Association between psychotropic drug use and prescription opioid use among older adults.

This study investigated the association between psychotropic drug use and prescription opioid use/high dosage opioid use among older adults. A sample of 203,750 older adults enrolled in Pennsylvania's Pharmaceutical Assistance Contract for the Elderly (PACE) program during 2017 was evaluated for prescription opioid and psychotropic drug usage. High dosage opioid use was defined as using >90 morphine milligram equivalents (MME)/day for ≥90 consecutive days. Overall, 20.7% of enrollees filled opioid prescriptions, of which 1.4% used them at high dosages. Multivariate logistic regression indicated that the odds of prescription opioid use increased with anxiolytic/sedative/hypnotic use and antidepressant use. Moreover, high dosage opioid use was significantly associated with anxiolytic/sedative/hypnotic use, antidepressant use and other factors including being younger, male, white, and married but living separately, and having multiple opioid prescribers. Clinicians should carefully evaluate opioid use among older patients using anxiolytics or antidepressants to minimize risks for adverse consequences of opioids.

The relationship between proton pump inhibitor adherence and fracture risk in the elderly.

Studies suggest that long-term use of proton pump inhibitors (PPIs) may be associated with an increased risk of fracture. However, the role of medication adherence in this association is not fully understood. A retrospective cohort study was conducted to examine the relationship between PPI use/adherence and fracture risk among elderly subjects by combining administrative pharmacy claims data, survey data, and Medicare data. The study cohort included 1,604 PPI users and 23,672 nonusers who were enrolled in Pennsylvania's Pharmaceutical Assistance Contract for the Elderly program. PPI adherence was measured by the proportion of days covered (PDC). Time-dependent Cox proportional hazards models were used to estimate adjusted hazard ratios (HRs) of PPI use/adherence for fracture risk while controlling for demographics, comorbidity, body mass index, smoking, and non-PPI medication use. The overall incidence of any fracture per 100 person-years was 8.7 for PPI users and 5.0 for nonusers. A gradient in fracture risk according to PPI adherence was observed. Relative to nonusers, fracture HRs associated with the highest (PDC ≥ 0.80), intermediate (PDC 0.40-0.79), and lowest (PDC <0.40) adherence levels were 1.46 (p < 0.0001), 1.30 (p = 0.02), and 0.95 (p = 0.75), respectively. In addition, the fracture risk of PPI use was significant for hip (HR = 1.32, p = 0.04) and vertebral (HR = 1.69, p = 0.0005) fractures, and risk was similar between major osteoporotic and other fractures. These results provide further evidence that PPI use may increase fracture risk in the elderly and highlight the need for clinicians to periodically reassess elderly patients' individualized needs for ongoing PPI therapy, while weighing potential risks and benefits.

A Retrospective Study of Psychotropic Drug Use and Prescription Opioid Initiation Among Older Adults.

Individuals with mental health problems may be more vulnerable to using prescription opioids than their counterparts. Therefore, the main objective of this study was to assess the initiation of prescription opioids in older adults who used psychotropic drugs compared with those who did not. The authors used a retrospective cohort design and included a sample of older adults enrolled in Pennsylvania's Pharmaceutical Assistance Contract for the Elderly program who did not use prescription opioids in 2013. Using pharmacy claims, patients who used anxiolytics/sedatives/hypnotics (n = 13,512) or antidepressants (n = 17,492) between October and December 2013 were identified and compared with those who did not use anxiolytics/sedatives/hypnotics (n = 114,091) or antidepressants (n = 110,111) during that period, to determine the incidence of prescription opioid use in 2014. Chi-square tests and multivariate logistic regressions were performed for analyses. Compared with patients who did not use anxiolytics/sedatives/hypnotics, those who used were more likely to initiate prescription opioids (15.0% versus 22.0%, P < .0001). Similarly, compared with patients who did not use antidepressants, those who used were more likely to initiate prescription opioids (14.7% versus 21.9%, P < .0001). Multivariate logistic regression indicated that the odds of prescription opioid initiation increased with anxiolytic/sedative/hypnotic use by 44% (AOR = 1.44; P < .0001) and antidepressant use by 48% (AOR = 1.48; P < .0001) among older adults after adjusting for potential confounding variables. Results showed that prescription opioid initiation is associated with prior anxiolytic/sedative/hypnotic or antidepressant use among older adults. Patients with mental health problems should also be queried about pain experiences for effective treatment.

