Implementation of a systematic tobacco treatment protocol in a surgical outpatient setting: a feasibility study.

Background: Smoking cessation programs started as late as 4 weeks before surgery reduce perioperative morbidity and death, yet outpatient clinic interventions are rarely provided. Our aim was to evaluate the feasibility of implementing a tobacco treatment protocol designed for an outpatient surgical setting. Methods: We completed a pre-post feasibility study of the implementation of a systematic, evidence-based tobacco treatment protocol in an outpatient colorectal surgery clinic. Outcomes included smoking prevalence, pre- and postimplementation smoker identification and intervention rates, recruitment, retention, smoking cessation and provider satisfaction. Results: Preimplementation, 15.5% of 116 surveyed patients were smokers. Fewer than 10% of surveyed patients reported being asked about smoking, and none were offered any cessation intervention. Over a 16-month postimplementation period, 1198 patients were seen on 2103 visits. Of these, 950 (79.3%) patients were asked smoking status on first visit and 1030 (86.0%) were asked on at least 1 visit. Of 169 identified smokers, 99 (58.6%) were referred to follow-up support using an opt-out approach. At 1-, 3- and 6-month follow-up, intention-to-quit rates among 78 enrolled patients were 24.4%, 22.9% and 19.2%, respectively. Postimplementation staff surveys reported that the protocol was easy to use, that staff would use it again and that it had positive patient responses. Conclusion: Implementation of our smoking cessation protocol in an outpatient surgical clinic was found to be feasible and used minimal clinic resources. This protocol could lead to increases in identification and documentation of smoking status, delivery of smoking cessation interventions and rates of smoking reduction and cessation.

Contexte: Les programmes d'abandon du tabagisme entamés jusqu'à 4 semaines avant une opération réduisent la morbidité et la mortalité périopératoires, mais les cliniques externes n'en proposent que rarement. L'étude visait à évaluer s'il est faisable d'appliquer un protocole de traitement du tabagisme pensé pour les milieux de soins chirurgicaux extrahospitaliers. Méthodes: Nous avons réalisé une étude de faisabilité pré- et postexpérimentale sur l'application d'un protocole de traitement systématique fondé sur des données probantes à une clinique externe de chirurgie colorectale. Les résultats à l'étude étaient les suivants : prévalence du tabagisme, identification des fumeurs et taux d'intervention avant et après la mise en place du protocole, recrutement, rétention, abandon du tabagisme et satisfaction des fournisseurs. Résultats: Au départ, 15,5 % des 116 patients sondés fumaient. Moins de 10 % des répondants avaient été questionnés sur leur statut tabagique, et aucun ne s'était vu proposer un programme d'abandon. Au cours des 16 mois suivant la mise en place du protocole, 1198 patients ont été rencontrés dans le cadre de 2103 consultations. Parmi eux, 950 (79,3 %) ont été interrogés sur leur statut tabagique à la première rencontre, et 1030 (86 %) l'ont été au moins 1 fois. Des 169 fumeurs identifiés, 99 (58,6 %) ont été orientés vers un programme de soutien selon une approche de consentement présumé. Après 1 mois, 24,4 % des 78 patients participants étaient déterminés à arrêter de fumer; 22,9 % l'étaient toujours après 3 mois, et 19,2 % après 6 mois. Les sondages menés a posteriori auprès du personnel indiquent que le protocole est facile à utiliser, que les employés s'en serviraient de nouveau, et que les patients l'ont accueilli favorablement. Conclusion: Il a été possible de mettre en place notre protocole d'abandon du tabagisme à une clinique externe de chirurgie, et ce en employant un minimum de ressources cliniques. Le protocole pourrait permettre de connaître et de consigner davantage de statuts tabagiques, d'orienter un plus grand nombre de fumeurs vers les programmes d'abandon et d'accroître les taux de réduction et d'abandon du tabagisme.

A Cross-Sectional Survey to Determine the Prevalence of Burnout Syndrome Among Anesthesia Providers in Zambian Hospitals.

BACKGROUND: Burnout is a psychological syndrome that results from chronic exposure to job stress. It is defined by a triad of emotional exhaustion, depersonalization, and reduced personal accomplishment. In research, mostly from high-income countries, burnout is common in health care professionals, especially in anesthesiologists. Burnout can negatively impact patient safety, the physical and mental health of the anesthetist, and institutional efficiency. However, data on burnout for anesthesia providers in low- and middle-income countries are poorly described. This study sought to determine the prevalence of burnout syndrome among all anesthesia providers (physician and nonphysician) working in Zambian hospitals and to determine which sociodemographic and occupational factors were associated with burnout. METHODS: A questionnaire was sent to all Zambian anesthesia providers working in private and public hospitals. The questionnaire assessed burnout using the Maslach Burnout Inventory Human Services Survey, a validated 22-item survey widely used to measure burnout among health professionals. Sociodemographic and occupational factors postulated to be associated with burnout were also assessed. RESULTS: Surveys were distributed to all 184 anesthesia providers in Zambia; 160 were returned. This resulted in a response rate representing 87% of all anesthesia providers in the country. Eighty-six percentage of respondents were nonphysician anesthesia providers. Burnout was present in 51.3% (95% confidence interval [CI], 43.2-59.2) of participants. Logistic regression analysis revealed that "not having the right team to carry out work to an appropriate standard" (odds ratio, 2.91, 95% CI, 1.33-6.39; P = .008), and "being a nonphysician" (odds ratio, 3.4, 95% CI, 1.25-12.34; P = .019) were significantly associated with burnout in this population. CONCLUSIONS: In a cross-sectional survey of anesthesia providers in Zambia, >50% of the respondents met the criteria for burnout. The risk was particularly high among nonphysician providers who typically work in isolated rural practice. Efforts to decrease burnout rates through policy and educational initiatives to increase the quantity and quality of training for anesthesia providers should be considered.

