Parasuicide: The value of suicidal intent and various motives as predictors of future suicidal behaviour

Abstract

The main aim of the study was to examine whether various aspects of suicidal intent or various motives for an index parasuicide can predict nonfatal or fatal repetition of suicidal behaviour. 776 parasuicide patients from 5 Nordic regions participating in the WHO/EURO Multicentre Study on Parasuicide were followed for one year. The Suicide Intent Scale (SIS) and the Motives for Parasuicide Questionnaire (MPQ) were used as predictor variables. A low level of suicidal intent predicted nonfatal repetition. The motive “make things easier for someone” differentiated female repeaters From male repeaters. The report of an unclear motive was the only significant predictor of fatal repetition. Suicidal intent and various motives for a parasuicide have some value in predicting repetition of suicidal behaviour. but should, perhaps. in future studies be combined with other variables in order to increase the predictive value.     

Treatment needs, diagnoses and use of services for acutely admitted psychiatric patients in northwest Russia and northern Norway

Background

We compared demography, diagnoses and clinical needs in acutely admitted psychiatric hospital patients in northwest Russia and northern Norway.

Method

All acutely admitted psychiatric patients in 1 psychiatric hospital in north-west Russia and 2 in northern Norway were in a three months period assessed with HoNOS and a Norwegian form developed to study acute psychiatric services (MAP). Data from a total of 841 patients were analysed (377 Norwegian, 464 Russian) with univariate and multivariate statistics.

Results

Russian patients were more often males who had paid work. 2/3 were diagnosed with alcohol and organic disorders, and 70% reported problems related to sleep. Depression was widespread, as were problems associated with occupation. Many more Norwegian patients were on various forms of social security and lived in community supported homes. They had a clinical profile of affective disorders, use of drugs, suicidality and problems with activities involved of daily life. Slightly more Norwegian patients were involuntary admitted.

Conclusion

Acutely admitted psychiatric patients in North West Russia and Northern Norwegian showed different clinical profiles: alcohol, depression and organic disorders characterised Russian patients, affective disorders, suicidality and use of drugs characterised the Norwegians. Whereas Norwegian patients are mainly referred from GPs the Russians come via 1.line psychiatric services (“dispensaries”). Average length of stay for Russian patients was 2.5 times longer than that of the Norwegian.     

Simulation-assisted burn disaster planning

The aim of the study was to evaluate the Swedish medical systems response to a mass casualty burn incident in a rural area with a focus on national coordination of burn care. Data were collected from two simulations of a mass casualty incident with burns in a rural area in the mid portion of Sweden close to the Norwegian border, based on a large inventory of emergency resources available in this area as well as regional hospitals, university hospitals and burn centres in Sweden and abroad. The simulation system Emergo Train System^® (ETS) was used and risk for preventable death and complications were used as outcome measures: simulation I, 18.5% (n = 13) preventable deaths and 15.5% (n = 11) preventable complications; simulation II, 11.4% (n = 8) preventable deaths and 11.4% (n = 8) preventable complications. The last T1 patient was evacuated after 7 h in simulation I, compared with 5 h in simulation II. Better national coordination of burn care and more timely distribution based on the experience from the first simulation, and possibly a learning effect, led to a better patient outcome in simulation II. The experience using a system that combines both process and outcome indicators can create important results that may support disaster planning.     

Psychotherapy supervision conducted via videoconferencing: A qualitative study of users' experiences

Forty-three patients who had been treated in hospital for major depression were studied 1 to 2 years after discharge. Patients retrospectively ranked physical exercise as the most important element in the comprehensive treatment programme. Most subjects continued with regular exercise after discharge, and most of these exercised aerobically at least 2 h a week. Exercisers tended to have lower depression scores at follow-up examination than nonexercisers.

