The Impact of Interpersonal Continuity of Primary Care on Health Care Costs and Use: A Critical Review.

PURPOSE: Interpersonal continuity has been shown to play an essential role in primary care's salutary effects. Amid 2 decades of rapid evolution in the health care payment model, we sought to summarize the range of peer-reviewed literature relating continuity to health care costs and use, information critical to assessing the need for continuity measurement in value-based payment design. METHODS: After comprehensively reviewing prior continuity literature, we used a combination of established medical subject headings (MeSH) and key words to search PubMed, Embase, and Scopus for articles published between 2002 and 2022 on "continuity of care" and "continuity of patient care," and payor-relevant outcomes, including cost of care, health care costs, cost of health care, total cost of care, utilization, ambulatory care-sensitive conditions, and hospitalizations for these conditions. We limited our search to primary care key words, MeSH terms, and other controlled vocabulary, including primary care, primary health care, family medicine, family practice, pediatrics, and internal medicine. RESULTS: Our search yielded 83 articles describing studies that were published between 2002 and 2022. Of these, 18 studies having a total of 18 unique outcomes examined the association between continuity and health care costs, and 79 studies having a total of 142 unique outcomes assessed the association between continuity and health care use. Interpersonal continuity was associated with significantly lower costs or more favorable use for 109 of the 160 outcomes. CONCLUSIONS: Interpersonal continuity today remains significantly associated with lower health care costs and more appropriate use. Further research is needed to disaggregate these associations at the clinician, team, practice, and system levels, but continuity assessment is clearly important to designing value-based payment for primary care.

Healthcare retention and clinical outcomes among adolescents living with HIV after transition from pediatric to adult care: a systematic review.

BACKGROUND: Adolescents living with HIV (ALWH) who transition from pediatric to adult care face several challenges that increase their risk of experiencing treatment interruptions and being lost to HIV care with resultant increased morbidity and mortality. To date, few studies have examined their outcomes post-healthcare transition (HCT), precluding the development and dissemination of evidence-based interventions aimed at retaining ALWH in HIV care both during and after HCT. We conducted a systematic review to synthesize the outcomes of ALWH post-HCT to provide suggestions for future directions. METHODS: We systematically searched several electronic databases through October 2019 using keywords for HIV, HCT and ALWH. We categorized studies by target population, country (i.e., upper-high income and low-middle income), study design (i.e., descriptive, mixed methods, quantitative), outcomes measured, and follow-up period. RESULTS: A total of 24 studies met inclusion criteria. Studies were categorized according to the following HCT outcomes: retention in HIV care post-HCT (n = 13), changes in CD4+ count and viral load post-HCT (n = 16), and mortality among ALWH post-HCT (n = 7). Most studies (n = 11) examining retention in HIV care indicated that more than 70% of ALWH were retained in care 1-2 years post-HCT while the remaining studies (n = 2) reported retention rates less than 55%. While studies indicated that CD4+ counts and viral loads tended to worsen during the first few years post-HCT, these differences were often not statistically significant. Among all ALWH who transitioned to adult care, a small proportion died within their first seven years post-HCT. Among qualitative studies, common themes included transition readiness (n = 6), provider-patient relationship in the adult clinic setting (n = 6), and concern about the adult clinic setting (n = 4). CONCLUSIONS: Transition outcomes were poorest for ALWH with unsuppressed viremia pre-HCT, suggesting that this subgroup of ALWH may need greater support from their treatment teams and caregivers during and post-HCT to improve clinical outcomes.

Interventions Targeting Expressive Communication in Adults With Autism Spectrum Disorders: A Systematic Review.

Purpose The aims of this systematic review are to (a) synthesize the literature on interventions targeting expressive communication in adults with autism spectrum disorder and (b) evaluate the effectiveness of the interventions. Method The literature search resulted in 7,196 articles. The research team used 2 reviewers and consensus for title/abstract review, full-text review, and quality review. To be included, studies had to (a) include at least 1 adult (18 years of age and above) with an autism spectrum disorder; (b) examine an intervention, treatment, or model of care; (c) provide outcome data related to expressive communication modalities/domains; (d) be experimental or quasi-experimental; and (e) be published in English. Twenty-two studies (14 single-case design and 8 group design), with a total of 256 participants and varied interventions and outcome variables, met criteria for inclusion. Effect sizes are presented for group design studies, and visual analysis results are outlined for single-case design studies. Results Examination of treatment effects in the included studies showed positive effects, overall; however, there was great variability between studies. Single-case design studies showed evidence of functional relations in all but 1 study, with most showing medium to large effects, as well as maintenance and generalization of gains. Group design studies showed a wide range of effects from near-zero to large effects. Differences in intervention strategies and durations, as well as in participant characteristics and outcome measures, presented barriers to aggregation. Conclusions This review highlights the need for increased high-quality research examining interventions targeting expressive communication in adults with autism spectrum disorder and also pinpoints interventions with potential for future study and use in this population.

