... Prostatectomy provides the benefit of high prostate cancer–specific 20-year survival rates; even when performed by skilled surgeons, however, it carries significant risks of sexual, bladder, and bowel dysfunction, along with less common side effects such as Dr. Bennett's.
From page 64...
... When making these decisions, patients often lack clear and understandable information on their options, the risks and benefits of each, and the actions they can take in managing their condition. For those working in the health care enterprise, the current complexity of clinical decision making challenges human cognitive capacity to manage information.

... Adherence to five separate sets of clinical practice guidelines for the woman's five diseases could result in adverse interactions between her medications, or a medication for one disease could exacerbate the symptoms of another (see Table 2-1 for potential treatment interactions)

... Each clinician managed a median of approximately 250 unique primary diagnoses, 280 unique medications, and 130 unique laboratory tests. These figures were even higher for those clinicians in primary care fields, such as internal medicine, who managed a median of 370 unique

... While strategies to overcome cognitive errors in clinical decision making are beginning to be identified (Croskerry, 2002, 2003; Redelmeier, 2005) , time and resource constraints, increasing stress among providers, and growing complexity are all barriers to overcoming the risks of these errors.
From page 74...
... . The pace at which new knowledge is produced outstrips the ability of any individual clinician to read, remember, and manage information that could inform clinical practice.
From page 75...
... . Similarly, the results of major clinical trials often are not implemented in regular clinical practice, as was the case for the Occluded Artery Trial (OAT)

... Since then, knowledge of the molecular drivers of non-small-cell lung cancer has increased dramatically; by 2009, nine different driver mutations had been identified (IOM, 2011)

... Indeed, as noted earlier, this growth in knowledge may be expanding beyond the limits of what human cognitive capacity can handle. Conclusion 2-1: Diagnostic and treatment options are expanding and changing at an accelerating rate, placing new stresses on clini cians and patients, as well as potentially impacting the effectiveness and efficiency of care delivery.

... Further, while patients with the highest health care costs represent only 5 percent of the total population, their care consumes 50 percent of total health care resources. ADMINISTRATIVE COMPLEXITY Administrative complexity, including complicated workflows and fragmented financing, exacerbate the challenges posed by the clinical complexity described above.
From page 80...
... Inefficient workflows also restrict the amount of time nurses can spend directly caring for patients; indeed, it has been found that hospital nurses spend only about 30 percent of their time in direct patient care (Hendrich et al., 2008; Hendrickson et al., 1990; Tucker and Spear, 2006)

... This frequent turnover in insurance relationships has implications for health care costs and outcomes. While many payers support preventive care and chronic care management, frequent changes in insurance enrollment lessen the incentives for investing in early interventions that can reduce long-term health care costs (Cebul et al., 2008)
