Costs and management of urinary incontinence in long-term care.

The three aims of the study were (1) to assess the impact and cost of urinary incontinence in long-term care, (2) to determine whether 24-hour incontinence monitoring provides information that improves management, and (3) to ascertain whether costs (nursing time and laundry) could be reduced. The setting was two 24-bed long-term care units in an urban hospital. The research was conducted in three stages. During the initial stage, the impact of incontinence was measured on each unit. Impact was defined as total number of incontinent episodes, nursing time spent changing these patients, and laundry costs, measured during a 7-day period on each unit. After this phase of the investigation, individualized 24-hour incontinence monitoring, followed by recommendations and implementation of care plan, was carried out on one unit. No monitoring or recommendations for care were completed on the other unit, which served as a control. During the third phase of the study, the number of incontinent episodes, nursing time, and laundry costs were again measured on both units. Initially (58%) of residents (24/48) were incontinent, representing 859 episodes of urinary leakage each week that required 45 hours of nursing time to change clothing, containment devices, and bed linens. The direct costs of the nursing time and laundry, expressed in Canadian dollars were $8.60/day per incontinent resident. After 24-hour monitoring of 10 residents one on unit, suggestions were made for various incontinence management programs. An unexpected but simple recommendation was a change to a better containment system for urinary leakage. When impact was measured, a 13% reduction in the number of incontinent episodes was found.(ABSTRACT TRUNCATED AT 250 WORDS)

Hepatic ultrasonic changes in workers exposed to perchloroethylene.

OBJECTIVE: To determine if subclinical hepatotoxicity is associated with exposure to perchloroethylene at concentrations commonly experienced in the workplace, and whether surveillance with serum hepatic transaminase activity underestimates such effects. METHODS: Hepatic parenchymal echogenicity on ultrasonography and serum hepatic transaminase activity were compared in 29 community based dry cleaning operators exposed to perchloroethylene, and a control group of 29 non-exposed laundry workers. Perchloroethylene exposure was assessed by work history and air monitoring. RESULTS: Mean hepatic transaminase activities were minimally increased in dry cleaners compared with laundry workers. Increased alanine aminotransferase activities, between 1.0 and 1.5 times the normal limits, were found in five of 27 (19%) dry cleaners compared with one of 26 (4%) laundry workers. In contrast, diffuse parenchymal changes in echogenicity, as determined by hepatic ultrasonography, were increased nearly twofold in dry cleaners, occurring in 18 of 27 (67%) dry cleaners compared with 10 of 26 (39%) laundry workers (P < 0.05), and were most strongly associated with increased perchloroethylene exposure in older dry to dry or wet transfer operations (odds ratio 4.2, 95% confidence interval 1.1-15.3). Mean eight hour time weighted average perchloroethylene exposure for dry cleaners was 16 ppm, which is less than the permissible exposure limit of 100 ppm in the United States. CONCLUSIONS: It was concluded that mild to moderate hepatic parenchymal changes occur more frequently in workers exposed to perchloroethylene than in populations not exposed to chemical solvents, and that these effects are underestimated by serum hepatic transaminase activity.

Computer provides definite linen distribution and control mechanism.

For the past 10 years or so, large laundries have been concerned with productivity. While productivity has increased 10 to 20 percent, the linen replacement cost in these same laundries has more than doubled. It will not suffice for these laundries to point toward the hospitals they serve and imply that linen service and control is solely a hospital management problem. As long as proven technology is available, these laundries have an inherent responsibility to provide hospital management with the data necessary to pinpoint and correct linen consumption and replacement problems.

[Vertical integration and contracting-out in generic hospital services in Spain].

OBJECTIVES: This study examines the factors that influence make or buy decisions corresponding to four generic services (housekeeping, laundry, food services, and maintenance and security) in Spanish hospitals (3,160 transactions in 790 hospitals). METHODS: The empirical estimation of a logistic model based on hospital utility maximization is presented. Factors included in the model are not only those related to transaction costs, but also those related to public intervention and the political dimension. RESULTS: A total of 55.7% of hospitals contracted-out at least one of the generic services. The services most frequently contracted-out were housekeeping and maintenance and security(45.1 and 32.5%, respectively). In contrast, the services (94.3% and 80.1%, respectively). Hospital size (economies of scale), measured by the number of beds, was one of the most important factors influencing make or buy decisions. CONCLUSIONS: We find evidence that economies of scale are related to a higher level of vertical integration, while specialization and for-profit objectives favor the decision to contract-out. The choice of organizational model for laundry services presents a different pattern from that of the other three services. Empirical results show that some asset specificity could be present in laundry services.

