RESUMO
OBJECTIVE: To determine if children who present with an elbow flexion contracture (EFC) from brachial plexus birth injury (BPBI) are more likely to develop shoulder contracture and undergo surgical treatment. STUDY DESIGN: Retrospective review of children <2 years of age with BPBI who presented to a single children's hospital from 1993 to 2020. Age, elbow and shoulder range of motion (ROM), imaging measurements, and surgical treatment and outcome were analyzed. Patients with an EFC of ≥10° were included in the study sample. Data from 2445 clinical evaluations (1190 patients) were assessed. The final study cohort included 72 EFC cases matched with 230 non-EFC controls. Three patients lacked sufficient follow-up data. RESULTS: There were 299 included patients who showed no differences between study and control groups with respect to age, sex, race, ethnicity, or functional score. Patients with EFC had 12° less shoulder range of motion (95% CI, 5°-20°; P < .001) and had 2.5 times the odds of shoulder contracture (OR, 2.5; 95% CI, 1.3-4.7; P = .006). For each additional 5° of EFC, the odds of shoulder contracture increased by 50% (OR, 1.5; 95% CI, 1.2-1.8; P < .001) and odds of shoulder procedure increased by 62% (OR, 1.62; 95% CI, 1.04-2.53; P = .03). Sensitivity of EFC for predicting shoulder contracture was 49% and specificity was 82%. CONCLUSIONS: In patients with BPBI <2 years of age, presence of EFC can be used as a screening tool in identifying shoulder contractures that may otherwise be difficult to assess. Prompt referral should be arranged for evaluation at a BPBI specialty clinic, because delayed presentation risks worsening shoulder contracture and potentially more complicated surgery.

BACKGROUND: Orthopaedic surgeons are exposed to high levels of radiation, which may lead to higher rates of cancer among orthopaedic surgeons. There are a series of techniques currently practiced to pin supracondylar humerus fractures including pinning the arm on the C-arm itself, using a plexiglass rectangle or a graphite floating arm board; however, the variation in radiation exposure to the surgeon is unknown. We aimed to determine how the position of the C-arm affects radiation exposure to the surgeon during the treatment of a pediatric supracondylar humerus fracture. MATERIAL AND METHODS: A simulated operating room was created to simulate a closed reduction and percutaneous pinning of a supracondylar humerus fracture. A phantom model was used to simulate the patient's arm. We assessed performing the procedure with the arm on plexiglass, graphite, or on top of the C-arm image receptor. The C-arm was positioned either with the source down and image receptor up (standard position) or with the source up and image receptor down (inverted position). Radiation exposure was recorded from levels corresponding to the surgeon's head, midline, and groin. The estimated effective dose equivalent was calculated to account for the varying radiation sensitivity of different organs. RESULTS: We found the effective dose equivalent, or the overall body damage from radiation, was 5.4 to 7.8% higher than the surgeon when the C-arm was in the inverted position (source up, image receptor down). We did not find any differences in radiation exposure to the surgeon when the arm was supported on plexiglass versus graphite. CONCLUSION: The C-arm positioned in the standard fashion exposes the surgeon to less damaging radiation. Therefore, when the surgeon is standing, we recommend using the C-arm in the standard position. CLINICAL RELEVANCE: Orthopaedic surgeons who stand should use the C-arm in the standard position to pin supracondylar humerus fractures to lower the risk of ionizing radiation exposure.

