RESUMO
BACKGROUND: The objective of this study was to investigate the impact of a program of major video-assisted surgery on care quality in a Unit of Thoracic Surgery. METHODS: A descriptive comparative study was conducted of 793 major thoracic procedures performed between 2009 and 2012. Quality indicators and hospital performance before [2009-2010] and after (2011 and 2012) the implementation of the program. RESULTS: The incidence of surgical complications decreased significantly from 6.32%/7.88% (2009/2010, respectively) to 1.87%/1.67% (2011/2012, respectively) [95% CI for 7.08% (4.20-9.96%); 95% CI for 1.76% (0.44-3.08%) P<0.001, respectively]. The mean hospital stay was reduced from 8.5/7.8 days in 2009/2010, respectively, to 6.3/5.8 days in 2011/2012, respectively. Mortality rates were 0.57%, 0.60%, 0.93% and 0.43% in 2009, 2010, 2011, and 2012, respectively (P=0.624, 95% CI: -0.6, 0.7). The percentages of emergency readmissions in 2009/2010 were 1.16%/1.23%, respectively vs. 2.80%/0.84% in 2011/2012. CONCLUSIONS: The implementation of the video-assisted thoracic surgery (VATS) program in the unit of Thoracic Surgery Care resulted in a significant improvement in care quality, with a reduction of length of hospital stay, but without any changes in mortality or the percentage of readmissions at 30 post-operative days.
