RESUMEN
OBJECTIVES: Behavioral and psychological symptoms of dementia (BPSD) are common and impart a significant burden to patients, caregivers, and the health system. However, there are few pharmacological options for treating BPSD. We conducted a systematic review of clinical trials examining the efficacy of anticonvulsants in BPSD. METHODS: We searched five electronic databases through January 2023, for randomized controlled trials and systematic reviews evaluating the efficacy of non-benzodiazepine anticonvulsants for the treatment of BPSD. We used the Cochrane risk of bias tool to ascertain the risk of bias in included trials. Because statistical pooling of results using meta-analysis was not feasible, we synthesized findings using the Cochrane Synthesis Without Meta-analysis reporting guidelines. RESULTS: We identified 12 studies, including randomized controlled trials (RCTs) and 1 systematic review. Five RCTs evaluating valproic acid were synthesized by a recent Cochrane review which concluded that this drug is likely ineffective for BPSD. We extracted data from 6 trials involving 248 individuals comparing non-benzodiazepine anticonvulsants to either placebo or risperidone. Four trials (n = 97 participants) evaluated carbamazepine, only one of which demonstrated an improvement in the Brief Psychiatric Rating Scale measuring agitation, hostility, psychosis, and withdrawal/depression (effect size: 1.13; 95% confidence interval [CI]: 0.54-1.73) relative to placebo. Adverse effects were more common in patients receiving carbamazepine (20/27; 74%) relative to placebo (5/24; 21%). There is low quality evidence that oxcarbazepine is likely ineffective and that topiramate may be comparable to risperidone. CONCLUSION: Anticonvulsants are unlikely to be effective in BPSD, although the quality of existing evidence is low.

COVID-19 associated public health measures and school closures exacerbated symptoms in some children and youth with attention-deficit hyperactivity disorder (ADHD). Less well understood is how the pandemic influenced patterns of prescription stimulant use. We conducted a population-based study of stimulant dispensing to children and youth ≤ 24 years old between January 1, 2013, and June 30, 2022. We used structural break analyses to identify the pandemic month(s) when changes in the dispensing of stimulants occurred. We used interrupted time series models to quantify changes in dispensing following the structural break and compare observed and expected stimulant use. Our main outcome was the change in the monthly rate of stimulant use per 100,000 children and youth. Following an initial immediate decline of 60.1 individuals per 100,000 (95% confidence interval [CI] - 99.0 to - 21.2), the monthly rate of stimulant dispensing increased by 11.8 individuals per 100,000 (95% CI 10.0-13.6), with the greatest increases in trend observed among females, individuals in the highest income neighbourhoods, and those aged 20 to 24. Observed rates were between 3.9% (95% CI 1.7-6.2%) and 36.9% (95% CI 34.3-39.5%) higher than predicted among females from June 2020 onward and between 7.1% (95% CI 4.2-10.0%) and 50.7% (95% CI 47.0-54.4%) higher than expected among individuals aged 20-24 from May 2020 onward. Additional research is needed to ascertain the appropriateness of stimulant use and to develop strategies supporting children and youth with ADHD during future periods of long-term stressors.

