Potentially preventable medication-related hospitalizations: A clinical pharmacist approach to assessment, categorization, and quality improvement

An Intervention Program to Reduce Medication-Related Problems Among Polymedicated Home-Dwelling Older Adults (OptiMed): Protocol for a Pre-Post, Multisite, Pilot, and Feasibility Study

BACKGROUND

Effective medication management is one of the essential preconditions for enabling polymedicated home-dwelling older adults with multiple chronic conditions to remain at home and preserve their quality of life and autonomy. Lack of effective medication management predisposes older adults to medication-related problems (MRPs) and adverse health outcomes, which can lead to the degradation of a patient's acute clinical condition, physical and cognitive decline, exacerbation of chronic medical conditions, and avoidable health care costs. Nonetheless, it has been shown that MRPs can be prevented or reduced by using well-coordinated, patient-centered, interprofessional primary care interventions.

OBJECTIVE

This study aimed to explore the feasibility and acceptability of an evidence-based, multicomponent, interprofessional intervention program supported by informal caregivers to decrease MRPs among polymedicated home-dwelling older adults with multiple chronic conditions.

METHODS

This quasi-experimental, pre-post, multisite pilot, and feasibility study will use an open-label design, with participants knowing the study's objectives and relevant information, and it will take place in primary health care settings in Portugal and Switzerland. The research population will comprise 30 polymedicated, home-dwelling adults, aged ≥65 years at risk of MRPs and receiving community-based health care, along with their informal caregivers and health care professionals.

RESULTS

Before a projected full-scale study, this pilot and feasibility study will focus on recruiting and ensuring the active collaboration of its participants and on the feasibility of expanding this evidence-based, multicomponent, interprofessional intervention program throughout both study regions. This study will also be essential to projected follow-up research programs on informal caregivers' multiple roles, enhancing their coordination tasks and their own needs. Results are expected at the end of 2024.

CONCLUSIONS

Designing, establishing, and exploring the feasibility and acceptability of an intervention program to reduce the risks of MRPs among home-dwelling older adults is an underinvestigated issue. Doing so in collaboration with all the different actors involved in that population's medication management and recording the first effects of the intervention will make this pilot and feasibility study's findings very valuable as home care becomes an ever more common solution.

Drug-Related Hospital Admissions and Associated Factors among Adults Admitted to Felege Hiwot Comprehensive and Specialized Hospital, North West Ethiopia

Background

A drug-related problem (DRP) is an event involving drug therapy that actually or potentially interferes with the desired therapeutic outcome. Drug-related hospital admission (DRHA) is hospitalization due to one or more DRPs.

Objective

This study was aimed at assessing the prevalence of DRHA and factors associated with it among adults admitted to the internal medicine wards of Felege Hiwot Comprehensive Specialized Hospital.

Methods

A prospective cross-sectional study was conducted using a previously validated tool, AT-HARM 10. Data were collected by two clinical pharmacists from July 1 to September 15, 2020. The data were entered into EpiData software (version 4.2.0.0) and then transported to Statistical Package for Social Sciences (SPSS®) software (version 24) (IBM Corporation) for analysis. Descriptive statistics were presented using frequency and proportion. Binary logistic regression was applied to identify factors associated with DRHAs with a 95% confidence level, and significance was declared at a p value <0.05.

Results

The prevalence of DRHAs was 31.9% (95% CI = 27.7%–36.4%). From this, noncompliance (37.8%) (95% CI = 29.6–45.9), untreated indication (31.9%) (95% CI = 23.7–40), and adverse drug reaction (15.6%) (95% CI = 9.6–21.5) cause the majority of DRHAs. More than a quarter (28.8%) of all admissions were preventable. Most DRHAs were moderate (76.3) and preventable (80.7%). Lower to medium Charlson comorbidity index scores, longer duration of therapy, and not having health insurance were significantly associated with DRHAs.

Conclusion

The prevalence of DRHAs was considerably high. Noncompliance, untreated indications, and adverse drug reactions were the commonest DRPs that caused DRHAs. Lower to medium Charlson comorbidity index scores, longer duration of therapy, and not having health insurance were significantly contributing factors of DRHAs. Therefore, all healthcare providers should prevent, identify, and resolve DRPs to decrease DRHAs in the hospital.

