Short Communication: Late Refills During the First Year of Antiretroviral Therapy Predict Mortality and Program Failure Among HIV-Infected Adults in Urban Zambia

We evaluated the association of the number of late antiretroviral therapy (ART) refills with patient outcomes in a large public-sector human immunodeficiency virus treatment program in Lusaka, Zambia. Using pharmacy data routinely collected during 2004–2010, we calculated the number of late refills during the initial year of ART. We used multivariable Cox proportional hazard regression to examine the association between the number of late refills and death or program failure (i.e., death, loss to follow-up, or program withdrawal) >12 months after ART initiation, with and without stratification by the medication possession ratio (MPR) during the initial year of ART. Of 53,015 adults who received ART for ≥12 months (median follow-up duration, 86.1 months; interquartile range, 53.2–128.2 months), 26,847 (50.6%) had 0 late refills, 16,762 (31.6%) had 1, 6,505 (12.3%) had 2, and 2,901 (5.5%) had ≥3. Kaplan–Meier analysis revealed that ≥3 late refills was associated with a greater mortality risk than 1 and 2 late refills (p<0.001, by the log-rank test). The mortality risk was greater for patients with 2 late refills [adjusted hazard ratio (HR), 1.17; 95% confidence interval (CI), 0.99–1.38] or ≥3 late refills (adjusted HR, 1.51; 95% CI, 1.23–1.87), compared with that for patients with 0–1 late refills. Program failure was associated with ≥2 late refills. An MPR of <80% was associated with similar increases in mortality risk across late-refill strata. Monitoring late refills during the initial period of ART may help resource- and time-constrained clinics identify patients at risk for program failure

A Mobile Phone-Based, Community Health Worker Program for Referral, Follow-Up, and Service Outreach in Rural Zambia: Outcomes and Overview

Background: Mobile health (m-health) utilizes widespread access to mobile phone technologies to expand health services. Community health workers (CHWs) provide first-level contact with health facilities; combining CHW efforts with m-health may be an avenue for improving primary care services. As part of a primary care improvement project, a pilot CHW program was developed using a mobile phone-based application for outreach, referral, and follow-up between the clinic and community in rural Zambia. Materials and Methods: The program was implemented at six primary care sites. Computers were installed at clinics for data entry, and data were transmitted to central servers. In the field, using a mobile phone to send data and receive follow-up requests, CHWs conducted household health surveillance visits, referred individuals to clinic, and followed up clinic patients. Results: From January to April 2011, 24 CHWs surveyed 6,197 households with 33,304 inhabitants. Of 15,539 clinic visits, 1,173 (8%) had a follow-up visit indicated and transmitted via a mobile phone to designated CHWs. CHWs performed one or more follow-ups on 74% (n=871) of active requests and obtained outcomes on 63% (n=741). From all community visits combined, CHWs referred 840 individuals to a clinic. Conclusions: CHWs completed all planned aspects of surveillance and outreach, demonstrating feasibility. Components of this pilot project may aid clinical care in rural settings and have potential for epidemiologic and health system applications. Thus, m-health has the potential to improve service outreach, guide activities, and facilitate data collection in Zambia

Protocol-driven primary care and community linkages to improve population health in rural Zambia: the Better Health Outcomes through Mentoring and Assessment (BHOMA) project

Abstract Introduction Zambia’s under-resourced public health system will not be able to deliver on its health-related Millennium Development Goals without a substantial acceleration in mortality reduction. Reducing mortality will depend not only upon increasing access to health care but also upon improving the quality of care that is delivered. Our project proposes to improve the quality of clinical care and to improve utilization of that care, through a targeted quality improvement (QI) intervention delivered at the facility and community level. Description of implementation The project is being carried out 42 primary health care facilities that serve a largely rural population of more than 450,000 in Zambia’s Lusaka Province. We have deployed six QI teams to implement consensus clinical protocols, forms, and systems at each site. The QI teams define new clinical quality expectations and provide tools needed to deliver on those expectations. They also monitor the care that is provided and mentor facility staff to improve care quality. We also engage community health workers to actively refer and follow up patients. Evaluation design Project implementation occurs over a period of four years in a stepped expansion to six randomly selected new facilities every three months. Three annual household surveys will determine population estimates of age-standardized mortality and under-5 mortality in each community before, during, and after implementation. Surveys will also provide measures of childhood vaccine coverage, pregnancy care utilization, and general adult health. Health facility surveys will assess coverage of primary health interventions and measures of health system effectiveness. Discussion The patient-provider interaction is an important interface where the community and the health system meet. Our project aims to reduce population mortality by substantially improving this interaction. Our success will hinge upon the ability of mentoring and continuous QI to improve clinical service delivery. It will also be critical that once the quality of services improves, increasing proportions of the population will recognize their value and begin to utilize them

Association of the Implementation of the Patient-Centered Medical Home with Quality of Life in Patients with Multimorbidity

