How efficient is patient discharge following lower limb arthroplasty?

BACKGROUND: Appropriately timed patient discharge is essential for optimal patient care and efficient hospital functioning. The post-operative morbidity survey (POMS) is the only validated prospective method of measuring short-term post-operative morbidity. It has not previously been used as a bed utilisation tool. METHODS: We collected POMS data from 529 consecutive lower-limb arthroplasty patients over a 1-year period and recorded the number of patients remaining in the hospital without morbidity, together with alternative reasons for remaining in hospital. Data was collected on post-operative days (POD) 3, 5, 8 and 15. RESULTS: On POD 3, 45% of hip arthroplasty patients and 52% of knee arthroplasty patients remained in hospital with no identifiable morbidity. On POD 5, 53% of hip arthroplasty patients and 47% of knee arthroplasty patients remained in hospital with no identifiable morbidity. These figures declined by POD 8 and 15. The most common reason for inappropriate bed occupancy was ongoing physiotherapy and occupational therapy. CONCLUSIONS: We believe POMS is able to identify patients remaining in hospital with no significant morbidity and has utility as a prospective bed utilisation tool. Addition of a mobility measure to POMS may improve its utility in detecting morbidity requiring hospitalisation, particularly following lower limb arthroplasty.

Investigating risk factors for psychological morbidity three months after intensive care: a prospective cohort study.

INTRODUCTION: There is growing evidence of poor mental health and quality of life among survivors of intensive care. However, it is not yet clear to what extent the trauma of life-threatening illness, associated drugs and treatments, or patients' psychological reactions during intensive care contribute to poor psychosocial outcomes. Our aim was to investigate the relative contributions of a broader set of risk factors and outcomes than had previously been considered in a single study. METHODS: A prospective cohort study of 157 mixed-diagnosis highest acuity patients was conducted in a large general intensive care unit (ICU). Data on four groups of risk factors (clinical, acute psychological, socio-demographic and chronic health) were collected during ICU admissions. Post-traumatic stress disorder (PTSD), depression, anxiety and quality of life were assessed using validated questionnaires at three months (n = 100). Multivariable analysis was used. RESULTS: At follow-up, 55% of patients had psychological morbidity: 27.1% (95% CI: 18.3%, 35.9%) had probable PTSD; 46.3% (95% CI: 36.5%, 56.1%) probable depression, and 44.4% (95% CI: 34.6%, 54.2%) anxiety. The strongest clinical risk factor for PTSD was longer duration of sedation (regression coefficient = 0.69 points (95% CI: 0.12, 1.27) per day, scale = 0 to 51). There was a strong association between depression at three months and receiving benzodiazepines in the ICU (mean difference between groups = 6.73 points (95% CI: 1.42, 12.06), scale = 0 to 60). Use of inotropes or vasopressors was correlated with anxiety, and corticosteroids with better physical quality of life. CONCLUSIONS: Strikingly high rates of psychological morbidity were found in this cohort of intensive care survivors. The study's key finding was that acute psychological reactions in the ICU were the strongest modifiable risk factors for developing mental illness in the future. The observation that use of different ICU drugs correlated with different psychological outcomes merits further investigation. These findings suggest that psychological interventions, along with pharmacological modifications, could help reduce poor outcomes, including PTSD, after intensive care.

A multidisciplinary team approach to weaning from prolonged mechanical ventilation.

OBJECTIVE: To establish whether multidisciplinary team-led strategies to maintain continuity across the weaning process result in an increase in the proportion of patients surviving prolonged mechanical ventilation and reduce the length of time patients are ventilated. DESIGN: A quality improvement programme was conceived and implemented for patients receiving mechanical ventilation for >21 days. SETTING: University teaching hospital general intensive care unit. INTERVENTIONS: The introduction of long-term weaning plans. MEASUREMENTS AND MAIN RESULTS: Intensive care unit survival odds ratio and 95% confidence interval. 0.181 (0.06-0.49) P<0.01 and hospital survival odds ratio and 95% confidence interval 0.2 (0.08-0.61) P<0.01, Duration of mechanical ventilation (median 95@ confidence interval ) 53 days (32-37) vs 43 days (39-44) P=0.03. CONCLUSION: Long-term weaning plans led by a multidisciplinary, team were associated with a reduction in intensive care unit and hospital mortality, and duration of mechanical ventilation in patients ventilated for ≥ 21 days. Strategies to maintain continuity in this patient parent group are likely fundamental to improving outcome.
