Double-blind, randomized trial of scheduled use of a novel barrier cream and an oil-containing lotion for protecting the hands of health care workers

Chronic Hand Eczema (CHE): A Narrative Review

Chronic hand eczema (CHE) is a common and challenging skin condition, characterized by persistent hand dermatitis which lasts over 3 months or recurs at least twice a year. This condition is often multifactorial, involving genetic predispositions, environmental factors and triggers, such as irritants and allergens. Studies show a higher incidence in women, though prevalence estimates vary across different age groups. The pathogenesis involves complex immune mechanisms, particularly Th1/Th2 cell responses. Clinically, CHE presents in various forms, with symptoms such as redness, scaling and itching that significantly impact patients' quality of life. Treatment approaches are diverse. While emollients and topical corticosteroids have historically been the mainstay, new systemic therapies like JAK inhibitors and biologics are progressively being used for severe cases. Key molecular targets comprise interleukin (IL)-4 and IL-13, the JAK-STAT pathway, phosphodiesterase 4 (PDE4) and chemoattractant chemokines. Managing CHE effectively remains a challenge because of its chronicity and the variability in individual responses to treatment. However, emerging therapeutic strategies will help clinicians to offer more patient-centred approaches.

Chronic Hand Eczema

Chronic hand eczema (CHE) is a complex, challenging, and frequently multifactorial skin disease of the hands. It is very common in the general population, especially in certain professions. When hand eczema (HE) persists for longer than 3 months or has a minimum of two relapses per year after initial manifestation with complete clearance, it is considered chronic. In this case, health-related quality of life and the patient's working life are often impaired. CHE can be considered as an umbrella term because it covers different clinical pictures and etiologies. To date, there is no definite and unique HE classification. Treatment starts with identifying the individual HE etiology paralleled by symptomatic therapy (local and/or systemic and/or ultraviolet phototherapy). Sustainable management of HE requires the identification and avoidance of its triggering factors, from the professional and private environment. This includes ruling out allergic contact dermatitis if any HE persists for more than 3 months despite adequate therapy. Randomized controlled trials investigating the efficacy in HE are lacking for several treatment modalities. Patient education measures of skin protection and prevention complete the multimodal treatment.

S2k-Leitlinie Diagnostik, Prävention und Therapie des Handekzems: S2k guideline diagnosis, prevention and therapy of hand eczema

Die S2k‐Leitlinie „Diagnostik, Prävention und Therapie des Handekzems (HE)“ gibt auf der Grundlage eines evidenz‐ und konsensbasierten Ansatzes konkrete Handlungsanweisungen und Empfehlungen für die Diagnostik, Prävention und Therapie des HE. Die Leitlinie wurde auf der Grundlage der deutschen Leitlinie „Management von Handekzemen“ aus dem Jahr 2009 und der aktuellen Leitlinie der European Society of Contact Dermatitis (ESCD) „Guidelines for diagnosis, prevention and treatment of hand eczema“ aus dem Jahr 2022 erstellt. Allgemeines Ziel der Leitlinie ist es, Dermatologen und Allergologen in der Praxis und Klinik eine akzeptierte, evidenzbasierte Entscheidungshilfe für die Auswahl sowie Durchführung einer geeigneten und suffizienten Therapie für Patienten mit Handekzemen zur Verfügung zu stellen. Die Leitlinie basiert auf zwei Cochrane‐Reviews zu therapeutischen und präventiven Interventionen beim HE. Die übrigen Kapitel wurden überwiegend basierend auf nicht systematischen Literaturrecherchen durch die Expertengruppe erarbeitet und konsentiert. Die Expertenkommission bestand aus Mitgliedern von allergologischen und berufsdermatologischen Fachgesellschaften und Arbeitsgruppen, einer Patientenvertretung und Methodikern. Im Rahmen einer Konsensuskonferenz am 15.09.2022 wurden die Vorschläge für die Empfehlungen und Kernaussagen unter Verwendung eines nominalen Gruppenprozesses konsentiert. Der strukturierte Konsensfindungsprozess wurde professionell moderiert. Die vorliegende Leitlinie hat eine Gültigkeit bis zum 22.02.2028.

S2k guideline diagnosis, prevention, and therapy of hand eczema

The consensus-based guideline "Diagnosis, prevention, and treatment of hand eczema (HE)" provides concrete instructions and recommendations for diagnosis, prevention, and therapy of HE based on an evidence- and consensus-based approach. The guideline was created based on the German guideline "Management von Handekzemen" from 2009 and the current guideline of the European Society of Contact Dermatitis (ESCD) "Guidelines for diagnosis, prevention, and treatment of hand eczema" from 2022. The general goal of the guideline is to provide dermatologists and allergologists in practice and clinics with an accepted, evidence-based decision-making tool for selecting and conducting suitable and sufficient therapy for patients with hand eczema. The guideline is based on two Cochrane reviews of therapeutic and preventive interventions for HE. The remaining chapters were mainly developed and consented based on non-systematic literature research by the expert group. The expert group consisted of members of allergological and occupational dermatological professional associations and working groups, a patient representative, and methodologists. The proposals for recommendations and key statements were consented by using a nominal group process during a consensus conference on September 15, 2022. The structured consensus-building process was professionally moderated. This guideline is valid until February 22, 2028.

Retrospective evaluation of the effectiveness of using two different products in preventing the development of pressure injuries in patients undergoing lung lobectomy

AIM

This retrospective study aims to determine the impacts of two different products (barrier cream, barrier spray) routinely used before surgery on the development of postoperative pressure injuries in patients undergoing lung lobectomy.

MATERIALS AND METHODS

In the study, the researchers retrospectively examined the data of 60 patients who underwent lobectomy in a university hospital's thoracic surgery clinic between 12.02.2021 and 14.02.2022. The patients were divided into two groups: those to whom a barrier cream was applied (30) and those to whom a barrier spray was applied. The Patient Description Form and the Braden Risk Assessment Tool were used in data collection. The Mann-Whitney U and Kruskal-Wallis tests were conducted for statistical analyses.

