RESUMO

We present a novel technique for classification of skull deformities due to most common craniosynostosis. We included 5 children of every group of the common craniosynostoses (scaphocephaly, brachycephaly, trigonocephaly, and right- and left-sided anterior plagiocephaly) and additionally 5 controls. Our outline-based classification method is described, using the software programs OsiriX, MeVisLab, and Matlab. These programs were used to identify chosen landmarks (porion and exocanthion), create a base plane and a plane at 4 cm, segment outlines, and plot resulting graphs. We measured repeatability and reproducibility, and mean curves of groups were analyzed. All raters achieved excellent intraclass correlation scores (0.994-1.000) and interclass correlation scores (0.989-1.000) for identifying the external landmarks. Controls, scaphocephaly, trigonocephaly, and brachycephaly all have the peak of the forehead in the middle of the curve (180°). In contrary, in anterior plagiocephaly, the peak is shifted (to the left of graph in right-sided and vice versa). Additionally, controls, scaphocephaly, and trigonocephaly have a high peak of the forehead; scaphocephaly has the lowest troughs; in brachycephaly, the width/frontal peak ratio has the highest value with a low frontal peak.Conclusion: We introduced a preliminary study showing an objective and reproducible methodology using CT scans for the analysis of craniosynostosis and potential application of our method to 3D photogrammetry. What is Known: • Diagnosis of craniosynostosis is relatively simple; however, classification of craniosynostosis is difficult and current techniques are not widely applicable. What is New: • We introduce a novel technique for classification of skull deformities due to craniosynostosis, an objective and reproducible methodology using CT scans resulting in characteristic curves. The method is applicable to all 3D-surface rendering techniques. • Using external landmarks and curve analysis, specific and characteristic curves for every type of craniosynostosis related to the specific skull deformities are found.

RESUMO

Our health care system is constantly adapting to change at an increasingly rapid pace. Unavoidably, this also applies to the field of medical education. As a result, clinical teaching teams face the challenging task of successfully implementing the proposed changes in daily practice. It goes without saying that implementing change takes time and that you need to be patient. However, a successful change process needs more than that. Change models or strategies could offer a helping hand. The questionnaire Specialty training's Organizational Readiness for curriculum Change (STORC) is a tool aiming to do just that. With a focus on readiness for change, this questionnaire tries to support implementation efforts in PGME. Additionally, since change is a team effort, it focusses on clinical teaching teams particularly. In this paper, we offer a practical guide for clinical teaching teams on how to deal with any concerns or hurdles detected in any of the core elements of readiness for change, in order to smoothen and support the educational change processes these teams are confronted with.

RESUMO

BACKGROUND: The field of postgraduate medical education (PGME) is continuously evolving as a result of social demands and advancing educational insights. Change experts contend that organizational readiness for change (ORC) is a critical precursor for successful implementation of change initiatives. However, in PGME, assessing change readiness is rarely considered while it could be of great value for managing educational change such as curriculum change. Therefore, in a previous Delphi study the authors developed an instrument for assessing ORC in PGME: Specialty Training's Organizational Readiness for curriculum Change (STORC). In this study, the psychometric properties of this questionnaire were further explored. METHODS: In 2015, STORC was distributed among clinical teaching teams in the Netherlands. The authors conducted a confirmatory factor analysis on the internal factor structure of STORC. The reliability of the measurements was estimated by calculating Cronbach's alpha for all sub-scales. Additionally, a behavioral support-for-change measure was distributed as well to assess correlations with change-related behavior. RESULTS: In total, the STORC questionnaire was completed by 856 clinical teaching team members from 39 specialties. Factor analysis led to the removal of 1 item but supported the expected factor structure with very good fit for the other 43 items. Supportive behavior was positively correlated to a higher level of ORC. DISCUSSION: In this study, additional steps to collect validity evidence for the STORC questionnaire were taken successfully. The final subscales of STORC represent the core components of ORC in the literature. By breaking down this concept into multiple measurable aspects, STORC could help to enable educational leaders to diagnose possible hurdles in implementation processes and to perform specifically targeted interventions when needed.

