- 1996

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Foot problems are not only the most common but in general also the most severe of the diabetic complications. The age group 15-50 yrs in this study was chosen because these patients were considered to be at their most active age and were felt to require optimal foot function.380 patients (96 %) participated, 78 % with Type 1, 20 % Type 2 and 1 % with secondary diabetes mellitus (DM) and 100 healthy controls. Only six patients had signs of peripheral ischaemia but half of the patients had deformities such as fallen forefoot arches and hammer toes. With sensory thresholds and clinical signs it was demonstrated that age, duration of DM and tall stature are major risk factors for diabetic neuropathy. Gender differences depend on differences in height. Dorsiflexion of the toes against resistance was used to test the function and volume of m.extensor digitorum brevis. When compared with measurements of sensory thresholds for vibration, perception and pain, it was found to be a valuable test for screening of distal motor neuropathy.To prevent worsening of foot deformities 266 patients with Type 1 DM were followed for 3 years. Those with the most pronounced deformities were fitted with custom-made insoles and had repeated examinations. Improvement was more common in patients with insoles compared to patients without insoles.Bone mineral density (BMD) was measured in nine patients with osteopathy in their feet and 18 controls. BMD was lower in L2-L3, but not in the proximal femur, implying osteopenia being a possible risk factor for distal osteopathy.Plaster cast treatment was used in 33 diabetic patients with severe foot ulcers who were selected because previous conservative treatment had been unsuccessful and they had been judged unsuitable for vascular surgery. The lesions healed in 19 patients.In conclusion, the main findings demonstrate the need for an increased awareness of early preventive foot care in young and middle-aged diabetic patients.

- BACKGROUND AND AIMS: Delirium is a common postoperative complication in elderly patients which has a serious impact on outcome in terms of morbidity and costs. We examined whether a postoperative multi-factorial intervention program can reduce delirium and improve outcome in patients with femoral neck fractures.METHODS: One hundred and ninety-nine patients, aged 70 years and over (mean age+/-SD, 82+/-6, 74% women), were randomly assigned to postoperative care in a specialized geriatric ward or a conventional orthopedic ward. The intervention consisted of staff education focusing on the assessment, prevention and treatment of delirium and associated complications. The staff worked as a team, applying comprehensive geriatric assessment, management and rehabilitation. Patients were assessed using the Mini Mental State Examination and the Organic Brain Syndrome Scale, and delirium was diagnosed according to DSM-IV criteria.RESULTS: The number of days of postoperative delirium among intervention patients was fewer (5.0+/-7.1 days vs 10.2+/-13.3 days, p=0.009) compared with controls. A lower proportion of intervention patients were delirious postoperatively than controls (56/102, 54.9% vs 73/97, 75.3%, p=0.003). Eighteen percent in the intervention ward and 52% of controls were delirious after the seventh postoperative day (p<0.001). Intervention patients suffered from fewer complications, such as decubitus ulcers, urinary tract infections, nutritional complications, sleeping problems and falls, than controls. Total postoperative hospitalization was shorter in the intervention ward (28.0+/-17.9 days vs 38.0+/-40.6 days, p=0.028).CONCLUSIONS: Patients with postoperative delirium can be successfully treated, resulting in fewer days of delirium, fewer other complications, and shorter length of hospitalization.

Old people with femoral neck fracture : delirium, malnutrition and surgical methods - an intervention program

