Should operations be regionalized? The empirical relation between surgical volume and mortality.
The mortality of open-heart surgery, vascular surgery, transurethral resection of the prostate, and coronary bypass decreased with increasing number of operations, and the value of regionalization for certain operations is supported.

Market areas are compared based on various descriptions using data on California hospitals and patient discharge abstracts to provide a framework for evaluating which definitions of hospital market areas are suitable for various types of analyses.
The volume-outcome relationship: practice-makes-perfect or selective-referral patterns?
Using data for 17 categories of patients from a sample of over 900 hospitals, a simultaneous-equation model is used and suggests that the relative importance of the practice or referral explanation varies by diagnosis or procedure, in ways consistent with clinical aspects of the various patient categories.
Correlation of Travel Time on Roads versus Straight Line Distance
The authors' outlier analyses show some exceptions, however, so this relationship may not hold for studies focusing on specific hospitals, very small numbers of hospitals, or studies in dense urban areas with high congestion and reliance on surface streets.
The impact of hospital market structure on patient volume, average length of stay, and the cost of care.
Managed care plan performance since 1980. A literature analysis.
The evidence does not support the hypothesis that prepaid group practice or staff model health Maintenance organizations are more effective than individual practice association or network model health maintenance organizations.
Does managed care lead to better or worse quality of care?
Evidence on managed care plan performance from recently published peer-reviewed studies showed an equal number of significantly better and worse HMO results, compared with non-HMO plans, but in several instances, Medicare HMO enrollees with chronic conditions showed worse quality of care.
Beyond Consent: Building Trusting Relationships With Diverse Populations in Precision Medicine Research
Several considerations for research institutions seeking to cultivate long-term, trusting relationships with patients are suggested: address the role of history and experience on trust, engage concerns about potential group harm, address cultural values and communication barriers, and integrate patient values and expectations into oversight and governance structures.
The Impact of Poor Health on Earnings

- 1 February 1975
This analysis not only provides estimates of the effect of health on each component of earnings, but also the aggregate earnings loss attributable to long term disability 23 billion dollars in 1966.
The Relation Between Surgical Volume and Mortality: An Exploration of Causal Factors and Alternative Models
- H. Luft
- MedicineMedical Care
- 1 September 1980
Multiple regression techniques are used to explore the role of other potentially important variables and alternative interpretations of the volume-mortality relationship and their relative importance varies with the procedure in ways that are consistent with anticipated referral patterns.
