RESUMEN

INTRODUCTION: The Florida-California Cancer Research, Education, and Engagement (CaRE2) Health Equity Center is a triad partnership committed to increasing institutional capacity for cancer disparity research, the diversity of the cancer workforce, and community empowerment. This article provides an overview of the structure, process innovations, and initial outcomes from the first 4 years of the CaRE2 triad partnership. METHODS: CaRE2 serves diverse populations in Florida and California using a "molecule to the community and back" model. We prioritize research on the complex intersection of biological, environmental, and social determinants health, working together with scientific and health disparities communities, sharing expertise across institutions, bidirectional training, and community outreach. Partnership progress and outcomes were assessed using mixed methods and four Program Steering Committee meetings. RESULTS: Research capacity was increased through development of a Living Repository of 81 cancer model systems from minority patients for novel cancer drug development. CaRE2 funded 15 scientific projects resulting in 38 publications. Workforce diversity entailed supporting 94 cancer trainees (92 URM) and 34 ESIs (32 URM) who coauthored 313 CaRE2-related publications and received 48 grants. Community empowerment was promoted via outreaching to more than 3000 individuals, training 145 community cancer advocates (including 28 Community Scientist Advocates), and publishing 10 community reports. CaRE2 members and trainees together have published 639 articles, received 61 grants, and 57 awards. CONCLUSION: The CaRE2 partnership has achieved its initial aims. Infrastructure for translational cancer research was expanded at one partner institution, and cancer disparities research was expanded at the two cancer centers.

RESUMEN

BACKGROUND: Use of bariatric surgery has increased dramatically in the USA. However, there are growing concerns regarding the safety outcomes of different bariatric procedures. We aim to compare the safety of sleeve gastrectomy (SG) and Roux-en-Y gastric bypass (RYGB), which includes hospital readmissions, emergency room (ER) visits, gastrointestinal bleeding, and revisional surgery. METHODS: A retrospective cohort analysis was conducted for adults (≥ 18 years) who received SG and RYGB in the USA. We used Truven MarketScan Commercial and Medicare supplemental claims databases from January 1, 2005, to October 1, 2015. To adjust for baseline demographic and clinical characteristics, we used stabilized inverse probability of treatment weighting using propensity score. Cox proportional hazard models was used to compare safety outcomes between SG and RYGB after bariatric surgery. RESULTS: A total of 194,248 patients met inclusion criteria; 79,813 patients (41%) received SG and 114,435 patients (59%) received RYGB. The use of SG was associated with a significantly lower 30-day hospital readmission rate [adjusted hazard ratios (aHRs) 0.77; 95% confidence interval (CI), 0.74-0.81] and ER visits [aHR, 0.82; 95% CI, 0.80-0.83], and decreased risk of gastrointestinal bleeding [aHR, 0.87; 95% CI, 0.78-0.98] compared to RYGB. However, SG was associated with an increased risk of revisional surgery, compared to RYGB [aHR,1.21; 95% CI, 1.08-1.35]. CONCLUSIONS: Among patients receiving bariatric surgery in a real-world setting, SG was associated with lower complication rate but a higher risk of revisional surgery compared to RYGB. Further longitudinal studies are needed to assess long-term findings.

RESUMEN

PURPOSE: While renal risk associated with short-term use of non-steroidal anti-inflammatory drugs (NSAID) has been anecdotally documented, no conclusive evidence is available on the renal safety, especially among hospitalized patients with reduced renal function. This study is to evaluate the risk of acute kidney injury (AKI) associated with NSAID use in hospital. METHODS: A retrospective matched cohort study utilizing electronic health records from two large academic tertiary-care hospitals was conducted. We defined AKI based on changes in SCr according to published AKI criteria. The hospital acquired AKI risk associated with inpatient NSAID use was assessed using a time-dependent Cox proportional hazard regression in pooled cohort as well as two sub cohorts stratified by baseline renal function. RESULTS: A total of 18,794 admissions were included in the final cohort. Of 9397 admissions exposed to NSAIDs, 7914 and 1483 admissions were in the "without" and "with baseline renal impairment" cohort, with the same number of matching non-exposed admissions in each of the stratified cohort. The AKI incidences were 6 and 22 events per 1000 patient-days in "without" and "with preexisting renal impairment" cohort, respectively. The adjusted analyses suggested that NSAID use increased AKI risk in patients with preexisting renal impairment (hazard ratio [HR]: 1.38 [1.04-1.83]) but not in the patients without preexisting renal impairment (HR: 0.83 [95% CIs: 0.63-1.08]) or in the pooled cohort (HR: 1.01 [95% CIs: 0.83-1.24]). CONCLUSION: Our findings suggested that NSAID use is associated with an increased risk of AKI in the hospitalized patients with preexisting renal impairment but the association is not statistically significant in those who have preserved renal function. Further randomized controlled trials are needed to validate these observational findings.

