RESUMEN

BACKGROUND: Severe mental illness (SMI) imposes a substantial worldwide burden of disability, highlighting the need for comprehensive and adaptable mental health services. This study aims to assess the efficacy and cost-effectiveness of community-based mental health services (CBMHS) in reducing relapse and rehospitalization rates among individuals with SMI in Iran. METHOD: A systematic review and meta-analysis were conducted. Medline, EMBASE, ISI, SCOPUS, and ProQuest were searched until December 2022. We focused on randomized controlled trials, quasi-experimental studies, or economic studies related to individuals with SMI. Out of 127 articles, 17 were selected for a full-text review. The primary outcomes were the severity of psychopathology, rehospitalization rates, and the mental health of caregivers. We also examined community-based interventions and their impact on various outcomes. Data extraction and risk of bias assessment were performed, and critical appraisal was conducted using JBI checklists. Meta-analysis was carried out using STATA software. (PROSPERO registration. CRD42022332660). RESULT: Rehospitalization rates among patients who received CBMHS were significantly lower, with an odds ratio of 2.14 (95% CI: 1.44 to 3.19), indicating a 2.14 times lower likelihood than those who received treatment as usual. A reduction in psychopathology accompanied this, SMD: -0.31, 95% CI: -0.49 to -0.13, I2 = 40.23%). Moreover, there was a notable improvement in social skills (SMD: -0.7, 95% CI: -0.98 to -0.44, I2 = 0.00%). The burden on caregivers also decreased (SMD: -0.55, 95% CI: -0.99 to -0.1, I2 = 63.2). The Incremental Cost-Effectiveness Ratio (ICER) for QUALY was acceptable, albeit with a wide range of 613 to 8400 Dollars. CONCLUSION: CBMHS has demonstrated effectiveness and efficiency in Iran as a developing country. Additionally, it shows promise in mitigating the shortage of acute psychiatry beds. Using multiple data collection tools poses a limitation regarding data consolidation and conducting a meta-analysis.

RESUMEN

BACKGROUND: This systematic review aims to comprehensively assess the diagnostic accuracy of cognitive screening tools validated for older adults in Iran, providing evidence-based recommendations for clinicians and researchers. METHODS: A comprehensive search in March 2023 across Web of Science, PubMed, Scopus, ScienceDirect, SID, IranMedex, and IranDoc, enhanced by hand-searching references and Google Scholar, identified cross-sectional studies on cognitive screening in Iranian seniors. We assessed diagnostic accuracy, cognitive domains, and test strengths and weaknesses. A bivariate random-effects meta-analysis provided summary estimates and 95% confidence intervals, illustrated in forest plots. RESULTS: Our review, derived from an initial screening of 38 articles, focused on 17 studies involving 14 cognitive screening tools and participant counts from 60 to 350, mostly from specialized clinics. The MMSE was the only tool examined in at least three studies, prompting a meta-analysis revealing its sensitivity at 0.89 and specificity at 0.77 for dementia detection, albeit amidst significant heterogeneity (I^2 > 80%). ACE-III demonstrated the highest diagnostic accuracy for MCI and dementia, while MoCA's performance was deemed adequate for MCI and excellent for dementia. High bias risk in studies limits interpretation. CONCLUSION: This review identifies key cognitive tools for dementia and MCI in Iranian older adults, tailored to educational levels for use in primary and specialized care. It emphasizes the need for further validation to enhance diagnostic precision across diverse settings, within a concise framework prioritizing brevity and accuracy for clinical applicability.

