Dose escalation during the first year of long-term opioid therapy for chronic pain

OBJECTIVE

To identify patient factors and health care utilization patterns associated with dose escalation during the first year of long-term opioid therapy for chronic pain.

DESIGN

Retrospective cohort study using electronic health record data.

SETTING

University health system.

SUBJECTS

Opioid naïve adults with musculoskeletal pain who received a new outpatient opioid prescription between July 1, 2011 and June 30, 2012 and stayed on opioids for 1 year.

METHODS

Mixed-effects regression was used to estimate patients' rate of opioid dose escalation. Demographics, clinical characteristics, and health care utilization for patients with and without dose escalation were compared.

RESULTS

Twenty-three (9%) of 246 patients in the final cohort experienced dose escalation (defined as an increase in mean daily opioid dose of ≥30-mg morphine equivalents over 1 year). Compared with patients without dose escalation, patients with escalation had higher rates of substance use diagnoses (17% vs 1%, P = 0.01) and more total outpatient encounters (51 vs 35, P = 0.002) over 1 year. Differences in outpatient encounters were largely due to more non face-to-face encounters (e.g., telephone calls, emails) among patients with dose escalation. Differences in age, race, concurrent benzodiazepine use, and mental health diagnoses between patients with and without dose escalation were not statistically significant. Primary care clinicians prescribed 89% of opioid prescriptions.

CONCLUSIONS

Dose escalation during the first year of long-term opioid therapy is associated with higher rates of substance use disorders and more frequent outpatient encounters, especially non face-to-face encounters.

Food Insecurity is Associated With Mortality Among U.S. Adults With Nonalcoholic Fatty Liver Disease and Advanced Fibrosis

BACKGROUND & AIMS

Food insecurity is a growing public health challenge in the United States (U.S.) and has been linked to nonalcoholic fatty liver disease (NAFLD) and advanced fibrosis. However, little is known of how food insecurity impacts mortality risk and health care utilization in chronic liver disease.

METHODS

Using a population-based cohort study of U.S. adults (≥20 years) in the National Health and Nutrition Examination Survey, 1999 to 2014, with NAFLD (estimated by the U.S. Fatty Liver Index) and advanced fibrosis (estimated by the NAFLD fibrosis score, aspartate aminotransferase-to-platelet ratio index, or Fibrosis-4 Index), food security was measured using the Department of Agriculture Food Security Survey Module. The primary outcome was all-cause mortality from National Death Index data and the secondary outcome was health care utilization, defined as ≥2 inpatient and ≥4 outpatient visits, with Cox and logistic regression, respectively, estimating associations between food insecurity and outcomes.

RESULTS

Of 34,134 eligible participants (mean age, 47 years; 51% women; 14% in poverty), 4816 had NAFLD and 1654 had advanced fibrosis, with food insecurity present in 28% and 21%, respectively. All-cause age-adjusted mortality was 12 per 1000 person-years among participants with NAFLD (food-secure, 11; food-insecure, 15) and 32 per 1000 person-years among advanced fibrosis participants (food-secure, 28; food-insecure, 50). In multivariable analyses, food insecurity was independently associated with higher mortality among participants with NAFLD (hazard ratio, 1.46; 95% confidence interval [CI], 1.08-1.97) and advanced fibrosis (hazard ratio, 1.37; 95% CI, 1.01-1.86) and greater outpatient health care utilization in participants with NAFLD (odds ratio, 1.32; 95% CI, 1.05-1.67).

CONCLUSIONS

Food insecurity is significantly associated with greater all-cause mortality in adults with NAFLD and advanced fibrosis. Interventions that address food insecurity among adults with liver disease should be prioritized to improve health outcomes in this population.

Assessing National Trends and Disparities in Ambulatory, Emergency Department, and Inpatient Visits for Inflammatory Bowel Disease in the United States (2005-2016)

BACKGROUND & AIMS

Patients with inflammatory bowel diseases (IBDs) require repeated health care encounters, although the focus of care differs when patients are seen in ambulatory, emergency department (ED), or inpatient settings. We examined contemporary trends and disparities in IBD-related health care visits.

