Closed-loop automated drug infusion regulator: A clinically translatable, closed-loop drug delivery system for personalized drug dosing.

BACKGROUND: Dosing of chemotherapies is often calculated according to the weight and/or height of the patient or equations derived from these, such as body surface area (BSA). Such calculations fail to capture intra- and interindividual pharmacokinetic variation, which can lead to order of magnitude variations in systemic chemotherapy levels and thus under- or overdosing of patients. METHODS: We designed and developed a closed-loop drug delivery system that can dynamically adjust its infusion rate to the patient to reach and maintain the drug's target concentration, regardless of a patient's pharmacokinetics (PK). FINDINGS: We demonstrate that closed-loop automated drug infusion regulator (CLAUDIA) can control the concentration of 5-fluorouracil (5-FU) in rabbits according to a range of concentration-time profiles (which could be useful in chronomodulated chemotherapy) and over a range of PK conditions that mimic the PK variability observed clinically. In one set of experiments, BSA-based dosing resulted in a concentration 7 times above the target range, while CLAUDIA keeps the concentration of 5-FU in or near the targeted range. Further, we demonstrate that CLAUDIA is cost effective compared to BSA-based dosing. CONCLUSIONS: We anticipate that CLAUDIA could be rapidly translated to the clinic to enable physicians to control the plasma concentration of chemotherapy in their patients.

Parent-Led Cognitive Behavioral Teletherapy for Anxiety in Autistic Youth: A Randomized Trial Comparing Two Levels of Therapist Support.

Parent-led cognitive behavioral therapy (CBT) is an efficient, promising form of therapy that may be well suited for autistic youth with anxiety disorders, though to date it has been minimally tested. In this study, 87 autistic youth (7 to 13 years old) with anxiety disorders and their parents were randomized to two forms of parent-led CBT in which parents led their child through a guided CBT workbook across 12 weeks: one with low therapist contact (four 30-minute telehealth calls), and one with standard therapist contact (ten 60-minute telehealth calls). Anxiety, functional impairment, and autism features significantly declined across therapy, without differences between groups. High satisfaction was reported in both groups, though significantly higher satisfaction ratings were reported in standard-contact CBT. Responder rates were 69% of completers at posttreatment (70% in standard contact, 68% in low contact) and 86% at 3-month follow-up (86% in standard contact, 87% in low contact). Low-contact CBT was estimated to incur an average cost of $755.70 per family compared with $1,978.34 in standard-contact CBT. Parent-led CBT with minimal or standard therapist contact both appear to be effective CBT delivery formats for autistic youth with anxiety disorders, with significant cost savings for low-contact CBT.

'More stressful than cancer': Treatment Experiences Lived During Hurricane Maria among Breast and Colorectal Cancer Patients in Puerto Rico.

Background: This study explored experiences in cancer care and disruption after Hurricanes Irma and Maria's aftermath in Puerto Rico (PR). Methods: A total of three focus groups were conducted among breast and colorectal cancer patients diagnosed six months before the disaster. Results: The most prevalent themes were (a) barriers related to their cancer treatment, (b) facilitators related to their cancer treatment, and (c) treatment experiences during the hurricane. Participants discussed struggles regarding their experience with treatment and access to care during and after Hurricanes Irma and Maria and how household limitations due to lack of electricity and water deter their intention to continue their treatment. Moreover, stressors directly linked with the disaster were the most challenging to cope with. Conclusions: Our study identifies the hardships experienced by cancer patients living during a disaster. Similarly, our study highlights the impending need to address in future emergency plans the individual and system needs of cancer patients in active treatment to minimize the delay in continuing cancer care.

Economic Analyses of Obsessive-Compulsive Disorder Interventions: A Systematic Review.

