Article: Medical Assessment Units and the older patient: a retrospective case-control study.
[show abstract] [hide abstract]
ABSTRACT: To evaluate the effect of a Medical Assessment Unit (MAU) on older patients. Retrospective case-control study of patients 65 years and above admitted to the MAU (study group) and the general medical wards (control group) in Bankstown-Lidcombe Hospital from 1 October 2008 to 31 March 2009 with four most common Diagnosis-Related Groups (DRG) ('falls and gait disorder', 'chronic obstructive pulmonary disease (COPD)', 'other major respiratory diseases and 'cellulitis'). Length of stay (LOS) in Emergency Department (ED) and in the hospital, mortality, readmissions within 1 month, and discharge destination. Eighty-nine patients were studied; 47 in the MAU group and 42 in the non-MAU group. The MAU cohort was significantly older (84.1 ± 7.9 years v. 80.4 ± 7.8 years, respectively, P=0.03); and had shorter ED LOS (4.9 ± 3.0h v. 6.5 ± 2.8h, P=0.012). Overall hospital LOS did not differ except for patients with 'cellulitis', (5.7 ± 4.9 days for MAU cohort v. 14.8 ± 6.8 days for non-MAU cohort, P=0.022). There was no significant difference in mortality, readmission rate or discharge destination. Conclusions. The MAU can be an effective service model for older patients. More research is required to confirm this and to define the key elements that are essential for its effectiveness.Australian health review: a publication of the Australian Hospital Association 08/2012; 36(3):331-5. · 0.55 Impact Factor -
Article: Serum C-reactive protein as a biomarker for early detection of bacterial infection in the older patient.
[show abstract] [hide abstract]
ABSTRACT: although C-reactive protein (CRP) is widely used in younger populations, its value for diagnosing bacterial infection in older population is not well established. This study examined the usefulness of serum CRP level in the early detection of bacterial infection in older patients. in a prospective cohort study, consecutive patients aged 70 years or over admitted to Aged Care wards were recruited. CRP levels were measured within 24 h of presentation, and their significance in predicting bacterial infections was analysed. The relationship between CRP and other clinical features of diagnosing bacterial infections (e.g. temperature, white cell count, neutrophil count, oxygen saturation, blood pressure and heart rate) was also examined. a total of 232 patients were recruited over a period of 3 months. CRP levels were 21.3 +/- 36.0 and 150.5 +/- 114.1 mg/l (mean +/- SD) in the non-infection and infection groups, respectively (P < 0.001). We found that the CRP cut-off value of 60 mg/l had the best combination of sensitivity and specificity. At this level, the sensitivity of diagnosing bacterial infection was 80.7%, specificity 96.0%, positive predictive value 91.9% and negative predictive value 89.8%. CRP and temperature had higher sensitivity and specificity than white cell count and neutrophil count in the diagnosis of infection. For every 1-mg/l increment in CRP, the risk of bacterial infection increases by 2.9%. CRP is a convenient and useful biomarker to predict early bacterial infection in older patients especially when other markers are atypical or not present.Age and Ageing 09/2010; 39(5):559-65. · 3.09 Impact Factor -
Article: Management and outcomes of delirious patients with hyperactive symptoms in a secured behavioral unit jointly used by geriatricians and pyschogeriatricians.
[show abstract] [hide abstract]
ABSTRACT: To compare the clinical outcomes and length of stay (LOS) between delirious patients with hyperactive symptoms admitted directly and those admitted indirectly from Emergency Department into a secured, behavioral unit jointly used by geriatricians and pyschogeriatricians (the Unit). A retrospective study analyzing data from the medical records of 122 patients with an admission diagnosis of delirium with hyperactive symptoms and subsequently discharged from the Unit, including restraint, one-to-one nursing care, falls, absconding, duration of delirium, recovery from delirium, destination and LOS. Significantly fewer patients with direct admission (n=68) required physical restraint or chemical restraint compared with those transferred (n=54). Patients admitted directly showed a higher discharge rate back home, shorter LOS, shorter duration of delirium and a higher rate of recovery from delirium than transferred patients. Of the transferred patients, more received one-to-one nursing care before transfer than after transfer. Three (5.6%) absconded before transfer, but none absconded from the Unit. The falls rate reduced from 14.2 to 6.7 falls/1000 patient delirium days after transfer. Delirious patients with hyperactive symptoms admitted directly to the Unit fared better in clinical outcomes and LOS. They also required less restraint, less intensive nursing and were unlikely to abscond compared to those transferred.Archives of gerontology and geriatrics 03/2010; 52(1):66-70. · 1.36 Impact Factor -