The COVID-19 pandemic was associated with increases in the prevalence of depression and anxiety among children and young adults. We studied whether the pandemic was associated with changes in prescription benzodiazepine use. We conducted a population-based study of benzodiazepine dispensing to children and young adults ≤ 24 years old between January 1, 2013, and June 30, 2022. We used structural break analyses to identify the pandemic month(s) when changes in prescription benzodiazepine dispensing occurred, and interrupted time series models to quantify changes in dispensing following the structural break and compare observed and expected benzodiazepine use. A structural break occurs where there is a sudden change in the trend of a time series. We observed an immediate decline in benzodiazepine dispensing of 23.6 per 100,000 (95% confidence interval [CI]: -33.6 to -21.2) associated with a structural break in April 2020, followed by a monthly decrease in the trend of 0.3 per 100,000 (95% CI: -0.74 to 0.14). Lower than expected benzodiazepine dispensing rates were observed each month of the pandemic from April 2020 onward, with relative percent differences ranging from - 7.4% (95% CI: -10.1% to - 4.7%) to -20.9% (95% CI: -23.2% to -18.6%). Results were generally similar in analyses stratified by sex, age, neighbourhood income quintile, and urban versus rural residence. Further research is required to understand the clinical implications of these findings and whether these trends were sustained with further follow-up.
RESUMEN
BACKGROUND: Hepatitis C is curable with direct-acting antivirals (DAAs). However, treatment uptake remains low among marginalized populations such as people who inject drugs. We sought to understand challenges to treatment uptake with DAAs among people living with hepatitis C and compare treatment experiences between people who do and do not inject prescription and/or unregulated drugs. METHODS: We conducted a qualitative study using focus groups with 23 adults aged 18 years and over who completed DAA treatment or were about to begin such treatment at the time of the study. Participants were recruited from hepatitis C treatment clinics across Toronto, Ontario. We drew upon stigma theory to interpret participants' accounts. RESULTS: Following analysis and interpretation, we generated five theoretically-informed themes characterizing the experiences of individuals accessing DAAs: "being 'worthy' of the cure", "spatially enacted stigma", "countering social and structural vulnerability: the importance of peers", "identity disruption and contagion: attaining a 'social cure'" and "challenging stigma with population-based screening". Overall, our findings suggest that structural stigma generated and reproduced through healthcare encounters limits access to DAAs among people who inject drugs. Peer-based programs and population-based screening were proposed by participants as mechanisms for countering stigma within health care settings and 'normalizing' hepatitis C among the general population. CONCLUSIONS: Despite the availability of curative therapies, access to such treatment for people who inject drugs is limited by stigma enacted in and structured within healthcare encounters. Developing novel, low-threshold delivery programs that remove power differentials and attend to the social and structural determinants of health and reinfection are needed to facilitate further scale up of DAAs and support the goal of eradicating hepatitis C as a public health threat.

BACKGROUND: In February 2018, Canada's National Advisory Committee on Immunization (NACI) recommended antenatal tetanus-diphtheria-acellular pertussis (Tdap) immunization in every pregnancy regardless of previous Tdap immunization history. We examined the impact of the NACI recommendation on rates of infant pertussis in Ontario, Canada. METHODS: We conducted a population-based time-series study of all live births in Ontario between August 1, 2011 and February 28, 2020. We used interventional autoregressive integrated moving average models to examine the impact of the NACI recommendation on monthly rates of pertussis among infants ≤ 3 months of age. RESULTS: We observed 675 incident cases of pertussis among 1,368,024 infants 3 months of age or less between August 2011 and February 2020. The average monthly percent change in infant pertussis during the period up to and including publication of the NACI guidance and the period following publication were 0.0% (95% CI: -0.4-0.3%) and - 0.8% (95% CI -2.3% to -0.1%), respectively. Following interventional ARIMA modelling, publication of the NACI guidance was not associated with a statistically significant decrease in the monthly pertussis incidence trend (-0.67 cases per 100,000 infants; p = 0.73). CONCLUSION: Publication of national recommendations for antenatal Tdap immunization in every pregnancy did not significantly reduce infant pertussis rates. This may reflect the persistently low rate of antenatal vaccination following publication of the recommendations. Expanding the scope of practice of allied health care providers to include antenatal Tdap immunization and patient education regarding antenatal pertussis immunization should be considered to further optimize uptake of vaccination.

