Bisphosphonates and ONJ

Bisphosphonates and ONJ

Clinical Question
Are patients on bisphosphonate therapy at risk for developing osteonecrosis of the jaw (ONJ)?

Bottom Line
Osteonecrosis of the jaw has been described in patients on bisphosphonate therapy. All reports have been either case reports or small case series. The nature of the association has not been definitively established.

Colorectal Cancer (CRC) Screening

CRC Screening

Clinical Question
When screening average-risk patients over 50 years of age for colorectal cancer (CRC), is colonoscopy alone, or yearly fecal occult blood test (FOBT) plus either sigmoidoscopy or barium enema (BE) better than yearly FOBT alone?

Bottom Line

Screening for CRC in average-risk individuals aged 50 and older has received an “A” recommendation from the USPSTF. However, current evidence is insufficient to determine which screening modality or combination is superior. Strategies include: (1) annual FOBT alone; (2) annual FOBT and either sigmoidoscopy or barium enema (BE) every 5 years; or (3) colonoscopy alone every 10 years.

Coronary Artery Calcium (CAC) Score

CAC Score

Clinical Question
Does the use of the coronary artery calcium score (CACS) to screen asymptomatic individuals for coronary heart disease (CHD) lead to more clinical benefit than harm?

Bottom Line
There have been no large-scale prospective trials demonstrating more benefit than harm when the CACS is used to systematically screen asymptomatic individuals.

Top of page


Carotid Intima

Carotid Intima

Clinical Question
In patients at risk for coronary atherosclerosis, does the use of carotid intima media thickness (IMT) measurement lead to better outcomes?

Bottom Line
The clinical utility of Carotid Intima Media Thickness (IMT) measurement will remain unclear until prospective clinical trials are performed using patient oriented outcomes.

Top of page


Chest CT and Lung Cancer

Chest CT and Lung Cancer PDF

Clinical Question
In patients at increased risk for lung cancer, does screening with routine chest CT result in improved survival or quality of life compared to patients who are diagnosed on the basis of symptoms?

Bottom Line

Although spiral CT can detect early lung cancer, the evidence remains insufficient to demonstrate that chest CT screening for patients at increased risk for lung cancer decreases mortality or improves quality of life.

Top of page


COX-2

COX-2
Patient Education: NSAIDs and COX-2 Inhibitors

Clinical Question

In patients requiring anti-inflammatory therapy, should COX-2 inhibitors be used?

Bottom Line

The current, available evidence does not clearly demonstrate a safe dose or duration of dosing for coxibs free of excess cardiotoxicity.

Top of page


Diabetes Mellitus (DM) Diet

DM Diet

Clinical Question
In patients with Type 2 DM, do low fat diets compared to low carbohydrate diets lead to better patient-oriented outcomes?

Bottom Line

There are no high quality data on the efficacy of any particular diet in the treatment of Type 2 DM. Reduced energy diets appear to be more important than any particular combination of fat or carbohydrate intake. When combined with exercise, reduced energy diets lead to better glycemic control.

Top of page


DVT - Once Daily Low Molecular Weight Heparin

Once Daily LMWH

Clinical Question
In patients with deep venous thrombosis (DVT), does once daily (1.5 mg/kg) low molecular weight heparin (LMWH) dosing result in similar efficacy and adverse events as twice daily (1.0 mg/kg) therapy?

Bottom Line

Once daily LMWH is as effective as twice daily therapy in preventing recurrent thromboembolism and does not result in higher mortality or major bleeding.

Top of page


Early Prostate Cancer

Early Prostate Cancer

Clinical Question
Is radical prostatectomy (RP) compared to watchful waiting (WW) a more effective treatment for early prostate cancer?

Bottom Line

Compared to WW, RP appears to confer a mortality benefit in healthy men under 75 with symptomatic, localized, well- to moderately well-differentiated prostate cancer.

Top of page


Epidural Steroid Injections

Epidural Steroid Injections

Clinical Question
In patients with chronic low back pain (LBP), do epidural steroid injections (ESI’s), single or multiple, provide better pain control and reduce the need for subsequent surgery compared to traditional conservative therapy?

Bottom Line

ESI’s provide limited short term symptom relief but do not provide long term (>6 weeks) improvement in patients with sciatica or neurogenic claudication due to spinal stenosis. There are no Level 1 or 2 studies that support a multiple injection strategy for long-term symptom relief or a reduction in the rate of subsequent back surgery.

Top of page


Floppy Iris Syndrome

Floppy Iris Syndrome

Clinical Question
Is there a causal association between alpha-1 adrenergic antagonist exposure and the intraoperative floppy iris syndrome (IFIS)?

Bottom Line

While a causal relationship has not been established, an awareness of this association will allow changes in operative technique that may reduce the rate of operative complications.

Top of page


Glomerular Filtration Rate (GFR) Calculation

GFR Calculation

Clinical Question
Which derived formula for glomerular filtration rate (GFR) most closely approximates the physiologic value?

