Between a rock and a hard place: balancing roles of clinician and co-researcher in a primary health care setting - A qualitative study
Background: The participation of clinicians in clinical research is necessary, but balancing research and clinical duties can be challenging. We explored chiropractors’ experiences of participating in a clinical trial on spinal manipulation of the neck in primary health care (PHC). Methods: A qualitative design was adopted, underpinned by social interactionism. Five virtual focus group interviews were performed between August-November 2023, including 15 chiropractors, who were involved in a clinical trial in PHC. Thematic analysis was applied. Results: The interviewees were motivated to participate in the clinical trial to contribute to professional development through investigating the use of spinal manipulation. However, patient recruitment and adherence to the treatment protocol were more difficult than anticipated, especially when patients realised that the treatment would be determined by randomisation and because the chiropractors had to deliver the sham/placebo interventions. The interviewed chiropractors continually negotiated conflicting obligations of clinicians, co-researchers, and breadwinners, shifting loyalties between these roles in response to situational demands. Conclusions: The clinicians’ motivations to take part in the trial varied but were in general rooted in a wish to contribute to strengthening the chiropractic profession. The negotiation of multiple roles and shifting loyalties rendered them moral agents. Our findings illustrate the social and relational nature of participating as a co-researcher in a trial conducted in a chiropractic PHC context. Our study also highlights a need for better support systems for research in PHC. This calls for political and organisational will to establish systems that provide necessary support to researchers and clinical co-researchers.

Patient Work in Long-Term Conditions
Long-term conditions are one of the major causes to morbidity and death worldwide. Management of such conditions in healthcare settings has been framed as a challenge for healthcare systems, and people living with long-term conditions often experience fragmented care. Integrated care approaches have been advocated as the solution, but few studies include the work done by patients and its significance for care processes. The present study aimed to explore the work of people with long-term conditions in the unfolding of their care trajectories. The study is based on semi-structured interviews of people living with chronic obstructive pulmonary disease and musculoskeletal disorders. The participants were all home-dwelling and living in Norway. Reflexive thematic analysis was used to guide the analysis. Theory about work as theorized by Strauss et al. was central to the analysis. The persons highlight that they feel that it is up to them to ask questions and initiate care, that they monitor their bodies to be equipped to act adequately when changes occur, and that they engage in deliberative interaction with healthcare personnel. The findings add depth to current knowledge and highlight that people living with long-term conditions participate in the unfolding of their care trajectories by doing comprehensive work. Framing what people with long-term conditions do when participating in their care trajectories as work brings forth aspects of healthcare use that may be less visible for healthcare personnel and enables addressing individual care trajectories as intertwined with patient work.

The in- and outpatient health care use of patients with COPD before and after initiation of home care: a registry study from Norway
Chronic obstructive pulmonary disease (COPD) is a common condition associated with age, multimorbidity and frequently involves the use of health care across levels. Understanding the factors associated with the initiation of long-term care is important when planning the future need for services. We describe healthcare use before and after the reception of any home care. We further studied the associations between healthcare use and first registered home care service and from first registered home care service to nursing home admission or death. Patients residing in Oslo or Trondheim at the time of first contact with a COPD primary diagnosis, 2009-2018. Patient data were linked across national and municipal registries, covering healthcare and sociodemographics. The sample consisted of 16,738 individuals. There was a marked increase in inpatient and outpatient hospital contacts in the years prior to and after the reception of any home care. Adjusted for comorbidities and sociodemographics, high numbers of GP consultations, and inpatient and outpatient hospital contacts for respiratory diagnoses were associated with a significantly higher likelihood of receiving home care the next year (hazard odds ratios > 1.3). Following the reception of home care, the type of home care service received (e.g. home nursing or short-term rehabilitation/treatment) was more important than outpatient services in predicting next-year nursing home admission or death. Including data on prior outpatient care when predicting future need for home care is beneficial. A high frequency (top 10%) of yearly GP, in- or outpatient hospital contacts can imply that the patient may be in need of home care in the near future.

