Unplanned Return to Hospital After Same Day Oral Cavity Resection: A Dual Institution Study

OBJECTIVES

Primary objective: describe rates of 30-days unplanned readmission following outpatient resection of oral cavity cancer. Secondary objective: evaluate for patient and treatment factors associated with readmission.

METHODS

Retrospective, dual-institution cohort study of 2 tertiary care referral centers involving adult patients undergoing resection of oral cavity cancer with plans for same-day discharge. Consecutive sample of 77 patients included. Primary outcome was unplanned readmission to emergency room or inpatient stay in the 30 days following surgery. Comparison testing was used between return and non-return groups.

RESULTS

Among 77 patients treated with outpatient surgery for oral cavity cancer, 19 (25%) returned to the hospital within 30 days. Among the reasons for return, 16 (80%) were directly related to surgery, and 4 (20%) were related to perioperative medical complications not directly related to a surgical site. Among the 25 patients also undergoing sentinel lymph node biopsy with their oral cavity resection, none returned to the hospital for neck-related complications. While most patients could be safely observed and discharged after return to the hospital, 8 patients (10%) required inpatient readmission. No significant differences between return and non-return groups were identified, although there was a trend toward shorter driving distance from hospital for the return group (47.6 miles vs. 69.5 miles, P = 0.097).

CONCLUSION

Unplanned return to the hospital following outpatient oral cavity resection is prevalent and primarily driven by postoperative primary resection site concerns. Among patients selected for same day discharge, no definite population at highest risk of unplanned return was identified.

Is Continued Perioperative Antithrombotic Therapy Safe When Performing Open Tracheostomy?

OBJECTIVES

To date, there are no specific guidelines on antithrombotic therapy (ATT) management, which includes both anticoagulation and antiplatelet medications, for open tracheostomy. The objective of this study was to evaluate whether the use of perioperative antithrombotic medication during open tracheostomy influences the incidence of perioperative or postoperative complications.

METHODS

A retrospective review was conducted of all patients who underwent open tracheostomies at a tertiary care medical center from January 2015 to December 2019. Charts were reviewed for demographics, comorbidities, indication for tracheostomy, ATT use, operative details, and complications.

RESULTS

A total of 217 tracheostomies were evaluated for this study, of which 148 (68.2%) were not on ATT and 69 (31.8%) were on ATT during surgery. No significant difference was observed based on ATT status in perioperative bleeding (P = .983), postoperative bleeding (P = .24), or median days to decannulation (P = .5986). ATT patients were 2.67 times more likely to experience 30-day mortality than those non-ATT patients (P = .035). There was only one death due to hemorrhage in the ATT group. This was unrelated to the tracheostomy. This compares to 2 hemorrhage-related deaths in those not on ATT.

CONCLUSION

There was no significant difference in perioperative or postoperative bleeding based on ATT use. Patients on ATT were significantly more likely to experience 30-day mortality, however only one death was due to hemorrhage in the ATT group and was unrelated to tracheostomy. Therefore, continued perioperative ATT use appears to be safe when performing open tracheostomy.

Complications Following Endoscopic and Open Trigger Finger Release: A Retrospective Comparative Study

BACKGROUND

Open trigger finger release (OTFR) and endoscopic trigger finger release (ETFR) are effective methods in treating stenosing tenosynovitis. However, a paucity of literature exists comparing the techniques. This study describes and compares postoperative complications following OTFR and ETFR at a single institution.

METHODS

Patients undergoing trigger finger release between 2018 and 2020 within a single institution were identified. Electronic medical records were reviewed for patient demographics, surgical history, surgical characteristics, and clinical outcomes. Major and minor postoperative complications were assessed. Secondary outcome measures included tourniquet time and procedure time. Statistical analysis evaluated associations between postoperative complications, surgical technique, patient demographics, and surgical characteristics.

