Inability to perform maximal Stair Climbing test before lung resection: a propensity score analysis on early outcome
2020Co-Authors: Eur J Cardiothorac, Alessandro Brunelli, Armando Sabbatini, Alessandro Borri, Aroldo Fianchini, Surg Salati, Rita Daniela Marasco, Francesco Xiume&apos, Kieran McmanusAbstract:Abstract Objective: The objective of the present study was to assess whether patients unable to perform a preoperative maximal Stair Climbing test had an increased incidence of morbidity and mortality after major lung resection compared to patients who were able to exercise. Methods: Three hundred and ninety one patients submitted to pulmonary lobectomy or pneumonectomy for lung cancer were analyzed. Forty-five of these patients were unable to perform a preoperative maximal Stair Climbing test for underlying comorbidities. Unadjusted and propensity score case matched comparisons were performed between patients who could and who could not perform a preoperative Stair Climbing test. Multivariable analyses were then performed to identify predictors of morbidity and mortality, and were validated by bootstrap bagging. Results: Patients who could not perform the Stair Climbing test had similar morbidity rates (31.1 vs. 35.6%, respectively, PZ0.7), but higher mortality rates (15.6 vs. 4.4%, respectively, PZ0.08) and deaths among complicated patients (50 vs. 12.5%, respectively, PZ0.025), compared to propensity score matched patients who could perform the Stair Climbing test. Logistic regression analyses showed that the inability to perform the Stair Climbing test was an independent and reliable predictor of mortality (PZ0.005) but not of morbidity (PZ0.2). Conclusions: Patients unable to perform a preoperative maximal exercise test had an increased risk of mortality after major lung resection. Half of these patients did not survive postoperative complications, due to their decreased aerobic reserve caused by physical inactivity which made them unable to cope with the increased oxygen demand.

performance at preoperative Stair Climbing test is associated with prognosis after pulmonary resection in stage i non small cell lung cancer
The Annals of Thoracic Surgery, 2012Co-Authors: Alessandro Brunelli, Michele Salati, Cecilia Pompili, Rossana Berardi, Paola Mazzanti, Azzurra Onofri, Stefano Cascinu, Armando SabbatiniAbstract:Background This investigation evaluated whether the performance at a preoperative symptom-limited Stair-Climbing test was a prognostic factor in resected pathologic stage I non-small cell lung cancer (NSCLC). Methods Observational analysis was performed on a prospective database that included 296 patients who underwent pulmonary lobectomy for pathologic stage T1 N0 or T2 N0 NSCLC (2000 to 2008). Patients who received induction chemotherapy were excluded. Survival was calculated by the Kaplan-Meyer method. The log-rank test was used to assess differences in survival between groups. The relationships between survival and baseline and clinical variables were determined by Cox multivariate analyses. Results Median follow-up was 43 months. The best cutoff associated with prognosis was an 18-meter Stair climb. Median (months) survival and 5-year survival of patients who climbed more than 18 meters were significantly longer than those who climbed less than 18 meters (97 vs 74; 77% vs 54%, p = 0.001). Cox regression model (hazard ratio) showed that Climbing more than 18 meters (0.5; p = 0.003), diffusion capacity of the lung for carbon monoxide (0.98; p = 0.02), and pT stage (1.8; p = 0.02) were independent prognostic factors. Patients who climbed less than 18 meters had increased deaths from cancer (24% vs 15%, p = 0.1) or other causes (19% vs 9%, p = 0.02). Conclusions Preoperative cardiopulmonary fitness is a significant prognostic factor in patients after resection for early-stage NSCLC. Interventions aimed at improving exercise tolerance can be useful to improve long-term prognosis after NSCLC operations.

performance at symptom limited Stair Climbing test is associated with increased cardiopulmonary complications mortality and costs after major lung resection
The Annals of Thoracic Surgery, 2008Co-Authors: Alessandro Brunelli, Majed Refai, Francesco Xiume, Michele Salati, Valeria Sciarra, Laura Socci, Armando SabbatiniAbstract:Background Exercise tests are increasingly used during preoperative evaluation before lung resection. This study assessed the association between performance at the symptom-limited Stair-Climbing test and postoperative cardiopulmonary morbidity, mortality, and costs after major lung resections. Methods As part of their routine preoperative evaluation, 640 patients who had lobectomy (n = 533) or pneumonectomy (n = 107) for lung cancer from January 2000 through April 2007 performed a preoperative symptom-limited Stair-Climbing test. Sensitivity/specificity analysis was used to identify the best cutoff values of altitude climbed (number of steps x height of the step in m) associated with outcome. Univariate and multivariate regression analyses (validated by bootstrap) were used to test associations between preoperative and operative factors and postoperative cardiopulmonary complications, mortality, and postoperative costs. Results The altitude reached at the Stair-Climbing test was reliably associated with increased cardiopulmonary complications (p = 0.04), mortality (p = 0.02), and costs (p Conclusions Performance at a maximal Stair-Climbing test was reliably associated with postoperative morbidity and mortality. We recommend the use of this simple and economic test in all lung resection candidates. Patients who perform poorly at the Stair-Climbing test should undergo a formal cardiopulmonary exercise test with measurement of oxygen consumption to optimize their perioperative management.

