Hello,

 

I have a project that I want to create an index for adherence index to antiretroviral therapy (ART).

 

Adherence questionnaire composed three questions: dose, instruction and schedule.

a. dose is binary answer y/n

b. instruction:

b1. is binary answer y/n

b2. is ordinal answer 1-5

c. schedule is ordinal answer 1-5

 

Anyone can help is greatly appreciated and thanks in advance.

 

Regards,

 

Phan S.

That's not what most programmers would refer to as an index. 

Can you explain further what you're referring to as an 'index'? Perhaps posting sample input and expected output may be helpful.

Hello Reeza,

I am sorry - was not feel well. 

I attached a file that contains four questions to evaluate 100% adherence to medications.

 

The index will be used to see if it correlates with: 

a) Length of treatment

b) Length of HIV diagnosis

c) CD4 cells counts after 6 months of treatment 

d) Viral loads after 6 months of treatment 

 

Thank you.

Hello Reeza,

 

I attached a file - a researcher used what it called VACS Index to predict HIV mortality.

The VACS Index contains: age, CD4 cells, Viral loads, Hemoglobin, FIB-4 and renal function. 

I have no idea how they created. For instance, age. The index were 0 if <50 year; 12 if 50-64 year and 65 if 65+ year.

 

Thank you.

You have to be more clear about what you want to do.

 

SAS Indexes is something completely different from what you want.

Thank your for your input.

I just replied to Reeza.