BACKGROUND: Obsessive-compulsive disorder (OCD) is a neuropsychiatric condition featuring patterns of obsessions, compulsions, and avoidant behaviors that are often time consuming and distressing to affected individuals. Cognitive-behavioral therapy (CBT) with exposure and response prevention and/or serotonin reuptake inhibitors are first-line treatments for OCD, though other therapeutic interventions may serve as economically practical modalities under various circumstances. Exploring and understanding the cost effectiveness of all indicated OCD interventions are important to inform therapeutic decisions and provide quality patient-centered care at a cost that is not burdensome to the patient and/or healthcare system. METHODS: A systematic literature review was performed and studies were extracted from PubMed, Embase, Ovid MEDLINE, and Cochrane. All cost-effectiveness studies that included economic analyses with respect to OCD treatment modalities and were written in English and published between January 2010 and July 2022 were eligible for inclusion in the present study. We report a narrative synthesis of the findings and quality appraisal of the selected references. RESULTS: Of the 707 references returned in the literature search, a total of 18 cost-effectiveness studies were included for review. Compared with treatment as usual, several studies reported clinical superiority and cost effectiveness of Internet-based CBT programs for adults and children with OCD at various willingness-to-pay thresholds and economic reference indicators, though cost effectiveness relative to in-person CBT with exposure and response prevention is unclear and estimates of efficacy are likely lower for Internet-based CBT. One study favored the cost utility of serotonin reuptake inhibitor monotherapy over CBT with exposure and response prevention although efficacy estimates of the former tend to be lower, and relative cost differences were low. Five studies evaluated the cost effectiveness of high-intensity neuroaugmentation, including deep brain stimulation and stereotactic radiosurgical capsulotomy, in the context of treatment-refractory OCD. CONCLUSIONS: Despite the relatively high prevalence of OCD worldwide, cost-effectiveness data for therapeutic modalities remain sparse. Because of the chronic nature of OCD, the cost of treatment accumulates and may lead to a significant financial burden over time, particularly when non-evidence-based interventions are used. However, several alternative therapeutic modalities hold promise for economic practicality without significant sacrifice in clinical efficacy. Future studies are necessary to directly compare the cost effectiveness of such therapeutic alternatives with the current standard of care, CBT with exposure and response prevention.

Stepped-Care Cognitive Behavioral Therapy in Children on the Autism Spectrum with Co-occurring Anxiety.

This trial examined stepped-care cognitive-behavioral treatment (CBT) among 96 autistic youth with co-occurring anxiety. Step 1 included an open trial of parent-led, therapist-guided bibliotherapy. Step 2 was family-based CBT for those who did not respond to Step 1 or maintenance for those who did. Eighteen participants (28%) who completed Step 1 responded. Responders reported significantly lower pre-treatment anxiety, internalizing symptoms, and functional impairment than non-responders. After Steps 1 and 2, 80% of completers (55% intent-to-treat) were responders. Anxiety, impairment, and ASD-related impairments significantly improved. Youth in maintenance experienced faster improvement through post-treatment, though there were no group differences at 3-month-follow-up. A stepped approach may help some individuals in Step 1, particularly those who are less anxious.

Years of life lost associated with COVID-19 deaths in the USA during the first 2 years of the pandemic.

BACKGROUND: Prior estimates of the years of life lost (YLLs) in the USA associated with coronavirus disease 2019 (COVID-19) were 1.2 million through 11 July 2020 and 3.9 million through 31 January 2021 (which roughly coincides with the first full year of the pandemic). The aim of this study is to update YLL estimates through the first 2 years of the pandemic. METHODS: We employed data regarding COVID-19 deaths through 5 February 2022 by jurisdiction, gender and age group. We used actuarial life expectancy tables by gender and age to estimate YLLs. RESULTS: We estimated roughly 9.7 million YLLs due to COVID-19 deaths. The number of YLLs per 10 000 capita was 297.5, with the highest rate in Mississippi (482.7) and the lowest in Vermont (61.4). There was substantial interstate variation in the timing of YLLs and differences in YLLs by gender. YLLs per death increased from 9.2 in the first year of the pandemic to 10.8 through the first 2 years. CONCLUSIONS: Our findings improve our understanding of how the mortality effects of COVID-19 have evolved. This insight can be valuable to public health officials as the disease moves to an endemic phase.

The relationship between abortion rates and economic fluctuations.

We analyze the relationship between abortions and economic fluctuation at the U.S. state level for the 1995-2016 period. We do not find a statistically significant association between the overall abortion rate and the unemployment rate across the full sample period. However, we observe a procyclical association from approximately 2004 to 2010, during which a one percentage point increase in the unemployment rate is associated with a roughly 5% decrease in the abortion rate. This procyclical association is confirmed when we subsample our data to the 2005-2016 period. Our subgroup analysis indicates a procyclical association for the abortion rates for younger women, while we do not observe statistically significant associations when the analysis is stratified by race or ethnicity. The associations we observe for the younger age groups are especially pronounced in states with restrictions on Medicaid funding of abortions. Our analysis suggests that economic conditions may be an important factor in the reproductive choices by women.