Prevalence and predictors of drug-related hospitalisation among patients visiting emergency departments of Addis Ababa city hospitals in Ethiopia: a multicentre prospective observational study

OBJECTIVES

This study aimed to determine the prevalence, categories and predictors of drug-related hospitalisation (DRH) among patients visiting emergency departments of Addis Ababa city hospitals, Ethiopia.

DESIGN

A multicentre prospective observational study was conducted through patients' interview and chart review.

SETTINGS

The study was undertaken in three tertiary care hospitals in Addis Ababa, Ethiopia.

PARTICIPANTS

A total of 423 patients fulfilling the inclusion criteria were included.

OUTCOME MEASURES

Prevalence and preventability of DRH, categories of drug-related problems causing DRH, medications and diseases involved in DRH, and factors significantly associated with DRH.

RESULT

More than half of the patients (216, 51.1%) were female. The mean age (SD) was 47.50 (±17.21) years. The mean length of hospital stay (SD) was 10.29 (±8.99) days. Nearly 60% (249) of them were hospitalised due to drug-related problems, of which 87.8% were preventable. The cause for hospitalisation for more than half (130, 53%) of them was a failure to receive drugs, and 37.85 (94) patients were categorised as untreated indications. Age ≥65 years (adjusted OR (AOR)=7.451, 95% CI: 1.889 to 29.397), tertiary educational level (AOR=0.360, 95% CI: 0.141 to 0.923), participants who did not have any occupation (AOR=3.409, 95% CI: 1.120 to 10.374) and presence of comorbid conditions (AOR=2.004, 95% CI: 1.095 to 3.668) were predictors of DRH.

CONCLUSION

Nearly 90% of DRH was deemed to be preventable in the study settings. Older age, lower educational level, unemployment and presence of comorbid conditions in hospital as an inpatient were predictors of DRH.

Assessing the impact of adding pharmacist management services to an existing discharge planning program on 30-day readmissions

BACKGROUND

Although hospital readmission rates are declining nationally, avoidable readmissions remain a public health concern. Effective readmission interventions are multifaceted and include discharge planning and transition-of-care coordination. Clinical pharmacists are effective contributors to these processes, bringing expertise to discharge counseling, medication reconciliation, medication adherence, and postdischarge follow-up counseling.

OBJECTIVE

We evaluated the impact of adding health plan clinical pharmacy management services to an existing discharge program on all-cause readmissions and postdischarge primary physician visits.

METHOD

Pharmacy management services by health plan clinical pharmacists of a large regional integrated delivery system were added to an existing optimal discharge planning (ODP) program. Criteria for eligibility for these pharmacists' services included patients who prescribed a new maintenance medication after discharge, received a therapeutic substitution, had a previous discharge within 30 days, or were taking a high-risk medication. A retrospective, observational analysis of a subgroup of patients, who received the pharmacy management services as part of ODP, was performed using a difference-in-difference model, by comparing propensity-matched discharges from February 22, 2016, to January 31, 2017 (preprogram implementation) with discharges from February 22, 2017, to January 31, 2018 (implementation period), to estimate changes in 30-day readmission rates and postdischarge primary physician visits.

RESULTS

A total of 111 of the propensity matched received the pharmacy management services; of these, 73% (ODP) versus 64% (non-ODP) were ≥ 58 years, 60% were females, and 62% (ODP) versus 52% (non-ODP) were Medicare beneficiaries. There was a 16.7% (P = 0.022) statistically significant reduction in combined inpatient and observation 30-day readmissions and a 19.7% increase in 5-day postdischarge follow-up physician visits (P = 0.037) for the subgroup who also received the pharmacy management services.

CONCLUSION

Addition of pharmacist management services to an existing hospital discharge program for select at-risk patients was associated with reduced inpatient and observation 30-day readmissions.

Development of a New Patient-Reported Medication Adherence Instrument: Concerns Influencing Medication Adherence

PURPOSE

The purpose of this research was to conceptualize and develop a tool for identifying persons who are, or are likely to be, non-adherent to medications prescribed by their healthcare provider(s) by identifying concerns that patients have regarding their treatments.

PATIENTS AND METHODS

The target populations were persons diagnosed with atrial fibrillation or osteoarthritis, who were prescribed anticoagulants or over-the-counter or prescription pain medications, respectively. In this two-stage, multi-year, qualitative research study, relevant concepts were explored, confirmed and refined. The focus was on non-adherence due to active (thus potentially modifiable) patient decisions to forego taking medications as prescribed.

