Item reduction of the patient-rated wrist evaluation using decision tree modelling
© 2019 The Author(s). Published by Informa UK Limited, trading as Taylor & Francis Group. Background: The aim of this study is to assess the viability of a decision tree version of an often used questionnaire to measure wrist pain and disability, the Patient Rated Wrist Evaluation. Methods: Patient Rated Wrist Evaluation scores were collected from a cohort of 10394 patients who are part of a routine outcome measurement system. A decision tree version of the Patient Rated Wrist Evaluation (PRWE) was created. The intraclass correlation was used to evaluate the inter-version reliability between the original PRWE and the decision tree version. Results: The decision tree reduced the number of questions from 5 to 3 for the pain subscale, and from 10 to 3 for the disability subscale. The intraclass correlation between the original PRWE and the decision tree version was 0.97. The mean difference between the Patient Rated Wrist Evaluation and the decision tree Patient Rated Wrist Evaluation total sumscore was 0.35 (95% CI −9.92–10.62). Conclusions: We found that the decision tree was successful at reducing the items of the Patient Rated Wrist Evaluation from fifteen to only six questions with very high similarity to the scores of the full questionnaire.Implications for rehabilitation The Patient Rated Wrist Evaluation can reliably be used with 6 instead of 15 questions. Decision trees are useful statistical tools to shorten lengthy questionnaires, especially when large amounts of data are available. Having a shortened Patient Rated Wrist Evaluation saves patients and clinicians time in answering this specific questionnaire
Prevalence of post-traumatic neuropathic pain after digital nerve repair and finger amputation
Introduction: Post-traumatic neuropathic pain is a major factor affecting the quality of life after finger trauma and is reported with considerable variance in the literature. This can partially be attributed to the different methods of determining neuropathic pain. The Douleur Neuropathique 4 (DN4) has been validated to be a reliable and non-invasive tool to assess the presence of neuropathic pain. This study investigated the prevalence of neuropathic pain after finger amputation or digital nerve repair using the DN4 questionnaire. Methods: Patients with finger amputation or digital nerve repair were identified between 2011 and 2018 at our institution. After a minimal follow-up of 12 months, the short form DN4 (S-DN4) was used to assess neuropathic pain. Results: A total of 120 patients were included: 50 patients with 91 digital amputations and 70 patients with 87 fingers with digital nerve repair. In the amputation group, 32% of the patients had pain, and 18% had neuropathic pain. In the digital nerve repair group, 38% of the patients had pain, and 14% had neuropathic pain. Secondly, of patient-, trauma-, and treatment-specific factors, only the time between trauma and surgery had a significant negative influence on the prevalence of neuropathic pain in patients with digital nerve repair. Conclusion: This study shows that persistent pain and neuropathic pain are common after finger trauma with nerve damage. One of the significant prognostic factors in developing neuropathic pain is treatment delay between trauma and time of digital nerve repair, which is of major clinical relevance for surgical planning of these injuries.</p
Preoperative Indicators of the Effectiveness of Surgical Release in Patients with de Quervain Disease:A Prospective Cohort Study
Background: A significant proportion of patients report persistent pain after surgical release for de Quervain disease (DQ). This study aimed to investigate the effectiveness of a surgical release for DQ and to identify the preoperative factors associated with pain after a surgical release for DQ. Methods: This prospective cohort study included 707 patients who underwent surgical release and completed a visual analogue scale questionnaire (VAS; range 0 to 100). We used a paired t test to analyze the effectiveness of the surgical release on pain at 3 months postoperatively compared with the preoperative measure. A hierarchical multivariable linear regression model was created to investigate the contribution of patient-related and disease-related characteristics to postoperative pain. Results: All VAS domains showed improvement after