Mortality in people with mental disorders in Poland: A nationwide, register-based cohort study

BACKGROUND

Mortality among people with mental disorders is higher in comparison with the general population. There is a scarcity of studies on mortality in the abovementioned group of people in Central and Eastern European countries.

METHODS

The study aimed to assess all-cause mortality in people with mental disorders in Poland. We conducted a nationwide, register-based cohort study utilizing data from two nationwide registries in Poland: the registry of healthcare services reported to the National Health Fund (2009-2018) and the all-cause death registry from Statistics Poland (2019). We identified individuals who were consulted or hospitalized in public mental healthcare facilities and received at least one diagnosis of mental disorders (International Statistical Classification of Diseases and Health Problems [ICD-10]) from 2009 to 2018. Standardized mortality ratios (SMRs) were compared between people with a history of mental disorder and the general population.

RESULTS

The study comprised 4,038,517 people. The SMR for individuals with any mental disorder compared with the general population was 1.54. SMRs varied across diagnostic groups, with the highest values for substance use disorders (3.04; 95% CI 3.00-3.09), schizophrenia, schizotypal and delusional disorders (2.12; 95% CI 2.06-2.18), and pervasive and specific developmental disorders (1.68; 95% CI 1.08-2.29). When only inpatients were considered, all-cause mortality risk was almost threefold higher than in the general population (SMR 2.90; 95% CI 2.86-2.94).

CONCLUSIONS

In Poland, mortality in people with mental disorders is significantly higher than in the general population. The results provide a reference point for future longitudinal studies on mortality in Poland.

What opportunities do European early career psychiatrists have?

In the past century, biological, psychological and social sciences have brought significant progresses to psychiatry, building it is a broad medical specialty, closely linked to somatic medicine, psychology and society. Many psychiatrists early in their career have understood that it is easier to face these challenges in a collaborative way, and therefore there has been in the last decades a growth of local and national associations of psychiatric trainees and early career psychiatrists across Europe. In 2007, the European Psychiatric Association (EPA) has integrated in its program the "Young Psychiatrists Committee", an informal network of young psychiatrists. This Committee since 2010 has been known as the Early Career Psychiatrists Committee (ECPC). EPA has been making remarkable efforts towards supporting early career psychiatrists' education and participation in scientific congresses, promoting their professional growth and integration into the international professional community. Likewise, early career psychiatrists contribute to EPA with their motivation, enthusiasm and creative ideas, proving this initiative as an effective win-win cooperation.

Prevalence and correlates of depressive disorders in people with Type 2 diabetes: results from the International Prevalence and Treatment of Diabetes and Depression (INTERPRET-DD) study, a collaborative study carried out in 14 countries

AIMS

To assess the prevalence and management of depressive disorders in people with Type 2 diabetes in different countries.

METHODS

People with diabetes aged 18-65 years and treated in outpatient settings were recruited in 14 countries and underwent a psychiatric interview. Participants completed the Patient Health Questionnaire and the Problem Areas in Diabetes scale. Demographic and medical record data were collected.

RESULTS

A total of 2783 people with Type 2 diabetes (45.3% men, mean duration of diabetes 8.8 years) participated. Overall, 10.6% were diagnosed with current major depressive disorder and 17.0% reported moderate to severe levels of depressive symptomatology (Patient Health Questionnaire scores >9). Multivariable analyses showed that, after controlling for country, current major depressive disorder was significantly associated with gender (women) (P<0.0001), a lower level of education (P<0.05), doing less exercise (P<0.01), higher levels of diabetes distress (P<0.0001) and a previous diagnosis of major depressive disorder (P<0.0001). The proportion of those with either current major depressive disorder or moderate to severe levels of depressive symptomatology who had a diagnosis or any treatment for their depression recorded in their medical records was extremely low and non-existent in many countries (0-29.6%).

CONCLUSIONS

Our international study, the largest of this type ever undertaken, shows that people with diabetes frequently have depressive disorders and also significant levels of depressive symptoms. Our findings indicate that the identification and appropriate care for psychological and psychiatric problems is not the norm and suggest a lack of the comprehensive approach to diabetes management that is needed to improve clinical outcomes.
