- Abstract
Summary: Hip fractures are associated with significant healthcare costs. In frail institutionalized patients, the costs of nonoperative management are less than operative management with comparable short-term quality of life. Nonoperative management of hip fractures in patients at the end of life should be openly discussed with SDM. Purpose: The aim was to describe healthcare use with associated costs and to determine cost-utility of nonoperative management (NOM) versus operative management (OM) of frail institutionalized older patients with a proximal femoral fracture. Methods: This study included institutionalized patients with a limited life expectancy aged ≥ 70 years who sustained a proximal femoral fracture in the Netherlands. Costs of hospital- and nursing home care were calculated. Quality adjusted life years (QALY) were calculated based on EuroQol-5D-5L utility scores at day 7, 14, and 30 and at 3 and 6 months. The incremental cost-effectiveness ratio (ICER) was calculated from a societal perspective. Results: Of the 172 enrolled patients, 88 (51%) patients opted for NOM and 84 (49%) for OM. NOM was associated with lower healthcare costs at 6 months (NOM; €2425 (SD 1.030), OM; €9325 (SD 4242), p < 0.001). The main cost driver was hospital stay (NOM; €738 (SD 841) and OM; €3140 (SD 2636)). The ICER per QALY gained in the OM versus NOM was €76,912 and exceeded the threshold of €20,000 per QALY. The gained QALY were minimal in the OM group in patients who died within 14- and 30-day post-injury, but OM resulted in more than triple the costs. Conclusion: OM results in significant higher healthcare costs, mainly due to the length of hospital stay. For frail patients at the end of life, NOM of proximal femoral fractures should be openly discussed in SDM conversations due to the limited gain in QoL. Trial registration.

- Abstract
Background The course and different characteristics of acute and posttraumatic stress disorder (ASD, PTSD) in trauma populations are unclear. Objective The aims were to identify longitudinal trajectories of PTSD, to establish a risk profile for ASD and PTSD based on patients’ sociodemographic, clinical, and psychological characteristics, and to study the effect of ASD and dissociation on PTSD during 12 months after trauma. Method Patients completed questionnaires after inclusion and at 3, 6, 9, and 12 months afterwards. Trajectories were identified using repeated measures latent class analysis (RMLCA). The risk profile was based on a ranking of importance of each characteristic using Cohen’s d effect sizes and odds ratios. The impact of ASD and dissociation on PTSD was examined using logistic regression analyses. Results Altogether, 267 patients were included. The mean age was 54.0 (SD = 16.1) and 62% were men. The prevalence rate of ASD was approximately 21.7% at baseline, and 36.1% of trauma patients exhibited PTSD at 12 months after injury. Five trajectories were identified: (1) no PTSD symptoms, (2) mild, (3) moderate, (4) subclinical, and (5) severe PTSD symptoms. These trajectories seemed to remain stable over time. Compared with patients in other trajectories, patients with ASD and (subclinical) PTSD were younger and scored higher on anxiety, depressive symptoms, neuroticism, and trait anxiety. Regarding dissociation symptoms, inability to recall memories about the event was significantly more present than an altered sense of reality, (105 (40.7%) versus 56 (21.7%), p = .031), although that symptom had the strongest likelihood for PTSD. Patients with dissociation were significantly at risk for PTSD than patients without dissociation (OR = 4.82; 95%CI: 1.91–12.25). Conclusions Psychological factors characterized ASD and trajectories of PTSD during 12 months post-trauma. Healthcare providers who are aware

- Abstract
Background The course and corresponding characteristics of quality of life (QOL) domains in trauma population are unclear. Our aim was to identify longitudinal QOL trajectories and determine and predict the sociodemographic, clinical, and psychological characteristics of trajectory membership in physical trauma patients using a biopsychosocial approach. Methods Patients completed a questionnaire set after inclusion, and at 3, 6, 9, and 12 months follow-up. Trajectories were identified using repeated-measures latent class analysis. The trajectory characteristics were ranked using Cohen’s d effect size or phi coefficient. Results Altogether, 267 patients were included. The mean age was 54.1 (SD = 16.1), 62% were male, and the median injury severity score was 5.0 [2.0—9.0]. Four latent trajectories were found for psychological health and environment, five for physical health and social relationships, and seven trajectories were found for overall QOL and general health. The trajectories seemed to remain stable over time. For each QOL domain, the identified trajectories differed significantly in terms of anxiety, depressive symptoms, acute stress disorder, post-traumatic stress disorder, Neuroticism, trait anxiety, Extraversion, and Conscientiousness. Discussion Psychological factors characterized the trajectories during 12 months after trauma. Health care providers can use these findings to identify patients at risk for impaired QOL and offer patient-centered care to improve QOL.

