RESULTS: A total of 2144 patients were reviewed, and 74 were found to have dural tears occurring during or before surgery. Incidental durotomy occurred at the time of surgery in 66 patients (3.1% overall incidence).Incidence varied according to the specific procedure performed but was highest in the group that underwent revision surgery.ncidental durotomy occurred at the time of surgery in 66 patients (3.1% overall incidence).

âGDP is a flawed measure of human welfareâ. GDP has always been a measure of output, not of welfare. Using current prices, it measures the value of goods and services produced for final consumption, private and public, present and future.n a recent paper submitted as evidence to the LSEâs Growth Commission, I consider three common criticisms of GDP as a target of policy and explain why I think they are wrong (Oulton, 2012a): 1  The first criticism is that GDP is hopelessly flawed as a measure of human welfare.
When economists talk about economic growth they are measuring the change in gross domestic product. Lay criticisms of GDP are often based on the indisputable observation that there is more to life than economics and material goods. GDP omits work done in the home, mostly by women.t does not tell us how happy we are or how fulfilling are our lives. These objections are valid but largely beside the point. GDP is a measure of the productive performance of the economy. How that productive potential is used is an important subject but a different subject, and only partly an economic question.
