Process evaluation of a complex intervention to optimize quality of prescribing in nursing homes (COME-ON study)

'We listened and supported and depended on each other': a qualitative study of how leadership influences implementation of QI interventions

BACKGROUND

There is growing recognition in the literature of the 'Herculean' efforts required to bring about change in healthcare processes and systems. Leadership is recognised as a critical lever for implementation of quality improvement (QI) and other complex team-level interventions; however, the processes by which leaders facilitate change are not well understood. The aim of this study is to examine 'how' leadership influences implementation of QI interventions.

METHODS

We drew on the leadership literature and used secondary data collected as part of a process evaluation of the Safer Care for Older Persons in residential Environments (SCOPE) QI intervention to gain insights regarding the processes by which leadership influences QI implementation. Specifically, using detailed process evaluation data from 31 unit-based nursing home teams we conducted a thematic analysis with a codebook developed a priori based on the existing literature to identify leadership processes.

RESULTS

Effective leaders (ie, those who care teams felt supported by and who facilitated SCOPE implementation) successfully developed and reaffirmed teams' commitment to the SCOPE QI intervention (theme 1), facilitated learning capacity by fostering follower participation in SCOPE and empowering care aides to step into team leadership roles (theme 2) and actively supported team-oriented processes where they developed and nurtured relationships with their followers and supported them as they navigated relationships with other staff (theme 3). Together, these were the mechanisms by which care aides were brought on board with the intervention, stayed on board and, ultimately, transplanted the intervention into the facility. Building learning capacity and creating a culture of improvement are thought to be the overarching processes by which leadership facilitates implementation of complex interventions like SCOPE.

CONCLUSIONS

Results highlight important, often overlooked, relational and sociocultural aspects of successful QI leadership in nursing homes that can guide the design, implementation and scaling of complex interventions and can guide future research.

Factors promoting and impeding efforts to deprescribe antidepressants among nursing home residents with dementia- a process evaluation guided by normalization process theory

BACKGROUND

Despite recommendations against psychotropic medication in older nursing homes residents with behavioral and psychological symptoms of dementia (BPSD), antidepressants and other psychotropic drugs are still prescribed. We performed a cluster-randomized controlled trial to evaluate the effect of a complex intervention aiming to promote the deprescribing of antidepressants in institutionalized older persons with dementia. To understand the underlying mechanisms of trial outcomes, we conducted a process evaluation exploring the interventions implementation, areas of impact, and contextual factors. The aim of this study was to explore the implementation process and the key factors that promoted and inhibited intervention implementation in the care home setting (Clinicaltrials.gov: NCT04985305. Registered 30 July 2021).

METHODS

Qualitative interviews were conducted between August 2022 and February 2023 with four general practitioners and eight nursing home staff from four associated nursing homes in the Capital Region of Denmark. We coded the interview data according to the four constructs of the Normalization Process Theory (coherence, cognitive participation, collective action, and reflexive monitoring).

RESULTS

There was a common understanding of the intervention aim. We observed a raised awareness concerning the deprescription of antidepressants among healthcare professionals with good collaboration (coherence). An overall buy-in to a deprescribing mentality was seen (cognitive participation). There were barriers to the GPs and nursing home staff's use of the intervention elements and how they implemented it, but to some, a common language was created (collective action). Professionals overall valued the idea of deprescribing, but lack of time, high staff turnover, and low education level among nursing home staff hampered the integration (reflexive monitoring).

CONCLUSION

Successful implementation seemed to be dependent on the quality of the relationship between the single GP and the single nursing home professional. A common deprescribing mentality promoted the uptake of the intervention. However, several barriers related to lack of resources hindered implementation. It is imperative to adapt complex interventions to the available resources and context.

