Secondary Bony Defects after Soft Tissue Reconstruction in Limb-Threatening Lower Extremity Injuries: Does the Approach to Flap Elevation Matter?

BACKGROUND: Limb-threatening lower extremity injuries often require secondary bone grafting after soft tissue reconstruction. We hypothesized that there would be fewer wound complications when performing secondary bone grafting via a remote surgical approach rather than direct flap elevation. METHODS: A retrospective cohort study was performed at a single Level 1 trauma center comparing complications after secondary bone grafting in patients who had undergone previous soft tissue reconstruction after open tibia fractures between 2006 and 2020. Comparing bone grafting via a remote surgical incision versus direct flap elevation, we evaluated wound dehiscence requiring return to the operating room as the primary outcome. Secondary outcomes were deep infection and delayed amputation. RESULTS: We identified 129 patients (mean age: 40 years, 82% male) with 159 secondary bone grafting procedures. Secondary bone grafting was performed via a remote surgical approach in 54% (n = 86) and direct flap elevation in 46% (n = 73) of cases. Wound dehiscence requiring return to the operating room occurred in one patient in the flap elevation group (1%) and none of the patients in the remote surgical approach. The odds of deep wound infection (OR, 1.77; p = 0.31) or amputation (OR, 1.43; p = 0.73) did not significantly differ between surgical approaches. No significant differences were found in complications between the reconstructive surgeon elevating and re-insetting the flap and the orthopaedic trauma surgeon performing the flap elevation and re-inset. CONCLUSION: Direct flap elevation for secondary bone grafting after soft tissue reconstruction for open tibia fractures did not result in more complications than bone grafting via a remote surgical approach. These findings should reassure surgeons to allow other clinical factors to influence the surgical approach for bone grafting.

Increased actual sling wear is associated with better early patient-reported and image-based outcomes after shoulder surgery.

BACKGROUND: Prior studies have failed to show differences in functional outcomes for patient-reported sling use after rotator cuff repair. Temperature-sensing devices are used to more accurately measure brace adherence. The purposes of this study were to quantify actual sling adherence and its predictors and to establish whether increased sling adherence is associated with improved functional and image-based outcomes. METHODS: We performed a prospective cohort study of 65 patients undergoing shoulder surgery requiring ≥4 weeks of postoperative sling use. Temperature-sensing devices were implanted in the slings to monitor sling adherence. Patient-reported sling adherence was determined from a questionnaire. Patients were considered 80% adherent if they wore the sling 16 h/d (112 h/week) when 20 h/d was prescribed. The primary outcomes were patient-reported and actual sling adherence, patient-reported outcomes (American Shoulder and Elbow Surgeons score and visual analog scale pain score) within 12 months postoperatively, and image-based failure based on ultrasound or radiography at 6 weeks and 1 year postoperatively. RESULTS: Patient-reported sling adherence was highly sensitive (82.8%), was poorly specific (28.6%), had low accuracy (53.1%), and was weakly correlated with actual sling adherence (r = 0.32, P = .009). On multivariable logistic regression analysis, male patients were 91% less likely than female patients to be adherent with sling use (odds ratio, 0.09; 95% confidence interval [CI], 0.02-0.42; P = .002). Additionally, obese and morbidly obese patients were 88% (95% CI, 0.02-0.84; P = .033) and 98% (95% CI, 0.002-0.27; P = .003), respectively, less likely than non-obese patients to adhere to sling wear postoperatively. After we controlled for surgical procedure, visual analog scale pain scores were significantly better at 6 weeks (ß = -1.47; 95% CI, -2.88 to -0.05; P = .04) and 3 months (ß = -1.68; 95% CI, -3.28 to -0.08; P = .04) if patients adhered to sling wear. A receiver operating characteristic curve showed that 13.6 hours and 15.4 hours of daily sling wear optimized image-based outcomes at 6 weeks (failure rate, 0% vs. 16%; P = .01) and 1 year (failure rate, 3% vs. 28%; P = .008) postoperatively, respectively. CONCLUSION: The results of this study demonstrate that patient-reported sling adherence is unreliable, adherence can be predicted by female sex and lower body mass index, and increased sling adherence is associated with improved early pain scores and image-based outcomes. These data can help inform future studies using postoperative sling protocols as patient-reported sling adherence is not an accurate method to assess sling use.

