Without a diagnosis, the right therapy often cannot be carried out and without the right therapy, the patients are denied the opportunity for a cure or relief from their symptoms. In addition, rare diseases can also have economic consequences for those affected.

Introduction: Outpatient and inpatient hospice and palliative care services have been significantly expanded in Germany in recent decades and are increasingly being supplemented by day care services. However, the availability of these services varies greatly from region to region. The extent to which the availability of these care structures is matched by a regional need based on local population structures is as yet unknown.

Background: Individuals of working age spend a significant amount of time at the workplace making it an important context for disease prevention and management. The temporal development and prevalence of T2D have been shown to differ in the working population based on gender, age group and occupational sector regardless of socioeconomic status. Given potential differences in risk factors associated with different work environments, this study aims to define vulnerable occupational groups by examining T2D severity and its trends in working men and women with T2D of two age groups and among nine occupational sectors.

Background: Socioeconomic inequalities in type 2 diabetes (T2D) are well established in the literature. However, within the background of changing work contexts associated with digitalization and its effect on lifestyle and sedentary behavior, little is known on T2D prevalence and trends among different occupational groups. This study aims to examine occupational sector differences in T2D prevalence and trends thereof between 2012 and 2019.

The objective of universal health care systems is to achieve equality in the use of health services at the same level of care need. This study evaluates the relationship of socioeconomic position with the frequency of doctor visits in subjects with and without chronic diseases in Germany and Spain. The dependent variables included number of consultations and if a medical consultation occurred.

Chronic obstructive pulmonary disease (COPD) is associated with smoking and work-related health hazards. Most studies have reported prevalences, and the number of studies examining incidences and social inequalities is small. We analyzed the development of social inequalities of COPD-incidences in terms of income and exacerbations in terms of hospital admissions.

Background: Ventricular assist device (VAD) implantation has become an alternative treatment for patients with end-stage heart failure. In Germany, valid and reliable instruments to assess health-related quality of life in patients with VAD are lacking.

Objective: The aim of this study was to present the psychometric validation of the German version of the Quality of Life with a Ventricular Assist Device questionnaire.

Background: There is a steady increase in diabetes prevalence globally and many studies imply that high socioeconomic status (SES) is inversely related to diabetes prevalence. However, there is scarcity in literature from countries like Egypt regarding this topic.

Methods: This study aims to investigate prevalence of diabetes in Egypt between 2008 and 2015, and the effect of SES.

While socioeconomic inequalities in the prevalence and management of type 2 diabetes (T2D) are well established, little is known about whether inequalities exist in the prevalence and the temporal development of T2D comorbidities. Previous research points towards expansion of morbidity in T2D as depicted mainly by a rising trend of T2D comorbidities. Against this background, and using German claims data, this study aims to examine whether socioeconomic status (SES) inequalities exist in the rates and the temporal development of T2D comorbidities.

Background: Extending the number of active working years is an important goal both for maintaining individual quality of life and safeguarding social security systems. Against this background, we examined the development of healthy and unhealthy working life expectancy (HWLE/UHWLE) in the general population and for different educational groups.

Methods: The study is based on data from the German Socio-Economic Panel study, including 88 966 women and 85 585 men aged 50-64 years and covering four time periods (2001-05, 2006-2010, 2011-2015 and 2016-2020).

Background: With an attempt to understand possible mechanisms behind the severity-dependent development of type 2 diabetes (T2D) comorbidities, this study examines the trends of antidiabetic and cardiovascular diseases (CVD) medication prescriptions in individuals with T2D.

Methods: The study is based on claims data from a statutory health insurance provider in Lower Saxony, Germany. The period prevalence of antidiabetic and CVD medication prescriptions was examined for the periods 2005-2007, 2010-2012, and 2015-2017 in 240,241, 295,868, and 308,134 individuals with T2D, respectively.

Background: Diabetes is a growing epidemic worldwide and the effect of socioeconomic status (SES) is frequently acknowledged in the literature. This study aims to compare the effect of SES on diabetes prevalence in South Africa between 2003 and 2016. In addition, vulnerable groups regarding diabetes development in 2016 will be identified.

Unlabelled: Population ageing poses growing challenges to social security systems, in particular to public pension funds. The study analyses how Working Life Expectancy (WLE) and Healthy Working Life Expectancy (HWLE) in terms of three health indicators developed in Germany. Based on the German Socio-Economic Panel (GSOEP) from 2002 to 2018 (= 211,141), time trends in labour force rates, mental and physical Health-Related Quality of Life (HRQoL), self-rated health (SRH) and the respective combinations (health indicator*labour force) were analysed for all respondents aged 18-74.

Examine trends in limitations among young (15-39), middle-aged (40-64) and older age-groups (>=65) and their socioeconomic differences. Population-based European Social Survey data ( = 396,853) were used, covering 30 mostly European countries and spanning the time-period 2002-2018. Limitations were measured using a global activity limitations indicator.

Background: Morbidity is said to be compressed when the interval from the onset of a disease or disability to death becomes shorter over time, or when the incidence of the disease or disability declines over time. In the reverse situation, morbidity is said to be expanded.

Methods: This review is based on national and international studies retrieved by a selective literature search on secular trends in morbidity and mortality.

Background: The early COVID-19-pandemic was characterized by changes in decision making, decision-relevant value systems and the related perception of decisional uncertainties and conflicts resulting in decisional burden and stress. The vulnerability of clinical care professionals to these decisional dilemmas has not been characterized yet. Methods: A cross-sectional questionnaire study (540 patients, 322 physicians and 369 nurses in 11 institutions throughout Germany) was carried out.

Article Synopsis
  • The study examines how the COVID-19 pandemic has changed clinical management approaches, focusing on differences in perceptions among patients, nurses, and physicians regarding risks and healthcare decisions.
  • Data were collected from 1,231 stakeholders in oncology and psychiatry across 11 German institutions, revealing that 29.2% of professionals felt a significant increase in workload, particularly in psychiatry.
  • While healthcare professionals recognized substantial changes in their work, patients reported limited awareness of treatment modifications, highlighting a gap in perceptions that could hinder effective shared decision-making in clinical care.

The COVID-19 pandemic put healthcare systems, hospitals and medical personal under great pressure. Based on observations in Germany, we theorise a general model of rapid decision-making that makes sense of the growing complexity, risks and impact of missing evidence. While adapting decision-making algorithms, management, physicians, nurses and other healthcare professionals had to move into uncharted territory while addressing practical challenges and resolving normative (legal and ethical) conflicts.

(1) Background: Uncertainty is typical for a pandemic or similar healthcare crisis. This affects patients with resulting decisional conflicts and disturbed shared decision making during their treatment occurring to a very different extent. Sociodemographic factors and the individual perception of pandemic-related problems likely determine this decisional dilemma for patients and can characterize vulnerable groups with special susceptibility for decisional problems and related consequences.