Use of qualitative methods to optimize collaborative practices by highlighting differences in perceptions between professionals: an example of patient education

Interprofessional working must be approached within health promotion interventions using systematic methods to identify areas of suboptimal collaboration. We designed a qualitative study with a purposive sample of seven French therapeutic patient education programs. Semi-structured individual interviews were conducted with 14 healthcare providers and seven clinician leaders (coordinators) involved in patient education. We used the same interview guide and thematic grid regardless of the professional's profile to compare their perceptions on elements affecting outcome, participation and sustainability of programs. Healthcare providers and coordinators addressed non-convergent issues at both ends of a continuum from a micro-level nested in the program delivery to a macro-level corresponding to the structured implementation and sustainability of the program. Meso-level issues featured convergent perspectives. Our methodology could be used at the level of health services in a health system to provide a complete recovery of stakeholders' perspectives (without "blind spots" from one stakeholder or another). In our study, we focused on patient education in the French health system and pointed out possible considerations to optimize the functioning of programs. Such considerations include specific training plan development, encouraging reflection on the content and use of initial assessment, leading sessions in pairs to save on work time, and communication on the ins and outs of organizational imperatives that require healthcare providers' contributions.

Implementation of interprofessional quality circles on deprescribing in Swiss nursing homes: an observational study

BACKGROUND

Polypharmacy and potentially inappropriate medications (PIMs) are still frequent among older adults in nursing homes. Deprescribing is an intervention that has been shown to be effective in reducing their use. However, the implementation of deprescribing in clinical practice has not yet been widely evaluated. The Quality Circle Deprescribing Module (QC-DeMo) intervention has been trialled through an effectiveness-implementation hybrid type 2 design. The intervention consists of a quality circle workshop session between healthcare professionals HCPs (physicians, nurses, and pharmacists) within a nursing home, in which they define a consensus to deprescribe specific PIMs classes. The aim of this study was to evaluate the implementation of the QC-DeMo intervention in nursing homes.

METHODS

This observational study focuses on the implementation part of the QC-DeMo trial. Implementation was based on the Framework for Implementation of Pharmacy Services (FISpH). Questionnaires at baseline and follow-up were used to evaluate reach, adoption, implementation effectiveness, fidelity, implementation, maintenance and the implementation strategies. Other data were collected from the QC-DeMo trial and routine data collected as part of the integrated pharmacy service where the QC-Demo trial was embedded. Implementation strategies included training of pharmacists, integration of the intervention into an existing quality circle dynamic and definition of tailored strategies to operationalise the consensus by each nursing home.

RESULTS

The QC-DeMo intervention was successfully implemented in 26 nursing homes in terms of reach, fidelity, adoption, implementation and implementation effectiveness. However, the intervention was found to be implemented with low maintenance as none of the nursing homes repeated the intervention after the trial. Implementation strategies were well received by HCPs: training was adequate according to pharmacists. Pre-existing quality circle dynamic facilitated interprofessional collaboration as involvement and support of each HCP was rated as high. HCPs recognized a specific and important role for each HCP in the deprescribing process. The most relevant tailored strategies to implement the consensus defined by each nursing home were identification of the patients by the pharmacist and a systematic review of medication's patients.

CONCLUSIONS

The implementation of a Quality Circle on Deprescribing is feasible but its maintenance in practice remains challenging. This study explores multiple implementation outcomes to better inform future implementation efforts of these types of interventions.

Preliminary Evidence for Dementia Collaborative Coaching

PURPOSE

The primary purpose of this study was to obtain preliminary evidence for a communication coaching intervention, Dementia Collaborative Coaching. The secondary aim of this study was to assess the acceptability, appropriateness, and feasibility of the intervention according to routine care providers.

METHOD

In a pre-/posttest design, speech-language pathologists (SLPs) delivered Dementia Collaborative Coaching to certified nursing assistants (CNAs) and people living with dementia (PLWD) in six different skilled nursing facilities over a period of 6 weeks. A self-perceived knowledge and efficacy measure regarding the use of external memory aids to support communication in PLWD was administered to CNA and SLP participants. The Cohen-Mansfield Agitation Inventory was administered to PLWD participants. The Acceptability of Intervention Measure, Intervention Appropriateness Measure, and Feasibility of Intervention Measure were administered post-intervention.

