The Impact of Social Determinants of Maternal Mental Health in Marginalized Mothers.

Background: A deeper understanding of the key determinants of maternal mental health is important for improving care for women, especially women who are at an economic disadvantage. Objectives: To explore the associations of select social determinants: access, social support, and stress, with the onset of antepartum depression in low-income mothers. Participants: The Pregnancy Risk Assessment Monitoring System (PRAMS) is an ongoing, population-based surveillance system with selected data from 2016 to 2019, establishing a randomly selected sample of women with a recent live birth at most 4 months postdelivery, between 1,300 and 3,400 women per state (n ∼ 162,558). Methods: In this cross-sectional study, the phase 8 PRAMS was adapted to measure social support, access, stress, and their relationships with the onset of antepartum depression in low-income mothers. To assess low-income marginalization, a threshold was established based on income levels within 130% of the federal poverty level; antepartum (n ∼ 41,289). Results: The defined access, social support, and stress factors showed a statistically significant association with the onset of antepartum depression among low-income mothers. Of women in this sample, 22.6% indicated antepartum depression (p < 0.001; R2 = 0.066). Negative social support indicators were associated with an increased likelihood of antepartum depression; 3.71 increased odds of depression for abuse during pregnancy, and 0.79 decreased odds with positive acknowledgment of paternity. Access indicator terms showed an association with the decreased likelihood of antepartum depression through breastfeeding information support (Info from Baby Doc, odds ratio [OR] = 0.86), prenatal care utilization (12+ visits, OR = 0.82), and specific insurance type (insurance by job, OR = 0.82). All instances of stressful life events showed an increased likelihood of depression during pregnancy (for majority of stressful life events: OR >1.12). Conclusions: Economically marginalized mothers face unmet social and health care needs leading to poorer outcomes during pregnancy. These findings provide additional support for improved policy and public health efforts, such as assessment, education, and interventions, to decrease prevalence and improve treatment for antepartum depression among marginalized mothers.

Understanding multi-level barriers to medication adherence among adults living with sickle cell disease.

There is limited research that identifies and examines multi-level barriers to medication adherence among adults with Sickle Cell Disease (SCD); Identify multi-level barriers to medication adherence among adults with SCD; and Examine the relationship between multi-level barriers and medication adherence levels. A cross-sectional study included 130 adults (ages ≥ 18 years old) living with SCD who receive treatment/care from one of the 10 adult SCD clinics within the Networking California for sickle cell care initiative. Study measures included the medication adherence report scale (Professor Rob Horne), Beliefs about Medicine Questionnaire (Professor Rob Horne), and patient reported outcomes measurement information system. Participants reported barriers to medication adherence across 3 levels: Community-level barriers (e.g., COVID-19 pandemic); Institutional-level barriers (e.g., bad experiences with the health care system); and Individual-level barriers (e.g., beliefs and depression severity). Depression severity and patient concerns about SCD medication were inversely correlated with medication adherence (rs = -0.302, P < .001; rs = -0.341, P < .001 respectively). Patient beliefs about the necessity of SCD medication were insignificantly correlated with medication adherence (rs = 0.065, P = .464). Medication adherence was higher among patients who had fewer adherence barriers than multiple adherence barriers (Median medication adherence: fewer barriers = 22 vs multiple barrier = 20.50, P = .085), suggesting clinical significance although statistically insignificant. Identifying multi-level adherence barriers and examining their relationship with medication adherence will help develop targeted public health strategies to promote improved medication adherence and wellness among adults with SCD.

Risk Factors for Serious Psychological Distress among Pregnant Women and Mothers with Children less than One Year of Age: An Evaluation of National Health Interview Survey Data (1997-2016).

