Use of semi-quantitative and quantitative culture methods and typing for studying the epidemiology of central venous catheter-related infections in neonates on parenteral nutrition.
(1/274)
To study the epidemiology - especially the impact of contaminated stopcocks - on central venous catheter (CVC) infection and catheter-related sepsis (CRS), semi-quantitative (SQ) and quantitative (Q) culture methods and typing of coagulase-negative staphylococci (CNS) were employed in 49 neonates with clinical signs of sepsis while receiving parenteral nutrition in the paediatric intensive care unit. The patients were divided into two groups according to stopcock contamination: group A consisted of 18 patients (36%) with contaminated stopcocks and group B consisted of 31 patients (64%) with sterile stopcocks. Five specimens were obtained from each patient, in addition to that from the stopcock: a swab taken from the skin surrounding the catheter puncture site; the CVC tip; the intradermal segment (IDC); and samples of parenteral fluid and blood. A total of 294 specimens (392 sites) was cultured and micro-organisms were identified. All CNS isolated were typed by biotyping, antibiogram, plasmid analysis and pulsed-field gel electrophoresis (PFGE), and the discriminatory power of the typing methods was compared. The CVC tips were infected in 25 patients (51%); 15 (83%) in group A and 10 (32%) in group B. Sepsis was detected in 24 neonates (49%), 13 in group A and 11 in group B. This was catheter-related in 15 patients (63%), 12 in group A and 3 in group B. CNS were recovered from 13 (52%) of 25 infected CVCs, nine in group A and four in group B. Sixty-five CNS isolates were recovered from these patients and belonged to 14 biotypes, 22 antibiograms, 22 plasmid profiles and 26 PFGE types. Typing showed that in six of nine patients in group A, CNS of the same type were recovered from the catheter tip and the stopcock, in one patient the catheter tip and skin isolates were the same and in two others the catheter tip isolates were different from stopcock and skin isolates. In all four patients in group B, different CNS types were recovered from CVC tips and skin. Bacteraemia was caused by CNS in 14 patients (58%), six in group A and eight in group B. Typing confirmed that nine cases (six in group A and three in group B) were catheter-related but five were not. SQ and Q culture methods and typing, especially by PFGE, allowed the study to determine that bacteria from contaminated stopcocks were frequently the source of CVC infection and CRS. (+info)
Slovenian experience on health care reform.
(2/274)
The health care system in Slovenia has undergone significant changes since 1992. The objectives were primarily economic and not medical, since the level of medical services rendered has been fairly high and there were limited needs for improvements. Many changes, such as privatization, have not yet achieved their main objective - improved efficiency and quality. We have, however, observed many positive results, such as the awareness of medical staff that the quality of the national health care system should not be taken as granted but should be based and developed on extremely careful planning. Health care reform packages are being designed primarily to address one important problem: cost containment. An important part of the reform was moving the major part of the health care budget outside of the state budget to make it more transparent and controllable and its use more subject to its primary intention.

Prevalence of Sjogren's syndrome in Slovenia.
(3/274)
OBJECTIVE: The aim of our study was to determine the prevalence of Sjogren's syndrome (SS) in Slovenia. METHODS: A total of 889 randomly selected adults were invited to take part in our study. The classification of SS was based on the validated criteria reported by a multicentre study performed in Europe. The participants were asked six simple questions for assessing both ocular and oral involvement. Information on co-morbidities and related treatment was collected at the same time. All participants were subjected to a Schirmer-I test, an unstimulated salivary flow test, as well as serological studies (rheumatoid factor, antinuclear antibodies, anti-Ro/SS-A and anti-La/SS-B antibodies). When indicated, Rose Bengal score, salivary scintigraphy and histopathological investigation of the minor salivary glands were carried out until three out of the six European classification criteria for SS were shown to be negative or until SS was diagnosed. RESULTS: Out of the 889 invited subjects, 332 (37.3%) participated in our study: 183 females, mean age (+/- S.D.) 52.2 +/- 13.7 yr (range 20-84) and 149 males, mean age (+/- S.D.) 56.3 +/- 12.9 yr (range 23-84). After the first visit, 244 of the 332 (73.5%) participants proved to be negative for three out of the six above-mentioned criteria, and were eliminated from further tests. The remaining 88 participants were consecutively subjected to Rose Bengal score, salivary scintigraphy and minor salivary gland biopsy. Fifteen participants refused to perform either one or more of the proposed tests at the second study stage. Two females of the 332 study participants [0.60% (exact 95% CI 0.07%, 2.16%)] fulfilled the criteria for primary SS. CONCLUSIONS: The estimated prevalence of definite SS in Slovenia is 0.60%. (+info)
Adrenal 21-hydroxylase gene mutations in Slovenian hyperandrogenic women: evaluation of corticotrophin stimulation and HLA polymorphisms in screening for carrier status.
