Introduction: Current care is inadequate for patients with complicated multimorbidity, and frequently results in fragmented care. There is no widely agreed-upon optimal organisation of healthcare services for this patient group. By drawing upon existing literature and prior studies, we developed a patient-centred complex intervention for multimorbidity (CIM) and subsequently refined it into CIM version 2 (CIM2).

Background: Patients with multiple chronic conditions, for example, musculoskeletal conditions and comorbidities, often receive inadequate and sometimes even contradictory care. Physiotherapists are well qualified to manage patients with musculoskeletal conditions and comorbidities due to their education and experience with rehabilitation; however, it is unknown which challenges they face when treating these patients.

Aim: To identify challenges, treatment strategies, and delineations of areas of responsibility among physiotherapists working in private physiotherapy practice when treating people with musculoskeletal conditions and comorbidities.

Article Synopsis
  • The study examines the current management of low back pain (LBP) in Danish general practice, focusing on patients' self-management and clinicians' barriers to providing optimal care.
  • Data was collected from 71 clinicians and 294 patients over several months, highlighting patient demographics, treatment experiences, and consultation details.
  • Results show that while most clinicians felt they provided best practice care, barriers like time constraints and patient expectations impede their ability to do so effectively.

Introduction: Patients with complex multimorbidity face a high treatment burden and frequently have low quality of life. General practice is the key organisational setting in terms of offering people with complex multimorbidity integrated, longitudinal, patient-centred care. This protocol describes a pragmatic cluster randomised controlled trial to evaluate the effectiveness of an adaptive, multifaceted intervention in general practice for patients with complex multimorbidity.

Background: Type 2 diabetes (T2D) treatment has changed markedly within the last decades. We aimed to explore whether people with severe mental illness (SMI) have followed the same changes in T2D treatment as those without SMI, as multiple studies suggest that people with SMI receive suboptimal care for somatic disorders.

Methods: In this registry-based annual cohort study, we explored the T2D treatment from 2001 to 2015 provided in general practices of the Greater Copenhagen area.

Provision of integrated care is a challenge in patients with multimorbidity. Patients describe their pathway in the healthcare system as fragmented and important information is often not shared between sectors. The evidence regarding organisation of healthcare supporting patient-centered care in patients with multimorbidity is scarce.

It has been argued that persons with severe mental illness (SMI) receive poorer treatment for somatic comorbidities. This study assesses the treatment rates of glucose-lowering and cardiovascular medications among persons with incident type 2 diabetes (T2D) and SMI compared to persons with T2D without SMI. We identified persons ≥30 years old with incident diabetes (HbA1c ≥ 48 mmol/mol and/or glucose ≥ 11.

Background: People with multimorbidity, defined as the co-existence of two or more chronic conditions in an individual, often suffer from pain and functional limitations caused by musculoskeletal disorders and the chronic conditions. In chiropractic practice, two thirds of patients are treated for low back pain (LBP). It is unknown to what extent LBP is accompanied with chronic conditions in chiropractic practice.

Introduction: Polypharmacy is a common concern, especially in the older population. In some countries more that 50% of all individuals over 60 receive five or more drugs, most often due to multimorbidity and increased longevity. However, polypharmacy is associated with multiple adverse events, and more medication may not always be the answer.

Objectives: To categorize and examine the effectiveness regarding health-related quality of life (HRQoL), mental health, and mortality of care models for persons with multimorbidity in primary care, community care, and hospitals through a systematic review.

Methods: We searched PubMed, Embase, and Cochrane Central Register of Controlled Trials up to May 2020. One author screened titles and abstracts, and to validate, a second author screened 5% of the studies.

Background: Long-term preventive treatment such as treatment with statins should be reassessed among patients approaching end of life. The aim of the study was to describe the rate of discontinuation of statin treatment and factors associated with discontinuation in the 6 months before death.

Methods: This study is a retrospective cohort study using national registers and blood test results from primary health care patients.

Background: Lipid levels in blood have decreased considerably during the past decades in the general population partly due to use of statins. This study aims to investigate the trends in lipid levels between 2001 and 2018 in a statin-free population from primary health care, overall and by sex and age.

Methods: In a cohort of 634,119 patients from general practice with no diagnoses or medical treatments that affected lipid levels of total cholesterol (TC; n = 1,574,339) between 2001 and 2018 were identified.

Initiation of statin treatment is suggested to increase the international normalised ratio (INR) among warfarin users. However, available data is limited and conflicting. We conducted a register-based cohort study to evaluate the drug-drug interaction between warfarin and statins.

Objectives: To study a potential positive association (referred to as 'a match') between the need for health service (expressed by a mortality risk score) and observed health service utilisation among healthy Danish under-fives. Further, municipal differences in the match were examined to motivate focused comparisons between the organisation of regional health services.

Design: Register-based national cohort study.

Background: We investigated how four aspects of socio-demography influence the effectiveness of an intervention with structured personal diabetes care on long-term outcomes.

Methods: The Diabetes Care in General Practice (DCGP) study is a cluster-randomized trial involving a population-based sample of 1381 patients with newly diagnosed type 2-diabetes mellitus. We investigated how education, employment, cohabitation status and residence influenced the effectiveness of 6 years of intervention with structured personal diabetes care, resembling present day recommendations.

Aims: To investigate how self-reported risk factors (including socioeconomic status) predict undiagnosed, prevalent type 2 diabetes mellitus (T2DM). To externally validate Leicester Risk Assessment Score (LRAS), Finnish Diabetes Risk Score (FINDRISC) and Danish Diabetes Risk Score (DDRS), and to investigate how these predict a European Heart SCORE≥5% in a Danish population study.

Objective: To synthesize existing qualitative literature on patient-experienced burden of treatment in multimorbid patients.

Methods: A literature search identified available qualitative studies on the topic of burden of treatment in multimorbidity and meta-ethnography was applied as method. The authors' original findings were preserved, but also synthesized to new interpretations to investigate the concept of the burden of treatment using the Cumulative Complexity Model.
