Effectiveness of medical fee revisions for psychotropic polypharmacy in patients with mood disorders in Japan: An interrupted time-series analysis using a nationwide inpatient database. Asian J Psychiatr 2023; 84:103581. [PMID: 37086613 DOI: 10.1016/j.ajp.2023.103581] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/10/2023] [Revised: 03/30/2023] [Accepted: 04/05/2023] [Indexed: 04/24/2023]
Abstract
BACKGROUND This study aimed to evaluate the effects of medical fee revisions aimed to reduce psychotropic polypharmacy in Japan on the proportion of psychotropic polypharmacy in discharge prescriptions for patients with major depressive disorder (MDD) or bipolar disorder (BD) using a nationwide inpatient database. METHODS In this retrospective cohort study, we used the Diagnosis Procedure Combination database to identify patients with MDD or BD discharged between April 2012 and March 2021. We targeted medical fee revisions in October 2014, April 2016, and April 2018. The major outcome was the monthly proportion of psychotropic polypharmacy in prescription at discharge using the criteria following the April 2018 revision (antidepressants ≥3, antipsychotics ≥3, anxiolytics ≥3, hypnotics ≥3, or sum of anxiolytics and hypnotics ≥4). We performed interrupted time series analyses to evaluate the changes in level and trend between pre- and post-revisions. RESULTS We identified 63,289 and 33,780 patients with MDD and BD respectively in the entire study period. In both the patient groups, there were significant decreases in the proportion of psychotropic polypharmacy at revision in October 2014, and no significant trend and level change at revision were observed in April 2016 and April 2018, with a few exceptions. CONCLUSIONS The medical fee revisions aimed to reduce psychotropic polypharmacy in Japan might have had a limited impact on discharge prescriptions for patients with MDD and BD.

Abstract
BACKGROUND Drug insurance schemes are systems that provide access to medicines on a prepaid basis and could potentially improve access to essential medicines and reduce out-of-pocket payments for vulnerable populations. OBJECTIVES To assess the effects on drug use, drug expenditure, healthcare utilisation and healthcare outcomes of alternative policies for regulating drug insurance schemes. SEARCH METHODS We searched CENTRAL, MEDLINE, Embase, nine other databases, and two trials registers between November 2014 and September 2020, including a citation search for included studies on 15 September 2021 using Web of Science. We screened reference lists of all the relevant reports that we retrieved and reports from the Background section. Authors of relevant papers, relevant organisations, and discussion lists were contacted to identify additional studies, including unpublished and ongoing studies. SELECTION CRITERIA We planned to include randomised trials, non-randomised trials, interrupted time-series studies (including controlled ITS [CITS] and repeated measures [RM] studies), and controlled before-after (CBA) studies. Two review authors independently assessed the search results and reference lists of relevant reports, retrieved the full text of potentially relevant references and independently applied the inclusion criteria to those studies. We resolved disagreements by discussion, and when necessary by including a third review author. We excluded studies of the following pharmaceutical policies covered in other Cochrane Reviews: those that determined how decisions were made about which conditions or drugs were covered; those that placed restrictions on reimbursement for drugs that were covered; and those that regulated out-of-pocket payments for drugs. DATA COLLECTION AND ANALYSIS Two review authors independently extracted data from the included studies and assessed risk of bias for each study, with disagreements being resolved by consensus. We used the criteria suggested by Cochrane Effective Practice and Organisation of Care (EPOC) to assess the risk of bias of included studies. For randomised trials, non-randomised trials and controlled before-after studies, we planned to report relative effects. For dichotomous outcomes, we reported the risk ratio (RR) when possible and adjusted for baseline differences in the outcome measures. For interrupted time series and controlled interrupted time-series studies, we computed changes along two dimensions: change in level; and change in slope. We undertook a structured synthesis following the EPOC guidance on this topic, describing the range of effects found in the studies for each category of outcomes. MAIN RESULTS We identified 58 studies that met the inclusion criteria (25 interrupted time-series studies and 33 controlled before-after studies). Most of the studies (54) assessed a single policy implemented in the United States (US) healthcare system: Medicare Part D. The other four assessed other drug insurance schemes from Canada and the US, but only one of them provided analysable data for inclusion in the quantitative synthesis. The introduction of drug insurance schemes may increase prescription drug use (low-certainty evidence). On the other hand, Medicare Part D may decrease drug expenditure measured as both out-of-pocket spending and total drug spending (low-certainty evidence). Regarding healthcare utilisation, drug insurance policies (such as Medicare Part D) may lead to a small increase in visits to the emergency department. However, it is uncertain whether this type of policy increases or decreases hospital admissions or outpatient visits by beneficiaries of the scheme because the certainty of the evidence was very low. Likewise, it is uncertain if the policy increases or reduces health outcomes such as mortality because the certainty of the evidence was very low. AUTHORS' CONCLUSIONS The introduction of drug insurance schemes such as Medicare Part D in the US health system may increase prescription drug use and may decrease out-of-pocket payments by the beneficiaries of the scheme and total drug expenditures. It may also lead to a small increase in visits to the emergency department by the beneficiaries of the policy. Its effects on other healthcare utilisation outcomes and on health outcomes are uncertain because of the very low certainty of the evidence. The applicability of this evidence to settings outside US healthcare is limited.