RESULTS

The most common concerns among participants with atrial fibrillation were medication-related side effects and fear of bleeding. Participants with osteoarthritis were most concerned about short-term stomach problems and long-term kidney and liver side effects. The Concerns Influencing Medication Adherence (CIMA) instrument was developed based on these concerns and those identified in the literature. It is comprised of 16 items: a core set of 11 items potentially applicable to multiple disease states, 3 items specific to atrial fibrillation, and 2 items unique to osteoarthritis. The instrument is intended to be completed electronically, and publicly available for use in direct patient care in the United States or in population health management.

CONCLUSION

To our knowledge, this is the first instrument focused on medication adherence that includes documented details of patient input as recommended by the United States Food and Drug Administration guidance. Patient input is considered a key component of content validity. In this research, for example, the concerns that patients have regarding their treatments can be expected to have affected past medication adherence and can potentially impact future adherence. Although applicability outside atrial fibrillation or osteoarthritis was not assessed, the general items may be useful in assessing adherence in other chronic diseases.

Risk of 30-day hospital readmission associated with medical conditions and drug regimens of polymedicated, older inpatients discharged home: a registry-based cohort study

OBJECTIVES

The present study analysed 4 years of a hospital register (2015-2018) to determine the risk of 30-day hospital readmission associated with the medical conditions and drug regimens of polymedicated, older inpatients discharged home.

DESIGN

Registry-based cohort study.

SETTING

Valais Hospital-a public general hospital centre in the French-speaking part of Switzerland.

PARTICIPANTS

We explored the electronic records of 20 422 inpatient stays by polymedicated, home-dwelling older adults held in the hospital's patient register. We identified 13 802 hospital readmissions involving 8878 separate patients over 64 years old.

OUTCOME MEASURES

Sociodemographic characteristics, medical conditions and drug regimen data associated with risk of readmission within 30 days of discharge.

RESULTS

The overall 30-day hospital readmission rate was 7.8%. Adjusted multivariate analyses revealed increased risk of hospital readmission for patients with longer hospital length of stay (OR=1.014 per additional day; 95% CI 1.006 to 1.021), impaired mobility (OR=1.218; 95% CI 1.039 to 1.427), multimorbidity (OR=1.419 per additional International Classification of Diseases, 10th Revision condition; 95% CI 1.282 to 1.572), tumorous disease (OR=2.538; 95% CI 2.089 to 3.082), polypharmacy (OR=1.043 per additional drug prescribed; 95% CI 1.028 to 1.058), and certain specific drugs, including antiemetics and antinauseants (OR=3.216 per additional drug unit taken; 95% CI 1.842 to 5.617), antihypertensives (OR=1.771; 95% CI 1.287 to 2.438), drugs for functional gastrointestinal disorders (OR=1.424; 95% CI 1.166 to 1.739), systemic hormonal preparations (OR=1.207; 95% CI 1.052 to 1.385) and vitamins (OR=1.201; 95% CI 1.049 to 1.374), as well as concurrent use of beta-blocking agents and drugs for acid-related disorders (OR=1.367; 95% CI 1.046 to 1.788).

CONCLUSIONS

Thirty-day hospital readmission risk was associated with longer hospital length of stay, health disorders, polypharmacy and drug regimens. The drug regimen patterns increasing the risk of hospital readmission were very heterogeneous. Further research is needed to explore hospital readmissions caused solely by specific drugs and drug-drug interactions.

Predictors of Medication-Related Emergency Department Admissions Among Patients with Cardiovascular Diseases at Mbarara Regional Referral Hospital, South-Western Uganda

BACKGROUND

Medication-related emergency department admissions impose a huge and unnecessary burden on the healthcare system. We sought to determine the prevalence and predictors of medication-related emergency department admissions, among patients with cardiovascular diseases at Mbarara Regional Referral Hospital, Uganda.

METHODS

Institutional research ethics approval was secured to conduct a cross-sectional study at the Mbarara Regional Referral Hospital emergency department, between February and September, 2020. All eligible and consenting patients were enrolled in a consecutive manner after a preliminary diagnosis was made by the attending physician. Structured questionnaire interview and comprehensive medication history reviews were used to identify medication therapy problems, in collaboration with a resident physician present on duty. We used sequential categorization for medication therapy problem(s). Descriptive and logistic regression analyses were used to determine prevalence and predictors of medication-related emergency department admissions.