BACKGROUND: To meet the complex needs of healthcare delivery, the Ministry of Health and Long Term Care (MOHLTC) introduced Physician Assistants (PAs) into the Ontario health care system in 2006 with the goal of helping to increase access to care, decrease wait times, improve continuity of care and provide a flexible addition to the healthcare workforce. The characterization of healthcare organizations as complex adaptive systems (CAS) may offer insight into the relationships and interactions that optimize and restrict successful PA integration. The aim of this study is to explore the integration of PAs across multiple case settings and to understand the role of PAs within complex adaptive systems. METHODS: An exploratory, multiple-case study was used to examine PA role integration in four settings: family medicine, emergency medicine, general surgery, and inpatient medicine. Interviews were conducted with 46 healthcare providers and administrators across 13 hospitals and 6 family medicine clinics in Ontario, Canada. Analysis was conducted in three phases including an inductive thematic analysis within each of the four cases, a cross-case thematic analysis, and a broader, deductive exploration of cross-case patterns pertaining to specific complexity theory principles of interest. RESULTS: Forty-six health care providers were interviewed across 19 different healthcare sites. Support for PA contributions across various health care settings, the importance of role awareness, supervisory relationship attributes, and role vulnerability are interconnected and dynamic. Findings represent the experiences of PAs and other healthcare providers, and demonstrate how the PAs willingness to work and ability to build relationships allows for the establishment of interprofessional, collaborative, and person-centered care. As a self-organizing agent in complex adaptive systems (i.e., health organizations), PA role exploration revealed patterns of team behavior, non-linear interconnections, open relationships, dynamic systems, and the legacy of role implementation as defined by complexity theory. CONCLUSIONS: By exploring the role of PAs across multiple sites, the complexity theory lens concurrently fosters an awareness of emerging patterns, relationships and non-linear interactions within the defined context of the Ontario healthcare system. By establishing collaborative, interprofessional care models in hospital and community settings, PAs are making a significant contribution to Ontario healthcare settings.

BACKGROUND: Recent adult literature has demonstrated that in the setting of acute compartment syndrome (ACS), if fasciotomy wounds are not closed after the first debridement, they are unlikely to be closed via delayed primary closure (DPC). The purpose of this study was to report the success of DPC through serial debridement in children with fasciotomy wounds secondary to ACS and to determine whether length of hospital stay is negatively affected by adopting a DPC strategy. METHODS: We identified all patients treated with fasciotomy for ACS (aged 0 to18 y). Patient, injury, and treatment characteristics were summarized by fasciotomy treatment type. Patients were grouped as: primary closure, DPC, and flap or skin graft (F/SG). For patients who required additional debridements after initial fasciotomy, treatment success was defined as closure by DPC (without requiring F/SG). Multivariable logistic regression was used to determine factors associated with additional surgeries, complications, and treatment success. RESULTS: A total of 82 children underwent fasciotomies for ACS. Fifteen (18%) patients were treated with primary closure at the time of their initial fasciotomy and were excluded from the remainder of the analysis, 48 (59%) patients underwent DPC, and 19 (23%) patients were treated with F/SG. The majority of delayed fasciotomy wounds were successfully closed by DPC (48/67, 72%) and the rate of successful closure remained consistent with each successive operative debridement. There were no differences across DPC and F/SG groups with respect to age, method of injury, or injury severity. Patients who underwent F/SG remained in the hospital for an average of 12 days compared with 8 days for those who underwent DPC (P<0.001). CONCLUSIONS: In the setting of ACS, pediatric fasciotomy wounds that are not closed after the first postfasciotomy debridement still have a high likelihood of being closed through DPC with serial surgical debridement. In children, persisting with DPC strategy for fasciotomy closure after ACS is more successful than it is in adults. LEVEL OF EVIDENCE: Level III.