RESUMEN

OBJECTIVE: Pharmacists are positioned to evaluate and educate patients regarding medication adherence; however, opportunities exist to leverage a collaborative approach in eliciting barriers encountered by patients, especially in minority groups. Community health workers (CHWs) are individuals from the communities who form relationships with patients and help increase their access to health care resources. This study aimed to evaluate the effectiveness of a collaboration between CHWs and pharmacists in identifying and addressing medication adherence barriers faced by hypertensive patients. METHODS: After receiving training in medication therapy management support, CHWs from the South East American Indian Council collaborated with students and pharmacists from the Center for Quality Medication Management at the University of Florida to identify and address medication adherence barriers encountered by hypertensive patients who were mainly Native American or black. The CHWs documented information from the patient interviews during the initial and follow-up visits. The team collaborated to identify intervention opportunities on the basis of the adherence barriers identified. Follow-up visits were conducted to measure progress. RESULTS: Thirty-three hypertensive patients with or without diabetes were included in the study. The pharmacists, in partnership with the CHWs, offered 149 interventions related to medication adherence barriers. The most commonly identified barriers included forgetfulness, adverse effects, and knowledge concerns. By the final visits, 75.6% of the barriers related to antihypertensive medications and 63.9% of the barriers related to antidiabetic medications were resolved. In addition, a paired t test indicated a significant difference in the mean blood pressure values (P = 0.006 for systolic and P = 0.008 for diastolic) recorded at the initial (mean = 136/85.7 mm Hg) and final (mean = 130.1/81.2 mm Hg) visits. CONCLUSION: The findings of this pilot project support the collaboration between pharmacists and CHWs to help improve medication adherence and patient outcomes. Additional research is recommended to validate these study findings.

RESUMEN

OBJECTIVES: Despite progress in addressing health disparities among vulnerable populations, minority populations are at risk for chronic health conditions associated with multiple determinants of health, which affects their health status and access to care. We offer a potential solution, which creates an unconventional medical team between a pharmacist and a community health worker (CHW). We explore weaknesses and challenges in our medication use system in the context of adherence as a drug therapy problem, the role of culture in shaping medication use, and finally offer a unique paradigm for a collaborative interprofessional team consisting of CHWs and pharmacists. SUMMARY: Medication adherence is far from optimal, especially in minority ethnic populations. Members of an ethnic group may acquire beliefs about illness consistent with their culture's shared customs. These findings intimate that ethnocultural minority groups may have their own remedies for illness that shape their decision to use medications as prescribed. An interprofessional team in which CHWs and pharmacists collaborate offers an opportunity to improve the effectiveness of pharmacists to address adherence-related problems, especially among minority populations in which culturally determined beliefs can shape medication use decisions. This approach holds promise because CHWs are usually embedded within the community in which their patients live, having experienced the same life experiences. These shared experiences may lead CHWs to uncover medication use practices that pharmacists are not able to discover on their own because the relationship with their patients is often not authentic, which, for many minority patients, can only be established through shared experiences. CONCLUSION: This paper argues that creating teams of CHWs and pharmacists will help address challenges in achieving health equity and health disparities among vulnerable populations in the medication use system.