METHODS

We used data from the National Ambulatory Medical Care Survey, the Nationwide Emergency Department Sample, and the National Inpatient Sample to estimate the total number of annual IBD-related visits from 2005 through 2016. We performed logistic regression analyses to test temporal linear trends. Slope and differences in distributions of patient demographics were compared across time and treatment settings.

RESULTS

From 2005 through 2016, approximately 2.2 million IBD-related ambulatory visits (95 CI, 1.9-2.5) occurred annually on average, increasing by 70.3% from the time period of 2005 to 2007 through the time period of 2008 to 2010, and decreasing by 19.8% from the time period of 2011 to 2013 through the time period of 2014 to 2016. An average of 115,934 IBD-related ED visits (95% CI, 113,758-118,111) and 89,111 IBD-related hospital discharges (95% CI, 87,416-90,807) occurred annually. Significant increases in the rate of IBD-related ED visits (3.2 visits/10,000 encounters; P < .0001) and hospital discharges (6.0 discharges/10,000 encounters; P < .0001) were observed from 2005 through 2016. The proportion of patients paying with private insurance decreased from 2005 through 2016, among all care settings. A greater proportion of young patients, patients with Crohn's disease, non-white patients, and patients with Medicare or Medicaid used hospital-based vs ambulatory services.

CONCLUSIONS

In an analysis of data from 3 large databases, we found that although IBD-related ambulatory visits stabilized to decreased from 2005 through 2016, rates of ED use and admission to the hospital have continued to increase with changes in patient demographics, over time and among care settings.

Association of general psychological factors with frequent attendance in primary care: a population-based cross-sectional observational study

Background

Whereas several studies have examined the association between frequent attendance in primary care and illness-specific psychological factors, little is known about the relation between frequent attendance and general psychological factors. Thus, the aim of this study was to investigate the association between being a frequent attender in primary care and general psychological factors.

Methods

Data were used from a large, population-based sample of community-dwelling individuals aged 40 and above in Germany in 2014 (n = 7,446). Positive and negative affect, life satisfaction, optimism, self-esteem, self-efficacy, and self-regulation were included as general psychological factors. The number of self-reported GP visits in the past twelve months was used to quantify frequency of attendance; individuals with more than 9 visits (highest decile) were defined as frequent attenders.

Results

Multiple logistic regressions showed that being a frequent attender was positively associated with less life satisfaction [OR: 0.79 (0.70–0.89)], higher negative affect [OR: 1.38 (1.17–1.62)], less self-efficacy [OR: 0.74 (0.63–0.86)], less self-esteem [OR: 0.65 (0.54–0.79)], less self-regulation [OR: 0.74 (0.60–0.91)], and higher perceived stress [OR: 1.46 (1.28–1.66)], after adjusting for sociodemographic factors, morbidity and lifestyle factors. However, frequent attendance was not significantly associated with positive affect and self-regulation.

Conclusions

The present study highlights the association between general psychological factors and frequent attendance. As frequent GP visits produce high health care costs and are potentially associated with increased referrals and use of secondary health care services, this knowledge might help to address these individuals with high needs.

Earlier Anti-TNF Initiation Leads to Long-term Lower Health Care Utilization in Crohn's Disease but Not in Ulcerative Colitis

BACKGROUND & AIMS

The timing of initiating biologic therapy in persons with Crohn's disease (CD) and ulcerative colitis (UC) is an area of ongoing controversy. In particular, there is concern that delaying the initiation of biologic therapy may lead to more treatment-resistant disease, which can result in more complications and hospitalizations.

METHODS

We used health administrative data from Manitoba, Canada to identify all persons with a new diagnosis of inflammatory bowel disease (IBD) between 2001 and 2018 who received tumor necrosis factor antagonists (anti-TNF) therapy and had at least 1 year of post anti-TNF initiation follow-up. We measured the rates of hospitalization, surgery, and outpatient visits, prior to and for up to 5 years following anti-TNF initiation. We compared the rates of these health care utilization outcomes between persons receiving anti-TNFs within 2 years following diagnosis and those receiving anti-TNFs more than 2 years following IBD diagnosis. We used inverse probability treatment weighting to adjust for baseline differences in risk between the 2 groups.

