Predictors of HIV Preexposure Prophylaxis Initiation Among Public Health Clients in Rural and Small Urban Areas in Iowa

OBJECTIVE

Preexposure prophylaxis (PrEP) is a safe and effective method for HIV prevention, but little is known about PrEP uptake in rural and small urban areas. We described rates and predictors of HIV PrEP initiation among public health clients in rural and small urban areas in Iowa.

METHODS

This was a prospective cohort study of clients with PrEP indications served by HIV testing and disease intervention specialist/partner services (DIS/PS) programs in public health departments in Iowa from February 1, 2018, through February 28, 2019. Eligible participants were aged 18-70 and referred for PrEP by public health personnel. Participants completed surveys at enrollment addressing demographic characteristics; sexual history; previous drug use; PrEP experiences; and knowledge, attitudes, and beliefs about PrEP. A follow-up survey assessed PrEP initiation at 30 days. We compared baseline characteristics of PrEP initiators and non-initiators.

RESULTS

Two hundred thirty-four public health clients consented to participate in the study; 189 completed the baseline survey, and 117 (61.9%) completed the follow-up survey. The mean age of participants in the baseline survey was 30 (range, 18-68); 109 (57.7%) were male, 127 (67.2%) were White, and 169 (89.4%) lived in a rural or small urban area. Of 117 participants in the follow-up survey, those who initiated PrEP were significantly more likely than those who did not initiate PrEP to be referred by DIS/PS programs (46.7% vs 7.8%, P < .001) and to recognize that PrEP was ≥90% effective (86.7% vs 35.3%, P = .001). No PrEP initiators and 8 PrEP non-initiators agreed that PrEP is for promiscuous people (0% vs 7.8%, P = .04). Perceived PrEP stigma was low and not associated with PrEP initiation.

CONCLUSIONS

PrEP initiation rates were low among rural and small urban health department clients. Interventions are needed to improve linkage to PrEP among rural and small urban public health clients.

1299. Iowa TelePrEP: Preliminary Experience with a Public Health-Partnered, Telemedical PrEP Delivery Model in a Rural State

Background

Access to HIV pre-exposure prophylaxis (PrEP) is often poor in small urban and rural areas due to long distances to PrEP providers and stigma. In 2017, the Iowa Department of Public Health (IDPH), University of Iowa (UI), and community representatives collaborated to develop a public health-partnered telemedical PrEP delivery model to overcome these barriers (TelePrEP). IDPH personnel working in five sexually transmitted infection (STI) clinics and partner services (PS) programs in Eastern Iowa screened clients for PrEP indications and referred those with need to TelePrEP pharmacist providers at UI. Via collaborative practice, pharmacists completed initial and follow-up PrEP home video visits with clients on smart phones and laptops. Clients obtained laboratory monitoring and STI screening in public health-affiliated and local laboratories in accordance with USPHS/CDC guidelines, and received PrEP medication by mail. PS personnel linked TelePrEP clients with newly-identified STIs to local treatment.

Methods

Using the PrEP continuum as framework, we used IDPH databases and UI medical records to conduct a retrospective process evaluation of the TelePrEP model (February 2017–April 2018).

Results

TelePrEP received 44 referrals from public health and 59 self-referrals via advertising. Pharmacists completed 84 initial visits (81% of referrals), including 37 visits (84%) with clients referred by public health. Most (94%) started emtricitabine/tenofovir after initial visits. Retention in TelePrEP at 6 months was 87%. 96% of guideline-indicated laboratory tests (HIV, creatinine, STI, hepatitis) were completed at baseline and follow-up. Rates of extragenital chlamydia and gonorrhea screening were lower (74 of 104 completed screens) due to variable availability of swabs at local laboratories. 15 clients were diagnosed with 20 STIs on screening (6 syphilis, four gonorrhea, 10 chlamydia) and one unrecognized pregnancy was identified. PS linked all clients with STIs on screens to treatment within 14 days (80% in 3 days).

Conclusion

Using telemedicine, healthcare systems can partner with public health administered STI clinics and PS programs to create virtual PrEP delivery models in rural settings. Public health partnerships enhance client identification and ensure linkage to care for new STI diagnoses in telemedicine programs.

