Application of the Staged Approach for Rehabilitation Classification System and Associated Improvements in Patient-Reported Outcomes Following Rehabilitation for Shoulder Pain

OBJECTIVE

The Staged Approach for Rehabilitation Classification for the Shoulder (STAR-Shoulder) has been proposed as a model to guide management and improve outcomes for patients with shoulder pain, however, the effect of its utilization on patient outcomes has not been established. Therefore, the primary purpose of this study was to determine whether patient outcomes were improved if care was matched to the STAR-Shoulder system compared to unmatched care.

METHODS

Collected and reviewed demographic, examination, and intervention data for all patients receiving physical therapist treatment for shoulder pain during a 1-year period within a single health care system. Outcome variables included the numeric pain rating scale, the Quick Disabilities of the Arm, Shoulder and Hand Questionnaire (QuickDASH), and the number of visits. Clinical records from patients receiving care at the discretion of the therapist were systematically audited to determine whether care provided was considered matched or unmatched.

RESULTS

A total of 692 patient records were examined. The interrater reliability of classifying care as matched or unmatched was substantial (κ = 0.6; 95% CI = 0.4 to 0.9), with 82% agreement. Changes in patient outcome scores were significantly better for those patients whose care matched the STAR-Shoulder system for pain changes (mean difference = -1.2; 95% CI = 0.8 to 1.6; effect size [d] = 0.5) and QuickDASH score (mean difference = 12.7; 95% CI = 9.9 to 15.5; d = 0.7). No difference was noted for number of visits.

CONCLUSION

The STAR-Shoulder system appears to be a meaningful way to classify patients and guide intervention to improve patient outcomes.

IMPACT

Application of the STAR-Shoulder system to help align physical therapist interventions more closely with tissue irritability and physical impairments appears to improve patient outcomes. These findings support this model as a promising approach to advance evidence-based practice for shoulder pain.

Inpatient Mortality Benefit with Transjugular Intrahepatic Portosystemic Shunt for Hospitalized Hepatorenal Syndrome Patients

BACKGROUND

It has been reported that transjugular intrahepatic portosystemic shunting (TIPS) might be utilized as a salvage option for hepatorenal syndrome (HRS), while randomized controlled trials are pending and real-world contemporary data on inpatient mortality is lacking.

METHODS

We conducted an observational retrospective cohort study from the National Inpatient Sample from 2005 to 2014. We included all adult patients admitted with HRS and cirrhosis, using ICD 9-CM codes. We excluded cases with variceal bleeding, Budd-Chiari, end-stage renal disease, liver transplant and transfers to acute-care facilities. TIPS' association with inpatient mortality was assessed using multivariable mixed-effects logistic regression, as well as exact-matching, thus mitigating for TIPS selection bias. The exact-matched analysis was repeated among TIPS-only versus dialysis-only patients.

RESULTS

A total of 79,354 patients were included. Nine hundred eighteen (1.2%) underwent TIPS. Between TIPS and non-TIPS groups, mean age (58 years) and gender (65% males) were similar. Overall mortality was 18% in TIPS and 48% in dialysis-only cases (n = 10,379; 13.1%). Ninety six (10.5%) TIPS patients underwent dialysis. In-hospital mortality in TIPS patients was twice less likely than in non-TIPS patients (adjusted odds ratio [aOR] = 0.43, 95% CI 0.30-0.62; p < 0.001), with similar results in matched analysis [exact-matched (em) OR = 0.39, 95% CI 0.17-0.89; p < 0.024; groups = 96; unweighted n = 463]. Head-to-head comparison showed that TIPS-only patients were 3.3 times less likely to succumb inpatient versus dialysis-only patients (contrast aOR = 0.31, 95% CI 0.20-0.46; p < 0.001), with similar findings post-matching (emOR = 0.22, 95% CI 0.15-0.33; p < 0.001; groups = 54, unweighted n = 1457).

