Symptoms of emotional disorders and sociodemographic factors as moderators of dropout in psychological treatment: A meta-review

Objective: Dropout from psychological treatment is an important problem that substantially limits treatment effectiveness. A better understanding of this phenomenon, could help to minimize it. Therefore, we performed a systematic review of meta-analyses (MA) on dropout from psychological treatments to (1) determine the estimated overall dropout rate (DR) and (2) to examine potential predictors of dropout, including clinical symptoms (anxiety and depression) and sociodemographic factors. Method: A literature search of the PubMed PsycINFO, Embase, Scopus and Google Scholar databases was conducted. We identified 196 MAs on dropout from psychological treatment carried out primarily in adult patients or mixed samples (adults and children) between 1990 and 2022. Of these, 12 met all inclusion criteria. Two forest plots were created to visualize the DR and the relationship between DR and the disorder. Results: The DR ranged from 15.9% to 46.8% and was significantly moderated by symptoms of emotional disorders. The highest DR were observed in younger, unmarried patients, and those with lower educational and income levels. Conclusions: DR in patients undergoing psychological treatment is highly heterogeneous, but higher in individuals presenting symptoms of anxiety and/or depression, especially the latter. Given that high DR undermine the effectiveness of psychological interventions, it is clear that greater efforts are needed to reduce dropout, particularly among individuals with symptoms of emotional disorders.

Attrition rate and predictors of a monitoring mHealth application in adolescents with obesity.

BACKGROUND: Integrating mobile health (mHealth) into paediatric obesity treatment can provide opportunities for more personalized and lifetime treatment. However, high attrition rates pose a significant challenge. The current study attempts to better understand attrition by exploring (1) attrition rates of a monitoring mHealth application for usage over 14 days and (2) testing predictors of attrition in adolescents with obesity. METHODS: Participants were 69 adolescents between 12 and 16 years old who engaged in a multidisciplinary obesity treatment centre (either outpatient or inpatient) in two countries (Belgium and France). To assess the attrition rates, frequency distributions were used. To test the predictors of attrition, zero-inflated negative binomial regression was performed. RESULTS: Attrition rates were high, in the outpatient group, more than half of the participants (53.3%) used the app for only 0-7 days. In the inpatient group, this percentage was 24.1%. Only deficits in initiating (a component of executive functions) were a negative predictor of attrition, indicating that deficits in initiating lead to lower attrition rates. CONCLUSIONS: This study provides evidence for high attrition rates in mHealth interventions for adolescents with obesity and was the first to investigate psychological predictors of attrition to an mHealth monitoring tool in adolescents with obesity in treatment. Findings regarding predictors of attrition should be approached with caution due to the small sample size.

Predictors of psychotherapy dropout in patients with borderline personality disorder: A systematic review.

INTRODUCTION: Borderline personality disorder (BPD) is a highly debilitating psychiatric condition. Despite the expansion of new BPD specific forms of psychotherapy in the last few decades, high dropout rates have been reported in these treatments. Treatment discontinuation is associated with poor patient outcomes, inefficient resource utilization and the demoralization of healthcare providers. METHODS: In order to identify predictors of psychotherapy dropout among patients with BPD, a systematic search of Medline, the Cochrane Library, PsycInfo and PsycArticles was conducted. Studies included were randomized-controlled trials in which patients diagnosed with BPD were exposed to a therapeutic intervention consisted of an evidence-based psychotherapy. The quality of evidence in the studies was assessed through the use of revised Cochrane risk of bias tool. RESULTS: Six articles, incorporating four types of psychotherapy programmes, were included. Overall, the studies present low risk of attrition and reporting bias and unclear risk of selection, performance and detection bias. Patients with weaker therapeutic alliance scores and higher hostility presented with higher dropout rates. In contrast, better mindfulness skills and greater performance in specific neuropsychological domains, such as memory and executive control, were identified as predictive of lower risk of dropout. Sociodemographic variables and treatment history did not influence treatment retention. CONCLUSIONS: Factors that influence discontinuation should be taken into consideration in future treatment programmes, in an effort to optimize retention. Qualitative assessments of patients' reasons for dropping out may also help guide adjustments.