RESUMO

INTRODUCTION: Curriculum change and innovation are inevitable parts of progress in postgraduate medical education (PGME). Although implementing change is known to be challenging, change management principles are rarely looked at for support. Change experts contend that organizational readiness for change (ORC) is a critical precursor for the successful implementation of change initiatives. Therefore, this study explores whether assessing ORC in clinical teaching teams could help to understand how curriculum change takes place in PGME. METHODS: Clinical teaching teams in hospitals in the Netherlands were requested to complete the Specialty Training's Organizational Readiness for curriculum Change, a questionnaire to measure ORC in clinical teaching teams. In addition, change-related behavior was measured by using the "behavioral support-for-change" measure. A two-way analysis of variance was performed for all response variables of interest. RESULTS: In total, 836 clinical teaching team members were included in this study: 288 (34.4%) trainees, 307 (36.7%) clinical staff members, and 241 (28.8%) program directors. Overall, items regarding whether the program director has the authority to lead scored higher compared with the other items. At the other end, the subscales "management support and leadership," "project resources," and "implementation plan" had the lowest scores in all groups. DISCUSSION: The study brought to light that program directors are clearly in the lead when it comes to the implementation of educational innovation. Clinical teaching teams tend to work together as a team, sharing responsibilities in the implementation process. However, the results also reinforce the need for change management support in change processes in PGME.

RESUMO

BACKGROUND: Surgery for sagittal synostosis aims at correction of skull shape and restoration of growth potential. Small cranial volume is associated with raised intracranial pressure (ICP). Although many techniques have been described, information on postoperative volume related to early and late remodeling is lacking. METHODS: Between 2004 and 2008, a total of 95 patients were collected who underwent either early extended strip craniectomy or late total cranial remodeling according to age of presentation. Volume was measured on three-dimensional (3D) photogrammetry. Volume measurements were related to cranial index (CI), head circumference (HCsd), and signs of raised ICP. In a small subset of patients, volume measurements on 3D photogrammetry were assessed for inter- and intrarater reliability and compared to 3D computed tomography (CT). RESULTS: Volume was increased in all patients before and after surgery compared to normative values. Postoperatively, late total cranial remodeling resulted in a slightly larger volume than early extended strip craniectomy. Volume measurements showed a good correlation with HCsd (0.67) and a poor relationship with CI (0.13). Headache occurred more frequently in patients with a lower cranial volume. Although papilledema and reoperation showed the same trend, the numbers were too small for statistical analysis. Reproducibility of volume measurements on 3D photogrammetry was high, as was the correlation with measurements on CT. CONCLUSION: Late total cranial remodeling results in a larger postoperative volume, as measured on 3D photogrammetry, than extended strip craniectomy. Clinical signs of raised ICP occur more frequently in patients with a smaller volume. To measure volume, 3D photogrammetry is a good alternative to CT.