RESUMEN

PURPOSE: The state-assigned Case ID number in the Medicaid Analytic eXtract (MAX) allows for potential linkage of mothers to infants. No validation of respective linkage algorithms is available. We established and validated an algorithm within MAX that links mothers to infants and to identify factors influencing successful mother-infant linkage. METHODS: We identified all mother-infant pairs in FL and TX birth certificates records (BCR) that could be linked individually to MAX records (1999-2005 for FL and 1999-2010 for TX) based on Social Security Number (gold standard pairs). Case ID linkage performance was evaluated as the proportion of gold standard mother-infant pairs that were identified by the algorithm (sensitivity) and the proportion of algorithm defined mother-infant pairs that were correctly linked. Generalized estimating equations were used to calculate the probability for successful Case ID algorithm linkage versus non-linkage using maternal and infant characteristics. RESULTS: We identified 323,160 gold standard pairs in FL BCR and MAX and 1,025,350 in TX BCR and MAX. Depending on Medicaid enrollment the algorithm sensitivity ranged from 85.51% to 87.96% in FL and 19.60% to 35.75% in TX. In both states, positive predictive value exceeded 99%, regardless of enrollment periods. Determinants for successful linkage varied across states, but suggested better results for younger mothers, minority women, and those with lower educational achievement. CONCLUSIONS: Our algorithm can correctly link liveborn infants to their mothers. The algorithm's sensitivity in identifying pairs varied across states, but PPV was consistently high. Linkage performance was associated with certain characteristics that may affect representativeness of successfully linked pairs.

RESUMEN

PURPOSE: The objective of the study was to determine the risk of sudden sensorineural hearing loss (SNHL) associated with use of phosphodiesterase type 5 (PDE5) inhibitors. METHODS: We conducted a retrospective cohort study in the MarketScan Commercial Claims and Encounters Database including adult men who initiated a PDE5 inhibitor (n = 377,722) and 1,957,233 nonusers between 1998 and 2007. Periods of drug exposure were assessed on a weekly basis based on pharmacy billing records, assuming use of 1 dose per week (current use). Incident sudden SNHL was defined based on inpatient or outpatient visits with International Classification of Diseases, Ninth Revision, Clinical Modification codes 389.1x, 389.2x, or 388.2 plus ≥2 procedure codes for audiometric hearing testing within ±30 days of sudden SNHL diagnosis. We used age- and propensity score-adjusted Cox proportional hazards model to evaluate the risk of sudden SNHL during periods of current or recent use compared with that of nonuse. We conducted sensitivity analyses by varying the assumed drug utilization frequency and sudden SNHL case definition. RESULTS: We evaluated 1233 sudden SNHL cases, resulting in an incidence of 4.35, 5.58, and 2.38 per 10,000 person-years for current, recent, and nonuse of PDE5 inhibitors, respectively. Compared with nonuse, the adjusted hazard ratio was 1.25 (1.01-1.55) for current use with a risk difference of 1.97 (1.12-2.82) per 10,000 person-years. For recent use, the adjusted hazard ratio was 1.60 (1.33-1.94) and risk difference was 3.19 (2.24-4.14). Estimates were consistent across the sensitivity analyses. CONCLUSIONS: Use of PDE5 inhibitors is associated with a small but significantly increased risk of sudden SNHL.

RESUMEN

PURPOSE: To explore changes in stimulant utilization and pre-treatment electrocardiography (ECG) screening in response to cardiovascular (CV) safety concerns. METHODS: Two source populations were established from Florida Medicaid Fee-for-service beneficiaries between 2001 and 2008: approximately 44 571 newly diagnosed attention deficit/hyperactivity disorder patients and 33 000 new stimulant users. Time-series design and Joinpoint analysis were used to describe monthly trend changes in stimulant initiation, persistence, dosing, and pre-treatment ECG screening. RESULTS: Initial and maintenance daily dose declined 6 mg (95% confidence interval [CI] -14 to -1.9) methylphenidate (MPH) equivalent dose from a steady 27 mg after Canada withdrew Adderall XR in February 2005; the trend rebounded to a daily dose of 23 mg, after the remarketing of Adderall XR and a debate in the US over issuing a boxed warning on stimulant CV safety in early 2006. Monthly initiation increased 3.9% (CI -1.0 to 9.1) after the boxed warning debate to 54 per 100 patients per month (CI 44 to 68), but declined 2.4% (CI -3.6 to -1.2) after requirement of medication guides in February 2007. Monthly ECG screening increased 3.2% (CI 2.3 to 4.2) after Adderall XR withdrawal and further increased 13% (CI 4 to 23) after the American Heart Association recommended pre-treatment ECG screening to 40 per 100 patients per month (CI 17 to 48). CONCLUSIONS: The first signal of stimulant CV safety concerns was followed by varying responses depending on the outcome measure used, suggesting that patients and physicians responded at different times after the publicity of safety concerns. Clinical consequences of the changes are uncertain. Copyright © 2015 John Wiley & Sons, Ltd.