BACKGROUND: Surgical treatment is recommended for patients with unstable osteochondritis dissecans (OCD) of the elbow. However, little information is available comparing the anticipated results from the host of techniques. In this investigation, clinical and radiographic resolution as well as return to sports rates were assessed in adolescent patients following loose body (LB) removal and drilling/microfracture of grade IV lesions. METHODS: We reviewed 21 adolescents treated with LB removal and drilling/microfracture for grade IV elbow OCD. Patients with additional elbow pathology, prior elbow surgery, or <1 year follow-up were excluded. Clinical resolution was defined as resolution of tenderness and radiographic resolution as resolution of edema on magnetic resonance imaging (MRI). Return to sport rates and Timmerman scores were assessed. Mean clinical and MRI follow-up times were 2.2±1.19 and 2.4±1.54 years, respectively. Clinical and radiographic parameters associated with clinical and/or radiographic resolution or return to sports were determined using penalized likelihood logistic regression. Wilcoxon signed-rank tests were used to evaluate the change in range of motion and in Timmerman scores. RESULTS: Fifteen (71.4%) patients had either clinical or radiographic resolution at most recent follow-up. Nine (50%) had complete resolution on MRI, whereas 13 (61.9%) were nontender at their follow-up. Four patients with recurrent LBs underwent revision surgery. There were no complications in the 21 index procedures. Eighteen (85.7%) patients returned to any sport, whereas 14 (66. 7%) returned to their primary sport. Elbow flexion and extension improved by medians of 12 and 21 degrees, respectively (P=0.002, 0.01). Timmerman scores improved by a median of 30 (P=0.001). Shorter duration of symptoms correlated with smaller OCD lesions (P=0.03) and with improved clinical or radiographic resolution and return to sport rates. CONCLUSIONS: The majority of patients with grade IV elbow OCD achieves clinical and/or radiographic resolution and return to sports 2 years after LB removal and drilling/microfracture. Recurrence may be seen, however, and further investigation is needed to assess the efficacy of this technique compared with other treatment strategies. LEVEL OF EVIDENCE: Level IV.

BACKGROUND: When stable osteochondritis dissecans (OCD) lesions of the femoral condyle in a skeletally immature patient fail to heal with nonoperative methods, the standard of care treatment is condylar OCD drilling. Two primary OCD drilling techniques have been described, but no prospective studies have compared their relative effectiveness. PURPOSE/HYPOTHESIS: The purpose of this study was to compare the healing and function after transarticular drilling (TAD) with that after retroarticular drilling (RAD). It was hypothesized that there would be no difference in rate or time to healing, rate or time to return to sports, patient-reported outcomes (PROs), or secondary OCD-related surgery. STUDY DESIGN: Randomized controlled clinical trial; Level of evidence, 1. METHODS: Skeletally immature patients with magnetic resonance imaging-confirmed stable OCD lesions of the medial femoral condyle who did not demonstrate substantial healing after a minimum of 3 months of nonoperative treatment were prospectively enrolled by 1 of 17 surgeon-investigators at 1 of 14 centers. Patients were randomized to the TAD or RAD group. Tourniquet time, fluoroscopy time, and complications were compared between the treatment groups. Postoperatively, serial radiographs were obtained every 6 weeks to assess healing, and PROs were obtained at 6 months, 12 months, and 24 months. RESULTS: A total of 91 patients were included, consisting of 51 patients in the TAD and 40 patients in the RAD group, who were similar in age, sex distribution, and 2-year PRO response rate. Tourniquet time and fluoroscopy time were significantly shorter with TAD (mean, 38.1 minutes and 0.85 minutes, respectively) than RAD (mean, 48.2 minutes and 1.34 minutes respectively) (P = .02; P = .004). In the RAD group, chondral injury from K-wire passage into the intra-articular space was reported in 9 of 40 (22%) patients, but no associated postoperative clinical sequelae were identified in these patients. No significant differences between groups were detected in follow-up Pediatric-International Knee Documentation Committee, Lysholm, Marx Activity Scale, or Knee injury and Osteoarthritis Outcome Score Quality of Life scores. Healing parameters were superior at 6 months and 12 months in the TAD group, compared with the RAD group, and secondary OCD surgery occurred in 4% of patients who underwent TAD and 10% of patients who underwent RAD (P = .40). Patients in the TAD group returned to sports earlier than those in the RAD group (P = .049). CONCLUSION: TAD showed shorter operative time and fluoroscopy time and superior healing parameters at 6 and 12 months, but no differences were seen in 24-month healing parameters or PROs at all follow-up time points, when compared with RAD. REGISTRATION: NCT01754298 (ClinicalTrials.gov identifier).