OBJECTIVE: Stimulants are first-line pharmacotherapy for individuals with attention-deficit hyperactivity disorder. However, disparities in drug coverage may contribute to inequitable treatment access. In January 2018, the government of Ontario, Canada, implemented a publicly-funded program (OHIP+) providing universal access to medications at no cost to children and youth between the ages of 0 and 24. In April 2019, the program was amended to cover only children and youth without private insurance. We studied whether these policy changes were associated with changes in prescription stimulant dispensing to Ontario children and youth. METHODS: We conducted a population-based observational natural experiment study of stimulant dispensing to children and youth in Ontario between January 2013 and March 2020. We used interventional autoregressive integrated moving average models to estimate the association between OHIP+ and its subsequent modification with stimulant dispensing trends. RESULTS: The implementation of OHIP+ was associated with a significant immediate increase in the monthly rate of stimulant dispensing of 53.6 individuals per 100,000 population (95% confidence interval [CI], 36.8 to 70.5 per 100,000) and a 14.2% (95% CI, 12.8% to 15.6%) relative percent increase in stimulant dispensing rates between December 2017 and March 2019 (1198.6 vs. 1368.7 per 100,000 population). The April 2019 OHIP+ program amendment was associated with an increase in monthly stimulant dispensing trends of 10.2 individuals per 100,000 population (95% CI, 5.0 to 15.5), with rates increasing 7.5% (95% CI, 6.2% to 8.7%) between March 2019 and March 2020 (1368.7 vs. 1470.8 per 100,000 population). These associations were most pronounced among males, children and youth living in the highest income neighbourhoods and individuals aged 20 to 24. CONCLUSION: A publicly-funded pharmacare program was associated with more children and youth being dispensed stimulants.

BACKGROUND: Population-based research examining geographic variability in psychotropic medication dispensing to children and youth and the sociodemographic correlates of such variation is lacking. Variation in psychotropic use could reflect disparities in access to non-pharmacologic interventions and identify potentially concerning use patterns. METHODS: We conducted a population-based study of all Ontario residents aged 0 to 24 years who were dispensed a benzodiazepine, stimulant, antipsychotic or antidepressant between January 1, 2018, and December 31, 2018. We conducted small-area variation analyses and identified determinants of dispensing using negative binomial generalized estimating equation models. RESULTS: The age- and sex-standardized rate of psychotropic dispensing to children and youth was 76.8 (range 41.7 to 144.4) prescriptions per 1000 population, with large variation in psychotropic dispensing across Ontario's census divisions. Males had higher antipsychotic [rate ratio (RR) 1.40; 95% confidence interval (CI) 1.36 to 1.44) and stimulant (RR 1.75; 95% CI 1.70 to 1.80) dispensing rates relative to females, with less use of benzodiazepines (RR 0.85; 95% CI 0.83 to 0.88) and antidepressants (RR 0.81; 95% CI 0.80 to 0.82). Lower antipsychotic dispensing was observed in the highest income neighbourhoods (RR 0.72; 95% CI 0.70 to 0.75) relative to the lowest. Benzodiazepine (RR 1.12; 95% CI 1.01 to 1.24) and stimulant (RR 1.11; 95% CI 1.01 to 1.23) dispensing increased with the density of mental health services in census divisions, whereas antipsychotic use decreased (RR 0.82; 95% CI 0.73 to 0.91). The regional density of child and adolescent psychiatrists and developmental pediatricians (RR 1.00; 95% CI 0.99 to 1.01) was not associated with psychotropic dispensing. CONCLUSION: We found significant variation in psychotropic dispensing among young Ontarians. Targeted investment in regions with long wait times for publicly-funded non-pharmacological interventions and novel collaborative service models may minimize variability and promote best practices in using psychotropics among children and youth.