OBJECTIVE: This study examined individual factors associated with serious psychological distress (SPD) in mothers. METHODS: The study used National Health Interview Survey data (1997-2016), with analysis being restricted to pregnant women and non-pregnant mothers whose youngest child was 12 months old or younger. The Andersen framework, a reliable tool to study health services, was used to examine the effect of individual predisposing, enabling, and need factors. RESULTS: Of 5,210 women, 13.3% had SPD, as determined by the Kessler-6 scale. Compared to those without SPD, those with SPD were more likely to be 18 to 24 years old (39.0% vs. 31.7%; all P values < .001), never have been married (45.5% vs. 33.3%), not have completed high school (34.4% vs. 21.1%), have a family income below 100% of the federal poverty level (52.5% vs. 32.0%), and have public insurance (51.9% vs. 36.3%). Furthermore, women with SPD had a lower proportion of "excellent" health status (17.5% vs. 32.7%). Multivariable regression found that having any formal education was associated with a lower likelihood of perinatal SPD than was not completing high school. For example, the bachelor's degree odds ratio was 0.48 (95% CI: 0.30, 0.76). A receiver operator curve analysis revealed that individual predisposing factors (e.g. age, marital status, and education), accounted for more explained variation than did enabling or need factors. CONCLUSION: There are high levels of poor maternal mental health. Prevention and clinical services should focus on mothers with less than a high school education and those reporting poor physical health.

Comfort in seeking support from sexual violence prevention education health services among college women.

Objective: Explores racial differences of sexual violence-(SV) health service-(HS) outcomes among college women: (1) seeking support from a confidential-resource-(CR) and (2) reporting SV to the Title IX office. Participants: Data was collected from all ages of women (N = 583) and grade levels from one-large university on the Pacific-coast. Methods: Logistic-regression of HS outcomes were performed using the Fall 2016 American College Health Association-NCHA-II-survey. Results: The following variables increased the likelihood of women seeking support from the two health-services: (#1CR) relationship-status, race, and experiencing sexual-violence. WOC were 7x more likely to seek support if physically-assaulted, and WW were 3.9x more likely to seek support if a graduate student. (#2Title IX) year in school, physical-assault, and receiving prevention-education after the first-year in college. Overall, there were significant differences by race in the variables that influenced WW and WOC's comfort or likelihood to seek support. Conclusion: Colleges need to consider the disproportionate impact of SV on WOC.

Burden of Mental Illness among Primary HIV Discharges: A Retrospective Analysis of Inpatient Data.

Background: Empirical evidence demonstrates the substantial burden of mental illness among people living with HIV and AIDS (PLWHA). Current literature also notes the co-morbidity of these two illnesses and its impact on quality of life and mortality. However, little evidence exists on patient outcomes, such as hospital length of stay or post-discharge status. Methods: A retrospective analysis of National Inpatient Sample data was conducted. The study population was defined as discharges having a primary diagnosis of HIV based on International Classification of Disease, 10th Revision, Clinical Modification (ICD-10-CM) codes in primary diagnosis field. Clinical Classification Software (CCS) codes are used to identify comorbid mental illness. Length of stay was defined as number of days between hospital admission and discharge. Disposition (or post-discharge status) was defined as routine versus not routine. Patient and hospital characteristics were used as control variables. All regression analyses were survey-weighted and adjusted for control variables. Results: The weighted population size (N) for this study was 26,055 (n = 5211). Among primary HIV discharges, presence of any mental illness as a secondary discharge was associated with 12% higher LOS, when compared to a lack of such comorbidity (incidence rate ratio [IRR] = 1.12, 95% confidence interval [CI] = 1.05, 1.22, p < 0.01). Likewise, among primary HIV discharges, those with mental illness had a 21% lower routine disposition, when compared to those without any mental illness (OR = 0.79, 95% CI = 0.68, 0.91, p < 0.001). Conclusion: Our results highlight the need for improved mental health screening and coordinated care to reduce the burden of mental illness among HIV discharges.

Predictors of fall-related injuries due to common consumer products among elderly adult emergency department visits in the United States during 2007-2017.

Falls are the leading cause of injuries and death among the elderly in the United States (U.S.). This study examined unintentional fall related-injuries and potential associations between various consumer products. Data was analyzed from the National Electronic Injury Surveillance System (NEISS) of hospital emergency department (ED) visits for unintentional injuries among the elderly between 2007 and 2017. Multiple logistic regression was used to examine the association between consumer products and fall-related injury ED visits. A total of 537,703 injury-related ED visits were analyzed. Two-thirds of visits were fall-related. Of those, 33% were among those 85 years and older, 62.5% occurred at home, 37.6% had head trauma, and 28.7% resulted in hospitalization. Flooring materials accounted for 29.1% of injuries. Ladders were significantly associated with fall-related injuries (adjusted odds ratio [AOR] 5.48, 95% confidence interval [CI] 4.72-6.36), followed by flooring materials (AOR 3.09, 95% CI 2.60-3.67), and porches and balconies (AOR 2.61, 95% CI 2.30-2.96). Several common consumer products are associated with fall-related injuries among the elderly. Increased awareness and education are critical.

