How external and agency characteristics are related to coordination in homecare - findings of the national multicenter, cross-sectional SPOTnat study

BACKGROUND

Homecare client services are often distributed across several interdependent healthcare providers, making proper care coordination essential. However, as studies exploring care coordination in the homecare setting are scarce, serious knowledge gaps exist regarding how various factors influence coordination in this care sector. To fill such gaps, this study's central aim was to explore how external factors (i.e., financial and regulatory mechanisms) and homecare agency characteristics (i.e., work environment, workforce, and client characteristics) are related to care coordination in homecare.

METHODS

This analysis was part of a national multicentre, cross-sectional study in the Swiss homecare setting that included a stratified random sample of 88 Swiss homecare agencies. Data were collected between January and September 2021 through agency and employee questionnaires. Using our newly developed care coordination framework, COORA, we modelled our variables to assess the relevant components of care coordination on the structural, process, and outcome levels. We conducted both descriptive and multilevel regression analyses-with the latter adjusting for dependencies within agencies-to explore which key factors are associated with coordination.

RESULTS

The final sample size consisted of 1450 employees of 71 homecare agencies. We found that one explicit coordination mechanism ("communication and information exchange" (beta = 0.10, p <.001)) and four implicit coordination mechanisms-"knowledge of the health system" (beta = -0.07, p <.01), "role clarity" (beta = 0.07, p <.001), "mutual respect and trust" (beta = 0.07, p <.001), and "accountability, predictability, common perspective" (beta = 0.19, p <.001)-were significantly positively associated with employee-perceived coordination. We also found that the effects of agency characteristics and external factors were mediated through coordination processes.

CONCLUSION

Implicit coordination mechanisms, which enable and enhance team communication, require closer examination. While developing strategies to strengthen implicit mechanisms, the involvement of the entire care team is vital to create structures (i.e., explicit mechanisms) that enable communication and information exchange. Appropriate coordination processes seem to mitigate the association between staffing and coordination. This suggests that they support coordination even when workload and overtime are higher.

Evaluation of Triple Whammy Prescriptions After the Implementation of a Drug Safety Algorithm

BACKGROUND AND OBJECTIVE

The term triple whammy (TW) refers to the concomitant use of non-steroidal anti-inflammatory drugs, diuretics, and angiotensin system inhibitors; this combination significantly increases the risk of acute kidney injury (AKI). To prevent this serious complication, we developed an electronic algorithm that detects TW prescriptions in patients with additional risk factors such as old age and impaired kidney function. The algorithm alerts a clinical pharmacist who then evaluates and forwards the alert to the prescribing physician.

METHODS

We evaluated the performance of this algorithm in a retrospective observational study of clinical data from all adult patients admitted to the Cantonal Hospital of Aarau in Switzerland in 2021. We identified all patients who received a TW prescription, had a TW alert, or developed AKI during TW therapy. Algorithm performance was evaluated by calculating the sensitivity and specificity as a primary endpoint and determining the acceptance rate among clinical pharmacists and physicians as a secondary endpoint.

RESULTS

Among 21,332 hospitalized patients, 290 patients had a TW prescription, of which 12 patients experienced AKI. Overall, 216 patients were detected by the alert algorithm, including 11 of 12 patients with AKI; the algorithm sensitivity is 88.3% with a specificity of 99.7%. Physician acceptance was high (77.7%), but clinical pharmacists were reluctant to forward the alerts to prescribers in some cases.

CONCLUSION

The TW algorithm is highly sensitive and specific in identifying patients with TW therapy at risk for AKI. The algorithm may help to prevent AKI in TW patients in the future.

Developing indicators for medication-related readmissions based on a Delphi consensus study

BACKGROUND

Medication-related readmissions challenge healthcare systems by burdening patients, increasing costs and straining resources. However, to date, there has been no consensus study on indicators for medication-related readmissions.

OBJECTIVES

This Delphi study aimed to develop a consensus-based set of indicators for detecting patients at risk of medication-related readmission.

METHODS

An expert panel of clinical pharmacists, physicians and nursing experts participated in a two-round Delphi study. In round 1, 31 indicators taken from the literature were rated for relevance on a scale from 1 to 9, with a median rating of 7 or higher suggesting relevance. The RAND/UCLA method was used to determine consensus. In round 2, indicators lacking consensus were re-rated together with a series of new indicators generated by the experts. Additional details were sought for some indicators. The main outcomes were the relevance of, consensus on, and completeness of the proposed indicators for identifying risks of 30-day medication-related readmission.

