Predictors of functional outcomes after surgical treatment of distal radius fractures.

PURPOSE: Identifying predictors of outcomes is important in anticipating and treating patients with underlying factors that may affect recovery. The predictors of functional outcomes after distal radius fracture (DRF) treatment have not been well defined in the past. METHODS: This was a prospective cohort study designed to identify predictors of hand outcomes after DRF treatment. The study included consecutive patients with inadequately reduced DRFs who had open reduction and internal fixation with volar plating. Demographic and socioeconomic data were collected at the time of the initial treatment. Outcome data were collected 3, 6, and 12 months after surgery. Outcome evaluation consisted of radiographic measurements and the Michigan Hand Outcomes Questionnaire (MHQ). We hypothesized that the following factors are important predictors of functional outcomes: (1) age, (2) socioeconomic status, (3) severity of fracture pattern, and (4) postsurgical radiographic measurements. Regression models were developed using the overall MHQ score as the outcome variable at 3 months and 1 year after surgery. RESULTS: Sixty-six patients had data available at 3 months and 49 patients had data available at 1 year. At 3 months after surgery, radiographic incongruity (step + gap) was a significant predictor after controlling for age, fracture type, dorsal-volar tilt angulation, and income. Patients with increased incongruity reported lower MHQ scores (worse functional outcomes). At 1 year after surgery, however, only age and income were significant predictors after controlling for fracture type. Increased age and decreased income were associated with lower MHQ scores. CONCLUSIONS: After successful surgery and hand therapy, only age and income were significantly associated with long-term outcomes 1 year after surgery. Precise anatomic reduction enhances short-term functional outcomes in DRF treatment. TYPE OF STUDY/LEVEL OF EVIDENCE: Prognostic, Level I.

Functional outcome after brain tumor and acute stroke: a comparative analysis.

OBJECTIVE: To compare the functional outcome, length of stay, and discharge disposition of patients with brain tumors and those with acute stroke. DESIGN: Case-controlled, retrospective study at a tertiary care medical center inpatient rehabilitation unit. SUBJECTS: Sixty-three brain tumor patients matched with 63 acute stroke patients according to age, sex, and location of lesion. MAIN OUTCOME MEASURES: The functional independence measure (FIM) was measured on admission and discharge. The FIM change and FIM efficiency were also calculated. The FIM was analyzed in three subsets: activities of daily living (ADL), mobility (MOB), and cognition (COG). Discharge disposition and rehabilitation length of stay were compared. RESULTS: Demographic variables of race, marital status, and payer source were comparable for the two groups. No significant difference was found between the brain tumor and stroke populations with respect to total admission FIM, total discharge FIM, change in total FIM, or FIM efficiency. The admission MOB-FIM was found to be higher in the brain tumor group (13.6 vs 11.1, p = .04), whereas the stroke group had a greater change in ADL-FIM score (10.8 vs 8.3, p = .03). The two groups had similar rates of discharge to community at greater than 85%. The tumor group had a significantly shorter rehabilitation length of stay than the stroke group (25 vs 34 days, p < .01). CONCLUSION: Brain tumor patients can achieve comparable functional outcome and rates of discharge to community and have a shorter rehabilitation length of stay than stroke patients.

Functional outcome in correction of perineal fistula in boys with anoplasty versus posterior sagittal anorectoplasty.

