RESUMEN

Health-related quality of life (HRQoL) is an important outcome for patients with sickle cell disease (SCD). It is often poor compared with other chronic medical conditions or measured as a multidomain disease-specific construct. We previously reported outcomes in the Start Healing in Patients with Hydroxyurea (SHIP-HU) randomized controlled trial in adolescents and adults with SCD at six clinical sites. Besides the primary outcomes, we also measured HRQoL as a secondary outcome. Patients in the intervention arm were each assigned community health workers (CHWs) who provided case management services. CHW services were independent of medical management, and medical managers were blinded to the study arm. Patients in the control arm received only standard of care. We hypothesized that having a CHW would improve HRQoL in patients enrolled in SHIP-HU. We did not find significant differences between domains of HRQoL in the two study arms. Possible explanations include selection bias of enrolled versus unenrolled patients, selection bias of sites, medical providers and medical management, enforced blinding, and a lack of cooperation between medical managers and CHWs. The importance of CHWs and HRQoL is nonetheless recognized based on the literature. Future interventions on HRQoL in SCD should consider alternative study designs and multimodal interventions.

RESUMEN

Hydroxyurea (hydroxycarbamide) (HU) for sickle cell anaemia (SCA) is underutilised. Case management is an evidence-based health management strategy and in this regard patient navigators (PNs) may provide case management for SCA. We hypothesised that HU-eligible patients exposed to PNs would have improved indicators of starting HU and HU adherence. We randomised 224 HU-eligible SCA adults into the Start Healing in Patients with Hydroxyurea (SHIP-HU) Trial. All patients received care from trained physicians using standardised HU prescribing protocols. Patients in the Experimental arm received case management and education from PNs through multiple contacts. All other patients were regarded as the Control arm and received specialty care alone. Study physicians were blinded to the study arms and did not interact with PNs. At baseline, 6 and 12 months we assessed and compared laboratory parameters and HU adherence indicators. Experimental patients had higher 6-month mean fetal haemoglobin (HbF) levels than controls. But at 12 months, mean HbF was similar, as were white blood cell count, absolute neutrophil count, total haemoglobin, platelet count and mean corpuscular volume. At 12 months there were fewer experimental patients missing HU doses than controls (mean 1·8 vs. 4·5, P = 0·0098), and more recent HU prescriptions filled than for controls (mean 53·8 vs. 92 days, median 27·5 vs. 62 days, P = 0·0082). Mean HU doses were largely similar. We detected behavioural improvements in HU adherence but no haematological improvements by adding PNs to specialty care.

RESUMEN

Disease-specific stress can partly explain Sickle Cell Disease (SCD) healthcare utilization. We developed and validated two measures of adult SCD-specific stress for research and clinical care. A large cohort of adults with SCD completed both the 3-item Likert-scale adapted from a previous disease stress measure and a 10-item Likert-scale questionnaire drafted specifically to measure SCD stress. They concurrently completed a psychosocial and health-related quality of life scale battery, then subsequently daily pain diaries. Diaires measured: daily intensity, distress and interference of pain; self-defined vaso-occlusive crises (VOC), opioid use, and types of healthcare utilization for up to 24 weeks. Analyses tested Cronbach's alpha, correlation of the three-item and 10-item stress scales with the concurrent battery, with percentages of pain days, VOC days, opioid use days, and healthcare utilization days, and correlation of baseline stress and 6-month stress for the 10-item scale. Cronbach's alpha was high for both the 3-item (0.73) and 10-item (0.83) SCD stress scales, test-retest correlation of 0.55, expected correlation with the concurrent battery, and correlation with diary-measured healthcare utilization over 6 months. The correlations with the 3-item scale were stronger, but only statistically significant for depression-anxiety. The correlation between the two stress scales was 0.59. Both the 3-item and the 10-item stress scales exhibited good face, construct, concurrent, and predictive validity as well as moderate test-retest reliability. Further scale validation should determine population norms and response to interventions.