Bottom Line

The Modification of Diet in Renal Disease (MDRD) and the Cockroft-Gault (C-G) equations provide useful estimates of GFR in adults.

Top of page


Headache and Imaging

Headache and Imaging

The vast majority of patients seen in clinical practice with headache have primary headaches: migraine, tension type, and cluster. For patients with a stable headache pattern, normal neurologic exam, and the absence of red flags for secondary headaches, brain imaging has a 0.4% yield of positive findings.

Top of page


Hydroquinone

Hydroquinone

Clinical Question
Do patients treated with topical formulations containing Hydroquinone (HQ) experience increased rates of exogenous ochronosis, leukemia or lymphoma?

Bottom Line

Although animal models have raised the possibility of carcinogenic potential, no human studies have demonstrated more serious toxicity.

Top of page


iFOB Test

iFOB Test

Clinical Question
In patients undergoing CRC screening, is immune fecal occult blood (iFOB) testing with HemeSelect®, compared to current Dean Clinic FOBT (Hemoccult II Sensa®) associated with better patient-oriented outcomes?

Bottom Line

iFOB has greater specificity but less sensitivity than Hemoccult II Sensa®. To our knowledge, there are no prospective studies addressing whether this approach leads to decreased CRC or overall mortality.

Top of page


Intensive Statin Rx

Intensive Statin Rx

Clinical Question
In patients with coronary heart disease (CHD), does high dose statin therapy provide greater clinical benefit compared to regular dose statin therapy?

Bottom Line

The cited meta-analysis does not demonstrate a mortality benefit with the use of intensive statin therapy compared to regular statin therapy for CHD patients, but it does show a consistent clinical benefit in terms of reduced cardiovascular events.

Lab Testing During Complete Physicals

Lab Testing During Complete Physicals

The purpose of this Pearl is to stimulate discussion among physicians about the value of laboratory testing.

Top of page


Why Lotrisone Is Seldom the Best Choice

Why Lotrison Is Seldom the Best Choice

Lotrisone (and generic equivalents) are among the most widely prescribed topical medications in the United States. There are several reasons why Lotrisone is seldom the treatment of choice.

Bottom Line
Avoid Lotrisone to reduce costs, side effects and treatment confusion. Make your best diagnosis and then treat accordingly.

Top of page 


Methotrexate

Methotrexate

Clinical Question
Should patients on methotrexate (MTX) therapy be monitored at a specific and consistent interval?

Bottom Line

It is unclear whether liver test monitoring in the setting of MTX therapy should be standardized across different departments that are using it for different disease entities.

Top of page


MRI and Hardware Safety

MRI and Hardware Safety

Clinical Question
Do patients with cardiac rhythm management devices have an absolute contraindication to MRI scanning?

Bottom Line

Given the potential for significant adverse events such as lead heating, arrhythmogenesis, and device movement, further study is required before endorsing use of MRI in patients with pacemakers or ICDs.

Top of page


MRI Imaging and Low Back Pain

MRI Imaging and Low Back Pain

MRI imaging of the lumbar spine is costly and frequently over utilized during the evaluation of acute low back pain of a less than six week duration.

Top of page


Mumps Algorithm

Mumps Algorithm

Clinical Question
What is the Dean Health System consensus on the approach to the patient with suspected mumps?

Bottom Line

See algorithm.

Top of page


NMR Lipoprofile

NMR Lipoprofile

Clinical Question
Should NMR lipoprofile be clinically used to assess cardiovascular risk?

Bottom Line

At this time, there is insufficient evidence to show that NMR lipoprofile should be used for routine cardiovascular risk screening.

Top of page


NSAID GI Toxicity

NSAID GI Toxicity

Clinical Question
Do patients taking prolonged non-steroidal anti-inflammatory drugs (NSAIDs) and gastro-protective medications experience fewer adverse gastrointestinal (GI) complications as compared to patients taking NSAIDs who do not take gastro-protective medications?

Bottom Line

Gastro-protective medications reduce the risk of NSAID induced peptic ulcer disease in high risk patients. If NSAIDs are used in high risk patients, the lowest effective NSAID dose should be used with a mucosoprotective agent such as omeprazole 20 mg qd. 

Top of page


Perioperative Statin Use

Perioperative Statin Use

Clinical Question
Should patients discontinue statins prior to general anesthesia in order to prevent rhabdomyolysis or other complications?

Bottom Line

Pre-operative exam physicians should advise patients taking statins and contemplating major surgery to continue statins unless there are other risk factors that could contribute to rhabdomyolysis.

Top of page


Pertussis

Pertussis Algorithm

Clinical Question
What is the DHS consensus on the approach to the patient with suspected pertussis?

Bottom Line

See algorithm.

Top of page


PETs for OME

PETs for OME

Clinical Question
In pediatric patients with otitis media with effusion (OME), does insertion of tympanastomy tubes compared to conservative (non-operative) management result in improved hearing and developmental outcomes?

Bottom Line

Although short term gains in hearing have been noted, tympanostomy tube insertion compared to conservative management has not been shown to result in long term improvements in speech and language development.

