Key Highlights

• Clinical-year medical students in the UAE report significantly increased handwashing and hand sanitiser use, paralleled by a marked worsening in hand skin health—especially among female students—and higher symptom rates such as dryness, itching and fissuring.
• Poor hand skin health affected hygiene behavior for a minority of students and influenced specialty choice for nearly 10%; pragmatic, evidence-based interventions (emollient access, product selection, education, occupational pathways) reduce dermatitis and support sustained infection control.

Introduction

Medical students crossing the threshold from classroom to bedside encounter more than unfamiliar routines and new responsibilities. They enter an environment that demands frequent hand hygiene, prolonged glove use and direct patient contact—conditions that routinely strain skin integrity. A recent cross-sectional study of medical students at Mohammed Bin Rashid University of Medicine and Health Sciences (MBRU) in Dubai documents how that occupational exposure translates into measurable changes in hand skin health, hygiene habits and even career thinking. The findings expose a preventable occupational hazard that merits institutional action: straightforward changes in products, policy and clinical education can preserve skin health without undermining infection control.

The dataset captures a transition many institutions worldwide have observed since intensified hygiene measures during the COVID-19 era: increased infection-control activity is correlated with rising rates of irritant and allergic hand dermatitis. The UAE study quantifies those changes among clinical trainees and highlights gendered differences, placement-specific risks and gaps between perception and evidence about hand hygiene products. The consequences extend beyond discomfort—affecting performance, psychosocial wellbeing and specialty preferences—so targeted mitigation is both humane and practical.

The following sections synthesize the study’s results, contextualize them with international evidence and translate them into actionable recommendations for students, educators and healthcare administrators.

Clinical training increases exposure — and skin injury

The survey recruited 81 medical students (response rate 54.4%) from MBRU across cohorts graduating 2024–2026, average age 23.1 years; 77.8% were female. Responses compared pre-clinical (years 1–3) and clinical (years 4–6) experiences, focusing on hand hygiene frequency, skincare practices and perceived changes in hand skin health.

Key quantitative shifts between pre-clinical and clinical years:

• Mean daily handwashes rose from 6.1 to 9.4 (p = 0.0002).
• Mean daily hand sanitiser uses rose from 4.6 to 10.1 (p = 0.0001).
• Overall adherence to hand hygiene protocols increased (22.2% → 51.9%; p = 0.0001).
• Presence of symptoms attributed to poor hand skin health increased (17.3% pre-clinical → 25% clinical).

Those numbers show two predictable but important dynamics. First, clinical exposure generates additional, legitimately required hand hygiene events—during ward rounds, procedures and close patient care. Second, higher frequency of washing and antiseptic use correlates with greater reports of dryness, itching, burning and fissuring. The trend mirrors data reported from Europe and Asia after intensified hygiene practices during the SARS-CoV-2 pandemic, where healthcare workers experienced increased irritant contact dermatitis.

The practical implication is straightforward: the clinical setting imposes a sustained, repeated irritant load on the skin. Each handwash or antiseptic application, particularly when combined with gloves, chips away at the skin’s hydrolipid barrier. Repeated disruption prevents recovery and predisposes to chronic dermatitis.

Clinical placements with the greatest self-reported impact included surgery, medicine, emergency medicine and critical care (ICU/NICU). Those rotations typically involve frequent procedures, glove changes and patient contact—conditions that amplify exposure.

This pattern places clinical students in the same occupational risk category as junior nurses and allied health staff, and not merely as learners performing theory. Their hand hygiene frequency and exposure profiles approximate those of early-career clinicians, which makes early preventive interventions especially valuable.

Gender patterns, family history and skincare behavior

The MBRU sample revealed gendered differences in family history and responses to skin symptoms. Female students reported a substantially higher family history of chronic skin disease—predominantly atopic eczema—and were more likely to adopt skincare routines and use topical products, both prescription and non-prescription.

Women in the survey were more likely to report worsening hand skin health after entering clinical years: 60.3% of female respondents noted deterioration compared with a majority of male students reporting no change. Female students also reported larger increases in handwashing duration and adherence, suggesting a dual pressure: greater exposure and a higher personal emphasis on protocol compliance.

Atopic heredity matters because it lowers the threshold for irritant dermatitis. Individuals with a background of atopic dermatitis possess a persistently altered skin barrier and more reactive skin; frequent washing and solvent exposure accelerate symptom emergence. The higher prevalence of reported family history among female students helps explain, in part, the gender differences in symptom burden.