Association of Medication Adherence with Hospital Utilization and Costs Among Elderly with Diabetes Enrolled in a State Pharmaceutical Assistance Program.

BACKGROUND: Medication adherence is crucial for the successful treatment among elderly patients with diabetes taking oral antidiabetic medications (OAMs). Cost of medications, lack of insurance coverage, and low income are major contributing factors towards medication nonadherence. State pharmaceutical assistance programs (SPAPs) provide medications at little or no cost to income-eligible patients and have potential to improve medication adherence among elderly patients. Despite this, limited research has focused on the association of medication adherence with health care utilization among elderly patients enrolled in SPAPs, and inclusion of health care costs as an outcome is even rarer. OBJECTIVE: To evaluate the relationship between adherence to OAMs and hospital utilization and costs among elderly patients with diabetes who were enrolled in a SPAP. METHODS: This retrospective observational study included elderly patients with diabetes enrolled in Pennsylvania's Pharmaceutical Assistance Contract for the Elderly (PACE) program in 2015. Medication adherence was estimated as the proportion of days covered (PDC; adherent: PDC≥80%, nonadherent: PDC < 80%). Hospital utilization and costs were estimated using hospital discharge records from the Pennsylvania Health Care Cost Containment Council. Multiple adjusted regression analyses were used to examine the association of medication adherence with hospital utilization (all-cause and diabetes-related number of inpatient hospital visits and length of stay [LOS]) and costs. RESULTS: Among 9,497 elderly PACE enrollees with diabetes, 81% were adherent, and 21% were hospitalized. Compared with adherent patients, patients who were nonadherent to OAMs had twice the odds of all-cause and diabetes-related hospitalization. Controlling for covariates, nonadherent patients had 27% more all-cause (95% CI = 9%-36%) and 21% more diabetes-related (95% CI = 5%-40%) hospital visits than adherent patients. Covariate-adjusted LOS for nonadherent patients was 24% longer than that of adherent patients for all-cause hospitalization (95% CI = 1.171-1.311) and 12.7% longer for diabetes-related hospitalization (95% CI = 1.036-1.227). Medication nonadherence was associated with significantly greater all-cause ($22,670 vs. $16,383; P < 0.0001) and diabetes-related ($13,518 vs. $12,634; P = 0.0003) hospitalization costs. CONCLUSIONS: Among SPAP-enrolled elderly patients, nonadherence to OAMs was significantly associated with increased risk of hospitalization, longer hospital stays, and greater hospitalization costs. Attention is needed to improve medication adherence among elderly receiving financial assistance to pay their prescriptions to reduce economic burden on the health care system. DISCLOSURES: No outside funding supported this study. The authors have nothing to disclose.

Can Academic Detailing Move the Needle for Patients with Diabetes in a State-Based Prescription Drug Benefit Program?

BACKGROUND: Publicly funded prescription drug programs, such as state pharmacy assistance programs, provide critical benefits for the care of individuals, but they are frequently limited in their resources to optimize patient outcomes. The application of quality metrics to prescription drug claims may help to determine whether prescribers' adherence to national standards can be augmented through academic detailing. OBJECTIVE: To evaluate changes in diabetes drug prescribing patterns after an academic detailing educational intervention in 2013 and 2014 for prescribers in the Pennsylvania Pharmaceutical Assistance Contract for the Elderly (PACE) program. METHODS: We used a retrospective, quasiexperimental study design that applied interrupted time series and segmented regression analysis, and examined PACE pharmacy claims data for 1 year before and 1 year after the academic detailing intervention. Four diabetes prescribing metrics were evaluated at monthly intervals for a sample of 574 prescribers who received academic detailing and for a propensity score-matched comparison sample of 574 prescribers who did not receive the intervention. RESULTS: The prescribers who received academic detailing did not differ significantly after the intervention from the providers who did not receive the intervention in their prescribing trends for the 4 diabetes metrics. The observed time series patterns suggest that diabetes-related ceiling effects were likely, with relatively small room for improvement at the group level during the study period. CONCLUSION: The results of this study did not demonstrate group differences in prescribing trends that were attributable to the intervention. However, many prescribers in the detailed group had been exposed to similar educational outreach by PACE before 2013, which limits the interpretation of this finding. In addition, the diabetes quality metrics had been the standard of care during the preceding decade, with a broad dissemination of the treatment guidelines to the provider community. These results are consistent with a ceiling effect in the measured metrics, suggesting that most prescribers in both groups were largely following core diabetes guidelines before and after the intervention.

