Recently hospitalized residents with pressure ulcers (risk adjusted)

Exclusions: Patients satisfying the following condition:
1.M2a is missing on the 14-day assessment [t
2. M2a is missing on the 5-day assessment [t-1] and M2a shows presence of pressure ulcers on the 14-day assessment (M2a=1,2,3, or 4.
3. The Patient is in a facility with a Post Acute Care Admission Sample size of 0 (i.e., there are no SNF PPS 5-day assessments with AA8b =1 in the facility over the previous 12 months)

Covariates:
1. Indicator of history of unresolved pressure ulcer on the SNF PPS 5-day assessment. Covariate =1 if M3 =1.
Covariate =0 if M3 =0.
2. Indicator of requiring limited or more assistance in bed mobility on the SNF PPS 5-day assessment:
Covariate = 1 if G1a(A) = 2,3,4, or8.
Covariate = 0 if G1a(A) =0 or 1.
3. Indicator of bowel incontinence at least one/week on the SNF PPS 5-day assessment:
Covariate =1 if H1a 2,3, or 4.
Covariate =0 if H1a = 0 or 1.
4. Indicator of diabetes or peripheral vascular disease on the SNF PPS 5-day assessment:
Covariate =1 if I1a checked (value 1) or I1j checked (value 1).
Covariate =0 if I1a not checked (value 0) and I1j not checked (value 0).
5. Indicator of Low Body Mass Index (BMI) on the SNF PPS 5-day assessment:
Covariate = 1 if BMI >=12 and =19.
Covariate = 0 if BMI > 19 and = 40.
Where: BMI = weight(kg)/height2 (m2) = ((K2b*0.45)/(((K2a)*.0254)^2))

(Note: An implausible BMI value 12 or >40 will be treated as a missing value on this covariate.
