Incentives and individualized coaching improve completion rates of supervised exercise therapy for claudication.

OBJECTIVE: Supervised exercise therapy (SET) provides clinical benefit for patients suffering from intermittent claudication and has been widely recommended as first-line therapy before endovascular or surgical intervention. However, published rates of SET program completion range from 5% to 55%, with historic completion of 54% at our own institution. As such, we sought to identify if targeted patient-supportive interventions improve SET completion rates while still maintaining efficacious SET programming. METHODS: Patients who were diagnosed with intermittent claudication, as defined by ankle-brachial index (ABI) <0.9 without rest pain, were offered enrollment in a prospective quality improvement protocol for our 12-week SET for peripheral artery disease program. Program completion was defined as ≥24 of 36 offered sessions over 12 weeks. A three-pronged approach was utilized to improve completion during the study, including financial incentives up to $180, scheduled coaching with our advanced practitioner staff, and informational materials on the importance of SET programming and lifestyle modification. Patient-reported improvements in walking symptoms were tracked via regularly administered questionnaires. Functional measures of SET programming including total walking duration and distance, metabolic equivalent of task, and ABIs; vascular intervention within 12-months after enrollment was also collected and compared using univariate paired analysis. RESULTS: In total, seventy-three patients were enrolled in SET for peripheral artery disease programming over the study period. Utilizing our three-pronged coaching approach, 56 patients completed SET programming, increasing our SET completion rate to 76.7% over a 2-year study period. Compared with pre-SET baseline, patients who completed SET noted less pain, aching, cramps in calves when walking (P = .004), and less difficulty walking 1 block (P = .038). Additionally, patients significantly increased their metabolic equivalent of task (3.1 vs 2.6; P < .001), total walking duration (30 mins vs 13.5 mins; P < .001), and total walking distance (0.7 vs 0.3 miles; P < .001) from their pre-SET baseline. There were no changes in participant ABIs from enrollment to completion in participants. Patients who completed SET programming also delayed vascular intervention compared with those who did not complete SET or declined participation (213.5 vs 122.5 days from enrollment; P = .041). CONCLUSIONS: Targeted incentives, including cost-coverage vouchers and personalized coaching with instructional materials, successfully improved patient completion of a prescribed SET program. Patients who completed SET programming reported subjective improvement in walking symptoms and objective walking benefits. In addition, these patients had delayed time to vascular intervention, supporting current vascular guidelines advocating for effective SET therapy prior to offering vascular intervention for intermittent claudication.

Patient Reported Barriers for Participation in Supervised Exercise Therapy for Symptomatic Peripheral Artery Disease.

BACKGROUND: Supervised exercise therapy (SET) provides clinical benefit for patients suffering from intermittent claudication due to peripheral artery disease (PAD). However, enrollment in programs when offered remains low. We sought to identify patient-reported barriers to enrollment in SET as part of a prospective quality improvement program. METHODS: Patients who presented to clinic and were diagnosed with claudication were offered enrollment in a prospective quality improvement protocol, offered at 9 regional offices throughout our health system. Both patients who enrolled and declined enrollment were offered a 12-question questionnaire to identify potential barriers to enrollment. Additional data including gender, smoking status, ankle-brachial index (ABI), proximity to the nearest regional office, and disadvantage levels of neighborhoods (low: 1-3, medium: 4-7, and high: 8-10 area deprivation index [ADI]) was collected and compared by program participation using univariate analysis. RESULTS: Patients enrolled in the SET program (n = 66 patients) versus those who declined (n = 84 patients) were of similar age (medium age: 71.4 vs. 69.7 years, P = 0.694), baseline ABI (0.6 vs. 0.6, P = 0.944), smoking status (former 56.1% vs. 53.6%, P = 0.668), distance away from outpatient center (8.2 mi vs. 8.4 mi, P = 0.249), and had similar Connecticut state ADIs (2021 high-disadvantage: 35.4% vs. 33.3%, P = 0.549). Patients participating in the SET program were more likely to be male (78.8% vs. 56.0%, P = 0.003). Top self-reported barriers for patients who declined participation included transportation/distance (39.3%), preference for independent walking (56.0%), inability to commit to 3 sessions per week (52.4%), and lack of interest (20.2%). In addition, a higher proportion of patients who declined participation identified severe barriers of preference for independent walking (39.3% vs. 1.5%, P < 0.001), inability to commit to 3 sessions per week (26.2% vs. 3.0% P < 0.001), transportation/distance issues (23.8% vs. 7.6% P = 0.008), and cost (27.4% vs. 9.1%, P = 0.005) as significant barriers for participation in SET. CONCLUSIONS: Patients who declined participation in SET for PAD had similar disease status and access to care than participating counterparts. Top reported barriers to enrollment include a preference for independent walking, transportation/distance, commitment to 3x/week program, and cost, which highlight areas of focus for equitable access to these limb-saving services.