Health promotion in the workplace: the perspective of unskilled workers in a hospital setting.

It is important to explore the potential for health promotion from the perspective of participants in a particular situation. This study focuses on experiences of well-being and the potential for health promotion among unskilled workers in the kitchen and laundry room in an acute care hospital in Iceland. These experiences are analysed in light of the material and structural factors that shape working conditions. The research method used was grounded theory. The data were formal and informal interviews, and participant observation. The findings revealed considerable differences between the two work groups. At both sites strain on the body, caused by excessive noise, heavy lifting and uncomfortable working arrangements, were identified. Similarly, the work was often experienced as monotonous and demanding. Human relations were identified as a key factor in ameliorating the conditions that led to experiences of strain by the workers at both work sites. This was however where the two work places differed. In the laundry room, the workers felt respected and acknowledged by their coworkers and managers. Belonging to the work group was important and they felt listened to by the supervisor. Very little cohesiveness was observed among the workers in the kitchen. The managers seemed to be absent from the floor, workers were divided into work groups that sometimes showed antagonism towards each other and few channels were available for complaints and suggestions for improvement. The workers in the laundry room, on the other hand, related positive experiences of work. They felt that steps were taken by managers to improve working conditions to the extent possible and participated in those attempts by bringing up suggestions, implementing change and developing their own ways of coping with the work. This study gives important directions for health promotion in the workplace, emphasizing human relations at work, rather than individual health behaviour away from the work setting.

Reducing linen usage at the Methodist Hospitals: changing from flat to fitted sheets benefits patients and bottom line.

PROJECT: Reducing waste associated with unnecessary linen use. Principals: Patient care directors from two hospital campuses, manager of the laundry department, and director of environmental services. Process Improvement Method: An organizational change model being applied throughout Methodist Hospitals, based on the work of Dr. Gerard Egan at Loyola University in Chicago. Timeline: Begun: January 1991. RESULTS reported here: August 1991-August 1992. Key Findings or Improvements: The hospital's routine bed-making policies, which called for changing sheets, mattress pads, and bedspreads daily, were wasteful and unnecessary. Patients disliked flat sheets that bunched up, and nurses spent valuable time having to constantly smooth the sheets. Product innovations made fitted sheets, previously rejected, a cost effective alternative. RESULTS: By switching to an "as needed" linen change policy, the Laundry Department received 1,296 fewer pounds of laundry per day and more than 473,000 fewer pounds per year, despite stable occupancy. The resulting cost savings were invested in the improved product (fitted sheets) and a new delivery system (sealed linen packs). Nurses report increased patient comfort from new sheets and reduced nursing time to straighten bunched sheets.

A study of the effect of perchloroethylene exposure on the reproductive outcomes of wives of dry-cleaning workers.

The purpose of this investigation was to compare the reproductive outcomes of wives of men exposed to perchloroethylene in the dry-cleaning industry compared to those of wives of laundry workers. Seventeen female partners of dry cleaners and 32 partners of laundry workers were interviewed. The number of pregnancies and the standardized fertility ratios were similar between the two groups. Wives of dry cleaners did not have higher rates of spontaneous abortions. However, wives of dry cleaners were more than twice as likely to have a history of attempting to become pregnant for more than 12 months or to have sought care for an infertility problem. Cox proportional hazards models indicated that dry-cleaners' wives had half of the per-cycle pregnancy rate of wives of laundry workers, when controlling for other potential confounders (estimated rate ratio of 0.54, 95% C.I. = 0.23, 1.27).

Improving UV protection by clothing--recent developments.

