Hypertension and depression are increasingly common noncommunicable diseases in Ghana and worldwide, yet both are poorly controlled. We sought to understand how healthcare workers in rural Ghana conceptualize the interaction between hypertension and depression, and how care for these two conditions might best be integrated. We conducted a qualitative descriptive study involving in-depth interviews with 34 healthcare workers in the Kassena-Nankana districts of the Upper East Region of Ghana. We used conventional content analysis to systematically review interview transcripts, code the data content and analyze codes for salient themes. Respondents detailed three discrete conceptual models. Most emphasized depression as causing hypertension: through both emotional distress and unhealthy behavior. Others posited a bidirectional relationship, where cardiovascular morbidity worsened mood, or described a single set of underlying causes for both conditions. Nearly all proposed health interventions targeted their favored root cause of these disorders. In this representative rural Ghanaian community, healthcare workers widely agreed that cardiovascular disease and mental illness are physiologically linked and warrant an integrated care response, but held diverse views regarding precisely how and why. There was widespread support for a single primary care intervention to treat both conditions through counseling and medication.

PURPOSE/OBJECTIVE:We undertook a trial to test the efficacy of a technology-assisted health coaching intervention for weight management, called Goals for Eating and Moving (GEM), within primary care. METHODS:). The primary outcome (weight change at 12 months) and exploratory outcomes (eg, program attendance, diet, physical activity) were analyzed according to intention to treat. RESULTS:= .48). There were no statistically significant differences in secondary outcomes. Exploratory analyses showed that the GEM arm had a greater change than the EUC arm in mean number of weekly minutes of moderate to vigorous physical activity other than walking, a finding that may warrant further exploration. CONCLUSIONS:The GEM intervention did not achieve clinically important weight loss in primary care. Although this was a negative study possibly affected by health system resource limitations and disruptions, its findings can guide the development of similar interventions. Future studies could explore the efficacy of higher-intensity interventions and interventions that include medication and bariatric surgery options, in addition to lifestyle modification.

BACKGROUND:During the COVID-19 pandemic, acute respiratory infection (ARI) antibiotic prescribing in ambulatory care markedly decreased. It is unclear if antibiotic prescription rates will remain lowered. METHODS:We used trend analyses of antibiotics prescribed during and after the first wave of COVID-19 to determine whether ARI antibiotic prescribing rates in ambulatory care have remained suppressed compared to pre-COVID-19 levels. Retrospective data was used from patients with ARI or UTI diagnosis code(s) for their encounter from 298 primary care and 66 urgent care practices within four academic health systems in New York, Wisconsin, and Utah between January 2017 and June 2022. The primary measures included antibiotic prescriptions per 100 non-COVID ARI encounters, encounter volume, prescribing trends, and change from expected trend. RESULTS:At baseline, during and after the first wave, the overall ARI antibiotic prescribing rates were 54.7, 38.5, and 54.7 prescriptions per 100 encounters, respectively. ARI antibiotic prescription rates saw a statistically significant decline after COVID-19 onset (step change -15.2, 95% CI: -19.6 to -4.8). During the first wave, encounter volume decreased 29.4% and, after the first wave, remained decreased by 188%. After the first wave, ARI antibiotic prescription rates were no longer significantly suppressed from baseline (step change 0.01, 95% CI: -6.3 to 6.2). There was no significant difference between UTI antibiotic prescription rates at baseline versus the end of the observation period. CONCLUSIONS:The decline in ARI antibiotic prescribing observed after the onset of COVID-19 was temporary, not mirrored in UTI antibiotic prescribing, and does not represent a long-term change in clinician prescribing behaviors. During a period of heightened awareness of a viral cause of ARI, a substantial and clinically meaningful decrease in clinician antibiotic prescribing was observed. Future efforts in antibiotic stewardship may benefit from continued study of factors leading to this reduction and rebound in prescribing rates.

BACKGROUND/UNASSIGNED:Schedule design may contribute to successful completion of synchronous telehealth visits by video (versus audio-only). Clustering telehealth visits on schedules may minimize workflow inefficiencies. METHODS/UNASSIGNED:We analyzed data from 21 primary care sites in an urban public health care system from March 1 to September 30, 2022. We used linear regression to test for associations between the number of consecutive telehealth visits scheduled per clinicians' half-day sessions (1 to 9+) and the proportion of telehealth visits scheduled and, separately, completed as video (versus audio-only). RESULTS/UNASSIGNED:For each additional consecutive telehealth visit scheduled, there was a 6.85% [95% confidence interval 4.80 - 8.90%] increase in the absolute percentage of visits scheduled as video visits. For each additional consecutive telehealth visit scheduled, there was a 2.88% [0.59 - 5.18%] increase in the absolute percentage of visits completed as video visits. CONCLUSIONS/UNASSIGNED:Clustered telehealth visits are positively associated with scheduling and completion of telehealth visits by video.

