Optimal antiseptic skin preparation agents for minimizing surgical site infection following surgery: cost and cost-effectiveness analysis.

BACKGROUND: The application of antiseptic skin agents prior to incision minimizes the rate of surgical site infection. Despite their ubiquity, the optimal skin preparation agent remains uncertain. A retrospective economic analysis was conducted to complement the results from the NEWSkin Prep trial which prospectively compared three preparation agents. METHODS: A cost and cost-effectiveness analysis was performed from a healthcare service perspective to compare chlorhexidine with 70% ethanol, and aqueous povidone-iodine, against povidone-iodine with 70% ethanol. Resource use estimates accounted for hospital admissions, readmissions associated with surgical site infection, outpatient and general practitioner attendances, visits from community nurses and therapeutic consumables. The measure of effectiveness comprised the net difference in number of patients with surgical site infections per 1000 patients. Costs were compared using a two-sample Welch's t-test. Deterministic and probabilistic sensitivity analyses were performed to evaluate the incremental cost-effectiveness ratio. RESULTS: The null hypothesis that the mean costs for the trial arms were significantly different was not rejected (Welch's t-test P value: 0.771 for chlorhexidine with 70% ethanol against povidone-iodine with 70% ethanol; and 0.955 for aqueous povidone-iodine against povidone-iodine with 70% ethanol). Based on bootstrap averages, the chlorhexidine with 70% ethanol intervention generated 8.0 fewer surgical site infections per 1000 patients and net cost savings of €151,698 (Euros) per 1000 patients compared with povidone-iodine with 70% ethanol, and aqueous povidone-iodine produced a net cost saving of €37,494 per 1000 patients but generated an additional 11.6 surgical site infections per 1000 patients compared with povidone-iodine with 70% ethanol. The comparison of chlorhexidine with 70% ethanol to povidone-iodine with 70% ethanol was sensitive to the inclusion of cost outliers, while the comparison of aqueous povidone-iodine to povidone-iodine with 70% ethanol was sensitive to the estimated cost per surgical site infection. CONCLUSION: Based on the outcomes from the NEWSkin Prep study, this economic analysis found no definitive evidence in favour of any one of the study comparators. Future model-based economic analyses of alternative skin preparations should critically address the quality of evidence and integrate the results from the NEWSkin Prep study.

Differences in Falls and Physical Activity in Older Women From Two Generations.

BACKGROUND: Falls and physical inactivity increase with age. However, physical activity, falls and their associations in older people born at different times are unclear. METHODS: Women born 1921-26 and 1946-51 who completed follow-up questionnaires in 1999 (n = 8 403, mean (SD) age: 75 (1) years) and 2019 (n = 7 555; 71 (1) years) in the Australian Longitudinal Study on Women's Health. Self-reported noninjurious and injurious falls in the previous 12 months and weekly amounts and types of physical activity (brisk walking, moderate- and vigorous-intensity) were compared between the cohorts using Chi-square tests. Associations between physical activity, and noninjurious and injurious falls were estimated using multinomial logistic regressions informed by a directed acyclic graph. RESULTS: A greater proportion of the later (1946-51) cohort (59%) reached 150-300 minutes of weekly physical activity, as recommended by the World Health Organization, compared to the earlier (1921-26) cohort (43%, p < .001). A greater proportion of the later cohort reported noninjurious falls (14% vs 8%). Both cohorts reported similar proportions of injurious falls (1946-51:15%, 1921-26:14%). In both cohorts, participation in 150-300 minutes of physical activity was associated with lower odds of noninjurious falls (adjusted Odds Ratio, 95% CI: 1921-26: 0.66, 0.52-0.84; 1946-51: 0.78, 0.63-0.97) and injurious falls (1921-26: 0.72, 0.60-0.87; 1946-51: 0.78, 0.64-0.96). CONCLUSIONS: Participation in recommended levels of physical activity was associated with reduced falls in both cohorts. However, generational differences were found with more falls and more physical activities in the women born later. Future studies could examine the reasons contributing to the generational differences.

Leisure-Time Physical Activity and Falls With and Without Injuries Among Older Adult Women.