Large-Scale Evaluation of Quality of Care in 6 Countries of Eastern Europe and Central Asia Using Clinical Performance and Value Vignettes

When providers in 6 different countries were asked how they would care for the same patient, there was wide variation within and between countries. Nevertheless, 11% of the physicians scored over 80%, suggesting good quality of care is possible even with resource constraints. Use of validated clinical vignettes, which can be applied affordably at scale, could help improve quality of services in low- and middle-income countries.

Background:

A significant determinant of population health outcomes is the quality of care provided for noncommunicable diseases, obstetric, and pediatric care. We present results on clinical practice quality in these areas as measured among nearly 4,000 providers working at more than 1,000 facilities in 6 Eastern European and Central Asian countries.

Methods:

This study was conducted between March 2011 and April 2013 in Albania, Armenia, Georgia, Kazakhstan, Kirov Province in Russia, and Tajikistan. Using a probability proportional-to-size sampling technique, based on number of hospital beds, we randomly selected within each country 42 hospitals and their associated primary health care clinics. Physicians and midwives within each clinical area of interest were randomly selected from each hospital and clinic and asked how they would care for simulated patients using Clinical Performance and Value (CPV) vignettes. Facility administrators were also asked to complete a facility survey to collect structural measures of quality. CPV vignettes were scored on a scale of 0% to 100% for each provider. We used descriptive statistics and t tests to identify significant differences in CPV scores between hospitals and clinics and rural vs. urban facilities, and ANOVA to identify significant differences in CPV scores across countries.

Results:

We found that quality of care, as concurrently measured by performance on CPV vignettes, was generally poor and widely variable within and between countries. Providers in Kirov Province, Russia, had the highest overall performance, with an average score of 70.8%, while providers in Albania and Tajikistan had the lowest average score, each at 50.8%. The CPV vignettes with the lowest scores were for multiple noncommunicable disease risk factors and birth asphyxia. A considerable proportion (11%) of providers performed well on the CPV vignettes, regardless of country, facility, or structural resources available to them.

Conclusions:

Countries of Eastern Europe and Central Asia are challenged by poor performance as measured by clinical care vignettes, but there is potential for provision of high-quality care by a sizable proportion of providers. Large-scale assessments of quality of care have been hampered by the lack of effective measurement tools that provide generalizable and reliable results across diverse economic, cultural, and social settings. The feasibility of quality measurement using CPV vignettes in these 6 countries and the ability to combine results with individual feedback could significantly enhance strategies to improve quality of care, and ultimately population health.

Cognitive and daily functioning in older adults with vegetative symptoms of depression

OBJECTIVES

In primary care 50-95% of patients with depression present with vegetative symptoms (VS). Based on the extant literature, older adults showing VS (but no dysphoria) may show functional impairment but this hypothesis has not been empirically tested. The goal of this study was to examine neurocognitive and daily functioning of elderly patients showing exclusively VS in comparison with patients presenting with VS and dysphoria.

METHODS

Seven hundred and eighty-seven primary care patients received measures of neurocognition and daily functioning. Neurocognition was measured with the repeatable battery for the assessment of neuropsychological status (RBANS). Three groups were compared: (1) patients with two or more VS of depression without dysphoria (VS - D), (2) patients with at least one VS and dysphoria (VS + D), and (3) comparison patients without multiple VS or dysphoria.

RESULTS

Nearly one third of the sample (31%) fell into the VS - D group, whereas 15% fell into the VS + D group. Both VS groups showed poorer neurocognition and activities of daily living than comparisons. Only one subtest of the RBANS (i.e., picture naming) showed a significant difference between VS + D and VS - D, and there was no significant difference on daily functioning. VS - D patients reported less frequent past history of depression and endorsed less anxiety compared to VS + D.

CONCLUSIONS

Elderly patients presenting with clusters of VS with or without dysphoria show poorer neurocognitive and functional performance. Relative poorer cognition and daily functioning in VS - D are potential harbingers of further decline and consistent with under-reporting of sadness in older age.