RESULTS

In the study, the development rates of blanchable erythema and stage I pressure injuries in the sacral and dorsal regions were significantly higher in patients to whom a barrier spray was applied than in patients to whom a barrier cream was applied (p < 0.05). Pain intensity in the sacral and dorsal regions was significantly lower in patients to whom a barrier cream was applied than those to whom a barrier spray was applied (p < 0.05).

CONCLUSION

Blanchable erythema and intraoperative pressure injury were observed less in patients in whom a barrier cream was used before surgery. Surgical nurses should first evaluate the risk in the preoperative period in the clinics and benefit from the use of barrier cream to prevent the development of blanchable erythema and intraoperative pressure injury.

Evaluation of the Cytotoxicity of Various Hand Disinfectants and Ozonated Water to Human Keratinocytes in a Cultured Epidermal Model

OBJECTIVE

To evaluate the cytotoxicity of various hand disinfectants and ozonated water to human keratinocytes using a cultured epidermal model.

DESIGN

Using a test protocol from the Organization for Economic Co-operation and Development, investigators applied hand disinfectants containing either 83% ethanol, 0.2% benzalkonium chloride, 0.5% povidone-iodine, 1% chlorhexidine, 1% chlorhexidine ethanol, or ozonated water to a cultured human epidermal model. Surface morphology and histologic changes were evaluated by scanning electron microscopy and hematoxylin-eosin staining.

MAIN OUTCOME MEASURES

Production of inflammatory cytokine interleukin 1α by keratinocytes and cell death rate.

MAIN RESULTS

Electron microscopic analysis revealed the creation of small holes on the stratum corneum, and hematoxylin-eosin staining revealed perinuclear vacuolation of keratinocytes and cells with a condensed nucleus. Interleukin 1α was detected in the culture supernatants. More than 80% of keratinocytes did not survive after a 15-minute application of disinfectants. However, no significant damage was detected with ozonated water.

CONCLUSIONS

Ozonated water did far less damage to keratinocytes than the tested disinfectants. Although the ability of ozonated water to disinfect hands of medical staff members requires further study, it might serve as an alternative with minimum cytotoxicity.

Impact of daily wearing of fabric gloves on the management of hand eczema: A pilot study in health-care workers

Hand eczema is a major occupational disease, especially in medical workers, reducing their quality of life (QOL) and work productivity. Daily wearing of fabric gloves to prevent loss of moisture and lipids from the surface of the hands has been regarded as good in the management of hand eczema. However, limited evidence is available regarding the efficacy of moisturizing care with daily gloves on hand eczema. This pilot study was performed to evaluate the efficacy of moisturizing intervention with daily wearing of fabric gloves on skin barrier function, disease severity, and microbiome in health-care workers with hand eczema. Study 1: Nurses in the neonatal intensive care unit or growing care unit with and without hand eczema were recruited in the study. Subjects were instructed to apply moisturizer and wear two types of fabric gloves, common cotton gloves and moisturizing fabric gloves containing malate, for 4 weeks. Study 2: Physicians and health-care workers were recruited and instructed to wear a cotton glove on one hand at nighttime for 4 weeks. Disease severity, skin barrier function, QOL, and hand microbiome (Study 1) were evaluated. Study 1 found that daily wearing of both types of fabric gloves accompanied by use of topical moisturizers reduced the severity of hand eczema without changing the variation of microbiome. Study 2 found no apparent change between wearing and not wearing cotton gloves. In summary, topical moisturizer is of fundamental importance, and concomitant use of fabric gloves may merely enhance the efficacy of moisturizer in the management of hand eczema.

Preventing adverse cutaneous reactions from amplified hygiene practices during the COVID-19 pandemic: how dermatologists can help through anticipatory guidance

The COVID-19 pandemic has swept the globe with more than 2,000,000 confirmed cases of SARS-CoV-2 infection in 184 countries and territories. According to the Centers for Disease Control and Prevention (CDC), two crucial actions can reduce the risk of person-to-person viral transmission: frequent hand washing and surface decontamination with specific environmental protection agency (EPA)-registered disinfectants. As hygiene recommendations evolve during the COVID-19 pandemic and community members adopt changing practices, dermatologists are likely to see a rise in adverse cutaneous reactions from prolonged irritant exposures and widespread use of antimicrobials. The purposes of this report are to familiarize dermatologists with the hygiene practices recommended for COVID-19 prevention, to highlight adverse cutaneous reactions associated with repeated exposures to detergents and disinfectants, and to discuss strategies which patients can implement during the COVID-19 pandemic to minimize skin irritation white still performing hygiene practices effectively.

A behaviour change package to prevent hand dermatitis in nurses working in health care: the SCIN cluster RCT

BACKGROUND

Although strategies have been developed to minimise the risk of occupational hand dermatitis in nurses, their clinical effectiveness and cost-effectiveness remain unclear.

OBJECTIVES

The Skin Care Intervention in Nurses trial tested the hypothesis that a behaviour change package intervention, coupled with provision of hand moisturisers, could reduce the point prevalence of hand dermatitis when compared with standard care among nurses working in the NHS. The secondary aim was to assess the impact of the intervention on participants' beliefs and behaviour regarding hand care, and the cost-effectiveness of the intervention in comparison with normal care.

DESIGN

Cluster randomised controlled trial.

SETTING

Thirty-five NHS hospital trusts/health boards/universities.

PARTICIPANTS

First-year student nurses with a history of atopic tendency, and full-time intensive care unit nurses.

INTERVENTION

Sites were randomly allocated to be 'intervention plus' or 'intervention light'. Participants at 'intervention plus' sites received access to a bespoke online behaviour change package intervention, coupled with personal supplies of moisturising cream (student nurses) and optimal availability of moisturising cream (intensive care unit nurses). Nurses at 'intervention light' sites received usual care, including a dermatitis prevention leaflet.

MAIN OUTCOME MEASURE

The difference between intervention plus and intervention light sites in the change of point prevalence of visible hand dermatitis was measured from images taken at baseline and at follow-up.

RANDOMISATION

Fourteen sites were randomised to the intervention plus arm, and 21 sites were randomised to the intervention light arm.

BLINDING

The participants, trial statistician, methodologist and the dermatologists interpreting the hand photographs were blinded to intervention assignment.

NUMBERS ANALYSED

An intention-to-treat analysis was conducted on data from 845 student nurses and 1111 intensive care unit nurses.