RESULTS

In total, 57 patients (80 digits) were included in the study: 42 digits treated with OTFR and 38 digits treated with ETFR. Mean follow-up time was 57.6 ± 69.0 days (range, 7-307 days) for ETFR and 34.2 ± 26.3 days (range, 6-120 days) for OTFR. Overall, major, and minor complication rates for the cohort were 8.8%, 1.8% and 7.0%, respectively. There were no major complications following ETFR and 1 following OTFR (4%), the isolated case being postoperative Chronic regional pain syndrome. Minor complication rates were similar following OTFR (8%) and ETFR (6%). Persistent digit stiffness and swelling were found to be the most prevalent minor complications (n = 2, respectively), followed by wound dehiscence (n = 1). Female patients were significantly more likely to experience postoperative complications.

CONCLUSIONS

Major complications following trigger finger release are unlikely; however, minor complications are prominent. Patients treated with OTFR and ETFR showed similar postoperative complication rates. Continued investigations into the benefits of ETFR are warranted.

Impact of Insurer on Papillary Thyroid Carcinoma Outcomes, Stage, and Treatment Modalities

BACKGROUND

While the impact of insurance has been described for thyroid cancer as a whole, we sought to further characterize this relationship for the papillary sub-group (PTC).

METHODS

Those patients with primary site thyroid tumors from 2007 to 2016 with histology-confirmed PTC were extracted from the SEER database. These parameters yielded 103 219 participants for demographic, extent of disease, and treatment parameter study and 103 025 for outcome studies.

RESULTS

Compared to their counterparts, those with Medicaid were more likely to have stage T3 or greater (<.0001) disease at presentation. Those with Medicare/private insurance were more likely to have No staging at diagnosis (P < .0001). Similarly, those with Medicaid exhibited poorer overall (98.0%, 90.9%, 81.6% vs 98.9%, 95.0%, 90.0%; P < .0001) and cause-specific (99.3%, 98.0%, 95.8% vs 99.7%, 99.1%, 98.4%; P < .0001) survival after 1, 5, and 9 years respectively.

CONCLUSION

Insurer has a significant impact on the stage at diagnosis of papillary thyroid carcinoma while having limited effect on the treatment modalities offered. Statistically significant overall and cause-specific mortality differences were appreciated but are likely clinical insignificant. Further work to elucidate the social factors likely affecting these patients is warranted.

The Long-term Effect of Inferior Turbinate Surgery Techniques on Nasal Obstruction and Quality of Life

OBJECTIVE

The aim of the study was to compare the long-term effects of radiofrequency ablation (RFA), microdebrider-assisted inferior turbinoplasty (MAIT), and diode laser techniques on the severity of nasal obstruction and quality of life (QOL) in a 3-year follow-up.

METHODS

The patients filled a Visual Analog Scale (VAS) regarding the severity of nasal obstruction and the Glasgow Health Status Inventory (GHSI) questionnaire preoperatively and during the control visits at 3 months and 3 years. Acoustic rhinometry was also performed. A total of 78 patients attended both control visits.

RESULTS

All 3 techniques improved the VAS score for the severity of nasal obstruction and the GHSI total score significantly compared to the preoperative values at both 3 months and 3 years. Compared to the preoperative values, all 3 techniques increased the V2 to 5 cm values significantly at 3 months. After 3 years, compared to the preoperative values, the MAIT (P = .005) and diode laser (P < .001) still had a statistically significant volume increase in V2 to 5 cm, whereas the RFA (P = .06) did not achieve a statistically significant effect.

CONCLUSION

The RFA, MAIT, and diode laser all improved both the patients' subjective sensation of the severity of nasal obstruction and QOL significantly. The response was sustained during the 3-year follow-up period with all 3 techniques. A weakening in the objective treatment response to RFA was found in the longer follow-up, but that did not cause a weakening of the patients' subjective treatment response.

Colorectal cancer databases and registries in Australia: what data is available?

BACKGROUND

There are multiple data sources relating to colorectal cancer (CRC) nationwide. Prospective clinical cancer databases, population-based registries and linked administrative data are powerful tools in clinical outcomes research and provide real-world perspective on cancer treatments. This study aims to review the different Australian data sources for CRC from the perspective of conducting comparative research studies using a PICO (patient, intervention, comparison, outcome) framework.