The Effect of Patients' Understanding of Sling Necessity and Home Assistance on Sling Wear After Shoulder Surgery.

BACKGROUND: Perioperative education and socioeconomic factors influence patient behavior. Recent evidence has suggested that sling compliance is associated with improved outcomes after shoulder surgery; it is important to investigate factors that influence sling compliance. PURPOSE: To determine the associations between postoperative sling wear and patients' understanding of sling necessity, postoperative home assistance, and social deprivation. STUDY DESIGN: Cohort study; Level of evidence, 2. METHODS: A total of 66 patients were prospectively enrolled from 2018 to 2020 if they were ≥18 years of age and undergoing shoulder surgery requiring a sling for at least 1 month postoperatively. Sling wear was measured using a temperature-sensing device. At 6 weeks postoperatively, patients' understanding for sling necessity was determined by their response to a question on the Medical Adherence Measure questionnaire, "Why did you have to wear a shoulder sling?" The Patient Understanding Grading Scale (PUGS) was developed to quantify patient responses. PUGS was graded 1 to 3, with grade 1 corresponding to the least technical knowledge. Patient characteristics, social deprivation (Area Deprivation Index [ADI]), and home assistance were additionally analyzed. RESULTS: There were no significant differences in baseline characteristics between patients when stratified by PUGS grade. Multivariable linear regression analysis for total hours of sling wear per week showed that patients with PUGS grade 2 (ß, 48.2 hours; P = .007) and grade 3 (ß, 59.5 hours; P = .003) wore their slings significantly more than grade 1 patients. Patients with home assistance had significantly greater day hours (73.5 ± 33.0 vs 44.0 ± 24.5 hours; P = .037) of sling wear per week, but there was no difference in night sling hours. Patients older than 60 years wore their slings significantly more, while men and those with a higher body mass index (BMI) wore their slings significantly less. ADI was not significantly associated with sling wear. CONCLUSION: This study demonstrates that patients with greater understanding for sling necessity, those with home assistance, and patients >60 years have greater sling wear, while male patients and those with a higher BMI have lower sling compliance. ADI was not a significant contributor.

Are Pelvic Binders an Effective Prehospital Intervention?

OBJECTIVE: Widespread adoption of prehospital pelvic circumferential compression devices (PCCDs) by emergency medical services (EMS) systems has been slow and variable across the United States. We sought to determine the frequency of prehospital PCCD use by EMS providers. Secondarily, we hypothesized that prehospital PCCD use would improve early hemorrhagic shock outcomes. METHODS: We conducted a single-center retrospective cohort study of 162 unstable pelvic ring injuries transported directly to our center by EMS from 2011 to 2020. Included patients received a PCCD during their resuscitation (prehospital or emergency department). Prehospital treatment details were obtained from the EMS medical record. The primary outcome was the proportion of patients who received a PCCD by EMS before hospital arrival. Secondarily, we explored factors associated with receiving a prehospital PCCD, and its association with changes in vital signs, blood transfusion, and mortality. RESULTS: EMS providers documented suspicion of a pelvic ring fracture in 85 (52.8%) patients and 52 patients in the cohort (32.2%) received a prehospital PCCD. Wide variation in prehospital PCCD use was observed based on patient characteristics, geographic location, and EMS provider level. Helicopter flight paramedics applied a prehospital PCCD in 46% of the patients they transported (38/83); in contrast, the EMS organizations geographically closest to our hospital applied a PCCD in ≤5% of cases (2/47). Other predictors associated with receiving a prehospital PCCD included lower body mass index (p = 0.005), longer prehospital duration (p = 0.001) and lower Injury Severity Score (p < 0.05). We were unable to identify any improvements in clinical outcomes associated with prehospital PCCD, including early vital signs, number of blood transfusions within 24 hours, or mortality during admission (p > 0.05). CONCLUSION: Our results demonstrate wide practice variation in the application of prehospital PCCDs. Although disparate PCCD application across the state is likely explained by differences across EMS organizations and provider levels, our study was unable to identify any clinical benefits to the prehospital use of PCCDs. It is possible that the benefits of a prehospital PCCD can only be observed in the most displaced fracture patterns with the greatest early hemodynamic instability.

