RESUMO

OBJECTIVES: Electroconvulsive therapy (ECT) can be life-saving in situations where patients are at risk of dying from severe manifestations of psychiatric illness. In some of these cases, patients are unwilling/unable to consent to ECT, and involuntary ECT is required. Such use of involuntary ECT varies substantially across European countries for unclear reasons. The aim of this study was to examine clinical and legal differences in this use of involuntary ECT across European countries. METHODS: A questionnaire based on a case vignette (a 55-year-old female inpatient with psychotic depression at imminent risk of dying from metabolic derangement because of refusal to eat and drink) was sent to an ECT practitioner in each of 31 European countries. RESULTS: We received responses from ECT practitioners in 18 countries. In 7 of these countries, involuntary ECT could be carried out without approval from others and/or involvement of the court system in the case described in the vignette. Practitioners in the remaining 11 countries responded that they either could not carry out involuntary ECT or would have to meet certain requirements before initiating involuntary ECT (e.g., approval from medical/ethics committee and second opinion from an independent psychiatrist). Notably, the rules regarding involuntary ECT differed for adults and minors (more restrictive for the latter) in 6 of the 18 countries. CONCLUSIONS: In many European countries, legislation precludes or delays the use of involuntary ECT. Harmonization of the legislation on involuntary ECT across European countries to allow for better access to this potentially life-saving treatment seems warranted.

RESUMO

BACKGROUND: Postpartum psychotic- or mood disorders are psychiatric emergencies associated with risk of suicide and infanticide. Except from case reports, there are only few descriptions of its treatment. Therefore, we aimed to describe the treatment of women admitted with postpartum psychotic- or mood disorder in Denmark with emphasis on the use of electroconvulsive therapy (ECT). METHODS: We conducted a register-based cohort study of all women with incident postpartum psychotic- or mood disorder (no prior diagnoses of psychotic- or mood disorder or treatment with ECT) requiring admission in the period from 2011 to 2018. For these patients, we described the treatment and the 6-month readmission risk. RESULTS: We identified 91 women with postpartum psychotic- or mood disorder with a median admission length of 27 days (interquartile range: 10-45). Of those, 19% received ECT with a median time from admission to first ECT of 10 days (interquartile range: 5-16). The median number of ECT sessions was eight (interquartile range: 7-12). In the 6 months following discharge, 90% of the women received some form of psychopharmacological treatment (62% antipsychotics, 56% antidepressants, 36% anxiolytics/sedatives, 19% lithium, and 9% mood stabilizing antiepileptics), and 31% were readmitted. CONCLUSION: Psychiatric admission for incident postpartum psychotic- or mood disorder is rare in Denmark. Among those admitted, ECT and psychopharmacological treatment is commonly used. The 6-month readmission risk is high, warranting close follow-up. The fact that there is no international consensus on the optimal treatment of postpartum psychotic- or mood disorder is problematic and calls for action.

RESUMO

OBJECTIVE: Electroconvulsive therapy (ECT) en bloc is defined as ECT administered on 2-3 consecutive days. In Denmark, ECT en bloc is recommended for severe conditions such as catatonia, treatment-resistant mania/psychosis, or imminent risk of suicide. To our knowledge, there are no recent reports on the use of ECT en bloc in clinical practice. Here, we provide such a report. METHODS: We characterized the use of ECT en bloc in the period from 2006-2019 based on data from Danish national registers. Furthermore, we compared mortality rates between patients receiving ECT en bloc and patients receiving standard regimen ECT (not en bloc). RESULTS: We identified 2173 patients who received a total of 2734 ECT en bloc treatment courses in Denmark in the period from 2006 to 2019 (6% of the total number of ECT treatment courses). The use of ECT en bloc was stable over the study period (range: 138-196 patients per year). The most common treatment indications were unipolar depression (41%), psychotic disorder (23%), and bipolar disorder (20%). The vast majority (90%) received ECT en bloc voluntarily. The 1-year mortality rate ratio for ECT en bloc compared to standard regimen ECT was 1.42 (95%CI: 1.03-1.95). CONCLUSION: The use of ECT en bloc in Denmark is stable both in terms of the number of patients treated and treatment indications. In keeping with ECT en bloc being used for severe conditions, those receiving this treatment have a higher mortality rate compared to those receiving standard ECT, warranting careful monitoring during follow-up.