BACKGROUND: In January 2018, the Government of Ontario, Canada, initiated a universal pharmacare program (OHIP+) for all individuals aged 24 years and younger. In April 2019, the program was amended to cover only children and youth without private insurance. Because benzodiazepines are commonly prescribed to children and youth despite their potential hazards, we examined whether changes in publicly-funded drug coverage influenced benzodiazepine dispensing trends in this demographic. METHODS: We conducted a population-based natural experiment study of benzodiazepine dispensing to children and youth in Ontario between January 2013 and March 2020. We used interventional autoregressive integrated moving average models to estimate the impact of OHIP + and its subsequent modification on these trends. RESULTS: The implementation of OHIP + was associated with an immediate increase in the monthly rate of benzodiazepine dispensing of 12.9 individuals per 100,000 population (95% confidence interval [CI]; 7.5 to 18.3 per 100,000). Benzodiazepine dispensing rates rose from 214.2 to 241.5 per 100,000 from December 2017 to March 2019, a 12.8% (95% CI 9.6-16.0%) increase. In stratified analyses, increases were most pronounced among females, children and youth living in the lowest income neighbourhoods and individuals aged 20 to 24. The April 2019 modification to OHIP + was not associated with changes in monthly benzodiazepine dispensing trends (0.39 individuals per 100,000; 95% CI -1.3 to 2.1 per 100,000). However, rates remained elevated relative to the period preceding OHIP + implementation. CONCLUSIONS: Implementation of a publicly-funded pharmacare program resulted in more children and youth being prescribed benzodiazepines.

BACKGROUND: Accidental acetaminophen overdoses are associated with substantial morbidity and health care costs. In Canada, updated labelling standards were implemented in October 2009 and September 2016, with the intent of communicating risks of overdose and facilitating product identification and safe use, respectively. Full compliance with the 2016 standards was expected by March 2018. We sought to explore whether these changes affected rates of hospital admission for accidental acetaminophen overdose. METHODS: We conducted a population-based study of hospital admissions for accidental acetaminophen overdose in 9 Canadian provinces and 3 Canadian territories between Apr. 1, 2014, and Mar. 31, 2020. We used interventional autoregressive integrated moving average (ARIMA) models to evaluate the impact of the updated labelling standards on rates of hospital admission for accidental acetaminophen overdose. In secondary analyses, we studied intensive care unit (ICU) admissions and hospital admissions for accidental acetaminophen overdose involving opioids. RESULTS: Monthly rates of hospital admission for accidental acetaminophen overdose were essentially unchanged over the study period (0.21 and 0.22 cases per 100 000 population in April 2004 and March 2020, respectively). We found no association between changing labelling standards and trends in rates of hospital admission for accidental acetaminophen overdose (October 2009 p = 0.2, September 2016 p = 0.7 and March 2018 p = 0.2). Similarly, labelling changes did not have an impact on admissions involving ICU admission and concomitant opioid poisoning. INTERPRETATION: Modifications to product labels did not reduce the rate of acetaminophen-related harm. Additional measures to reduce the burden of accidental acetaminophen overdose are required.

BACKGROUND: London InterCommunity Health Centre (LIHC) launched a safer opioid supply (SOS) program in 2016, where clients are prescribed pharmaceutical opioids and provided with comprehensive health and social supports. We sought to evaluate the impact of this program on health services utilization and health care costs. METHODS: We conducted an interrupted time series analysis of London, Ontario, residents who received a diagnosis of opioid use disorder (OUD) and who entered the SOS program between January 2016 and March 2019, and a comparison group of individuals matched on demographic and clinical characteristics who were not exposed to the program. Primary outcomes were emergency department (ED) visits, hospital admissions, admissions for infections and health care costs. We used autoregressive integrated moving average (ARIMA) models to evaluate the impact of SOS initiation and compared outcome rates in the year before and after cohort entry. RESULTS: In the time series analysis, rates of ED visits (-14 visits/100, 95% confidence interval [CI] -26 to -2; p = 0.02), hospital admissions (-5 admissions/100, 95% CI -9 to -2; p = 0.005) and health care costs not related to primary care or outpatient medications (-$922/person, 95% CI -$1577 to -$268; p = 0.008) declined significantly after entry into the SOS program (n = 82), with no significant change in rates of infections (-1.6 infections/100, 95% CI -4.0 to 0.8; p = 0.2). In the year after cohort entry, the rate of ED visits (rate ratio [RR] 0.69, 95% CI 0.53 to 0.90), hospital admissions (RR 0.46, 95% CI 0.29 to 0.74), admissions for incident infections (RR 0.51, 95% CI 0.27 to 0.96) and total health care costs not related to primary care or outpatient medications ($15 635 v. $7310/person-year; p = 0.002) declined significantly among SOS clients compared with the year before. We observed no significant change in any of the primary outcomes among unexposed individuals (n = 303). INTERPRETATION: Although additional research is needed, this preliminary evidence indicates that SOS programs can play an important role in the expansion of treatment and harm-reduction options available to assist people who use drugs and who are at high risk of drug poisoning.