RESULTS

Among 742 persons with CD, early anti-TNF initiators had fewer IBD-specific and overall hospitalizations over the 5 years following the start of therapy. Incidence of resective surgery was also lower in earlier anti-TNF initiators with CD if the first year following initiation was excluded from the analysis. In 318 cases of UC, there was no impact of the timing of anti-TNF therapy on the rates of hospitalization and surgery.

CONCLUSIONS

Earlier administration of anti-TNF therapy is associated with reduced downstream health care resource utilization in CD, though these impacts are not evident in UC.

Urban-Rural Differences in Health Care Utilization for Inflammatory Bowel Disease in the USA, 2017

BACKGROUND

Urban-rural differences in IBD-specific health care utilization at the national level have not been examined in the USA.

AIMS

We compared urban and rural rates of IBD-related office visits and IBD-specific (Crohn's disease (CD) or ulcerative colitis (UC)) hospitalizations and emergency department (ED) visits.

METHODS

From multiple national data sources, we compared national rates using Z test and compared estimates of patient and hospital characteristics and hospitalization outcomes between urban and rural areas using Chi-square and t tests.

RESULTS

In 2015 and 2016, digestive disease-related office visit rates, per 100 adults, were 3.1 times higher in urban than in rural areas (8.7 vs 2.8, P < 0.001). In 2017, age-adjusted rates per 100,000 adults were significantly higher in rural than urban areas for CD-specific hospitalizations (26.3 vs 23.6, P = 0.03) and ED visits (49.3 vs 39.5, P = 0.002). Compared with their urban counterparts, rural adults hospitalized for CD or UC in 2017 were more likely to be older and non-Hispanic white, have lower household income, Medicare coverage, and an elective admission, and were discharged from hospitals that were large, non-federal government owned, and in the Midwest or South. There were no significant urban-rural differences in length of stay and 30-day readmission rate.

CONCLUSIONS

While IBD or digestive disease-related office visit rates were lower in rural compared to urban areas, CD-specific hospitalization and ED visit rates were higher. Strategies that improve office-based care among rural patients with IBD may help to avoid more costly forms of health care use.

Epidemiologic Burden and Projections for Eosinophilic Esophagitis-Associated Emergency Department Visits in the United States: 2009-2030

BACKGROUND & AIMS

Patients with poorly controlled eosinophilic esophagitis (EoE) may require unplanned emergency department (ED) visits for the management of dysphagia or food impactions. We evaluated the epidemiologic burden of EoE on ED utilization in the United States.

METHODS

Data from the US Nationwide Emergency Department Sample were used to estimate weighted annual EoE-associated ED visits from 2009 to 2019. Temporal trends in population-adjusted rates of EoE visits were assessed using joinpoint regression. Autoregressive integrated moving average models were used to project EoE-associated ED visits to 2030. We also evaluated endoscopic utilization, requirement for hospitalization, and ED-related charges in patients with EoE presenting to the ED.

RESULTS

A total of 11,125 unweighted (49,507 weighted) ED visits for EoE were included (69.0% male; mean age, 32.4 y). The annual volume of EoE-associated ED visits increased from 2934 (95% CI, 2437-3431) in 2009 to 8765 (95% CI, 7514-10,015) in 2019, and is projected to reach 15,445 (95% prediction interval, 14,672-16,218) by 2030. From 2009 to 2019, the number of EoE-associated ED visits increased by an average of 11.5% per year (95% CI, 10.3%-12.7%). The proportion of patients admitted to the hospital from the ED decreased from 25.6% in 2009 to 2011 to 14.0% in 2017 to 2019. Half of EoE patients presenting to the ED required an endoscopy, and nearly 40% required an esophageal foreign body removal. Total mean inflation-adjusted charges for an EoE-associated ED visit were $9025 US dollars in 2019.

CONCLUSIONS

The volume of EoE-associated ED visits tripled between 2009 and 2019 and is projected to further double by 2030. This represents a substantial burden of unanticipated health care resource utilization and highlights a potential opportunity to optimize outpatient EoE care.

