The preoperative level of physical activity is associated to the postoperative recovery after elective cholecystectomy - A cohort study

Responsiveness and minimal clinically important difference of the 6-minute walk distance in patients undergoing colorectal cancer surgery

PURPOSE

This study aimed to clarify the responsiveness and minimal clinically important difference (MCID) of the 6-minute walk distance (6MWD) from before and 1 week after surgery in patients with colorectal cancer (CRC).

METHODS

This retrospective cohort study enrolled 97 patients with primary CRC scheduled for surgery. An anchor-based approach estimated the MCID of the 6MWD, with postoperative physical recovery and EuroQol 5-dimension 5L questionnaire assessments serving as anchors. Effect size (ES) and standardized response mean (SRM) of the 6MWD were calculated to evaluate responsiveness, and the receiver operating characteristic (ROC) curve was used to estimate the MCID of the 6MWD.

RESULTS

Of the 97 patients, 72 were included in the analysis. The absolute value of ES and SRM of the 6MWD were 0.69 and 0.91, respectively. The ROC curve indicated that the optimal cut-off values for estimating the MCID of the 6MWD were -60 m (area under the curve [AUC] = 0.753 [95% CI: 0.640-0.866]) and -75 m (AUC = 0.870 [95% CI: 0.779-0.961]) at each anchor.

CONCLUSION

From before to 1 week after surgery, the responsiveness of the 6MWD was favorable, and the MCID of the 6MWD was -75 to -60 m in patients with CRC.

Long-term results of a short-term home-based pre- and postoperative exercise intervention on physical recovery after colorectal cancer surgery (PHYSSURG-C): a randomized clinical trial

AIM

The aim of this work was to assess the effect of a short-term, home-based exercise intervention before and after colorectal cancer surgery on 12-month physical recovery within a previously reported randomized control trial (RCT).

METHOD

PHYSSURG-C is an RCT in six participating hospitals in Sweden. Patients aged ≥20 years planned for elective colorectal cancer surgery were eligible. The intervention consisted of unsupervised moderate-intensity physical activity 2 weeks preoperatively and 4 weeks postoperatively. Usual care was control. The primary outcome measure in PHYSSURG-C was self-assessed physical recovery 4 weeks postoperatively. The predefined long-term follow-up outcomes included: self-assessed physical recovery 12 months postoperatively and reoperations and readmissions 91-365 days postoperatively. The statistical models were adjusted with tumour site (colon or rectum), neoadjuvant therapy (none, radiotherapy or chemo/radiotherapy) and type of surgery (open or laparoscopic).

RESULTS

A total of 616 participants were available for the 12-month follow-up. Groups were balanced at baseline regarding demographic and treatment variables. There was no effect from the intervention on self-reported physical recovery [adjusted odds ratio (OR) 0.91, p = 0.60], the risk of reoperation (OR 0.97, p = 0.91) or readmission (OR 0.88, p = 0.58).

CONCLUSION

The pre- and postoperative unsupervised moderate-intensity exercise intervention had no effect on long-term physical recovery after elective colorectal cancer surgery. There is still not enough evidence to support clinical guidelines on preoperative exercise to improve outcome after colorectal cancer surgery.

Association between preoperative modifiable lifestyle factors and mortality after cancer surgery: a population-based cohort study in South Korea

Purpose

We aimed to examine whether preoperative lifestyle factors are associated with mortality after cancer surgery.

Methods

This study used data from the National Health Insurance Service database in South Korea. We included all adult patients who underwent major cancer surgery between January 1, 2016, and December 31, 2018. Three lifestyle factors were evaluated preoperatively: smoking status, alcohol consumption, and physical activity.

Results

A total of 48,557 patients who underwent major cancer surgery were included in the final analysis. In the multivariable logistic regression modeling, current smokers showed 1.40-fold higher odds of 90-day mortality after cancer surgery (odds ratio, 1.40; 95% confidence interval, 1.14-1.71; P = 0.001) than never smokers. However, alcohol consumption and physical activity were not associated with 90-day mortality after cancer surgery. In the multivariable Cox regression modeling, current smokers showed 1.25-fold higher odds of 1-year mortality after cancer surgery (hazard ratio, 1.25; 95% confidence interval, 1.13-1.38; P < 0.001) than never smokers. However, alcohol consumption and physical activity were not associated with 1-year mortality after cancer surgery.