Optimal surgical therapy for low anorectal anomalies remains controversial. We compared functional outcome after correction of perineal fistula in boys with either anoplasty (AP) or limited posterior sagittal anorectoplasty (PSARP). Thirty-nine boys from two centres treated for perineal fistula with either AP (n = 24) or PSARP (n = 15) from 1996 to 2001 underwent prospective follow-up for functional outcome. In order to minimize heterogeneity of the study groups, only boys with perineal fistula were included. Functional outcome was assessed using a validated bowel function score (maximum score 20). Day and night time wetting as well as the age at potty training were also recorded. An independent nurse specialist interviewed caregivers. AP and PSARP groups were comparable regarding age, associated malformations and frequency of sacral dysplasia. No significant differences between the groups were observed in the overall median bowel function score, AP 18 (11-20) versus PSARP 18 (11-20), or in the age at potty training, AP 32 (14-66) versus PSARP 36 (18-60). Covering colostomy was employed significantly (P < 0.05) more often with PSARP (10/15) than with AP (1/24). Surgery for local complications was carried out significantly (P < 0.05) more often after PSARP (5/15) than after AP (2/24). Two patients in both groups required a temporary salvage colostomy. Overall functional outcome is comparable after AP and PSARP for perineal fistula in boys. As a more straightforward procedure AP is safer and less prone to complications avoiding the need for covering colostomy.

Functional outcome assessment of aphasia following left hemisphere stroke.

This article discusses issues regarding the assessment of functional outcomes in individuals who have aphasia following stroke. Some different approaches to functional outcome measurement are critically reviewed, ranging from general measures of stroke outcome to measures that have been designed specifically for aphasic individuals, to measurements focusing on aphasia's effects on quality of life. Examples of how to relate treatment of aphasia directly to functional outcomes assessment are also provided.

Functional outcomes and quality of life in patients with brain tumors: a preliminary report.

OBJECTIVES: To determine the relationship between functional outcome and quality of life (QOL) in patients with brain tumors receiving inpatient rehabilitation, and to assess the sensitivity of 4 assessment tools in measuring changes in that population. DESIGN: Prospective study using longitudinal data collected from consecutively admitted patients. SETTING: Acute inpatient rehabilitation unit. PARTICIPANTS: Ten patients with primary brain tumors admitted to an acute inpatient rehabilitation unit. INTERVENTIONS: Patients participated in an inpatient interdisciplinary rehabilitation program that used the following disciplines: occupational therapy, rehabilitation therapy, recreational therapy, speech therapy, physical therapy, rehabilitation nursing and case management. MAIN OUTCOME MEASURES: The FIM instrument, Disability Rating Scale (DRS), Karnofsky Performance Status Scale (KPS), Functional Assessment of Cancer Therapy-Brain (FACT-BR). RESULTS: Improvement in total functional outcome was indicated by all 3 functional measures (FIM: F = 46.84, p < .05; DRS: F = 19.25, p < .05; KPS: F = 10.11, p < .05). Significant improvements were found between admission and discharge scores for the FIM and DRS. The KPS revealed significant improvement between admission and 3-month follow-up scores. All admission and discharge functional scales (FIM, DRS, KPS) correlated significantly with each other. No significant change was noted in the FACT-BR between admission and discharge scores, but FACT-BR scores did improve at 1- and 3-months postdischarge relative to admission. The FIM, KPS, and DRS did not show significant correlation with the FACT-BR. Ninety percent of patients were initially discharged to a home environment. CONCLUSION: Although patients make functional gains during and after inpatient rehabilitation, gains in QOL are not significant until 1 month postdischarge. QOL does not appear to correlate well with functional outcomes. Further, the KPS is less sensitive than the FIM and DRS in detecting change in functional status.

Functional outcomes of kyphoplasty for the treatment of osteoporotic and osteolytic vertebral compression fractures.

