Question of the week # 480

A 32-year-old man comes in regularly because his back hurts. You suspect malingering because he continually requests narcotic pain relievers and imaging studies of his spine. He has come 5 times in the last 6 months with the same problem, typically stating that the pain improves with exercise and leaning forward but is worse at night; pain also occurs at times in his buttocks and does not improve with rest. On physical examination you find no abnormalities of the spine besides inflexibility of the lower spine when he leans forward. Neurological examination is normal, including the absence of pain on a straight-leg raise test. X-ray of the spine and sacroiliac joint is normal. All blood tests including rheumatoid factor, ESR, and C-reactive protein are normal. Today, he again claims to have only minimal improvement with ibuprofen. He is requesting narcotics and a “doctor’s note to get out of work.” What is the next best step in management?

A. MRI of the sacroiliac joint
B. Anti-cyclic citrullinated peptide (anti-CCP)
C. HLA-B27 testing
D. Methotrexate
E. Report to employer for malingering

USMLE Step 3 – New Format Results released 03/25 – CCS remains critical to pass.

Congratulations to everyone who passed! Results were held over the past 5 months and were just released. We just received over-whelming number of e-mails from our students reporting their scores and pass/ fail status. About 95% of our students have passed and that is very encouraging. This should allay the fears about new Step 3. New format Step 3 has increased representation of bio-statistics, epidemiology, ethics and preventive medicine/ screening guidelines. Number of students were actually quite worried about increased proportion of Bio-statistics questions but it appears like most of them have done really well on that part of the exam. Looking at some of the score reports even those who failed the exam have surprisingly done well on bio-statistics and other multiple choice questions. Failures predominantly happened again because of not placing enough emphasis on CCS preparation and scoring too low on the CCS. Improving on CCS and moving your performance graphs towards the right ( good to excellent performance) may help you pass much easily even when you do just average or slightly below-average on the MCQs. Scoring higher on CCS reduces your burden by easing off the requirement to answer more number of MCQs.

Check our prior analysis on step 3 score reports http://www.ccsworkshop.com/About_us.html . This has not changed much on new Step 3. Please check the back portion of the score report of one of the students who failed with 184. Note how this student has failed despite doing fairly well on MCQs including the dreaded Bio-statistics ( Image below)  It goes on to prove CCS can not be neglected and you must score at least above average to do very well on step 3.

Question of the Week # 461

Q461) A clinical trial is evaluating an investigational new drug (Drug A) as compared with standard therapy (Drug B) in patients presenting to the emergency department with myocardial infarction (MI). The study enrolled a total of 3,000 subjects, 1,500 in each study arm. Follow-up was conducted at 45 days post-MI. The following are the results of the trial:

Endpoints Drug A Drug B P-Value
Primary:

·         Death from cardiovascular causes

134 210 0.03
Secondary:

·         Hyperkalemia

57 70 0.4

What is the relative risk of death from cardiovascular cause? (Round to the nearest whole number)

A. 36%
B. 42%
C. 57%
D. 64%
E. 72%

Taking the restructured USMLE STEP 3 ? Starting NOVEMBER 2014, Step 3 undergoes some changes!

Archer USMLE Theory Courses have placed huge emphasis on Preventive Medicine, Ethics, Patho-physiology which are going to be tested even more frequently on restructured USMLE Step 3.

Please note USMLE Step 3 CCS will be administered on Day 2 and content , software and format of CCS will remain the same as before!! You may access CCS Workshop at CCS Workshop 

Changes to USMLE 2014 – 2015
As medicine and medical education have changed over the years, so have USMLE examinations evolved since they were first administered in 1992. This is a brief summary of planned changes for the next few years.

USMLE STEP 3

What WILL change?

Beginning November 3, 2014, examinees will:

 Be able to take the exam on two consecutive or non-consecutive days;

 NOT need to apply for Step 3 under the eligibility requirements of a specific medical licensing authority;

 See increased numbers of items that assess an expanded range of competency-based content, including foundational science essential for effective healthcare; biostatistics, epidemiology, and population health; literature interpretation; medical ethics; and patient safety. The two exam days will be named Step 3 Foundations of Independent Practice (FIP) and Step 3 Advanced Clinical Medicine (ACM).

What WILL NOT change?

The Step 3 exam will continue to:

 Focus on knowledge and application of the biomedical and clinical sciences necessary for independent patient care;

 Include multiple-choice questions and computer-based case simulations;

 Be administered over two days, for a total time comparable to current testing time;

 Result in a single score (with graphical performance profile information) and a single pass/fail outcome after completion of both examination days.

 Be administered at Prometric test centers throughout the United States.

Important to Note : ( Taken from USMLE Official website) :

 Applications for the restructured Step 3 examination will be accepted starting on August 4, 2014.

 No Step 3 examinations will be administered during most or all of October 2014.

 Administration of the restructured Step 3 exam will begin on November 3, 2014.

 There will be a score delay following introduction of the restructured Step 3 examination on November 3, 2014. The duration of the score delay will be determined by examinee volume during the early months of exam administration. Based on historic trends, we estimate that scores for Step 3 exams taken on or after November 3, 2014 will be released in April 2015.

GOOD LUCK WITH YOUR EXAM!