RESUMO

OBJECTIVE: Natural language processing (NLP) methods hold promise for improving clinical prediction by utilising information otherwise hidden in the clinical notes of electronic health records. However, clinical practice - as well as the systems and databases in which clinical notes are recorded and stored - change over time. As a consequence, the content of clinical notes may also change over time, which could degrade the performance of prediction models. Despite its importance, the stability of clinical notes over time has rarely been tested. METHODS: The lexical stability of clinical notes from the Psychiatric Services of the Central Denmark Region in the period from January 1, 2011, to November 22, 2021 (a total of 14,811,551 clinical notes describing 129,570 patients) was assessed by quantifying sentence length, readability, syntactic complexity and clinical content. Changepoint detection models were used to estimate potential changes in these metrics. RESULTS: We find lexical stability of the clinical notes over time, with minor deviations during the COVID-19 pandemic. Out of 2988 data points, 17 possible changepoints (corresponding to 0.6%) were detected. The majority of these were related to the discontinuation of a specific note type. CONCLUSION: We find lexical and syntactic stability of clinical notes from psychiatric services over time, which bodes well for the use of NLP for predictive modelling in clinical psychiatry.

RESUMO

PURPOSE/BACKGROUND: Data on the effect of treatment with antidepressant drugs on metabolic control in diabetes are sparse. In this controlled within-subject before-after study, the impact of initiation and discontinuation of antidepressant treatment on hemoglobin A1c (HbA1c) and low-density lipoprotein (LDL) levels in type 2 diabetes was estimated. METHODS/PROCEDURES: All individuals with newly developed type 2 diabetes (first HbA1c ≥ 6.5%) between 2000 and 2016 in Northern and Central Denmark were identified using register-based health care data. Among these, we identified individuals initiating and discontinuing antidepressant treatment. Using a within-subject before-after design, we examined HbA1c and LDL in the 16 months leading up to and the 16 months after antidepressant treatment initiation or discontinuation, respectively. For comparison, we ran similar time trend analyses in a reference population of age- and sex-matched type 2 diabetes individuals not receiving antidepressant treatment. FINDINGS/RESULTS: Mean HbA1c decreased after initiation of antidepressant treatment (-0.16%; 95% confidence interval [CI], -0.18 to -0.13%). In the reference population, no material change in HbA1c over time (-0.03%; 95% CI, -0.04 to -0.01%) was seen. Mean LDL decreased not only in antidepressant initiators (-0.17 mmol/L; 95% CI, -0.19 to -0.15 mmol/L) but also in the reference population (-0.15 mmol/L; 95% CI, -0.16 to -0.13 mmol/L). Among antidepressant discontinuers, there was also a decrease in HbA1c (-0.32%; 95% CI, -0.37 to -0.28%), with no change in the reference population (-0.02%; 95% CI, -0.04 to 0.00%). Decreases in LDL were found both in antidepressant discontinuers (-0.09 mmol/L; 95% CI, -0.14 to -0.04 mmol/L) and in the reference population (-0.16 mmol/L0; 95% CI, -0.18 to -0.13 mmol/L). IMPLICATIONS/CONCLUSIONS: Antidepressant treatment in type 2 diabetes may have a beneficial effect on glycemic control, as the decrease in HbA1c after discontinuation of antidepressants likely reflects remission of depression. Conversely, antidepressant treatment does not seem to affect LDL levels.

RESUMO

OBJECTIVE: The use of electroconvulsive therapy (ECT) in the treatment of bipolar disorder (BD) remains poorly described. Based on data from Danish registries with complete nationwide coverage, this study of patients with incident BD aimed to describe when, how, and for whom ECT is used in the context of BD. METHODS: We identified patients receiving their first diagnosis of BD in the period from 2008 to 2018, who subsequently received ECT. Descriptive statistics were used to clarify when, how, and for whom ECT is used. RESULTS: We identified 1338 patients with incident BD who subsequently received ECT. The median age at the first ECT session was 50.6 years (interquartile range [IQR]: 26.4), and 62% of those treated with ECT were female. The median time from the diagnosis of BD to the first ECT treatment was 0.6 years (IQR: 2.6), and 58% of the patients receiving ECT had the first treatment within the first year after being diagnosed with BD. The most common indication for the first ECT treatment was depression (mainly non-psychotic depression), followed by mania (mainly psychotic mania). The first ECT session was typically provided to inpatients (97%), upon patient consent (98%) and with bilateral electrode placement (60%). CONCLUSIONS: A substantial proportion of the patients with incident BD who receive ECT require this treatment within the first year after the diagnosis. The most common indication for ECT is depression followed by (psychotic) mania. Inpatient voluntary ECT using bilateral electrode placement is the most common form of administration.

