BACKGROUND CONTEXT
Validity and responsiveness of the Patient-Reported Outcomes Measurement Information System (PROMIS) have been investigated in several orthopaedic subspecialties. PROMIS has shorter completion time and greater research flexibility for the heterogeneous adult spinal deformity (ASD) population versus the Oswestry Disability Index (ODI) and Scoliosis Research Society 22-item questionnaire (SRS-22r).PURPOSE
Evaluate the validity and responsiveness of PROMIS in ASD surgery, during the early postoperative period.DESIGN
Prospective, longitudinal study.PATIENT SAMPLE
One hundred twenty-three patients with complete SRS-22r and PROMIS data.OUTCOME MEASURES
Validity and responsiveness of PROMIS versus the ODI and SRS-22r.METHODS
We identified patients who completed SRS-22r, ODI, and PROMIS questionnaires. Spearman's correlation was used to assess validity, paired-samples t tests to assess responsiveness, and Cohen's d to assess measure of effect. The authors report no conflicts of interests. No funding was received in support of this study.RESULTS
One hundred twenty-three patients with SRS-22r and PROMIS data from the preoperative visit were included in the validity analysis. Seventy-six patients with preoperative and early postoperative (6-week to 3-month) data were included in the responsiveness analysis. The SRS-22r function, self-image, pain, and mental health scores were moderately to strongly correlated with the following PROMIS domains: physical function (r?=?0.53), satisfaction with participation in social roles (r?=?0.51), pain (r?=??0.60), and anxiety (r?=??0.73). All SRS-22r domains, PROMIS domains, and ODI scores changed significantly from preoperatively to postoperatively (p < 0.05). Compared with the SRS-22r, PROMIS showed superior responsiveness across all domains except self-image.CONCLUSIONS
Our results indicate that PROMIS is a valid measure with comparable responsiveness to that of the SRS-22r and ODI during the early period after ASD surgery. However, a domain that reflects how ASD patients perceive their self-image should be developed and validated. 相似文献2.

Background Context
Psychosocial risk factors may predispose to progression of back and neck pain to chronic pain or disability. Resilience (the ability to recover from stress) and pain self-efficacy (confidence that one can perform daily activities despite pain) are important psychometric properties shown to affect health and illness.Purpose
To examine the relationships among resilience, pain self-efficacy, and disability in spine patients.Design/Setting
Prospective, single-center orthopedic spine clinic.Patient Sample
One hundred and ninety five patients in a tertiary spine practice recruited between December 2016 and March 2017.Outcome Measures
Self-reported measures: Brief Resilience Scale (BRS), Pain Self-Efficacy Questionnaire 2 (PSEQ-2) Short Form, Neck Disability Index (NDI), and Oswestry Disability Index (ODI).Methods
A prospective study was conducted of new patients visiting an orthopedic spine clinic complaining of neck pain or low back pain, with or without radiculopathy. Enrolled patients completed a survey of demographic information, the six-question BRS, the two-question PSEQ-2 Short Form, and NDI or ODI for neck or back pain, respectively. The relationship between BRS and NDI or ODI was examined, and the relationship between PSEQ-2 and NDI or ODI was also examined.Results
A total of 195 patients were evaluated. After excluding those with incomplete NDI or ODI, 180 patients were included in the analysis (46.1% men [83/180]; mean age 53 [standard deviation: 17] years). 139 (77.2%) subjects complained of low back pain and 41 (22.8%) subjects complained of neck pain. BRS was strongly negatively correlated with NDI (r=?0.61, p<.0001) and moderately negatively correlated with ODI (r=?0.34, p<.0001). PSEQ-2 was strongly negatively correlated with NDI (r=?0.69, p<.0001) and strongly negatively correlated with ODI (r=?0.62, p<.0001). BRS was moderately positively correlated with PSEQ-2 (r=0.36, p<.0001). For the low back pain cohort, the correlation between PSEQ-2 and ODI was significantly greater than the correlation between BRS and ODI (p=.0003); this difference was not noted in the neck pain cohort (p=.34).Conclusions
Low resilience and low pain self-efficacy are both independently associated with greater functional disability in neck and low back pain patients. Spine surgeons may find it useful to incorporate the BRS and PSEQ-2 into preoperative assessment. Future studies should examine the utility of these simple validated questionnaires in predicting response to treatments, including surgical intervention. 相似文献3.

