PURPOSE:  To split DRGs 79-80 hospitalizations into two populations that differ for mean length of stay (LOS): patients with tuberculosis (TB) and patients with respiratory infection and inflammations other than TB (NTB) in principal diagnosis.

METHODS:  Data are from PneumoSTAR project database, developed in Italy since 1999 by A.I.P.O (Associazione Italiana Pneumologi Ospedalieri) and QUBIsoft (236,000 discharge forms, 90 Italian Respiratory Units). We used data from 120,000 discharge forms, relative to years 2001-2002-2003.

RESULTS:  In 2001, DRG79 (n=1040, 2.7% of all DRGs) counted 336 TB (32.3%) and LOS=15.8 days; 704 NTB (67.7%) and LOS=16.9 : (LOS p=0.33) DRG80 (n=646, 1.7%) counted 326 TB (50.5%) and LOS=19.4; 320 NTB (49.5%) and LOS=12.9: (p<0.01). In TB, LOS is different between DRGs 79-80 (p=0.02); in NTB, the same but in the opposite way (p<0.01). In 2002, DRG79 (n=982, 2.9%) counted 349 TB (35.5%) and LOS=17.2; 633 NTB (64.5%) and LOS= 5.3: (p=0.1). DRG80 (n=499, 1.5%) counted 253 TB(50.7%) and LOS=15.4; 246 NTB(49.3%) and LOS=2.7: (p=0.019). In NTB, LOS is different between the two DRGs (p<0.01); it isn’t so in TB (p=0.18). In 2003, DRG79 (n=710, 2.7%) counted 189 TB (26.6%) and LOS=15.8; 521 NTB (73.4%) and LOS=15.9: (p=0.96). DRG80 (n=339,1.3%) counted 135 TB (39.8%) and LOS=15.5; 204 NTB (60.2%) and LOS=12.3: (p=0.02). In NTB, LOS is different between the two DRGs (p<0.01); it isn’t so in TB (p=0.87).

CONCLUSION:  In 2001-2002-2003 both DRGs 79-80 produced by TB, hospital admission is decreased. In DRG80, TB cases are less than in DRG79: lower comorbidity can be explained by the younger age in TB patients (55.9 years) versus NTB patients (65.3 years).

CLINICAL IMPLICATIONS:  In DRG79, TB and NTB don’t differ in term of LOS, while this difference can be observed in DRG80. Moreover, TB LOS is not different in DRGs 79-80: it may means that in TB, the pathology itself determines LOS, and not the comorbidity. On the contrary, comorbidity has an important role on LOS in presence of respiratory infection and inflammations other than TB.