Abstract
PURPOSE Because of toxicities, benzodiazepines are not usually recommended in older adults. We therefore sought to describe the trends in benzodiazepine use in long-term care and examine the variation in benzodiazepine use among nursing homes. METHODS In this retrospective repeated cross-sectional analysis of Medicare Parts A, B, and D claims data linked to the Minimum Data Set from 2013 to 2018, we included long-term residents who stayed in a nursing home for at least one entire quarter of a calendar year in 2013-2018. The outcome was whether residents were prescribed a benzodiazepine drug for at least 30 days during each quarter stay. We use mixed effects logistic regression models to assess the variation in benzodiazepine use among nursing homes, adjusting for patient and nursing home characteristics. RESULTS The cohort for the time trend analysis included 270,566 unique residents and 1,843,580 quarter stays for 2013-2018. Prescribing rates for short-acting benzodiazepines were stable over 2013-2016, then declined from 12.1% in 2016 to 10.6% in 2018. The rate of long-acting benzodiazepine use remained relatively steady at around 4% over 2013-2018. During 2017-2018, the variation among nursing homes in benzodiazepine use was 7.2% for short-acting vs. 9.3% for long-acting benzodiazepines, after controlling for resident characteristics. CONCLUSION Prescribing for short-acting benzodiazepines in long-term care declined after 2016, while long-acting benzodiazepine use did not change. The variation in benzodiazepine use among nursing homes is substantial. Identifying factors that explain this variation may help in developing strategies for deprescribing benzodiazepines in nursing home residents.

Abstract
OBJECTIVE Benzodiazepines were excluded from Medicare Part D coverage since its introduction in 2006. Part D expanded coverage for benzodiazepines in 2013. The objective was to examine the impact of Medicare Part D coverage expansion on the utilisation and financial burden of benzodiazepines in older adults. DESIGN Interrupted time series with a control group. SETTING Nationally representative sample. PARTICIPANTS 53 150 468 users of benzodiazepines and 21 749 749 users of non-benzodiazepines (an alternative therapy) from the Medicare Current Beneficiary Survey between the pre-expansion (2006-2012) and post-expansion (2013-2017) periods. INTERVENTION Medicare Part D coverage expansion on benzodiazepines. PRIMARY AND SECONDARY OUTCOME MEASURES Annual rate of benzodiazepines and non-benzodiazepines, average number of benzodiazepines and non-benzodiazepines and average cost of benzodiazepines and non-benzodiazepines. RESULTS After Medicare Part D coverage expansion, the level of the annual rate of benzodiazepines increased by 8.20% (95% CI: 6.07% to 10.32%) and the trend decreased by 1.03% each year (95% CI: -1.77% to -0.29%). The trend of the annual rate of non-benzodiazepines decreased by 0.72% each year (95% CI: -1.11% to -0.33%). For the average number of benzodiazepines, the level increased by 0.67 (95% CI: 0.52 to 0.82) and the trend decreased by 0.10 each year (95% CI: -0.15 to -0.05). For the average number of non-benzodiazepines, the level decreased by 0.11 (95% CI: -0.21 to -0.01) and the trend decreased by 0.04 each year (95% CI: -0.08 to -0.01). No significant level and trend changes were identified for the average cost of benzodiazepines and non-benzodiazepines. CONCLUSIONS After Medicare Part D coverage expansion, there was a sudden increase in the utilisation of benzodiazepines and a decreasing trend in the long-term. The increase in the utilisation of benzodiazepines did not add a financial burden to older adults. As an alternative therapy, the utilisation of non-benzodiazepines decreased following the coverage expansion.

