Opioid dependency rehabilitation with the opioid maintenance treatment programme - a qualitative study from the clients' perspective

Experience of Patients With Heroin Addiction Receiving Methadone Maintenance Treatment in Community Settings in Taiwan

BACKGROUND

The World Health Organization has identified methadone maintenance therapy (MMT) as the most effective treatment for reducing patient dependence on heroin. In Taiwan, MMT has been used as a heroin harm reduction strategy since 2006. Although the effectiveness of MMT in reducing heroin addiction has been examined quantitatively in prison samples, little attention has been paid to the experiences and perspectives of patients with heroin addiction receiving MMT. This study was designed to address this gap in scientific knowledge.

PURPOSE

The aim of this study was to investigate the experiences of individuals struggling with heroin addiction who are receiving MMT in the community.

METHODS

A qualitative descriptive research approach and semistructured interviews were used in this study. We interviewed 14 participants who had received MMT in a medical center in central Taiwan. All of the interview data were recorded, transcribed, and analyzed using qualitative content analysis.

RESULTS

Four themes emerged: (a) a chance to change one's life, (b) the helpfulness of MMT, (c) a sense of being restricted and controlled, and (d) need for support.

CONCLUSIONS/IMPLICATIONS FOR PRACTICE

This article fills a gap in current scholarly understanding of patient experiences and their perspectives on the helpfulness of MMT. Understanding patient experiences and perspectives is critical to informing and developing concrete strategies for clinical practice and MMT policy. Clinical professionals should assess patient needs and concerns to determine whether they are met by current treatment programs. Policymakers should design more flexible policies to facilitate easier access by patients to methadone to reduce the risk of relapse.

Patient's and healthcare provider's experiences with Opioid Maintenance Treatment (OMT): a qualitative evidence synthesis

BACKGROUND

Opioid Maintenance Treatment (OMT) is the gold standard for people with opioid dependence. However, drop-out rates are high, and many patients do not reach desired outcomes. Understanding patients' and healthcare providers' experiences with the treatment can provide valuable information to improve the quality of OMT and to increase acceptability and accessibility of services. The aim of this systematic review is to explore and synthesise the experiences of OMT among persons with opioid dependence and health care providers, to inform policy makers and practitioners on how to improve OMT outcomes.

METHODS

We conducted a qualitative evidence synthesis. We systematically searched in electronic databases (CINAHL, Embase, MEDLINE, and nordic databases) and searched for grey literature. As we identified many studies that met our inclusion criteria, we purposively sampled a manageable number of studies to include in this review. Two researchers independently extracted and coded data from the included studies and used the Andersen's healthcare utilization model to organize and develop codes. We assessed the methodological limitations of the studies, and our confidence in the findings using GRADE CERQual.

RESULTS

We retrieved 56 relevant studies and purposively sampled 24 qualitative studies of patients' and healthcare providers' experiences with OMT. Our analyses resulted in six main themes: (1) External stigma prevents engagement and retention in treatment, (2) Being identified as in OMT contributed to an increased experience of stigma (3) Inadequate knowledge and expertise among healthcare providers affected patients' treatment experiences, (4) Quality of communication between personnel and patients impacts patients' engagement with treatment and treatment outcomes, (5) Patients wanted help with many aspects of their lives not just medication, and (6) Balancing positive expectations of OMT with treatment stigma. We found that stigma was an overarching theme across these themes.

CONCLUSION

Our findings suggest that OMT could be more beneficial for patients if treatment programs prioritize efforts to diminish societal and OMT provider stigma and find strategies to better address patient needs. Initiatives should focus on improving treatment knowledge among providers, encouraging the use of client perspectives, considering the context of family members, and establishing a more holistic and flexible treatment environment.

The impact of relaxing restrictions on take-home doses during the COVID-19 pandemic on program effectiveness and client experiences in opioid agonist treatment: a mixed methods systematic review

BACKGROUND

The COVID-19 pandemic led to an unprecedented relaxation of restrictions on take-home doses in opioid agonist treatment (OAT). We conducted a mixed methods systematic review to explore the impact of these changes on program effectiveness and client experiences in OAT.

METHODS

The protocol for this review was registered in PROSPERO (CRD42022352310). From Aug.-Nov. 2022, we searched Medline, Embase, CINAHL, PsycInfo, Web of Science, Cochrane Register of Controlled Trials, and the grey literature. We included studies reporting quantitative measures of retention in treatment, illicit substance use, overdose, client health, quality of life, or treatment satisfaction or using qualitative methods to examine client experiences with take-home doses during the pandemic. We critically appraised studies using the Mixed Methods Appraisal Tool. We synthesized quantitative data using vote-counting by direction of effect and presented the results in harvest plots. Qualitative data were analyzed using thematic synthesis. We used a convergent segregated approach to integrate quantitative and qualitative findings.