Stepped Care Versus Standard Care for Children After Trauma: A Randomized Non-Inferiority Clinical Trial.

OBJECTIVE: Trauma-focused cognitive-behavioral therapy (TF-CBT) is an evidence-based therapist-led treatment for children after trauma. Parents often experience barriers to treatment engagement, including cost. Stepped care TF-CBT (SC-TF-CBT) was developed as an alternative delivery system. Step One is a parent-led therapist-assisted treatment. Step Two provides therapist-led TF-CBT for children who did not benefit from Step One and require more intensive treatment. This study compared SC-TF-CBT to standard TF-CBT in a community-based non-inferiority trial. METHOD: A total of 183 children (aged 4-12 years) experiencing posttraumatic stress symptoms (PTSS) and their caregivers were randomly assigned to SC-TF-CBT or standard TF-CBT within 6 community clinics. Assessments occurred at baseline, mid- and posttreatment, and 6 and 12 months. Primary outcomes included PTSS and impairment. Secondary outcomes included severity, diagnostic status, remission, and response. Treatment cost, acceptability, and satisfaction were measured. Difference and non-inferiority tests were applied. RESULTS: SC-TF-CBT participants changed at rates comparable to participants in TF-CBT for primary and secondary measures. SC-TF-CBT was non-inferior to TF-CBT for PTSS, impairment, and severity at all time points except for impairment at the 6-month assessment. Attrition did not differ between treatment arms (132 participants were completers). Baseline treatment acceptability was lower for SC-TF-CBT parents, although there was no difference in expected treatment improvements or treatment satisfaction at posttreatment. Based on regression estimates, total costs were 38.4% lower for SC-TF-CBT compared to TF-CBT, whereas recurring costs were 53.7% lower. CONCLUSION: Stepped Care TF-CBT provides an alternative way to deliver treatment for some children and parents, with reduced cost for providers and parents.

Intervention cost-effectiveness for pediatric anxiety and OCD: A systematic review and integrated database model.

BACKGROUND: While multiple treatments for pediatric anxiety and obsessive compulsive disorder (OCD) are efficacious, little is known about their cost-effectiveness. In response, we sought to provide relevant information through systematic review and cost-effectiveness simulation. METHODS: We evaluated the cost-effectiveness of treatment for pediatric anxiety and OCD in two ways. First, we conducted a systematic review following PRISMA guidelines. Second, we evaluated cost-effectiveness for antidepressant medication, cognitive behavioral therapy, and their combination via a simulation that integrated information from the Truven MarketScan database and the NIMH National Database for Clinical Trials Related to Mental Illness. RESULTS: Both systematic review and simulation found antidepressant medication and cognitive behavioral therapy to be cost-effective for pediatric anxiety and OCD. Antidepressant medication was the least costly approach, and cognitive behavioral therapy provided additional cost-effectiveness, especially for OCD. LIMITATIONS: During systematic review, relatively few articles provided information about both costs and effectiveness. While there was a notable margin of error to support multiple interventions as cost-effective, limited prior research decreased precision of point estimates and comparisons between interventions. CONCLUSIONS: Both antidepressant medication and cognitive behavioral therapy were found to be cost-effective for pediatric anxiety and OCD. Results supported investment from third party payers, who serve as critical gatekeepers that can increase treatment dissemination. However, more precise information would better inform the exact amount of investment needed, especially with regard to selection decisions between active interventions. Cost-effectiveness research would benefit from systematic collection of data on treatment costs and quality of life in future clinical trials.

Years of life lost associated with COVID-19 deaths in the USA during the first year of the pandemic.

BACKGROUND: Years of Life Lost (YLLs) measure the shortfall in life expectancy due to a medical condition and have been used in multiple contexts. Previously it was estimated that there were 1.2 million YLLs associated with coronavirus disease 2019 (COVID-19) deaths in the USA through 11 July 2020. The aim of this study is to update YLL estimates for the first full year of the pandemic. METHODS: We employed data regarding COVID-19 deaths in the USA through 31 January 2021 by jurisdiction, gender and age group. We used actuarial life expectancy tables by gender and age to estimate YLLs. RESULTS: We estimated roughly 3.9 million YLLs due to COVID-19 deaths, which correspond to roughly 9.2 YLLs per death. We observed a large range across states in YLLs per 10 000 capita, with New York City at 298 and Vermont at 12. Nationally, the YLLs per 10 000 capita were greater for males than females (136.3 versus 102.3), but there was significant variation in the differences across states. CONCLUSIONS: Our estimates provide further insight into the mortality effects of COVID-19. The observed differences across states and genders demonstrate the need for disaggregated analyses of the pandemic's effects.