INTRODUCTION: Vertebral body compression fractures secondary to osteoporosis or malignant osteolysis are an increasingly common problem. The primary purpose of our study was to assess functional outcomes of kyphoplasty for the treatment of osteoporotic and osteolytic vertebral compression fractures. Our secondary purpose was to compare such functional outcomes in patients with osteoporosis versus multiple myeloma. METHODS: The 314 consecutive patients prospectively included in our study had progressive and painful compression fractures as a result of osteoporosis or multiple myeloma that were refractory to nonoperative modalities. Of those 314 patients, the 211 (67.2%) patients (155 with osteoporosis and 56 with multiple myeloma) who had complete preoperative and postoperative data formed our final study group. All patients tolerated the kyphoplasty procedure well (that is, there were no adverse events in terms of perioperative patient condition). Follow-up ranged from 1 to 235 weeks (mean 55.0 weeks). Functional outcomes were assessed by the SF-36 and Oswestry Disability Index at baseline and at follow-up examinations. Data were analyzed by Student's t-test and the level of significance was set at P<or=0.05. RESULTS: The average Owestry Disability Index score decreased by 12.6 points (P<0.001) in the overall group, by 11.8 points (P<0.001) at short-term follow-up, and by 8.6 points (P<0.001) at long-term follow-up. All SF-36 sub-scores except for general health and role-emotional showed statistically significant improvement from baseline values at the same time points. There was no statistically significant difference with regard to functional outcome in the osteoporosis and multiple myeloma sub-groups. CONCLUSIONS: Kyphoplasty provided a safe and effective treatment for pain and disability in patients with verterbral compression fractures secondary to osteoporosis and multiple myeloma. In addition, we found no statistically significant difference with regard to functional outcome between patients with osteoporosis and multiple myeloma.

Functional outcomes and daily life activities of African-American elders after hospitalization.

OBJECTIVE: African-American elders were recruited from a transitional unit after hospitalization and tracked for 6 months in the community after discharge to (a) examine functional outcomes on the unit and in the community and (b) identify patterns of participation in daily life activities. The International Classification of Impairments, Disabilities, and Handicaps (ICIDH-2) framework provided the structure to examine the connections among body systems, functional outcomes, and social participation for this population that has been underrepresented in past research. METHOD: A mixed design combined qualitative and quantitative methods, including qualitative interviews to document personal adaptive experience, a standardized functional assessment to identify functional outcomes, and a structured format to record activity participation. RESULTS: Findings revealed that 11 of the 17 participants improved their functional outcomes after discharge. Three patterns of activity participation identified were self-care, self-care and household management, and mixed activities. Contextual influences were diverse family support arrangements. CONCLUSION: Complex relationships were identified among body systems, functional outcomes, and daily life activities that were influenced by individual values and support arrangements.

Posttraumatic amnesia: its relation to functional outcome.

OBJECTIVE: To investigate the relation between duration of posttraumatic amnesia (PTA) and functional outcome in a traumatically brain injured population. PATIENTS: Two hundred seventy-six patients with traumatic brain injury (TBI) who were admitted to a Level I university trauma center and required inpatient rehabilitation. MEASURES: Duration of PTA was assessed by serial administrations of the Galveston Orientation Amnesia Test (GOAT). Functional Independence Measure (FIM) total scores, FIM cognitive and motor subscores, and Disability Rating Scale (DRS) scores were obtained at admission and discharge from inpatient rehabilitation. RESULTS: Duration of PTA was a significant predictor of all admission and discharge DRS and FIM scores. Duration of PTA and age at the time of injury, in combination, contributed significantly to the prediction of the DRS score and FIM total, cognitive, and motor scores at discharge. CONCLUSION: Duration of PTA appears to be a useful variable in predicting specific functional outcome in the TBI population receiving inpatient rehabilitation services. The use of age as a factor in addition to duration of PTA enhances the prediction of functional outcome.

Medication adherence and long-term functional outcomes in the treatment of schizophrenia in usual care.