oxygen desaturation during maximal Stair Climbing test and postoperative complications after major lung resections
European Journal of Cardio-Thoracic Surgery, 2008Co-Authors: Alessandro Brunelli, Majed Refai, Francesco Xiume, Michele Salati, Rita Marasco, Valeria Sciarra, Laura Socci, Armando SabbatiniAbstract:Objective: Non-univocal conclusions have been published regarding the definition of oxygen desaturation in relation to postoperative outcome. We aimed to verify whether oxygen desaturation during a maximal Stair-Climbing test was associated with postoperative cardiopulmonary complications and to assess which definition of oxygen desaturation (oxygen saturation 4% with respect to rest level) discriminated better between complicated and uncomplicated patients. Methods: Five hundred and thirty-six patients performing a maximal Stair-Climbing test prior to major lung resection were analyzed. All patients performed the test on room air. Patients with and without cardiopulmonary complications were compared in terms of several preoperative and operative characteristics by univariate analysis, including the presenceof oxygen desaturation atpeak exercise(saturation 4%). Logisticregressionanalysiswas then performedand validated by bootstrap procedure to identify predictors of complications and to see whether the exercise oxygen desaturation retained its significancyaftermultivariableadjustment.Results:Twenty-sevenpatientshadanexerciseoxygensaturationbelow90%,butthisparameterwas not significantly associated with complications. Seventy-five patients experienced an exercise desaturation greater than 4%, which was a significant result associated with postoperative complications at univariate analysis (p = 0.008) (36% complication rate). After adjusting for age, ppoFEV1, ppoDLCO, type of operation, height reached at Stair-Climbing test and cardiac co-morbidity, a desaturation greater than 4% retained its significance at logistic regression and proved to be stable at bootstrap. Conclusions: A Stair-Climbing test is an intense constant workload exercise, challenging a large amount of muscle mass, and appears particularly appropriate to elicit oxygen desaturation, which in turn may be a reliable marker of deficits in the oxygen transport system. A desaturation >4% appears a better cut-off definition than a saturation level 4% at peak exercise. # 2007 European Association for Cardio-Thoracic Surgery. Published by Elsevier B.V.

Stair Climbing test predicts cardiopulmonary complications after lung resection
Chest, 2002Co-Authors: Alessandro Brunelli, Majed Refai, Michele Salati, Marco Monteverde, Alessandro Borri, Aroldo FianchiniAbstract:Study objective To evaluate the capability of the Stair Climbing test to predict cardiopulmonary complications after lung resection for lung cancer. Design A prospective cohort of candidates for lung resection. Spirometric assessment and the Stair Climbing test were performed the day before operation. Univariate and multivariate analyses were performed to identify predictors of postoperative complications. Setting Tertiary referral center. Patients A consecutive series of 160 candidates for lung resection with lung carcinoma from January 2000 through March 2001. Results At univariate analysis, the patients with complications were significantly older (p = 0.02), had a significantly lower FEV 1 percentage (p = 0.007) and predicted postoperative FEV 1 percentage (p = 0.01), had a greater incidence of a concomitant cardiac disease (p = 0.02), climbed a lower altitude at the Stair Climbing test (p < 0.0001), and had a lower calculated maximum oxygen consumption ( V ˙ o 2 max) [p = 0.03] and predicted postoperative V ˙ o 2 max (p = 0.006) compared to the patients without complications. At multivariate analysis, the altitude reached at the Stair Climbing test remained the only significant independent predictor of complications. Conclusions The Stair Climbing test is a safe and economical exercise test, and it was the best predictor of cardiopulmonary complications after lung resection.

testing messages to promote Stair Climbing at work
International Journal of Workplace Health Management, 2015Co-Authors: Erica Thomas, Anna Puig Ribera, Anna Senyemir, Sheila Greenfield, Frank F. EvesAbstract:Purpose – Worksites have been targeted as an important setting for physical activity interventions. A recent emphasis for health promoters is the use of point-of-choice interventions to encourage Stair Climbing at work. The purpose of this paper is to explore three point-of-choice campaigns to increase Stair Climbing at work. Design/methodology/approach – Ten focus groups and a rating task were conducted with 59 employees from a University and a University Hospital in the UK. Focus groups were structured around three messages and four prompts and sought to explore the motivational power of the resources, identify factors contributing to their effectiveness and provide recommendations to improve and optimize content. Benefits and barriers to Stair Climbing at work were also explored. Focus groups were recorded, transcribed and coded to identify key themes. Findings – Intra-personal factors health, motivation, social norms and time management influence Stair Climbing at work. Critically, extra-personal fact...