RESULTS

Thirty-eight experts participated in round 1. Consensus was found for all the indicators, with 25 included and 6 excluded. Thirty-four experts participated in round 2. Consensus was found for all 5 newly suggested indicators, and 4 were included. The expert panel prioritized the following indicators: (1) insufficient communication between different healthcare providers, (2) polypharmacy (≥7 medications), (3) low rates of medication adherence (twice-weekly mistakes or missing administration), (4) complex medication regimens (≥3 doses, ≥2 dosage forms and ≥2 administration routes per day), and (5) multimorbidity (≥3 chronic conditions). The final set comprised 29 indicators.

CONCLUSIONS

The indicator set developed for flagging potential medication-related readmissions could guide priorities for clinical pharmacy services at hospital discharge, improving patient outcomes and resource use. A validation study of these indicators is planned.

Development of a quality assessment tool for pharmacy and therapeutics committees and subsequent pilot testing

Pharmacy and therapeutics committees (PTCs) are multidisciplinary hospital teams responsible for rational medication use. We aimed at developing and piloting an assessment tool for their operating quality.We conducted a scoping literature review in PubMed and Embase to identify potential assessment items. Their relevance was systematically rated and consolidated into the final tool.60 relevant items were included, grouped into eight focus topics: the committee's institutional integration, member characteristics, performance indicators, meeting structure, formulary decision-making and characteristics, strategies to guide medication use and medication use evaluations.In combination with a SWOT (strengths, weaknesses, opportunities and threats) analysis, the tool helped the identification of improvement opportunities for a pilot hospital: adapting the committee's structure, improving the formulary decision-making, implementing strategies to guide formulary medication use and strengthening the committee's recognition within the institution.The tool successfully identified improvement opportunities for a PTC and could therefore be interesting for other hospitals.

Exploring medication safety structures and processes in nursing homes: a cross-sectional study

BACKGROUND

Medication safety is important to limit adverse events for nursing home residents. Several factors, such as interprofessional collaboration with pharmacists and medication reviews, have been shown in the literature to influence medication safety processes.

AIM

This study had three main objectives: (1) To assess how facility- and unit-level organization and infrastructure are related to medication use processes; (2) To determine the extent of medication safety-relevant processes; and (3) To explore pharmacies' and pharmacists' involvement in nursing homes' medication-related processes.

METHOD

Cross-sectional multicenter survey data (2018-2019) from a convenience sample of 118 Swiss nursing homes were used. Data were collected on facility and unit characteristics, pharmacy services, as well as medication safety-related structures and processes. Descriptive statistics were used.

RESULTS

Most of the participating nursing homes (93.2%) had electronic resident health record systems that supported medication safety in various ways (e.g., medication lists, interaction checks). Electronic data exchanges with outside partners such as pharmacies or physicians were available for fewer than half (10.2-46.3%, depending on the partner). Pharmacists collaborating with nursing homes were mainly involved in logistical support. Medication reviews were reportedly conducted regularly in two-thirds of facilities.

CONCLUSION

A high proportion of Swiss nursing homes have implemented diverse processes and structures that support medication use and safety for residents; however, their collaboration with pharmacists remains relatively limited.

Risk factors for medication-related short-term readmissions in adults - a scoping review

BACKGROUND

Hospital readmissions due to medication-related problems occur frequently, burdening patients and caregivers emotionally and straining health care systems economically. In times of limited health care resources, interventions to mitigate the risk of medication-related readmissions should be prioritized to patients most likely to benefit. Focusing on general internal medicine patients, this scoping review aims to identify risk factors associated with drug-related 30-day hospital readmissions.

METHODS

We began by searching the Medline, Embase, and CINAHL databases from their inception dates to May 17, 2022 for studies reporting risk factors for 30-day drug-related readmissions. We included all peer-reviewed studies, while excluding literature reviews, conference abstracts, proceeding papers, editorials, and expert opinions. We also conducted backward citation searches of the included articles. Within the final sample, we analyzed the types and frequencies of risk factors mentioned.

