A theoretical explanation of naloxone provision among primary care physicians and community pharmacists in Tennessee.

BACKGROUND: Increasing access to naloxone reduces opioid-related morbidity and mortality. Primary care and community pharmacy settings are critical access points, yet limited theoretical research has examined naloxone prescribing and dispensing behaviors. OBJECTIVES: To determine if the theory of planned behavior (TPB) combined with theoretical constructs from communication science explains intentions to co-prescribe and discuss co-dispensing naloxone among primary care physicians and community pharmacists, respectively. METHODS: This cross-sectional study surveyed cohorts of licensed primary care physicians and community pharmacists in Tennessee in 2017. Intentions were measured using profession-specific case vignettes, whereby they were asked given 10 similar patients, how many times (0-10) would they co-prescribe or discuss co-dispensing naloxone. Bivariate and multivariable analyses were used. RESULTS: The analytic sample included 295 physicians (response rate = 15.6 %) and 423 pharmacists (response rate = 19.4 %). Approximately 65 % of physicians reported never intending to co-prescribe naloxone (0 out of 10 patients), while 47 % of pharmacists reported never intending to discuss co-dispensing. All TPB constructs-attitudes (AOR = 1.32, CI = 1.16-1.50), subjective norms (AOR = 1.17, CI = 1.06-1.30), and perceived behavioral control (AOR 1.16, CI = 1.02-1.33)-were associated with an increased likelihood of pharmacists always (versus never) discussing co-dispensing. Similarly, two TPB constructs-attitudes (AOR = 1.41, CI = 1.19-1.68) and subjective norms (AOR = 1.22, CI = 1.08-1.39)-were associated with an increased likelihood of physicians always co-prescribing. Among physicians only, one communication construct-self-perceived communication competence (AOR = 1.19, CI = 1.01-1.41)-was associated with an increased likelihood of always co-prescribing. CONCLUSION: Findings support the value of theory, particularly TPB, in explaining primary care physician intentions to co-prescribe and community pharmacist intentions to discuss co-dispensing naloxone.

What factors are associated with anaemia in pregnancy among Nigerian women? Evidence from a national survey.

Background: Anaemia in pregnancy remains a severe public health problem in sub-Saharan African countries including Nigeria. Objectives: To assess factors associated with anaemia in pregnancy among Nigerian women. Methods: A secondary analysis of the 2018 Nigeria demographic health survey was conducted to determine the predictors of anaemia among Nigerian pregnant women (N=1522). SAS 9.4 was used for the analysis. Results: The prevalence of anaemia in pregnancy was 61.1%. On multivariable logistic regression analysis, women in the North-central (AOR=2.52, CI=1.46-4.35) and South-south (AOR=2.21, CI=1.06-4.59) had increased odds of anaemia in pregnancy, compared to those in the Northwest. Women with no education (AOR=2.38, CI=1.28-4.44), primary education (AOR=3.06, CI=1.58-5.96) and secondary education (AOR=1.75, CI=1.04-2.94) had increased odds of anaemia in pregnancy compared to women with teriary education. Also, women not in marital union had increased odds of anaemia in pregnancy compared to women in a union (AOR=2.56, CI=1.15-5.72). Women in the second (AOR=2.42, CI=1.79-3.29) and third trimesters of pregnancy (AOR=2.83, CI=2.07-3.89) had increased odds of anaemia. Conclusion: These findings are important for the control of anemia among pregnant Nigerian women. Women in the Northcentral and Southsouth zones are particularly at risk for anaemia in pregnancy and should receive special attention during antenatal care.

A novel, microvascular evaluation method and device for early diagnosis of peripheral artery disease and chronic limb-threatening ischemia in individuals with diabetes.

