Patient care process history

If the chemical-imbalance theory is wrong, and if depression is not a brain disease, how is it produced and how can it be prevented and treated One way to look for clues is to examine the process by which we were misled into the realm of chemistry. There is a culprit hiding in the history of the chemical-imbalance theory - a culprit that is guilty of leading doctors and patients astray over and over again in the history of medicine. The culprit is the placebo effect, and its darker twin, the nocebo effect. Depressed people got better when given MAO and reuptake inhibitors as antidepressants, and this led researchers to conclude that depression must be caused by a chemical deficiency. But much (if not all) of that improvement turns out to be a placebo effect. So to understand depression and how it might be treated effectively, we need to examine the placebo effect more carefully. That is the topic of the next two chapters. 

The mechanisms by which thiazides affect erectile dysfunction or libido are unclear, but it has been suggested that they have a direct effect on vascular smooth muscle cells or reduce the response to catecholamines. Sexual dysfunction does not appear to be mediated by either a low serum potassium concentration or a low blood pressure. Since sexual dysfunction can adversely affect the quality of life of hypertensive patients, physicians or health-care providers should take an accurate baseline sexual history and monitor sexual status for changes during therapy. If there are significant changes in sexual function, diuretic therapy can be withdrawn and an alternative drug class substituted. However, not uncommonly sexual dysfunction will persist despite withdrawal of the diuretic, suggesting that elements of the hj pertensive state itself contribute to the process. 

CPAs can be written as process specific, or disease-state specific, or both. Process documents describe the routine duties of the pharmacist in global terms e.g., write prescriptions, order laboratory tests needed to monitor medication, order certain radiological tests, take medication histories, record information in the medical record, order consults, etc. Disease specific CPAs give examples of the specific patient populations the pharmacist will see, and may include protocols for patient management. These CPAs may describe comprehensive, interim-care, and unscheduled or acute-care practice models. 

The arguments offered above call for caution and the careful, however scientifically sound, evaluation of the safety of food items for human consumption. Close toxicological and pharmacological surveillance of nutritional products with additives and/or the history of chemical or physical processing is of paramount importance. The importance of this surveillance is demonstrated most convincingly by observations made recently in the field of hyperalimentation. Here the patient, deprived of the ability of oral food intake, is dependent on the intravenous infusion of solutions of essential amino acids. For solution stabilization sodium bisulfite was added. This presumed preservative, however, reacts with tryptophan (20) with the formation of products which affect liver tissue adversely (21). 

The most complex driving forces in the evolution of healthcare delivery are physicians and patients resistance and readiness to accept a "different" way of practicing medicine. On one side the physician, as a patient advocate, is eager to implement various aspects of eHealth however, at the same time, they are reluctant to change beliefs that online services may depersonalize the patient-physician relationship. This coupled with the absence of information usually obtained during clinical evaluation deprives the physician of some important decision-making inputs used in the diagnostic process. There are concerns that if a patient chooses to be consulted by the quickest available physician (online), this will undermine the importance of patient history and will reduce the quality of care.