RESULTS

Out of the 128 patients interviewed, 105 (82%) patient admissions were associated with a medication therapy problem: ineffectiveness of drug therapy (53.3%, 56), medication non-adherence (42.9%, 45), and adverse drug reactions (3.8%, 4). Out of a total of 90 incidences of medication non-adherence, 34.4% (31/90) were due to lack of understanding of patient medication regimen, and 27.8% (25/90) due to unaffordable cost of medicines. Female gender (AOR = 4.31 [1.43, 13.03 at 95% CI]; P-value = 0.010]) and a history of tobacco use (AOR = 9.58 [1.14, 80.28 at 95% CI]; P-value = 0.037) were statistically significant predictors of medication-related emergency department admissions in adjusted analysis.

CONCLUSION

Four in five emergency department admissions were associated with medication-related causes, majorly due to ineffectiveness of drug therapy. Knowledge gap on patient medication regimens was the most prevalent cause for medication non-adherence. Female gender and previous or current tobacco use was an independent risk factor for medication-related admissions.

Impact of Adding Pharmacists and Comprehensive Medication Management to a Medical Group's Transition of Care Services

OBJECTIVES

Evaluate the impact of pharmacist-provided transition of care (TOC) services on hospital readmissions.

METHODS

Starting March 2014, TOC services were provided to all hospitalized patients from an at-risk medical group. Data covering all inpatient and outpatient services and prescription drugs were retrieved for all adult patients discharged between January 2010 and December 2018. The overall impact of TOC was estimated using a generalized estimating equation with logistic regression. Longitudinal TOC effects were estimated using generalized estimating equation in an interrupted time series model. Parallel analyses were conducted using data from an affiliated medical group in a neighboring county without access to the TOC intervention.

RESULTS

The study included 13,256 hospital discharges for adult patients for the 30-day readmission analysis and 10,740 discharges for the 180 days analysis. The TOC program reduced 30-day readmission risk by 34.9% [odds ratio (OR)=0.651 (range, 0.590-0.719)] and 180-day readmissions by 33.4% [OR=0.666 (range, 0.604-0.735)]. The interrupted time series results found the 30-day readmission rate to be stable over the pre-TOC period (OR=0.00; not significant) then to decreased by 1.5% per month in the post-TOC period [OR=0.985 (range, 0.980-0.991)]. For 180-day readmissions, risk decreased by 1% per month after TOC implementation [OR=0.990 (range, 0.984-0.996)]. Referral to the medical group's pre-existing Priority Care clinic also reduced readmission risk. Results from the comparison medical group found 180-day readmission declined by 1% per month after March 2014 [OR=0.990 (0.891-1.00)].

CONCLUSIONS

Adding a pharmacist-led TOC program to the medical group's existing outpatient services reduced 30- and 180-day readmissions by "bending the curve" for readmission risk over time.

A comparison of medication access services at 340B and non-340B hospitals

BACKGROUND

For patients that face barriers to filling their prescriptions, the availability of medication access services at their site of care can mean the difference between receiving prescribed drug therapy, and undue interruptions in care. Hospitals often provide medication access services that are not reimbursed by payers; however, they can be challenging to sustain. The 340B Drug Pricing Program allows covered entities to generate savings through discounted pricing for certain outpatient medications, which can then be used to provide more comprehensive services, including medication access services.

OBJECTIVE

To characterize medication access services provided at hospitals that participate in the 340B Drug Pricing Program compared to hospitals that do not participate in the 340B Program.

METHODS

Primary questionnaire response data was collected from a national sample of Directors of Pharmacy at non-federal acute care hospitals from March 2019 to May 2019. American Hospital Association Data Viewer was used to collect demographic information on 1,531 hospitals. Hospitals were excluded if they had 199 beds or fewer, did not have a unique Medicare provider ID, were federally owned, were located outside the continental U.S., or were non-acute care hospitals that served niche patient populations. This study utilized a proportional stratified sampling strategy to administer an electronic questionnaire to 340B and non-340B hospitals to assess the number and type of medication access service offerings. A final randomized sample of 500 hospitals were administered the questionnaire, and data was collected through recorded responses in Qualtrics software.