Importance: Falls and fall-related injuries are common among older adults. Older adults are recommended to undertake 150 to 300 minutes of physical activity per week for health benefits; however, the association between meeting the recommended level of physical activity and falls is unclear. Objectives: To examine whether associations exist between leisure-time physical activity and noninjurious and injurious falls in older women. Design, Setting, and Participants: This population-based cohort study used a retrospective analysis of the Australian Longitudinal Study on Women's Health (ALSWH). ALSWH participants born from 1946 to 1951 who completed follow-up questionnaires in 2016 (aged 65-70 years) and 2019 (aged 68-73 years) were included. Statistical analysis was performed from September 2022 to February 2023. Exposure: Self-reported weekly amounts (0, 1 to <150, 150 to <300, ≥300 minutes) and types of leisure-time physical activity, including brisk walking and moderate- and vigorous-intensity physical activity, in the 2016 survey. Main outcome and measures: Noninjurious and injurious falls in the previous 12 months reported in the 2019 survey. Associations between leisure-time physical activity and falls were quantified using directed acyclic graph-informed multinomial logistic regression and presented in odds ratios (ORs) and 95% CIs. Results: This study included 7139 women (mean [SD] age, 67.7 [1.5] years). Participation in leisure-time physical activity at or above the level recommended by the World Health Organization (150 to <300 min/wk) was associated with reduced odds of noninjurious falls (150 to <300 min/wk: OR, 0.74 [95% CI, 0.59-0.92]; ≥300 min/wk: OR, 0.66 [95% CI, 0.54-0.80]) and injurious falls (150 to <300 min/wk: OR, 0.70 [95% CI, 0.56-0.88]; ≥300 min/wk: OR, 0.77 [95% CI, 0.63-0.93]). Compared with women who reported no leisure-time physical activity, those who reported brisk walking (OR, 0.83 [95% CI, 0.70-0.97]), moderate leisure-time physical activity (OR, 0.81 [95% CI, 0.70-0.93]), or moderate-vigorous leisure-time physical activity (OR, 0.84 [95% CI, 0.70-0.99]) had reduced odds of noninjurious falls. No statistically significant associations were found between the types of leisure-time physical activity and injurious falls. Conclusions and Relevance: Participation in leisure-time physical activity at the recommended level or above was associated with lower odds of both noninjurious and injurious falls. Brisk walking and both moderate and moderate-vigorous leisure-time physical activity were associated with lower odds of noninjurious falls.

Mental health service use and cost by Australian women in metropolitan and rural areas.

INTRODUCTION: The use and costs of mental health services by rural and remote Australian women are poorly understood. OBJECTIVE: To examine the use of the Better Access Scheme (BAS) mental health services across geographical areas. DESIGN: Observational epidemiology cohort study using a nationally representative sample of 14 247 women from the Australian Longitudinal Study on Women's Health born 1973-1978, linked to the Medical Benefits Schedule dataset for use of BAS services from 2006 to 2015. The number and cost of BAS services were compared across metropolitan and regional/remote areas for women using the mental health services. FINDINGS: 31% of women accessed a BAS mental health service, 12% in rural populations. Overall, 90% of women with estimated high service need had contact with professional services (83% rural vs 92% metropolitan regions). Mean mental health scores were lower for women accessing a BAS service in remote areas compared with metropolitan, inner and outer regional areas (61.9 vs 65.7 vs 64.8 vs 64.2, respectively). Higher proportion of women in remote areas who were smokers, low/risky drinkers and underweight were more likely to seek treatment. Compared with metropolitan areas, women in inner, outer regional and remote areas accessed a lower mean number of services in the first year of diagnosis (6.0 vs 5.0 vs 4.1 vs 4.2, respectively). Actual mean overall annual costs of services in the first year of diagnosis were higher for women in metropolitan areas compared with inner, outer regional or remote areas ($733.56 vs $542.17 vs $444.00 vs $459.85, respectively). DISCUSSION: Women in rural/remote areas not accessing services need to be identified, especially among those with the highest levels of distress. In remote areas, women had greater needs when accessing services, although a substantial proportion of women who sought help through the BAS services lived in metropolitan areas. CONCLUSION: Regardless of lower cost to services in rural/remote areas, geographic and economic barriers may still be major obstacles to accessing services.