(4/274)
OBJECTIVE: To study the incidence of 21-hydroxylase deficiency in Slovenian hyperandrogenic women, at the gene level. Previous endocrine studies indicated large differences in the incidence of 21-hydroxylase deficiency in hyperandrogenic women. The predictive values of the 17-hydroxyprogesterone (17-OHP) response to ACTH stimulation and of HLA typing in screening for carrier status were re-evaluated. DESIGN: Molecular analysis of CYP21 gene, ACTH stimulation and human leucocyte antigen (HLA) typing were performed in 83 consecutive Slovenian hyperandrogenic women. MEASUREMENTS: Cortisol and 17-OHP concentrations were measured at baseline and 60 min after ACTH stimulation. Basal adrenal androgen concentrations were also measured. RESULTS: None of 83 hyperandrogenic patients was affected with non-classical 21-hydroxylase deficiency, but 12 of 81 patients (14.8%) had high concentrations of 17-OHP after stimulation, indicative of carrier status. The increase in 17-OHP concentrations could be explained by a carrier status for CYP21 gene mutations in only three of 12 patients (25%), whereas seven of 69 patients (10. 1%) with normal concentrations of 17-OHP after stimulation were found to be carriers of CYP21 gene mutations, indicating low positive predictive values of ACTH stimulation as a screening test for carriers of 21-hydroxylase deficiency. In total, 11 carriers were identified among 83 patients: seven CYP21 gene deletions/conversions, two Gln(318)Stop and one Val(281)Leu mutation and one gene conversion extending from exon 4 to exon 7 were found. The association between Val(281)Leu mutation and HLA-B14 antigen was confirmed in this Slovenian population. CONCLUSIONS: Basal or ACTH-stimulated 17-OHP concentrations are not a good indicator of the carrier status for 21-hydroxylase deficiency among Slovenian hyperandrogenic patients. Reliable screening for carriers of 21-hydroxylase deficiency is possible only by molecular analysis of the CYP21 gene. (+info)
Characterisation of Borrelia burgdorferi sensu lato strains isolated from patients with skin manifestations of Lyme borreliosis residing in Slovenia.
(5/274)
Lyme borreliosis is the most prevalent tick-borne infection in Slovenia. Skin disorders are the most frequent clinical manifestations. The aim of the present study was to assess the phenotypic and genotypic diversity of a large number of human Borrelia burgdorferi sensu lato isolates and to evaluate any association between the isolates and different clinical manifestations. All 103 strains tested were from patients suffering from the skin disorders of Lyme borreliosis. Skin biopsies, cerebrospinal fluid and blood samples from patients were inoculated into modified Kelly Pettenkofer medium. Protein profiles were determined by SDS-PAGE and species identification and plasmid profiles by pulsed-field gel electrophoresis. MluI digestion profiles showed that 87 (84.5%) isolates belonged to B. afzelii, 15 (14.5%) to B. garinii and 1 (1%) to B. burgdorferi sensu stricto. The number of plasmids in each strain varied from three to seven, and the plasmid size ranged from 15 to 65 kb. Four isolates of B. garinii possessed multiple large plasmids and four isolates had a large plasmid dimer (three B. afzelii and one B. garinii). Isolates showed qualitative and quantitative differences in protein expression. The study found differences in the expression of OspB and OspC proteins between B. afzelii and B. garinii strains. OspB was expressed significantly more often by B. afzelii (78 of 87, 89.6%) than by B. garinii (4 of 15, 26.6%) isolates, while OspC protein was expressed significantly more often by B. garinii (14 of 15, 93.3%) than by B. afzelii (51 of 87, 58.6%) isolates. In Slovenia, B. afzelii causes the majority of skin lesions. The isolates investigated showed plasmid and protein diversity. Heterogeneity of the spirochaetes may be important for virulence, and may have implications for pathogenesis and therapy of the infection. Differences in immunodominant proteins also have an important impact on serological testing and vaccine development. (+info)
Hemorrhagic fever with renal syndrome in the Dolenjska region of Slovenia--a 10-year survey.