RESULTS

The intention-to-treat analysis showed no evidence that the risk of developing dermatitis was greater in the intervention light group than in the intervention plus group (student nurses: odds ratio 1.25, 95% confidence interval 0.59 to 2.69; intensive care unit nurses: odds ratio 1.41, 95% confidence interval 0.81 to 2.44). Both groups had high levels of baseline beliefs about the benefits of using hand moisturisers before, during and after work. The frequency of use of hand moisturisers before, during and after shifts was significantly higher in the intensive care unit nurses in the intervention plus arm at follow-up than in the comparator group nurses. For student nurses, the intervention plus group mean costs were £2 lower than those for the comparator and 0.00002 more quality-adjusted life-years were gained. For intensive care unit nurses, costs were £4 higher and 0.0016 fewer quality-adjusted life-years were gained.

HARMS

No adverse events were reported.

LIMITATIONS

Only 44.5% of participants in the intervention plus arm accessed the behaviour change package.

CONCLUSION

The intervention did not result in a statistically significant decrease in the prevalence of hand dermatitis in the intervention plus group.

FUTURE WORK

Participants had a high level of baseline beliefs about the importance of using hand moisturisers before, during and after work. Future research should focus on how workplace culture can be changed in order for that knowledge to be actioned.

A novel dermo-cosmetic product containing thermal spring water, sucralfate, copper sulfate, and zinc sulfate in the management of hand eczema

Background

The regular use of cosmetic products plays a role in the management of hand eczema (HE) and aids in improving barrier function reducing dryness, roughness, pruritus and improving quality of life (QoL). The aim of this open-label study was to assess the efficacy and the reparative effect of a dermo-cosmetic product on subjects suffering from HE after 7 and 21 days of daily application.

Methods

The product was a water-in-oil (W/O) emulsion containing the active ingredients Avène thermal spring water, sucralfate, and copper and zinc sulfates. In total, 32 subjects suffering from either contact dermatitis or climatic dermatitis participated in the trial. The modified total lesion symptom score and physician global assessment scores were used to describe the severity of HE. The safety of the product was assessed through clinical scoring. The subjective tolerance, and acceptance, were documented using a self-assessment questionnaire completed by the subjects. The impact of the dermatosis on QoL was evaluated using the Dermatology Life Quality Index.

Results

After 7 days of application, both the physician and subjects noticed a significant improvement in HE. The formula was very well tolerated and accepted. These benefits were correlated with a significant improvement in QoL.

Conclusion

The W/O emulsion used in this study demonstrated real benefits for the subjects suffering from contact dermatitis and climatic dermatitis.

Interventions for preventing occupational irritant hand dermatitis

BACKGROUND

Occupational irritant hand dermatitis (OIHD) causes significant functional impairment, disruption of work, and discomfort in the working population. Different preventive measures such as protective gloves, barrier creams and moisturisers can be used, but it is not clear how effective these are. This is an update of a Cochrane review which was previously published in 2010.

OBJECTIVES

To assess the effects of primary preventive interventions and strategies (physical and behavioural) for preventing OIHD in healthy people (who have no hand dermatitis) who work in occupations where the skin is at risk of damage due to contact with water, detergents, chemicals or other irritants, or from wearing gloves.

SEARCH METHODS

We updated our searches of the following databases to January 2018: the Cochrane Skin Specialised Register, CENTRAL, MEDLlNE, and Embase. We also searched five trials registers and checked the bibliographies of included studies for further references to relevant trials. We handsearched two sets of conference proceedings.

SELECTION CRITERIA

We included parallel and cross-over randomised controlled trials (RCTs) which examined the effectiveness of barrier creams, moisturisers, gloves, or educational interventions compared to no intervention for the primary prevention of OIHD under field conditions.

DATA COLLECTION AND ANALYSIS

We used the standard methodological procedures expected by Cochrane. The primary outcomes were signs and symptoms of OIHD developed during the trials, and the frequency of treatment discontinuation due to adverse effects.

MAIN RESULTS

We included nine RCTs involving 2888 participants without occupational irritant hand dermatitis (OIHD) at baseline. Six studies, including 1533 participants, investigated the effects of barrier creams, moisturisers, or both. Three studies, including 1355 participants, assessed the effectiveness of skin protection education on the prevention of OIHD. No studies were eligible that investigated the effects of protective gloves. Among each type of intervention, there was heterogeneity concerning the criteria for assessing signs and symptoms of OIHD, the products, and the occupations. Selection bias, performance bias, and reporting bias were generally unclear across all studies. The risk of detection bias was low in five studies and high in one study. The risk of other biases was low in four studies and high in two studies.The eligible trials involved a variety of participants, including: metal workers exposed to cutting fluids, dye and print factory workers, gut cleaners in swine slaughterhouses, cleaners and kitchen workers, nurse apprentices, hospital employees handling irritants, and hairdressing apprentices. All studies were undertaken at the respective work places. Study duration ranged from four weeks to three years. The participants' ages ranged from 16 to 67 years.Meta-analyses for barrier creams, moisturisers, a combination of both barrier creams and moisturisers, or skin protection education showed imprecise effects favouring the intervention. Twenty-nine per cent of participants who applied barrier creams developed signs of OIHD, compared to 33% of the controls, so the risk may be slightly reduced with this measure (risk ratio (RR) 0.87, 95% confidence interval (CI) 0.72 to 1.06; 999 participants; 4 studies; low-quality evidence). However, this risk reduction may not be clinically important. There may be a clinically important protective effect with the use of moisturisers: in the intervention groups, 13% of participants developed symptoms of OIHD compared to 19% of the controls (RR 0.71, 95% CI 0.46 to 1.09; 507 participants; 3 studies; low-quality evidence). Likewise, there may be a clinically important protective effect from using a combination of barrier creams and moisturisers: 8% of participants in the intervention group developed signs of OIHD, compared to 13% of the controls (RR 0.68, 95% CI 0.33 to 1.42; 474 participants; 2 studies; low-quality evidence). We are uncertain whether skin protection education reduces the risk of developing signs of OIHD (RR 0.76, 95% CI 0.54 to 1.08; 1355 participants; 3 studies; very low-quality evidence). Twenty-one per cent of participants who received skin protection education developed signs of OIHD, compared to 28% of the controls.None of the studies addressed the frequency of treatment discontinuation due to adverse effects of the products directly. However, in three studies of barrier creams, the reasons for withdrawal from the studies were unrelated to adverse effects. Likewise, in one study of moisturisers plus barrier creams, and in one study of skin protection education, reasons for dropout were unrelated to adverse effects. The remaining studies (one to two in each comparison) reported dropouts without stating how many of them may have been due to adverse reactions to the interventions. We judged the quality of this evidence as moderate, due to the indirectness of the results. The investigated interventions to prevent OIHD probably cause few or no serious adverse effects.

