RESUMO
AIMS: Among people with diabetes using insulin, severe hypoglycaemia (SH) can be a life-threatening complication, if untreated. The personal experiences during an SH event from the perspectives of people with diabetes and their caregivers are not well-characterized. This study assessed the perceptions of the event and the decision making processes of people with diabetes (T1D n = 36; T2D n = 24) and their caregivers during SH events. METHODS: In-depth one-on-one telephone interviews were conducted with dyads of people with diabetes and caregivers in the United States (n = 120). An initial synopsis and inductive codebook schema were used to analyse the data with two independent coders (kappa = 0.87-0.89). Themes were developed from the codes, and codes were re-mapped to the themes. RESULTS: Four themes were formed: (1) Caregivers scramble to do the right thing and support people with diabetes in treating SH; (2) Decision making capacity is impaired during an SH event, often a panicked time; (3) People learn to manage SH events through their own experiences and frequently make lifestyle changes to prevent and treat future events; and (4) Discussion with healthcare providers about SH, and particularly SH treatment, is limited. CONCLUSIONS: SH events are stressful and often evoke emotional reactions that can impair decision making. Thus, advance treatment planning of SH events needs to occur. Much of the knowledge about SH treatment derives from prior experience rather than healthcare provider guidance, suggesting a need for healthcare providers to initiate proactive discussions about SH treatment.

OBJECTIVE: Sepsis is a leading cause of mortality in noncoronary ICUs. Although immediate start of antibiotics reduces sepsis-related mortality, antibiotics are often administered for too long, leading to suboptimal treatment and, importantly, contributes to antimicrobial resistance. Prior literature suggests that procalcitonin correlates with infection and thus may help to guide the decision on when to stop antibiotic treatment. This study was conducted as part of a regulatory submission to the U.S. Food and Drug Administration and aimed to summarize the evidence of procalcitonin guidance on efficacy and safety outcomes in adult patients with sepsis. DATA SOURCES: PubMed and the Cochrane Database of Systematic Reviews. STUDY SELECTION: English-language randomized controlled trials evaluating procalcitonin use among adult patients with suspected or confirmed sepsis published between January 2004 and May 2016. DATA EXTRACTION: Inverse-variance weighting fixed and random effects meta-analyses were performed on the following efficacy and safety endpoints: antibiotic duration, all-cause mortality, and length of ICU stay. Two reviewers independently extracted data elements from identified studies and measured risk of bias with the Cochrane Risk of Bias Tool. DATA SYNTHESIS: From a total of 369 potentially eligible articles, 10 randomized controlled trials containing 3,489 patients were used for analysis. Procalcitonin-guided patients had shorter antibiotics duration compared with controls (7.35 vs. 8.85 d; weighted mean difference, -1.49 d; 95% CI, -2.27 to -0.71; p < 0.001). Procalcitonin use had no adverse impact on mortality (risk ratio, 0.90; 95% CI, 0.79-1.03; p = 0.114) and length of ICU stay (11.09 d vs. 11.91 d; weighted mean difference, -0.84 d; 95% CI, -2.52 to 0.84; p = 0.329). CONCLUSIONS: In adult patients with suspected or confirmed sepsis, procalcitonin guidance reduces antibiotics duration with no observed adverse effects on patient outcomes.