Thesis (Master's)--University of Washington, 2019Background: The patient-centered medical home (PCMH) has clinical benefits for chronic disease care, but the association with patient-reported outcomes such as health-related quality of life (HRQoL) is unexplored in patients with multimorbidity (two or more chronic diseases). Objective: To examine if greater clinic-level PCMH implementation was associated with higher HRQoL in multimorbid adults. Design: Retrospective cohort study. Participants: 22,095 multimorbid patients who received primary care at 944 Veterans Affairs (VA) clinics. Main Measures: Our exposure was the Patient Aligned Care Team Implementation Progress Index (PI2) for the clinic in 2012, a previously validated composite measure of PCMH implementation. Higher PI2 scores indicate better performance within eight PCMH domains. Outcomes were patient-reported HRQoL measured by the physical and mental component scores (PCS and MCS) from the Short Form-12 patient experiences survey in 2013-2014. Interaction of the outcomes with total hospitalizations and primary care visit count were also examined. Generalized estimating equations were used for main models after adjusting for patient and clinic characteristics. Results: The cohort average age was 68 years, mostly male (96%), and had an average of 4.4 chronic diagnoses. Compared to patients seen at the lowest scoring clinics for PCMH implementation, care in the highest scoring clinics was associated with a higher adjusted marginal mean PCS [42.3 (95% CI 41.3–43.4) vs. 40.3 (95% CI 39.1–41.5), P=0.01)], but a lower MCS [35.2 (95% CI 34.4–36.1) vs. 36.0 (95% CI 35.3–36.8), P=0.17]. Patients with prior hospitalizations seen in clinics with higher compared to lower PI2 scores had a 2.7 point greater MCS (95% CI 0.6–4.8; P=0.01). Conclusions: Multimorbid patients seen in clinics with greater PCMH implementation reported higher physical HRQoL, but lower mental HRQoL. The association between PCMH implementation and mental HRQoL may depend on complex interactions with disease severity and prior hospitalizations

Educational intervention to improve antibiotic knowledge at Kamuzu Central Hospital, Malawi

Background: Antibiotic resistance is a global issue that has the potential to significantly affect countries with limited antibiotic choices. At many government hospitals in Malawi, including Kamuzu Central Hospital (KCH), limited laboratory data and antibiotic options are barriers to providing appropriate antibiotics to patients. We aimed to design an educational intervention targeted to Malawian clinician trainees, including registrars, interns, and medical students, with the goal of improving their knowledge of appropriate antibiotic use based on available clinical information and Malawian guidelines. Methods: As part of an institutional partnership between the University of California—Los Angeles (UCLA) and KCH, an educational intervention was carried out at KCH in January, 2017. The intervention was designed and conducted by UCLA internal medicine-paediatrics residents, with supervision from a UCLA infectious disease specialist and KCH medical leadership. The intervention included a teaching session that reviewed common clinical infections, antibiotic options, duration of therapy, and detailed information regarding antibiotics commonly used in Malawi. Malawian trainees were supplied with an antibiotic prescribing pocket guide which summarised best practices from the Malawi Standard Treatment Guidelines, taking into account the hospital's drug formulary. Trainees were also provided with an algorithmic guide to aid decision-making for initiation of empirical antibiotics based on a patient's clinical presentation. Prior to the educational module, participants completed a multiple-choice survey to assess their baseline knowledge of appropriate antibiotic use for multiple case-based scenarios. A post-intervention survey was performed 2 weeks later, followed by a didactic session to review the correct answers for the cases and reinforce the intervention content. Findings: 33 pre-intervention surveys and 31 post-intervention surveys were completed. Of the 22 trainees who completed both surveys, the majority were medical students (n=16) and interns (n=4). Paired t-test analysis of the pre-test and post-test results showed a mean 17% increase in test scores (p<0·0001), which equates to an average of 2·4 more cases treated correctly. Interpretation: Brief, focused global health educational initiatives such as this may be able to provide local trainees with the knowledge to achieve best practices regarding antibiotic use. Ongoing educational initiatives are planned related to antimicrobial stewardship and other key clinical topics relevant to Malawi. Funding: None

Scripts and Strategies for Discussing Stopping Cancer Screening with Adults &gt; 75 Years: a Qualitative Study

BackgroundDespite guidelines recommending not to continue cancer screening for adults &gt; 75&nbsp;years old, especially those with short life expectancy, primary care providers (PCPs) feel ill-prepared to discuss stopping screening with older adults.ObjectiveTo develop scripts and strategies for PCPs to use to discuss stopping cancer screening with adults &gt; 75.DesignQualitative study using semi-structured interview guides to conduct individual interviews with adults &gt; 75&nbsp;years old and focus groups and/or individual interviews with PCPs.ParticipantsForty-five PCPs and 30 patients &gt; 75&nbsp;years old participated from six community or academic Boston-area primary care practices.ApproachParticipants were asked their thoughts on discussions around stopping cancer screening and to provide feedback on scripts that were iteratively revised for PCPs to use when discussing stopping mammography and colorectal cancer (CRC) screening.ResultsTwenty-one (47%) of the 45 PCPs were community based. Nineteen (63%) of the 30 patients were female, and 13 (43%) were non-Hispanic white. PCPs reported using different approaches to discuss stopping cancer screening depending on the clinical scenario. PCPs noted it was easier to discuss stopping screening when the harms of screening clearly outweighed the benefits for a patient. In these cases, PCPs felt more comfortable being more directive. When the balance between the benefits and harms of screening was less clear, PCPs endorsed shared decision-making but found this approach more challenging because it was difficult to explain why to stop screening. While patients were generally enthusiastic about screening, they also reported not wanting to undergo tests of little value and said they would stop screening if their PCP recommended it. By the end of participant interviews, no further edits were recommended to the scripts.ConclusionsTo increase PCP comfort and capability to discuss stopping cancer screening with older adults, we developed scripts and strategies that PCPs may use for discussing stopping cancer screening