Antibiotic prophylaxis in the surgical management of miscarriage in low-income countries: a cost-effectiveness analysis of the AIMS trial.

BACKGROUND: There is ongoing debate on the clinical benefits of antibiotic prophylaxis for reducing pelvic infection after miscarriage surgery. We aimed to study the cost-effectiveness of antibiotic prophylaxis in the surgical management of miscarriage in low-income countries. METHODS: We did an incremental cost-effectiveness analysis using data from 3412 women recruited to the AIMS trial, a randomised, double-blind, placebo-controlled trial designed to evaluate the effectiveness of antibiotic prophylaxis in the surgical management of miscarriage in Malawi, Pakistan, Tanzania, and Uganda. Economic evaluation was done from a health-care-provider perspective on the basis of the outcome of cost per pelvic infection avoided within 2 weeks of surgery. Pelvic infection was broadly defined by the presence of clinical features or the clinically identified need to administer antibiotics. We used non-parametric bootstrapping and multilevel random effects models to estimate incremental mean costs and outcomes. Decision uncertainty was shown via cost-effectiveness acceptability frontiers. The AIMS trial is registered with the ISRCTN registry, number ISRCTN97143849. FINDINGS: Between June 2, 2014, and April 26, 2017, 3412 women were assigned to receive either antibiotic prophylaxis (1705 [50%] of 3412) or placebo (1707 [50%] of 3412) in the AIMS trial. 158 (5%) of 3412 women developed pelvic infection within 2 weeks of surgery, of whom 68 (43%) were in the antibiotic prophylaxis group and 90 (57%) in the placebo group. There is 97-98% probability that antibiotic prophylaxis is a cost-effective intervention at expected thresholds of willingness-to-pay per additional pelvic infection avoided. In terms of post-surgery antibiotics, the antibiotic prophylaxis group was US$0·27 (95% CI -0·49 to -0·05) less expensive per woman than the placebo group. A secondary analysis, a sensitivity analysis, and all subgroup analyses supported these findings. Antibiotic prophylaxis, if implemented routinely before miscarriage surgery, could translate to an annual total cost saving of up to $1·4 million across the four participating countries and up to $8·5 million across the two regions of sub-Saharan Africa and south Asia. INTERPRETATION: Antibiotic prophylaxis is more effective and less expensive than no antibiotic prophylaxis. Policy makers in various settings should be confident that antibiotic prophylaxis in miscarriage surgery is cost-effective.

A Randomized Trial of Prophylactic Antibiotics for Miscarriage Surgery.

BACKGROUND: Surgical intervention is needed in some cases of spontaneous abortion to remove retained products of conception. Antibiotic prophylaxis may reduce the risk of pelvic infection, which is an important complication of this surgery, particularly in low-resource countries. METHODS: We conducted a double-blind, placebo-controlled, randomized trial investigating whether antibiotic prophylaxis before surgery to complete a spontaneous abortion would reduce pelvic infection among women and adolescents in low-resource countries. We randomly assigned patients to a single preoperative dose of 400 mg of oral doxycycline and 400 mg of oral metronidazole or identical placebos. The primary outcome was pelvic infection within 14 days after surgery. Pelvic infection was defined by the presence of two or more of four clinical features (purulent vaginal discharge, pyrexia, uterine tenderness, and leukocytosis) or by the presence of one of these features and the clinically identified need to administer antibiotics. The definition of pelvic infection was changed before the unblinding of the data; the original strict definition was two or more of the clinical features, without reference to the administration of antibiotics. RESULTS: We enrolled 3412 patients in Malawi, Pakistan, Tanzania, and Uganda. A total of 1705 patients were assigned to receive antibiotics and 1707 to receive placebo. The risk of pelvic infection was 4.1% (68 of 1676 pregnancies) in the antibiotics group and 5.3% (90 of 1684 pregnancies) in the placebo group (risk ratio, 0.77; 95% confidence interval [CI], 0.56 to 1.04; P = 0.09). Pelvic infection according to original strict criteria was diagnosed in 1.5% (26 of 1700 pregnancies) and 2.6% (44 of 1704 pregnancies), respectively (risk ratio, 0.60; 95% CI, 0.37 to 0.96). There were no significant between-group differences in adverse events. CONCLUSIONS: Antibiotic prophylaxis before miscarriage surgery did not result in a significantly lower risk of pelvic infection, as defined by pragmatic broad criteria, than placebo.

