Self-referred whole-body CT imaging: current implications for health care consumers

PURPOSE

To conduct an empirical analysis of self-referred whole-body computed tomography (CT) and develop a profile of the geographic and demographic distribution of centers, types of services and modalities, costs, and procedures for reporting results.

MATERIALS AND METHODS

An analysis was conducted of Web sites for imaging centers accepting self-referred patients identified by two widely used Internet search engines with large indexes. These Web sites were analyzed for geographic location, type of screening center, services, costs, and procedures for managing imaging results. Demographic data were extrapolated for analysis on the basis of center location. Descriptive statistics, such as frequencies, means, SDs, ranges, and CIs, were generated to describe the characteristics of the samples. Data were compared with national norms by using a distribution-free method for calculating a 95% CI (P <.05) for the median.

RESULTS

Eighty-eight centers identified with the search methods were widely distributed across the United States, with a concentration on both coasts. Demographic analysis further situated them in areas of the country characterized by a population that consisted largely of European Americans (P <.05) and individuals of higher education (P <.05) and socioeconomic status (P <.05). Forty-seven centers offered whole-body screening; heart and lung examinations were most frequently offered. Procedures for reporting results were highly variable.

CONCLUSION

The geographic distribution of the centers suggests target populations of educated health-conscious consumers who can assume high out-of-pocket costs. Guidelines developed from within the profession and further research are needed to ensure that benefits of these services outweigh risks to individuals and the health care system.

Death in the intensive care nursery: physician practice of withdrawing and withholding life support

OBJECTIVE

To determine the frequency of selective nontreatment of extremely premature, critically ill, or malformed infants among all infant deaths in a level III intensive care nursery (ICN) and to determine the reasons documented by neonatologists for their decisions to withdraw or withhold life support.

METHODS

This was a descriptive study based on review of the medical records of all 165 infants who died at a university-based level III ICN during 3 years. We determined whether each death had occurred despite the use of all available technologies to keep the infant alive or whether these were withheld or withdrawn, thereby leading to the infant's death. We also determined whether neonatologists documented either "futility" or "quality of life" as a reason to limit medical interventions.

RESULTS

One hundred sixty-five infants died among the 1609 infants admitted during the study period. One hundred eight infant deaths followed the withdrawal of life support, 13 deaths followed the withholding of treatment, and 44 deaths occurred while infants continued to receive maximal life-sustaining treatment. For 90 (74%) of the 121 deaths attributable to withholding of withdrawal of treatment, physicians cited that death was imminent and treatment was futile. Quality-of-life concerns were cited by the neonatologists as reasons to limit treatment in 62 (51%). Quality of life was the only reason cited for limiting treatment for 28 (23%) of the 121 deaths attributable to withholding or withdrawal of treatment.

CONCLUSIONS

The majority of deaths in the ICN occurred as a result of selective nontreatment by neonatologists, with few infants receiving maximal support until the actual time of death. Neonatologists often documented that quality-of-life concerns were considered in decisions to limit treatment; however, the majority of these decisions were based on their belief that treatment was futile. Prospective studies are needed to elucidate the determinants of neonatologists' practice decisions of selective nontreatment for marginally viable or damaged infants.