METHODS

Data dictionaries from the different data sources were evaluated for the types of exposure and outcome variables contained to highlight their differing research utility.

RESULTS

State or territory-based cancer registries contain limited histology, cancer staging and treatment detail. They enable investigation of population-level patterns in overall survival (OS) of cancer patients with different demographics. Prospective clinical cancer databases contain more detail, especially surgical. Their strength is in auditing short-term surgical outcomes. They vary in the amount of data collected for other cancer treatments and completion of follow up data. Linked administrative databases have broad population coverage but less surgical detail. They provide population-level data on treatment patterns, short-term outcome measures and OS, as well as long-term surgical outcomes such as identifying patients who did not undergo stoma reversal. These databases cannot assess disease-free survival.

CONCLUSION

Of the various CRC data sources within Australia, linked administrative databases have the potential to provide the widest population coverage combined with the broadest range of exposures and outcomes, and arguably the most research utility.

Transmastoid Hydroxyapatite Resurfacing for Sigmoid Sinus Wall Anomalies Causing Pulsatile Tinnitus

OBJECTIVE

Comprising 4% of tinnitus, pulsatile tinnitus (PT) can be particularly difficult for affected patients as well as surgeons looking to address their symptoms. Often the cause is not identified but can be secondary to turbulent flow in or near the sigmoid sinus, particularly if there is an identifiable sigmoid sinus dehiscence (SSDe) and/or diverticulum (SSDi). These sigmoid sinus wall anomalies (SSWA) may be treated with transmastoid sigmoid sinus resurfacing; however, this intervention remains relatively novel and its technique, materials used, resolution success, and complications need to be continuously reviewed.

METHODS

A retrospective case series of patients with PT due to SSWA at a tertiary referral center was reviewed. A total of 6 patients (7 ears) treated by transmastoid resurfacing using hydroxyapatite (HA) were retrospectively assessed. Pre-operative demographics and symptoms, pre- and post-operative hearing results, and post-operative outcomes were reviewed.

RESULTS

All patients were female with an average BMI of 32.9 (±5.4) and a mean age of 45.5 years (±15.3). Mean follow-up was 648 days. Objective tinnitus was noted in all ears with SSDi (100%); however, no objective tinnitus was noted with purely SSDe. In 100% of ears, PT was diminished with ipsilateral jugular compression and was amplified with contralateral head turn. Pre-operative symptoms of PT resolved in all patients, but delayed recurrence (>1 year) occurred in 1 ear (14%). No patient had pre- or post-operative hearing loss. No major complications were encountered.

CONCLUSIONS

Transmastoid resurfacing for SSWA with HA bone cement is a safe, reliable intervention in properly identified PT patients.

Expiratory Muscle Strength Training in patients After Total Laryngectomy; A Feasibility Pilot Study

OBJECTIVES

Expiratory muscle strength training (EMST) is a threshold based device-driven treatment for improving expiratory pressure. EMST proved to be effective in different patient groups to improve cough function. To date, EMST has not been tested in the total laryngectomy population (TL).

METHODS

This prospective, randomized case-series study examined feasibility, safety, and compliance of EMST in a group of TL participants and its effects on pulmonary function, physical exertion, fatigue, and vocal functioning. Ten TL participants were included in the study to perform a 4 till 8 weeks of EMST. Objective and subjective outcome measures included manometry, spirometry, cardio pulmonary exercise testing (CPET), voice recordings, and patient reported outcome measures. Group means were reported and estimates of the effect are shown with a 95% confidence interval, using single sample t-tests.

RESULTS

Nine participants completed the full study protocol. Compliance to the training program was high. All were able to perform the training, although it requires adjustments of the device and skills of the participants. Maximum expiratory pressure (MEP) and vocal functioning in loudness improved over time. After EMST no changes were seen in other objective and subjective outcomes.

