Preoperative smoking status was not observed to be associated with postoperative mortality , cardiovascular complications , bleedings , anastomotic leakage , or allograft rejection .
CONCLUSIONS Preoperative smoking was found to be associated with an increased risk of the following postoperative complications : general morbidity , wound complications , general infections , pulmonary complications , neurological complications , and admission to the intensive care unit
OBJECTIVE To systematic ally review and summarize the evidence of an association between preoperative smoking status and postoperative complications elaborated on complication type .
BACKGROUND The conclusions of studies examining the association between preoperative smoking and postoperative complications are inconsistent , thus there is a need for a review and meta- analysis to summarize the existing evidence .
Influence of smoking and alcohol consumption on admissions and duration of hospitalization.
BACKGROUND Previous studies have linked smoking and alcohol consumption to a considerable disease burden and large healthcare expenditures . However , findings from studies based on individual level data are sparse and inconclusive . Our objective was to assess the association between alcohol consumption , smoking and patterns of hospitalization , defined as admission and duration of hospitalization . METHODS The study was based on 12 698 men and women , aged 20 years or more , enrolled in the Copenhagen City Heart Study . We related  smoking and alcohol  to hospital admission from any cause , smoking- and alcohol-related diseases and duration of hospitalization in a two-part r and om effects model . RESULTS Smoking status was strongly associated with admission and duration of hospitalization . For smoking-related admissions , odds ratios ( OR ) of 2.77 ( 95 % CI 2.13 - 3.59 ) in men and 6.30 ( 95 % CI 4.80 - 8.26 ) in women were observed among smokers of > 20 g/day compared to never-smokers . For any admission ( excl . smoking-related causes ) , corresponding ORs were 1.32 ( 95 % CI 1.15 - 1.51 ) and 1.80 ( 95 % CI 1.58 - 2.06 ) , respectively . In men , a U-shaped association between alcohol consumption and risk of admission was found , both regarding any admission and admissions due to alcohol-related diseases . Alcohol was associated with alcohol-related admissions in women but not with duration of hospitalization . CONCLUSIONS Smoking was associated with increased risk of hospital admission and duration of hospitalization . A U-shaped relation was observed for alcohol consumption and risk of hospitalization in men , but no effect on duration was observed . In women , however , alcohol consumption was only vaguely associated with admission and duration of hospitalization