RESUMEN

Background: Paying attention to the needs of patients with psychiatric disorders has recently come into focus. Failure to meet the needs of patients can affect their quality of life. This study aimed to determine the main areas of the needs of patients with severe psychiatric disorders and evaluate their relationship with the quality of life. Methods: In this cross-sectional study, 174 patients with severe mental illness who were referred to Iran Psychiatric Hospital for hospitalization or outpatient treatment were enrolled in this study (68 with schizophrenia and schizoaffective disorder, 106 with bipolar disorder type 1). A qualified psychiatry resident conducted interviews with each patient to determine their needs using the Camberwell Assessment of Need Short Appraisal Schedule (CANSAS) and the severity of their illness using the Hamilton Depression Rating Scale (HAM-D), Positive and Negative Syndrome Scale (PANSS), and Young Mania Rating Scale. A checklist for demographic data and the World Health Organization Quality of Life Brief Version (WHOQOL-BREF) questionnaire was completed by patients. Data were analyzed using descriptive statistics. Since the number of needs distribution was not normal, we used the Mann-Whitney, Kruskal-Wallis, and chi-square tests for qualitative variables. Results: The total number of patient needs was 9 (mean = 9.1, SD = 3.7). The most unmet needs were intimate relationships (69.5%), sexual expression (65.5%), and information on condition and treatment (51.1%). Unmet needs showed a negative correlation with the quality of life (P < 0.001) and a positive correlation with the severity of depression (P = 0.045), negative symptoms (P = 0.001), and general psychopathology (P < 0.001). Conclusion: A higher number of unmet needs of severe psychiatric patients is associated with lower quality of life and more severe disorders.

RESUMEN

BACKGROUND: For screening and distinguishing between mild neurocognitive disorder (mNCD) and normal cognitive age-related changes in primary care centers, a simple and practical tool is necessary. Therefore, this study aims to determine the validity and reliability of the Farsi version of the Ascertain Dementia 8-item (AD8-F) informant interview in patients with mNCD. METHODS: This is a study of the psychometric properties of the Farsi AD8. The participants include sixty informant-patient dyads with mNCD and sixty controls with normal cognition. The AD8 was compared to the mini-mental state examination (MMSE) and the Mini-Cog. As a gold standard, the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) criteria for mNCD was used. The reliability was measured using internal consistency and test-retest. Validity was assessed by evaluating the content, concurrent, and construct validity. Data were analyzed via Cronbach's α, Pearson correlation, independent t-test, and analysis of variance (ANOVA) and area under the curve (AUC) by statistical package for the social sciences (SPSS) v.23. RESULTS: Cronbach's α was 0.71. Test-retest reproducibility was 0.8. The AD8 had inverse correlations with the Mini-Cog (r = - 0.70, P < 0.01) and MMSE (r = - 0.56, P < 0.01). The area under the curve was 0.88. The optimal cutoff score was > 2. Sensitivity and specificity were 80 and 83%, respectively. The positive predictive value was 83%. The negative predictive value was 81%. CONCLUSION: Our results suggest that this tool can be used as a screening tool to detect a mild neurocognitive disorder in primary care centers.

RESUMEN

BACKGROUND: Cognitive disorders are one of the important issues in old age. There are many cognitive tests, but some variables affect their results (e.g., age and education). This study aimed to evaluate the reliability and validity of A Quick Test of Cognitive Speed (AQT) in screening for mild cognitive impairment (MCI) and dementia. METHODS: This is a psychometric properties study. 115 older adults participated in the study and were divided into three groups (46 with MCI, 24 with dementia, and 45 control) based on the diagnosis of two geriatric psychiatrists. Participants were assessed by AQT and Mini-Mental State Examination (MMSE). Data were analyzed using Pearson correlation, independent t-test, and ROC curve by SPSS v.23. RESULTS: There was no significant correlation between AQT subscales and age and no significant difference between the AQT subscales in sex, educational levels. The test-retest correlations ranges were 0.84 from 097. Concurrent validity was significant between MMSE and AQT. Its correlation was with Color - 0.78, Form - 0.71, and Color-Form - 0.72. The cut-off point for Color was 43.50 s, Form 52 s, and Color-Form 89 s were based on sensitivity and specificity for differentiating older patients with MCI with controls. The cut-off point for Color was 62.50 s, for Form 111 s, and Color-Form 197.50 s based on sensitivity and specificity measures for differentiating older patients with dementia and MCI. CONCLUSION: The findings showed that AQT is a suitable tool for screening cognitive function in older adults.

RESUMEN

Deregulation of the renin-angiotensin system (RAS) plays an important role in suicide. Angiotensin converting enzyme (ACE) gene is a key component in this system. The relationship between insertion/deletion (I/D) polymorphism of ACE gene with suicide attempt (SA) is controversial. According to previous studies, allele D in this polymorphism has been considered as a potential risk factor for suicide. However, no study has been conducted in Iran to investigate this matter. This case-control study has focused on investigating the association of ACE I/D polymorphism (rs1799752) with SA in an Iranian population. The frequency of genotypes was 14% for II, 55% for ID, and 31% for DD in the case group (100 persons), and 18% for II, 74% for ID, and 8% for DD in control group (100 persons). Results show there was a significant difference in the distribution of ACE I/D polymorphism genotypes in men with SA compared to controls, as well as in women with SA compared to controls. Also, there was a significant association between DD genotype and the risk of SA compared to II genotype as reference. The severity of depression was significantly different between DD and II genotypes in SA group. According to the results, we suggest that the presence of DD genotype is possibly associated with an increased risk of SA. Maybe part of that is related to severity of depression in DD genotypes carriers of ACE I/D polymorphism.