Post-exertional malaise in daily life and experimental exercise models in patients with myalgic encephalomyelitis/chronic fatigue syndrome
Post-exertional malaise (PEM) is commonly recognized as a hallmark of myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) and is often used as one of several criteria for diagnosing ME/CFS. In this perspective paper we want to reflect on how PEM is understood, assessed, and evaluated in scientific literature, and to identify topics to be addressed in future research. Studies show that patients use a wide variety of words and concepts to label their experience of PEM in everyday life, and they report physical or mental exertions as triggers of PEM. They also report that PEM may have an immediate or delayed onset and may last from a few days to several months. When standardized exercise tests are used to trigger PEM experimentally, the exacerbation of symptoms has a more immediate onset but still shows a wide variability in duration. There are indications of altered muscular metabolism and autonomic nervous responses if exercise is repeated on successive days in patients with ME/CFS. The decreased muscular capacity appears to be maintained over several days following such controlled exercise bouts. These responses may correspond to patients’ experiences of increased exertion. Based on this background we argue that there is a need to look more closely into the processes occurring in the restitution period following exercise, as PEM reaches the peak in this phase.

Cross-Cultural Contact and Norwegian Language Skills Among Ethnic Minority Women in Norway, and Relationship with Physical Activity in Pregnancy and Postpartum: The STORK-Groruddalen Cohort Study
There are few studies of the migration context factors and physical activity (PA) level among minority ethnic women in Europe. We investigated the association between migration context factors and moderate to vigorous physical activity (MVPA) among minority ethnic women. Objectively recorded MVPA were obtained from 487 minority ethnic women included in the STORK-Groruddalen Cohort Study at three time points in pregnancy/postpartum. We investigated the associations between (a) contact with ethnic Norwegians and (b) Norwegian language skills and. No associations were observed in pregnancy. Postpartum, women who reported contact with ethnic Norwegians accumulated 17 MVPA min/day (95% CI: -.60, 34.54) more than women with no contact. In complete case analyses, this difference was significant (27 MVPA min/day (95% CI: 8.60, 44.54)). In early postpartum women with contact with ethnic Norwegians seems to be more physically active than women without contact. No associations were observed in pregnancy.

Associations between social support and physical activity in postpartum: a Norwegian multi-ethnic cohort study
Background: Social support is associated with higher self-reported physical activity (PA) in postpartum women, but it is unknown if similar association occur when using objective PA data. The aim was to explore the associations between social support and objectively recorded moderate-to-vigorous physical activity (MVPA) postpartum, and if associations differed across ethnic groups. Methods: We used data from 636 women who participated in the STORK Groruddalen cohort study (2008–2010). MVPA minutes/day in bouts of ≥ 10 minutes was recorded by SenseWear Armband™ Pro3 (SWA) over 7 days, 14 weeks postpartum. Social support for PA from family or friends was measured by a modified 12-item version of the Social Support for Exercise Scale. We used single items, family support mean score (6 items) and friends’ support mean score (6-items) in four separate count models, and adjusted for SWA week, age, ethnicity, education, parity, body mass index and time since birth. We tested interactions between social support and ethnicity. Analyses were performed on complete cases and imputed data. Results: Based on imputed data, we observed that women who reported low and high support from family accumulated 16.2 (IQR: 6.1–39.1) and 18.6 (IQR: 5.0-46.5) MVPA minutes/day, respectively. Women who reported low and high support from friends accumulated 18.7 (IQR: 5.9–43.6) and 16.8 (IQR: 5.0-45.8) MVPA minutes/day. We observed a 12% increase in MVPA minutes/day for each additional increase in mean family support score (IRR = 1.12, 95% CI: 1.02 to 1.25). Women reporting high level of support from family on ‘discuss PA’, ‘co-participation’ and ‘take over chores’ accumulated 33%, 37% and 25% more MVPA minutes/day than women reporting low level of support respectively (‘discuss PA’: IRR = 1.33, 95% CI: 1.03 to 1.72, ‘co-participation’: IRR = 1.37, 95% CI: 1.13 to 1.66 and ‘take over chores’: IRR = 1.25, 95% CI: 1.02 to 1.54). Associations were not modified by ethnicity. No statistically significant association between support from friends and MVPA was observed. Similar results were found in complete case analyses, with a few exceptions. Conclusion: Overall family support and specific forms of support from family were associated with MVPA across ethnic groups, while support from friends was not associated with MVPA postpartum.