RESUMEN

A lack of adult sickle cell providers has long been blamed for poor satisfaction and access to specialty care for adults with sickle cell disease (SCD). We were interested in comparing how adolescent and adult patients already in established SCD centers perceived access and quality of care. Hydroxyurea-eligible patients aged 15 years and older were enrolled in the Start Healing in Patients with Hydroxyurea trial, which required them to be affiliated with a SCD specialist. Patients were seen in one of three adult-oriented specialty clinic sites or one of three pediatric-oriented sites. At baseline, patients completed the Adult Sickle Cell Quality of Life Measurement Information System measure as part of a survey battery. Patients treated at adult clinic sites reported being less able to get timely ambulatory appointments (p = .004). They reported emergency department (ED) wait times of >1 h far more often (47.7 vs. 19.3%, p = .0048). They reported less overall satisfaction with care (7.47 vs. 8.77, p < .0001), and less satisfaction with care in the ED (2.88 vs. 3.4, p = .0068. Ambulatory satisfaction was no different between pediatric site versus adult site patients. Poorer systems of care appeared to underlie reported differences, rather than differences in biopsychosocial determinants. Even among specialty-care-affiliated SCD patients, those seen in adult clinics reported worse access to care and lower satisfaction with care than patients seen in pediatric clinics. In addition to increasing the number of adult SCD providers and better preparing pediatric SCD patients to transfer to adult programs, SCD clinical caregivers must also improve aspects of adult care quality to meet reasonable patient expectations of timeliness and interpersonal aspects of care quality.

RESUMEN

In the medical literature, there has been an increased interest in evaluating association between exposure and outcomes using nonrandomized observational studies. However, because assignments to exposure are not random in observational studies, comparisons of outcomes between exposed and nonexposed subjects must account for the effect of confounders. Propensity score methods have been widely used to control for confounding, when estimating exposure effect. Previous studies have shown that conditioning on the propensity score results in biased estimation of conditional odds ratio and hazard ratio. However, research is lacking on the performance of propensity score methods for covariate adjustment when estimating the area under the ROC curve (AUC). In this paper, AUC is proposed as measure of effect when outcomes are continuous. The AUC is interpreted as the probability that a randomly selected nonexposed subject has a better response than a randomly selected exposed subject. A series of simulations has been conducted to examine the performance of propensity score methods when association between exposure and outcomes is quantified by AUC; this includes determining the optimal choice of variables for the propensity score models. Additionally, the propensity score approach is compared with that of the conventional regression approach to adjust for covariates with the AUC. The choice of the best estimator depends on bias, relative bias, and root mean squared error. Finally, an example looking at the relationship of depression/anxiety and pain intensity in people with sickle cell disease is used to illustrate the estimation of the adjusted AUC using the proposed approaches.

RESUMEN

Cost and burden of diagnostic testing may be reduced if fewer tests can be applied. Sequential testing involves selecting a sequence of tests, but only administering subsequent tests dependent on results of previous tests. This research provides guidance to choosing between single tests or the believe the positive (BP) and believe the negative (BN) sequential testing strategies, using accuracy (as measured by the Youden Index) as the primary determinant. Approximately 75% of the parameter combinations examined resulted in either BP or BN being recommended based on a higher accuracy at the optimal point. In about half of the scenarios BP was preferred, and the other half, BN, with the choice often a function of the value of the ratio of standard deviations of those without and with disease (b). Large values of b for the first test of the sequence tended to be associated with preference for BN as opposed to BP, while small values of b appear to favor BP. When there was no preference between sequences and/or single tests based on the Youden Index, cost of the sequence was considered. In this case, disease prevalence plays a large role in the selection of strategies, with lower values favoring BN and sometimes higher values favoring BP. The cost threshold for the sequential strategy to be preferred over a single, more accurate test, was often quite high. It appears that while sequential strategies most often increase diagnostic accuracy over a single test, sequential strategies are not always preferred.

