Primary, allied health, selected specialists, and mental health service utilisation by home care recipients in Australia before and after accessing the care, 2017-2019.

OBJECTIVES: To examine changes in primary, allied health, selected specialists, and mental health service utilisation by older people in the year before and after accessing home care package (HCP) services. METHODS: A retrospective cohort study using the Registry of Senior Australians Historical National Cohort (≥ 65 years old), including individuals accessing HCP services between 2017 and 2019 (N = 109,558), was conducted. The utilisation of general practice (GP) attendances, health assessments, chronic disease management plans, allied health services, geriatric, pain, palliative, and mental health services, subsidised by the Australian Government Medicare Benefits Schedule, was assessed in the 12 months before and after HCP access, stratified by HCP level (1-2 vs. 3-4, i.e., lower vs. higher care needs). Relative changes in service utilisation 12 months before and after HCP access were estimated using adjusted risk ratios (aRR) from Generalised Estimating Equation Poisson models. RESULTS: Utilisation of health assessments (7-10.2%), chronic disease management plans (19.7-28.2%), and geriatric, pain, palliative, and mental health services (all ≤ 2.5%) remained low, before and after HCP access. Compared to 12 months prior to HCP access, 12 months after, GP after-hours attendances increased (HCP 1-2 from 6.95 to 7.5%, aRR = 1.07, 95% CI 1.03-1.11; HCP 3-4 from 7.76 to 9.32%, aRR = 1.20, 95%CI 1.13-1.28) and allied health services decreased (HCP 1-2 from 34.8 to 30.7%, aRR = 0.88, 95%CI 0.87-0.90; HCP levels 3-4 from 30.5 to 24.3%, aRR = 0.80, 95%CI 0.77-0.82). CONCLUSIONS: Most MBS subsidised preventive, management and specialist services are underutilised by older people, both before and after HCP access and small changes are observed after they access HCP.

Primary health care service utilisation before and after entry into long-term care in Australia.

OBJECTIVES: To examine utilisation of primary health care services (subsidised by the Australian Government, Medicare Benefits Schedule, MBS) before and after entry into long-term care (LTC) in Australia. METHODS: A retrospective cohort study of older people (aged ≥65 years) who entered LTC in Australia between 2012 and 2016 using the Historical Cohort of the Registry of Senior Australians. MBS-subsidised general attendances (general practitioner (GP), medical and nurse practitioners), health assessment and management plans, allied health, mental health services and selected specialist attendances accessed in 91-day periods 12 months before and after LTC entry were examined. Adjusted relative changes in utilisation 0-3 months before and after LTC entry were estimated using risk ratios (RR) calculated using Generalised Estimating Equation Poisson models. RESULTS: 235,217 residents were included in the study with a median age of 84 years (interquartile range 79-89) and 61.1% female. In the first 3 months following LTC entry, GP / medical practitioner attendances increased from 86.6% to 95.6% (aRR 1.10 95%CI 1.10-1.11), GP / medical practitioner urgent after hours (from 12.3% to 21.1%; aRR 1.72, 95%CI 1.70-1.74) and after-hours attendances (from 18.5% to 33.8%; aRR 1.83, 95%CI 1.81-1.84) increased almost two-fold. Pain, palliative and geriatric specialist medicine attendances were low in the 3 months prior (<3%) and decreased further following LTC admission. CONCLUSION: There is an opportunity to improve the utilisation of primary health care services following LTC entry to ensure that residents' increasingly complex care needs are adequately met.

Primary, allied health, geriatric, pain and palliative healthcare service utilisation by aged care residents, 2012-2017.

OBJECTIVES: To examine the incidence and trends in primary care, allied health, geriatric, pain and palliative care service use by permanent residential aged care (PRAC) residents and the older Australian population. METHODS: Repeated cross-sectional analyses on PRAC residents (N = 318,484) and the older (≥65 years) Australian population (N ~ 3.5 million). Outcomes were Medicare Benefits Schedule (MBS) subsidised primary care, allied health, geriatric, pain and palliative services between 2012-13 and 2016-17. GEE Poisson models estimated incidence rates and incidence rate ratios (IRR). RESULTS: In 2016-17, PRAC residents had a median of 13 (interquartile range [IQR] 5-19) regular general medical practitioner (GP) attendances, 3 (IQR 1-6) after-hours attendances and 5% saw a geriatrician. Highlights of utilisation changes from 2012-13 to 2016-17 include the following: GP attendances increased by 5%/year (IRR = 1.05, 95% confidence interval [CI] 1.05-1.05) for residents compared to 1%/year (IRR = 1.01, 95%CI 1.01-1.01) for the general population. GP after-hours attendances increased by 15%/year (IRR = 1.15, 95%CI 1.14-1.15) for residents and 9%/year (IRR = 1.08, 95%CI 1.07-1.20) for the general population. GP management plans increased by 12%/year (IRR = 1.12, 95%CI 1.11-1.12) for residents and 10%/year (IRR = 1.10, 95%CI 1.09-1.11) for the general population. Geriatrician consultations increased by 28%/year (IRR = 1.28, 95%CI 1.27-1.29) for residents compared to 14%/year (IRR = 1.14, 95%CI 1.14-1.15) in the general population. CONCLUSIONS: The utilisation of most examined services increased in both cohorts over time. Preventive and management care, by primary care and allied health care providers, was low and likely influences the utilisation of other attendances. PRAC residents' access to pain, palliative and geriatric medicine services is low and may not address the residents' needs.

