The evaluation of the introduction of a quality management system: A process-oriented case study in a large rehabilitation hospital

Willem H. van Harten; Ton F. Casparie; O.A.M. Fisscher

OBJECTIVES So far, there is limited proof concerning the effects of the introduction of quality management systems (QMS) on organisational level. This study concerns the introduction of a QMS in a large rehabilitation hospital. METHODS Using an observational framework, a process-analysis is performed. The effects were analysed with repeated analyses using the Dutch version of the EFQM-model. RESULTS The introduction of a QMS can be seen as a change process; the pre-change diagnosis proved to be essential. Although many change-related aspects are vital, training and communication, in particular, seemed to be underestimated. Outcomes are a positive correlation between participation in quality activities and work satisfaction and a repeatedly favourable EFQM-score (compared to national levels). CONCLUSIONS Through a process-analysis, information could be generated to guide organisations in introducing a QMS. An outcome analysis revealed positive effects both in the EFQM-score and the staffs work satisfaction.

earlier checkpoint inhibitor protocols. Patients with metastatic melanoma and HIV on highly active antiretroviral therapy have reportedly tolerated immunotherapy well, with no apparent eff ects on HIV disease activity serologically and no adverse pharmacokinetic interactions with highly active antiretroviral therapy. 7,8 Ravi and colleagues described the use of immunotherapy in nine patients with hepatitis B and C with advanced melanoma; although viral loads fl uctuated in some patients during therapy, this had no apparent clinical signifi cance. 9 It must be emphasised that these anecdotal reports cannot be applied broadly in clinical practice. However, these scenarios highlight the need to examine whether or not evidence exists to suggest that patients with particular comorbidities will be harmed by new treatments. If not, consideration can be given to allowing enrollment of these patients on protocol or in a separate cohort so that we can understand how best to treat them in the offi ce. In summary, overly restrictive eligibility criteria hinder accrual and jeopardise the generalisability and usefulness of study results in the broader population. Furthermore, the assessment of therapeutic eff ects on comorbid diseases in clinical trials is often the safest setting in which to capture data, compared with a postmarketing experience in which data are often not well recorded or disseminated. 3 We acknowledge that one must balance the need for diverse accrual with the need for broad eligibility criteria. 10

Methodological considerations on the assessment of the implementation of quality management systems

Willem H. van Harten; Ton F. Casparie; O.A.M. Fisscher

Quality management systems (QMS) can be considered as an emerging management technology in health care. It is as yet not common to perform assessment of such technology in order to obtain relevant information on the added value. In this paper the specific aspects of the assessment of a quality management system are explored and various designs are presented. Based on the experiences of performing an evaluation of a QMS in a rehabilitation hospital an improved design for an evaluation study is presented.

Only between 25% and 50% of patients invited to participate in clinical trial‐based physical exercise programs during cancer treatment agree to do so. The purpose of this study was to identify factors associated significantly with the decision (not) to participate in a randomized controlled trial of physical exercise during adjuvant chemotherapy for breast cancer.

BACKGROUND Translational research is a complex cumulative process that takes time. However, the operating environment for cancer centers engaged in translational research is now financially insecure. Centers are challenged to improve results and reduce time from discovery to practice innovations. Performance assessment can identify improvement areas that will help reduce translational delays. Currently, no standard method exists to identify models for use in performance assessment. This study aimed to critically appraise translational research models for suitability in performance assessment of cancer centers. METHODS We conducted a systematic review to identify models and developed a set of criteria based on scientometrics, complex adaptive systems, research and development processes, and strategic evaluation. Models were assessed for linkage between research and care components, new knowledge, systems integration, performance assessment, and review of other models. RESULTS Twelve models were identified; six described phases/components for translational research in different blocks (T models) and six described the process of translational research (process models). Both models view translational research as an accumulation of new knowledge. However, process models more clearly address systems integration, link research and care components, and were developed for evaluating and improving the performance of translational research. T models are more likely to review other models. CONCLUSION Process models seem to be more suitable for performance assessment of cancer centers than T models. The most suitable process models (the Process Marker Model and Lean and Six Sigma applications) must be thoroughly tested in practice.

PurposePortals are increasingly used to improve patient empowerment, but are still uncommon in oncology. In this study, we explored cancer survivors’ and health professionals’ expectations of possible features of an interactive portal.MethodsWe conducted three focus groups with breast cancer survivors (n = 21), two with lung cancer survivors (n = 14), and four with health professionals (n = 31). Drafts of possible features of an interactive portal were presented as static screenshots: survivorship care plan (SCP), access to electronic medical record (EMR), appointments, e-consultation, online patient community, patient reported outcomes (PROs) plus feedback, telemonitoring service, online rehabilitation program, and online psychosocial self-management program. This presentation was followed by an open discussion. Focus groups were audiotaped, transcribed verbatim, and data were analyzed using content analysis.ResultsImportant themes included fulfillment of information needs, communication, motivation, quality of feedback, and supervision. Cancer survivors were primarily interested in features that could fulfill their information needs: SCP, access to their EMR, and an overview of appointments. Health professionals considered PROs and telemonitoring as most useful features, as these provide relevant information about survivors’ health status. We recommend to minimally include these features in an interactive portal for cancer survivors.ConclusionsThis is the first study that evaluated the expectations of cancer survivors and health professionals concerning an interactive portal. Both groups were positive about the introduction of such a portal, although their preferences for the various features differed. These findings reflect their unique perspective and emphasize the importance of involving multiple stakeholders in the actual design process.

