Between 1975 and 1985, nursing-home occupancy rates averaged 87% of capacity, while admission rates remained constant, at an average of 95 admissions per 1,000 beds per year. Between 1985 and 1988, however, occupancy rates rose to an average of 92% of capacity, while admission rates declined to 81 per 1,000 beds per year.

If the statements above are true, which of the following conclusions can be most properly drawn?

A: The average length of time nursing-home residents stayed in nursing homes increased between 1985 and 1988.
B: The proportion of older people living in nursing homes was greater in 1988 than in 1975.
C: Nursing home admission rates tend to decline whenever occupancy rates rise.
D: Nursing homes built prior to 1985 generally had fewer beds than did nursing homes built between 1985 and 1988.
E: The more beds a nursing has, the higher its occupancy rate is likely to be.

A and C both are close.

I would choose option A.

If the average length of time nursing-home residents stayed in nursing homes increased between 1985 and 1988, it is likely that the beds were occupied for a longer duration. This explains the rise in occupancy rate to 92%of the years(1985-88) the hospital beds were occupied OR 92% of the hospital beds were occupied for every year between 1985-88.
The decline in admission rate may or may not be attributed to the increase in occupancy rate, due to the below reasons:-

1. It could be that because more beds were occupied and therefore less admissions were possible
2. It could be that the no. of people who were ill and required to be admitted in the nursing homes increased between 1985-88 and the no. of beds remained the same, hence less admissions were possible.
3. It could be that the no. of beds were reduced that resulted in less admissions.

None of this is clearly stated in the paragraph. But we definately know that an increase in the average length of time nursing-home residents stayed in nursing homes would directly increase the no. of beds occupied and hence occupancy rate. Therefore A seems to be the best conclusion.

agree with A)

C) should be out because there is no proven correlation stated in the argument between the admission and occupancy rates

E: The more beds a nursing has, the higher its occupancy rate is likely to be.


This type of questions needs the conclusion that is supported by all the evidences given

i) Between the period 1975 and 85

nursing-home occupancy rates averaged 87% of capacity, while admission rates remained constant, at an average of 95 admissions per 1,000 beds per year

ii) Between 1985 and 1988, however, occupancy rates rose to an average of 92% of capacity, while admission rates declined to 81 per 1,000 beds per year.


This means that the people in the nursing homes had longer stay (occupancy increased) and hence the decrease in admission rate.

Choice A aptly says AVERAGE period of occupancy increased between ...

Hence the answer

SOS!!!!

please help me to understand the two terms mentioned in the stem

1) occupancy rate
2) admission rate

occupancy rate- what i understand, a occupancy rate of 87% per year means that 87 beds were occupied through out the whole year.

admission rate- a admission rate of 95 per year, means that a single bed was occupied by 95 diff patients in a year

do you think i am correct,
what i dont understand is, what is meant by admission rate of 95 PER 1000 BED per year. why is 1000 BED included? what is its significance??

Hi dispaksingh,
I initially had a same question as you did here. My comments are inserted below.

occupancy rate- what i understand, a occupancy rate of 87% per year means that 87 beds were occupied through out the whole year.

---> I think you are right.

admission rate- a admission rate of 95 per year, means that a single bed was occupied by 95 diff patients in a year

---> I saw 95 admissions per 1,000 beds per year is just a reference for you to know whether you have the higher admission rate between 85 & 88 and 75 and 85 compared to occupancy rate between the same timeframe.

We don't know the total number of beds in 85 or 88, but assuming the total beds are 1,000(as an example), 870 beds(87%) were occupied in 85 and 920(92%) in 88. 870 can be split into 775 and 95(new admission) and also 920 into 839 and 81.

Clearly, you will see 775 is increased to 839 which correlates to the choice A's conclusion.

That's my thought. Let me know should you have any other idea or question. Thank you.

Admission rate means the rate you admit new patients. So for every 1000 beds there are in average 95 people who gets in the nursing home each year.

1) 1975-1985: Nursing home occupancy rates averaged 87%, admission rates averaged 95 admissions per 1000 beds per year

2) 1985-1988: Nursing home occupancy rates averaged 92%, admission rates averaged 81 admissions per 1000 beds per year.

If the statements above are true, which of the following conclusions can be most properly drawn?

A: The average length of time nursing-home residents stayed in nursing homes increased between 1985 and 1988.
- People stayed longer would cause the occupancy rate to go up, since they would occupy the beds they already occupied when they were first admitted.

B: The proportion of older people living in nursing homes was greater in 1988 than in 1975.
- This we can't be sure as well. We only know the percentage, not the actual figures.

C: Nursing home admission rates tend to decline whenever occupancy rates rise.
- Can't make the correlation based on two piece of data.

D: Nursing homes built prior to 1985 generally had fewer beds than did nursing homes built between 1985 and 1988.
- Can't be sure. The admission rate can drop for a variety of reasons - from having more beds, to less people inclined to stay in nursing homes

E: The more beds a nursing has, the higher its occupancy rate is likely to be.
- Can't make the correlation.

I'll take A.
