An insourced, multidisciplinary Employee Assistance Program at a Singapore tertiary hospital demonstrated a statistically significant decrease in median PHQ-4 scores from 7 pre-EAP to 2 post-EAP, with 59% of participants able to return to work at an estimated average running cost of $648.48 per participating staff.
Key Findings
Results
Nursing staff formed the largest proportion of EAP participants.
Data from a total of 39 EAP participants were analyzed.
Nursing staff comprised 51.3% of staff who utilized the EAP.
The study period ran from 01 January 2024 to 30 April 2025.
The EAP was implemented at a tertiary hospital in Singapore.
Results
Departmental referral was the most common route of access to the EAP, followed equally by self-referral and peer-supporter referral.
Referral by the staff's department accounted for 43.6% of EAP access.
Self-referral accounted for 23.1% of access.
Referral by a peer-supporter also accounted for 23.1% of access.
Multiple referral pathways were available within the multidisciplinary program structure.
Results
Work-related stressors were the most common reason for EAP attendance.
Work-related stressors accounted for 48.7% of reasons for EAP attendance.
The finding was based on 39 EAP participants analyzed over the study period.
The EAP included Occupational Medicine Physicians, Psychiatrists, Psychologists, and Human Resource Professionals.
Results
EAP participation was associated with a statistically significant improvement in psychosocial wellbeing as measured by the PHQ-4.
A statistically significant decrease between the median pre-EAP PHQ-4 score (7) and median post-EAP PHQ-4 score (2) was noted.
The Patient Health Questionnaire-4 (PHQ-4) was used as an objective clinical questionnaire to measure psychosocial wellbeing.
The study used anonymous longitudinal data collected from all participants enrolled in the EAP.
The median PHQ-4 score decreased by 5 points from pre- to post-EAP assessment.
Results
The majority of EAP participants were able to return to work following program participation.
59% of EAP participants were able to return to work.
This outcome was measured across 39 participants enrolled between 01 January 2024 and 30 April 2025.
Return to work was reported as one of the key effectiveness outcomes of the EAP evaluation.
Results
The estimated average running cost to sustain the EAP was $648.48 per participating staff.
An estimated average running cost of $648.48 per participating staff was required to sustain the program.
The EAP was described as insourced and multidisciplinary.
Cost was reported as one dimension within the health service evaluation framework used.
The evaluation analyzed the EAP across five dimensions: Reach and Adoption, Effectiveness, Implementation, and Maintenance.
Conclusions
This study represents the first longitudinal evaluation of an EAP described in Southeast Asia.
The authors state this is 'the first longitudinal study in Southeast Asia describing the evaluation of an EAP.'
The study utilized a health service evaluation framework.
The authors propose that the evaluation methods and outcomes described 'provide a framework for companies and human resources departments to review ongoing EAPs.'
The study analyzed anonymous longitudinal data of all participants enrolled over a 16-month period.
