[PMID: 36222088 DOI: 10.1080/21548331.2022.2134679] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/24/2022] [Accepted: 10/07/2022] [Indexed: 06/16/2023]
Abstract
OBJECTIVES This study aimed to investigate the viewpoints of the main stakeholders of the Iranian healthcare system about the overutilization of hospital services and strategies to eliminate or reduce it in Iran. METHODS This is a qualitative study and thematic data analysis using face-to-face semi-structured interviews and Focus Group Discussions (FGDs). We conducted eight interviewers and two FGDs with hospital stakeholders including faculty members, insurance organizations' authorities, experienced hospital administrative staff, hospital managers, and health-care providers. RESULTS The factors leading to the overutilization of hospital services were categorized into four main themes including site of service, quality, supplier push, and demand pull. Strategies for eliminating or reducing the overutilization of hospital services are also identified based on the influential factors. CONCLUSION Addressing overutilization of hospital services in the health system and adherence to policies for reducing or eliminating overutilization is a way to make preventive strategies to overcome overutilization. Developing a national plan to integrate utilization management into health system programs is a strategy to combat overutilization in various levels of the health system including hospital setting.

Strategies for utilisation management of hospital services: a systematic review of interventions. Global Health 2022; 18:53. [PMID: 35606776 PMCID: PMC9125833 DOI: 10.1186/s12992-022-00835-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/03/2022] [Accepted: 04/04/2022] [Indexed: 11/17/2022] Open
Abstract
Background To achieve efficiency and high quality in health systems, the appropriate use of hospital services is essential. We identified the initiatives intended to manage adult hospital services and reduce unnecessary hospital use among the general adult population. Methods We systematically reviewed studies published in English using five databases (PubMed, ProQuest, Scopus, Web of Science, and MEDLINE via Ovid). We only included studies that evaluated interventions aiming to reduce the use of hospital services or emergency department, frequency of hospital admissions, length of hospital stay, or the use of diagnostic tests in a general adult population. Studies reporting no relevant outcomes or focusing on a specific patient population or children were excluded. Results In total, 64 articles were included in the systematic review. Nine utilisation management methods were identified: care plan, case management, care coordination, utilisation review, clinical information system, physician profiling, consultation, education, and discharge planning. Primary case management was shown to effectively reduce emergency department use. Care coordination reduced 30-day post-discharge hospital readmission or emergency department visit rates. The pre-admission review program decreased elective admissions. The physician profiling, concurrent review, and discharge planning effectively reduced the length of hospital stay. Twenty three studies that evaluated costs, reported cost savings in the hospitals. Conclusions Utilisation management interventions can decrease hospital use by improving the use of community-based health services and improving the quality of care by providing appropriate care at the right time and at the right level of care.

Abstract
INTRODUCTION The provision of palliative end-of-life care (P/EOLc) for patients, wherever they live, is an increasingly important service, particularly given the increasing rates of cancer and other life-threatening diseases in Iran. However, unfortunately, those living in the rural areas of Iran are greatly disadvantaged with respect to this type of care. Therefore, the present study explored the feasibility of organizing P/EOLc in the rural areas of Iran. METHODS In this qualitative study, two focus group (FG) discussions were held in Tabriz (Iran) with rural family physicians (FPs, n=23) and key P/EOLc stakeholders (n=13). The FG sessions were recorded, transcribed, and the transcriptions checked by participants before the data were subjected to content analysis. RESULTS While most FPs indicated that they did not have sufficient involvement in providing P/EOLc, they emphasized the necessity of providing P/EOLc through four main themes and 25 subthemes. The four main themes were labeled as "structures and procedures," "health care provider teams," "obstacles," and "strategies or solutions." Furthermore, according to the main themes and subthemes identified here, the key stakeholders believed that the Iranian health system and the FPs' team have the potential to provide P/EOLc services in rural areas. CONCLUSION The most feasible strategy for providing P/EOLc in Iranian rural areas would be to use the current health care framework and base the process around the FP.

Abstract
Context: Most of the patients suffering from cancer are diagnosed at late stages of cancer, which curative interventions are unable to improve their quality of life. Aim: To survey Iranian physicians' attitudes and practices toward end-of-life (EOL) care. Subjects And Methods: We conducted a cross-sectional survey among physicians participating in a national annually conducted educational seminar. Results: The survey results show that 80% of physicians had between 1 and 3 EOL patients. About 72% of patients received medical care in hospitals. The difference in best setting for care of terminally ill patients was statically significant after controlling for the length of practice and physician belief. The results also showed that that the participants believed that that the level of physicians' knowledge in this field was unacceptable. Conclusion: Physicians of our study were interested to participating in continuing education programs focused on EOL patients.