The behavioral response to symptoms also diverged. Female students were more likely to alter skincare routines and to seek topical treatments. Yet despite higher symptom awareness and product use, dermatology consultations remained low across the cohort, pointing to barriers in access, awareness or perception of severity.

This pattern implies two targets for intervention:

• Tailored education addressing students with pre-existing skin sensitivity, including early counseling and access to dermatology.
• Universal availability of preventive options so that all students—not only those who adjust their routines—receive protective resources.

Placement-specific risks: where and why symptoms spike

Students singled out several specialties where hand skin health worsened most: surgery, medicine, emergency medicine, ICU/NICU. These environments share elements that increase risk.

High-contact settings

• Increased frequency of patient contact and procedural tasks.
• More opportunities for contamination and thus higher frequency of hand hygiene before and after contact.

Procedure-heavy rotations

• Repeated donning and doffing of gloves.
• Exposure to antiseptics, disinfectants and cleaning agents used around procedures.

Time pressure and stress

• Rushed hygiene that may involve aggressive washing or incomplete drying.
• Reliance on gloves as perceived substitutes for hygiene.

Example: surgical rotations often require pre-op scrubbing, sterile gloving, instrument handling and frequent glove changes. Several students reported deterioration during surgical placements—likely reflecting the cumulative insult from scrubbing protocols, antiseptic agents and glove occlusion.

Critical care areas amplify exposure. ICU and NICU staff perform frequent bedside interventions, with multiple rapid hygiene events and extended periods wearing gloves and protective equipment. The combination of repeated cleansing and prolonged occlusion predisposes to maceration and irritant dermatitis.

Emergency departments operate under high throughput and unpredictable workflows. Rapid transitions between patients, urgent hygiene needs and intermittent access to emollients create a setting where protection is difficult and dermatitis risk is elevated.

Understanding placement-specific risks allows targeted solutions: ensuring emollient stations in high-risk wards, scheduling brief rotations that allow recovery where possible, and guaranteeing occupational support in procedure-heavy units.

Perceptions versus evidence: soap, sanitiser and gloves

The study captured several common beliefs about hand hygiene products that diverge from evidence.

Soap versus hand sanitiser A majority of students (71.6%) believed soap to be both more effective and gentler than alcohol-based hand sanitisers. Clinical evidence shows a more nuanced picture:

• Soap and water effectively remove organic soiling and a broad range of pathogens mechanically.
• Alcohol-based hand rubs (ABHRs) provide rapid antiseptic action against many pathogens and are the preferred method in most clinical situations when hands are not visibly soiled.
• Modern ABHRs often include emollients that reduce evaporative skin damage; studies have found alcohol-based gels can be less irritating than frequent soap-and-water washing if emollients are present.

The practical takeaway: use soap and water when hands are visibly soiled or after handling bodily fluids; use ABHR for routine decontamination between clean contacts. ABHRs formulated with moisturisers reduce skin injury risk and should be available across point-of-care locations.

Glove use misconceptions Some students perceived gloves as an alternative to hand hygiene. Gloves prevent cross-contamination only when used appropriately and combined with hand hygiene. Wearing gloves without performing hand hygiene before and after glove use risks contamination of the glove exterior during donning and of hands during removal. Studies have documented hand contamination even when gloves are used, emphasizing that gloves are protective tools—not substitutes.

Product selection matters Not all soaps and sanitisers are equal. The irritant potential depends on:

• pH and surfactant composition of soaps.
• Alcohol concentration and the presence of emollients in ABHRs.
• Fragrances, preservatives and antiseptic additives that can trigger allergic contact dermatitis.

Institutions that standardize procurement toward pH-balanced, fragrance-free soaps and ABHRs with added emollients reduce adverse skin events. The WHO hand hygiene guidelines underscore that product choice influences both effectiveness and tolerability.

Impact on behaviour, wellbeing and career choices

The physical symptoms from hand skin damage translated into behavioral and psychosocial effects in the MBRU cohort.

Hygiene adherence A minority (17.3%) acknowledged that poor skin health negatively influenced adherence—rushing handwashing, avoiding soap or sanitiser, or relying on gloves to bypass uncomfortable cleansing. Even if this is a small proportion, its significance is disproportionate: lapses in hand hygiene create infection risks for patients and staff.

Clinical confidence and training Persistent hand pain, fissuring or burning discourages repetitive tactile examination. Eight students (9.9%) stated that hand skin health influenced their career preferences, steering them away from high-contact specialties. If replicated at scale, this occupational factor could skew specialty distribution and diminish the pool of clinicians willing to pursue procedure-heavy roles.

