Background Exacerbations of COPD (ECOPD) have a major impact on patients and healthcare systems across the world. Precise estimates of the global burden of ECOPD on mortality and hospital readmission are needed to inform policy makers and aid preventive strategies to mitigate this burden. The aims of the present study were to explore global in-hospital mortality, post-discharge mortality and hospital readmission rates after ECOPD-related hospitalisation using an individual patient data meta-analysis (IPDMA) design. Methods A systematic review was performed identifying studies that reported in-hospital mortality, postdischarge mortality and hospital readmission rates following ECOPD-related hospitalisation. Data analyses were conducted using a one-stage random-effects meta-analysis model. This study was conducted and reported in accordance with the PRISMA-IPD statement. Results Data of 65 945 individual patients with COPD were analysed. The pooled in-hospital mortality rate was 6.2%, pooled 30-, 90- and 365-day post-discharge mortality rates were 1.8%, 5.5% and 10.9%, respectively, and pooled 30-, 90- and 365-day hospital readmission rates were 7.1%, 12.6% and 32.1%, respectively, with noticeable variability between studies and countries. Strongest predictors of mortality and hospital readmission included noninvasive mechanical ventilation and a history of two or more ECOPD-related hospitalisations < 12 months prior to the index event. Conclusions This IPDMA stresses the poor outcomes and high heterogeneity of ECOPD-related hospitalisation across the world. Whilst global standardisation of the management and follow-up of ECOPD-related hospitalisation should be at the heart of future implementation research, policy makers should focus on reimbursing evidence-based therapies that decrease (recurrent) ECOPD.

Background: Electronic clinical decision support systems (eCDSS), such as the ‘Systematic Tool to Reduce Inappropriate Prescribing’ Assistant (STRIPA), have become promising tools for assisting general practitioners (GPs) with conducting medication reviews in older adults. Little is known about how GPs perceive eCDSS-assisted recommendations for pharmacotherapy optimization. The aim of this study was to explore the implementation of a medication review intervention centered around STRIPA in the ‘Optimising PharmacoTherapy In the multimorbid elderly in primary CAre’ (OPTICA) trial. Methods: We used an explanatory mixed methods design combining quantitative and qualitative data. First, quantitative data about the acceptance and implementation of eCDSS-generated recommendations from GPs (n = 21) and their patients (n = 160) in the OPTICA intervention group were collected. Then, semi-structured qualitative interviews were conducted with GPs from the OPTICA intervention group (n = 8), and interview data were analyzed through thematic analysis. Results: In quantitative findings, GPs reported averages of 13 min spent per patient preparing the eCDSS, 10 min performing medication reviews, and 5 min discussing prescribing recommendations with patients. On average, out of the mean generated 3.7 recommendations (SD=1.8). One recommendation to stop or start a medication was reported to be implemented per patient in the intervention group (SD=1.2). Overall, GPs found the STRIPA useful and acceptable. They particularly appreciated its ability to generate recommendations based on large amounts of patient information. During qualitative interviews, GPs reported the main reasons for limited implementation of STRIPA were related to problems with data sourcing (e.g., incomplete data imports), preparation of the eCDSS (e.g., time expenditure for updating and adapting information), its functionality (e.g., technical problems downloading PDF recommendation reports), and appropriateness

01 februari 2023, Contains fulltext : 291044.pdf (Publisher’s version ) (Open Access), AIMS: The aim of this study was to assess the clinical and radiological results of patients who were revised using a custom-made triflange acetabular component (CTAC) for component loosening and pelvic discontinuity (PD) after previous total hip arthroplasty (THA). METHODS: Data were extracted from a single centre prospective database of patients with PD who were treated with a CTAC. Patients were included if they had a follow-up of two years. The Hip Disability and Osteoarthritis Outcome Score (HOOS), modified Oxford Hip Score (mOHS), EurQol EuroQoL five-dimension three-level (EQ-5D-3L) utility, and Numeric Rating Scale (NRS), including visual analogue score (VAS) for pain, were gathered at baseline, and at one- and two-year follow-up. Reasons for revision, and radiological and clinical complications were registered. Trends over time are described and tested for significance and clinical relevance. RESULTS: A total of 18 females with 22 CTACs who had a mean age of 73.5 years (SD 7.7) were included. A significant improvement was found in HOOS (p < 0.0001), mOHS (p < 0.0001), EQ-5D-3L utility (p = 0.003), EQ-5D-3L NRS (p = 0.013), VAS pain rest (p = 0.008), and VAS pain activity (p < 0.0001) between baseline and final follow-up. Minimal clinically important improvement in mOHS and the HOOS Physical Function Short Form (HOOS-PS) was observed in 16 patients (73%) and 14 patients (64%), respectively. Definite healing of the PD was observed in 19 hips (86%). Complications included six cases with broken screws (27%), four cases (18%) with bony fractures, and one case (4.5%) with sciatic nerve paresthesia. One patient with concurrent bilateral PD had revision surgery due to recurrent dislocations. No revision surgery was performed for screw failure or implant breakage. CONCLUSION: CTAC in patients with THA acetabular loosening and PD can result in stable constructs and significant improvement in functioning and health-related quality of life at two years' follow-up.