Longitudinal analysis of the Alternative Healthy Eating Index-2010 and incident non-communicable diseases over 15 years in the 1973-1978 cohort of the Australian Longitudinal Study on Women's Health.

In studies that contain repeated measures of variables, longitudinal analysis accounting for time-varying covariates is one of the options. We aimed to explore longitudinal association between diet quality (DQ) and non-communicable diseases (NCDs). Participants from the 1973-1978 cohort of the Australian Longitudinal Study on Women's Health (ALSWH) were included, if they; responded to survey 3 (S3, 2003, aged 25-30 years) and at least one survey between survey 4 (S4, 2006) and survey 8 (S8, 2018), were free of NCDs at or before S3, and provided dietary data at S3 or S5. Outcomes were coronary heart disease (CHD), hypertension (HT), asthma, cancer (except skin cancer), diabetes mellitus (DM), depression and/or anxiety, and multimorbidity (MM). Longitudinal modelling using generalised estimation equation (GEE) approach with time-invariant (S4), time-varying (S4-S8) and lagged (S3-S7) covariates were performed. The mean (± standard deviation) of Alternative Healthy Eating Index-2010 (AHEI-2010) of participants (n = 8022) was 51·6 ± 11·0 (range: 19-91). Compared to women with the lowest DQ (AHEI-2010 quintile 1), those in quintile 5 had reduced odds of NCDs in time-invariant model (asthma: OR (95 % CI): 0·77 (0·62-0·96), time-varying model (HT: 0·71 (0·50-0·99); asthma: 0·62 (0·51-0·76); and MM: 0·75 (0·58-0·97) and lagged model (HT: 0·67 (0·49-0·91); and asthma: 0·70 (0·57-0·85). Temporal associations between diet and some NCDs were more prominent in lagged GEE analyses. Evidence of diet as NCD prevention in women aged 25-45 years is evolving, and more studies that consider different longitudinal analyses are needed.

Lactate dehydrogenase contribution to symptom persistence in long COVID: A pooled analysis.

There's critical need for risk predictors in long COVID. This meta-analysis evaluates the evidence for an association between plasma lactate dehydrogenase (LDH) and long COVID and explores the contribution of LDH to symptoms persistent across the distinct post-acute sequelae of COVID-19 (PASC) domains. PubMed, EMBASE, Web of Science, and Google Scholar were searched for articles published up to 20 March 2023 for studies that reported data on LDH levels in COVID-19 survivors with and without PASC. Random-effect meta-analysis was employed to estimate the standardized mean difference (SMD) with corresponding 95% confidence interval of each outcome. There were a total of 8289 study participants (3338 PASC vs. 4951 controls) from 46 studies. Our meta-analysis compared to the controls showed a significant association between LDH elevation and Resp-PASC [SMD = 1.07, 95%CI = 0.72, 1.41, p = 0.01] but not Cardio-PASC [SMD = 1.79, 95%CI = -0.02, 3.61, p = 0.05], Neuro-PASC [SMD = 0.19, 95%CI = -0.24, 0.61, p = 0.40], and Gastrointestinal-PASC [SMD = 0.45, 95%CI = -1.08, 1.98, p = 0.56]. This meta-analysis suggests elevated LDH can be used for predicting Resp-PASC, but not Cardio-PASC, Neuro-PASC or gastrointestinal-PASC. Thus, elevated plasma LDH following COVID infection may be considered as a disease biomarker.

Validation of Frail Scale and comparison with hospital frailty risk score to predict hospital use in a cohort of older Australian women.

