To evaluate the influence of preoperative abstinence on postoperative outcome in alcohol misusers with no symptoms who were drinking the equivalent of at least 60 g ethanol/day.
                Randomised controlled trial. Setting: Copenhagen, Denmark.
                42 alcoholic patients without liver disease admitted for elective colorectal surgery.
                Withdrawal from alcohol consumption for 1 month before operation (disulfiram controlled) compared with continuous drinking.
                Postoperative complications requiring treatment within the first month after surgery. Perioperative immunosuppression measured by delayed type hypersensitivity; myocardial ischaemia and arrhythmias measured by Holter tape recording; episodes of hypoxaemia measured by pulse oximetry. Response to stress during the operation were assessed by heart rate, blood pressure, serum concentration of cortisol, and plasma concentrations of glucose, interleukin 6, and catecholamines.
                The intervention group developed significantly fewer postoperative complications than the continuous drinkers (31% v 74%, P=0.02). Delayed type hypersensitivity responses were better in the intervention group before (37 mm2 v 12 mm2, P=0.04), but not after surgery (3 mm2 v 3 mm2). Development of postoperative myocardial ischaemia (23% v 85%) and arrhythmias (33% v 86%) on the second postoperative day as well as nightly hypoxaemic episodes (4 v 18 on the second postoperative night) occurred significantly less often in the intervention group. Surgical stress responses were lower in the intervention group (P</=0.05).
                One month of preoperative abstinence reduces postoperative morbidity in alcohol abusers. The mechanism is probably reduced preclinical organ dysfunction and reduction of the exaggerated response to surgical stress. To determine whether an intervention with smoking cessation starting 4 weeks before general and orthopedic surgery would reduce the frequency of postoperative complications.
                Complications are a major concern after elective surgery and smokers have an increased risk. There is insufficient evidence concerning how the duration of preoperative smoking intervention affects postoperative complications.
                A randomized controlled trial, conducted between February 2004 and December 2006 at 4 university-affiliated hospitals in the Stockholm region, Sweden. The outcome assessment was blinded. The follow-up period for the primary outcome was 30 days. Eligibility criteria were active daily smokers, aged 18 to 79 years. Of the 238 patients assessed, 76 refused participating, and 117 men and women undergoing surgery for primary hernia repair, laparoscopic cholecystectomy, or a hip or knee prosthesis were enrolled.
                Smoking cessation therapy with individual counseling and nicotine substitution started 4 weeks before surgery and continued 4 weeks postoperatively. The control group received standard care. The main outcome measure was frequency of any postoperative complication.
                An intention-to-treat analysis showed that the overall complication rate in the control group was 41%, and in the intervention group, it was 21% (P = 0.03). Relative risk reduction for the primary outcome of any postoperative complication was 49% and number needed to treat was 5 (95% CI, 3-40). An analysis per protocol showed that abstainers had fewer complications (15%) than those who continued to smoke or only reduced smoking (35%), although this difference was not statistically significant.
                Perioperative smoking cessation seems to be an effective tool to reduce postoperative complications even if it is introduced as late as 4 weeks before surgery. Smokers are at higher risk of cardiopulmonary and wound-related postoperative complications than non-smokers. Our aim was to investigate the effect of preoperative smoking intervention on the frequency of postoperative complications in patients undergoing hip and knee replacement.
                We did a randomised trial in three hospitals in Denmark. 120 patients were randomly assigned 6-8 weeks before scheduled surgery to either the control (n=60) or smoking intervention (60) group. Smoking intervention was counselling and nicotine replacement therapy, and either smoking cessation or at least 50% smoking reduction. An assessor, who was masked to the intervention, registered the occurrence of cardiopulmonary, renal, neurological, or surgical complications and duration of hospital admittance. The main analysis was by intention to treat.
                Eight controls and four patients from the intervention group were excluded from the final analysis because their operations were either postponed or cancelled. Thus, 52 and 56 patients, respectively, were analysed for outcome. The overall complication rate was 18% in the smoking intervention group and 52% in controls (p=0.0003). The most significant effects of intervention were seen for wound-related complications (5% vs 31%, p=0.001), cardiovascular complications (0% vs 10%, p=0.08), and secondary surgery (4% vs 15%, p=0.07). The median length of stay was 11 days (range 7-55) in the intervention group and 13 days (8-65) in the control group.
                An effective smoking intervention programme 6-8 weeks before surgery reduces postoperative morbidity, and we recommend, on the basis of our results, this programme be adopted. We tested an intervention to help smokers abstain (fast) from smoking before surgery, maintain abstinence postoperatively, and achieve long-term cessation. A randomized experiment included 237 patients admitted for presurgical assessment who smoked. The intervention included counseling and nicotine replacement therapy. Treatment group participants (73.0%) were more likely to fast than were controls (53.0%): chi(2)(1, N = 228) = 8.89, p =.003, and more likely to be abstinent 6 months after surgery (31.2% vs. 20.2%). There was no significant difference in the abstinence rates at 12 months after surgery, chi(2)(1, N = 169) <.001, p = 1.00. Encouraging patients to fast from smoking before surgery and postoperative support are efficacious ways to reduce preoperative and immediate post-operative tobacco use.
                Copyright 2004 Wiley Periodicals, Inc. Smokers have a higher risk of complicated tissue and wound healing after surgery than nonsmokers. We tested the hypothesis that short-term pre-operative cessation of smoking in colorectal surgery decreases the incidence of postoperative tissue and wound complications.
                From February 1998 to March 2001, 60 patients, who smoked daily, undergoing colorectal resection were randomly assigned 2-3 weeks before scheduled surgery to either abstinence from smoking, counselling and nicotine replacement therapy or maintenance of daily smoking habits. Postoperative tissue and wound complications necessitating surgical or medical treatment were evaluated at discharge and 30 days after surgery by blinded outcome assessment.
