The impact of psychological factors in recovery following surgery for hip fracture.

PURPOSE: To increase awareness of psychological factors in recovery from hip fracture and to describe strategies that can be used to help patients in the process of recovery. METHOD AND RESULTS: Psychological theory, case examples and clinical observation are used to propose three frameworks for understanding the psychological factors which can impede recovery. Indication of key strategies for assessment and intervention which can be used in rehabilitation services is provided. CONCLUSIONS: An understanding of the psychological factors which can impede recovery in hip fracture is important for all professionals involved in rehabilitation. Psychologists can provide consultation and support for staff working in physical rehabilitation and can work directly with cases where there is complexity. There is still relatively little known about this important area and further research is needed to provide a clear evidence base.

Predictors of incident depression after hip fracture surgery.

OBJECTIVE: Depression after hip fracture surgery is prevalent and associated with increased mortality rates and impaired functional recovery. The incidence of new-onset depressive symptoms in patients initially not depressed after hip fracture surgery and their relationship with functional recovery is unknown. METHODS: A cohort of 139 nondepressed elderly patients (>60 years) hospitalized for hip fracture surgery were followed up for six months. Clinically significant depressive symptoms were defined as a score of 7 or more on the 15-item Geriatric Depression Scale. RESULTS: The authors found a cumulative incidence rate of 20.5% adjusted for dropouts. Multiple Cox-regression analyses yielded the presence of subthreshold symptoms of depression, anxiety, pain, and cognitive impairment at baseline, the premorbid level of mobility, and a history of (treated) depression as risk factors for incident depression (p <0.05). A forward, conditional procedure identified postoperative pain (hazard ratio [HR] = 1.32, 95% confidence interval [CI]: 1.14-1.53, Wald chi(2) = 13.57, df = 1, p <0.001) and baseline anxiety (HR = 1.25, 95% CI: 1.08-1.44, Wald chi(2) = 8.86, df = 1, p = 0.003) as the strongest independent risk factors. Incident depression was associated with a less favorable outcome at 3 months follow-up. CONCLUSION: This exploratory study identified two treatable baseline characteristics that predicted incident depression in nondepressed patients after hip-fracture surgery.

Treatment and prevention of depression after surgery for hip fracture in older people: randomized, controlled trials.

OBJECTIVES: To evaluate the effect of a psychiatric intervention in treating depression (treatment study) and the effect of a psychological treatment in preventing depression (prevention study) after hip fracture in older people. DESIGN: Two linked randomized, controlled trials. SETTING: Orthopedic units in Manchester, England. PARTICIPANTS: Two hundred ninety-three older people who had undergone surgery for a fractured hip: 121 in the treatment study and 172 in the prevention study. MEASUREMENTS: The Geriatric Depression Scale and Hospital Anxiety and Depression Scale for mood, functional tests for mobility and pain measures. RESULTS: There was a slight reduction in depressive symptoms in the active arm of the treatment study. In the prevention study, there was no significant difference in incident depression between the psychological intervention and treatment as usual. There were no differences in the functional and pain outcomes. CONCLUSION: The results from these two randomized, controlled trials show that, after hip fracture surgery, no statistically significant benefits can be achieved from a psychiatric intervention in people who are depressed or a psychological intervention to prevent the onset of depression.

Fear of falling more important than pain and depression for functional recovery after surgery for hip fracture in older people.

BACKGROUND: Depression and cognitive functioning have a negative impact on functional recovery after hip fracture surgery in older people, and the same has been suggested for pain and fear of falling. These variables, however, have never been studied together, nor has the timing of psychiatric assessment been taken into account. METHOD: Two parallel, randomized controlled trials were undertaken aiming to prevent and treat depression after hip fracture surgery in older people. Multiple logistic regression analyses corrected for age and pre-morbid level of functioning were performed to evaluate the effect of depressive symptoms (15-item Geriatric Depression Scale, GDS), pain (Wong-Baker pain scale), cognitive functioning (Mini-mental State Examination, MMSE) and fear of falling (Modified Falls Efficacy Scale, MFES) within 2 weeks after surgery and 6 weeks later on functional recovery at 6 months. Main outcome measures were performance-based measures (up-and-go test, gait test, functional reach) and the self-report Sickness Impact Profile (SIP) questionnaire to assess the impact of the hip fracture on activities of daily living (ADL). RESULTS: Two hundred and ninety-one patients participated and outcome measures for 187 (64%) patients were available at 6 months. All mental health variables interfered with functional recovery. However, in the final multivariate model, cognitive functioning and fear of falling assessed 6 weeks after surgery consistently predicted functional recovery, whereas pain and depressive symptoms were no longer significant. CONCLUSION: Fear of falling and cognitive functioning may be more important than pain and depression to predict functional recovery after hip fracture surgery. Rehabilitation strategies should take this into account.

When a little knowledge is a dangerous thing...: a study of carers' knowledge about dementia, preferred coping style and psychological distress.

OBJECTIVES: The aim of this study was to improve understanding of the relationship between carers' existing knowledge about dementia, their coping style and psychological morbidity. METHOD: Fifty carers and patients attending day services were recruited. Carers were given questionnaires to assess knowledge of dementia, preferred coping style, anxiety, depression and strain. RESULTS: The results indicated that carers who demonstrated more knowledge about the biomedical aspects of dementia were more anxious (p < 0.05). Furthermore, carers who had a preferred coping style of monitoring for threat relevant information were more anxious (p < 0.005). CONCLUSIONS: Understanding more about those factors that are associated with knowledge about dementia will help to identify profiles of carers who are in need of education and in matching individually tailored interventions to carers with specific learning needs.

Economic impact of a specialist outreach team in residential and nursing home settings.

BACKGROUND: The results of a randomized controlled trial have indicated that a training and educational programme for staff in nursing or residential homes may result in reductions in levels of depression and levels of cognitive impairment for residents presenting with an active management problem. The training and educational intervention consisted of members of a hospital outreach team who presented a series of 1 hour seminars on topics which staff had indicated would improve their knowledge and skills. AIMS OF THE STUDY: The aim of this study was to present an exploratory analysis of the impact on costs associated with providing an old age psychiatry outreach team giving training and education for staff in nursing and residential homes. METHOD: For the economic study, a societal perspective was employed. Measures of resource use and costs to the health service, social and community services and the nursing and residential homes were analysed for 120 residents from 12 nursing or residential homes, as part of a randomized controlled trial to assess a training package provided in residential and nursing homes. Cost estimates were based on estimates from generalized estimated equations. To allow for clustering effects within homes, the unit of randomization was the home as opposed to the individual. To ensure models were correctly specified, several tests including the Ramsey RESET test were employed. RESULTS: There were no significant differences in the total cost per person in the homes that received the intervention and the control homes. This study has shown that the additional cost of providing the specialist outreach team was likely to be covered by reductions in the use of other resources such as GP visits to nursing and residential homes. Therefore, though the study had limitations, it appeared that improved care could be provided at little or no extra cost. IMPLICATIONS FOR HEALTH CARE PROVISION AND USE: The evidence presented suggests that the specialist outreach team was unlikely to add to the total cost of caring for residents in nursing and residential homes. This finding combined with the benefits in terms of lower levels of depression and cognitive impairment suggested that the intervention was good value for money. The intervention should be considered for use in other nursing and residential homes.