RESULTS

For CNAs, self-perceived knowledge and efficacy increased from pre-intervention (M = 3.73, SD = 0.69) to post-intervention (M = 4.07, SD = 0.44), t(11) = -1.97, one-sided p = .037. There was a significant improvement (e.g., reduction) in scores on the Cohen-Mansfield Agitation Inventory for PLWD (n = 10) from pre-intervention (M = 73.10, SD = 29.98) to post-intervention (M = 58.6, SD = 18.82), t(9) = 2.83, p = .01. CNA participants (n = 12) rated the intervention as acceptable (M = 4.48, SD = 0.48), appropriate (M = 4.33, SD = 0.61), and feasible (M = 4.19, SD = 0.48). SLPs rated the intervention as slightly more acceptable, appropriate, and feasible than CNAs with scores of M = 4.54, SD = 0.51; M = 4.54, SD = 0.51; and M = 4.46, SD = 0.51, respectively.

CONCLUSIONS

Dementia Collaborative Coaching showed preliminary positive outcomes for CNAs and PLWD. The intervention was acceptable, appropriate, and feasible for routine providers and warrants further study.

Intervention of pharmacist included in multidisciplinary team to reduce adverse drug event: a qualitative systematic review

BACKGROUND

Preventable harm in healthcare is a growing public health challenge. In addition to the economic costs of safety failures, adverse drug events (ADE) may lead to complication or even death. Multidisciplinary care team involving a pharmacist appears to be an adequate response to prevention of adverse drug event. This qualitative systematic review aims to identify and describe multidisciplinary planned team-based care involving at least one pharmacist to limit or prevent adverse drug events in the adult patients.

METHODS

To determine the type of interprofessional collaboration to prevent adverse drug event in which a pharmacist was involved, we conducted a qualitative systematic review of the literature of randomized controlled trials. Two independent reviewers screened trials in three databases: Medline, Web of Science, ScienceDirect. Prospective studies of at least three different health professionals' interventions, one of whom was a pharmacist in the last five years were included. Two reviewers performed data extraction and quality appraisal independently. We used TIDieR checklist to appraise articles quality.

RESULTS

In total 803 citations were retrieved, 34 were analysed and 16 full-text articles were reviewed. Only 3 studies published an implementation evaluation. More than half of the interventions (62%) targeted elderly patients including 6 whom lived in nursing homes. Studies outcomes were heterogeneous, and we did not perform a statistical analysis of the impact of these interventions. Most teams are composed of a physician/pharmacist/nurse trio (94%; 100%; 88%). Half of the teams were composed of the primary care physician. Other professionals were included such as physical therapists (25%), social worker (19%), occupational therapists (12%), and community health educator (6%). Multidisciplinary medication review was the most common intervention and was generally structured in four steps: data collection and baseline assessment, appraisal report by health professionals, a multidisciplinary medication review meeting and a patient follow-up.

CONCLUSIONS

The most common multidisciplinary intervention to prevent ADE in the adult population is the multidisciplinary drug review meeting at least the physician/pharmacist/nurse trio. Interventions target mostly elderly people in nursing homes, although complex chronic patients could benefit from this type of assessment.

Teaching and learning modalities for continuing professional development in the long-term care: A rapid synthesis review

AIM

To describe the various teaching and learning modalities for the delivery of Continuing Professional Development activities for health care professionals in the long-term care sector.

BACKGROUND

Continuing Professional Development is a key activity that organisations undertake to achieve effective workforce planning, recruitment, retention and upskilling strategies in long-term care settings. During the Covid-19 pandemic there was a rapid move to online modalities of Continuous Professional Development, but there is a paucity of evidence in relation to their effectiveness compared with face-to-face, or in-class learning.

DESIGN

A rapid synthesis review.

METHODS

MEDLINE, CINAHL and HEALTH BUSINESS ELITE databases were used to identify relevant articles that were published between 2016 and 2022. Original studies of any design investigating Continuing Professional Development activities, with or without a comparison between interventions or activities were included. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) was followed. The Kirkpatrick model was adopted as a globally recognised method for evaluating training programmes.

