Show moreThe first aim of this thesis was to evaluate the Late Effects Comprehensive Care & Follow-up (LEEF) program after pediatric stem cell transplantation for nonmalignant diseases at the LUMC, and includes the assessment of various late effects and health-related quality of life. The second aim was to implement and evaluate aspects of VBHC at the LEEF program. This thesis describes lessons learned from the VBHC implementation in the Late Effects Comprehensive Care & Follow-up (LEEF) program and suggests possible future directions for VBHC implementation in similar comprehensive care programs. In this thesis, patient-reported outcomes (PROs) have demonstrated their value in research, such as long-term quality of life studies, but they have also proven to be valuable when used in clinical practice. The evaluation of PROs for both research purposes and clinical use can be expanded within the broader care path of pediatric stem cell transplantation. Furthermore, when discussing long-term HSCT outcomes, it is not solely about survival rates, but PROs are integral to capturing these long-term outcomes. Show less

Show moreObjectivesThis review addresses the common problem of missing patient-reported outcome (PRO) data in clinical trials by assessing the current practice of their statistical handling as reported in publications of randomized controlled trials (RCTs) in patients with breast cancer.Study Design and SettingWe searched PubMed to identify RCTs evaluating biomedical treatments in breast cancer patients with at least one PRO endpoint published between January 2019 and February 2022. Two reviewers independently assessed the eligibility of the publications for this scoping review and extracted prespecified information on missing PRO data and related statistical practices.ResultsOf 1,598 publications identified, 118 trials met the inclusion criteria. Eighty-eight (74.6%) trials reported the extent of missing data, with 11 (9.3%) not containing any missing PRO data. Twenty-one (19.6%) trials explicitly stated the statistical approach for handling missing data, with a preference for single imputation over multiple imputation approaches (57.2%/19.0%). Only six (5.6%) trials reported a sensitivity analysis to examine the extent to the results being affected by changes in assumptions made about missing PRO data.ConclusionInternational efforts to raise awareness of the importance of accurately reporting state-of-the-art handling of missing PRO data are not yet fully reflected in the current literature of breast cancer RCTs.

Show moreBackgroundThis study assesses the incidence of gastrointestinal symptoms in the first year after resection of esophageal or gastric cancer and its association with health-related quality of life (HRQoL), functioning, work productivity, and daily activities.Patients and MethodsPatients diagnosed with esophageal or gastric cancer between 2015 and 2021, who underwent a resection, and completed & GE; 2 questionnaires from the time intervals prior to resection and 0-3, 3-6, 6-9, and 9-12 months after resection were included. Multivariable generalized linear mixed models were used to assess changes in gastrointestinal symptoms over time and the impact of the number of gastrointestinal symptoms on HRQoL, functioning, work productivity, and daily activities for patients who underwent an esophagectomy or gastrectomy separately.ResultsThe study population consisted of 961 (78.8%) and 259 (21.2%) patients who underwent an esophagectomy and gastrectomy, respectively. For both groups, the majority of gastrointestinal symptoms changed significantly over time. Most clinically relevant differences were observed 0-3 after resection compared with prior to resection and included increased diarrhea, appetite loss, and eating restrictions, and specifically after esophagectomy dry mouth, trouble with coughing, and trouble talking. At 9-12 after resection one or more severe gastrointestinal symptoms were reported by 38.9% after esophagectomy and 33.7% after gastrectomy. A higher number of gastrointestinal symptoms was associated with poorer functioning, lower HRQoL, higher impairment in daily activities, and lower work productivity.ConclusionsThis study shows that gastrointestinal symptoms are frequently observed and burdensome after esophagectomy or gastrectomy, highlighting the importance to address these sequelae for high quality survivorship.

Show moreHealthcare is shifting towards a more person-centred approach, aiming at a personalised treatment that fits the patient’s preferences and needs. The use of patient-reported outcome measures (PROMs) to systematically assess outcomes such as health-related quality of life and symptom burden can facilitate the process of adapting to what is important to the patient. But, how to integrate PROMs into a routine care setting and how to use PROMs to achieve this personalised treatment? This dissertation provides insight into and practical knowledge of the implementation and use of PROMs in routine nephrology care. Research was performed within the different steps for implementation of PROMs into routine care, including the selection of PROMs, pilot testing PROMs, and nationwide implementation and use of PROMs, using a broad variety of quantitative and qualitative research methods. The use of PROMs was investigated both at individual patient level and at population level, with the potential to facilitate personalised treatment and evaluation of healthcare quality. Patients and healthcare professionals considered the PROM-results relevant additional information in routine practice, complementary to traditional clinical measures. In addition, discussing individual PROM results proved to be of great added value and directly applicable in routine care. Show less