Quantifying cumulative anticholinergic and sedative drug load among US Medicare Beneficiaries. Pharmacoepidemiol Drug Saf 2020; 30:144-156. [PMID: 33000867 DOI: 10.1002/pds.5144] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/25/2020] [Revised: 09/16/2020] [Accepted: 09/22/2020] [Indexed: 12/15/2022]
Abstract
PURPOSE Medications with anticholinergic and sedative properties are widely used among older adults despite strong evidence of harm. The drug burden index (DBI), a pharmacological screening tool, measures these properties across drug classes, and higher DBI drug exposure (DBI > 1) has been associated with certain physical function-related adverse events. Our aim was to quantify mean daily DBI drug exposure among older adults in the United States (US). METHODS We screened medications for DBI properties and operationalized the DBI for US Medicare claims. We then conducted a retrospective cohort study of a 20% random, nationwide sample of 4 137 384 fee-for-service Medicare beneficiaries aged 66+ years (134 757 039 person-months) from January 2013 to December 2016. We measured the monthly distribution based on mean daily DBI, categorized as (a) >0 vs 0 (any use) and (b) 0, 0 < DBI ≤ 1, 1 < DBI ≤ 2, and DBI > 2, and examined temporal trends. We described patient-level factors (eg, demographics, healthcare use) associated with high (>2) vs low (0 < DBI≤1) DBI drug exposure. RESULTS The distribution of the mean daily DBI, aggregated at the month-level, was: 58.1% DBI = 0, 29.0% 0 < DBI≤1, 9.3% 1 < DBI≤2, and 3.7% DBI > 2. Predictors of high monthly DBI drug exposure (DBI > 2) included certain indicators of increased healthcare use (eg, high number of drug claims), white race, younger age, frailty, and a psychosis diagnosis code. CONCLUSIONS The predictors of high DBI drug exposure can inform discussions between patients and providers about medication appropriateness and potential de-prescribing. Future Medicare-based studies should assess the association between the DBI and adverse events.

Abstract
BACKGROUND/OBJECTIVES To describe the use and deprescribing of benzodiazepine receptor agonists (BZRAs) among nursing home residents (NHRs), to evaluate appropriateness of use and to identify factors associated with BZRA use and deprescribing. DESIGN Posthoc analysis of the Collaborative Approach to Optimize Medication Use for Older People in Nursing Homes (COME-ON) study, a cluster controlled trial that evaluated the impact of a complex intervention on potentially inappropriate prescriptions (PIPs) in nursing homes (NHs). SETTING A total of 54 NHs in Belgium. PARTICIPANTS A total of 797 NHRs included in the study who had complete medical, clinical, and medication information at baseline and at the end of the study (month 15). MEASUREMENTS Data were recorded by participating healthcare professionals. Reasons why BZRA use was considered as PIPs were assessed using the 2019 American Geriatrics Society Beers Criteria® and the Screening Tool of Older Persons' Prescriptions (STOPP) criteria, version 2. Deprescribing included complete cessation or decreased daily dose. We identified factors at the NHR, prescriber, and NH levels associated with BZRA use and BZRA deprescribing using multivariable binary and multinomial logistic regression, respectively. RESULTS At baseline, 418 (52.4%) NHRs were taking a BZRA. The use of BZRA for longer than 4 weeks, with two or more other central nervous system active drugs, and in patients with delirium, cognitive impairment, falls, or fractures was found in more than 67% of BZRA users. Eight NHR-related variables and two prescriber-related variables were associated with regular BZRA use. Deprescribing occurred in 28.1% of BZRA users (32.9% in the intervention group and 22.1% in the control group). In addition to four other factors, dementia (odds ratio [OR] = 2.35; 95% confidence interval [CI] = [1.45-3.83]) and intervention group (OR = 1.74; 95% CI = 1.07-2.87) were associated with deprescribing. CONCLUSION Use of BZRAs was highly prevalent, and reasons to consider it as PIP were frequent. Deprescribing occurred in one-fourth of NHRs, which is encouraging. Future interventions should focus on specific aspects of PIPs (ie, indication, duration, drug-drug and drug-disease interactions) as well as on nondementia patients.