Absconding among admitted patients with bipolar affective disorder diagnosis in Uganda.

BACKGROUND: Hospitalization is often necessary for individuals with Bipolar affective Disorder (BAD) during severe manic or depressive episodes, as well as for stabilizing treatment regimens. However, a significant proportion of patients admitted for treatment of BAD abscond or leave the hospital without permission during their stay. In addition, patients managed for BAD may have unique characteristics that might force them into absconding. For example, the high prevalence of co-morbid substance use disorder - craving to use substances, suicidal behaviors - attempts to die by suicide, and cluster B personality disorders - characterized by impulsive acts. It is, therefore, essential to understand the factors contributing to absconding among patients with BAD, to facilitate designing strategies for preventing and managing this behavior. METHOD: This study was based on a retrospective chart review of the inpatients diagnosed with BAD at a tertiary psychiatry facility in Uganda from January 2018 to December 2021. RESULTS: Approximately 7.8% of those with BAD absconded from the hospital. The likelihood of absconding among those with BAD increased with the use of cannabis [adjusted odds ratio (aOR) = 4.00, 95% confidence interval (CI) = 1.22-13.09, p-value = 0.022] and having mood lability [aOR = 2.15, 95% CI = 1.10-4.21, p-value = 0.025]. However, receiving psychotherapy during the admission (aOR = 0.44, 95 CI = 0.26-0.74, p-value = 0.002) and treatment with haloperidol (aOR = 0.39, 95% CI = 0.18-0.83, p-value = 0.014) reduced the likelihood of absconding. CONCLUSION: Absconding among patients with BAD is common in Uganda. Those with symptoms of affective lability and those with comorbid cannabis use tend to abscond more, while those who receive haloperidol and psychotherapy are less likely to abscond.

Understanding dropout and non-participation in follow-up evaluation for the benefit of patients and research: evidence from a longitudinal observational study on patients with eating disorders.

Treatment outcomes in eating disorders (EDs) are still an open field for clinicians and researchers. Besides difficulties in egosyntonic-linked treatment engagements, dropout is one of the most crucial elements that cause a reduction in the treatment efficacy. Thus, the aim of this study is to evaluate factors that could contribute to high dropout rates and non-participation in follow-up evaluation in patients with ED. This study used a large sample of patients from a specialized ED ward and day hospital (DH). A sample of 428 individuals was recruited for this study. Psychological and demographic data were collected at the time of hospitalization and discharge from the facilities. These data were used to explore a possible link between dropout and follow-up non-participation. Specially, the random forest was used to rank demographic and psychological features in importance and evaluate the top results with regression analyses for statistical significance. A dropout rate of 12.14% during inpatient and DH treatment was found. Anger-hostility and general psychopathology were found to be predictors of dropout during treatment, while the duration of the hospitalization predicted non-participation at the six-month follow-up. Specific psychological features should be considered before and during treatments for patients with EDs to reduce dropout rates. The duration of the hospitalization should also be evaluated as a relevant healthcare element that could affect engagement and, accordingly, outcome.

Provider perceptions of their patients' dropout from trauma-focused therapy for PTSD in the U.S. Veterans Health Administration.

OBJECTIVE: Many patients who initiate prolonged exposure (PE) and cognitive processing therapy (CPT) do not complete a full course, although little is known about how providers view PE and CPT dropout among their own patients. METHOD: Semistructured interviews were conducted with providers (n = 29) in the Veterans Health Administration to understand each provider's experience of dropout by a specific patient whom they treated using PE or CPT. Content analysis was used to categorize perceptions of dropout as negative, somewhat negative, or not negative. Themes associated with somewhat or not negative views of dropout were identified via inductive coding. RESULTS: Fourteen percent of providers viewed their patient's dropout from PE or CPT as wholly negative, 38% as somewhat negative, and 48% as not a negative outcome. Themes associated with viewing dropout as something other than wholly negative included belief that the patient would not benefit from treatment if they were not ready, the importance of maintaining the therapeutic relationship, the view that trauma-focused therapy was not what the patient needed or that the patient could benefit from other approaches, the impression that the patient had made some gains, and that patients are responsible for treatment engagement and have the right to disengage. CONCLUSIONS: Providers' perceptions of dropout from PE or CPT for individual patients were rarely viewed as entirely negative. Research is needed to help providers determine when patient dropout is an undesirable outcome and when efforts to reengage patients in trauma-focused treatment are warranted.