Importance: During the COVID-19 pandemic, modified guidance for opioid agonist therapy (OAT) allowed prescribers to increase the number of take-home doses to promote treatment retention. Whether this was associated with an increased risk of overdose is unclear. Objective: To evaluate whether increased take-home doses of OAT early in the COVID-19 pandemic was associated with treatment retention and opioid-related harm. Design, Setting, and Participants: A retrospective propensity-weighted cohort study of 21â¯297 people actively receiving OAT on March 21, 2020, in Ontario, Canada. Changes in OAT take-home dose frequency were assessed between March 22, 2020, and April 21, 2020, and individuals were observed for up to 180 days to assess outcomes (last date of follow-up, October 18, 2020). Exposures: Exposure was defined as extended take-home doses in the first month of the pandemic within each of 4 cohorts based on OAT type and baseline take-home dose frequency (daily dispensed methadone, 5-6 take-home doses of methadone, daily dispensed buprenorphine/naloxone, and 5-6 take-home doses of buprenorphine/naloxone). Main Outcomes and Measures: Primary outcomes were opioid overdose, interruption in OAT, and OAT discontinuation. Results: Among 16â¯862 methadone and 4435 buprenorphine/naloxone recipients, the median age ranged between 38 and 42 years, and 29.1% to 38.2% were women. Among individuals receiving daily dispensed methadone (n = 5852), initiation of take-home doses was significantly associated with lower risks of opioid overdose (6.9% vs 9.5%/person-year; weighted hazard ratio [HR], 0.73 [95% CI, 0.56-0.96]), treatment discontinuation (51.0% vs 63.6%/person-year; weighted HR, 0.80 [95% CI, 0.72-0.90]), and treatment interruption (19.0% vs 23.9%/person-year; weighted HR, 0.80 [95% CI, 0.67-0.95]) compared with no change in take-home doses. Among individuals receiving daily dispensed buprenorphine/naloxone (n = 662), there was no significant difference in any outcomes between exposure groups. Among individuals receiving weekly dispensed OAT (n = 11â¯010 for methadone; n = 3773 for buprenorphine/naloxone), extended take-home methadone doses were significantly associated with lower risks of OAT discontinuation (14.1% vs 19.6%/person-year; weighted HR, 0.72 [95% CI, 0.62-0.84]) and interruption in therapy (5.1% vs 7.4%/person-year; weighted HR, 0.69 [95% CI, 0.53-0.90]), and extended take-home doses of buprenorphine/naloxone were significantly associated with lower risk of interruption in therapy (9.5% vs 12.9%/person-year; weighted HR, 0.74 [95% CI, 0.56-0.99]) compared with no change in take-home doses. Other primary outcomes were not significantly different between groups. Conclusions and Relevance: In Ontario, Canada, during the COVID-19 pandemic, dispensing of increased take-home doses of opioid agonist therapy was significantly associated with lower rates of treatment interruption and discontinuation among some subsets of patients receiving opioid agonist therapy, and there were no statistically significant increases in opioid-related overdoses over 6 months of follow-up. These findings may be susceptible to residual confounding and should be interpreted cautiously.

