Surgical helmet systems in total joint arthroplasty: assessment of hood sterility and donning technique

BACKGROUND

The incidence of prosthetic joint infection (PJI) is increasing, coincident with the rising volume of joint arthroplasty being performed. With recent controversy regarding the efficacy of surgical helmet systems (SHS) in preventing infection, the focus has turned to the correct donning techniques and usage of surgical hoods. The aim of this study was to compare the bacterial contamination of the operating surgeon's gloves after two common donning techniques of SHS hoods. We also evaluated the baseline sterility of the SHS hoods at the beginning of the procedure.

METHODS

The bacterial contamination rate was quantified using colony-forming units (CFUs), with 50 trials performed per donning technique. Samples were cultured on 5% Columbia blood agar in ambient air at 37 °C for 48 h and all subsequent bacterial growth was identified using a MALDI-TOF mass spectrometer. In Group 1, the operating surgeon donned their colleague's hood. In Group 2, the operating surgeon had their hood applied by a non-scrubbed colleague. After each trial, the operating surgeon immediately inoculated their gloves onto an agar plate. The immediate sterility of 50 SHS hoods was assessed at two separate zones-the screen (Zone 1) and the neckline (Zone 2).

RESULTS

There was no significant difference in contamination rates between the two techniques (3% vs. 2%, P = 0.99) or between right and left glove contamination rates. Immediately after donning, 6/50 (12%) of SHS hoods cultured an organism. Contamination rates at both the face shield and neckline zones were equivalent. The majority of bacteria cultured were Bacillus species.

DISCUSSION

We found no significant difference in the operating surgeon's glove contamination using two common SHS hood-donning techniques when they were performed under laminar airflow with late fan activation. We suggest the SHS hood should not be assumed to be completely sterile and that gloves are changed if it is touched intraoperatively.

Return to Sport After Operative Fixation of Midshaft Clavicle Fractures in Professional Jockeys

OBJECTIVE

Clavicle fractures are the most commonly observed fracture sustained in professional horse racing. This study is the first to report on time lost from injury and functional recovery after surgical fixation of midshaft clavicle fractures in professional jockeys.

DESIGN

Retrospective cohort study.

SETTING

Professional Horse Racing Ireland; Patients (or Participants): Professional Jockeys in Ireland with midshaft clavicular fractures managed with Open Reduction Internal Fixation. Interventions (or Assessment of Risk Factors or Independent Variables): Operative fixation with Open Reduction Internal Fixation.

MAIN OUTCOME MEASURES

Assessment of postoperative Quick Disabilities of Arm Shoulder and Hand (QuickDASH) score and Patient Reported Outcome Measures assessing for associated complications and time to return to competition among professional athletes.

RESULTS

Between 07/06/2013 and 29/09/2022, 22 patients met the predetermined inclusion criteria. Ninety-five percent of patients returned to competition at their preinjury level, one patient failed to return to competition for reasons unrelated to his injury. The mean time for return to competition was 68.14 days postinjury. Few complications were reported, whereas functional recovery was excellent across the cohort, with an average QuickDASH score of 0.85 (0.0-2.3).

CONCLUSIONS

Plate fixation of midshaft clavicle fractures is effective and safe in the setting of professional horse racing. Ninety-five percent of patients can be expected to return within 14 weeks of injury. Patients returning at less than 7 weeks after injury had no adverse outcomes, suggesting a potential role for more aggressive rehabilitation postoperatively and ultimately, a quicker return to competition.

Readability of Patient Educational Materials in Sports Medicine

Background:

The internet has become an increasingly popular resource among sports medicine patients seeking injury-related information. Numerous organizations recommend that patient educational materials (PEMs) should not exceed sixth-grade reading level. Despite this, studies have consistently shown the reading grade level (RGL) of PEMs to be too demanding across a range of surgical specialties.

Purpose:

To determine the readability of online sports medicine PEMs.

Study Design:

Cross-sectional study.

Methods:

The readability of 363 articles pertaining to sports medicine from 5 leading North American websites was assessed using 8 readability formulas: Flesch-Kincaid Reading Grade Level, Flesch Reading Ease Score, Raygor Estimate, Fry Readability Formula, Simple Measure of Gobbledygook, Coleman-Liau Index, FORCAST Readability Formula, and Gunning Fog Index. The mean RGL of each article was compared with the sixth- and eighth-grade reading level in the United States. The cumulative mean website RGL was also compared among individual websites.