RESULTS

After a full text analysis, 34 papers were included in the review. Face to face was the most common method of delivery followed by online, while blended (a mix of face-to-face and online delivery) was the least common method used. The teaching modalities were not associated with specific learning contents, but were used for a range of content. Most studies obtained positive outcomes following implementation of the educational interventions. Kirkpatrick Level 4 (results) was the most commonly measured outcome.

CONCLUSIONS

While blended learning was the least common method of delivery, it was found to be more beneficial for learners than face-to-face or online exclusively. There are now new spaces to learn and new technologies that allow us to 'reimagine' where, when and how we teach. This requires Continuing Professional Development providers to design and tailor their courses according to health professionals' learning needs and the clinical contexts where they work. We recommend that Continuing Professional Development providers involve employers when designing teaching and learning activities for Long Term Care workers, to decide which modalities enable effective knowledge translation.

Contextual factors influencing complex intervention research processes in care homes: a systematic review and framework synthesis

Background

Care homes are complex settings to undertake intervention research. Barriers to research implementation processes can threaten studies’ validity, reducing the value to residents, staff, researchers and funders. We aimed to (i) identify and categorise contextual factors that may mediate outcomes of complex intervention studies in care homes and (ii) provide recommendations to minimise the risk of expensive research implementation failures.

Methods

We conducted a systematic review using a framework synthesis approach viewed through a complex adaptive systems lens. We searched: MEDLINE, Embase, CINAHL, ASSIA databases and grey literature. We sought process evaluations of care home complex interventions published in English. Narrative data were indexed under 28 context domains. We performed an inductive thematic analysis across the context domains.

Results

We included 33 process evaluations conducted in high-income countries, published between 2005 and 2019. Framework synthesis identified barriers to implementation that were more common at the task and organisational level. Inductive thematic analysis identified (i) avoiding procedural drift and (ii) participatory action and learning as key priorities for research teams. Research team recommendations include advice for protocol design and care home engagement. Care home team recommendations focus on internal resources and team dynamics. Collaborative recommendations apply to care homes’ individual context and the importance of maintaining positive working relationships.

Discussion

Researchers planning and undertaking research with care homes need a sensitive appreciation of the complex care home context. Study implementation is most effective where an intervention is co-produced, with agreed purpose and adequate resources to incorporate within existing routines and care practices.

Mechanisms of impact and contextual aspects of a dementia special care unit in long-term care: a process evaluation

BACKGROUND

In long-term care, persons with dementia are often cared for in specialised facilities, which are rather heterogeneous in regard to care concepts. Little information is available on how these facilities and care concepts bring about changes in the targeted outcomes. Such knowledge is needed to understand the effects of care concepts and to consciously shape further developments. This study aimed to explore the mechanisms of impact of a specific care concept from a dementia special care unit and the contextual aspects that influence its implementation or outcomes.

METHODS

Using a qualitative approach to process evaluation of complex interventions, we conducted participating observations and focus groups with nurses and single interviews with ward and nursing home managers. Data were collected from two identical dementia special care units to enhance the contrasts in the analysis of two non-specialised nursing homes. We analysed the data thematically. We conducted 16 observations, three group interviews and eleven individual interviews.

RESULTS

We identified seven themes in three domains related to mechanisms that lead to outcomes regarding residents' and nurses' behaviour and well-being. The themes include the development of nurses' skills and knowledge, the promotion of a positive work climate, adjusted spatial structures, adjusted personnel deployment strategy "dedicated time for activities", promotion of relaxation, of engagement in activities and of engagement in social interaction of residents. The implementation and outcomes of the care concept are influenced by contextual aspects relating to the (target) population and cultural, organisational and financial features.

CONCLUSIONS

The study found expected and unexpected mechanisms of impact and contextual aspects. The care concept of the dementia special care unit results in higher levels of relaxation, activities, and social interaction of residents. Its implementation highly depends on the shared understanding of nursing and the skills of the nursing team. Changes in residents' characteristics result in altered effects of the concept.

