Hello Friends,

I am facing challenge to get flagging variables to be derived.

Have data:

1. I want to create a flag whenever there is a rash on new body Part.

data want1 (drop = Body_Part);

set have;
by id Body_Part Rash_Date;
do i = 1 to while (scan(body_Part,i,",") ^= ' ');
n_body_Part = scan(body_Part,i, ' ');
output;
end;
run;

data want2;
set want1(rename = body_Part=n_body_Part);
by id body_Part Rash_date;
if first.bodyPart then A1 = "Y";
run;

Output will come like below:

2. I want to create another flag variable Repeat_Part when the hours difference between Rash date time and last drug adminstration date time for the same body Part if it is more than 50 hours then Repeat Part = "Y"

3. Once repeat_Part creted with Y when condition satisfies.. I want to further check the rashes which is coming at same body Part and its rash datetime difference not falling < 50 hours when compSRed with New_Body_Part="Y" or Repeat_Rash = Y its Drug adminstration date. If duration between repeated rash at same locaiton date time minus last rash (which has New_Body_Part = "Y" or Repeat_Part = "Y") hours differnce is more than 50 hours I want flag "Y" for RepeaTRash_gt50hours.

Notes to consider while creting Repeat_Part variable:
a.
If single body Part rash have multiple drug admistrations then take max of from the list drug adminstation (03MAY2022:21:00:00) into consideraiton to calculate hours difference.
vis.
KL 02MAY2022:18:17:00 03MAY2022:00:17:00
KL 02MAY2022:18:17:00 03MAY2022:21:00:00

It has multiple adminstraitons for same rash. so we hav to consider 03MAY2022:21:00:00 only this record in final dataset and calculaitons.

b. If multiple body Parts has same datetime rashes then we have to consider minimum of any one of the rash last drung adminstation datetime to calculate hours differnce with previous rash.

001 SR,FR,A UR 28NOV2021:16:42:00

This record has multple body Parts rash at same datetime.
First we have look for SR,FR,A UR drug adminstration datetime.
a. then take maximum of each body Part if either of the Part has multile adminstration for same rash (as explained in point 4)
b. then we will have one record for each rash with max drug adminstration datetime.
c. from this data take min drug adminstation of these 3 body Parts.
d. and calculate hour differnce between current rash date - previous last drug adminstration datetime (c point date).

4. My final dataset should have
8 variables:
1.ID
2.Body_Part
3.Rash_Date
4.New_Body_Part
5.Cur_rashdt_Minus_lst_inf_date_hours
6.Repeat_Part
7.currenTRash_date_minus_lasTRepeaTRash_eq_Y_durg adminstration date in hour.
8. RepeaTRash_gt_50hours.

If rashs happended at multple body Parts at same then it should come only in one record.

Re: want to handle multiple conditions. Please help

section 1) Creating a flag for each new instance of a rash on a different body part

Instead of doing a loop I would approach this with a first.

proc sort data=have;

by ID Body_Part Rash_Date;

run;

data want;

set have;

by ID Body_Part Rash_Date;

if first.Body_Part then New_Body_Part="Y";

run;

Section 2) creating flag variable Repeat_Part when the hours difference between Rash date time and last drug adminstration date time for the same body Part if it is more than 50 hours then Repeat Part = "Y". There can be multiple rashes at different body Parts.

For this section you would need the variable for last drug administration date-time and merge it with original dataset.

Then you can derive the number of hours between rash date-time and last drug administration date-time.

I would approach this with a macro for each body part.

%macro repeat_fl(body_part=);

data tmp;

set have;

if body_part="&body_part.";

if n(rash_date, drug_admin_date)=2 then hr_diff=intck('hour', rash_date, durg_admin_date);

if hr_diff>50 then repeat_part="Y";

run;

%mend repeat_fl;