Rectus Sheath Block Improves Patient Recovery Following Open Aortic Surgery.

BACKGROUND: Postoperative pain management remains a barrier to recovery following aortic surgery. Although epidural catheters help in adjunctive pain management, less is known about the use of rectus sheath blocks. We compared patient recovery following open abdominal aortic surgery (OAS) with and without adjunctive rectus block. METHODS: Adult patients undergoing open abdominal aortic aneurysm repair and aortobifemoral or aortoiliac bypass for occlusive disease were identified and stratified by use of general anesthesia alone (GA) versus adjunctive use of a rectus sheath block (GA + RB). A small number of patients with GA and concomitant epidural analgesia, along with patients that had retroperitoneal repairs, were not included in further analysis. Outcomes included time to extubation, intraoperative and postoperative morphine milligram equivalents (MME) utilization, length of stay, discharge MME, and postoperative complications. Categorial data were compared with Person Chi-Square tests or Fisher's exact tests. Continuous data were tested with independent t-tests or Mann-Whitney U-tests. RESULTS: From January 2017 to April 2022, there were 106 patients who underwent open aortic surgery, 55 patients with GA alone, 39 with GA + RB, and 12 patients who had a GA with concomitant epidural analgesia. Between GA and GA + RB, patients were comparable in both groups in terms of age, BMI (body mass index), smoking history, hypertension, diabetes, CAD (coronary artery disease), COPD (chronic obstructive pulmonary disease), and ASA (American Society of Anesthesiologists) class and prior opioid use. Patients with GA + RB were more likely to have scheduled elective procedures (80% GA cohort vs. 94.9% RB, P = 0.040), and a lower incidence of retroperitoneal exposure (14.5% GA cohort vs. 0% RB, P = 0.019). Patients with GA + RB had shorter time to extubation than GA (84.6% < 12 hr vs. 44.4%, P < 0.001), greater rate of procedural ketamine usage (GA + RB: 61.5% vs. GA: 40.0%, P = 0.049), lower MME at first postoperative day (median MME GA + RB: 25.0 vs. GA: 67.5, P = 0.002), lower discharge MME (median MME GA + RB: 142.5 vs. GA: 225.0, P = 0.036), and overall shorter length of stay (median stay GA + RB: 5 vs. GA: 6 days, P = 0.006). Postoperative complications were similar between groups. Similar findings were found in the comparison between elective-only GA and GA + RB patients and after exclusion of patients who only had a single shot of regional anesthesia. CONCLUSIONS: Patients that receive adjunctive rectus sheath blocks for pain control following OAS utilize fewer opioid medications during hospital stay and at discharge. Rectus sheath blocks represent an alternative option to other periprocedural analgesia following open aortic surgery.

Modified Docetaxel, Cisplatin, and Fluorouracil (mDCF) as a Neoadjuvant Chemotherapy for Non-metastatic Esophageal Cancer (nMEC).

Objective: Perioperative chemotherapy can potentially downstage esophageal cancer, reducing the risk of early systemic dissemination. One recommended neoadjuvant regimen for managing gastroesophageal junction and esophageal cancer is docetaxel, cisplatin, and 5-fluorouracil (DCF). To address the high toxicity profile of DCF, modifications in dosages and treatment intervals have been studied. We integrated a modified DCF regimen (mDCF) into a multimodal treatment approach for non-metastatic esophageal cancer (nMEC). Retrospectively, we sought to describe our community experience of administrating neoadjuvant mDCF to patients with nMEC.Design: Patients diagnosed with nMEC between August 2008 and November 2017 and prescribed mDCF were identified for retrospective review. Outcomes of interest included disease-free survival (DFS), overall survival (OS), and hematologic toxicities. Analyses were performed using SAS 9.4.Results: Thirty patients met inclusion criteria with a median age of 64.9 years; 90% were male. The 2-year and 5-year DFS was 60.8% and 41.7%, respectively, for adenocarcinoma and 71.4% and 71.4% for squamous cell carcinoma (SCC). The 2-year and 5-year OS was 64.9% and 44.5%, respectively, for adenocarcinoma and 71.4% and 71.4% for SCC. Both DFS and OS decreased with increasing disease stage, histology (adenocarcinoma versus squamous), esophageal compared to esophagogastric-junction involvement, and without surgical intervention. Frequent toxicity grades for leukopenia and thrombocytopenia were Grades I and II.Conclusion: Using an mDCF regimen in combination with chemoradiation +/- surgical resection in a community setting appears to have an acceptable toxicity profile as well as DFS and OS outcomes compared to chemotherapeutic regimens reported in other similar studies.