Tailored patient therapeutic educational interventions: A patient-centred communication model

Background

Tailoring therapeutic education consists of adapting the intervention to patients' needs with the expectation that this individualization will improve the results of the intervention. Communication is the basis for any individualization process. To our knowledge, there is no guide or structured advice to help healthcare providers (HCPs) tailor patient education interventions.

Objectives

We used a data‐driven qualitative analysis to (1) investigate the reasons why HCPs tailor their educational interventions and (2) identify how this tailoring is effectively conducted. The perspective aimed to better understand how to individualize therapeutic patient education and to disentangle the different elements to set up studies to investigate the mechanisms and effects of individualization.

Design

Individual semistructured interviews with 28 HCPs involved in patient education were conducted. The present study complied with the COREQ criteria.

Results

Why individualization is necessary: participants outlined that the person must be thought of as unique and that therapeutic education should be adapted to the patient's personality and cognitive abilities. The first step in the individualization process was formalized by an initial patient assessment. Several informal practices were identified: if needed, giving an individual time or involving a specific professional; eliciting individual objectives; reinforcing the relationship by avoiding asymmetrical posture; focusing on patients' concerns; leading sessions in pairs; and making the patient the actor of decisions.

Conclusion

From our thematic data analysis, a model for tailoring patient education interventions based on the Haes and Bensing medical communication framework is proposed. The present work paves the way for evaluation, then generation of recommendations and finally implementation of training for individualization in educational interventions.

Short Informative

Tailoring in therapeutic education consists of an adaptation to patients' needs. Communication is the basis for any individualization process. There is no model of patient‐centred communication in educational interventions. From semistructured interviews with HCPs, we propose a patient‐centred communication model for tailoring patient education intervention.

Complexity and involvement as implementation challenges: results from a process analysis

Background

The study objective was to analyse the implementation challenges experienced in carrying out the IMPROVE programme. This programme was designed to implement checklist-related improvement initiatives based on the national perioperative guidelines using a stepped-wedge trial design. A process analysis was carried out to investigate the involvement in the implementation activities.

Methods

An involvement rating measure was developed to express the extent to which the implementation programme was carried out in the hospitals. This measure reflects the number of IMPROVE-implementation activities executed and the estimated participation in these activities in all nine participating hospitals. These data were compared with prospectively collected field notes.

Results

Considerable variation between the hospitals was found with involvement ratings ranging from 0 to 6 (mean per measurement = 1.83 on a scale of 0–11). Major implementation challenges were respectively the study design (fixed design, time planning, long duration, repeated measurements, and data availability); the selection process of hospitals, departments and key contact person(s) (inadequately covering the entire perioperative team and stand-alone surgeons); the implementation programme (programme size and scope, tailoring, multicentre, lack of mandate, co-interventions by the Inspectorate, local intervention initiatives, intervention fatigue); and competitive events such as hospital mergers or the introduction of new IT systems, all reducing involvement.

Conclusions

The process analysis approach helped to explain the limited and delayed execution of the IMPROVE-implementation programme. This turned out to be very heterogeneous between hospitals, with variation in the number and content of implementation activities carried out. The identified implementation challenges reflect a high complexity with regard to the implementation programme, study design and setting. The involvement of the target professionals was put under pressure by many factors. We mostly encountered challenges, but at the same time we provide solutions for addressing them. A less complex implementation programme, a less fixed study design, a better thought-out selection of contact persons, as well as more commitment of the hospital management and surgeons would likely have contributed to better implementation results.

Implementation and Use of Point-of-Care C-Reactive Protein Testing in Nursing Homes

OBJECTIVES

This study evaluated logistics, process data, and barriers/facilitators for the implementation and use of C-reactive protein point-of-care testing (CRP POCT) for suspected lower respiratory tract infections (LRTIs) in nursing home (NH) residents.

DESIGN

This process evaluation was performed alongside a cluster randomized, controlled trial (UPCARE study) to evaluate the effect of CRP POCT on antibiotic prescribing for suspected LRTIs in NH residents.

SETTING AND PARTICIPANTS

Eleven NHs in the Netherlands.