INTRODUCTION: With no standard frailty tool for clinical care, research and policymaking, identifying frail older people is a challenge. AIMS: This study aimed to compare two validated scales, which are the Frail Scale and Hospital Frailty Risk Score (HFRS) for their ability in identifying frailty in older Australian women and predicting hospital use. METHODS: This study included older Australian women aged 75-95 years, who had unplanned overnight hospital admission as an index admission between 2001 and 2016. Data from the Australian Longitudinal Study on Women's Health (ALSWH) were linked with administrative hospital data to calculate HFRS (using the International Statistical Classification of Diseases, Australia Modification (ICD-10-AM) diagnostic codes) and the Frail Scale (using the ALSWH self-reported survey). RESULTS: The Frail Scale identified a higher proportion of older frail women (30.54%) compared to the HFRS (23.0%). Frail older women, classified by Frail Scale, were at higher risk of long hospital stay (adjusted odds ratio = 1.28, 95% CI = 1.02-1.60), repeated admission (adjusted hazard ratio [AHR] = 1.30, 95% CI = 1.03-1.41) and death (AHR = 1.70, 95% CI = 1.45-2.01). HFRS was associated with longer hospital stay and mortality. CONCLUSIONS: The proportion of older women classified as frail by the Frail Scale tool was higher than women classified as frail by HFRS. The Frail Scale and HFRS were not significantly associated with each other. While both tools were associated with the risk of long hospital stay and mortality, only the Frail Scale predicted the risk of repeated admission.

A systematic review and meta-analysis of long-term sequelae of COVID-19 2-year after SARS-CoV-2 infection: A call to action for neurological, physical, and psychological sciences.

Long-term sequelae conditions of COVID-19 at least 2-year following SARS-CoV-2 infection are unclear and little is known about their prevalence, longitudinal trajectory, and potential risk factors. Therefore, we conducted a comprehensive meta-analysis of survivors' health-related consequences and sequelae at 2-year following SARS-CoV-2 infection. PubMed/MEDLINE, CENTRAL, and EMBASE were systematically searched up to February 10, 2023. A systematic review and meta-analysis were performed to calculate the pooled effect size, expressed as event rate (ER) with corresponding 95% confidence interval (CI) of each outcome. Twelve studies involving 1 289 044 participants from 11 countries were included. A total of 41.7% of COVID-19 survivors experienced at least one unresolved symptom and 14.1% were unable to return to work at 2-year after SARS-CoV-2 infection. The most frequent symptoms and investigated findings at 2-year after SARS-CoV-2 infection were fatigue (27.4%; 95% CI 17%-40.9%), sleep difficulties (25.1%; 95% CI 22.4%-27.9%), impaired diffusion capacity for carbon monoxide (24.6%; 95% CI 10.8%-46.9%), hair loss (10.2%; 95% CI 7.3%-14.2%), and dyspnea (10.1%; 95% CI 4.3%-21.9%). Individuals with severe infection suffered more from anxiety (OR = 1.69, 95% CI 1.17-2.44) and had more impairments in forced vital capacity (OR = 9.70, 95% CI 1.94-48.41), total lung capacity (OR = 3.51, 95% CI 1.77-6.99), and residual volume (OR = 3.35, 95% CI 1.85-6.07) after recovery. Existing evidence suggest that participants with a higher risk of long-term sequelae were older, mostly female, had pre-existing medical comorbidities, with more severe status, underwent corticosteroid therapy, and higher inflammation at acute infection. Our findings suggest that 2-year after recovery from SARS-CoV-2 infection, 41.7% of survivors still suffer from either neurological, physical, and psychological sequela. These findings indicate that there is an urgent need to preclude persistent or emerging long-term sequelae and provide intervention strategies to reduce the risk of long COVID.

Physical activity and injurious falls in older Australian women: adjusted associations and modification by physical function limitation and frailty in the Australian Longitudinal Study on Women's Health.

OBJECTIVES: To investigate associations between leisure-time physical activity (LPA) and injurious falls in older women and explore modification of associations by physical function and frailty. METHODS: Women born during 1946-51 from the Australian Longitudinal Study on Women's Health, injurious falls (self-reported fall with injury and/or medical attention) and self-reported weekly LPA (duration and type). We undertook cross-sectional and prospective analyses using data from 2016 [n = 8,171, mean (SD) age 68 (1)] and 2019 surveys (n = 7,057). Associations were quantified using directed acyclic graph-informed logistic regression and effect modification examined using product terms. RESULTS: Participation in LPA as recommended by World Health Organization (150-300 min/week) was associated with lower odds of injurious falls in cross-sectional (adjusted Odds Ratio (OR) 0.74, 95% CI 0.61-0.90) and prospective analyses (OR 0.75, 95% CI 0.60-0.94). Compared with those who reported no LPA, cross-sectionally, odds of injurious falls were lower in those who reported brisk walking (OR 0.77, 95% CI 0.67-0.89) and vigorous LPA (OR 0.86, 95% CI 0.75-1.00). No significant association was found between different types of LPA and injurious falls prospectively. Only cross-sectionally, physical function limitation and frailty modified the association between LPA and injurious falls, with tendencies for more injurious falls with more activity in those with physical limitation or frailty, and fewer injurious falls with more activity among those without physical function limitation or frailty. CONCLUSION: Participation in recommended levels of LPA was associated with lower odds of injurious falls. Caution is required when promoting general physical activity among people with physical limitation or frailty.

