Study Type: Cross-sectional survey analysis (survey-weighted descriptive analysis of US PH WINS national workforce data).

Key Question: How do local health department supervisors and their staff perceive workload, resources, burnout, and retention, and does this differ by rurality?

Key Findings:

• Nearly half of supervisors in both rural and urban settings reported insufficient staffing and funding.
• Nonsupervisors' satisfaction with their supervisors was significantly higher in rural than urban settings, though high in both, and was commonly cited as a reason for staying.
• Authors report substantial burnout and intention to leave among supervisors in both settings; abstract provides no effect sizes, confidence intervals or exact proportions.

Clinical Relevance: Supervisor burnout and resource constraints may parallel pressures in UK local authority public health teams and NHS management, informing workforce retention and leadership support strategies, though US findings may not transfer directly.

Limitations: Descriptive, cross-sectional design precludes causal inference, and US local health department structures differ substantially from the UK system.

Study Type: Cross-sectional survey analysis (secondary analysis of the 2024 US Public Health Workforce Interests and Needs Survey; self-reported data).

Key Question: What is the self-reported competency profile of the US state and local governmental epidemiology workforce, and which factors are associated with proficiency?

Key Findings:

• Proficiency was lowest in data modernisation (42.3%) and information systems (36.8%); mean composite competency score was 3.28/5 (SE 0.04).
• Higher proficiency was associated with a master's degree (AOR 1.80), doctorate (AOR 2.96), and epidemiology specialisation (AOR 1.63), all P < .01.
• Proficiency rose across epidemiology tiers, with larger gaps in early-career staff and those without relevant education or training.

Clinical Relevance: The informatics and data modernisation gaps are likely transferable to UK health protection and intelligence teams, supporting workforce development priorities around digital and data skills.

Limitations: Competency was self-rated and dichotomised, which risks over- or under-estimation and loses granularity, and findings reflect the US system, limiting direct UK generalisability.

Study Type: Cross-sectional survey analysis (2024 Public Health Workforce Interests and Needs Survey), with weighted estimates and multivariable logistic regression.

Key Question: How do turnover intentions, reasons for leaving, and desired benefits differ between public health workers aged ≤35 in the US-Affiliated Pacific Islands (USAPIs) and the mainland US?

Key Findings:

• Intent to leave within one year was similar: 25.6% (USAPI) vs 28.6% (US); P = .15. Pay was the leading reason in both groups (58.8% vs 66.5%; P = .08).
• USAPI staff were far more likely to cite non-job-related reasons for leaving (41.6% vs 16.6%; P < .01).
• Higher odds of leaving for non-job-related reasons: female staff (AOR 3.84), benefits dissatisfaction (AOR 5.42), no public health training (AOR 3.49).

Clinical Relevance: Findings are indirect for UK practice, but suggest retention strategies for early-career staff in remote or island settings (e.g. Scottish islands, overseas territories) should address family-supportive benefits and training pathways alongside pay.

Limitations: Cross-sectional self-reported intentions rather than actual turnover, and the abstract gives no sample size or response rates, limiting assessment of precision and bias.

Study Type: Cross-sectional workforce survey (pilot expansion of the national PH WINS), descriptive.

Key Question: What are the demographics, job satisfaction, burnout levels and training needs of the public health workforce in US territories and freely associated states, previously excluded from national workforce assessments?

Key Findings:

• Of 8,913 staff invited, 2,556 responded (29% overall; 19% Caribbean, 47% Pacific Islands).
• The workforce was younger and more racially and ethnically diverse than mainland comparators, with higher job satisfaction and lower burnout, despite lower formal public health training, education levels and benefits.
• Training needs were greatest in the Pacific Islands, particularly policy engagement and systems and strategic thinking.

Clinical Relevance: Although US-specific, it illustrates how excluding small or remote populations from workforce data hides need, which is relevant to NHS workforce planning in remote, island and devolved settings.

Limitations: Low and uneven response rates (19% in the Caribbean) risk non-response bias, and the abstract reports no comparative statistics or confidence intervals.