The role of medication use and health on the decision to quit drinking among older adults.

OBJECTIVE: To determine the extent to which changes in medication use and health influence the decision to quit drinking among older adults. METHOD: The sample consisted of 8,883 elderly enrolled in Pennsylvania's Pharmaceutical Assistance Contract for the Elderly (PA-PACE) program who completed surveys in 2000 and 2002. Survey data were linked with prescription claims to examine medication and health factors associated with drinking cessation between baseline and follow-up. RESULTS: Overall, 3.9% of those using alcohol at baseline quit drinking during the study period. Logistic regression results showed that individuals who initiated antipsychotic (OR = 2.92) and antineoplastic therapies (OR = 2.67) were the most likely to quit drinking. DISCUSSION: These findings support the hypothesis that elderly quit drinking in response to ill health. Results have implications for alcohol interventions in older adults and underscore the importance of separating former drinkers from lifetime abstainers in the study of alcohol-health relationships.

Initial Medication Adherence in the Elderly Using PACE Claim Reversals: A Pilot Study.

BACKGROUND: The Medicare Modernization Act, with its requirements for Medicare Part D to comply with electronic prescribing (e-prescribing), bolstered the adoption of e-prescribing, which increased to 73% in 2013. Therefore, understanding whether electronic prescriptions are less likely to be picked up is important as e-prescribing continues to be emphasized. OBJECTIVE: To assess whether prescription origin is among the factors associated with initial medication adherence, using claim reversals as a proxy measure. METHODS: A cross-sectional study was completed using a sample of reversed claims from the Pharmaceutical Assistance Contract for the Elderly (PACE) program for September 2014. The total number of reversed claims for new prescriptions (15,966) was categorized by prescription origin (written, telephone, electronic, fax, and pharmacy). Using a chi-square analysis, the reversed claims were compared among prescription origin to determine if there is a difference in the proportion of electronic prescriptions reversed compared with those from other origins. RESULTS: When compared with all other prescription origins, electronic prescriptions (E) were more likely to be reversed at day 0 (E = 50%, any other [AO] = 49%, P < 0.05) and after day 0 (E = 58%, AO = 42%, P < 0.05). CONCLUSIONS: Electronic prescriptions are associated with a higher rate of claim reversals and may reflect poorer initial adherence. Electronic prescriptions may more likely be forgotten or not picked up because they were not presented to the pharmacy by the patient. The growing adoption of electronic prescriptions merits particular attention, since it may be a factor in initial medication adherence in the elderly. DISCLOSURES: This study was not supported by any funding. Peterson reports advisory board and consultancy fees from IMS Health and Pfizer and employment by Genentech. Klaiman is currently employed by AccessMatters. No other financial or other conflicts of interests were reported. Study concept and design were primarily contributed by Forestal, along with Klaiman and Peterson. Heller took the lead in data collection, along with Forestal, and data interpretation was performed by Forestal, Klaiman, and Peterson.

Potential for alcohol and prescription drug interactions in older people.

