Reporting on patients living with HIV "disengaging from care". Who is actually "lost to follow-up"?

Retention in care remains an important concern for health care providers. However, accurately identifying who is or is not retained in care can be problematic. Not all patients believed to be engaged in care are actually in care, and not all patients believed to be disengaged are truly disengaged. Identifying the status of individuals within populations is important for clinical, administrative and surveillance concerns. As part of the Linkage and Retention in Care Project at St Michael's Hospital in Toronto, Canada, we investigated the status of patients diagnosed with HIV. Detailed investigation determined who was actually Lost-to-Follow-Up (i.e., disengaged from care >12 months) and who had disengaged for known reasons. This approach determined more precisely who was currently followed in care and who was not, and to target efforts to contact and reengage patients more effectively. This study illustrates the importance of accurately monitoring populations enhancing disease management.

Reflection on the cause and avoidance of recurrent venous leg ulcers: An interpretive descriptive approach.

AIMS AND OBJECTIVES: To gain insight into the experience of recurrent venous leg ulcers from the individual's perspective and provide knowledge on potential risks of recurrence not previously investigated. BACKGROUND: Venous leg ulcers are a consequence of chronic venous disease and frequently recur. They are costly and can impact on physical and psychological health. Despite research suggesting the risk can be reduced through compression and lifestyle changes, recurrence rates are often high. This study provides an insight into individual's perceptions of the cause of their ulcers and how they try to avoid them. DESIGN: A qualitative design guided by the Chronic Illness Trajectory Model and Social Cognitive Theory. METHOD: A purposive sample of three males and four females were recruited from a community nursing clinic. Participants were ulcer free, had experienced at least two previous venous leg ulcers and could speak and comprehend English. An interpretive descriptive approach was taken using semi-structured interviews and thematic analysis. RESULTS: Three themes each containing three categories emerged: The Increasing Influence of the Recurring Wound on Mind and Body, Reflection on Past Experiences and Optimism in the Face of Adversity. Most participants reported traumatic injury and lower leg surgery triggered ulcer recurrence. Failure to replace compression stockings was also deemed a cause. Compression was reported essential, but some participants were unaware of the level they were wearing and how often it should be replaced. Other preventive activities included avoiding injury and securing immediate assistance if wounding occurred. CONCLUSION: Clinicians need to be aware that lower leg surgery may trigger recurrent venous ulceration and that individuals require ongoing emotional, physical and financial support throughout the trajectory of venous disease. The continued use of old compression stockings should be avoided and recurrence prevented by adoption of evidence-based practice rather than reflection on past experiences. RELEVANCE TO CLINICAL PRACTICE: This research raises the awareness of factors from the individual's perspective which can influence the recurrence of venous leg ulcers.

Complex care needs of patients with late-stage HIV disease: a retrospective study.

This retrospective chart review provides a profile of an emerging population of vulnerable HIV patients with complex comorbidities. Data were abstracted from all 83 patients admitted in 2008 to Casey House, a community-based hospital dedicated to supportive and palliative care for persons with HIV in Toronto, Canada. We describe patient characteristics, including medical and psychiatric conditions, and use a Venn diagram and case study to illustrate the frequency and reality of co-occurring conditions that contribute to the complexity of patients' health and health care needs. The mean age at admission was 49.2 years (SD10.5). Sixty-seven patients (80.7%) were male. Patients experienced a mean of 5.9 medical comorbidities (SD2.3) and 1.9 psychiatric disorders (lifetime Axis I diagnoses). Forty patients (48.2%) experienced cognitive impairment including HIV-associated dementia. Patients were on a mean of 11.5 (SD5.3) medications at admission; 74.7% were on antiretroviral medications with 55.0% reporting full adherence. Current alcohol and drug use was common with 50.6% reporting active use at admission. Our Venn diagram illustrates the breadth of complexity in the clients with 8.4% of clients living in unstable housing with three or more medical comorbidities and two or more psychiatric diagnoses. Comprehensive HIV program planning should include interventions that can flexibly adapt to meet the multidimensional and complex needs of this segment of patients. Researchers, policy-makers, and clinicians need to have greater awareness of overlapping medical, psychiatric and psychosocial comorbidities. Inclusion of the needs of these most vulnerable patients in the development of evidence-based guidelines is an important step for effectively treating, preventing, and planning for the future of HIV/AIDS care.