BACKGROUND/UNASSIGNED:We looked to assess the odds of VTE subtypes among hospitalized individuals with IBD as compared to those without IBD. MATERIALS & METHODS/UNASSIGNED:Using the Nationwide Inpatient Sample database, we applied a multivariable regression analysis to compare the odds of primary VTE-related hospitalizations among individuals with and without IBD from 2016 to 2020, including deep venous thrombosis (DVT), pulmonary embolism (PE), portal vein thrombosis (PVT), Budd Chiari syndrome (BCS), renal vein thrombosis (RVT), and cerebral venous sinus thrombosis (CVST). RESULTS/UNASSIGNED:Overall, there were 15,565 primary VTE-related hospitalizations among individuals with IBD, as compared to 1,449,164 among individuals without IBD. Having IBD increased the odds for DVT (aOR = 1.34, 95%CI: 1.25-1.43), PVT (aOR = 3.16, 95%CI: 2.65-3.76), and CVST (aOR=1.45, 95%CI: 1.05-2.00), without significant increase in the odds of a PE, BCS, or RVT. Further, individuals with ulcerative colitis (UC) were at a higher risk for the majority of VTE-subtypes as compared to those with Crohn's disease (CD). Among individuals with a VTE-related hospitalization, the presence of IBD was not associated with increased mortality (aOR = 0.77, 95%CI: 0.40-1.50), but was associated with an increased length of stay (CD - 4.8 days, UC - 5.3 days, without IBD - 4.3 days, p<0.01). CONCLUSIONS/UNASSIGNED:Clinicians should retain a high index of suspicion when evaluating VTE-related symptoms among individuals with IBD, as the presence of IBD confers a higher risk of DVT, PVT and CVST related-hospitalizations, and longer stays as compared to individuals without IBD.

Sarcopenia, defined as a loss of muscle mass and function, is a physiologic factor that has been implicated as a predictor of adverse postoperative outcomes in many older adult populations. However, data related to sarcopenia in older adults with inflammatory bowel disease (IBD) remain limited. Older adults with IBD are particularly vulnerable to adverse postoperative outcomes, in part, due to muscle depletion from systemic inflammation, malnutrition, and reduced physical activity. However, few patients undergo routine muscle evaluation as a part of preoperative assessment. Moreover, cut-off values for measures of sarcopenia in the literature are modeled after non-IBD populations. The lack of standardized measures and values for sarcopenia in the IBD patient population has led to heterogenous findings and a paucity of preoperative risk stratification tools. Therefore, we aim to explore the scope of sarcopenia as a preoperative risk stratification tool among older adults with IBD.

Knowing when and where infected mosquitoes bite is required for estimating accurate measures of malaria risk, assessing outdoor exposure, and designing intervention strategies. This study combines secondary analyses of a human behaviour survey and an entomological survey carried out in the same area to estimate human exposure to malaria-infected Anopheles mosquitoes throughout the night in rural villages in south-eastern Tanzania. Mosquitoes were collected hourly from 6PM to 6AM indoors and outdoors by human landing catches in 2019, and tested for Plasmodium falciparum sporozoite infections using ELISA. In nearby villages, a trained member in each selected household recorded the whereabouts and activities of the household members from 6PM to 6AM in 2016 and 2017. Vector control use was high: 99% of individuals were reported to use insecticide-treated nets and a recent trial of indoor residual spraying had achieved 80% coverage. The risk of being bitten by infected mosquitoes outdoors, indoors in bed, and indoors but not in bed, and use of mosquito nets was estimated for each hour of the night. Individuals were mainly outdoors before 9PM, and mainly indoors between 10PM and 5AM. The main malaria vectors caught were Anopheles funestus sensu stricto and An. arabiensis. Biting rates were higher in the night compared to the evening or early morning. Due to the high use of ITNs, an estimated 85% (95% CI 81%, 88%) of all exposure in children below school age and 76% (71%, 81%) in older household members could potentially be averted by ITNs under current use patterns. Outdoor exposure accounted for an estimated 11% (8%, 15%) of infective bites in children below school age and 17% (13%, 22%) in older individuals. Maintaining high levels of ITN access, use and effectiveness remains important for reducing malaria transmission in this area. Interventions against outdoor exposure would provide additional protection.
