Prevalence study of Legionella spp. contamination in Greek hospitals

Water and swab samples were collected from 13 hospitals and analyzed for Legionella counts. Legionella was detected in eight out of 13 hospitals and in 22 of 130 water and swab-collected samples. A total of 72.7% of the strains were L. pneumophila ser. 1, 22.7% were L. pneumophila ser. 2-14, and 4.5% did not belong to any of these groups. AFLP typing of the L. pneumophila ser. 1 strains generated two distinguishable AFLP types. There was no significant correlation to the sample type with Legionella recovery. Legionella isolation was more likely to occur in the cooling towers than the water system. Water temperatures of 30-40 degrees C seem to favor Legionella growth. Of the 265 serum samples taken from the medical and technical staff for the control of IgG titre, 89.4% were negative, 7.2% were positive, and for 3.4% the result was doubtful. No association between IgG titre and maximum observed level of Legionella occurrence was detected.     

Control of Legionella in hospitals

Legionellas are present in water distribution systems and cooling towers of many hospitals. No firm data are available regarding the need for prophylactic disinfection of these contaminated systems. Disinfection of water systems and cooling towers is an accepted and effective means of ending nosocomial Legionnaires' disease, but it should be performed in conjunction with good epidemiological and microbiological studies to pinpoint environmental reservoirs and disseminators. Chlorination, pasteurization, or both, are the only means of disinfection found to be effective in disease outbreaks. Prospective surveillance of immuno compromised patients with pneumonia is probably the most effective means to determine if a hospital is a source of Legionnaires' disease and, therefore, requires further investigations and disinfection.     

Outsourcing in public hospitals: a Greek perspective

PURPOSE: The purpose of this research is to investigate the extent of outsourcing, the decision-making process, the impact of outsourcing, and the future trend of outsourcing in public hospitals in Greece. DESIGN/METHODOLOGY/APPROACH: A survey instrument was designed and mailed to a random sample of 100 public hospitals in Greece and 43 usable questionnaires were received, representing a response rate of 43 percent. The survey instrument focused on the extent to which public hospitals outsource services, the decision-making process for choosing an external service provider, the impact of outsourcing, and the future trend of outsourcing in public healthcare organisations. FINDINGS: Public hospitals in Greece outsource a variety of activities. Cost savings and customer satisfaction are the main factors affecting the outsourcing decision. The cooperation with a contract service provider has led to significant improvement in service quality levels. Most users are satisfied with the performance of these companies and believe that there will be an increase in the usage of these services in the future. PRACTICAL IMPLICATIONS: It provides a decision-making framework regarding outsourcing in public healthcare organisations. ORIGINALITY/VALUE: This research fills the gap in the area of outsourcing in public hospitals in Greece.     

Negative-Pressure monitoring of tuberculosis isolation rooms within New York State hospitals.

A previously published study recommended the daily use of visible smoke to test for negative air pressure in isolation rooms occupied by potentially infectious tuberculosis cases. Continuous monitoring devices were found to have poor reliability. Findings from our survey of engineering controls in acute-care hospitals within New York State support this recommendation.     

Plan for the control of Legionella infections in long-term care facilities: role of environmental monitoring

In accordance with the international and national guidelines, the Emilia-Romagna Region (Italy) has established regional guidelines for the surveillance and prevention of legionellosis based on the concept of risk assessment, with particular attention to environmental monitoring. The aim of this study was to verify how environmental surveillance in the context of risk assessment plans could help to guide decisions about preventive strategies against Legionella infections in Long Term Care Facilities (LTCF). In six LTCFs in the city of Bologna (Emilia-Romagna Region) a self-control plan was implemented that included the environmental monitoring of Legionella spp. and the surveillance of hospital-acquired Legionnaires' Disease. At baseline, four hot water systems were colonized by Legionella pneumophila (3 LCTFs) and Legionella londiniensis (1 LCTF). In each establishment specific control measures were adopted based on the characteristics of the system, the virulence of the strain and the level of the contamination. The monitoring, carried out for around two years, was also extended to the ways in which the system and the distal water distribution points were used and maintained with respect to the good practices in operation and management. The adopted actions (shock and/or continuous disinfection treatments) and the implementation of the good practice measures reduced the contamination to acceptable and stable levels. No cases of hospital-acquired legionellosis occurred during the period of study. The environmental surveillance was successful in evaluating the risk and identifying the most suitable preventive strategies.     

Quantitative microbial monitoring in a dental office

The aim of this study was to evaluate the environmental pollution before and after dental procedures (during one year) in a dental office in which a system of air filtration was effective and suitable procedures of microbial controls were routinely applied for instruments and small surfaces. The air contamination was evaluated during one year by the 'plate' method (Air Microbial Index, AMI) in each room of the dental office following a bimonthly monitoring program. Nutrient agar plates were exposed, in monitored areas for 1 h for each control time and incubated at 37 degrees C for 2 days. The number of viable cells was expressed as colony forming units per plate per hour (CFU/plate/h). During the observation year, the quantitative analysis of the microbiological levels in the operative areas was always within acceptable values. In fact, a range from 4-18 CFU/plate/h was found as the mean of AMI in each controlled room. In particular, the aerosol pollution following dental procedures did not significantly modify AMI values compared with AMI values recorded before dental procedures. Data presented here demonstrate that the combined use of effective infection control procedures and a system of air filtration can be efficacious in reducing airborne environmental contamination in a dental office and emphasise the use of an inexpensive method such as AMI to verify the environmental bacterial pollution.     