The assessment of UV transmittance of clothing and the determination of the UV protection factor (UPF) are now well established and the influencing factors such as type of fiber, color, and fabric construction are known. Quick and reliable instruments to measure UV transmittance are crucial. Besides expensive scientific laboratory instruments, a low-cost UV meter is now available for this purpose. The questions arise as to what can be done about a given garment and whether there are ways to improve textiles by the consumer. The many opportunities to improve UV protection of clothing along the textile chain of manufacturing are discussed. The latest possibility for improving the UV-protective properties of clothing is now available at the fabric care stage in every household. A UV absorber can be brought into contact with a fabric during the wash or rinse cycle of a laundry operation. The high UV transmittance of 30% of a thin, bleached cotton swatch in the dry state (UPF 3), can be reduced tenfold to about 3% (UPF >30) in ten washes cycles. This is more than the effect achieved by dyestuffs. The detergent should contain about 0.1-0.3% of the special UV absorber. The same effect can be achieved as early as after one wash cycle with a higher concentration provided by a special laundry additive. Yet another form of application is via rinse cycle fabric conditioner. To make these new types of improvement of fabrics visible the Skin Cancer Foundation now provides the possibility for laundry products to qualify for the "Seal of Recommendation".

Comparative assessment of the acute skin irritation potential of detergent formulations using a novel human 4-h patch test method.

Predictive skin irritation test methods, which do not require use of animals, are needed for the pre-market assessment of detergent formulations. The utility of a novel and ethical human acute skin irritation patch test method, originally developed for chemical skin irritation assessment, was evaluated. In this IRB-approved method, subjects were patched under occlusion for increasing periods of time up to 4h in duration. The total incidence of positive skin reactions for test products was compared to a positive control (20% aqueous sodium dodecyl sulfate [SDS]). Acutely irritating formulas were defined as those showing a significantly increased or equal incidence of positive responders compared with that of SDS. The time of exposure required for 50% of subjects to show a positive skin reaction (TR50 value) was calculated for each product and enabled test product comparisons within and between studies. Using this approach, 24 detergent formulations of various types were tested in seven individual studies. The skin irritation profiles were generally consistent within product types, which could be categorized as follows (by decreasing irritancy): mold/mildew removers (average TR50 = 0.37 h) > disinfectants/sanitizers (0.64 h) > fabric softener concentrate (1.09 h) = aluminum wash (1.20 h) > 20% SDS (1.81 h) > liquid laundry detergents (3.48 h) > liquid dish detergents (4.16 h) = liquid fabric softeners (4.56 h) = liquid hand soaps (4.58 h) = shampoos (5.40 h) = hard surface cleaners (6.34 h) > powder automatic dish detergents (>16 h) = powder laundry detergents (>16 h). In addition to formulation effects, some seasonal effects were noted; particularly greater winter-time reactivity to 20% SDS and the hard surface cleaner and liquid laundry formulations. These results demonstrate the utility of this patch test method for the comparative skin irritation assessment of these different product types.

How clean is clean enough? Maintaining thermal protective clothing under field conditions in the oil and gas sector.

The purpose of this research was to develop practical care procedures to help maintain the protective quality of flame resistant workwear laundered by workers in the field. Based on observed field conditions, experiments were conducted that simulated domestic laundry procedures. The first experiment involved two flame resistant (FR) fabrics, contaminated or not contaminated with oil. Independent variables also included detergent type and laundry pre-treatment. Other laundry parameters were controlled. Results indicated that it is easier to maintain the FR performance of the FR-treated blend than it is for the aramid fabric. It is hypothesized that energy generated by initial ignition of oil on the specimens triggers the FR mechanism of the treatment, which in turn inhibits further combustion. A second experiment using larger specimens and a domestic washing machine also supported the hypothesized mechanism.

Sanitation in self-service automatic washers.

The potential for microbial transfer in self-service laundry washing machines was investigated by obtaining swab samples from the interior surfaces of commercial machines and wash water samples before and after disinfectant treatment. Three disinfectants (chlorine, a quaternary ammonium product, and a phenolic disinfectant) were used. Four self-service laundry facilities were sampled, with 10 replications of the procedure for each treatment at each location. Although washers were set on a warmwater setting, the wash water temperatures ranged from 24 to 51 degrees C. The quaternary ammonium product seemed most effective, averaging a 97% microbial kill; chlorine was the second most effective, with a 58% kill, and the phenolic disinfectant was least effective, with only a 25% kill. The efficacies of the chlorine and phenolic disinfectants were reduced at low water temperatures commonly experienced in self-service laundries. Interfamily cross-contamination in self-service facilities is a potential public health problem, which is aggravated by environmental conditions, such as water temperature and the practices of the previous users of the equipment. Procedural changes in laundering are recommended, including the use of a disinfectant to maintain adequate levels of sanitation.