Show moreSurvival rates in pediatric hematopoietic stem cell transplantation (HSCT) for nonmalignant diseases have improved due to advances in conditioning regimens, donor selection, and prophylaxis and treatment of infections and graft-versus-host disease. Insight into the long-term patient-reported outcomes (PROs) after pediatric HSCT for nonmalignant disease is lacking but essential for optimal shared decision making, counseling, and quality of care. The purpose of this research was to determine long-term patient-reported outcomes in allogeneic pediatric HSCT for nonmalignant diseases and to compare these results with Dutch reference data. This single-center cohort study evaluated PROs (PedsQL 4.0, PROMIS item banks), self- or proxy-reported, among patients at >= 2 years after pediatric allogeneic HSCT for nonmalignant disease. Mean scores were compared with those of the Dutch general population. Of 171 eligible patients, 119 participated, for a 70% response rate. The median patient age was 15.8 years (range, 2 to 49 years), and the median duration of follow-up was 8.7 years (range, 2 to 34 years). Indications for HSCT included inborn errors of immunity (n = 41), hemoglobinopathies (n = 37), and bone marrow failure (n = 41). Compared with reference data, significantly lower scores were found in adolescents (age 13 to 17 years) on the Total, Physical Health, and School Functioning PedsQL subscales. Significantly more Sleep Disturbance was reported in children (age 8 to 18 years). On the other hand, significantly better scores were seen on PROMIS Fatigue (age 5 to 7 years) and Pain Interference (age 8 to 18 years) and, in adults (age 19 to 30 years), on Depressive Symptoms and Sleep Disturbance. This study showed better or comparable very long-term PROs in patients after pediatric HSCT for nonmalignant diseases compared with the reference population. Children and adolescents seem to be the most affected, indicating the need for supportive care to prevent impaired quality of life and, more importantly, to amplify their long-term well-being.

Show moreThere are substantial disease and health-related quality-of-life (HRQoL) burdens for many patients with myasthenia gravis (MG), especially for those whose disease symptoms are not well controlled. HRQoL measures such as the Myasthenia Gravis Quality of Life 15-item revised (MG-QOL15r) and EuroQoL 5-Dimensions 5-Levels (EQ-5D-5L) are vital for evaluating the clinical benefit of therapeutic interventions in patients with MG, as they assess the burden of disease and the effectiveness of treatment, as perceived by patients. The phase 3 ADAPT study (NCT03669588) demonstrated that efgartigimod-a novel neonatal Fc receptor inhibitor-was well tolerated and that acetylcholine receptor antibody-positive (AChR-Ab+) participants who received efgartigimod had statistically significant improvements in MG-specific clinical scale scores. The ancillary data reported here, which cover an additional treatment cycle, show that these participants had similar significant improvements in HRQoL measures, the MG-QOL15r and EQ-5D-5L utility and visual analog scales, and that these improvements were maintained in the second treatment cycle. Positive effects on HRQoL were rapid, seen as early as the first week of treatment in both treatment cycles, and maintained for up to 4 weeks in the follow-up-only portion of treatment cycles. The pattern of improvements in HRQoL paralleled changes in immunoglobulin G level, and correlational analyses show that improvements were consistent across HRQoL measures and with clinical efficacy measures in the ADAPT study. The substantial and durable improvements in HRQoL end points in this study demonstrate the broader benefit of treatment with efgartigimod beyond relief of immediate signs and symptoms of gMG.

Show moreThis dissertation aimed to broaden our understanding of patient-relevant outcomes after kidney transplantation with a special focus on the patients’ perspectives. By conducting different studies in Dutch kidney transplant recipients and by synthesizing existing evidence, we explored several post-transplant patient-relevant outcomes (e.g. health-related quality of life, symptom burden, illness perceptions, medication non-adherence and hospital readmission) and investigated pathways to improve these outcomes, hereby adding to the existing body of knowledge in kidney transplantation. In Chapter 1, we briefly introduced the status quo of patient-relevant outcomes in kidney transplant recipients, discussed potential pathways to improve patient-relevant outcomes in kidney transplant recipients, and provided an overview of the studies presented in this dissertation. In Chapter 7, we provided a summary of our main findings from different studies described in Chapter 2 - 6, the clinical implication of our main findings, and suggestions for future research.