RESULTS

After deduplication of the initial search results, 1159 titles and abstracts were screened for full-text adjudication. We read 101 full articles, of which we included 37. Thirteen more were collected via backward citation searches, resulting in a final sample of 50 articles. We identified five risk factor categories: (1) patient characteristics, (2) medication groups, (3) medication therapy problems, (4) adverse drug reactions, and (5) readmission diagnoses. The most commonly mentioned risk factors were polypharmacy, prescribing problems-especially underprescribing and suboptimal drug selection-and adherence issues. Medication groups associated with the highest risk of 30-day readmissions (mostly following adverse drug reactions) were antithrombotic agents, insulin, opioid analgesics, and diuretics. Preventable medication-related readmissions most often reflected prescribing problems and/or adherence issues.

CONCLUSIONS

This study's findings will help care teams prioritize patients for interventions to reduce medication-related hospital readmissions, which should increase patient safety. Further research is needed to analyze surrogate social parameters for the most common drug-related factors and their predictive value regarding medication-related readmissions.

Development of a patient-centred medication management model for polymedicated home-dwelling older adults after hospital discharge: results of a mixed methods study

OBJECTIVE

This study aimed to investigate medication management among polymedicated, home-dwelling older adults after discharge from a hospital centre in French-speaking Switzerland and then develop a model to optimise medication management and prevent adverse health outcomes associated with medication-related problems (MRPs).

DESIGN

Explanatory, sequential, mixed methods study based on detailed quantitative and qualitative findings reported previously.

SETTING

Hospital and community healthcare in the French-speaking part of Switzerland.

PARTICIPANTS

The quantitative strand retrospectively examined 3 years of hospital electronic patient records (n=53 690 hospitalisations of inpatients aged 65 years or older) to identify the different profiles of those at risk of 30-day hospital readmission and unplanned nursing home admission. The qualitative strand explored the perspectives of older adults (n=28), their informal caregivers (n=17) and healthcare professionals (n=13) on medication management after hospital discharge.

RESULTS

Quantitative results from older adults' profiles, affected by similar patient-related, medication-related and environment-related factors, were enhanced and supported by qualitative findings. The combined findings enabled us to design an interprofessional, collaborative medication management model to prevent MRPs among home-dwelling older adults after hospital discharge. The model comprised four interactive fields of action: listening to polymedicated home-dwelling older adults and their informal caregivers; involving older adults and their informal caregivers in shared, medication-related decision-making; empowering older adults and their informal caregivers for safe medication self-management; optimising collaborative medication management practices.

CONCLUSION

By linking the retrospective and prospective findings from our explanatory sequential study involving multiple stakeholders' perspectives, we created a deeper comprehension of the complexities and challenges of safe medication management among polymedicated, home-dwelling older adults after their discharge from hospital. We subsequently designed an innovative, collaborative, patient-centred model for optimising medication management and preventing MRPs in this population.

Care coordination in homecare and its relationship with quality of care: A national multicenter cross-sectional study

INTRODUCTION

As health care complexity increases, skilled care coordination is becoming increasingly necessary. This is especially true in homecare settings, where services tend to be highly interprofessional. Poor coordination can result in services being provided twice, at the wrong time, unnecessarily or not at all. In addition to risking harm to the client, such confusion leads to unnecessary costs. From the patient's perspective, then, professional coordination should help both to remove barriers limiting quality of care and to minimize costs. To date, though, studies examining the relationship between care coordination and care quality have faced multiple challenges, leading to mixed results. And in homecare contexts, where the clients are highly vulnerable and diverse care interfaces make coordination especially challenging, such studies are rare.

OBJECTIVES

Therefore, the aim of this study was to explore the relationship, from the perspectives of clients and of homecare professionals, between coordination and quality of care. For both groups, we hypothesized that better coordination would correlate with higher ratings of quality of care. For the clients, we predicted that higher coordination ratings would lead to lower incidence of unplanned health care use, i.e., emergency department (ED) visits, unscheduled urgent medical visits and hospitalizations.

DESIGN AND METHODS

This study is part of a national multi-center cross-sectional study in the Swiss homecare setting. We recruited 88 homecare agencies and collected data between January and September 2021 through written questionnaires for agencies' managers, employees (n = 3223) and clients (n = 1509). To test our hypotheses, we conducted multilevel analyses.

RESULTS

Employee-perceived care coordination ratings correlated positively with employee-rated quality of care (OR = 2.78, p < .001); client-perceived care coordination problems correlated inversely with client-reported quality of care (β = -0.55, p < .001). Client-perceived coordination problems also correlated positively with hospitalizations (IRR = 1.20, p < .05) and unscheduled urgent medical visits (IRR = 1.18, p < .05), but not significantly with ED visits. No associations were discernible between employee-perceived coordination quality and either health care service use or client quality-of-care ratings.