Increased Patient Activation Is Associated with Fewer Emergency Room Visits and Hospitalizations for Pain in Adults with Sickle Cell Disease

OBJECTIVE

Recurrent vaso-occlusive pain episodes, the most common complication of sickle cell disease (SCD), cause frequent health care utilization. Studies exploring associations between patient activation and acute health care utilization for pain are lacking. We tested the hypothesis that increased activation and self-efficacy are associated with decreased health care utilization for pain in SCD.

METHODS

In this cross-sectional study of adults with SCD at a tertiary medical center, we collected demographics, SCD phenotype, Patient Activation Measure levels, and self-efficacy scores using structured questionnaires. We reviewed charts to obtain disease-modifying therapy and acute health care utilization, defined as emergency room visits and hospitalizations, for vaso-occlusive pain episodes. Negative binomial regression analyses were used to test the hypothesis.

RESULTS

We surveyed 67 adults with SCD. The median age was 27.0 years, 53.7% were female, and 95.5% were African American. Median health care utilization for pain over one year (range) was 2.0 (0-24). Only one-third of participants (38.8%) were at the highest activation level (median [range] = 3 [1-4]). Two-thirds (65.7%) of participants had high self-efficacy (median [range] = 32.0 [13-45]). Regressions showed significant association between health care utilization and activation (incidence rate ratio [IRR] = 0.663, P = 0.045), self-efficacy (IRR = 0.947, P = 0.038), and male sex (IRR = 0.390, P = 0.003). Two outliers with high activation, self-efficacy, and health care utilization also had addictive behavior.

CONCLUSIONS

Many individuals with SCD have suboptimal activation and reduced self-efficacy. Higher activation and self-efficacy were associated with lower health care utilization for pain. Additional studies are needed to evaluate interventions to improve activation and self-efficacy and reduce acute health care utilization for pain.

What are the Barriers to Antenatal Care Utilization in Rufisque District, Senegal?: a Bottleneck Analysis

BACKGROUND

This study aimed to analyze the barriers affecting the utilization of antenatal care (ANC) among Senegalese mothers.

METHODS

Health facility staffs were surveyed to examine the availability coverage of ANC (infrastructural capacity of health posts to handle maternal and newborn healthcare). A total of 113 women of childbearing age were surveyed to identify factors associated with the accessibility coverage (physical, economic, and information accessibility factors), acceptability coverage (socio-cultural features, social acceptance, and language), and effectiveness coverage (ratio of mothers having completed 4 visits) of ANC. Further, to identify the socio-cultural factors and the specific characteristics of the barriers, 5 focus group discussions were conducted with women of childbearing age, their husbands and mothers-in-law, community health workers, and health facility staff. The effectiveness coverage of ANC was analyzed by reviewing materials from the District Health Information System 2 of Senegal.

RESULTS

Key barriers of ANC utilization were associated with acceptability coverage. ANC during early pregnancy was avoided owing to the negative social stigma surrounding miscarriage. The survey results indicated an extremely high miscarriage rate of 30.9% among the participants. The social stigma towards unmarried mothers caused them to hide their pregnancy, which deterred ANC utilization. The husband was the final decision maker and social supporter on ANC utilization.

CONCLUSION

To promote the utilization of ANC services among pregnant women in Senegal, it is important to alleviate the social stigma towards miscarriages and unmarried mothers, and to provide greater social support for pregnancies and newborn deliveries within family.

The Effect of Health Insurance on the Utilization of Health Services: A Systematic Review and Meta-Analysis

Insurance organizations are among the most influential organizations in the health system, which can lead to healthcare efficiency and patient satisfaction in case they are increasingly accessed. The main purpose of the present systematic review was to examine the effect of health insurance on the utilization of health services and also to examine the factors affecting it. The present study was a systematic review that aimed to examine the effect of health insurance on the utilization of health care services. The study was conducted in 2016 using Scopus, PubMed, Web of Science, Science Direct, and ProQuest databases. We examined the utilization rate of health insurance in insured people. The inclusion and exclusion criteria were included based on review and meta-analysis purposes. The utilization of health services increased for inpatient and outpatient services. The utilization rate of inpatient services increased by 0.51% whereas the utilization rate of outpatient services increased by 1.26%. We classified the variables affecting the utilization rate of insurance into three main categories and sub-categories: demographic variables of the household, socioeconomic status, and health status. Our study showed that insured people increased the utilization rate of health services, depending on the type of health services. Thus, health policymakers should consider the community's health insurance as a priority for health programs. For now, implementing universal health insurance is a good solution.