- Abstract
Background Injury can have physical, psychological and social consequences. It is unclear which factors have an impact on patients’ wellbeing after injury. This study aimed to explore, using focus groups, patients’ experiences and wellbeing after injury and which factors, impede or facilitate patients’ wellbeing. Methods Trauma patients, treated in the shock room of the Elisabeth-TweeSteden Hospital, the Netherlands, participated in focus groups. Purposive sampling was used. Exclusion criteria were younger than 18 years old, severe traumatic brain injury, dementia, and insufficient knowledge of the Dutch language. The interviews were recorded, transcribed verbatim, and analyzed using coding technique open, axial, and selective coding, based on phenomenological approach. Results Six focus groups (3 to 7 participants) were held before data saturation was reached. In total, 134 patients were invited, 28 (21%) agreed to participate (Median age: 59.5; min. 18 –max. 84). Main reasons to decline were fear that the discussion would be too confronting or patients experienced no problems regarding the trauma or treatment. Participants experienced difficulties on physical (no recovery to pre-trauma level), psychological (fear of dying or for permanent limitations, symptoms of posttraumatic stress disorder, cognitive dysfunction), social (impact on relatives and social support) wellbeing. These are impeding factors for recovery. However, good communication, especially clarity about the injury and expectations concerning recovery and future perspectives could help patients in surrendering to care. Patients felt less helpless when they knew what to expect. Conclusions This is the first study that explored patients’ experiences and wellbeing after injury. Patients reported that their injury had an impact on their physical, psychological, and social wellbeing up to 12 months after injury. Professionals with the knowledge of consequences af

- Abstract
Summary: Patients with hip fractures experience reduced health-related quality of life and have a reduced life expectancy. Patients’ utilization of healthcare leads to costs to society. The results of the study can be used in future economic evaluations of treatments for hip fractures. Purpose: Hip fractures are associated with high mortality, reduced quality of life, and increased healthcare utilization, leading to an economic burden to society. The purpose of this study is to determine the burden of illness of hip fractures in elderly Dutch patients for specific time periods after surgery. Methods: Patients with a hip fracture above the age of 65 were included in the study. In the 1-year period after surgery, patients were asked to complete a set of questionnaires pre-injury (retrospectively), and 1 week, 1 month, 3 months, 6 months and 12 months after surgery. The set of questionnaires included the Euroqol 5D (EQ-5D-3L), the iMTA Medical Consumption Questionnaire (iMCQ) and iMTA Productivity Cost Questionnaire (iPCQ). Health-related quality of life was calculated using Dutch tariffs. Costs were calculated using the methodology described in the Dutch costing manual. Results: Approximately 20% of patients with a hip fracture died within 1 year. Health-related quality of life was significantly reduced compared to pre-injury values, and patients did not recover to their pre-injury values within 1 year. Total costs in the first year after injury were €27,573, of which 10% were due to costs of the procedure (€2706). Total follow-up costs (€24,876) were predominantly consisting of healthcare costs. Monthly costs decreased over time. Conclusions: Hip fractures lead to a burden to patients, resulting from mortality and health-related quality of life reductions, and to society, due to (healthcare) costs. The results of this study can be used in future economic evaluations.

Contains fulltext : 215550.pdf (publisher's version ) (Open Access), BACKGROUND: Proximal femoral fractures are strongly associated with morbidity and mortality in elderly patients. Mortality is highest among frail institutionalized elderly with both physical and cognitive comorbidities who consequently have a limited life expectancy. Evidence based guidelines on whether or not to operate on these patients in the case of a proximal femoral fracture are lacking. Practice variation occurs, and it remains unknown if nonoperative treatment would result in at least the same quality of life as operative treatment. This study aims to determine the effect of nonoperative management versus operative management of proximal femoral fractures in a selected group of frail institutionalized elderly on the quality of life, level of pain, rate of complications, time to death, satisfaction of the patient (or proxy) and the caregiver with the management strategy, and health care consumption. METHODS: This is a multicenter, observational cohort study. Frail institutionalized elderly (70 years or older with a body mass index < 18.5, a Functional Ambulation Category of 2 or lower pre-trauma, or an American Society of Anesthesiologists score of 4 or 5), who sustained a proximal femoral fracture are eligible to participate. Patients with a pathological or periprosthetic fractures and known metastatic oncological disease will be excluded. Treatment decision will be reached following a structured shared decision process. The primary outcome is quality of life (Euro-QoL; EQ-5D-5 L). Secondary outcome measures are quality of life measured with the QUALIDEM, pain level (PACSLAC), pain medication use, treatment satisfaction of patient (or proxy) and caregivers, quality of dying (QODD), time to death, and direct medical costs. A cost-utility and cost-effectiveness analysis will be done, using the EQ-5D utility score and QUALIDEM score, respectively. Non-inferiority of nonoperative treatment is assumed with a limit of 0.15 on the EQ-5D score. Data will be acquired