Aged and Health Care Service Utilization by Older Australians Receiving Home Care Packages.

OBJECTIVES: To examine the (1) cohort of individuals living at home with Home Care Packages (HCPs) in 2016, (2) their access to other aged care services after HCP commencement, and (3) their hospital and ambulance service utilization. DESIGN: A cross-sectional study was conducted using integrated aged care and health care data contained within the National Historical Cohort of the Registry of Senior Australians. SETTING AND PARTICIPANTS: This study included people who accessed HCP between January 1, 2016 and December 31, 2016. METHODS: The access to permanent residential aged care, transition care, respite care, hospital and ambulance services among Australian HCP recipients ≥65 years old in 2016 was evaluated. Descriptive statistics were employed. RESULTS: In 2016, 84,681 individuals received HCPs, of which 68.4% (n = 57,942) accessed HCP levels 1‒2, 26.0% (n = 22,057) accessed HCP levels 3‒4, and 5.5% (n = 4682) accessed both care levels within the year. Of the individuals receiving HCP, 34.0% (n = 27,787) started services that year and 16.7% (n = 14,117) moved to permanent residential aged care, 18.4% (n = 15,592) used respite care and 5.8% (n = 4937) used transition care that year. Emergency department (ED) presentations [43.6%, 95% confidence interval (CI) 43.3‒44.0] were the most common hospital encounters, followed by inpatient hospitalizations for any reason (43.3%, 95% CI 42.9‒43.7), and unplanned hospitalizations (38%, 95% CI 37.6‒38.3). Forty-four percent (44.5%, 95% CI 43.9‒45.0) of individuals utilized ambulance services. ED presentations, hospitalization for any reason, and unplanned hospitalizations were more common in individuals receiving HCP levels 3‒4 compared with those accessing HCP levels 1‒2. CONCLUSIONS AND IMPLICATIONS: HCP recipients in Australia have frequent hospitalizations, including ED presentations. In addition, almost 1 in 5 access respite care and 16.7% transition to permanent residential care each year. As the population accessing HCP is increasing, adequate support for these individuals to live well at home and avoid health events that lead to hospitalizations are necessary.

Investigating the association between infertility and psychological distress using Australian Longitudinal Study on Women's Health (ALSWH).

Infertility affects millions of people globally. Although an estimated 1 in 6 couples in Australia are unable to conceive without medical intervention, little is known about the mental health impacts of infertility. This study investigated how infertility impacts the mental health of women. The study used nationally representative Australian Longitudinal Study on Women's Health (ALSWH) data. We analysed data from survey periods 2-8 conducted every three years between 2000 and 2018 for 6582 women born in 1973-78. We used a Generalised Equation Modelling (GEE) method to investigate the association of primary, secondary and resolved fertility status and psychological distress over time. Multiple measures were used to measure psychological distress: the (1) the mental health index subscale of the 36-item short form survey (SF-36), (2) the Center for Epidemiological Studies Depression Scale (CESD-10), (3) the Goldberg Anxiety and Depression Scale (GADanx) anxiety subscale; and a (4) composite psychological distress variable. About a third (30%) of women reported infertility at any of the survey rounds; a steady increase over 18 years from 1.7% at round 2 to 19.3% at round 8. Half of the women reporting primary or secondary infertility reported psychological distress, with the odds of having psychological distress was higher in women reporting primary (odds ratio (OR) 1.24, 95% confidence interval (CI) 1.06-1.45), secondary (OR 1.27, 95% CI 1.10-1.46) or resolved infertility (OR 1.15, 95% CI 1.05-1.26) compared to women reporting normal fertility status. Women with partners, underweight or higher BMI, smoking, and high-risk alcohol use had higher odds of psychological distress, whereas women in paid work had significantly lower odds of psychological distress (p < 0.001). Diabetes, high blood pressure, asthma, and other chronic physical illness were independently associated with higher odds of psychological distress. Infertility has a significant impact on mental health even after it is resolved. Frequent mental health assessment and a holistic approach to address the lifestyle factors should be undertaken during the treatment of infertility.

