Reliability and clinical utility of a novel telehealth-based goniometry approach to measure range of motion of the digits of the hand

BACKGROUND

Range of motion (ROM) is an outcome measure commonly used when treating acute and chronic hand injuries and conditions. Increased adoption of telehealth service provision in hand therapy practice, influenced by the advent of COVID-19, has led to the need for a valid and reliable approach to measure the range of motion of the digits of the hand when providing hand therapy services using telehealth.

PURPOSE

To determine if performing manual goniometry during a livestream teleconsultation is reliable and clinically useful to measure the range of motion of the fifth digit when providing hand therapy services using telehealth.

STUDY DESIGN

Clinical measurement, repeated-measures study.

METHODS

According to a measurement protocol, 12 independent raters (who currently provide hand therapy services) each obtained several screen-based goniometric range of motion measurements of the fifth digit at 2-time points. Raters were surveyed on the clinical utility of the telehealth-based goniometry approach. Measures of relative and absolute reliability were calculated to evaluate test-retest and inter-rater reliability. Free-text responses were analyzed using content analysis.

RESULTS

Inter-rater reliability was excellent for all flexion and extension measures (intraclass correlation coefficient [ICC] ≥ 0.89) but poor for the arc of motion (ICC ≤ 0.67). Test-retest reliability was poor (ICC ≤ 0.43). No statistically significant differences between test and retest measurements were observed (P ≥ 0.24). The overall coefficient of variation indicated good precision (14.69%). Measurement error (≤6.07º) and limits of agreement (≤6.33) had acceptable levels to support clinical use. Content analysis revealed several practical considerations.

CONCLUSIONS

This study suggests that performing manual goniometry during a livestream teleconsultation is unreliable for measuring the range of motion of the fifth digit. However, when combined with patient-reported and functional outcomes, this approach may be suitable to facilitate a range of motion assessment for certain functions of telehealth service provision in hand therapy practice.

Cost, profile, and postoperative resource use for surgically managed acute hand and wrist injuries with emergency department presentation

STUDY DESIGN

Retrospective cost-of-illness study.

INTRODUCTION

Injuries to the hand and wrist are common. Most uncomplicated and stable upper extremity injuries recover with conservative management; however, some require surgical intervention. The economic burden on the health care system from such injuries can be considerable.

PURPOSE OF THE STUDY

To estimate the economic implications of surgically managed acute hand and wrist injuries at one urban health care network.

METHODS

Using 33 primary diagnosis ICD-10 codes involving the hand and wrist, 453 consecutive patients from 2014 to 2015 electronic billing records who attended the study setting emergency department and received consequent surgical intervention and outpatient follow-up were identified. Electronic medical records were reviewed to extract demographic data. Costs were calculated from resource use in the emergency department, inpatient, and outpatient settings. Results are presented by demographics, injury type, mechanism of injury, and patient pathway.

RESULTS

Two hundred and twenty-six individuals (n 1⁄4 264 surgeries) were included. The total cost of all injuries was $1,204,606. The median cost per injury for non-compensable cases (n = 191) was $4508 [IQR $3993-$6172] and $5057 [IQR $3957-$6730] for compensable cases (n = 35). The median number of postoperative appointments with a surgeon was 2.00 (IQR 1.00-3.00) for both compensable and non-compensable cases. The number of hand therapy appointments for non-compensable cases and compensable cases was 4 [IQR 2-6] and 2 [IQR 1-3], respectively.

DISCUSSION

Findings of this investigation highlight opportunities for health promotion strategies for reducing avoidable injuries and present considerations for reducing cost burden by addressing high fail to attend (FTA) appointment rates.

CONCLUSION

Surgically managed hand and wrist injuries contribute to a significant financial burden on the health care system. Further research using stringent data collection methods are required to establish epidemiological data and national estimates of cost burden.

Capturing the costs of acute hand and wrist injuries: Lessons learnt from a prospective longitudinal burden of injury study

Introduction

Given the high incidence of hand and wrist injuries, they are exceptionally costly to the economy. This prospective, longitudinal study aimed to establish methods for capturing the burden of acute hand and wrist injury from an individual and societal perspective.

Methods

A prospective longitudinal design with baseline measures of injury type and severity, and repeated measures of disability, cost, and activity limitations and participation restrictions at six weeks, three months, and six months was selected. Participants were recruited from two large urban Australian public health care services. We sought to establish methods for capturing the burden of acute hand and wrist injury from an individual and societal perspective and compare survey completion by the method of administration.

Results

A total of 206 patients consented to participate in this study, representing 54% of those invited to participate. The survey completion rates were 18% at six weeks, 2.4% at twelve weeks, and 0.004% at six months following injury. From the limited data collected at six weeks, it was noted that nearly half of the patients reported a decrease in usual financial income, 14% reported absenteeism, and 62% reported presenteeism. Participants who elected to have data collected via phone call had the highest survey completion rate ( n = 6/10; 30%) at six-week’s follow-up.

Discussion

The study findings highlight the difficulties of completing longitudinal survey research investigating individual and societal burden with this population. Future research should be carefully designed to encourage participation and retention by considering patient and public involvement in study design, the time burden placed on the participants within and across selected survey time points, providing participants with incentives to participate, and highlighting the relevance and real-world applications of the findings.