Top of page


Post CABG/PCI Cardiac Testing

Post CABG/PCI Cardiac Testing

Clinical Question
In patients who have undergone percutaneous coronary intervention (PCI) or coronary artery bypass surgery (CABG) and who remain asymptomatic, does regular periodic exercise testing result in improved patient outcomes?

Bottom Line

There is no evidence that a strategy of regular periodic exercise testing improves patient-oriented outcomes.

Top of page


PPI Use and Hip Fracture

PPI Use and Hip Fracture

Clinical Question
Are patients on long term acid suppression therapy, compared to patients not receiving such therapy, at increased risk of developing hip fractures?

Bottom Line

A causal association between long term acid suppression therapy and hip fracture has not been established.

Top of page


Preoperative Laboratory Testing

Preoperative Laboratory Testing

In 2005, Dean charged over $2.1 million on preoperative laboratory testing.
Preoperative laboratory testing in healthy asymptomatic adults does not decrease the risk of surgery or result in any improvement in patient outcomes.

Top of page


PT and Low Back Pain

PT and LBP

Clinical Question
Do patients with low back pain who undergo physical therapy have better outcomes than those who are encouraged to pursue a self-paced fitness program or given an advice booklet in the office?

Bottom Line

Physical therapy provides no advantage in functional recovery.

Top of page


Renal Artery Stenosis (RAS) and Stenting

RAS and Stenting
AHRQ RAS Clinician Guide

Clinical Question
In patients with hypertension and atherosclerotic renal artery stenosis (RAS), does percutaneous transluminal renal artery angioplasty plus stenting (PTRA-S) improve renal function, blood pressure control or mortality compared to aggressive medical therapy alone?

Bottom Line

It remains unclear whether percutaneous transluminal renal artery angioplasty plus stenting (PTRA-S) provides more clinical benefit than aggressive medical therapy alone. The identification of patients with RAS who are considered appropriate candidates for PTRA-S is currently based on expert opinion.

RST - A Negative Rapid Strep Test (RST) in Adults Does Not Require A Routine Confirmatory Throat Culture

RST - A Negative Rapid Strep Test (RST) in Adults Does Not Require A Routine Confirmatory Throat Culture

The use of a rapid strep test (RST) alone (or a throat culture alone) is sufficient for the management of patients > 18 years of age suspected of having strep pharyngitis.

Bottom Line
Eliminate a confirmatory throat culture in patients > 18 years of age by ordering a RST alone.

Spirometry (Asthma) CPA

Spirometry (Asthma) CPA

Clinical Question
In the routine primary care management of asthma patients, does the addition of point-of-care spirometry in the primary care office, compared to referral spirometry, result in better patient-oriented outcomes?

Bottom Line

Patient-oriented effectiveness studies comparing point-of-care spirometry in the primary care office to referral spirometry have not been performed.

Top of page


SSRI Treatment for Major Depression

SSRI Treatment for Major Depression

Clinical trials of the five most frequently prescribed SSRIs (citalopram, escitalopram, fluoxetine, paroxetine, and sertraline) do not show differences in efficacy. Rates of response, remission, and discontinuation do not differ substantially among the drugs.

Top of page


Tamoxifen

Tamoxifen

Clinical Question
In women taking tamoxifen, does the use of SSRIs (and other agents) that strongly inhibit CYP2D6, compared to the use of weaker inhibitors of CYP2D6, result in worse patient oriented outcomes such as mortality, time-to-recurrence, or relapse free survival?

Bottom Line

Although the evidence is not conclusive, it seems prudent to avoid prescribing strong CYP2D6 inhibitors such as fluoxetine, paroxetine, bupropion, and quinidine in tamoxifen-treated women.

Top of page


Thyroid Screen for Diabetes Mellitus (DM) and Depression

Thyroid Screen for DM and Depression

Clinical Question
In depressed diabetics, does systematic screening for thyroid disease produce superior outcomes compared to symptom-based case finding or to no screening?

Bottom Line

Evidence is insufficient to recommend systematic screening for thyroid disease in any chronic disease subgroup, including depressed diabetics.

Top of page


Virtual Colonoscopy

Virtual Colonoscopy

Virtual Colonoscopy - Patient Education

Clinical Question
In a general patient population undergoing colorectal cancer (CRC) screening is virtual colonoscopy superior to standard colonoscopy in detection of polyps, patient comfort, or cost?

Bottom Line

It is too early to recommend virtual colonoscopy for the general patient population.

Top of page


Very Low Calorie Diet and Weight Loss

VLCD and Weight Loss

Clinical Question
In obese patients (BMI >30), does one particular very low calorie diet (VLCD) achieve superior results with regard to weight loss maintenance?

Bottom Line

Taken together, the evidence is insufficient to recommend one specific VLCD over another.

Top of page


VTE Prophylaxis After Knee or Hip Surgery

VTE Prophylaxis After Knee or Hip Surgery

Clinical Question
Are any of the currently available anti-thrombotic strategies superior in the prevention of thromboembolic complications of major lower extremity orthopedic surgery?