CONCLUSIONS

EMST appears to be feasible and safe after total laryngectomy. MEP improved over time but no improvement in the clinically relevant outcome measures were seen in this sample of relatively fit participants. Further investigation of the training in a larger group of participants who report specifically pulmonary complaints is recommended to investigate if the increase in MEP results in clinical benefits.

Evaluation of Acupuncture's Efficacy Within Otolaryngology

OBJECTIVES

Acupuncture is a form of Traditional Chinese Medicine that has minimal side effects, is cost-effective, can be easily administered, and may serve as a useful non-pharmaceutical therapy for certain conditions. However, studies and clinical practice guidelines are inconsistent in conclusions and recommendations about acupuncture. This qualitative review addresses the evidence available for acupuncture use in otolaryngology.

METHODS

A literature review was completed using EMBASE, PubMed, and The Cochrane Collection for conditions within otolaryngology that have used and studied the comparative effects of acupuncture. Thirty studies ultimately fit the inclusion criteria and were used for this qualitative review.

RESULTS

Studies included in this review contained a variety of conditions within otolaryngology, including allergic rhinitis, chronic rhinitis, tinnitus, sudden sensorineural hearing loss, post-viral olfactory dysfunction, dysphonia, and tonsillectomies.

CONCLUSION

Given its safety profile, cost, and perceived benefit, recommendations and guidelines supporting acupuncture as an alternative or adjunctive therapy are surfacing for certain conditions such as allergic rhinitis. However, stronger conclusions with specific recommendations are limited by varied methodology between majority of the studies. Additional high-quality randomized control studies with low risk of bias are required to continue to assess the effects of acupuncture in the field of otolaryngology before stronger recommendations can be made on other conditions.

Registries for study of nonmalignant hematological diseases: the example of the Severe Chronic Neutropenia International Registry

PURPOSE OF REVIEW

Registries provide 'real world' perspectives on the natural history and outcomes for many clinical conditions. The purpose of this review is to identify registries for nonmalignant hematological disease and to describe the operation of a successful long-term registry for patients with severe chronic neutropenia.

RECENT FINDINGS

There was an upswing in registries about 20 years ago, based on optimism about their utility to improve patient care. To show value, registries must define outcomes for populations of patients with specific medical conditions and the effects of treatment. This is challenging for many reasons. The Severe Chronic Neutropenia International Registry is an example of a successful registry. This report describes underlying reasons for its success.

SUMMARY

Registries are important to organize and analyze clinical information across geographic, ethnic and social boundaries. They are also challenging to organize, administer and support.

A Single Visualization Technique for Displaying Multiple Metabolite-Phenotype Associations

To assist with management and interpretation of human metabolomics data, which are rapidly increasing in quantity and complexity, we need better visualization tools. Using a dataset of several hundred metabolite measures profiled in a cohort of ~1500 individuals sampled from a population-based community study, we performed association analyses with eight demographic and clinical traits and outcomes. We compared frequently used existing graphical approaches with a novel ‘rain plot’ approach to display the results of these analyses. The ‘rain plot’ combines features of a raindrop plot and a conventional heatmap to convey results of multiple association analyses. A rain plot can simultaneously indicate effect size, directionality, and statistical significance of associations between metabolites and several traits. This approach enables visual comparison features of all metabolites examined with a given trait. The rain plot extends prior approaches and offers complementary information for data interpretation. Additional work is needed in data visualizations for metabolomics to assist investigators in the process of understanding and convey large-scale analysis results effectively, feasibly, and practically.