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Hip fracture is a global and a growing public health problem. More women than men sustain hip fractures, the incidence increases exponentially with age and mean age is above 80. About one third of hip-fracture patients suffer from dementia and are prone to develop acute confusional state (delirium). Delirium is one of the most common complications after hip-fracture surgery, and seriously impacts on morbidity and mortality. Malnutrition is also common in hip-fracture patients and is associated with postoperative complications, such as delayed healing of the wound, infections and decubitus ulcers. Arthroplasty is usually preferred procedure in displaced femoral neck fractures but is, however, controversial in patients with dementia due to the fear of dislocation of the prosthesis. The aims of this thesis are to identify risk factors for delirium and the impact of delirium on rehabilitation outcome, to evaluate whether a postoperative multi-factorial intervention program could reduce delirium, to investigate the effect of a nutritional intervention and to evaluate complications, functional outcome and mortality regarding two surgical methods, hemiarthroplasty (HAP) and internal fixation (IF), in old patients with femoral neck fracture. Thirty-eight out of 61 consecutive patients (62%) were delirious on admission to hospital or developed postoperative delirium. An increased risk of postoperative delirium was found among hip-fracture patients with dementia and/or depression. Delirious patients were hospitalized longer, were more dependent in their activities of daily living, had poorer psychological well-being and suffered more complications than non-delirious patients. A postoperative multi-factorial and multidisciplinary intervention program reduced the incidence, at 55% vs 75% (p=0.003), and number of days with delirium, 5 vs 10 days (p=0.009). Postoperative complications were also reduced; decubitus ulcers 9% vs 22% (p= 0.010), urinary tract infections 31% vs 51% (p=0.005), falls 12% vs 27% (p=0.007), and the mean hospitalization period was 10 days shorter in the intervention group (p=0.030). Malnutrition was common among all these patients (53 %) and associated with postoperative complications such as decubitus ulcers and delirium. However, the nutritional intervention had no effect on nutritional parameters at four months, nevertheless men had better nutritional outcomes than women. A higher proportion of patients with dementia operated on using HAP had regained their pre-fracture ability to walk independently at the one-year follow up compared with those operated on using IF. Six of 83 patients dislocated their HAP during hospitalization and during an episode of delirium, none had dementia. No difference in mortality between the surgical methods was seen. Dementia per se should not be a reason to disqualify patients from being treated with the most appropriate surgical method. It is clinically important to discriminate between dementia and delirium, since delirium can be prevented and treated even in patients with dementia. Old patients undergoing surgery have special needs that are not always catered for in ordinary orthopaedic or surgical wards. The special care for these patients should include: a combined nursing and medical care based on comprehensive geriatric assessments, systematic prevention, detection and treatment of postoperative complications such as delirium, hypoxemia, urinary tract infections, pain, malnutrition and an active rehabilitation. It is obvious that improved quality of care reduces patient suffering and seemingly the costs for society.

- Fractures are a serious complication after stroke. Among patients with femoral neck fractures, a large subgroup have had a previous stroke. This study aimed to investigate the incidence of fractures after stroke. Included in the study were 1139 patients consecutively admitted for acute stroke. Fractures occurring from stroke onset until the end of the study or death were registered retrospectively. Hip fracture incidence was compared with corresponding rates from the general population. Patients were followed up for a total of 4132 patient-years (median 2.9 years). There were 154 fractures in 120 patients and median time between the onset of stroke and the first fracture was 24 months. Women had significantly more fractures than men (chi 2 = 15.6; p < 0.001). In patients with paresis most of the fractures affected the paretic side (chi 2 = 22.5; p < 0.001) and 84% of the fractures were caused by falls. Hip fracture was the most frequent fracture and the incidence was 2-4 times higher in stroke patients compared with the reference population. Fractures are thus a common complication after stroke. They are usually caused by falls and affect the paretic side. It is necessary to focus on the prevention of post-stroke fractures, including the prevention of both falls and osteoporosis.

- INTRODUCTION: This study evaluates whether a postoperative multidisciplinary, intervention program, including systematic assessment and treatment of fall risk factors, active prevention, detection, and treatment of postoperative complications, could reduce inpatient falls and fall-related injuries after a femoral neck fracture.METHODS: A randomized, controlled trial at the orthopedic and geriatric departments at Umeå University Hospital, Sweden, included 199 patients with femoral neck fracture, aged >or=70 years.RESULTS: Twelve patients fell 18 times in the intervention group compared with 26 patients suffering 60 falls in the control group. Only one patient with dementia fell in the intervention group compared with 11 in the control group. The crude postoperative fall incidence rate was 6.29/1,000 days in the intervention group vs 16.28/1,000 days in the control group. The incidence rate ratio was 0.38 [95% confidence interval (CI): 0.20 - 0.76, p=0.006] for the total sample and 0.07 (95% CI: 0.01-0.57, p=0.013) among patients with dementia. There were no new fractures in the intervention group but four in the control group.CONCLUSION: A team applying comprehensive geriatric assessment and rehabilitation, including prevention, detection, and treatment of fall risk factors, can successfully prevent inpatient falls and injuries, even in patients with dementia.