BACKGROUND CONTEXT
Previous studies suggest that a postoperative symptom state with Oswestry Disability Index (ODI)≤20 and pain Numeric Rating Scales (NRS)≤2 following surgery for lumbar degenerative conditions are reasonable thresholds for best outcomes in which patients will be unlikely to seek additional medical care or require additional health-care resources.PURPOSE
To identify prognostic factors that predict a “best outcome,” defined as postoperative ODI≤20 and pain NRS≤2 following fusion for lumbar degenerative conditions.STUDY DESIGN
Longitudinal observational cohort.PATIENT SAMPLE
A total of 396 patients from a single site enrolled in the Quality Outcomes Database who underwent fusion for lumbar degenerative conditions.Outcome Measures
Oswestry Disability Index, Back and Leg Pain NRS (0–10).METHODS
Collected and analyzed variables included age, sex, body mass index, American Society of Anesthesia grade, number of surgical levels, surgical time, preoperative ODI, preoperative back pain, preoperative leg pain, workmen compensation status, surgical approach, smoking status, and principal diagnosis.RESULTS
A total of 74 patients (19%) reported a minimal symptom state at 1-year postoperative (ODI≤20, back pain NRS≤2, and leg pain NRS≤2) and were included in the best outcomes group. Patients in the best outcomes group were older (62 vs. 57 years, p=.001), had lower preoperative ODI (43 vs. 56, p=.000), lower preoperative back pain (6.5 vs. 7.5, p=.000). They had fewer surgical levels (1.25 vs. 1.47, p=.005) and shorter operative times [OR] times (208 vs. 241 minutes, p=.002). They were more likely to have a preoperative diagnosis of spondylolisthesis or disc herniation and less likely to have a diagnosis of adjacent segment disease or mechanical disc collapse (p=.001). Stepwise forward regression analysis revealed diagnosis (p=.023, OR=0.75), age (p=.000, OR=1.04), baseline ODI (p=.000, OR=0.96), and number of levels (p=.019, OR=0.53) as predictive variables.CONCLUSION
Achieving a minimal symptom state, defined here as a postoperative ODI≤20 and pain NRS≤2, following fusion for lumbar degenerative conditions is more likely in an older patient with a lower baseline ODI undergoing a single level lumbar fusion for spondylolisthesis. 相似文献4.

BACKGROUND CONTEXT
Health-related quality of life (HRQOL) parameters have been shown to be reliable and valid in patients with adult spinal deformity (ASD). Minimum clinically important difference (MCID) has become increasingly important to clinicians in evaluating patients with a threshold of improvement that is clinically relevant.PURPOSE
To calculate MCID and minimum detectable change (MDC) values of total scores of the Core Outcome Measures Index (COMI), Oswestry Disability Index (ODI), Physical Component Summary (PCS), Mental Component Summary (MCS) of the Short Form 36 (SF-36), and Scoliosis Research Society 22R (SRS-22R) in surgically and nonsurgically treated ASD patients who have completed an anchor question at pretreatment and 1-year follow-up.STUDY DESIGN/SETTING
Prospective cohort.PATIENT SAMPLE
Surgical and nonsurgical patients from a multicenter ASD database.OUTCOME MEASURES
Self-reported HRQOL measures (COMI, ODI, SF-36, SRS-22R, and anchor question).METHODS
A total of 185 surgical and 86 nonsurgical patients from a multicenter ASD database who completed pretreatment and 1-year follow-up HRQOL scales and the anchor question at the first year follow-up were included. The anchor question was used to determine MCID for each HRQOL measure. MCIDs were calculated by an anchor-based method using latent class analysis (LCA) and MDCs by a distribution-based method.RESULTS
All differences between means of baseline and first year postoperative total score measures for all scales demonstrated statistically significant improvements in the overall population as well as the surgically treated patients but not in the nonsurgical group. The calculated MDC and MCID values of HRQOL parameters in the entire study population were 1.34 and 2.62 for COMI, 10.65 and 14.31 for ODI, 6.09 and 7.33 for SF-36 PCS, 6.14 and 4.37 for SF-36 MCS, and 0.42 and 0.71 for SRS-22R. The calculated MCID values for surgical and non-surgical treatment groups were 2.76 versus 1.20 for COMI, 14.96 versus 2.45 for ODI, 7.83 versus 2.15 for SF-36 PCS, 5.14 versus 2.03 for SF-36 MCS, and 0.94 versus 0.11 for SRS-22R; the MDC values for surgical and nonsurgical treatment groups were 1.22 versus 1.51 for COMI, 10.27 versus 9.45 for ODI, 5.16 versus 6.77 for SF-36 PCS, 6.05 versus 5.67 for SF-36 MCS, and 0.38 versus 0.43 for SRS-22R.CONCLUSIONS
This study has demonstrated that MCID calculations for the HRQOL scales in ASD using LCA yield values comparable to other studies that had used different methodologies. The most important finding was the significantly different MCIDs for COMI, ODI, SF-36 PCS and SRS-22 in the surgically and nonsurgically treated cohorts. This finding suggests that a universal MCID value, inherent to a specific HRQOL for an entire cohort of ASD may not exist. Use of different MCIDs for surgical and nonsurgical patients may be warranted. 相似文献5.