- Abstract
Introduction The Girdlestone resection arthroplasty (GRA) is a salvage procedure for a recurrent or persistent prosthetic joint infection of the hip. This procedure negatively impacts the functional outcome and presumably also diminishes health status (HS) and quality of life (QOL). However, studies investigating the QOL after GRA are lacking. This cross-sectional study compares patients with a Girdlestone situation after an infected total hip prosthesis with a normative population with regard to HS and QOL. Methods Patients with a permanent GRA were suitable to be enrolled in the study. Subjects completed the World Health Organization Quality of life (WHOQOL-BREF) and the EuroQol 5 dimension 3 level version (EQ-5D-3L). Scores were compared with data from the normal population, from patients with a lower limb amputations and data from patients with a myocardial infarction. ResultsSixty-three patients who underwent GRA between January 2000 and March 2017 completed the questionnaire. The median time between the GRA and competing the questionnaire was 48 months (4 -436). All WHOQOL-BREF domain scores were significantly lower in GRA patients compared to the normative data (p<0.001), patients with myocardial infarction or lower limb amputation. EQ-5D-3L results showed that HS was significantly impaired in GRA patients when compared to normative data (p<0.001) and also impaired when compared to data from lower limb amputations and myocardial infarctions. Conclusion HS and QOL scores in patients with a permanent Girdlestone situation after an infected hip prosthesis are significantly lower than Dutch normative scores. Patients with a permanent Girdlestone situation scored even lower on HS than patients with a lower limb amputation or a myocardial infarction.

- Abstract
Background: Injury, medical treatment, and rehabilitation can have major impacts on patients’ wellbeing. About 25-33% of the patients experience an acute stress disorder (ASD) or a posttraumatic stress disorder (PTSD) after injury. ASD is a relatively new diagnosis. Therefore, knowledge about patients’ experiences, the course of ASD and PTSD, and who is at risk for developing ASD or PTSD is lacking. Objective: The aims of this multi-method study are to explore patients’ experiences with injury (and their care) using a focus group study. Then, in the observational study, different courses of ASD, PTSD, and quality of life will be examined. In addition, this study will examine if these courses could be characterized by socio-demographic, clinical, and psychological variables. Consequently, a risk profile will be developed to determine which patients are at risk for developing ASD or PTSD during the 12 months after injury. Methods: Trauma patients treated in the shock room (in 2015) of the Elisabeth-TweeSteden Hospital will share their experiences with injury in the focus group study. Open, axial, and selective coding will be used to analyze the data. Concerning the observational study, patients treated in the shock room (during 2016 and 2017, Elisabeth-TweeSteden Hospital and Erasmus Medical Centre) will be asked to participate. The inclusion period is 12 months. Participants will complete the Impact of Event Scale-Revised, MINI-plus, the Hospital Anxiety and Depression Scale, and the World Health Organization Quality of Life-BREF after inclusion and at 3, 6, 9, and 12 months after injury. The NEO-Five Factor Inventory and the State-Trait Anxiety Inventory-Trait are completed after inclusion only. Repeated measures of latent class analysis and linear mixed models will be used to examine the research aims. Results: This project was funded in August 2015 by ZonMw.