Abstract
AbstractPurpose:Adjustment disorder with anxiety (AjD-A) is a common cause of severe anxiety symptoms, but little is known about its prevalence in old age.Methods:This cross-sectional study examined the prevalence of AjD-A in outpatients over the age of 60 who consecutively consulted 34 general practitioners and 22 psychiatrists during a 2-week period. The diagnosis of AjD-A was obtained using the optional module for diagnostic of adjustment disorder of the Mini International Neuropsychiatric Interview (MINI). The study procedure also explored comorbid psychiatric conditions and documented recent past stressful life events, as well as social disability and current pharmacological and non-pharmacological management.Results:Overall, 3651 consecutive subjects were screened (2937 in primary care and 714 in mental health care). The prevalence rate of AjD-A was 3.7% (n = 136). Up to 39% (n = 53) of AjD-A subjects had a comorbid psychiatric condition, mostly of the anxious type. The most frequently stressful life event reported to be associated with the onset of AjD-A was personal illness or health problem (29%). More than 50% of the AjD-A patients were markedly to extremely disabled by their symptoms. Compared to patients who consulted psychiatrists, patients who were seen by primary care physicians were older, had obtained lower scores at the Hamilton Anxiety Rating Scale, benefited less frequently from non-pharmacological management and received benzodiazepines more frequently.Conclusions:AjD-A appears to be a significantly disabling cause of anxiety symptoms in community dwelling elderly persons, in particular those presenting personal health related problems. Improvement of early diagnosis and non-pharmacological management of AjD-A would contribute to limit risks of benzodiazepine overuse, particularly in primary care settings.

Abstract
IMPORTANCE Benzodiazepines, which are associated with safety-related harms for older adults, were not covered when the US Medicare Part D prescription drug benefit began. Coverage was extended to benzodiazepines in 2013. OBJECTIVE To examine whether the expansion of benzodiazepine coverage among Medicare Advantage (MA) beneficiaries was associated with increases in fall-related injuries or overdoses among older adults. DESIGN, SETTING, AND PARTICIPANTS This ecological study used interrupted time-series with comparison-series analyses of MA claims data from 4 635 312 age-eligible MA beneficiaries and 940 629 commercially insured individuals (comparison group) stratified by age (65-69, 70-74, 75-79, and ≥80 years) to separately compare trends in fall-related injury and overdose before (January 1, 2010, to December 31, 2012) and after (January 1, 2013, to December 31, 2015) coverage expansion for benzodiazepines. Data analysis was performed from September 1, 2018, to August 31, 2019. EXPOSURES Expansion of benzodiazepine coverage in Medicare Part D in 2013. MAIN OUTCOMES AND MEASURES Monthly rate of fall-related injury and overdose. RESULTS In 2012 (the year before the policy change), women constituted 57.5% of the MA group and 47.4% of the comparison group. A total of 25.8% of individuals in the MA group were aged 65 to 69 years, and 29.3% were 80 years or older (mean [SD], 75.1 [6.4] years); 56.7% of individuals in the comparison group were aged 65 to 69 years, and 15.1% were 80 years or older (mean [SD] age, 70.9 [6.5] years). In the MA group, 4 635 312 individuals contributed 156 754 749 person-months from 2010 through 2015; in the comparison group, 940 629 individuals contributed 25 104 534 person-months. After coverage of benzodiazepines began, the rate (ie, slope) of fall-related injury among MA beneficiaries increased from before to after coverage among all age groups. Compared with the comparison group, the increase in rate was statistically significant for those 80 years or older (rate changes for the MA vs comparison groups: 0.12 [95% CI, 0.07 to 0.17] vs -0.01 [95% CI, -0.11 to 0.10]; P = .04 for interaction). The overdose trend changed from decreasing to increasing among MA beneficiaries after coverage for all age groups, with a statistically significant increase compared with the comparison group among those aged 65 to 69 years (rate changes for the MA vs comparison groups: 0.23 [95% CI, 0.17 to 0.30] vs 0.02 [95% CI, -0.06 to 0.11]; P < .001 for interaction) and among those 80 years or older (rate changes for the MA vs comparison groups: 0.07 [95% CI, 0.00 to 0.14] vs -0.20 [95% CI, -0.35 to -0.05]; P = .002 for interaction). Results among MA beneficiaries were consistent when stratified by sex and when limited to those prescribed opioids. CONCLUSIONS AND RELEVANCE Medicare's expansion of benzodiazepine coverage may have been associated with increases in the rates of overdose among adults ages 65 to 69 years and in the rates of overdose and fall-related injury among those 80 years or older.

