The handgrip strength threshold of 16 kg discriminates successful rehabilitation: A prospective short-term study of 258 women with hip fracture

Survey on diagnosis of post-brain injury "higher brain dysfunction" in patients with cognitive impairment. Family/caregiver response

In Japan, the diagnostic criteria for the higher brain dysfunction (HBD) emerged in 2005 in response to social needs for support for the patients and their families. The issue of cognitive dysfunction after brain trauma is not unique to Japan. The purpose of this study was to reveal the current status of family members of HBD patients from their perspective, focusing on the changes before and after the establishment of diagnostic criteria in Japan. We conducted a questionnaire survey for family members supporting the HBD patients. The questionnaire included the causative condition, explanation on HBD by health professionals, and problems/difficulties they encountered. This research involved family members of 278 HBD cases (males = 211, age 49 years). The major underlying cause was head injury (n = 139). Compared to patients diagnosed pre-2005, a significantly larger proportion of family members after 2005 received information on the condition during the acute phase (within one month) (p < 0.001), including that from physicians (p < 0.001). Nearly half of the families cited a lack of awareness of HBD among the professionals as a problem. In Japan, awareness of HBD in the society is gradually increasing especially after the current diagnostic criteria were implemented, and there has been a steady increase over time in early diagnosis. Yet, there still remain those not appropriately diagnosed. To salvage those patients and the families left behind, we are suggesting several recommendations to further augment clinical practice and the healthcare systems in Japan.

Cognitive assessment to optimize prediction of functional outcome in subacute hip fracture: a short-term prospective study

BACKGROUND

Cognitive impairment is a long-known negative prognostic factor after hip fracture. Cognition is usually screened by a single easy-to-administer bedside tool, but recent studies have shown that screening tests may be not enough to rule out cognitive impairment with an unfavorable prognostic role. Unfortunately, data on outcome prediction by further cognitive assessments is sparse.

AIM

We focused on patients with subacute hip fracture defined cognitively intact or mildly impaired on the screening evaluation performed by the Short Portable Mental Status Questionnaire (SPMSQ). We hypothesized that each of 3 further cognitive tests could independently predict activities of daily living, with optimal prediction of function obtained by performing all three the tests.

DESIGN

Short-term prospective study.

SETTING

Rehabilitation ward.

POPULATION

Inpatients with subacute hip-fracture.

METHODS

Three cognitive tests were performed on admission to rehabilitation in the patients who made ≤4 errors on the SPMSQ: Montreal Cognitive Assessment (MoCA), Rey Auditory Verbal Learning Test (RAVLT, immediate and delayed recall) and Frontal Assessment Battery (FAB). We assessed activities of daily living by the Barthel index. Successful rehabilitation was defined with a Barthel Index Score ≥85.

RESULTS

Each of the three cognitive tests assessed before rehabilitation significantly predicted the Barthel index scores measured at the end of the rehabilitation course in our sample of 280 inpatients. However, only the MoCA score retained its significant predictive role when the scores from the three tests were included together as independent variables in a multiple regression model, with adjustments for a panel of potential confounders (P=0.007). The adjusted odds ratio to achieve successful rehabilitation for a seven-point change in MoCA score was 1.98 (CI 95% from 1.02 to 3.83; P=0.042).

CONCLUSIONS

Contrary to our hypothesis, MoCA but not RAVLT and FAB retained the prognostic role when the scores from the three tests were evaluated together as potential predictors of functional ability in activities of daily living.

CLINICAL REHABILITATION IMPACT

In the presence of a normal (or mildly altered) score on the SPMSQ in subacute hip fracture, MoCA scores improve prediction of activities of daily living and should be routinely performed.

Pertrochanteric hip fracture is associated with mobility decline and poorer physical performance 4 to 6 months post-hip fracture

BACKGROUND

To study the effect of hip fracture type on physical performance, functional ability and change in mobility four to six months after the injury.