BACKGROUND: Relatively little is known about the relationships between medication adherence and long-term functional outcomes in the treatment of schizophrenia. To extend previous research, we prospectively examined the relationships between adherence with any antipsychotic medication and functional outcomes among schizophrenia patients treated over a 3-year period, assessed the stability of adherence over time, and examined whether adherence in the first year predicts changes in functional outcomes over the following 2 years. METHOD: Analyses included 1906 participants with DSM-IV diagnoses of schizophrenia or schizoaffective or schizophreniform disorder in a multi-site, 3-year, prospective, naturalistic study conducted in the United States between July 1997 and September 2003. Outcome measures were assessed at 6-month intervals using systematic medical record abstraction and structured interview of patients. Adherence with antipsychotic regimen was assessed using patient-reported adherence and the medication possession ratio (percent days with prescription for any antipsychotic), dichotomized into adherence and non-adherence. Analyses employed generalized estimating equations and mixed models with repeated measures. RESULTS: Nonadherence was associated with poorer functional outcomes, including greater risks of psychiatric hospitalizations, use of emergency psychiatric services, arrests, violence, victimizations, poorer mental functioning, poorer life satisfaction, greater substance use, and more alcohol-related problems (all p < .001). Adherence was relatively stable, with 77.3% of patients maintaining the same adherence status from the first year to the second year. Nonadherence in the first year predicted significantly poorer outcomes in the following 2 years. CONCLUSIONS: Findings highlight the importance of adherence with antipsychotic medication in the long-term treatment of schizophrenia and its potential beneficial impact on the mental health and criminal justice delivery systems.

Brief postoperative delirium in hip fracture patients affects functional outcome at three months.

UNLABELLED: It is unclear how brief postoperative delirium (DEL) affects functional outcomes. In this study, we sought to determine if patients with brief postoperative DEL (<6-wk duration) have different living situations when compared with non-DEL patients after hip fracture repair. In a prospective study, patients admitted to the geriatric hip fracture service were assessed every postoperative day for the presence of DEL using the confusion assessment method (CAM) score. Patients were reassessed at 6 wk and 3 mo postoperatively for CAM score, current living situation, and activities of daily living. Group comparisons were tested after dividing patients into two groups: DEL (DEL; [+] CAM at any time during the postoperative period while in the hospital); no-DEL (no DEL; [-] CAM throughout the postoperative period while in the hospital). The study included 92 patients of whom 26 (28%) were CAM (+) after surgery. At 6 wk follow-up, n = 81; at 3 mo follow-up, n = 76. Eight patients died during the study. At 6 wk and 3 mo, a larger percentage of DEL patients were not living with a family member (27% versus 8% patients not living with a family member at 3 mo follow-up in DEL and no-DEL, respectively). There was no difference in activities of daily living by 3 mo. We conclude that brief postoperative DEL lasting <6 wk is a determining factor for poor long-term functional outcome after hip fracture repair, because it significantly impacts the ability to live independently. IMPLICATIONS: Brief postoperative delirium lasting <6 wk is a determining factor for poor long-term functional outcome after hip fracture repair, because it significantly impacts the ability to live independently.

Tubularized incised plate repair: functional outcome after intermediate followup.

PURPOSE: We describe the functional outcome following tubularized incised plate repair of hypospadias in toilet trained children after an intermediate followup. MATERIALS AND METHODS: Children were included in this study only if they were toilet trained and had flow rate data not less than 6 months after primary tubularized incised plate hypospadias repair or 2 months after any secondary procedure to correct complications. Uroflow data (peak flow, voided volume and post-void residuals) were analyzed and plotted on previously determined age-volume dependent nomograms. RESULTS: Of the 48 boys 39 required no secondary procedures, while 9 secondary fistula closures were performed in 2, meatotomy in 2 and dilation in 5. After either primary (26) or secondary (7) procedures 33 of the 48 patients (68.7%) had normal peak flow rate and 15 (31.3%) had low peak flow rate. Of the 48 patients 46 had post-void residual urine less than 10% of voided volume. CONCLUSIONS: Most children will void efficiently with no straining and no post-void residual (1/2) to 4 years after tubularized incised plate hypospadias repair. Of our patients 68.7% have normal peak flow rate. Intermediate followup of larger series and followup at puberty are recommended to resolve the debate concerning the long-term functional outcome of tubularized incised plate hypospadias repair.

Functional outcome after posterolateral spinal fusion using pedicle screws: comparison between primary and salvage procedure.

