Implications of decreasing surgical lengths of stay.

A recent study at the Prince of Wales Hospital (PoW) compared health outcomes and user satisfaction for conventional clinical pathways with a shortened pathway incorporating day of surgery admission (DOSA), early discharge and post acute care domiciliary visits for two high volume, elective surgical procedures (herniorrhaphy and laparoscopic cholecystectomy). This paper quantifies cost differences between the control and intervention groups for nursing salaries and wages, other ward costs, pathology and imaging. The study verified and measured the lower resource use that accompanies a significant reduction in length of stay (LOS). Costs of pre- and post-operative domiciliary visits were calculated and offset against savings generated by the re-engineered clinical pathway. Average costs per separation were at least $239 (herniorrhaphy) and $265 (laparoscopic cholecystectomy) lower for those on the DOSA pathway with domiciliary post acute care.

A randomised controlled trial of the costs of hospital as compared with hospital in the home for acute medical patients.

OBJECTIVE: To test the cost effectiveness of Hospital in the Home compared to hospital admission for acute medical conditions. METHOD: Randomised controlled trial at the Prince of Wales Hospital, Sydney, from October 1995 to February, 1997; 100 patients with acute medical conditions admitted through the Emergency Department. RESULTS: The Hospital in the Home (HITH) group costs per separation ($1,764, CI 95% $1,416-$2,111, n = 50) were significantly lower (p < 0.0001, Mann-Whitney U-Wilcoxon Rank Sum) than the control group hospital separation ($3,614, CI 95% $2,881.37-$4,347.27, n = 47) with no significant difference in clinical outcomes, and comparable or better user satisfaction. CONCLUSION: Given the favourable clinical outcomes the HITH model produces at a lower cost, the cost-effectiveness of the care mode is high, and the allocative efficiency favourable. IMPLICATIONS: As a care model and critical pathway, HITH offers hospitals real bed day savings that can either be used to rationalise resource usage for a given level of activity, or increase throughput.

Use of pathology services in re-engineered clinical pathways.

A significant proportion of pathology tests ordered in hospital are unnecessary. Specific measures targeting the increasing appropriateness of pathology service use have been shown to decrease overall ordering of laboratory tests. However, it is not clear whether general programmes to improve quality of care will have any impact on the use of pathology services. Use of pathology services was compared within two separate prospective controlled clinical trials of re-engineered clinical pathways for both elective (surgical) patients and acute unplanned (medical) admissions. Trial One was a controlled trial of a re-engineered surgical service. Booked patients in the treatment group were admitted on the day of surgery, care was guided by a clinical pathway, and patients were discharged early with domiciliary post-acute care. Controls were admitted on the day before surgery, treated according to usual practice and discharged according to surgeons' preferences. In Trial Two, acute medical patients admitted to hospital through the Emergency Department (ED) were randomised into a treatment (Hospital in the Home) or a control (inpatient) care pathway. In both studies, patients on the re-engineered clinical pathways were well matched demographically and clinically. Health outcomes and satisfaction ratings were comparable. Seventy per cent fewer laboratory tests were ordered in the elective surgery intervention group (P < 0.0001), while the treatment group of the acute medical patients had 25% fewer tests ordered (P = 0.0133). Pooled results also showed a significantly lower rate of test ordering (P < 0.001) for the treatment group (Mann-Whitney U-Wilcoxon ranked sum test). The findings of these audits of controlled, prospective trials suggested overuse of laboratory tests in New South Wales public hospitals, and that savings can be generated by using clinical pathways and applying clinical criteria to the ordering of tests without adversely affecting health outcomes.

Decreasing lengths of stay: the cost to the community.

BACKGROUND: Patients who are discharged earlier from hospital frequently require support from professional and unpaid carers at home after discharge. Hospitals save money per patient by discharging earlier, but it is not known whether the costs to community services and unpaid caters outweigh the savings to the hospital. METHODS: We prospectively studied the total costs, patient satisfaction, time off work and pain scores of 224 patients who underwent elective herniorrhaphy or laparoscopic cholecystectomy and who lived locally before and after re-engineering the elective surgical service. The components of the re-engineered surgical service were a peri-operative unit, pre-admission anaesthetic assessment based on self-reported questionnaires, day of surgery admissions, enhanced patient education, clinical pathways, and post-acute care. RESULTS: The patients treated through the re-engineered surgical service had a significantly shorter length of stay (LOS) (mean LOS: 2.2 vs 3.2 days; P < 0.001) but neither they nor their carers required more time off work. Significant determinants of time off work were smoking, heavy lifting at work and a higher pain score at day 7. Patients treated through the re-engineered surgical service recorded significantly higher satisfaction with their treatment. The cost saving to the hospital outweighed the cost of increased services provided in the community, so that the overall cost of providing treatment was over $200 less per patient through the re-engineered service. CONCLUSIONS: This study demonstrates that changes in care provision that result in shorter LOS and greater cost effectiveness may better meet patients' needs than existing systems.

Hospital in the home: a randomised controlled trial.

OBJECTIVES: To compare treatment of acute illness at home and in hospital, assessing safety, effect on geriatric complications, and patient/carer satisfaction. DESIGN: Randomised controlled trial. SETTING: A tertiary referral hospital affiliated with the University of New South Wales. PARTICIPANTS: 100 patients (69% older than 65 years) with a variety of acute conditions, who were assessed in the emergency department as requiring admission to hospital. INTERVENTIONS: Patients were allocated at random to be treated by a hospital-in-the-home (HIH) service in their usual residence or to be admitted to hospital. MAIN OUTCOME MEASURES: Geriatric complications (confusion, falls, urinary incontinence or retention, faecal incontinence or constipation, phlebitis and pressure areas), patient/carer satisfaction, adverse events, and death. RESULTS: There was a lower incidence of confusion (0 v. 20.4% [95% CI, 9.1%-31.7%]; P = 0.0005), urinary complications (incontinence or retention) (2.0% [95% CI, -1.8%, 5.8%] v. 16.3% [95% CI, 6.0%, 26.6%]; P = 0.01), and bowel complications (incontinence or constipation) (0 v. 22.5% [95% CI, 10.7%, 34.1%]; P = 0.0003) among HIH-treated patients. No significant difference in number of adverse events and deaths (to 28 days after discharge) in the two groups was found (although numbers were small). Patient and carer satisfaction was significantly higher in the HIH group. CONCLUSIONS: Home treatment appears to provide a safe alternative to hospitalisation for selected patients, and may be preferable for some older patients. We found high levels of both patient and carer satisfaction with home treatment.