- Abstract
Item does not contain fulltext, INTRODUCTION: Trauma is a major public health problem worldwide that leads to high medical and societal costs. Overall, improved understanding of the full spectrum of the societal impact and burden of injury is needed. The main purpose of the Brabant Injury Outcome Surveillance (BIOS) study is to provide insight into prevalence, predictors and recovery patterns of short-term and long-term health-related quality of life (HRQoL) and costs after injury. MATERIALS AND METHODS: This is a prospective, observational, follow-up cohort study in which HRQoL, psychological, social and functional outcome, and costs after trauma will be assessed during 24 months follow-up within injured patients admitted in 1 of 10 hospitals in the county Noord-Brabant, the Netherlands. Data will be collected by self-reported questionnaires at 1 week (including preinjury assessment), and 1, 3, 6, 12 and 24 months after injury. If patients are not capable of filling out the questionnaires, proxies will be asked to participate. Also, information about mechanism and severity of injury, comorbidity and indirect and direct costs will be collected. Mixed models will be used to examine the course of HRQoL, functional and psychological outcome, costs over time and between different groups, and to identify predictors for poor or good outcome. RELEVANCE: This study should make a substantial contribution to the international collaborative effort to assess the societal impact and burden of injuries more accurately. The BIOS results will also be used to develop an outcome prediction model for outcome evaluation including, besides the classic fatal, non-fatal outcome. TRIAL REGISTRATION NUMBER: NCT02508675.

- Abstract
Purpose: This prospective study aimed to identify the different trajectories of quality of life (QOL) in patients with distal radius fractures (DRF) and ankle fractures (AF). Secondly, it was examined if subgroups could be characterized by sociodemographic, clinical, and psychological variables. Methods: Patients (n = 543) completed the World Health Organization Quality of Life assessment instrument-Bref (WHOQOL-Bref), the pain, coping, and cognitions questionnaire, NEO-five factor inventory (neuroticism and extraversion), and the state-trait anxiety inventory (short version) a few days after fracture (i.e., pre-injury QOL reported). The WHOQOL-Bref was also completed at three, six, and 12 months post-fracture. Latent class trajectory analysis (i.e., regression model) including the Step 3 method was performed in Laten

- Abstract
Item does not contain fulltext, INTRODUCTION: Trauma is a major public health problem worldwide that leads to high medical and societal costs. Overall, improved understanding of the full spectrum of the societal impact and burden of injury is needed. The main purpose of the Brabant Injury Outcome Surveillance (BIOS) study is to provide insight into prevalence, predictors and recovery patterns of short-term and long-term health-related quality of life (HRQoL) and costs after injury. MATERIALS AND METHODS: This is a prospective, observational, follow-up cohort study in which HRQoL, psychological, social and functional outcome, and costs after trauma will be assessed during 24 months follow-up within injured patients admitted in 1 of 10 hospitals in the county Noord-Brabant, the Netherlands. Data will be collected by self-reported questionnaires at 1 week (including preinjury assessment), and 1, 3, 6, 12 and 24 months after injury. If patients are not capable of filling out the questionnaires, proxies will be asked to participate. Also, information about mechanism and severity of injury, comorbidity and indirect and direct costs will be collected. Mixed models will be used to examine the course of HRQoL, functional and psychological outcome, costs over time and between different groups, and to identify predictors for poor or good outcome. RELEVANCE: This study should make a substantial contribution to the international collaborative effort to assess the societal impact and burden of injuries more accurately. The BIOS results will also be used to develop an outcome prediction model for outcome evaluation including, besides the classic fatal, non-fatal outcome. TRIAL REGISTRATION NUMBER: NCT02508675.

Purpose This prospective study aimed to identify the different trajectories of quality of life (QOL) in patients with distal radius fractures (DRF) and ankle fractures (AF). Secondly, it was examined if subgroups could be characterized by sociodemographic, clinical, and psychological variables. MethodsPatients (n = 543) completed the World Health Organization Quality of Life assessment instrument-Bref (WHOQOL-Bref), the pain, coping, and cognitions questionnaire, NEO-five factor inventory (neuroticism and extraversion), and the state-trait anxiety inventory (short version) a few days after fracture (i.e., pre-injury QOL reported). The WHOQOL-Bref was also completed at three, six, and 12 months post-fracture. Latent class trajectory analysis (i.e., regression model) including the Step 3 method was performed in Latent Gold 5.0. Results The number of classes ranged from three to five for the WHOQOL-Bref facet and the four domains with a total variance explained ranging from 71.6 to 79.4%. Sex was only significant for physical and psychological QOL (p < 0.05), whereas age showed significance for overall, physical, psychological, and environmental QOL (p < 0.05). Type of treatment or fracture type was not significant (p > 0.05). Percentages of chronic comorbidities were 1.8 (i.e., social QOL) to 4.5 (i.e., physical QOL) higher in the lowest compared to the highest QOL classes. Trait anxiety, neuroticism, extraversion, pain catastrophizing, and internal pain locus of control were significantly different between QOL trajectories (p < 0.05). Conclusions The importance of a biopsychosocial model in trauma care was confirmed. The different courses of QOL after fracture were defined by several sociodemographic and clinical variables as well as psychological characteristics. Based on the identified characteristics, patients at risk for lower QOL may be recognized earlier by health care providers offering opportunities for monitoring and