Lumbar spinal fusion is a commonly performed surgical procedure, yet both the indications for its performance and its results remain controversial. It is generally believed that apart from situations where obvious measurable instability exists, a repeat surgical procedure such as spinal fusion does not improve the functional outcome in more than an average of 50% of cases. The aim of this study was to analyse functional outcome after posterolateral lumbar or lumbosacral spinal fusion, comparing primary and salvage procedures. It was designed as a prospective case/referent study with a 2-year follow-up. A total of 39 patients underwent a short posterior fusion with Cotrel-Dubousset (CD) pedicle screw fixation after earlier surgery of the lumbar spine. Two patients were erroneously omitted from the study at the index, so 37 patients were included in the salvage group. In the same period, 69 patients underwent lumbar fusion with pedicle screw fixation (CD) as primary surgery (referent group). Functional outcome was assessed by means of the Dallas Pain Questionnaire preoperatively and 1 and 2 years postoperatively. Fusion rates were determined by ordinary X-ray evaluation by two independent observers. Patients who had undergone previous spinal surgery had a significant improvement in functional outcome in terms of daily activity, work and leisure-time activities and anxiety/depression. With regard to social functioning, a significantly inferior outcome was found after the salvage procedure. The return-to-work rates at 2 years after surgery were 50% in the salvage group and 53% in the referent group. There was a significant correlation between radiological evaluation of the fusion mass and the functional outcome. The fusion rate was 76% in the salvage group and 72% in the referent group. This study demonstrates that a posterolateral spinal fusion can be effectively used as a salvage procedure. The functional and radiological outcome of the patients with revision surgery did not differ from those of the group of patients who underwent primary surgery. There was, however a clear indication of inferior social functioning after revision surgery.

The effect of indocyanine-green on functional outcome of macular pucker surgery.

PURPOSE: To compare functional results after surgery for macular pucker either with or without indocyanine-green staining of the internal limiting membrane (ILM) and to evaluate the ultrastructure of the tissue removed. DESIGN: Retrospective analysis of two successive, consecutive, interventional case series. METHODS: Functional outcome (visual acuity, Goldmann perimetry) of 48 eyes of 48 consecutive patients with (group 1, n = 20) or without (group 2, n = 28) intraoperative use of indocyanine-green (ICG) was retrospectively analyzed. For statistical analysis, best-corrected visual acuity measured at the last presentation was considered. Only patients with an idiopathic macular pucker were included. Surgery consisted of three-port pars plana vitrectomy, and removal of epiretinal tissue and the ILM in a second step. Commercially available ICG with a concentration of.05% and an osmolarity of 275 mOsm was used to stain the ILM. The surgical technique used for both groups was identical, except the use of ICG. Epiretinal tissue of all eyes was harvested and prepared for ultrastructural analysis using light and electron microscopy. RESULTS: Follow-up time was 8.5 months in group 1 and 5.4 months in group 2. Whereas patients operated on without ICG experienced a significant improvement of median best-corrected visual acuity from 20/63 (range, 20/400 to 20/32) preoperatively to 20/40 (range, 20/200 to 20/25) postoperatively (P < .001), median best-corrected visual acuity remained 20/63 before (range, 20/200 to 20/63) and after (range, 20/400 to 20/20) (P > .9) ICG-assisted peeling. There was a statistically significant difference (P = .013) in best-corrected postoperative visual acuity of patients with and without the use of ICG. An improvement of vision was noted in 86% of patients without and 55% of patients with ICG-assisted surgery. Thirty-five percent of patients after ICG application presented with a deterioration of visual acuity. Furthermore, we observed large visual field defects in 7 of 20 patients after ILM staining. No visual field defects were noted after conventional peeling. Histologic analysis revealed clear differences between the two groups concerning the amount of cellular elements adjacent to the retinal surface of the ILM: There was more cellular debris visible in specimens after ICG application during surgery. Additionally, in contrast to surgery without ILM staining, epiretinal cells had ruptured and lost their cellular integrity after ICG-assisted vitrectomy. CONCLUSIONS: Indocyanine green-assisted surgery for macular pucker might have an adverse effect on functional outcome. Although there were obvious differences in the ultrastructure of tissue removed during surgery, our observations cannot be explained by histologic analysis alone. Other, so far unknown mechanisms of action must be considered.