RESUMEN

Background: Despite studies about anxiety in the older adult, the prevalence of anxiety in this age group is not exactly clear, which may be due to the use of tools and criteria that were not born for this age group. One of the instruments designed to assess anxiety in the elderly is the Geriatric Anxiety Inventory (GAI). The aim of this research was to analyze the psychometric properties of the Persian version of the Geriatric Anxiety Inventory (GAI-PV) and its short form (GAI-PV-SF) in a sample of older adults in Iran. Methods: In this cross-sectional study, a sample of 150 community-dwelling and a psychogeriatric sample of 48 adults older than 60 years completed the GAI-PV and GAI-PV-SF, the anxiety sub-scale of the General Health Questionnaire (GHQ-28), the Geriatric Depression Scale (GDS-15), and the Structured Clinical Interview for DSM-IV (SCID-I). Different types of validity and reliability were evaluated for GAI-PV and GAI-PV-SF using SPSS and the LISREL software. Results: Both the GAI-PV and GAI-PV-SF exhibited excellent internal consistency (over 80 %) and desirable concurrent validity against GHQ-28 and GDS-15. The optimal cutpoint score to detect current generalized anxiety disorder (GAD) was 10/11 and 13/14 for GAI-PV in the community-dwelling and psychogeriatric samples, respectively, and 3/4 for GAI-PV-SF in both study samples. Good test-retest reliability (correlation coefficient: 0.96 and 0.88 for GAI-PV and GAI-PV-SF, respectively) and a single-factor structure were also demonstrated. Conclusion: Sound psychometric properties of the GAI-PV in both subsamples suggest that the instrument could be used successfully as an accurate screening instrument in the elderly Iranian population.

RESUMEN

Background: Smoking is considered as the second leading risk factor of early death and disability throughout the world. Smoking is the second leading risk factor of early death and disability in the world. The workplace is an important setting for the implementation of cigarette smoking prevention and control interventions. This study aimed to determine the prevalence of cigarette smoking and related factors by focusing on ADHD and risk-taking behaviors among a sample of Iranian workers. Methods: This cross-sectional study was conducted on 2434 male workers of Kaveh Industrial City in Saveh. Random cluster sampling was used in the selection of workers. All workers completed five sets of anonymous and validated questionnaires. ADHD was measured by Conner's Adult ADHD Rating Scales. Data analysis was done using chi-square, independent t-test and logistic regression model in STATA 10. Also, P-value <0.05 was considered statistically significant. Results: The mean age of the workers was 32.80±7.05 years. The prevalence of cigarette smoking in the lifetime, last year, last month, and daily or almost daily in the last month were 26.2%, 20.6% , 18.5%, and 13.1% respectively. After adjustment, age (OR=1.08), sensation seeking (OR=1.57), hookah smoking (OR=4.21), alcohol use (OR=2.51), sexual risk behaviors (OR=2.25), religiosity (OR=0.95) and self-esteem (OR=2.02) were associated with cigarette smoking. Conclusion: Our results showed that 13.1 % of workers were regular smokers (daily or almost daily). Specific programs in workplaces, including interventions to enhance self-steam and reduce anxiety, can be effective in lowering cigarette smoking prevalence. Also, comprehensive interventions to reduce or prevent different risk-taking behaviors can be considered as elements of preventive action plans.

