Pharmacist-led medication reconciliation at patient discharge: a tool to reduce healthcare utilization? an observational study in patients 65 years or older

Background

Older patients often experience adverse drug events (ADEs) after discharge that may lead to unplanned readmission. Medication Reconciliation (MR) reduces medication errors that lead to ADEs, but results on healthcare utilization are still controversial. This study aimed to assess the effect of MR at discharge (MRd) provided to patients aged over 65 on their unplanned rehospitalization within 30 days and on both patients’ experience of discharge and their knowledge of their medication.

Methods

An observational multicenter prospective study was conducted in 5 hospitals in Brittany, France.

Results

Patients who received both MR on admission (MRa) and MRd did not have significantly fewer deaths, unplanned rehospitalizations and/or emergency visits related to ADEs (OR = 1.6 [0.7 to 3.6]) or whatever the cause (p = 0.960) 30 days after discharge than patients receiving MRa alone. However, patients receiving both MRa and MRd were more likely to feel that their discharge from the hospital was well organized (p = 0.003) and reported more frequently that their community pharmacist received information about their hospital stay (p = 0.036).

Conclusions

This study found no effect of MRd on healthcare utilization 30 days after discharge in patients over 65, but the process improved patients’ experiences of care continuity. Further studies are needed to better understand this positive impact on their drug care pathway in order to improve patients’ ownership of their drugs, which is still insufficient. Improving both the interview step between pharmacist and patient before discharge and the transmission of information from the hospital to primary care professionals is needed to enhance MR effectiveness.

Is there a survival difference between older adult and younger adult patients with locally advanced gastric cancer with the same lymph node ratio?

OBJECTIVE

The aim of this study was to clarify the prognostic value of the pathological lymph node ratio for older adult and younger adult gastric cancer patients and to evaluate whether there is a difference in the survival of patients with the same lymph node ratio (LNR).

MATERIALS AND METHODS

A total of 222 patients diagnosed with locally advanced gastric cancer who underwent upfront gastrectomy without neoadjuvant chemotherapy and had negative surgical margins were included. The patients were divided into two groups according to age. Clinicopathological properties of the two groups were compared. Potential prognostic factors affecting survival were analyzed. Subsequently, the effect of lymphadenectomy and LNR on survival in both groups was evaluated.

RESULTS

Thirty patients with perioperative mortality were excluded and 192 patients were analyzed. Significant differences were detected in terms of hemoglobin and albumin levels between older adult patients and younger adult patients (p < 0.05). Overall survival (OS) was significantly worse in older adult patients (22 months vs. 67 months, p < 0.001). The survival rates in older adult patients were significantly lower from those of younger adult in the subgroup LNR Stage 2 (12.1% vs. 47.9%, p = 0.004) and LNR Stage 3 classification (9.1% vs. 34.1%, p = 0.039). LNR was found to be significant for OS with a cut-off point of 0.18.

CONCLUSION

A survival difference was found between the older adult and younger adult patients with the same LNR. LNR was found to be an independent factor for survival especially in older adult patients. Survival was found to be further decreased in older adult patients compared to younger adult patients with increasing LNR.

Based on the Beers Criteria 2019 Edition Over-the-Counter Drugs Risk Confirmation of Elderly Chinese

Objective

To explore OTC (over-the-counter drugs) in Chinese community pharmacies often causes ADE (adverse drug event) in elderly patients.

Methods

Use the drugs in the Beers Criteria 2019 potentially inappropriate medication use (PIM) list as search terms. Search for drugs registered on the National Medical Products Administration of China website before December 2019 to determine the drugs containing PIM active ingredients and, then, search the Chinese OTC selection and conversion catalog database to determine it as OTC. Two databases are considered to be the same drug if they have the same drug composition.

Results

The incidence of PIM in elderly patients in our community is relatively high, and the management of OTC may be related to risk factors. Statistics found that 71 OTC contained the Beers Criteria ingredients, including 65 chemicals and six Chinese patent medicines. Varieties of compound preparations accounted for 78.9% and cold medicines accounted for 47.9%.

Conclusions

The high detection rate of the Beers Criteria in Chinese OTC suggests that medical practitioners in China, especially community pharmacists, should pay attention to the rational use of OTC in the elderly.