- Abstract
In this cross-sectional study the psychometric properties are examined of the adapted Dutch translation of the Short Musculoskeletal Function Assessment (SMFA) questionnaire in severely injured patients (ISS. >. 15). Patients and methods: Patients (N = 173) completed the SMFA, the World Health Organization Quality of Life assessment instrument-BREF (WHOQOL-BREF), the Dutch Impact of Event Scale (IES), the Hospital Anxiety and Depression Scale (HADS) and the Cognitive Failure Questionnaire (CFQ). The Abbreviated Injury Score and the Injury Severity Score were established to determine the injured body area and the severity of the injuries. Exploratory factor analysis (method: PAF) was performed. Correlations were calculated between our SMFA factors and scores on the WHOQOL-BREF, IES, HADS and CFQ. The SMFA scores of the factors Upper extremity dysfunction and Lower extremity dysfunction were compared between subgroups of patients with and without injuries in respectively the upper extremities and the lower extremities. For responsiveness analysis, data were compared with the baseline SMFA measurement of a reference group. Results: A three-factor structure was found: Lower extremity dysfunction, Upper extremity dysfunction, and Emotion. Strong correlations between the SMFA and the other questionnaires were found. Patients with injury of the lower extremities had significantly higher scores on the factor Lower extremity dysfunction than patients without injury of the lower extremities (p = 0.017). In none of the factors, a significant difference in mean scores was found between patients with and without injury of the upper extremities. Severely injured patients had significantly higher SMFA scores than the reference group (p < 0.001). Conclusion: The adapted Dutch translation of the SMFA showed good psychometric properties in severely injured patients. It appeared to be useful to get a general overview of patients' Health Status as well as patients' Health Related Quali

- Abstract
Purpose: The aim of this prospective study was to describe the course of health status (HS), health-related quality of life, and quality of life (QOL) in patients with lower extremity fractures (LEF) up to 6 months post-fracture. Methods: Patients (n = 171; age range 18–100 years) completed the World Health Organization Quality of Life assessment instrument-Bref (WHOQOL-Bref) and the Short Musculoskeletal Function Assessment questionnaire (SMFA) at time of diagnosis (i.e., pre-injury status), 1 week, and 6 months post-fracture. Linear mixed modeling was performed. Results: Interaction effects of time with treatment were detected for the WHOQOL-Bref facet Overall QOL and General health (p = .002) and Physical health (p = .003). Patients did not return to their pre-injury Physical health, Psychological health, and Environment 6 months post-fracture (p < .05). No effects were found for Social relationships. The SMFA subscale Lower extremity dysfunction showed main effects for time and treatment (p < .0001) with full recovery at 6 months (p = .998). An interaction effect of time with treatment was found for Daily life consequences (p < .0001) with nonoperatively treated patients showing full recovery (p = 1.00), whereas surgically treated patients did not (p = .002). Conclusions: Six months after LEF, patients still experienced impaired physical and psychological health on the WHOQOL-Bref compared to their pre-injury status. However, patients showed full recovery on SMFA Lower extremity dysfunction, indicating that the choice of the questionnaire influences the derived conclusions. LEF did not affect satisfaction with social relationships.

- Abstract
1 maart 2014, Item does not contain fulltext, OBJECTIVES: There is substantial variation in the classification and management of scapula fractures. The first purpose of this study was to analyze the interobserver reliability of the OTA/AO classification and the New International Classification for Scapula Fractures. The second purpose was to assess the proportion of agreement among orthopaedic surgeons on operative or nonoperative treatment. DESIGN: Web-based reliability study. SETTING: Independent orthopaedic surgeons from several countries were invited to classify scapular fractures in an online survey. PARTICIPANTS: One hundred three orthopaedic surgeons evaluated 35 movies of three-dimensional computerized tomography reconstruction of selected scapular fractures, representing a full spectrum of fracture patterns. MAIN OUTCOME MEASUREMENTS: Fleiss kappa (kappa) was used to assess the reliability of agreement between the surgeons. RESULTS: The overall agreement on the OTA/AO classification was moderate for the types (A, B, and C, kappa = 0.54) with a 71% proportion of rater agreement (PA) and for the 9 groups (A1 to C3, kappa = 0.47) with a 57% PA. For the New International Classification, the agreement about the intraarticular extension of the fracture (Fossa (F), kappa = 0.79) was substantial and the agreement about a fractured body (Body (B), kappa = 0.57) or process was moderate (Process (P), kappa = 0.53); however, PAs were more than 81%. The agreement on the treatment recommendation was moderate (kappa = 0.57) with a 73% PA. CONCLUSIONS: The New International Classification was more reliable. Body and process fractures generated more disagreement than intraarticular fractures and need further clear definitions.