Abstract
This study investigated the social capital of Iranian patients living with acquired immune deficiency syndrome (AIDS) and the associated factors. In a cross-sectional study the Integrated Social Capital Questionnaire was filled by a sequential sample of 300 patients visiting a referral counselling centre in Tehran. The patients' social capital scores were around 50% in the trust, social cohesion, collective action and cooperation and political empowerment domains. The groups and networks membership domain scored the lowest (27.1%). In regression analysis, employment status was significantly associated with groups and networks membership; age, marital status and financial status were associated with collective action and cooperation; period of disease awareness and marital status affected social cohesion and inclusion; and having risky behaviour affected empowerment and political action. Efforts are needed to enhance the social capital of those patients living with AIDS who are younger, unemployed, divorced/widowed, with risky behaviours and shorter disease awareness.

Abstract
Although most hepatitis C virus (HCV)-infected individuals develop chronic infection, about 25% of them are able to clear the virus spontaneously without any therapeutic intervention. The aim of the present study was to identify genes associated with spontaneous HCV clearance in a population of Iranian patients. We genotyped 110 single-nucleotide polymorphisms (SNPs) in 59 selected--candidate--genes in a cohort of 107 HCV-infected participants who spontaneously cleared the infection and 176 participants whose infection persisted. Three out of the 110 SNPs were found to be associated with HCV outcome (P-values<0.03). rs11506105 in EGFR (epidermal growth factor receptor gene), and rs11881222 and rs12979860 in IL28B (interferon-λ3 gene). Multivariate logistic regression of the three markers showed that the A/A genotypes in both rs11506105 (EFGR) and rs11881222 (IL28B), and the C/C genotype in rs12979860 (IL28B) are associated with HCV clearance (recessive model: odds ratio (OR)=2.06, 95% confidence interval (95% CI)=1.09-3.88, P=0.025; OR=2.09, 95% CI=1.23-3.60, P=0.007; and OR=1.95, 95% CI=1.15-3.35, P=0.014 for rs11506105, rs12979860 and rs11881222, respectively). In conclusion, EGFR and IL28B SNPs are strong independent predictive markers of spontaneous viral clearance.

Abstract
Context: Neonatal mortality rate is declining globally. The aim of the present study is to identify relevant indicators for assessing newborn care in hospitals by a systematic review. Evidence Acquisition: A search on electronic data base and manual searches of personal files for studies on quality indicators of newborn care were carried out. Searching 9 bibliographic databases, we found 85 articles of which 22 exactly related ones were selected and studied. Hand search yielded 1 record were also searched and 2 records were included. Results: A list of 87 structure, process and outcome indicators was formulated from the articles. Also 26 excess measures were identified in gray literature. After removing duplicates, and categorizing in 3 domains, 18 measures were input, 41 process and 34 outcome measures. Conclusions: These 93 indicators provide a framework for assessing how well the hospitals are providing neonatal care. These measures should be discussed in each context expert panels to address nationally applicable indices of neonatal care and may be adapted for local health settings.

Abstract
CONTEXT Due to expansion of chronic diseases and increase of health care costs, there is a need for planning and delivering hospice care for patients in their final stages of life in Iran. The aim of the present study is to investigate the knowledge and attitudes of nurses about delivering hospice care for End of Life (EOL) patients. MATERIALS AND METHODS This cross-sectional study was conducted in 2012 with a sample size of 200 nurses that were selected by convenient (available) sampling. The data collection instrument was a self-administered questionnaire whose validity was approved by experts' opinions and its reliability was approved by test-retest method. RESULTS Among all participants of this study, 87% were female. The mean age of nurses was 32.00 ± 6.72. From all respondents 62% stated that they have no knowledge about hospice care and 80% declared that need for hospice care is increasing. Most of the participants felt that, appropriate services are not presented to patients in the final stages of their lives. About 80% believed that hospice care leads to reduction of health care costs, improvement of physical, mental and social health of patients and finally improvement of the quality of health care services. There was a significant relationship between age, employment history and level of education of nurses and their attitude and knowledge about how this service is provided. CONCLUSION In view of the increase in chronic illnesses and the costs of caring, the need for provision of hospice care is felt more and more every day. However the awareness level of nurses about these services is low. Therefore the need for including these issues in nursing curriculum and holding scientific courses and seminars in this field is needed.

