Medicare Part D Plans Greatly Increased Utilization Restrictions On Prescription Drugs, 2011-20

Drug utilization management tools can be employed to ensure that medicines are prescribed cost-effectively, but they can also be implemented in ways that reduce adherence and harm patient health. We examined trends in the prevalence of utilization restrictions on non-protected-class compounds in Medicare Part D plans during the period 2011-20, including prior authorization and step therapy requirements as well as formulary exclusions. Part D plans became significantly more restrictive over time, rising from an average of 31.9 percent of compounds restricted in 2011 to 44.4 percent restricted in 2020. The prevalence of formulary exclusions grew particularly fast: By 2020, plan formularies excluded an average of 44.7 percent of brand-name-only compounds. Formulary restrictions were more common among brand-name-only compared with generic-available compounds, among more expensive compounds, and in stand-alone compared with Medicare Advantage prescription drug plans.

Cost of Constipation: A New Look With a Focus on New Medications

GOAL

The study was designed to assess drug costs for constipation therapy and to relate costs to markers of functional status.

BACKGROUND

Secretagogues have been introduced as new agents for the treatment of constipation. Previously published modeling studies suggested that improved productivity lowers the indirect disease burden and balances the higher drug costs.

STUDY

Data were abstracted from the publicly available Medical Expenditure Panel Survey to identify adults with a functional gastrointestinal disorder who received a prescription for laxatives or secretagogues covering >2 days. Demographic data, recorded health care utilization and cost, and markers of functional status were extracted for the years from 2005 to 2017 to determine differences between participants treated with secretagogues or laxatives.

RESULTS

The cohort of 2006 persons was female predominant [67.8%; age: 56.9 (55.8-57.9) years] and spent $92.89 (75.68-110.10) for medications treating constipation. The use of secretagogues (10.3% of the cohort) was the best independent predictor of constipation treatment costs. Using quality of life measures, perceived limitations in activities or work, and absenteeism, there was no difference between participants receiving laxatives and those taking secretagogues.

CONCLUSION

Using survey data designed to be representative of the United States population, the study identified secretagogues as a key cost factor in drug treatment of constipation. The results do not support models suggesting improved role functioning offsets these higher direct expenditures. While prospective comparative studies are needed to more definitively correlate costs with direct or indirect benefits of different agents, limiting the use of more expensive medications to otherwise refractory cases may help to reign in the spiraling health care costs in this country.

Healthcare resource utilization, costs and treatment patterns in patients with bipolar disorder treated with lurasidone or cariprazine

OBJECTIVE

To compare healthcare resource utilization (HCRU), costs, and treatment adherence and persistence for patients with bipolar disorder treated with lurasidone or cariprazine.

METHODS

Adult patients with bipolar disorder who initiated lurasidone or cariprazine as monotherapy or adjunctive therapy between 1 January 2016 and 30 June 2019 were identified from the IBM MarketScan Commercial and Medicare Supplemental Database. The date of the first claim for lurasidone or cariprazine was defined as the index date. A difference-in-difference (DID) analysis, which mitigated bias by using each cohort as its own control, compared the changes in HCRU and costs from 6-months pre-treatment (baseline) to 6-months post-treatment (follow-up) between the two cohorts. Treatment adherence (medication possession ratio and proportion of days covered) and persistence (time to discontinuation) were assessed during the 6-month post-treatment period. Adjusted analyses were conducted using inverse probability of treatment weighting on HCRU, costs, and time to discontinuation.

RESULTS

A total of 16,683 patients treated with lurasidone and 4,128 patients treated with cariprazine were identified. Average age (39-40) and proportion female (68-71%) were similar between cohorts. Both cohorts had reductions in hospitalizations from baseline to follow-up, and the decrease was significantly greater for the lurasidone cohort compared to the cariprazine cohort (change in the proportions of patients with all-cause hospitalizations: -5.3% vs. -2.5%, DID = -2.8%, p<.001). The total healthcare costs increased from baseline to follow-up in both cohorts, and the increase was significantly lower for the lurasidone cohort (change in total all-cause healthcare cost per person: $3,413 vs. $4,642, DID=-$1,228, p = .022). The lurasidone cohort had significantly lower risk of discontinuing treatment (hazard ratio = 0.86, p<.001) than the cariprazine cohort.

CONCLUSIONS

Patients with bipolar disorder treated with lurasidone had greater reductions in hospitalizations from 6-months pre-treatment to 6-months post-treatment and had a lower increase in total costs compared to patients treated with cariprazine.

What Could Total Worker Health® Look Like in Small Enterprises?

Small enterprises have fewer resources, are more financially precarious, and have higher rates of occupational injury and illness compared with larger enterprises. Interventions that address the promotion of health and well-being in addition to traditional occupational safety and health hazards, a Total Worker Health® (TWH) approach, may be effective in reducing injuries and preventing illness. However, little research has examined the impact of TWH interventions in small enterprises. The aim of this research was to explore and characterize health and safety practices, policies, and programs in small Midwestern enterprises from a TWH perspective. Utilizing a case studies approach, site visits were conducted with small business, between 10 and 250 employees, from 2014 through 2016 and included workplace audits and interviews with multiple employees in varying roles within each organization. Both open and closed coding were used to identify specific themes. Eight themes emerged from the site visits: value and return on investment, organizational factors, program design, engaging employees, low-cost strategies, evaluation, and integration. These themes overlapped with both the National Institute for Occupational Safety and Health's (NIOSH) Essential Elements of TWH and the NIOSH Fundamentals. Industry sector and enterprise size also affect resources and integration of these resources. As TWH expands to organizations of all sizes, it is necessary to address the unique needs of smaller enterprises.