Veterans' reasons for dropping out of prolonged exposure therapy across three delivery modalities: A qualitative examination.

Premature dropout from posttraumatic stress disorder treatment (PTSD) hinders treatment response. Studies have primarily used quantitative methodology to identify factors that contribute to Veterans' premature dropout, which has yielded mixed results. Qualitative methods provide rich data and generate additional hypotheses about why Veterans discontinue PTSD treatment. This study aimed to understand Veterans' reasons for dropping out of prolonged exposure therapy (PE) and to examine if there are differences in reasons for dropout between three delivery modalities: in-home, in-person (IHIP), office-based telehealth (OBT), or home-based telehealth (HBT). Twenty-two Veterans who dropped out of PE from a parent randomized clinical trial participated in individual qualitative interviews about potential contextual and individual factors related to discontinuation. Team-based coding was used to conduct open and focused coding. Themes were generated that described factors that influenced Veterans' dropout from PE and constant comparison was used to explore differences in reasons between the three modalities. Most Veterans had multiple reasons for dropping out and reasons were similar across delivery modalities with few differences. Practical barriers (e.g., scheduling difficulties), attitudes toward mental health providers and therapy (e.g., stigma), psychological and physical health factors (e.g., perceived worsening of symptoms, pain), and the therapeutic context (e.g., disliking aspects of PE) contributed to Veterans' decisions to drop out from PE. Veterans in OBT reported more types of practical barriers than Veterans in HBT and IHIP. These findings can help generate hypotheses about interventions that may promote engagement and future studies should continue to study how to reduce dropout.

The acceptability of cognitive analytic therapy (CAT): Meta-analysis and benchmarking of treatment refusal and treatment dropout rates.

AIM: To estimate treatment refusal and treatment dropout rates for cognitive analytic therapy (CAT) and then benchmark these rates against other psychotherapies. METHOD: PROSPERO registration CRD4202017081. Systematic searches found CAT treatment studies reporting treatment refusal and dropout rates. Studies were narratively and quantitatively synthesised in a proportional random-effects meta-analysis and moderator analyses were performed. Secondary analyses compared refusal and dropout rates for CAT versus other psychotherapies via direct comparisons in the original studies and via benchmarking these rates against other acceptability meta-analyses for other psychotherapies. RESULTS: Thirty-four CAT studies were included in the review. The treatment refusal rate was 15.35% (k = 9, 95% CIs 8.78-23.21). The treatment dropout rate was 18.69% (k = 34, 95% CI's 15.02-22.62). CAT generated significantly lower dropout rates relative to treatment comparators in the original studies (OR = 0.67; 95% CI 0.48-0.93). Country and younger age were significant moderators of dropout rates. CAT had a comparable treatment refusal rate and was towards the lower end of the dropout range when benchmarked against other psychotherapies. CONCLUSIONS: CAT as a brief and integrative psychotherapy for individuals presenting with typically complex psychological disorders appears a relatively acceptable intervention to patients.

Premature termination of the unified protocol for the transdiagnostic treatment of emotional disorders: The role of ambivalence towards change.

Ambivalence towards change is an expected, recurrent process in psychological change. However, the prolonged experience of ambivalence in psychotherapy contributes to client disengagement, which could result in treatment dropout. Considering the negative effects of premature termination of therapy and the convenience of the identification of clients who are at risk of dropping out before achieving good-outcome, the current study explored the predictive power of ambivalence for premature therapy termination using a multilevel time-backwards model (i.e., considering the session of the dropout as session zero and then modelling what occurred from the dropout until session 1). Participants included a total of 96 psychotherapy clients (38 dropouts) treated in a university-based clinic following the Unified Protocol for Transdiagnostic Treatment of Emotional Disorders. Multilevel modelling using a time-backwards model to analyse dropout data provided evidence of the predictive power of ambivalence evolution throughout treatment on the decision to prematurely discontinue treatment (p < .0001; R2 adj = .29). Specifically, good-outcome dropouts presented a decreasing ambivalence trend throughout treatment, whereas poor-outcome dropouts tended to experience the same levels of ambivalence before deciding to drop out (time × dropout; ß11 = .64, p = .014). Additionally, poor-outcome dropouts presented higher levels of ambivalence (ß01 = 9.92, p < .0001) in the last session. The results suggest that the pattern of client ambivalence towards change is a predictor of premature termination of therapy. Implications for clinical and research contexts are discussed.