BACKGROUND
In modern clinical research, the accepted minimum follow-up for patient-reported outcome measures (PROMs) after lumbar spine surgery is 24 months, particularly after fusion. Recently, this minimum requirement has been called into question.PURPOSE
We aim to quantify the concordance of 1- and 2-year PROMs to evaluate the importance of long-term follow-up after elective lumbar spine surgery.STUDY DESIGN
Retrospective analysis of data from a prospective registry.PATIENT SAMPLE
We identified all patients in our prospective institutional registry who underwent degenerative lumbar spine surgery with complete baseline, 12-month, and 24-month follow-up for ODI and numeric rating scales for back and leg pain (NRS-BP and NRS-LP).OUTCOME MEASURES
Oswestry Disability Index (ODI) and NRS-BP and NRS-LP at 1 year and at 2 years.METHODS
We evaluated concordance of 1- and 2-year change scores by means of Pearson's product-moment correlation and performed logistic regression to assess if achieving the minimum clinically important difference (MCID) at 12 months predicted 24-month MCID. Odds ratios (OR) and their 95% confidence intervals (CI), as well as model areas-under-the-curve were obtained.RESULTS
A total of 210 patients were included. We observed excellent correlation among 12- and 24-month ODI (r?=?0.88), NRS-LP (r?=?0.76) and NRS-BP (r?=?0.72, all p <.001). Equal results were obtained when stratifying for discectomy, decompression, or fusion. Patients achieving 12-month MCID were likely to achieve 24-month MCID for ODI (OR: 3.3, 95% CI: 2.4–4.1), NRS-LP (OR: 2.99, 95% CI: 2.2–4.2) and NRS-BP (OR: 3.4, 95% CI: 2.7–4.2, all p <.001) with excellent areas-under-the-curve values of 0.81, 0.77, and 0.84, respectively. Concordance rates between MCID at both follow-ups were 87.2%, 83.8%, and 84.2%. A post-hoc power analysis demonstrated sufficient statistical power.CONCLUSIONS
Irrespective of the surgical procedure, 12-month PROMs for functional disability and pain severity accurately reflect those at 24 months. In support of previous literature, our results suggest that 12 months of follow-up may be sufficient for evaluating spinal patient care in clinical practice as well as in research. 相似文献6.
Selective blocking laminoplasty in cervical laminectomy and fusion to prevent postoperative C5 palsy
BACKGROUND CONTEXT
Cervical laminectomy and fusion (CLF) is a common surgical option for multilevel cord compression. Postoperative C5 palsy occurrence after CLF has been a vexing problem for spine physicians. The posterior shift of the cord following laminectomy has been implicated as a major factor for postoperative C5 palsy, but attempts by spine surgeons to mitigate excessive shift while providing sufficient decompression have not been well reported.PURPOSE
To compare the incidence of postoperative C5 palsy after performing selective blocking laminoplasty concurrently with CLF to those of conventional CLF.STUDY DESIGN
A retrospective comparative study of prospectively collected data.PATIENT SAMPLE
Of 116 cervical myelopathy patients with degenerative cervical myelopathy, ossification of the posterior longitudinal ligament, and multilevel disc herniation, 93 patients (69 in group A [CLF group] and 24 in group B [selective blocking laminoplasty with CLF, CLF-S group]) were included in the study.OUTCOME MEASURES
The primary outcome measure was the occurrence of postoperative C5 palsy. Secondary end points included (1) clinical outcomes based on pain intensity, neck disability index (NDI), Japanese Orthopaedic Association (JOA) score, (2) radiologic outcomes including cervical alignment and fusion rate at 1 year and hardware complications, and (3) perioperative data (hospital stay, blood loss, and operative times).METHODS
We compared the occurrence of postoperative C5 palsy, as well as clinical, radiologic, and surgical outcomes, between the two groups at 1-year follow-up.RESULTS
The patients in both groups were statistically similar between the groups with respect to demographic characteristics such as age, sex, smoking status, body mass index, preoperative pathology, surgical segments, and the degree of the cervical lordosis. Postoperative C5 palsy developed in 9 of 61 patients (14%) in group A and in 0 of 24 patients (0%) in group B (CLF-S group) (p=.03). Postoperative neck pain, NDI, and JOA improvement were not significantly different between the two groups (p=.93, 0.90, and 0.79, respectively). Perioperative data did not differ significantly between the two groups.CONCLUSIONS
This study showed that performing selective blocking laminoplasty might lead to reducing the incidence of postoperative C5 palsy in CLF surgery. 相似文献7.

