Countries face challenges in maternal and newborn care (MNC) regarding costs, workforce and sustainability. Organising integrated care is increasingly seen as a way to address these challenges. The evidence on the optimal organisation of integrated MNC in order to improve outcomes is limited.

(1) To study associations between organisational elements of integrated care and maternal and neonatal health outcomes, experiences of women and professionals, healthcare costs and care processes and (2) to examine how the different dimensions of integrated care, as defined by the Rainbow Model of Integrated Care, are reflected in the literature addressing these organisational elements.

We included 288 papers and identified 23 organisational elements, grouped into 6 categories: personal continuity of care; interventions to improve interdisciplinary collaboration and coordination; care by a midwife; alternative payment models (non-fee-for-service); place of birth outside the obstetric unit and woman-centred care. Personal continuity, care by a midwife and births outside obstetric units were most consistently associated with improved maternal and newborn outcomes, positive experiences for women and professionals and potential cost savings, particularly where well-coordinated multidisciplinary care was established. Positive professional experiences of collaboration depended on clear roles, mutual trust and respectful interdisciplinary behaviour. Evidence on collaboration interventions and alternative payment models was inconclusive. Most studies emphasised clinical and professional aspects rather than organisational integration, with implementation barriers linked to prevailing biomedical system orientations.

Although the literature provides substantial evidence of organisational elements that contribute to improved outcomes, a significant gap remains in understanding how to overcome the barriers in sustainable implementation of these elements within healthcare systems. Interpreted through a systems and transition science lens, these findings suggest that strengthening integrated maternity care requires system-level changes aligning with WHO policy directions towards midwifery models of person-centred care.

The global prevalence of osteoarthritis (OA) is expected to rise as the population ages, leading to increased physical impairments that often reduce physical activity. Knee OA, in particular, is a leading cause of chronic pain and disability in people over 40. OA progression varies among individuals, with factors such as higher age and body mass index contributing to a more rapid progression. However, research suggests that engaging in physical activity such as hiking and running may help alleviate pain and slow OA progression. However, current literature on the relationship between physical activity and knee OA is largely retrospective, lacks comparative analyses across different physical activity types and rarely considers the intensity of physical activity. To address these gaps, the LoaD study was designed as a prospective cohort study aimed at examining how different physical activity types (ie, hiking, running, cycling and tennis) and their intensities relate to knee OA progression over 24 months in physically active individuals with early signs of the condition.

This prospective cohort study will include 300 participants (75 per physical activity group), who will be followed for 24 months. Eligible participants are aged 45–65, meet the National Institute for Health and Care Excellence (NICE) criteria for clinical knee OA and engage in a minimum weekly activity level for either running (60 min), cycling (120 min), playing tennis (60 min) or hiking (1 hike of 10 km). Baseline and follow-up assessments will include MRI, physical examination (eg, biometrics, lower extremity strength) and blood sampling for molecular biomarker assessment (eg, genetics, inflammatory biomarkers). Participants will receive monthly online questionnaires (eg, demographics, lifestyle, general health, history of knee injuries) and their physical activities will be tracked continuously by global positioning system data from wearable devices. The study’s primary outcomes focus on knee OA progression and symptom changes. These will be assessed through (1) structural progression of knee OA, measured using the MRI Osteoarthritis Knee Score (MOAKS) and (2) clinical symptom progression evaluated by (a) the Knee Injury and Osteoarthritis Outcome Score sport and recreation function subscale and (b) Visual Analogue Scale for pain during an activity nominated by the participant to be the most aggravating for knee pain in the past month (VASNA, 0–10). Differences between groups on the primary outcomes will be analysed using mixed-effects models to determine the impact of activity type and intensity on knee OA progression.

The study is approved by the Erasmus MC Medical Research and Ethics Committee (MREC) (MEC-2022-0420). The results of this study will be made publicly available through peer-reviewed international open-access scientific journals and national and international conferences. Participants will be informed about the results as soon as they are published.