AUTHORS' CONCLUSIONS

Moisturisers used alone or in combination with barrier creams may result in a clinically important protective effect, either in the long- or short-term, for the primary prevention of OIHD. Barrier creams alone may have slight protective effect, but this does not appear to be clinically important. The results for all of these comparisons were imprecise, and the low quality of the evidence means that our confidence in the effect estimates is limited. For skin protection education, the results varied substantially across the trials, the effect was imprecise, and the pooled risk reduction was not large enough to be clinically important. The very low quality of the evidence means that we are unsure as to whether skin protection education reduces the risk of developing OIHD. The interventions probably cause few or no serious adverse effects.We conclude that at present there is insufficient evidence to confidently assess the effectiveness of interventions used in the primary prevention of OIHD. This does not necessarily mean that current measures are ineffective. Even though the update of this review included larger studies of reasonable quality, there is still a need for trials which apply standardised measures for the detection of OIHD in order to determine the effectiveness of the different prevention strategies.

Quantifying the Effects of Water Temperature, Soap Volume, Lather Time, and Antimicrobial Soap as Variables in the Removal of Escherichia coli ATCC 11229 from Hands

The literature on hand washing, while extensive, often contains conflicting data, and key variables are only superficially studied or not studied at all. Some hand washing recommendations are made without scientific support, and agreement between recommendations is limited. The influence of key variables such as soap volume, lather time, water temperature, and product formulation on hand washing efficacy was investigated in the present study. Baseline conditions were 1 mL of a bland (nonantimicrobial) soap, a 5-s lather time, and 38°C (100°F) water temperature. A nonpathogenic strain of Escherichia coli (ATCC 11229) was the challenge microorganism. Twenty volunteers (10 men and 10 women) participated in the study, and each test condition had 20 replicates. An antimicrobial soap formulation (1% chloroxylenol) was not significantly more effective than the bland soap for removing E. coli under a variety of test conditions. Overall, the mean reduction was 1.94 log CFU (range, 1.83 to 2.10 log CFU) with the antimicrobial soap and 2.22 log CFU (range, 1.91 to 2.54 log CFU) with the bland soap. Overall, lather time significantly influenced efficacy in one scenario, in which a 0.5-log greater reduction was observed after 20 s with bland soap compared with the baseline wash (P = 0.020). Water temperature as high as 38°C (100°F) and as low as 15°C (60°F) did not have a significant effect on the reduction of bacteria during hand washing; however, the energy usage differed between these temperatures. No significant differences were observed in mean log reductions experienced by men and women (both 2.08 log CFU; P = 0.988). A large part of the variability in the data was associated with the behaviors of the volunteers. Understanding what behaviors and human factors most influence hand washing may help researchers find techniques to optimize the effectiveness of hand washing.

Management of Chronic Hand Eczema

Management of hand eczema is complex because of the broad range of different pathogeneses, courses, and prognoses. Furthermore, the efficacy of most available treatments is not well established and the more severe forms can have a major impact on the patient's quality of life. Patient education, preventive measures, and the use of emollients are the mainstays in the management of hand eczema. High-potency topical corticosteroids are the treatment of choice, with calcineurin inhibitors used for maintenance. Phototherapy or systemic treatments are indicated in patients who do not respond to topical treatments. Switching from topical treatments should not be delayed to avoid sensitizations, time off work, and a negative impact on quality of life. Alitretinoin is the only oral treatment approved for use in chronic hand eczema.

A controlled laboratory comparison of 4 topical skin creams moisturizing capability on human subjects

PURPOSE

This study compares human skin capacitance (moisture) readings after the application of 4 different, commercially available, topical skin creams.

SUBJECTS AND SETTING

Twenty-one subjects (15 women and 6 men) aged 49.38 ± 11.02) years (mean ± SD) participated. This study was conducted in a climate-controlled laboratory on healthy human subjects.

DESIGN

Randomized experimental study comparing 4 topical skin creams for their effect on human skin capacitance (moisture).

METHODS

Subject forearm skin was conditioned for 7 days prior to testing by washing with a standard soap and application of no other products. Each subject was marked with 5 test sites on the forearms. Sites on the volar surface of each subject's forearms were randomly assigned for application of 1 of 4 product pairs, consisting of a cleanser and a topical skin cream or a control site. A Corneometer was used to measure skin capacitance. Each site on the arms was cleaned and dried, tested again for moisture content, subjected to topical skin cream application, and finally tested again for moisture content. Changes were measured by subtracting the capacitance readings at baseline from values measured following topical skin cream application for each test site.

RESULTS

The mean change in capacitance was 13.9 for product 1, 10.3 for product 3, 8.7 for product 2, 1.6 for product 4, and 0.8 for the control site. The mean capacitance change in sites treated with product 1 (13.9 ± 8.0, mean ± SD) was significantly greater than all others. There was no difference between the change in capacitance of product 2 (mean = 8.7, SD = 4.9) and product 3 (10.3 ± 7.1) t(20) = 1.081, P = .293, nor between product 4 (1.6 ± 3.9) and the control site (0.3, ± 2.2) t(20) = 0.779, P = .445. The capacitance change of products 2 and 3 was greater than that of product 4 and the control site.

CONCLUSIONS

Commercially available topical skin creams vary in their impact on human skin capacitance. In this study, sites tested with product 1 had a greater skin capacitance reading than the other tested products; products 2 and 3 had similar capacitance readings. The results of this study provide an initial evaluation of topical skin creams that have varying impacts on skin capacitance.

Hand hygiene practices among community Health Officers in Rivers State, Nigeria

BACKGROUND

Health care associated infections are most commonly transmitted by the hands of Health care workers and other hospital personnel.