OBJECTIVES: To examine the patterns and prevalence of concomitant alcohol and alcohol-interactive (AI) drug use in older people. DESIGN: Cross-sectional analysis of survey and prescription claims data. SETTING: The Pennsylvania Pharmaceutical Assistance Contract for the Elderly (PA-PACE) program, a state-funded program providing prescription benefits to older people with low to moderate incomes. PARTICIPANTS: A total of 83,321 PA-PACE cardholders (age range 65-106) who were using any prescription medications at the time of survey completion. MEASUREMENTS: All AI drugs were identified using a database of medication warning labels obtained from First DataBank. Prescription drug claims were used to characterize AI drug exposure according to therapeutic class of prescription drug use. A mail survey of PA-PACE cardholders was used to examine alcohol use, as well as sociodemographic and health factors associated with concomitant use of alcohol and AI drugs. RESULTS: Seventy-seven percent of all prescription drug users were exposed to AI medications, with significant variation in exposure and concomitant alcohol use according to therapeutic class. Overall, 19% of AI drug users reported concomitant alcohol use, compared with 26% of non-AI drug users (P<.001). Multinomial logistic regression analyses showed that certain groups of older people, including younger older people, men, and those with higher educational levels, were at greater risk for concomitant exposure to alcohol and AI drugs. CONCLUSION: Many older people use alcohol in combination with AI prescription drugs. Clinicians should warn every patient who is prescribed an AI drug about alcohol-drug interactions, especially those at high risk for concomitant exposure.

Changes in elderly women's health-related quality of life following discontinuation of hormone replacement therapy.

BACKGROUND: Many women have discontinued hormone replacement therapy (HRT) in view of recent findings. The goal of this study was to determine if HRT discontinuation is associated with changes in health-related quality of life (HRQOL) in elderly women. METHODS: We studied women enrolled in Pennsylvania's Pharmaceutical Assistance Contract for the Elderly (PACE) program, linking prescription claims with data from a longitudinal mail survey. HRQOL measures included the number of days out of the last 30 that physical health was not good and analogous measures for mental health, pain, and interference with activities, as well as a composite "healthy days" measure developed by CDC. Longitudinal analyses focused on 2,357 women who completed surveys in both 2002 and 2003, and who used HRT at baseline (mean age = 75.5, range = 65-102). Propensity scores were used to match HRT continuers and discontinuers according to HRT type, demographics, and baseline HRQOL. Analysis of covariance was used to compare HRQOL change in continuers and discontinuers. RESULTS: Between 2002 and 2003, 43% of HRT users discontinued therapy. Analysis of covariance to examine HRQOL change revealed complex interactions with age. Discontinuers aged 65-74 reported greater increases in days in which mental health was not good (p < .05), fewer "healthy days" (p < .05), more days in which health interfered with activities (p < .01), and more days with pain (p < .01). Among women aged 75-84, HRT discontinuers reported more days in which physical health was not good (p < .01); no other significant effects were observed in this group. Relative to HRT continuers, discontinuers aged 85 and older experienced apparent HRQOL improvements following cessation, with fewer days in which physical health was not good (p < .01), fewer days of poor mental health (p < .05), and more "healthy days" (p < .01). CONCLUSIONS: These results suggest that there are substantial age differences in response to HRT discontinuation. While women aged 65-74 experienced apparent declines in HRQOL following HRT cessation, women aged 85 and older experienced relative improvements. The HRQOL declines observed among younger women underscore the importance of communication between clinicians and patients throughout the discontinuation process. These results also demonstrate the value of HRQOL surveillance as a component of health program administration.

Dehydration in black and white older adults using diuretics.

PURPOSE: To assess the association between dehydration and ethnicity in older adults; and to determine if diuretic use can help explain the disparity between blacks and whites in diagnosis of dehydration. METHODS: We conducted a case-control study in black and white older adults in a pharmaceutical assistance program who were hospitalized during 1997. Cases were all those diagnosed with dehydration (N=9186). Randomly selected controls were 4:1 frequency matched to cases by sex and age group (N(Total)=45585). RESULTS: Patients taking loop, potassium-sparing, thiazide or combination diuretics were more likely to have a diagnosis of dehydration. Dehydration diagnosis was associated with being black (odds ratio (OR)=1.49, 95% confidence interval (CI), 1.36-1.63, p<.001), independent of diuretic use or dosage. That association remained when examining loop (OR=1.36, 95% CI, 1.10-1.63, p<.004) and thiazide diuretic users (OR=1.59, 95% CI, 1.09-2.34, p=.017), but not potassium-sparing or combination diuretic users. CONCLUSION: Diuretic use is significantly associated with dehydration diagnosis, but the greater likelihood of older blacks being diagnosed with dehydration is independent of diuretic use. The increased risk of morbidity and mortality associated with dehydration suggests that further examination of the root cause of this disparity in risk is warranted.