Abstract
BACKGROUND Following the implementation of family physician program in 2004 in Iranian healthcare system, the understanding in changes in physicians' practice has become important. OBJECTIVE The objective of this study was to determine the level of family physicians' job satisfaction and its relationship with their performance level. MATERIALS AND METHODS A cross-sectional study was conducted among all 367 family physicians of East Azerbaijan province in during December 2009 to May 2011 using a self-administered, anonymous questionnaire for job satisfaction. The performance scores of primary care physicians were obtained from health deputy of Tabriz Medical University. RESULTS In this study, overall response rate was 64.5%. The average score of job satisfaction was 42.10 (±18.46), and performance score was 87.52 (±5.74) out of 100. There was significant relationships between working history and job satisfaction (P = 0.014), marital status (P = 0.014), and sex (P = 0.018) with performance among different personal and organizational variables. However, there was no significant relationship between job satisfaction and performance, but satisfied people had about three times better performance than their counterparts (all P < 0.05). CONCLUSIONS The low scores of family physicians in performance and job satisfaction are obvious indications for more extensive research in identifying causes and finding mechanisms to improve the situation, especially in payment methods and work condition, in existing health system.

Abstract
Due to low efficacy in the field of a local commercial product of Bacillus thuringiensis M-H-14 (Bioflash(®)), a study was designed to assess its efficacy in laboratory, glass standard aquarium, semi-field and field conditions at both target and higher dosages against immature stages of Anopheles spp. and Culex spp. In laboratory conditions, the LC50 values of wettable powder and granule formulations were 227 and 1031 ppm respectively against a susceptible strain of An. stephensi. Following application of wettable powder and granules at 56.1 mg/aquarium, the survival rates of the exposed larvae to the granule formulation were 65.6% and 54.2% on days 6 and 8 respectively. In the artificial ponds, the larval density was reduced to 38.9%, 39.3% and 65.1% at dosages of 2, 4 and 8 g/m(2) respectively. In rice fields, at a dosage of 2 kg/ha, the density of immature larvae were reduced to 33.1% and 28.6% 7-days post-treatment. Further investigations are needed for the reasons for the low efficacy of this larvicide.

Abstract
Background and Aim: Iran's health sector has been engaging the services of physicians and midwives in healthcare centers since 2005, with the hope of improving the quantity and quality of family planning services. The aim of this study was to assess the effect of serving physicians and midwives on the quantity and quality of family planning services in the healthcare centers of Iran. Materials and Methods: The present cross-sectional study (Jan 2010 until Sep 2011) was carried out on 600 eligible families who were clients of healthcare centers of Tabriz, Azarshahr and Osku, cities of Northwest Iran from 2006 until 2011, in two groups (before and after). Some of the characteristics of the participants and the data on the quality and quantity of family planning services provided were grouped in a checklist of 16 variables by comparing the patients’ past medical histories. Results: In comparison with 3 years prior to engaging physician and midwife services in health care centers, the Couple Year Protection (CYP) and the quantity of family planning service indexes significantly increased among eligible families. The family size of participants declined significantly after family physicians and midwives became available in the healthcare centers (P < 0.005). Conclusion: Our findings showed some improvement in the quantity of services without any noticeable changes in the quality of services provided as a consequence of this huge intervention. Therefore, it is suggested that there should be proper oversight of the duties of the health team in order to keep a close watch on primary healthcare, design of proper mechanisms for collecting and maintaining performance reports and statistics, and continuously monitor and control the quality of services.

Abstract
BACKGROUND Maternal nutritional is the most important environmental factor influencing pregnancy outcome. While studies showed association between maternal iron-micronutrient deficiencies with pregnancy outcome, data examining impact of micronutrient supplementation on growth rate beyond birth are sparse. Present study examined the relationship between iron and multivitamins supplementation on growth rate of babies up to age of 18 month. METHODS This study was a statistical analysis on data recorded through a routine procedure in health houses from 1994 to 2007. Subjects were selected by a two-stage randomization method and required data extracted from the records. Analyses were performed using STATA 10 software. RESULTS Data was collected for 3835 pairs of mother-baby. Mothers received 61.7±5.4 and 115.6±53.8 multivitamins and iron tablets, respectively. Analyses showed significant relationship between children's weight and height at birth with iron supplementation and children's height at 6, 12 and 18 month with multivitamins supplementation. CONCLUSIONS Mechanisms of these effects are unclear but it is safe to suggest supplementation during pregnancy is necessary.

