Calculate the death rates for each physician and the total for this quarter (round to two decimal places). Deaths are not included in the discharges.
answer
Muttiply tite 3 deaths by 100 and divide by the totalof deaths and discharges' (3x100)/(47+3)=6.00% (3x100)/(47+3) = 6.00% (ax100)t(107+41 = 3.60% (1 x100)/(9+1) = 10.00% (ax100)/(85+4) = 4.49o/o (6x100)r(119+6) = 4.80o/o (2x100)/(76+21 = 2.560/o (ax100)/(98+4) = 3.92o/o (3x100)/(55+3) = 5.17o/o (1 x100)/(117+11 = 0.85% (8x100)/(132+8) = 5.71o/o (36 x 100)/(845
question

question
Exercise 6.4 Using the information in the table below, calculate (round to two decimal places) the net death rate for each service and the total net death rate at Community Hospital for September. ln this exercise deaths are included in the discharges.
answer
For example, to find the net death rate for Medicine, multiply the number of deaths after 48 hours by 100 and then divide by the number of discharges including deaths after 48 hours. Because the number of discharges shown (265) includes all deaths, you have to subtract the 3 deaths under 48 hours. (7 x100)l(265 - 3) =7001262=2.670/o Medicine 265 3 7 (7 x 100)/(265 - 3) = 700/,262 = 2.670/o Surgery 237 1 2 (2 x 1001t(237 - 1) = 200/,236 = 0.85% Psychiatric 92 1 1 (1 x 100)/(92 - 1) = 100/91 = 1.10o/o Rehabilitation 42 1 3 (3 x 100)/(42 - 1) = 300141 = 7.32o/o Total 636 b 13 (13 x 100/(636 - 6) = 1300/630 = 2.06% For example, to find the net death rate for Medicine, multiply the number of