DISCUSSION

While results indicate relationships between coordination and diverse aspects of care quality, various coordination gaps (e.g., poor information flow) also became apparent. The measurement of both care coordination and quality of care remains a challenge. Further research should focus on developing and validating a coordination questionnaire that measures care coordination.

Counselling for Chronic Insomnia in Swiss Pharmacies: A Survey Study Based on Case Vignettes

(1) Introduction: Chronic insomnia (CI) reduces quality of life and may trigger depression and cardiovascular diseases. The European Sleep Research Society recommends cognitive behavioural therapy (CBT-I) as the first-line treatment. Because a recent study in Switzerland demonstrated that this recommendation was inconsistently followed by primary care physicians, we hypothesised that pharmacists also deviate from these guidelines. The aim of this study is to describe current treatment practices for CI recommended by pharmacists in Switzerland, compare them to guidelines and examine their attitudes towards CBT-I. (2) Methods: A structured survey was sent to all the members of the Swiss Pharmacists Association, containing three clinical vignettes describing typical CI pharmacy clients. Treatments had to be prioritised. The prevalence of CI, and the pharmacists' knowledge and interest in CBT-I were assessed. (3) Results: Of 1523 pharmacies, 123 pharmacists (8%) completed the survey. Despite large variations, valerian (96%), relaxation therapy (94%) and other phytotherapies (85%) were most recommended. Although most pharmacists did not know about CBT-I (72%) and only 10% had recommended it, most were very interested (64%) in education. Missing financial compensation hampers the recommendation of CBT-I. (4) Conclusions: Contrary to existing European guidelines, community pharmacists in Switzerland mostly recommended valerian, relaxation therapy and other phytotherapies for treating CI. This might be connected to the client's expectation of pharmacy services, e.g., medication dispensing. While pharmacists recommend sleep hygiene regularly, most did not know of CBT-I as an overarching concept but were willing to learn. Future studies should test the effects of dedicated training about CI and changes in the financial compensation for counselling for CI in pharmacies.

Clarifying the muddy concept of home healthcare coordination: A comprehensive theoretical framework

Effective healthcare coordination is vital when such care is provided as a collaborative effort by many individuals and their task activities are interdependent. Coordination is necessary to ensure that care not only meets the needs of patients, but also avoids negative consequences for them due to omitted, inefficient, unnecessary, or even incorrect treatments. It also helps conserve resources. This has contributed to a rapid increase in articles on this subject. Still, while care coordination topics are gaining the attention of researchers, there are a number of issues experienced, including the delineation of limitations, inconsistent definitions, and problems with measurement. Therefore, the aim of this article is to refine the concept of homecare coordination and provide a comprehensive theoretical framework, illustrated with examples from practice. Focusing on this goal, we have reviewed the extant literature on the subject to develop a theoretical homecare coordination framework. The first intermediary goal was to integrate relevant concepts across multiple theories and frameworks into a unified synthesis. We do so in two parts: (1) analysis of extant coordination frameworks and theories; and (2) the presentation of our newly developed theoretical framework for homecare coordination. The new framework differentiates clearly between coordination as a process-i.e., what people do to coordinate and coordination as an outcome-i.e., the state of coordination. Applying this distinction to both, measurement and interpretation of results helps avoid misleading conclusions. As a research outcome, our framework builds upon the extant coordination literature, considers the complex relationships among the various coordination-related factors and, while focusing on homecare, is applicable to various healthcare settings in general. A nuanced differentiation and explanation of the elements involved enable a more consistent operationalization of the coordination concept. Additionally, as they explicitly address the healthcare system's micro, meso, and macro levels, they can be applied across diverse healthcare settings to investigate homecare coordination.

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.

