The primary study objective is to conduct a prospective, randomized controlled clinical trial that compares the effectiveness of two approaches for delivering smoking cessation treatment for veterans with posttraumatic stress disorder (PTSD). An approach where smoking cessation treatment is integrated into mental health care for PTSD and delivered by mental health providers (experimental condition) will be compared to specialized smoking cessation clinic referral (VA's usual standard of care).

Secondary study objectives are to (a) compare the cost outcomes and cost-effectiveness of IC versus USC, (b) identify treatment process variables that explain (mediate) observed differences in smoking abstinence rates for the two study conditions, and (c) determine whether cessation from smoking is associated with worsening of symptoms of PTSD and/or depression.

Objective: Early identification of HIV infection is critical for patients to receive life-prolonging treatment and risk-reduction counseling. Understanding HIV screening practices and barriers to HIV testing is an important prelude to designing successful HIV screening programs. Our objective was to evaluate current practice patterns for identification of HIV.

Methods: We used a retrospective cohort analysis of 13,991 at-risk patients seen at 4 large Department of Veterans Affairs (VA) health-care systems. We also reviewed 1,100 medical records of tested patients. We assessed HIV testing rates among at-risk patients, the rationale for HIV testing, and predictors of HIV testing and of HIV infection.

Results: Of the 13,991 patients at risk for HIV, only 36% had been HIV-tested. The prevalence of HIV ranged from 1% to 20% among tested patients at the 4 sites. Approximately 90% of patients who were tested had a documented reason for testing.

Conclusion: One-half to two-thirds of patients at risk for HIV had not been tested within our selected VA sites. Among tested patients, the rationale for HIV testing was well documented. Further testing of at-risk patients could clearly benefit patients who have unidentified HIV infection by providing earlier access to life-prolonging therapy.

Objective: To describe the development of an instrument for assessing workforce perceptions of hospital safety culture and to assess its reliability and validity.

Data Sources/Study Setting: Primary data collected between March 2004 and May 2005. Personnel from 105 U.S. hospitals completed a 38-item paper and pencil survey. We received 21,496 completed questionnaires, representing a 51 percent response rate.

Study Design: Based on review of existing safety climate surveys, we developed a list of key topics pertinent to maintaining a culture of safety in high-reliability organizations. We developed a draft questionnaire to address these topics and pilot tested it in four preliminary studies of hospital personnel. We modified the questionnaire based on experience and respondent feedback, and distributed the revised version to 42,249 hospital workers.

Data Collection: We randomly divided respondents into derivation and validation samples. We applied exploratory factor analysis to responses in the derivation sample. We used those results to create scales in the validation sample, which we subjected to multitrait analysis (MTA).

Principal Findings: We identified nine constructs, three organizational factors, two unit factors, three individual factors, and one additional factor. Constructs demonstrated substantial convergent and discriminant validity in the MTA. Cronbach's  coefficients ranged from 0.50 to 0.89.

Conclusions: It is possible to measure key salient features of hospital safety climate using a valid and reliable 38-item survey and appropriate hospital sample sizes. This instrument may be used in further studies to better understand the impact of safety climate on patient safety outcomes.

Background: Thrombolytic therapy is controversial in patients with submassive pulmonary embolism.

Methods: We performed a cost-effectiveness analysis to compare health effects and costs of treatment with alteplase plus heparin sodium vs heparin alone in hemodynamically stable patients with pulmonary embolism and right ventricular dysfunction by developing a Markov model and using data from clinical trials and administrative sources.

Results: Based on data from a recent randomized trial, we assumed that the risk of clinical deterioration requiring treatment escalation was almost 3 times higher in patients who received heparin alone (23.2% vs 7.6%) but that the risk of death was equal in the 2 cohorts (2.7%). Based on registry data, we assumed that the risk of intracranial hemorrhage was approximately 3 times higher in patients who received alteplase plus heparin (1.2% vs 0.4%). Under these and other assumptions, thrombolysis resulted in marginally higher total lifetime health care costs ($43,900 vs $43,300) and was slightly less effective (10.52 vs 10.57 quality-adjusted life-years) than treatment with heparin alone. Thrombolysis was more effective and cost less than $50,000 per quality-adjusted life-year gained when we assumed that the baseline risk of death in the heparin group was 3 times the base-case value (8.1%) and that alteplase reduced the relative risk of death by at least 10%.

