Measuring illness beliefs in patients with lower extremity injuries: reliability and validity of the Dutch version of the Somatic Pre-Occupation and Coping questionnaire (SPOC-NL)

Cognitive Behavioural Therapy to Optimize Post-Operative Recovery (COPE): a randomized controlled feasibility trial in extremity fracture patients

BACKGROUND

Outcomes following surgery to operatively manage extremity fractures are variable, and up to two-thirds of patients report chronic post-surgical pain. Preliminary evidence suggests that psychotherapy directed at improving coping skills and reducing somatic vigilance may improve outcomes among fracture patients. The objective of this pilot study was to test the feasibility and acceptability of a randomized controlled trial comparing an online cognitive behavioural therapy (CBT) program versus usual care in patients with an operatively managed open or closed extremity fracture.

METHODS

We conducted a single-centre internal pilot study over a 10-month period in patients with at least one operatively managed open or closed fracture of the appendicular skeleton. Participants were randomized to an online CBT program or usual care and followed for 12 months. The goals of our pilot study were to determine an acceptable rate of recruitment, the degree to which participants randomized to CBT were compliant with treatment, the site investigator's ability to adhere to study protocol and data collection procedures, and our ability to achieve high follow-up rates. Feasibility criteria were evaluated using a graded "traffic light" approach, in which "green light" indicates moving forward with the definitive trial, "yellow light" indicates proceeding with modifications to the protocol and trial procedures, and "red light" indicates a definitive trial is not feasible without significant protocol and trial procedure modifications.

RESULTS

We enrolled 94 participants over 10 months, which resulted in a "yellow light" for recruitment. Participant compliance with completion of the online CBT program received a "yellow light", with 60% of participants who were randomized to CBT completing all seven modules. However, 40% of participants in the CBT-arm withdrew from the program, resulting in a "red light". Adherence with the study protocol activities at baseline was relatively high (88%) which resulted in a "yellow light". Follow-up was 85% (80 of 94) at 12 months, resulting in a "yellow light".

CONCLUSIONS

These results suggest feasibility of a definitive, multi-centre trial to compare CBT versus usual care in the management of persistent post-operative pain in fracture patients despite the pilot phase identifying some challenges with enrollment timelines, compliance with the CBT program, and participant follow-up. For the definitive trial, we will expand participant recruitment to additional centres and implement strategies to optimize participant engagement and compliance with the CBT program and follow-up.

In-person cognitive behavioural therapy vs. usual care after surgical management of extremity fractures: an unsuccessful feasibility trial

BACKGROUND

Extremity fractures are common, and most are managed operatively; however, despite successful reduction, up to half of patients report persistent post-surgical pain. Furthermore, psychological factors such as stress, distress, anxiety, depression, catastrophizing, and fear-avoidance behaviors have been associated with the development of chronic pain. The purpose of this pilot study was to examine the feasibility of a randomized controlled trial to determine the effect of in-person cognitive behavioral therapy (CBT) vs. usual care on persistent post-surgical pain among patients with a surgically managed extremity fracture.

METHODS

Eligible patients were randomized to either in-person CBT or usual care. We used four criteria to judge the composite measure of feasibility: 1) successful implementation of CBT at each clinical site, 2) 40 patients recruited within 6 months, 3) treatment compliance in a minimum 36 of 40 participants (90%), and 4) 32 of 40 participants (80%) achieving follow-up at one year. The primary clinical outcome was persistent post-surgical pain at one year after surgery.

RESULTS

Only two of the four participating sites were able to implement the CBT regimen due to difficulties with identifying certified therapists who had the capacity to accommodate additional patients into their schedule within the required timeframe (i.e., 8 weeks of their fracture). Given the challenges associated with CBT implementation, only one site was able to actively recruit patients. This site screened 86 patients and enrolled 3 patients (3.5%) over a period of three months. Participants were unable to comply with the in-person CBT, with no participants attending an in-person CBT session. Follow-up at one year could not be assessed as the pilot study was stopped early, three months into the study, due to failure to achieve the other three feasibility criteria.