Patterns of Medication Management and Associated Medical and Clinical Features among Home-Dwelling Older Adults: A Cross-Sectional Study in Central Portugal

Ageing is frequently associated with multimorbidity and polypharmacy. The present study aimed to identify the current medication management patterns and the profiles of home-dwelling older adults and to find any association with their conditions, including frailty and cognitive impairment. Within the scope of this cross-sectional study, 112 older adults living in the community were assessed via face-to-face structured interviews. Frailty, cognitive status, medication management and clinical and sociodemographic variables were evaluated. Descriptive and inferential statistics were calculated. The mean participant age was 76.6 ± 7.1 years, 53.6% of participants were women, and 40.2% of participants lived alone. More than half were classified as having frailty (58.9%), almost one-fifth (19.6%) presented with a moderate cognitive impairment had more than one disease, and 60.7% were polymedicated. No associations were found between polymedication and medication self-management, the use of over-the-counter medications, living alone, having a poor understanding of pharmacological therapy and/or pathology, or having more than one prescriber. Self-management was associated with age, the number of medications, frailty and cognitive status. Binary logistic regressions showed that cognitive impairment had statistically significant differences with medication management, having a poor understanding of pharmacological therapy and/or pathology, having one prescriber and the use of medications not prescribed by physicians. Interventions to prevent medication-related problems in home-dwelling older adults are recommended.

Subcutaneous Drugs and Off-label Use in Hospice and Palliative Care: A Scoping Review

BACKGROUND

Subcutaneous drug administration is an interesting approach for symptom control in hospice and palliative care. However, most drugs have no marketing authorization for subcutaneous administration and are therefore used off-label. In order to meet the requirements of a safe and effective drug therapy, especially in highly vulnerable patients, it is essential to investigate the scope of evidence of these common practices.

OBJECTIVES

The purpose of this scoping review was to provide an overview of available data on the tolerability and/or effectiveness of subcutaneously administered and off-label used drugs.

METHOD

We performed a scoping review according to the PRISMA extension to identify data available on the tolerability and/or effectiveness of 17 predefined drugs that are commonly administered subcutaneously in Swiss hospices and hospice-like institutions and that have no marketing authorization (off-label use).

RESULTS

The scoping review identified 57 studies with most data available on their tolerability (68% local, 54% systemic), clinical effects (82%), details on dosage (96%) and routes of application (100%). Information on pharmacokinetic properties was mostly missing and only available for fentanyl, levetiracetam, midazolam, and ondansetron. For seven drugs, less than five articles were identified and no studies on codeine or clonazepam were available.

CONCLUSION

This work provides an overview of current evidence on subcutaneous and off-label used drugs in hospice and palliative care. Although both are common practices, evidence on tolerability and effectiveness, particularly pharmacokinetic data, is limited and the identified information gaps need to be closed. This work establishes a basis for further research in this area.

Prescription Trends in Hospice Care: A Longitudinal Retrospective and Descriptive Medication Analysis

BACKGROUND

In hospice and palliative care, drug therapy is essential for symptom control. However, drug regimens are complex and prone to drug-related problems. Drug regimens must be simplified to improve quality of life and reduce risks associated with drug-related problems, particularly at end-of-life. To support clinical guidance towards a safe and effective drug therapy in hospice care, it is important to understand prescription trends.

OBJECTIVES

To explore prescription trends and describe changes to drug regimens in inpatient hospice care.

DESIGN

We performed a retrospective longitudinal and descriptive analysis of prescriptions for regular and as-needed (PRN) medication at three timepoints in deceased patients of one Swiss hospice.

SETTING/SUBJECTS

Prescription records of all patients (≥ 18 years) with an inpatient stay of three days and longer (admission and time of death in 2020) were considered eligible for inclusion.

RESULTS

Prescription records of 58 inpatients (average age 71.7 ± 12.8 [37-95] years) were analyzed. The medication analysis showed that polypharmacy prevalence decreased from 74.1% at admission to 13.8% on the day of death. For regular medication, overall numbers of prescriptions decreased over the patient stay while PRN medication decreased after the first consultation by the attending physician and increased slightly towards death.

CONCLUSIONS

Prescription records at admission revealed high initial rates of polypharmacy that were reduced steadily until time of death. These findings emphasize the importance of deprescribing at end-of-life and suggest pursuing further research on the contribution of clinical guidance towards optimizing drug therapy and deprescribing in inpatient hospice care.

Unplanned nursing home admission among discharged polymedicated older inpatients: a single-centre, registry-based study in Switzerland

OBJECTIVE

To investigate patient characteristics and the available health and drug data associated with unplanned nursing home admission following an acute hospital admission or readmission.

DESIGN

A population-based hospital registry study.

SETTING

A public hospital in southern Switzerland (Valais Hospital).

PARTICIPANTS

We explored a population-based longitudinal dataset of 14 705 hospital admissions from 2015 to 2018.

OUTCOME MEASURES

Sociodemographic, health and drug data, and their interactions predicting the risk of unplanned nursing home admission.