Cerebral Oximetry Monitoring to Maintain Normal Cerebral Oxygen Saturation during High-risk Cardiac Surgery: A Randomized Controlled Feasibility Trial.

BACKGROUND: Cerebral oxygen desaturation during cardiac surgery has been associated with adverse perioperative outcomes. Before a large multicenter randomized controlled trial (RCT) on the impact of preventing desaturations on perioperative outcomes, the authors undertook a randomized prospective, parallel-arm, multicenter feasibility RCT to determine whether an intervention algorithm could prevent desaturations. METHODS: Eight Canadian sites randomized 201 patients between April 2012 and October 2013. The primary outcome was the success rate of reversing cerebral desaturations below 10% relative to baseline in the intervention group. Anesthesiologists were blinded to the cerebral saturation values in the control group. Intensive care unit personnel were blinded to cerebral saturation values for both groups. Secondary outcomes included the area under the curve of cerebral desaturation load, enrolment rates, and a 30-day follow-up for adverse events. RESULTS: Cerebral desaturations occurred in 71 (70%) of the 102 intervention group patients and 56 (57%) of the 99 control group patients (P = 0.04). Reversal was successful in 69 (97%) of the intervention group patients. The mean cerebral desaturation load (SD) in the operating room was smaller for intervention group patients compared with control group patients (104 [217] %.min vs. 398 [869] %.min, mean difference, -294; 95% CI, -562 to -26; P = 0.03). This was also true in the intensive care unit (P = 0.02). There were no differences in adverse events between the groups. CONCLUSIONS: Study sites were successful in reversal of desaturation, patient recruitment, randomization, and follow-up in cardiac surgery, supporting the feasibility of conducting a large multicenter RCT.

Peripheral nerve block anesthesia/analgesia for patients undergoing primary hip and knee arthroplasty: recommendations from the International Consensus on Anesthesia-Related Outcomes after Surgery (ICAROS) group based on a systematic review and meta-analysis of current literature.

BACKGROUND: Evidence-based international expert consensus regarding the impact of peripheral nerve block (PNB) use in total hip/knee arthroplasty surgery. METHODS: A systematic review and meta-analysis: randomized controlled and observational studies investigating the impact of PNB utilization on major complications, including mortality, cardiac, pulmonary, gastrointestinal, renal, thromboembolic, neurologic, infectious, and bleeding complications.Medline, PubMed, Embase, and Cochrane Library including Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials, NHS Economic Evaluation Database, were queried from 1946 to August 4, 2020.The Grading of Recommendations Assessment, Development, and Evaluation approach was used to assess evidence quality and for the development of recommendations. RESULTS: Analysis of 122 studies revealed that PNB use (compared with no use) was associated with lower ORs for (OR with 95% CIs) for numerous complications (total hip and knee arthroplasties (THA/TKA), respectively): cognitive dysfunction (OR 0.30, 95% CI 0.17 to 0.53/OR 0.52, 95% CI 0.34 to 0.80), respiratory failure (OR 0.36, 95% CI 0.17 to 0.74/OR 0.37, 95% CI 0.18 to 0.75), cardiac complications (OR 0.84, 95% CI 0.76 to 0.93/OR 0.83, 95% CI 0.79 to 0.86), surgical site infections (OR 0.55 95% CI 0.47 to 0.64/OR 0.86 95% CI 0.80 to 0.91), thromboembolism (OR 0.74, 95% CI 0.58 to 0.96/OR 0.90, 95% CI 0.84 to 0.96) and blood transfusion (OR 0.84, 95% CI 0.83 to 0.86/OR 0.91, 95% CI 0.90 to 0.92). CONCLUSIONS: Based on the current body of evidence, the consensus group recommends PNB use in THA/TKA for improved outcomes. RECOMMENDATION: PNB use is recommended for patients undergoing THA and TKA except when contraindications preclude their use. Furthermore, the alignment of provider skills and practice location resources needs to be ensured. Evidence level: moderate; recommendation: strong.

Prevalence of symptoms at the end of life in an acute care hospital: a retrospective cohort study.

BACKGROUND: There is currently debate over the benefits and harms of physician-assisted death. One of the factors influencing this debate is concern about symptoms in the days before death. The objective of this study was to describe the frequency of symptoms before death and determine patient characteristics associated with these symptoms. METHODS: We reviewed the medical record of every patient who died at a multisite academic teaching hospital over a 3-month period. We determined the number of episodes of pain, dyspnea, agitation and nausea during the final 48 hours of life and assessed the patient and encounter characteristics associated with 2 or more episodes of symptoms. RESULTS: A total of 480 patients died during the study period. Of these patients, 29.2% (140/480) had 2 or more symptoms in the final 48 hours of life. Higher Elixhauser comorbidity scores (relative risk [RR] 1.35, 95% confidence interval [CI] 1.23-1.49), having a family doctor (RR 2.33, 95% CI 1.02-5.38), being admitted to the medical oncology service (RR 1.51, 95% CI 1.11-2.05) and having a documented order for no resuscitation written early during the stay in hospital (RR 1.38, 95% CI 1.01-1.89) were independently associated with symptoms. Admission to intensive care was associated with fewer symptoms (RR 0.39, CI 95% 0.19-0.80). INTERPRETATION: Symptoms are common in the final 48 hours of life, particularly in patients with multimorbidity who want limitations on the aggressiveness of their care. An integrated palliative approach is needed for select at-risk patients.