Depression Outcomes From a Fully Integrated Obstetric Mental Health Clinic: A 10-Year Examination.

BACKGROUND: A fully integrated Obstetric Mental Health Clinic (OBMHC) was established in 2007 in the rural northwest United States to address perinatal depression. AIMS: The purpose of this mixed methods study was to examine depression outcomes in women receiving outpatient psychiatric services between 2007 and 2017 at a fully integrated OBMHC and to explore patient and obstetric team perceptions of OBMHC experiences. METHOD: A retrospective database study was employed; depression was measured at baseline and follow-up visits using the Edinburgh Postnatal Depression Scale. Descriptive statistics, regression models, and trend analysis were employed to determine effectiveness. A subset of patients participated in telephone interviews; the obstetric team was surveyed regarding perceptions of the service. RESULTS: The sample included 192 women (195 pregnancies). Approximately 72% experienced less depression by the first follow-up visit. Patients taking three or more psychiatric medications attended more OBMHC visits. Trend analysis indicated that women with the highest levels of depression had the best response to the intervention. Three qualitative themes emerged: Safe Place, Mental/Emotional Stability, and Integrated Personalized Approach. Obstetric team members (n = 11) perceived the clinic to be helpful and noted improved access to mental health care. CONCLUSION: OBMHCs can be effective when psychiatric nurses are embedded within an outpatient obstetric service. Improved access, timely services, and patient reassurance can lead to an improved pregnancy experience and reduced depressive symptoms. The longevity of this clinic's experience serves as a role model for other centers to replicate this successful integrated model of care.

Association of a Novel Electronic Form for Preoperative Cardiac Risk Assessment With Reduction in Cardiac Consultations and Testing: Retrospective Cohort Study.

BACKGROUND: Preoperative cardiac risk assessment is an integral part of preoperative evaluation; however, there is significant variation among providers, leading to inappropriate referrals for cardiology consultation or excessive low-value cardiac testing. We implemented a novel electronic medical record (EMR) form in our preoperative clinics to decrease variation. OBJECTIVE: This study aimed to investigate the impact of the EMR form on the preoperative utilization of cardiology consultation and cardiac diagnostic testing (echocardiograms, stress tests, and cardiac catheterization) and evaluate postoperative outcomes. METHODS: A retrospective cohort study was conducted. Patients who underwent outpatient preoperative evaluation prior to an elective surgery over 2 years were divided into 2 cohorts: from July 1, 2021, to June 30, 2022 (pre-EMR form implementation), and from July 1, 2022, to June 30, 2023 (post-EMR form implementation). Demographics, comorbidities, resource utilization, and surgical characteristics were analyzed. Propensity score matching was used to adjust for differences between the 2 cohorts. The primary outcomes were the utilization of preoperative cardiology consultation, cardiac testing, and 30-day postoperative major adverse cardiac events (MACE). RESULTS: A total of 25,484 patients met the inclusion criteria. Propensity score matching yielded 11,645 well-matched pairs. The post-EMR form, matched cohort had lower cardiology consultation (pre-EMR form: n=2698, 23.2% vs post-EMR form: n=2088, 17.9%; P<.001) and echocardiogram (pre-EMR form: n=808, 6.9% vs post-EMR form: n=591, 5.1%; P<.001) utilization. There were no significant differences in the 30-day postoperative outcomes, including MACE (all P>.05). While patients with "possible indications" for cardiology consultation had higher MACE rates, the consultations did not reduce MACE risk. Most algorithm end points, except for active cardiac conditions, had MACE rates <1%. CONCLUSIONS: In this cohort study, preoperative cardiac risk assessment using a novel EMR form was associated with a significant decrease in cardiology consultation and testing utilization, with no adverse impact on postoperative outcomes. Adopting this approach may assist perioperative medicine clinicians and anesthesiologists in efficiently decreasing unnecessary preoperative resource utilization without compromising patient safety or quality of care.

Continuous Serratus Anterior Versus Erector Spinae Plane Block Catheters for Postoperative Pain Management Following Video-Assisted Thoracoscopic Surgery: A Retrospective Study.