Item does not contain fulltext, BACKGROUND: Optimization of perioperative pain interventions in lumbar spine surgery could reduce the incidence of acute and persistent postoperative pain and opioid consumption. Standardization in early outcome measurement provides a solid foundation for future clinical and research practices and should be integrated in core outcome sets for long-term treatment outcome evaluations. This scoping review provides an overview of outcomes used when evaluating early perioperative pain interventions after lumbar spine surgery. OBJECTIVES: To create an overview of outcome domains and measurement instruments previously used in research on perioperative pain management for degenerative lumbar spine surgery. EVIDENCE REVIEW: A scoping review was performed to identify articles comprising outcome evaluations in adult patients who undergo degenerative lumbar spine surgery, mentioning perioperative pain interventions. 75 articles were included for review. Data on study characteristics, outcome domains and measurement instruments were extracted and structured using the three-tiered hierarchy of Porter. FINDINGS: 12 outcome domains were identified: pain intensity (93.3%), adverse events (76%), analgesic consumption (70.7%), length of stay (52%), patient satisfaction (24%), daily functioning (22.7%), (early) mobilization (22.7%), quality of life (12%), mortality (9.3%), quality of recovery (6.7%), physical function (4%), and quality of sleep (2.7%). 63 corresponding measurement instruments were found. CONCLUSIONS: This review portrays an extensive overview of outcome measurements used in perioperative pain management in lumbar spine surgery. A lack of consensus on the set of indicators exists. This scoping review is a call for action to create consensus on how to evaluate perioperative pain interventions in degenerative lumbar spine surgery.

01 september 2022, Contains fulltext : 288514.pdf (Publisher’s version ) (Open Access), STUDY DESIGN: Retrospective cohort study. OBJECTIVES: No consensus exists among surgeons on which radiologic method to prefer for the assessment of curve flexibility in spinal deformity. The objective of this study was to evaluate the difference in curve correction on supine traction radiographs versus prone side bending radiographs. METHODS: A retrospective analysis of idiopathic scoliosis (IS), degenerative idiopathic scoliosis (DIS) and de novo degenerative lumbar scoliosis (DNDLS) patients was performed on supine traction as well as prone bending films (when available). Age, weight, traction force, diagnosis and Cobb angles of the primary and secondary curves were extracted. Differences in curve correction (percentages) on traction versus prone bending radiographs were analyzed for the primary and secondary curve. Subgroup analyses were performed for the 3 different diagnoses. RESULTS: In total, 170 patients were eligible for inclusion. 43 were diagnosed with IS, 58 with DIS and 69 with DNDLS. For the primary curve, greater curve correction was obtained with bending in the DNDLS group (P < 0.001). In the DIS group, there was a trend toward more correction on bending (P = 0.054). In de IS group no difference was found. For the secondary curve, bending showed more curve correction in the IS and DIS group (P = 0.002 and P <0.001). No difference was found in the DNDLS group. CONCLUSION: Compared to traction radiographs, bending radiographs better serve the purpose of curve flexibility assessment of IS, DIS and DNDLS spinal deformity, despite the fact that patients are exposed to more radiation.