RESUMO

BACKGROUND: In postgraduate medical education (PGME), programs have been restructured according to competency-based frameworks. The scale and implications of these adjustments justify a comprehensive implementation plan. Organizational Readiness for Change (ORC) is seen as a critical precursor for a successful implementation of change initiatives. Though, ORC in health care settings is mostly assessed in small scale settings and in relation to new policies and practices rather than educational change. Therefore our aim with this work was to develop an instrument to asses Specialty Training's Organizational Readiness for curriculum Change (STORC). METHODS: A Delphi procedure was conducted to examine the applicability of a preliminary questionnaire in PGME, which was based on existing instruments designed for business and health care organizations. The 41 panellists (19 trainees and 22 supervisors from 6 specialties) from four different countries who were confronted with an apparent curriculum change, or would be in the near future, were asked to rate the relevance of a 89-item web-based questionnaire with regard to changes in specialty training on a 5-point Likert scale. Furthermore, they were invited to make qualitative comments on the items. RESULTS: In two rounds the 89-item preliminary questionnaire was reduced to 44 items. Items were either removed, kept, adapted or added based on individual item scores and qualitative comments. In the absence of a gold standard, this Delphi procedure was considered complete when the overall questionnaire rating exceeded 4.0 (scale 0-5). The overall item score reached 4.1 in the second round, meeting our criteria for completion of this Delphi procedure. CONCLUSIONS: This Delphi study describes the initial validating step in the development of an instrument to asses Specialty Training's Organisational Readiness for curriculum Change (STORC). Since ORC is measured on various subscales and presented as such, its strength lies in analysing these subscales. The latter makes it possible for educational leaders to identify and anticipate on hurdles in the implementation process and subsequently optimize efforts for successful curriculum change.

RESUMO

PURPOSE: National culture has been shown to play a role in curriculum change in medical schools, and business literature has described a similar influence of organizational culture on change processes in organizations. This study investigated the impact of both national and organizational culture on successful curriculum change in medical schools internationally. METHOD: The authors tested a literature-based conceptual model using multilevel structural equation modeling. For the operationalization of national and organizational culture, the authors used Hofstede's dimensions of culture and Quinn and Spreitzer's competing values framework, respectively. To operationalize successful curriculum change, the authors used two derivates: medical schools' organizational readiness for curriculum change developed by Jippes and colleagues, and change-related behavior developed by Herscovitch and Meyer. The authors administered a questionnaire in 2012 measuring the described operationalizations to medical schools in the process of changing their curriculum. RESULTS: Nine hundred ninety-one of 1,073 invited staff members from 131 of 345 medical schools in 56 of 80 countries completed the questionnaire. An initial poor fit of the model improved to a reasonable fit by two suggested modifications which seemed theoretically plausible. In sum, characteristics of national culture and organizational culture, such as a certain level of risk taking, flexible policies and procedures, and strong leadership, affected successful curriculum change. CONCLUSIONS: National and organizational culture influence readiness for change in medical schools. Therefore, medical schools considering curriculum reform should anticipate the potential impact of national and organizational culture.

RESUMO

PURPOSE: Because successful change implementation depends on organizational readiness for change, the authors developed and assessed the validity of a questionnaire, based on a theoretical model of organizational readiness for change, designed to measure, specifically, a medical school's organizational readiness for curriculum change (MORC). METHOD: In 2012, a panel of medical education experts judged and adapted a preliminary MORC questionnaire through a modified Delphi procedure. The authors administered the resulting questionnaire to medical school faculty involved in curriculum change and tested the psychometric properties using exploratory and confirmatory factor analysis, and generalizability analysis. RESULTS: The mean relevance score of the Delphi panel (n = 19) reached 4.2 on a five-point Likert-type scale (1 = not relevant and 5 = highly relevant) in the second round, meeting predefined criteria for completing the Delphi procedure. Faculty (n = 991) from 131 medical schools in 56 countries completed MORC. Exploratory factor analysis yielded three underlying factors-motivation, capability, and external pressure-in 12 subscales with 53 items. The scale structure suggested by exploratory factor analysis was confirmed by confirmatory factor analysis. Cronbach alpha ranged from 0.67 to 0.92 for the subscales. Generalizability analysis showed that the MORC results of 5 to 16 faculty members can reliably evaluate a school's organizational readiness for change. CONCLUSIONS: MORC is a valid, reliable questionnaire for measuring organizational readiness for curriculum change in medical schools. It can identify which elements in a change process require special attention so as to increase the chance of successful implementation.