RESUMEN

OBJECTIVE: To examine the comparative effectiveness of inhaled long-acting beta-agonist (LABA), inhaled corticosteroid (ICS), and ICS/LABA combinations. METHODS: We used a retrospective cohort design of patients older than 12 years with asthma diagnosis in the Clinical Practice Research Datalink to evaluate asthma-related morbidity measured by oral corticosteroid (OCS) initiation within 12 months of initiating LABAs, ICSs, or ICSs/LABAs. Asthma severity 12 months before drug initiation (use of OCSs, asthma-related hospital or emergency department visits, and number of short-acting beta-agonist prescriptions) and during follow-up (short-acting beta-agonist prescriptions and total number of asthma drug classes) was adjusted as a time-varying variable via marginal structural models. RESULTS: A total of 51,103 patients with asthma were followed for 12 months after receiving first prescription for study drugs from 1993 to 2010. About 92% initiated ICSs, 1% initiated LABAs, and 7% initiated ICSs/LABAs. Compared with ICSs, LABAs were associated with a 10% increased risk of asthma exacerbations requiring short courses of OCSs (hazard ratio [HR] 1.10; 95% confidence interval [CI] 1.07-1.18). ICS/LABA initiators were 62% less likely than ICS initiators (HR 0.38; 95% CI 0.12-0.66) and 50% less likely than LABA initiators to receive OCS prescriptions for asthma exacerbations (HR 0.50; 95% CI 0.14-0.78). CONCLUSIONS: In concordance with current asthma management guidelines, inhaled LABAs should not be prescribed as monotherapy to patients with asthma. The findings suggest the presence of time-dependent confounding by asthma severity, which was accounted for by the marginal structural model.

RESUMEN

In normal animals, operant conditioning of the spinal stretch reflex or the H-reflex has lesser effects on synergist muscle reflexes. In rats and people with incomplete spinal cord injury (SCI), soleus H-reflex operant conditioning can improve locomotion. We studied in normal humans the impact of soleus H-reflex down-conditioning on medial (MG) and lateral gastrocnemius (LG) H-reflexes and on locomotion. Subjects completed 6 baseline and 30 conditioning sessions. During conditioning trials, the subject was encouraged to decrease soleus H-reflex size with the aid of visual feedback. Every sixth session, MG and LG H-reflexes were measured. Locomotion was assessed before and after conditioning. In successfully conditioned subjects, the soleus H-reflex decreased 27.2%. This was the sum of within-session (task dependent) adaptation (13.2%) and across-session (long term) change (14%). The MG H-reflex decreased 14.5%, due mainly to task-dependent adaptation (13.4%). The LG H-reflex showed no task-dependent adaptation or long-term change. No consistent changes were detected across subjects in locomotor H-reflexes, EMG activity, joint angles, or step symmetry. Thus, in normal humans, soleus H-reflex down-conditioning does not induce long-term changes in MG/LG H-reflexes and does not change locomotion. In these subjects, task-dependent adaptation of the soleus H-reflex is greater than it is in people with SCI, whereas long-term change is less. This difference from results in people with SCI is consistent with the fact that long-term change is beneficial in people with SCI, since it improves locomotion. In contrast, in normal subjects, long-term change is not beneficial and may necessitate compensatory plasticity to preserve satisfactory locomotion.

RESUMEN

OBJECTIVE To assess the association between unhealthy lifestyle-related behaviors in patients and the pharmacist's professional obligation for providing care. DESIGN Repeated measures ANOVA was used to examine the effect of severity of lifestyle disease on professional obligation. SETTING Four live continuing education programs on law and management conducted in the state of Florida. PARTICIPANTS 488 Florida pharmacists were surveyed with 65% completing the survey. MAIN OUTCOME MEASURES Pharmacists' opinions based on lifestyle-related diseases classified as follows: low lifestyle-related disease (low LD): nonsmoker with asthma who is adherent with asthma medications; moderate (mod) LD: nonsmoker with asthma who is nonadherent with asthma medications; high LD: smoker with asthma who is adherent with asthma medications. RESULTS The difference between the scales for measuring professional obligation for low and mod LD was significant, with pharmacists reporting greater professional obligation for low versus mod LD. The difference between professional obligation for low and high LD was significant, with pharmacists reporting greater professional obligation for low than high LD. The difference between professional obligation for mod and high LD was significant, with pharmacists reporting a higher professional obligation for mod than high LD. CONCLUSION The differences in professional obligation between the three patient scenarios were small but statistically significant. The findings suggest that certain patient behaviors, such as smoking or medication nonadherence, can have a negative effect on pharmacists' sense of professional obligation to the patient.

