[Psychiatric pharmacotherapy of older individuals with severe mental illness]

Characteristics of clinical-pharmacological recommendations in psychiatry in Germany

OBJECTIVE

Psychiatric patients in general, and elderly psychiatric patients in particular, are at risk of adverse drug reactions due to comorbidities and inappropriate polypharmacy. Interdisciplinary and clinical-pharmacologist-led medication reviews may contribute to medication safety in the field of psychiatry. In this study, we reported the frequency and characteristics of clinical-pharmacological recommendations in psychiatry, with a particular focus on geriatric psychiatry.

METHOD

A clinical pharmacologist, in collaboration with the attending psychiatrists and a consulting neurologist, conducted interdisciplinary medication reviews in a general psychiatric ward with a geropsychiatric focus at a university hospital over a 25-week period. All clinical and pharmacological recommendations were recorded and evaluated.

RESULTS

A total of 316 recommendations were made during 374 medication reviews. Indications/contraindications of drugs were the most frequently discussed topics (59/316; 18.7 %), followed by dose reductions (37/316; 11.7 %), and temporary or permanent discontinuation of medications (36/316; 11.4 %). The most frequent recommendations for dose reduction involvedbenzodiazepines (9/37; 24.3 %). An unclear or absent indication was the most common reason for recommending temporary or permanent discontinuation of the medication (6/36; 16.7 %).

CONCLUSION

Interdisciplinary clinical pharmacologist-led medication reviews represented a valuable contribution to medication management in psychiatric patients, particularly the elderly ones.

[Old and depressed and/or demented? - Pseudodepression vs. pseudodementia]

Many elderly patients suffer from both, depressive symptoms and cognitive deficits. Clinically, it oftentimes appears unclear whether the affective or the cognitive problems are primary or secondary. Modern molecular and imaging markers contribute to a more efficient distinction between depression and incipient dementia due to neurodegenerative, vascular, and other diseases. A careful history and clinical investigations are necessary to identify the underlying diseases, but they do not always offer sufficient therapeutic guidance. If in doubt, the condition should always be considered as potentially reversible and treated emphatically (but with age-appropriate caution).

[Identification of polypharmacy-associated risks among nursing home residents]

Einleitung

Multimorbidität im Alter ist u. a. ein Grund für intensivierte Pharmakotherapie. Gleichzeitig kann es mit steigender Medikamentenzahl zu einer Zunahme der Multimorbidität kommen, insbesondere wenn Interaktionen zwischen den Wirkstoffen zu unerwünschten Arzneiwirkungen (UAW) führen. Ziel dieser Untersuchung war es, in einer Pilotstudie Patienten zu identifizieren, die einem erhöhten Risiko für UAW unterliegen.

Methoden

In einer Querschnittserhebung wurden 918 in Heimen lebende psychiatrisch behandelte Alterspatienten untersucht (Altersmittel: 79,3 (±11,6) Jahre; 31,8 % Männer). Es kamen exemplarisch verschiedene Methoden zur Identifikation von möglichen Risikopatienten zur Anwendung: eine die Interaktionen der Gesamtmedikation erfassende „Clinical-Decision-Support-Software“(CDSS)-Onlinedatenbank, mediQ, und eine Negativliste, die pauschal zu vermeidende Präparate indiziert, die PRISCUS-Liste.

Ergebnis

Es hatten 76,3 % aller Studienpatienten bei Betrachtung der Gesamtmedikation ein klinisch relevantes Interaktionsrisiko (IR), 2,2 % standen unter einem darüber hinausgehenden potenziell starken UAW-Risiko durch Interaktionen. Ungefähr ein Viertel der untersuchten Studienpopulation erhielt potenziell inadäquate Medikamente gemäß PRISCUS.

Schlussfolgerung

Diese unterschiedlichen Zahlen zeigen die Komplexität der eindeutigen Identifikation von Risikopatienten am Beispiel dieser beiden, auf unterschiedlicher Grundlage basierenden Instrumente. Trotz des technischen Fortschritts sollte der Schwerpunkt der UAW-Vermeidung unverändert darauf liegen, Medikamente erst nach besonders gründlicher Prüfung der klinischen Indikation zu verordnen und eine adäquate Verlaufskontrolle zu gewährleisten. Die neuen CDSS oder Negativlisten bieten hierbei Unterstützung.

Factors of Negative Affect in Elderly Patients With Substance Use Disorders During COVID-19 Pandemic

Background: The outbreak of the novel coronavirus disease 2019 (COVID-19) has become the greatest public health emergency and has attracted global attention. During the COVID-19 pandemic, the negative affect (NA) of elderly patients with substance use disorders (SUDs) has also become a more serious public concern. The current study aims to clarify the NA and its influencing factors in elderly patients with SUDs during the pandemic. Methods: Two psychiatrists conducted semi-structured interviews with 77 SUD patients aged above 50 years to collect their demographical information and certain drug use characteristics. Barratt Impulse Scale and the Positive and Negative Affect Scale were used to obtain information about patients' self-reported impulsivity and NA. Results: Univariate linear regression analysis showed that NA was positively correlated with the frequency of drug use, type of SUDs, cravings during COVID-19, and impulsivity. Multiple linear regression analysis showed that being female, higher frequency of drug use, stronger cravings, and greater impulsiveness jointly accounted for the variation of NA in elderly patients with SUDs. Conclusions: This study confirmed that, during the COVID-19 pandemic, gender, frequency of drug use, cravings, and impulsivity were associated with NA in elderly patients with SUDs. This study provided a theoretical basis for clinicians to reduce the patients' NA.

[Somatic risks in elderly people with severe psychiatric illnesses]

BACKGROUND

Aged patients with severe mental illness (SMI) suffer from a high risk for functional impairment and a high load of somatic comorbidities. Until now, there has been a lack of systematic studies on this patient population in later life. This review summarizes the most significant somatic comorbidities and discusses the consequences for the medical care of this elderly group of patients.

METHODS

A selective narrative review based on PubMed research and observations in clinical practice.

RESULTS

Life expectancy is shortened by approximately 10 years in patients with SMI. The main reasons are somatic comorbidities, particularly lung and respiratory tract disorders, metabolic syndrome with its subsequent cardiovascular complications, in addition to osteoporosis and fractures with a complicated clinical course. Although life expectancy is shortened, the number of geriatric patients with SMI is increasing and requires special attention to be given to out-patient psychosocial care, self-management of somatic diseases, and to age-appropriate continuation of psychiatric treatment.

CONCLUSION

The life expectancy of patients with SMI is reduced because of their typically somatic comorbidity, but they are reaching increasingly advanced ages as a consequence of improved treatment possibilities. They often require special attention in their diagnostic work-up and support in the management of their treatment. Collaborative care linking medical geriatric and geronto-psychiatric treatment facilities is helpful in the the interdisciplinary therapy required.
