Initiation of antipsychotics after moving to residential aged care facilities and mortality: a national cohort study.

ABSTRACT:

Background

There is a high burden of antipsychotic use in residential aged care facilities (RACFs) and there is concern regarding potential inappropriate prescribing of antipsychotics in response to mild behavioural symptoms. Antipsychotic use has been associated with a higher risk of mortality in community-dwelling older adults with dementia, but few studies have examined associations upon RACF entry.

Aims

To examine associations between incident antipsychotic use and risk of mortality for people with and without diagnosed dementia in RACFs.

Methods

A retrospective cohort study, employing a new-user design (individuals did not receive an antipsychotic 6 months before enrolment) of 265,820 people who accessed RACFs in Australia between 1/4/2008 and 30/6/2015 was conducted. Cox regression models were used to examine adjusted associations between antipsychotic use in the first 100 days of RACF entry and mortality.

Results

In the 100 days after entering care, 29,455 residents (11.1%) were dispensed an antipsychotic. 180,956 (68.1%) residents died [38,249 (14.4%) were related to cerebrovascular causes] over a median 2.1 years (interquartile range 1.0-3.6) follow-up. Of the residents included, 119,665 (45.0%) had a diagnosis of dementia. Incident antipsychotic use was associated with higher risk of mortality in residents with dementia (adjusted hazard ratio 1.20, 95% confidence interval 1.18-1.22) and without dementia (1.28, 1.24-1.31).

Conclusion

Initiation of antipsychotics after moving to RACFs is associated with a higher risk of mortality. Careful consideration of the potential benefits and harms should be given when starting a new prescription for antipsychotics for people moving to RACFs.

Project description:BackgroundThe provision of residential aged care is underpinned by information, and is reliant upon systems that adequately capture and effectively utilise and communicate this information. The aim of this study was to explicate and quantify the volume and method by which information is collected, exchanged within facilities and with external providers, and retrieved from facility information systems and hospitals.MethodsA survey of staff (n = 119), including managers, health informatics officers (HIOs), quality improvement staff, registered nurses (RNs), enrolled nurses (ENs)/endorsed enrolled nurses (EENs) and assistants in nursing (AINs) was carried out in four residential aged care facilities in New South Wales and Victoria, Australia. Sites varied in size and displayed a range of information technology (IT) capabilities. The survey investigated how and by whom information is collected, retrieved and exchanged, and the frequency and amount of time devoted to these tasks. Descriptive analysis was performed using SPSS, and open responses to questions were coded into key themes.ResultsStaff completed a median of six forms each, taking a median of 30 min per shift. 68.8% of staff reported transferring information from paper to a computer system, which took a median of 30 min per shift. Handover and face-to-face communication was the most frequently used form of information exchange within facilities. There was a large amount of faxing and telephone communication between facility staff and General Practitioners and community pharmacists, with staff reporting sending a median of 2 faxes to pharmacy and 1.5 faxes to General Practitioners, and initiating 2 telephone calls to pharmacies and 1.5 calls to General Practitioners per shift. Only 38.5% of respondents reported that they always had information available at the point-of-care and only 35.4% of respondents reported that they always had access to hospital stay information of residents after hospital discharge.ConclusionsThis survey identified a high volume of information exchange activities, as well as inefficient procedures, such as the transfer of information from paper to computer systems and the reliance upon faxes for communication with external providers. These findings contribute to evidence for the need for interoperable IT systems to allow more efficient and reliable information exchange between facilities and external providers.

Project description:BackgroundInformation about the feasibility, barriers and facilitators of antimicrobial stewardship (AMS) in residential aged care facilities (RACFs) has been scant. Exploring the prevailing perceptions and attitudes of key healthcare providers towards antibiotic prescribing behaviour, antibiotic resistance and AMS in the RACF setting is imperative to guide AMS interventions.MethodsSemi-structured interviews and focus groups were conducted with key RACF healthcare providers until saturation of themes occurred. Participants were recruited using purposive and snowball sampling. The framework approach was applied for data analysis.ResultsA total of 40 nurses, 15 general practitioners (GPs) and 6 pharmacists from 12 RACFs were recruited. Five major themes emerged; perceptions of current antibiotic prescribing behaviour, perceptions of antibiotic resistance, attitude towards and understanding of AMS, perceived barriers to and facilitators of AMS implementation, and feasible AMS interventions. A higher proportion of GPs and pharmacists compared with nurses felt there was over-prescribing of antibiotics in the RACF setting. Antibiotic resistance was generally perceived as an issue for infection control rather than impacting clinical decisions. All key stakeholders were supportive of AMS implementation in RACFs; however, they recognized barriers related to workload and logistical issues. A range of practical AMS interventions were identified, with nursing-based education, aged-care specific antibiotic guidelines and regular antibiotic surveillance deemed most useful and feasible.ConclusionsAreas of antibiotic over-prescribing have been identified from different healthcare providers' perspectives. However, concern about the clinical impact of antibiotic resistance was generally lacking. Importantly, information gathered about feasibility, barriers and facilitators of various AMS interventions will provide important insights to guide development of AMS programs in the RACF setting.