OBJECTIVE

To investigate compliance with hand hygiene guidelines and methods of hand hygiene practice among community health officers in Rivers State Nigeria.

METHODS

Self administered questionnaires were distributed to 68 community health officers. The questionnaires consisted of 19 items which contained information on bio-demographic characteristics and hand hygiene practices. Data were analysed using SPSS-16 statistical software. Proportions were compared using Chi- square test and 'p' value less than 0.05 was considered statistically significant.

RESULTS

The response rate was 97.1%. There were 11 (16.7%) males and 55 (83.3%) females with a male to female ratio of 1: 5. The age of the participants ranged from 28-56 years with a mean age of 39.7±6.7. Washing of hands before and after contact with patient was 60.1% and 97% respectively. The difference was significant (p<0.01). Allergy to gloves was 15.2%. About three-quarter (77.3%) of the workers used soap and water to wash the hands when soiled or visibly contaminated. None of the workers used alcohol hand rub.

CONCLUSION

Though there was improved compliance to hand hygiene guidelines, this still fall short of acceptable standards. The provision and promotion of the proper use of alcohol-based hand rub may further improve compliance with hand hygiene by reducing the time required to perform it and the convenience of the method.

Practices of skin care among nurses in medical and surgical intensive care units: results of a self-administered questionnaire

Dermatitis of hands is a problem among nurses. The aim of this prospective questionnaire based survey was to analyze practice and knowledge of skin care of medical and surgical nurses. 250 questionnaires were distributed. 49% of respondent stated that they perform skin care at least 1-2 times/day. After hand-wash 15% of participants perform skin protection, after hand-disinfection only 2%. 40% give skin care products less than 3 minutes to be applied. It was shown that this knowledge is lacking in many individuals, leading to wrong behavior at work and insufficient use of skin protection and skin care products.

Hand eczema guidelines based on the Danish guidelines for the diagnosis and treatment of hand eczema

BACKGROUND

Classification of hand eczema has traditionally been based both on aetiology and clinical appearance. For 20% of cases, the aetiology is unknown.

OBJECTIVES

To suggest a classification based on well-defined aetiology as well as on predefined clinical patterns and on the dynamics of hand eczema.

METHODS

Literature studies and discussions among members of the Danish Contact Dermatitis Group.

RESULTS

Criteria are given for the aetiological diagnoses of allergic contact dermatitis of the hands, irritant contact dermatitis of the hands, protein contact dermatitis of the hands, atopic hand eczema and aetiologically unclassifiable hand eczema. Six different clinical patterns are described and illustrated. Suggestions for general treatment principles are given.

CONCLUSION

Operational guidelines for the diagnosis and treatment of hand eczema are described.

Infection in the critically ill--questions we should be asking

Best practice in infection control and management in the critically ill continues to generate considerable debate. The wide variation in current practice is witness to this continuing uncertainty. In large part this is due to the lack of a decent evidence base and to an over-reliance on deep-set dogma. Data that go against the grain are often conveniently overlooked and political imperatives frequently supervene. This article highlights some of these discrepancies and argues for a more balanced, scientific approach. In this time of financial restraint, we need to identify true priorities from both health and economic perspectives, and to see what practices can safely and effectively be modified or abandoned.

Innovative management of severe hand dermatitis

The successful treatment of hand dermatitis (HD) depends less on the selection of the proper topical steroid or a particular systemic agent than on addressing any underlying cause or perpetuating factor. Thus, innovative treatment is based on comprehensively addressing the patient's problem. Aggressive approaches may be required for the most severe forms of HD.

Trial of universal gloving with emollient-impregnated gloves to promote skin health and prevent the transmission of multidrug-resistant organisms in a surgical intensive care unit

OBJECTIVE

To compare the efficacy of universal gloving with emollient-impregnated gloves with standard contact precautions for the control of multidrug-resistant organisms (MDROs) and to measure the effect on healthcare workers' (HCWs') hand skin health.

DESIGN

Prospective before-after trial.

SETTING

An 18-bed surgical intensive care unit.

METHODS

During phase 1 (September 2007 through March 2008) standard contact precautions were used. During phase 2 (March 2008 through September 2008) universal gloving with emollient-impregnated gloves was used, and no contact precautions. Patients were screened for vancomycin-resistant Enterococcus (VRE) and methicillin-resistant Staphylococcus aureus (MRSA). HCW hand hygiene compliance and hand skin health and microbial contamination were assessed. The incidences of device-associated infection and Clostridium difficile infection (CDI) were determined.

RESULTS

The rate of compliance with contact precautions (phase 1) was 67%, and the rate of compliance with universal gloving (phase 2) was 78% (P = .01). Hand hygiene compliance was higher during phase 2 than during phase 1 (before patient care, 40% vs 35% of encounters; P = .001; after patient care, 63% vs 51% of encounters; P < .001). No difference was observed in MDRO acquisition. During phases 1 and 2, incidences of device-related infections, in number of infections per 1,000 device-days, were, respectively, 3.7 and 2.6 for bloodstream infection (P = .10), 8.9 and 7.8 for urinary tract infection (P = .10), and 1.0 and 1.1 for ventilator-associated pneumonia (P = .09). The CDI incidence in phase 1 and in phase 2 was, respectively, 2.0 and 1.4 cases per 1,000 patient-days (P = .53). During phase 1, 29% of HCW hand cultures were MRSA positive, compared with 13% during phase 2 (P = .17); during phase 1, 2% of hand cultures were VRE positive, compared with 0 during phase 2 (P = .16). Hand skin health improved during phase 2.

CONCLUSIONS

Compared with contact precautions, universal gloving with emollient-impregnated gloves was associated with improved hand hygiene compliance and skin health. No statistically significant change in the rates of device-associated infection, CDI, or patient MDRO acquisition was observed. Universal gloving may be an alternative to contact precautions.

Interventions for preventing occupational irritant hand dermatitis

BACKGROUND

Occupational irritant hand dermatitis (OIHD) is an important cause of discomfort in the working population. Different preventive measures are in place but it is not clear how effective these are.

OBJECTIVES

To assess the effect of interventions for preventing OIHD in healthy people who work in occupations where the skin is at risk of damage.