Social and emotional burdens Students reported embarrassment (e.g., when shaking hands), discomfort in daily tasks such as washing dishes or handling objects, and a heightened self-consciousness. These are real impediments to quality of life and professional interactions; they compound the physical toll and justify preventive action.

Workplace consequences Beyond individual consequences, occupational hand dermatitis imposes economic and staffing costs. In the broader literature, severe hand dermatitis correlates with sick leave, reduced productivity and, in extreme cases, changes in vocation. Among trainees, early onset of occupational dermatitis could lead to absenteeism during critical training periods and strain on clinical supervision.

Preventive strategies that work — institutional and individual

The MBRU study reinforces the effectiveness of known, low-cost interventions for preventing and managing occupational hand dermatitis. Evidence from randomized trials and occupational programs supports these approaches.

Institutional measures

1. Provide accessible emollients at point of care
   • Place lotion/cream dispensers beside sinks and ABHR dispensers.
   • Ensure dispensers supply fragrance-free, ceramide-containing or urea-based emollients where appropriate.
   • Evidence: randomized and controlled interventions show that cream stations increase emollient use and reduce dermatitis incidence.
2. Standardize procurement toward skin-friendly products
   • Adopt pH-balanced, non-antimicrobial cleansers for routine use and ABHRs with emollients.
   • Avoid products with known sensitizers (e.g., fragrances, certain preservatives) in clinical areas.
3. Integrate skin protection education into clinical training
   • Teach appropriate moments and methods for hand hygiene (WHO protocol), plus advice on emollient timing (immediately after handwashing, at shift end, before sleep).
   • Address misconceptions: explain efficacy contexts of ABHR versus soap and the correct role of gloves.
4. Create dermatology referral pathways
   • Offer rapid-access occupational dermatology for students and staff.
   • Facilitate early treatment (topical steroids or other prescribed measures) to prevent chronicity.
5. Monitor and audit
   • Include skin health metrics in occupational health surveillance.
   • Use anonymous surveys to track incidence and severity among staff and trainees.
6. Adjust workflow and duty rotation when necessary
   • For trainees with established dermatitis, limit time in high-exposure placements when possible and provide alternative assignments until recovery.

Individual-level strategies

1. Choose appropriate emollients
   • Use fragrance-free, preservative-minimized creams or ointments.
   • Ceramide-containing formulations restore barrier lipids and have been effective in secondary prevention trials.
   • Apply emollients liberally after washing, between breaks, and at bedtime.
2. Optimize hand hygiene technique
   • Use ABHR for routine decontamination when hands are not visibly soiled.
   • When soap-and-water is required, use lukewarm water and gentle washing techniques; pat hands dry rather than vigorous rubbing.
3. Protect during high-risk tasks
   • Wear gloves when indicated, but perform hand hygiene before donning and after removal.
   • Minimize prolonged glove occlusion when not clinically necessary.
4. Seek early assessment
   • Consult occupational health or dermatology at first signs of persistent erythema, fissuring, or pain.
   • Early topical therapy can abort progression to chronic eczema.
5. Avoid self-treatment with potentially sensitizing over-the-counter products
   • Some "antibacterial" soaps and cosmetic creams contain allergens. Prefer clinician-recommended products if symptoms begin.

Implementation example: a ward-level pilot A practical approach is a pilot that pairs product change with education. In one documented study, providing ceramide-containing creams and brief training reduced dermatitis recurrence among affected workers. A pilot at the ward level might include:

• Installing emollient dispensers by sinks and charting their usage.
• Running a 30-minute session for trainees on product selection, timing and glove management.
• Collecting pre- and post-intervention self-reported skin health and hand hygiene adherence over three months.

The anticipated outcome: improved skin scores, increased emollient uptake and no deterioration in infection control metrics.

Evidence from trials and occupational programs

The MBRU study aligns with international evidence that multifaceted programs reduce occupational hand dermatitis.

Randomized and controlled data

• A trial evaluating a skin-care program that combined a ceramide-containing cream with personalized training demonstrated secondary prevention of hand dermatitis in healthcare workers.
• Cluster randomized behavior-change packages in nursing populations reduced hand dermatitis incidence and improved protective behaviors.

Observational findings

• Studies from the COVID-19 era reported increased skin damage among frontline staff, particularly with prolonged glove use and frequent washing.
• Surveys have documented misconceptions about gloves and ABHRs, leading to misuse and increased dermatitis risk.