Results:

The overall cumulative mean RGL was 12.2 (range, 7.0-17.7). No article (0%) was written at a sixth-grade reading level, and only 3 articles (0.8%) were written at or below the eighth-grade reading level. The overall cumulative mean RGL was significantly higher than the sixth-grade [95% CI for the difference, 6.0-6.5; P < .001] and eighth-grade (95% CI, 4.0-4.5; P < .001) reading levels. There was a significant difference among the cumulative mean RGLs of the 5 websites assessed.

Conclusion:

Sports medicine PEMs produced by leading North American specialty websites have readability scores that are above the recommended levels. Given the increasing preference of patients for online health care materials, the imperative role of health literacy in patient outcomes, and the growing body of online resources, significant work needs to be undertaken to improve the readability of these materials.

Readability of patient education materials related to radiation safety: What are the implications for patient-centred radiology care?

Background

Increasing numbers of patients and carers rely on online resources for healthcare information. Radiation safety can be misunderstood by patients and clinicians and lead to patient anxiety. We aimed to assess the readability of online patient educational materials (PEMs) related to radiation safety.

Methods

A total of 84 articles pertaining to radiation safety from 14 well-known online resources were identified. PEMs were then analysed using Readability Studio Professional Edition Version 2019. Readability was assessed using eight different instruments: the Flesch-Kincaid Reading Grade Level, Raygor Estimate, SMOG, Coleman–Liau, Fry, FORCAST, Gunning Fog, and Flesch Reading Ease Score formula. The mean reading grade level (RGL) of each article was compared to the 6th and 8th grade reading level using 1-sample t-tests.

Results

The cumulative mean RGL for all 84 articles was 13.3 (range = 8.6–17.4), and none were written at or below the 6th or 8th grade level. The cumulative mean RGL exceeded the 6th grade reading level by an average of 7.3 levels (95% CI, 6.8–7.8; p < 0.001) and the 8th grade level by an average of 5.3 grade levels (95% CI, 4.8–5.8; p < 0.001). The mean Flesch Reading Ease Score was 39/100 (‘difficult’).

Conclusion

Currently available online PEMs related to radiation safety are still written at higher than recommended reading levels. Radiation safety is a topic in which the specialist training of radiologists is crucial in providing guidance to patients. Addressing the readability of online PEMs can improve radiology-patient communication and support the shift to a patient-centred model of practice.

Readability of Patient Educational Materials in Pediatric Orthopaedics

BACKGROUND

Parents are increasingly turning to the internet to seek pediatric health information. Numerous organizations advise that patient educational materials (PEMs) should not surpass the sixth-grade reading level. We aimed to assess the readability of online pediatric orthopaedic PEMs.

METHODS

The readability of 176 articles pertaining to pediatric orthopaedics from the American Academy of Orthopaedic Surgeons (AAOS), Pediatric Orthopaedic Society of North America (POSNA), and American Academy of Pediatrics (AAP) websites was assessed with the use of 8 readability formulae: the Flesch-Kincaid Reading Grade Level, the Flesch Reading Ease Score, the Raygor Estimate, the SMOG, the Coleman-Liau, the Fry, the FORCAST, and the Gunning Fog. The mean reading grade level (RGL) of each article was compared with the sixth and eighth-grade reading levels. The mean RGL of each website's articles also was compared.

RESULTS

The cumulative mean RGL was 10.2 (range, 6.6 to 16.0). No articles (0%) were written at the sixth-grade reading level, and only 7 articles (4.0%) were written at or below the eighth-grade reading level. The mean RGL was significantly higher than the sixth-grade (95% confidence interval [CI] for the difference, 4.0 to 4.4; p < 0.001) and eighth-grade (95% CI, 2.0 to 2.4; p < 0.001) reading levels. The mean RGL of articles on the POSNA website was significantly lower than the mean RGL of the articles on the AAOS (95% CI, -1.8 to -1.0; p < 0.001) and AAP (95% CI, -2.9 to -1.1; p < 0.001) websites.

CONCLUSIONS

Pediatric orthopaedic PEMs that are produced by the AAOS, the POSNA, and the AAP have readability scores that exceed recommendations. Given the increasing preference of parents and adolescents for online health information, the growing body of online PEMs, and the critical role that health literacy plays in patient outcomes, substantial work is required to address the readability of these materials.