HIV serostatus disclosure in the Democratic Republic of the Congo: a systematic review.

HIV status disclosure among people living with HIV/AIDS has been shown to have a number of both personal and public health benefits, but rates of HIV status disclosure remain low in many African countries, including the Democratic Republic of the Congo (DRC). This systematic review uses the Disclosure Process Model to examine the factors involved in serostatus disclosure and nondisclosure to various persons in the lives of people living with HIV/AIDS (PLWHA) in the DRC, as well as the specific outcomes of their disclosure or nondisclosure. MEDLINE/PubMed, Embase, Web of Science, Global Health, and PsycINFO were searched and research studies were included if: (i) the study discussed disclosure of HIV status; (ii) the study population included HIV-infected people in DRC; and (iii) the study was published in English. Fourteen articles met the inclusion criteria and were included in the study. Factors contributing to nondisclosure were generally associated with high stigma of HIV in adults and concern for emotional wellbeing when disclosing to HIV positive minors. Factors contributing to disclosure among adults were increased social support and religion. In disclosing to HIV positive minors, increasing age and health benefits were identified as approach goals that supported disclosure. The findings highlight the importance of understanding the avoidance and approach goals involved in HIV status disclosure among populations living in the DRC. Interventions and future research directed at increasing HIV disclosure among Congolese PLWHA should move beyond individual-level to consider multilevel factors including circumstantial social behaviors.

Clinical Inquiries: Does niacin decrease cardiovascular morbidity and mortality in CVD patients?

No. Niacin doesn't reduce cardiovascular disease (CVD) morbidity or mortality in patients with established disease (strength of recommendation [SOR]: A, meta-analyses of randomized controlled trials [RCTs] and subsequent large RCTs). Niacin may be considered as monotherapy for patients intolerant of statins (SOR: B, one well-done RCT).

A Scoping Review of Photovoice Research Among People With HIV.

We describe how Photovoice-a participatory method in which people express and share ideas via images-has been used in research with people living with HIV (PLWH). Four databases, reference lists, and journal tables of content were searched to identify peer-reviewed original research, in English, using Photovoice with a sample of PLWH, between 1994 and 2016. Of 1,898 citations identified, 22 studies were included. Studies included a mean of 18 (range 4-38) participants. Studies were of strong quality but lacked consistent procedures. Goals varied and projects included different combinations of introductory, photo training, ethics, group, individual, and exhibit sessions. Descriptions of the researcher-participant relationship were uneven. Photovoice allowed PLWH to inform research and practice priorities through their own visual perspectives. Continued use of Photovoice with PLWH is recommended with greater emphasis on consistent methods and detailed reporting; more studies should be undertaken resulting in actions or advocacy.

A Systematic Review of Safety and Immunogenicity of Influenza Vaccination Strategies in Solid Organ Transplant Recipients.

Immunogenicity from seasonal inactivated influenza vaccine (IIV) remains suboptimal in solid organ transplant recipients (SOTRs). We conducted a systematic review that compared the safety and immunogenicity of nonstandard influenza vaccination strategies with single-dose IIV in SOTRs. Booster doses and possibly high-dose (HD) influenza vaccination strategies seem to hold promise for improving vaccination immunogenicity in SOTRs. Administration of intradermal and MF59-adjuvanted trivalent IIV (IIV3) did not improve vaccine immunogenicity compared with single-dose intramuscular IIV. Alternative vaccine strategies were generally well tolerated; SOTRs who received HD, intradermal or adjuvanted IIV3 had a higher frequency of infection site reactions, while systemic adverse events were more frequent in SOTRs who received HD IIV3. Allograft rejection rates were similar in both groups. SOTRs should continue to receive standard-dose IIV annually in accordance with current recommendations, pending future studies to determine the optimal timing, frequency, and dosage of IIV using the booster-dose strategy.

A Systematic Review and Narrative Synthesis of Interventions for Parental Human Immunodeficiency Virus Disclosure.