BACKGROUND CONTEXT
The impact of Accountable Care Organizations (ACOs) on healthcare quality and outcomes, including morbidity, mortality, and readmissions, has not been substantially investigated, especially following spine surgery.PURPOSE
To evaluate the impact of ACO formation on postoperative outcomes in the 90-day period following spine surgery.STUDY DESIGN
Retrospective review of national Medicare claims data (2009–2014).PATIENT SAMPLE
Patients who underwent one of four lumbar spine surgical procedures in an ACO or non-ACO.OUTCOME MEASURES
The development of in-hospital mortality, complications or hospital readmission within 90 days of the surgical procedure.METHODS
The primary outcome measures included postsurgical complications and readmissions at 90 days following surgery. In-hospital mortality and 30-day outcomes were considered secondarily. The primary predictor variable consisted of ACO enrollment designation. Multivariable logistic regression analysis was utilized to adjust for confounders and determine the independent effect of ACO enrollment on postsurgical outcomes. The multivariable model included a propensity score adjustment that accounted for factors associated with the preferential enrollment of patients in ACOs, namely, sociodemographic characteristics, medical co-morbidities, hospital teaching status, bed size, and location.RESULTS
In all, there were 344,813 patients identified for inclusion in this analysis with 97% (n = 332,890) treated in non-ACOs and 3% (n = 11,923) in an ACO. Although modest changes were apparent across both ACOs and non-ACOs over the time-period studied, improvements were slightly more dramatic in non-ACOs leading to statistically significant differences in both 90-day complications and readmissions. Specifically, in the period 2012–2014, ACOs demonstrated an 18% increase in the odds of 90-day complications and a 14% elevation in the odds of 90-day readmissions when compared to non-ACOs. There was no difference in hospital mortality between ACOs and non-ACOs.CONCLUSIONS
Our study of Medicare data from 2009 to 2014 failed to demonstrate superior reductions in postoperative morbidity, mortality, and readmissions for beneficiaries treated in ACOs as compared to non-ACOs. These results indicate that meaningful changes in postoperative outcomes should not be anticipated based on organizational participation in ACOs at present. 相似文献8.
BACKGROUND
The pattern of linear graph schematized by visual analogue scale (VAS) score displaying pain worsening between 2 days and 2 weeks after selective nerve root block (SNRB) is called rebound pain.PURPOSE
The purpose of this study was to determine if sodium hyaluronate and carboxymethyl cellulose solution (HA-CMC sol) injection could reduce the occurrence of rebound pain at 3 days to 2 weeks after SNRB in patients with radiculopathy compared with injection with corticosteroids and local anesthetics alone.STUDY DESIGN/SETTING
Double blinded randomized controlled clinical trial.PATIENT SAMPLE
A total of 44 patients (23 of 24 patients in the Guardix group and 21 of 24 patients in the control group) who finished the follow-up session were subjects of this study.OUTCOME MEASUREMENT
Patients were asked to write down their average VAS pain scores daily for 12 weeks. Functional outcomes were assessed by Oswestry Disability Index, Roland Morris Disability Questionnaire , and Short Form-36.METHOD
A cocktail of corticosteroids, 1% lidocaine, 0.5% Bupivacaine, and 1 mL of normal saline was used for the control group whereas a cocktail of corticosteroids, 1% lidocaine, 0.5% Bupivacaine, and 1 mL of HA-CMC solution was used for the G group. Study participants were randomized into one of two treatment regimens. They were followed up for 3 months.RESULTS
VAS score at 2 weeks after the procedure was 4.19±1.32 in the control group, which was significantly (p<.05) higher than that (2.43±1.24) in the G group. VAS score at 6 weeks after the procedure was 4.00±1.23 in the control group and 3.22±1.45 in the G group, showing no significant (p=.077) difference between the two groups. There were no significant differences in functional outcomes at 6 or 12 weeks after the procedure.CONCLUSIONS
Compared with conventional cocktail used for SNRB, addition of HA-CMC sol showed effective control of rebound pain at 3 days to 2 weeks after the procedure. 相似文献9.

Background Context
Underlying cognitive factors have been found to influence patients’ symptom experience. Current evidence suggests that concomitant changes in appraisal must be taken into account to accurately interpret change as measured by standard spine patient-reported outcomes (PROs).Purpose
To investigate changes in patients’ minimally important differences (MID) over recovery from spinal surgery; whether and how cognitive appraisal processes are implicated in the change trajectories.Study Design/Setting
Longitudinal cohort study with up to 12 months follow-up.Patient Sample
Surgical patients (n?=?167) with a diagnosis of disc herniation or spinal stenosis.Outcome Measures
Standard spine patient-reported PROs were used (Rand-36, Oswestry Disability Index, Numerical Rating Scale for pain, PROMIS Pain Impact).Methods
This study was funded by the Feldberg Chair in Spinal Research, Sunnybrook Health Sciences Centre and the authors have no conflicts of interest. MID used an anchor technique and was computed by global assessment of change (GAC) grouping. Participants were binned into groups based on their GAC response patterns at all time points: Consistently better post-surgery, consistently worse post-surgery, and bouncers, whose GAC ratings fluctuate (ie, better-then-worse-then-better; or vice versa). Individuals’ longitudinal quality of life (QOL) and appraisal slope scores were computed. QOL-appraisal slopes’ correlations were computed by GAC group. Fisher's Z transformation tested the hypothesis that GAC groups differed in the QOL-appraisal relationship over time.Results
Moderate to large changes are recognized as clinically important in the early stages of recovery (ie, 6 weeks post-surgery), and over time smaller and smaller changes become important. The three pattern groups emphasized and deemphasized different standards of comparison over time, with the Better group emphasizing personal goals and the Worse and Bouncers deemphasizing doctors’ input. These group differences translated to differential relationships between PRO change and appraisal changes over time.Conclusions
The MID reflects increasingly subtle change over time in PROs. Appraisal may influence how patients experience the same (MID) change over time, with better outcomes associated with emphasizing long-term goals. PRO change seems to be driven by different standards of comparison. Potential avenues for clinical intervention are discussed. 相似文献10.