INTRODUCTION: Optimal pain management following video-assisted thoracoscopic surgery (VATS) is key to promoting efficient recovery while minimizing the incidence of postoperative complications. Regional anesthesia can help achieve greater pain control, fostering enhanced recovery and increased patient satisfaction, though debate remains over the most effective technique for VATS. This study sought to compare the analgesic efficacy of two continuous regional anesthetic techniques commonly used for VATS, the serratus anterior plane block (SAPB or CSAPB) and the erector spinae plane block (ESPB or CESPB). This study also sought to identify the clinical benefits of regional anesthesia (CSAPB or CESPB) versus no regional anesthesia in the setting of VATS. METHODS: A retrospective study was conducted, including 397 adult patients who underwent VATS and received multimodal analgesia. Postoperative outcomes were compared among patients who received CSAPB versus those who received CESPB; these outcomes were also compared between patients who received either regional anesthesia technique (CSAPB or CESPB, block group) and patients who did not receive regional anesthesia (non-block group). Co-primary outcomes included opioid consumption during hospital admission (presented as morphine milligram equivalents) and pain (minimum, maximum, and average numeric pain scale scores) in the first 72 postoperative hours. Secondary postoperative outcomes included post-anesthesia care unit (PACU) length of stay, time from procedure end to discharge, time to first opioid medication, ambulation distance on day one, medication use, and incidence of surgical or block-related complications. All data were retrospectively obtained from patients' electronic medical records. RESULTS: Comparing regional anesthesia techniques, patients who received CESPB reported lower pain with activity postoperatively than patients who received CSAPB (3.6 vs. 4.2, p=0.009). There were no other significant differences in postoperative outcomes between these groups. Comparing the block and non-block groups, the block group exhibited a higher overall comorbidity burden than the non-block group (p=0.001). Even so, the block group reported less postoperative pain at rest and with activity than the non-block group (mean: 3.6 vs. 4.1, p=0.012; mean 3.8 vs. 4.4, p=0.012). PACU stay and time to discharge were longer in the block group than non-block group (3.3 vs. 2.6 hours, p=0.004 and 3.1 vs. 2.9 days, p=0.012, respectively). However, the block group ambulated a significantly longer distance than the non-block group on the first postoperative day (median: 181.1 m vs. 73.2 m, p<0.001). The block group more often received acetaminophen and/or aspirin and gabapentinoids than the non-block group (94.5% vs. 75.0%, p<0.001 and 84.8% vs. 62.0%, p<0.001, respectively). CONCLUSION: Both CESPB and CSAPB are effective regional anesthesia techniques for VATS postoperative pain management with clear clinical benefits over no regional anesthesia. A direct comparison of the analgesic efficacy of CESPB versus CSAPB indicated that CESPB is more effective than CSAPB in terms of pain control. These findings are consistent with existing literature and most recent practice recommendations.

Multimodal approach utilising a weight management programme prior to bariatric surgery in patients with BMI ≥50 kg/m2: A propensity score matching retrospective cohort study.

We evaluated preoperative weight loss and days from initial consult to surgery in patients with BMI ≥50 kg/m2 who were and were not enrolled in medical weight management (MWM) prior to laparoscopic sleeve gastrectomy. We retrospectively identified patients with BMI ≥50 kg/m2 who had primary sleeve gastrectomy between 2014 and 2019 at two bariatric surgery centres in our healthcare system. Patients presenting after 2017 that received preoperative MWM (n = 28) were compared to a historical cohort of non-MWM patients (n = 118) presenting prior to programme initiation in 2017 on preoperative percent total body weight loss (%TBWL) and days from initial consult to surgery. A total of 151 patients (MWM, 33; non-MWM, 118) met inclusion criteria. BMI was significantly greater in MWM versus non-MWM (p = .018). After propensity score matching, median BMI at initial consult in non-MWM versus MWM no longer differed (p = .922) neither were differences observed on the basis of weight, age, sex, race or ethnicity. After PSM, MWM had significantly lower BMI at surgery (p = .018), lost significantly more weight from consult to surgery (p < .001) and achieved significantly greater median %TBWL from consult to surgery (p < .001). We noted no difference between groups on 6-month weight loss (p = .533). Days from initial consult to surgery did not differ between groups (p < .863). A preoperative MWM programme integrated into multimodal treatment for obesity in patients with a BMI ≥50 kg/m2 resulted in clinically significant weight loss without prolonging time to surgery.

Incidence of Hiatal Hernia Repair During Primary Bariatric Surgery Conversion: an Analysis of the 2020 MBSAQIP Database.

The rate of hiatal hernia (HH) repair during conversion bariatric surgery is largely unknown. We sought to determine this rate in 12,788 patients undergoing conversion surgery using the 2020 participant use file of the MBSAQIP database. Concurrent HH repair was performed in 24.1% of conversion cases; most commonly during SG to RYGB (33.1%), followed by AGB to SG conversion (20.2%). The remaining conversion pathways had a repair rate around 13%. Only 12.1% of HH repairs were performed using a mesh. GERD was the primary indication for conversion in 65% of the SG to RYGB cases. A much higher proportion of patients with concomitant HH repair reported GERD as the main reason for conversion than those without a HH repair (44.5% vs. 23.7%; p<0.001).