Study Type: Cross-sectional national survey (2024 Public Health Workforce Interests and Needs Survey, US), with design-adjusted descriptive and multivariable analyses.

Key Question: How do perceived workplace demands vary by rurality and individual or position characteristics among the US local public health workforce, and how do they relate to burnout and intention to leave?

Key Findings:

• Nineteen percent of the local workforce worked across four or more program categories, rising to over 30% in rural settings.
• Perceived demands (difficulty managing job demands, inability to finish work within hours, taking on out-of-role responsibilities, multi-programme working) varied by setting, individual and position characteristics.
• In all but one instance, each demand measure was associated with higher odds of burnout and intention to leave. Effect sizes and confidence intervals are not reported in the abstract.

Clinical Relevance: The pattern of rural staff covering multiple programme areas is plausibly transferable to smaller or geographically dispersed UK public health teams, though NHS and local authority structures differ, so workforce retention planning should not assume direct equivalence.

Limitations: The cross-sectional design precludes causal inference, and intention to leave is a stated intention rather than observed turnover; US-only data limit direct UK generalisability.

Study Type: Comparative mixed-methods policy analysis (text analysis and qualitative coding of programme documents) across 9 communities.

Key Question: Which community emissions reduction programme (CERP) strategies have been implemented across California's AB 617 communities, and which approaches best support public health goals?

Key Findings:

• More than 800 strategies were categorised into 25 comparable groups, showing substantial variation in what communities adopted.
• Strategies were assessed on health protection capacity, adoption pathway and ease of implementation, using funding expenditure as a proxy for progress.
• Success was most strongly associated with creative programme development, interagency coordination and community capacity. The abstract gives no effect sizes or quantitative associations.

Clinical Relevance: The findings offer transferable lessons for UK place-based work on air quality inequalities, such as Clean Air Zones and local authority action plans, particularly on community co-design and cross-agency working.

Limitations: Expenditure is a weak proxy for progress, and the abstract reports no measured emissions, exposure or health outcomes, so effectiveness cannot be inferred.

Study Type: Population-based birth cohort study using linked administrative records (vital statistics and child protection data), with a matched case-comparison analysis (1:4).

Key Question: Is the level of child protection system (CPS) involvement during childhood associated with risk of adolescent overdose death?

Key Findings:

• Of 747 adolescent overdose decedents, 69.9% had at least one CPS referral, compared with 34.6% of matched comparison adolescents.
• Any CPS history was associated with a 5-fold higher overdose death rate (IRR 5.36; 95% CI 4.41–6.51), with elevated rates at every level of involvement (referral, substantiated referral, foster care).

Clinical Relevance: Findings support treating any CPS contact, not just substantiation or care entry, as a risk marker, which is relevant to UK children's social care and CAMHS/substance misuse service coordination, though the US Medicaid context limits direct transferability.

Limitations: Observational design cannot establish causation, and the abstract does not report adjustment for confounders such as family socioeconomic circumstances, parental substance use, or mental health history.

Study Type: Quasi-experimental difference-in-differences analysis of repeated cross-sectional survey data (American Community Survey, 2016-2023; n = 100,434).

Key Question: Did continuous Medicaid eligibility during the COVID-19 public health emergency affect fertility among low-income US women without dependent children?

Key Findings:

• No overall change in birth prevalence in states that had expanded Medicaid (exposed) versus those that had not (unexposed): -0.1 percentage points (95% CI -1.1 to 0.8).
• Null results were consistent across marital status and citizenship subgroups.
• Women aged 30-34 showed a significant decrease: -2.7 percentage points (95% CI -5.1 to -0.2), a 33% relative fall from a baseline of 8.1%.

Clinical Relevance: Findings are indirect for the NHS, where coverage is universal, but they suggest that insurance continuity alone has little population-level effect on fertility, which is relevant to commentary on healthcare access and reproductive outcomes.

Limitations: The 30-34 subgroup finding is one of several subgroup analyses with a wide confidence interval (lower bound near zero), so it may reflect chance or unmeasured pandemic-era confounding.