Health-related quality of life among older adults with arthritis.

BACKGROUND: Health-related quality of life (HRQOL) is a key outcome in arthritis, but few population-based studies have examined the relationship of specific arthritic conditions, such as osteoarthritis (OA) and rheumatoid arthritis (RA) with HRQOL. METHODS: Older adults in Pennsylvania completed a mail version of the Centers for Disease Control and Prevention (CDC) HRQOL modules. Medicare data were used to identify subjects with OA, RA, and no arthritis diagnosis. We compared HRQOL responses among these groups, and we also examined relationships of demographic characteristics to HRQOL among subjects with arthritis. RESULTS: In analyses controlling for demographic characteristics and comorbidity, subjects with OA and RA had poorer scores than those without arthritis on all HRQOL items, including general health, physical health, mental health, activity limitation, pain, sleep, and feeling healthy and full of energy. HRQOL scores were also lower for those with RA compared to OA. Among individuals with arthritis, all subject characteristics (including age, race, sex, nursing home residence, marital status, income, and comorbid illnesses) were significantly related to at least one HRQOL item. Older age, nursing home residence, and greater comorbidity were the most consistently associated with poorer HRQOL. CONCLUSIONS: Results of this study show that both OA and RA have a significant impact on multiple dimensions of HRQOL among older adults. Results also suggest the CDC HRQOL items are suitable for use among older adults and in mail surveys. Due to the rising number of older adults in many countries, the public health burden of arthritis is expected to increase dramatically. Efforts are needed to enhance access to medical care and disseminate self-management interventions for arthritis.

Changes in related drug class utilization after market withdrawal of cisapride.

BACKGROUND: Recent Food and Drug Administration-mandated and company-initiated withdrawals of drug products from the marketplace have had an impact on utilization in related drug classes. OBJECTIVE: To investigate the impact of withdrawal of the prokinetic agent cisapride (Propulsid) on utilization of other gastrointestinal (GI) agents. STUDY DESIGN: A longitudinal, retrospective study using electronic prescription data from a state-funded geriatric prescription benefit program. PATIENTS AND METHODS: Prescription claims for 2644 patients using cisapride between January 10, 2000, and October 1, 2000, were analyzed with respect to points in time at which (1) prospective drug utilization review edits were implemented denying reimbursement of cisapride because of drug interactions, (2) the manufacturer announced its intent to cease production, and (3) the agent was withdrawn from the market. Prevalence of use, claims volume, and expenditures were compared for cisapride, proton pump inhibitors, histamine-2 receptor antagonists, and the prokinetic agent metoclopramide during these periods. RESULTS: Use of cisapride decreased precipitately even before implementation of a "medical exception only" reimbursement policy. After the change in policy, metoclopramide use increased, although this increase was not proportional to cisapride's decline. Although total GI expenditures declined within the cisapride cohort, this change had little impact on overall program GI expenditures. CONCLUSIONS: The loss of cisapride did not significantly affect program-wide costs for GI drugs. However, the withdrawal of cisapride appears to have resulted in increased use of metoclopramide, a medication with a more serious adverse effect profile than cisapride. Further study is needed to evaluate the long-term clinical impact of such therapy changes.

Among older adults, the responsiveness of self-rated health to changes in Charlson comorbidity was moderated by age and baseline comorbidity.

OBJECTIVE: To examine the impact of changes in comorbidity--as measured by the Charlson comorbidity index--on self-rated health in a large sample of community-dwelling elderly over a 1-year period, and to examine the differential effects of changes in specific Charlson diagnostic categories. STUDY DESIGN AND SETTING: Longitudinal survey data on self-rated health were linked with Medicare inpatient, outpatient, and physician visit data for 30,535 U.S. elderly residing in Pennsylvania. Multivariate logistic regression with fractional polynomials was used to model relationships involving baseline and changing Charlson comorbidity with self-rated health decline, and to evaluate covariate interactions. RESULTS: Comorbidity change was associated with greater likelihood of worsened self-rated health, but the relationship was nonlinear and was moderated by age and baseline comorbidity. The impact of comorbidity change appeared to be less among older individuals and those with higher baseline comorbidity. Declines in self-rated health were most likely following new diagnoses for metastatic tumors, paralysis, and dementia. CONCLUSION: Self-rated health is responsive to changes in Charlson comorbidity, but nonlinearity and interactions suggest complexity in how elderly respond to comorbidity change. Younger individuals and those with initially low comorbidity are more likely to reduce self-ratings of health following new diagnoses for chronic conditions.

