AHA Scientific Statement
Drugs That May Cause or Exacerbate Heart Failure
A Scientific Statement From the American Heart Association
長長的列出一大串藥物,可以造成或是惡化心衰竭,排在最前面的就是NSAID (major)或是COX-2 inhibitors (major),另外還有糖尿病藥,Saxagliptin/Sitagliptin (major),還有metformin/TZD藥物等。還有患者PAOD常用的Cilostazol (major, evidence: A),或是心律不整藥(Diltiazem/Verapamil)。
藥物副作用機轉:Drugs may cause or exacerbate HF by causing direct myocardial toxicity; by negative inotropic, lusitropic, or chronotropic effects; by exacerbating hypertension; by delivering a high sodium load; or by drug-drug interactions that limit the beneficial effects of HF medications.
洗腎患者因多重疾病,常用了許多藥物(polypharmacy),因此這份藥物清單,可以給我們仔細看一下,患者到底用了幾種?有沒有機會可以停用?

目前2015, Medicare每年花$34 billion透析費用。
透析死亡率下降 36%,between 2001 and 2013。
The Corporatization of Dialysis Delivery
美國也是有愈來愈多,私人的透析院所,在shopping mall也有。
前二大透析器材供應商占了70%,Fresenius Medical Care and Colorado-based DaVita Healthcare Partners。
這二大供應商共有3,900透析點,幾乎是以下超市的數量總合(Target, Best Buy, and Publix Super Market stores)

根據USRDS,目前每位透析患者年花$88,000費用(透析+住院+急診),這數字超過一般美國家庭平均收入的60%。Fresenius的資料,美國透析患者,一季大約住院10天,(more than double the hospital days for its patients in Asia or Latin America)。(筆者註:台灣透析患者還是照顧得比美國好)
有non-profit 和 for-profit 經營者,non-profit的患者死亡率較低。
The big for-profit operators have also been shown to have much higher mortality rates than nonprofit dialysis centers in the U.S. A 2010 article inHealth Services Research tallied a 19% higher risk of death at Fresenius facilities, and a 24% higher death risk at DaVita facilities, than patients receiving care at the biggest nonprofit chain.
美國的透析患者死亡率比歐洲和日本高,原因可能是:營養不良,和工作人員的訓練不足。
2009, “Why Is the Mortality of Dialysis Patients in the United States Much Higher than the Rest of the World?” U.S. one-year mortality rates were among the highest in the world: 21.7% in 2003, versus 15.6% in Europe and 6.6% in Japan. The authors fingered patient nutrition and staff training as particular causes of the discrepancy.
Cost Growth, and Cutbacks
透析費用逐年成長,Medicare 2011年開始包裹給付,每次$240。
2011, Medicare began bundling dialysis care payments in an attempt to better control expenses, paying about $240 per treatment, or around $37,000 a year.
透析患者若是有私人保險,則一開始透析前30個月由私人保險給付,後來才由Medicare接手(私人保險給付透析的金額較高,約2倍)。
Private payers typically pay at least twice Medicare rates
Home dialysis可以節省透析費用支出,目前Fresenius’ and DaVita’s home dialysis rates hover around 20% and 10%, respectively.
Empowered Dialysis
1) 教病人透析時做瑜伽,增加循環。
Richard Gibney, MD, in Waco, Texas, Fresenius-owned dialysis centersYoga classes for patients as they’re being dialyzed — a response to the rising rates of diabetes among the patients and a need to increase their circulatory performance.
2) Gibney醫師,讓病人自己準備透析用品,設定,打針,以及自己監測透析、回應警報發生時處理,目前他有280位病人是"empowered dialysis",和傳統由護理人員操作透析相比,這群"empower dialysis"病人,有較少的死亡率和住院率。(瑞典首創‘hunker-down dialysis.’,據說可以減少33%透析費用和增加病人滿意度)
另一家醫療公司試圖用科技來幫忙透析:Outset Medical, based in San Jose, California
Tablo 會減少工資支出,減少medical complications (?),減少病人因故沒有至院所透析的機會,和透析技術人員的工作機會?(因為病人都可以自己操作機器了)
“I said ‘No, that’s totally wrong. We’re transitioning from you being a worker bee, a madman like you’re running cattle through a chute, to becoming teachers, mentors, and cheerleaders,’ ” he says.
筆者註:我怎麼覺得最後一段是在安慰透析從業人員的?當機器可以和病人配合把透析這件事做好,那還需要那麼多的員工嗎?時事評論一下:華航空姐這次罷工,成功得獲得所要求的權利固然可喜,然而華航高層目前會不會在想,「是不是該請鴻海郭董研發個機器人空姐了呢?」