surgical release. On average, the mean VAS pain decreased by 44 points (95% CI, 42, 46). Smoking (B = 6.37; P < 0.01), younger age (B = -0.35; P < 0.01), longer duration of complaints (B = 0.13; P < 0.01), concomitant surgery (B = 14.40; P < 0.01), and higher VAS pain scores at intake (B = 0.15; P < 0.01) were associated with worse VAS pain scores postoperatively. Together, the variables explained 11% of the variance in mean VAS pain score at 3 months follow-up. Conclusions: This study confirms that surgical treatment for DQ significantly reduces patient-reported pain. Smoking, younger age, concomitant surgery, duration of complaints, and higher VAS pain scores at intake are associated with worse patient-reported pain 3 months after surgical release. However, the small effects suggest that these factors should not be considered the only important factors. CLINICAL QUESTION/LEVEL OF EVIDENCE: Risk, III.</p
Forearm rotation improves after corrective osteotomy in patients with symptomatic distal radius malunion
Objectives: Distal radius malunion can result in pain and functional complaints. One of the functional problems that can affect daily life is impaired forearm rotation. The primary aim of this study was to investigate the effect of corrective osteotomy for distal radius malunion on forearm rotation at 12 months after surgery. We secondarily studied the effect on grip strength, radiological measurements, and patient-reported outcome measurements (PROMs). Patients and methods: This cohort study analysed prospectively collected data of adult patients with symptomatic distal radius malunion. All patients underwent corrective osteotomy for malunion and were followed for 1 year. We measured forearm rotation (pronation and supination) and grip strength and analysed radiographs. PROMs consisted of the Patient-Rated Hand/Wrist Evaluation (PRWHE) questionnaire, Visual Analogue Scale for pain, and satisfaction with hand function. Results:Preoperative total forearm rotation was 112° (SD: 34°), of which supination of 49° (SD: 25°) was more impaired than pronation of 63° (SD: 17°). Twelve months after surgery, an unpaired Student's t-test showed a significant improvement of total forearm rotation to 142° (SD: 17°) (p < 0.05). Pronation improved to 72° (SD: 10°), and supination to 69° (SD: 13°) (p < 0.05). Grip strength, PROMs, as well as inclination and volar tilt on radiographs improved significantly during the first year after surgery (p < 0.05). Conclusion: In patients with reduced forearm rotation due to distal radius malunion, corrective osteotomy is an effective treatment that significantly improves forearm rotation. In addition, this intervention improves grip strength, the PRWHE-score, pain, and satisfaction with hand function.</p
Patient-Reported Outcomes and Function after Surgical Repair of the Ulnar Collateral Ligament of the Thumb
Purpose: The purpose of this study was to report prospectively collected patient-reported outcomes of patients who underwent open thumb ulnar collateral ligament (UCL) repair and to find risk factors associated with poor patient-reported outcomes. Methods: Patients undergoing open surgical repair for a complete thumb UCL rupture were included between December 2011 and February 2021. Michigan Hand Outcomes Questionnaire (MHQ) total scores at baseline were compared to MHQ total scores at three and 12 months after surgery. Associations between the 12-month MHQ total score and several variables (i.e., sex, injury to surgery time, K-wire immobilization) were analyzed. Results: Seventy-six patients were included. From baseline to three and 12 months after surgery, patients improved significantly with a mean MHQ total score of 65 (standard deviation [SD] 15) to 78 (SD 14) and 87 (SD 12), respectively. We did not find any differences in outcomes between patients who underwent surgery in the acute (<3 weeks) setting compared to a delayed setting (<6 months). Conclusions: We found that patient-reported outcomes improve significantly at three and 12 months after open surgical repair of the thumb UCL compared to baseline. We did not find an association between injury to surgery time and lower MHQ total scores. This suggests that acute repair for full-thickness UCL tears might not always be necessary. Type of study/level of evidence: Therapeutic II.</p
Multidrug-resistant tuberculosis treatment adherence in migrants: a systematic review and meta-analysis.