Reliability, validity, and responsiveness of a novel subscapularis outcome score: the Baltimore Orthopedic Subscapularis Score.

Background: Available surveys that evaluate shoulder strength and pain often combine rotator cuff muscles making the test unable to differentiate subscapularis tears from other pathology including concomitant supraspinatus, infraspinatus tears. The purpose of this study was to validate a subscapularis-specific shoulder survey (Baltimore Orthopedic Subscapularis Score) as a viable clinical outcome assessment through analysis of psychometric properties. Methods: A 5-question survey was given to a study population of 390 patients, 136 of whom had full thickness rotator cuff tears with a minimum score of 5 (better) and a maximum score of 25 (worse). Surveys were given during the initial consultation, preoperative visit, and postoperative visit. Content validity, construct validity, test-retest reliability, responsiveness to change, internal consistency, and minimal clinically important difference using distribution and anchor-based methods were determined for our subscapularis function survey. Results: A high correlation was reported on test-retest reliability (intraclass correlation coefficient = 0.89). An acceptable internal consistency was reported for all patients surveyed (Cronbach alpha = 0.91). Floor and ceiling effects for patients with rotator cuff pathology were minimized (1% for both). Patients with an isolated subscapularis tear scored worse than supraspinatus/infraspinatus tears and exhibited similar dysfunction as patients with a supraspinatus/infraspinatus/subscapularis tear. An acceptable construct validity was reported with subscapularis-involved tears demonstrating higher scores with significance (P < .05). There was excellent responsiveness to change with a standardized response mean of 1.51 and effect size of 1.27 (large > 0.8). The minimal clinically important difference using a distribution and anchor-based method was 4.1 and 4.6, respectively. Among patients with rotator cuff tears in this population, a score of 22 or higher predicts a subscapularis tear 75% of the time, in spite of its low overall prevalence. Conclusion: The subscapularis shoulder score demonstrated acceptable psychometric performance for outcomes assessment in patients with rotator cuff disease. This survey can be used as an effective clinical tool to assess subscapularis function.

Association of Radial Head Fracture Treatment With Long-Term Function.

BACKGROUND: Radial head fractures are often associated with poor outcomes. Both open reduction and internal fixation (ORIF) and radial head arthroplasty (RHA) might be considered in operative cases. This study aimed to compare long-term patient-reported functional outcomes among patients with operatively treated radial head fractures. METHODS: A cross sectional study conducted at a Level I trauma center was used to identify patients with a radial head fracture who underwent ORIF or RHA between 2006 and 2018, and agreed to complete a survey in 2020. The primary outcome measure was the Quick Disabilities of the Arm, Shoulder, and Hand (QuickDASH) score. RESULTS: Seventy-six patients participated in the study. No significant differences in outcomes were observed between groups. QuickDASH scores were similar for both groups (ORIF: mean = 15.7, SD = 18.4; RHA: mean = 22.8, SD = 18.6; mean difference = 0.2 [-9.0 to 9.3], P = .97). Nineteen (37%) ORIF patients and 12 (48%) RHA patients reported a need for pain medication (adjusted odds ratio [OR] = 0.8 [0.3-2.4], P = .70). Thirteen (25%) ORIF patients and 6 (24%) RHA patients required additional surgery (adjusted OR = 1.7 [0.5-6.2], P = .39). A subgroup analysis of multi-fragmentary fractures revealed similar findings. CONCLUSION: Patient-reported outcomes, which included a subgroup analysis of multi-fragmentary fractures, were similar between ORIF and RHA groups at an average of 7.5 years from surgery. Reconstructing the radial head might not result in worse outcomes than RHA when both options are employed according to the best judgment of the operating surgeon.

Surgical factors associated with symptomatic implant removal after patella fracture.