RESUMO

OBJECTIVES: Individuals with bipolar disorder are prone to risk-taking behavior that is subsequently regretted. Here, we investigated whether this also occurs in relation to the use of social media and online dating. METHODS: A questionnaire-based survey focusing on the use of social media and online dating was conducted among individuals attending an outpatient clinic for bipolar disorder, and among individuals attending two general practices in the same region (controls). The association between bipolar disorder and self-reported regretted behavior on social media/online dating sites was investigated using logistic regression with adjustment for age and sex. RESULTS: A total of 124 individuals with bipolar disorder and 196 individuals without affective disorder from the general practices (controls) formed the study sample. Among the individuals with bipolar disorder who used social media, 66% reported regretted behavior as a consequence of this use, whereas only 31% of the controls reported such behavior. The corresponding numbers for individuals who used online dating were 65% for those with bipolar disorder and 31% for the controls. Following adjustment for age and sex, bipolar disorder was associated with elevated risk of regretted behavior in relation to the use of both social media (adjusted odds ratio: 3.6, 95% CI: 2.2, 5.9) and online dating (adjusted odds ratio: 4.1, 95% CI: 2.1, 8.0). CONCLUSIONS: These findings suggest that risk-taking behavior and subsequent regret among individuals with bipolar disorder extend to social media and online dating. Cautious use of these platforms may be particularly relevant for individuals with bipolar disorder.

RESUMO

BACKGROUND: A diagnosis of attention-deficit/hyperactivity disorder (ADHD) requires the presence of impairment alongside symptoms above a specific frequency and severity threshold. However, the question of whether that symptom threshold represents anything more than an arbitrary cutoff on a continuum of impairment requires further empirical study. Therefore, we present the first study investigating if the relationship between ADHD symptom severity and functional impairment is nonlinear in a way that suggests a discrete, nonarbitrary symptom level threshold associated with a marked step increase in impairment. METHODS: Parent reports on the ADHD-Rating Scale (ADHD-RS-IV), the Weiss Functional Impairment Rating Scale (WFIRS-P), and the Strengths and Difficulties Questionnaire were collected in a general population sample of 1st, 2nd, and 3rd graders (N = 1,914-2,044). RESULTS: Piecewise linear regression analyses and nonlinear regression modeling both demonstrated that the relationship between symptom severity (ADHD-RS-IV total score) and impairment (WFIRS-P mean score) was characterized by a gradual linear increase in impairment with higher symptom severity and no apparent step increase or changing rate of increase in impairment at a certain high ADHD-RS-IV total score level. Controlling for socioeconomic status, sex, and co-occurring conduct and emotional symptoms did not alter these results, though comorbid symptoms had a significant effect on impairment. CONCLUSIONS: There was no clear evidence for a discrete, nonarbitrary symptom severity threshold with regard to impairment. The results highlight the continued need to consider both symptoms and impairment in the diagnosis of ADHD.

RESUMO

To reconcile the strong secular persistence of attention-deficit/hyperactivity disorder (ADHD) despite its impairing effects, ADHD traits have been postulated to offer an evolutionary advantage. It has been proposed that such advantages should in particular be observable under time-critical, novel, and resource-depleted conditions requiring response-readiness and high levels of scanning and exploration/foraging. Our objective was to provide the first behavioral test of this hypothesis. Schoolchildren from the general population with no/few (n = 56), mild (n = 50), moderate (n = 48), and severe (n = 48) ADHD traits, defined according to their ADHD-Rating Scale IV (ADHD-RS-IV) total score, participated in an exploratory foraging and response-readiness laboratory test. Here, children searched for coins hidden in locations of varying obscurity in an unfamiliar room for 1 min. Test-performance (number of coins found) adjusted for age, sex, and estimated IQ was analyzed categorically using multiple linear regression analyses and dimensionally by fitting a regression model including the ADHD-RS-IV score as a continuous measure. There were no differences in the mean number of coins between the No/Few (Mean = 7.82), Mild (Mean = 7.76), Moderate (Mean = 7.58), and Severe (Mean = 7.88) groups [F(3,195) = 0.24, p = 0.871]. Furthermore, excluding children with functional impairment, adjusting for verbal working memory and response inhibition, and stratifying for sex did not change these findings. Finally, continuous ADHD traits were not found to be related to test-performance [F(3,195) = 0.73, p = 0.536]. While our results do generally not support the evolutionary advantage theory (i.e., ADHD traits neither conferred an advantage nor a disadvantage), this does not disprove that ADHD traits may have offered advantages via other mechanisms.