Show moreBackground: Reporting individual clinical and patient-reported outcomes to patients during consultations may add to patients' disease knowledge and activation and stimulate Shared Decision Making (SDM). These outcomes can be presented over time in a clear way by the means of dashboarding. We aimed to systematically develop a Chronic Kidney Disease (CKD) dashboard designed to support consultations, test its usability and explore conditions for optimal use in practice. Methods: For development a participatory approach with patients and healthcare professionals (HCPs) from three hospitals was used. Working groups and patient focus groups were conducted to identify needs and inform the dashboard's design. Usability was tested in patient interviews. A focus group with HCPs was held to identify conditions for optimal use of the dashboard in daily practice. Results: A dashboard was developed for CKD patients stage 3b-4 visualizing both clinical and patient-reported outcomes over time for use during consultations and accessible for patients at home. Both HCPs and patients indicated that the dashboard can: motivate patients in their treatment by providing feedback on outcomes over time; improve consultation conversations by enhanced preparation of both HCPs and patients; better inform patients, thereby facilitating shared decision making. HCPs and patients both stated that setting a topic agenda for the consultation together is important in effectively discussing the dashboard during consultations. Moreover, the dashboard should not dominate the conversation. Lastly, findings of the usability tests provided design requirements for optimal user-friendliness and clarity. Conclusions: Dashboarding can be a valuable way of reporting individual outcome information to patients and their clinicians as findings suggest it may stimulate patient activation and facilitate decision making. Co-creation with patients and HCPs was essential for successful development of the dashboard. Gained knowledge from the co-creation process can inform others wishing to develop similar digital tools for use in clinical practice. Show less

Show morePurpose Treatment with the tyrosine kinase inhibitor (TKI) imatinib in patients with gastrointestinal stromal tumours (GIST) causes symptoms that could negatively impact health-related quality of life (HRQoL). Treatment-related symptoms are usually clinician-reported and little is known about patient reports. We used survey and online patient forum data to investigate (1) prevalence of patient-reported symptoms; (2) coverage of symptoms mentioned on the forum by existing HRQoL questionnaires; and (3) priorities of prevalent symptoms in HRQoL assessment.Methods In the cross-sectional population-based survey study, Dutch GIST patients completed items from the EORTC QLQ-C30 and Symptom-Based Questionnaire (SBQ). In the forum study, machine learning algorithms were used to extract TKI side-effects from English messages on an international online forum for GIST patients. Prevalence of symptoms related to imatinib treatment in both sources was calculated and exploratively compared.Results Fatigue and muscle pain or cramps were reported most frequently. Seven out of 10 most reported symptoms (i.e. fatigue, muscle pain or cramps, facial swelling, joint pain, skin problems, diarrhoea, and oedema) overlapped between the two sources. Alopecia was frequently mentioned on the forum, but not in the survey. Four out of 10 most reported symptoms on the online forum are covered by the EORTC QLQ-C30. The EORTC-SBQ and EORTC Item Library cover 9 and 10 symptoms, respectively.Conclusion This first overview of patient-reported imatinib-related symptoms from two data sources helps to determine coverage of items in existing questionnaires, and prioritize HRQoL issues. Combining cancer-generic instruments with treatment-specific item lists will improve future HRQoL assessment in care and research in GIST patients using TKI. Show less