CONCLUSIONS

Contemporary, real-world data reveal that TIPS on its own, and when compared to dialysis, is associated with decreased inpatient mortality when utilized in non-bleeders-HRS patients. Further randomized studies are needed to establish the long-term benefit of TIPS in these patients.

Determinants of acute respiratory infection (ARI) among under-five children in rural areas of Legambo District, South Wollo Zone, Ethiopia: A matched case-control study

BACKGROUND

Acute respiratory infection (ARI) leads to morbidity and mortality among under-fivechildren in developing countries, especially in rural settings. ARI ranks among the top 10 diseases in under-five children in Legambo District, South Wollo Zone, Ethiopia. The aim of this study was to evaluate determinant factors for ARI in Legambo District in 2019.

MATERIALS AND METHODS

A community-based matched case-control study was conducted, involving 139 cases and 278 controls under 5 years of age, from mid-January to mid-February 2019. Data were collected using a structured questionnaire. Bivariate and multivariable conditional logistic regression analyses were performed. From the multivariable conditional logistic regression analysis, variables with a significance level of p < 0.05 were taken as significantly associated with ARI among under-five children.

RESULT

ARI among children under 5 years of age was significantly associated with age of the mother/caregiver being ≥35 years, occupation of mother/caregiver being housewife, the family being of medium wealth status, the type of stove used in the house, carrying the child while preparing food, absence of windows in the house, and nutritional status of the child.

CONCLUSION

The occurrence of ARI could be reduced by improving economic status, stove use, and nutrition of children, and by increasing community awareness regarding indoor air pollution and ventilation.

Which factors influence the development of GVHD in HLA-matched or mismatched transplants?

The sheer diversity of HLA alleles makes the probability of finding matched unrelated donors for patients requiring hematopoietic cell transplantation (HCT) a complex situation. New evidence suggests that mismatching at certain HLA loci may provide a greater benefit in terms of graft-versus-leukemia effect than other mismatches when HLA-matched donors are not available. This review summarizes the current understanding of HLA matching requirements for unrelated donor HCT.

Sequential matched analysis of racial disparities in breast cancer hospitalization outcomes among African American and White patients

BACKGROUND

The purpose of this study is to determine if racial disparities in inpatient outcomes persist among hospitalized patients comparing African American and White breast cancer patients matched on demographics, presentation and treatment.

METHODS

A total of 136,211 African American and White breast cancer patients from the Healthcare Cost and Utilization Project - Nationwide Inpatient Sample (HCUP-NIS) database, matched on demographics alone, demographics and presentation or demographics, presentation and treatment were studied. Conditional logistic regression was conducted to evaluate post-surgical complications, length of stay and in-hospital mortality outcomes. Analysis was further stratified by age (≤65 years and >65years) to evaluate whether disparities were larger in younger or older patients. All analysis was conducted using SAS 9.3.

RESULTS

White women had significantly shorter hospital length of stay when matched on demographics (β=-0.87, p-value=<0.0001), demographics and presentation (β=-0.63, p-value=<0.0001), and demographics, presentation and treatment (β=-0.51, p-value=<0.0001) compared with African Americans. White women also had lower odds of mortality compared with African American women when matched on demographics (OR: 0.72, 95% CI: 0.65-0.79), demographics and presentation (OR: 0.77, 95% CI: 0.71-0.85), or matched on demographics, presentation and treatment (OR: 0.80, 95% CI: 0.73-0.88). The racial difference observed in length of stay and mortality was larger in the age group ≤65 years compared with >65years CONCLUSION: African American women experienced higher odds of inpatient mortality and longer length of stay compared with White women even after accounting for differences in demographics, presentation and treatment characteristics.