RESUMEN

Background: Pain diary assessment in sickle cell disease (SCD) may be expensive and impose a high respondent burden. Objective: To report whether intermittent assessment could substitute for continuous daily pain assessment in SCD. Design: Prospective cohort study. Setting: Academic and community practices in Virginia. Patients. A total of 125 SCD patients age 16 years or older in the Pain in Sickle Cell Epidemiology Study. Measurements. Using pain measures that summarized all diaries as the gold standard, we tested the statistical equivalence of four alternative strategies that summarized diaries only from the week prior or the month prior to study completion; one week per month; or one day per week (random day). Summary measures included percent pain days, percent crisis days (self-defined), mean pain (0-9 Likert scale) on all days, and mean pain on pain days. Equivalence tests included comparisons of means, regression intercepts, and slopes, as well as measurement of R2. Results: Compared with the gold standard, the one-day-per-week and one-week-per-month strategies yielded statistically equivalent means of six summary pain measures, and the week prior and month prior yielded equivalent means as some of the measures. Regression showed statistically equivalent slopes and intercepts to the gold standard using one-day-per-week and one-week-per-month strategies for percent pain days and percent crisis days, but almost no other equivalence. R2 values ranged from 0.64 to 0.989. Conclusions: It is possible to simulate five- to six-month daily assessment of pain in SCD. Either one-day-per-week or one-week-per-month assessment yields an equivalent mean and fair regression equivalence.

RESUMEN

BACKGROUND: Emergency Department (ED) revisits have often been used as an indicator of medical care quality. This study aimed to quantify the frequency of ED revisits within 72 h of discharge and identify its factors among children with chronic diseases. METHODS: We designed a retrospective cohort study of children with at least one chronic disease who were also under 18 years of age and had attended and were discharged from the ED at King Abdullah Specialist Children's Hospital (KASCH-RD), Riyadh, Saudi Arabia between April 19, 2015 and July 29, 2017. The outcome measure was the frequency of ED revisits during a period of 72 h after discharge. RESULTS: The study included 11,057 ED discharges of children with at least one chronic disease. Their revisit rate was 1211 (11%), with 83 (6.9%) having had a second ED revisit within 72 h of ED discharge. According to ICD-10 codes, the most common causes of ED revisits were respiratory, digestive, genitourinary, symptoms, and external causes. Factors of frequent ED revisits within 72 h were young age, institutional health insurance coverage, year of new health information system (2015), external causes, and genitourinary. CONCLUSION: The rate of 72-h ED revisits after discharge of children with chronic diseases treated at KASCH-RD was relatively high, and was associated with young age, institutional health insurance coverage, year of a new health information system implementation, and external causes of ED visit. These study findings amplify the need for intervention to reduce the rate of early ED revisits among children with chronic diseases.

RESUMEN

BACKGROUND: Individuals living with sickle cell disease (SCD) have significantly increased emergency department (ED) use compared to the general population. In Saudi Arabia, health care is free for all individuals and therefore has no bearing on increased ED visits. However, little is known about the relationship between quality of life (QoL) and frequency of acute care utilization in this patient population. METHODS: A cross-sectional study was conducted on 366 patients with SCD who attended the outpatient department at King Fahad Hospital, Hofuf, Saudi Arabia. Data were collected through self-administered surveys, which included: demographics, SCD-related ED visits, clinical issues, and QoL levels. We assessed the ED use by asking for the number of SCD-related ED visits within a 6-month period. RESULTS: The self-report survey of ED visits was completed by 308 SCD patients. The median number of SCD-related ED visits within a 6-month time period (IQR) was four (2-7 visits). According to the unadjusted negative binomial model, the rate of SCD-related ED visits increased by (46, 39.3, 40, and 53.5 %) for patients with fever, skin redness with itching, swelling, and blood transfusion, respectively. Poor QoL tends to increase the rate of SCD-related ED visits. Well education and poor general health positively influenced the rate of SCD-related ED visits. Well education tends to increase the rate of SCD-related ED visits by 50.2 %. The rate of SCD-related ED visits decreased by 1.4 % for every point increase in general health. CONCLUSION: Saudi patients with sickle cell disease reported a wide range of SCD-related ED visits. It was estimated that six of 10 SCD patients had at least three ED visits within a 6-month period. Well education and poor general health resulted in an increase in the rate of SCD-related ED visits.