METHODS

A total of 1331 patients out of consecutive 2052 patients aged ≥ 65 years who underwent hip fracture surgery were included in the study. Patient information was collected on admission, during hospitalization, by phone interview and at the geriatric outpatient clinic 4 to 6 months after the fracture. Of the 1331 eligible patients, Grip strength, Timed Up and Go -test (TUG), Elderly Mobility Scale (EMS), mobility change compared to pre-fracture mobility level, Basic Activities of Daily Living (BADL) and Instrumental Activities of Daily Living (IADL) were used to determine physical performance and functional ability. Logistic regression was used for the analyses which was adjusted for gender, age, American Society of Anesthesiologists score, diagnosis of cognitive disorder, pre-fracture living arrangements, mobility and need of mobility aid.

RESULTS

Patients with pertrochanteric hip fracture had an EMS lower than 14 (Odds Ratio (OR) 1.38, 95% confidence intervals (CI) 1.00-1.90), TUG time ≥ 20 s (OR 1.69, 95% CI 1.22-2.33) and they had declined in mobility (OR 1.58, 95% CI 1.20-2.09) compared to femoral neck fracture patients 4 to 6 months post-hip fracture in multivariable-adjusted logistic regression analyses. Grip strength and functional ability (IADL, BADL) 4 to 6 months after hip fracture did not differ between fracture types. There were no statistically significant differences in physical performance in patients with a subtrochanteric fracture compared to patients with a femoral neck fracture.

CONCLUSIONS

Pertrochanteric hip fracture independently associated with poorer physical performance 4 to 6 months post hip fracture compared to other hip fracture types. Pertrochanteric hip fracture patients should be given special attention in terms of regaining their previous level of mobility.

A screening test is not enough to define the prognostic role of cognitive impairment after hip fracture: a short-term prospective study

BACKGROUND

Cognitive impairment assessed by easy-to-administer tests successfully predicts function after hip fracture, whereas the prognostic role of additional cognitive evaluations is largely unknown.

AIMS

To investigate the capability of further assessments to discriminate cognitive impairment with prognostic relevance in hip-fracture women defined cognitively intact or mildly impaired on the Short Portable Mental Status Questionnaire (SPMSQ).

METHODS

We prospectively investigated women with subacute hip fracture admitted to our rehabilitation facility. The women who made ≤4 errors on the SPMSQ were further assessed by 4 tests: Montreal Cognitive Assessment, Rey Auditory Verbal Learning Test (immediate and delayed recall) and Frontal Assessment Battery. Activities of daily living (ADL) were measured by the Barthel index. Successful rehabilitation was defined with a Barthel index score ≥85.

RESULTS

Data from 127 women were available. Each of the 4 cognitive tests assessed at admission significantly predicted the Barthel index scores measured at discharge. The predictive role persisted after multiple adjustments. For a change in cognitive scores corresponding to the difference between 25° and 75° percentiles in their distribution in the sample, the adjusted odds ratio to achieve successful rehabilitation roughly ranged from 2 to 4, depending on which cognitive test was adopted.

DISCUSSION

The women with subacute hip fracture defined cognitively intact or mildly impaired on the SPMSQ could have cognitive impairment revealed by further examination, with prognostic disadvantages in ADL.

CONCLUSIONS

Assessing cognition by the SPMSQ seems not enough to exclude the presence of cognitive impairment with relevant prognostic disadvantage in hip-fracture women.

Handgrip Strength as a Predictor of Successful Rehabilitation After Hip Fracture in Patients 65 Years of Age and Above

Purpose

It is important to identify factors associated with the outcome of rehabilitation after hip fracture as an aid to planning the rehabilitation framework and the future discharge of patients. Previous studies have shown that handgrip strength (HGS) is one of the factors associated with the success of rehabilitation.

Materials and Methods

A retrospective study among patients 65 years of age and above who underwent surgical repair of a hip fracture followed by rehabilitation in the Geriatrics ward between September 2019 and December 2021. Successful rehabilitation was determined as Montebello Rehabilitation Factor Score Revised (MRFS-R) ≥50%. Associations were assessed between various sociodemographic and clinical variables, including HGS, and rehabilitation success. HGS was tested as a continuous and dichotomous variable, in accordance with various definitions of low muscle strength.

Results

Data were collected for 173 patients. The mean age was 81.2 ± 7.2 years and 68.2% were women. In a logistic regression model only HGS, as a continuous variable, was independently associated with rehabilitation success, with each increase of 1 kg increasing the chance for successful rehabilitation by 6.8%.

Conclusion

HGS is a simple tool for the planning of the rehabilitation process among patients with hip fracture.