Show moreBackgroundIn 2019, more than 30% of all newly transplanted kidney transplant recipients in The Netherlands were above 65 years of age. Elderly patients are less prone to rejection, and death censored graft loss is less frequent compared to younger recipients. Elderly recipients do have increased rates of malignancy and infection-related mortality. Poor kidney transplant function in elderly recipients may be related to both pre-existing (i.e. donor-derived) kidney damage and increased susceptibility to nephrotoxicity of calcineurin inhibitors (CNIs) in kidneys from older donors. Hence, it is pivotal to shift the focus from prevention of rejection to preservation of graft function and prevention of over-immunosuppression in the elderly. The OPTIMIZE study will test the hypothesis that reduced CNI exposure in combination with everolimus will lead to better kidney transplant function, a reduced incidence of complications and improved health-related quality of life for kidney transplant recipients aged 65 years and older, compared to standard immunosuppression.MethodsThis open label, randomized, multicenter clinical trial will include 374 elderly kidney transplant recipients (>= 65 years) and consists of two strata. Stratum A includes elderly recipients of a kidney from an elderly deceased donor and stratum B includes elderly recipients of a kidney from a living donor or from a deceased donor<65 years. In each stratum, subjects will be randomized to a standard, tacrolimus-based immunosuppressive regimen with mycophenolate mofetil and glucocorticoids or an adapted immunosuppressive regimen with reduced CNI exposure in combination with everolimus and glucocorticoids. The primary endpoint is 'successful transplantation', defined as survival with a functioning graft and an eGFR30 ml/min per 1.73 m(2) in stratum A and >= 45 ml/min per 1.73 m(2) in stratum B, after 2 years, respectively.ConclusionsThe OPTIMIZE study will help to determine the optimal immunosuppressive regimen after kidney transplantation for elderly patients and the cost-effectiveness of this regimen. It will also provide deeper insight into immunosenescence and both subjective and objective outcomes after kidney transplantation in elderly recipients.Trial registrationClinicalTrials.gov: NCT03797196, registered January 9th, 2019.

Show moreBackground: In the EORTC 1410/ INTELLANCE 2 randomised, phase II study (NCT02343406), with the antibody-edrug conjugate depatuxizumab mafodotin (Depatux-M, ABT-414) in patients with recurrent EGFR-amplified glioblastoma, the primary end-point (overall survival) was not met, and the drug had ocular dose-limiting toxicity. This study reports results from the prespecified health-related quality of life (HRQoL) and neurological deterioration-free survival (NDFS) exploratory analysis.Patients and methods: Patients (n Z 260) were randomised 1:1:1 to receive either Depatux-M 1.25 mg/kg or 1.0 mg/kg intravenously every 2 weeks with oral temozolomide (TMZ) 150 mg/ m(2), Depatux-M alone, or TMZ or oral lomustine (CCNU) 110 mg/ m(2) ( TMZ/CCNU). HRQoL outcomes were recorded using the EORTC core Quality of Life QLQ-C30, and brain cancer-specific QLQ-BN20 questionnaires. Questionnaires were completed at baseline, weeks 8 and 16, and month 6, and changes from baseline to each time point were calculated. NDFS was defined as time to first deterioration in World Health Organisation performance status.Results: Compliance with HRQoL was 88.1% at baseline and decreased to 37.9% at month 6. Differences from baseline between Depatux-M arms and TMZ/CCNU in global health/QoL status throughout treatment did not reach clinical relevance (>= 10 points). Self-reported visual disorders deteriorated to a clinically relevant extent with Depatux-M arms versus TMZ/CCNU at all timepoints (mean differences range: 24.6-35.1 points). Changes from baseline for other HRQoL scales and NDFS were generally similar between treatment arms.Conclusions: Depatux-M had no impact on HRQoL and NDFS in patients with EGFRamplified recurrent glioblastoma, except for more visual disorders, an expected side- effect of the study drug.

Show morePurpose Results of patient-reported outcome measures (PROMs) are increasingly used to inform healthcare decision-making. Research has shown that response shift can impact PROM results. As part of an international collaboration, our goal is to provide a framework regarding the implications of response shift at the level of patient care (micro), healthcare institute (meso), and healthcare policy (macro). Methods Empirical evidence of response shift that can influence patients' self-reported health and preferences provided the foundation for development of the framework. Measurement validity theory, hermeneutic philosophy, and micro-, meso-, and macro-level healthcare decision-making informed our theoretical analysis. Results At the micro-level, patients' self-reported health needs to be interpreted via dialogue with the clinician to avoid misinterpretation of PROM data due to response shift. It is also important to consider the potential impact of response shift on study results, when these are used to support decisions. At the meso-level, individual-level data should be examined for response shift before aggregating PROM data for decision-making related to quality improvement, performance monitoring, and accreditation. At the macro-level, critical reflection on the conceptualization of health is required to know whether response shift needs to be controlled for when PROM data are used to inform healthcare coverage. Conclusion Given empirical evidence of response shift, there is a critical need for guidelines and knowledge translation to avoid potential misinterpretations of PROM results and consequential biases in decision-making. Our framework with guiding questions provides a structure for developing strategies to address potential impacts of response shift at micro-, meso-, and macro-levels. Show less