RESUMO

OBJECTIVE: The beneficial effect of electroconvulsive therapy (ECT) on suicidality has been documented in clinical trials, whereas naturalistic studies on the topic are scarce and restricted to individuals with mood disorders. Here, based on population-based data from Danish registers, we aimed to investigate the course of self-harm and suicide attempts preceding and following ECT across 4 major mental disorders. This was done to examine whether data from the real-world clinical setting are compatible with the positive results from clinical trials. METHODS: We identified all patients diagnosed with unipolar depression (n = 8843), bipolar disorder (n = 2713), psychotic disorder (n = 2692), or personality disorder (n = 2085) who received ECT for the first time in the period from 2008 to 2019, as well as age-, sex-, diagnosis-, illness duration-, and admission-matched comparison groups not receiving ECT. A mirror-image model was used to examine whether the number of incidents of self-harm/suicide attempts changed following ECT (paired t test). RESULTS: There were substantial and statistically significant reductions in the number of incidents of self-harm/suicide attempts when comparing the month leading up to and the month following initiation of ECT for all diagnostic groups (unipolar depression: reduction, 83% [P < 0.001]; bipolar disorder: reduction, 72% [P < 0.001]; psychotic disorder: reduction, 82% [P < 0.001]; personality disorder: reduction, 83% [P < 0.001]). The analog results for the comparison groups not receiving ECT suggested that these reductions in self-harm/suicide attempts were partly mediated by a protective effect of admission. CONCLUSIONS: Data from the real-world clinical setting are compatible with results from clinical trials with regard to the protective effect of ECT on suicidality.

RESUMO

The COVID-19 pandemic is believed to have a major negative impact on global mental health due to the viral disease itself as well as the associated lockdowns, social distancing, isolation, fear, and increased uncertainty. Individuals with preexisting mental illness are likely to be particularly vulnerable to these conditions and may develop outright 'COVID-19-related psychopathology'. Here, we trained a machine learning model on structured and natural text data from electronic health records to identify COVID-19 pandemic-related psychopathology among patients receiving care in the Psychiatric Services of the Central Denmark Region. Subsequently, applying this model, we found that pandemic-related psychopathology covaries with the pandemic pressure over time. These findings may aid psychiatric services in their planning during the ongoing and future pandemics. Furthermore, the results are a testament to the potential of applying machine learning to data from electronic health records.

RESUMO

OBJECTIVES: The aim was to describe the pre-diagnostic and post-diagnostic psychopharmacological treatment of bipolar disorder over the past two decades. METHODS: We identified all 16 288 individuals aged ≥ 18 years, who received their first diagnosis of bipolar disorder at a psychiatric hospital in Denmark between 1997 and 2014. For each calendar year, we calculated the proportion of patients (with index date in the respective calendar years) who were prescribed psychopharmacological treatment in the 2 years preceding and the 2 years following the date of the first diagnosis of bipolar disorder. For patients diagnosed with bipolar disorder from 2007 to 2010 (n = 3949), we described the psychopharmacological treatment from 1995 to 2016, that is, from up to 16 years prior to and up to 10 years after the diagnosis. RESULTS: Concomitant use of ≥ 2 antidepressants in the 2 years preceding the bipolar disorder diagnosis increased over the study period. In the 2 years following the diagnosis, the use of lithium decreased, while use of atypical antipsychotics (particularly quetiapine), valproate, and lamotrigine increased over the study period. During the 10 years following the diagnosis, 53%-90% of the patients received any psychotropic drug while 12%-26% received treatment with an antidepressant without overlapping treatment with a mood-stabilizing drug. CONCLUSION: The increased use of two or more antidepressants suggests more focus on bipolar disorder as a differential diagnosis to treatment-resistant unipolar depression. The decreased use of lithium (consistent with international trends) and the prevalent use of antidepressants without overlapping treatment with a drug with mood-stabilizing properties are concerning.