A longitudinal analysis of factors associated with age-related cataract among older Australian women: a cohort study of 7851 older Australian women 79-90 years.

BACKGROUND: Age-related cataracts are a significant global health issue due to population ageing. More than 70% of older Australians aged 80 or above have clinically significant age-related cataracts. AIM: The study aimed to identify factors associated with age-related cataracts among older Australian women 79-90 years. METHOD: A 6-year longitudinal analysis of the Australian Longitudinal Study on Women's Health (ALSWH) was conducted on 7117 women from surveys four to six. The women were asked whether they had been diagnosed or treated for cataracts 3 years before each survey. We used generalised estimating equation (GEE) modelling to identify factors independently associated with age-related cataracts. RESULTS: At baseline (79-84 years), 44.8% lived in metropolitan Australia, 67.9% had good general health, 26.5% had private health insurance, 30.6% had cataracts, 28.8% had undergone cataract surgery, 12.0% had diabetes, 24.9% had skin cancer, 56.2% had hypertension, 24.0% had a history of falls, 63.0% had visited general practitioner (GP) frequently, and 48.8% were driving themselves as their main means of transport. In the final model, poor general health [adjusted odds ratio (AOR) = 1.23, 95% CI = 1.14, 1.33)], not driving (AOR = 1.09, 95% CI = 1.01, 1.18), having private health insurance (AOR = 1.13, 95% CI = 1.04, 1.23), frequent GP visits (AOR = 1.16, 95% CI = 1.07, 1.25), skin cancer (AOR = 1.26, 95% CI = 1.16, 1.37), hypertension (AOR = 1.13, 95% CI = 1.05, 1.21), and fall (AOR = 1.12, 95% CI = 1.04, 1.22) were significantly associated with the age-related cataracts. CONCLUSIONS: Systemic diseases, poor quality of life, driving cessation, and health service use were significantly associated with age-related cataracts in older women.

Fall-related health service use in Stepping On programme participants and matched controls: a non-randomised observational trial within the 45 and Up Study.

BACKGROUND: Falls and fall-related health service use among older adults continue to increase. The New South Wales Health Department, Australia, is delivering the Stepping On fall prevention programme at scale. We compared fall-related health service use in Stepping On participants and matched controls. METHODS: A non-randomised observational trial was undertaken using 45 and Up Study data. 45 and Up Study participants who did and did not participate in Stepping On were extracted in a 1:4 ratio. Rates of fall-related health service use from linked routinely collected data were compared between participants and controls over time using multilevel Poisson regression models with adjustment for the minimally sufficient set of confounders identified from a directed acyclic graph. RESULTS: Data from 1,452 Stepping On participants and 5,799 controls were analysed. Health service use increased over time and was greater in Stepping On participants (rate ratios (RRs) 1.47-1.82) with a spike in use in the 6 months prior to programme participation. Significant interactions indicated differential patterns of health service use in participants and controls: stratified analyses revealed less fall-related health service use in participants post-programme compared to pre-programme (RRs 0.32-0.48), but no change in controls' health service use (RRs 1.00-1.25). Gender was identified to be a significant effect modifier for health service use (P < 0.05 for interaction). DISCUSSION: Stepping On appeared to mitigate participants' rising fall-related health service use. Best practice methods were used to maximise this study's validity, but cautious interpretation of results is required given its non-randomised nature.

Tailoring childhood immunisation services in a socioeconomically disadvantaged community in New South Wales, Australia: a cost analysis.

