Quality assessment and assurance in diagnostic imaging. Theoretical and practical considerations and a quality audit of the excretory urogram

Concepts necessary to an understanding of the basics of quality assurance audits are presented. Included are specific examples that bridged theory and practice by applying the protocol to a real-life diagnostic imaging situation. This method meets the present requirements of the Joint Commission of the Accrediation of Hospitals.     

Readiness for change and readiness for help-seeking: a composite assessment of client motivation

AIMS: To investigate the correspondence between readiness for behaviour change in general and readiness for alcohol related help-seeking in particular. A related aim was to examine how, if at all, measures of dependence severity, use, and consequences were related to a composite measure depicting agreements and disagreements between general change readiness and help-seeking readiness. METHODS: Non-treatment seeking alcohol-dependent patients, numbering 549, from general hospitals in Germany were interviewed. RESULTS: When taking into account both dimensions of motivation, findings indicate 42% of the subjects were characterized by different motivation levels regarding readiness for change and readiness for help-seeking. Higher help-seeking readiness was associated with higher alcohol problem severity. Readiness to change was not affected by alcohol problem severity. CONCLUSIONS: Findings underscore the need to evaluate both motivational constructs in determining clients' need and receptivity to formal help.     

Relationships of psychiatric disorders with overweight and obesity in an adult general population

OBJECTIVE: To explore relationships of smoking and risk drinking status, nicotine and alcohol dependence, and anxiety, depressive, and somatoform disorders with overweight and obesity. RESEARCH METHODS AND PROCEDURES: A probability sample was drawn that was representative for the adult general population, 18 to 64 years of age, in one region of Germany; the participation rate was 70.2%. After excluding those who were pregnant or had a current eating disorder according to the DSM-IV, 4063 individuals remained. Overweight and obesity were defined according to the BMI that was assessed in the face-to-face in-home standardized interview (Composite International Diagnostic Interview) on psychiatric disorders. RESULTS: Men with a former nicotine dependence had higher odds of being overweight than men who never had a nicotine dependence (adjusted odds ratio, 1.5; confidence interval, 1.1 to 2.1). Men at current risk for drinking and current alcohol-dependent or abusing men had lower odds of being overweight compared with men who never were alcohol dependent, abusing, or at risk for drinking (adjusted odds ratio, 0.3; confidence interval, 0.8 to 0.9). Effect sizes were small. No relationship of overweight with depressive, anxiety, or somatoform disorders was found in the multivariate analysis. DISCUSSION: There is a relationship between being overweight and nicotine and alcohol dependence or abuse among men but not among women. Even though one reason for women to refrain from quitting smoking is the fear of weight gain, these results do not support this. This information could help convince women to try to quit smoking.     

Colon perforation following percutaneous nephrostomy and renal calculus removal

Two patients had colonic perforation as a result of percutaneous nephrostomy placement followed by track dilatation and renal calculus removal. We present the technical aspects of nephrostomy placement and stone removal, as well as the clinical diagnosis and management of these cases. Both patients recovered well with conservative therapy and required no surgical intervention. This report reviews the anatomic considerations for percutaneous nephrostomy in patients undergoing renal stone removal.     

Smoking, nicotine dependence and psychiatric comorbidity--a population-based study including smoking cessation after three years

BACKGROUND: Evidence suggests that nicotine-dependent smokers are at increased risk for psychiatric comorbidity but general population data that included the number of nicotine dependence and withdrawal symptoms according to DSM-IV, the Fagerstrom Test for Nicotine Dependence (FTND), somatoform disorders and the number of psychiatric diagnoses are rare. The goal of the present study was to analyse relationships of smoking and nicotine dependence with psychiatric disease and whether psychiatric disease predicts the sustaining of smoking after three years. METHODS: Cohort study with a random adult population sample in a northern German region (N = 4075) including a baseline measurement of ever daily smokers aged 18-64 (n = 2458), a first follow-up of the current smokers at baseline (n = 1552) after 30 months and a second follow-up after 36 months. Measures included DSM-IV diagnoses by the Composite International Diagnostic Interview, FTND, smoking cessation by interview. RESULTS: Current daily smokers showed higher odds of a substance use disorder other than nicotine dependence compared with never smokers (odds ratio, OR, 4.6; confidence interval, CI, 2.9-7.2), affective (OR 1.8; CI 1.4-2.5), anxiety (OR 1.6; CI 1.2-2.0) or somatoform disorder (OR 1.4; CI 1.0-1.8). DSM-IV nicotine dependence and the FTND were positively related with the number of psychiatric diagnoses. Psychiatric comorbidity did not predict the maintenance of smoking or quitting. CONCLUSIONS: Findings of increased rates of mental disorders among smokers and nicotine-dependent smokers in the adult general population are supported by this study. The number of nicotine dependence and withdrawal symptoms are related to mental disorders. In addition, somatoform disorders show relationships with smoking similar to relationships with depressive or anxiety disorders. The intention to stop smoking should be proactively supported among these comorbid patients.     

Relation among stage of change, demographic characteristics, smoking history, and nicotine dependence in an adult German population

BACKGROUND: The aim of this study was to provide evidence about the individual intention to quit smoking and accompanying characteristics in a country with a low amount of tobacco control (TC) provisions. METHODS: This study used a random sample of the population aged 18-64 in a German area to make a quantitative estimation of the stages of change to quit smoking among current smokers who had at least one quit attempt (n = 1075). RESULTS: The rate of those who did not intend to stop smoking (precontemplators) was 76.4%, that of those who intended to quit during the next 6 months (contemplators) was 17.0%, and that of those who intended to quit during the next 4 weeks was 6.6%. The three groups did not differ according to gender or age. Of those who had at least 16 years of education, more were contemplators than were those with fewer years of education. Among those who had somatic complaints or nausea from smoking, who had their first cigarette within 1 h or less after awakening, and who had more quit attempts, more were in the contemplation or preparation stage. CONCLUSIONS: Nicotine dependence may add to contemplating about quitting. The precontemplation rate was substantially higher than in samples from nations or states which show a large amount of TC provisions.     

Screening for mental health: validity of the MHI-5 using DSM-IV Axis I psychiatric disorders as gold standard

Short screening questionnaires for mental health are useful tools for research and clinical practice, e.g. they could play a major role in detecting patients with psychiatric disorders in primary care. The present study tests the validity of the five-item Mental Health Inventory (MHI-5) screening test using DSM-IV Axis I diagnoses as a gold standard and analyzes its performance in different diagnostic groups. A random sample was drawn from the resident registration office files in northern Germany. Personal interviews with a response rate of 70% were conducted. Of the sample, 4036 respondents filled in the MHI-5. DSM-IV diagnoses were assessed using the Munich Composite International Diagnostic Interview (M-CIDI). The area under the receiver operating characteristics curve (AUC) of 0.72 in identifying any DSM-IV Axis I disorder (except substance use) is not satisfying. The MHI-5 revealed best performance for mood (AUC: 0.88) followed by anxiety disorders (AUC: 0.71). Sensitivity and specificity were poor for somatoform and substance use disorders, especially in cases without comorbid mood or anxiety disorder. The power to detect mood and anxiety disorders of the MHI-5 was better for the 4-week compared with the 12-month diagnoses. The MHI-5 can be recommended to screen for mood disorders. Data have to be confirmed for primary care settings.