Anticholinergic medications in community-dwelling older veterans: prevalence of anticholinergic symptoms, symptom burden, and adverse drug events

BACKGROUND

The use of drugs with anticholinergic adverse effects is often deemed inappropriate in elderly (aged > or = 65 years) patients, yet studies continue to show extensive use in this population at high risk for adverse drug events (ADEs). The burden of drug-related anticholinergic symptoms in community-dwelling elderly patients has not been well described.

OBJECTIVE

The aim of this study was to assess the prevalence of anticholinergic symptoms, corresponding symptom burden, and anticholinergic-related ADEs in a sample of community-dwelling elderly veterans.

METHODS

This prospective cohort study was conducted at the primary care clinics at the Veterans Affairs Medical Center (VAMC), Iowa City, Iowa. The study sample included randomly selected patients with intact cognitive function attending the VAMC and prescribed > or = 5 scheduled medications. Data on current prescription and nonprescription drug use were elicited by a trained research assistant and a clinical pharmacist from patient interviews and electronic medical records. The prevalence and severity of 7 anticholinergic symptoms (dry mouth, constipation, blurred vision, confusion, urinary hesitation, dry eyes, and drowsiness) were assessed at baseline. The occurrence of ADEs at 12 weeks was compared between patients using anticholinergic drugs and those not using them.

RESULTS

A total of 532 patients were included (97.9% men; mean age, 74.3 years; 27.1% used at least 1 anticholinergic drug). Twenty-two anticholinergic drugs (16 prescription medications, 6 over-the-counter medications) were identified. The mean number of anticholinergic symptoms was significantly higher in the group using anticholinergic drugs (3.1 vs 2.5; P < 0.01). However, only 2 symptoms were statistically more prevalent in the group using anticholinergic drugs: dry mouth (57.6% vs 45.6%) and constipation (42.4% vs 29.4%) (both, P < 0.01). At 12 weeks, only 1 (0.8%) patient in the group using anticholinergic drugs reported an ADE considered related to an anticholinergic drug.

CONCLUSIONS

Anticholinergic drug use was common (27.1%) in these elderly veterans with intact cognitive function. The mean number of anticholinergic symptoms was significantly greater in this group, and the prevalences of dry mouth and constipation were significantly higher in the group using anticholinergic drugs (all, P < 0.01). Anticholinergic-related ADEs were rare (0.8%). Although anticholinergic drugs should generally be avoided in the elderly, individual risks and benefits for a patient should be considered.

Anxiety and impaired social function in the elderly

The effect of anxiety on impairment in activities of daily living was examined among elderly individuals residing in a long-term care setting. Eighty one subjects received complete assessments of psychiatric symptoms, cognitive impairment, and ability to perform daily living tasks. A multivariate analysis was conducted to determine the relative influence of anxiety, cognitive status, and depressive symptoms on daily living skills. The presence of anxiety was significantly associated with reduced functional status in performing activities of daily living. This relationship remained significant even after controlling for the presence of concurrent depressive symptoms as well as cognitive impairment. Anxiety is a significant source of morbidity among elderly individuals and substantially impairs social function over and above the effects of depression and cognitive decline. Current interventions for anxiety such as benzodiazepines may have adverse cognitive effects, hence more specific intervention strategies for anxiety may be very important for this population.

Xyloglucan (amyloid) formation in the cotyledons of Tropaeolum majus L. seeds

Mature seeds of Tropaeolum majus L. contain the cell wall polysaccharide xyloglucan (amyloid), protein and lipid as storage substances. The transitory occurrence of starch during the process of seed development could be substantiated.[U-(14)C]-labelled xylose, glucose and glucuronic acid were fed to ripening seeds and the incorporation of radioactivity into xyloglucan, starch and the sugar nucleotide fraction of the cotyledons was determined. The results indicate that exogenous supplied xylose is not incorporated directly into xyloglucan, but is transformed to glucose before incorporation into xyloglucan and starch. Radioactivity from glucuronic acid was predominantly found in the xylose moiety of xyloglucan. Incubation of seeds with [6-(14)C]-labelled glucose resulted in an incorporation of labelled hexoses into amyloid and starch, whereas xylose residues of amyloid remained unlabelled.