RESULTS

Forty studies were included. Most were from North America (23/40) or the United Kingdom (9/40). The quantitative synthesis was limited by potential for confounding, but suggested an association between take-home doses and increased retention in treatment. There was no evidence of an association between take-home doses and illicit substance use or overdose. Qualitative findings indicated that take-home doses reduced clients' exposure to unregulated substances and stigma and minimized work/treatment conflicts. Though some clients reported challenges with managing their medication, the dominant narrative was one of appreciation, reduced anxiety, and a renewed sense of agency and identity. The integrated analysis suggested reduced treatment burden as an explanation for improved retention and revealed variation in individual relationships between take-home doses and illicit substance use. We identified a critical gap in quantitative measures of patient-important outcomes.

CONCLUSION

The relaxation of restrictions on take-home doses was associated with improved client experience and retention in OAT. We found no evidence of an association with illicit substance use or overdose, despite the expansion of take-home doses to previously ineligible groups. Including patient-important outcome measures in policy, program development, and treatment planning is essential to ensuring that decisions around take-home doses accurately reflect their value to clients.

Individualizing methadone treatment with split dosing: An underutilized tool

Methadone's long half-life typically allows for once daily dosing. However, a growing body of evidence and clinical experience shows that some patients may benefit from twice-daily ("split") dosing to produce more stable symptoms and minimize side effects, independent of serum peak-to-trough levels. Concerns regarding split dosing typically center on diversion and poor adherence and must be taken seriously. However, policy changes during COVID-19 demonstrate that the rigidity historically applied to methadone may be unnecessarily stringent. Given clinical advances and policy updates, we believe clinicians should weigh the risks and benefits of this underutilized tool for select patients, as we await the evidence-based recommendations our patients deserve.

The Lived Experience of Medication for Opioid Use Disorder: Qualitative Metasynthesis

PURPOSE OF THE STUDY

Buprenorphine and methadone, when used as maintenance therapy in opioid use disorder (OUD), can significantly reduce the risk of death after an opioid overdose. Despite the many benefits, medication for OUD (MOUD) remains controversial and underutilized. The aim of this study was to (a) identify studies that explicate the lived experience of MOUD, (b) conduct a methodologically sound critical quality assessment, (c) conduct a metasynthesis of identified qualitative studies, and (d) analyze the results through the lenses of critical social justice, feminist standpoint, and social theories to inform a more culturally responsive, effective, and holistic approach to treatment to increase the utilization of and receptivity to MOUD in the treatment of OUDs.

DESIGN AND METHODS

Metasynthesis is the deliberate process of synthesizing data from multiple qualitative studies to create a new interpretation of previously published research. Our metasynthesis focused on forming a new interpretation of the lived experience of MOUD. Of the 292 studies identified, eight met inclusion criteria. The overall quality of the studies was variable. The study population included adults aged ≥ 18 years with OUD or dependency.

RESULTS

Metasynthesis produced three overarching themes: (a) The duplexity of MOUD creates ambivalence in how a person experiences MOUD; (b) the structure of treatment and systemic influences matter, and (c) MOUD as a stepping-stone with multiple meanings in recovery.

IMPLICATIONS

Understanding experiential dualities allows professionals to see from other perspectives and can inform interventions and treatment structures as well as serve as a backdrop for social change. The synthesized new meaning of MOUD was an ambivalent experience influenced by intersectionality.

Application of the COM-B model to patient barriers and facilitators of retention in medication treatment for opioid use disorder in rural Northeastern United States: A qualitative study

Introduction

Medications for opioid use disorder (MOUD) reduce illicit opioid use and overdose mortality, but effectiveness remains limited by poor treatment retention. Understanding multilevel barriers and facilitators to retention from the patient perspective can guide intervention strategies to improve retention.

Methods

We conducted semi-structured telephone interviews to elicit perspectives of individuals with opioid use disorder (OUD) currently (n = 19) and formerly (n = 16) receiving treatment from a multi-clinic outpatient MOUD program in Pennsylvania in July 2020 to January 2021. The Capability, Opportunity, Motivation, Behavior model provided a theoretical framework for analysis.