RESUMEN

OBJECTIVE: To examine HbA1c levels and adherence to oral glucose-lowering medications and their association with future HbA1c levels among American Indian adults with type 2 diabetes (T2D) receiving medications at no cost from a tribal health care system. RESEARCH DESIGN AND METHODS: Tribal citizens with T2D who used Choctaw Nation Health Services Authority (CNHSA) and Pharmacies and had HbA1c data during 2017-2018 were included in this study. Medication adherence (proportion of days covered [PDC] ≥0.80) was calculated using 2017 CNHSA electronic health record data. RESULTS: Of the 74,000 tribal citizens living on tribal lands, 4,560 were eligible; 32% had HbA1c at or below target (≤7%), 36% were above target (>7 to ≤9%), and 32% were uncontrolled (>9%) in 2017. The percentage of patients with PDC ≥0.80 was 66% for those using biguanides, 72% for sulfonylureas, 75% for dipeptidyl peptidase 4 inhibitors, and 83% for sodium-glucose cotransporter 2 inhibitors. The proportion of patients with HbA1c at or below target increased slightly from 32% in 2017 to 42% in 2018. Higher average PDC in 2017 was associated with lower HbA1c levels in 2018 (ß = -1.143; P < 0.001). CONCLUSIONS: Medication adherence was higher than that found in previous studies using self-report methods in American Indian populations, although a smaller proportion of patients had HbA1c at or below target relative to U.S. adults with T2D. Medication adherence was associated with improved HbA1c levels for most oral glucose-lowering medication classes. Future studies of American Indians should use both longitudinal prescription data from both electronic health records and pharmacy refills.

RESUMEN

INTRODUCTION: The soleus H-reflex is dynamically modulated during walking. However, modulation of the gastrocnemii H-reflexes has not been studied systematically. METHODS: The medial and lateral gastrocnemii (MG and LG) and soleus H-reflexes were measured during standing and walking in humans. RESULTS: Maximum H-reflex amplitude was significantly smaller in MG (mean 1.1 mV) or LG (1.1 mV) than in soleus (3.3 mV). Despite these size differences, the reflex amplitudes of the three muscles were positively correlated. The MG and LG H-reflexes were phase- and task-dependently modulated in ways similar to the soleus H-reflex. CONCLUSIONS: Although there are anatomical and physiological differences between the soleus and gastrocnemii muscles, the reflexes of the three muscles are similarly modulated during walking and between standing and walking. Our findings support the hypothesis that these reflexes are synergistically modulated during walking to facilitate ongoing movement.

RESUMEN

Through operant conditioning, spinal reflex behaviors can be changed. Previous studies in rats indicate that the sensorimotor cortex and corticospinal tract are essential in inducing and maintaining reflex changes induced through conditioning. In people with incomplete spinal cord injury (SCI), an operant down-conditioning protocol decreased the soleus H-reflex size and improved walking speed and symmetry, suggesting that a partially preserved spinal cord can support conditioning-induced plasticity and benefit from it. This study examined whether down-conditioning can decrease the soleus H-reflex in people with supraspinal injury (i.e., cortical or subcortical stroke). Operant down-conditioning was applied to the soleus H-reflex in a cohort of 12 stroke people with chronic spastic hemiparesis (>12 months from stroke onset of symptoms). Each participant completed 6 baseline and 30 conditioning sessions over 12 weeks. In each baseline session, 225 control H-reflexes were elicited without any feedback on H-reflex size. In each conditioning session, 225 conditioned H-reflexes were elicited while the participant was asked to decrease H-reflex size and was given visual feedback as to whether the resulting H-reflex was smaller than a criterion value. In six of 12 participants, the conditioned H-reflex became significantly smaller by 30% on average, whereas in other 6 participants, it did not. The difference between the subgroups was largely attributable to the difference in across-session control reflex change. Ten-meter walking speed was increased by various extent (+0.04 to +0.35, +0.14 m/s on average) among the six participants whose H-reflex decreased, whereas the change was 0.00 m/s on average for the rest of participants. Although less than what was seen in participants with SCI, the fact that conditioning succeeded in 50% of stroke participants supports the feasibility of reflex down-conditioning in people after stroke. At the same time, the difference in across-session control reflex change and conditioning success rate may reflect a critical role of supraspinal activity in producing long-term plasticity in the spinal cord, as previous animal studies suggested.

