Non-pharmacological interventions for smoking in persons with schizophrenia spectrum disorders - A systematic review. Asian J Psychiatr 2021; 56:102530. [PMID: 33465747 DOI: 10.1016/j.ajp.2020.102530] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/01/2020] [Revised: 11/20/2020] [Accepted: 12/16/2020] [Indexed: 01/16/2023]
Abstract
INTRODUCTION The rates and intensity of tobacco use are higher in persons with schizophrenia spectrum disorders (PwS) compared to the general population, contributing to increased morbidity and mortality. We aimed to systematically review randomised control trials (RCTs) that used non-pharmacological interventions to reduce or cease tobacco use in PwS. METHODS We searched PubMed, EBSCO, ProQuest and PsycINFO for RCTs, published between January 2004 and December 2019, which included adult PwS. Studies providing self-reported or biochemically measured reduction of tobacco use and cessation after a minimum follow-up period of 6 months were included. We used the Cochrane Risk of Bias (ROB) tool for assessing the quality of selected studies. RESULTS Of the six included trials, two compared non-pharmacological interventions alone while four compared combinations with pharmacological interventions with routine care. The non-pharmacological interventions varied widely. Continuous abstinence and seven days point-prevalence abstinence (7 PPA) were reported in 2 and 4 studies respectively, with one study assessing both. All six trials measured reduction in the number of cigarettes smoked, but only two trials reported significant reductions in intervention groups. No worsening of psychiatric symptoms was reported. CONCLUSIONS Two trials were rated as "low risk", and 4 trials as "some concerns" on the ROB tool. Heterogeneity among trials precluded meta-analysis. Abstinence was significantly higher among groups who were given combination interventions, and intervention groups in studies showed significantly greater or a trend towards reduction in the number of cigarettes smoked than controls. No specific method of non-pharmacological management was conclusively favoured. IMPLICATIONS Reduction in cigarettes smoked seemed to significantly favour or show non-significant trends favouring intervention groups over controls, while abstinence was significantly higher among groups in studies that used specific combination interventions. Combinations of pharmacological and non-pharmacological treatment were better than non-pharmacological interventions used in isolation, for facilitating abstinence and reduction in cigarettes smoked. Specific interventions such as home visits and contingent reinforcement merit further study. Trials included in this study were conducted in high-income and upper-middle-income countries. Thus, the application of these interventions to low and middle-income countries (LAMICs) needs to be further studied.

It is feasible and effective to help patients with severe mental disorders to quit smoking: An ecological pragmatic clinical trial with transdermal nicotine patches and varenicline. Schizophr Res 2016; 176:272-280. [PMID: 27237598 DOI: 10.1016/j.schres.2016.05.011] [Citation(s) in RCA: 19] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/12/2016] [Revised: 05/06/2016] [Accepted: 05/17/2016] [Indexed: 01/22/2023]
Abstract
Despite the proven association between smoking and high rates of medical morbidity and reduced life expectancy in people with severe mental disorders (SMD), their smoking rates do not decline as they do in the general population. We carried out a non-randomized, open-label, prospective, 9-month follow-up multicentre trial to investigate the clinical efficacy, safety and tolerability of a 12-week smoking cessation programme for patients with SMD in the community under real-world clinical conditions. Eighty-two adult outpatients with schizophrenic/bipolar disorder smoking ≥15 cigarettes/day were assigned by shared decision between doctors and patients to transdermal nicotine patches (TNP) [36(46.2%)] or varenicline [39(50%)]. Short-term efficacy: The 12-week 7-day smoking cessation (self-reported cigarettes/day=0 and breath carbon monoxide levels≤9ppm) prevalence was 49.3%, without statistically significant differences between medications (TNP 50.0% vs varenicline 48.6%, chi-square=0.015, p=1.000). Long-term efficacy: At weeks 24 and 36, 41.3 and 37.3% of patients were abstinent, with no statistically significant differences between treatments. Safety and Tolerability: no patients made suicide attempts/required hospitalization. There was no worsening on the psychometric scales. Patients significantly increased weight [TNP 1.1(2.8) vs varenicline 2.5(3.3), p=0.063], without significant changes in vital signs/laboratory results, except significant decreases in alkaline phosphatase and low-density lipoprotein-cholesterol levels in the varenicline group. Patients under varenicline more frequently presented nausea/vomiting (p<0.0005), patients under TNP experienced skin reactions more frequently (p=0.002). Three patients under varenicline had elevated liver enzymes. In conclusion, we have demonstrated that in real-world clinical settings it is feasible and safe to help patients with stabilized severe mental disorders to quit smoking.