RESUMO

OBJECTIVE: Involuntary electroconvulsive therapy (ECT) can be a lifesaving intervention for patients suffering from potentially lethal conditions who are unable to give informed consent. However, its use is not widespread, probably partly because of the scarce data on hard outcomes following involuntary ECT. In Denmark, involuntary ECT is only used when patients are at imminent/potential risk of dying if not receiving ECT. Here, we aimed to estimate the 1-year survival rate after the administration of involuntary ECT as a proxy for the effectiveness of this treatment. METHODS: We conducted a register-based cohort study involving (i) all patients receiving involuntary ECT in Denmark between 2008 and 2019, (ii) age- and sex-matched patients receiving voluntary ECT, and (iii) age- and sex-matched individuals from the general population. One-year survival rates were compared via mortality rate ratios. RESULTS: We identified 618 patients receiving involuntary ECT, 547 patients receiving voluntary ECT, and 3080 population-based controls. The survival rate in the year after involuntary ECT was 90%. For patients receiving involuntary ECT, the 1-year mortality rate ratios were 3.1 (95% confidence interval, 1.9-5.2) and 5.8 (95% confidence interval, 4.0-8.2) compared with those receiving voluntarily ECT and to the population-based controls, respectively. Risk factors for early death among patients receiving involuntary ECT were male sex, being 70 years or older and having organic mental disorder as the treatment indication. CONCLUSIONS: Treatment with involuntary ECT is associated with a high survival rate, suggesting that the intervention is effective. However, patients receiving involuntary ECT constitute a high-risk population that should be monitored closely after this treatment.

RESUMO

PURPOSE: Self-reports of psychosis-related symptoms may be a valuable supplement to clinician-ratings, but more validation studies are required. The aim of this study was to conduct clinical validation for the Symptom Self-rating Scale for Schizophrenia (4S) in an inpatient setting. MATERIALS AND METHODS: Inpatients diagnosed with schizophrenia were invited to participate in the study. The participants completed the 4S, the 5-item World Health Organization Wellbeing Index (WHO-5) and the Sheehan Disability Scale (SDS) at two time points. Trained raters assessed participants using the 6-item Positive And Negative Syndrome Scale (PANSS-6). The relationship between the 4S and PANSS-6, self-reported side effects, functioning and wellbeing was assessed using Spearman's correlation coefficient (rho). RESULTS: Sixty-one participants completed the 4S at least once (yielding a total of 91 completed 4S questionnaires). The 4S total score was weakly correlated with the PANSS-6 total score (rho = 0.37, p < 0.001). The rho's for individual 4S and PANSS-6 subscales and item comparisons ranged from -0.24 (thought disorder) to 0.69 (hallucinations). Finally, the 4S hallucination subscale was also sensitive to change. The 4S was strongly inversely correlated with wellbeing (WHO-5) and moderately inversely correlated with functioning (SDS total score). CONCLUSION: The 4S holds promise as a valid self-report of core schizophrenia symptoms among inpatients. While the hallucination subscale seems superior to existing scales, the thought disorder subscale needs to be re-developed.

RESUMO

To investigate the association between newly developed type 2 diabetes (T2D) and incident psychopharmacological treatment and psychiatric hospital contact. Via Danish registers, we identified all 56 640 individuals from the Central and Northern Denmark Regions with newly developed T2D (defined by the first HbA1c measurement ≥6.5%) in 2000-2016 as well as 315 694 age- and sex-matched controls (without T2D). Those having received psychopharmacological treatment or having had a psychiatric hospital contact in the 5 years prior to the onset of T2D were not included. For this cohort, we first assessed the 2-year incidence of psychopharmacological treatment and psychiatric hospital contact. Secondly, via Cox regression, we compared the incidence of psychopharmacological treatment/psychiatric hospital contact among individuals with T2D to propensity score-matched controls - taking a wide range of potential confounders into account. Finally, via Cox proportional hazards regression, we assessed which baseline (T2D onset) characteristics were associated with subsequent psychopharmacological treatment and psychiatric hospital contact. A total of 8.3% of the individuals with T2D initiated psychopharmacological treatment compared to 4.6% of the age- and sex-matched controls. Individuals with T2D were at increased risk of initiating psychopharmacological treatment compared to the propensity score-matched controls (HR = 1.51, 95% CI = 1.43-1.59), whereas their risk of psychiatric hospital contact was not increased to the same extent (HR = 1.14, 95% CI = 0.98-1.32). Older age, somatic comorbidity, and being divorced/widowed were associated with both psychopharmacological treatment and psychiatric hospital contact following T2D. Individuals with T2D are at elevated risk of requiring psychopharmacological treatment.