RESUMEN

Background: According to the expansion of suicide prevention applications in recent years, the aim of this study was to review randomized controlled trials (RCTs) and pretest-posttest studies that evaluated the effectiveness of suicide prevention applications. Methods: In this systematic review, we searched online databases including Pubmed, SCOPUS, Web of Science, Chocrane Database, and Google Scholar to find randomized controlled trials and pretest-posttest studies published up to Jul 18, 2019. Randomized controlled trials and pretest-posttest of efficacy self-guided telephone applications that reported any primary and secondary outcome of suicidal thoughts and behaviors were included in the review. We evaluated the articles using the CONSORT 2010 checklist. Results: After screening articles, 7 studies were included in this review. Four studies focused on the effectiveness of applications on suicide thoughts and attempt, 2 on effectiveness of applications on self-injury, 4 on depression and anxiety, 1 on impulsivity, and 2 on adaptive strategies. Overall, mobile phone applications were associated with reductions in suicidal ideation scores at post intervention, and enhancement of adaptive skills; however, no evidence of reduction was reported in impulsivity after use of applications. Conclusion: Despite the differences in studies, this review showed that the use of mobile applications had an overall positive effect on reducing the risk of suicide and improving performance and health of patients.

RESUMEN

Background: It has been widely acknowledged that change and constant modification is the key to survive for any organization among their rivals. Since success in implementing changes in the organization strongly depends on the organizational culture, this study aims to assess the organizational culture in Iran University of Medical Sciences. The results of this study can be beneficial in initiating a movement towards the third - and fourth generation of universities. Methods: This study is descriptive-correlational. The Organizational Culture Assessment Instrument (OCAI) was employed to collect data. A questionnaire was sent to the faculty members via email, and the responses were collected and analyzed. Results: Out of the 982 faculty members, 189 participated (20.7%) in this study. Analysis showed that the organizational culture of the university is congruent and harmonious and in the current state, it is primarily hierarchical (31%) and market-oriented (28%) with emphasis on stability and control in the organization. Whereas, faculty members tend to move the organizational culture of the university towards adhocracy (30%) and clan culture (29%). Conclusion: University administrators must strengthen the culture of innovation and creativity based on the needs of the market. This only can be achieved by supporting teamwork in their move towards desired change.

RESUMEN

BACKGROUND: Self-medication is described as the use of drugs without a physician's prescription to treat self-recognized illness or symptoms, and an important health issue among the elderly. Despite the wide range of different definitions, recognizing all forms of self-medication among older adults, particularly, in developing countries, help healthcare professionals and providers to reduce harmful effects of self-medication. The purpose of this study is to describe the practice of self-medication and its related factors among elderly people in Iran based on the experiences of people who are involved in this phenomenon. METHODS: This qualitative study was conducted using content analysis. Purposive sampling was used to select the participants and continued until saturation. The participants were the elderly, their care-givers, physicians, and pharmacists. Data was collected using semi-structured interviews, and analysis was done using an inductive approach. The theory of planned behavior was used as a framework to explain the role of the emerged factors in the occurrence of self-medication behavior. RESULTS: Based on the expressed experiences of the participants, factors related to the practice of self- medication among the elderly in Iran fit in these 5 categories: "patient's attitudes towards disease, treatment, and physicians", "living with disease", "unfriendly environments", "enabling health system", and "influential others". CONCLUSIONS: Based on the results of this study, self-medication of the elderly in Iran has commonalities with many countries in regard to over-the-counter medications and complementary and alternative medicine; however, self-medication is also seen with drugs that require a prescription but can easily be obtained from pharmacies. Contributing factors, apart from the elderly themselves, include their families, caregivers, and social circle, the physical environment where they live, and the health system from which they receive services.

RESUMEN

BACKGROUND: Providing community-based mental health services is crucial and is an agreed plan between the Iranian Mental Health Office and the Regional Committee for the Eastern Mediterranean (affiliated with WHO). The aim of this study was to determine the effectiveness of home-visit clinical case-management services on the hospitalization rate and other clinical outcomes in patients with severe mental illness. METHODS: A total of 182 patients were randomly allocated into three groups, namely, home-visit (n=60), telephone follow-up (n=61) and as-usual care (n=61) groups. Trained nurses as clinical case-managers provided home-visit services and the telephone follow-up tasks. Hospitalization rate as a measure of recurrence, as well as burden, knowledge, general health condition of caregivers with positive/negative symptoms, satisfaction, quality of life, and social skills of the consumers were assessed as the main and secondary outcomes, respectively. RESULTS: Most clinical variables were improved in both intervention groups compared with the control group. During the one year follow-up, the rate of rehospitalization for the telephone follow-up and as-usual groups were respectively 1.5 and 2.5 times higher than the home-visit group. CONCLUSION: Trained clinical case-managers are capable of providing continuous care services to patients with severe mental illness. The telephone follow-up services could also have beneficiary outcome for the consumers, their caregivers, and the health system network.