Abstract

Objective: Monitoring of ongoing psychotherapy is of crucial importance in improving the quality of mental health care by detecting therapies being off track, which requires that the instrument used is psychometrically sound. This study investigates the psychometric properties of the Norwegian version of the Outcome Questionnaire 45.2 (OQ-45) and situates the results in an international context.Method: Data from one non-clinical sample (N = 338) and one clinical sample (N = 560) were compared to international samples investigating reliability, cut-offs, and factor structure. Results: The results show adequate reliability and concurrent validity. Conclusions: The means, clinical cut-offs, and the reliable change index vary across countries. However, the means of the OQ-45 for nonclinical samples correlate highly with external values of national well-being, indicating that the OQ-45 is a valid instrument internationally. The factor analyses in the present study do not confirm the hypothesized factor structure of the OQ-45, but are similar to the results internationally.     

Penicillin G Treatment in Infective Endocarditis Patients – Does Standard Dosing Result in Therapeutic Plasma Concentrations?

Penicillin G is frequently used to treat infective endocarditis (IE) caused by streptococci, penicillin‐susceptible staphylococci and enterococci. Appropriate antibiotic exposure is essential for survival and reduces the risk of complications and drug resistance development. We determined penicillin G plasma concentration [p‐penicillin] once weekly in 46 IE patients. The aim was to evaluate whether penicillin G 3 g every 6 hr (q6 h) resulted in therapeutic concentrations and to analyse potential factors that influence inter‐ and intra‐individual variability, using linear regression and a random coefficient model. [P‐penicillin] at 3 hr and at 6 hr was compared with the minimal inhibitory concentration (MIC) of the bacteria isolated from blood cultures to evaluate the following PK/PD targets: 50% fT > MIC and 100% fT > MIC. [P‐penicillin] varied notably between patients and was associated with age, weight, p‐creatinine and estimated creatinine clearance (eCLcr). Additionally, an increase in [p‐penicillin] during the treatment period showed strong correlation with age, a low eCLcr, a low weight and a low p‐albumin. Of the 46 patients, 96% had [p‐penicillin] that resulted in 50% fT > MIC, while 71% had [p‐penicillin] resulting in 100% fT > MIC. The majority of patients not achieving the 100% fT > MIC target were infected with enterococci. Streptococci and staphylococci isolated from blood cultures were highly susceptible to penicillin G. Our results suggest that penicillin G 3 g q6 h is suitable to treat IE caused by streptococci and penicillin‐susceptible staphylococci, but caution must be taken when the infection is caused by enterococci. When treating enterococci, therapeutic drug monitoring should be applied to optimize penicillin G dosing and exposure.     

A model for an uncertainty budget for preanalytical variables in clinical chemistry analyses

BACKGROUND: We sought a practical method to calculate preanalytical uncertainties. In clinical chemistry measurements, the combined preanalytical uncertainty is a function of the magnitude and probability distribution of the different uncertainty sources and the number of such sources. METHODS: Results from an optimal practice for handling of the blood samples (termed the standard method) were compared with alternative methods that deviate from the standard method but are used in current practice. For categorically distributed uncertainty sources (e.g., use of different kinds of blood tubes), alternative treatments were modeled discretely using a known probability distribution for each alternative. For continuously distributed sources (e.g., clotting time), we assumed a rectangular distribution. We calculated the expectation, variance, and SD of differences between results from current practice and the standard method. We tabulated uncertainty budgets for the differences between current practice and the standard method for each uncertainty source. The expected individual biases and variances were summed to obtain the combined expected bias and variance. RESULTS: The combined expected bias (SD) for glucose was -0.15 (0.130) mmol/L, with prolonged clotting time giving the greatest contribution. The combined expected bias (SD) for calcium was -0.011 (0.0182) mmol/L, for magnesium 0.006 (0.026) mmol/L, and for creatinine 0.5 (1.81) micromol/L. CONCLUSION: By comparing a standard method for preanalytical sample handling to alternative methods used in current practice, and considering the distribution of alternative methods, our modeling approach allows the development of an uncertainty budget for preanalytical variables in clinical chemistry analyses.
