OBJECTIVES: Non-Communicable Diseases (NCDs), are difficult to measure, so we used a Chronic Conditions (CC) table in a discharge registry to obtain them.  METHODS: In a 1 year output of 3 hospitals, a CC (MCRR, 2006; 63: 327 - 346) table was used. A Pareto rank of first 10 CCS with CC (+) in primary diagnosis (Dx1) and secondary diagnosis (Dx2) among ≥19 yrs old, costs, Clinical Classification Software-CCS single level-SL groupers (2009) (#CCS [descriptive term]), average length of stay (ALOS), total costs (CT$) mean and median per discharge cost ($), (25P-75P-percentiles), in international dollars PPP, (1Arg$ = 1.608 I$ PPP, 2008) were obtained.  CT$ of all CC burden is reported.  RESULTS: Among ≥ 19 years, 17169 Dx1 with CC (+) (37,76%), had CT$: I$ 243 893 494 (39,36% of hospital cost) and ($): I$ 14 473,04. 15 102 discharges had 1 or more CC(+) in Dx2 (32,97%), with a CT:I$ PPP 216 158 768, (1,86% of discharges not costed). The top 10 CCS with CC where 7489 discharges, a 16,35% of total discharges ≥19 years old, CT$: I$ 109 896 918. The first 10 CCS of the pareto ranking, mean age 42 years (SD 30,45 yrs), an ALOS was 3,54 (SD 5,07) days, with a ($): I$ 10 560,92 (SD I$ 18 101,73), a median cost of I$ 4057,56 (25-75 percentiles I$ 1022,97-8250,84). The CCS #45 [Maintenance chemotherapy; radiotherapy] of which 100% was CC (+) was ranked #1, followed by CCS #149 [Biliary tract disease], of which 19,34% was CC(+). In hospital mortality of CC (+) in Dx1 was 817 deaths (4,75%).    CONCLUSIONS: CC table obtained the Burden of CC in discharges at 38% of total costs. Behavior of CC in CCS are compatible with each condition. Future studies should address generalizability of results, accuracy of Dx2 coding and co-morbidity.