Increasing Treatment Rates for Hepatitis C in Primary Care.

BACKGROUND: Despite antiviral agents that can cure the disease, many individuals with Hepatitis C Virus (HCV) remain untreated. Primary care clinicians can play an important role in HCV treatment but often feel they do not have the requisite skills. METHODS: We implemented a population-based improvement intervention over 10 months to support treatment of HCV in a primary care setting. The intervention included a decision-support tool, education for clinicians, enhanced interprofessional team supports, mentorship, and proactive patient outreach. We used process and outcome measures to understand the impact on the proportion of patients who initiated treatment and achieved Sustained Virologic Response (SVR). We used physician focus groups and pharmacist interviews to understand the context and mechanisms influencing the impact of the intervention. RESULTS: Between December 2018 and June 2020, the percentage of HCV RNA positive patients who started treatment rose from 66.0% (354/536) to 75.5% (401/531) with 92.5% (371/401) of those starting treatment achieving SVR. Qualitative findings highlighted that the intervention helped raise awareness and confidence among physicians for treating HCV in primary care. A collaborative team environment, education, mentorship, and a decision-support tool integrated into the electronic record were all enablers of success although patient psychosocial complexity remained a barrier to engagement in treatment. CONCLUSION: A multifaceted primary care improvement initiative increased clinician confidence and was associated with an increase in the proportion of HCV RNA positive patients who initiated curative treatment.

Fish oil and indomethacin in combination potently reduce dyslipidemia and hepatic steatosis in LDLR(-/-) mice.

Fish oil (FO) is a potent anti-inflammatory and lipid-lowering agent. Because inflammation can modulate lipid metabolism and vice versa, we hypothesized that combining FO with cyclooxygenase inhibitors (COXIBs), well-known anti-inflammatory drugs, can enhance the anti-inflammatory and lipid-lowering effect of FO. LDLR(-/-) mice were fed a high-fat diet supplemented with 6% olive oil or FO for 12 wk in the presence or absence of indomethacin (Indo, 6 mg/l drinking water). FO reduced plasma total cholesterol by 30% but, in combination with Indo, exerted a greater decrease (44%). The reduction of liver cholesterol ester (CE) and triglycerides (TG) by FO (63% and 41%, respectively) was enhanced by Indo (80% in CE and 64% in TG). FO + Indo greatly increased the expression of genes modulating lipid metabolism and reduced the expression of inflammatory genes compared with control. The mRNA and/or protein expression of pregnane X receptor (PXR) and cytochrome P450 isoforms that alter inflammation and/or lipid metabolism are increased to a greater extent in mice that received FO + Indo. Moroever, the nuclear level of PXR is significantly increased in FO + Indo group. Combining FO with COXIBs may exert their beneficial effects on inflammation and lipid metabolism via PXR and cytochrome P450.

Examining the Utility of the HIV Disability Questionnaire (HDQ) in Clinical Practice: Perspectives of People Living with HIV and Healthcare Providers.

Our aim was to examine the utility of the HIV Disability Questionnaire (HDQ), a patient-reported outcome measure for use in clinical practice from the perspectives of people living with HIV (PLWH) and healthcare providers. We conducted a qualitative descriptive study. Fifteen PLWH and five healthcare providers participated in an interview, of which ten PLWH participated in a follow-up focus group discussion. The HDQ has value in clinical practice, including its role in assessing disability, facilitating communication, tailoring treatments, and guiding referrals. Strengths of the HDQ included its comprehensiveness, relevance of domains, and importance of specific items. Concerns related to length of the HDQ, the potential for some items to trigger emotional response, and negative connotations with the term 'disability.' Recommendations for HDQ implementation included the importance of score interpretability, shortening the questionnaire, and tailoring administration to the individual. Results suggest the HDQ possesses clinical utility with PLWH and healthcare providers.