Is oestrogen receptor-negative/progesterone receptor-positive (ER-/PR+) a real pathological entity?

BACKGROUND: The existence of oestrogen receptor-negative (ER-)/progesterone receptor-positive (PR+) breast cancer continues to be an area of controversy amongst oncologists and pathologists. METHODS: To re-evaluate breast cancers originally classified as ER-/PR+ via Oncotype DX® assay and compare molecular phenotype with Recurrence Score® (RS) result, clinicopathologic features and clinical outcomes were retrospectively obtained from electronic health records between January 1998 and June 2005. Archived formalin-fixed, paraffin-embedded (FFPE) tumour specimens were tested for the expression of ER, PR and human-epidermal-growth-factor-2. The number of positive ER-/PR+ samples confirmed by transcriptional analysis was the primary outcome of interest with event-free and overall survival as secondary outcomes. Biopsies from 26 patients underwent Oncotype DX testing and analysis. RESULTS: Approximately 60% were middle-aged (40-50 years old) women, and 84.6% had invasive ductal carcinoma. Based on the Oncotype DX assay, approximately 65% (N = 17) had ER+/PR+ status; 23% (N = 6) had ER-/PR- status; and 12% had a single hormone positive receptor (1 ER-/PR+, 2 ER+/PR-) status. Almost one-quarter of patients were stratified into the low-RS (<18) or intermediate-RS (18-30) results, and half of the patients had a high-RS (>30) result. CONCLUSION: Our findings suggest the ER-/PR+ subtype is not a reproducible entity and emphasises the value of retesting this subtype via molecular methods for appropriate treatment selection and patient outcomes. Multigene assay analysis may serve as a second-line or confirming tool for clinical determination of ER/PR phenotype in breast cancer patients for targeted therapies.

Randomized Trial of VasoStat Versus TR Band Following Radial Artery Access for Catheterization Procedures.

PURPOSE: VasoStat (VS; Forge Medical) is a recently developed radial artery compression device (RCD) producing focused puncture-site pressure. We compared time to hemostasis and patient experience with VS vs balloon compression with the TR Band (Terumo) in a randomized, prospective trial among subjects undergoing radial catheterization procedures with same-day discharge. METHODS: Forty subjects without prior radial access undergoing elective coronary and/or endovascular diagnostic or interventional procedures were randomized to VS or TR Band. Primary outcome was time to hemostasis enabling RCD removal. Secondary outcomes included patient satisfaction measuring subject-reported domains of pain, paresthesia, and swelling, number of device manipulations, and radial patency at follow-up duplex assessment. Hand perfusion index (PI) was also measured prior to radial access, during RCD use, during RCD use with ulnar compression, and after 30 days. RESULTS: VS reduced time to complete hemostasis by 54 ± 20 minutes compared with TR Band (P=.01). Time from RCD application to discharge trended shorter among the VasoStat patients vs TR Band patients (209 ± 13 minutes vs 254 ± 22 minutes, respectively; P=.09). VS required fewer RCD manipulations (P=.04). Mean patient discomfort score was 2.7 with VS and 6.1 with TR (P=.04). Change from baseline in hand PI was similar at all time points. After 30 days, ultrasound detected no radial artery occlusion and no difference in radial artery peak systolic velocities (57 cm/s with VS vs 50 cm/s with TR; P=.85). CONCLUSION: Both RCDs achieved hemostasis enabling same-day discharge. VS had significantly shorter time to hemostasis with fewer device manipulations and increased patient-reported comfort.

Frequency of Parathyroid Hormone Assessment in the Evaluation of Hypercalcemia. A Comparison Between Patients With and Without a History of Malignancy in a 20-year Dataset of 20,954 Patients.

BACKGROUND: The purpose of this study was to evaluate whether a prior diagnosis of malignancy affected the assessment of parathyroid hormone (PTH) in hypercalcemic patients and whether the rate of this assessment changed over time. METHODS: A retrospective cohort study was designed that included adult patients with hypercalcemia with and without a history of malignancy between January 1, 2000 and December 31, 2019 in the Marshfield Clinic Health System (MCHS). The overall and annual rates of PTH assessment in each group was determined. In patients with a PTH assessment, duration of time and number of elevated serum calcium levels between the first documentation of hypercalcemia and the assessment of PTH were recorded, as was the degree of hypercalcemia. RESULTS: Approximately a quarter (23%) of the patients in each group had a PTH assessment. The rate of PTH assessment initially increased over time but later declined significantly. Although a more severe degree of hypercalcemia predicted a greater probability of PTH assessment, the rate of assessment declined with all degrees of hypercalcemia in the last 5 years. While most patients who had a PTH assessed did so within a few months of the first documentation of hypercalcemia, less than half (40%) had a delay of more than 2 years before a PTH level was drawn. CONCLUSION: This lack of appropriate and timely assessment may have significant health consequences in both groups of patients. Better education of providers about the appropriate and timely assessment of PTH in the evaluation of hypercalcemia is urgently needed.