RESUMO

BACKGROUND: The quality of life and lifespan are greatly reduced among individuals with mental illness. To improve prognosis, the nascent field of precision psychiatry aims to provide personalised predictions for the course of illness and response to treatment. Unfortunately, the results of precision psychiatry studies are rarely externally validated, almost never implemented in clinical practice, and tend to focus on a few selected outcomes. To overcome these challenges, we have established the PSYchiatric Clinical Outcome Prediction (PSYCOP) cohort, which will form the basis for extensive studies in the upcoming years. METHODS: PSYCOP is a retrospective cohort study that includes all patients with at least one contact with the psychiatric services of the Central Denmark Region in the period from January 1, 2011, to October 28, 2020 (n = 119 291). All data from the electronic health records (EHR) are included, spanning diagnoses, information on treatments, clinical notes, discharge summaries, laboratory tests, etc. Based on these data, machine learning methods will be used to make prediction models for a range of clinical outcomes, such as diagnostic shifts, treatment response, medical comorbidity, and premature mortality, with an explicit focus on clinical feasibility and implementation. DISCUSSIONS: We expect that studies based on the PSYCOP cohort will advance the field of precision psychiatry through the use of state-of-the-art machine learning methods on a large and representative data set. Implementation of prediction models in clinical psychiatry will likely improve treatment and, hopefully, increase the quality of life and lifespan of those with mental illness.

OBJECTIVES: To investigate how individuals with a history of affective disorder use and perceive their use of social media and online dating. METHODS: A questionnaire focusing on affective disorders and the use of social media and online dating was handed out to outpatients from unipolar depression and bipolar disorder clinics and general practice patients with or without a history of affective disorders (latter as controls). The association between affective disorders and use of social media and online dating was analysed using linear/logistic regression. RESULTS: A total of 194 individuals with a history of unipolar depression, 124 individuals with a history of bipolar disorder and 196 controls were included in the analysis. Having a history of unipolar depression or bipolar disorder was not associated with the time spent on social media compared with controls. Using the controls as reference, having a history bipolar disorder was associated with use of online dating (adjusted odds ratio: 2.2 (95% CI: 1.3; 3.7)). The use of social media and online dating had a mood-congruent pattern with decreased and more passive use during depressive episodes, and increased and more active use during hypomanic/manic episodes. Among the respondents with a history of affective disorder, 51% reported that social media use had an aggravating effect on symptoms during mood episodes, while 10% reported a beneficial effect. For online dating, the equivalent proportions were 49% (aggravation) and 20% (benefit), respectively. CONCLUSION: The use of social media and online dating seems related to symptom deterioration among individuals with affective disorder.

RESUMO

OBJECTIVE: To investigate the effectiveness of stimulants in patients with depression, by using naturalistic outcome measures, such as psychiatric admissions, psychiatric bed-days and incidents of intentional self-harm or suicide attempts. METHODS: Via linkage of the Danish nationwide health registers, we identified all patients with a diagnosis of depression initiating stimulants, including methylphenidate, modafinil, amphetamine, dexamphetamine or lisdexamphetamine, from 1995 to 2012. We used a mirror-image model to test whether redemption of a stimulant prescription was associated with a reduction in psychiatric admissions, inpatient days and incidents of intentional self-harm or suicide attempts. Specifically, the number of these outcomes in the 2 years leading up to redemption of a stimulant prescription was compared to the two subsequent years. Similar outcomes were used in a reverse mirror-image model to investigate the effect of stimulant termination. RESULTS: A total of 3354, 935 and 105 patients diagnosed with depression redeemed prescriptions for methylphenidate, modafinil or amphetamine/dexamphetamine/lisdexamphetamine, respectively. Initiation of methylphenidate was not associated with a significant change in psychiatric admissions (mean: -0.02 admissions, p = 0.11) or inpatient days (mean: 0.13 days, p = 0.74). Similar findings were made for modafinil and the amphetamines. In addition, no clinically relevant change in psychiatric admissions or inpatient days was found after termination of a stimulant. After initiation of methylphenidate, the incidents of self-harm or suicide attempts were reduced by 54%, from 68 to 31 events (p = 0.004). No significant change in incidents of self-harm or suicide attempts were found for modafinil or the amphetamines. CONCLUSION: This nationwide study, using naturalistic outcomes, does not support the use of stimulants in patients with depression. However, the use of methylphenidate was associated with a 54% reduction in incidents of self-harm or suicide attempts, indicating that methylphenidate may potentially be useful in patients with depression with suicidal- or self-harming behaviour. However, further studies are needed, before any firm conclusions can be made.