INTRODUCTION: Disclosure of parental human immunodeficiency virus (HIV) infection to their children remains a difficult process for parents living with HIV (PLWH). In order to identify the best strategies to facilitate parental HIV disclosure, it is necessary to examine the efficacy of existing interventions designed to help PLWH parents with the disclosure process to their children. OBJECTIVES: To systematically review the efficacy of interventions designed to assist PLWH disclose their HIV status to their children. METHODS: We conducted a systematic review and narrative synthesis of interventions designed to assist PLWH disclose their HIV status to their children. MEDLINE/PubMed, PsycINFO, Embase, Global Health, and Web of Science were searched. RESULTS: Studies were eligible for inclusion if they evaluated an intervention for parental HIV disclosure. Five studies published between 2001 and 2015 met the inclusion criteria. The interventions were conducted in South Africa, China, and the United States. Three of the studies used two-arm randomized controlled trials, in which the intervention group was given enhanced care while the control group received standard care. Four of the five studies included a theoretically informed intervention and three were limited to mothers. Results showed that four of the interventions increased parental HIV disclosure. CONCLUSION: The findings suggest that parental HIV disclosure interventions are successful in assisting parents with the disclosure process and can be adapted in different cultural context. Future parental HIV disclosure interventions should include fathers in order to assist men with parental HIV disclosure.

Medical Student Teaching and Recruiting: 50 Years of Balancing Two Educational Aims.

BACKGROUND: Family medicine (FM) undergraduate medical educators have had two distinct missions, to increase the knowledge, skills, and attitudes of all students while also striving to attract students to the field of family medicine. A five decade literature search was conducted gathering FM curricular innovations and the parallel trends in FM medical student interest. Student interest in FM had a rapid first-decade rise to 14%, a second 1990's surge, followed by a drop to the current plateau of 8-9%. This falls far short of the 30-50% generalist benchmark needed to fill the country's health care needs. Curricular innovations fall into three periods: Charismatic Leaders & Clinical Exposures (1965-1978), Creation of Clerkships of FM (1979-1998) and Curricular Innovations (1998-present). There is good evidence that having a required third-year clerkship positively impacts student interest in the field, however there is little research regarding the recruitment impact of specific clerkship curricula. Other tools associated with student interest include programming geared towards primary care or rural training and extracurricular opportunities such as FM Interest Groups. Strategic plans to improve the primary care work force should focus funding and legislative efforts on effective methods such as: establishing and maintaining FM clerkships, admitting students with rural and underserved backgrounds or primary care interest, developing longitudinal primary care tracks, and supporting extracurricular FM activities. Rigorous research is needed to assess how best to utilize limited educational resources to ensure that all students graduate with a core set of FM competence as well as an increased FM matriculation.

Systematic review of mobile health behavioural interventions to improve uptake of HIV testing for vulnerable and key populations.

Introduction This systematic narrative review examined the empirical evidence on the effectiveness of mobile health (mHealth) behavioural interventions designed to increase the uptake of HIV testing among vulnerable and key populations. Methods MEDLINE/PubMed, Embase, Web of Science, and Global Health electronic databases were searched. Studies were eligible for inclusion if they were published between 2005 and 2015, evaluated an mHealth intervention, and reported an outcome relating to HIV testing. We also reviewed the bibliographies of retrieved studies for other relevant citations. The methodological rigor of selected articles was assessed, and narrative analyses were used to synthesize findings from mixed methodologies. Results A total of seven articles met the inclusion criteria. Most mHealth interventions employed a text-messaging feature and were conducted in middle- and high-income countries. The methodological rigor was moderate among studies. The current literature suggests that mHealth interventions can have significant positive effects on HIV testing initiation among vulnerable and key populations, as well as the general public. In some cases, null results were observed. Qualitative themes relating to the use of mobile technologies to increase HIV testing included the benefits of having low-cost, confidential, and motivational communication. Reported barriers included cellular network restrictions, poor linkages with physical testing services, and limited knowledge of appropriate text-messaging dose. Discussion MHealth interventions may prove beneficial in reducing the proportion of undiagnosed persons living with HIV, particularly among vulnerable and key populations. However, more rigorous and tailored interventions are needed to assess the effectiveness of widespread use.

A Systematic Review of HIV Serostatus Disclosure Among African Immigrants in Europe.