Effect of the depot medroxyprogesterone acetate injectable and levonorgestrel implant on HIV genital shedding: a randomized trial.

OBJECTIVES: To assess the effect of the depot medroxyprogesterone acetate injectable (DMPA) and of the levonorgestrel (LNG) implant on genital HIV shedding among women receiving antiretroviral therapy (ART). METHODS: We randomized HIV-infected Malawian women to either DMPA or LNG implant from May 2014 to April 2015. HIV RNA was measured in cervicovaginal lavage (CVL) fluid and TearFlo Strips (TFS), and HIV DNA was measured in cells collected by CVL. We compared the frequency and magnitude of HIV genital shedding before and for 6 months after initiation of contraception and between arms among women receiving ART. We also compared genital HIV RNA levels obtained by sample type (TFS versus CVL). RESULTS: We analyzed data for 68 HIV-infected women receiving ART: 33 randomized to DMPA and 35 randomized to the LNG implant. Overall, HIV RNA was more often detectable and the quantity was higher on TFS compared with CVL. HIV DNA was detected very rarely in CVL cell samples (4 of 360 samples). The frequency of genital shedding and the genital HIV quantity did not increase after contraceptive initiation with either DMPA or LNG implant among women receiving ART. CONCLUSIONS: HIV-infected women receiving ART initiating contraception with either DMPA or LNG implant did not have any increase in genital HIV shedding during the first 6 months of contraceptive use. These findings are consistent with growing evidence that progestin contraception is not associated with increased HIV transmission risk from such women to their male partners. Consistent with other studies, genital HIV RNA detection was higher in TFS than in CVL fluid. IMPLICATIONS: In this randomized trial, neither DMPA nor the LNG implant, two of the most commonly used hormonal contraceptives among African women with HIV, was associated with increased genital HIV shedding in HIV-infected women receiving ART. These findings are reassuring and add to the currently limited information available for the highly effective contraceptive, LNG implant.

Prophylactic antibiotics to reduce pelvic infection in women having miscarriage surgery - The AIMS (Antibiotics in Miscarriage Surgery) trial: study protocol for a randomized controlled trial.

BACKGROUND: The estimated annual global burden of miscarriage is 33 million out of 210 million pregnancies. Many women undergoing miscarriage have surgery to remove pregnancy tissues, resulting in miscarriage surgery being one of the most common operations performed in hospitals in low-income countries. Infection is a serious consequence and can result in serious illness and death. In low-income settings, the infection rate following miscarriage surgery has been reported to be high. Good quality evidence on the use of prophylactic antibiotics for surgical miscarriage management is not available. Given that miscarriage surgery is common, and infective complications are frequent and serious, prophylactic antibiotics may offer a simple and affordable intervention to improve outcomes. METHODS: Eligible patients will be approached once the diagnosis of miscarriage has been made according to local practice. Once informed consent has been given, participants will be randomly allocated using a secure internet facility (1:1 ratio) to a single dose of oral doxycycline (400 mg) and metronidazole (400 mg) or placebo. Allocation will be concealed to both the patient and the healthcare providers. A total of 3400 women will be randomised, 1700 in each arm. The medication will be given approximately 2 hours before surgery, which will be provided according to local practice. The primary outcome is pelvic infection 2 weeks after surgery. Women will be invited to the hospital for a clinical assessment at 2 weeks. Secondary outcomes include overall antibiotic use, individual components of the primary outcome, death, hospital admission, unplanned consultations, blood transfusion, vomiting, diarrhoea, adverse events, anaphylaxis and allergy, duration of clinical symptoms, and days before return to usual activities. An economic evaluation will be performed to determine if prophylactic antibiotics are cost-effective. DISCUSSION: This trial will assess whether a single dose of doxycycline (400 mg) and metronidazole (400 mg) taken orally 2 hours before miscarriage surgery can reduce the incidence of pelvic infection in women up to 2 weeks after miscarriage surgery. TRIAL REGISTRATION: Registered with the ISRCTN (international standard randomised controlled trial number) registry: ISRCTN 97143849 . (Registered on April 17, 2013).