Although effective for bacterial lower respiratory tract infections (LRTIs), antibiotic treatment is often incorrectly prescribed for non-bacterial LRTIs. Procalcitonin has emerged as a promising biomarker to diagnose bacterial infections and guide antibiotic treatment decisions. As part of a regulatory submission to the U.S. Food and Drug Administration, this systematic review and meta-analysis summarizes the effects of procalcitonin-guided antibiotic stewardship on antibiotic use and clinical outcomes in adult LRTI patients. PubMed and the Cochrane Database of Systematic Reviews were searched for English-language randomized controlled trials published between January 2004 and May 2016. Random and fixed effects meta-analyses were performed to study efficacy (initiation of antibiotics, antibiotic use) and safety (mortality, length of hospital stay). Eleven trials were retained, comprising 4090 patients. Procalcitonin-guided patients had lower odds of antibiotic initiation (odds ratio: 0.26; 95% confidence interval [CI]: 0.13-0.52) and shorter mean antibiotic use (weighted mean difference: -2.15 days; 95% CI: -3.30 to -0.99) compared to patients treated with standard care. Procalcitonin use had no adverse impact on mortality (relative risk: 0.94; 95% CI: 0.69-1.28) and length of hospital stay (weighted mean difference: -0.15 days; 95% CI: -0.60 to 0.30). Procalcitonin guidance reduces antibiotic initiation and use among adults with LRTIs with no apparent adverse impact on length of hospital stay or mortality.

BACKGROUND: It is not known if there is a differential impact on Alzheimer's disease (AD) diagnosis and outcomes if/when patients are diagnosed with cognitive decline by specialists versus non-specialists. This study examined the cost trajectories of Medicare beneficiaries initially diagnosed by specialists compared to similar patients who received their diagnosis in primary care settings. METHODS: Patients with ≥2 claims for AD were selected from de-identified administrative claims data for US Medicare beneficiaries (5 % random sample). The earliest observed diagnosis of cognitive decline served as the index date. Patients were required to have continuous Medicare coverage for ≥12 months pre-index (baseline) and ≥12 months following the first AD diagnosis, allowing for up to 3 years from index to AD diagnosis. Time from index date to AD diagnosis was compared between those diagnosed by specialists (i.e., neurologist, psychiatrist, or geriatrician) versus non-specialists using Kaplan-Meier analyses with log-rank tests. Patient demographics, Charlson Comorbidity Index (CCI) during baseline, and annual all-cause medical costs (reimbursed by Medicare) in baseline and follow-up periods were compared across propensity-score matched cohorts. RESULTS: Patients first diagnosed with cognitive decline by specialists (n = 2593) were younger (78.8 versus 80.8 years old), more likely to be male (40 % versus 34 %), and had higher CCI scores and higher medical costs at baseline than those diagnosed by non-specialists (n = 13,961). However, patients diagnosed by specialists had a significantly shorter time to AD diagnosis, both before and after matching (mean [after matching]: 3.5 versus 4.6 months, p < 0.0001). In addition, patients diagnosed by specialists had significantly lower average total all-cause medical costs in the first 12 months after their index date, a finding that persisted after matching ($19,824 versus $25,863, p < 0.0001). Total per-patient annual medical costs were similar for the two groups starting in the second year post-index. CONCLUSIONS: Before and after matching, patients diagnosed by a specialist had a shorter time to AD diagnosis and incurred lower costs in the year following the initial cognitive decline diagnosis. Differences in costs converged during subsequent years. This suggests that seeking care from specialists may yield more timely diagnosis, appropriate care and reduced costs among those with cognitive decline.

OBJECTIVES: Estimate the prevalence and healthcare costs of undiagnosed opioid abuse among commercially insured individuals. STUDY DESIGN: Retrospective analysis of de-identified pharmacy and medical claims data and publicly-available survey data (no IRB approval required). METHODS: This study focused on commercially insured individuals. Rates of prescription pain-reliever abuse/dependence ("abuse") among individuals ages ≥12 were calculated using National Survey on Drug Use and Health (NSDUH) public-use data for 2006-2011 and assumed to capture both diagnosed and undiagnosed opioid abuse. Rates of undiagnosed opioid abuse were calculated as the difference between NSDUH rates and published rates of diagnosed opioid abuse. OptumHealth Reporting and Insights claims data were used to estimate the healthcare costs of undiagnosed abuse. Diagnosed abusers ages 12-64 were identified using ICD-9-CM diagnosis codes for opioid abuse/dependence. Pre-diagnosis costs were assumed to be a proxy for undiagnosed opioid abuse costs. The ratio of undiagnosed to diagnosed abuse costs was calculated as the ratio of annual per-patient healthcare costs between pre-diagnosis and post-diagnosis periods. RESULTS: While rates of diagnosed opioid abuse among commercially insured individuals increased from 0.07% in 2006 to 0.19% in 2011, rates of undiagnosed abuse decreased from 0.42% to 0.38% over the same time period. Annual per-patient healthcare costs of undiagnosed abusers were 69.2% of those of diagnosed abusers. CONCLUSIONS: Per-patient healthcare costs of undiagnosed abusers among the commercially insured are estimated to be lower than those of diagnosed abusers. However, the higher prevalence of undiagnosed opioid abuse implies that undiagnosed abuse represents a substantial burden to commercial payers.