Over-the-counter medication use in residents of senior living communities: A survey study

BACKGROUND

Self-medication with over-the-counter (OTC) products is common among older adults. Although OTC self-medication is a convenient way to manage some health issues, older persons may be at higher risk of experiencing medication-related problems. This study examines the prevalence, practices, and preferences associated with OTC medication use in older adult residents of senior living communities.

OBJECTIVES

The study aimed to examine the characteristics of OTC medication users and to quantify the prevalence, attitudes, perceptions, preferences, and practices regarding OTC medication use and decision-making in 2 senior living communities in central Virginia.

METHODS

The study used survey methodology. A 51-item semistructured questionnaire was designed by the research team of geriatrics specialists, and mixed-methods and evaluation researchers. The questionnaire was administered in-person to participants (N = 88). Descriptive analyses were conducted using SAS 9.4. Characteristics of those using OTC medications as directed by a health professional were compared with those of whom were self-medicating with OTC medications.

RESULTS

Most of the sample were women (55%), black (61%) and had less than or equal to a high school education (55%). Analgesics were the most (76%) prevalent OTC therapeutic category used, and aspirin was the most (65%) prevalent OTC medication. A greater (82%) proportion of respondents reported self-recommended OTC medication use (self-medication with OTC medications) rather than physician recommended use (18%). A high (41%) prevalence of inappropriate use of OTC medications was observed in this sample of older adults. Most (80%) considered OTC medications safe and effective. The pharmacy was the most (93%) commonly reported purchase location to buy an OTC medication. Physicians were the most (90%) commonly reported information source for OTC medications.

CONCLUSION

Considering the high percentage of self-reported self-medication, inappropriate use, and experiences of adverse effects, steps should be taken to develop consumer education and relationships with pharmacists to encourage the responsible use of OTC medications in this population.

Differential Diagnoses and Clinical Implications of Medication Nonadherence in Older Patients with Chronic Kidney Disease: A Review

Older adults with chronic kidney disease (CKD) often have many comorbidities, which requires them to take multiple medications. As the number of daily medications prescribed increases, the risk for polypharmacy increases. Understanding and improving medication adherence in this patient population is vital to avoiding the drug-related adverse events of polypharmacy. The primary objective of this review is to summarize the existing literature and to understand the factors leading to medication nonadherence in older patients with CKD. In this review, we discuss the prevalence of polypharmacy, the current lack of consensus on the incidence of medication nonadherence, the heterogeneity of assessing medication adherence, and the most common differential diagnoses for medication nonadherence in this population. Specifically, the most common differential diagnoses for medication nonadherence in older adults with CKD are (1) medication complexity; (2) cognitive impairment; (3) low health literacy; and (4) systems-based barriers. We provide tailored strategies to address these differential diagnoses and subsequently improve medication adherence. The clinical implications include deprescribing to decrease medication complexity and polypharmacy, utilizing a team-based approach to identify and support patients with cognitive impairment, enriching communication between health providers and patients with low health literacy, and improving health care access to address systems-based barriers. Further research is needed to determine the effects of addressing these differential diagnoses and medication adherence in older adults with CKD.

MedManage: The development of a tool to assist medication reconciliation in a rural primary care clinic

BACKGROUND

Medication reconciliation is a critical step in the health care process to prevent hospital readmission, adverse drug events, and fall prevention. The purpose of the study was to pilot test a medication reconciliation process, MedManage, informed by the Medications at Transitions and Clinical Handoffs (MATCH) toolkit with nursing staff in a rural primary care clinic.

METHODS

The research team conducted 38 chart audits of high-risk patients, and preintervention and postintervention were conducted to assess changes in medications reported by patients. The intervention included a chart audit tool and medication reconciliation tool created by the interdisciplinary team, MedManage, were pilot tested in the clinic.

CONCLUSIONS

The Use of MedManage resulted in improvements in patient reporting of over-the-counter (82% of patients reported previously unrecorded OTCs), PRN medications (3% unreported), and herbal supplements/vitamins (28% reported previously unrecorded vitamins).

IMPLICATIONS FOR PRACTICE

MedManage may be an effective tool to assist clinical nursing staff to attain a more complete and accurate medication list from patients and should be assessed more broadly across rural primary care clinics.