The effects of a sacrococcygeal pilonidal sinus wound on activities of living: thematic analysis of participant interviews.

AIMS AND OBJECTIVE: To describe the effects sacrococcygeal pilonidal sinus wounds had on participants' activities of living. BACKGROUND: A sacrococcygeal pilonidal sinus commonly occurs in healthy young people and is associated with considerable morbidity and discomfort. Surgery is frequently required, and patients are often discharged home with large open wounds. Most research has addressed the technical aspects of surgery and treatment. DESIGN: An interpretive descriptive approach guided by The Model of Living framework. METHODS: Purposive sampling was used to recruit four women and seven men, age range 17-39 years, from a metropolitan hospital in NSW, Australia. Data were collected through semi-structured interviews that were audio-taped, transcribed verbatim and analysed using thematic analysis. RESULTS: Three themes and eight subthemes emerged from the analysis: (1) 'Adaption' included subthemes, learning to live with the wound, difficulty living with the wound and living life despite the wound; (2) 'Perception' embraced subthemes, embarrassment, lack of understanding and changed body image; and (3) 'Control' included subthemes, loss of control and gaining control. Participants whose pain was not managed, who were unprepared for the postoperative recovery at home or experienced delayed wound healing had most difficulty with activities of living. CONCLUSIONS: This research gives some insight into the pilonidal wound experience from the person's perspective. All activities of living were affected by the pilonidal sinus wound. The effect was variable and influenced by pain, embarrassment and a general lack of understanding about the condition and the care of the wound. The specific wound location was an underlying factor causing problems for participants. RELEVANCE TO CLINICAL PRACTICE: Individualised care will help in reducing discomfort and improving life experiences following surgery. Patients who are prepared for the postoperative recovery at home, have adequate analgesia and do not experience delayed wound healing are more likely to manage activities of living.

Health care utilization in medically complex people living with HIV before and after admission to an HIV-specific community facility: a pre-post comparison study.

BACKGROUND: People living with HIV and multiple comorbidities have high rates of health service use. This study evaluates system usage before and after admission to a community facility focused on HIV care. METHODS: We used Ontario administrative health databases to conduct a pre-post comparison of rates and costs of hospital admissions, emergency department visits, and family physician and home care visits among medically complex people with HIV in the year before and after admission to Casey House, an HIV-specific hospital in Toronto, for all individuals admitted between April 2009 and March 2015. Negative binomial regression was used to compare rates of health care utilization. We used Wilcoxon rank sum tests to compare associated health care costs, standardized to 2015 Canadian dollars. To contextualize our findings, we present rates and costs of health service use among Ontario residents living with HIV. RESULTS: During the study period, 268 people living with HIV were admitted to Casey House. Emergency department use declined from 4.6 to 2.5 visits per person-year (p = 0.02) after discharge from Casey House, and hospitalization rates declined from 1.4 to 1.1 admissions per person-year (p = 0.05). Conversely, home care visits increased from 24.3 to 35.6 visits per person-year (p = 0.01) and family physician visits increased from 18.3 to 22.6 visits per person-year (p < 0.001) in the year after discharge. These changes were associated with reduced overall costs to the health care system. The reduction in overall costs was not significant (p = 0.2); however, costs of emergency department visits (p < 0.001) and physician visits (p < 0.001) were significantly less. INTERPRETATION: Health care utilization by people with HIV was significantly different before and after admission to a community hospital focused on HIV care. This has implications for health care in other complex patient populations.

Strengths and Challenges of Implementing Physiotherapy in an HIV Community-Based Care Setting: A Qualitative Study of Perspectives of People Living with HIV and Healthcare Providers.