Results

Based on interview themes, physical, rather than psychological, capability was more salient to MOUD engagement, and pertained to individual-level factors such as side effects, withdrawal, and the degree to which MOUD addressed participants' need for pain management. Co-existing mental health conditions also challenged participants' physical ability to attend appointments. The opportunity domain contained both physical and social aspects. Physical opportunity for MOUD engagement centered on community-level factors related to MOUD access (e.g., distance, transportation) and clinical-level factors including program policies. Themes related to social opportunity included interpersonal influences-such as therapeutic and social support-and stigma associated with OUD and MOUD. Motivation emerged as the dominant domain for patients. Reflective motivation factors included individual-level factors such as participants' recognition of their addiction and "readiness" to quit illicit opioid use, attitudes toward MOUD, future treatment expectations, motivation to engage in MOUD, and perceived consequences of disengagement. Automatic motivation factors included the degree to which MOUD created a sense of normalcy for participants and the use of illicit drugs to numb emotions.

Conclusions

Factors at the individual, interpersonal, clinical, community, and societal levels influenced patients' capability, opportunity, and motivation to engage in MOUD. Understanding such factors can inform implementation strategies to improve retention.

Patients' experiences of continued treatment with extended-release naltrexone: a Norwegian qualitative study

Background

The opioid antagonist extended-release naltrexone (XR-NTX) in the treatment of opioid use disorder (OUD) is effective in terms of safety, abstinence from opioid use and retention in treatment. However, it is unclear how patients experience and adjust to losing the possibility of achieving an opioid effect. This qualitative study is the first to explore how people with opioid dependence experience XR-NTX treatment, focusing on the process of treatment over time.

Methods

Using a purposive sampling strategy, semi-structured interviews were undertaken with 19 persons with opioid use disorder (15 men, four women, 22–55 years of age) participating in a clinical trial of XR-NTX in Norway. The interviewees had received at least three XR-NTX injections. Qualitative content analysis with an inductive approach was used.

Findings

Participants described that XR-NTX treatment had many advantages. However they still faced multiple challenges, some of which they were not prepared for. Having to find a new foothold and adapt to no longer gaining an effect from opioids due to the antagonist medication was challenging. This was especially true for those struggling emotionally and transitioning into the harmful use of non-opioid substances. Additional support was considered crucial. Even so, the treatment led to an opportunity to participate in society and reclaim identity. Participants had strong goals for the future and described that XR-NTX enabled a more meaningful life. Expectations of a better life could however turn into broken hopes. Although participants were largely optimistic about the future, thinking about the end of treatment could cause apprehension.

Conclusions

XR-NTX treatment offers freedom from opioids and can facilitate the recovery process for people with OUD. However, our findings also highlight several challenges associated with XR-NTX treatment, emphasizing the importance of monitoring emotional difficulties and increase of non-opioid substances during treatment. As opioid abstinence in itself does not necessarily equal recovery, our findings underscore the importance of seeing XR-NTX as part of a comprehensive, individualized treatment approach.

Exploring the experiences of clients receiving opioid use disorder treatment at a methadone clinic in Kenya: a qualitative study

BACKGROUND

Assessing the experiences of individuals on methadone treatment is essential to help evaluate the treatment program's effectiveness. This study aimed to explore the experiences of patients receiving methadone treatment at a clinic in Nairobi, Kenya.

METHOD

This study employed an exploratory qualitative study design. Through purposive sampling, participants were enrolled from individuals attending a methadone clinic for at least 2 years. Semi-structured individual interviews were used to collect data on substance use and experience before methadone treatment and experiences after starting methadone treatment, including benefits and challenges. Interviews were transcribed, and NVIVO 12 software was used to code the data using the preidentified analytical framework. Thematic analyses were utilized to identify cross-cutting themes between these two data sets. Seventeen participants were enrolled.

RESULTS

Seventeen participants were enrolled comprising 70% males, with age range from 23 to 49 years and more than half had secondary education. The interview data analysis identified four themes, namely: (a) the impact of opioid use before starting treatment which included adverse effects on health, legal problems and family dysfunction; (b) learning about methadone treatment whereby the majority were referred from community linkage programs, family and friends; (c) experiences with care at the methadone treatment clinic which included benefits such as improved health, family reintegration and stigma reduction; and (d) barriers to optimal methadone treatment such as financial constraints.

CONCLUSION

The findings of this study show that clients started methadone treatment due to the devastating impact of opioid use disorder on their lives. Methadone treatment allowed them to regain their lives from the adverse effects of opioid use disorder. Additionally, challenges such as financial constraints while accessing treatment were reported. These findings can help inform policies to improve the impact of methadone treatment.