Conclusions: Available data do not support the routine use of thrombolysis to treat patients with submassive pulmonary embolism. However, thrombolysis may prove to be cost-effective in selected subgroups of hemodynamically stable patients in whom the risk of death is higher.

Background: Accumulating evidence indicates that addiction and psychiatric treatment programs that actively promote self-help group involvement can reduce their patients' health care costs in the first year after treatment, but such initially impressive effects may wane over time. This paper examines whether the positive clinical outcomes and reduced health care costs evident 1 year after treatment among substance-dependent patients who were strongly encouraged to attend 12-step self-help groups were sustained at 2-year follow-up.

Methods: A 2-year quasi-experimental analysis of matched samples of male substance-dependent patients who were treated in either 12-step-based (n=887 patients) or cognitive-behavioral (CB, n=887 patients) treatment programs. The 12-step-based programs placed substantially more emphasis on 12-step concepts, had more staff members "in recovery," had a more spiritually oriented treatment environment, and promoted self-help group involvement much more extensively than did the CB programs. The 2-year follow-up assessed patients' substance use, psychiatric functioning, self-help group affiliation, and mental health care utilization and costs.

Results: As had been the case in the 1-year follow-up of this sample, the only difference in clinical outcomes was a substantially higher abstinence rate among patients treated in 12-step (49.5%) versus CB (37.0%) programs. Twelve-step treatment patients had 50 to 100% higher scores on indices of 12-step self-help group involvement than did patients from CB programs. In contrast, patients from CB programs relied significantly more on outpatient and inpatient mental health services, leading to 30% lower costs in the 12-step treatment programs. This was smaller than the difference in cost identified at 1 year, but still significant ($2,440 per patient, p=0.01).

Conclusions: Promoting self-help group involvement appears to improve posttreatment outcomes while reducing the costs of continuing care. Even cost offsets that somewhat diminish over the long term can yield substantial savings. Actively promoting self-help group involvement may therefore be a useful clinical practice for helping addicted patients recover in a time of constrained fiscal resources.

Public-private partnerships have become a common approach to health care problems worldwide. Many public-private partnerships were created during the late 1990s, but most were focused on specific diseases such as HIV/AIDS, tuberculosis, and malaria.

Recently there has been enthusiasm for using public-private partnerships to improve the delivery of health and welfare services for a wider range of health problems, especially in developing countries. The success of public-private partnerships in this context appears to be mixed, and few data are available to evaluate their effectiveness.

This analysis provides an overview of the history of health-related public-private partnerships during the past 20 years and describes a research protocol commissioned by the World Health Organization to evaluate the effectiveness of public-private partnerships in a research context.

OBJECTIVE. To develop a set of quality indicators for the neurodevelopmental follow-up care of very low birth weight (VLBW; <1500 g) children.

METHODS. We reviewed the scientific literature on predictors of neurodevelopmental outcomes for VLBW children and the clinical practice guidelines relevant to their care after hospital discharge. An expert panel with members nominated by the American Academy of Pediatrics, the National Institute of Child Health and Human Development, the Vermont Oxford Network, and the California Children's Service was convened. We used a modified Delphi method to evaluate and select the quality-of-care indicators.

RESULTS. The panel recommended a total of 70 indicators in 5 postdischarge follow-up areas: general care; physical health; vision, hearing, speech, and language; developmental and behavioral assessment; and psychosocial issues. Of these, 58 (83%) indicators were in preventive care, 5 (7%) were in acute care, and 7 (10%) were in chronic care.

CONCLUSION. The quality indicators cover follow-up care for VLBW infants with various medical conditions. Given the elevated rates of long-term neurodevelopmental disabilities and the potential impact of poor health care, this new set of indicators provides an opportunity to assess and monitor the quality of follow-up care with the ultimate aim of improving the quality of care for this high-risk population.