Abstract
Concerns about traditional chemical pesticides has led to increasing research into novel mosquito control methods. This study compared the effectiveness of 2 different types of polystyrene beads for control of mosquito larvae in south-east Islamic Republic of Iran. Simulated field trials were done in artificial pools and field trials were carried out in 2 villages in an indigenous malaria area using WHO-recommended methods. Application of expanded polystyrene beads or shredded, waste polystyrene chips to pool surfaces produced a significant difference between pre-treatment and post-treatment density of mosquitoes (86% and 78% reduction respectively 2 weeks after treatment). There was no significant difference between the efficacy of the 2 types of material. The use of polystyrene beads as a component of integrated vector management with other supportive measures could assist in the control of mosquito-borne diseases in the Islamic Republic of Iran and neighbouring countries.

Abstract
BACKGROUND Health-care-associated infections are a major threat to the safety of patient care. Control of such problem is a major criterion for hospital accreditation. This study was aimed to determine the developing use of chemical (class 6 products) and biological indicators in Tabriz district hospitals since 1997 to 2011. METHODS We conducted this time-trend interventional study with all of the public and private hospitals, which counted to 21 in Tabriz district as a sample. The situations of indicator use were presented for each time in the base of indicator groups. Furthermore, the results were showed in the base of hospital groups. RESULTS All of district hospital (n=21) with 74 autoclave machine and 22 central sterilization room were studied. The result of second time study in 2008 showed a markedly improvement in the control of sterilization processes. Furthermore, we continued our intervention results 6 month later in 2009 and 2 years later in 2011. The most striking result were use of chemical indicator in 100% of hospitals. However, there are defects in the use of biological indicators (63.65%). CONCLUSION The most obvious finding was significant improvement in sterilization control especially in development the use of chemical indicators. The finding of this study has a number of important implications for hospital managers and infection control practitioners such as continuous practical training of CSSD personnel in hospitals and mandating of indicator using in all sterilization process with controlling of this subject in evaluation and accreditation of hospital programs.

Abstract
Medical waste management (MWM) is an important public health concern worldwide. Although physicians must participate in medical waste management, their personal and organizational predictors in this process are unknown. This study aimed to the determinants of physicians' knowledge, attitudes and practices related to MWM in eight hospitals of Mazandaran province, northern Iran. A validated, reliable self-administered questionnaire was used including 30 questions about the respondents' knowledge, attitudes and practices (KAP) and personal and professional variables. Of a total of 200 physicians, 150 persons completed the questionnaire (response rate of 75%). The average score (± SD) for physicians' knowledge was 6.50 (± 1.50) out of 10, whereas those for attitudes and practices were 4.44 (± 0.88) and 4.02 (± 1.35) out of 5, respectively. Surgeons and orthopaedists had the lowest scores, whereas para-clinical specialists and internal medicine specialists had the highest scores. The score of knowledge showed significant differences among speciality groups and the various speciality groups' scores differed significantly only for knowledge (P = 0.024) and the mean of total KAP was significantly different between educational and non-educational hospitals (P < 0.05). As hospital type and physician speciality was related to the KAP concerning MWM, therefore it is recommend that all hospitals should develop appropriate protocols for medical waste management based on the this variables using a participatory process with teamwork and continuous training.

Abstract
We aimed to conduct an exposure assessment to dust and free silica for workers of Sangan iron ore mine in Khaf, Iran. The maximum concentrations of total dust and free silica were measured in crusher machine station at 801 ± 155 and 26 ± 7 mg/m(3), respectively. Meanwhile, the minimum concentrations were measured in official and safeguarding station at 8.3 ± 2 and 0.012 ± 0.002 mg/m(3), respectively. Also, the maximum concentrations of respirable dust and free silica were measured in Tappeh Ghermez drilling no. 1 at 66 ± 13 and 1.5 ± 0.4 mg/m(3), respectively, while the minimum concentrations were measured in pneumatic hammer at 5.26 ± 3 and 0.01 ± 0.005 mg/m(3), respectively. Considerate to Iranian standard for respirable dust concentrations (0.11 mg/m(3)) and international standards (ACGIH = 0.1 and NIOSH = 0.05 mg/m(3)), it was found that dust and free silica amounts were much higher than national and international standard levels in this mine.