INTRODUCTION: Recent developments in diagnostic technology can support earlier, more accurate diagnosis of non-Alzheimer's disease (AD) dementias. METHODS: To evaluate potential economic benefits of early rule-out of AD, annual medical resource use and costs for Medicare beneficiaries potentially misdiagnosed with AD prior to their diagnosis of vascular dementia (VD) or Parkinson's disease (PD) were compared with that of similar patients never diagnosed with AD. RESULTS: Patients with prior AD diagnosis used substantially more medical services every year until their VD/PD diagnosis, resulting in incremental annual medical costs of approximately $9,500-$14,000. However, following their corrected diagnosis, medical costs converged with those of patients never diagnosed with AD. DISCUSSION: The observed correlation between timing of correct diagnosis and subsequent reversal in excess costs is strongly suggestive of the role of misdiagnosis of AD - rather than AD comorbidity - in this patient population. Our findings suggest potential benefits from earlier, accurate diagnosis.

OBJECTIVE: The objective of this study was to examine the effect of treatment timing on risk of institutionalization of Medicaid patients with Alzheimer's disease (AD) and to estimate the economic implications of earlier diagnosis and treatment initiation. METHODS: New Jersey Medicaid claims data (1997-2009) were used retrospectively to study the effect of treatment on time to institutionalization. Observed Medicaid payments were used to calculate savings from delayed institutionalization, adjusting for cost offsets resulting from concurrent changes in use of other medical services. RESULTS: Initiation of existing therapies at earliest symptomatic onset is predicted to delay institutionalization by 91 days, reducing Medicaid costs by $19,108/institutionalized patient. Incorporating an 18.5% cost offset from increased use of other medical services as well as drug costs associated with earlier treatment results in net savings of $12,687/patient. Projected annual Medicaid savings exceed $1 billion. CONCLUSION: Earlier treatment leads to a small delay in institutionalization among AD patients, resulting in significant costs savings to Medicaid.