RESUMO

BACKGROUND: Earlier studies suggested national culture to be a potential barrier to curriculum reform in medical schools. In particular, Hofstede's cultural dimension 'uncertainty avoidance' had a significant negative relationship with the implementation rate of integrated curricula. AIMS: However, some schools succeeded to adopt curriculum changes despite their country's strong uncertainty avoidance. This raised the question: 'How did those schools overcome the barrier of uncertainty avoidance?' METHOD: Austria offered the combination of a high uncertainty avoidance score and integrated curricula in all its medical schools. Twenty-seven key change agents in four medical universities were interviewed and transcripts analysed using thematic cross-case analysis. RESULTS: Initially, strict national laws and limited autonomy of schools inhibited innovation and fostered an 'excuse culture': 'It's not our fault. It is the ministry's'. A new law increasing university autonomy stimulated reforms. However, just this law would have been insufficient as many faculty still sought to avoid change. A strong need for change, supportive and continuous leadership, and visionary change agents were also deemed essential. CONCLUSIONS: In societies with strong uncertainty avoidance strict legislation may enforce resistance to curriculum change. In those countries opposition by faculty can be overcome if national legislation encourages change, provided additional internal factors support the change process.

RESUMO

Integrated curricula have been implemented in medical schools all over the world. However, among countries different relative numbers of schools with integrated curricula are found. This study aims to explore the possible correlation between the percentage of medical schools with integrated curricula in a country and that country's cultural characteristics. Curricula were defined as not integrated if in the first 2 years of the program at least two out of the three monodisciplinary courses Anatomy, Physiology and Biochemistry were identified. Culture was defined using Hofstede's dimensions Power distance, Uncertainty avoidance, Masculinity/Femininity, and Individualism/Collectivism. Consequently, this study had to be restricted to the 63 countries included in Hofstede's studies which harbored 1,195 medical schools. From each country we randomly sampled a maximum of 15 schools yielding 484 schools to be investigated. In total 91% (446) of the curricula were found. Correlation of percent integrated curricula and each dimension of culture was determined by calculating Spearman's Rho. A high score on the Power distance index and a high score on the Uncertainty avoidance index correlated with a low percent integrated curricula; a high score on the Individualism index correlated with a high percent integrated curricula. The percentage integrated curricula in a country did not correlate with its score on the Masculinity index. National culture is associated with the propensity of medical schools to adopt integrated medical curricula. Consequently, medical schools considering introduction of integrated and problem-based medical curricula should take into account dimensions of national culture which may hinder the innovation process.

RESUMO

CONTEXT: There is an evident misbalance in the frequency of medical schools with problem-based learning (PBL) curricula in northern versus southern Europe. This study explores the hypothesis that national culture influences the flexibility of (medical) schools in terms of their propensity to adopt integrated and PBL curricula. METHODS: National culture was defined by a country's scores on indexes for 4 dimensions of culture as described by Hofstede, defined as: power distance; individualism/collectivism; masculinity/femininity, and uncertainty avoidance. Non-integrated medical curricula were defined as those that included courses in 2 of the 3 basic sciences (anatomy, biochemistry and physiology) in the first 2 years; otherwise, by exclusion, curricula were assumed to be integrated. The medical curricula of 134 of the 263 schools in the 17 European countries included in Hofstede's study were examined. RESULTS: Correlations were calculated between the percentage of integrated medical curricula in a country and that country's scores on indexes for each of the 4 dimensions of culture. Significant negative correlations were found between the percentage of integrated curricula and scores on the power distance index (correlation coefficient [CC]: - 0.692; P = 0.002) and the uncertainty avoidance index (CC: - 0.704; P = 0.002). No significant correlations were found between the percentage of integrated curricula and scores on the indexes for individualism/collectivism and masculinity/femininity. CONCLUSIONS: A (medical) school which is considering adopting an integrated or PBL curriculum and which is based in a country with a high score on Hofstede's power distance index and/or uncertainty avoidance index must a priori design strategies to reduce or overcome the obstructive effects of these dimensions of culture on the school's organisation.