Dietary supplement use by older adults with chronic venous leg ulcers: A retrospective, descriptive study

Nearly 70% of older adults in the U.S. report using ≥1 dietary supplements (DSs) daily. While DSs may have health benefits, there is risk for toxicity or harmful drug-supplement interactions if not taken correctly. Older adults with chronic wounds who use DSs are at increased risk of adverse drug-supplement interactions because they usually have comorbidities requiring polypharmacy management. However, no studies have evaluated DS use in this population. The aim of this retrospective pilot study was to describe DS use by a sample of older adults (n = 40) with chronic venous leg ulcers (CVLUs) who participated in a clinical trial testing the effects of fish oil supplementation on wound healing. At baseline, study personnel assisted all participants in completing an electronic questionnaire about DS use. Descriptive statistics were used to characterize the data. Twenty-five of the 40 participants (62.5%) reported taking ≥1 DS daily. On average, DS users were 65.16 years (SD = 8.51) and the majority were men (64.0%), white (68.0%), and had at least some college education (72.0%). Fifteen (60.0%) reported taking 1-2 DSs/day, and 10 (40.0%) reported taking ≥3/day. The most frequently reported DSs used were multivitamin/mineral complex (60.0%), vitamin D (36.0%), vitamin B complex (28.0%) and calcium (28.0%). Reasons for using DSs were to maintain or improve health (44.0%), improve bone density (12%), and boost the immune system (12%). Supplement users reported consuming an average of 9.12 (SD = 6.46) prescription drugs daily and 21 (84.0%) reported ≥3 chronic health conditions. In summary, DS use in this sample of chronic wound patients was high. Moreover, DS users reported using multiple prescription drugs (2-23/day) concomitantly with DSs. While older adults with CVLUs may benefit from targeted DS therapy, monitoring their DS use to reduce risk for adverse drug-supplement interactions is best practice.

Older Adults in the Cardiac Intensive Care Unit: Factoring Geriatric Syndromes in the Management, Prognosis, and Process of Care: A Scientific Statement From the American Heart Association

Longevity is increasing, and more adults are living to the stage of life when age-related biological factors determine a higher likelihood of cardiovascular disease in a distinctive context of concurrent geriatric conditions. Older adults with cardiovascular disease are frequently admitted to cardiac intensive care units (CICUs), where care is commensurate with high age-related cardiovascular disease risks but where the associated geriatric conditions (including multimorbidity, polypharmacy, cognitive decline and delirium, and frailty) may be inadvertently exacerbated and destabilized. The CICU environment of procedures, new medications, sensory overload, sleep deprivation, prolonged bed rest, malnourishment, and sleep is usually inherently disruptive to older patients regardless of the excellence of cardiovascular disease care. Given these fundamental and broad challenges of patient aging, CICU management priorities and associated decision-making are particularly complex and in need of enhancements. In this American Heart Association statement, we examine age-related risks and describe some of the distinctive dynamics pertinent to older adults and emerging opportunities to enhance CICU care. Relevant assessment tools are discussed, as well as the need for additional clinical research to best advance CICU care for the already dominating and still expanding population of older adults.

Brown Bag Simulation to Improve Medication Management in Older Adults

INTRODUCTION

Medical students must care for aging patients with growing medication lists and need training to address negative patient outcomes associated with polypharmacy. The literature shows that many trainees and practitioners are not confident in their abilities to care for this older population with complex medical conditions. We created an innovative simulation activity to teach safe, effective, and simplified medication management to second-year medical students.

METHODS

We developed the brown bag medication reconciliation simulation to improve self-efficacy and knowledge for trainees working with older adults. The case example was an older patient who presented with his brown bag of medications and prefilled pillbox for a medication reconciliation with his provider. Teams of medical students identified his medication-management errors and determined strategies for resolution. We assessed learner self-efficacy, knowledge, and satisfaction.

RESULTS

A class of 137 second-year medical students completed the simulation. The average number of learners confident about medication management in older adults increased overall by 41%, with a significant increase across all four self-efficacy domains (p < .001). The average percentage of correctly answered knowledge questions significantly increased from 85% on the presurvey to 92% on the delayed postsurvey (p = .009). Learner open-ended feedback indicated high satisfaction with the simulation.

DISCUSSION

The brown bag medication reconciliation simulation increased medical student self-efficacy and knowledge related to medication reconciliation and management for older adults. Interactive simulations like this one may be considered for inclusion in health science curricula to improve skills in medication reconciliation and management.

The missing piece: Clinical pharmacists enhancing the interprofessional nephrology clinic model

OBJECTIVES

To embed pharmacy residents in an interprofessional nephrology clinic to conduct medication reconciliation in targeted high-risk patients with nondialysis kidney disease.

