Hospitals..

[*!*arch*!*]

Can someone plz help me with this CR?.. I found this a bit confusing!.. Thanks a lot.
Lists of hospitals have been compiled showing which hospitals have patient death rates exceeding the national average. The data have been adjusted to allow for differences in the ages of patients.
Each of the following, if true, provides a good logical ground for hospitals to object to interpreting rank on these lists as one of the indices of the quality of hospital care EXCEPT:

(A) Rank order might indicate insignificant differences, rather than large differences, in numbers of patient deaths.

(B) Hospitals that keep patients longer are likely to have higher death rates than those that discharge patients earlier but do not record deaths of patients at home after discharge.

(C) Patients who are very old on admission to a hospital are less likely than younger patients to survive the same types of illnesses or surgical procedures.

(D) Some hospitals serve a larger proportion of low-income patients, who tend to be more seriously ill when admitted to a hospital.

(E) For-profit hospitals sometimes do not provide intensive-care units and other expensive services for very sick patients but refer or transfer such patients to other hospitals.

IMO - E

As that sounds immoral (For-profit hospitals sometimes) and there cannot be proper records to justify these kind of incidents.

Used POE and arrived at E.But not able to envision the meaning correctly

[*!*arch*!*]

The OA is (C).. Can someone plz help reason out the answer?

For me C.

(A) Rank order might indicate insignificant differences, rather than large differences, in numbers of patient deaths. Rank order can be criticised for not giving significant weight to the differences between the objects.

(B) Hospitals that keep patients longer are likely to have higher death rates than those that discharge patients earlier but do not record deaths of patients at home after discharge. We can also use this fact to raise question on the sanctity of the ranking.

(C) Patients who are very old on admission to a hospital are less likely than younger patients to survive the same types of illnesses or surgical procedures. The data have been adjusted to allow for differences in the ages of patients. Since the data have been adjusted to allow for differences in the ages of patients this logic can't be extended to counter the rank order list.


(D) Some hospitals serve a larger proportion of low-income patients, who tend to be more seriously ill when admitted to a hospital. We can use this statement also for the higher rates in some hospitals where the patients are of low-income group.

(E) For-profit hospitals sometimes do not provide intensive-care units and other expensive services for very sick patients but refer or transfer such patients to other hospitals. If for-profit hospitals transfer critical patients to some other hospitals and if the patients die there then for-profit hospitals patients death rate will be less that what it would have been without the transfer. And this process will increase the no. of rate of deaths in other hospitals where the patients were transferred.

excellent explanation.. thanks a lot