SEARCH STRATEGY

In May 2010, we searched the Cochrane Skin Group Specialised Register, the Cochrane Central Register of Controlled Trials in The Cochrane Library, MEDLlNE and EMBASE. Conference proceedings, and ongoing trials registers were also searched.

SELECTION CRITERIA

Randomised controlled trials (RCTs) studying the effectiveness of barrier creams, moisturisers, gloves, complex educational interventions, and other interventions for the prevention of OIHD.

DATA COLLECTION AND ANALYSIS

Two authors independently assessed the trials and extracted data.

MAIN RESULTS

Four RCTs involving 894 participants from different occupations were included. The primary outcome was numbers of new cases.One large RCT of 708 print and dye workers compared 2 barrier creams (containing silicone or hydrocarbon) versus no intervention. Fewer workers using barrier creams developed OIHD than those who did not (39.9% versus 45%, (OR 0.75, 95% CI 0.53 to 1.07. P = 0.11) but this was not statistically significant.In 1 RCT of 54 metal workers less developed OIHD when using an after work emollient or a barrier cream compared to no intervention. There was no statistical difference between the groups at different times of follow-up.One RCT of 111 cleaners and kitchen workers compared a moisturiser (Locobase) versus no intervention using a cross-over design. While using the moisturiser no participant developed OIHD. During the control period with no skin treatment, 19 (20.4%) out of 93 participants developed OIHD.One RCT of 21 hairdressers compared a barrier cream containing aluminium chlorohydrate (Excipial protect) versus its vehicle. No participant developed OIHD while the products were used.Only limited side-effects such as transient itching, stinging, and dryness were reported for the interventions.

AUTHORS' CONCLUSIONS

Although the findings of this review were generally positive, no statistical significance was reached. We conclude that at present there is insufficient evidence for the effectiveness of most of the interventions used in the primary prevention of OIHD. This does not mean that current measures are necessarily ineffective, as the limited studies to date have been rather small and of poor quality. Larger well designed RCTs are now needed in different workplaces to establish the effectiveness of various preventative strategies.

Effect of topical treatments on irritant hand dermatitis in health care workers

BACKGROUND

Irritant contact dermatitis (ICD) from repetitive hand hygiene is the primary reason for compliance failure among health care workers (HCWs). Chronic ICD has implications for infection control because higher bacterial counts are associated with increased skin compromise. Guidelines recommend lotions/creams to lessen irritation. We evaluated the effects of 5 to 10 daily applications of a test cream (A, glove and chlorhexidine gluconate compatible) and current lotions/creams (B) compared with a control of normal skin care.

METHODS

Outcomes were visual skin erythema and dryness, excess erythema (quantitative image analysis), and hydration among 80 HCWs in an intensive care unit.

RESULTS

Knuckle dryness was lower for both treatments than the no treatment control (P < .02) after 2 weeks. Skin treated with A had lower knuckle erythema (P=.03) than B and control. HCWs using A had lower excess erythema (right) than B and control (P < .04). Excess erythema was lower for A and B versus control (P=.003).

CONCLUSION

Reduction in erythema suggests that frequent use of cream A may mitigate the damaging effects of repetitive hand hygiene and allow the skin to recover. Intensive treatment of HCW ICD may be required to counteract the skin compromise and minimize the negative impact on infection control.

Effectiveness of skin protection measures in prevention of occupational hand eczema: results of a prospective randomized controlled trial over a follow-up period of 1 year

BACKGROUND

We recently found a very low adherence to a generally recommended skin protection regimen in a sample of 1355 metalworkers.

OBJECTIVES

The present study assessed the effectiveness of skin protection as presently recommended, especially the differential contribution of skin care and skin protection, to the prevention of occupational hand eczema. Methods Of 1355 metalworkers screened, 1020 male volunteers, all fit for work, were recruited for a prospective intervention study with four arms (skin care, skin protection, both combined, and control group, i.e. no recommendation). The study was performed from winter 2006/2007 to spring 2008, following each subject for up for 12 months. Both hands were examined using a quantitative skin score, and a standardized personal interview was performed three times. The change of the objective skin score from baseline to 12 months was used as primary outcome measure.

RESULTS

After 12 months 800 subjects were included (78.4% of those recruited). The compliance to follow the randomized measure depended on the recommended measure and ranged from 73.7% to 88.7%. While in the control group a significant deterioration was found, the largest and significant improvement was noted in the group following the generally recommended skin protection programme (skin care + skin protection) followed by skin protection alone as second best.

CONCLUSIONS

The generally recommended skin protection regimen seems to provide effective prevention of occupational skin disease. Therefore, the compliance to follow the skin protection regimen, especially the use of skin protection, should be enhanced.

The World Health Organization Guidelines on Hand Hygiene in Health Care and their consensus recommendations

The World Health Organization's Guidelines on Hand Hygiene in Health Care have been issued by WHO Patient Safety on 5 May 2009 on the occasion of the launch of the Save Lives: Clean Your Hands initiative. The Guidelines represent the contribution of more than 100 international experts and provide a comprehensive overview of essential aspects of hand hygiene in health care, evidence- and consensus-based recommendations, and lessons learned from testing their Advanced Draft and related implementation tools.

Use of digital photography and image analysis techniques to quantify erythema in health care workers

BACKGROUND/AIMS

Nosocomial infections affect up to 26% of ICU patients. Compliance with the required hand hygiene procedures remains low, rarely exceeding 50%, with skin irritation as one of the main reasons for lack of conformity. The aim was to quantify the epidermal barrier effects, particularly erythema, from repetitive exposure to hand hygiene procedures among health care workers (HCWs) using an objective, reliable clinical method that could evaluate the entire hand surface.

METHODS

The hand skin of HCWs was evaluated before the initial scrub and at the end of multiple 2-3 days work cycles during spring (n=54) and winter (n=60) trials. The skin condition was measured with live visual skin evaluation (LSG), digital image analysis (DIA) of high-resolution digital images, and visual perception evaluation (VPS) of image pairs.