OBJECTIVES: To determine whether certain types of fixation and other factors associated with the fixation could be identified that predict an increased risk of symptomatic implant removal. METHODS: We conducted a retrospective cohort study at our urban academic level 1 trauma center. Patients aged ≥18 years who underwent operative fixation for patella fracture were included. The primary outcome was symptomatic implant removal after operative fixation. RESULTS: Of the 186 study patients (mean age, 44 [SD 17] years, 65% male), 53 patients (28.5%) underwent symptomatic implant removal. Modifiable risk factors for symptomatic implant removal included the use of Kirschner (k)-wires (OR: 4.93; 95% CI, 1.89-14.10; p < 0.001), and a trend towards significance for implant prominence >5 mm (OR: 2.57; 95% CI, 0.93-7.93; p = 0.07). Symptomatic implant removal was also less likely in patients >45 years of age (OR: 0.14; 95% CI, 0.06-0.34; p < 0.01), of a racial minority (OR: 0.40; 95% CI, 0.17-0.88; p = 0.03), and a body mass index >25 kg/m2 (OR: 0.39; 95% CI, 0.18-0.84; p = 0.02). The final model demonstrated excellent prognostic performance, with an AUC of 0.83 (0.76-0.90). CONCLUSION: We identified both modifiable and non-modifiable factors associated with symptomatic implant removal in patients with patella fractures. Surgeons should be aware that the use of k-wires and any implant prominence exceeding 5 mm might be associated with increased odds of symptomatic implant removal in patients with patella fractures.

Is a Low-Cost Drill Cover System Noninferior to Conventional Surgical Drills for Skeletal Traction Pin Placement?

SUMMARY: The Drill Cover system was developed as a low-cost alternative to conventional surgical drills with specific applicability to low- and middle-income countries. However, the system may also be useful for the sterile placement of traction pins in the emergency department of high-income country hospitals. In September 2019, a US-based Level-1 trauma center began using the Drill Cover system to apply skeletal traction pins in patients with femoral shaft fractures. With these data, we performed a retrospective interrupted time series study to determine if the Drill Cover system was noninferior to conventional surgical drills in terms of infections at the traction pin site. The study included 205 adult patients with femoral shaft fractures initially placed in skeletal traction using a conventional surgical drill (n = 150, preintervention group) or the Drill Cover system (n = 55, postintervention group). The primary outcome was an infection at the site of skeletal traction pin placement that required surgery or antibiotics, which was compared between groups using a noninferiority test with a 1-sided alpha of 0.05 and a noninferiority margin of 3%. No infections at the site of skeletal traction pin placement were found in either the preintervention or the postintervention group (difference, 0%; 95% confidence interval: 0.0%-1.4%; noninferiority P value < 0.01). The results suggest that the Drill Cover system was noninferior to conventional surgical drills regarding infections at the site of skeletal traction pins. The Drill Cover system may be a safe alternative to the more expensive surgical drills for skeletal traction pin placement in the emergency room environment.

Risk factors associated with atraumatic posterolateral rotatory instability.

BACKGROUND: Traumatic posterolateral rotatory instability after elbow dislocation or fracture dislocation has been well described. However, few reports cover atraumatic posterolateral rotatory instability as a cause of lateral-sided elbow pain. We assessed the risk factors and epidemiology of atraumatic posterolateral rotatory instability in a case-control study. METHODS: A retrospective review of all patients treated operatively for atraumatic posterolateral rotatory instability during a 6-year period was compared with a group of patients with extensor carpi radialis brevis tendinopathy without instability treated during the same time period. Bivariate and multiple logistic regression statistical analyses were used to investigate the following risk factors: gender, age, hand dominance, diabetes, smoking, body mass index, corticosteroid injection history, and duration of symptoms. Disabilities of the Arm, Shoulder, and Hand and pain scores were obtained preoperatively and postoperatively. RESULTS: Thirteen patients with atraumatic posterolateral rotatory instability were compared with 12 patients with extensor carpi radialis brevis tendinopathy. Multivariate analysis revealed patients with atraumatic posterolateral rotatory instability were more likely to have multiple corticosteroid injections (P = .05) and present with a longer duration of symptoms (P = .03). Postoperative pain scores improved in both groups. CONCLUSIONS: Atraumatic posterolateral rotatory instability should be considered in the differential diagnosis of lateral elbow when patients present with a protracted clinical course. Statistically, posterolateral rotatory instability patients more often present with a history of multiple corticosteroid injections.