Conclusion

In conclusion, current smoking was associated with worse short- and long-term survival outcomes in South Korea, though preoperative alcohol consumption and physical activity levels were not associated with mortality after cancer surgery.

Preoperative Activity Level and Postoperative Pain After Pelvic Reconstructive Surgery

IMPORTANCE

Higher preoperative activity level is associated with improved postoperative outcomes, but its impact on postoperative pain after urogynecologic surgery is unknown.

OBJECTIVE

The aim of the study was to assess the relationship between preoperative activity level and postoperative pain.

STUDY DESIGN

In this prospective cohort study, we evaluated women undergoing pelvic reconstructive surgery from April 2019 through September 2021. We used the Activity Assessment Survey (AAS) to create cohorts of high (AAS = 100) and low (AAS < 100) baseline activity (BA). Our primary outcome was postoperative pain scores. Our secondary outcome was postoperative opioid use.

RESULTS

Of 132 patients, 90 (68%) were in the low BA group and 42 (32%) were in the high BA group. The groups were similar in age (mean 59 ± 12 years for high BA vs 60 ± 12 for low BA, P = 0.70), body mass index, and surgical procedures performed; however, the high BA group had lower preoperative pain scores (2 ± 6 vs 11 ± 9, P ≤ 0.01). For the primary outcome, the high BA group reported lower postoperative pain scores (16 ± 8 vs 20 ± 9, P = 0.02) and less opioid use (19 ± 32 vs 52 ± 70 morphine milliequivalents, P = 0.01) than the low BA group. However, when adjusting for age, baseline pain, hysterectomy, baseline opioid use, and Charlson Comorbidity Index, high BA did not remain associated with lower postoperative pain scores and less opioid use.

CONCLUSION

A higher preoperative activity level among patients undergoing urogynecologic surgery was not associated with lower pain scores nor decreased opioid use.

Screening for Physical Activity Levels in Non-Metastatic Breast Cancer Patients Undergoing Surgery: An Observational Study

BACKGROUND

Physical activity (PA) can play a role in lowering the risk of breast cancer (BC), but also in reducing perioperative complications and treatments related side effects, improving the quality of life and decreasing mortality in BC survivors. PA and nutritional screening are not offered to patients after cancer diagnosis as standard of care, even in high quality breast units.

METHODS

From February 2019 to March 2020, we performed a preoperative physical and nutritional screening in 504 consecutive BC patients waiting for surgery. The screening included an IPAQ questionnaire to evaluate the level of physical activity; nutritional screening with measurement of anthropometric parameters (weight, height, waist and hips circumference, BMI, and waist hip ratio) and evaluation of body composition using Bioelectrical Impedance Analysis (BIA).

RESULTS

The majority of patients in our series resulted physically inactive: clustering the IPAQ scores, 47% of patients proved to be physically inactive (MET score <700), 34% moderately active (MET score 700-2520), and only 19% physically active (MET score > 2520). In addition, approximately half of the patients (49.01%) resulted overweight or obese, and more than half (55.2%) had a percentage of fatty tissue over the recommended cut off for adult women.

CONCLUSIONS

Our data confirm that assessment of PA levels should become part of the standard preoperative evaluation of BC patients and behavioral interventions should be offered to them, in order to pre-habilitate for surgery and improve outcomes. IPAQ Questionnaire and body composition analysis could be quick and easy screening tools in order to identify which patients may need more support in being active during and after anticancer treatments.

Effect of Short-term Homebased Pre- and Postoperative Exercise on Recovery After Colorectal Cancer Surgery (PHYSSURG-C): A Randomized Clinical Trial

OBJECTIVE

To determine the effect of a short-term, unsupervised exercise intervention before and after colorectal cancer surgery on self-assessed physical recovery.

SUMMARY OF BACKGROUND DATA

Preoperative exercise interventions could help improve recovery after colorectal cancer surgery and is currently recommended.

METHODS

A randomized, parallel, open-label trial in six university or regional hospitals in Sweden. Inclusion criteria were age ≥20 years and planned elective colorectal cancer surgery. Participants were randomized to either a physical activity intervention with aerobic activity and inspiratory muscle training 2 weeks pre- and 4 weeks postoperatively or usual care. The primary outcome measure was self-assessed physical recovery 4 weeks postoperatively. Analyses were performed according to intention to treat. Outcome assessors were masked regarding the intervention while both participants and physiotherapists were informed due to the nature of the intervention.