Evaluation of Diagnostic Workup and Etiology of Hypercalcemia of Malignancy in a Cohort of 167 551 Patients Over 20 Years.

CONTEXT: Hypercalcemia of malignancy (HCM) has not been studied in a fashion to determine all possible mechanisms of hypercalcemia in any given patient. OBJECTIVE: The 2 objectives were to assess the completeness of evaluation and to determine the distribution of etiologies of HCM in a contemporary cohort of patients. METHODS: A retrospective analysis was performed of patients with cancer who developed hypercalcemia over 20 years at a single health system. Laboratory data were electronically captured from medical records to identify cases of parathyroid hormone (PTH)-independent hypercalcemia. The records were then manually reviewed to confirm the diagnosis of HCM, document the extent of evaluation, and determine underlying etiology(ies) of HCM in each patient. RESULTS: The initial data set included 167 551 adult patients with malignancy, of which 11 589 developed hypercalcemia. Of these, only a quarter (25.4%) had assessment of PTH with a third of the latter (30.9%) indicating PTH-independent hypercalcemia. Of those with PTH-independent hypercalcemia, a third (31.6%) had assessment of PTH-related peptide (PTHrP) and/or 1,25-dihydroxy (1,25-OH) vitamin D and constituted the 153 cases of HCM examined in this study. Eighty-three of these patients had an incomplete evaluation of their HCM. The distribution of etiologies of HCM was therefore determined from the remaining 70 patients who had assessment of all 3 possible etiologies (PTHrP, 1,25-OH vitamin D, and skeletal imaging) and was as follows: PTHrP, 27%; osteolytic metastases, 50%; and 1,25-OH vitamin D, 39%, with combinations of etiologies being common (approximately 20%). CONCLUSION: HCM is incompletely evaluated in many patients. The distribution of etiologies of HCM in this report differs significantly from the previous literature, warranting further study to determine whether its causes have indeed changed over time.

A review of breast cancer pathology reports in Nigeria.

BACKGROUND: Diagnosis and treatment of cancer rely heavily on imaging, histopathology and molecular information. Incomplete or missing tumour information can hinder the delivery of high-quality care in oncology practice, especially in resource-limited countries. To evaluate the completeness of histopathology reporting in a real-world setting and identify areas for future cancer care delivery research efforts, we retrospectively analysed reports from patients diagnosed with breast cancer who received care at a high-volume oncology department at a hospital in Lagos, Nigeria. METHODS: Demographic, institutional and histopathology characteristics were retrospectively obtained from 1,001 patient records from 2007 to 2016. Completeness was defined as reporting five tumour features (tumour histology, tumour grade, laterality, oestrogen receptor (ER) or progesterone receptor (PR) and human epidermal growth factor receptor 2 (HER2)) for biopsy specimens and seven tumour features (tumour size, tumour histology, tumour grade, laterality, ER/PR, HER2 and lymph node involvement) for surgical specimens. RESULTS: The mean age of patients was 48.6 ± 11.7 years with a predominantly female population (99.3%). A majority of pathologic reports were produced after 2011, and two-thirds of the reports originated from centres or labs within Lagos, Nigeria (67.7%). Most reports documented primary site (98.0%) and specimen type (85.0%) while other characteristics were less often recorded. This led to substantial variation in reporting between biopsy (13.4%) and surgical (6.1%) specimens for an overall low pathology report completeness <10%. CONCLUSION: The majority of patient records analysed lacked complete documentation of breast cancer histopathological characteristics commonly used in oncology practice. Our study highlights a need to identify and address the contributing factors for incomplete histopathological reporting in Nigeria and will guide future clinical programmatic developments.

Cost-effectiveness of Dabigatran Compared With Rivaroxaban for Prevention of Stroke and Systemic Embolism in Patients With Atrial Fibrillation in China.