Clinical Characteristics, Health Care Utilization and Costs Among Men with Primary or Secondary Hypogonadism in a US Commercially Insured Population

INTRODUCTION

Hypogonadism is broadly associated with increases in chronic comorbid conditions and health care costs. Little is known about the specific impact of primary and secondary hypogonadism on health care costs.

AIM

To characterize the health care cost and utilization burden of primary and secondary hypogonadism in a population of US men with commercial insurance.

METHODS

Newly diagnosed patients with International Classification of Diseases, Ninth Revision, Clinical Modification codes associated with specific medical conditions known to have a high prevalence of testosterone deficiency (ie, relating to primary or secondary hypogonadism) or who had fills for testosterone replacement therapy from January 1, 2007 through April 30, 2013 were identified in administrative claims data from the HealthCore Integrated Research Database. A cohort of patients without hypogonadism was matched on demographics and comorbidities. The matched hypogonadism and non-hypogonadism cohorts (n = 5,777 in each cohort) were compared during a 12-month follow-up period.

MAIN OUTCOME MEASURES

Direct health care expenditures and utilization were assessed for all causes and for hypogonadism-related claims. Costs included out-of-pocket patient expenditures and those paid by the insurer.

RESULTS

Hypogonadism and matched non-hypogonadism cohorts were similar in demographics (mean age = 50 years) and diagnosed comorbid conditions in the 12 months preceding the index date. In the year after the index date, mean all-cause expenditures for patients with hypogonadism increased by 62% (from $5,425 to $8,813) compared with 25% for the matched controls (from $4,786 to $5,992; P < .01 for follow-up difference between groups). Approximately 16% of total mean costs ($1,377), primarily outpatient and pharmacy costs, were identifiable as related to hypogonadism.

CONCLUSION

These data from a population of US men with commercial insurance coverage showed a greater resource use burden for patients with primary and secondary hypogonadism compared with similar patients without hypogonadism. Additional management might be required to address unmet need and decrease the cost burden for patients with hypogonadism.

Current Situation of Home Oxygen Therapy for Chronic Obstructive Pulmonary Disease Patients in Korea

BACKGROUND

Long-term oxygen therapy provides various benefits, including prolonged survival for severely hypoxic chronic obstructive pulmonary disease (COPD) patients. However, adequate management strategies for home oxygen therapy are not well established in Korea. This study aimed to explore the current situation of home oxygen therapy to provide basic data for developing a strategy for COPD patients on home oxygen therapy.

METHODS

In this cross-sectional study, we enrolled COPD patients using home oxygen therapy for at least 1 month. Face-to-face interviews were conducted, guided by a structured questionnaire about home oxygen therapy.

RESULTS

A total of 195 patients were enrolled. The mean age was 72.6 ± 9.7 years, and 76.4% of patients were men. The mean modified Medical Research Council, COPD Assessment Test, and EuroQol-5D index scores were 3.4 ± 0.8, 29.7 ± 6.8, and 0.35 ± 0.44, respectively. At rest, patients were prescribed oxygen for 12.5 ± 7.3 hr/day and used 12.9 ± 8.5 hr/day on average. During exercise, the mean duration of prescribed oxygen was 6.6 ± 4.3 hr/day, and the actual use was 1.1 ± 2.9 hr/day. A total of 25.6% of patients used ambulatory oxygen; with financial burden the main reason for nonuse. The mean number of hospitalizations and emergency room visits were 2.5 and 2.6, respectively.

CONCLUSION

This study revealed low adherence to home oxygen therapy, poor health-related quality of life, frequent hospitalizations, and a high financial burden among COPD patients using home oxygen therapy. The study highlights the need for adequate strategies to improve the quality of home oxygen therapy.

