“Natural History” of Health Technology Assessment (HTA)
Emergence Focus on developing an initial capacity to meet modest demands from a small group of like-minded decision makers
Consolidation HTA transitions from a venture investment by health care systems to an operational feature
Expansion The need for HTA becomes widely recognized and promoted by high-level figures at the government or policy level

Health Care Quality
Source: Institute of Medicine. Crossing the Quality Chasm. Washington, D.C.: National Academies Press; 2001.
Safe – avoiding injury to patients from care that is intended to help them
Timely – reducing waits and harmful delays
Effective - providing services based on scientific knowledge to all who could benefit and refraining from providing services to those not likely to benefit (avoiding overuse and underuse)
Equitable - providing care that does not vary in quality because of personal characteristics such as gender, ethnicity, geographical location, and socioeconomic status
Efficient – avoiding waste
Patient Centered - providing care that is respectful of and responsive to individual patient preferences, needs, and values

Isolated Coronary Artery Bypass (CABG) Surgery at Micro (Individual Surgeon) Level: Equity
Mortality rates by race at the surgeon level may not be informative due to the small number of patients across different racial groups
While the probability of other patient characteristics (e.g., socioeconomic status) related to CABG surgery may be meaningful, we do not have this data

• Micro • Large variability in volume among surgeons
• What is the minimum annual volume that is safe for a surgeon to perform?
• From a statistical analysis perspective, it is difficult to classify individual surgeons as high-mortality outliers
Health Care Policy Implications
![Page 56: 01 ballard](https://reader031.vdocuments.site/reader031/viewer/2022020101/5453ba74b1af9f88228b4764/html5/thumbnails/56.jpg)

• Meso • Should a given health care system restrict
performance of CABG to hospitals of a certain volume?
• What percentage of hospitals are high-volume, medium-volume, or low-volume for CABG surgery?
• What should be done about high-volume hospitals with poor CABG surgery outcomes?
Health Care Policy Implications

• Macro • How many Dallas-Fort Worth hospitals should
be performing CABG?
• Whose responsibility is it to decide whether to close a cardiac surgery program? (Should this be decided by a health care system, by state or national regulation, or by another method?)

Adjusted Mortality Rate and Volume
Conclusions
1. Mean mortality rate was lower in Italy than in TX
2. In TX lower adjusted mortality rate was associated with higher volume 3. The three highest mortality hospitals in Italy had monthly volumes above the average monthly volume
4. Monthly volume was higher in Italy than in TX
5. In 2002-04 TX had twice as many cardiac programs than Italy despite having half of the population than Italy

Different participation rate (100% in Texas vs 72% in Italy)
Different cohorts, data, and modeling strategies were used for the estimation of the adjusted mortality rates

Discussion
• While there are opportunities in the US to close low-volume coronary artery bypass graft (CABG) programs, are there opportunities in Italy to consolidate low-volume to medium-volume CABG programs?
• Both Texas and Italy have some high-volume centers with high mortality – do they need new leadership or some other intervention?