PURPOSE: In China, dabigatran and rivaroxaban are the only approved non-vitamin K antagonist oral anticoagulants for the treatment of atrial fibrillation (AF). The goal of this article was to assess the cost-effectiveness of dabigatran versus rivaroxaban for the prevention of stroke and systemic embolism in Chinese patients with AF from the perspective of the Chinese health care system. METHODS: A Markov model was constructed to estimate the cost-effectiveness of dabigatran versus rivaroxaban. Clinical events were modeled for a lifetime horizon, based on clinical efficacy data from indirect treatment comparisons. The weighted average of the most recent prices of these 2 drugs was used as the drug acquisition cost. Other costs, including follow-up costs and event costs, were collected by using a survey from a panel of local experts. Utility inputs (health state utilities, clinical event disutilities, and event history utility) were obtained from published literature. Sensitivity analyses that included scenario analyses and a probabilistic sensitivity analysis were conducted to examine the robustness of the economic model. FINDINGS: Over a lifetime, patients treated with dabigatran experienced fewer ischemic strokes (2.14 dabigatran vs 2.61 rivaroxaban) and fewer intracranial hemorrhage (0.48 vs 0.94) per 100 patient-years. In the base case analysis, dabigatran had an incremental cost of ¥28,128 but with higher life years (10.38 vs 10.14) and quality-adjusted life years (QALYs) (7.95 vs 7.70). The resulting incremental cost-effectiveness ratio of ¥112,910 per QALY gained and net monetary benefit of ¥12,214 versus rivaroxaban showed that dabigatran was a cost-effective alternative to rivaroxaban. Extensive sensitivity analyses indicated that the results were robust over a wide range of inputs. The probabilistic sensitivity analysis indicated that dabigatran was cost-effective in 84.2% of the 10,000 Monte Carlo simulations compared with rivaroxaban. IMPLICATIONS: Dabigatran reduced the occurrence of clinical events and increased QALYs compared with rivaroxaban. The use of dabigatran for the prevention of stroke and systemic embolism is a cost-effective option compared with rivaroxaban among patients with AF in China.

Assessment of sexually transmitted disease/HIV risk among young African Americans: comparison of self-perceived and epidemiological risks utilizing ecodevelopmental theory.

Background: Recent advances in understanding the developmental processes associated with adolescents warrant new thinking and systematic application of key concepts of risk and protective processes. This study examined the association between epidemiological and self-perceived risks of contracting sexually transmitted diseases (STDs)/HIV among young African Americans (AAs) and the multilevel factors identified using ecodevelopmental theory. Methods: A retrospective cross-sectional study was conducted on wave 1 data from the National Longitudinal Study of Adolescent Health comprising 1,619 AA youth aged 14-18 years. Epidemiological and self-perceived HIV-risk indices were developed and their associations with ecodevelopmental system parameters evaluated. Results: Significant discordance (P<0.0001) in the youths' self-perceived risk and epidemiological risk (the "gold standard") was recorded with Cohen's k-coefficient of 0.144 (95% CI 0.104-0.193). Adolescents who felt like talking to their mother had no trouble getting along with schoolteachers, perceived that teachers treated student fairly, experienced mother's disapproval of their sexual debut, and had close friends who knew how to use condoms correctly, were positively related to low epidemiological risk of contracting STDs/HIV. Being older, male, and a mother's positive attitude toward their adolescent's use of birth control (in exosystem) were associated with high epidemiological risk of contracting STDs/HIV. Furthermore, poor connection with the mother (did not feel like talking to mother) and growing older were related to low accuracy of self-risk perception among AA youths. Conclusion: The findings demonstrate the strong need to align self-perceived risk with epidemiological risk of acquiring STDs/HIV using the key multilevel ecodevelopmental system factors identified. This will require changes in relevant social attitudes and norms associated with risk measurement, and allow for a rational basis for safe health practices and behaviors among AA youths.

Global Survey of the Roles, Satisfaction, and Barriers of Home Health Care Nurses on the Provision of Palliative Care.

Background: The World Health Assembly urges members to build palliative care (PC) capacity as an ethical imperative. Nurses provide PC services in a variety of settings, including the home and may be the only health care professional able to access some disparate populations. Identifying current nursing services, resources, and satisfaction and barriers to nursing practice are essential to build global PC capacity. Objective: To globally examine home health care nurses' practice, satisfaction, and barriers, regarding existing palliative home care provision. Design: Needs assessment survey. Setting/Subjects: Five hundred thirty-two home health care nurses in 29 countries. Measurements: A needs assessment, developed through literature review and cognitive interviewing. Results: Nurses from developing countries performed more duties compared with those from high-income countries, suggesting a lack of resources in developing countries. Significant barriers to providing home care exist: personnel shortages, lack of funding and policies, poor access to end-of-life or hospice services, and decreased community awareness of services provided. Respondents identified lack of time, funding, and coverages as primary educational barriers. In-person local meetings and online courses were suggested as strategies to promote learning. Conclusions: It is imperative that home health care nurses have adequate resources to build PC capacity globally, which is so desperately needed. Nurses must be up to date on current evidence and practice within an evidence-based PC framework. Health care policy to increase necessary resources and the development of a multifaceted intervention to facilitate education about PC is indicated to build global capacity.