RESULTS

The mean prevalence of unplanned nursing home admission after hospital discharge was 6.1% (n=903/N=14 705). Our predictive analysis revealed that the oldest adults (OR=1.07 for each additional year of age; 95% CI 1.05 to 1.08) presenting with impaired functional mobility (OR=3.22; 95% CI 2.67 to 3.87), dependency in the activities of daily living (OR=4.62; 95% CI 3.76 to 5.67), cognitive impairment (OR=3.75; 95% CI 3.06 to 4.59) and traumatic injuries (OR=1.58; 95% CI 1.25 to 2.01) had a higher probability of unplanned nursing home admission. The number of International Classification of Diseases, 10th version diagnoses had no significant impact on nursing home admissions, contrarily to the number of prescribed drugs (OR=1.17; 95% CI 1.15 to 1.19). Antiemetics/antinauseants (OR=2.53; 95% CI 1.21 to 5.30), digestives (OR=1.78; 95% CI 1.09 to 2.90), psycholeptics (OR=1.76; 95% CI 1.60 to 1.93), antiepileptics (OR=1.49; 95% CI 1.25 to 1.79) and anti-Parkinson's drugs (OR=1.40; 95% CI 1.12 to 1.75) were strongly linked to unplanned nursing home admission.

CONCLUSIONS

Numerous risk factors for unplanned nursing home admission were identified. To prevent the adverse health outcomes that precipitate acute hospitalisations and unplanned nursing home admissions, ambulatory care providers should consider these risk factors in their care planning for older adults before they reach a state requiring hospitalisation.

Performance of a trigger tool for detecting drug-related hospital admissions in older people: analysis from the OPERAM trial

BACKGROUND

identifying drug-related hospital admissions (DRAs) in older people is difficult. A standardised chart review procedure has recently been developed. It includes an adjudication team (physician and pharmacist) screening using 26 triggers and then performing causality assessment to determine whether an adverse drug event (ADE) occurred (secondary to an adverse drug reaction, overuse, misuse or underuse) and whether the ADE contributed to hospital admission (DRA).

OBJECTIVE

to assess the performance of those triggers in detecting DRA.

DESIGN

retrospective study using data from the OPERAM (OPtimising thERapy to prevent Avoidable hospital admissions in Multimorbid older people) trial.

SETTINGS

four European medical centres.

SUBJECTS

multimorbid (≥ 3 chronic medical conditions) older (≥ 70 years) inpatients with polypharmacy (≥ 5 chronic medications) were enrolled in the OPERAM trial (N = 2,008) and followed for 12 months. We included patients with ≥1 adjudicated hospitalisation during the follow-up.

METHODS

the positive predictive value (PPV; number of DRAs identified by trigger/number of triggers) was calculated for each trigger and for the tool as a whole.

RESULTS

of 1,235 hospitalisations adjudicated for 832 patients, 716 (58%) had at least one trigger; an ADE was identified in 673 (54%) and 518 (42%) were adjudicated as DRAs. The overall PPV of the trigger tool for detecting DRAs was 0.66 [0.62-0.69].

CONCLUSIONS

this tool performs well for identifying DRAs in older people. Based on our results, a revised version of the tool was proposed but will require external validation before it can be incorporated into research and clinical practice.

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.

Factors associated with homecare coordination and quality of care: a research protocol for a national multi-center cross-sectional study

INTRODUCTION

The persistent fragmentation of home healthcare reflects inadequate coordination between care providers. Still, while factors at the system (e.g., regulations) and organisational (e.g., work environment) levels crucially influence homecare organisation, coordination and ultimately quality, knowledge of these factors and their relationships in homecare settings remains limited.

OBJECTIVES

This study has three aims: [1] to explore how system-level regulations lead to disparities between homecare agencies' structures, processes and work environments; [2] to explore how system- and organisation-level factors affect agency-level homecare coordination; and [3] to explore how agency-level care coordination is related to patient-level quality of care.

DESIGN AND METHODS

This study focuses on a national multi-center cross-sectional survey in Swiss homecare settings. It will target 100 homecare agencies, their employees and clients for recruitment, with data collection period planned from January to June 2021. We will assess regulations and financing mechanisms (via public records), agency characteristics (via agency questionnaire data) and homecare employees' working environments and coordination activities, as well as staff- and patient-level perceptions of coordination and quality of care (via questionnaires for homecare employees, clients and informal caregivers). All collected data will be subjected to descriptive and multi-level analyses.

