Aim: Exploring the healthcare costs and resource use among privately insured US patients with post-traumatic stress disorder (PTSD). Methods: This study used Merative MarketScan data. The index date was defined as the first PTSD claim. Study period included a 1-year pre-index and 2-year post-index follow-up. Cases with only acute PTSD, cancer, or insurance gap during the study period were excluded. The PTSD with (PwC) and PTSD without comorbidities (PwoC) cohorts were defined by the presence/absence of comorbid mental health conditions (schizophrenia, bipolar and major depressive disorder). Baseline PTSD (BP) cohort included PwoC cases with only index PTSD event and without FDA-approved PTSD medications or psychotherapy. Sub-analysis is conducted among patients with PTSD and substance/alcohol use disorder. Study cohorts were matched in a 1:1:1 ratio. Results: The matched sample included 5076 patients (1681 PwC, 1681 PwoC, 1714 BP). PwC patients had higher 2-year PTSD-related costs than PwoC and BP patients ($3762 vs $1750 and $841; all p < 0.001). The same trend was noted among all-cause and anxiety-related costs. PwC patients had higher 2-year PTSD-related inpatient and emergency department (ED) rates than PwoC (10.2% vs 1.7% and 6.8% vs 2.6%, all p < 0.001) and inpatient and outpatient rates than BP (10.2% vs 2.1% and 98.0% vs 93.1%; all p ≤ 0.004). The sub-analysis had 3776 patients (3154 PwC, 537 PwoC, 85 BP). PwC had higher 2-year PTSD-related costs than PwoC and BP ($7668 vs $2919 and $1,483; all p < 0.001). The same trend was noted in all-cause and anxiety-related costs. PwC also had higher 2-year PTSD-related inpatient and ED rates than PwoC (25.6% vs 10.4% and 12.7% vs 5.2%; all p < 0.001) and inpatient and outpatient rates than BP (25.6% vs 8.2% and 95.5% vs 84.7%; all p < 0.001). Conclusion: PTSD is associated with high healthcare costs and resource use. The highest economic burden was observed in patients with PTSD and mental health comorbidities.

Objective: This retrospective claims analysis explored the treatment utilization and characteristics among patients with post-traumatic stress disorder (PTSD) of different severity., Methods: The index date was the first PTSD claim. The analysis observed 12 months pre- and 24 months post-index. Adults with insurance gaps, cancer, or acute PTSD during the observation were excluded. Patients were categorized into three severity cohorts based on treatment and healthcare services utilization for PTSD: 1. Baseline PTSD (BP) (no PTSD visits post-index, no FDA-approved medications/ psychotherapy, and no severe mental health comorbidities); 2. PTSD without Comorbidities (PwoC) (≥1 PTSD visits post-index and no severe mental health conditions); 3. PTSD with Comorbidities (PwC) (≥1 PTSD visits post-index and severe mental health comorbidities present). For the primary analysis, cohorts were propensity-score matched. A sub-analysis examined patients with PTSD and Substance or Alcohol Use Disorder (SUD/AUD)., Results: The primary analysis observed 1714 BP, 1681 PwoC, and 1681 PwC patients. Treatment utilization rates were highest among PwC vs. other cohorts (84.5% psychotherapy, 76.1% off-label medications, and 26.1% FDA-approved medications [p<0.001]). PwC cohort also had the highest number of psychotherapy sessions and medication prescriptions per patient (20.1 sessions, 12.6 off-label prescriptions, and 2.0 FDA-approved prescriptions [p<0.001]). The proportion of days covered (PDC) indicated low medication adherence (0.25-0.40) with adherent patient rates (PDC ≥0.80) between 8.0-17.5%. The SUD/AUD sub-analysis identified 85 BP, 537 PwoC, and 3154 PwC patients. Conclusions were similar, with PwC cohort having highest treatment utilization rates (87.1% psychotherapy, 85.0% off-label medications, 28.2% FDA-approved medications [p≤0.013] with 24.4 sessions, 16.1 off-label prescriptions, and 2.0 FDA-approved prescriptions per patient [p≤0.002]). Only 4.7-11.4% of patients were adherent., Conclusions: PwC patients received psychotherapy and pharmacotherapy more frequently than PwoC and BP patients. Medication adherence among treated patients was low. Patients with SUD/AUD had numerically higher treatment utilization and lower medication adherence., Competing Interests: The authors have read the journal’s policy and have the following competing interests: FS, VZ, and DG are employees of ZRx Outcomes Research Inc., which received funding from Lykos for this work.

Background: No curative therapy is available for Parkinson's disease; therefore, one of the main goals of treatment is to control motor symptoms, often via the use of levodopa (also known as L-dopa). However, prolonged levodopa treatment in Parkinson's disease has been associated with the development of motor fluctuations and the occurrence of levodopa-induced dyskinesias (LIDs)., Objective: To gain a clear, empirical understanding of the current real-world approach to treatment and patient outcomes associated with Parkinson's disease and LIDs., Methods: This study used a mixed methodology, combining a cross-sectional survey of neurologists practicing in the United States, a retrospective chart review of patients with Parkinson's disease and LIDs, and cross-sectional surveys of health-related quality of life (QOL) and physical functioning in patients with Parkinson's disease. The surveys included the 39-item Parkinson's Disease Questionnaire, the Unified Parkinson's Disease Rating Scale, the Parkinson Disease Dyskinesia 26-item Scale, and the modified Abnormal Involuntary Movement Scale (mAIMS). Survey and chart data were collected between May 2010 and July 2011. Descriptive analyses were used to evaluate the distribution of study variables, treatment patterns, patient QOL, and patient physical functioning., Results: Data from 7 neurologists and from 172 patients with Parkinson's disease and LIDs were collected. Results from the physician survey indicate that prescribing patterns depend largely on the severity of LIDs, assessed via mAIMS. Most patients (88%) received pharmacologic therapy as first-line treatment for LIDs, with monotherapy favored in patients with mild LIDs and combination therapy in patients with moderate-to-severe LIDs. The mean time from the diagnosis of LID to the administration of first-line treatment for the condition was 10.7 months (standard deviation, 14.0 months). The study population reflects a mean time from levodopa initiation to the onset of LIDs of slightly more than 5 years, regardless of the levodopa dosage. Results from the chart review and the physician survey suggest a strong alignment in severity classification among the assessment scales used., Conclusion: These findings indicate that the diagnosis and the treatment of Parkinson's disease and LIDs are not optimal, because of the length of time from diagnosis to treatment, and because of the variability in treatment selection and response. Additional real-world studies are recommended to better understand treatment patterns, compliance with guidelines, and their potential impact on patient outcomes.
