Incremental adoption of information security in health-care organizations: implications for document management.

The incremental adoption of electronic media in U.S. health care has created increased risk of security and privacy violations in provider organizations. Protective regulatory efforts have been proposed to address ineffective security of patient information, with severe noncompliance penalties. Using data from a nationwide survey of health information managers, this study examines how industry-wide knowledge management trends may influence the degree of security program adoption in health-care organizations. Results suggest that significant nonadoption of mandated security measures continues to occur across the health-care industry. Paper-based systems still prevail, and computerized settings tend to have less security measures. Implications for document management and knowledge policy are discussed.

Clinical knowledge management using computerized patient record systems: is the current infrastructure adequate?

The proliferation of technology in health care, spurred by environmental factors encouraging the adoption of computerized patient records (CPRs), has led to a widely held perception of fully computerized patient information systems as the industry norm. To test the validity of this assumption, using data from a national survey of certified health information managers, we examined the CPR technology adoption rates reported by health information managers, assessing variation across practice settings, regions, and organizational types. Results show that significant nonadoption, and regional variation, exists in the implementation of CPRs. Overall, nonuniform diffusion of computerized health information technology was found, despite national mandates that promote and at times require uniform adoption. A significantly greater number of hospital-based patient records were computerized, compared to clinics and other practice settings. Managers were frequently found to maintain duplicate CPRs and paper-based patient record systems, even after the initial implementation period. Nonuniform regional CPR adoption and redundant paper-based systems were found to be a common practice in medical systems, due in part to cultural factors, mistrust of computerized data, and lack of technology training and knowledge.

Counseling versus antidepressant therapy for the treatment of mild to moderate depression in primary care: economic analysis.

OBJECTIVE: To compare the cost-effectiveness of generic psychological therapy (counseling) with routinely prescribed antidepressant drugs in a naturalistic general practice setting for a follow-up period of 12 months. METHODS: Economic analysis alongside a randomized clinical trial with patient preference arm. Comparison of depression-related health service costs at 12 months. Cost-effectiveness analysis of bootstrapped trial data using net monetary benefits and acceptability curves. RESULTS: No significant difference between the mean observed costs of patients randomized to antidepressants or to counseling (342 pounds sterling vs 302 pounds sterling , p = .56 [t test]). If decision makers are not willing to pay more for additional benefits (value placed on extra patient with good outcome, denoted by K, is zero), then we find little difference between the treatment modalities in terms of cost-effectiveness. If decision makers do place value on additional benefit (K > 0 pounds sterling), then the antidepressant group becomes more likely to be cost-effective. This likelihood is in excess of 90% where decision makers are prepared to pay an additional 2,000 pounds sterling or more per additional patient with a good global outcome. The mean values for incremental net monetary benefits (INMB) from antidepressants are substantial for higher values of K (INMB = 406 pounds sterling when K = 2,500 pounds sterling). CONCLUSION: For a small proportion of patients, the counseling intervention (as specified in this trial) is a dominant cost-effective strategy. For a larger proportion of patients, the antidepressant intervention (as specified in this trial) is the dominant cost-effective strategy. For the remaining group of patients, cost-effectiveness depends on the value of K. Since we cannot observe K, acceptability curves are a useful way to inform decision makers.

Tackling teenage turmoil: primary care recognition and management of mental ill health during adolescence.

This paper examines how primary care can improve for teenagers who are experiencing mental or emotional turmoil. This is an important health issue because at least 15% of teenagers experience mental health problems at any one time, there are indications that this proportion is rising, and there is evidence that suicide rates are rising in young people. The paper discusses how troubled teenagers can be identified, cared for and managed by primary care providers within the UK, although some of the information presented is from other countries. It identifies inter-relationships with other health behaviours and risk factors. The GP's role in assessing a troubled teenager is discussed, as well as a consideration of individual and contextual issues to frame a "triple" diagnosis, i.e. a diagnosis simultaneously in biomedical, individual and contextual terms. A review of present knowledge of management is presented. The paper concludes that there are several deficiencies at present, namely a lack of identification of teenage distress, a lack of training for GPs in teenage health, a lack of a research base, a lack of resources and finally a lack of information provided by any teenagers who have experienced turmoil and could give useful insights into their experience.