RESULTS

340B hospitals provided a significantly higher average number of medication access services compared to non-340B hospitals (6.20 vs. 3.91, p = 0.0001), adjusted for differences in hospital size and ownership type. For all nine medication access services that were assessed, a higher percentage of 340B hospitals reported providing the service compared to non-340B hospitals. This difference was statistically significant for six out of nine programs assessed.

CONCLUSIONS

340B hospitals provided more medication access services, on average, than comparably sized non-340B hospitals, suggesting that hospitals participating in the 340B Drug Pricing Program may be better positioned to create and administer programs that support medication access services.

Informing the development of a transitions of care program between an emergency department and regional supermarket chain pharmacies

OBJECTIVES

Pharmacist collaboration in transitions of care (TOC) programs is integral to increase patient education and adherence after discharge. This study aimed to conduct a qualitative evaluation of stakeholder perspectives to inform the design and implementation of a TOC program between an emergency department (ED) and regional supermarket chain pharmacies.

METHODS

Pharmacies from a regional supermarket chain were identified for inclusion on the basis of geographic proximity to a local community hospital ED. Semistructured, one-on-one interviews with the primary investigator were conducted. Interview questions were based on the Consolidation Framework for Implementation Research (CFIR). The following 5 CFIR domains were used: (1) intervention characteristics, (2) outer setting, (3) inner setting, (4) characteristics of individuals, and (5) process. Interviews were audio-recorded and transcribed. Two investigators coded each transcript independently. A thematic analysis was performed.

RESULTS

A total of 19 interviews were conducted, and the following 7 major themes emerged on analysis: (1) enhance real-time interprofessional communication, (2) establish data sharing between the ED and the community pharmacy, (3) provide timely resolution of prescription insurance issues for new therapies post-ED discharge, (4) use off-site pharmacy resources to support community pharmacy workflow, (5) increase patient education to prevent primary medication nonadherence, (6) reinforce discharge care plans, and (7) focus on community-dwelling older adult patients in an ED care transition program.

CONCLUSION

Health care providers including pharmacists, physicians, nurses, and care managers, view an ED-to-community pharmacy TOC program as a valuable service to increase patient education on new medications and discharge planning. Establishment of data sharing and reimbursement is integral to the development, implementation, and sustainability of such programs. There is an untapped opportunity for community pharmacists to bridge the gap in care after ED discharge.

Pharmacists' Knowledge and Practice of Issues Related to Using Psychotropic Medication in Elderly People in Ethiopia: A Prospective Cross-Sectional Study

Purpose

This study is aimed at assessing pharmacists' knowledge and practice of issue related to usage of psychotropic medications in elderly people, in Gondar town Northwest, Ethiopia.

Methods

A cross-sectional study was conducted among pharmacists working in community, health center, and hospital pharmacies in Gondar town from March 1 to May 30, 2020. A total of 73 medication retail outlets (40 pharmacies and 33 drug stores) were included in this study. Pharmacy personnel's knowledge and practice were assessed using self-administered validated questionnaires. Binary and multivariable logistic regression analyses were used to assess the association between different variables. P < 0.05 was used to declare the association.

Result

A total of 144 pharmacists were included in the study; the mean age was 30.13 (SD ±5.87), ranging from 20 to 55years. The mean knowledge score was 7.789 (SD ±2.98), and 75 (52.1%) of them had poor knowledge. The mean practice score was 2.32 ± 0.912 (mean ± SD), and 77 (53.5%) of the respondents had poor practice. All participants had not taken on-the-job training about psychotropic medication. Work experience (P < 0.029) and personal monthly income (P < 0.046) were significantly associated with pharmacists' knowledge. There was a significant association between work experience and practice level (P < 0.043).

Conclusion

The knowledge and practice of pharmacy personnel were low for issues related to the use of psychotropic medication in the elderly. This result indicates the need for training for pharmacists on pharmacotherapy of psychotropic medication.

A multicenter quality improvement initiative on the impact of pharmacists' postdischarge follow-up to reduce medication-related acute care episodes

PURPOSE

This multicenter quality improvement initiative aims to measure and quantify pharmacists' impact on reducing medication-related acute care episodes (MACEs) for high-risk patients at an increased risk for readmission due to drug-related problems (DRPs).