BACKGROUND: Using the World Health Organization's 'Guide to Tailoring Immunization Programmes' (TIP), a three-step program was developed by health services in partnership with a marginalised community in New South Wales, Australia. The aim was to improve immunisation rates of 1-year-old children. For Step 1, nurses identified and monitored local children overdue for immunisation from a national register, and sent parents or family doctors reminders by mail or telephone. For Step 2, parents were offered appointments at a local health centre; and for Step 3, they were offered home visits. METHODS: An economic costing study was undertaken to examine the program's resource use. Costs were collected between 1 June 2020 and 31 May 2021. Case records were obtained for 139 children. RESULTS: A total of 56 children became up to date after receiving TIP services; most after receiving Step 1 services (n =37). Total annual costs (A$) for the program were $34250 or $246 per case; or $612 per case becoming up to date. At $44 per case and $98 per case becoming up to date, Step 1B: personalised reminders, was the lowest costing step. Sensitivity analysis showed a possible 8% program savings through employment of nurses with a lower salary and use of video conference meetings. CONCLUSION: This study provides information to the local health provider on the cost of TIP alongside their community-based programs. It also identified ways in which TIP could be made more cost-effective. Decision-makers can use this information to consider whether the investment in TIP is recommended.

Alternative Healthy Eating Index-2010 and Incident Non-Communicable Diseases: Findings from a 15-Year Follow Up of Women from the 1973-78 Cohort of the Australian Longitudinal Study on Women's Health.

Non-communicable diseases (NCDs) and multimorbidity (≥two chronic conditions), are increasing globally. Diet is a risk factor for some NCDs. We aimed to investigate the association between diet quality (DQ) and incident NCDs. Participants were from the Australian Longitudinal Study on Women's Health 1973-78 cohort with no NCD and completed dietary data at survey 3 (2003, aged 25-30 years) who responded to at least one survey between survey 4 (2006) and survey 8 (2018). DQ was measured by the Alternative Healthy Eating Index-2010 (AHEI-2010). Outcomes included coronary heart disease (CHD), hypertension (HT), asthma, cancer (excluding skin cancer), diabetes mellitus (DM), depression and/or anxiety, multimorbidity, and all-cause mortality. Repeated cross-sectional multivariate logistic regressions were performed to investigate the association between baseline DQ and NCDs over 15 years. The AHEI-2010 mean (±sd) for participants (n = 8017) was 51.6 ± 11.0 (range: 19-91). There was an inverse association between AHEI-2010 and incident asthma at survey 4 (ORQ5-Q1: 0.75, 95% CI: 0.57, 0.99). Baseline DQ did not predict the occurrence of any NCDs or multimorbidity between the ages of 25-45 years. Further well-planned, large prospective studies conducted in young women are needed to explore dietary risk factors before the establishment of NCDs.

Understanding the relationship between eye disease and driving in very old Australian women: a longitudinal thematic evaluation.

BACKGROUND: Over recent decades an increasing number of adults will retain their driver's licenses well into their later years. The aim of this study was to understand and explore the experience of driving and driving cessation in very old Australian women with self-reported eye disease. METHODS: An interpretative qualitative study. Participants were from the Australian Longitudinal Study on Women's Health (cohort born in 1921-26), a sample broadly representative of similarly aged Australian women. Responses to open-ended questions were analysed using an inductive thematic approach, employing a process of constant comparison. RESULTS: Qualitative data were from 216 older women with eye disease who made 2199 comments about driving, aged between 70 and 90 years depending on the timing of their comments. Themes included: (1) Access to treatment for eye disease promotes driving independence and quality of life; (2) Driving with restrictions for eye disease enables community engagement and (3) Driving cessation due to poor vision leads to significant lifestyle changes. CONCLUSIONS: Key findings highlighted driving cessation, or reduction, is often attributed to deterioration in vision. The consequence is dependence on others for transport, typically children and friends. Access to successful treatment for eye disease allowed older women to continue driving. We posit that occupational therapists can play an essential role in promote driving confidence and ability as women age. TRIAL REGISTRATION: Not applicable.

Transitions in health service use among women with poor mental health: a 7-year follow-up.

