Practice Variation in the Use of Cardiac Procedures- SummaryThe ACC is leading the way for specialty society

efforts to reduce inappropriate proceduresGeneral internists should be active

collaborators rather than passive observers in engaging with specialty colleagues in reducing practice variationMedical staff involvementCollegial physician-physician communication

Increased transparency of local and regional utilization patterns is coming and can potentially reduce ineffective or marginally effective utilization

JAMA 2009 302;1658-1665

Aldosterone Antagonists in CHFPatients admitted for CHF may have

multiple medication changesClinician concern about initiating multiple

interventions may be a barrier to initiating treatment

Dose intensification of multiple medications is generally needed in CHF patients

Clinical inertia may be a barrier to optimal care in CHF

Determinants and Outcome of Watchful Waiting in Men with Prostate CancerHealth Professionals Follow-up Study

Cohort 51,529 men3331 diagnosed with prostate cancer 1986-2007342 chose watchful waiting

51% remained untreated after 7.7 yearsTreatment delayed average of 3.9 years in

those undergoing treatmentNo difference in prostate cancer death or

metastatic disease (about 10 per 1000 pt-years)

Age, tumor size, Gleason score, PSA level predicted future treatment

PSA ≤ 10, Gleason <7 Stage 1 and 2

PSA 10.1-20 or Gleason 7, Stage 1 or 2

PSA > 20 or Gleason >7, or Stage 3

Radical Prostatectomy vs. Watchful Waiting in Early Prostate Cancer695 men age < 75, life expectancy > 10 years,

T1 or T2 tumor randomized to RP or WWOnly 12% non-palpable T1c tumors at enrollment5% diagnosed by screening≈ 75% T2 tumors> 45% with PSA >10

RP patients received hormonal therapy for recurrence

WW patients underwent TURP for obstructive symptoms

Median follow-up 12.8 years

NEJM 2011 364:1708-117

NCCN GuidelinesActive surveillance reasonable option for

men withStage T1-2a, Gleason score ≤ 6, PSA < 10

Active surveillancePSA at least every 6 monthsDRE at least every 12 monthsBiopsy 6 months if initial bx. < 10 coresBiopsy 18 months if initial bx. ≥ 10 cores

Prostate Cancer Screening-ConclusionsPSA screening may provide small survival benefit

Pre-screening, contamination, biopsy threshold and treatment differences limits data interpretation

Survival curves start to diverge at about 10 yearsSignificant benefit may take longer

Overdiagnosis is a serious health hazardOver 1 million treatedSide effects immediateImpact of overdiagnosis could be dramatically

reduced if active surveillance was initial treatment strategy in appropriate patients

Shared decision making should emphasize delayed benefit, short term risk, baseline health and option for delayed curative treatment

Collaboration with urology community to determine treatment options is essential