SETTING

This pilot was a prospective quality improvement initiative conducted in an interprofessional outpatient nephrology clinic.

PRACTICE DESCRIPTION

The nephrology clinic team includes nephrology providers, a social worker, and a geriatrician. The team is responsible for the management of conditions such as nondialysis kidney disease, resistant hypertension, acute kidney injury, proteinuria, and nephropathy.

EVALUATION

Primary outcomes included the number and type of medication discrepancies and drug therapy problems identified. Secondary outcomes included the changes in care process directly resulting from the pharmacy residents' recommendations. The perceived value of the pharmacy residents to the interprofessional team was assessed through postintervention anonymous surveys and semistructured interviews.

RESULTS

The pharmacy residents conducted 118 visits for 87 unique patients (mean age 73 years, 97% male) with nondialysis kidney disease (89% stages III-V), polypharmacy (87% of patients taking > 10 medications), and a heavy comorbidity burden (85% hypertension, 80% dyslipidemia, 59% diabetes mellitus type II) from January to October 2017. Pharmacists identified 344 medication discrepancies and 301 drug therapy problems, resulting in 398 changes in care process. The most frequently identified discrepancies and drug therapy problems were the omission of an active medication from the medication list (86 of 344 discrepancies, 25%) and potentially inappropriate medications (106 of 301 drug therapy problems, 35%). Pharmacists recommended 228 medication changes, provided 76 adherence devices, facilitated 24 consults or referrals, and communicated with the primary care team on 70 occasions. The interprofessional team members all strongly agreed that patients and the team benefited from the pharmacists' involvement.

CONCLUSION

Pharmacy resident-led medication reconciliation resulted in the identification and resolution of medication discrepancies and drug therapy problems, leading to changes in the care process.

Exploring instruments used to evaluate potentially inappropriate medication use in hospitalised elderly patients in Kosovo

OBJECTIVES

A number of instruments are used to identify potentially inappropriate medications (PIMs) in the elderly. In this study we identify PIMs in elderly patients and aim to compare three different instruments used to assess PIMs.

METHODS

In this prospective cohort study, we compared medications of elderly patients against three commonly used instruments: Beers' list, PRISCUS and STOPP/START, at the point of hospital admission and discharge in the nephrology clinic of Kosovo's largest hospital. Readmission risk was evaluated using the LACE Index and correlations with the number of PIMs and PIMs criteria were analysed.

RESULTS

Of 184 patients admitted to the nephrology clinic, 84 met study inclusion criteria. Patients had a median of three drugs at admission and four at discharge. Hospital readmission risk was high with median LACE Index being 11 (63% of patients). A higher number of PIMs was associated at the point of discharge compared with admission for all three tools (Beers' list: 29% vs 38 %, P=0.04; STOPP/STRART: 20% vs 23%, P<0.001; PRISCUS list: 12% vs 21%, P<0.001). The number of drugs at admission predicted the number of PIMs at discharge only when using Beers' criteria (P=0.006). At discharge, each increase in medication was associated with an increase in PIMs based on Beers' [0.134; (P=0.007)] and STOPP/START criteria [0.130; (P=0.005)]. Nitrofurantoin was the main PIM identified with Beers' and PRISCUS list in comparison to proton- pump-inhibitors being the most prevalent agents identified with STOPP/START criteria.

CONCLUSIONS

There are differences when using Beers' criteria, STOPP/START criteria and PRISCUS list during identification of PIMs in elderly patients with high readmission risk. These differences should be considered when identifying PIMs in hospital settings.

The Role of Deprescribing in Older Adults with Chronic Kidney Disease

Older adults with chronic kidney disease (CKD) often experience polypharmacy, a recognized predictor of prescribing problems including inappropriately dosed medications, drug-drug and drug-disease interactions, morbidity and mortality. Polypharmacy is also associated with nonadherence, which leads to recurrent hospitalizations and poorer hemodialysis outcomes in CKD patients. Further complicating medication management in this vulnerable population are the physiologic changes that occur with both age and CKD. This guide for pharmacists and prescribers offers considerations in medication evaluation and management among older adults with CKD. Careful prescribing with the aid of tools such as the American Geriatrics Society Beers Criteria can support safe medication use and appropriate prescribing. Polypharmacy may be systematically addressed through 'deprescribing,' an evidence-based process that enables identification and elimination of unnecessary or inappropriate medications. Detailed guidance for deprescribing in older adults with CKD has not been published previously. We highlight three specific targets for medication optimization and deprescribing in older adults with CKD: (1) proton pump inhibitors, (2) oral hypoglycemic agents, including newer classes of agents, and (3) statins. These medication classes have been chosen as they represent three of the most commonly prescribed classes of medications in the United States. For each area, we review considerations for medication use in older adults with CKD and provide strategies to avoid, modify, or discontinue these medications when clinically indicated. By utilizing deprescribing techniques, pharmacists are well positioned to help decrease the medication burden in older adults with CKD, thereby potentially reducing the risk of morbidity and mortality associated with polypharmacy.