BACKGROUND: In September 2009, a live attenuated herpes zoster vaccine (ZVL) became available in Canada. Beginning in September 2016, ZVL was made available to all Ontario residents aged 65-70 through a publicly funded immunization program. We assessed the impact of ZVL availability and its subsequent public funding on herpes zoster burden in this population. METHODS: A population-based study of Ontario residents aged 65-70 between January 2005 and September 2018. We used interventional autoregressive integrated moving average models to examine the impact of ZVL market availability and the publicly funded ZVL program on monthly incidence rate of medically attended herpes zoster, defined as an outpatient visit for herpes zoster with a prescription for a herpes zoster antiviral dispensed ≤5 days before or after the visit, or a herpes zoster-related emergency department (ED) visit or hospitalization. In secondary analyses, we examined impacts on any herpes zoster-related ED visits and hospitalizations. RESULTS: We found no association between ZVL market availability and monthly incidence of herpes zoster (Pâ =â .32) or monthly rates of ED visits and hospitalizations (Pâ =â .88). Conversely, the introduction of publicly funded ZVL reduced the monthly rate of medically attended herpes zoster by 19.1% (from 4.8 to 3.8 per 10â 000 population; Pâ <â .01) and herpes zoster-related ED visits and hospitalizations by 38.2% (from 1.7 to 1.0 per 10â 000 population; Pâ <â .05). CONCLUSIONS: The introduction of a publicly funded immunization program for herpes zoster was associated with reduced disease burden and related acute healthcare service use.

Planning families is an important issue within the HIV community. The primary objective of this study was to explore the fertility desires and intentions of men living with HIV (MLWH). A cross-sectional survey containing 77 questions in 10 domains was developed, validated and administered to MLWH. The sample was stratified by sexual orientation, ethnicity, and city of residence. Logistic regression analyses were conducted to determine sociodemographic correlates of intention to have children. 276 men were recruited, of whom 118 (43%) identified as heterosexual and 158 (57%) as gay, bisexual, two-spirit or queer (GBTQ). 133 (45%) men wished and 120 (44%) actually intended to become a parent. Significantly more heterosexual men desired fatherhood (63% vs 37%, p < .0001) and intended to have children in the future (57% vs. 34%, p < .0001). Among all men, significant predictors of intention to have children were age ≤40, heterosexual orientation, African/Caribbean/Black ethnicity, living in Toronto, higher household income, and being partnered with an HIV-negative individual. When stratified by sexual orientation, younger age remained a significant correlate for both groups. A significant proportion of heterosexual and GBTQ MLWH desire and intend to become a parent. Health care providers and policy makers must support these individuals in their reproductive parenting needs.

Antiretroviral medications are expensive, and people living with HIV often experience challenges accessing and paying for medication due to various obstacles. We used concept mapping to explore the challenges people living with HIV in Ontario, Canada, face when accessing medication. In brainstorming, 68 participants generated 447 statements in response to the focus prompt "Some people living with HIV have trouble getting and paying for prescription drugs because ". These were consolidated into 77 statements, which were sorted (n = 30) and rated (n = 32) on importance and commonality. A ten-cluster concept map consisting of individual- and health system-related clusters was generated. Clusters included: (1) Stigma, (2) Medication-Related Issues, (3) Individual Challenges, (4) Basic Needs, (5) Immigration, (6) Coverage, (7) Trillium Drug Program, (8) Access to Services, (9) System-Level Issues and (10) Access to Professional Services. Statements in Coverage and Basic Needs were rated most important and common although there was variability by Ontario residence and drug coverage mechanisms. Strategies to address challenges were generated in Interpretation (n = 25 participants). Given that continuous access to antiretroviral therapy is necessary to fully realize treatment benefits, policies and interventions that address these challenges are needed.

