Decision-making capacity (DMC) among psychiatric inpatients is a pivotal clinical concern. A review by Okai et al. (2007) suggested that most psychiatric inpatients have DMC for treatment, and its assessment is reliable. Nevertheless, the high heterogeneity and mixed results from other studies mean there is considerable uncertainty around this topic. This study aimed to update Okai's research by conducting a systematic review with meta-analysis to address heterogeneity. We performed a systematic search across four databases, yielding 5351 results. We extracted data from 20 eligible studies on adult psychiatric inpatients, covering DMC assessments from 2006 to May 2022. A meta-analysis was conducted on 11 papers, and a quality assessment was performed. The study protocol was registered on PROSPERO (ID: CRD42022330074). The proportion of patients with DMC for treatment varied widely based on treatment setting, the specific decision and assessment methods. Reliable capacity assessment was feasible. The Mini-Mental State Examination (MMSE), Global Assessment of Function (GAF), and Brief Psychiatric Rating Scale (BPRS) predicted clinical judgments of capacity. Schizophrenia and bipolar mania were linked to the highest incapacity rates, while depression and anxiety symptoms were associated with better capacity and insight. Unemployment was the only sociodemographic factor correlated with incapacity. Assessing mental capacity is replicable, with most psychiatric inpatients able to make treatment decisions. However, this capacity varies with admission stage, formal status (involuntary or voluntary), and information provided. The severity of psychopathology is linked to mental capacity, though detailed psychopathological data are limited.

There are great variations in the way psychotropic drugs are prescribed. Most experts are in favour of psychopharmacological monotherapy, but little is known about the extent to which it is actually practised. A survey of the psychopharmacological medication of all patients under treatment was carried out in three Austrian psychiatric clinics of various types on two separate days. A psychiatric university clinic, the psychiatric department of a general hospital and a regional mental hospital were selected for the survey.

It was established that only 8% to 22% of the patients underwent psycho-pharmacological monotherapy and that the patients received 2.2 to 3.3 psychotropics on average. Five to 22% of the patients received five or more psychotropic agents. The results are presented in more detail in relation to the diagnoses of schizophrenia and depression.

The rare occurence of monotherapy might be due to unsound treatment regimens in some instances, but much more to a general trend in psychiatry fostering polydrug use.

This paper presents data obtained in a one-day census investigation in five European countries (Austria, Hungary, Romania, Slovakia, Slovenia). The census forms were filled in for 4191 psychiatric inpatients. Concerning legal status, 11.2% were hospitalised against their will (committed) and 21.4% were treated in a ward with locked doors. There was only a small correlation between commitment and treatment in a locked ward. More frequent than treatment of committed patients in locked wards was treatment of committed patients in open wards (Austria, Hungary) and treatment of voluntary patients in closed wards (Slovakia, Slovenia). Concerning employment, 27.7% of patients aged 18–60 held a job before admission. The vast majority of patients (84.8%) had a length of stay of less than 3 months. A comparison of these data with the results of a study performed in 1996 and using the same method shows a decrease of rates of long-stay patients. In 1996 the rates of employment were significantly higher in Romania (39.3%) and Slovakia (42.5%) compared to Austria (30.7%). These differences disappeared in 1999 due to decreasing rates of employment in Romania and Slovakia. The numbers of mental health personnel varies between types of institution (university or non-university) and countries, being highest in Austria and lowest in Romania. A considerable increase in the numbers of staff was found in Slovakia.

This objectives of this study were three-fold: retrospectively evaluate anxiolytic/hypnotic consumption by psychiatric inpatients, identify the risk factors of prolonged intakes, and prospectively measure the impact of hospitalisation on the use of those drugs. Three hundred and seventy-six patients hospitalised in 11 psychiatric departments in the Paris region were studied using a structured interview for the anxiolytic/hypnotic treatments, DSM-III-R criteria, GHQ-12, HAD, Spiegel's questionnaire, COVI's anxiety scale and the CGI. Eighty-five per cent of the patients had taken one anxiolytic/hypnotic or more in the 3 months preceding hospitalisation. Hospitalisation induced little change in anxiolytic/hypnotic use: dosage frequency increased from 77% to 84% between the week preceding hospitalisation and that preceding discharge; 26% of consumers were taking at least two anxiolytics or two hypnotics in the first period vs. 23% in the second. The absence of withdrawal during hospitalisation was related to the high age and a diagnosis of depression rather than schizophrenia, to the existence of continuous intake over the 3 months preceding hospitalisation and to higher drug doses during the 7 days preceding hospitalisation. Prescription of treatment at the end of hospitalisation in previously non-user subjects was related to a higher HAD anxiety score at discharge.

Background: People with severe mental illness are at an increased risk of physical health problems including diabetes.

Aims: To identify the proportion of patients with diabetes in specialist secure psychiatric care, establish current practice in diabetes care and management, and clarify the role of the psychiatric medical team versus the on-site general practitioner.

Method: Hospital-wide data collection from electronic and paper case notes of all identified diabetic patients. Audit standards were based on current National Institute for Clinical Excellence guidelines.

Results: 64 out of 548 patients (11.7%) were identified with a diagnosis of diabetes. 18 (28%) of these patients had an individual care plan to address their diabetic management and risk. The majority of patients had regular blood glucose and HbA1c monitoring.

Clinical implications: Patients should receive regular structured education sessions, regular feedback about their own management, and individual care plans that include the management of common and potentially life threatening complications. These are essential components of providing good quality diabetes care. Clinical audit may provide a means of identifying and rectifying problems in relation to diabetes care in long-stay psychiatric inpatients.

This paper investigates the characteristics of those under inpatient psychiatric care in 1901 in the context of a policy formulated to provide institutional care and treatment for mentally ill persons. It presents data on admissions, discharges and deaths, their demographic and clinical characteristics and reported outcomes.

Objectives: The objectives of this paper are to review the presentation of hyponatraemia and diagnose its cause in psychiatric inpatients.

Method: Episodes of significant hyponatraemia (sodium <130mmol/L) were identified from computerised biochemical data and a retrospective review of patients' notes was carried out.

Result. The diagnoses of hyponatraemia reached were different for the two groups of patients studied, adults of over 65 years and under 65 years. Carbamazepine, polydipsia and medical conditions were found as causes in the below 65 age group. Diuretics, medical conditions and lofepramine were identified as causes in the over 65 age group. Inpatients with polydipsia below the age of 65 had lower sodium (p = 0.013) and urea levels (p = 0.00059) than other groups and patients with carbamazepine induced hyponatraemia tended to have episodic hypocalcaemia (p = 0.056). These groups were compared using Fisher's exact test. This study also showed the overall frequency of serum sodium of less than 135mmol/L to be 9.5% in psychiatric inpatients.

Conclusion: Hyponatraemia is a not uncommon finding in psychiatric inpatients. Attention to drug therapy and biochemical findings are helpful in its diagnosis. Accurate diagnosis is usually possible and may vary according to age-group.