Show moreObjectives: Physical activity is promoted in patients with hip or knee osteoarthritis (OA), yet little is known about its relationship with symptoms, functional limitations and Quality of Life (QoL). We investigated if OA-associated pain, functional limitations and QoL are associated with objectively measured physical activity in patients with end-stage hip/knee OA.Methods: Cross-sectional study including patients scheduled for primary total hip/knee arthroplasty. Patients wore an accelerometer (Activ8) with physical activity assessed over waking hours, and expressed as number of activity daily counts (ADC) per hour, %time spent on physical activity i.e. walking, cycling or running (%PA), and %time spent sedentary (%SB). Pain, functional limitations and joint-specific and general QoL were assessed with the Hip disability/Knee Injury and Osteoarthritis Outcome Score (HOOS/KOOS) and the Short Form (SF)-12. Multivariate linear regression models with the three to Z-scores transformed parameters of physical activity as dependent variables and adjusted for confounding, were conducted. Results: 49 hip and 48 knee OA patients were included. In hip and knee OA patients the mean number of ADC, %PA and %SB were 18.79 +/- 7.25 and 21.19 +/- 6.16, 14 +/- 6.4 and 15 +/- 5.0, and 66 +/- 10.5 and 68 +/- 8.7, respectively. In hip OA, better joint-specific and general QoL were associated with more ADC, (13 0.028; 95%CI:0.007-0.048, 130.041; 95%CI:0.010- 0.071). Also, better general QoL was associated with the %PA (13 0.040, 95%CI:0.007- 0.073). No other associations were found.Conclusion: Whereas QoL was associated with physical activity in hip OA, pain and functional limitations were not related to objectively measured physical activity in patients with end-stage hip or knee OA.(c) 2021 The Authors.

Show moreBackground and purpose: A matched comparison of external beam radiotherapy (EBRT) versus brachytherapy recently demonstrated that EBRT appears at least as effective for palliating dysphagia in patients with incurable esophageal cancer. The aim of this analysis was to compare patient-reported outcomes (PROs) after EBRT versus brachytherapy.Materials and methods: In a multicenter prospective cohort study, patients with incurable esophageal cancer requiring palliation of dysphagia were included to undergo EBRT (20 Gy in 5 fractions). This EBRT cohort was compared to the single-dose 12 Gy brachytherapy cohort of the previously reported SIRECtrial. Propensity score matching was applied to adjust for baseline imbalances. The primary endpoint of dysphagia improvement was reported previously. PROs were secondary outcomes and assessed at baseline and 3 months after treatment using EORTC QLQ-C30 and QLQ-OES18 questionnaires.Results: A total of 115 enrolled EBRT patients and 93 brachytherapy patients were eligible. After matching, 69 well-balanced pairs remained. At follow-up, significant deteriorations in functioning (i.e. physical, role, social), pain, appetite loss, and trouble with taste were observed after brachytherapy. In the EBRT group, such deterioration was observed only for role functioning, while significant improvements in trouble with eating and pain were found. Between-group comparison showed mostly comparable PRO changes, but significantly favored EBRT with regard to nausea, vomiting, pain, and appetite loss.Conclusion: Short course EBRT results in similar or better PROs at 3 months after treatment compared to single-dose brachytherapy for the palliation of malignant dysphagia. These findings further support its use and inclusion in clinical practice guidelines. (C) 2020 The Author(s). Published by Elsevier B.V. Show less

Show moreOver a century ago, the systematic evaluation of medical treatment outcomes was first described by Ernest Codman. At that time a too progressive thought, while the value of measuring the quality of care is seen nowadays.The NABON Breast Cancer Audit (NBCA) provides insight into the various care processes that are part of the complex multidisciplinary treatment of patients diagnosed with breast cancer. Results of the NBCA show a good and still improving quality of care for patients diagnosed with breast cancer. In addition, this thesis provides insight into a sub-area where variation between hospitals is found; the performance of an immediate breast reconstruction in patients undergoing mastectomy. Many factors influence this hospital variation, such as patient and tumour factors, hospital factors and differences in indications for immediate breast reconstruction between surgeons and plastic surgeons. Physicians should inform patients about the various breast cancer treatment options. Informing a patient about immediate breast reconstruction results in a 14 times higher chance of actually undergoing a breast reconstruction after mastectomy.These factors should to be evaluated and improved as quality of life is higher for patients with immediate breast reconstruction than with mastectomy alone. By continuously measuring, providing feedback and acting on the data found at both a national level and in the consultation room, Ernest Codman's heritage will certainly be realized. Show less