CONCLUSION

Our pilot trial failed to demonstrate the feasibility of a trial of in-person CBT versus usual care to prevent persistent pain after surgical repair of traumatic long-bone fractures and re-enforces the importance of establishing feasibility before embarking on definitive trials. Protocol modifications to address the identified barriers include the delivery of our intervention as a therapist-guided, remote CBT program.

I'll be back - Predictive validity of adults' expectations for recovery after fractures - A longitudinal observational study

PURPOSE

Recovery after fractures due to accidents relates to all aspects of the biopsychosocial model. Therefore, it is difficult for the patients to foresee the consequences of the fractures. This study aimed to examine 1) patients' expectations regarding the impact of the injury on everyday life, 2) predictive validity of their expectations after six months, and 3) factors that predict a return to work.

PATIENTS AND METHODS

Patients were 18-64 years old and hospitalized with simple or compound/multiple fractures due to an accident. During admission, structured interviews were conducted with a questionnaire covering working conditions, expectations regarding recovery, sports, economy, family, household, and return to work. Additionally, mental and physical status were covered with Short Musculoskeletal Function Assessment questionnaire (SMFA) and Short Form 36, and working conditions were uncovered too. After six months, telephonic interviews were conducted with the 164 available patients to elucidate the impact of the fractures on everyday life, their health status, and sick leave. Likelihood ratios, post-test probabilities, and logistic regression analysis were performed to establish if patients' expectations predicted recovery, economy, sports, family, household, and return to work.

RESULTS

Few patients' baseline expectations about everyday life were met. The likelihood ratios were small, and the post-test probabilities for expectations consistent with outcomes were between 18% and 68%, with recovery as the lowest and participation in sports as the highest. In the multivariate analysis, patients' expectations did not predict short-term (less than two months) or long-term sick leave (more than three months). Self-rated health and the bother index of SMFA were significant short-term and long-term predictors for sick leave. Additionally, vitality, pain, and decision latitude at work predicted sick leave of less than two months.

CONCLUSION

A few days after the accident, patients' expectations about everyday life are not associated with outcomes six months later. Likelihood ratios indicate difficulties for the patients in predicting fractures' consequences on various aspects of everyday life. Return to work was associated with self-rated health and the bother index of SMFA. Future research should examine if fracture patients can benefit from comprehensive, individual counseling during admission to set appropriate expectations.

Cognitive Behavioural Therapy to Optimize Post-Operative Fracture Recovery (COPE): protocol for a randomized controlled trial

IMPORTANCE

Chronic, non-cancer pain affects approximately 20-30% of the population in North America, Europe, and Australia, with surgery and trauma frequently cited as inciting events. Prospective studies of fracture patients have demonstrated an association between somatic pre-occupation, poor coping, and low recovery expectations following surgery with persistent pain, functional limitations, and lower rates of return to work. Psychological interventions, such as cognitive behavioural therapy (CBT), that are designed to modify unhelpful beliefs and behaviours have the potential to reduce persistent post-surgical pain and its associated effects among trauma patients.

OBJECTIVE

To determine whether online CBT, versus usual care, reduces the prevalence of moderate to severe persistent post-surgical pain among participants with an open or closed fracture of the appendicular skeleton.

DESIGN, SETTING, AND PARTICIPANTS

The Cognitive Behavioural Therapy to Optimize Post-Operative Fracture Recovery (COPE) protocol will be followed to conduct a multi-centre randomized controlled trial. Participants undergoing surgical repair of a long bone fracture will be randomized to receive either (1) online CBT modules with asynchronous therapist feedback or (2) usual care. The primary outcome will be the prevalence of moderate to severe persistent post-surgical pain over 12 months post-fracture. Secondary outcomes include the Short Form-36 Physical and Mental Component Summary scores, return to function, pain severity and pain interference over 12 months post-fracture, and the proportion of patients prescribed opioid class medications (and average dose) at 6 and 12 months post-fracture. The COPE trial will enroll 1000 participants with open and closed fractures of the appendicular skeleton from approximately 10 hospitals in North America.