Preliminary exploration of secondhand smoke exposure in youth with Sickle Cell Disease: biochemical verification, pulmonary functioning, and health care utilization

Exposure to secondhand smoke (SHSe) can compound an already challenging set of health problems for youth with Sickle Cell Disease (SCD). Exposure to electronic cigarettes may also impact SCD symptomology and respiratory functioning. This study built on these previous findings by a) utilizing two objective measures of SHSe, salivary cotinine and exhaled carbon monoxide and b) examining the association of SHSe with emergency department utilization, physician-reported sickle cell crises, and pulmonary functioning. Caregivers (N = 31 dyads; Mage = 37.6 years; SD = 8.5 years) of youth with SCD (Mage = 9.0 years; SD = 4.5 years) completed self-report measures of tobacco/nicotine use. Youth provided a saliva sample to assess cotinine levels, and performed pulmonary function tests. Dyads provided breath samples for measurement of eCO. A chart review was conducted to obtain medical history and utilization. Majority of youth (88%) were exposed to SHS via salivary cotinine. Interestingly, no significant associations were observed between youth cotinine levels and emergency department utilization, physician-reported sickle cell crises, or pulmonary functioning. Present findings indicate a need to assess for SHSe using objective assessment measures. Future research should investigate which specific factors contribute to increase SHSe/SHVe in youth with SCD.

Patient Factors Associated With Gastroesophageal Reflux Disease Diagnostic Evaluation Strategies: A Retrospective Cohort Study Using Real-World Evidence From a Large U.S. Medical Claims Database

Background and Aims

Barrett's esophagus (BE) screening is not highly utilized in the United States, and there are few data describing providers' approach to screening. To fill this gap and guide the implementation of future BE screening strategies, we studied evaluation practice patterns for gastroesophageal reflux disease (GERD) by nongastroenterologists.

Methods

We performed a retrospective cohort study of patients with chronic GERD using health claims data from the United States between 2005 and 2019. We used up to 5 years of data after the diagnosis of chronic GERD to determine patient factors associated with completion of a gastroenterology encounter. We also identified patient factors associated with whether the first gastroenterology encounter was a direct-access upper endoscopy or an office visit.

Results

We identified 484,023 patients diagnosed with chronic GERD by a nongastroenterology provider. The cumulative incidence of completing a gastroenterology encounter within 5 years was 38.7%. Gastrointestinal symptoms, such as dysphagia (adjusted hazard ratio [aHR] = 2.11, 95% confidence interval [CI] = 1.94-2.30), abdominal pain (aHR = 1.89, 95% CI = 1.85-1.94), and melena (aHR = 1.73, 95% CI = 1.65-1.82), were strongly associated with completion of a gastroenterology encounter. The patient factors strongly associated with direct-access upper endoscopy included dysphagia (aHR = 1.68, 95% CI = 1.52-1.85), weight loss (aHR = 1.46, 95% CI = 1.28-1.63), and melena (aHR = 1.42, 95% CI = 1.28-1.56).

Conclusion

A total of 38.7% of patients with chronic GERD complete a gastroenterology encounter within 5 years of diagnosis, and gastrointestinal alarm symptoms are the most strongly associated factors for receiving gastroenterology care. These findings highlight the importance of incorporating primary care providers in the development of new BE screening programs.

Cost of treatment among self-referred outpatients in referral hospitals compared to primary health care facilities in East Wollega, western Ethiopia: A comparative cross-sectional study