RESULTS

Between January 22, 2015, and May 28, 2020, 761 participants were recruited and assigned to either intervention (I) (n = 379) or control (C) (n = 382). After exclusions 668 participants (I = 317, C = 351) were included in the primary analysis. There was no effect from the intervention on the primary outcome measure (adjusted odds ratio 0.84, 95% confidence interval 0.62-1.15) with 13% and 15% of participants feeling fully physically recovered in I and C, respectively. There were no reported adverse events.

CONCLUSIONS

There was no effect from a physical activity intervention before and after colorectal cancer surgery on short-term self-assessed physical recovery. The results from this study call for reconsiderations regarding current recommendations for preoperative physical activity interventions.

Association between self-assessed preoperative level of physical activity and postoperative complications - An observational cohort analysis within a randomized controlled trial (PHYSSURG-C)

INTRODUCTION

Physical activity has been suggested as a modifiable risk factor for postoperative recovery after major surgery. We aimed to further define the association between self-reported leisure time physical activity and postoperative complications and recovery on a group level.

MATERIALS AND METHODS

An observational cohort analysis was performed within a randomized controlled trial. Patients ≥20 years with colorectal cancer were eligible. Between January 2015 and May 2020, 761 participants were recruited. Leisure time physical activity was self-assessed on a four-grade scale. The primary outcome in this analysis was postoperative complications within 90 days, measured with the comprehensive complication index (CCI). Secondary outcomes were CCI for the index hospital stay, CCI 30 days postoperatively, specific types of complications, length of hospital stay, and self-assessed physical recovery. Analyses were adjusted for gender, age, study center, alcohol consumption, tumor stage, colon/rectal cancer, neoadjuvant therapy, and open or laparoscopic surgery.

RESULTS

Data on preoperative physical activity was available for 614 participants. Participants who reported some physical activity had on average a lower CCI 90 days postoperatively than sedentary participants (odds ratio 0.63, 95% CI 0.43-0.92). Similar patterns were shown for complications during hospital stay and within 30 days. There were trends towards lower risk for several types of complications, reoperations and length of hospital stay but the only difference shown was for respiratory insufficiency.

CONCLUSION

Physically active participants experienced fewer postoperative complications, which suggests the information has a potential prognostic value. The work for increasing physical activity in the general population should continue.

Postoperative Recovery Quality after General Anesthesia in Patients Undergoing Emergency Surgery

BACKGROUND: The quality of post-operative patient recovery is part of the indicators of the quality of anesthesia services. However, side effects were still found in post-operative patients, which resulted in the speed and quality of recovery (QoR) and an increase in the length of stay for patients in the hospital. AIM: This study aims to describe the quality of a patient’s recovery after general anesthesia for patients undergoing surgery in the emergency room. MATERIALS AND METHODS: This research is a descriptive study with a cross-sectional design conducted from February to July 2020. Patients numbered 52 people who are patients aged 18–59 years who are willing to fill out a questionnaire QoR-40 on the day after surgery. All data were analyzed using the statistical program SPSS. The median of the QoR-40 score will be used as a cutoff point between good and poor recovery quality. RESULTS: Fifty-two patients responded to the study with a median age of 44 years. The median QoR-40 score was 188, with most of the good category’s recovery quality (55.8%). The middle-aged group showed better QoR (68.2 vs. 31.8%), as well as the female compared to male (65 vs. 35%). Patients who underwent neurosurgery showed poor recovery 61.9 vs. 38.1%). CONCLUSION: More than half of the patients who underwent emergency surgery under general anesthesia in the emergency room of Sanglah Hospital have good recovery quality.

Recovery after breast cancer surgery following recommended pre and postoperative physical activity: (PhysSURG-B) randomized clinical trial

BACKGROUND

The effect of preoperative physical activity on recovery and complications after primary breast cancer surgery is unknown. The objective of this trial was to evaluate whether a recommendation of non-supervised physical activity improved recovery after breast cancer surgery.

METHODS

This parallel, unblinded, multicentre interventional trial randomized women in whom breast cancer surgery was planned. The intervention consisted of an individual recommendation of added aerobic physical activity (30 min/day), before and 4 weeks after surgery. The control group did not receive any advice regarding physical activity. The primary outcome was patient-reported physical recovery at 4 weeks after surgery. Secondary outcomes included mental recovery, complications, reoperations, and readmissions.