DISCUSSION

If CBT is effective in improving outcomes among patients with traumatic fractures, our findings will promote a new model of care that incorporates psychological barriers to recovery.

Smoking, Obesity, and Disability Benefits or Litigation Are Not Associated with Clinically Important Reductions in Physical Functioning After Intramedullary Nailing of Tibial Shaft Fractures: A Retrospective Cohort Study

BACKGROUND

Forty percent of long bone fractures involve the tibia. These fractures are associated with prolonged recovery and may adversely affect patients' long-term physical functioning; however, there is limited evidence to inform what factors influence functional recovery in this patient population.

QUESTION/PURPOSE

In a secondary analysis of a previous randomized trial, we asked: What fracture-related, demographic, social, or rehabilitative factors were associated with physical function 1 year after reamed intramedullary nailing of open or closed tibial shaft fractures?

METHODS

This is a secondary (retrospective) analysis of a prior randomized trial (Trial to Re-evaluate Ultrasound in the Treatment of Tibial Fractures; TRUST trial). In the TRUST trial, 501 patients with unilateral open or closed tibial shaft fractures were randomized to self-administer daily low-intensity pulsed ultrasound or use a sham device, of which 15% (73 of 501) were not followed for 1 year due to early study termination as a result of futility (no difference between active and sham interventions). Of the remaining patients, 70% (299 of 428) provided full data. All fractures were fixed using reamed (298 of 299) or unreamed (1 of 299) intramedullary nailing. Thus, we excluded the sole fracture fixed using unreamed intramedullary nailing. The co-primary study outcomes of the TRUST trial were time to radiographic healing and SF-36 physical component summary (SF-36 PCS) scores at 1-year. SF-36 PCS scores range from 0 to 100, with higher scores being better, and the minimum clinically important difference (MCID) is 5 points. In this secondary analysis, based on clinical and biological rationale, we selected factors that may be associated with physical functioning as measured by SF-36 PCS scores. All selected factors were inserted simultaneously into a multivariate linear regression analysis.

RESULTS

After adjusting for potentially confounding factors, such as age, gender, and injury severity, we found that no factor showed an association that exceeded the MCID for physical functioning 1 year after intramedullary nailing for tibial shaft fractures. The independent variables associated with lower physical functioning were current smoking status (mean difference -3.0 [95% confidence interval -5 to -0.5]; p = 0.02), BMI > 30 kg/m2 (mean difference -3.0 [95% CI -5.0 to -0.3]; p = 0.03), and receipt of disability benefits or involvement in litigation, or plans to be (mean difference -3.0 [95% CI -5.0 to -1]; p = 0.007). Patients who were employed (mean difference 4.6 [95% CI 2.0 to 7]; p < 0.001) and those who were advised by their surgeon to partially or fully bear weight postoperatively (mean difference 2.0 [95% CI 0.1 to 4.0]; p = 0.04) were associated with higher physical functioning. Age, gender, fracture severity, and receipt of early physical therapy were not associated with physical functioning at 1-year following surgical fixation.

CONCLUSION

Among patients with tibial fractures, none of the factors we analyzed, including smoking status, receipt of disability benefits or involvement in litigation, or BMI, showed an association with physical functioning that exceeded the MCID.

Using the STTGMA Risk Stratification Tool to Predict Complications, Additional Operations, and Functional Outcomes After Ankle Fracture

OBJECTIVES

To determine the usefulness of a validated trauma triage score to stratify postdischarge complications, secondary procedures, and functional outcomes after ankle fracture.

DESIGN

Retrospective cohort.

SETTING

Level 1 trauma center.

PATIENTS

Four hundred fifteen patients 55 years of age and older with 431 ankle fractures.

INTERVENTION

Closed or open reduction.

MAIN OUTCOME MEASUREMENTS

Score for Trauma Triage in Geriatric and Middle-Aged Patients (STTGMA), postdischarge complications, secondary operations, Foot Function Index (FFI, n = 167), and Short Musculoskeletal Function Assessment (SMFA, n = 165).