Background
Patient-reported outcome measures are being used increasingly to assess disease severity and response to surgery. The purpose of this study was to create and validate a patient-reported outcome measure for symptoms of thyroid enlargement and hyperparathyroidism, 2 conditions where the presence of preoperative symptoms and response to surgery is often questioned.Methods
A questionnaire reviewing common symptoms was developed from a literature review and expert opinion. Internal validity, reliability, and initial responsiveness to surgery were evaluated.Results
Patient-Reported Outcome Measure for Parathyroid and Thyroid Disease (PROMPT) consists of 30 items: 10 compressive items and 20 hyperparathyroidism items; we evaluated 302 surveys collected over 10 months. PROMPT showed high internal consistency for compressive and hyperparathyroid constructs (Cronbach's α 0.84 and 0.95). Constructs were scored from 0–100, with greater scores corresponding to increased severity of symptoms. Preoperatively, patients with a goiter demonstrated greater compressive scores compared with other thyroid patients and hyperparathyroid patients (goiter, 47.5; nodule/other, 38.4; hyperparathyroid, 29.8; P < .0001). PROMPT demonstrated high test–retest reliability with acceptable intraclass correlation coefficients for both compressive score and hyperparathyroid score (0.840 and 0.646). Hyperparathyroid scores improved 2 weeks after (48.6 postop, 44.0 preop, P?=?.0470).Conclusion
We validated a novel measure for symptoms of hyperparathyroidism and goiter. PROMPT demonstrates high internal consistency, test–retest reliability, and preliminary analysis, which suggests that it is sensitive to change after surgery. 相似文献11.
BACKGROUND CONTEXT
Patients with pyogenic vertebral osteomyelitis (PVO) are expected to have an increased risk of bone loss. Therefore, early bisphosphonate therapy would be clinically effective for PVO patients with osteoporosis.PURPOSE
This study aimed to investigate the effect of bisphosphonate on clinical outcomes of PVO patients with osteoporosis.STUDY DESIGN/SETTING
A retrospective comparative study.PATIENT SAMPLE
PVO patients with osteoporosis.OUTCOME MEASURES
Four events of interest for Cox proportional hazard model included surgical treatment, recurrence of infection, subsequent fracture of adjacent vertebral bodies, and death.METHODS
PVO patients were divided into three groups: group A (initiation of bisphosphonate within 6 weeks after PVO diagnosis), group B (initiation of bisphosphonate between 6 weeks and 3 months after PVO diagnosis), and group C (no treatment for osteoporosis). Cox proportional hazard model was used for the four events of interest.RESULTS
A total of 360 PVO patients with osteoporosis were investigated for the four events of interest. Group A had significantly lower hazard ratios for undergoing later (>6 weeks after diagnosis) surgery than group C (p?=?.014) despite similar occurrences of overall surgery. A significant difference was also observed in the occurrence of subsequent fractures at adjacent vertebral bodies (p?=?.001 for model 1 and p?=?.002 for model 2). Groups A and B had significantly lower hazard ratios for subsequent fracture than group C. No significant differences were observed in the hazard ratios of recurrence and death among the three groups.CONCLUSIONS
Early bisphosphonate treatment in PVO patients with osteoporosis was associated with a significantly lower occurrence of subsequent vertebral fracture at adjacent vertebral bodies and lower occurrence of subsequent surgery. 相似文献12.