METHODS

This was a prospective, multicenter quality improvement initiative conducted at 9 academic medical centers. Each participant implemented a standardized methodology for evaluating MACE likelihood to demonstrate the impact of pharmacist postdischarge follow-up (PDFU). The primary outcome was MACEs prevented, and the secondary outcome was DRPs identified and resolved by pharmacists. During PDFU, pharmacists were responsible for identification and resolution of DRPs, and cases were reviewed by physicians to confirm whether potential MACEs were prevented.

RESULTS

A total of 840 patients were contacted by 9 participating academic medical centers during a 6-week data collection period. Of these, 328 cases were identified as MACEs prevented during PDFU by pharmacists, and physician reviewers confirmed that pharmacist identification of DRPs during PDFU prevented 27.9% of readmissions. Pharmacist identified 959 DRPs, 2.8% (27) of which were identified as potentially life threatening. Potentially serious or significant DRPs made up 56.6% (543) of the DRPs, and 40.6% (389) were identified as having a low capacity for harm.

CONCLUSION

The results demonstrate that PDFU of high-risk patients reduces DRPs and prevents MACEs based on physician confirmation. Implementation of MACE methodology provides health-system pharmacy departments the ability to demonstrate pharmacists' value in transitions of care and assist in expanding pharmacist services.

Rates and Types of Medication-Related Problems in Patients Rehospitalized Within 30 Days of Discharge From a Community Hospital

Background: Impact of medication-related problems (MRPs) on persistently high hospital readmission rates are not well described. Objective: The purpose of this study was to determine the rate and type of MRPs attributed to rehospitalization within 30 days of discharge from a general internal medicine hospitalists' service at a nonacademic medical center. Methods: A retrospective cohort study was conducted evaluating consecutive patients readmitted within 30-days after discharge to home from an internal medicine hospitalist service. Readmissions attributed to MRPs in physician documentation were systematically classified as indication, effectiveness, adverse drug reaction, or nonadherence problems and evaluated for possible preventability. Descriptive statistics were used to describe the rate and type of MRP. Results: Evaluation of consecutive 30-day readmissions (n = 203) to a nonteaching community hospital identified 50.2% of admissions attributed to MRPs. MRPs (n = 102) were categorized as problems of indication (34.3%), efficacy (19.6%), adverse drug events (18.6%), and nonadherence (27.5%). One third of 30-day readmissions in this cohort were attributed to potentially preventable MRPs. Conclusion: MRPs are frequently implicated in 30-day hospital readmissions in a nonteaching community hospital representing an opportunity for context-specific improvements.

Polypharmacy Among Home-Dwelling Older Adults: The Urgent Need for an Evidence-Based Medication Management Model

Ageing populations with multiple chronic conditions challenge low-, middle-, and high-income countries. Older adults frequently depend on complex medication regimens and polypharmacy, both of which can lead to potentially devastating and debilitating medication-related problems and to subsequent far-reaching public health, social, and economic effects. This perspectives article provides an overview of the current state of medication management, reflects on its relevance among polymedicated home-dwelling older adults living with multiple chronic conditions, and proposes patient-centered approaches for optimizing medication management and preventing medication-related problems.

Optimising medication management for polymedicated home-dwelling older adults with multiple chronic conditions: a mixed-methods study protocol

INTRODUCTION

Optimal medication management is one of the basic conditions necessary for home-dwelling older adults living with multiple chronic conditions (OAMCC) to be able to remain at home and preserve their quality of life. Currently, the reasons for such high numbers of emergency department visits and the very significant rate of hospitalisations for OAMCC, due to medication-related problems (MRPs), is poorly explored. This study aims to reveal the current state of the medication management practices of polymedicated, home-dwelling OAMCC and to make proposals for improving clinical and medication pathways through an innovative and integrated model for supporting medication management and preventing adverse health outcomes.