Measuring functional outcome in paediatric patients with burns: methodological considerations.

Methodological criticisms of research undertaken in the area of paediatric burns are widespread. To date, quasi-experimental research designs have most frequently been used to examine the impact of impairments such as scarring and reduced range of motion on functional outcomes. Predominantly, these studies have utilised a narrow definition of functioning (e.g. school attendance) to determine a child's level of participation in activities post-burn injury. Until recently, there had been little attempt to develop and/or test a theoretical model of functional outcome with these children. Using a conceptual model of functional outcome based on the International Classification of Functioning, Disability and Health, this review paper outlines the current state of the research literature and presents explanatory case study methodology as an alternative research design to further advance the study of functional outcome post-burn injury.

Functional outcome after surgical treatment of intramedullary spinal cord tumors: experience with 78 patients.

OBJECTIVE: To analyze factors with impact on the functional outcome for patients with surgically treated intramedullary spinal cord tumors (IMSCT) and to point out characteristics of the different histological entities. SETTING: Neurosurgical Department, University of Essen, Germany. METHODS: Between 1990 and 2000, a consecutive series of 78 patients were referred to our institution and underwent surgical treatment. There were 46 (59%) male and 32 (41%) female patients. Mean age was 43.3 years. Functional outcome was analyzed depending on histological features, age, tumor localization and the extension of involved spinal segments. The mean follow-up period was 34.4 months. Operative removal of the IMSCT was performed under standard microsurgical conditions with intraoperative monitoring of somatosensory-evoked potentials (SSEP). RESULTS: The most frequently involved localization was the cervical and cervicothoracic region (55%) followed by the thoracic region (32%) and the medullar conus (13%). The most frequent IMSCTs were neuroepithelial tumors in 44 patients (56.5%) including 32 patients with ependymomas, 15 astrocytomas, and two lesions without further histological classification. Non-neuroepithelial tumors included 10 metastases, nine cavernomas, eight hemangioblastomas, one dermoidal cyst and one enterogenetic cyst. Complete tumor removal was achieved in 65 cases (83.3%) and subtotal resection in nine cases. In four cases a biopsy was performed only. The overall postoperative neurological state was improved or unchanged in 51 patients (65.4%) and worsened in 27 patients (34.6%). A favorable functional outcome was observed in 94.1% of patients with vascular tumors, in 61.3% of patients with low-grade neuroepithelial tumors and in 53.3% of patients with malignant tumors. CONCLUSIONS: The strongest predicting factor of functional outcome was the preoperative neurological condition beyond the histological differentiation of the IMSCT. Although there was no outcome difference with respect to the age and tumor extension, thoracically located IMSCTs proved to harbor an increased risk of postoperative surgical morbidity.

Functional outcome after low-grade astrocytoma treatment in childhood.

BACKGROUND: The relatively high survival rate of patients with low-grade astrocytoma necessitates increasing attention to physical and psychosocial outcomes. The objective of the current study was to investigate functional outcomes among children who were treated for low-grade or pilocytic astrocytoma in different areas of the brain. METHODS: Functional outcomes were evaluated in the following domains: impairments, disabilities, handicaps, and quality of life (QOL). In a consecutive series, 38 children were included. Follow-up ranged from 3 years and 7 months to 11 years and 4 months after diagnosis. RESULTS: Approximately 61% of children had impairments and 10% had a severe disability. Handicaps were found in the domains of relationships, school, and behavior. Children who were treated for supratentorial tumors required significantly more special education, and children who were treated for infratentorial tumors had significantly more behavioral and social problems. QOL was decreased significantly in all domains except emotions. Children who had a diagnosis in adolescence reported a lower QOL in social functioning compared with younger children. Data analysis revealed that some deficits suddenly became apparent years after diagnosis. CONCLUSIONS: At long-term follow-up, children who had low-grade or pilocytic astrocytomas were found to have poor functional outcomes, depending on tumor site, age, and recurrence. Children without deficits may develop severe cognitive, social, and behavioral deficits years after diagnosis, because of the phenomenon of "growing into deficit." Therefore, the authors suggest a long-term follow-up of children who are treated for low-grade or pilocytic astrocytomas at a young age to detect and subsequently offer support focused on the medical and cognitive impairments as well as on the behavioral and social consequences of their disease.

