Results of the 1993 survey of the healthcare materiel management and central service professions

Our 1993 professional survey showed materiel managers gearing for change, as they expect to see their ranks decrease in number but gain influence. Central service managers seem to be warily watching CS contract services. Salaries increased more for materiel managers than CS managers, though both showed some losses in some regions. Bed size again had a direct bearing on compensation, and those who made more tended to have more benefits. Benefits were lost by 14 percent of materiel managers and 21 percent of CS managers. Few of either group changed jobs. Materiel managers again reported in the largest numbers to finance and CS to materiel management, though this reporting structure seems to be weakening. Education gains were up for both groups, and membership to one or more associations was high for both groups. Materiel managers seem more satisfied with their jobs than they did last year, but CS managers seem decidely less satisfied.     

Regionalization: Canadian-style integrated networks. A case study

Developing a successful integrated network requires senior management to scrutinize and apportion available resources--technologies, beds, personnel and so forth--on a regional basis. Regionalization--the Canadian version of integrated networks--increasingly came to be seen as the answer that would work, and in New Brunswick the broadest efforts have been made. Fifty-one hospital and health center boards across the province were dissolved, and health services in the province were apportioned into seven regional hospital corporations, with an eighth encompassing the entire province. At Region 3 Hospital Corporation, a strategic planning exercise helped management identify resources. New information systems were put in place to provide resource utilization information for designating facilities for the level of care they would provide, as well as to provide feedback to physicians and develop critical pathways. Support services were consolidated. Budget reductions caused the curtailment of new service plans, but also increased cooperation among clinicians and non-clinical managers. Layoffs created worker bumping throughout the system to accommodate union seniority rules. Nearly three years into regionalization, most people in New Brunswick say they are satisfied with the healthcare they receive.     

Evidence against a role of nitric oxide in the indirect negative inotropic-effect of M-cholinoceptor stimulation in human ventricular myocardium

Nitric oxide (NO) has been reported to mediate several effects in response to muscarinic cholinergic stimulation in cardiovascular tissues. Recently, an attenuation of guinea pig cardiac myocyte contraction by NO has been described. The aim of the present study was to determine whether the indirect negative inotropic effect of M-cholinoceptor stimulation in human myocardium is in part due to an effect of endogenous NO. Therefore, the effect of carbachol was studied under control conditions and during inhibition of NO-synthase by pretreatment with N^G-monomethyl-l-arginine (NMMA). Functional experiments were performed in isolated, electrically driven (1 Hz, 37°C) left ventricular papillary muscle strips of human myocardium. Since cytokines have been reported to be increased in the serum of patients with heart failure and could induce NO-synthase activity in failing myocardium, we compared samples from nonfailing and terminally failing (classified as NYHA IV) hearts. The indirect negative inotropic effect of carbachol (10 mol/l) was studied in the presence of the \-adrenoceptor agonist isoprenaline (0.03 mol/l).After stimulation with isoprenaline, carbachol significantly (P < 0.05) reduced force of contraction. This effect was diminished in failing myocardium compared to nonfailing, probably due to the diminished inotropic response most likely due to the lower cAMP levels in response to \-adrenoceptor stimulation in the former condition. Pretreatment with NMMA (100 mol/l) altered the antiadrenergic effect of carbachol neither in nonfailing nor in failing preparations. Furthermore, inhibition of guanylyl cyclase, the target enzyme of NO, by preincubation with methylene blue (10 mol/l) for 30 min had no effect on the carbachol-induced decrease in force of contraction. Basal force of contraction, as well as the positive inotropic effect of isoprenaline remained unaffected by NMMA or methylene blue.The present study provides evidence that the indirect negative inotropic effect of M-cholinoceptor agonists is not due to an effect of NO in the human myocardium. Furthermore, the well known enhancement of cGMP in response to M-cholinoceptor stimulation appears not to be involved in this antiadrenergic effect.     

Associations between behavioural and emotional problems in adolescence and maladjustment in young adulthood

This study was designed to investigate associations between emotional and behavioural problems in adolescence and psychopathology in young adulthood.Seven hundred and six 11- to 16-year-olds from the Dutch general population were followed across a period of 8 years and 8 months. Subjects were initially assessed using the Child Behaviour Checklist (CBCL). At follow-up, a subsample of 131 subjects were assessed for DSM-III-R Axis 1 diagnoses with the SCAN (a semi-structured interview), while the Global Assessment of Functioning scale and the Groningen Social Disabilities Schedule were used to assess functioning in daily life. Scores on the CBCL scales Withdrawn, Anxious/Depressed, Somatic Complaints, Social Problems and Thought Problems in adolescence were associated with DSM-III-R symptomatology or dysfunctioning in young adulthood.     

Radiology: an opportunity waiting to happen

This article discusses the opportunity for cost savings in radiology for the materiel manager who builds a partnership with a strong potential ally in the department--the radiology administrator.     

Work Place Health Promotion

This article deals with the question of whether and how much workplace health promotion measures have infiltrated the working world and which factors determined the results of health promotion programs for the enterprises. To answer this question we conducted a longitudinal study (measuring times: 1997 and 2003) in 150 enterprises in Hessen and Thueringen of the service sector and metal branch. A standardized questionnaire was used to collect the data. One of the results was that the high level of occupational safety and health (OSH) obtained was greatly appreciated by the enterprises interviewed. Many of the enterprises (82.7%) were able to implement at least one workplace health promotion (WHP) measure, mostly assessments of occupational health risks and behavior-oriented offers. The portion of businesses with a very good to sufficient level of workplace health promotion increased clearly from 16.0% in 1997 to 27.4% in 2003. Half of the enterprises interviewed confirmed the need for information and consultation in questions about occupational safety and health issues and workplace health promotion. They expected support particularly from the institutions for statutory occupational accident insurance, health insurance companies, public institutions for labor protection and safety engineering, as well as from the advisory boards of the trade unions. These institutions definitely need to address the consultation requests from the enterprises, as the lack of information and contact persons was one of the reasons why workplace health promotion measures could not be implemented.This study was commissioned by the Hans Boeckler Foundation and the SMBG and translated by Evelyn Jäck     

Phylogenetic reconstruction of Mycobacterium tuberculosis within four settings of the Caribbean region: tree comparative analyse and first appraisal on their phylogeography.

In order to compare phylogenetic methods and to reconstruct the evolutionary history of the tubercle bacilli, a set of macro-array-based genotyping data of Mycobacterium tuberculosis clinical isolates (called spoligotyping for spacer oligonucleotide typing, which assays the variability of the Direct Repeat -DR- locus), was analyzed in four settings of the Caribbean region (Guadeloupe, Martinique, Cuba and Haiti). A set of 47 alleles, split into 26 shared and 21 unique alleles) representative of 321 individual M. tuberculosis clinical isolates from patients residing in the above regions was studied. The following methods (and software in brackets) were investigated: numerical taxonomy distance methods (TAXOTRON), maximum parsimony procedure (PAUP), median-joining networks (NETWORK), and nested clade analysis (GEODIS). Results using these methods were analyzed, compared and discussed. The latter method (GEODIS) was investigated in detail by introducing geographical data together with genetic variability results to detect a link between population structure and population history, and to test the null hypothesis of no association between geography and genotypes. Irrespective of the methods used, our findings demonstrate that a core structure of four families (or clades) of M. tuberculosis strains is highly prevalent within the islands studied, indirectly reflecting passed colonization history of these different settings. Specificity of M. tuberculosis genotypes in each of the islands is discussed in the light of their respective colonial and contemporary histories.