OBJECTIVE: Women suffering from mental health problems require varied needs of mental health service utilisation. Transition between general practitioner and mental health services use are available through the Better Access Scheme initiative, for those in need of treatment. The study's aim was to identify trajectories of mental health service utilisation by Australian women. DESIGN: The Australian Longitudinal Study on Women's Health data linked to the administrative medical claims dataset were used to identify subgroups of women profiled by their mental health service use from 2006 to 2013. Latent growth mixture model is a statistical method to profile subgroups of individuals based on their responses to a set of observed variables allowing for changes over time. Latent class groups were identified, and used to examine predisposing factors associated with patterns of mental health service use change over time. SETTING: This study was conducted in Australia. PARTICIPANTS: National representative sample of women of born in 1973-1978, who were aged between 28 and 33 years at the start of our study period. RESULTS: Six latent class trajectories of women's mental health service use were identified over the period 2006-2013. Approximately, one-quarter of the sample were classified as the most recent users, while approximate equal proportions were identified as either early users, late/low user or late-high users. Additional, subgroups were defined as the consistent-reduced user and the late-high users, over time. Only 7.2% of the sample was classified as consistent high users who potentially used the services each year. CONCLUSION: These findings suggest that use of the Better Access Scheme mental health services through primary care was varied over time and may be tailored to each individual's needs for the treatment of depressive symptoms.

Patterns of health service use before and after a statewide fall prevention initiative for older adults at risk of falls.

OBJECTIVE: To understand health-care burden from fall-related injury, we investigated patterns of health service use in participants of the Australian statewide Stepping On fall prevention program. METHODS: Routinely collected ambulance, emergency, hospital and mortality data for 9163 participants across NSW Local Health Districts between 2009 and 2015 were analysed for patterns in fall-related health service use three years before and after the Stepping On program using negative binomial regression analyses. RESULTS: Overall fall-related health service use increased over the 6-year study period. There was a high period of usage prior to program participation, which decreased postprogram, then appeared to increase again after 12-15 months. Subgroup analysis showed strongest postprogram reductions for women. CONCLUSIONS: Patterns of service usage suggest initial program benefits that taper off over time. The results of this observational study need to be interpreted with caution. Investment in ongoing fall prevention programs may be needed for lasting impacts.

Application of Andersen-Newman model to assess cataract surgery uptake among older Australian women: findings from the Australian Longitudinal Study on Women's Health (ALSWH).

INTRODUCTION: Although Cataract Surgery Rate is increasing, the availability of surgery is outstripped by the increasing number of cataract cases as populations age. AIM: The study aimed to identify factors associated with cataract surgery uptake in terms of predisposing, enabling, and need factors in very old Australian women. METHOD: This study used ALSWH data included 6229 women aged 79-84 to 85-90 years. Women were asked whether they had undergone eye surgery (including cataracts) three years prior to each survey. Generalised estimating equation modelling was used to determine factors associated with these surgeries. RESULT: At baseline (2005), more than half of the participants either had undergone surgery (43.5%) or had unoperated cataracts (7.6%). Increasing age (AOR = 1.11, 95% CI = 1.07, 1.15) and being current or ex-smokers (AOR = 1.15, 95% CI = 1.03, 1.29) were associated with higher odds of cataract surgery (predisposing factors). Women who had private health insurance had 27% higher odds of having surgery (AOR = 1.27, 95% CI = 1.16, 1.39) (enabling factor). Need factors of more General Practitioner visits (AOR = 1.16, 95% CI = 1.09, 1.25) and skin cancer (AOR = 1.09, 95% CI = 1.01, 1.17) also increased the odds of cataract surgery. Women who had no difficulty seeing newspaper print were more likely to have had cataract surgery (AOR = 1.35, 95% CI = 1.23, 1.48). CONCLUSION: Need factors are the major drivers of cataract surgery; however, predisposing and enabling factors also play a role, including access to private health insurance. This finding indicates some inequity regarding access to cataract surgery in the Australian setting.

Determinants of driving among oldest-old Australian women.

This study examined predictors of driving among oldest-old Australian women in their late 80s in accordance with the World Health Organization's healthy aging framework. The study used data from the 1921-26 cohort of the Australian Longitudinal Study on Women's Health, wave-6 (n = 4025). The result of the multivariable logistic regression showed providing care, living alone, volunteering, living in rural/outer regional Australia, having higher educational attainment, and social interactions were associated with driving. The findings indicate driving should not be dismissed based on age alone. Policymakers need to also consider social roles, driving environment and context with the goals of healthy aging.