effectiveness and cost of two Stair Climbing interventions less is more
American Journal of Health Promotion, 2011Co-Authors: Ellinor K. Olander, Frank F. EvesAbstract:Abstract Purpose. The current study compared two interventions for promotion of Stair Climbing in the workplace, an information-based intervention at a health information day and an environmental intervention (point-of-choice prompts), for their effectiveness in changing Stair Climbing and cost per employee. Design. Interrupted time-series design. Setting. Four buildings on a university campus. Subjects. Employees at a university in the United Kingdom. Interventions. Two Stair-Climbing interventions were compared: (1) a stand providing information on Stair Climbing at a health information day and (2) point-of-choice prompts (posters). Measures. Observers recorded employees' gender and method of ascent (n = 4279). The cost of the two interventions was calculated. Analysis. Logistic regression. Results. There was no significant difference between baseline (47.9% Stair Climbing) and the Workplace Wellbeing Day (48.8% Stair Climbing), whereas the prompts increased Stair Climbing (52.6% Stair Climbing). The he...

Increasing Stair Climbing in a train station: The effects of contextual variables and visibility
Journal of Environmental Psychology, 2009Co-Authors: Frank F. Eves, Ellinor K. Olander, Gayle Nicoll, Anna Puig-ribera, Carl GriffinAbstract:Accumulation of physical activity during daily living is a current public health target that is influenced by the layout of the built environment. This study reports how the layout of the environment may influence responsiveness to an intervention. Pedestrian choices between Stairs and the adjacent escalators were monitored for 7 weeks in a train station (Birmingham, UK). After a 3.5 week baseline period, a Stair riser banner intervention to increase Stair Climbing was installed on two Staircases adjacent to escalators and monitoring continued for a further 3.5 weeks. Logistic regression analyses revealed that the visibility of the intervention, defined as the area of visibility in the horizontal plane opposite to the direction of travel (termed the isovist) had a major effect on success of the intervention. Only the largest isovist produced an increase in Stair Climbing. Additionally, Stair Climbing was more common during the morning rush hour and at higher levels of pedestrian traffic volume. The layout of the intervention site can influence responsiveness to point-of-choice interventions. Changes to the design of train stations may maximize the choice of the Stairs at the expense of the escalator by pedestrians leaving the station.

a workplace intervention to promote Stair Climbing greater effects in the overweight
Obesity, 2006Co-Authors: Frank F. Eves, Oliver J Webb, Nanette MutrieAbstract:Stair Climbing is a lifestyle physical activity that uses more calories per minute than jogging. This study tested an intervention designed to promote Stair Climbing in a workplace. Because previous studies provide only equivocal evidence of the effects of increased Stair Climbing in worksites, a formal comparison of the effects of the intervention on Stair ascent and descent was made. In a five-story public sector building, a 2-week baseline was followed by 6 weeks of an intervention involving a 23½- 16½-inch poster in the lobby, the same poster and six messages affixed to the Stair risers between floors, and an 11¾- 8¼-inch point-of-choice prompt at the elevators. Stair and elevator choices (n = 26,806) were videotaped throughout and subsequently coded for direction of travel, traveler's sex, and traveler's load. Weight status was coded using silhouettes beside the computer monitor. A significant effect of the intervention on Stair Climbing was greater in those coded as overweight (+5.4% ; odds ratio = 1.33) than in individuals of normal weight (+2.5% ; odds ratio = 1.12). Although Stair descent was more common than ascent, the intervention had similar effects for both directions of travel. Stair Climbing at work has few barriers and seems to be a type of physical activity that is acceptable to overweight individuals. The relatively weak effect of workplace interventions compared with results for public access Staircases may reflect uncontrolled effects such as the immediate availability of the elevator for the traveler.

an uphill struggle effects of a point of choice Stair Climbing intervention in a non english speaking population
International Journal of Epidemiology, 2006Co-Authors: Frank F. Eves, Rich S W MastersAbstract:BACKGROUND: Increases in lifestyle physical activity are a current public health target. Interventions that encourage pedestrians to choose the Stairs rather than the escalator are uniformly successful in English speaking populations. Here we report the first test of a similar intervention in a non-English speaking sample, namely the Hong Kong Chinese. METHODS: Travellers on the Mid-Levels escalator system in Hong Kong were encouraged to take the Stairs for their health by a point-of-choice prompt with text in Chinese positioned at the junction between the Stairs and the travelator. Gender, age, ethnic origin, and walking on the travelator were coded by observers. A 2 week intervention period followed 2 weeks of baseline monitoring with 57 801 choices coded. Specificity of the intervention was determined by contrasting effects in Asian and non-Asian travellers. RESULTS: There was no effect of the intervention on Stair Climbing and baseline rates (0.4%) were much lower than previous studies in Western populations (5.4%). Nonetheless, a modest increase in walking up the travelator, confined to the Asian population (OR = 1.12), confirmed that the intervention materials could change behaviour. CONCLUSIONS: It would be unwise to assume that lifestyle physical activity interventions have universal application. The contexts in which the behaviours occur, e.g. climate, may act as a barrier to successful behaviour change.
