A systems approach to identifying inappropriate use of controlled substances: the need for balance.

BACKGROUND: The diversion, abuse, and inappropriate use of controlled substances remain of concern among health care practitioners, insurers, and policy makers in the United States. The principle of "balance" represents a need to establish a system of control to prevent abuse, trafficking, and diversion of controlled substances, while ensuring their medical availability for legitimate patients. ADMINISTRATIVE DATABASES TO STUDY OUTCOMES AND QUALITY OF CARE: Some models employ pattern recognition within administrative health databases, for example, to examine outcomes and quality of medical care and monitor fraudulent behaviors and inappropriate medical care. Patients' use of resources or variations in practitioners' practice patterns can be examined. A SYSTEMS APPROACH TO ADDRESS INAPPROPRIATE USE OF CONTROLLED SUBSTANCES: A systems approach would require collaboration with medical and pharmacy directors, systems analysts, coding experts, legal experts, and clinicians to develop the claims-based model. Once a patient and/or practitioner with possible diversion or abuse are identified, a second step is required to distinguish inappropriate and appropriate behaviors and medical care. CONCLUSION: Programs to detect misuse of controlled substances must be validated through clinical research, and a consensus should be reached as to what constitutes a breach of accepted medical practice.

Therapy switching in patients receiving long-acting opioids.

BACKGROUND: Patterns of therapy switching in patients receiving long-acting opioids have not been well documented. OBJECTIVE: To compare therapy switching among patients beginning treatment with controlled-release (CR) oxycodone, transdermal fentanyl, or CR morphine sulfate. METHODS: Using a US healthcare claims database, we identified patients beginning treatment with CR oxycodone, transdermal fentanyl, or CR morphine sulfate between July 1, 1998, and December 31, 1999. We compiled claims for each patient for 6 months following therapy initiation and compared the incidence of therapy switching among the 3 groups. We also estimated total healthcare charges for patients who switched therapy versus those who did not. RESULTS: We identified 1931, 668, and 449 patients beginning therapy with CR oxycodone, transdermal fentanyl, and CR morphine sulfate, respectively; 16.7%, 25.0%, and 35.9%, respectively, had cancer. For patients without cancer, rates of therapy switching at 6 months were 10.6% (CR oxycodone), 19.0% (transdermal fentanyl), and 26.0% (CR morphine sulfate); for those with cancer, rates were 23.8%, 24.6%, and 29.8%, respectively. Multivariate hazard ratios (vs CR morphine sulfate) for therapy switching in patients without cancer were 0.36 (95% CI, 0.27 to 0.47) for CR oxycodone and 0.69 (0.51 to 0.94) for transdermal fentanyl; for those with cancer, corresponding hazard ratios were 0.72 (0.50 to 1.03) and 0.76 (0.50 to 1.16). Total healthcare charges were significantly (p < 0.01) higher for patients who switched therapy than those who did not (23,965 US dollars vs 14,299 US dollars in pts. without cancer; 58,259 US dollars vs 39,618 US dollars for those with cancer). CONCLUSIONS: Patients without cancer who receive CR oxycodone or transdermal fentanyl are less likely to switch therapy than those receiving CR morphine sulfate. Total healthcare charges are higher for patients who switch therapy.

Opioid use and health care charges at the end of life in patients with metastatic cancer.

Opioid use and health care charges during the final year of life in patients with metastatic cancer who received controlled-release oxycodone (CRO), transdermal fentanyl (TF), or controlled-release morphine sulfate (CRM) were examined in the following study. A total of 704 patients were identified who met study entry criteria; CRO, TF, or CRM was the first-received long-acting opioid (LAO) during the last year of life for 36% (N = 250), 29% (N = 203), and 36% (N = 251) of study subjects, respectively. On average, patients initiated LAO therapy three to four months before death. One-half of patients received less than 60 days of LAO therapy. Mean total health care charges in the final year of life were dollars 84,572 for patients receiving CRO, dollars 90,935 for patients receiving TF, and dollars 76,446 for patients receiving CRM. Patients receiving TF started LAO therapy closer to their date of death, and had significantly higher hospitalization charges than did patients receiving CRO and CRM.

Identifying controlled substance patterns of utilization requiring evaluation using administrative claims data.