The needs of people living with HIV (PLWH) who have access to antiretroviral therapy have shifted from hospital to community care; however, little is known about physiotherapy within HIV community-based care. Our aim was to understand strengths and challenges of implementing physiotherapy within an interprofessional HIV day health program in Toronto, Ontario, Canada. We conducted a qualitative descriptive study using semi-structured interviews. Data were analyzed using inductive content analysis. Fifteen PLWH and 5 healthcare providers participated. Strengths included improved access to physiotherapy and fulfilling an unmet need for rehabilitation; a tailored approach to physiotherapy; co-location improved communication, coordination, and engagement in care; and improved health outcomes for PLWH (i.e. function, psychosocial outcomes, and quality of life). Challenges related to managing expectations; variable attendance at visits; and managing complex and diverse needs of PLWH. Results may be transferable to other community-based care settings that provide care for PLWH and complex multi-morbidity.

An initial map of chromosomal segmental copy number variations in the chicken.

BACKGROUND: Chromosomal segmental copy number variation (CNV) has been recently recognized as a very important source of genetic variability. Some CNV loci involve genes or conserved regulatory elements. Compelling evidence indicates that CNVs impact genome functions. The chicken is a very important farm animal species which has also served as a model for biological and biomedical research for hundreds of years. A map of CNVs in chickens could facilitate the identification of chromosomal regions that segregate for important agricultural and disease phenotypes. RESULTS: Ninety six CNVs were identified in three lines of chickens (Cornish Rock broiler, Leghorn and Rhode Island Red) using whole genome tiling array. These CNVs encompass 16 Mb (1.3%) of the chicken genome. Twenty six CNVs were found in two or more animals. Whereas most small sized CNVs reside in none coding sequences, larger CNV regions involve genes (for example prolactin receptor, aldose reductase and zinc finger proteins). These results suggest that chicken CNVs potentially affect agricultural or disease related traits. CONCLUSION: An initial map of CNVs for the chicken has been described. Although chicken genome is approximately one third the size of a typical mammalian genome, the pattern of chicken CNVs is similar to that of mammals. The number of CNVs detected per individual was also similar to that found in dogs, mice, rats and macaques. A map of chicken CNVs provides new information on genetic variations for the understanding of important agricultural traits and disease.

Antiretroviral Prescription Pick-up and Physician Follow-up After Hospital Discharge Among Medically Complex People With HIV.

In this study, only 22 of 206 (10.7%) socially marginalized individuals living with HIV and multiple comorbid conditions filled a prescription for antiretroviral therapy within 7 days of discharge from an HIV specialty hospital, despite comprehensive discharge planning. Additional interventions facilitating postdischarge continuity of care are required for this population.

The ART of conversation: feasibility and acceptability of a pilot peer intervention to help transition complex HIV-positive people from hospital to community.

OBJECTIVES: To pilot a peer-based intervention for people living with HIV who used substances, had challenges with antiretroviral adherence and would be discharged from hospital to community. STUDY DESIGN: A community-based, quasi-experimental pilot intervention study designed to assess feasibility, acceptability and connection to a community-based HIV organisation. SETTING: This study was conducted in Toronto, Canada, at Casey House (CH; hospital for people living with HIV) in collaboration with the AIDS Committee of Toronto (ACT; community-based HIV organisation). PARTICIPANTS: People living with HIV who were CH inpatient between 1 April 2017 and 31 March 2018, struggled with antiretroviral adherence, actively used substances and would be discharged to community were eligible. Forty people met criteria, 19 were approached by an inpatient nurse and 17 consented. Average age was 48.8 years (SD=11.4), 58.8% were male and participants averaged 7.8 physical and mental health comorbidities (SD=3.1). INTERVENTION: Titled 'The ART of Conversation', the three-pronged personalised intervention was developed through input from CH clients and ACT volunteers, all living with HIV. Intervention components were (a) predischarge goal-setting (adherence, substance use and self-identified goal) with the study nurse; (b) predischarge meeting with an HIV+ peer volunteer (PV) and (c) nine postdischarge phone calls between PV and participant, once per day for 3 days, then once per week for 6 weeks. PRIMARY OUTCOMES: Feasibility was measured through proportion of eligible participants recruited and PV availability. Acceptability was assessed through participant interviews at three times (preintervention, post-intervention and 6 weeks follow-up) and through PV call logs. Client records determined connection to ACT within the study timeframe. RESULTS: Twelve participants completed the intervention and nine connected with ACT. Predischarge goal-setting and PV meeting were both feasible and acceptable. Postdischarge phone calls were a challenge as half of completers missed at least one call. CONCLUSIONS: Although predischarge goal-setting and PV meeting were feasible, methods to maintain connection following discharge require further investigation.