Asistencia a un tratamiento para dejar de fumar con personas con trastorno por uso de sustancias / Smoking cessation treatment attendance among smokers with substance use disorders

Este estudio aporta evidencia para entender las tasas de no asistencia en fumadores con TUS asignados a un tratamiento de cese del tabaquismo. Los hallazgos indican que era más probable la no asistencia al tratamiento de los pacientes más jóvenes, en tratamiento por uso de cocaína, y con un menor número de días en tratamiento por uso de sustancias. Futuros ensayos de cesación tabáquica con esta población difícil de tratar deberían tener en cuenta la incorporación de estrategias para mejorar la asistencia y las tasas de retención. Esperamos que esta información sea útil para profesionales de la salud en su diseño e implementación de intervenciones para reducir las enfermedades relacionadas con el tabaquismo entre la población con TUS.

Tracking the dropout patients of neoadjuvant chemotherapy with locally advanced oral cavity cancer.

BACKGROUND: Patients with locally advanced oral cavity cancer sometimes stopped treatment after neoadjuvant chemotherapy. There are no guidelines of the management for these patients. Before designing clinical trials, we conducted this study to investigate their characteristics, reasons of dropout, and the follow-up information. METHODS: Medical records were consecutively reviewed of patients with locally advanced oral cavity cancer who underwent neoadjuvant chemotherapy from Jan 2017 to Dec 2019.Variables were compared between patients stopped treating after chemotherapy and completed treatments by student t-test and Chi-square test. Logistic regression model was used to calculate the odd rations of potential predictors of dropout. The dropout patients were followed up for reasons and results of their decision. RESULTS: A total of 171 patients were included with 23 not undergoing surgery after chemotherapy. The odd ratios of age over 65 and single marital status were 3.11 (95%CI: 1.1, 8.7) and 4.935 (95%CI: 1.5, 16.1), respectively, for the dropout. The median survival of patients without surgery was 7.4 months. Believing that chemotherapy would be effective and being afraid of the consequence of surgery were the main reasons of refusing surgery. CONCLUSIONS: The prognosis was poor of these dropout patients. Symptom relief and fear of surgery were the reasons of dropout. Age and marital status affected their decision. Clinical trials are needed to be designed for these patients.

Emergency Department Patients Who Leave Before Treatment Is Complete.

INTRODUCTION: Emergency department (ED) patients who leave before treatment is complete (LBTC) represent medicolegal risk and lost revenue. We sought to examine LBTC return visits characteristics and potential revenue effects for a large healthcare system. METHODS: This retrospective, multicenter study examined all encounters from January 1-December 31, 2019 at 18 EDs. The LBTC patients were divided into left without being seen (LWBS), defined as leaving prior to completed medical screening exam (MSE), and left subsequent to being seen (LSBS), defined as leaving after MSE was complete but before disposition. We recorded 30-day returns by facility type including median return hours, admission rate, and return to index ED. Expected realization rate and potential charges were calculated for each patient visit. RESULTS: During the study period 626,548 ED visits occurred; 20,158 (3.2%) LBTC index encounters occurred, and 6745 (33.5%) returned within 30 days. The majority (41.7%) returned in <24 hours with 76.1% returning in 10 days and 66.4% returning to index ED. Median return time was 43.3 hours, and 23.2% were admitted. Urban community EDs had the highest 30-day return rate (37.8%, 95% confidence interval, 36.41-39.1). Patients categorized as LSBS had longer median return hours (66.0) and higher admission rates (29.8%) than the LWBS cohort. There was a net potential realization rate of $9.5 million to the healthcare system. CONCLUSION: In our system, LSBS patients had longer return times and higher admission rates than LWBS patients. There was significant potential financial impact for the system. Further studies should examine how healthcare systems can reduce risk and financial impacts of LBTC patients.