BACKGROUND CONTEXT
Degenerative lumbar scoliosis (DLS) is an increasingly common spinal disorder of which current management is characterized by a substantial variety in treatment advice. To improve evidence-based clinical decision-making and increase uniformity and transparency of care, the Scoliosis Research Society established appropriateness criteria for surgery for DLS. In these criteria, however, the patient perspective was not formally incorporated. Since patient perspective is an increasingly important consideration in informed decision-making, embedding patient-reported outcome measures (PROMs) in the appropriateness criteria would allow for an objective and transparent patient-centered approach.PURPOSE
To evaluate the extent that patient perspective is integrated into the appropriateness criteria of surgery for DLS.STUDY DESIGN
Single center, retrospective, cohort study.PATIENT SAMPLE
150 patients with symptomatic degenerative lumbar scoliosis.Outcome Measures
The association between appropriateness for surgery and various PROMs [Visual Analogue Scale for pain, Short Form 36 (SF-36), Pain Catastrophizing Scale (PCS), Hospital Anxiety Depression Scale (HADS), and Oswestry Disability Index (ODI)].METHODS
Medical records of all patients with symptomatic DLS were reviewed and scored according to the appropriateness criteria. To assess the association between the appropriateness criteria and the validated PROMs, analysis of variance was used to test for differences in PROMS for each of the three categories resulting from the appropriateness criteria. To assess how well PROMs can discriminate between appropriate and inappropriate, we used a logistic regression analysis. Discriminative ability was subsequently determined by computing the area under the curve (AUC), resulting from the logistic regression analysis. Spearman rank analysis was used to establish a correlation pattern between the PROMs used and the appropriateness criteria.RESULTS
There was a significant association between the appropriateness of surgery and the PROMs. The discriminative ability for appropriateness of surgery for PROMs as a group was strong (AUC of 0.83). However, when considered in isolation, the predictive power of any individual PROMs was poor. The different categories of the appropriateness criteria significantly coincided with the PROMs used.CONCLUSION
There is a statistically significant association between the appropriateness criteria of surgery for DLS and PROMs. Implementation of PROMs into the appropriateness criteria may lead to more transparent, quantifiable and uniform clinical decision making for DLS. 相似文献13.

Background
Among the population of morbidly obese people, super-super-obese (SSO) individuals (body mass index >60 kg/m2) present a treatment challenge for bariatric surgeons.Objectives
To compare the long-term outcomes between laparoscopic sleeve gastrectomy (SG) and laparoscopic Roux-en-Y gastric bypass (RYGB) and to evaluate the efficacy of SG as a stand-alone bariatric procedure for SSO patients.Setting
University hospital, Paris, France.Methods
We retrospectively reviewed the data outcomes of 210 SSO patients who underwent SG or RYGB between January 2000 and December 2011. The 6-year follow-up data were analyzed and compared.Results
Follow-up data at 6 years were collected for 57.1% and 52.1% of patients in the SG group and RYGB groups, respectively. Both procedures were effective at promoting weight loss. Most weight loss was achieved at 24 months with both procedures. The average percent excess weight loss and change in body mass index of SG versus RYGB showed no significant differences at the 4-year follow-up. Except for sleep apnea, RYGB showed slightly better resolution of the evaluated co-morbidities. The composite endpoint of major short-term adverse events (<30 d) occurred in 11.7% of patients with RYGB and 6.4% of those with SG (P?=?.02). Postoperative complications were seen in 26% of RYGB patients and 16.1% of SG patients.Conclusions
SG as a primary procedure for SSO patients remains effective even though RYGB achieves better midterm outcomes. SG can be proposed as the primary-option p+rocedure. Further investigations are needed to identify the ideal procedure for patients with symptoms of gastroesophageal reflux disease. 相似文献14.

Background
The essence of enhanced recovery after surgery (ERAS) program is the multimodal approach, and many authors have demonstrated safety and feasibility in fast-track bariatric surgery.Objectives
The aim of this study was to evaluate the postoperative pain after the implementation of an ERAS protocol in Roux-en-Y gastric bypass and to compare it with the application of a standard care protocol.Setting
University Hospital Rey Juan Carlos, Madrid, Spain.Methods
A prospective randomized clinical trial of all the patients undergoing Roux-en-Y gastric bypass was performed. Patients were randomized into the following 2 groups: those patients after an ERAS program and those patients after a standard care protocol. Postoperative pain, nausea or vomiting, morbidity, mortality, hospital stay, and analytic acute phase reactants 24 hours after surgery were evaluated.Results
One hundred eighty patients were included in the study, 90 in each group. Postoperative pain (16 versus 37 mm; P < .001), nausea or vomiting (8.9% versus 2.2%; P?=?.0498), and hospital stay (1.7 versus 2.8 d; P < .001) were significantly lower in the ERAS group. There were no significant differences in complications, mortality, and readmission rates. White blood cell count, serum fibrinogen, and C reactive protein levels were significantly lower in the ERAS group 24 hours after surgery.Conclusion
The implementation of an ERAS protocol was associated with lower postoperative pain, reduced incidence of postoperative nausea or vomiting, lower levels of acute phase reactants, and earlier hospital discharge. Complications, reinterventions, mortality, and readmission rates were similar to that obtained after a standard care protocol. 相似文献15.

