KELeadership Evidence LabExecutive research dashboard

Critical integrative synthesis

Evidence, method, and interpretive discipline

The report combines independent healthcare-leader research with a rapid critical review that tests mechanisms, limitations, counterfactuals, and the costs of turnover.

Two-stream evidence design
Stream 1 supplies the five-to-eight-year finding. Stream 2 tests and qualifies the thesis with peer-reviewed evidence.

tenure

Hambrick & Fukutomi (1991)

Tenure mechanisms change over time.

Conceptual, not hospital-specific.
tenure

Miller (1991)

Long tenure can weaken organization-environment fit.

tenure

Brochet et al. (2021)

Firm value showed an average hump-shaped tenure relationship.

Firm value is not hospital performance.
variety

Crossland et al. (2014)

Career variety was associated with strategic novelty.

Novelty is not necessarily better performance.
variety

Dries et al. (2012)

Career variety was positively associated with learning agility.

Small, noncausal field design.
healthcare

Spanos et al. (2024)

Adaptation and collaboration dominated future competency themes.

Mixed academic and gray evidence.
healthcare

Varga et al. (2023)

Trust depends on ethical, supportive, accessible leadership.

Eighteen studies met inclusion criteria.
turnover

Schepker et al. (2017)

Succession disrupted short-term performance.

Cross-industry evidence.
turnover

Hermes et al. (2025)

Hospital CEO turnover can impose performance and failure risks.

Heterogeneous measures and designs.
turnover

Leggat & Balding (2019)

Leadership churn can weaken quality governance.

Matched-field evidence supports a learning mechanism, not a universal causal claim.

Percentages calculated from counts reported by Spanos et al. (2024); the groups should not be pooled as prevalence estimates.
Supported

Tenure builds local knowledge; succession can disrupt; adaptation matters.

Plausible

Variety may strengthen cross-context learning and trust formation.

Proposed

The model, matrix, and PLEI require validation.

Rejected

Career pattern alone cannot rank every leader.