DISCUSSION

The first results are expected by December 2021. Knowledge of factors linked to quality of care is essential to plan and implement quality improvement strategies. This study will help to identify modifiable factors at multiple health system levels that might serve as access points to improve coordination and quality of care.

Medication-related problems during transfer from hospital to home care: baseline data from Switzerland

Background The shift from inpatient to ambulatory care has resulted in an increase in home care patients. Little is known regarding medication safety associated with patient transfer from hospital to home care. Objective To evaluate medication-related problems in patients transferring from hospital to home care in Switzerland. Setting A non-for-profit home care organization in the city of Lucerne/Switzerland. Methods We conducted a prospective observational study, including patients aged ≥ 64 years and receiving ≥ 4 medications at hospital discharge. Two structured questionnaires assessing the transfer process were completed by home care nurses. Prescription quality was assessed using a PCNE Type 2b Medication Review. Main outcome measures The quality of the transfer process was measured comparing agreed-upon with reported parameters. Prescription quality was analyzed assessing the unambiguity of the prescription. Potentially inappropriate medications (Priscus^® list), contraindications, duplications and interactions, and clinical pharmacist-identified potential medication-related problems were collected. Results Study patients (n = 100) received 8.6 ± 3.5 regularly administered medications. Only 5/100 patients had a complete set of written discharge information. At the time of the first visit, 13/100 patients had no written medication information available. Discharge medication prescriptions were clear to nurses in 62% of patients. In 20 patients, the required medications were unavailable, resulting in 19 medication errors. Assessment by a clinical pharmacist revealed only 33/100 patients had a clear discharge prescription. Of a total of 984 prescribed drugs, 16% were considered to be ambiguous, 22 (2.2%) were potentially inappropriate. 7/984 drugs were contraindicated, 8 were duplicates. Conclusion In addition to the known risk factors in patients transferring from hospital to home care (age, polymedication, multiple providers), 3 major problems impacted upon medication safety: fragmented communication, unreliable medication availability and a poor prescription quality. Clinical pharmacists are an important option to improve medication safety ass.

A combined intervention to reduce interruptions during medication preparation and double-checking: a pilot-study evaluating the impact of staff training and safety vests

AIM

The aim was to evaluate the impact of staff training and wearing safety vests as a combined intervention on interruptions during medication preparation and double-checking.

BACKGROUND

Interruptions and errors during the medication process are common and an important issue for patient safety in the hospital setting.

METHODS

We performed a pre- and post-intervention pilot-study using direct structured observation of 26 nurses preparing and double-checking 431 medication doses (225 pre-intervention and 206 post-intervention) for 36 patients (21 pre-intervention and 15 post-intervention).

RESULTS

With staff training and the introduction of safety vests, the interruption rate during medication preparation was reduced from 36.8 to 28.3 interruptions per hour and during double-checking from 27.5 to 15 interruptions per hour.

CONCLUSION

This pilot-study showed that the frequency of interruptions decreased during the critical tasks of medication preparation and double-checking after the introduction of staff training and wearing safety vests as part of a quality improvement process.

IMPLICATIONS FOR NURSING MANAGEMENT

Nursing management should acknowledge interruptions as an important factor potentially influencing medication safety. Unnecessary interruptions can be successfully reduced by considering human and system factors and increasing both staff and nursing managers' awareness of 'interruptive communication practices' and implementing physical barriers. This is the first pilot-study specifically evaluating the impact of staff training and wearing safety vests on the reduction of interruptions during medication preparation and double-checking.

Medication safety in the home care setting: Development and piloting of a Critical Incident Reporting System

Background: While drug-related problems are among the most frequent adverse events in health care, little is known about their type and prevalence in home care in the current literature. The use of a Critical Incident Reporting System (CIRS), known as an economic and efficient tool to record medication errors for subsequent analysis, is widely implemented in inpatient care, but less established in ambulatory care. Recommendations on a possible format are scarce. A manual CIRS was developed based on the literature and subsequently piloted and implemented in a Swiss home care organization. Aim: The aim of this work was to implement a critical incident reporting system specifically for medication safety in home care. Results: The final CIRS form was well accepted among staff. Requiring limited resources, it allowed preliminary identification and trending of medication errors in home care. The most frequent error reports addressed medication preparation at the patients’ home, encompassing the following errors: omission (30 %), wrong dose (17.5 %) and wrong time (15 %). The most frequent underlying causes were related to working conditions (37.9 %), lacking attention (68.2 %), time pressure (22.7 %) and interruptions by patients (9.1 %). Conclusions: A manual CIRS allowed efficient data collection and subsequent analysis of medication errors in order to plan future interventions for improvement of medication safety. The development of an electronic CIRS would allow a reduction of the expenditure of time regarding data collection and analysis. In addition, it would favour the development of a national CIRS network among home care institutions.