An accurate method of measuring shoulder sling compliance: a validation study.

BACKGROUND: The effect of postoperative shoulder sling compliance on surgical outcomes is unknown. The goal was to determine an accurate method to measure sling compliance. We compared volunteer recorded sling wear time with temperature-based sensors to monitor sling compliance. METHODS: Data loggers sutured at three locations measured heat generated in 15-minute intervals. Slings wearers logged sling wear to accurately cross-reference with temperature sensors. Secondary experiments analyzed whether surrounding ambient temperature can be discerned from actual sling wear. We created an algorithm to describe actual sling wear time as a function of heat recorded and calculated percent wear accuracy. RESULTS: The modified sling was worn for 172 h. The algorithm modeled sling on/off times by analyzing cutoff temperatures. Diagnostic accuracy was >99 % for the three locations, with no statistically significant differences among them. Compared with sling wear, ambient temperature took longer to reach critical temperature values determined by the algorithm, helping distinguish compliance from false positives. CONCLUSIONS: The described algorithm can effectively quantify shoulder sling wear time based on heat-generated sensor readings. False positives from ambient temperature are minimal. This measurement method could be used to study the relationship between postoperative sling use and functional outcomes after shoulder surgery.

A Prospective Clinical Trial Comparing Surgical Fixation Versus Nonoperative Management of Minimally Displaced Complete Lateral Compression Pelvis Fractures.

OBJECTIVE: To compare the early pain and functional outcomes of operative fixation versus nonoperative management for minimally displaced complete lateral compression (LC; OTA/AO 61-B1/B2) pelvic fractures. DESIGN: Prospective clinical trial. SETTING: Two academic trauma centers. PATIENTS: Forty-eight adult patients with LC pelvic ring injuries with <10 mm of displacement were treated nonoperatively and 47 with surgical fixation. Sixty percent of participants were randomized. Seventy-three percent of the fractures were displaced <5 mm, and 71% were LC-1 patterns. INTERVENTION: Operative fixation versus nonoperative management. MAIN OUTCOME MEASUREMENTS: The primary outcome was patient-reported pain using the 10-point Brief Pain Inventory. Functional outcome was measured using the Majeed pelvic score. Outcomes were analyzed using hierarchical Bayesian models to compare the average treatment effect from injury to 12 and 52 weeks postinjury. The probability of the mean treatment benefit exceeding a clinically important difference was determined. RESULTS: The 3-month average treatment effect of surgery compared with nonoperative management was a 1.2-point reduction in pain [95% credible interval (CrI): 0.4-1.9] and an 8% absolute improvement in the Majeed score (95% CrI: 3%-14%). Similar results persisted to 1 year. Patients with initial fracture displacement ≥5 mm experienced a larger reduction in pain (2.2, 95% CrI: 0.9-3.5) compared with those patients with less initial displacement (0.9, 95% CrI: 0.1-1.8). CONCLUSION: On average, surgical fixation likely provides a small improvement in pain and functional outcome for up to 12 months. Patients with ≥5 mm of posterior pelvic ring displacement are more likely to experience clinically important improvements in pain. LEVEL OF EVIDENCE: Therapeutic Level II. See Instructions for Authors for a complete description of levels of evidence.

Benzoyl peroxide use transiently decreases Cutibacterium acnes load on the shoulder.