METHODS

Data sources for process data regarding intervention quality included a questionnaire among NH staff, logs, reports, and CRP POCT-analyzer records. Barriers and facilitators for implementation were assessed in focus group interviews with physicians and nurses from 3 NHs.

RESULTS

Correct patient selection for CRP POCT and generally continued CRP POCT use indicated good fidelity. The initial training and training of new employees seemed to fit the need, but some POCT-user group sizes had increased over time, which could have impeded frequent use. Users were generally satisfied with CRP POCT and perceived its use feasible and relevant. Facilitators for implementation were initial commitment and active initiation, followed by continued attention and enthusiasm for building routine practice and trust. Short lines of communication between staff, short distance to the POCT-analyzer, 24/7 coverage of staff, and a clear task division facilitated continued attention and routine practice.

CONCLUSIONS AND IMPLICATIONS

This process evaluation showed sufficient quality of providing CRP POCT in Dutch NHs. We processed findings of intervention quality and implementation knowledge into key recommendations for CRP POCT implementation in this setting. Future research could focus on CRP POCT use in countries with different organization of care in NHs.

French nurses' and allied health professionals' perception of research in their fields: A descriptive qualitative study

AIM

To gather information from nurses and allied health professionals in the French context of the emergence of research in the field so as to inform the development of a new tool: The research in nursing and allied health sciences' Ideas Generator (GénI) capable of sustaining the identification of research ideas from professionals in the field.

BACKGROUND

In many countries, research in nursing and allied health sciences remains underdeveloped.

INTRODUCTION

Before developing the Ideas Generator tool, it was essential to explore professionals' basis of reference in providing care, then investigate (1) their representation of research in this field of science and (2) their perception of needs for and obstacles to starting a research process.

METHODS

The qualitative research design used focus groups. The study population included 24 participants naive to research in four hospitals in eastern France (13 nurses and 11 allied health professionals). Thematic analysis was used to analyze the data. The study was reported in compliance with the consolidated criteria for reporting qualitative research criteria.

FINDINGS

Professionals used tacit knowledge and their experiences to address care, but the culture of scientific evidence was clearly missing (lack of knowledge of the origin of care guidelines, few bibliographic skills). Participation in a research process could hardly be envisaged without a supervised collaboration with a physician. Research was perceived not to be part of professionals' culture. They self-censured for lack of methodological competencies.

DISCUSSION

Findings underlined some leverage, obstacles, and need to consider to generate a stimulation in the field, especially in countries where such research is still in its infancy.

IMPLICATION FOR NURSING, HEALTH, AND EDUCATION POLICY

Strengthening the field of nursing and allied health research is essential to extend the skills of nurses and allied health workers and to improve the quality of patient care by taking into account results from the literature. The Ideas Generator tool will be implemented to sustain learning the skills of research through education and training.

A framework for the implementation of certification procedures in nurse level: a mixed approach study

Background

The implementation of certification procedures across healthcare systems is an essential component of the management process. Several promising approaches were developed toward a successful implementation of such policies; however, a precise adaptation and implementation to each local context was essential. Local activities must be considered in order to generate more pragmatic recommendations for managers. In this study, we built a framework for the implementation of certification procedures at nurse activity level. This was developed using two objectives: the identification of key implementation process components, and the integration of these components into a framework which considered the local socio-material context of nurses’ work.

Methods

We used a two-step mixed approach. The first was inductive and consisted of a qualitative case study conducted between April and December 2019. Here, we analyzed the implementation of certification procedures in a French teaching hospital. Data were collected using semi-structured interviews and observations. In the second approach, emerging data were deductively analyzed using the Quality Implementation Tool (QIT) and Translational Mobilization Theory (TMT). Analyses were combined to construct an implementation framework.

Results

Sixteen interviews were conducted with participants from different organizational levels, managers, mid-managers, and nurses. Additionally, 83 observational hours were carried out in two different wards. Our results showed that, (1) All retrieved elements during the process were successfully captured by the QIT components, only one component was not applicable. (2) We identified elements related to the local activity context, with the different interrelationships between actors, actions, and contexts using the TMT. (3) Our analyses were integrated and translated into a framework that presents the implementation of certification procedures in healthcare facilities, with a specific interest to the nurse/mid-manager level. By initially using QIT, the framework components took on a transversal aspect which were then adapted by TMT to the local work context.