The Stepped-Wedge Trial Design: Paving the Way for Cancer Care Delivery Research.

Cancer care delivery research (CCDR) is an emerging field that investigates ways to optimally provide care for patients within complex health-care systems. Novel research designs are essential to efficiently study CCDR research questions. A stepped-wedge trial (SWT) is one such pragmatic design and is similar to a parallel randomized controlled trial (RCT). An SWT design has several advantages. It can examine the clinical effectiveness of an intervention by using participants as the control group, address potential ethical issues, and extend time for trial implementation or policy changes with fewer resources than are used to conduct several RCTs. All participants eventually receive the intervention, which can make the trial more desirable for patient participation. This article aims to introduce and discuss the SWT study design and to encourage future application for CCDR and other oncology-related research.

HIV-related sexual decisions made by African-American adolescents living in different family structures: study from an ecodevelopmental perspective.

PURPOSE: The purpose of this study was to explore the association between the dynamics of family structure and sexual behaviors of African-American adolescents using the ecodevelopmental theory. METHODS: This study stratified data from 1,617 African-American adolescents of the Add Health Wave I respondents with an identified family composition. It examined the associations between family structure, parenting function, and adolescents' sexual decision-making: age of first sexual intercourse, sexual initiation before age 16, and using a condom during the first and last sexual intercourse. RESULTS: Emotional connection between parents and children (feeling more love from the father: ß=0.17, P=0.0312; feeling more love from the mother: ß=0.3314, P=0.0420) and mothers' less permissive attitude toward adolescents' sexual experience in their teens (ß=0.33, P=0.0466) are positively associated with late age of sexual initiation of adolescents living in two-parent households. School-level factors (ß=0.07, P=0.0008) and the adolescents' characteristics (being older: 0.42, P=0.0002; heterosexuality: ß=2.28, P=0.0091) are the factors most positively related to the age of sexual initiation for those living with a single parent. Immediate social determinants, other than family factors (such as land use of immediate area [rural]: ß=9.84, P<0.0001; the condition of living unit: ß=1.55, P=0.0011; and safety of neighborhood: ß=4.46, P=0.004), are related to late age of sexual initiation among those living with other relatives/alone. A higher tendency of condom use consistency was present in adolescents living with two parents compared to those living in other family structures. CONCLUSION: Less parent/child connection and parent/family influence were found in African-American adolescents living with other relatives or alone, suggesting that living with two residential parents plays an essential role in their late sexual initiation and could account for an important element to combat high HIV incidence of African-American adolescents.

Modeling ecodevelopmental context of sexually transmitted disease/HIV risk and protective behaviors among African-American adolescents.

Risk and protective processes are integrated developmental processes that directly or indirectly affect behavioral outcomes. A better understanding of these processes is needed, in order to gauge their contribution to sexual risk behaviors. This retrospective cross-sectional study modeled the ecodevelopmental chain of relationships to examine the social contexts of African-American (AA) adolescents associated with sexually transmitted disease (STD)- and HIV-risk behaviors. We used data from 1,619 AA adolescents with an average age of 16±1.8 years obtained from the first wave of the National Longitudinal Study of Adolescent Health for this study. Confirmatory factor analysis followed by structural equation modeling was conducted to identify the latent constructs that reflect the social-interactional components of the ecodevelopmental theory. Among contextual factors, findings indicated that a feeling of love from father, school, religion, and parent attitudes toward adolescent sexual behavior were all factors that played significant roles in the sexual behavior of AA adolescents. AA adolescents who reported feeling love from their father, feeling a strong negative attitude from their parents toward having sex at a very young age, and having a strong bond with school personnel were associated with better health statuses. The level of parents' involvement in their children's lives was reflected in the adolescents' feeling of love from parents and moderated by their socioeconomic status. Being male, attaining increased age, and being a sexual minority were associated with higher likelihood of exhibiting risky sexual behavior. In contrast, higher socioeconomic status and fathers' level of involvement were indirectly associated with reduced STD/HIV-related sexual risk behavior. In conclusion, our findings suggest that interventions aimed at maximal protection against STD/HIV-related risk behavior among AA adolescents should adopt both self- and context-based strategies that promote positive functioning in the family, school, and peer microsystems.