BACKGROUND AND OBJECTIVES: Piflufolastat F 18 is a novel prostate-specific membrane antigen (PSMA)-targeted positron emission tomography (PET) radiotracer that is superior to standard of care (SOC) imaging for the initial staging of prostate cancer and the detection of biochemical recurrence. As piflufolastat F 18 has been approved in the United States (US) for this indication, this modeling study assessed the cost effectiveness of piflufolastat F 18 versus fluciclovine F-18, gallium68-PSMA-11 (PSMA 11), and SOC imaging (a mix of bone scans, computed tomography, and magnetic resonance imaging) for the diagnosis and staging of prostate cancer from a US healthcare system perspective. PERSPECTIVE: A US third-party payer perspective was used, which for this population reflects a mix of commercial and Medicare, considering only direct healthcare costs. SETTING: This study utilized a tertiary healthcare setting. METHODS: A decision tree was used to map the diagnostic/treatment pathway, consisting of the proportion of patients with local, regional, distant, or no disease; prostate-specific antigen (PSA) ≤ 1.0 or > 1.0; and accuracy of imaging modalities. A Markov model predicted the long-term outcomes of disease progression according to treatment decisions. Inputs to the model were informed by data from the OSPREY and CONDOR clinical trials, public data, and the literature. Treatment mix included active surveillance, radiation therapy, prostatectomy, androgen deprivation therapy (ADT), and radiation therapy + ADT, informed by expert opinion. Outcomes included life-years (LY), quality-adjusted life-years (QALY), and the incremental cost-effectiveness ratio (ICER). All costs were reported in 2021 US dollars, using the US Bureau of Labor Statistics Consumer Price Index. A willingness-to-pay (WTP) threshold of $150,000 was considered cost effective, consistent with the upper range used as the standard for price benchmarks by the Institute for Clinical and Economic Review. The robustness of the base-case results was assessed in deterministic and probabilistic sensitivity analyses. RESULTS: Over a lifetime horizon, piflufolastat F 18 had the greatest effectiveness in terms of LYs (6.80) and QALYs (5.33); for the comparators, LYs ranged from 6.58 (SOC) to 6.76 (PSMA 11) and QALYs ranged from 5.12 (SOC) and 5.30 (PSMA 11). Piflufolastat F 18 was more cost effective compared with fluciclovine F 18, PSMA 11, and SOC, with ICERs of $21,122, $55,836, and $124,330 per QALY gained, respectively. Piflufolastat F 18 was associated with the greatest net monetary benefit ($627,918) compared with the other options at a WTP threshold of $150,000. The results of the deterministic and probabilistic sensitivity analyses supported the robustness of the base-case results. CONCLUSIONS: This study suggests that piflufolastat F 18 is a cost-effective diagnostic option for men with prostate cancer in the US, with higher associated LY, QALY, and greater net monetary benefit than fluciclovine F 18, PSMA 11, and SOC imaging.

To assess the clinical impact of delayed testosterone recovery (TR) following the discontinuation of medical androgen deprivation therapy (ADT), a retrospective, longitudinal analysis was conducted in adult males with prostate cancer using the Optum® de-identified Electronic Health Record data set and Optum® Enriched Oncology Data (2010-2021). Of 3875 patients who initiated and discontinued ADT, 1553 received one or more testosterone-level tests within the 12 mo following discontinuation and were included in this study. These 1553 patients were categorized into two cohorts: 25% as TR (testosterone levels >280 ng/dl at any test within 12 mo following ADT discontinuation) and 75% as non-TR. At baseline, non-TR patients were older, had lower testosterone levels, and were more likely to have diabetes, hyperlipidemia, and hypertension, but less likely to have sexual dysfunction. After adjustment for baseline characteristics, the TR cohort had a lower risk of new-onset diabetes (hazard ratio [HR] 0.47; 95% confidence interval [CI] 0.27-0.79), trended toward a lower risk of new-onset depression (HR 0.58; 95% CI 0.33-1.02), and had a higher likelihood of seeking treatment for sexual dysfunction (HR 1.33; 95% CI 0.99-1.78) versus the non-TR cohort. These findings support monitoring testosterone levels after ADT discontinuation to manage potential long-term comorbidities in patients with prostate cancer. Patient summary: This real-world analysis of males with prostate cancer who were treated with medical androgen deprivation therapy (ADT) found that most patients did not have their testosterone level checked in the 12 mo after stopping ADT. Of those who did, 75% did not achieve normal testosterone levels (>280 ng/dl), and these patients were more likely to experience new-onset diabetes than those who achieved normal testosterone levels. These results suggest that to ensure effective clinical decision-making, physicians should check patients' testosterone levels after stopping ADT.