RESUMEN

BACKGROUND: There is a lack of research concerning health-related quality of life (HRQoL) in Saudi patients with sickle cell disease (SCD), particularly among adult populations. The aim of the current study was to describe the characteristics of SCD patients and their impact on their quality of life (QoL). METHODS: Six hundred twenty-nine adult SCD patients who attended King Fahad Hospital in Hofuf and King Fahad Central Hospital in Jazan were included in the analysis. Demographic/clinical data were collected and an Arabic version of the Medical Outcomes 36-Item Short-Form Health Survey (SF-36) questionnaire was used to assess QoL. RESULTS: SCD patients who hold a university degree reported positive impacts on the following domains of SF-36: physical role function, vitality, emotional well being, social function, pain reduction, and general health (P = .002, P = .001, P = .001, P = .003, P = .004, and P = .001, respectively). In general, patients with fever, skin redness, swelling, or history of blood transfusion tended to impair the health status of the SF-36. A multivariate analysis revealed that patients with a university degree tended to report high scores of physical role functions, emotional role function, and vitality. Patients with regular exercise tend to increase vitality, social function, general health, and reduce pain. Unemployment tends to lessen vitality and worsen pain. On average, pain, social function, and physical function scores tended to worsen in patients with swelling or history of blood transfusion. CONCLUSIONS: This study highlighted that poor education, fever, skin redness, and swelling were negatively associated with specific components of SF-36. SCD patients with a history of blood transfusion found their QoL poorer, whereas regular exercise tended to improve QoL.

RESUMEN

BACKGROUND: If and how much dural penetration influences long-term outcome after traumatic brain injury (TBI) is understudied, especially within the civilian population. OBJECTIVES: Using the large TBI Model Systems cohort, this study assessed and compared penetrating TBI (PTBI) and closed TBI with respect to global outcome and late seizures 2 years after injury. METHODS: After performing unadjusted PTBI versus closed TBI comparisons, multivariate regression models were built and analyzed for both outcomes by including the following additional predictors: length of unconsciousness, posttraumatic amnesia duration, hospital length of stay, age, gender, race, marital status, education level, problem substance abuse, and preinjury employment status. RESULTS: The collapsed Glasgow Outcome Scale model (n = 6111) showed significant secondary effects of PTBI with employment status. When employed before injury, individuals with PTBI were 2.62 times more likely (95% confidence interval, 1.92-3.57) to have a lower Glasgow Outcome Scale category. The final model for late seizures (n = 6737) showed a significant main effect for PTBI. Adjusting for other predictors, individuals with PTBI were 2.78 times more likely (95% confidence interval, 1.93-3.99) than those with closed TBI to be rehospitalized for a seizure. CONCLUSION: This study empirically demonstrates that penetrating injury mechanism has important prognostic implications.

RESUMEN

In noninferiority studies, a limit of indifference is used to express a tolerance in results such that the clinician would regard such results as being acceptable or 'not worse'. We applied this concept to a measure of accuracy, the Receiver Operating Characteristic (ROC) curve, for a sequence of tests. We expressed a limit of indifference for the range of acceptable sensitivity values and examined the associated cost of testing within this range. In doing so, we generated the minimum cost maximum ROC (MCMROC) curve, which reflects the reduced sensitivity and cost of testing. We compared the MCMROC and its associated cost curve between limits of indifference set to 0.999 [a 0.1% reduction in true positive rate (TPR)], 0.95 (a 5% reduction in TPR), and 1 (no reduction in TPR). The limit of indifference tended to have less of an effect on the MCMROC curves than on the associated cost curves that were greatly affected. Cost was reduced at high false positive rates (FPRs) at higher limit of indifference (0.999) and at small FPRs as the limit of indifference decreased (0.95). These patterns were also observed as applied to sequential strategies used to diagnose diabetes in the Pima Indians.