[PMID: 30553910 PMCID: PMC6359959 DOI: 10.1016/j.drugalcdep.2018.11.015] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/20/2018] [Revised: 11/10/2018] [Accepted: 11/13/2018] [Indexed: 12/31/2022]
Abstract
BACKGROUND Benzodiazepine overdose rates have increased in the US, largely from concomitant use of other drugs such as opioids. Studies are needed to examine trends in prescription tranquilizer (e.g., benzodiazepine) use-with a particular focus on use of other drugs such as opioids-to continue to inform prevention efforts. METHODS We conducted a secondary analysis of the 2005-2014 National Survey on Drug Use and Health, a repeated cross-sectional, nationally representative probability sample. Trends in past-year nonmedical tranquilizer use and trends in demographic and other past-year substance use characteristics among nonmedical users were examined (N = 560,099). RESULTS Prevalence of nonmedical tranquilizer use remained stable from 2005/06 through 2013/14 at 2%. Prevalence of past-year heroin use and heroin use disorder both more than doubled among nonmedical tranquilizer users between 2005/06 and 2013/14 (Ps<.001). Nonmedical opioid use decreased between 2005/06 and 2013/14 (P < .001); however, opioid use disorder increased from 13.4% to 16.7% (P = .019). Prevalence doubled among those age >50 between 2005/06 and 2013/14 from 7.9% to 16.5% (P < .001), and nonmedical tranquilizer use among racial minorities also increased (Ps<.01). Prevalence of nonmedical use also increased among those with health insurance (P = .031), and this increase appeared to be driven by a 190.6% increase in nonmedical use among those with Medicare (from 2.6% to 7.4%; P = .002). CONCLUSIONS Characteristics of nonmedical tranquilizer users are shifting, and many shifts are related to past-year nonmedical prescription opioid use and heroin use. Prevention needs to be geared in particular towards older individuals and to those who use opioids nonmedically.

Deprescribing Benzodiazepines in Older Patients: Impact of Interventions Targeting Physicians, Pharmacists, and Patients. Drugs Aging 2018; 35:493-521. [PMID: 29705831 DOI: 10.1007/s40266-018-0544-4] [Citation(s) in RCA: 59] [Impact Index Per Article: 9.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 12/14/2022]
Abstract
Benzodiazepines (BZDs; including the related Z-drugs) are frequently targets for deprescribing; long-term use in older people is harmful and often not beneficial. BZDs can result in significant harms, including falls, fractures, cognitive impairment, car crashes and a significant financial and legal burden to society. Deprescribing BZDs is problematic due to a complex interaction of drug, patient, physician and systematic barriers, including concern about a potentially distressing but rarely fatal withdrawal syndrome. Multiple studies have trialled interventions to deprescribe BZDs in older people and are discussed in this narrative review. Reported success rates of deprescribing BZD interventions range between 27 and 80%, and this variability can be attributed to heterogeneity of methodological approaches and limited generalisability to cognitively impaired patients. Interventions targeting the patient and/or carer include raising awareness (direct-to-consumer education, minimal interventions, and 'one-off' geriatrician counselling) and resourcing the patient (gradual dose reduction [GDR] with or without cognitive behavioural therapy, teaching relaxation techniques, and sleep hygiene). These are effective if the patient is motivated to cease and is not significantly cognitively impaired. Interventions targeted to physicians include prescribing interventions by audit, algorithm or medication review, and providing supervised GDR in combination with medication substitution. Pharmacists have less frequently been the targets for studies, but have key roles in several multifaceted interventions. Interventions are evaluated according to the Behaviour Change Wheel. Research supports trialling a stepwise approach in the cognitively intact older person, but having a low threshold to use less-consultative methods in patients with dementia. Several resources are available to support deprescribing of BZDs in clinical practice, including online protocols.