The Lived Experience of the Hospital Discharge "Plan": A Longitudinal Qualitative Study of Complex Patients.

BACKGROUND: Transitions in care are a high-risk time for patients. Complex patients account for the largest proportion of healthcare costs but experience lower quality and discontinuity of care. The experiences of complex patients can be used to identify gaps in hospital discharge practices and design interventions to improve outcomes. METHODS: We used a case study approach with serial interviews and chart abstraction to explore the hospital discharge and transition experience over 6 weeks. Participants were recruited from a small hospital in Toronto that provides care to complex patients living with human immunodeficiency virus (HIV). Framework analysis was used to compare data across time-points and sources. RESULTS: Data were collected from 9 cases. Participants presented with complex medical and psychosocial challenges, including substance use (n = 9), mental health diagnoses (n = 8) and a mean of 5 medical comorbidities in addition to HIV. Data were analyzed and reported in 4 key themes: 1) social support; 2) discharge process and transition experience; 3) post-discharge follow-up; and 4) patient priorities. After hospital discharge, the complexity of participants' lives resulted in a change in priorities and subsequent divergence from the discharge plan. Despite the comprehensive discharge plans, with referrals designed to support their health and activities of daily living, participants experienced challenges with social support and referral uptake, resulting in a loss of stability achieved while in hospital. CONCLUSION: Further investigation and changes in practice are necessary to ensure that discharge plans for complex patients are realistic within the context of their lives outside of the hospital.

A systematic review of the relationship between internet use, self-harm and suicidal behaviour in young people: The good, the bad and the unknown.

BACKGROUND: Research exploring internet use and self-harm is rapidly expanding amidst concerns regarding influences of on-line activities on self-harm and suicide, especially in young people. We aimed to systematically review evidence regarding the potential influence of the internet on self-harm/suicidal behaviour in young people. METHODS: We conducted a systematic review based on an electronic search for articles published between 01/01/2011 and 26/01/2015 across databases including Medline, Cochrane and PsychInfo. Articles were included if: the study examined internet use by individuals who engaged in self-harm/ suicidal behaviour, or internet use clearly related to self-harm content; reported primary empirical data; participants were aged under 25 years. New studies were combined with those identified in a previous review and subject to data extraction, quality rating and narrative synthesis. RESULTS: Forty-six independent studies (51 articles) of varying quality were included. Perceived influences were: positive for 11 studies (38191 participants); negative for 18 studies (119524 participants); and mixed for 17 studies (35235 participants). In contrast to previous reviews on this topic studies focused on a wide range of internet mediums: general internet use; internet addiction; online intervention/treatment; social media; dedicated self-harm websites; forums; video/image sharing and blogs. A relationship between internet use and self-harm/suicidal behaviour was particularly associated with internet addiction, high levels of internet use, and websites with self-harm or suicide content. While there are negative aspects of internet use the potential for isolation reduction, outreach and as a source of help and therapy were also identified. CONCLUSIONS: There is significant potential for harm from online behaviour (normalisation, triggering, competition, contagion) but also the potential to exploit its benefits (crisis support, reduction of social isolation, delivery of therapy, outreach). Young people appear to be increasingly using social media to communicate distress, particularly to peers. The focus should now be on how specific mediums' (social media, video/image sharing) might be used in therapy and recovery. Clinicians working with young people who self-harm or have mental health issues should engage in discussion about internet use. This should be a standard item during assessment. A protocol for this review was registered with the PROSPERO systematic review protocol registry: (http://www.crd.york.ac.uk/prospero/display_record.asp?ID=CRD42015019518).

