Health service use in the older person with complex health needs.

Objective Effective health care for older people with complex health needs requires a diverse range of healthcare professionals working together. The Building Partnerships Framework of the New South Wales Agency for Clinical Innovation seeks to promote collaboration and integration among service providers. The aim of the present study was to inform implementation and evaluation of the Framework. Methods Data from the 45 and Up Study was linked with deaths and service data from hospitalisations and the Medicare Benefits Schedule (MBS). Participants with a hospitalisation for conditions representing 'geriatric syndrome' were allocated to a complex needs group; the remainder were allocated to a comparison group. Hospital admissions and MBS services use were modelled using log-linear Poisson regression. Results Multivariate analysis showed that the rate of hospitalisation in the 2 years following index admission for the complex needs group was 18% (95% confidence interval (CI) 1.12-1.24) greater than the comparison group and specialist physician attendance was 13% (95% CI 1.06 - 1.21) greater. The rate of general practitioner (GP) attendances was 2% (95% CI 0.97-1.07) greater in the complex needs group, but this was not statistically significant. Discussion The greater rates of hospitalisation and specialist service use, the absence of a similar finding for GP services and the prominence of the role of primary care in service integration literature, policy and strategy underscore the importance of careful planning, consultation and inclusiveness in the development and implementation of integrated care policy. What is known about the topic? Older people with complex health needs are significant consumers of primary and secondary health services and benefit from well-planned and coordinated care. What does this paper add? The findings presented here indicate that although hospitals and specialist physicians provide a significantly greater volume of services to people with complex health needs, GPs do not. Within the limitations of the present study, these findings can contribute to integrated care policy and strategy development and implementation. What are the implications for practitioners? Given the prominence of primary care in service integration literature, policy and strategy and the findings of the present study with regard to the relative level of GP involvement in the management of people with complex needs, careful policy implementation will be required to ensure GPs are able to contribute significantly to coordinated cooperation between health services.

Effect of resistance training during hemodialysis on circulating cytokines: a randomized controlled trial.

The purpose of this study was to evaluate the effect of a 12-week intradialytic progressive resistance training (PRT) regimen on circulating pro- and anti-inflammatory cytokines. Forty-nine patients (62.6 ± 14.2 years) were recruited from the outpatient hemodialysis unit of the St. George Public Hospital, Sydney, Australia. Patients were randomized to: PRT + usual care (n = 24) or usual care control (n = 25). The PRT group performed two sets of 10 exercises at high intensity using free-weights, 3 times per week for 12 weeks during dialysis, while the control group did not exercise. Tumor necrosis factor-alpha, interleukin-1b, interleukin-6 (IL-6), interleukin-8 (IL-8), interleukin-10, and interleukin-12 were measured in serum before and after the intervention period. Muscle cross-sectional area (CSA), intramuscular lipid, intermuscular adipose tissue, and subcutaneous and total thigh fat, evaluated via computed tomography of the non-dominant mid-thigh, were also collected at both time points. All cytokines were significantly elevated in the total cohort at baseline compared with normative data. There were no cytokine changes over time or between groups (p > 0.05). In secondary analyses pooling the groups, changes in logIL-6 and IL-8 were inversely related to changes subcutaneous thigh fat (p < 0.05) while changes in logIL-6 were also inversely related to changes in thigh muscle CSA, and total thigh fat (p < 0.03). These data suggest that 12 weeks of intradialytic progressive resistance training does not improve circulating pro- and anti-inflammatory markers. Further research is required to elucidate the implications and mechanisms of the relationships between IL-6 and IL-8 and body composition in ESRD.