RESULTS

Between November 2016 and December 2018, 400 patients were randomized, 200 to each group. Some 370 participants (180 intervention, 190 control) remained at 4 weeks, and 368 at 90 days. There was no significant difference in favour of the intervention for the primary outcome physical recovery (risk ratio (RR) 1.03, 95 per cent c.i. 0.95 to 1.13). There was also no difference for mental recovery (RR 1.05, 0.93 to 1.17) nor in mean Comprehensive Complication Index score (4.2 (range 0-57.5) versus 4.7 (0-58.3)) between the intervention and control groups.

CONCLUSION

An intervention with recommended non-supervised physical activity before and after breast cancer surgery did not improve recovery at 4 weeks after surgery. Registration number: NCT02560662 (http://www.clinicaltrials.gov).

Preoperative exercise to improve fitness in patients undergoing complex surgery for cancer of the lung or oesophagus (PRE-HIIT): protocol for a randomized controlled trial

BACKGROUND

Patients with cancer of the lung or oesophagus, undergoing curative treatment, usually require a thoracotomy and a complex oncological resection. These surgeries carry a risk of major morbidity and mortality, and risk assessment, preoperative optimisation, and enhanced recovery after surgery (ERAS) pathways are modern approaches to optimise outcomes. Pre-operative fitness is an established predictor of postoperative outcome, accordingly, targeting pre-operative fitness through exercise prehabilitation has logical appeal. Exercise prehabilitation is challenging to implement however due to the short opportunity for intervention between diagnosis and surgery. Therefore, individually prescribed, intensive exercise training protocols which convey clinically meaningful improvements in cardiopulmonary fitness over a short period need to be investigated. This project will examine the influence of exercise prehabilitation on physiological outcomes and postoperative recovery and, through evaluation of health economics, the impact of the programme on hospital costs.

METHODS

The PRE-HIIT Randomised Controlled Trial (RCT) will compare a 2-week high intensity interval training (HIIT) programme to standard preoperative care in a cohort of thoracic and oesophageal patients who are > 2-weeks pre-surgery. A total of 78 participants will be recruited (39 per study arm). The primary outcome is cardiorespiratory fitness. Secondary outcomes include, measures of pulmonary and physical and quality of life. Outcomes will be measured at baseline (T0), and post-intervention (T1). Post-operative morbidity will also be captured. The impact of PRE-HIIT on well-being will be examined qualitatively with focus groups/interviews post-intervention (T1). Participant's experience of preparation for surgery on the PRE-HIIT trial will also be explored. The healthcare costs associated with the PRE-HITT programme, in particular acute hospital costs, will also be examined.

DISCUSSION

The overall aim of this RCT is to examine the effect of tailored, individually prescribed high intensity interval training aerobic exercise on pre-operative fitness and postoperative recovery for patients undergoing complex surgical resections, and the impact on use of health services.

Effects of a home-based exercise program on the insulin-like growth factor axis in patients operated for colorectal cancer in Sweden: Results from the randomised controlled trial PHYSSURG-C

OBJECTIVES

We report results from a subgroup within the ongoing PHYSSURG-C trial with the aim to examine effects of exercise on IGF-1 and IGFBP-3 in patients undergoing colorectal cancer surgery.

DESIGN

Randomised controlled trial.

SETTING

A Swedish university hospital.

PARTICIPANTS

Between 2015 and 2016, 217 patients were enrolled (I = 106, C = 111), with 122 patients that had given blood samples at baseline and at least at one follow-up (I = 51, C = 71). Patients 20 year or older with colorectal cancer were eligible. Exclusion criteria were emergency surgery, local surgery, language problems or inability to perform intervention.

INTERVENTIONS

Patients were computer-randomised to either a daily home-based aerobic exercise intervention (I), or to usual care (C). The intervention lasted two weeks before surgery and four weeks after discharge from hospital and consisted of medium-intensity aerobic exercise and inspiratory muscle training. Circulating concentrations of IGF-1 and IGFBP-3 were determined by blinded personnel at baseline, time of surgery and 4-6 weeks postoperatively.