RESUMEN

BACKGROUND: American Indian adults have the highest prevalence of type 2 diabetes (T2D) in any racial or ethnic group and experience high rates of comorbidities. Uncontrolled cardiometabolic risk factors-insulin resistance, resulting in impaired glucose tolerance, dyslipidemia, and hypertension-increase the risk of mortality. Mortality is significantly reduced by glucose- and lipid-lowering and antihypertensive medication adherence. Medication adherence is low among American Indian adults living in non-Indian Health Service health care settings. Virtually nothing is known about the nature and extent of medication adherence among reservation-dwelling American Indian adults who primarily receive their medications without cost from Indian Health Service or tribal facilities. Electronic health records (EHRs) offer a rich but underused data source regarding medication adherence and its potential to predict cardiometabolic control indicators (C-MCIs). With the support of the Choctaw Nation of Oklahoma (CNO), we address this oversight by using EHR data generated by this large, state-of-the-art tribal health care system to investigate C-MCIs. OBJECTIVE: Our specific aims are to determine, using 2018 EHR data, the bivariate relationships between medication adherence and C-MCIs, demographics, and comorbidities and each C-MCI and demographics and comorbidities; develop machine learning models for predicting future C-MCIs from the previous year's medication adherence, demographics, comorbidities, and common laboratory tests; and identify facilitators of and barriers to medication adherence within the context of social determinants of health (SDOH), EHR-derived medication adherence, and C-MCIs. METHODS: Drawing on the tribe's EHR (2018-2021) data for CNO patients with T2D, we will characterize the relationships among medication adherence (to glucose- and lipid-lowering and antihypertensive drugs) and C-MCIs (hemoglobin A1c ≤7%, low-density lipoprotein cholesterol <100 mg/dL, and systolic blood pressure <130 mm Hg); patient demographics (eg, age, sex, SDOH, and residence location); and comorbidities (eg, BMI ≥30, cardiovascular disease, and chronic kidney disease). We will also characterize the association of each C-MCI with demographics and comorbidities. Prescription and pharmacy refill data will be used to calculate the proportion of days covered with medications, a typical measure of medication adherence. Using machine learning techniques, we will develop prediction models for future (2019-2021) C-MCIs based on medication adherence, patient demographics, comorbidities, and common laboratory tests (eg, lipid panel) from the previous year. Finally, key informant interviews (N=90) will explore facilitators of and barriers to medication adherence within the context of local SDOH. RESULTS: Funding was obtained in early 2022. The University of Florida and CNO approved the institutional review board protocols and executed the data use agreements. Data extraction is in process. We expect to obtain results from aims 1 and 2 in 2024. CONCLUSIONS: Our findings will yield insights into improving medication adherence and C-MCIs among American Indian adults, consistent with CNO's State of the Nation's Health Report 2017 goal of reducing T2D and its complications.

RESUMEN

Important basic science research is being conducted that has direct implications for the rehabilitation of patients, but the translation of this research to change clinical practice does not occur automatically. Advisory panels to the National Center for Medical Rehabilitation Research acknowledge a need for basic and applied research related to the factors underlying coordinated movements, such as the interactions of the neuromuscular and musculoskeletal systems. In this paper, we briefly describe recent studies that have examined the preceding interaction and discuss some basic issues related to the translation of these experiments to the clinic. More importantly, the main purpose of this paper is to discuss models/ways to translate basic science to clinical practice in a two-way and informed interaction between basic scientists and clinicians.

RESUMEN

Initial legalization of medical marijuana (MM) in Florida required providers to submit initial and follow-up treatment plan forms to the University of Florida to support research on MM safety and efficacy. This study retrospectively analyzed all treatment plan forms submitted between program inception (August 2016) through July 2017 and describes early Florida MM registrants by clinical conditions and prescription drug utilization. Among 7,548 unique treatment plans, the initial visit was characterized by registrants who were mostly white (83.7%), 52.3 (SD 16.4) years of age on average, and who were assessed by the provider as at least moderately ill (79.6%). Musculoskeletal and spasticity-related conditions (44.8%), chronic pain (41.9%), and mental health disorders (17.0%) were the most frequent medical complaints for seeking MM treatment with more than one condition per patient possible. One in four (25.9%) patients reported use of prescription opioids and over one-fifth of patients frequently utilized at least one psychotropic medication as well as cardiovascular agents. There were 2,075 unique follow-up plans available which were mostly characterized by clinical improvement and reported reductions in utilization of some drug classes. Further research is needed to guide clinicians on the risks and benefits of MM used concomitantly with prescription drugs.

