity Surveyor
Planning Engineer

A "Jack of all trades" perhaps, with "A little bit of knowledge ... "!!

Group 5 G-100 Hospitals

2004-12-02T11:31:00.000-08:00

The G-100 hospital up in the Asir mountains at Ballasmar during construction in 1984. Built by FEAL-IBS, as so many of them were. I went back there to do some equipment maintenance seven years later, and was pleased to find it still in good condition. Even the site offices were still there!

2004-12-01T13:16:00.000-08:00

Another one from Ballasmar (1984). Terry Hackler, Frank Acari, Phil Hackler and Geoff Hannis. Frank was still in his pajamas as it was a Friday morning (he didn't normally dress like that)!

2004-12-01T11:04:00.000-08:00

The G-100 hospital at Al-Namas, about 40 minutes drive from Ballasmar. I loved that place!