Abstract
BACKGROUND & OBJECTIVES Jiroft district has subtropical climate and prone to seasonal malaria transmission with annual parasite index (API) 4.2 per 1000 in 2006. Anopheles stephensi Liston is a dominant malaria vector. The monitoring of insecticide susceptibility and irritability was conducted using discriminative dose as described by WHO. METHODS The IV instar larvae were collected from different larval breeding places and transported to the temporary insectary, fed with Bemax and then 2-3 days-old emerged and sugar-fed adults were used for susceptibility and irritability tests employing WHO methods and kits to organochlorine (OC) and pyrethroid (PY) insecticides. RESULTS Mortality rates of field strain of An. stephensi were 91.3 +/- 0.14 and 90 +/- 0.47% to DDT and dieldrin, respectively at one hour exposure time but was susceptible to all pyrethroids tested. The average number of take-offs per min per adult was 2.09 +/- 0.13 for DDT, 0.581 +/- 0.05 for dieldrin, 1.85 +/- 0.08 for permethrin, 1.87 +/- 0.21 for lambda-cyhalothrin, 1.53 +/- 0.13 for cyfluthrin, and 1.23 +/- 0.1 for deltamethrin. INTERPRETATION & CONCLUSION Currently, deltamethrin is being used for indoor residual spraying against malaria vectors in the endemic areas of Iran. The findings revealed that the main malaria species is susceptible to all pyrethroids including deltamethrin, permethrin, cyfluthrin and lambda-cyhalothrin but was tolerant to DDT and dieldrin. This report and the finding are coincided with results of previous studies carried out during 1957-61 in the same area. Irritability tests to OC and PY insecticides revealed the moderate level of irritability to DDT compared to pyrethroids and dieldrin. Monitoring for possible cross-resistance between OC and PY insecticides should come into consideration for malaria control programme.

Abstract
BACKGROUND Several genes coding for different cytokines may affect host susceptibility to tuberculosis. METHODS In the present study, the allele and genotype frequencies of a number polymorphic genes coding for cytokines or cytokine receptors were investigated in Iranian patients with pulmonary tuberculosis (PTB). RESULTS From the IL-1 cluster, a positive, significant difference was found at position -889, where the T/T genotype was over represented in PTB patients (p = 0.01); a positive, significant increase was found in the IL1R PstI 1970 C/C genotype, where the C allele was over represented in the PTB patients (p = 0.01). A significant negative association at codon 10 TGF-beta, T allele, was shown in our patients and the C allele and C/C genotype were over represented in the PTB patients (P<0.005). For TNF-alpha at position -238, we found a negative association for the G/A genotype and a positive association for the G/G genotype (p = 0.0009). Significant negative associations at position -590 IL-4, T allele and the T/T genotype were shown in our patients (p = 0.0007); also, the C allele and T/C genotype were significantly increased in our patients (P<0.05). With IL-6 at -174, G/G increased and G/C decreased significantly in the patients (P<0.005). CONCLUSION Pro-inflammatory cytokines such as TNF-alpha and TGF-beta seem to be decreased, and IL-6 increased in PTB patients.

Abstract
OBJECTIVES To investigate HLA-DRB1, DQA1 and DQB1 allelic polymorphism in Iranian patients with pulmonary tuberculosis (PTB). METHODS Forty patients with smear-positive PTB and 100 healthy individuals as a control group were studied for MHC class II allelic polymorphism by polymerase chain reaction with sequence-specific primers (PCR-SSP). The primer was supplied by biotest in the standard kit. DRB low resolution SSP and DQA, DQB intermediate resolution SSP was applied. RESULTS The comparison of the patients and the control group showed a significant increase in the frequency of the HLA-DRB1*07 and DQA1*0101 alleles (OR 2.7, 95%CI 1.19-6.13, P = 0.025 and OR 2.66, 95%CI 1.15-6.44, P = 0.04, respectively) in the patient group. The frequency of DQA1*0301 and DQA1*0501 was also significantly decreased (OR 0.254, 95%CI 0.075-0.865, P = 0.033 and OR 0.53, 95%CI 0.3-0.95, P = 0.045, respectively) in the PTB patients. Concerning haplotype frequency, DRB1*11501, QDQA1*0103 and DQB1*0601 were increased, but this difference was not statistically significant. In the DQB1 locus, DQB1*0501 was non-significantly over-represented. CONCLUSIONS HLA-DRB1*07 and HLA-DQA1*0101 appeared to be the predisposing alleles and HLA-DQA1*0301 and 0501 the protective alleles in our patients with TB.