RESULTS

The HCWs had significantly higher values of erythema than the non-HCW control group with all methods. Knuckle erythema increased over the cycle in both seasons. It decreased during recovery in spring and continued to increase during recovery in winter. For the DIA area of excess redness, the quantitative measure of erythema, the decrease over the cycle in spring was significantly different than the increase over the cycle in winter. Minimal changes in area of excess redness occurred during recovery in both seasons. With the VPS, both judges found a decrease in erythema during recovery in spring and an increase during recovery in winter, indicating significant differences for spring vs. winter (P<0.05). No differences in VPS erythema were seen for either product set over the work cycle during spring. Correlations were observed for (1) results for the VPS vs. the LSG method and (2) between excess erythema (mu+sigma) from DIA and the VPS erythema scores. Relatively low correlations were found between the DIA and VPS methods, i.e., knuckle mu+sigma and VPS erythema.

CONCLUSIONS

Significant work cycle effects for spring vs. winter were observed with DIA, while significant effects were found during the recovery period with VPS. DIA produced an objective quantitative measure of erythema that was not limited or influenced by other aspects of skin irritation (e.g., dryness, scaling) or texture encountered in the visual methods of LSG and VPS. The DIA method minimizes the difficulty in differentiating erythema severity. Standardization of image capture and processing allows assessment of skin condition across clinical locations. The VPS is a more reliable way to compare skin condition at different times, i.e. beginning vs. the end of a treatment cycle, because images are viewed simultaneously and can be carefully examined for differences.

Thiuram allergy--a potential dermal allergy among health care workers

Occupational health nurses should be cognizant of the myriad exposures that can result in dermal reactions among health care workers.

Nurses' perceptions of the benefits and adverse effects of hand disinfection: alcohol-based hand rubs vs. hygienic handwashing: a multicentre questionnaire study with additional patch testing by the German Contact Dermatitis Research Group

BACKGROUND

Nurses have a high risk of developing hand eczema due to hand disinfection procedures.

OBJECTIVES

To investigate the perception of nurses regarding the adverse effects of hand washing (HW) and alcoholic disinfection (ADI), and to obtain data on the prevalence of hand dermatitis and sensitization to alcohols and alcohol-based hand rubs (ABHRs).

METHODS

A self-administered questionnaire survey, carried out as a pilot study (PS), followed by a modified multicentre study (MC) in five hospitals. Patch tests to ethanol (80%), 1-propanol (60%), 2-propanol (70%) and ABHRs were performed in a subsample.

RESULTS

The majority (PS 60.1%; MC 69.5%) of nurses considered ADI to be more damaging than HW. Mostly, ADI and HW were suspected to have irritant effects (ADI 79.2%/52.1%; HW 65.5%/36.2%) compared with an allergenic potential (ADI 10.4%/5.8%; HW 7.8%/3.9%). The prevalence of hand dermatitis in the MC was 13.4% by self-diagnosis and 22.4% by symptom-based questions. In 50 tested individuals no sensitization and only two irritant reactions to alcohols and three single-positive reactions to ABHRs were observed, none of the latter related to alcohols.

CONCLUSIONS

Although ADI is known to cause less skin irritation than HW, nurses perceive ADI as more damaging, resulting in: (i) a low compliance with ADI and (ii) a higher prevalence of hand dermatitis because the more deleterious HW is preferred. This may result in an increase in occupational disease and nosocomial infections. Educational programmes should promote ADI as a procedure with good efficiency and skin tolerability to reduce the prevalence of hand eczema in nurses and to enhance compliance with hand hygiene standards.

Effectiveness of skin protection creams in the prevention of occupational dermatitis: results of a randomized, controlled trial

OBJECTIVES

The aim of the trial was to investigate whether the publicized effects of skin protection creams can be replicated in a real occupational setting during activities that expose the skin.

METHODS

A prospective, randomized, four-tailed controlled pilot trial was performed to compare the effect of skin protection and skin care alone or in combination with cleansing against a control group (only cleansing). Two branches were selected for the investigation: the building industry and the timber industry. A total of 1,006 workers from these two branches were recruited, and out of these 485 workers were examined longitudinally for at least three time points over 1 year (lost for follow-up: 430 workers, exclusion: 91 workers). At each time point, as a primary outcome measure, we assessed the condition of the skin at both hands in a blinded manner and the individual was assigned to one of the following categories: no eczema, mild, moderate and severe eczema. As a secondary outcome measure, the worker's transepidermal water loss (TEWL) was measured under standardized conditions at the back of both hands. In addition, the workers were asked to evaluate their skin condition during the study.

RESULTS

With regard to differences in the occurrence of eczemas, we found only in workers in building industry without application of skin protection or skin care creams a statistical significant increase in the incidence between the first and the second visit and a statistical significant decrease in the incidence between the second and third visit. When evaluating the secondary outcome-measurement changes in the TEWL values, an improvement was found for the group skin protection and skin care in combination and by skin care alone. Females in the timber industry started with better TEWL values than males, which may be due to better overall skin care. In this group we found an improvement for the group skin protection and skin care in combination and by skin protection alone. For skin protection alone, we noted a slight, but not significant improvement in all other groups. The subjective improvement of skin condition was reported from the participants who used skin protection and skin care in combination.

CONCLUSIONS

Taking all these secondary-outcome measurements together, the main result of this study was that skin protection creams alone have a small effect on the skin barrier in workers in the building and timber industries compared with skin care alone or in combination with skin protection.

Intervention implementation research: an exploratory study of reduction strategies for occupational contact dermatitis in the printing industry

BACKGROUND

Occupational dermatitis is a problem in the printing industry but can be avoided through adequate protective measures. Research into intervention implementation is fundamental to the success of a formal intervention effectiveness trial.

OBJECTIVES

The preliminary testing of four risk reduction strategies for occupationally caused dermatitis, which represent a range of approaches and cost implications.

PATIENTS/METHODS

The strategies, the provision of (i) skin checks plus treatment advice; provision of (ii) gloves of the correct type/size plus use of an after-work cream; provision of (iii) information highlighting the problem of occupational dermatitis and (iv) development of a best practice skin care policy, were evaluated over 3 months in two non-randomly selected companies. A post-intervention evaluation into the effectiveness and efficacy of the intervention was also carried out.

