Association between daily antiretroviral pill burden and treatment adherence, hospitalisation risk, and other healthcare utilisation and costs in a US medicaid population with HIV.

ABSTRACT:

Objectives

Lower pill burden leads to improved antiretroviral therapy (ART) adherence among HIV patients. Simpler dosing regimens have not been widely explored in real-world populations. We retrospectively assessed ART adherence, all-cause hospitalisation risk and costs, and other healthcare utilisation and costs in Medicaid enrollees with HIV treated with ART as a once-daily single-tablet regimen (STR) or two or more pills per day (2+PPD).

Design

Patients with an HIV diagnosis from 2005 to 2009 receiving complete ART (ie, two nucleoside/nucleotide reverse transcriptase inhibitors plus a third agent) for ?60 days as STR or 2+PPD were selected and followed until the first of (1) discontinuation of the complete ART, (2) loss of enrolment or (3) end of database. Adherence was measured using the medication possession ratio. Monthly all-cause healthcare utilisation and costs were observed from regimen initiation until follow-up end.

Results

Of the 7381 patients who met inclusion criteria, 1797 were treated with STR and 5584 with 2+PPD. STR patients were significantly more likely to reach 95% adherence and had fewer hospitalisations than 2+PPD patients (both p<0.01). STR patients had mean (SD) total monthly costs of $2959 ($4962); 2+PPD patients had $3544 ($5811; p<0.001). Hospital costs accounted for 53.8% and pharmacy costs accounted for 32.5% of this difference. Multivariate analyses found that STR led to a 23% reduction in hospitalisations and a 17% reduction in overall healthcare costs. ART adherence appears to be a key mechanism mediating hospitalisation risk, as patients with ?95% adherence (regardless of regimen type) had a lower hospitalisation rate compared with <95% adherence.

Conclusions

While it was expected that STR patients would have lower pharmacy costs, we also found that STR patients had fewer hospitalisations and lower hospital costs than 2+PPD patients, resulting in significantly lower total healthcare costs for STR patients.

Project description:IntroductionDifferences in healthcare utilization and medical expenditures associated with perinatal depression are estimated.MethodsUsing the MarketScan Multi-State Medicaid Database, the analytic cohort included individuals aged 15-44 years who had an inpatient live birth delivery hospitalization between January 1, 2017 and December 31, 2018. Multivariable negative binomial regression models were used to estimate the differences in utilization associated with perinatal depression, and multivariable generalized linear models were used to estimate the differences in expenditures associated with perinatal depression. Analyses were conducted in 2021.ResultsThe cohort included 330,593 individuals. Nearly 17% had perinatal depression. Compared with individuals without perinatal depression individuals with perinatal depression had a larger number of inpatient admissions (0.19, 95% CI=0.18, 0.20), total inpatient days (0.95, 95% CI=0.92, 0.97), outpatient visits (14.02, 95% CI=13.81, 14.22), emergency department visits (1.70, 95% CI=1.66, 1.74), and weeks of drug therapy covered by a prescription (28.70, 95% CI=28.12, 29.28) and larger total expenditures ($5,078, 95% CI=$4,816, $5,340). Non-Hispanic Black individuals had larger differences in utilization and expenditures for inpatient services and outpatient visits but smaller differences in utilization for pharmaceutical services associated with perinatal depression than non-Hispanic White individuals. Hispanic individuals had larger differences in utilization for outpatient visits but smaller differences in utilization for pharmaceutical services associated with perinatal depression than non-Hispanic White individuals.ConclusionsIndividuals with perinatal depression had more healthcare utilization and medical expenditures than individuals without perinatal depression, and differences varied by race/ethnicity. The findings highlight the need to ensure comprehensive and equitable mental health care to address perinatal depression.

Project description:ObjectiveTemporomandibular joint disorder (TMD) requires long-term management and can be a financial burden for patients. Here, we investigated the treatment received by people diagnosed with TMD and its relevant costs.DesignA descriptive, cross-sectional study.Setting and participantsWe performed secondary data analysis of health insurance claims data provided by the Health Insurance Assessment and Review (HIRA) of the Republic of Korea. We reviewed the records of 10 041 patients who were diagnosed with TMD and who utilised outpatient healthcare service at least once between January and December 2017.Primary and secondary outcome measuresData on use of medical services, hospitalisations, sociodemographic factors, treatment and medication were retrieved and analysed. Cost was defined as the cost of care incurred by a health insurance beneficiary at a care facility.ResultsWe reported the characteristics as medians, frequencies and percentages and found that most TMD patients were outpatients, women (58.9%) and in their 20s (46.4%). For visit type, 85.9% of all patients had an outpatient dental medical visit, with most visiting dental clinics and dental hospitals. Western medicine (WM; 9.8%) was prescribed more often, followed by Korean medicine (KM; 8.2%). The median expense per patient was highest among those in their 20s (58.00, 23.90, 53.40, 65.90 US$ for overall, WM, dental medicine (DM) and KM, respectively). Consultation fees accounted for the greatest percentage (42.8%) of DM and WM care expenses, while injection/non-surgical intervention fees accounted for the greatest percentage of KM care expenses. The most commonly used treatments for TMD were temporomandibular joint stimulation therapy (51.1%) and acupuncture (19.9%), considered as the most basic care for TMD. Psychosomatic agents (86.4%) were the most commonly used medications in outpatients.ConclusionsWhile people with TMD most commonly received temporomandibular stimulation therapy, the costs and duration of treatment varied significantly for these patients.