Gender differences in NSAID use among older adults with osteoarthritis.

BACKGROUND: Nonsteroidal antiinflammatory drugs (NSAIDs) are the most commonly prescribed medications for the treatment of osteoarthritis (OA). Little is known about whether there are important gender differences in NSAID use among patients with OA. OBJECTIVE: To examine gender differences in patterns of NSAID use among older adults (>or=65 y) with OA. METHODS: Subjects (n = 11298) were members of a statewide prescription drug plan who responded to a health-related quality-of-life (HRQOL) survey in 1997 and had a physician diagnosis of OA. Gender differences in patterns of NSAID use were examined over a 2-year period. RESULTS: Approximately one-third of the participants filled at least 1 NSAID prescription during the study. Women were significantly more likely to be prescribed an NSAID than men (37% vs. 30%), had a greater total days' supply of NSAIDs, and were more frequently prescribed NSAIDs with greater degrees of cyclooxygenase-2 selectivity. These gender differences persisted in statistical analyses controlling for demographic factors, HRQOL, and gastrointestinal (GI) risk factors. CONCLUSIONS: Results of this study showed significant gender differences in patterns of NSAID use, and these differences were independent of the risk for GI adverse effects and self-reported symptoms. Further research is needed to examine reasons for these gender variations, as well as their impact on the quality of symptom management.

Health-related quality of life and health service use among older adults with osteoarthritis.

OBJECTIVE: To examine the relationship between health-related quality of life (HRQOL) and health service use among older adults with osteoarthritis (OA). METHODS: Subjects were 9,043 Medicare-enrolled survey respondents with a prior International Classification of Diseases, Ninth Revision code for OA. Analyses examined the relationship of 5 Centers for Disease Control and Prevention HRQOL items (general health, mental health, pain, activity limitation, and sleep) to physician visits, prescription analgesic or antiinflammatory use, and arthroplasty during 1 year of followup. RESULTS: In analyses controlling for demographic and health-related variables, greater pain frequency was associated with increased odds of visiting a physician, using analgesic or antiinflammatory drugs, and having arthroplasty (P < 0.001). Poorer general health was associated with increased odds of analgesic or antiinflammatory use but decreased odds of arthroplasty (P < 0.01). More days of activity limitation and poor mental health were associated with decreased odds of analgesic or antiinflammatory use (P < 0.01). CONCLUSION: These HRQOL variables, especially pain frequency, can be valuable tools for estimating future health care use among older adults with OA.

Relationship of health-related quality of life to health care utilization and mortality among older adults.

BACKGROUND AND AIMS: This investigation examined the ability of a four-item Health-Related Quality of Life (HRQOL) scale to predict short-term (30-day) and long-term (1-year) physician visits, hospitalization, and mortality among older adults. METHODS: Subjects included 84065 individuals aged 65 and older who completed a mail version of the Centers for Diseases Control's Behavioral Risk Factor Surveillance System (BRFSS) Core HRQOL Module. HRQOL dimensions represented by the module include global self-rated general health, recent physical health, recent mental health, and recent activity limitation. RESULTS: In analysis of covariance models controlling for demographic factors and comorbidity, the number of physician visits within 30 days and 1 year differed significantly across categories of each HRQOL item. In Cox regression models controlling for the same covariates, all four HRQOL questions were significant predictors of 30-day and 1-year hospitalization and mortality. CONCLUSIONS: These results signify that all four dimensions of HRQOL represented by the BRFSS Core HRQOL Module are important predictors of both short-term and long-term adverse health events among older adults. This brief scale may be particularly useful for assessing the health of older adults in clinical settings and large-scale epidemiological studies.