Abstract
AIMS This study assessed the cost-effectiveness of the orexin receptor antagonist suvorexant against zolpidem, the most widely used hypnotic benzodiazepine receptor agonist in Japan. To this end, a model was used that factored in insomnia and the risk for hip fractures, which have devastating effects on the elderly. METHODS Data were derived from published papers. The target population was a virtual cohort of elderly patients (≥65 years) with insomnia residing in Japan. Cost-effectiveness was evaluated using quality-adjusted life years (QALYs) and the incremental cost-effectiveness ratio as effectiveness measures. The investigators assumed the perspective of healthcare payers. RESULTS In the base-case analysis, suvorexant was cost-saving (suvorexant: $252.3, zolpidem: $328.7) and had higher QALYs gained (suvorexant: 0.0641, zolpidem: 0.0635) for elderly Japanese patients with insomnia compared with zolpidem, indicating that suvorexant was dominant. In the sensitivity analysis, the outcome changed from dominant to dominated due to the relative risk for hip fractures associated with suvorexant. However, when the other parameters were varied from the lower to the upper limits of their ranges, suvorexant remained dominant compared to zolpidem. LIMITATIONS The relative risk for hip fractures for suvorexant used in the model was based on data from pre-approval clinical trials. More precise data may be needed. CONCLUSIONS Suvorexant seemed to be more cost-effective than the alternative zolpidem. The findings suggested that suvorexant might be a viable alternative to zolpidem for elderly patients with insomnia. A sensitivity analysis showed that outcome varied depending on the relative risk for hip fractures associated with suvorexant. Further investigations may be needed for more precise results.

Abstract
OBJECTIVE To describe how use of antidepressants, benzodiazepines, and other anxiolytic/sedative-hypnotics among older adults (age ≥ 65 years) has changed over time among visits to primary care providers and psychiatrists. METHODS Data were from the National Ambulatory Medical Care Survey (years 2003-2005 and 2010-2012), a nationally representative cross-section of outpatient physician visits. Analysis focused on visits to primary care providers (n = 14,282) and psychiatrists (n = 1,095) at which an antidepressant, benzodiazepine, or other anxiolytic/sedative-hypnotic was prescribed, which were stratified by demographic and clinical characteristic (including ICD-9-CM diagnosis) and compared across study intervals. Odds of medication use were calculated for each stratum, adjusting for demographic and clinical characteristics. RESULTS The visit rate by older adults to primary care providers where any of the medications were prescribed rose from 16.4% to 21.8% (adjusted odds ratio [AOR] = 1.43, P < .001) while remaining steady among psychiatrists (75.4% vs 68.5%; AOR = 0.69, P = .11). Primary care visits rose for antidepressants (9.9% to 12.3%; AOR = 1.28, P = .01) and other anxiolytic/sedative-hypnotics (3.4% to 4.7%; AOR = 1.39, P = .01), but the largest growth was among benzodiazepines (5.6% to 8.7%; AOR = 1.62, P < .001). Among patients in primary care, increases primarily occurred among men, non-Hispanic white patients, and those with pain diagnoses as well as those with no mental health or pain diagnoses. CONCLUSIONS From 2003 to 2012, use of the most common psychotropic medications among older adults seen in primary care increased, with concentration among patients with no mental health or pain diagnosis. As the population of older adults grows and receives mental health treatment in primary care, it is critical to examine the appropriateness of psychotropic use.