RESUMEN

BACKGROUND: Implementing community-based psychiatric services is one of the priorities of the WHO/EMRO mental health programs. This study presents an aftercare service, as a community based-service, for patients with severe mental illness (SMIs). METHODS: In this randomized controlled clinical trial design, 176 patients, who attended selective hospitals with SMI, were allocated into three groups: clinical case managers provided by general practitioners, nurses and the control group (usual treatment). The clients and their caregivers received monthly home visits (education and treatment supervision). The effectiveness of the intervention was measured by indicators of psychopathology such as scores of YOUNG, caregivers' knowledge and satisfaction with the services. Health-related quality of life (SF-36) was considered as the primary outcome variable. Data were collected at baseline and at 12 months follow-up. Direct and indirect medical costs were obtained through a periodic completion of questionnaires and interviews by caregivers. Cost effectiveness ratio was estimated as cost per QALY gained in each group. SPSS 16.0 was used in this survey and statistical methods were chi-square, ANOVA, Scheffe as post-Hoc test and paired sample t-test with 95% confidence interval and 0.05 significance level. RESULTS: The results of our study revealed that the score of YOUNG, caregivers' knowledge and satisfaction with service were improved in both intervention groups after 12 months. Improvement in health-related quality of life was observed in the general practitioner and nurse group. The incremental cost effectiveness ratio was 5740807 IRR and 5048459 IRR per QALYs gained in the general practitioner and nurse groups, respectively. CONCLUSION: The model of aftercare services provided by trained nurses is the most cost- effective and feasible model for Iran's socio-economic conditions with low resource allocations.

RESUMEN

BACKGROUND: Suicide prevention is one of the priorities in policies of Iranian Ministry of Health and Medical Education (MHME). The suicide prevention program had two main parts of identifying and treatment of the depressed and suicide high risk individuals by Primary Health Care (PHC) network. The main aim of this study was to evaluate the results of integration of the program into PHC network in two cities with moderate to high rate of suicide with diverse socio-cultural backgrounds. METHODS: This work as a field trial study was conducted in Nahavand and Savojbolagh from April 2010 to March 2011 (12 months). A screening tool was designed. Required capacities such as treatment, referral and registration system were provided six months before the main study. The intervention phase (for one year) including the treatment process and five consultation sessions was conducted to identify depressed people and individuals with high risk of suicide. The data were analyzed by Chi square test. RESULTS: After one year of intervention, the rate of committing suicide became 4.98 and 3.36 per one hundred thousand population in Nahavand and Savojbolagh, respectively (16 and 1.6 per 100,000 in the year of before intervention respectively, 2009-2010). The female: male ratio of committing suicide was 2:1 in Nahavand and 1:1 in Savojbolagh. The most common method of committing suicide was drug intoxication in both cities. The identified cases by health workers at rural setting were 33 to 44 per 1000, in which 1.3 cases per 1000 population had been approved by general physicians. CONCLUSION: This study approved the feasibility and efficacy of integration of suicide prevention program into PHC. The increased rate of suicide in Savojbolagh could be related to low rate of screening and lack of treatment facilities (hospitalization and electroconvulsive therapy (ECT), and part-time psychiatrist. Increasing the PHC capacities could improve the health network efficiency to identify and manage depressed and at risk of suicide individuals. Screening tool/s and method have to be improved to provide better results.

RESUMEN

BACKGROUND: Major depression is a common disorder with great social and individual burdens. Transcranial sonography (TCS) is a useful and noninvasive measure for assessment of normal and impaired brain parenchyma. The brainstem raphe nuclei are in close association with dorsocaudal limbic system and plays an important role in depression. In this study we compared the echogenicity of the raphe nuclei in patients with major depressive disorder and the control group. METHODS: Thirty patients suffering from depression, diagnosed by a psychiatrist, and 30 cases of similar age and sex were entered into the case and control groups respectively. Semi-structural clinical conversation was done according to the DSM IV-TR in order to confirm the depression by the psychiatrist member of the group. Echogenicity of the brainstem raphe nuclei was assessed by a trained neurologist using TCS. To compare the mean echogenicity between the two groups independent sample t-test was used. In order to assess the strength of association between the disease and the echogenicity, odds ratio was also calculated. RESULTS: The echogenicity of the brainstem raphe nuclei was significantly decreased in depressed patients (36.7%) in comparison with the control group (10% ) (p= 0.015, OR= 5.21). CONCLUSION: Echogenicity of the brainstem raphe nuclei in patients with depression is significantly lower than normal population. To confirm the results, we recommend a meta analysis considering previous articles' results.

