Short-term morbidity factors associated with length of hospital stay (LOS): Development and validation of a Hip Fracture specific postoperative morbidity survey (HF-POMS).

BACKGROUND: We aimed to describe and quantify postoperative complications in the older hip fracture population, develop and validate a hip fracture postoperative morbidity survey tool (HF-POMS). METHODS: A prospective clinical observation study of patients (≥ 70 years) admitted for emergency hip fracture surgery, was conducted across three English National Health Service hospitals. Outcome data items were developed from the Postoperative Morbidity Survey (POMS), Cardiac-POMS, hip fracture postoperative literature and orthogeriatric clinical team input. Postoperative outcome data were collected on days 1, 3, 5, 8 and 15; 341 patients participated. RESULTS: A 12-domain HF-POMS tool was developed with acceptable construct validity on all HF-POMS days. Patients with high perioperative risk scores as measured by the NHFS and ASA grade were more prone to develop HF-POMS defined morbidities. High morbidity rates occurred in the following domains; renal, ambulation assistance, pain and infectious. Presence of any morbidity on postoperative days 8 and 15 was associated with subsequent length of stay of 3.08 days (95% CI 0.90-5.26, p = 0.005) and 15.81 days (95% CI 13.35-18.27, p = 0.001) respectively. Observed average length of stay was 16.9 days. HF-POMS is a reliable and valid tool for measuring early postoperative complications in hip fracture patients. Additional domains are necessary to account for all morbidity aspects in this patient population compared to the original POMS. CONCLUSION: Many patients remained in hospital for non-medical reasons. HF-POMS may be a useful tool to assist in discharge planning and randomised control trial outcome definitions.

The determinants of successful in-hospital rehabilitation in people aged 90 years and older.

BACKGROUND/OBJECTIVES: The very elderly constitute a subgroup of elderly who may respond differently than the younger elderly to medical intervention. This possibility has not previously been investigated. Our study investigates whether successful rehabilitation of the very elderly is possible within the current processes of care and also whether factors that help predict successful rehabilitation in all age elderly are applicable to the oldest old. METHODS: A retrospective case note analysis of all very elderly people (>or=90 years old) treated within in-patient elderly person rehabilitation facilities at the Northern General Hospital, Sheffield. Potential predictive factors analysed: Barthel index, main presenting illness, number of co-morbid conditions, number of regular prescribed medications, abbreviated mental test score, prior formal social services input, previous hospital admission within 1 year and serum albumin (g/l). Outcome measures reflecting success of rehabilitation: duration of rehabilitation (days), discharge destination to the same ('good outcome') or increased ('poor outcome') level of social and/or nursing care, readmission to hospital within 30 days of discharge and death during rehabilitation or within 120 days of discharge. RESULTS: Of 230 nonagenarians admitted to inpatient elderly rehabilitation 47% required no increase in social support following their admission and 76% of those admitted from their own home were able to return there. Barthel index and the number of co-morbid conditions were the most influential predictors of success, with Barthel index predicting length of stay (p < 0.001), discharge destination (p < 0.001) and in-hospital mortality (p < 0.01) and co-morbidity predicting readmission to hospital (p = 0.05), in-hospital mortality (p = 0.04) and survival (p = 0.05). On multi-variate analysis all other predictive factors analysed, except for presenting illness, were associated with at least one outcome measure (p < 0.05). CONCLUSION: Successful inpatient rehabilitation of the very elderly is possible. Factors that predict the success of rehabilitation of nonagenarians are similar to those associated with success in the younger elderly. The factors that most broadly predict success are Barthel index and the number of co-morbid conditions identified at admission to rehabilitation. Main presenting illness did not emerge as a predictor within this group.

Small bowel bacterial overgrowth. An underrecognized cause of malnutrition in older adults.

Small bowel bacterial overgrowth (SBBO) is an important and under-recognized clinical syndrome in the elderly. It is the most common cause of malabsorption among older adults. Presentation of SBBO syndrome is often occult, which makes it imperative to maintain a high index of suspicion for this disorder. When symptomatic bacterial overgrowth is appropriately identified and treated there can be positive dramatic results. This article discusses the importance of considering a diagnosis of bacterial overgrowth in those predisposed to its development and the mechanisms by which nutrient malabsorption occurs. Signs and symptoms of bacterial overgrowth, differential diagnosis, investigation, and current treatment options are discussed.