BACKGROUND: Cutibacterium acnes is the most common pathogen in shoulder prosthetic joint infections. Short-contact benzoyl peroxide (BPO) solutions effectively reduce C acnes loads on the shoulder preoperatively. It is unknown how long the effect of BPO lasts. We evaluated C acnes counts 1 week after BPO application. We hypothesized that BPO would decrease C acnes burden with a rebound after 1 week. METHODS: Screening of 102 healthy volunteers with no history of shoulder surgery or C acnes infection was performed to establish bacterial counts. Thirty-four participants were selected based on an established threshold. Each was given BPO 5% for 3 consecutive days of application on either the left or right shoulder as indicated by a random number generator. Deep sebaceous gland cultures were obtained with a detergent scrub technique before BPO application, after 3 days of use, and 1 week after BPO treatment commenced. RESULTS: The differences between the logarithmic reduction and the logarithmic rebound at the anterior, lateral, and posterior sites were statistically significant. Anteriorly, the average log reduction was -0.44 and the average log rebound was 0.69 (P = .003). Laterally, reduction was -0.64 and rebound was 0.74 (P = .003). Posteriorly, reduction was -0.63 and rebound was 0.78 (P = .008). At the axilla, reduction was -0.40 and rebound was 0.31 (P = .10). The differences in C acnes burden between pretreatment and 1-week counts at all sites were not statistically significant. CONCLUSION: A significant decrease in C acnes burden occurred after BPO application but was not permanent. Significant rebound occurred just 1 week later.

"I Knew I Could Make a Difference": Motivations and Barriers to Engagement in Fighting the West African Ebola Outbreak Among U.S.-Based Health Professionals.

The 2014 West African Ebola outbreak was unprecedented in scale and required significant international assistance. Many U.S.-based health professionals traveled to West Africa to participate in the response, whereas others considered participation, but ultimately decided against it. This study explores motivators, facilitators, and barriers to international health care worker mobilization. We conducted 24 semistructured in-depth interviews and one focus group discussion with clinical and nonclinical responders and nonresponders. Responders reported feeling duty-bound to help, confidence in their training, and prior experience in humanitarian response. Media coverage was perceived to create environments of stigma and misinformation. Supportive workplaces and clear leave of absence policies facilitated engagement, whereas unsupportive workplaces posed barriers. Although nonresponders were included in the study, the dynamics of nonresponse were less clear and warrant further exploration. Understanding how to support health professionals in responding to outbreak situations may improve mobilization in future public health crises.

HIV Treatment Cascade by Housing Status at Enrollment: Results from a Retention in Care Cohort.

Though housing instability is linked to poor HIV health outcomes, studies that assess the HIV treatment cascade by housing status are limited. Using data from a multi-site Retention in Care initiative we constructed HIV treatment cascades for participants (n = 463) of five grantee sites. We found no significant differences in viral suppression at follow-up among participants who were unstably housed at enrollment (49%) as compared to those who were stably housed at enrollment (54%). Among participants with available data at 6- or 12-month follow-up, 94% were engaged in care, 90% were retained in, 94% were on ART, and 71% had suppressed viral load. Some site-level differences were noted; at two of the sites participants who were stably housed were more likely to be retained in care and on ART. Overall, findings demonstrated that participants moved successfully through the HIV treatment cascade regardless of housing status at enrollment, suggesting that evidence-based support and services to help people living with HIV/AIDS can help mitigate barriers to engagement in care associated with lack of stable housing.

Pulmonary arterial hypertension and atrial arrhythmias: incidence, risk factors, and clinical impact.

Atrial arrhythmia (AA) occurrence in pulmonary arterial hypertension (PAH) may determine clinical deterioration and affect prognosis. In this study we assessed AA incidence in idiopathic (IPAH) and systemic sclerosis related PAH (SSc-PAH) and evaluated risk factors, management, and impact on mortality. We collected baseline data from consecutive IPAH or SSc-PAH patients prospectively enrolled in the Johns Hopkins Pulmonary Hypertension Registry between January 2000 and July 2016. During follow-up AA onset, treatment, and outcome were recorded. Among 317 patients (201 SSc-PAH, 116 IPAH), 42 developed AA (19 atrial fibrillation, 10 flutter-fibrillation, 9 atrial flutter, and 4 atrial ectopic tachycardia) with a 13.2% cumulative incidence. Most events were associated with hospitalization (90.5%). Electrical or pharmacological cardioversion was attempted in most cases. Patients with AA had higher right atrial pressure, pulmonary wedge pressure ( P < 0.005), NT-proBNP ( P < 0.05), and thyroid disease prevalence ( P < 0.005). Higher mortality was observed in patients with AA, though not statistically significant (LogRank P = 0.323). Similar long-term mortality between IPAH with AA and SSc-PAH without AA was observed (LogRank P = 0.098). SSc-PAH with AA had the worst prognosis. In PAH patients AA occurrence is a matter of significant concern. Therapeutic strategies aimed at restoring sinus rhythm may represent an important goal.