Schistosomiasis among obstetric fistula patients in Lilongwe, Malawi.

BACKGROUND: Schistosoma haematobium infection has been documented as an uncommon cause of vesicovaginal fistula (VVF) and can result in impaired wound healing of urogenital tissues. For these reasons, it could potentially be linked to an increased rate of obstetric fistula among women who experience obstructed labor and/or in a higher failure rate of fistula repair. Therefore, the primary objective of our study was to determine the prevalence of S. haematobium infection among women undergoing obstetric VVF repair in Lilongwe, Malawi. Our secondary objectives were to assess if S. haematobium infection could be a risk factor for obstetric fistula development or unsuccessful VVF repair in our patient population. METHODS: From July to October 2013, we conducted S. haematobium testing via urine microscopy on 96 patients undergoing obstetric VVF repair surgery at the Fistula Care Centre in Lilongwe, Malawi. RESULTS: The prevalence of S. haematobium infection among women undergoing obstetric VVF repair was 2% (n=2). Both women with S. haematobium had successful VVF repairs. CONCLUSIONS: Although S. haematobium has the potential to be a risk factor for obstetric VVF formation or unsuccessful VVF repair, it was uncommon among the women in our clinic with obstetric VVF.

Evaluation of a low-cost, low-power syringe pump to deliver magnesium sulfate intravenously to pre-eclamptic women in a Malawian referral hospital.

BACKGROUND: Magnesium sulfate is an affordable and effective treatment for pre-eclampsia and eclampsia. In settings where infusion pumps are not available to regulate the flow rate of intravenous delivery, healthcare providers must administer magnesium sulfate (MgSO4) via time-consuming and painful, large-volume intramuscular injections. As an alternative to costly commercially available syringe pumps, we developed AutoSyp, an accurate, low-cost, and low-powered syringe pump designed to meet the needs and constraints these low-resource settings. This paper describes results of a pilot study to evaluate the feasibility of using AutoSyp to administer MgSO4 intravenously to women suffering from pre-eclampsia at a referral hospital in Blantyre, Malawi. METHODS: AutoSyp was programmed to deliver MgSO4 following the Zuspan regimen to pregnant and post-partum women suffering from pre-eclampsia at Queen Elizabeth Central Hospital in Blatnyre, Malawi. Given the selection of either loading or maintenance dose on AutoSyp's user interface, the flow rate was automatically programmed to dispense 60 mL/h or 5 mL/h of 20% MgSO4 solution, respectively. During each treatment, the dispensed volume was automatically calculated by the device based on the plunger position and stored on a computer for accuracy analysis of the mean flow rate and total volume delivered. The clinical results for both the loading and maintenance dose administrations were compared to the device's accuracy during tests performed in the laboratory setting. RESULTS: Twenty-two women were enrolled in this study. In both the clinical and laboratory settings, the mean flow rate errors for the loading and maintenance dose infusions were under 2%. During 466 h of testing, the device sounded 129 occlusion alarms across 14 subjects. Of these, 71 alarms were false positives. CONCLUSION: Results of this study support the use of AutoSyp as a less painful and accurate means of MgSO4 administration in clinical environments that lack infusion systems. There were a large number of false alarms in the current system which will be addressed in future designs. AutoSyp maintains the comfort of intravenous MgSO4 administration, but unlike commercially available syringe pumps, it is capable of operating with a variety of syringe brands and sizes and requires no additional consumables. AutoSyp's appropriate design will benefit its implementation and sustained use in low-resource settings. TRIAL REGISTRATION: Trial registered prospectively on November 18, 2014 with ClinicalTrials.gov ( NCT02296931 ).

Differentiated Care Pathways for Antiretroviral Therapy Monitoring in Malawi: Expanding Viral Load Testing in Setting of Highly Prevalent Resistance.