"I just keep quiet about it and act as if everything is alright" - The cascade from trauma to disengagement among adolescents living with HIV in western Kenya.

INTRODUCTION: There are approximately 1.7 million adolescents living with HIV (ALHIV, ages 10 to 19) globally, including 110,000 in Kenya. While ALHIV experience poor retention in care, limited data exist on factors underlying disengagement. We investigated the burden of trauma among disengaged ALHIV in western Kenya, and its potential role in HIV care disengagement. METHODS: We performed in-depth qualitative interviews with ALHIV who had disengaged from care at two sites, their caregivers and healthcare workers (HCW) at 10 sites, from 2018 to 2020. Disengagement was defined as not attending clinic ≥60 days past a missed scheduled visit. ALHIV and their caregivers were traced through phone calls and home visits. Interviews ascertained barriers and facilitators to adolescent retention in HIV care. Dedicated questions elicited narratives surrounding traumatic experiences, and the ways in which these did or did not impact retention in care. Through thematic analysis, a conceptual model emerged for a cascade from adolescent experience of trauma to disengagement from HIV care. RESULTS: Interviews were conducted with 42 disengaged ALHIV, 34 caregivers and 28 HCW. ALHIV experienced a high burden of trauma from a range of stressors, including experiences at HIV disclosure or diagnosis, the loss of parents, enacted stigma and physical or sexual violence. A confluence of factors - trauma, stigma and isolation, and lack of social support - led to hopelessness and depression. These factors compounded each other, and resulted in complex mental health burdens, poor antiretroviral adherence and care disengagement. HCW approaches aligned with the factors in this model, suggesting that these areas represent targets for intervention and provision of trauma-informed care. CONCLUSIONS: Trauma is a major factor underlying disengagement from HIV care among Kenyan adolescents. We describe a cascade of factors representing areas for intervention to support mental health and retention in HIV care. These include not only the provision of mental healthcare, but also preventing or addressing violence, trauma and stigma, and reinforcing social and familial support surrounding vulnerable adolescents. In this conceptualization, supporting retention in HIV care requires a trauma-informed approach, both in the individualized care of ALHIV and in the development of strategies and policies to support adolescent health outcomes.

Subcutaneous Allergen Immunotherapy in Children: Real Life Compliance and Effect of COVID-19 Pandemic on Compliance.

BACKGROUND: Subcutaneous allergen immunotherapy (SCIT) is an effective treatment for allergic rhinitis, asthma, and venom allergy. Compliance is essential for SCIT to obtain maximal benefit as it is a long-term treatment. OBJECTIVES: This study aimed to determine the level of real-life SCIT compliance in pediatric patients and the associated factors. Additional aims were to determine how SCIT compliance was affected by the COVID-19 pandemic and why some patients dropped out SCIT. METHOD: Pediatric patients diagnosed with allergic rhinitis, allergic asthma, or venom allergy that received SCIT between September 2012 and July 2020 were analyzed. RESULTS: The study included 201 children (66.7% male) with a median (interquartile range) age of 12.8 years (9.4-15.2) at the time of the first SCIT injection. The overall compliance rate before COVID-19 pandemic was 86.1%. Short SCIT follow-up time and venom anaphylaxis were found to be risk factors for drop out. The leading causes of drop outs were moving to another city/country (32.1%), symptom improvement (17.8%), treatment ineffectiveness (14.2%), and adverse reactions (14.2%). Among the 108 patients that were still receiving SCIT during the COVID-19 pandemic, 31 (28.7%) dropped out the therapy. The most frequent reasons for drop-out were fear of being infected with COVID-19 (35.4%) and thinking that the AIT practise stopped due to COVID-19 pandemic (29%). Male gender and older age were found to be the independent risk factors for drop-out of SCIT. CONCLUSIONS: Real life compliance in children was found 13.9% and it was higher than adults. Nearly one-third of children dropped out during the CO-VID-19 pandemic. Male gender and older age are associated with SCIT drop-out during the COVID-19 pandemic.