Profile and cost of sport and exercise-related hand and wrist injuries with Emergency Department presentation

OBJECTIVES

Injuries to the hand and wrist from sport and exercise are common and costly. This cost-of-illness analysis was performed to estimate the economic implications of hand and wrist injuries that were sustained as a result of participation during sport or exercise.

PERSPECTIVE

Cost estimates were calculated from resource use in the emergency, inpatient and outpatient settings from the perspective of one public healthcare service.

SETTING

Alfred Health, a large public health service with two emergency departments located in Victoria, Australia.

METHODS

This descriptive epidemiological study used ICD-10 diagnostic codes and electronic billing records to identify 778 potential cases for inclusion. Electronic medical records were screened and reviewed to extract demographic and patient care journey data.

RESULTS

692 individuals, (n=761 individual zone of injuries), were included. Australian Rules Football (ARF) was the largest contributor to injuries (20.2%) followed by riding bicycles (15.9%. The total cost of all injuries was $790,325, with a median cost per case of $278 [IQR $210-$282] in the Emergency Department n=692, $3328 [IQR $2242-$6441] in the inpatient setting n=76 and $630 [IQR $460-$870] in the outpatient setting n=244.

CONCLUSIONS

Hand and wrist injuries sustained from sport and exercise contribute to a significant financial burden on the healthcare system. Future research that considers the costs that occur outside of the public healthcare service is required estimate the burden associated with these injuries comprehensively. Injury prevention programs may mitigate the observed injury trends.

Direct, indirect and intangible costs of acute hand and wrist injuries: A systematic review

BACKGROUND

Injuries sustained to the hand and wrist are common, accounting for 20% of all emergency presentations. The economic burden of these injuries, comprised of direct (medical expenses incurred), indirect (value of lost productivity) and intangible costs, can be extensive and rise sharply with the increase of severity.

OBJECTIVE

This paper systematically reviews cost-of-illness studies and health economic evaluations of acute hand and wrist injuries with a particular focus on direct, indirect and intangible costs. It aims to provide economic cost estimates of burden and discuss the cost components used in international literature.

MATERIALS AND METHODS

A search of cost-of-illness studies and health economic evaluations of acute hand and wrist injuries in various databases was conducted. Data extracted for each included study were: design, population, intervention, and estimates and measurement methodologies of direct, indirect and intangible costs. Reported costs were converted into US-dollars using historical exchange rates and then adjusted into 2015 US-dollars using an inflation calculator RESULTS: The search yielded 764 studies, of which 21 met the inclusion criteria. Twelve studies were cost-of-illness studies, and seven were health economic evaluations. The methodology used to derive direct, indirect and intangible costs differed markedly across all studies. Indirect costs represented a large portion of total cost in both cost-of-illness studies [64.5% (IQR 50.75-88.25)] and health economic evaluations [68% (IQR 49.25-73.5)]. The median total cost per case of all injury types was US$6951 (IQR $3357-$22,274) for cost-of-illness studies and US$8297 (IQR $3858-$33,939) for health economic evaluations. Few studies reported intangible cost data associated with acute hand and wrist injuries.

CONCLUSIONS

Several studies have attempted to estimate the direct, indirect and intangible costs associated with acute hand and wrist injuries in various countries using heterogeneous methodologies. Estimates of the economic costs of different acute hand and wrist injuries varied greatly depending on the study methodology, however, by any standards, these injuries should be considered a substantial burden on the individual and society. Further research using standardised methodologies could provide guidance to relevant policy makers on how to best distribute limited resources by identifying the major disorders and exposures resulting in the largest burden.

Use of panel tests in place of single gene tests in the cancer genetics clinic

Improved technology has made it possible to test for mutations within multiple genes simultaneously. It is not clear when these gene 'panels' should be used in the hereditary cancer setting. These analyses were intended to guide panel testing criteria. Offering hereditary panel testing as a first and final, 'single-tier', option was explored. A 'two-tiered' approach, in which panel testing is offered reflexively following stricter criteria, was then applied to the same data. Within our cohort of 105 patients, the single-tier approach was associated with a higher mutation detection rate (6.7% vs 3.8%) and variant of uncertain significance (VUS) rate (0.94 vs 0.23 average per person) compared to a two-tiered approach. Of the VUSs also identified in other patients by another lab, 53% were classified differently between laboratories. Individuals reporting African American race had more VUSs compared to other ancestry groups (p = 0.001). The test cost for a single-tier test was 21% more than a two-tiered approach. Single-tier panel testing was associated with higher mutation and VUS rates, and there is inconsistent classification of the VUS/low penetrant genes between laboratories.

SigE is a chaperone for the Salmonella enterica serovar Typhimurium invasion protein SigD

SigD is translocated into eucaryotic cells by a type III secretion system. In this work, evidence that the putative chaperone SigE directly interacts with SigD is presented. A bacterial two-hybrid system demonstrated that SigE can interact with itself and SigD. In addition, SigD was specifically copurified with SigE-His(6) on a nickel column.