[Medication safety in the home care setting: error-prone process steps]

So far, little is known about drug-related problems in the homecare setting. It is estimated that up to 30% of homecare patients experience a potential medication error, most frequently happening during preparation and administration of drugs. In order to identify error-prone process steps in a Swiss homecare organisation caring for 1854 patients per year, direct observation of the medication use process, including the analysis of 10% of all prescriptions, was executed. Three complimentary methods were combined for the assessment of qualitative aspects of the medication use process: the analysis of a critical incident reporting system, a survey among homecare nurses, and a failure, mode and effects analysis. The medication use process is complex, consisting of 20 individual steps. Patients are prescribed an average of 7.5 ± 3.5 drugs per day, including 1 to 9 doses not suitable for deblistering into weekly dispensing systems. Of 84 reported errors, 74% happened during drug preparation. Communication with physicians, patients interrupting drug preparation and not transmitted changes of the drug regimen were considered the most critical process steps.

[Assessment, frequency, causes, and prevention of medication errors - a critical analysis]

Medication errors are responsible for up to 50% of errors in healthcare. Therefore, they are an important target for the improvement of patient safety. The application of evidence-based methods for the analysis of institution-specific medication safety hotspots is crucial. Recommended methods for the identification of medication safety problems have individual strengths and weaknesses, but there is little overlap. Consequently, a combination of methods is recommended. While the analysis of critical incident reporting systems preferentially identifies serious medication errors, trigger tool represents an effective and cost-efficient approach. Evidence-based data for improvement methods is limited. However, the implementation of clinical pharmacy services, IT tools (electronic prescribing, barcoding) and standardized double-check showed a significant impact on error reduction. In addition, the support of institutional leadership is an important prerequisite.

The FDA extended warning for intravenous haloperidol and torsades de pointes: how should institutions respond?

BACKGROUND

In September 2007, the Food and Drug Administration (FDA) strengthened label warnings for intravenous (IV) haloperidol regarding QT prolongation (QTP) and torsades de pointes (TdP) in response to adverse event reports. Considering the widespread use of IV haloperidol in the management of acute delirium, the specific FDA recommendation of continuous electrocardiogram (ECG) monitoring in this setting has been associated with some controversy. We reviewed the evidence for the FDA warning and provide a potential medical center response to this warning.

METHODS

Cases of intravenous haloperidol-related QTP/TdP were identified by searching PubMed, EMBASE, and Scopus databases (January 1823 to April 2009) and all FDA MedWatch reports of haloperidol-associated adverse events (November 1997 to April 2008).

RESULTS

A total of 70 of IV haloperidol-associated QTP and/or TdP were identified. There were 54 reports of TdP; 42 of these events were reportedly preceded by QTP. When post-event QTc data were reported, QTc was prolonged >450 msec in 96% of cases. Three patients experienced sudden cardiac arrest. Sixty-eight patients (97%) had additional risk factors for TdP/prolonged QT, most commonly receipt of concomitant proarrhythmic agents. Patients experiencing TdP received a cumulative dose of 5 mg to 645 mg, patients with QTP alone received a cumulative dose of 2 mg to 1540 mg.

CONCLUSIONS

While administration of IV haloperidol can be associated with QTP/TdP, this complication most often took place in the setting of concomitant risk factors. Importantly, the available data suggest that a total cumulative dose of IV haloperidol of <2 mg can safely be administered without ongoing electrocardiographic monitoring in patients without concomitant risk factors.

[Interaction between an antiinfective agent and an immunosuppressant after liver transplantation]

Interactions between immunosuppressants and antiinfectives are most important in pharmacotherapy. Patients receiving this drug combination must be monitored carefully. Individual dose adaptation and therapeutic drug monitoring (TDM) according to the SOAP scheme (subjective data, objective data, analysis, plan) are exemplified by the case report of a 47-year-old patient who had undergone a liver transplantation.