Conclusions

We successfully generated a framework that supports the implementation of certification procedures at the activity level. Our approach identified a broader vision of the interactions between proximity managers, teams, and contexts during change mobilization, which were not encompassed by transversal framework only, such as QIT. In the future, more empirical studies are needed to test this framework.

Interventions to optimize medication use in nursing homes: a narrative review

PURPOSE

Polypharmacy, medication errors and adverse drug events are frequent among nursing home residents. Errors can occur at any step of the medication use process. We aimed to review interventions aiming at optimization of any step of medication use in nursing homes.

METHODS

We narratively reviewed quantitative as well as qualitative studies, observational and experimental studies that described interventions, their effects as well as barriers and enablers to implementation. We prioritized recent studies with relevant findings for the European setting.

RESULTS

Many interventions led to improvements in medication use. However, because of outcome heterogeneity, comparison between interventions was difficult. Prescribing was the most studied aspect of medication use. At the micro-level, medication review, multidisciplinary work, and more recently, patient-centered care components dominated. At the macro-level, guidelines and legislation, mainly for specific medication classes (e.g., antipsychotics) were employed. Utilization of technology also helped improve medication administration. Several barriers and enablers were reported, at individual, organizational, and system levels.

CONCLUSION

Overall, existing interventions are effective in optimizing medication use. However there is a need for further European well-designed and large-scale evaluations of under-researched intervention components (e.g., health information technology, patient-centered approaches), specific medication classes (e.g., antithrombotic agents), and interventions targeting medication use aspects other than prescribing (e.g., monitoring). Further development and uptake of core outcome sets is required. Finally, qualitative studies on barriers and enablers for intervention implementation would enable theory-driven intervention design.

Process Evaluation of the SImplification of Medications Prescribed to Long-tErm Care Residents (SIMPLER) Cluster Randomized Controlled Trial: A Mixed Methods Study

Complex medication regimens are highly prevalent, burdensome for residents and staff, and associated with poor health outcomes in residential aged care facilities (RACFs). The SIMPLER study was a non-blinded, matched-pair, cluster randomized controlled trial in eight Australian RACFs that investigated the one-off application of a structured 5-step implicit process to simplify medication regimens. The aim of this study was to explore the processes underpinning study implementation and uptake of the medication simplification intervention. A mixed methods process evaluation with an explanatory design was undertaken in parallel with the main outcome evaluation of the SIMPLER study and was guided by an established 8-domain framework. The qualitative component included a document analysis and semi-structured interviews with 25 stakeholders (residents, family, research nurses, pharmacists, RACF staff, and a general medical practitioner). Interviews were transcribed verbatim and reflexively thematically content analyzed. Descriptive statistics were used to summarize quantitative data extracted from key research documents. The SIMPLER recruitment rates at the eight RACFs ranged from 18.9% to 48.6% of eligible residents (38.4% overall). Participation decisions were influenced by altruism, opinions of trusted persons, willingness to change a medication regimen, and third-party hesitation regarding potential resident distress. Intervention delivery was generally consistent with the study protocol. Stakeholders perceived regimen simplification was beneficial and low risk if the simplification recommendations were individualized. Implementation of the simplification recommendations varied between the four intervention RACFs, with simplification implemented at 4-month follow-up for between 25% and 86% of residents for whom simplification was possible. Good working relationships between stakeholders and new remunerated models of medication management were perceived facilitators to wider implementation. In conclusion, the one-off implicit medication simplification intervention was feasible and generally delivered according to the protocol to a representative sample of residents. Despite variable implementation, recommendations to simplify complex regimens were valued by stakeholders, who also supported wider implementation of medication simplification in RACFs.