RESULTS AND CONCLUSIONS

All interventions were found to be acceptable to some extent. No single intervention appeared to be completely effective. The most practical intervention appeared to be the regular use of gloves of the correct type and size. This preliminary intervention study has demonstrated an improvement in the skin condition of workers examined and points towards the need for further testing of risk reduction strategies for the prevention of dermatitis in the printing industry on a much larger scale.

Skin reactions related to hand hygiene and selection of hand hygiene products

BACKGROUND

In October 2004, The World Health Organization (WHO) launched the World Alliance for Patient Safety. Within the alliance, the first priority of the Global Patient Safety Challenge is to reduce health care-associated infection. A key action within the challenge is to promote hand hygiene in health care globally as well as at the country level through the campaign "Clean Care is Safer Care." As a result, the WHO is developing Guidelines on Hand Hygiene in Health Care, designed to be applicable throughout the world.

METHODS

This paper summarizes one component of the global WHO guidelines related to the impact of hand hygiene on the skin of health care personnel, including a discussion of types of skin reactions associated with hand hygiene, methods to reduce adverse reactions, and factors to consider when selecting hand hygiene products.

RESULTS

Health care professionals have a higher prevalence of skin irritation than seen in the general population because of the necessity for frequent hand hygiene during patient care.

CONCLUSION

Ways to minimize adverse effects of hand hygiene include selecting less irritating products, using skin moisturizers, and modifying certain hand hygiene practices such as unnecessary washing. Institutions need to consider several factors when selecting hand hygiene products: dermal tolerance and aesthetic preferences of users as well as practical considerations such as convenience, storage, and costs.

Moisturizer effect on Irritant Dermatitis: an overview

Moisturizers are empirically used as prevention and treatment of surfactant and irritant dermatitis. Some products state they not only improve barrier function by providing moisturization but also create an environment optimal for healing. Yet, moisturizer clinical efficacy remains a topic of controversy. We reviewed publication from 1992 to 2006 that quantitatively examines moisturizer effectiveness, as an update of our prior overview, Zhai and Maibach in 1998 (2). We intuitively (in a testimonial sense) believe that moisturizers are sometimes effective for preventing and treating irritant dermatitis. However, moisturizer may not be broadly effective (8, 12) and may be relatively specific against certain acids, bases, hydrophilics, and lipophilics. We need to develop principles of what is formulated in moisturizers to improve efficacy; for this purpose, there is a need for experimental moisturizer models for comparative studies.

Dermatitis de manos

Hand dermatitis is a common skin disease that often has a chronic and relapsing course. Several subtypes of hand dermatitis have been described. In this review, we describe the clinical characteristics of each form of hand eczema, laboratory tests helpful in the diagnosis, and treatment options for this condition.

A systematic review of contact dermatitis treatment and prevention

BACKGROUND

Contact dermatitis (CD) is a common occupational disease. There have been no systematic reviews of CD treatment or prevention.

METHODS

Multiple databases were systematically searched. Using independent double review and published quality review criteria, articles were rated as good, fair, or poor. Treatment benefit data were tabulated and conclusions were based on the rated strength of published evidence.

RESULTS

In all, 49 studies met inclusion criteria. Barrier creams containing dimethicone or perfluoropolyethers, cotton liners, and softened fabrics prevent irritant CD. Lipid-rich moisturizers both prevent and treat irritant CD. Topical skin protectant and quaternium 18 bentonite (organoclay) prevent rhus dermatitis. Diethylenetriamine pentaacetic acid (chelator) cream prevents nickel, chrome, and copper dermatitis. Potent or moderately potent steroids effectively treat allergic CD. There were no macrolide immunomodulator trials that met inclusion criteria. This review did not include studies of children, animals, or non-English language publications.

CONCLUSIONS

A limited number of interventions effectively prevent or treat irritant and allergic CD, but well-controlled, outcome-blinded studies, particularly in the area of allergic CD prevention are needed.

Effect of camellia oil on the permeation of flurbiprofen and diclofenac sodium through rat and pig skin

The effect of camellia oil on the permeation of flurbiprofen (FP) and diclofenac sodium (DFS), used as model drugs, through rat and pig skin was examined. Two different types of camellia oil were used: one of them was purified by distillation and the other was purified by filtration without heating. The distilled camellia oil (DCO) and the filtered camellia oil (FCO) were applied to the skin as a pretreatment. Permeation of FP through the skins pretreated with FCO and DCO was enhanced, while that of DFS was suppressed. The effects of FCO were greater than those of DCO as far as enhancement and suppression were concerned. The effect of FCO on FP permeation could be due to oleic acid, one of the major components of FCO. On the other hand, FCO and oleic acid had opposite effects on the penetration of DFS. This result suggests that other active components which suppress the permeation of DFS may be present in FCO. Since the penetration-suppressing agents will be useful for skin care products, studies of such agents will be important in the future.

Hand hygiene: simple and complex

This review gives an overview of hand hygiene in healthcare and in the community, including some aspects which have attracted little attention, such as hand drying and cultural issues determining hand hygiene behaviour. Hand hygiene is the most effective measure for interrupting the transmission of microorganisms which cause infection both in the community and in the healthcare setting. Using hand hygiene as a sole measure to reduce infection is unlikely to be successful when other factors in infection control, such as environmental hygiene, crowding, staffing levels and education are inadequate. Hand hygiene must be part of an integrated approach to infection control. Compliance with hand hygiene recommendations is poor worldwide. While the techniques involved in hand hygiene are simple, the complex interdependence of factors which determine hand hygiene behaviour makes the study of hand hygiene complex. It is now recognised that improving compliance with hand hygiene recommendations depends on altering human behaviour. Input from behavioural and social sciences is essential when designing studies to investigate compliance. Interventions to increase compliance with hand hygiene practices must be appropriate for different cultural and social needs. New strategies to promote hand hygiene worldwide include the formation of public-private partnerships.

Allergic contact dermatitis: pathophysiology applied to future therapy

Contact dermatitis is a common reason for patient visits to primary-care clinics and represents up to 7% of all dermatologic consultations in the US. Substantial progress has been made in elucidating the pathophysiology of contact dermatitis, particularly the allergic form. A better understanding of pathologic mechanisms has led to improved management of cases and will continue to advance treatment modalities. The present paper reviews the pathogenesis and current treatment of allergic contact dermatitis and speculates on the prospects for improved future therapy.