                In the pre-operative period of 15 days (8-24) (median, interquartile range (IQR)), 89% of the patients in the intervention group vs. 13% in the control group abstained from smoking or reduced by more than half (P < 0.05). In the postoperative period of 11 days (10-13), the corresponding figures were 92% and 50%, respectively (P < 0.05). Postoperative tissue and wound complications occurred in 33% (9 of 27) of the patients in the intervention group compared to 27% (8 of 30) in the control group (NS). Likewise, no difference in overall postoperative complication rate was found between the groups.
                Short-term cessation of smoking does not reduce the risk of complicated tissue and wound healing or other complications in colorectal surgery. Smokers are more prone to develop postoperative complications. Smoking cessation intervention beginning 4-8 weeks prior to surgery improves the postoperative outcome. Cancer patients, however, often undergo surgery less than 4 weeks after diagnosis. The primary objective of this study was therefore to examine if a brief smoking cessation intervention shortly before breast cancer surgery would influence postoperative complications and smoking cessation.
                A randomized controlled multicentre trial with blinded outcome assessment conducted at 3 hospitals in Denmark. One hundred and thirty patients were randomly assigned to brief smoking intervention (n = 65) or standard care (n = 65). The intervention followed the principles of motivational interviewing and included personalized nicotine replacement therapy aimed at supporting smoking cessation from 2 days before to 10 days after surgery.
                The overall postoperative complication rate (including seroma requiring aspiration) was 61% in both groups risk ratio (RR) 1.00 (95% CI 0.75-1.33). The wound complication rate was 44% versus 45%. The effect on perioperative smoking cessation was modest, 28% intervention versus 11% control group patients, RR 2.49 (95% CI 1.10-5.60). There was no effect on smoking cessation at 12 months, 13% versus 9%.
                Brief smoking intervention administered shortly before breast cancer surgery modestly increased self-reported perioperative smoking cessation without having any clinical impact on postoperative complications. The study adds to the body of evidence indicating that brief intervention has no clinical importance for surgical patients in regard to postoperative morbidity. Future studies should be designed to determine the optimal time of smoking cessation before surgery. To assess the effects of a smoking cessation program for recovering alcoholics on use of alcohol, tobacco and illicit drugs after discharge from residential treatment.
                A randomized community intervention trial design was employed in which 12 residential drug treatment centers in Iowa, Kansas and Nebraska were matched and then randomly assigned to the intervention or control condition.
                Approximately 50 adult residents (inpatients) from each site were followed for 12 months after treatment discharge.
                Participating residents in the six intervention centers received a 4-part, individually tailored, smoking cessation program while those in the six control sites received usual care.
                Both moderate and heavy drinking rates were reduced in the intervention group. Intervention site participants were significantly more likely than controls to report alcohol abstinence at both the 6-month (OR = 1.59, 95%CI: 1.09-2.35) and 12-month assessment (OR = 1.84, 95%CI: 1.28-2.92). Illicit drug use rates were comparable. Effect of the intervention on tobacco quit rates was not statistically significant.
                Counseling alcoholics in treatment to quit smoking does not jeopardize the alcohol recovery process. However, low-intensity tobacco interventions are unlikely to yield high tobacco quit rates. This randomized clinical trial was designed to test the efficacy of intensive versus brief smoking cessation interventions for hospital patients. The interventions included advice and pamphlets for Brief and bedside counselling, take-home materials, and 7 post-discharge telephone counselling calls over 2 months for Intensive. Confirmed 1-year abstinence was 28% for Intensive (85/301) and 24% for Brief (76/315). Abstinence was significantly higher for patients who did not use pharmacotherapy (36%) versus those who did (16%) and for patients with CVD (40%) versus other diagnoses (20%). Because this was a replication trial, benchmarks for planning can be suggested: 12% to 15% recruitment of identified smokers, 90% plus completion for Intensive, 15% drop-out, and 75% abstinence corroboration. The results consolidate findings for general inpatients, including expected absolute abstinence and treatment outcomes, the effect of CVD patients on outcomes, the reproducibility of high abstinence in a universal health-care system, and the need for more research to inform practice. Preoperative smoking intervention programmes reduce post-operative complications in smokers. Little is known about the long-term effect upon smoking cessation.
                To discover long-term quit rates and the reasons behind successful cessation.
                101 one of 120 smokers, randomised to smoking intervention or no intervention before hip and knee surgery, completed questionnaires concerning smoking after 1 year. We selected representative men and women for focus group interviews.
                Significantly more patients from the intervention group abstained from smoking for 1 year post-operatively [13 in 60 patients (22%) vs 2 in 60 (3%), P < 0.01]. Sex (male), low nicotine dependency, non-smoking spouse and preoperative smoking intervention were related to smoking cessation. All patients gave the same reasons for smoking cessation: improved health and saving money. Follow-up for 5 years showed 17% of the controls and 8% in the intervention group (P = 0.42) had died.
                The intervention group had a significantly higher quit rate 1 year after a preoperative smoking cessation programme.
Based on the finding of two studies, it appears that intensive preoperative alcohol cessation interventions, including pharmacological strategies for relapse prophylaxis and withdrawal symptoms, may significantly reduce postoperative complication rates. No effect was found on mortality rates and length of stay.
The effect of preoperative alcohol cessation intervention should be further explored in an effort to reduce the adverse effect of alcohol use on surgical outcomes. The number needed to screen to identify eligible patients for alcohol intervention studies in surgical settings seems to be extremely high. This may indicate that these studies are difficult to perform. Nevertheless, timing, duration and intensity of alcohol cessation interventions need to be subject to further investigation.