BACKGROUND CONTEXT
Surgical site infections (SSI) following spine surgery are debilitating complications to patients and costly to the healthcare system.PURPOSE
Review the impact and cost effectiveness of 5 SSI prevention interventions on SSI rates in an orthopedic spine surgery practice at a major quaternary healthcare system over a 10-year period.STUDY DESIGN
Retrospective observational study.PATIENT SAMPLE
All of the surgical patients of the 5 spine surgeons in our department over a 10-year period were included in this study.OUTCOME MEASURES
SSI rates per year, standardized infection ratios (SIR) for laminectomies and fusions during the most recent 3-year period, year of implementation, and frequency of use of the different interventions, cost of the techniques.METHODS
The SSI prevention techniques described in this paper include application of intrawound vancomycin powder, wound irrigation with dilute betadine solution, preoperative chlorhexidine gluconate scrubs, preoperative screening with nasal swabbing, and decolonization of S. aureus, and perioperative antibiotic administration. Our institution's infection prevention and control data were analyzed for the yearly SSI rates for the orthopedic spine surgery department from 2006 to 2016. In addition, our orthopedic spine surgeons were polled to determine with what frequency and duration they have been using the different SSI prevention interventions.RESULTS
SSI rates decreased from almost 6% per year the first year of observation to less than 2% per year in the final 6 years of this study. A SIR of less than 1.0 for each year was observed for laminectomies and fusions for the period from 2013 to 2016. All surgeons polled at our institution uniformly used perioperative antibiotics, Hibiclens scrub, and the nasal swab protocol since the implementation of these techniques. Some variability existed in the frequency and duration of betadine irrigation and application of vancomycin powder. A cost analysis demonstrated these methods to be nominal compared with the cost of treating a single SSI.CONCLUSIONS
It is possible to reduce SSI rates in spine surgery with easy, safe, and cost-effective protocols, when implemented in a standardized manner. 相似文献16.

BACKGROUND CONTEXT
Lumbar spinal stenosis (LSS) can impair blood flow to the spinal nerves giving rise to neurogenic claudication and limited walking ability. Reducing lumbar lordosis can increases the volume of the spinal canal and reduce neuroischemia. We developed a prototype LSS belt aimed at reducing lumbar lordosis while walking.PURPOSE
The aim of this study was to assess the short-term effectiveness of a prototype LSS belt compared to a lumbar support in improving walking ability in patients with degenerative LSS.STUDY DESIGN
This was a two-arm, double-blinded (participant and assessor) randomized controlled trial.PATIENT SAMPLE
We recruited 104 participants aged 50 years or older with neurogenic claudication, imaging confirmed degenerative LSS, and limited walking ability.OUTCOME MEASURES
The primary measure was walking distance measured by the self-paced walking test (SPWT) and the primary outcome was the difference in proportions among participants in both groups who achieved at least a 30% improvement in walking distance from baseline using relative risk with 95% confidence intervals.METHODS
Within 1 week of a baseline SPWT, participants randomized to the prototype LSS belt group (n=52) and those randomized to the lumbar support group (n=52) performed a SPWT that was conducted by a blinded assessor. The Arthritis Society funded this study ($365,000 CAN) with salary support for principal investigator funded by the Canadian Chiropractic Research Foundation ($500,000 CAN for 5 years).RESULTS
Both groups showed significant improvement in walking distance, but there was no significant difference between groups. The mean group difference in walking distance was ?74 m (95% CI: ?282.8 to 134.8, p=.49). In total, 62% of participants wearing the prototype LSS belt and 82% of participants wearing the lumbar support achieved at least 30% improvement in walking distance (relative risk, 0.7; 95% CI: 0.5–1.3, p=.43).CONCLUSIONS
A prototype LSS belt demonstrated significant improvement in walking ability in degenerative LSS but was no better than a lumbar support. 相似文献17.