PRIMARY AND SECONDARY OUTCOME MEASURES

The outcome of this subpopulation report was change in IGF-1/IGFBP-3 ratio, IGF-1 and IGFBP-3 concentrations from baseline to surgery, and 4-6 weeks postoperatively.

RESULTS

The IGF-1/IGFBP-3 ratio increased from baseline to surgery by 11% in I and 8% in C with no difference between groups (I vs. C: 1.04, 95%CI: 0.97-1.11; p = 1.000). Postoperative change was 5% in I and 3% in C with no difference between groups (I vs. C:1.03, 95%CI: 0.96-1.10; p = 1.000). Results concerning IGF-1 and IGFBP-3 also showed statistically significant dynamics over time with no difference between groups. No adverse events were reported.

CONCLUSIONS

The home-based exercise program in our trial did not have any effect on IGF-1, or IGFBP-3.

Feasibility of Telephone Follow-Up after Critical Care Discharge

Background: Critical care has evolved from a primary focus on short-term survival, with greater attention being placed on longer-term health care outcomes. It is not known how best to implement follow-up after critical care discharge. Study aims were to (1) assess the uptake and feasibility of telephone follow-up after a critical care stay and (2) profile overall physical status and recovery during the sub-acute recovery period using a telephone follow-up assessment. Methods: Adults who had been admitted to critical care units of St. James’s Hospital, Dublin, for >72 h were followed up by telephone 3–9 months post discharge from critical care. The telephone assessment consisted of a battery of questionnaires (including the SF-36 questionnaire and the Clinical Frailty Scale) and examined quality of life, frailty, employment status, and feasibility of telephone follow-up. Results: Sixty five percent (n = 91) of eligible participants were reachable by telephone. Of these, 80% (n = 73) participated in data collection. Only 7% (n = 5) expressed a preference for face-to-face hospital-based follow-up as opposed to telephone follow-up. For the SF-36, scores were lower in a number of physical health domains as compared to population norms. Frailty increased in 43.2% (n = 32) of participants compared to pre-admission status. Two-thirds (n = 48) reported being >70% physically recovered. Conclusion: Results showed that telephone follow-up is a useful contact method for a typically hard-to-reach population. Deficits in physical health and frailty were noted in the sub-acute period after discharge from critical care.

Low Preoperative Mental and Physical Health is Associated with Poorer Postoperative Recovery in Patients Undergoing Day Surgery: A Secondary Analysis from a Randomized Controlled Study

BACKGROUND

Day surgical procedures are increasing both in Sweden and internationally. Day surgery patients prepare for and handle their recovery on their own at home. The aim of this study was to investigate patients' preoperative mental and physical health and its association with the quality of their recovery after day surgery.

METHOD

This was a secondary analysis of a randomized controlled trial. Data were collected at four-day surgery units in Sweden. Health-related quality of life was measured using the Short Form 36 (SF-36) Health Survey, and postoperative recovery was assessed using the Swedish web version of the Quality of Recovery (SwQoR) scale.

RESULT

This study included 756-day surgery patients. A low, compared with a high, preoperative mental component score was associated with poorer recovery as shown by responses to 21/24 and 22/24 SwQoR items, respectively, on postoperative days (PODs) 7 and 14. A low compared with a high preoperative physical component score was associated with poorer recovery in 18/24 SwQoR items on POD 7 and 13/24 on POD 14.

CONCLUSION

A clear message from this study is for surgeons, anaesthetists and nurses to consider the fact that postoperative recovery largely depends on patients' preoperative mental and psychical status. A serious attempt must be made, as a part of the routine preoperative assessment, to assess and document not only the physical but also the mental status of patients undergoing anaesthesia and surgery.

Preliminary evidence for physical activity following pelvic exenteration: a pilot longitudinal cohort study

Background

The physical activity (PA) level of patients undergoing major cancer surgery remains unclear. This pilot study aimed to: (i) Compare preoperative PA level between patients undergoing major cancer surgery and the general population; (ii) describe PA trajectories following major cancer surgery; (iii) Compare objective versus subjective PA measures in patients undergoing major cancer surgery; and (iv) Investigate the association between preoperative PA level and postoperative outcomes.

Methods

Patients undergoing pelvic exenteration between September/2016 and September/2017 were included and followed at preoperative, 6-weeks and 6-months postoperative. PA was measured using the International Physical Activity Questionnaire Short-Form and McRoberts activity monitor. Analyses were performed using SPSS.

