Hi SAS experts,

I have a dataset with monthly hospital onset infection rates for 38 months with intervention variable and also community onset infection rates. How do I perform an interrupted time series for hospital-onset infection rates over time adjusting for intervention and also community onset infection rates? Any help with this would be greatly appreciated. I have attached my excel data sheet and the SAS code. I came up with a couple of SAS codes for this, but not sure if I am correct. The first one is for simple model without adjusting for Community_rate. But the main goal is to evaluate the trend in the HOV_RAte over time after adjusting/ controlling for Community_Rate.

proc autoreg data=TimeSeries;

model HOV_Rate = Baseline_Trend Intervention Trend_Change /

method=ml nlag=5 backstep dwprob;

run;


* Need to adjust for community_rate;
proc autoreg data=TimeSeries;

model HOV_Rate = Community_Rate Baseline_Trend Intervention Trend_Change /

method=ml nlag=5 backstep dwprob;

run;

 

Thank you,

SM