Arthroplasty implant registries over the past five decades: Development, current, and future impact

Local, regional, and national registries have played an important role in the development of hip and knee arthroplasty and the treatment of patients with various maladies of these joints. Four arthroplasty registries stand out as leading forces behind the drive to popularize the use of registries and pursue the concept of evidence based medicine. The Mayo registry, started by Mark Coventry, is recognized as the oldest continuing registry for arthroplasty. The Harris Registry at Massachusetts General Hospital, along with the Mayo Registry, has greatly contributed to the advancement of arthroplasty surgery and have served an important role of identifying poorly performing implants and techniques in the United States. The Swedish Knee Arthroplasty Registry is the oldest national registry dedicated to joint arthroplasty and along with the Swedish Hip Arthroplasty Registry have established the infrastructure, analysis and reporting mechanisms, and leadership that has enabled other countries to subsequently develop national registries around the world. As more countries have adopted the concept of national registries, a new area of research is possible by pooling the resources of large registries as is now occurring with the Nordic countries. Several international organizations have been formed to promote future collaboration and develop international standards. The process of globalization of registries is a result of continued efforts over the past 50 years in improving and disseminating the knowledge gained from the early registries. © 2018 Orthopaedic Research Society.

No difference between mechanical perturbation training with compliant surface and manual perturbation training on knee functional performance after ACL rupture

Manual perturbation training improves dynamic knee stability and functional performance after anterior cruciate ligament rupture (ACL-rupture). However, it is limited to static standing position and does not allow time-specific perturbations at different phase of functional activities. The purpose of this study was to investigate whether administering mechanical perturbation training including compliant surface provides effects similar to manual perturbation training on knee functional measures after an acute ACL-rupture. Sixteen level I/II athletes with ACL-ruptures participated in this preliminary study. Eight patients received mechanical (Mechanical) and eight subjects received manual perturbation training (Manual). All patients completed a functional testing (isometric quadriceps strength, single-legged hop tests) and patient-reported measures (Knee Outcome Survey-Activities of Daily Living Scale (KOS-ADLS), Global Rating Score (GRS), International Knee Documentation Committee 2000 (IKDC 2000) at pre- and post-training. 2 × 2 ANOVA was used for data analysis. No significant group-by-time interactions were found for all measures (p > 0.18). Main effects of time were found for single hop (Pre-testing: 85.14% ± 21.07; Post-testing: 92.49% ± 17.55), triple hop (Pre-testing: 84.64% ± 14.17; Post-testing: 96.64% ± 11.14), KOS-ADLS (Pre-testing: 81.13% ± 11.12; Post-testing: 88.63% ± 12.63), GRS (Pre-testing: 68.63% ± 15.73; Post-testing: 78.81% ± 13.85), and IKDC 2000 (Pre-testing: 66.66% ± 9.85; Post-testing: 76.05% ± 14.62) (p < 0.032). Administering mechanical perturbation training using compliant surfaces induce effects similar to manual perturbation training on knee functional performance after acute ACL-rupture. The clinical significance is both modes of training improve patients' functional-performance and limb-to-limb movement symmetry, and enhancing the patients' self-reported of knee functional measures after ACL rupture. Mechanical perturbation that provides a compliant surface might be utilized as part of the ACL rehabilitation training. © 2017 Orthopaedic Research Society. Published by Wiley Periodicals, Inc.

The Quality In-Training Initiative: Giving Residents Data to Learn Clinical Effectiveness

BACKGROUND

Training programs are expected to provide clinical outcomes data to residents. Few systems have the necessary infrastructure. We evaluated initial adoption and use of the Quality In-Training Initiative (QITI) platform linking National Surgical Quality Improvement Program (NSQIP) data to trainees.

STUDY DESIGN

Proportions of Accreditation Council for Graduate Medical Education general surgery residency programs with differing levels of NSQIP and QITI affiliation were calculated and program characteristics were compared. All NSQIP sites that captured QITI custom field data from July 2013 to June 2016 were included in case analysis. Differences in case collection were compared between participating (P) sites that actively participated in QITI and nonparticipating (NP) sites that did not. Resident participation by procedure type was examined.