Results

This pilot study included 16 patients. When compared to the general population, patients undergoing major cancer surgery presented a reduced preoperative PA level. PA levels decreased at 6 weeks but returned to preoperative levels at 6 months postoperative. Objective and subjective measures of PA were comparable, with some variables presenting strong correlations. A higher preoperative level PA was associated with an absence of postoperative complications and better quality of life outcomes.

Conclusions

Patients undergoing major cancer surgery demonstrated lower PA levels when compared to the general population. PA trajectories decreased at 6 weeks postoperative, returning to preoperative levels within 6-months. In this cohort, it seems that higher preoperative PA level may improve postoperative surgical outcomes; however, this preliminary evidence should be confirmed in a larger cohort.

Self-assessed preoperative level of habitual physical activity predicted postoperative complications after colorectal cancer surgery: A prospective observational cohort study

INTRODUCTION

There is a growing interest in physical activity in relation to recovery after surgery. One important aspect of measuring recovery after surgical procedures is postoperative complications. The aim of this study was to determine if there is an association between the preoperative level of habitual physical activity and postoperative complications in patients undergoing elective surgery for colorectal cancer.

MATERIALS AND METHODS

115 patients scheduled for elective surgery due to colorectal cancer between February 2014 and September 2015 answered a questionnaire regarding physical activity and other baseline variables. Physical activity was assessed using the Saltin-Grimby physical activity level scale. Complications within 30 days after surgery were classified according to Clavien-Dindo, and the Comprehensive Complications Index (CCI) was calculated. Primary outcome was difference in CCI and key secondary outcome was risk for CCI ≥20.

RESULTS

Physically inactive individuals had a CCI that was 12 points higher than individuals with light activity (p = 0.002) and 17 points higher than regularly active individuals (p = 0.0004). Inactive individuals had a relative risk for a CCI ≥20 that was 65% higher than for individuals reporting light activity (95% confidence interval (CI) for relative risk (RR) = 1.1-2.5) and 338% higher than for regularly active individuals (95% CI for RR = 2.1-9.4).

CONCLUSION

Self-assessed level of habitual physical activity before colorectal cancer surgery was associated with fewer postoperative complications measured with CCI, in a dose-response relationship.

Measurement of patient-reported outcomes after laparoscopic cholecystectomy: a systematic review

BACKGROUND

Patient-reported outcome (PRO) measures (PROMs) are increasingly used as endpoints in surgical trials. PROs need to be consistently measured and reported to accurately evaluate surgical care. Laparoscopic cholecystectomy (LC) is a commonly performed procedure which may be evaluated by PROs. We aimed to evaluate the frequency and consistency of PRO measurement and reporting after LC.

METHODS

MEDLINE, EMBASE, and the Cochrane Central Register of Controlled Trials were searched for prospective studies reporting PROs of LC, between 2013 and 2016. Data on the measurement and reporting of PROs were extracted.

RESULTS

A total of 281 studies were evaluated. Forty-five unique multi-item questionnaires were identified, most of which were used in single studies (n = 35). One hundred and ten unique rating scales were used to assess 358 PROs. The visual analogue scale was used to assess 24 different PROs, 17 of which were only reported in single studies. Details about the type of rating scale used were not given for 72 scales. Three hundred and twenty-three PROs were reported in 162 studies without details given about the scale or questionnaire used to evaluate them.

CONCLUSIONS

Considerable variation was identified in the choice of PROs reported after LC, and in how they were measured. PRO measurement for LC is focused on short-term outcomes, such as post-operative pain, rather than longer-term outcomes. Consideration should be given towards the development of a core outcome set for LC which incorporates PROs.

The effect of pre- and post-operative physical activity on recovery after colorectal cancer surgery (PHYSSURG-C): study protocol for a randomised controlled trial

Background

Surgery for colorectal cancer is associated with a high risk of post-operative adverse events, re-operations and a prolonged post-operative recovery. Previously, the effect of prehabilitation (pre-operative physical activity) has been studied for different types of surgery, including colorectal surgery. However, the trials on colorectal surgery have been of limited methodological quality and size. The aim of this trial is to compare the effect of a combined pre- and post-operative intervention of moderate aerobic physical activity and inspiratory muscle training (IMT) with standard care on post-operative recovery after surgery for colorectal cancer.