RESULTS

Mean age was 66 years, 38% were men, and 68% of fractures were secondary to ground-level falls. Forty patients (9.6%) required an additional procedure, with implant removal most common (n = 21, 5.1%), and 102 (25%) experienced a postdischarge complication. On multiple linear regression, STTGMA was not a significant independent predictor of complications or secondary procedures. Patients completed FFI and SMFA surveys a median of 62 months (5.2 years) after injury. On the FFI, low-risk STTGMA stratification was an independent predictor of worse functional outcomes. Similarly, low-risk stratification was a predictor of worse scores on the SMFA dysfunction and daily activity subcategories (both B > 10, P < 0.05).

CONCLUSIONS

Low-risk STTGMA stratification predicted worse long-term function. The STTGMA tool was not able to meaningfully stratify risk of postdischarge complications and secondary procedures after ankle fracture.

Effectiveness and cost-effectiveness of the Transmural Trauma Care Model investigated in a multicenter trial with a controlled before-and-after design: A study protocol

OBJECTIVE

The rehabilitation of trauma patients in primary care is challenging, and there are no guidelines for optimal treatment. Also, the organization of care is not well-structured. The Transmural Trauma Care Model (TTCM) has been developed in the Netherlands, aiming to improve patient outcomes by optimizing the organization and the quality of the rehabilitation process in primary care. A recent feasibility study showed that implementation of the TTCM at a Dutch Level 1 trauma center was feasible, patient outcomes were improved, and costs were reduced. This study aims to assess the effectiveness and cost-effectiveness of the TTCM compared to the usual care in a multicenter trial.

METHODS

A multicenter trial with a controlled before-and-after design will be performed at 10 hospitals in the Netherlands. First, participating hospitals will include 322 patients in the control group, receiving usual care as provided in these specific hospitals. Subsequently, the TTCM will be implemented in all participating hospitals, and hospitals will include an additional 322 patients in the intervention group. The TTCM consists of a multidisciplinary team at the outpatient clinic (trauma surgeon and hospital-based physical therapist), an educated and trained network of primary care trauma physical therapists, and structural communication between them. Co-primary outcomes will investigate generic and disease-specific, health-related quality of life. Secondary outcomes will include pain, patient satisfaction, perceived recovery, and patient-reported physical functioning. For the economic evaluation, societal and healthcare costs will be measured. Measurements will take place at baseline and after 6 weeks, 3, 6, and 9 months. Analyses will be based on the intention-to-treat principle. Missing data will be handled using longitudinal data analyses in the effect analyses and by multivariate imputation in the economic evaluation.

CONCLUSION

This trial with a controlled before-and-after design will give insight into the effectiveness and cost-effectiveness of the TTCM in a multicenter trial.

Quickscan assesses risk factors of long-term sickness absence: A cross-sectional (factorial) construct validation study

Objectives

The number of sick-listed employees has increased dramatically worldwide. Therefore, many countries aim to stimulate early and sustainable return to work opportunities to obtain better health outcomes and lower costs for disability pensions. To effectively orientate resources to patients with a high risk of not resuming work spontaneously, it is necessary to screen patients early in their sickness absence process. In this study, we validate “Quickscan”, a new instrument to assess return-to-work needs and to predict risks of long-term sick leave.

Methods

As part of the Quickscan validation process, we tested and compared the reliability and construct validity of the questionnaire in two different populations. First, we conducted a cross-sectional study in which the screening instrument was sent to sick-listed individuals in healthcare insurance. In a second cross-sectional study, sick-listed workers who consulted the occupational health physician for return-to-work assessment were asked to fill out the questionnaire. We compared both samples for descriptive statistics: frequencies, means and standard deviations. Reliability of the scales was calculated using Cronbach’s alpha. Confirmatory factor analysis was performed to evaluate the construct (factorial) validity of the studied scales using software package AMOS 24.