"The idea is to help people achieve greater success and liberty": A qualitative study of expanded methadone take-home access in opioid use disorder treatment

Background: Prior to the COVID-19 pandemic, the United States (US) was already facing an epidemic of opioid overdose deaths. Overdose deaths continued to surge during the pandemic. To limit COVID-19 spread and to avoid disruptions in access to medications for opioid use disorder (MOUD), including buprenorphine and methadone, US federal and state agencies granted unprecedented exemptions to existing MOUD guidelines for Opioid Treatment Programs (OTPs), including loosening criteria for unsupervised take-home doses. We conducted a qualitative study to evaluate the impact of these policy changes on MOUD treatment experiences for providers and patients at an OTP in California. Methods: We interviewed 10 providers (including two physicians, five social worker associates, and three nurse practitioners) and 20 patients receiving MOUD. We transcribed, coded, and analyzed all interviews to identify emergent themes. Results: Patient participants were middle-aged (median age 51 years) and were predominantly men (53%). Providers discussed clinical decision-making processes and experiences providing take-homes. Implementation of expanded take-home policies was cautious. Providers reported making individualized decisions, using patient factors to decide if benefits outweighed risks of overdose and misuse. Decision-making factors included patient drug use, overdose risk, housing status, and vulnerability to COVID-19. New patient groups started receiving take-homes and providers noted few adverse events. Patients who received take-homes reported increased autonomy and treatment flexibility, which in turn increased likelihood of treatment stabilization and engagement. Patients who remained ineligible for take-homes, usually due to ongoing non-prescribed opioid or benzodiazepine use, desired greater transparency and shared decision-making. Conclusion: Federal exemptions in response to COVID-19 led to the unprecedented expansion of access to MOUD take-homes within OTPs. Providers and patients perceived benefits to expanding access to take-homes and experienced few adverse outcomes, suggesting expanded take-home policies should remain post-COVID-19. Future studies should explore whether these findings are generalizable to other OTPs and assess larger samples to quantify patient-level outcomes resulting from expanded take-home policies.

Life satisfaction among individuals with opioid use disorder receiving extended-release naltrexone: A 12-week randomized controlled trial and a 36-week follow-up

INTRODUCTION

Life satisfaction (LS) in opioid-dependent individuals is lower than in the general population. This study aimed to explore changes in LS during short- and long-term treatment with extended-release naltrexone (XR-NTX).

METHODS

This open-label 12-week clinical trial randomized 159 participants to either monthly XR-NTX or daily buprenorphine-naloxone (BP-NLX). In a subsequent 36-week follow-up study on XR-NTX, participants either continued or switched to XR-NTX. The study collected data on the Temporary Satisfaction with Life (TSWL) and illicit opioid use every fourth week. The research team assessed changes in TSWL by a linear mixed model and growth mixture model. The study assessed relationship between opioid use and TSWL by a linear mixed model.

RESULTS

Change in LS differed significantly between the groups in both study periods. TSWL scores were significantly higher in the XR-NTX group at week 4 (p = 0.013) and week 8 (p = 0.002). In the follow-up period, the groups were significantly different only at week 16 (p = 0.031) and week 48 (p = 0.025), with the higher TSWL scores in the XR-NTX continued group. Increase in opioid use by one day was associated with a 0.12 point lower mean TSWL score. Both study periods identified groups with low and high LS levels. In the trial period, the TSWL scores exhibited a significant increase from baseline to week 12 in both groups, p < 0.001 and p = 0.011 in the low and high LS group, respectively. In the follow-up period, the TSWL scores exhibited a significant increase from week 16 to week 48 (p = 0.003) in the high LS group, while the low LS group showed persistently lower values throughout that period.

CONCLUSIONS

XR-NTX treatment given once monthly is associated with higher LS, as measured by TSWL, compared to daily use of BP-NLX. The majority of the participants had relatively low TSWL scores and did not report any change in TSWL during longer-term treatment. The study found a significant association between more frequent illicit opioid use and a low or decreased LS during follow-up.

It is just that people treat you like a human being: The meaning of dignity for patients with substance use disorders

INTRODUCTION

Patients who suffer from substance use disorder (SUD) might receive services from different service providers in an opioid maintenance treatment programme (OMT) and have a widespread and complex need for nursing.

