Anesthesia Liability Related to Pre-existing Conditions.

In 1985, the American Society of Anesthesiologists initiated a quality improvement closed claims analysis project for anesthetic injury to elevate patient safety. To date, there have been a total of 8954 documented claims, describing injuries contracted under sedation, regional anesthesia, or failure to attend to a patient's post-operative needs. The Closed Claims database reveals that the most highly documented health care complications were a loss of life at 2%, nerve injuries at 2%, and damage to the brain at 9%. The highest documented cases of damage from anesthesia involved regional-block-related events at 20%, followed by respiratory-related adverse effects at 17%, cardiovascular-related events at 13%, together with apparatus-linked events at 10%. Injury may result from several causes. First, multiple techniques and interventions are used during surgery, and all have potential adverse effects. Additionally, many patients scheduled for surgery have extensive past medical histories and medical comorbidities, thereby increasing their baseline risk for injury. From the Closed Claims database, improved evaluation of clinical-related implications linked to injuries within the handling of airway, sedation, non-operational room locales, obstetric anesthesia, along with chronic pain management. In summary, anesthesia departments should review outcomes of their patients on a routine basis. Assessing factors when an adverse outcome occurs may allow for changes in techniques or other anesthesia considerations to help lessen or prevent future complications.

Sleep problems and risk of cancer incidence and mortality in an older cohort: The Cardiovascular Health Study (CHS).

BACKGROUND: Sleep problems (SP) can indicate underlying sleep disorders, such as obstructive sleep apnea, which may adversely impact cancer risk and mortality. METHODS: We assessed the association of baseline and longitudinal sleep apnea and insomnia symptoms with incident cancer (N = 3930) and cancer mortality (N = 4580) in the Cardiovascular Health Study. We used Cox proportional hazards regression to calculate adjusted hazard ratios (HR) and 95% confidence intervals (CI) to evaluate the associations. RESULTS: Overall, 885 incident cancers and 804 cancer deaths were identified over a median follow-up of 12 and 14 years, respectively. Compared to participants who reported no sleep apnea symptoms, the risk of incident cancer was inversely associated [(HR (95%CI)] with snoring [0.84 (0.71, 0.99)]. We noted an elevated prostate cancer incidence for apnea [2.34 (1.32, 4.15)] and snoring [1.69 (1.11, 2.57)]. We also noted an elevated HR for lymphatic or hematopoietic cancers [daytime sleepiness: 1.81 (1.06, 3.08)]. We found an inverse relationship for cancer mortality with respect to snoring [0.73 (0.62, 0.8)] and apnea [(0.69 (0.51, 0.94))]. We noted a significant inverse relationship between difficulty falling asleep and colorectal cancer death [0.32 (0.15, 0.69)] and snoring with lung cancer death [0.56 (0.35, 0.89)]. CONCLUSIONS: The relationship between SP and cancer risk and mortality was heterogeneous. Larger prospective studies addressing more cancer sites, molecular type-specific associations, and better longitudinal SP assessments are needed for improved delineation of SP-cancer risk dyad.
