Variable definition

Patient outcome
SHR	Standardized Hospitalization Ratio, calculated as the actual observed no. of hospitalization admissions for the patients at a facility divided by the expected no. of admissions for the same patients after risk adjusted
Clinical processes
URR65	Indicates the percentage of patients who had URR greater than or equal to 65 per cent
Kt/V1.2	Indicates the percentage of adult HD patients with Kt/V greater than or equal to 1.2
Hgb10	Indicates the percentage of patients who had average Hgb less than 10.0 g/dL
Facility characteristics
Chain Type	Indicates a facility's affiliation status; 1 = affiliate to a chain, 0 = otherwise
Own Type	Indicates a facility's for-profit status; 1 = for-profit, 0 = not for-profit
Treatment/Patient	Indicates the number of dialysis treatments offered per patient
Urban	Indicates a facility's geographic location; 1 = urban, 0 = rural
Cost/Patient	Indicates the average composite cost per treatment in US$1,000
Local Market Share	Indicates the market concentration in terms of patient number at the 3-digit-level zip code
Practice pattern
AVF Usage	Indicates the percentage of adult patients who received treatment through an arterial venous fistula (AVF)
Catheter Usage	Indicates the percentage of adult patients who had a catheter (tube) left in a vein longer than 90 days for their regular HD treatments
Dialyzer Reuse	Indicates whether a facility reuses dialyzers; 1 = reuse, 0 = no reuse
Nurse-To-Patient ratio	Indicates the number of nurses per patient
Physician-To-Patient ratio	Indicates the number of physicians per patient
Station-To-Patient ratio	Indicates the number of dialysis stations per patient
PD	Indicates whether a facility offers in-center peritoneal dialysis (PD); 1=offer, 0=no offer
Late Shift	Indicates whether or not the facility has a shift starting at 5:00 p.m. or later; 1=offer, 0=no offer

Notes:

SHR is from Y2013, while other facility characteristics and practice patterns are from Y2012. Both periods of URR65, Kt/V1.2 and Hgb10 are used