Associations between human exposure to polybrominated diphenyl ether flame retardants via diet and indoor dust, and internal dose: A systematic review

The aim of this review was to identify and appraise the current international evidence of associations between concentrations of polybrominated diphenyl ethers (PBDEs) in humans and their indoor dusts and food. We systematically searched Medline, Embase, Web of Science and Scopus (up to Jan 2015), using a comprehensive list of keywords, for English-language studies published in peer-reviewed journals. We extracted information on study design, quality, participants, sample collection methods, adjustments for potential confounders and correlations between PBDE concentrations in internal and external matrices. Of 131 potential articles, 17 studies met the inclusion criteria and were included in the narrative synthesis. We concluded that three key factors influenced correlations between external and internal PBDE exposure; half-life of individual congeners in the human body; proximity and interaction between PBDE source and study subject; and time of study relative to phase out of PBDE technical products. Internal dose of Penta-BDE technical mix congeners generally correlated strongly with dust. The exception was BDE-153 which is known to have higher persistence in human tissues. Despite the low bioaccessibility and short half-life of BDE-209, its high loading in dusts gave strong correlations with body burden where measured. Correlations between PBDE concentrations in duplicate diet and body burden were not apparent from the included studies. Whether dust or diet is the primary exposure source for an individual is tied to the loading of PBDE in dust or food items and the amounts ingested. Simple recommendations such as more frequent hand washing may reduce PBDE body burden.

How Does Brainstem Involvement Affect Prognosis in Patients with Limited Brain Metastases? Results of a Matched-Cohort Analysis

OBJECTIVE

Although brainstem metastases are thought to portend an inferior prognosis compared to non-brainstem brain metastases, there is limited evidence to support this claim, particularly in the modern radiosurgical era.

METHODS

We collected the clinical data for 500 patients with brain metastases treated at our institution with stereotactic radiosurgery (SRS). All patients received SRS to at least one brain metastasis, and all brainstem metastases underwent SRS. After propensity score matching, clinical characteristics and overall survival were calculated and compared between groups.

RESULTS

Three hundred sixteen patients with brain metastases were analyzed after matching (143 with brainstem involvement and 173 without). Patients with brainstem metastases lived shorter after first SRS than patients without brainstem metastases did (median 4.4 and 6.5 months, respectively; P = 0.01), and they were more likely to have received whole brain irradiation (P = 0.003). Patients with a single metastasis did not survive longer than patients with multiple brain metastases if there was brainstem involvement (P = 0.45). The incidence of new extracranial disease and severe toxicity after SRS did not differ between groups.

CONCLUSIONS

The survival of patients with brain metastases is inferior after a metastatic lesion develops within the brainstem, despite favorable local control with brainstem SRS. The brainstem location should be considered a negative prognostic factor for survival after SRS, and it could result from the eloquence of this location. Future research could identify the clinically life-limiting component of brainstem metastases.

Clinical outcome following conversion of Girdlestone's resection arthroplasty to total hip replacement: a retrospective matched case-control study

A total of 31 patients, (20 women, 11 men; mean age 62.5 years old; 23 to 81), who underwent conversion of a Girdlestone resection-arthroplasty (RA) to a total hip replacement (THR) were compared with 93 patients, (60 women, 33 men; mean age 63.4 years old; 20 to 89), who had revision THR surgery for aseptic loosening in a retrospective matched case-control study. Age, gender and the extent of the pre-operative bone defect were similar in all patients. Mean follow-up was 9.3 years (5 to 18). Pre-operative function and range of movement were better in the control group (p = 0.01 and 0.003, respectively) and pre-operative leg length discrepancy (LLD) was greater in the RA group (p < 0.001). The post-operative clinical outcome was similar in both groups except for mean post-operative LLD, which was greater in the study group (p = 0.003). There was a significant interaction effect for LLD in the study group (p < 0.001). A two-way analysis of variance showed that clinical outcome depended on patient age (patients older than 70 years old had worse pre-operative pain, p = 0.017) or bone defect (patients with a large acetabular bone defect had higher LLD, p = 0.006, worse post-operative function p = 0.009 and range of movement, p = 0.005), irrespective of the group. Despite major acetabular and femoral bone defects requiring complex surgical reconstruction techniques, THR after RA shows a clinical outcome similar to those obtained in aseptic revision surgery for hips with similar sized bone defects.