Readability of Patient Educational Materials in Hip and Knee Arthroplasty: Has a Decade Made a Difference?

BACKGROUND

The Internet has become an increasingly popular resource among orthopedic patients for health education. Numerous organisations recommend that patient educational materials (PEMs) should not exceed the 6^th grade reading level. Despite this, studies have repeatedly shown the reading grade level (RGL) of PEMs to be too advanced across a range of surgical specialties. We aimed to determine the readability of online hip and knee arthroplasty PEMs.

METHODS

The readability of 134 articles pertaining to hip and knee arthroplasty from 5leading worldwide healthcare websites were assessed, using 8 readability formulae; the Flesch-Kincaid Reading Grade Level, the Flesch Reading Ease Score, Raygor Estimate, SMOG, Coleman-Liau, Fry, FORCAST and Gunning Fog. The mean RGL was compared to the 6^th and 8^thgrade reading level. The mean RGL of each website was also compared.

RESULTS

The mean cumulative RGL was 12 (range = 7-16.1). No articles (0%) were written at a 6^th grade reading level and only 4 articles (3%) were written at or below the 8^th grade reading level. The mean RGL was significantly higher than the 6^th (95% CI, 5.62-6.30; P < .0001) and 8^th grade reading level (95% CI, 3.63-4.30; P < .0001). There was a significant difference between the RGLs of the 5websites (P = .001).

CONCLUSION

Arthroplasty PEMs produced by leading worldwide healthcare organisations have readability scores that are above the recommended levels. Given the imperative role of health literacy in patient outcomes and satisfaction, and the increasing prevalence of Internet use among orthopedic patients, a substantial amount of work needs to be done to improve the readability of these materials.

Auto-Decompression - Preserved Neurological Function in Bilateral Cervical Facet Dislocations

Introduction Bilateral cervical facet dislocation (BCFD) is an uncommon injury with a high incidence of severe neurological impairment. We describe 4 cases of BCFD with preserved neurological function. Cases Case 1: A 78-year-old female who suffered two ground level falls (GLFs). Pre-operative American Spinal Injury Association (ASIA) Score was C5D. Imaging revealed a BCFD at C6/C7 and a C6 laminar fracture. Case 2: A 63-year-old male suffered a fall down 14 steps. Pre-operative ASIA score was E. Imaging demonstrated a BCFD at C7/T1, and a C6 laminar fracture. Case 3: A 46-year-old male collided with a tree while descending a hill on a bicycle. Pre-operative ASIA score was C6D. Imaging revealed a BCFD at C7/T1 and a C7 laminar fracture. Case 4: A 67-year-old male suffered a GLF while exiting a stationary car. Pre-operative ASIA score on admission was E. Imaging revealed a BCFD at C6/C7 with bilateral laminar fractures at C5 and C6. Outcome All cases underwent 2-stage surgical fixation. All cases maintained or had an improved ASIA score post-operatively. Conclusion In all cases, the presence of concurrent laminar fractures resulted in an auto-decompression of the spinal canal, preserving neurological function.

Timing of surgical fixation in traumatic spinal fractures: A systematic review

BACKGROUND

The optimal timing of fracture fixation following spinal injury is controversial. Many spinal fractures occur as part of polytrauma requiring a complex management strategy. Whilst the decision to stabilize unstable spinal column injuries is without debate, the duration between injury and definitive fixation can impact on the incidence of post-operative complications. This study was designed to systemically summarize and compare the complication profile of early vs late stabilization of spinal injuries, in an attempt to unveil an appropriate treatment protocol for traumatic spinal fractures.

METHODS

A comprehensive search strategy was performed on the PubMed, Cochrane, and Google Scholar databases using key words. The search strategy provided 1120 results. Forty-six articles were reviewed for full-text. Reference lists were analysed for potential additional texts.

RESULTS

Sixteen articles met the inclusion criteria and were included for systematic review. Studies were controversial and the overall result was inconclusive. Several studies favour early stabilisation to reduce post-surgical complication rates, especially in cases of patients with high Injury Severity Scale (ISS) scores. However, this is challenged by a small number of studies reporting a higher mortality rate in the early-stabilisation cohort.

CONCLUSION

Due to limited studies and a small overall cohort, the authors would cautiously recommend the early surgical fixation of unstable spine fractures in the stable trauma patient. For severely injured patients, the discordance among literature warrants the need for further investigation.