PURPOSE In order to improve the quality of care in Cancer Centers (CC) and designate Comprehensive Cancer Centers (CCCs), the Organization for European Cancer Institutes (OECI) launched an Accreditation and Designation (A&D) program. The program facilitates the collection of defined data and the assessment of cancer center quality. This study analyzes the results of the first 10 European centers that entered the program. METHODS The assessment included 927 items divided across qualitative and quantitative questionnaires. Data collected during self-assessment and peer-review from the 10 first participating centers were combined in a database for comparative analysis using simple statistics. Quantitative and qualitative results were validated by auditors during the peer review visits. RESULTS Volumes of various functions and activities dedicated to care, research, and education varied widely among centers. There were no significant differences in resources for radiology, radiotherapy, pathologic diagnostic, and surgery. Differences were observed in the use of clinical pathways but not for the practices of holding multidisciplinary team meetings and conforming to guidelines. Regarding human resources, main differences were in the composition and number of supportive care and research staff. All 10 centers applied as CCCs; five obtained the label, and five were designated as CCs. CONCLUSION The OECI A&D program allows comparisons between centers with regard to management, research, care, education, and designation as CCs or CCCs. Through the peer review system, recommendations for improvements are given. Assessing the added value of the program, as well as research and patient treatment outcomes, is the next step.

BackgroundThe delivery of radiotherapy (RT) involves the use of rather expensive resources and multi-disciplinary staff. As the number of cancer patients receiving RT increases, timely delivery becomes increasingly difficult due to the complexities related to, among others, variable patient inflow, complex patient routing, and the joint planning of multiple resources. Operations research (OR) methods have been successfully applied to solve many logistics problems through the development of advanced analytical models for improved decision making. This paper presents the state of the art in the application of OR methods for logistics optimization in RT, at various managerial levels.MethodsA literature search was performed in six databases covering several disciplines, from the medical to the technical field. Papers included in the review were published in peer-reviewed journals from 2000 to 2015. Data extraction includes the subject of research, the OR methods used in the study, the extent of implementation according to a six-stage model and the (potential) impact of the results in practice.ResultsFrom the 33 papers included in the review, 18 addressed problems related to patient scheduling (of which 12 focus on scheduling patients on linear accelerators), 8 focus on strategic decision making, 5 on resource capacity planning, and 2 on patient prioritization. Although calculating promising results, none of the papers reported a full implementation of the model with at least a thorough pre-post performance evaluation, indicating that, apart from possible reporting bias, implementation rates of OR models in RT are probably low.ConclusionsThe literature on OR applications in RT covers a wide range of approaches from strategic capacity management to operational scheduling levels, and shows that considerable benefits in terms of both waiting times and resource utilization are likely to be achieved. Various fields can be further developed, for instance optimizing the coordination between the available capacity of different imaging devices or developing scheduling models that consider the RT chain of operations as a whole rather than the treatment machines alone.

Even though the increasing incidence of cancer is mainly a consequence of a population with a longer life span, part of this augmentation is related to the increasing prevalence of patients living with a chronic cancer disease. To fight the problem, improved preventive strategies are mandatory in combination with an innovative health care provision that is driven by research. To overcome the weakness of translational research the OECI is proposing a practical approach as part of a strategy foreseen by the EUROCAN+PLUS feasibility study, which was launched by the EC in order to identify mechanisms for the coordination of cancer research in Europe.

Objectives To support return to work (RTW) among cancer patients, a multidisciplinary rehabilitation programme was developed which combined occupational counselling with a supervised physical exercise programme during chemotherapy. The aim was to investigate RTW rates of cancer patients and to evaluate changes in work-related quality of life and physical outcomes. Design Longitudinal prospective intervention study using a one-group design. Setting Two hospitals in the Netherlands. Participants Of the eligible patients, 56% participated; 93 patients with a primary diagnosis of cancer receiving chemotherapy and on sick leave were included. Patients completed questionnaires on RTW, the importance of work, work ability (WAI), RTW self-efficacy, fatigue (MFI), and quality of life (EORTC QLQ C-30) at baseline and 6, 12 and 18 months follow-up. Before and after the exercise programme 1-repetition maximum (1RM) muscle strength and cardiorespiratory fitness (VO2 peak) were assessed. Results Six months after the start of a multidisciplinary rehabilitation programme that combined occupational counselling with a supervised physical exercise programme, 59% of the cancer patients returned to work, 86% at 12 months and 83% at 18 months. In addition, significant improvements (p<0.05) in the importance of work, work ability, RTW self-efficacy, and quality of life were observed, whereas fatigue levels were significantly reduced. After completing the exercise programme, 1RM muscle strength was significantly increased but there was no improvement in VO2 peak level. Conclusions RTW rates of cancer patients were high after completion of the multidisciplinary rehabilitation programme. A multidisciplinary rehabilitation programme which combines occupational counselling with a supervised physical exercise programme is likely to result in RTW, reduced fatigue and increased importance of work, work ability, and quality of life.