We examined HIV care and treatment in prison and after release for people with HIV in Ontario, Canada, and compared HIV care and treatment with the general population. We used administrative data to identify people with HIV released from provincial prison in 2010 and in the general population. We calculated the proportion of people with HIV who accessed HIV care in prison. We compared HIV care use between people with HIV on prison release and in the general population. We estimated the proportion of people with HIV on antiretroviral therapy in prison as the ratio of the average numbers of people prescribed antiretroviral therapy in prison in 2009/2010 and people with HIV in prison in January 2010. We compared the proportion of people with HIV on public drug benefits that filled an antiretroviral therapy prescription within 6 months for people postrelease and in the general population. Of 344 people with HIV on prison admission, 34.0% received HIV care in prison. Over 1 year, 63.6% of 330 people with HIV on prison release and 67.7% of 15,819 people with HIV in the general population accessed HIV care (p = 0.118), and 43.3% of people with HIV on prison release and 55.2% of people with HIV in the general population had 2 or more HIV care visits (p < 0.001). In prison, 52.4% of people with HIV (39.5/75.4) were on antiretroviral therapy. Of those accessing drug benefits, 60.1% of 226 people with HIV on prison release and 79.6% of 7458 people with HIV in the general population claimed an antiretroviral therapy prescription within 6 months (p < 0.001). Access to HIV care and treatment were suboptimal in prison, and sustained HIV care and treatment were worse for people post-release compared to the general population. Interventions are needed to support HIV care for this population.

Limited evidence suggests that at the time of release from prison, people with HIV face barriers to health care, which may contribute to worsening HIV clinical outcomes. We aimed to describe health care utilization for people with HIV released from provincial prison in Ontario in 2010, and to compare rates of use with prisoner and general population controls. We used Ontario's administrative health records and data from the Ontario Ministry of Community Safety and Correctional Services on all persons released from provincial prison in 2010. We matched each person with HIV released from provincial prison by age and sex with three controls in each of three groups: people with no HIV released from provincial prison, people with HIV in the general population, and people with no HIV in the general population. We compared rates of use of primary care, non-primary ambulatory care, emergency departments, and hospitalization in the year after the first release from provincial prison in 2010 and in the corresponding period for matched controls. We identified 330 persons with HIV released from provincial prison in 2010. Their median time to first HIV-ambulatory care visit after prison release was 177 days (SD 136-239). Compared to all control groups, people with HIV released from provincial prison had higher rates of primary care use, unscheduled emergency department visits and hospital admissions at 30, 90 and 365 days after release. People with HIV released from provincial prison have a long time to first contact with HIV ambulatory care, and higher rates of health care utilization across health care settings. Interventions are required to facilitate post-release linkage to care for this population.

Women with HIV have higher rates of psychiatric disorders than HIV-negative women, yet little is known about their postpartum mental health and associated service use. The purpose of this study was to characterize HIV-positive women's use of ambulatory and acute mental health services in the first year postpartum, relative to HIV-negative women. Using health administrative data, we identified 861,365 women who had a live birth delivery from April 1, 2002 to March 31, 2012 in Ontario, Canada, of whom 530 were identified to be HIV-positive. We described their use of mental health services, including outpatient mental health visits, psychiatric emergency department (ED) visits and hospitalizations using adjusted odds ratios (aORs) and 95% confidence intervals (CIs). HIV-positive women were more likely to access outpatient mental health services (31.5% vs. 21.0%, aOR, 1.26; 95% CI, 1.03-1.55), but more likely to remain engaged in psychiatrist services only (15.6% vs. 6.5%, aOR, 2.35; 95% CI, 1.41-3.72). They were also more likely to require a psychiatric ED visit or hospitalization (3.3% vs. 1.1%, aOR, 2.74; 95% CI, 1.72-4.12). Our findings highlight the importance of considering postpartum mental health as part of comprehensive reproductive health care for women with HIV.