Results

The screening tool was shown to be an instrument with reliable scales (except for the perfectionism and health perception patient scale) in both populations. The construct validity was satisfactory: we found that the hypothesized measurement models with the theoretical factors fitted the data well in both populations. In the first sample, the model improved for scales concerning stressful life events and showed worse fit for person-related factors. Work-related factors and functioning factors both showed similar fit indices across samples. We found small differences in descriptive statistics, which we could explain by the differences in characteristics of both populations.

Conclusions

We can conclude that the instrument has considerable potential to function as a screening tool for disability management and follow-up of sick-leave, provided that some adaptations and validation tests are executed.

Patient coping and expectations about recovery predict the development of chronic post-surgical pain after traumatic tibial fracture repair

BACKGROUND

The association of patient expectations about recovery with the development of chronic post-surgical pain (CPSP) is uncertain.

METHODS

Three hundred and fifty-nine patients enrolled in the SPRINT trial completed the Somatic Preoccupation and Coping (SPOC) questionnaire six weeks after a traumatic tibial fracture repair. The SPOC questionnaire measures patients' somatic complaints, coping, and optimism for recovery. Using adjusted models, we explored the association of SPOC scores with ≥ mild CPSP and ≥ moderate pain interference with activity at one yr after surgery.

RESULTS

Of 267 tibial fracture patients with data available for analysis, 147 (55.1%) reported CPSP at one yr. The incidence of CPSP was 37.6% among those with low (≤40) SPOC scores, 54.1% among those with intermediate (41-80) scores, and 81.7% among those with high (>80) scores. Addition of SPOC scores to an adjusted regression model to predict CPSP improved the c-statistic from 0.61 (95% CI 0.55-0.68) to 0.70 (95% CI 0.64-0.76, P=0.005 for the difference) and found the greatest risk was associated with high SPOC scores (OR 6.56, 95% CI 2.90-14.81). Similarly, an adjusted regression model to predict pain interference with function at one yr (c-statistic 0.77, 95% CI 0.71-0.83) found the greatest risk for those with high SPOC scores (OR 10.10, 95% CI 4.26-23.96).

CONCLUSIONS

Patient's coping and expectations of recovery, as measured by the SPOC questionnaire, is an independent predictor of CPSP and pain interference one yr after traumatic tibial fracture. Future studies should explore whether these beliefs can be modified, and if doing so improves prognosis.

Perioperative psychotherapy for persistent post-surgical pain and physical impairment: a meta-analysis of randomised trials

BACKGROUND

Persistent post-surgical pain affects 10-80% of individuals after common operations, and is more common among patients with psychological factors such as depression, anxiety, or catastrophising.

METHODS

We conducted a systematic review and meta-analysis of randomised, controlled trials to evaluate the efficacy of perioperative psychotherapy for persistent post-surgical pain and physical impairment. Paired independent reviewers identified studies, extracted data, and assessed risk of bias. The Grading of Recommendations, Assessment, Development and Evaluation system was used to assess the quality of evidence.

RESULTS

Our search of five electronic databases, up to September 1, 2016, found 15 trials (2220 patients) that were eligible for review. For both persistent post-surgical pain and physical impairment, perioperative education was ineffective, while active psychotherapy suggested a benefit (test of interaction P=0.01 for both outcomes). Moderate quality evidence showed that active perioperative psychotherapy (cognitive-behaviour therapy, relaxation therapy, or both) significantly reduced persistent post-surgical pain [weighted mean difference (WMD) -1.06 cm on a 10 cm visual analogue scale for pain, 95% confidence interval (CI) -1.56 to -0.55 cm; risk difference (RD) for achieving no more than mild pain (≤3 cm) 14%, 95% CI 8-21%] and physical impairment [WMD -9.87% on the 0-100% Oswestry Disability Index, 95% CI -13.42 to -6.32%, RD for achieving no more than mild disability (≤20%) 21%, 95% CI 13-29%].

CONCLUSIONS

Perioperative cognitive behavioural therapy and relaxation therapy are effective for reducing persistent pain and physical impairment after surgery. Future studies should explore targeted psychotherapy for surgical patients at higher risk for poor outcome.