Barriers and facilitators to use of a mobile HIV care model to re-engage and retain out-of-care people living with HIV in Atlanta, Georgia.

Novel strategies to re-engage and retain people living with HIV (PLWH) who are out of care are greatly needed. While mobile clinics have been used effectively for HIV testing and linkage, evidence guiding their use in providing HIV care domestically has been limited. To guide the development of a mobile HIV clinic (MHC) model as a strategy to re-engage and retain PLWH who are out of care, we aimed to explore stakeholder perceptions of barriers and facilitators to MHC implementation and use. From June 2019-July 2020, we conducted 41 in-depth interviews with HIV clinic providers, administrators, staff, legal authorities, and community advisory board members, PLWH, AIDS service organizations and city officials in Atlanta, Georgia, and domestic and international mobile health clinics to explore barriers and facilitators to use of MHCs. Interviews were transcribed, coded and thematically analysed. Barriers raised include potential for: breach of confidentiality with resulting heightened stigmatization, fractured continuity of care, safety concerns, staffing challenges, and low community acceptance of MHC presence in their locality. Participants provided suggestions regarding appropriate exterior design, location, timing, and co-delivery of non-HIV services that could facilitate MHC acceptance and address the concerns. In identifying key barriers and facilitators to MHC use, this study informs design and implementation of an MHC as a novel strategy for re-engaging and retaining PLWH who are out of care.

Research Attitudes Questionnaire scores predict Alzheimer's disease clinical trial dropout.

BACKGROUND: Missing data are a notable problem in Alzheimer's disease clinical trials. One cause of missing data is participant dropout. The Research Attitudes Questionnaire is a 7-item instrument that measures an individual's attitudes toward biomedical research, with higher scores indicating more favorable attitudes. The objective of this study was to describe the performance of the Research Attitudes Questionnaire over time and to examine whether Research Attitudes Questionnaire scores predict study dropout and other participant behaviors that affect trial integrity. METHODS: The Research Attitudes Questionnaire was collected at baseline and weeks 26 and 52 from each member of 119 participant/study partner dyads enrolled in a Phase 2, randomized, double-blind, placebo-controlled mild-to-moderate Alzheimer's disease clinical trial. Within-subject longitudinal analyses examined change in Research Attitudes Questionnaire scores over time in each population. Logistic regression analyses that controlled for trial arm and clustering in trial sites were used to assess whether baseline Research Attitudes Questionnaire scores predicted trial completion, study medication compliance, and enrollment in optional substudies. RESULTS: Participants and study partners endorsed statistically similar ratings on the Research Attitudes Questionnaire that were stable over time. Participants with baseline Research Attitudes Questionnaire scores above 28.5 were 4.7 (95% confidence interval = 1.01 to 21.95) times as likely to complete the trial compared to those with lower scores. Applying the same cutoff, baseline study partner Research Attitudes Questionnaire scores were similarly able to predict study completion (odds ratio = 4.2, 95% confidence interval = 1.71 to 10.32). Using a score cutoff of 27.5, higher participant Research Attitudes Questionnaire scores predicted study medication compliance (odds ratio = 5.85, 95% confidence interval = 1.34 to 25.54). No relationship was observed between Research Attitudes Questionnaire score and participation in optional substudies. CONCLUSION: This brief instrument that measures research attitudes may identify participants at risk for behaviors that cause missing data.

Withdrawal reasons of randomized controlled trials on type 2 diabetes: a systematic review.