BACKGROUND: Accessing HIV-related care is challenging for formerly incarcerated people with HIV. Interventions informed by the perspectives of these individuals could facilitate engagement with care and address competing priorities that may act as barriers to this process. METHODS: We used concept mapping to identify and prioritize the main obstacles to engaging with HIV-related care following prison release. In brainstorming sessions, formerly incarcerated people with HIV generated responses to a focused prompt regarding the main barriers to reengaging with care. These were consolidated in 35 statements. Next, participants sorted the consolidated list of responses into groups and rated each from lowest to highest in terms of its importance and feasibility of being addressed. We used cluster analysis to generate concept maps that were interpreted with participants. RESULTS: Overall, 39 participants participated in brainstorming sessions, among whom 18 returned for rating and sorting. Following analysis, a seven-cluster map was generated, with participants rating the 'Practical Considerations' (e.g. lack of transportation from prison) and 'Survival Needs' (e.g. securing housing and food) clusters as most important. Although ratings were generally similar between women and men, women assigned greater importance to barriers related to reconnecting with children. CONCLUSIONS: Using concept mapping, we worked with formerly incarcerated people with HIV to identify and prioritize key challenges related to accessing health and social services following prison release. Transitional intervention programs should include programs and processes that address meeting basic subsistence needs and overcoming logistical barriers related to community re-entry.

Cervical cancer caused by oncogenic types of the human papillomavirus (HPV) is of concern among HIV-positive women due to impairment of immune responses required to control HPV infection. Our objectives were to describe patterns of cervical cancer screening using Pap cytology testing among HIV-positive women in Ontario, Canada from 2008 to 2013 and to identify factors associated with adequate screening. We conducted a retrospective, population-based cohort study among screen-eligible HIV-positive women using provincial administrative health data. We estimated annual proportions tested and reported these with 95% confidence intervals (CI). Next, using person-years as the unit of analysis, we identified factors associated with annual Pap testing using log-binomial regression. A total of 2271 women were followed over 10,697 person-years. In 2008, 34.0% (95%CI 31.1-37.0%) had a Pap test. By 2013, the proportion of HIV-positive women tested was 25.9% (95%CI 23.6-28.2%). Women who were most likely to undergo testing were younger, were immigrants from countries with generalized HIV epidemics, lived in the highest income neighbourhoods, had a female primary care physician, had two or more encounters per year with an infectious disease or internal medicine specialist, and had greater comorbidity. Nearly three in four HIV-positive women were under-screened despite all having universal insurance for medically-necessary services. Annual Pap testing decreased following the 2011-2013 release of new guidelines for a lengthened screen interval for average risk women and a billing disincentive. Clinic-based intervention such as physician alerts or reminders may be needed to improve screening coverage among HIV-positive women.

Timely presentation to care for people newly diagnosed with HIV is critical to optimize health outcomes and reduce onward HIV transmission. Studies describing presentation to care following diagnosis during a hospital admission are lacking. We sought to assess the timeliness of presentation to care and to identify factors associated with delayed presentation. We conducted a population-level study using health administrative databases. Participants were all individuals older than 16 and newly diagnosed with HIV during hospital admission in Ontario, Canada, between April 1, 2007 and March 31, 2015. We used modified Poisson regression models to derive relative risk ratios for the association between sociodemographic and clinical variables and the presentation to out-patient HIV care by 90 days following hospital discharge. Among 372 patients who received a primary HIV diagnosis in hospital, 83.6% presented to care by 90 days. Following multivariable analysis, we did not find associations between patient sociodemographic or clinical characteristics and presentation to care by 90 days. In a secondary analysis of 483 patients diagnosed during hospitalization but for whom HIV was not recorded as the principal reason for admission, 73.1% presented to care by 90 days. Following multivariable adjustment, we found immigrants from countries with generalized HIV epidemics (RR 1.265, 95% CI 1.133-1.413) were more likely to present to care, whereas timely presentation was less likely for people with a mental health diagnosis (RR 0.817, 95% CI 0.742-0.898) and women (RR 0.748, 95% CI 0.559-1.001). Future work should evaluate mechanisms to facilitate presentation to care among these populations.