METHODS AND ANALYSIS

A mixed-methods study will address the medication management of polymedicated, home-dwelling OAMCC. Its explanatory sequential design will involve two major phases conducted sequentially over time. The quantitative phase will consist of retrospectively exploiting the last 5 years of electronic patient records from a local hospital (N ≈ 50 000) in order to identify the different profiles-made up of patient-related, medication-related and environment-related factors-of the polymedicated, home-dwelling OAMCC at risk of hospitalisation, emergency department visits, hospital readmission (notably for MRPs), institutionalisation or early death. The qualitative study will involve: (a) obtaining and understanding the medication management practices and experiences of the identified profiles extracted from the hospital data of OAMCC who will be interviewed at home (N ≈ 30); (b) collecting and analysing the perspectives of the formal and informal caregivers involved in medication management at home in order to cross-reference perspectives about this important dimension of care at home. Finally, the mixed-methods findings will enable the development of an innovative, integrated model of medication management based on the Agency for Clinical Innovation framework and Bodenheimer and Sinsky's quadruple aim.

ETHICS AND DISSEMINATION

Ethical approval has been obtained from the Human Research Ethics Committee of the Canton Vaud (2018-02196). Findings will be disseminated in peer-reviewed journals, professional conferences and other knowledge transfer activities with primary healthcare providers, hospital care units, informal caregivers' and patients' associations.

Community-acquired and hospital-acquired medication harm among older inpatients and impact of a state-wide medication management intervention

Background

We previously reported reduction in the rate of hospitalisations with medication harm among older adults with our ‘Pharm2Pharm’ intervention, a pharmacist-led care transition and care coordination model focused on best practices in medication management. The objectives of the current study are to determine the extent to which medication harm among older inpatients is ‘community acquired’ versus ‘hospital acquired’ and to assess the effectiveness of the Pharm2Pharm model with each type.

Methods

After a 3-year baseline, six non-federal general acute care hospitals with 50 or more beds in Hawaii implemented Pharm2Pharm sequentially. The other five such hospitals served as the comparison group. We measured frequencies and quarterly rates of admissions among those aged 65 and older with ‘community-acquired’ (International Classification of Diseases-coded as present on admission) and ‘hospital-acquired’ (coded as not present on admission) medication harm per 1000 admissions from 2010 to 2014.

Results

There were 189 078 total admissions from 2010 through 2014, 7% of which had one or more medication harm codes. There were 16 225 medication harm codes, 70% of which were community-acquired, among these 13 795 admissions. The varied times when the intervention was implemented across hospitals were associated with a significant reduction in the rate of admissions with community-acquired medication harm compared with non-intervention hospitals (p=0.001), and specifically harm by anticoagulants (p<0.0001) and by medications in therapeutic use (p<0.001). The hospital-acquired medication harm rate did not change. The rate of admissions with community-acquired medication harm was reduced by 4.28 admissions per 1000 admissions per quarter in the Pharm2Pharm hospitals relative to the comparison hospitals.

Conclusion

The Pharm2Pharm model is an effective way to address the growing problem of community-acquired medication harm among high-risk, chronically ill patients. This model demonstrates the importance of deploying specially trained pharmacists in the hospital and in the community to systematically identify and resolve drug therapy problems.

A Statewide Medication Management System: Health Information Exchange to Support Drug Therapy Optimization by Pharmacists across the Continuum of Care

Background  While evidence generally supports the use of medication management technology, systems are typically implemented and evaluated piecemeal rather than as part of a comprehensive model for medication management. Systems to support drug therapy optimization, increasingly a key role of pharmacists in our healthcare system, have not yet been reported.

Objective  Our objective is to describe the design, implementation, and use of health information technology to support the hospital and community pharmacists' management of medications for high-risk patients statewide in the “Pharm2Pharm” model of care. Our aims were to make it easier for the pharmacists to access information needed to identify and resolve drug therapy problems using best practices for medication management and communicate with other members of the care team.

Methods  The pharmacist's roles and the medication management processes guided the design of the supporting technology, which was implemented after the Pharm2Pharm model was launched and the pharmacists' technology needs were assessed. Priorities for technology included sending care transition documents from hospital to community pharmacist securely and efficiently, access to medical records, including medications and laboratory results, documentation, and patient tracking. Implementation and use of the technology were documented.

Results  Communications, medication management, and population management solutions were implemented to support the Pharm2Pharm model. The pharmacists delivering services through this model adopted and meaningfully used this technology to support their work.

Conclusion  Implementing technology with value outside of the Pharm2Pharm model was a strategic approach to investment. This work emphasizes the importance of shifting the focus of technology from supporting a specific piece of the medication management process to supporting the goal of optimizing medication regimens. Health information exchange systems can provide important technology needed to integrate pharmacists into care teams as they are deployed to improve patient outcomes.