Methods/design

We are conducting a randomised, controlled, parallel-group, open-label, multi-centre trial with physical recovery within 4 weeks after cancer surgery as the primary endpoint. Some 640 patients planned for surgery for colorectal cancer will be enrolled. The intervention consists of pre- and post-operative physical activity with increased daily aerobic activity of moderate intensity as well as IMT. In the control group, patients will be advised to continue their normal daily exercise routine. The primary outcome is patient-reported physical recovery 4 weeks post-operatively. Secondary outcomes are length of sick leave, complication rate and severity, length of hospital stay, re-admittances, re-operations, post-operative mental recovery, quality of life and mortality, as well as changes in insulin-like growth factor 1 and insulin-like growth factor-binding protein 3, perception of pain and a health economic analysis.

Discussion

An increase in moderate-intensity aerobic physical activity is a safe, cheap and feasible intervention that would be possible to implement in standard care for patients with colorectal cancer. If shown to be effective, this lifestyle intervention could be a clinical parallel to pre-operative smoke cessation that has already been implemented with good clinical results.

Measurement properties of the Human Activity Profile questionnaire in hospitalized patients

OBJECTIVE

To test the measurement properties (reproducibility, internal consistency, ceiling and floor effects, and construct validity) of the Human Activity Profile (HAP) questionnaire in hospitalized patients.

METHODS

This measurement properties study recruited one-hundred patients hospitalized for less than 48h for clinical or surgical reasons. The HAP was administered at baseline and after 48h in a test-retest design). The International Physical Activity Questionnaire (IPAQ-6) was also administered at baseline, aiming to assess the construct validity. We tested the following measurement properties: reproducibility (reliability assessed by type 2,1 intraclass correlation coefficient (ICC2,1)); agreement by the standard error of measurement (SEM) and by the minimum detectable change with 90% confidence (MDC90), internal consistency by Cronbach's alpha, construct validity using a chi-square test, and ceiling and floor effects by calculating the proportion of patients who achieved the minimum or maximum scores.

RESULTS

Reliability was excellent with an ICC of 0.99 (95% CI=0.98-0.99). SEM was 1.44 points (1.5% of the total score), the MDD90 was 3.34 points (3.5% of the total score) and the Cronbach's alpha was 0.93 (alpha if item deleted ranging from 0.94 to 0.94). An association was observed between patients classified by HAP and by IPAQ-6 (χ2=3.38; p=0.18). Ceiling or floor effects were not observed.

CONCLUSION

The HAP shows adequate measurement properties for the assessment of the physical activity/inactivity level in hospitalized patients.

Is preoperative physical activity related to post-surgery recovery?-a cohort study of colorectal cancer patients

INTRODUCTION

An increasing interest is seen in the role of preoperative physical activity (PA) in enhancing postoperative recovery. The short-term effect of preoperative PA on recovery after colorectal cancer is unknown. The aim of this study was to evaluate the association of the preoperative level of PA with postoperative recovery after surgery due to colorectal cancer disease.

METHODS

This is a prospective observational cohort study, with 115 patients scheduled to undergo elective colorectal surgery. The self-reported level of preoperative PA was compared to measures of recovery.

RESULTS

Regular self-reported preoperative PA was associated with a higher chance of feeling highly physically recovered 3 weeks after surgery (relative chance 3.3, p = 0.038), compared to physical inactivity. No statistically significant associations were seen with length of hospital stay, self-assessed mental recovery, re-admittances or with re-operations.

DISCUSSION

In clinical practice, evaluating the patients' level of PA is feasible and may potentially be used as a prognostic tool for patients undergoing colorectal cancer surgery. Given the study design, the results from this study cannot prove causality.

CONCLUSION

The present study found that the preoperative level of PA was associated with a faster self-assessed physical recovery after colorectal cancer surgery. PA did not show any associations with the primary outcome measure length of hospital stay or any of the other secondary outcome measures. Assessment of PA level preoperatively could be used for prognostic reasons. If systematic preoperative/postoperative physical training will enhance recovery, this remains to be studied in a randomized controlled study.

HIGHLIGHTS

We examined preoperative physical activity and the recovery after colorectal cancer surgery. Physically active individuals had faster self-assessed physical recovery. Assessment of preoperative physical activity may provide prognostic clinical information.