A cross-sectional study of malaria endemicity and health system readiness to deliver services in Kenya, Namibia and Senegal.

Despite good progress towards elimination, malaria continues to contribute substantially to the sub-Saharan African disease burden. Sustaining previous gains requires continued readiness to deliver malaria services in response to actual disease burden, which in turn contributes to health systems strengthening. This study investigates a health system innovation. We examined whether malaria prevalence, or endemicity, is a driver of health facility readiness to deliver malaria services. To estimate this association, we geo-linked cross-sectional facility survey data to endemicity data for Kenya, Namibia and Senegal. We tested the validity and reliability of the primary study outcome, the malaria service readiness index and mapped service readiness components in a geographic information system. We conducted a weighted multivariable linear regression analysis of the relationship between endemicity and malaria service readiness, stratified for urban or rural facility location. As endemicity increased in rural areas, there was a concurrent, modest increase in service readiness at the facility level [ß: 0.028; (95% CI 0.008, 0.047)], whereas no relationship existed in urban settings. Private-for-profit facilities were generally less prepared than public [ß: -0.102; (95% CI - 0.154, -0.050)]. Most facilities had the necessary supplies to diagnose malaria, yet availability of malaria guidelines and adequately trained staff as well as medicines and commodities varied. Findings require cautious interpretation outside the study sample, which was a more limited subset of the original surveys' sampling schemes. Our approach and findings may be used by national malaria programs to identify low performing facilities in malarious areas for targeted service delivery interventions. This study demonstrates use of existing data sources to evaluate health system performance and to identify within- and cross-country variations for targeted interventions.

Observations on the exoerythrocytic stages of different isolates of Plasmodium cynomolgi in hepatocytes of New World aotus and Saimiri monkeys.

Sporozoites of 3 isolates of Plasmodium cynomolgi dissected from the salivary glands of Anopheles dirus and Anopheles quadrimaculatus were injected intravenously into 9 New World monkeys. Liver stage parasites were demonstrated in all 9 animals; 7 of these animals also produced blood stages after prepatent periods of 9 to 23 days.

Decrease in circulating CD25(hi)Foxp3(+) regulatory T cells following vaccination with the candidate malaria vaccine RTS,S.

Regulatory T (Treg) cells have been shown in some cases to limit vaccine-specific immune responses and impact efficacy. Very little is known about the regulatory responses to the leading malaria vaccine candidate, RTS,S. The goal of this study was to begin to characterize the regulatory responses to the RTS,S vaccine. Using multi-parameter flow cytometry, we examined responses in 13 malaria naïve adult volunteers who received 2 doses of RTS,S given eight weeks apart. Five of these volunteers had previously received 3 doses of a candidate DNA-CSP vaccine, with the final dose given approximately one year prior to the first dose of the RTS,S vaccine. We found that the frequency of CD25(hi)Foxp3(+) Treg cells decreased following administration of RTS,S (p=0.0195), with no differences based on vaccine regimen. There was a concomitant decrease in CTLA-4 expression on CD25(hi)Foxp3(+) Treg cells (p=0.0093) and PD-1 levels on CD8(+) T cells (p=0.0002). Additionally, the frequency of anergic CTLA-4(+)CCR7(+) T cells decreased following vaccination. An inverse correlation was observed between the frequency of Plasmodium falciparum circumsporozoite protein (PfCSP)-specific IFN-γ and PfCSP-specific IL-10, as well as an inverse correlation between IL-10 induced by Hepatitis B surface antigen, the carrier of RTS,S, and PfCSP-specific IFN-γ, suggesting that immunity against the vaccine backbone could impact vaccine immunogenicity. These results have implications for future malaria vaccine design.