BACKGROUND

Literature reveals that prejudices against people with SUD exist. There is a lack of studies exploring patients with SUD experiences of preserving their dignity in the encounter with healthcare staff. The aim of the study was to gain insight into the meaning of dignity for patients with SUD.

METHODS

The research design was descriptive and interpretative. In the interpretation of qualitative in-depth interviews with six patients, a hermeneutical approach based on Gadamer (Truth and method, Sheed & Ward, London, UK, 1989) was used.

RESULTS

Analysis resulted in three mains themes about the meaning of dignity: (a) The material dimension. (b) To be respected by others. (c) The inner experience. Factors enhancing dignity in the encounters were as follows: (a) Being respected and acknowledged. (b) Being cared for. (c) Knowledge and persistent relation. Factors depriving dignity were as follows: (a) Stigma and prejudice. (b) Insufficient relations and lack of confirmation. (c) Experiencing disrespectful/patronising attitudes and lack of knowledge.

CONCLUSIONS

The material dimension of dignity containing an aesthetically aspect was important for these patients. Dignity was also experienced as strongly connected to respect. Dignity can be enhanced by treating patients with SUD with understanding and respect, and dignity can be inhibited through stigmatization of patients with SUD, as well as by caregivers' lack of knowledge.

RELEVANCE TO CLINICAL PRACTICE

The study clarifies a need for more knowledge about SUD among healthcare staff, as well as promotes ethical awareness in encounters with patients regardless of their background.

Helpful Ingredients in the Treatment of Long-Term Substance Use Disorders: A Collaborative Narrative Study

Relatively few individuals with a substance use disorder (SUD) seek or receive treatment, and knowledge about the effective ingredients in SUD treatment, from the perspective of those who receive it, is scarce. Our study purpose was to explore the experiences of those with long-term SUDs and the aspects they found helpful during treatment and long-term recovery. Semi-structured interviews were conducted with 18 participants, each of whom had been diagnosed with a long-term SUD, and who had been abstinent for at least 5 years. A resource group of peer consultants in long-term recovery from SUDs contributed to study planning, preparation, and initial analyses. Participants preferred individualized, long-term treatment, and support from both therapists and other clients. They further acknowledged the importance of their own sense of responsibility for their treatment and recovery success. Greater focus should be placed on viewing long-term SUD as a long-term condition, similar to somatic diseases, and SUD treatment services should place greater emphasis on developing partnership care models, long-term monitoring and support, and actively engaging recovered clients in the care of others in SUD treatment.

Standards for opioid use disorder care: An assessment of Nordic approaches

Aims:

Outcomes in opioid use disorder (OUD) in Nordic countries have improved with integrated treatment and harm-reduction programmes. Approaches and the standard of care are different across the region. Evidence of treatment needs and current approaches are defined from evidence to inform development of a common standard.

Method:

Evidence of population sizes and treatment approach collected. Common standards for care (harm reduction, pharmacotherapy, psychology/social therapy) defined for each country.

Results:

Evidence defines number in treatment; potential population needing treatment not defined for all countries. Populations sizes, treatment access (ratio in treatment programme compared to total country population) defined: Sweden 4,000 in OUD care (access ratio 40); Finland 3,000 (55); Norway 8,000 (154); Denmark 7,500 (132). Approach to treatment similar: integrated treatment programmes standard. Care provided by specialists in outpatient clinics/primary care; secondary care/inpatient services are available. Harm reduction is limited in Sweden but available and more accessible elsewhere. Treatment entry criteria: access relatively unlimited in Norway and Denmark, more limited in Finland and Sweden. Standards of care defined: easy access to high-quality services, individual planning, care not limited by time, management of relapse, education for patients, continuous engagement, holistic approach including management of comorbidities, needle equipment programmes without limit, treatment in prisons as community.

Conclusion:

There are opportunities to improve OUD care in the Nordics. Policy makers and clinicians can advance OUD care and share common success factors. Collaborative work across the Nordic countries is valuable. Further research in clinical practice development can yield important results for the benefit of patients with OUD.

Barriers to progressing through a methadone maintenance treatment programme: perspectives of the clients in the Mid-West of Ireland's drug and alcohol services

Background

The ‘perfect’ journey through an Irish Methadone Maintenance Treatment Programme (MMTP) would have a client engage appropriately with all relevant services available to them, inclusive of psychiatry, counselling, out-reach support, nursing and psychology. Concurrently, a client would ideally adhere to their prescribed methadone-dosing regimen, until a client is stabilised allowing them to function optimally. At this point, a client should transfer to the GP community setting. Unfortunately, this fails to occur. To date, very few studies have specifically investigated the reasons why a cohort of clients remain ‘trapped’ in the high risk, specialist clinical setting.

