Question 1

You are responsible for calculating and reporting average length of stay (ALOS) for your hospital each month. This month, there were 92 discharges and the total discharge days equal 875. One of the patients discharged this month had a total of 428 discharge days, so the ALOS is distorted by this unusually long stay. In this situation, you should report an ALOS of

Accepted Answer

To account for the unusually long LOS of one patient, we need to remove their discharge days from the total discharge days before calculating the ALOS. Therefore, the correct calculation would be (875-428)/91 = 4.91 days. We should also make note of the fact that one patient had an unusually long stay and was removed from the calculation.

Question 2

Question 3

Question 4

Bayside Hospital has 275 adult beds, 30 pediatric beds, and 40 bassinets. In a nonleap year, inpatient service days were 75,860 for adults, 7,100 for pediatrics, and 11,800 for newborns. What was the average daily census for the year?

Accepted Answer

The average daily census is calculated by dividing the total inpatient service days by the number of days in the year. For adults and pediatrics, the total is 75,860 + 7,100 = 82,960. For newborns, it's 11,800. The total for all is 82,960 + 11,800 = 94,760. Dividing by 365 days gives an average daily census of 259.

Question 5

What was the percentage of occupancy for adults and pediatrics in February? Royal Palm Hospital has 500 beds and 55 bassinets. In February of a nonleap year, it reported the following statistics:

Accepted Answer

The answer of What was the percentage of occupancy for...

Question 6

In order to derive the total inpatient service days for any given day, you would need to

Accepted Answer

To calculate total inpatient service days, you add the number of same-day admits and discharges to the inpatient census, as these patients contribute to the total service days for that day.

Question 7

Looking more closely at the LOS for these patients. When you calculate the standard deviation the data, you would expect

Accepted Answer

When the dispersion (or variability) of the data is large, we would expect a large standard deviation. This is because the standard deviation measures how far the data points are from the mean, and if the data points are widely spread out, there will be larger differences between each point and the mean. Therefore, choice A is the best answer.

Question 8

All Women's Hospital reports the following statistics:  How many deliveries occurred?

Accepted Answer

The numbers in the stat report 11ec357f_2f65_011f_b39c_c3b3ccd91428_C1078_00 are difficult to decipher without additional information. However, based on the given answer choices, it is most likely that the number following "deliveries" in the report is 57.

Question 9

Patients in the pediatrics ward were studied to determine their favorite color. The survey results are listed below. The results of the favorite color study are reported in a

Accepted Answer

A frequency distribution is a summary of how often different values occur in a dataset, which is suitable for reporting survey results like favorite colors.

Question 10

Without even performing any complex calculations, you can get a quick, simple measure of dispersion in the LOS for yesterday's discharges by computing the

Accepted Answer

The range of the data set gives a quick and simple measure of dispersion by simply subtracting the smallest value from the largest value. This will show how spread out the data is without the need for complex calculations.

Question 11

What was the average length of stay at Royal Palm Hospital in February? Royal Palm Hospital has 500 beds and 55 bassinets. In February of a nonleap year, it reported the following statistics:

Question 13

Pasadena Bay Hospital reports an average LOS in February of 3.7 days with a standard deviation of 20. This tells us that

Accepted Answer

The standard deviation of 20 is quite large compared to the average LOS of 3.7 days, indicating a large variation in the length of stay among patients.

Question 14

A hospital reported the following statistics during a nonleap year. Calculate the percentage of occupancy for the entire year.

Accepted Answer

The answer of A hospital reported the following statistics during...

Question 15

Farside Hospital collected the following data on patients discharged on January 1, 2008. measure of central tendency would be most affected by Mallory's extremely long LOS?

Accepted Answer

The mean would be most affected by Mallory's extremely long LOS, as it takes into account all the values in the dataset and is sensitive to outliers. The median and mode, on the other hand, are less affected by extreme values. The variance measures the spread of the data and would not be directly affected by Mallory's long LOS.

Question 16

Jason collected data on the length of stay (LOS) for 10 patients and then determined the LOS as follows:  What is wrong with Jason's determination of the median?

Accepted Answer

The answer of Jason collected data on the length of...

Question 17

A patient admitted to the hospital on January 24 and discharged on February 9 has a length

Accepted Answer

The patient was admitted on January 24 and discharged on February 9. There are 16 days between these two dates, inclusive.

Question 18

The inpatient census at midnight is 67. Two patients were admitted in the morning; I died two hours later; the second patient was transferred to another facility that same afternoon. The inpatient service days for that day will be

Accepted Answer

The answer of The inpatient census at midnight is 67....

Question 19

Mr. McDonaldson was admitted to your hospital at 10:45 PM on January 1, 2008. He died at 4:22 AM on January 3, 2008. How many inpatient service days did Mr. McDonaldson receive?

Accepted Answer

Inpatient service days are calculated by counting the day of admission but not the day of discharge. Using this calculation, Mr. McDonaldson received 2 inpatient service days.

Question 20

The major purpose of random assignment in a clinical trial is to

Accepted Answer

Random assignment helps reduce selection bias in allocation of treatment. This means that the participants are allocated to different treatment groups in an unbiased manner, reducing the chances of any factors influencing the allocation process. This, in turn, helps ensure that any observed differences in outcomes are due to the treatment received and not any other factors.