RESULTS

Of 268 accredited general surgery residency programs, 92% (n = 248) is affiliated with a NSQIP hospital and 61% of all clinical months is spent at NSQIP sites. For 42% of all programs (n = 114), the primary teaching hospital is affiliated with the QITI. In all, 74 P sites and 89 NP sites captured a total of 417,816 cases. The median number of cases captured per site was statistically higher for P sites (3063) compared with NP sites (2307, p < 0.001). A total of 68.3% of all cases captured had resident participation indicated by postgraduate year (n = 285,469). The most common procedures with resident participation were laparoscopic appendectomy (n = 17,082, 6.0%) and laparoscopic cholecystectomy (n = 15,502, 5.4%). Percentage coverage rates ranged from 17.3% to 91.8%.

CONCLUSION

Most general surgery rotations are at NSQIP sites. Identifying resident participation in captured NSQIP cases is feasible on a large scale. Captured cases reflect national case-mix. The platform has the potential to collect data on institutional and program-level variation in resident operative experience that may be used to improve training.

Resident Involvement in Microsurgery: An American College of Surgeons National Surgical Quality Improvement Program Analysis

OBJECTIVE

In the current healthcare climate, there is increased focus on medical errors, patient outcomes, and the influence of resident participation on these metrics. Other studies have examined the influence of resident involvement on surgical outcomes, but the arena of microsurgery, with added complexity and learning curve, has yet to be investigated.

DESIGN

A retrospective analysis of the American College of Surgeons National Surgical Quality Improvement Program database was performed to find patients undergoing procedures with free tissue transfer by screening for Current Procedural Terminology codes. Primary outcomes measured include flap failure, wound, infectious, and major and minor complications.

SETTING

This study was conducted at the Methodist Hospital, an academic hospital located in Houston, Texas.

PARTICIPANTS

Patients in the National Surgical Quality Improvement Program database between the years 2005 and 2012 undergoing microsurgical procedures were included in this analysis.

RESULTS

A total of 1466 patients met inclusion criteria. There was a statistically significant association of major complications with age, peripheral vascular disease, American Society of Anesthesiologists (ASA) classification of 3 or greater, total operative time, and year of operation. Multivariate analysis on minor complications demonstrated significant association with ASA class of 3 or 4. Resident involvement was not a significant factor among any outcome measures including major complications, minor complications, flap failure, wound complications, infectious complications, bleeding requiring transfusion, and unexpected reoperation rates within 30 days.

CONCLUSIONS

This study provides further evidence in support of the claim that resident involvement in microsurgery is safe and effective, with similar rates of major complications, minor complications, flap failure, and unexpected reoperation. High ASA classification and history of peripheral vascular disease were strong predictors of major complications and should be optimized preoperatively before free tissue transfer. Later years were associated with decreased major complication rates, which may be reflective of enhanced supervision standards.

External Auditory Canal Foreign Body Extraction Outcomes

OBJECTIVES

To compare pediatric external auditory canal (EAC) foreign body extraction outcomes by clinical setting and identify factors predictive of successful removal.

METHODS

Retrospective review of pediatric patients with EAC foreign bodies to a single institution emergency department (ED) and otolaryngology clinic (OTO) between January 2010 and April 2015. Patient characteristics, foreign body type, removal attempts, instrumentation utilized, and complications were evaluated with respect to clinical setting and patient outcome.

RESULTS

In all, 1197 patients with EAC foreign bodies were identified, 759 (63%) of whom presented primarily to the ED. Successful removal was achieved in OTO in 92.9% of cases and the ED in 67.9% of cases. Beads and spherical objects had the overall lowest rates of successful removal. Likelihood of removal decreased significantly after one unsuccessful attempt. Complications were reported in 35.7% of patients undergoing removal in the ED and 5.0% of patients undergoing removal in the otolaryngology clinic.

CONCLUSIONS

Patients commonly present to the ED for removal of EAC foreign bodies. Referral to an otolaryngologist is recommended if the object is spherical or after one unsuccessful attempt at removal.

Mucosal Sparing Radiation Therapy in Resected Oropharyngeal Cancer

PURPOSE

To report the outcomes of patients with favorable risk oropharyngeal cancer that underwent adjuvant radiation therapy with omission of the primary site from the clinical target volume (CTV).