BACKGROUND CONTEXT
Although 40% of adolescent idiopathic scoliosis (AIS) patients present with chronic back pain, the pathophysiology and underlying pain mechanisms remain poorly understood. We hypothesized that development of chronic pain syndrome in AIS is associated with alterations in pain modulatory mechanisms.PURPOSE
To identify the presence of sensitization in nociceptive pathways and to assess the efficacy of the diffuse noxious inhibitory control in patients with AIS presenting with chronic back pain.STUDY DESIGN
Cross-sectional study.PATIENT SAMPLE
Ninety-four patients diagnosed with AIS and chronic back pain.OUTCOME MEASURES
Quantitative sensory testing (QST) assessed pain modulation and self-reported questionnaires were used to assess pain burden and health-related quality of life.METHODS
Patients underwent a detailed pain assessment using a standard and validated quantitative sensory testing (QST) protocol. The measurements included mechanical detection thresholds (MDT), pain pressure threshold (PPT), heat pain threshold (HPT), heat tolerance threshold (HTT), and a conditioned pain modulation (CPM) paradigm. Altogether, these tests measured changes in regulation of the neurophysiology underlying the nociceptive processes based on the patient's pain perception. Funding was provided by The Louise and Alan Edwards Foundation and The Shriners Hospitals for Children.RESULTS
Efficient pain inhibitory response was observed in 51.1% of patients, while 21.3% and 27.7% had sub-optimal and inefficient CPM, respectively. Temporal summation of pain was observed in 11.7% of patients. Significant correlations were observed between deformity severity and pain pressure thresholds (p=.023) and CPM (p=.017), neuropathic pain scores and pain pressure thresholds (p=.015) and temporal summation of pain (p=.047), and heat temperature threshold and pain intensity (p=.048).CONCLUSIONS
Chronic back pain has an impact in the quality of life of adolescents with idiopathic scoliosis. We demonstrated a high prevalence of impaired pain modulation in this group. The association between deformity severity and somatosensory dysfunction may suggest that spinal deformity can be a trigger for abnormal neuroplastic changes in this population contributing to chronic pain syndrome. 相似文献18.

BACKGROUND CONTEXT
Pedicle screw loosening is common after spinal fusion and can be associated with pseudoarthrosis and pain. With suspicion of screw loosening on standard radiographs, CT is currently considered the advanced imaging modality of choice. MRI with new metal artifact reduction techniques holds potential to be sensitive in detection of screw loosening. The sensitivity and specificity of either of the imaging modalities are yet clear.PURPOSE
To evaluate the sensitivity and specificity of three different image modalities (standard radiographs, CT, and MRI) for detection of pedicle screw loosening.STUDY DESIGN/SETTING
Cross-sectional diagnostic study.PATIENT SAMPLE
Forty-one patients (159 pedicle screws) undergoing revision surgeries after lumbar spinal fusion between August 2014 and April 2017 with preoperative radiographs, CT, and MRI with spinal metal artifact reduction (STIR WARP and TSE high bandwidth sequences).OUTCOME MEASURES
Sensitivity and specificity in detection of screw loosening for each imaging modality.METHODS
Screw torque force was measured intraoperatively and compared with preoperative screw loosening signs such as peri-screw edema in MRI and peri-screw osteolysis in CT and radiographs. A torque force of less than 60 Ncm was used to define a screw as loosened.RESULTS
Sensitivity and specificity in detection of screw loosening was 43.9% and 92.1% for MRI, 64.8% and 96.7% for CT, and 54.2% and 83.5% for standard radiographs, respectively.CONCLUSIONS
Despite improvement of MRI with metal artifact reduction MRI technique, CT remains the modality of choice. Even so, CT fails to detect all loosened pedicle screws. 相似文献19.

Background Context
Red flags are questions typically ascertained by providers to screen for serious underlying spinal pathologies. The utility of patient-reported red flags in guiding clinical decision-making for spine care, however, has not been studied.Purpose
The aim of this study was to quantify the sensitivity and specificity of patient-reported red flags in predicting the presence of serious spinal pathologies.Study Design
This was a retrospective nested case-control study.Patient Sample
This study consisted of 120 patients with International Classification of Diseases, Ninth Revision, Clinical Modification codes for spinal pathologies and 380 randomly selected patients, from a population of 4,313 patients seen at a large tertiary care spine clinic between October 9, 2013 and June 30, 2014.Outcome Measures
The presence of patient-reported red flags and red flags obtained from medical records was verified for chart review. The spinal pathology (ie, malignancy, fractures, infections, or cauda equina syndrome) was noted for each patient.Methods
The sensitivity and specificity of patient-reported red flags for detecting serious spinal pathologies were calculated from data obtained from the 500 patients. Youden's J was used to rank performance. Agreement between patient-reported red flags and those obtained from medical record review was assessed via Cohen's kappa statistic.Results
“History of cancer” was the best performing patient-reported red flag to identify malignancy (sensitivity=0.75 [95% confidence intervals, CI 0.53–0.90], specificity=0.79 [95% CI 0.75–0.82]). The best performing patient-reported red flag for fractures was the presence of at least one of the following: “Osteoporosis,” “Steroid use,” and “Trauma” (sensitivity=0.59 [95% CI 0.44–0.72], specificity=0.65 [95% CI 0.60–0.69]). The prevalence of infection and cauda equina diagnoses was insufficient to gauge sensitivity and specificity. Red flags from medical records had better performance than patient-reported red flags. There was poor agreement between patient red flags and those obtained from medical record review.Conclusions
Patient-reported red flags had low sensitivity and specificity for identification of serious pathologies. They should not be used in insolation to make treatment decisions, although they may be useful to prompt further probing to determine if additional investigation is warranted. 相似文献20.