Laundering in the prevention of skin infections.

The statistics at the Hohenstein Institutes and the detergent industry show that the number of complaints due to skin irritations or allergies of washed laundry are relatively low. A clear interdependence between the number of complaints and the season of the year is existing. An interesting fact is that work wear made of cotton shows a relatively higher number of complaints than blends of polyester with cotton. The highest number of complaints results from operating theatre textiles, which is probably due to the exceptional strain of the skin of the operating-theatre staff by surgical disinfecting measures. During washing in household washing machines and also in the industrial sector it is mainly the mechanical action of the washing machines and the chemistry of the detergents which influence the textiles. The effects of the washing process on the textiles if assessed regarding the dermatological point of view, can go in two different directions: Changes of the textile itself and the formation of residues on the washed laundry, whereby the residues can be unintended, i.e. inevitable or desired, so to speak as finishing, for example optical brighteners, softeners, etc. The changes of the textile substance itself can result in a raising. This can either mean that the textile becomes more harsh in feel or fluffier. Textiles which become harsher only have little influence on the skin. Whereas the change to a fluffier textile has positive effects on the skin as there are so-called 'distance holders' formed on the textile surface, which prevents an early sticking of the textiles to a perspirating skin. This increases the wear comfort. Inevitable residues on the washed laundry can be caused by wear (this is not important), the washing water and the detergent. Within the detergents only the surfactants and alkalines are of interest. Desired residues are for example optical brighteners to increase the degree of whiteness, softeners, finishing baths (starch), scents and water-repellent finishes. Regarding special cases like for example flame-retardant finishes, antistatic additives and antimicrobial effects, there is only little experience available so far.

Evaluation of the effect of energy conservation techniques in the performance of activity of daily living tasks.

OBJECTIVE: To determine whether energy conservation techniques during common activity of daily living tasks actually result in lower energy expenditure, and to document subjective comments regarding any differences in the perceived level of effort. DESIGN: Descriptive study comparing energy expenditure in three tasks with and without energy conservation techniques, taking into account the effect of age. SETTING: Occupational therapy department of a rehabilitation hospital in Hong Kong. SUBJECTS: One hundred and eight subjects (30 < 60 years; 78 > or = 60 years) were recruited from staff and members of an elderly social centre in the community. MEASUREMENTS: Energy expenditure was measured using a portable indirect calorimetry system for three tasks (shopping, washing clothes and hanging laundry) with and without energy conservation techniques. Dyspnoea, fatigue and perceived exertion were measured using visual analogue scales. RESULTS: Reduction in energy expenditure using energy conservation techniques for shopping and hanging laundry was documented in younger subjects only (O2 consumption fell from 13.8 +/- 3.7 to 12.2 +/- 3.8 mL/min per kg for shopping, P < 0.001 and 5.9 +/- 1.2 to 5.0 -/+ 1.2 mL/min per kg, P < 0.001 for hanging laundry), although the older subjects experienced less perceived exertion with the energy conservation techniques. For washing clothes, no reduction in energy expenditure was observed in either age groups. CONCLUSION: Measurable benefits were observed with use of labour-saving equipment and avoidance of overhead reaching in younger subjects only.

Odors and the perception of hygiene.

Although certain odors, such as lemon, are commonly associated with cleanliness and positive hygiene, empirical assessment of such associations for other odors and attributes is generally lacking. Moreover, differences between men and women in such associations have not been established. In this study of lemon, onion, pine, and smoke odors, ratings were obtained from 142 men and 336 women (M age= 30.1 yr., SD = 12.3) for odor intensity, gender association (masculine/feminine), and the success, sociability, intelligence, cleanliness, and attractiveness of a hypothetical person whose clothes smell like the odor in question. Ratings of the pleasantness or unpleasantness one would attribute to each odor in various rooms of the home were obtained, as well as a specification of whether such ratings are influenced by laundry habits, e.g., whether laundry is smelled before or after washing. Numerous associations were found. For example, a hypothetical person whose clothes smell of pine was rated as relatively more successful, intelligent, sociable, sanitary, and attractive than one whose clothes smelled of lemon, onion, or smoke. Sex differences, as well as differences between people who reported smelling their own laundry, were also found.

