Abstract:
Occupational hygiene in healthcare settings addresses the identification, evaluation,
and control of risks that can cause occupational diseases among healthcare workers (HCWs).
This narrative review synthesizes prevalence data on injuries, infections, chemical exposures,
ergonomic hazards, and psychosocial stressors in HCWs worldwide. Data sources included
PubMed, WHO, OSHA, and NIOSH databases. Findings show that 39–60% of HCWs
experience occupational injuries annually or over their careers; bloodborne infections remain
a critical risk; chemical and ergonomic hazards contribute substantially to disease burden;
and psychosocial risks are rising. Effective control measures—engineering controls,
administrative policies, personal protective equipment (PPE), and training—are discussed.
Two tables summarize prevalence rates and control strategies. Recommendations call for
strengthening occupational hygiene programs through risk assessments, surveillance, and
policy enforcement.
Keywords:

pathogens, musculoskeletal disorders, chemical exposures, ergonomic hazards, psychosocial
risks
INTRODUCTION
Healthcare workers (HCWs) are essential to patient care but face diverse occupational
hazards that can lead to professional diseases and injuries. WHO estimates that HCWs are
exposed to infections, unsafe patient handling, hazardous chemicals, radiation, heat, noise,
psychosocial hazards, and workplace violence, all of which pose risks to their health and
safety.
Bloodborne pathogens (e.g., hepatitis B, hepatitis C, HIV) are among the most significant
infectious hazards, with sharps injuries and mucocutaneous exposures leading to transmission
events in up to 3.5 per 100 sharps injuries per year in some settings. Ergonomic hazards—
including patient lifting and repetitive tasks—are linked to musculoskeletal disorders in 39–
60% of HCWs over their careers. Chemical exposures (e.g., disinfectants, latex) contribute to
occupational asthma and dermatitis, affecting 10–30% of exposed workers. Psychosocial
stressors, including burnout and workplace violence, additionally compromise worker well-
being and performance.
Recognizing these risks, occupational hygiene employs systematic approaches—anticipation,
recognition, evaluation, and control—to protect HCWs. This review aims to (1) quantify the
prevalence of occupational diseases among HCWs, (2) characterize major hazard categories,
and (3) describe control measures and policy frameworks.

METHODS
Search Strategy - A narrative review was conducted using searches on PubMed, WHO,
OSHA, and NIOSH websites for publications from January 2019 to April 2025. Search terms
included “occupational hygiene healthcare workers,” “occupational diseases,” “healthcare
occupational risk,” and “HCW injuries prevalence.” Key databases searched:
PubMed/MEDLINE, WHO Fact Sheets, OSHA healthcare pages, and NIOSH topic pages.
Inclusion and Exclusion Criteria - Studies were included if they reported quantitative data on
occupational injuries, infections, chemical exposures, ergonomic hazards, or psychosocial
risks among HCWs. Reviews, original research articles, and organizational fact sheets in
English were eligible. Studies focusing solely on non-healthcare sectors or lacking
quantifiable outcomes were excluded.
Data Extraction and Synthesis - From each source, data on prevalence, hazard types, and
control measures were extracted. Two summary tables were created: Table 1 on prevalence
rates and Table 2 on control strategies. A qualitative synthesis discusses major findings.

RESULTS
Prevalence of Occupational Injuries and Diseases - A cross-sectional study in a developing-
country hospital reported that 39% of HCWs experienced an occupational injury in the past
year and 60% over their careers, with sharps injuries (25%), needlesticks (18%), and
slips/trips (12%) most common. In Turkey, nationwide data indicate that sharps injuries
account for 48% of reported incidents and falls for 22% over five years.
Infectious Hazards - HCWs face substantial risk from bloodborne pathogens. WHO notes that
before widespread hepatitis B vaccination, transmission risk per needlestick was as high as

30% for HBV; current global seroconversion rates after exposure are 0.3% for HCV and
0.3% for HIV per incident without prophylaxis. OSHA highlights tuberculosis, influenza, and
emerging coronaviruses as persistent airborne threats, with annual incidence rates among
HCWs up to 5 times those of the general population in high-burden regions.
Chemical and Physical Hazards - Exposure to latex and disinfectants is linked to occupational
asthma, dermatitis, and sensitization in 10–20% of exposed HCWs. Waste anesthetic gases,
formaldehyde, and antineoplastic drugs pose additional toxicological risks, with evidence of
reproductive effects and carcinogenicity in uncontrolled settings. Radiation workers (e.g.,
radiology technologists) show cumulative dose-related cataracts and potential long-term
cancer risks
Ergonomic Hazards - Musculoskeletal disorders (MSDs) affect over 50% of nurses, primarily
involving the lower back (35%) and shoulders (28%) due to patient handling. Engineering
controls (e.g., mechanical lifts), administrative policies (e.g., safe patient handling programs),
and training reduce injury rates by up to 60% when properly implemented.
Psychosocial Risks and Violence - Recent data indicate that 50–75% of hospital staff
experience workplace violence annually, including verbal abuse and physical assaults, with
higher rates in emergency and psychiatric units. Burnout prevalence reaches 55% among
physicians and 40% among nurses, driven by workload, staffing shortages, and emotional
stressors.
DISCUSSION
This review confirms that HCWs worldwide are at high risk for a spectrum of occupational
diseases and injuries. The high prevalence of sharps injuries and MSDs underscores the need
for sustained investments in engineering controls and training programs. Bloodborne
infections remain a critical concern despite vaccination and prophylaxis; comprehensive
infection control must be prioritized. Chemical and radiation hazards require robust
monitoring and PPE adherence. Rising psychosocial risks suggest that occupational hygiene
programs must broaden to encompass mental‐health interventions and violence prevention
policies.
Policy implications include:
Strengthening Surveillance: Mandatory reporting of occupational injuries and exposures to
inform prevention strategies.
Enhancing Engineering Controls: Wider adoption of no-needle IV systems and patient lifts.
Improving Administrative Measures: Implementing safer staffing models and shift rotations
to reduce fatigue.
Expanding Training: Regular, competency-based training in infection control, chemical
safety, and ergonomic techniques.
Integrating Mental Health: Providing counseling services and zero-tolerance policies for
workplace violence.
Limitations of this review include heterogeneity in study designs and regional focus, which
may limit generalizability. Future research should examine long-term outcomes of emerging
hazards (e.g., nanomaterials) and evaluate cost-effectiveness of control interventions.

CONCLUSION
Occupational hygiene in healthcare is vital to safeguarding HCWs from diverse hazards.
High rates of injuries, infections, chemical exposures, ergonomic disorders, and psychosocial
stressors demand comprehensive risk management. By integrating engineering controls,
administrative policies, PPE, training, and mental health support, healthcare organizations
can substantially reduce occupational disease burdens and improve worker well-being.