Contains fulltext : 251122.pdf (Publisher’s version ) (Open Access), OBJECTIVES: No evidence-based treatment exists for adult spinal deformity (ASD) patients with chronic low back pain (CLBP). AIM OF THIS STUDY: evaluate a combined physical and psychological programme (CPPP) for ASD patients with CLBP and to compare this with a non-ASD-cohort with CLBP. METHODS: Data were extracted from the database of CLBP-patients for whom surgery is not an option and completed CPPP. Two cohorts were selected: an ASD-cohort (n = 80) based on a Cobb angle of > 10° and a consecutive age- and gender-matched non-ASD-cohort (n = 240). PRIMARY OUTCOME: functional status (Oswestry Disability Index; ODI). SECONDARY OUTCOMES: pain intensity, self-efficacy and quality of life. ASSESSMENTS: pre and post treatment, one-month and one-year follow-up (FU). CLINICAL RELEVANCE: minimal important clinical change (MCIC; ODI 10 points), patient acceptable symptom state (PASS; ODI ≤ 22). RESULTS: Demographics ASD-cohort: 79% female, mean age 50.9 (± 14.1) years, mean CLBP duration 15.5 (± 12.5) years, mean Cobb angle 21.4 (± 9.4)°. Non-ASD-cohort: not significantly different. Both cohorts improved in functional status (F[1,318] = 142.982, p < .001; r = 0.31). The ASD-cohort improved from mean ODI 39.5(± 12.0) at baseline to mean ODI 31.8(± 16.5) at one-year FU. CLINICAL RELEVANCE: 51% of the ASD patients reached MCIC and 33% reached a PASS. An interaction effect is shown between time and both cohorts (F[1,318] = 8.2, p = .004; r = 0.03); however, not clinically relevant. All secondary outcomes: improvement at one-year FU. CONCLUSION: This is the first study showing beneficial outcomes of a non-surgical treatment in selected ASD patients with longstanding CLBP. Improvement is shown in functional status, and appeared equivalent to the non-ASD cohort. LEVEL OF EVIDENCE 1: Diagnostic: individual cross-sectional studies with the consistently applied reference standard and blinding.

Item does not contain fulltext, PURPOSE: For fusion surgery in adolescent idiopathic scoliosis (AIS) consensus exists that a 2-year radiographic follow-up assessment is needed. This standard lacks empirical evidence. The purpose of this study was to investigate the radiographic follow-up after corrective surgery in AIS, from pre-until 2 years postoperative. METHODS: In this historical cohort study, 63 patients surgically treated for AIS, age ≤ 25 years, with 2-year radiographic follow-up, were enrolled. The primary outcome measure was the major Cobb angle. Secondary outcomes were coronal and sagittal spino-pelvic parameters, including proximal junction kyphosis (PJK) and distal adding-on. Change over time was analyzed using a repeated measures ANOVA. RESULTS: The major curve Cobb angle showed a statistically significant change for pre- to 1 year postoperative, but not for 1- to 2-year follow-up. Seven out of 63 patients did show a change exceeding the error of measurement (5°) from 1- to 2-year follow-up (range -8° to +7°), of whom 2 patients showed curve progression and 5 showed improvement. PJK or distal adding-on was not observed. CONCLUSIONS: No statistically significant changes in major curve Cobb angle were found during postsurgical follow-up, or in adjacent non-fused segments. The findings of this study are not supportive for routine radiographs 2 years after fusion surgery in AIS patients.

01 juni 2021, Contains fulltext : 245062.pdf (Publisher’s version ) (Open Access), Background and purpose - Custom triflange acetabular components (CTACs) are suggested as good solutions for large acetabular defects in revision total hip arthroplasty. However, high complication rates have been reported and most studies are of limited quality. This prospective study evaluates the performance of a CTAC in patients with large acetabular defects including pelvic discontinuity.Patients and methods - Prospectively collected data of 49 consecutive patients (50 hips), who underwent an acetabular revision with a CTAC were analyzed. Follow-up (FU) was 2 years. The median age of the patients was 68 years (41-89) and 41 were women. Primary outcomes were re-revision of the CTAC and differences between the modified Oxford Hip Score (mOHS) preoperatively and at 2-year follow-up. Secondary outcomes included several patient-reported outcomes (PROMs), radiological results, complications, and a comparison between hips with and without pelvic discontinuity (PD).Results - 1 patient (1 hip) was lost to the 2-year FU. No CTAC needed re-revision. The preoperative and 2-year FU mOHS were available in 40 hips and improved statistically significantly. All of the other secondary outcomes improved over time. 5 hips (of 45 with radiological 2-year FU) had loosening of screws. 8 hips had complications, including 3 persistent wound leakage, 3 pelvic fractures, and 1 dislocation. The mOHS and complication rate were similar in hips with and without PD.Interpretation - Reconstruction of large acetabular defects with and without PD with this CTAC showed good improvement in patient-reported daily functioning, high patient-reported satisfaction, few complications, and no re-revisions at 2-year FU.