Project description:BACKGROUND:When healthcare professionals' workloads are greater than available resources, care activities can be missed, omitted or delayed, potentially leading to adverse patient outcomes. Prioritisation, a precursor to missed care, involves decision-making about the order of care task completion based on perceived importance or urgency. Research on prioritisation and missed care has predominantly focused on acute care settings, which differ from residential aged care facilities in terms of funding, structure, staffing levels, skill mix, and approaches to care. The objective of this study was to investigate how care staff prioritise the care provided to residents living in residential aged care. METHODS:Thirty-one staff members from five Australian residential aged care facilities engaged in a Q sorting activity by ranking 34 cards representing different care activities on a pre-defined grid from 'Least important' (-?4) to 'Most important' (+?4). Concurrently, they participated in a think-aloud task, verbalising their decision-making processes. Following sorting, participants completed post-sorting interviews, a demographics questionnaire and semi-structured interviews. Q sort data were analysed using centroid factor analysis and varimax rotation in PQMethod. Factor arrays and data from the think-aloud task, field notes and interviews facilitated interpretation of the resulting factors. RESULTS:A four-factor solution, representing 22 participants and 62% of study variance, satisfied the selection criteria. The four distinct viewpoints represented by the solution were: 1. Prioritisation of clinical care, 2. Prioritisation of activities of daily living, 3. Humanistic approach to the prioritisation of care, and 4. Holistic approach to the prioritisation of care. Participants' prioritisation decisions were largely influenced by their occupations and perceived role responsibilities. Across the four viewpoints, residents having choices about their care ranked as a lower priority. CONCLUSIONS:This study has implications for missed care, as it demonstrates how care tasks deemed outside the scope of staff members' defined roles are often considered a lower priority. Our research also shows that, despite policy regulations mandating person-centred care and the respect of residents' preferences, staff members in residential aged care facilities tend to prioritise more task-oriented aspects of care over person-centredness.

Project description:BackgroundThe aged care system in Australia is under pressure. Residential aged care facilities (RACFs) and general practitioners (GPs) have difficulty providing the care needed by their residents, particularly after hours. Many residents are given ambulance support and transferred to hospital emergency departments (EDs) for care that could be provided at RACFs. The MyEmergencyDoctor (MED) service was commissioned in a 12-month program (February 2020-February 2021) using ED physicians to provide afterhours telehealth care in six RACFs.MethodsUsing the NASSS framework, we synthesised descriptive analyses of statistical data from the MED service, RACFs and the ambulance service and a thematic analysis of interview data collected from GPs, RACF and MED service staff, and family members of residents.ResultsMost calls to MED (179/209) were resolved with in-house treatment thereby reducing ambulance usage and hospital admissions. Interviews further revealed that MED enabled timely care for residents who were unwell but did not need hospital transfer. Technology, training, and rapid access to MED assisted RACF staff and complemented usual GP care. MED potentially reduced GP burnout. Refresher training was considered important especially in RACFs with high staff turnover, as was greater afterhours access to medications.ConclusionsThe afterhours telehealth model provided in-house care and reduced ambulance transfers, and GPs and RACF staff generally felt supported. The service was easy to use and fostered good communications with GPs and RACF staff. Some GPs preferred to provide their own care, commenting on the need for a good understanding of patient and family needs and of the local context. Other stakeholders suggested this model could be extended to palliative care settings and to normal business hours when GPs were unavailable. The reduced ambulance and hospital use suggested benefits to wider health systems, however policies and funding that remunerate GPs, support community-based care and provide additional staffing in RACFs are needed to sustain afterhours telehealth in RACFs. Use of the NASSS (non-adoption, abandonment, scale-up, spread, and sustainability) Framework provided a valuable explanatory lens for our analyses.

Project description:INTRODUCTION:The aged population is increasing rapidly across the world and this is expected to continue. People living in residential aged care facilities (RACFs) represent amongst the sickest and frailest cohort of the aged population, with a high prevalence of chronic conditions and complex comorbidities. Given the vulnerability of RACF residents and the demands on the system, there is a need to determine the extent that care is delivered in line with best practice ('appropriate care') in RACFs. There is also a recognition that systems should provide care that optimises quality of life (QoL), which includes support for physical and psychological well-being, independence, social relationships, personal beliefs and a caring external environment. The aims of CareTrack Aged are to develop sets of indicators for appropriate care and processes of care for commonly managed conditions, and then assess the appropriateness of care delivered and QoL of residents in RACFs in Australia. METHODS AND ANALYSIS:We will extract recommendations from clinical practice guidelines and, using expert review, convert these into sets of indicators for 15 common conditions and processes of care for people living in RACFs. We will recruit RACFs in three Australian states, and residents within these RACFs, using a stratified multistage sampling method. Experienced nurses, trained in the CareTrack Aged methods ('surveyors'), will review care records of recruited residents within a 1-month period in 2019 and 2020, and assess the care documented against the indicators of appropriate care. Surveyors will concurrently assess residents' QoL using validated questionnaires. ETHICS AND DISSEMINATION:The study has been reviewed and approved by the Human Research Ethics Committee of Macquarie University (5201800386). The research findings will be published in international and national journals and disseminated through conferences and presentations to interested stakeholder groups, including consumers, national agencies, healthcare professionals, policymakers and researchers.