BACKGROUND: Multidrug-resistant tuberculosis (MDR-TB) is a growing concern in meeting global targets for TB control. In high-income low-TB-incidence countries, a disproportionate number of MDR-TB cases occur in migrant (foreign-born) populations, with concerns about low adherence rates in these patients compared to the host non-migrant population. Tackling MDR-TB in this context may, therefore, require unique approaches. We conducted a systematic review and meta-analysis to identify and synthesise data on MDR-TB treatment adherence in migrant patients to inform evidence-based strategies to improve care pathways and health outcomes in this group. METHODS: This systematic review and meta-analysis was conducted in line with PRISMA guidelines (PROSPERO 42017070756). The databases Embase, MEDLINE, Global Health and PubMed were searched to 24 May 2017 for primary research reporting MDR-TB treatment adherence and outcomes in migrant populations, with no restrictions on dates or language. A meta-analysis was conducted using random-effects models. RESULTS: From 413 papers identified in the database search, 15 studies reporting on MDR-TB treatment outcomes for 258 migrants and 174 non-migrants were included in the systematic review and meta-analysis. The estimated rate of adherence to MDR-TB treatment across migrant patients was 71% [95% confidence interval (CI) = 58-84%], with non-adherence reported among 20% (95% CI = 4-37%) of migrant patients. A key finding was that there were no differences in estimated rates of adherence [risk ratio (RR) = 1.05; 95% CI = 0.82-1.34] or non-adherence (RR = 0.97; 95% CI = 0.79-1.36) between migrants and non-migrants. CONCLUSIONS: MDR-TB treatment adherence rates among migrants in high-income low-TB-incidence countries are approaching global targets for treatment success (75%), and are comparable to rates in non-migrants. The findings highlight that only just over 70% of migrant and non-migrant patients adhere to MDR-TB treatment. The results point to the importance of increasing adherence in all patient groups, including migrants, with an emphasis on tailoring care based on social risk factors for poor adherence. We believe that MDR-TB treatment targets are not ambitious enough
The Influence of Illness Perception and Mental Health on Return to Work After Carpal Tunnel Release Surgery
Purpose: Although multiple factors influencing return to work after a carpal tunnel release (CTR) have been identified, little is known about the influence of psychological patient factors on return to work. Therefore, this study aimed to identify the psychological factors that play a role in the return to work after a CTR surgery. Methods: Patients who planned to undergo a CTR were asked to fill out the Brief Illness Perception Questionnaire and the Patient Health Questionnaire before surgery to measure their illness perceptions and mental health status, respectively. Return to work was defined as the time until returning to work for 50% of normal hours and was measured using a questionnaire at 6 weeks, 3 months, and 6 months. To identify associations between nonpsychological and psychological patient factors and the return to work after CTR surgery, a Cox proportional hazards model was constructed. Results: In total, 615 patients were included in our study. Six months after surgery, 91% of the patients returned to work. For the psychological patient factors, we found that increases of 1 point on the items of worrying about carpal tunnel syndrome and having faith preoperatively in a beneficial effect of the CTR surgery were associated with hazard ratios of 0.92 (95% confidence interval, 0.88–0.96) and 1.10 (95% confidence interval, 1.02–1.19), respectively, for returning to work in the first 6 months after surgery. An increase of 1 point on the depression subscale of the Patient Health Questionnaire was associated with a hazard ratio of 0.88 (95% confidence interval, 0.78–0.99) for returning to work in the first 6 months after surgery. Conclusions: Our study showed that multiple psychological patient factors are associated with return to work after a CTR surgery. Addressing these psychological factors before surgery might be a low-cost intervention to improve return to work after the CTR surgery. Type of study/level of evidence: Prognostic II
Does the association between abnormal anatomy of the skull base and cerebellar tonsillar position also exist in syndromic craniosynostosis?
Purpose: Cerebellar tonsillar herniation (TH) occurs frequently in syndromic craniosynostosis; however, the exact pathogenesis is unknown. This study evaluates the association between skull base deformities and TH in syndromic craniosynostosis. Methods: Retrospective study MRI study comparing syndromic craniosynostosis to controls. Measured parameters included clivus length, skull base angle, Boogard's angle, foramen magnum area, and cerebellar tonsillar position (TP). The association between skull base parameters and TP was evaluated with linear mixed models, correcting for age and risk factors for TH in craniosynostosis (hydrocephalus, intracranial hypertension, craniocerebral disproportion, and lambdoid synostosis). Results: Two hundred and eighty-two scans in 145 patients were included, and 146 scans in 146 controls. The clivus was smaller at birth, and its growth was retarded in all syndromes. The skull base angle was smaller at birth in Apert and Crouzon syndromes, and the evolution through time was normal. Boogard's angle was smaller at birth in Apert syndrome, and its evolution was disturbed in Apert and Saethre-Chotzen syndromes. The foramen magnum was smaller at birth in Crouzon and Saethre-Chotzen syndromes, and its growth was disturbed in Apert, Crouzon, and Saethre-Chotzen syndromes. TP was higher at birth in Apert syndrome, but lowered faster. In Crouzon syndrome, TP was lower at birth and throughout life. A smaller clivus and larger foramen magnum were associated with a lower TP in controls (p<0.001, p=0.007), and in Crouzon syndrome, this applied to only foramen magnum size (p=0.004). Conclusion: The skull base and its growth are significantly different in syndromic craniosynostosis compared to controls. However, only foramen magnum area is associated with TP in Crouzon syndrome
Are Patient Expectations and Illness Perception Associated with Patient-reported Outcomes from Surgical Decompression in de Quervain's Tenosynovitis?