Cost-Utility of Access to Care, a National HIV Linkage, Re-engagement and Retention in Care Program.

Linkage to HIV medical care and on-going engagement in HIV medical care are vital for ending the HIV epidemic. However, little is known about the cost-utility of HIV linkage, re-engagement and retention (LRC) in care programs. This paper presents the cost-utility analysis of Access to Care, a national HIV LRC program. Using standard methods from the US Panel on Cost-Effectiveness in Health and Medicine, we calculated the cost-utility ratio. Seven Access to Care programs were cost-effective and two were cost-saving. This study adds to a small but growing body of evidence to support the cost-effectiveness of LRC programs.

Barriers and Facilitators to the Implementation of a National HIV Linkage, Re-Engagement, and Retention in Care Program.

The 2020 National HIV AIDS Strategy (NHAS) sets a target of 90% of diagnosed people living with HIV (PLWH) retained in HIV care. Access to Care (A2C) was a national HIV linkage, re-engagement, and retention in care program funded by AIDS United with support from the Corporation for National and Community Service that aimed to link and retain the most vulnerable PLWH into high-quality HIV care. This study explores the barriers and facilitators of implementing the A2C program from the perspective of program staff. Ninety-eight qualitative interviews were conducted with staff at implementing organizations over the 5 years of the project. Barriers included challenges with recruiting and retaining participants, staffing and administration, harmonizing partnerships, and addressing the basic and psychosocial needs of participants. Facilitators included strong relationships with partner organizations, flexible program models, and the passion and dedication of staff. Findings will inform the development of future programs and policy.

The Cost and Threshold Analysis of Retention in Care (RiC): A Multi-Site National HIV Care Program.

Persons diagnosed with HIV but not retained in HIV medical care accounted for the majority of HIV transmissions in 2009 in the United States (US). There is an urgent need to implement and disseminate HIV retention in care programs; however little is known about the costs associated with implementing retention in care programs. We assessed the costs and cost-saving thresholds for seven Retention in Care (RiC) programs implemented in the US using standard methods recommended by the US Panel on Cost-effectiveness in Health and Medicine. Data were gathered from accounting and program implementation records, entered into a standardized RiC economic analysis spreadsheet, and standardized to a 12 month time frame. Total program costs for from the societal perspective ranged from $47,919 to $423,913 per year or $146 to $2,752 per participant. Cost-saving thresholds ranged from 0.13 HIV transmissions averted to 1.18 HIV transmission averted per year. We estimated that these cost-saving thresholds could be achieved through 1 to 16 additional person-years of viral suppression. Across a range of program models, retention in care interventions had highly achievable cost-saving thresholds, suggesting that retention in care programs are a judicious use of resources.

The Global Engagement in Care Convening: Recommended Actions to Improve Health Outcomes for People Living With HIV.

The National HIV AIDS Strategy (NHAS) calls for a more coordinated response to the HIV epidemic. The Global Engagement in Care Convening created a forum for domestic and international experts to identify best practices in HIV care. This manuscript summarizes the meeting discussions and recommendations from meeting notes and an audio recording of the meeting. Recommendations include: further standardization of performance goals and performance measures; additional research; a more robust system to support competing needs of clients receiving services; electronic information exchanges for HIV-related data; an expansion of the role of other health professionals to extend the capacity of physicians and other members of the care team; and revisions to current financing systems to increase reimbursement for and access to services that promote linkage to and retention in HIV care. The recommendations provide a unique example of "reverse technical assistance" and will inform U.S. program development, research, and policy.