We quantified resistance to first-line antiretroviral therapy among previously unmonitored patients in Malawi with viremia (≥1000 copies/mL). Ninety-five percent (n = 57/61) harbored nucleoside/tide reverse transcriptase inhibitor/non-nucleoside reverse transcriptase inhibitor resistance; resistance was more common comparing >2 (97%) versus ≤2 years (87%) on therapy. Immediate switch for persons retained in care may improve monitoring efficiency and maximize clinical outcomes.

Reflections on the first twenty-five years of the University of Malawi College of Medicine.

September 2016 marks 25 years since the College of Medicine of the University of Malawi was established. In this article we reflect on its conception, birth, adolescence, and youth. The contributions of multiple stakeholders are celebrated while being mindful of the ongoing efforts to consolidate past and current gains. For instance, the College of Medicine was, until recently, the only medical school in the country, but a new private medical school has just been opened in Lilongwe. International partnerships and wide-ranging resource mobilisation from both internal and international funders has been the hallmark of the growth and expansion of the Malawi College of Medicine. Further, the expanding needs for specialists in several clinical and non-clinical areas among the health professions calls for responsive strategies to address this and other human resources needs.

Long-term outcomes for women after obstetric fistula repair in Lilongwe, Malawi: a qualitative study.

BACKGROUND: Obstetric fistula affects a woman's life physically, psychosocially, and economically. Although surgery can repair the physical damage of fistula, the devastating consequences that affect a woman's quality of life may persist when she reintegrates into her community. This qualitative study assessed long-term outcomes among women who underwent obstetric fistula repair in Malawi. We explored three domains: overall quality of life before and after repair, fertility and pregnancy outcomes after repair, and understanding of fistula. METHODS: In-depth interviews were conducted in Chichewa with 20 women from seven districts across Central Malawi. All women were interviewed 1 to 2 years after surgical repair for obstetric fistula at the Fistula Care Centre in Lilongwe, Malawi. Interviews were independently coded and analyzed using content analysis. RESULTS: About half of women were married and nine of 20 women reported some degree of urinary incontinence. With the exception of relationship challenges, women's concerns before and after repair were different. Additionally, repair had resolved many of the concerns women had before repair. However, challenges, both directly and indirectly related to fistula, persisted. Improvements in quality of life at the individual level included feelings of freedom, confidence and personal growth, and improved income-earning ability. Interpersonal quality of life improvements included improved relationships with family and friends, reduced stigma, and increased participation with their communities. Nearly half of women desired future pregnancies, but many were uncertain about their ability to bear children and feared additional pregnancies could cause fistula recurrence. Most women were well informed about fistula development but myths about witchcraft and fear of delivery were present. Nearly all women would recommend fistula repair to other women, and many were advocates in their communities. CONCLUSIONS: Nearly all women believed their quality of life had improved at the individual and interpersonal levels since fistula repair, even among women who continued to have urinary incontinence. Contrary to other studies, women reported they were welcomed back by their communities and had limited challenges when reintegrating. Despite the overall improvements in quality of life, many continued to have relationship problems and were concerned about future fertility. These issues need to be further explored in other studies.

Characteristics of youth sexual and reproductive health and risky behaviors in two rural provinces of Cambodia.

BACKGROUND: The global number of youths has risen with a majority living in Southeast Asia. In Cambodia, rural youths often face difficult barriers to health, which include lack of sexual and reproductive health knowledge, information, and services. Risky behaviors are a threat to the health of many young people in Cambodia. METHODS: We studied a sample of 300 youths to describe sexual and reproductive health characteristics and risky behaviors in two rural provinces of Cambodia. Using a multi-staged sampling method, 30 villages were selected for interviewing. A peer-to-peer interviewing criterion was used that matched interviewer to interviewee based upon sex. Logistic regression models were used to compare risk between sexes and assess for associations between reproductive health variables, gender, youth attitudes, and risky youth social behaviors. RESULTS: A majority (90%) stated that a boy or girl should defer sex till marriage. A majority of youths (92%) also reported that they may or definitely will seek sexual and reproductive health services in the future. About 5.4% of youth had a prior sexual experience. Only 6.7% of youth reported having they traveled to a local health center, hospital or clinic to seek healthcare for a reproductive health problem. Overall, 27% reported alcohol use in prior 30 days. Relative to girls, boys were more likely to report alcohol use, going out late at night with friends, gambling, pornography use, gambling, and practicing risky behaviors with peers. Living with both parents and current school enrollment, had limited impact on rural youth's individual and social behaviors. CONCLUSION: Although there are favorable findings compatible with traditional Cambodian values and beliefs, the youth in this study are challenged with alcohol use, practicing risky behaviors with peers, and low condom use. Findings have implications for practice and policy to prevent substance abuse and improve outcomes for substance use, sexual and reproductive health.