RESUMEN

The practice of sequential testing is followed by the evaluation of accuracy, but not by the evaluation of cost. This paper focuses on three logic rules for combining two sequences of tests: believe the positive (BP), which diagnoses disease if any of two tests is positive, believe the negative (BN), which diagnoses disease if any of two tests is negative, and believe the extreme (BE), which diagnoses disease if the first test is positive or, after a first inconclusive test, a second test is positive for disease. Comparisons of these strategies are provided in terms of accuracy using false positive rate, sensitivity pairs that make up the maximum receiver operating characteristic curve, and cost of testing, defined as the proportion of subjects needing two tests to diagnose disease. A method to incorporate the cost of testing into the definition of the optimal operating point is also presented. The performance of the testing strategies is examined with respect to the ratio of standard deviations and the correlation between test results under the bivariate normal assumptions. Under all parameter settings, the maximum receiver operating characteristic curve of the BE strategy never performed worse than the BN and BP strategies; the BE strategy also had the lowest cost. The use of body mass index and plasma glucose concentration to diagnose diabetes in Pima Indians was presented as a real-world application. The optimal operating points found by the BN and BE strategies produce lower false positive rate values than the BP strategy for these data.

RESUMEN

OBJECTIVE: Somatic symptoms have been extensively studied in primary care, but infrequently in diseases causing pain in multiple sites. We therefore examined the impact of somatic symptom burden (SSB) on pain, depression, anxiety, health-care utilization, and quality-of-life in adults with sickle cell disease (SCD). METHODS: Subjects were 230 adults in the prospective Pain in Sickle Cell Epidemiology Study (PiSCES). Baseline data included demographics, genotype, Patient Health Questionnaire (PHQ), and SF-36 health-related quality of life (HRQOL). In daily diaries for 6 months, patients recorded SCD pain and SCD health-care utilization. To exclude common SCD pain sites, we abridged the PHQ's 15 somatic symptoms to 11 (PHQscd). We divided subjects into two groups: PHQscd≥11 (high SSB), and PHQscd<11 (low SSB). RESULTS: High SSB occurred in 18.3% of subjects and was more frequent in women than men (24.6% vs. 9.1%, p=0.0033). Sixty percent of subjects with anxiety and 37.5% of those with depression had comorbid high SSB. Percentage of pain days not in crisis pain was significantly higher in somatizers, but crisis pain did not differ between groups. The high SSB group's hospitalization, scheduled doctor visits, and overall utilization, particularly on non-crisis days were significantly higher than the low SSB group's (p values < 0.05). All SF-36 subscales were significantly negatively correlated with PHQscd (p<0.0001). CONCLUSIONS: Even after excluding common SCD pain complaints, high somatic symptom burden was 1.5 to 2 times more prevalent in SCD patients than in primary care. High SSB in SCD predicts more non-crisis pain and healthcare utilization for pain, and is associated with depression, anxiety, and poorer HRQOL.

RESUMEN

BACKGROUND: The usefulness of laboratory tests in the decision-making process with regard to early identification of dengue virus infection has not been widely reported, particularly the aspartate aminotransferase (AST)/platelet count ratio index during a patient's days of illness. The aim of this study was to examine the pattern of the ratio index over the course of illness and identify whether it is a marker of dengue virus infection in dengue patients, as well as to assess the role of other laboratory tests. METHODS: A chart review of 205 dengue patients was analyzed using available records of 845 laboratory results within different time intervals or exam dates during the course of illness. We used repeated measures mixed binary logistic regression analyses to model the dengue virus infection, defined as giving at least one positive antibody test (yes/no). RESULTS: The high risk of dengue virus infection in dengue patients was found in the male gender (adjusted OR=4.316, 95% CI: 1.285-14.498, P=0.018), in patients with a high AST/platelet count ratio index (adjusted OR=1.438, 95% CI: 1.057-1.957, P=0.021), in patients with a low MCV level (adjusted OR=0.815, 95% CI: 0.679-0.978, P=0.028), and in patients with a low ALT level (adjusted OR=0.996, 95% CI: 0.993-0.999, P=0.010). CONCLUSION: Laboratory markers, in particular the AST/platelet count ratio index, can be useful for clinicians to strengthen the decision-making process in primary care settings. Furthermore, our model revealed that low MCV and low ALT are predictors of the dengue virus infection, while being a male increases the risk of dengue virus infection. More studies are needed to evaluate the impact of the AST/platelet count ratio index on the severity of dengue fever infection during the onset of symptoms and course of treatment.