Economic analyses

• Interventions that reduce dermatitis incidence decrease sick leave and treatment costs, producing favorable cost-benefit profiles for institutions.

Taken together, this body of work supports systemic, evidence-based interventions that combine product provision, education and occupational follow-up.

Designing a practical skin protection policy for teaching hospitals

A skin protection policy should be concrete, measurable and integrated into existing infection control frameworks.

Core elements

• Product formulary: select ABHRs with emollients, pH-balanced soaps, and at least one ceramide-based emollient for institutional supply.
• Distribution plan: ensure one emollient dispenser per clinical bay and ABHR at point of care.
• Education: hand hygiene curricula should include skin health, product selection and proper glove practice during orientation and periodic refreshers.
• Occupational access: designate an occupational health or dermatology contact and define a fast-track referral mechanism.
• Monitoring: collect data on emollient usage, dermatitis cases, absenteeism and self-reported adherence quarterly.

Operational considerations

• Procurement: contract with vendors to supply refillable, tamper-proof dispensers that dispense appropriate cream formulations.
• Budgeting: model savings from reduced sick leave and lower treatment costs against upfront procurement. Trials show downstream savings when dermatitis incidence falls.
• Stakeholder engagement: involve infection control, occupational health, pharmacy, nursing leadership and student representatives to design and evaluate the program.

Measurement of success

• Pre- and post-implementation surveys of hand skin symptoms and product uptake.
• Tracking dermatology clinic referrals for hand dermatitis.
• Monitoring hand hygiene compliance to ensure infection control standards are maintained or improved.

Barriers and how to overcome them

Common obstacles impede implementation: budget constraints, supply chain inertia, skepticism about benefits and competing priorities. Address these with targeted strategies.

1. Budget constraints
   • Start with a pilot in high-risk wards to demonstrate impact before scaling.
   • Use cost-offset analysis to show reduced absenteeism and treatment costs.
2. Supply chain and procurement policies
   • Engage pharmacy procurement teams with evidence summaries and clinical endorsements.
   • Present product samples and endorseable safety data sheets to purchasing committees.
3. Cultural inertia and misconceptions
   • Use brief, data-driven educational sessions that clarify ABHR vs soap use and glove practice.
   • Share trainee testimonials and peer-led demonstrations to increase buy-in.
4. Accessibility and convenience
   • Emollients must be as easy to use as ABHRs; place dispensers at point-of-care and ensure refills.
   • Use pump or wall-mounted dispensers to minimize disruption.
5. Monitoring fatigue
   • Integrate skin-health questions into routine occupational health check-ins or existing compliance audits to reduce additional reporting burden.

Future research directions

The MBRU study raises questions that warrant larger, multi-center research:

• Longitudinal studies that track incident dermatitis as students progress into residency, linking early exposure to long-term outcomes.
• Randomized ward-level trials comparing different ABHR formulations and emollient strategies.
• Cost-effectiveness analyses specific to low- and middle-income healthcare settings.
• Objective measures of skin barrier function (e.g., transepidermal water loss) before and after interventions to supplement self-reported outcomes.
• Qualitative work exploring barriers to dermatology care among trainees.

Such studies would refine prevention strategies, quantify institutional return on investment and guide procurement choices.

Practical guidance for students and supervisors

For students

• Use ABHR with emollients for routine hand decontamination; wash with soap and water when hands are visibly soiled.
• Apply an emollient after every wash and at the end of shifts. Keep a small, approved cream in your bag for pickups between tasks if institutional dispensers are unavailable.
• If you have atopic dermatitis or recurrent hand problems, notify occupational health early and request a dermatology referral.
• Do not use gloves as a substitute for hand hygiene; clean hands before donning and after removing gloves.

For supervisors and educators

• Model proper hand hygiene behavior, including visible use of emollients when appropriate.
• Integrate skin health counseling into clinical skills teaching—explain practical management during rotations that involve frequent handwashing or glove wear.
• Ensure students know where to access occupational health and institutional creams.

A brief checklist for clinical units

• ABHR at every point of care and sinks stocked with pH-balanced soap.
• Emollient dispensers adjacent to sinks and ABHR stations.
• Training sessions at student orientation and at each rotation start.
• Easy referral process to occupational dermatology.