- Abstract
01 maart 2014, Item does not contain fulltext, OBJECTIVES: There is substantial variation in the classification and management of scapula fractures. The first purpose of this study was to analyze the interobserver reliability of the OTA/AO classification and the New International Classification for Scapula Fractures. The second purpose was to assess the proportion of agreement among orthopaedic surgeons on operative or nonoperative treatment. DESIGN: Web-based reliability study. SETTING: Independent orthopaedic surgeons from several countries were invited to classify scapular fractures in an online survey. PARTICIPANTS: One hundred three orthopaedic surgeons evaluated 35 movies of three-dimensional computerized tomography reconstruction of selected scapular fractures, representing a full spectrum of fracture patterns. MAIN OUTCOME MEASUREMENTS: Fleiss kappa (kappa) was used to assess the reliability of agreement between the surgeons. RESULTS: The overall agreement on the OTA/AO classification was moderate for the types (A, B, and C, kappa = 0.54) with a 71% proportion of rater agreement (PA) and for the 9 groups (A1 to C3, kappa = 0.47) with a 57% PA. For the New International Classification, the agreement about the intraarticular extension of the fracture (Fossa (F), kappa = 0.79) was substantial and the agreement about a fractured body (Body (B), kappa = 0.57) or process was moderate (Process (P), kappa = 0.53); however, PAs were more than 81%. The agreement on the treatment recommendation was moderate (kappa = 0.57) with a 73% PA. CONCLUSIONS: The New International Classification was more reliable. Body and process fractures generated more disagreement than intraarticular fractures and need further clear definitions.

- Abstract
Purpose This prospective study examined the psychometric properties of the adapted Dutch translation of the Short Musculoskeletal Function Assessment (SMFA) questionnaire in patients with isolated unilateral lower fracture (LEF) or upper extremity fracture (UEF). Patients (N = 458) completed the SMFA, WHOQOL-BREF, and the RAND-36 at time of diagnosis (i.e. pre-injury status), 1, and 2 weeks post-fracture. Principal axis factoring was performed, and Cronbach's alpha coefficients (alpha) and intra-class correlation coefficients (ICC) were calculated. Furthermore, Pearson's product-moment correlations (r), paired t tests, and standardized response means (SRM) were calculated. A three-factor structure was found: Lower extremity dysfunction, Upper extremity dysfunction, and Daily life consequences. This structure was different for patients with LEF versus UEF. ICCs ranged from .68 to .90, and alpha varied from .81 to .95. The correlations between the SMFA and, respectively, the RAND-36 and WHOQOL-BREF were small to large depending on the SMFA factor combined with fracture location. Responsiveness was confirmed (p < .0001; SRM ranging from .28 to 1.71). The SMFA has good psychometric properties in patients with fractures. Patients with UEF and LEF could not be regarded as a homogenous group. The development of separate SMFA modules should be considered.

European Trade Study Group, 11 september 2009, Contains fulltext : 167451.pdf (author's version ) (Open Access), We take the Fujita & Thisse (2003) growth-cum-geography model to investigate the implications of seeing social ties as an important reason for the generation of knowledge. Moreover, we model migration as an important channel through which the distance decay effect of cross-regional knowledge spillovers materialize. Our results show that in such a setting the full agglomeration of high-skilled workers that are engaged in R&D activities is not a straightforward outcome. The equilibrium with an equally dispersed high-skilled labour force is a stable migration equilibrium, while regions with a larger initial share of high-skilled workers will only attract more workers when migration rates are not too high. When social ties are important in generating knowledge and knowledge spillovers, the full agglomeration of high-skilled workers in one region is not at all certain. In such a case, growth is however not optimal. As such, the trade-off between reaching optimal growth and equal distribution of economic activity remains.