RESUMEN

STUDY OBJECTIVE: Patients with sickle cell disease often receive a substantial amount of their health care in the emergency department (ED) and some come to the ED frequently, seeking treatment for pain. As a result, patients with sickle cell disease are often stigmatized as opioid-seeking ED overutilizers. We describe the proportion of sickle cell disease patients who are high utilizers of the ED and compare them with other sickle cell disease patients on demographics, pain characteristics, health data, psychosocial characteristics, and quality of life. METHODS: Two hundred thirty-two patients completed baseline data and at least 30 days of daily diary data. Baseline data included demographics, health data, and quality of life (Medical Outcome Study 36 Item Short Form). Daily diary data included ED utilization for sickle cell pain and descriptors of pain and distress. RESULTS: Eighty-two (35.5%) patients were found to be high ED utilizers. Clinically important and statistically significant differences were found between high ED utilizers and all other sickle cell disease patients: lower hematocrit level, more transfusions, more pain days, more pain crises, higher mean pain and distress, and worse quality of life on Medical Outcome Study 36 Item Short Form physical function summary scales. After controlling for severity and frequency of pain, high ED utilizers did not use opioids more frequently than other sickle cell disease patients. CONCLUSION: A substantial minority of sickle cell disease patients are high ED utilizers. However, high ED utilizers with sickle cell disease are more severely ill as measured by laboratory variables, have more pain, more distress, and have a lower quality of life.

RESUMEN

BACKGROUND: Researchers of sickle cell disease have traditionally used health care utilization as a proxy for pain and underlying vaso-occlusion. However, utilization may not completely reflect the amount of self-reported pain or acute, painful episodes (crises). OBJECTIVE: To examine the prevalence of self-reported pain and the relationship among pain, crises, and utilization in adults with sickle cell disease. DESIGN: Prospective cohort study. SETTING: Academic and community practices in Virginia. PATIENTS: 232 patients age 16 years or older with sickle cell disease. MEASUREMENTS: Patients completed a daily diary for up to 6 months, recording their maximum pain (on a scale of 0 to 9); whether they were in a crisis (crisis day); and whether they used hospital, emergency, or unscheduled ambulatory care for pain on the previous day (utilization day). Summary measures included both simple proportions and adjusted probabilities (for repeated measures within patients) of pain days, crisis days, and utilization days, as well as mean pain intensity. RESULTS: Pain (with or without crisis or utilization of care) was reported on 54.5% of 31 017 analyzed patient-days (adjusted probability, 56%). Crises without utilization were reported on 12.7% of days and utilization on only 3.5% (unadjusted). In total, 29.3% of patients reported pain in greater than 95% of diary days, whereas only 14.2% reported pain in 5% or fewer diary days (adjusted). The frequency of home opiate use varied and independently predicted pain, crises, and utilization. Mean pain intensity on crisis days, noncrisis pain days, and total pain days increased as the percentage of pain days increased (P < 0.001). Intensity was significantly higher on utilization days (P < 0.001). However, utilization was not an independent predictor of crisis, after controlling for pain intensity. LIMITATIONS: The study was done in a single state. Patients did not always send in their diaries. CONCLUSION: Pain in adults with sickle cell disease is the rule rather than the exception and is far more prevalent and severe than previous large-scale studies have portrayed. It is mostly managed at home; therefore, its prevalence is probably underestimated by health care providers, resulting in misclassification, distorted communication, and undertreatment.