The trend of breast-feeding in a primary child care program

Wakefulness and visual responsiveness were studied in 45 (24 males, 21 females) low medical risk preterms at expected date of birth and 23 (9 males, 14 females) term healthy neonates of the same racial and social background. Three measures of wakefulness and two responsiveness measures were used. Preterms were more wakeful but not more visually responsive than full-term infants. Moreover, on one of the two responsiveness measures preterms did less well than term infants. Intra-measure correlations suggested that the organization of wakefulness and visual responsiveness is different in full-term neonates and in preterms at expected data of birth. Implications of these findings for caregivers' perception of and behavior toward preterms are discussed.

Non-touch fittings in hospitals: a possible source of Pseudomonas aeruginosa and Legionella spp

Deep infection remains a major complication of joint replacement surgery despite advances in theatre design, surgical technique and antibiotic prophylaxis. Major randomized controlled trials to determine the most effective antibiotic prophylaxis are difficult to construct and interpret. In a conventional theatre, most orthopaedic intra-operative wound contamination arrives by the airborne route. This paper describes a unique method used to compare antibiotics against airborne bacteria. Seven antibiotics were incorporated into blood agar at concentrations equivalent to serum levels. Plates were then exposed to airborne theatre bacteria using a multiple synchronous collection technique. After incubation, the percentage kill was calculated for each antibiotic. At concentrations equivalent to serum level 1h post i.v. dose, all the antibiotics proved highly effective, with kill rates > 95%. Imipenem and co-amoxiclav significantly outperformed the other antibiotics with kill rates of 99.6% and 99.4%, respectively. At trough levels, the antibiotics achieved kill rates from 61% to 97.6%. Future randomized controlled trials comparing large numbers of antibiotics in the setting of an already low infection rate are inappropriate. This technique for comparing antibiotic prophylaxis in quick, inexpensive and repeatable. The superiority of imipenem is not unexpected, but of more interest is the effectiveness of co-amoxiclav over the presently favoured cefuroxime.

Wasteful use of financial resources in public hospitals in Turkey: a trend analysis

The Turkish health system is mainly financed by public sources such as taxes and premiums collected from workers. According to 2003 data, total health expenditures were 4.5% of the country's Gross Domestic Product. Currently, 56% of the system is financed by the Ministry of Health, and services are also provided by the Ministry. The main sources of finance among the Ministry of Health hospitals are general budget contributions made by the Ministry and revolving funds. The purpose of this study is to evaluate the financial conditions of those Ministry of Health hospitals that have revolving funds. The financial trends of 2514 hospitals were followed from 1996 to 2000, and financial statement analyses were conducted. The results of the study show that the Ministry of Health hospitals are not professionally administered for their financial situation and also that their financial resources are not used effectively. The hospitals had difficulty in collecting debts and had problems in cash returns. At the end of the study, policy suggestions are made for health care managers toward improving financial conditions in these public hospitals.     

Risk factors for musculoskeletal disorders among nursing personnel in Greek hospitals

OBJECTIVES: To investigate the relationships between physical, psychosocial, and individual characteristics and different endpoints of musculoskeletal complaints of the lower back, neck and shoulders. METHODS: In this cross-sectional study a questionnaire survey was carried out among 351 nursing personnel (response 84%) in six general hospitals in Athens, Greece. A questionnaire was used on physical and psychosocial workload, need for recovery, perceived general health and (1) the occurrence of musculoskeletal complaints in the past 12 months, (2) chronic complaints during at least 3 months, and (3) complaints which led to sickness absence. In logistic regression analysis odds ratios (ORs) were estimated for all relevant risk factors. RESULTS: Self-reported factors of physical load were associated with the occurrence of back pain (OR=1.85), neck pain (OR=1.88), and shoulder pain (OR=1.87) but these factors were not associated with chronic complaints and musculoskeletal sickness absence. Physical load showed a trend with the number of musculoskeletal complaints with ORs of 2.47 and 4.13 for two and three musculoskeletal complaints, respectively. No consistent influence of psychosocial factors on complaints, chronicity, or sickness absence was observed. A perceived moderate general health was also a risk factor, and strongest associations were observed for sickness absence due to back pain (OR=2.03), neck pain (OR=8.31), and shoulder pain (OR=6.84). CONCLUSIONS: The handling of physical loads among nurses seems to put them at risk for the occurrence of musculoskeletal disorders. The development of these complaints into chronic complaints and associated sickness absence is strongly determined by perceived general health and almost not associated with work-related physical and psychosocial risk factors. When the influence of work-related risk factors on musculoskeletal health is being investigated, the general health status of individual workers should be taken into account.