Economic Evaluation of Dupilumab Versus Endoscopic Sinus Surgery for the Treatment of Chronic Rhinosinusitis With Nasal Polyps.

BACKGROUND: Dupilumab is a novel monoclonal antibody that recently received US Food and Drug Administration approval for the treatment of chronic rhinosinusitis with nasal polyps. Endoscopic sinus surgery (ESS) has been the mainstay of treatment for patients refractory to initial medical therapy. Data comparing the cost-effectiveness of these treatments are scarce. The objective of this study is to compare the cost-effectiveness of dupilumab and ESS treatment for patients with chronic rhinosinusitis with nasal polyps refractory to medical therapy. METHODS: A cohort-style Markov decision tree economic evaluation with 10-year time horizon was performed. The two comparative treatment strategies were dupilumab therapy or ESS followed by postoperative maintenance therapy. Patients with response to treatment continued with either maintenance or dupilumab therapy; patients with no response underwent ESS. The primary outcome measure was incremental cost per quality-adjusted life-year calculated from Sino-Nasal Outcome Test (SNOT-22) scores. Sensitivity analyses were performed including discounting scenarios and a probabilistic sensitivity analysis. RESULTS: The dupilumab strategy cost $195,164 and produced 1.779 quality-adjusted life-years. The ESS strategy cost $20,549 and produced 1.526 quality-adjusted life-years. This implies an incremental cost of $691,691 for dupilumab for every 1-unit increase in quality-adjusted life-year compared with ESS. Probability sensitivity analysis indicated that ESS was more cost-effective than dupilumab in all iterations. CONCLUSIONS: While dupilumab and ESS may demonstrate similar clinical effectiveness, ESS remains the most cost-effective treatment option and should remain the standard of care for patients with chronic rhinosinusitis with nasal polyps refractory to medical therapy.

Excess Mortality Associated With COVID-19 by Demographic Group: Evidence From Florida and Ohio.

OBJECTIVE: COVID-19 mortality varies across demographic groups at the national level, but little is known about potential differences in COVID-19 mortality across states. The objective of this study was to estimate the number of all-cause excess deaths associated with COVID-19 in Florida and Ohio overall and by sex, age, and race. METHODS: We calculated the number of weekly and cumulative excess deaths among adults aged ≥20 from March 15 through December 5, 2020, in Florida and Ohio as the observed number of deaths less the expected number of deaths, adjusted for population, secular trends, and seasonality. We based our estimates on death certificate data from the previous 10 years. RESULTS: The results were based on ratios of observed-to-expected deaths. The ratios were 1.17 (95% prediction interval, 1.14-1.21) in Florida and 1.15 (95% prediction interval, 1.11-1.19) in Ohio. Although the largest number of excess deaths occurred in the oldest age groups, in both states the ratios of observed-to-expected deaths were highest among adults aged 20-49 (1.21; 95% prediction interval, 1.11-1.32). The ratio of observed-to-expected deaths for the Black population was especially elevated in Florida. CONCLUSIONS: Although excess deaths were largely concentrated among older cohorts, the high ratios of observed-to-expected deaths among younger age groups indicate widespread effects of COVID-19. The high levels of observed-to-expected deaths among Black adults may reflect in part disparities in infection rates, preexisting conditions, and access to care. The finding of high excess deaths among Black adults deserves further attention.

An evaluation of the Veterans Health Administration National Nursing Education Initiative.

BACKGROUND: Since 1999, the Veterans Health Administration's (VHA) National Nursing Education Initiative (NNEI) has provided 16,294 scholarships for registered nurses to attain baccalaureate and advanced nursing degrees. PURPOSE: The goal of this evaluation was to determine factors that enhanced or hindered a scholarship recipient in the completion of their degree and service obligation. METHODS: A regression analysis was performed to identify predictors of degree completion for 10,043 participants in 162 VHA facilities. FINDINGS: Significant predictor variables for degree completion were intended occupation, entry degree, gender, age, and year entering the program. Eighty-six percent (86.7%) of participants completed the degree requirement. Of those who completed their degree, 97% completed the service obligation. DISCUSSION: As recruitment and retention initiative, NNEI scholarships are poised to address the VHA nursing staffing shortages as well as build a highly qualified nursing workforce capable of providing the best care to our Nation's Veterans.