PURPOSE: Type 2 diabetes mellitus (T2DM) is the subject of numerous randomized controlled trials (RCTs). The validity of RCTs may be threatened by attrition bias due to the discontinuation of the study. The aim of this systematic review is to evaluate the reasons of patient's withdrawal from these RCTs. METHODS: A systematic literature search on PubMed, Cochrane Library, Web of Science, and Scopus databases was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) flow diagram. The aim was to obtain all relevant blinded RCTs published before January 2017 in which the effectiveness of synthetic drugs, vitamins/minerals were compared to that of placebo or active control in T2DM. The quality of RCTs was assessed using the Jadad score. The frequency of withdrawal reasons was presented based on treatments with placebo/active control, national/international level of the studies, and publication year. Meta-analysis was not performed due to the heterogeneity. RESULTS: Overall, 1368 articles comprising of 640,780 subjects were included. In the majority of the RCTs (75.0%), the intervention and the placebo arms were compared. Most of the included studies (96%) were classified in the high-quality category (Jadad score≥3). The highest proportion of reported withdrawal cases was found in international studies, national RCTs conducted in Japan, and RCTs published in 2011. The withdrawal reasons were reported for 91,669 (63.75%) of the total 143,794 participants who had withdrawn from these studies. The main reported reasons were "adverse effects" (24.04%), "withdraw consent" (16.10%), and "missing data" (11.08%). Variations in the reported withdrawal reasons were based on the country or published year. RCTs with triple blinded design as well as those in which anti-hyperlipidemia and anti-obesity medications were applied, showed significantly higher probability of reported the withdrawal. CONCLUSION: High proportion of reported discontinuation in blinded RCTs on patients with T2DM was related to drug adverse effects. Overall, the total number and reason of drop out were unsatisfactory.

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.

Dropout of infertility treatments and related factors among infertile couples.

BACKGROUND: Dropout of infertility treatments is a global issue and many factors play role in this phenomenon. It is one of the most challenges in life of infertile couples. The purpose of this study was to determine dropout rate and related factors/reasons in the world and in Iran. METHODS: We will conduct a mixed method study with sequential exploratory design (systematic review, qualitative and quantitative phase). In the first stage a systematic review on dropout rate of infertility treatments and related factors will be done. In second stage (quantitative-qualitative study), a retrospective cohort study will be conducted on infertile couples to determine dropout rate of infertility treatments. The follow-up period to assess the discontinuation of treatment in patients, who have discontinued the treatment, will be considered 6 months after the treatment cessation. Data would be analyzed by descriptive statistics. We want to determine proportion and percentage of discontinuation rate among different groups with different causes of infertility. Then, we also will use Chi-square test to compare discontinuation rates among these groups. In qualitative section of second stage, semi-structured interviews would be performed with infertile female who had the history of infertility treatments failure. In this stage, participants will be selected using purposeful sampling method with maximum variation in terms of age, education, occupation, type of infertility, type of treatments, number of unsuccessful treatment and infertility duration. Data would be analyzed using conventional content analysis. DISCUSSION: Determining dropout rate and its related factors/reasons would be helpful for future studies to plan suitable interventions for supporting infertile couples. It also helps politicians to have a better understanding of infertility and its consequences on infertile couple's life. In today's world, infertility is a common phenomenon due to postponement of childbearing following the older age of marriage, tendency to reach higher educational level, economical problems and etc. Infertility brings many challenges and stresses to the individuals by itself and it is very hard to cope with. The problem gets worse, when it is associated with failure in treatments. Many of infertile couples cannot tolerate this failure and may decide to discontinue treatments before achieving pregnancy for ending many stressors which are associated with treatments. As we know, childbearing and having at least one child has important position in some societies such as Iranian culture; so ending the treatment before achieving optimal result may have some adverse consequences in the families such as divorce, remarriage, family conflicts, et. Absolutely many factors play role in dropout of infertility treatments, and many studies around the world have suggested many factors/reasons in dropout of infertility treatments, but there are still many gaps about this subject, especially among Iranian society. This study would be conducted in three consecutive stages, in the first stage; we will do a complete review of existing studies of the world to find out related factors/reasons of dropout in detail. In second stage, dropout rate of infertile couples (380 couples) after at least one unsuccessful cycle of treatment would be achieved by assessing medical records and telephone interview. Data of the first and second stage will help us to have better vision about the issue of dropout and would be used to construct a semi structured interview for the last stage. And finally in the third stage, reasons of dropout would be asked by an in depth interview from infertile couples. We hope the information from this study will help politicians better understand and plan for dropout of treatment.