Objective: A novel transdermal arterial gasotransmitter sensor (TAGS) has been tested as a diagnostic tool for lower limb microvascular disease in individuals with and without diabetes mellitus (DM). Methods: The TAGS system noninvasively measures hydrogen sulfide (H2S) emitted from the skin. Measurements were made on the forearm and lower limbs of individuals from three cohorts, including subjects with DM and chronic limb-threatening ischemia, to evaluate skin microvascular integrity. These measurements were compared with diagnosis of peripheral artery disease (PAD) using the standard approach of the toe brachial index. Other measures of vascular health were made in some subjects including fasting blood glucose, hemoglobin A1c, plasma lipids, blood pressure, estimated glomerular filtration, and body mass index. Results: The leg:arm ratio of H2S emissions correlated with risk factors for microvascular disease (ie, high-density lipoprotein levels, estimated glomerular filtration rate, systolic blood pressure, and hemoglobin A1c). The ratios were significantly lower in symptomatic DM subjects being treated for chronic limb-threatening ischemia (n = 8, 0.48 ± 0.21) compared with healthy controls (n = 5, 1.08 ± 0.30; P = .0001) and with asymptomatic DM subjects (n = 4, 0.79 ± 0.08; P = .0086). The asymptomatic DM group ratios were also significantly lower than the healthy controls (P = .0194). Using ratios of leg:arm transdermal H2S measurement (17 subjects, 34 ratios), the overall accuracy to identify limbs with severe PAD had an area under the curve of the receiver operating curve of 0.93. Conclusions: Ratios of transdermal H2S measurements are lower in legs with impaired microvascular function, and the decrease in ratio precedes clinically apparent severe microvascular disease and diabetic ulcers. The TAGS instrument is a novel, sensitive tool that may aid in the early detection and monitoring of PAD complications and efforts for limb salvage.

Primary care physicians' opioid-related prevention behaviors and intentions: A descriptive analysis.

OBJECTIVE: Primary care physicians (PCPs) are positioned to mitigate opioid morbidity and mortality, but their engagement in primary, secondary, and tertiary opioid-related prevention behaviors is unclear. The objective of this study was to evaluate Tennessee PCPs' engagement in and intention to engage in multiple opioid-related prevention behaviors. METHODS: A survey instrument was developed, pretested, and pilot tested with practicing PCPs. Thereafter, a census of eligible Tennessee PCPs was conducted using a modified, four-wave tailored design method approach. Three patient scenarios were employed to assess physician intention to engage in 10 primary, secondary, and tertiary prevention behaviors. Respondents were asked to report, given 10 similar scenarios, the number of times (0-10) they would engage in prevention behaviors. Descriptive statistics were calculated using SPSS version 25. RESULTS: A total of 296 usable responses were received. Physician intention to engage in prevention behaviors varied across the 10 behaviors studied. Physicians reported frequently communicating risks associated with prescription opioids to patients (8.9 ± 2.8 out of 10 patients), infrequently utilizing brief questionnaires to assess for risk of opioid misuse (1.7 ± 3.3 out of 10 patients), and screening for current opioid misuse (3.1 ± 4.3 out of 10 patients). Physicians reported seldomly co-prescribing naloxone for overdose reversal and frequently discharging from practice patients presenting with an opioid use disorder. CONCLUSIONS: This study noted strengths and opportunities to increase engagement in prevention behaviors. Understanding PCPs' engagement in opioid-related prevention behaviors is important to effectively target and implement morbidity and mortality reducing interventions.

Perceived Barriers to Contraceptive Access and Acceptance among Reproductive-Age Women Receiving Opioid Agonist Therapy in Northeast Tennessee.

OBJECTIVES: Women with substance use disorders experience unique challenges to contraceptive obtainment and user-dependent method adherence, contributing to higher than average rates of unintended pregnancy. This study estimated the prevalence of barriers to contraception and their associations with contraceptive use and unwanted pregnancies among women receiving opioid agonist therapy (OAT) in northeast Tennessee. METHODS: A cross-sectional survey was piloted among female patients aged 18 to 55 years from 2 OAT clinics. Logistic regression was used to evaluate associations between contraceptive barriers and current contraceptive use and previous unwanted pregnancies among women receiving OAT. RESULTS: Of 91 participants, most experienced previous pregnancies (97.8%), with more than half reporting unwanted pregnancies (52.8%). Although 60% expressed a strong desire to avoid pregnancy, ambivalence toward becoming pregnant was common (30.0%). Most experienced ≥1 barriers to contraceptive use or obtainment (75.8%), the most prevalent being aversion to adverse effects (53.8%), healthcare provider stigmatization (30.7%), scheduled appointment compliance (30.3%), and prohibitive cost (25.0%). Experience of any contraceptive barrier (adjusted odds ratio [AOR] 8.64, 95% confidence interval [CI] 2.03-36.79) and access to a contraceptive provider (AOR 5.01, 95% CI 1.34-18.77) were positively associated with current use of prescribed contraceptives, whereas prohibitive cost was negatively associated (AOR 0.28, 95% CI 0.08-0.94). CONCLUSIONS: Although most participants desired to avoid pregnancy, ambivalence or uncertainty of pregnancy intention was common. Most experienced barriers to contraception, which were more strongly associated with previous unwanted pregnancy than current contraceptive use. The provision of long-acting reversible contraceptives and contraceptive education at OAT clinics represents an opportunity to reduce the incidence of neonatal abstinence syndrome.
