Wife says her 79 yo mate won t take all his medicines. 3 October 10, 2016 MEDICARE CARE DELIVERY Man has an inborn craving for medicine. Heroic dosing for several generations has given his tissues a thirst for drugs. The desire to take medicine is one feature which distinguishes man, the animal, from his fellow creatures.

10 CDC assessment of opioid use Deaths from prescription drug overdose have quadrupled since Opioids can worsen pain and functioning. Risks increase with dose increases. Use of heroin and illicitly produced Fentanyl has increased. CDC recommends non-pharmacologic approaches.

20 Polypharmacy in preventive cardiology 1 Problem: Millions on CVD drugs* though proof of benefit lacking. Short-term study results are extrapolated over decades. Results from young-old subjects are extrapolated to old-old. We have scant evidence on outcomes of drug withdrawals. Modern clinical practice differs from that when trials were conducted.. Projections of benefits assume hazards are constant over time. Old-old adults may prefer different outcomes. * Aspirin, beta-blockers, statins, ACE inhibitors How long should these drugs be continued? 1 J Am Coll Cardiol 2015;66: October 10, Benefits of Deprescribing Simplify care Reduce ADEs Reduce hospitalization Improve adherence Reduce costs Save lives 40 October 10,
