Editorial verdict
Methodologically cautious. The prevalence data is credible and the multiplicity correction is commendable, but a 35% duplicate-record problem, absent institution-level clustering, and very low model R-squared values (0.027–0.070) mean the subgroup and regression findings are exploratory at best — treat the descriptive burden figures as informative, the adjusted associations as hypothesis-generating only.
Executive summary
This cross-sectional study examines the mental health and occupational well-being of health-care workers across an integrated medical alliance in Shanghai, China, comprising one tertiary hospital, two secondary hospitals, and five community health-service centres. The authors argue that psychological symptom burden within such multi-institution networks remains understudied, and that describing its distribution across roles and settings has practical relevance for health-system management. A census-style electronic survey was administered to 825 eligible workers in 2024, yielding 669 administratively valid returns; a subsequent item-level audit identified 175 literal duplicate records, leaving 494 unique respondents. Using the DASS-21, ISI, and MBI-GS, the study found that 47.6% of respondents met or exceeded the mild depression threshold, 48.6% the mild anxiety threshold, 29.4% the mild stress threshold, and 51.4% scored above the no-clinically-significant-insomnia range. Mean MBI-GS scores were 2.58 for exhaustion and 2.26 for cynicism. After Holm correction across 70 omnibus tests, only ISI differences by years of work remained statistically significant. Exploratory adjusted models identified on-call shift pattern and older age as associated with higher insomnia scores. The authors explicitly characterise all associations as non-causal and note that institution-level clustering could not be modelled, limiting inferential precision.
Key insights
- 1After rigorous multiplicity correction across 70 omnibus subgroup tests, only insomnia severity differences by years of work experience survived as statistically significant, underscoring the hazard of interpreting raw subgroup p-values in occupational health surveys.
- 2A 35% duplicate-record rate in the exported dataset (175 of 669 rows) highlights a material data-integrity risk in platform-based survey research, requiring audit procedures that extend beyond administrative quality checks.
- 3On-call shift pattern was the most consistently associated occupational factor across exploratory adjusted models, appearing with higher depression, anxiety, stress, and insomnia scores, though institution-level clustering could not be accounted for and all estimates remain provisional.
Practical takeaways
- Organisations conducting electronic surveys in multi-institution settings may benefit from data-assembly audits that check for literal duplicate records before analysis, as export artifacts can substantially inflate apparent sample sizes.
- Descriptive prevalence data from this study — approximately half of respondents reporting clinically meaningful depression, anxiety, or insomnia symptom levels — can inform the scoping of workforce mental-health surveillance programmes within integrated medical alliances, provided local confirmation and institution-clustered analyses are conducted before targeting specific subgroups.
Frameworks mentioned
DASS-21
Depression Anxiety Stress Scales-21; a 21-item self-report instrument scoring depression, anxiety, and stress as separate subscales, each multiplied by two to yield conventional severity bands.
Insomnia Severity Index (ISI)
A seven-item self-report scale scoring sleep symptom severity from 0 to 28 across four bands: no clinically significant insomnia, subthreshold, moderate clinical, and severe clinical insomnia.
MBI-GS
Maslach Burnout Inventory-General Survey; a 16-item instrument measuring three burnout dimensions — exhaustion, cynicism, and professional efficacy — as continuous item-mean scores on a 0–6 scale.