PURPOSE: Clinical competence is essential for providing safe, competent care and is regularly assessed to ensure health care practitioners maintain competence. When deficiencies in competence are identified, practitioners may undergo remediation. However, there is limited evidence regarding the effectiveness of remediation programs. The purpose of this review is to examine the purpose, format, and outcomes of remediation programs for regulated health care practitioners. METHODS: All six stages of the scoping review process as recommended by Levac et al were undertaken. A search was conducted within MEDLINE, Embase, CINAHL, ERIC, gray literature databases, and websites of Canadian provincial regulatory bodies. Emails were sent to Registrars of Canadian regulatory bodies to supplement data gathered from their websites. RESULTS: A total of 14 programs were identified, primarily for physicians (n = 8). Reasons for remediation varied widely, with some programs identifying multiple reasons for referral such as deficiencies in recordkeeping (n = 7) and clinical skills (n = 6). Most programs (n = 9) were individualized to address specific deficiencies in competence. The process of remediation followed three stages: (1) assessment, (2) active remediation, and (3) reassessment. Most programs (n = 12) reported that remediation was effective in improving competence. CONCLUSIONS: Regulatory bodies should consider implementing individualized remediation programs to ensure that clinicians' deficiencies in competence are addressed effectively. Further research is indicated, using reliable and valid outcome measures to assess competence immediately after remediation programs and beyond.

OBJECTIVES: To identify recommendations for determining patient panel/caseload size for nurse practitioners in community-based primary health care settings. DESIGN: Scoping review of the international published and grey literature. DATA SOURCES: The search included electronic databases, international professional and governmental websites, contact with experts, and hand searches of reference lists. Eligible papers had to (a) address caseload or patient panels for nurse practitioners in community-based primary health care settings serving an all-ages population; and (b) be published in English or French between January 2000 and July 2014. Level one testing included title and abstract screening by two team members. Relevant papers were retained for full text review in level two testing, and reviewed by two team members. A third reviewer acted as a tiebreaker. Data were extracted using a structured extraction form by one team member and verified by a second member. Descriptive statistics were estimated. Content analysis was used for qualitative data. RESULTS: We identified 111 peer-reviewed articles and grey literature documents. Most of the papers were published in Canada and the United States after 2010. Current methods to determine panel/caseload size use large administrative databases, provider work hours and the average number of patient visits. Most of the papers addressing the topic of patient panel/caseload size in community-based primary health care were descriptive. The average number of patients seen by nurse practitioners per day varied considerably within and between countries; an average of 9-15 patients per day was common. Patient characteristics (e.g., age, gender) and health conditions (e.g., multiple chronic conditions) appear to influence patient panel/caseload size. Very few studies used validated tools to classify patient acuity levels or disease burden scores. DISCUSSION: The measurement of productivity and the determination of panel/caseload size is complex. Current metrics may not capture activities relevant to community-based primary health care nurse practitioners. Tools to measure all the components of these role are needed when determining panel/caseload size. Outcomes research is absent in the determination of panel/caseload size. CONCLUSION: There are few systems in place to track and measure community-based primary health care nurse practitioner activities. The development of such mechanisms is an important next step to assess community-based primary health care nurse practitioner productivity and determine patient panel/caseload size. Decisions about panel/caseload size must take into account the effects of nurse practitioner activities on outcomes of care.

An occupational therapy program and an agency that addresses the needs of community elderly collaborated to resolve a problem of the homebound people who receive Meals-on-Wheels. Staff of the agency realized that many elders were unable to safely and comfortably reheat their delivered meals. Risk factors of malnutrition, bacterial infection, functional decline and reduced quality of life are the sequelae. To solve this complex problem, an interdisciplinary team formed to clarify the nature of the problem and implement a plan of action. The result is "The Microwave Project," designed to enhance nutrition and function of elderly people who are homebound.