RESUMEN

Background: Deficits in problem-solving may be related to vulnerability to suicidal behavior. We aimed to identify the electroencephalographic (EEG) power spectrum associated with the performance of the Raven as a reasoning/problem-solving task among individuals with recent suicide attempts. Methods: This study with the case-control method, consisted of 61 participants who were assigned to three groups: Suicide attempt + Major Depressive Disorder (SA + MDD), Major Depressive Disorder (MDD), and Healthy Control (HC). All participants underwent clinical evaluations and problem-solving abilities. Subsequently, EEG signals were recorded while performing the Raven task. Results: The SA + MDD and MDD groups were significantly different from the HC group in terms of anxiety, reasons for life, and hopelessness. Regarding brain oscillations in performing the raven task, increased theta, gamma, and betha power extending over the frontal areas, including anterior prefrontal cortex, dlPFC, pre-SMA, inferior frontal cortex, and medial prefrontal cortex, was significant in SA + MDD compared with other groups. The alpha wave was more prominent in the left frontal, particularly in dlPFC in SA + MDD. Compared to the MDD group, the SA + MDD group had a shorter reaction time, while their response accuracy did not differ significantly. Conclusions: Suicidal patients have more frontal activity in planning and executive function than the two other groups. Nevertheless, it seems that reduced activity in the left frontal region, which plays a crucial role in managing emotional distress, can contribute to suicidal tendencies among vulnerable individuals. Limitation The small sample size and chosen difficult trials for the Raven task were the most limitations of the study.

RESUMEN

BACKGROUND: Limited studies have examined psychometric properties of dementia screening tools in university-educated older adults. We aimed to examine this population's diagnostic accuracy of the Iranian version of Mini-Addenbrooke's Cognitive Examination (M-ACE). MATERIALS & METHODS: Eighty-seven participants with over 60 years with university education were divided into three groups: Major neurocognitive disorder, mild neurocognitive disorder, and healthy control. The Iranian version of M-ACE, the Mini-Mental State Examination (MMSE), the Geriatric Depression Scale (GDS), the Activities of Daily Living-Instrumental Activities of Daily Living (ADL-IADL) scale and Diagnostic and Statistical Manual of Mental Disorders 5th edition-Text Revision (DSM-5) were used. RESULTS: A high internal reliability of questionnaire was confirmed by Cronbach's alpha coefficient. One-way ANOVA and post hoc analysis confirmed a significant difference between study groups. The scores of M-ACE were found to have a high positive correlation with MMSE, IADL, ADL, and a moderate correlation with GDS. The optimal cutoff score of M-ACE to screen for mild and major neurocognitive disorders were 27.5 and 20.5, respectively. CONCLUSION: The M-ACE was a concise and reliable tool used to identify neurocognitive disorders in highly educated older adults, but they should be evaluated at a higher traditional cut score in earlier stages.

RESUMEN

BACKGROUND: Considering the limited information on suicide determinants, especially in low- and middle-income countries, the establishment and promotion of a suicide registration system are among the prominent strategies for suicide prevention programs around the world. The multicenter suicide registry is designed to collect standardized data from the two provinces of Iran according to the latest World Health Organization (WHO) guidelines. METHODS: The Suicidal Behavior Registration Program is a multicenter study designed in five stages, including literature review, infrastructure establishment, database design, training, data analysis, and examining opportunities and challenges. The research samples cases of suicide attempts and self-harm from hospitals in the provinces of Tehran and Ilam. RESULTS: The multicenter suicide registration program was carried out for 8 months in the two provinces of Tehran and Ilam. During the study period, data of 1382 people were registered, of which 7 cases in Ilam resulted in death. The study uncovered significant differences in socio-demographic, psychological status, and suicide characteristics in the two provinces. CONCLUSION: The design and implementation of the suicide registration program help researchers and policymakers make more innovative and effective interventions to prevent suicide by creating a comprehensive database of suicidal behavior determinants.