Medications use among women with dementia: a cohort study.

BACKGROUND: Older population with dementia use huge range of medications. In this study, we aimed to determine the prevalence of commonly used medications a year before and after first recorded dementia diagnosis among older Australian women. METHODS: The study utilized Australian Longitudinal Study on Women's Health (ALSWH) data from 2090 women with known dementia, linked with administrative health datasets. The Pharmaceutical Benefits Scheme (PBS) data provided detailed information about prescribed medications. We applied latent class analysis (LCA) to the post-dementia data to identify patterns of medication use. Logistic regression model was used to explore the impact of potential predictors for medication utilization. RESULTS: Antipsychotic use increased from 5% before dementia to 19% after dementia, while antidementia medication use increased from < 1 to 28%. There was a modest increase in benzodiazepines and antidepressants. Post-dementia, four distinct groups were identified using LCA (names based on probabilities of medications use) as: "High Psychotropic-Low Cardiovascular" (16% of the sample); "Moderate Psychotropic-High Cardiovascular" (12%); "Low Psychotropic-High Cardiovascular" (27%); and "Low Psychotropic-Low Cardiovascular" (45%). Living in Residential Aged Care (RAC) and frailty were associated with increased odds of being in the higher psychotropic use groups. CONCLUSIONS: Substantial utilization of psychotropic medications by older people with dementia indicates a need for a careful review of the use of these medications. Appropriate alternative approaches to the management of dementia should be practiced with a special focus on RAC residents with frailty.

Polypharmacy trajectories among older women with and without dementia: A longitudinal cohort study.

Background: Although multiple medications are often utilized to achieve optimal treatment outcomes, polypharmacy (use of five or more medications) among older population is associated with several detrimental effects. Trajectories of polypharmacy among older population over time has not been described. Objective: This study estimated polypharmacy prevalence and clusters of individuals with similar patterns of change in polypharmacy among a cohort of older Australian women with and without dementia. Method: Longitudinal prospective cohort data from the oldest birth cohort (1921-1926) of the Australian Longitudinal Study on women's Health (ALSWH) were analysed. Survey data were linked with Pharmaceutical Benefit Schemes (PBS) data to obtain information about the type and number of prescription medications for each year 2003-2015. Group based trajectory modelling was used to identify distinct trajectory groups, based on the presence of polypharmacy for each year of observation. Trajectories were named based on distinctive and meaningful subgroups that followed approximately the same developmental course and probability assignment rule. Generalized estimating equation was used to identify factors associated with polypharmacy. Results: A total of 10,372 women were eligible for the inclusion in the study. Prevalence of polypharmacy increased over time and reached as high as 71.19% and 71.29% in 2014 for women with and without dementia, respectively. Four distinct polypharmacy trajectories were identified: 'Consistent Polypharmacy' (55.88%);'Low Polypharmacy' (24.52%); 'Rapid Increasing Polypharmacy' (12.50%); and 'Moderate Polypharmacy' (7.12%). Dementia, Residential Aged Care (RAC), frailty and comorbid condition were the key drivers of polypharmacy in this cohort. Conclusion: The prevalence of polypharmacy among older women increased over time, with most women have a pattern of consistent polypharmacy or rapidly increasing polypharmacy. Appropriate, sustainable, and effective strategies for reducing medication use should be implemented for women as they age, and particularly for those with dementia and those in residential care.

Use of medication reviews among older women with dementia, 2003-2015: A longitudinal cohort study.

OBJECTIVE: To identify factors associated with incidence of medication reviews (MRs), particularly in women with dementia and in residential aged care (RAC). METHODS: Data from 10 359 women in the 1921-1926 cohort of the Australian Longitudinal Study on Women's Health were linked to Medicare Benefits Schedule data to identify MRs for each year from 2003 to 2015. RESULTS: Incidence of MR increased from 2003 to 2013 (age 87-92 years) when 37.1% of women with dementia had a MR compared to 19.8% of women without dementia. Adjusting for time and other factors, the odds of having a MR were higher for women with dementia (AOR = 1.18, 95% CI: 1.06-1.32) and women in RAC (AOR = 3.61, 95% CI: 3.28-3.98). CONCLUSIONS: Although higher in women with dementia and those in RAC, utilisation of MR was modest. System-level interventions may be required to ensure the use and benefits of MRs.