Response and Adherence of Nursing Home Residents to a Nutrition/Exercise Intervention

OBJECTIVES

Interindividual response variability to nutrition and exercise interventions is extensive in older adults. A group of nursing home (NH) residents participated in a combined intervention. The objective of this post-hoc analysis was to identify factors associated with intervention response measured by change in physical function and body composition.

DESIGN

Post-hoc analyses in the Older Person's Exercise and Nutrition study, a 2-arm randomized trial. The primary outcomes were 30-second Chair Stand Test and composite scores combining physical function and fat-free mass. A secondary outcome was intervention adherence. A 12-week intervention of sit-to-stand exercises and protein-rich nutritional supplements did not improve chair-stand capacity vs control on intention-to-treat basis.

SETTING AND PARTICIPANTS

Residents ≥75 years of age from dementia and somatic units in eight NHs in Sweden.

METHODS

Logistic regressions were performed to define factors associated with response (maintenance/improvement) or nonresponse (deterioration) in 30-second Chair Stand Test, and with intervention adherence. Linear regressions were performed to explore factors associated with response in composite scores.

RESULTS

Mean age of participants (n = 52 intervention, n = 49 control) was 85.8 years. Sarcopenia was occurring in 74%. Sarcopenia at baseline (P = .005) and high adherence to nutritional supplements (P = .002) increased the odds of response. Higher independence in daily activities increased the odds of adherence to sit-to-stand exercises (P = .027) and the combined intervention (P = .020). Allocation to the intervention group and higher self-perceived health were associated with higher composite scores.

CONCLUSIONS AND IMPLICATIONS

NH residents with baseline sarcopenia, better self-perceived health, and high adherence to nutritional supplements benefitted most from a combined nutrition and exercise intervention regarding chair-stand capacity and composite scores of function and fat-free mass. Adherence was related to higher grade of independence. Understanding factors associated with response and adherence to an intervention will help target susceptible residents in most need of support and to optimize the outcome.

[Identification of polypharmacy-associated risks among nursing home residents]

Einleitung

Multimorbidität im Alter ist u. a. ein Grund für intensivierte Pharmakotherapie. Gleichzeitig kann es mit steigender Medikamentenzahl zu einer Zunahme der Multimorbidität kommen, insbesondere wenn Interaktionen zwischen den Wirkstoffen zu unerwünschten Arzneiwirkungen (UAW) führen. Ziel dieser Untersuchung war es, in einer Pilotstudie Patienten zu identifizieren, die einem erhöhten Risiko für UAW unterliegen.

Methoden

In einer Querschnittserhebung wurden 918 in Heimen lebende psychiatrisch behandelte Alterspatienten untersucht (Altersmittel: 79,3 (±11,6) Jahre; 31,8 % Männer). Es kamen exemplarisch verschiedene Methoden zur Identifikation von möglichen Risikopatienten zur Anwendung: eine die Interaktionen der Gesamtmedikation erfassende „Clinical-Decision-Support-Software“(CDSS)-Onlinedatenbank, mediQ, und eine Negativliste, die pauschal zu vermeidende Präparate indiziert, die PRISCUS-Liste.

Ergebnis

Es hatten 76,3 % aller Studienpatienten bei Betrachtung der Gesamtmedikation ein klinisch relevantes Interaktionsrisiko (IR), 2,2 % standen unter einem darüber hinausgehenden potenziell starken UAW-Risiko durch Interaktionen. Ungefähr ein Viertel der untersuchten Studienpopulation erhielt potenziell inadäquate Medikamente gemäß PRISCUS.

Schlussfolgerung

Diese unterschiedlichen Zahlen zeigen die Komplexität der eindeutigen Identifikation von Risikopatienten am Beispiel dieser beiden, auf unterschiedlicher Grundlage basierenden Instrumente. Trotz des technischen Fortschritts sollte der Schwerpunkt der UAW-Vermeidung unverändert darauf liegen, Medikamente erst nach besonders gründlicher Prüfung der klinischen Indikation zu verordnen und eine adäquate Verlaufskontrolle zu gewährleisten. Die neuen CDSS oder Negativlisten bieten hierbei Unterstützung.