BACKGROUND: Psychological factors such as depression, pain catastrophizing, kinesiophobia, pain anxiety, and more negative illness perceptions are associated with worse pain and function in patients at the start of treatment for de Quervain's tenosynovitis. Longitudinal studies have found symptoms of depression and pain catastrophizing at baseline were associated with worse pain after treatment. It is important to study patients opting for surgery for their condition because patients should choose surgical treatment based on their values rather than misconceptions. Psychological factors associated with worse patient-reported outcomes from surgery for de Quervain's tenosynovitis should be identified and addressed preoperatively so surgeons can correct any misunderstandings about the condition. QUESTION/PURPOSE: What preoperative psychosocial factors (depression, anxiety, pain catastrophizing, illness perception, and patient expectations) are associated with pain and function 3 months after surgical treatment of de Quervain's tenosynovitis after controlling for demographic characteristics? METHODS: This was a prospective cohort study of 164 patients who underwent surgery for de Quervain's tenosynovitis between September 2017 and October 2018 performed by 20 hand surgeons at 18 centers. Our database included 326 patients who underwent surgery for de Quervain's tenosynovitis during the study period. Of these, 62% (201 of 326) completed all baseline questionnaires and 50% (164 of 326) also completed patient-reported outcomes at 3 months postoperatively. We found no difference between those included and those not analyzed in terms of age, sex, duration of symptoms, smoking status, and workload. The mean ± SD age of the patients was 52 ± 14 years, 86% (141 of 164) were women, and the mean duration of symptoms was 13 ± 19 months. Patients completed the Patient-Rated Wrist Evaluation (PRWE), the VAS for pain and function, the Patient Health Questionnaire for symptoms of anxiety and depression, the Pain Catastrophizing Scale, the Credibility/Expectations Questionnaire, and the Brief Illness Perceptions questionnaire at baseline. Patients also completed the PRWE and VAS for pain and function at 3 months postoperatively. We used a hierarchical multivariable linear regression model to investigate the relative contribution of patient demographics and psychosocial factors to the pain and functional outcome at 3 months postoperatively. RESULTS: After adjusting for demographic characteristics, psychosocial factors, and baseline PRWE score, we found that only the patient's expectations of treatment and how long their illness would last were associated with the total PRWE score at 3 months postoperatively. More positive patient expectations of treatment were associated with better patient-reported pain and function at 3 months postoperatively (ß = -2.0; p < 0.01), while more negative patient perceptions of how long their condition would last were associated with worse patient-reported pain and function (timeline ß = 2.7; p < 0.01). The final model accounted for 31% of the variance in the patient-reported outcome at 3 months postoperatively. CONCLUSION: Patient expectations and illness perceptions are associated with patient-reported pain and functional outcomes after surgical decompression for de Quervain's tenosynovitis. Addressing misconceptions about de Quervain's tenosynovitis in terms of the consequences for patients and how long their symptoms will last should allow patients to make informed decisions about the treatment that best matches their values. Prospective studies are needed to investigate whether addressing patient expectations and illness perceptions, with decision aids for example, can improve patient-reported pain and function postoperatively in those patients who still choose surgery for de Quervain's tenosynovitis. LEVEL OF EVIDENCE: Level III, therapeutic study
Surgical Treatment Outcome of de Quervain's Disease: A Systematic Review and Meta-analysis
Background: Surgical release of the extensor retinaculum is performed as a treatment for de Quervain's (DQ) disease when conservative treatment fails. In the literature, there is no consensus about the effectiveness of a surgical release in patients with DQ, the complication rate, or which type of incision is superior. Therefore, a systematic review and meta-analysis were conducted. Methods: A systematic search was performed in Embase, Medline Ovid, Web of Science Core Collection, Cochrane, and Google Scholar. Articles regarding surgical treatment of DQ disease that reported outcome and complications were included. We extracted exact values of visual analog scale scores and percentages of patients who experienced pain at follow-up. Complications assessed were (sub) luxation, superficial radial nerve injuries, wound infections, and scar problems. Results: Twenty-one studies with a total of 939 patients were included. Five percent of these patients (95% CI 1%-18%) did not show complete remission of pain at follow-up. When pooled, the mean reduction in visual analog scale scores was 5.7 (95% CI 5.3-6.1) on a 0-10 scale. No difference in outcome between different types of surgery or incisions was seen. Based on the meta-analysis, the pooled complication rate was 11% (95% CI 5%-22%). Conclusions: Five percent of patients still have residual pain after surgical release of the first extensor compartment. Surgery type, as well as the type of incision, did not affect outcome or complication. Thus, surgical release of the extensor retinaculum for DQ disease is an effective treatment, regardless of the type of surgery