Effects of surfactants originating from reuse of greywater on capillary rise in the soil.

Greywater is all domestic wastewater excluding toilet effluents. Detergents contain surfactants, which account for the highest concentration of organic chemicals in average domestic wastewater. Accumulation of surfactants in greywater-irrigated soils was determined in three household gardens. The effect of surfactants on capillary rise in loess and sand was then tested in the range of concentrations found in the garden soils. The capillary rise of freshwater in sieved oven-dried soil mixed with different concentrations of laundry detergent solution (10% w/w moisture content) was determined. In a second setup, the soil was mixed with freshwater and the rising solution contained different concentrations of detergent solution. The introduction of laundry solution to the soils caused a significant decrease in the capillary rise over the range of concentrations that is found in greywater-irrigated soils. The effect was more noticeable in the sand than in the loess. Interestingly, in the second setup, the capillary rise of the laundry solutions in the sand was almost similar to that of freshwater, whereas in the loess the capillary rise was significantly reduced. It is suggested that accumulation of surfactants in the soil might form water repellent soils that have a significant effect on agricultural productivity and environmental sustainability.

Serious respiratory consequences of detergent ingestions in children.

After ingesting or inhaling laundry detergent powder, eight children required hospital admission. The predominant symptoms were stridor, drooling, and respiratory distress. All but one patient underwent endoscopy of the airways and the esophagus, five children were admitted to the intensive care unit, and four children required endotracheal intubation. Laundry detergent ingestions are generally considered to have minor consequences, and there exists a paucity of literature on the subject. Evidence of significant morbidity incurred because of ingestion or inhalation of sodium carbonate-containing laundry detergent powder is presented, together with a review of the existing literature.

Update on clinical attire requirements in dental hygiene programs.

PURPOSE: Many changes have occurred in the clinical appearance of dental hygienists in the past few years because of increased emphasis on infection control and disease prevention. The purpose of this study was to assess dental hygiene program clinical attire requirements in 1993 and to compare them with requirements as described by a 1988 survey. METHODS: Checklist questionnaires were mailed to the directors of all 211 dental hygiene programs in the United States and Puerto Rico in October 1993. Questions were asked regarding clinical attire requirements for students and faculty, including uniforms, gowns, lab coats, masks, protective eyewear, shoes, hair coverings, laundry management, and changes under consideration. Percentages were calculated by region and for all responding programs. RESULTS: Of 211 questionnaires mailed, 178 were returned, for a response rate of 84%. Results indicated that students and faculty are currently wearing more colorful uniforms and scrubs than in 1988. Long-sleeved lab coats, disposable gowns, and washable surgical gowns are increasing in use. Glasses and face masks were required for all students and faculty in both surveys, but chin-length face shields are increasing in use as optional face protection. In most instances, face shields are worn with face masks. Laundry services are being provided for faculty (employees); however, most students continue to be responsible for their own laundry after being instructed to follow stringent guidelines taught by the faculty. CONCLUSIONS: Increasing emphasis on personal and patient protection is moving clinical attire requirements toward a more surgical appearance. Dental hygiene educators continue to monitor and to stay current with federal infection control recommendations, regulations, and guidelines.

Streptokinase versus alteplase and other treatments for acute and delayed thrombolysis of blood stains in clothing.

OBJECTIVE: To assess the usefulness of heparin, alteplase, and streptokinase in removing blood stains. DESIGN: Randomised controlled trial. SETTING: Hospital laundry. INTERVENTIONS: Blood stains were allocated to treatment with alteplase, streptokinase, heparin, a commercial enzymatic stain remover, or no treatment at all after three or seven hours and then washed in hot or cold water two hours later. RESULTS: Both hot water and early treatment were strongly associated with improved stain removal. All four treatments were associated with a worse outcome than no treatment at all, although for streptokinase this trend did not reach significance. The commercial stain remover gave the worst results of all treatments tested. CONCLUSIONS: Contrary to popular wisdom, hot water is much more effective than cold in removing blood stains. Methodologically rigorous research and evidence based principles are needed within the laundry industry, and the role of thrombolytic drugs should be assessed further.