RESUMO
Aim: Estimate the cost-per-remitter with esketamine nasal spray plus an oral antidepressant (ESK + oral AD) versus oral AD plus nasal placebo (oral AD + PBO) among patients with treatment-resistant depression. Patients & methods: An Excel-based model was developed to estimate the cost-per-remitter for ESK + oral AD versus oral AD + PBO over 52 weeks from multiple US payer perspectives. Clinical end points and cost inputs were derived from clinical trials and the literature, respectively. Results: Under the base-case scenario, the cost-per-remitter for ESK + oral AD and oral AD + PBO were as follows: Commercial: US$85,808 versus US$100,198; Medicaid: US$76,236 versus US$96,067; Veteran's Affairs: US$77,765 versus US$104,519; and Integrated Delivery Network: US$103,924 versus US$142,766. Conclusion: The findings suggest that ESK + oral AD is a cost-efficient alternative treatment for treatment-resistant depression compared with oral AD + PBO.
Lay abstract The US FDA recently approved esketamine nasal spray plus an oral antidepressant (AD) as a new treatment for adults with treatment-resistant depression. We developed an Excel-based model to understand whether esketamine + oral AD treatment offers better value for the money spent, compared with treatment with oral AD alone. We find that the higher annual costs of esketamine + oral AD treatment are more than offset by the better clinical outcomes achieved with this treatment. Specifically, in a given year, more people treated with esketamine + oral AD versus oral AD alone achieved and remained in remission, and as a result, they incurred fewer other medical costs.

OBJECTIVE: Large hemispheric infarction (LHI) is associated with a high likelihood of the evolution of life-threatening edema. Few studies have assessed real-world clinical outcomes and management strategies among patients with LHI. The objective of this study was to describe the management, in-hospital outcomes, and direct healthcare resource burden of patients with LHI, as well as those of patients with subsequent cerebral edema. METHODS: This observational, retrospective cohort study analyzed de-identified data from US adult patients using the IBM MarketScan Hospital Drug Database (Q4-2015 to Q4-2017). Patients were included in the "Possible LHI" or the "Other Ischemic Strokes" cohorts using ICD-10 diagnosis codes. Patients with possible LHI were further categorized into "LHI with Edema" and "LHI without Edema" subgroups using diagnosis and procedure codes. Select clinical and economic outcomes were compared between cohorts and subgroups using multivariable regressions. RESULTS: Of 79,201 eligible encounters with ischemic strokes, 11,772 unique patients were assigned to the Possible LHI cohort while 67,429 were assigned to the Other Ischemic Strokes cohort. Among patients with possible LHI, 869 (7%) were assigned to the LHI with Edema subgroup and 10,903 (93%) were assigned to the LHI without Edema subgroup. Patients in the Possible LHI cohort had longer hospital stays (mean difference [MD] [95%CI] = 2.6 [2.4;2.8] days), higher total facility charges (MD [95%CI] = $28,656 [26,794;30,524]), and higher odds of death (odds ratio [95%CI] = 2.2 [2.0;2.4]) than the Other Ischemic Strokes cohort. Among patients with possible LHI, the incremental clinical and resource burden was further exacerbated in the subgroup of patients with edema (hospital days: MD [95%CI] = 5.0 [3.9;6.2] days; total facility charges: MD [95%CI] = $59,585 [50,816;67,583]; mortality: odds ratio [95%CI] = 10.3 [8.5;12.4]). CONCLUSIONS: Among patients with ischemic strokes, LHI was associated with increased clinical management and direct healthcare resource burden in real-world hospital settings. The burden was substantially increased among patients who developed cerebral edema.

INTRODUCTION: Research has shown increased health-care resource use (HRU) among patients with Alzheimer's disease and related disorders (ADRD) well before diagnosis, but the degree to which HRU is correlated with disease severity at the time of initial assessment is not well documented. METHODS: Retrospective analysis of linked medical records and claims data for three cohorts: mild ADRD (first [index] Mini-Mental State Examination [MMSE] ≥20), moderate/severe ADRD (index MMSE < 20), controls without cognitive impairment. HRU during the pre-index year was compared using multivariate regressions. RESULTS: ADRD cohorts had significantly (P < .01) higher HRU than controls. Compared to mild ADRD patients, moderate/severe ADRD patients had higher rates of hospitalizations (relative risk [RR]: 1.57), emergency department visits (RR: 1.36), potentially avoidable hospitalizations (RR: 1.72), and accidental falls (RR: 1.58). DISCUSSION: HRU before initial assessment increases with disease severity at the time of assessment, highlighting the need for timely evaluation and improved management in the earliest stages of ADRD.