Abstract
OBJECTIVE To update a past systematic review on whether Medicare Part D changed drug utilization and out-of-pocket (OOP) costs overall and within subpopulations, and to identify evidence gaps. DATA SOURCES/STUDY SETTING Published and gray literature from 2010 to 2015 meeting prespecified screening criteria, including having a comparison group, and utilization or OOP cost outcomes. STUDY DESIGN We conducted a systematic literature review with a quality assessment. DATA COLLECTION/EXTRACTION METHODS For each study, we extracted information on study design, data sources, analytic methods, outcomes, and limitations. Because outcome measures vary across studies, we did a qualitative synthesis rather than meta-analysis. PRINCIPAL FINDINGS Sixty-five studies met screening criteria. Overall, Medicare Part D enrollees have increased drug utilization and decreased OOP costs, but coverage gaps limit the program's impact. Beneficiaries whose insurance becomes more generous after enrollment had disproportionately increased drug utilization and decreased OOP costs. Outcomes among dual-eligibles were mixed. CONCLUSIONS There is strong evidence on how Medicare Part D and the donut hole coverage gap affect utilization and OOP costs, but weak evidence on how effects vary among dual-eligibles or across diseases. Findings suggest that the Affordable Care Act's provisions to expand coverage and reduce the donut hole should improve patient outcomes.

Abstract
OBJECTIVE Frequents cases (10-30% of the elderly population) of regular long-term use of anxiolytic and hypnotic drugs, in particular, benzodiazepines, without control of the physician is an urgent problem of medicine worldwide. Severe and irreversible cognitive impairment is a frequent and severe consequence of this use. Authors studied cognitive impairment in these cases. MATERIAL AND METHODS Patients were enrolled in the study from a psychiatric hospital. The study included 56 women, aged over 50 years, admitted to the hospital with the diagnosis of a mental disorder. Before admission, the patients regularly used benzodiazepines without a prescription for more than 2 months. Later on, anxiolytics were withdrawn during 1-5 days. The patients were studied during 4 weeks in the hospital. To assess the severity and dynamics of their condition, authors used MADRS, HAM-A, MMSE. RESULTS AND CONCLUSION Severe cognitive impairment, achieving the level of dementia, was found in 57.2% of the patients, mild or moderate of cognitive impairment was in 32.1% and only 10.7% had normal level of cognitive functioning. After 4 weeks of benzodiazepine withdrawal, the percentage of patients with dementia reduced to 21.4%, the severity of cognitive impairment was estimated as mild or moderate. A number of patients without cognitive impairment increased to 37.5%. The old age of patients was a significant negative predictor of the dynamics. An impact of the high anxiolytic dose was shown on trend level. The duration of a mental disorder and duration of uncontrollable consumption of anxiolytics and hypnotics did not exert an effect on the development and reversibility of cognitive impairment. A combination of anxiolytics with alcohol increased the risk of dementia and did not reverse the cognitive pathology.

Feasibility of discontinuing chronic benzodiazepine use in nursing home residents: a pilot study. Eur J Clin Pharmacol 2014; 70:1251-60.

Abstract
PURPOSE Guidelines discourage chronic benzodiazepines and related Z drugs (BZD/Zs) for sleep problems. However, prevalence among nursing home residents remains high. Discontinuing these drugs is widely recommended but seems difficult to implement. The aim of our study was to evaluate the overall feasibility in the nursing home, in terms of willingness towards discontinuation and success rate at 8 months, together with the impact on withdrawal symptoms, change in sleep quality, quality of life and medication use. METHODS In a convenience sample of five nursing homes (823 residents), we included cognitively competent residents with chronic BZD/Z use for insomnia. We investigated sleep quality [with Pittsburgh Sleep Quality Index (PSQI)], quality of life (EQ-5D) and withdrawal symptoms [Benzodiazepine Withdrawal Symptom Questionnaire (BWSQ)]. Success rate was analysed with survival analysis. RESULTS Of the 135 eligible residents, both general physician (GP) and resident were willing to initiate discontinuation in 38 residents. Reasons for refusing to initiate discontinuation among GPs was the unmotivated patient and among residents the reluctance towards change. At 8 months, 66.0% were successful discontinuers, with the subjective PSQI component evolving favourably (p = 0.013) and a decreasing number of midnight awakenings (p = 0.041). In the relapse group (n = 13), the quality of life decreased (p = 0.012), with mainly an increase of problems with activities and pain/discomfort. In both groups, the withdrawal symptoms, functionality and medication use did not change. CONCLUSION Discontinuation of chronic BZD/Z use is feasible in the nursing home setting without noticeable withdrawal symptoms, without a switch in medication use, without detrimental effect on quality of life and with a positive effect on the self-perceived sleep quality.