OBJECTIVES: To develop a systems approach to identify, for further evaluation, patients with potential controlled substance misuse or mismanagement using software queries applied to administrative health claims data. STUDY DESIGN: Retrospective validation of the system using insurance claims. PATIENTS AND METHODS: Data from administrative health claims databases representing nearly 7 million individuals younger than 65 years were used by multidisciplinary expert panels to develop and validate controlled substance patterns of utilization requiring evaluation (CS-PURE) criteria. RESULTS: Thirty-four CS-PURE queries were developed in SAS and applied to administrative claims records to identify patients with potential controlled substance misuse or mismanagement. From these, we identified 10 CS-PURE with the highest expert agreement that intervention was warranted. Expert panel agree, ment that CS-PURE correctly identified cases ranged from 48% to 100%, with at least 50% agreement in 9 of 10 CS-PURE. The prevalence rates for CS-PURE ranged from 0.001% to 0.252%. This translates to identifying between 5 and 1116 patients for individual CS-PURE in a 500 000-member health plan. CONCLUSIONS: We developed and empirically validated a group of queries using CS-PURE to identify patients with potential controlled substance misuse or mismanagement that would warrant further evaluation by the treating physician, a quality assurance function, or the medical director. Claims-based CS-PURE identification is generalizable to most health insurers with access to medical and pharmaceutical claims records. Although CS-PURE are not direct measures of misuse, they can direct attention to potential problems to determine if intervention is needed.

Development of a metric for a day of manageable pain control: derivation of pain severity cut-points for low back pain and osteoarthritis.

The objective of this study was to adapt the concept of 'episode-free day', a metric for measuring symptom relief in daily units, to the clinical outcome literature for persistent pain. The episode-free day metric is widely used in other medical literature, but no analogous measure exists in pain literature. Prior focus groups with this population suggested that a 'Day of Manageable Pain Control' was an appropriate name for the metric. In the present study, in order to derive a statistical criterion for 'Manageable Day', we used Serlin et al.'s (Pain 61 (1995) 277) cut-point derivation method to derive a single cut-point on a 0-10 scale of average pain that divided groups with significant persistent pain optimally on pain-related functional interference. Participants were 194 patients with moderate-severe low back pain (n=96) or osteoarthritis (n=98). For both patient samples, '5' was the cut-point that optimally distinguished groups on pain-related interference. '5-8' and '5-7' were double cut-point solutions that optimally divided LBP and OA samples into three categories (e.g. lowest, medium and highest average pain), respectively. Derived cut-points were confirmed using a variety of measures of functional disability. Together with research that showed that average pain ratings of approximately 5 and below permit increased function and quality of life in patients with moderate to severe low back pain and osteoarthritis, our findings provide support for the use of 0-5 on a 0-10 numeric average pain severity scale as one possible criterion for a Manageable Day.

Use of oral and transdermal opioids among patients with metastatic cancer during the last year of life.

This study documents the use of oral and transdermal opioids among patients with metastatic cancer during their final year of life. Using a large, integrated health-insurance claims database, we identified all patients who had metastatic lung, breast, colorectal, prostate, or breast cancer and who also died in 1998 or 1999. We then examined all pharmacy claims for these patients over their final 12 months of life. A total of 2,132 patients were identified who met study entrance criteria. Among patients with bone metastases (n=717), 86.9% received opioids at some point during their final year of life; 71.2% of those without bone metastases (n=1,415) received them. Corresponding figures for long-acting opioids were 52.9% and 23.5%. Coverage ratios (total days supplied/total noninstitutionalized days) for any opioids and long-acting opioids were 25.1% and 12.5%, respectively, among patients with bone metastases, and 13.9% and 4.2% for those without bone metastases. During the final month of life, these ratios were 50.8% and 31.3%, and 28.7% and 13.1%. These relatively low rates of opioid use among patients with metastatic cancer in their final year of life suggest that pain in many cases may be suboptimally treated.

Care management for persistent pain: an introduction.

Persistent pain is a frequently occurring condition with significant economic, clinical, and humanistic implications, for both individuals and society. Current literature, however, points to unresolved issues with regard to its identification, assessment, diagnosis, and treatment, and a number of suggestions have been made for improving the quality of care for pain sufferers. Because persistent pain shares many of the salient features of other chronic conditions such as diabetes and congestive heart failure, it is reasonable to believe that the adoption of a coordinated approach to care management could substantially improve the quality of care. Several strategies--including identification, appropriate referral, education, and planning--can and should be implemented to offer comprehensive, individualized treatment alternatives that are not currently available and that improve patient outcomes, including quality of life.