A Study of the Use of Psychopharmacologic Agents by Acutely Medically Ill Older Adults

This retrospective study sought to investigate issues related to the safety of psychopharmacological agents used by acutely medically ill hospitalized older adults. It explored if there were any associations between commonly prescribed psychiatric medications that medically ill hospitalized older adults received and adverse events. It also sought to compare the safety of antidepressants, sedative/hypnotics, and antipsychotics, when used as a standing (on a preset schedule) and as needed pro re nata (PRN) basis. The study found that psychopharmacological agents are frequently prescribed for medically ill hospitalized older adults. No statistically significant difference was found as far as safety was concerned. The number of PRN medications that were used, and the total number of medications was associated with increased risk of transfer within the hospital to a higher level of care or transfer upon discharge to long-term-care/rehabilitation or hospice. Overall, the use of psychopharmacological agents did not appear to be related to serious adverse events.

Necessity of D2 lymph node dissection in older patients ≥80years with gastric cancer

OBJECTIVES

This study analyzed the effect of D2 lymph node (LN) dissection on complications and survival in older patients with gastric cancer.

MATERIALS AND METHODS

A total of 103 octogenarian patients who underwent curative gastrectomy for gastric cancer were divided into two groups (D2 and D1) according to the extent of LN dissection and analyzed retrospectively for complications and survival.

RESULTS

No differences were observed in short-term postoperative outcomes, including complication rates, between the two groups. In a survival analysis, D2 LN dissection did not improve overall survival (OS) in any patient, including advanced cases. A Cox regression analysis revealed that the independent risk factors for OS were history of coronary artery disease (hazard ratio [HR], 11.095), postoperative short-term complications (HR, 9.939), and TNM stage (HR, 6.299). The extent of LN dissection was not an independent risk factor for OS, and D2 or more LN dissection (odds ratio, 10.89) increased the risk independently.

CONCLUSIONS

D2 or more LN dissection did not improve survival, but rather increased the risk of complications. Thus, LN dissection should be performed sparingly in octogenarian patients with gastric cancer.

Dietary Supplement Use Was Very High among Older Adults in the United States in 2011-2014

Background: Dietary supplements (DSs) have the potential to be both beneficial and harmful to health, especially in adults aged ≥60 y, and therefore it is important to monitor the patterns of their use.Objective: This study evaluated DS use by adults aged ≥60 y to characterize the use of DSs, determine the motivations for use, and examine the associations between the use of DSs and selected demographic, lifestyle, and health characteristics.Methods: Data from 3469 older adults aged ≥60 y from the 2011-2014 NHANES were analyzed. DSs used in the past 30 d were ascertained via an interviewer-administered questionnaire in participants' homes. The prevalence of overall DS use and specific types of DSs were estimated. The number of DSs reported and the frequency, duration, and motivation(s) for use were assessed. Logistic regression models were constructed to examine the association between DS use and selected characteristics.Results: Seventy percent of older adults in the United States reported using ≥1 DS in the past 30 d; 54% of users took 1 or 2 products, and 29% reported taking ≥4 products. The most frequently reported products were multivitamin or mineral (MVM) (39%), vitamin D only (26%), and omega-3 fatty acids (22%). Women used DSs almost twice as often as men [adjusted OR (aOR), 1.8; 95% CI: 1.5, 2.3). Those not reporting prescription medications were less likely to take a DS than those reporting ≥3 prescription medications (aOR, 0.4; 95% CI: 0.3, 0.6). The most frequently reported motivation for DS use was to improve overall health (41%).Conclusions: Use of DSs among older adults continues to be high in the United States, with 29% of users regularly taking ≥4 DSs, and there is a high concurrent usage of them with prescription medications.
