Objectives To identify rates of potentially preventable complications for dementia patients compared with non-dementia patients. Design Retrospective cohort design using hospital discharge data for dementia patients, case matched on sex, age, comorbidity and surgical status on a 1 : 4 ratio to non-dementia patients. Setting Public hospital discharge data from the state of New South Wales, Australia for 2006/2007. Participants 426 276 overnight hospital episodes for patients aged 50 and above (census sample). Main outcome measures Rates of preventable complications, with episode-level risk adjustment for 12 complications that are known to be sensitive to nursing care. Results Controlling for age and comorbidities, surgical dementia patients had higher rates than non-dementia patients in seven of the 12 complications: urinary tract infections, pressure ulcers, delirium, pneumonia, physiological and metabolic derangement (all at p<0.0001), sepsis and failure to rescue (at p<0.05). Medical dementia patients also had higher rates of these complications than did non-dementia patients. The highest rates and highest relative risk for dementia patients compared with non-dementia patients, in both medical and surgical populations, were found in four common complications: urinary tract infections, pressure areas, pneumonia and delirium. Conclusions Compared with non-dementia patients, hospitalised dementia patients have higher rates of potentially preventable complications that might be responsive to nursing interventions.

Increased length of stay and high rates of adverse clinical events in hospitalised patients with dementia is stimulating interest and debate about which costs may be associated and potentially avoided within this population. A retrospective cohort study was designed to identify and compare estimated costs for older people in relation to hospital-acquired complications and dementia. Australia’s most populous state provided a census sample of 426,276 discharged overnight public hospital episodes for patients aged 50+ in the 2006–07 financial year. Four common hospital-acquired complications (urinary tract infections, pressure areas, pneumonia, and delirium) were risk-adjusted at the episode level. Extra costs were attributed to patient length of stay above the average for each patient’s Diagnosis Related Group, with separate identification of fixed and variable costs (all in Australian dollars). These four complications were found to be associated with 6.4% of the total estimated cost of hospital episodes for people over 50 (A$226million/A$3.5billion), and 24.7% of the estimated extra cost of above-average length of stay spent in hospital for older patients (A$226million/A$914million). Dementia patients were more likely than non-dementia patients to have complications (RR 2.5, p <0.001) and these complications comprised 22.0% of the extra costs (A$49million/A$226million), despite only accounting for 10.4% of the hospital episodes (44,488/426,276). For both dementia and non-dementia patients, the complications were associated with an eightfold increase in length of stay (813%, or 3.6 days/0.4 days) and doubled the increased estimated mean episode cost (199%, or A$16,403/A$8,240). Urinary tract infections, pressure areas, pneumonia and delirium are potentially preventable hospital-acquired complications. This study shows that they produce a burdensome financial cost and reveals that they are very important in understanding length of stay and costs in older and complex patients. Once a complication occurs, the cost is similar for people with and without dementia. However, they occur more often among dementia patients. Advances in models of care, nurse skill-mix and healthy work environments show promise in prevention of these complications for dementia and non-dementia patients.

Background: People with dementia may have adverse outcomes following periods of acute hospitalization. This study aimed to explore the effects of age upon hospitalization outcomes for patients with dementia in comparison to patients without dementia.Methods: Data extracted from the New South Wales Admitted Patient Care Database for people aged 50 years and over for the period July 2006 to June 2007 were linked to create person-based records relating to both single and multiple periods of hospitalization. This yielded nearly 409,000 multi-day periods of hospitalization relating to almost 253,000 persons. Using ICD-10-AM codes for dementia and other principal diagnoses, the relationship between age and hospitalization characteristics were examined for people with and without dementia.Results: Dementia was age-related, with 25% of patients aged 85 years and over having dementia compared with 0.9% of patients aged 50–54 years. People with dementia were more likely to be admitted for fractured femurs, lower respiratory tract infections, urinary tract infections and head injuries than people without dementia. Mean length of stay for admissions for people with dementia was 16.4 days and 8.9 days for those without dementia. People with dementia were more likely than those without to be re-admitted within three months for another multi-day stay. Mortality rates and transfers to nursing home care were higher for people with dementia than for people without dementia. These outcomes were more pronounced in younger people with dementia.Conclusion: Outcomes of hospitalization vary substantially for patients with dementia compared with patients without dementia and these differences are frequently most marked among patients aged under 65 years.

To identify outcomes of using health information technologies to support direct resident care in residential aged care homes, for residents, staff and services. In May 2022, a systematic search used CINAHL, Cochrane CRCT, MEDLINE, Proquest, PsychINFO and Scopus databases to locate papers published after 1990. Thematic analysis was used to synthesise extracted data. Results are reported using the Preferred Reporting Items for Systematic Review and Meta-analysis (PRISMA) statement. Of 3721 references imported for screening, 1017 duplicates were removed and 2609 excluded, leaving 95 papers for data extraction. The included articles were conducted in diverse residential care homes, and involved over 12,000 nurse, care assistant or resident participants. Thematic analysis identified a range of health information technologies were used for direct care in residential care settings, and outcomes focussed on acceptability, efficiency and success of implementation. Less frequent were outcomes focussed on residents and families, and the safety and quality-of-care delivery. Staff outcomes, focussed on the satisfaction of staff and usability of the system, dominate in research examining health information technology used for direct care in residential aged care homes. Outcomes examining the use of health information technology in delivering improvements in resident health, well-being, quality and safety was limited. There is a need to increase using quality and safety of resident care as outcome measures.
