Getting the right diagnosis is a key aspect of health care - it provides an explanation of a patient's health problem and informs subsequent health care decisions. The diagnostic process is a complex, collaborative activity that involves clinical reasoning and information gathering to determine a patient's health problem. According to Improving Diagnosis in Health Care, diagnostic errors-inaccurate or delayed diagnoses-persist throughout all settings of care and continue to harm an unacceptable number of patients. It is likely that most people will experience at least one diagnostic error in their lifetime, sometimes with devastating consequences. Diagnostic errors may cause harm to patients by preventing or delaying appropriate treatment, providing unnecessary or harmful treatment, or resulting in psychological or financial repercussions. The committee concluded that improving the diagnostic process is not only possible, but also represents a moral, professional, and public health imperative. Improving Diagnosis in Health Care, a continuation of the landmark Institute of Medicine reports To Err Is Human (2000) and Crossing the Quality Chasm (2001), finds that diagnosis-and, in particular, the occurrence of diagnostic errorsâ€"has been largely unappreciated in efforts to improve the quality and safety of health care. Without a dedicated focus on improving diagnosis, diagnostic errors will likely worsen as the delivery of health care and the diagnostic process continue to increase in complexity. Just as the diagnostic process is a collaborative activity, improving diagnosis will require collaboration and a widespread commitment to change among health care professionals, health care organizations, patients and their families, researchers, and policy makers. The recommendations of Improving Diagnosis in Health Care contribute to the growing momentum for change in this crucial area of health care quality and safety.

This report to the California Energy Commission's Public Interest Energy Research Program (PIER) helps Home Performance Contractors train their crews to achieve superior results in home energy retrofits. The book was updated and expanded in December of 2012 to include the impressive measured results from 15 home energy retrofits in Redding, California that were accomplished using the principles and practices outlined in this report. Homeowners may also find this information useful, when they want to understand the techniques that regularly achieve utility bill savings of 40 to 70% on an annual basis. This approach-called Measured Home Performance-is different from other means of saving energy. Most importantly, all of the home's energy features are redesigned and improved at the same time, so the synergies take effect immediately. Next, measurements are taken all the way through the process, to ensure that both the redesign and the installation are excellent. Improved comfort and energy savings are assured by high-tech field measurements, taken by the craftspeople themselves rather than by 3rd-party auditors. This process provides real-time feedback to the real decision makers-the technicians who do the work. Measurements of critical parameters like duct air leakage, while-house air leakage, supply air flow at each grill, CO concentration & draft pressure of combustion appliances and superheat and subcooling of the AC equipment make the installation quality-good or poor-are instantly clear to the crews. They can fix any shortcomings on the spot, rather than waiting days or weeks for 3rd-party testing results. Craftspeople measuring key parameters as they work transforms the workplace. Measured quality not only ensures successful results for the homeowners, it self-trains crew members in the field, where they learn more quickly than in the classroom. At the end of every day, workers know when they have achieved excellent results-a powerful motivator that works to everybody's benefit.