Limitations and interpretative caution

The source study used self-reported survey data from a single medical school with a modest sample size (81/149). Self-reporting introduces recall and reporting biases. The cross-sectional design cannot prove causation, only associations between increased hygiene and worsened skin health. The study did not use objective dermatologic assessment or validated questionnaires for diagnosis; instead it captured perceptions and symptoms. These limitations do not invalidate the findings but they constrain generalizability. The trends align with broader international observations, which strengthens the inference that increased clinical exposure raises dermatitis risk.

Despite these limitations, the study provides actionable insights for prevention during a critical stage of professional development. Because clinical students already perform hygiene tasks similar to healthcare workers, pragmatic workplace changes are justified even while more robust surveillance is established.

Closing perspective

Hand dermatitis among medical trainees is an occupational issue with clinical, educational and psychosocial dimensions. Its prevention requires neither extravagant resources nor complex policy shifts. Practical measures—skin-friendly product selection, emollient availability at point of care, education integrated into clinical curricula and accessible dermatology support—reduce symptoms and enable safe patient care.

Addressing skin health preserves students’ ability to conduct physical examinations, sustains adherence to infection control and removes a modifiable barrier to specialty choice. For teaching hospitals and clinical departments, protecting trainee skin health is a low-barrier intervention with tangible returns: healthier trainees, improved morale and sustained standards of care.

FAQ

Q: What is occupational hand dermatitis and how does it differ from regular dry skin? A: Occupational hand dermatitis encompasses inflammatory conditions—irritant or allergic contact dermatitis—triggered or worsened by workplace exposures. Regular dry skin lacks the characteristic inflammation, fissuring, or recurrent flares tied to specific irritants or allergens. Occupational cases are typically related to repeated exposure to soaps, antiseptics, detergents and occlusion from gloves.

Q: My hands feel dry and crack after long shifts. When should I seek dermatology care? A: See occupational health or a dermatologist if symptoms persist beyond a week of conservative care, if you develop fissures, bleeding, intense pain, or recurrent infections, or if symptoms impact your work or daily activities. Early assessment permits topical treatment and advice to prevent chronicity.

Q: Which is gentler on my hands: alcohol-based hand rubs or washing with soap and water? A: Both methods are effective when used in their appropriate contexts. Alcohol-based hand rubs formulated with emollients tend to be less drying than frequent soap-and-water washes, especially when hands are not visibly soiled. Use soap and water when hands are visibly dirty or contaminated with bodily fluids. Choose ABHRs and soaps with skin-friendly formulations.

Q: Do gloves protect my hands from dermatitis? A: Gloves prevent cross-contamination but do not prevent dermatitis caused by frequent washing and antiseptic use. Prolonged occlusion inside gloves can aggravate skin irritation by trapping sweat and macerating the skin. Use gloves when clinically indicated and perform hand hygiene before donning and after removing them.

Q: What products should institutions provide to reduce dermatitis risk? A: Provide ABHRs with emollients, pH-balanced mild soaps, and fragrance-free emollient creams or ointments (ceramide-containing formulations are advantageous). Place emollient dispensers beside sinks and ABHR stations to maximize use.

Q: How often should I apply emollient during a shift? A: Apply an emollient after every handwash and as needed between tasks, particularly during breaks. A generous application at the end of each shift and a thicker ointment at bedtime help restore the skin barrier.

Q: Can hand dermatitis influence my career choices as a clinician? A: For some trainees, persistent hand symptoms reduce comfort with repeated tactile patient contact and may discourage pursuit of high-contact specialties. Institutional prevention and early treatment reduce that risk.

Q: Are there any simple, low-cost pilots departments can run to address this? A: Yes. A ward-level pilot that installs emollient dispensers, supplies ABHRs with emollients, runs brief skin-health education for staff and trainees, and measures self-reported symptom rates and emollient usage over three months can demonstrate benefit and inform broader rollout.

Q: Will instituting emollient stations undermine infection control? A: No. When placed and maintained properly, emollient dispensers support infection control by facilitating hand skin recovery without compromising hand hygiene. Ensure dispensers are designed for clinical use and refilled through central supply to avoid contamination risks.

Q: What are the research gaps and next steps? A: Larger, multicenter longitudinal studies and randomized ward-level trials comparing product strategies would refine recommendations. Objective skin measurements and cost-effectiveness analyses would strengthen the business case for institutional investment.

If you are a student, educator or clinical leader: begin with a small, measurable change—add an emollient dispenser to a high-contact ward and run a short, evidence-based session on product use. The resulting improvements in skin health and comfort will be immediate and measurable, supporting both trainee wellbeing and high-quality patient care.
