Wanna get out of the hospital alive?Well, the nursing staff has a lot to do with it.Now a study finds that a patient’s risk of dying _____1_____ the number of work shifts that a hospital is _____2_____ in nurses.The research was published in The New England Journal of Medicine.
The study included almost 198,000 patients, during nearly 177,000 eight-hour nursing shifts.
The research team originally reported that hospital nurse staffing ____3____ patients’ outcomes a decade ago.That study was challenged because data were collected at several institutions, and thus had ____4____ possibly confounding variables.In the current study, all data were collected at a single, large academic medical center in the U.S.
The researchers found that a patient’s risk of death increased by about two percent for each work shift that was what the researchers ____5____ as understaffed.Patients in the study averaged three such shifts, which meant that their risk of dying increased by more than six percent compared with patients with access to fully staffed nursing teams.So when it comes to nurses it’s about quality—and quantity.

護士數(shù)量少=死亡風險高？！
想活著走出醫(yī)院嗎？當然，這也不是不可能，只是這與醫(yī)院看護人員有著莫大的關系。如今一研究發(fā)現(xiàn)，病人死亡的風險隨醫(yī)院缺少醫(yī)護人員導致的輪班次數(shù)改變而增加。此研究發(fā)表在《新英格蘭醫(yī)學雜志》上。
該研究在將近十七萬七千個八小時輪班護理的過程中，調查了大約十九萬八千名患者。
研究團隊曾在十年前就已經發(fā)現(xiàn)患者的存亡率與醫(yī)院的護理人員有著密切關系。由于此前的數(shù)據(jù)是從數(shù)所醫(yī)院獲取的，其中難免會存在一些影響結果的混雜變量，所以該調查結果受到了質疑。近期調查中，所有數(shù)據(jù)都取自美國的一所獨立的大型醫(yī)療學術中心。
研究人員發(fā)現(xiàn)，對于那些醫(yī)護人員不足的醫(yī)院來說，每輪班一次，患者死亡的風險就會增加百分之二。調查中的患者平均由三班醫(yī)護人員護理，與那些由全職醫(yī)護人員護理的患者相比，他們的死亡風險上升了不止百分之六。因此，醫(yī)護人員保證護理質量的同時也要保證數(shù)量。