RESUMO
OBJECTIVES: Our aim was to describe the incidence of Alzheimer's disease (AD) in the United States, overall and by geographic region. DESIGN: We conducted retrospective analyses of administrative claims data for a 5% random sample of US Medicare beneficiaries aged 65 years or older. AD incidence, defined as a diagnosis for AD (International Classification of Disease, Ninth Revision, Clinical Modification code 331.0×) in a given year, with no AD diagnosis in the beneficiary's entire medical history, was estimated for each calendar year between 2007 and 2014. Beneficiaries were required to be enrolled in Medicare for the calendar year of evaluation as well as the preceding 12 months. In addition, a cross-sectional assessment of geographic variation in AD incidence was conducted for 2014. For each population area (specifically, core-based statistical area, as defined by the US Census Bureau), AD incidence was estimated overall, as well as adjusted for differences in underlying patient demographics and metrics of access to care and quality of care. Changes in AD incidence from 2007 were also estimated. SETTING: US fee-for-service Medicare. PARTICIPANTS: US Medicare beneficiaries aged 65 years or older with no history of AD. RESULTS: Overall, the diagnosed incidence of AD decreased over time, from 1.53% in 2007 to 1.09% in 2014; trends were similar for most population areas. In 2014, the rates of AD incidence ranged from 0% to more than 3% across population areas, with the highest observed incidence rates in areas of the Midwest and the South. Statistical models explain little of the geographic variation, although following adjustment, the incidence rates increased the most (in relative terms) in rural areas of western states. CONCLUSION: Our findings are consistent with previously reported estimates of incidence of AD in the United States and its recent declining trend. Additionally, the study highlights the considerable geographic variation in the incidence of AD in the United States and suggests that further research is needed to better understand the determinants of this geographic variation.

INTRODUCTION: This study evaluates rates of all-cause emergency department visits, all-cause hospitalizations, potentially avoidable hospitalizations, and falls in 3 years preceding Alzheimer's disease (AD) diagnosis. METHODS: Patients with AD and controls with no cognitive impairment were identified from the Medicare claims data. Patients were required to be aged ≥ 65 years and have continuous Medicare enrollment for ≥4 years before the index date (AD cohort: first AD diagnosis in 2012-2014; controls: randomly selected medical claim). Outcomes for each preindex year were compared among propensity score-matched cohorts. RESULTS: Each year, before index, patients with AD were more likely to have all-cause emergency department visits, all-cause hospitalizations, potentially avoidable hospitalizations, and falls (P < .05 for all comparisons) than matched controls (N = 19,679 pairs). Increasing absolute and relative risks over time were observed for all outcomes. DISCUSSION: The study findings highlight the growing burden of illness before AD diagnosis and emphasize the need for timely recognition and management of patients with AD.
RESUMO
INTRODUCTION: This study estimated the minimal clinically important difference (MCID) for Mini Mental State Examination, Clinical Dementia Rating Scale sum of boxes, and Functional Activities Questionnaire across the Alzheimer's disease (AD) spectrum. METHODS: Retrospective analysis of the National Alzheimer's Coordinating Center Uniform Data Set (9/2005-9/2016) and MCID for clinical outcomes were estimated using anchor-based (clinician's assessment of meaningful decline) and distribution-based (1/2 baseline standard deviation) approaches, stratified by severity of cognitive impairment. RESULTS: On average, a 1-3 point decrease in Mini Mental State Examination, 1-2 point increase in Clinical Dementia Scale sum of boxes, and 3-5 point increase in Functional Activities Questionnaire were indicative of a meaningful decline. The MCID values generally increased by disease severity; the effect size and standardized response mean for those with meaningful decline were consistently in the acceptable ranges for MCID. DISCUSSION: These findings can inform design and interpretation of future clinical trials.