Years of life lost associated with COVID-19 deaths in the United States.

BACKGROUND: The mortality effects of COVID-19 are a critical aspect of the disease's impact. Years of life lost (YLLs) can provide greater insight than the number of deaths by conveying the shortfall in life expectancy and thus the age profile of the decedents. METHODS: We employed data regarding COVID-19 deaths in the USA by jurisdiction, gender and age group for the period 1 February 2020 through 11 July 2020. We used actuarial life expectancy tables by gender and age to estimate YLLs. RESULTS: We estimated roughly 1.2 million YLLs due to COVID-19 deaths. The YLLs for the top six jurisdictions exceeded those for the remaining 43. On a per-capita basis, female YLLs were generally higher than male YLLs throughout the country. CONCLUSIONS: Our estimates offer new insight into the effects of COVID-19. Our findings of heterogenous rates of YLLs by geography and gender highlight variation in the magnitude of the pandemic's effects that may inform effective policy responses.

Potential undercounting of overdose deaths caused by specific drugs in vital statistics data: An analysis of Florida.

INTRODUCTION: Due largely to ambiguous or incomplete information provided on death certificates, the widely cited Multiple Cause of Death (MCOD) data reported by the U.S. Centers for Disease Control and Prevention has been shown to undercount the number of fatal overdoses caused by specific drugs. However, the extent of the undercounts is unclear. METHODS: We obtained the number of fatal overdoses from 2003 to 2017 in Florida caused by the three drug groups (amphetamines, benzodiazepines, and opioids) and three drugs (methadone, cocaine, and heroin) that we could map across the MCOD data and data reported by the Florida Medical Examiners Commission (FMEC). The FMEC data are based on state-mandated reporting of the causal drugs in overdose deaths. We analyzed the differences across all deaths and by gender, age group, and race. RESULTS: Depending on the drug, the numbers of deaths across all individuals reported in the FMEC data ranged from 19 %-39 % higher than the counts in the MCOD data. The differences varied over time and by some demographic factors. CONCLUSIONS: The MCOD data appear to undercount the number of fatal overdoses caused by the drugs we investigated. Our analysis did not identify a cause or pattern to explain the differences. Efforts to improve the reporting of fatal overdoses may enhance our understanding of and subsequently may improve the response to the drug overdose epidemic.

Factors associated with the timing of abortions.

The timing of an abortion (often measured as gestational age) can have important effects on the woman's physical health and on the cost of the procedure. To the authors' knowledge, there has been only one national analysis of the factors associated with the gestational age at abortion, but it employed data from over 20 years ago. The state-specific studies that have explored abortion timing have typically examined the effects of a specific change in abortion regulations. In this study, we employ annual, state-level data covering the 1991-2014 period that measure the frequency of abortions by gestational age. We regress these measures of abortion utilization on policy, economic, demographic, and health care infrastructure characteristics. The estimates indicate that the introduction of state restrictions on Medicaid funding of abortions is associated with a 13% increase in the rate of abortions after the first trimester. We do not find a statistically significant association between parental involvement laws and the rate or percentage of post-first-trimester abortions.

Emergency Department Visits by and Hospitalizations of Senior Diabetics in the Three Years Following Hurricanes Katrina and Rita.

While prior studies have investigated health care utilization immediately following disasters, few have examined utilization beyond that period. We use individual-level U.S. Medicare claims data for three years prior to (2002-2004) and after (2006-2008) Hurricanes Katrina and Rita to investigate whether senior diabetics affected by the storms had a greater number of emergency department visits and days hospitalized in the three years following the storms. An event study was conducted using regression analysis that controlled for all fixed individual characteristics. While the 2006 and 2007 rates of increase in utilization were relatively similar across the control group and the two affected groups, in 2008 the affected groups exhibited substantially greater increases in both emergency department visits and days hospitalized. The differences correspond to an additional 380,907 days hospitalized and 21,583 emergency department visits in 2008. The results indicate that, in addition to short term effects previously estimated, disasters may have longer term effects on utilization of healthcare services. These potential effects suggest that improved post-disaster care may significantly reduce the healthcare costs of disasters.

