Changes in Medication Utilization and Adherence Associated with Homeless Adults' Entry into Permanent Supportive Housing.

BACKGROUND: Permanent supportive housing (PSH) programs, which have grown over the last decade, have been associated with changes in health care utilization and spending. However, little is known about the impact of such programs on use of prescription drugs critical for managing chronic diseases prevalent among those with unstable housing. OBJECTIVE: To evaluate the effects of PSH on medication utilization and adherence among Medicaid enrollees in Pennsylvania. DESIGN: Difference-in-differences study comparing medication utilization and adherence between PSH participants and a matched comparison cohort from 7 to 18 months before PSH entry to 12 months post PSH entry. SUBJECTS: Pennsylvania Medicaid enrollees (n = 1375) who entered PSH during 2011-2016, and a propensity-matched comparison cohort of 5405 enrollees experiencing housing instability who did not receive PSH but received other housing services indicative of episodic or chronic homelessness (e.g., emergency shelter stays). MAIN MEASURES: Proportion with prescription fill, mean proportion of days covered (PDC), and percent adherent (PDC ≥ 80%) for antidepressants, antipsychotics, anti-asthmatics, and diabetes medications. KEY RESULTS: The PSH cohort saw a 4.77% (95% CI 2.87% to 6.67%) relative increase in the proportion filling any prescription, compared to the comparison cohort. Percent adherent among antidepressant users in the PSH cohort rose 7.41% (95% CI 0.26% to 14.57%) compared to the comparison cohort. While utilization increased in the other medication classes among the PSH cohort, differences from the comparison cohort were not statistically significant. CONCLUSIONS: PSH participation is associated with increases in filling prescription medications overall and improved adherence to antidepressant medications. These results can inform state and federal policy to increase PSH placement among Medicaid enrollees experiencing homelessness.

Economic Analysis of Mandated Protocolized Sepsis Care in New York Hospitals.

OBJECTIVES: Initial evidence suggests that state-level regulatory mandates for sepsis quality improvement are associated with decreased sepsis mortality. However, sepsis mandates require financial investments on the part of hospitals and may lead to increased spending. We evaluated the effects of the 2013 New York State sepsis regulations on the costs of care for patients hospitalized with sepsis. DESIGN: Retrospective cohort study using state discharge data from the U.S. Healthcare Costs and Utilization Project and a comparative interrupted time series analytic approach. Costs were calculated from admission-level charge data using hospital-specific cost-to-charge ratios. SETTING: General, short stay, acute care hospitals in New York, and four control states: Florida, Massachusetts, Maryland, and New Jersey. PATIENTS: All patients hospitalized with sepsis between January 1, 2011, and September 30, 2015. INTERVENTIONS: The 2013 New York mandate that all hospitals develop and implement protocols for sepsis identification and treatment, educate staff, and report performance data to the state. MEASUREMENTS AND MAIN RESULTS: The analysis included 1,026,664 admissions in 520 hospitals. Mean unadjusted costs per hospitalization in New York State were $42,036 ± $60,940 in the pre-regulation period and $39,719 ± $59,063 in the post-regulation period, compared with $34,642 ± $52,403 pre-regulation and $31,414 ± $48,155 post-regulation in control states. In the comparative interrupted time series analysis, the regulations were not associated with a significant difference in risk-adjusted mean cost per hospitalization (p = 0.12) or risk-adjusted mean cost per hospital day (p = 0.44). For example, in the 10th quarter after implementation of the regulations, risk-adjusted mean cost per hospitalization was $3,627 (95% CI, -$681 to $7,934) more than expected in New York State relative to control states. CONCLUSIONS: Mandated protocolized sepsis care was not associated with significant changes in hospital costs in patients hospitalized with sepsis in New York State.

Early impacts of the Pennsylvania Rural Health Model on potentially avoidable utilization.

The Pennsylvania Rural Health Model (PARHM) is a novel alternative payment model for rural hospitals that aims to test whether hospital-based global budgets, coupled with delivery transformation plans, improve the quality of health care and health outcomes in rural communities. Eighteen hospitals joined PARHM in 3 cohorts between 2019 and 2021. This study assessed PARHM's impact on changes in potentially avoidable utilization (PAU)-a measure of admission rates policymakers explicitly targeted for improvement in PARHM. Using a difference-in-differences analysis and all-payer hospital discharge data for Pennsylvania hospitals from 2016 through 2022, we found no significant overall reduction in community-level PAU rates up to 4 years post-PARHM implementation, relative to changes in rural Pennsylvania communities whose hospitals did not join PARHM. However, heterogeneous treatment effects were observed across cohorts that joined PARHM in different years, and between critical access vs prospective payment system hospitals. These findings offer insight into how alternative payment models in rural health care settings may have heterogeneous impacts based on contextual factors and highlight the importance of accounting for these factors in proposed expansions of alternative payment models for rural health systems.

Predictors of viewing progress notes among users of VA's electronic health portal who receive mental health care.

OBJECTIVE: Consistent with the OpenNotes movement, the Veterans Health Administration (VHA) offers patients online access to their clinical notes through the Blue Button feature in its electronic patient health portal, My HealtheVet. We identified demographic, diagnostic, and knowledge-related predictors of viewing clinical notes among veterans receiving VHA mental health care who recently used My HealtheVet. MATERIALS AND METHODS: Three hundred and thirty-eight patients receiving mental health care from 1 VHA medical center who had logged into My HealtheVet in the prior 6 months completed self-report questionnaires assessing their viewing of clinical notes. Additional data were extracted from VHA's Patient Care Database. Multivariable logistic regression was used to examine predictors of viewing notes. RESULTS: Fifty percent of respondents reported having read their notes. In the final multivariable model, post-traumatic stress disorder (PTSD) diagnosis [odds ratio (OR) = 2.30 (1.31-4.07)], speaking with their mental health clinician about their ability to view notes [OR = 3.84 (1.69-8.72)], and being very or extremely confident in understanding the purpose and uses of Blue Button [OR = 9.80 (2.23-43.07) and OR = 13.36 (2.74-65.20), respectively] were associated with viewing notes. DISCUSSION: Patient recall of mental health clinicians speaking to them about their ability to view notes, and confidence in understanding the use and purposes of Blue Button, were stronger predictors of viewing notes than demographic variables. PTSD diagnosis was the only clinical characteristic associated with viewing notes. CONCLUSION: The findings support the value of mental health clinicians openly discussing the availability of notes with patients if they wish to help them take advantage of their potential benefits.