RESUMEN

OBJECTIVE: To examine general health decision-making roles among African American men ages 40 to 70 recruited in barbershops in the Richmond, Virginia, metropolitan area. METHODS: We adapted the 1-item Control Preference scale to study the associations between health decision-making role preferences and demographic variables. Forty African-American men were recruited from barbershops to complete a self-administered survey. After performing descriptive statistics, we dichotomized our outcome into active vs nonactive (collaborative or passive) decision makers. Data were then analyzed using chi2, Wilcoxon-Mann-Whitney rank sum, and multiple logistic regression. RESULTS: Fifteen subjects responded that they engaged in active decision making, 20 in collaborative, and 5 in passive decision making. Almost all (86.7%) active decision makers were home owners, vs 41.7% of nonactive decision makers. Among active decision makers, 46.7% had incomes of more than $70000, vs 12.5% of nonactive decision makers. The active group reported health status that was good to excellent, while 20.8% of those in the nonactive group reported poor/fair health. CONCLUSION: African American male barbershop clients preferred an active or collaborative health decision-making role with their physician, rather than a passive role. The relationship among home ownership, income, and decision style may best be understood by considering the historical and cultural influences on gender role socialization among African American males. More comprehensive assessment of decision styles is necessary to better understand health decision making among African American male patients.

RESUMEN

OBJECTIVE: To develop a survey instrument to identify adult sickle cell disease (SCD) patients on chronic opioid therapy who are at-risk for opioid abuse. DESIGN: Prospective survey and interview. SETTING: Adult SCD clinic in a large urban teaching facility. PATIENTS/PARTICIPANTS: Convenience sampling of adult patients presenting to the sickle cell clinic. INTERVENTIONS: None. MAIN OUTCOME: Primary outcome was "at-risk for opioid misuse," defined as at least 3/8 "yes" answers (a positive composite score) on the Prescription Opioid Misuse Index (POMI) questionnaire. Secondary outcome was DSM-IV criteria for substance abuse using the DSM IV Diagnostic Interview Schedule. RESULTS: Of the 99 patients who completed the POMI, the mean age was 36 years; 58.6 percent were female, 48 percent were hemoglobin SS (47/99), and 26 percent were SC (26/99). Twenty-four percent (24/99) were identified as at-risk for opioid misuse using the POMI. There were no differences in demographic, SCD genotype, or socioeconomic variables for at-risk versus not-at-risk patients. CONCLUSION: Twenty-four percent of unselected adult SCD patients on opioids were identified as at-risk for opioid misuse using a quick survey. This may represent as much as 2.5-7 times the national misuse rate. This group of patients may benefit from additional diagnostic and therapeutic interventions to help understand and manage their opioid usage.

RESUMEN

BACKGROUND: Despite the continuing increase in the breast cancer incidence rate among Saudi Arabian women, no breast cancer risk-prediction model is available in this population. The aim of this research was to develop a risk-assessment tool to distinguish between high risk and low risk of breast cancer in a sample of Saudi women who were screened for breast cancer. METHODS: A retrospective chart review was conducted on symptomatic women who underwent breast mass biopsies between September 8, 2015 and November 8, 2017 at King Abdulaziz Medical City, Riyadh, Saudi Arabia. RESULTS: A total of 404 (63.8%) malignant breast biopsies and 229 (36.2%) benign breast biopsies were analyzed. Women ≥40 years old (aOR: 6.202, CI 3.497-11.001, P=0.001), hormone-replacement therapy (aOR 24.365, 95% CI 8.606-68.987, P=0.001), postmenopausal (aOR 3.058, 95% CI 1.861-5.024, P=0.001), and with a family history of breast cancer (aOR 2.307, 95% CI 1.142-4.658, P=0.020) were independently associated with an increased risk of breast cancer. This model showed an acceptable fit and had area under the receiver-operating characteristic curve of 0.877 (95% CI 0.851-0.903), with optimism-corrected area under the curve of 0.865. CONCLUSION: The prediction model developed in this study has a high ability in predicting increased breast cancer risk in our facility. Combining information on age, use of hormone therapy, postmenopausal status, and family history of breast cancer improved the degree of discriminatory accuracy of breast cancer prediction. Our risk model may assist in initiating population-screening programs and prompt clinical decision making to manage cases and prevent unfavorable outcomes.