As the human immunodeficiency virus continues to devastate large parts of Africa, particularly the Sub-Saharan region, the number of immigrants migrating from these areas to European nations continues to grow. African men and women leave their countries for Europe because of armed conflicts, unemployment, or poverty. Thus, these migration patterns combined with newly contracted infections have resulted in a large and growing number of HIV-positive diagnoses among African immigrants living in Europe. Using the disclosure process model, this systematic review examines the reasons for HIV status disclosure and nondisclosure among African immigrants residing in Europe. PubMed, PsycINFO, Embase, Global Health, and Web of Science were searched. Bibliographies of retrieved studies were also reviewed for other relevant citations. Studies were eligible if they: (1) focused on HIV-positive immigrants from SSA residing in Europe; and (2) described or measured HIV status disclosure. Out of 166 articles found, a total of 17 articles and 1 brief report met the inclusion criteria. Factors such as stigma and social implications of disclosure contribute to avoidance goals leading to nondisclosure while approach goals or disclosure reasons were found to include health status and behaviors such as seeking support, and helping others. The findings highlight the importance of understanding the avoidance and approach goals involved in HIV status disclosure among African immigrants in Europe. Interventions and future research directed at increasing HIV disclosure among African immigrants in Europe should move beyond individual-level to consider multilevel factors including country-specific social behaviors.

Patient-Reported Outcome Instruments for Physical Symptoms Among Patients Receiving Maintenance Dialysis: A Systematic Review.

BACKGROUND: Patients with end-stage renal disease (ESRD) receiving dialysis have poor health-related quality of life. Physical symptoms are highly prevalent among dialysis-dependent patients and play important roles in health-related quality of life. A range of symptom assessment tools have been used in dialysis-dependent patients, but there has been no previous systematic assessment of the existing symptom measures' content, validity, and reliability. STUDY DESIGN: Systematic review of the literature. SETTINGS & POPULATION: Patients with ESRD on maintenance dialysis therapy. SELECTION CRITERIA FOR STUDIES: Instruments with 3 or more physical symptoms previously used in dialysis-dependent patients and evidence of validity or reliability testing. INTERVENTION: Patient-reported physical symptom assessment instrument. OUTCOMES: Instrument symptom-related content, validity, and reliability. RESULTS: From 3,148 screened abstracts, 89 full-text articles were eligible for review. After article exclusion and further article identification by reference reviews, 58 articles on 23 symptom assessment instruments with documented reliability or validity testing were identified. Of the assessment instruments, 43.5% were generic and 56.5% were ESRD specific. Symptoms most frequently assessed were fatigue, shortness of breath, insomnia, nausea and vomiting, and appetite. Instruments varied widely in respondent time burden, recall period, and symptom attributes. Few instruments considered recall periods less than 2 weeks and few assessed a range of symptom attributes. Psychometric testing was completed for congruent validity (70%), known-group validity (25%), responsiveness (30%), internal consistency (78%), and test-retest reliability (65%). Content validity was assessed in dialysis populations in 57% of the 23 instruments. LIMITATIONS: Consideration of physical symptoms only and exclusion of single symptom-focused instruments. CONCLUSIONS: The number of available instruments focused exclusively on physical symptoms in dialysis patients is limited. Few symptom-containing instruments have short recall periods, assess diverse symptom attributes, and have undergone comprehensive psychometric testing. Improved symptom-focused assessment tools are needed to improve symptom evaluation and symptom responsiveness to intervention among dialysis-dependent patients.

Non-publication of large randomized clinical trials: cross sectional analysis.

OBJECTIVE: To estimate the frequency with which results of large randomized clinical trials registered with ClinicalTrials.gov are not available to the public. DESIGN: Cross sectional analysis SETTING: Trials with at least 500 participants that were prospectively registered with ClinicalTrials.gov and completed prior to January 2009. DATA SOURCES: PubMed, Google Scholar, and Embase were searched to identify published manuscripts containing trial results. The final literature search occurred in November 2012. Registry entries for unpublished trials were reviewed to determine whether results for these studies were available in the ClinicalTrials.gov results database. MAIN OUTCOME MEASURES: The frequency of non-publication of trial results and, among unpublished studies, the frequency with which results are unavailable in the ClinicalTrials.gov database. RESULTS: Of 585 registered trials, 171 (29%) remained unpublished. These 171 unpublished trials had an estimated total enrollment of 299,763 study participants. The median time between study completion and the final literature search was 60 months for unpublished trials. Non-publication was more common among trials that received industry funding (150/468, 32%) than those that did not (21/117, 18%), P=0.003. Of the 171 unpublished trials, 133 (78%) had no results available in ClinicalTrials.gov. CONCLUSIONS: Among this group of large clinical trials, non-publication of results was common and the availability of results in the ClinicalTrials.gov database was limited. A substantial number of study participants were exposed to the risks of trial participation without the societal benefits that accompany the dissemination of trial results.

Clinical Inquiry: which treatments help women with reduced libido?

Several treatments produce modest, but statistically significant, clinical increases in sexual desire and function in women. The testosterone transdermal patch improves hypoactive sexual desire disorder (HSDD) in postmenopausal women.