Long-term Effects of Disasters on Seniors With Diabetes: Evidence From Hurricanes Katrina and Rita.

OBJECTIVE: To estimate the long-run mortality effects of Hurricanes Katrina and Rita on seniors with diabetes. RESEARCH DESIGN AND METHODS: We performed a retrospective cohort analysis of Medicare enrollment and claims data covering four states and ∼10 years. Affected individuals were identified by whether they lived in a county that suffered a high impact and were stratified by whether they moved to a different county following the storms. Propensity scores matched affected and comparison subjects based on demographic and socioeconomic characteristics and the presence of chronic conditions. Our sample consisted of 170,328 matched affected subjects. RESULTS: The affected subjects had a nearly 40% higher all-cause mortality risk in the 1st month after the storms, but the difference fell to <6% by the end of the full observation period. The mortality risks of heart disease and nephritis also exhibited the largest differences immediately following the storms. Among the affected subjects, the all-cause mortality risk was higher for those who moved to a different county, with an especially large difference among those who moved to an affected county. CONCLUSIONS: The propensity matching procedure resulted in the comparison and affected groups having similar observable characteristics. However, we only examined the extreme outcome of mortality, our definition of affected was somewhat crude, and our sample did not include individuals enrolled in Medicare Advantage. Our findings highlight the importance of the immediate response to disasters, yet also demonstrate the long-lasting impact disasters can have.

Cost conscious care: preoperative evaluation by a cardiologist prior to low-risk procedures.

Background: Preoperative testing before low-risk procedures remains overutilised. Few studies have looked at factors leading to increased testing. We hypothesised that consultation to a cardiologist prior to a low-risk procedure leads to increased cardiac testing. Methods and results: 907 consecutive patients who underwent inpatient endoscopy/colonoscopy at a single academic centre were identified. Of those patients, 79 patients (8.7%) received preoperative consultation from a board certified cardiologist. 158 control patients who did not receive consultation from a cardiologist were matched by age and gender. Clinical and financial data were obtained from chart review and hospital billing. Logistic and linear regression models were constructed to compare the groups. Patients evaluated by a cardiologist were more likely to receive preoperative testing than patients who did not undergo evaluation with a cardiologist (OR 47.5, (95% CI 6.49 to 347.65). Specifically, patients seen by a cardiologist received more echocardiograms (60.8% vs 22.2%, p<0.0001) and 12-lead electrocardiograms (98.7% vs 54.4%, p<0.0001). There was a higher rate of ischaemic evaluations in the group evaluated by a cardiologist, but those differences did not achieve statistical significance. Testing led to longer length of stay (4.35 vs 3.46 days, p=0.0032) in the cohort evaluated by a cardiologist driven primarily by delay to procedure of 0.76 days (3.14 vs 2.38 days, p=0.001). Estimated costs resulting from the longer length of stay and increased testing was $10 624 per patient. There were zero major adverse cardiac events in either group. Conclusion: Preoperative consultation to a cardiologist before a low-risk procedure is associated with more preoperative testing. This preoperative testing increases length of stay and cost without affecting outcomes.

Long-term Effects of Disasters on Health Care Utilization: Hurricane Katrina and Older Individuals with Diabetes.

OBJECTIVE: While the short-term effects of disasters on health care utilization are well documented, less is known regarding potential longer-term effects. This study investigates the effects of Hurricane Katrina on the health care utilization of older individuals with diabetes. METHODS: We examined Medicare claims and enrollment data for the 2002-2004 and 2006-2008 time periods for older individuals with diabetes. Our quasi-experimental design analyzed utilization across 2 treated and 3 control groups. We compared the proportion of individuals who received a screen related to diabetes before and after Katrina in the treated groups to the proportions in the control groups. Our regression analysis employs individual and year fixed effects to control for factors specific to a given individual or to a given year. RESULTS: We found that utilization rates in the 2002-2004 period exhibited roughly parallel trends for the treated and control groups, which provides support for our research design. The 2006-2008 utilization rates were generally lower for the treated groups than they were for the control groups. The differences were especially pronounced for older age cohorts. CONCLUSIONS: Our study suggests that the effects of disasters on health care utilization may persist for years after the event. Recovery efforts may be improved by addressing both short-term and long-term health care interruptions. (Disaster Med Public Health Preparedness. 2019;13:724-731).