RESUMEN

BACKGROUND: Since the 1990s, the number of bariatric surgeries has dramatically increased, including the number of bariatric centers in the United States; no recent studies have yet assessed trends of bariatric surgery. This study aims to assess the trends of bariatric surgery and the change in utilization by the type of surgery, from 2006 to 2015, using real-world data. METHODS: A cross-sectional analysis of MarketScan databases of privately insured beneficiaries aged equal to or more than 18 years, to assess the annual incidence rate of bariatric surgery type of surgery from 2006 to 2015. Linear regression analysis was used to assess the significance of bariatric surgery changes over time. RESULTS: A gradual increase in overall bariatric surgery was observed from 43.5 per 100,000 in 2006 to 70.6 per 100,000 in 2009. This increasing trend plateaued from 2010 to 2015. Among all bariatric surgeries performed, the sleeve gastrectomy showed a significant increase from (n = 596) 11% in 2006 to (n = 15,425) 70% in 2015 (P < .001), whereas there was a decrease in Roux-en-Y from (n = 10,129) 45% in 2010 to (n = 5074) 24% in 2015 (P < .001). CONCLUSION: Utilization of bariatric surgery showed a gradual increase in the first 5 years, with steady rates in the last 5 years of the study period. Sleeve gastrectomy and Roux-en-Y remain the most performed bariatric procedures. Laparoscopic surgery continues to dominate bariatric surgery compared with open surgery.

RESUMEN

BACKGROUND: Hypertension affects over 50 million Americans, with only 50% of patients being adequately controlled. Several pharmacist counseling and pharmacist-physician comanagement studies have documented that community pharmacist interventions improve blood pressure (BP) management. OBJECTIVE: To determine whether community pharmacists can improve clinical endpoints including hypertension control, drug therapy dosing, adherence to prescribed regimens, adverse drug reaction incidence, patient understanding, response to therapy, and quality-of-life. METHODS: The program included the education and training of a group of 18 chain community pharmacists in hypertension therapies, monitoring, and management. Protocols and documentation tools were based on nationally accepted clinical practice guidelines for hypertension in place at the time of the study. Pharmaceutical care (PC) was then compared with usual care (UC) over a 12-month period. RESULTS: The study initially enrolled 180 PC and 196 UC patients, with 44% (PC) and 32% (UC) of the patients reporting a final BP measurement. A larger proportion (50%) of PC patients who had poorly controlled hypertension at baseline (>140/90 mm Hg) were controlled compared with UC patients (22%). The average reduction in systolic BP was 9.9 mm Hg in PC patients compared with 2.8 mm Hg in UC patients (p < 0.05). Changes in diastolic BP were similar in the PC and UC groups. Based on patient self-report, PC patients were more likely to say that they take their medicines as prescribed compared with UC patients (p < 0.05). The 1- to 6-month antihypertensive adherence rate was higher in PC patients (0.91 +/- 0.15) compared to UC patients (0.78 +/- 0.30) (p = 0.02); there was no significant difference in adherence rate during the 7- to 12-month period. CONCLUSIONS: Community pharmacists can positively affect patient medication adherence during the 6-month period following counseling by a pharmacist along with an improvement in patient BP. However, there is much room for improvement in PC programs and in the number of patients who properly adhere to their medications.

RESUMEN

Pneumococcal vaccination rates remain sub-optimal in high-risk adult populations. This analysis quantified "missed opportunities," defined as number of healthcare encounters in unvaccinated patients who are recommended to be vaccinated. The 2015 National Health Interview Survey was used to assess vaccination status from adults 18-64 with risk factor and adults ≥65 years-old. In older adults, there was a mean of 5.15 (95% CI: 4.90-5.39) healthcare visits that could be opportunities for pneumococcal vaccination. In adults 18-64 years at high risk, there was a mean of 4.83 (95% CI: 4.66-4.99). Healthcare providers should take advantage of patient interactions to increase vaccination rates.