Dried blood spots for viral load monitoring in Malawi: feasible and effective.

OBJECTIVES: To evaluate the feasibility and effectiveness of dried blood spots (DBS) use for viral load (VL) monitoring, describing patient outcomes and programmatic challenges that are relevant for DBS implementation in sub-Saharan Africa. METHODS: We recruited adult antiretroviral therapy (ART) patients from five district hospitals in Malawi. Eligibility reflected anticipated Ministry of Health VL monitoring criteria. Testing was conducted at a central laboratory. Virological failure was defined as >5000 copies/ml. Primary outcomes were program feasibility (timely result availability and patient receipt) and effectiveness (second-line therapy initiation). RESULTS: We enrolled 1,498 participants; 5.9% were failing at baseline. Median time from enrollment to receipt of results was 42 days; 79.6% of participants received results within 3 months. Among participants with confirmed elevated VL, 92.6% initiated second-line therapy; 90.7% were switched within 365 days of VL testing. Nearly one-third (30.8%) of participants with elevated baseline VL had suppressed (<5,000 copies/ml) on confirmatory testing. Median period between enrollment and specimen testing was 23 days. Adjusting for relevant covariates, participants on ART >4 years were more likely to be failing than participants on therapy 1-4 years (RR 1.7, 95% CI 1.0-2.8); older participants were less likely to be failing (RR 0.95, 95% CI 0.92-0.98). There was no difference in likelihood of failure based on clinical symptoms (RR 1.17, 95% CI 0.65-2.11). CONCLUSIONS: DBS for VL monitoring is feasible and effective in real-world clinical settings. Centralized DBS testing may increase access to VL monitoring in remote settings. Programmatic outcomes are encouraging, especially proportion of eligible participants switched to second-line therapy.

Measures of viral load using Abbott RealTime HIV-1 Assay on venous and fingerstick dried blood spots from provider-collected specimens in Malawian District Hospitals.

BACKGROUND: Viral suppression is a key indicator of antiretroviral therapy (ART) response among HIV-infected patients. Dried blood spots (DBS) are an appealing alternative to conventional plasma-based virologic testing, improving access to monitoring in resource-limited settings. However, validity of DBS obtained from fingerstick in field settings remains unknown. OBJECTIVES: Investigate feasibility and accuracy of DBS vs plasma collected by healthcare workers in real-world settings of remote hospitals in Malawi. Compare venous DBS to fingerstick DBS for identifying treatment failure. STUDY DESIGN: We recruited patients from ART clinics at two district hospitals in Malawi, collecting plasma, venous DBS (vDBS), and fingerstick DBS (fsDBS) cards for the first 149 patients, and vDBS and fsDBS only for the subsequent 398 patients. Specimens were tested using Abbott RealTime HIV-1 Assay (lower detection limit 40 copies/ml (plasma) and 550 copies/ml (DBS)). RESULTS: 21/149 (14.1%) had detectable viremia (>1.6 log copies/ml), 13 of which were detectable for plasma, vDBS, and fsDBS. Linear regression demonstrated high correlation for plasma vs. DBS (vDBS: ß=1.19, R(2)=0.93 (p<0.0001); fsDBS ß=1.20, R(2)=0.90 (p<0.0001)) and vDBS vs. fsDBS (ß=0.88, R(2)=0.73, (p<0.0001)). Mean difference between plasma and vDBS was 1.1 log copies/ml [SD: 0.27] and plasma and fsDBS 1.1 log copies/ml [SD: 0.31]. At 5000 copies/ml, sensitivity was 100%, and specificity was 98.6% and 97.8% for vDBS and fsDBS, respectively, compared to plasma. CONCLUSIONS: DBS from venipuncture and fingerstick perform well at the failure threshold of 5000 copies/ml. Fingerstick specimen source may improve access to virologic treatment monitoring in resource-limited settings given task-shifting in high-volume, low-resource facilities.