MATERIAL/METHODS

A retrospective study of 40 patients treated with transoral surgery (TOS) followed by neck only radiation using intensity modulated radiation therapy (IMRT) with exclusion of the primary site. For all patients, a CTV of the primary surgical bed was contoured to obtain the estimated incidental dose to the primary site.

RESULTS

Median follow-up was 51 months (range, 13-155 months). The median radiation therapy (RT) dose to the neck was 6000 cGy (range, 5400-6400 cGy). The mean incidental dose to the primary tonsillar site was 4320 cGy (SD ± 480 cGy) and to the primary base of tongue site was 4060 cGy (SD ± 420 cGy). There were no local failures and only 1 regional failure, resulting in 97.5% locoregional control rate at 4 years. Two patients developed distant metastases, without evidence of locoregional recurrence, for a 4-year overall survival rate of 97%.

CONCLUSIONS

Our analysis suggests that mucosal sparing RT after TOS in favorable risk oropharyngeal cancer patients may provide comparable oncologic and improved functional outcomes compared to conventional treatment in selected patients.

Psychometric evaluation of the Work Readiness Questionnaire in schizophrenia

OBJECTIVE/INTRODUCTION

Unemployment can negatively impact quality of life among patients with schizophrenia. Employment status depends on ability, opportunity, education, and cultural influences. A clinician-rated scale of work readiness, independent of current work status, can be a valuable assessment tool. A series of studies were conducted to create and validate a Work Readiness Questionnaire (WoRQ) for clinicians to assess patient ability to engage in socially useful activity, independent of work availability.

METHODS

Content validity, test-retest and inter-rater reliability, and construct validity were evaluated in three separate studies.

RESULTS

Content validity was supported. Cronbach's α was 0.91, in the excellent range. Clinicians endorsed WoRQ concepts, including treatment adherence, physical appearance, social competence, and symptom control. The final readiness decision showed good test-retest reliability and moderate inter-rater reliability. Work readiness was associated with higher function and lower levels of negative symptoms. Low positive and high negative predictive values confirmed the concept validity.

DISCUSSION

The WoRQ has suitable psychometric properties for use in a clinical trial for patients with a broad range of symptom severity. The scale may be applicable to assess therapeutic interventions. It is not intended to assess eligibility for supported work interventions.

CONCLUSIONS

The WoRQ is suitable for use in schizophrenia clinical trials to assess patient work functional potential.

Coronary artery disease risk reduction in HIV-infected persons: a comparative analysis

Despite an increased risk of coronary artery disease (CAD) in persons infected with human immunodeficiency virus (HIV), few data are available on primary prevention of CAD in this population. In this retrospective cohort study, HIV-infected patients treated in an academic medical center HIV Specialty Clinic between 1996 and 2010 were matched by age, gender, and ethnicity to a cohort of presumed uninfected persons followed in an academic medical center Internal Medicine primary care clinic. We compared CAD primary prevention care practices between the two clinics, including use of aspirin, HMG-CoA reductase inhibitors ("statins"), and anti-hypertensive drugs. CAD risk between the two groups was assessed with 10-year Framingham CAD risk scores. In the comparative analysis, 890 HIV-infected persons were compared to 807 controls. Ten-year Framingham CAD Risk Scores were similar in the two groups (median, 3; interquartile range [IQR], 0-5). After adjusting for relevant risk factors, HIV-infected persons were less likely to be prescribed aspirin (odds ratio [OR] 0.53; 95% confidence interval [CI], 0.40-0.71), statins (OR, 0.70; 95% CI, 0.53-0.92), and anti-hypertensive drugs (OR, 0.63; 95% CI, 0.50-0.79) than persons in the control group. In summary, when compared to demographically similar uninfected persons, HIV-infected persons treated in an HIV specialty clinic were less likely to be prescribed medications appropriate for CAD risk reduction. Improving primary preventative CAD care in HIV specialty clinic populations is an important step toward diminishing risk of heart disease in HIV-infected persons.
