Quantitative measurement vs descriptive impressions

Quantitative measurement vs descriptive impressions

“It’s cold outside” – 35ºF or 10ºF?“My child has a fever” – 100ºF or 108ºF?“This wine is expensive”– $60 or $6000?

“The RA patient is better” – –DAS28 ↓ 4.2 or 2.4?–CDAI ↓ 16 or 5? –RAPID3 ↓ 10 or 4?

“Patients with rheumatoid arthritis usually respond to a conservative program of nonsteroidal anti-inflammatory drugs, rest, and physical therapy…”

Traditional approaches to clinical expertise:

EMINENCE BASED MEDICINE - making the same mistakes with increasing confidence over an impressive number of years

ELOQUENCE BASED MEDICINE - a year-round suntan and brilliant oratory may overcome absence of any supporting data

ELEGANCE BASED MEDICINE - where the sartorial splendor of a silk-suited sycophant substitutes for substance

The modern alternative?

EVIDENCE BASED MEDICINE - the best approach to clinical data - requires information from clinical observational data in addition to clinical trialsIsaacs and Fitzgerald, BMJ 319:1618, 1999,per G. Eknoyan, Baylor Coll Med

Complexities in diagnosis and assessment of patients with rheumatic diseases

No single ‘gold standard’ (e.g., blood pressure, cholesterol) for clinical trials or standard care

Laboratory tests limited in both diagnosis and treatment; primary criteria are clinical

Patient history and physical examination generally are more important in clinical decisions than lab tests

Therefore, indices of 3-7 measures to assess RA quantitatively – include history (pt questionnaire), physical exam, lab tests

Standardized measurement required for the scientific method in medicine

• A patient with hypertension, diabetes, osteoporosis, etc. goes to the doctor to find out how she/he is doing, based on “gold-standard” measures by the doctor.

• A patient with RA goes to the doctor to tell the doctor how she/he is doing.

• Why not record the patient history as standard, “scientific” data?

Some Limitations of Laboratory Tests in RA

Some Limitations of Laboratory Tests in RA

1. Normal in 30-50% of patients who require treatment for RA

2. Often not available at time of clinical decision

3. Add to costs needed for therapy

Page 34: Why is quantitative standardized measurement advantageous in usual clinical care?

Why isn’t a joint count the best

quantitative measure in RA?

Page 35: Why is quantitative standardized measurement advantageous in usual clinical care?

Joint counts in RA Joint exam needed for diagnosis Joint count is the most specific measure of RA

status. The most specific measure may not be the most

informative measure. Poorly reproducible by different observers - must

be done by same observer – not GP, infusion, etc. Most likely to improve with placebo Rigorous formal joint count not performed at

most visits

measure to assess rheumatoid arthritis.

Some approaches to overcome limitations of joint counts in RASome approaches to overcome limitations of joint counts in RA

1. All visits must include a careful joint examination, but not formal joint count

2. A RADAI self-report joint count may perform well to characterize joint involvement

3. Can a patient global score for inflammation, as well as damage, and neither (fibromyalgia/somatization), provide clinically useful quantitative data from a health professional?

Four physician global estimates: 1.Overall, 2. Inflammation,

3. Damage, 4. Neither

The expertise of a rheumatologist is to determine whether a patient’s pain, fatigue, distress, etc. results from inflammation, damage or neither. Why not record scores?

MTX and radiographic progression“When used as monotherapy, the structure-

sparing effects of MTX is quite modest compared with that of TNF blockers, even if MTX is used in DMARD-naïve patients.”

Schett et al. Arthritis Rheum 2008

“…studies of anti-TNF therapy plus MTX, compared with the effect with MTX alone, have shown that although MTX is relatively effective at relieving clinical symptoms, it has little or no effect on underlying radiological progression.”

Page 66: Why is quantitative standardized measurement advantageous in usual clinical care?

Let the patient do most of the work! Most patients are more accurate about many details of their own medical history than health professionals

Page 67: Why is quantitative standardized measurement advantageous in usual clinical care?

MDHAQ helps the patient prepare for a better visit

Page 68: Why is quantitative standardized measurement advantageous in usual clinical care?

MDHAQ/RAPID3Advantages to patient

• Prepares patient for encounter

• Simple format for patient to communicate level of pain, fatigue, function, exercise, symptoms

• Quantitative data for any doctor – not restricted to specific rheumatologist

• “Benchmark” to compare to future visits

• Assures inclusion of important patient symptoms and recent medical history

Page 69: Why is quantitative standardized measurement advantageous in usual clinical care?

Doctor reviews information with the patient,and interprets data for clinical decisions

Page 70: Why is quantitative standardized measurement advantageous in usual clinical care?

MDHAQ/RAPID3Advantages to doctor

• Saves time – especially recent history, symptom review, self-report joint count

• Doctor is not measurer but interprets measures

• Specific doctor not required, unlike joint count

• Familiar, standard format for patient data

• Quantitative data for “treat to target” strategy

• Clues to possible fibromyalgia/distress

• MDHAQ – all key data on one page

• “Benchmark” to document future status

• “Checklist” documentation of patient status

Goodman and Gilman Textbook of Pharmacology, 2006 edition:

"Although aspirin is regarded as the standard against which other drugs should be compared for the treatment of rheumatoid arthritis, many clinicians favor the use of other NSAIDs perceived to have better gastrointestinal tolerability, even though this perception remains unproven by convincing clinical trials.

Patients with progressive or resistant disease require therapy with more toxic, second-line drugs, such as antimalarials, glucocorticoids, methotrexate, or immunosuppressive agents.

MDHAQ/RAPID3 in Clinical Rheumatology• MDHAQ – not joint count, X-ray, or lab test – best predictor

of work disability, death in RA• RAPID3 distinguishes active treatment from placebo as

efficiently as DAS28, CDAI• Useful in all rheumatic diseases –

NSAID from acetaminophen in OA vs WOMAC fibromyalgia from RA vs ESR

• Identify incomplete response to Mtx, biologic• Completed before visit - prepares patient• RAPID3, recent history and review of systems save time for

doctor – improve documentation• Flow sheets are very helpful• Does not replace history and physical exam• Does not prevent joint count imaging, etc.
