Determinants of Cost among People Who Died in VA Nursing Homes

Direct medical costs of COPD--an excess cost approach based on two population-based studies

AIM

While it is known that severe COPD has substantial economic consequences, evidence on resource use and costs in mild disease is scarce. The objective of this study was to investigate excess costs of early stages of COPD.

METHODS

Using data from two population-based studies in Southern Germany, current GOLD criteria were applied to pre-bronchodilator spirometry for COPD diagnosis and staging in 2255 participants aged 41 to 89. Utilization of physician visits, hospital stays and medication was compared between participants with COPD stage I, stage II+ (II or higher) and controls. Costs per year were calculated by applying national unit costs. In controlling for confounders, two-part generalized regression analyses were used to account for the skewed distribution of costs and the high proportion of subjects without costs.

RESULTS

Utilization in all categories was significantly higher in COPD patients than in controls. After adjusting for confounders, these differences remained present in physician visits and medication, but not in hospital days. Adjusted annual costs did not differ between stage I (€ 1830) and controls (€ 1822), but increased by about 54% to € 2812 in stage II+.

CONCLUSION

The finding that utilization and costs are considerably higher in moderate but not in mild COPD highlights the economic importance of prevention and of interventions aiming at early diagnosis and delayed disease progression.

Service implications of providing intensive monitoring during high-risk periods for suicide among VA patients with depression

OBJECTIVES

Department of Veterans Affairs (VA) patients in depression treatment have high suicide rates after psychiatric hospitalization, antidepressant starts, and dosage changes. Policy makers have recommended closer monitoring during these periods to reduce suicide. This study assessed the frequency of high-risk periods in clinical settings, the levels of monitoring provided during these periods, and the estimated costs of providing monitoring consistent with the most stringent Food and Drug Administration recommendation for treatment periods after antidepressant change (seven visits in the first 12 weeks).

METHODS

Monitoring visits were identified in the 12-week period after antidepressant starts and dosage changes and after discharge from psychiatric hospitalization for 100,000 randomly selected VA patients in depression treatment between April 1, 1999, and September 30, 2004. Incremental costs of providing intensive monitoring were estimated by using VA Health Economics Resource Center average cost data.

RESULTS

Patients averaged less than one high-risk period each year. They completed an average of 2.4 monitoring visits during the 12-week period after antidepressant treatment events and 4.9 visits after psychiatric hospitalization. Providing intensive monitoring would cost an additional $408-$537 for each high-risk period after antidepressant treatment events and $313-$341 for each high-risk period after psychiatric hospitalization. During fiscal year 2004 providing intensive monitoring during all high-risk periods would have cost an additional $183-$270 million. Providing intensive monitoring only after psychiatric hospitalizations would have cost an additional $15-$17 million.

CONCLUSIONS

Providing intensive monitoring for VA patients in depression treatment during all high-risk periods for suicide would require substantial services reorganization and incremental expenditures. Modest expenditures would support intensive monitoring during the highest-risk period that follows psychiatric hospitalization.