Co-morbidity adjustment for functional outcomes in community-dwelling older adults.

OBJECTIVE: To characterize relationships between self-reported co-morbidity and functional outcomes in community-dwelling older adults, and to assess whether the impact of co-morbidity persists even after adjustment for baseline functional status. DESIGN: Prospective observational study. We examined associations between self-reported co-morbidity at baseline and functional outcomes at one year, with and without adjustment for baseline functional status. SETTING: Outpatient clinics at a managed care and a Veterans Affairs site. SUBJECTS: Four hundred and fifty-seven community-dwelling older adults representing a broad spectrum of overall health status. MAIN OUTCOME MEASURES: (a) New basic ADL (activities of daily living) problem during follow-up; (b) 10-point decline in the physical function index of the MOS-36 (MOS-PFI). RESULTS: Co-morbidity was associated with adverse functional outcomes in bivariable analyses. After adjustment for age and baseline functional status, an accumulated co-morbidity score provided additional explanatory power for predicting new ADL problems; odds ratios were 2.30 (1.09, 5.09) and 2.96 (1.48, 6.25) for 2 and > or = 3 affected co-morbidity domains, respectively. The impact of baseline status was also important; odds ratios for new ADL problems were 4.77 (2.68, 8.81) when at least one instrumental activity of daily living (IADL) problem was present at baseline, and 15.6 (8.05, 31.3) when at least one basic ADL problem was present at baseline. CONCLUSIONS: Accumulated self-reported co-morbidity has significant negative effects on function at one year; these effects are attenuated but not eliminated by adjustment for baseline status. Co-morbidity adjustment is probably an important design element in clinical research focused on functional outcomes in older adults.

Determinants of the subjective functional outcome of total joint arthroplasty.

The aim of the study is three-fold: (i) to analyze association between early subjective functional outcome of total joint arthroplasty (TJA) and patient-related risk factors; (ii) to evaluate the six-month subjective functional outcome of TJA as compared with subjective functional status of non-operated outpatients; (iii) to evaluate TJA self-perceived amelioration rates compared to the status of an age-matched sample from a general medical practice. A prospective consecutive study was performed upon 100 elderly inpatients with recent primary total hip arthroplasty (THA) or total knee arthroplasty (TKA) for osteoarthritis. Interviews on preoperative status and short-term outcome were performed at admission and six months after surgical intervention with Western Ontario and MacMasters Universities Osteoarthritis Index (WOMAC). One hundred aged-matched consecutive outpatients were screened for osteoarthritis and interviewed with the same questionnaire in a single session. Differences between baseline and follow-up scores were evident and statistically significant for both TJA groups, although THA patients showed more improvement. The comparison between TJA patients at baseline and age-matched osteoarthritis outpatients highlighted less impairment among outpatients. The situation reversed six months after the intervention. Objective functional outcome of post-operative rehabilitation has not revealed predictive value for the six-month outcome of TJA in terms of self-perceived functional status. Logistic regression analysis indicated that preoperative status was the only significant predictor of higher WOMAC scores six months after TJA. The survey confirms the early benefit of THA or TKA for osteoarthritis, but a less favorable subjective functional outcome is expected at six months when preoperative subjective functional status is severely compromised.