Show moreObjectives Rheumatoid arthritis (RA) patients show an earlier circadian rhythm (i.e. serum melatonin peaks earlier during the night, indicating an earlier timing of the internal circadian pacemaker). In the current study, we examined whether the chronotype, which is influenced by the circadian rhythm, is also earlier. In addition, we explored whether chronotype is related to disease activity and patient-reported outcomes.Methods The chronotype (Munich Chronotype Questionnaire) of patients with RA (n = 121; mean age 60 years, 73% female) was compared with that of subjects from the general population (norm group; n = 1695) with a one-sample t test. In addition, we investigated chronotype in relation to disease activity (Disease Activity Score; DAS), reported morning stiffness, fatigue (Checklist Individual Strength), and health-related quality of life (RAND-36).Results The chronotype of patients with RA was, on average, 23 min (95% CI, 15 to 31 min) earlier than that of the norm group (t(115) = - 5.901, p < 0.001, d = 0.55). Chronotype was not related to disease activity or patient-reported outcomes (p > 0.05).Conclusion As expected, chronotype was earlier in RA patients. However, in this correlational study, chronotype was not related to disease activity or patient-reported outcomes. An experimental study is needed to examine whether delaying the circadian rhythm has a positive influence on these outcomes. This insight could improve our understanding of the pathophysiology of RA and contribute to exploring new treatment possibilities.Key Points This is the first study examining chronotype in patients with rheumatoid arthritis, and how chronotype relates to disease activity and patient-reported outcomes.We found an earlier chronotype in patients with rheumatoid arthritis than in subjects from the general population.In this correlational study, chronotype was not related to disease activity or patient-reported outcomes. An experimental study is needed to examine whether delaying the circadian rhythm positively influences these outcomes. Show less

Show moreIntroduction: Several factors are included in decision making for treatment of patients with locally advanced rectal cancer, including a trade-off between risks and gains of both clinical and functional outcomes. However, it is largely unknown which outcomes are most important to patients and whether this differs between patients and clinicians.Methods: Both clinicians and patients treated for locally advanced rectal cancer were invited to fill out an online questionnaire, including a choice-based conjoint experiment. Participants were presented 14 comparisons of two hypothetical case presentations, characterized by different treatments and outcomes of care (6 attributes) and were asked to select the case with the best outcome at that moment. Hierarchical Bayes Estimation was used to calculate the relative importance (RI) of each of the six attributes.Results: In total, 94 patients and 128 clinicians completed the questionnaire. For patients, avoiding surgery with permanent stoma was most important (RI 24.4, 95%CI 21.88-26.87) and a 2-year difference in disease-free survival was least important (RI 5.6, 95%CI 4.9-6.2). Clinicians assigned highest importance to avoiding severe and daily worries about cancer recurrence (RI 30.7, 95%CI 29.1-32.4), while this was ranked 4th by patients (RI 17.9, 95%CI 16.5-19.4, p < 0.001).Conclusion: When confronted with different outcomes within one case description, patients find the duration of disease free survival the least important. In addition, considerable differences were found between the importance assigned by patients and clinicians to clinical and functional outcomes, most notably in avoiding surgery with permanent stoma and worries about recurrence.

Show moreObjective: The International Consortium for Health Outcomes Measurement developed the Pregnancy and Childbirth (PCB) outcome set to improve value-based perinatal care. This set contains clinician-reported outcomes and patient-reported outcomes. We validated the set for use in the Netherlands by exploring its applicability among all end-users prior to implementation.Methods: A mixed-methods design was applied. A survey was performed to assess patients (n = 142), professionals (n = 134) and administrators (n = 35) views on the PCB set. To further explore applicability, separate focus groups were held with representatives of each of these groups.Results: The majority of survey participants agreed that the PCB set contains the most important outcomes. Patient-reported experience measures were considered relevant by the majority of participants. Perceived relevance of patient-reported outcome measures varied. Main themes from the focus groups were content of the set, data collection timing, implementation (also IT and transparency), and quality-based governance.Conclusion: This study supports suitability of the PCB outcome set for implementation, evaluation of quality of care and shared decision making in perinatal care.Practice Implications: Implementation of the PCB set may change existing care pathways of perinatal care. Focus on transparency of outcomes is required in order to achieve quality-based governance with proper IT solutions. (C) 2019 The Authors. Published by Elsevier B.V. Show less