Kishi T, Iwata N. Varenicline for smoking cessation in people with schizophrenia: systematic review and meta-analysis. Eur Arch Psychiatry Clin Neurosci 2015; 265:259-68. [PMID: 25283510 DOI: 10.1007/s00406-014-0551-3] [Citation(s) in RCA: 31] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/16/2014] [Accepted: 09/30/2014] [Indexed: 12/22/2022]
Abstract
We performed an updated meta-analysis of randomized double-blind placebo-controlled trials (RCTs) on the effects of varenicline adjuvant therapy for smoking cessation in people with schizophrenia, on the basis of a previous meta-analysis (Tsoi in Cochrane Database Syst Rev 2:CD007253, 2013). We searched PubMed, the Cochrane Library databases, and PsycINFO up to August 1, 2014. RCTs comparing varenicline adjuvant therapy with placebo in schizophrenia were included. The risk ratio (RR), number needed to harm (NNH), and standardized mean differences with its 95% confidence interval (CI) were used. Seven studies (total n = 439), including 6 with only schizophrenia (total n = 352), 1 with both schizophrenia (n = 77) and bipolar disorder (n = 10), were included. Varenicline was not superior to placebo in smoking cessation (RR = 0.79, 95% CI 0.58-1.08, p = 0.14, 5 RCTs, n = 322). Varenicline failed to show its superiority to placebo for overall, positive, negative, and depressive symptoms. Moreover, there was no significant difference in the discontinuation rate due to all causes, clinical deterioration, or side effects between varenicline and placebo. Although varenicline caused less abnormal dreams/nightmares than placebo (RR = 0.47, 95% CI 0.22-0.99, p = 0.05, NNH = not significant, 4 RCTs, n = 288), it caused more nausea (RR = 1.79, 95% CI 1.20-2.67, p = 0.004, NNH = 6, p = 0.004, 6 RCTs, n = 417). We detected no significant difference in suicidal ideation and depression between varenicline and placebo. Our results suggest that although varenicline adjuvant therapy is well tolerated, varenicline is not superior to placebo for smoking cessation in people with schizophrenia. Because of the limited sample sizes of the available studies, future studies will require larger samples to ensure that these findings are generalizable.

Abstract
BACKGROUND Many studies have shown that the prevalence of smoking in schizophrenia is higher than in the general population. Biological, psychological and social factors influence smoking in patients with schizophrenia. METHODS The study was carried out in psychiatry outpatient clinics in a tertiary care hospital in Sri Lanka. Every third patient was selected using systematic sampling from patients diagnosed with schizophrenia according to ICD-10 clinical criteria. Smoking behaviours were assessed using self-reports. Severity of illness was assessed using Brief Psychiatric Rating Scale (BPRS). Fagerstrom Test for Nicotine Dependence assessed level of dependence. Readiness to Change Questionnaire assessed motivation to change smoking behaviour. RESULTS The sample consisted of 306 patients with schizophrenia. Mean age was 38.93 years (SD 10.98). There were 148 males (48.4%). Mean duration of illness was 12.63 years (SD 8.38). Current medication was oral atypical antipsychotics 103, clozapine 136, oral typicals 29 and depot typicals 38. Prevalence of tobacco use among males was 30.41% (95% CI 22.91 to 37.90) and among females 1.90% (95% CI -0.25 to 4.05). Prevalence of current smoking among males was 20.27% (95% CI 13.72 to 26.82). None of the females smoked. Prevalence of smokeless tobacco use among males was 10.14 (95% CI 5.22 to 15.05) and among females 1.90 (95% CI -0.03 to 4.05). When patients treated with clozapine were excluded from the analysis, prevalence of tobacco use was 41.6% among males and 3.2% among females and prevalence of smoking was 29.9% among males. Prevalence of tobacco use was lowest in patients treated with clozapine 18.31 (95% CI 9.09 to 27.53) and highest in those treated with depot antipsychotics 47.83 (95% CI 25.74 to 69.91). CONCLUSIONS Prevalence of smoking was less than in many countries. This is influenced by prevalence in the general population and low affordability. Risk of tobacco use was significantly less among patients treated with clozapine.

Abstract
Compared to the general population, smokers with schizophrenia (SCZ) have reduced success in quitting smoking with usual approaches. This study tested two manualized behavioral counseling approaches-Treatment of Addiction to Nicotine in Schizophrenia (TANS) or Medication Management (MM)-for smokers who were motivated to quit. Individual counseling sessions were provided by mental health clinicians in mental health settings, along with nicotine patch. The two treatments varied in intensity and frequency of sessions. Eighty-seven subjects were randomized and attended at least one treatment session. Twenty-one percent (n = 18) of participants had continuous abstinence at 12 weeks after the target quit date, which was not significantly different between conditions (15.6% TANS vs. 26.2% MM, chi(2) = 1.50, p = .221). Smokers in both groups significantly reduced smoking as measured by cigarettes per day and expired carbon monoxide. Findings support that mental health clinicians can be trained to effectively help smokers with SCZ maintain tobacco abstinence.

Abstract
People with mental health and addictive (MHA) disorders smoke at high rates and require tobacco treatment as a part of their comprehensive psychiatric care. Psychiatric care providers often do not address tobacco use among people with mental illness, possibly owing to the belief that their patients will not be able to quit successfully or that even short-term abstinence will adversely influence psychiatric status. Progress in the development of treatments has been slow in part because smokers with current MHA disorders have been excluded from most smoking cessation trials. There are several smoking cessation treatment options, including psychological and pharmacological interventions, that should be offered to people with an MHA disorder who smoke. Building motivation and readiness to quit smoking is a major challenge, and therefore motivational interventions are essential. We review the treatment options for people with tobacco dependence and MHA disorders, offer recommendations on tobacco assessment and tailored treatment strategies, and provide suggestions for future research. Treatment efficacy could be enhanced through promoting smoking reduction as an initial treatment goal, extending duration of treatment, and delivering it within an integrated care model that also aims to reduce the availability of tobacco in MHA treatment settings and in the community.