RESUMO
Purpose: To evaluate the budget impact of adding a diagnostic test of tissue inhibitor of metalloproteinase 2 and insulin-like growth factor binding protein 7 ([TIMP-2]·[IGFBP7]), which identifies patients at risk of moderate-to-severe acute kidney injury (AKI), to the current standard of care (SOC) in a hospital setting.Materials and methods: A budget impact model (2017 USD) was developed from the perspective of a hypothetical US hospital system serving 10,000 inpatients annually. The model estimated the impact of assessing the risk of AKI using SOC vs a combination of SOC and the US Food and Drug Administration-approved assay [TIMP-2]·[IGFBP7] over a 1-year period. Potential cost implications were assessed using estimates for payer mix among patients, diagnostic efficacy, and patient healthcare resource utilization. The model also considered provider adoption rates and the estimated costs of [TIMP-2]·[IGFBP7].Results: Compared to SOC alone, adding [TIMP-2]·[IGFBP7] to SOC was associated with a $1,855 reduction in uncompensated care per patient tested, which, after accounting for the additional costs of the test ($277), resulted in net savings of $1,578 per patient tested. The findings were robust to input parameter variations, as demonstrated by deterministic and probabilistic sensitivity analyses. In the probabilistic sensitivity analyses, net cost savings to the hospital ranged from $50,308-$3,971,514, or $101-$7,943 per tested patient (mean = $1,710; 95% confidence interval = $1,691-$1,729).Conclusions: The introduction of [TIMP-2]·[IGFBP7] as a novel tool in the identification of AKI risk may result in considerable cost savings from a hospital perspective under this model's base-case assumptions. Further prospective studies are needed to confirm these findings in a real-world setting.Key points for decision makersAn economic model was constructed to determine the budget impact of adding a diagnostic test ([TIMP-2]·[IGFBP7]), which identifies patients at risk of moderate-to-severe acute kidney injury, to the current standard of care (SOC) in a hospital setting.According to the present model, the use of [TIMP-2]·[IGFBP7] to identify acute kidney injury risk may reduce costs for hospitals by â¼$1,578 per patient tested.

BACKGROUND: Abuse of prescription opioids [opioid use disorder (OUD), poisoning, and fatal and non-fatal overdose] is a public health and economic challenge that is associated with considerable morbidity and mortality in the USA and globally. OBJECTIVE: To systematically review and summarize the health economics literature published over the last 5 years that describes the economic burden of abuse of prescription opioids. METHODS: Findings from searches of databases including MEDLINE, Embase, and Cochrane CENTRAL as well as hand searches of multiple conference abstracts were screened against predefined inclusion criteria to identify studies reporting cost and healthcare resource utilization (HRU) data associated with abuse of prescription opioids. RESULTS: A total of 49 unique studies were identified. Most of the studies examined direct costs and HRU, which were substantially higher for abusers of prescription opioids than non-abuser controls in several matched cohort analyses (US$20,343-US$28,718 vs US$9716-US$14,079 for mean direct combined annual healthcare costs reported in 6 studies). Although only a small number of studies reported indirect costs, these findings suggest a high societal burden related to productivity losses, absenteeism, morbidity, and mortality among those who abuse opioids. Studies of medication-assisted treatment demonstrated that factors such as adherence, dose, formulation (film or tablet), and relapse during treatment, were associated with direct costs and HRU among treated patients. CONCLUSIONS: This systematic literature review shows that abuse of prescription opioids is characterized by substantial direct healthcare costs, medical utilization, and related societal costs. Future research should further investigate the indirect costs of opioid abuse.