Methods

Qualitative detailed semi-structured interviews were undertaken with 17 clients of one of Ireland’s Health Service Executive (HSE) Drug and Alcohol Services, entitled ‘HSE Mid-West Limerick Drug and Alcohol Service’. Each client had a severe Opioid Use Disorder (OUD) and clients had spent on average 7.5 years engaging with the MMTP.

Results

Participants’ life journey prior to an OUD included Adverse Childhood Experiences (ACEs) and early exposure to illicit drug use. Shared life events resulting in their initiating and sustaining an OUD involved continuous hardship into adulthood, mental illness and concurrent benzodiazepine use disorder, often resulting in harrowing accounts of participants’ loneliness and lack of life purpose. Their living environments, an erroneous understanding of their illness and poor communication with allied health professionals further perpetuated their OUD. Positive factors influencing periods of abstinence were familial incentives and a belief in the efficacy of methadone. Clients own suggestions for improving their journeys included employing a multi-sectorial approach to managing OUD and educating themselves and others on opioid agonist treatments. If clients were not progressing appropriately, they themselves suggested enforcing a ‘time-limit’ on clients to engage with the programme or indeed for their treatment to be postponed.

Conclusions

To optimise the functioning of the MMTP, three tasks need to be fulfilled: 1) Reduce the incidences of ACEs, 2) Diagnose and treat clients with a dual diagnosis 3) Educate clients, their families, the public and allied health care professionals on all aspects of OUD. A cross- departmental, inter-governmental approach is needed to address opioid misuse as a societal issue as a whole.

Challenges in implementing opioid agonist therapy in Lebanon: a qualitative study from a user's perspective

Background

Opioid agonist therapy (OAT) has been implemented for the treatment of individuals with opioid use disorders in Lebanon since 2011, but has not been evaluated yet. The aim of the study is to describe the implementation of the first pilot OAT program in Lebanon from the users’ perspective.

Methods

Data collectors gathered data from male participants during June 2016-July 2016. Eighty-one out of 94 patients agreed to participate in the study. Data regarding access to treatment, satisfaction with the treatment protocol and treatment outcomes, patient-provider relationship, and misuse and diversion was collected through semi-structured qualitative interviews. Data saturation was reached after 81 interviews; once no new themes were reported.

Results

Findings showed inequalities in access to treatment and showed that OAT improved mental and social wellbeing among users who had financial access and complied with the program protocols. Registering in the program protected users from arrest and reduced their economic burden. Among the main encountered challenges were fear of dependence to buprenorphine, restricted geographical access to treatment, misuse and diversion of buprenorphine.

Conclusion

Results implicate inequalities in access to OAT as one important gap to be tackled in the management of OAT in Lebanon. Further research should be done in order to understand the challenges in the implementation of the program from the providers’ perspectives.

Opioid overdose leading to intensive care unit admission: Epidemiology and outcomes

PURPOSE

There is a scarcity of studies assessing the patient population admitted to the intensive care unit (ICU) with opioid overdose. We sought to characterize the epidemiologic features and outcomes of this patient population.

MATERIALS AND METHODS

This is a retrospective cohort study of adult patients admitted to the ICU at University of Louisville Hospital for opioid overdose. We reviewed each patient's hospital record for demographic data, comorbidities, opioid used, coingestions, and outcomes.

RESULTS

We included 178 adult patients, of which 107 (60%) were females. The median age was 41 years (interquartile range [IQR], 23). Oxycodone and hydrocodone were the 2 most commonly abused opioids. Benzodiazepines were the most common drug coingested, followed by amphetamines. Tobacco smoking, chronic pain, and alcoholism were the most frequent comorbidities identified. Mental disorders were also common. Most patients required invasive mechanical ventilation (84.8%). Median ICU length of stay was 3 days. Eighteen patients (10.1%) died in the hospital, whereas 6 patients (3.4%) were discharged to a nursing home. Patients who had any coingestion were significantly more likely to undergo invasive mechanical ventilation (91% vs 77%; P=.014) and had longer ICU length of stay (3 [IQR, 2] vs 2 [IQR, 1.8] days; P=.024).

CONCLUSION

Opioid overdose is a common cause of ICU admission and affects a relatively young population. Most have respiratory failure requiring mechanical ventilation. It is associated with a relatively high inhospital mortality. Coingestions appear to have an impact on outcomes.