(6/274)
This report describes the first investigation of clinical findings for a larger series of patients with hemorrhagic fever with renal syndrome (HFRS) who were infected with Dobrava virus. From 1985 to 1995, 38 patients with serologically confirmed HFRS were hospitalized at the regional hospital in Novo mesto in the Dolenjska region of Slovenia. On the basis of results of serological examination, 24 patients had Dobrava virus infection, and 14 patients had Puumala virus infection. Complete clinical data were available for 31 patients. Eleven patients underwent hemodialysis for treatment of acute oliguric or anuric renal failure. Four patients, all infected by Dobrava virus, had signs of shock and severe bleeding. Three severely ill Dobrava virus-infected patients died of hemorrhagic complications. We have demonstrated that Dobrava and Puumala viruses coexist in a single region of endemicity and are capable of causing HFRS with significant differences in severity. (+info)
An evaluation of patient satisfaction with family practice care in Slovenia.
(7/274)
OBJECTIVE: To describe the level of patient satisfaction with family practice in Slovenia. DESIGN: An internationally developed instrument for patients' evaluations of general practice care was used in a postal survey. SETTING: A representative sample of 36 family practices in Slovenia. STUDY PARTICIPANTS: Sixty consecutive patients in every practice were approached and offered a self-administered questionnaire. A total of 2160 questionnaires were handed out. MAIN OUTCOME MEASURE: Percentages of patients reporting level of satisfaction on a 5-point Likert scale for the items in the questionnaire. RESULTS: On average 58.2% of respondents rated the level of care received as excellent. Waiting in the waiting room was the item rated poorest (26.0%). Participants were also less satisfied with perceived time during the consultation (51.6%) and with connectional aspects of care: the feeling that family practitioners showed interest in their personal situation (46.5%); the feeling that family practitioners made it easy to explain problems (49.1%). On the other hand patients praised many other aspects of family practice care in Slovenia: confidentiality of medical records (77.0%); listening capacity of their family physicians (69.4%); being able to speak to the family practitioner on the 'phone (72%). CONCLUSIONS: Patient satisfaction with family practice care in Slovenia was shown to be relatively high and can be compared to other European countries. The results showed areas in which quality improvement is required: organizational changes to shorten the waiting time in the waiting room and greater emphasis on communication skills. (+info)
Management of sickness absence: a quality improvement study from Slovenia.
(8/274)
PROBLEM: A need to improve the communication system between general practitioners (GPs) and the national health insurance institute's (NHII) committee of experts for the referral and approval of sickness leave for patients. DESIGN: A structured low cost quality improvement method for motivating GPs to change their current practice was developed. BACKGROUND AND SETTING: The study was done in Kranj health district in Slovenia. GPs and members of the committee of experts identified potential problems using a cause and effect diagram. The study period for baseline data collection was from November 1996 to December 1996, and the re-evaluation took place in May 1997. All GPs in Kranj health district (n = 78) took part. Data were collected on 443 patients referred by GPs to the NHII committee during the first phase of the study and 590 patients during the re-evaluation phase. KEY MEASURES FOR IMPROVEMENT: Reducing the number of cases reported by members of the committee of experts as causing problems after the intervention. Feedback to GPs about the success of the process. STRATEGIES FOR CHANGE: A combination of methods was used: posted feedback, a guideline on record keeping, and a guideline, called AID (analysis of incidental deviations from expected service--in Slovene: analiza izjemnih dogodkov), on processing medical documentation. EFFECTS OF CHANGE: An overall drop was observed in the number of cases that caused problems (from 44% to 26%, p < 0.001). The most common problem at baseline (19.4% of the problems) was the seventh most common at the re-evaluation, then contributing only 9.2% of total problems (p = 0.02). LESSONS LEARNT: The results support a quality improvement philosophy that empowers "owners" of the process to be the key resource in managing change, and they show the importance of the inner motivation of those involved. Despite working in a country undergoing transition, medical professionals were still willing to improve their performance. Nevertheless, structures and funding are needed to foster quality improvement initiatives and implement national policy on quality in health care. (+info)