Patient self-referral is a condition when patients refer themselves to higher level health facilities without having to see anyone else first. Despite the expansion in the number of health facilities, it has been seen when patients routinely accessed referral hospitals without a formal referral. The study aims to evaluate cost of treatment among self-referred outpatients at referral hospitals compared to primary health care facilities. Comparative cross-sectional study design was used and the required sample size for the study was determined by using formula of double populations mean comparison cost of treatment for diseases leading to outpatient visits. A total of 794 participants (397 from referral hospital and 397 from primary health facilities) were included in the study. Data was collected using face-to-face interview from December 1 to 30, 2017. Data entry and analysis were made using SPSS version 20. Descriptive statistics and independent samples t-test were performed. A total of 783 outpatients responded to the interview of the study and 391 of them were from referral hospital and 392 from primary health facilities. The mean of outpatient visit cost per visit for the treatment of diseases leading to outpatient visits was significantly higher at referral hospitals compared to primary health facilities [95% CI=6.13 (5.07-7.18)] USD. The mean cost of outpatient visits for the treatment of all type of diseases leading to outpatient visits was significantly higher at referral hospitals and at least two times of primary level health facilities. Health care providers should create awareness in the community about referral linkages to inform patients and their families the additional costs they incur when they bypass the proximal primary health facilities.

Health equity in Iran: A systematic review

Background: Health inequities are among debatable and challenging aspects of health systems. Achieving equity through social determinants of health approach has been mentioned in most upstream national plans and acts in Iran. This paper reports the findings of a systematic review of the current synthesized evidence on health equity in Iran.

Methods: This is a narrative systematic review. The relevant concepts and terminology in health equity was found through MeSH. We retrieved the relevant studies from PubMed/MedLine, Social Sciences Database, and Google Scholar in English, plus the Jihad University Database (SID), and Google Scholar in Farsi databases from 1979 until the end of January 2018. The retrieved evidence has been assessed primarily based on PICOS criteria and then Ottawa-Newcastle Scale, and CASP for qualitative studies. We used PRISMA flow diagram and a narrative approach for synthesizing the evidence.

Results: We retrieved 172 455 studies. Following the primary and quality appraisal process, 114 studies were entered in the final phase of the analysis. The main part (approximately 95%) of the final phase included cross-sectional studies that had been analyzed through current descriptive inequality analysis indicators, analytical regression, or decomposition-based approaches. The studies were categorized within 3 main groups: health outcomes (40.3%), health utilization (32%), and health expenditures (27%).

Conclusion: As a part of understanding the current situation of health equity in the policymakers’ need to refer the retrieved evidence in this study, they need more inputs specially regarding the social determinants of health approach. It seems that health equity research plan in Iran needs to be redirected in new paths that give appropriate weights to biological, gene-based, environmental and contextbased, economic, social, and political aspects of health as well. We advocate addressing the aspects of Social Determinant of Health (SDH) in analyzing health inequalities.

Use of Primary Care Services, Care Specialized and Drug Use by Population 65 Years and More in the Community of Madrid, Spain

BACKGROUND

Ageing of the Spanish population results in an increase in health services required. Therefore, determine the frequency of the health services utilization in this age group and analyze their determinants has a great interest.The aim was to analyze the utilization of health services among older people living in two urban neighborhoods of northern Madrid.

METHODS

A cross-sectional population-based study. It is studied a cohort of 1327 individuals ≥ 65 years, stratified by age and sex. Nine utilization indicators were defined. For each indicator frequencies and the association of each with the other variables were calculated by multivariate analysis.

RESULTS

The distribution of indicators expressed as a percentage of the user population is: GP appoiments/month 64.8% (95%CI 62.3 to 67.4); nursing appoiments/month 44.6% (95% CI 41.2 to 47.2); home medical visits/month 3.1% (95%CI 2.2 to 4.1); home nursing visits/month 3% (95%CI 2.1 to 3.9); hospitalization/year 16.4% (95%CI 14.4 to 18.4); appoiments rheumatologist/orthopedic/year 25.1% (95%CI 22.7 to 27.4); physiotherapist appoiments/year 12.9% (95% CI 11.1 to 14.7); podiatrist appoiments/year 30.6% (95%CI 28.1 to 33.1) and polypharmacy (≥5 drugs) 55.7% (95% CI 53 to 58.4). Comorbidity was the best predictor of health care utilization ranging from OR 4.10 (95%CI: 3.07-5,49) to OR 1.39 (95%CI: 0.97-1.99) in polymedicated and visit the physiotherapist respectively. Cardiovascular disease (OR 1.34; 95%CI 1.03-1,76) and diabetes (OR 1.46; 95%CI: 1.05 -2.02) were independently associated with increased use of family doctor. Dependence was the main determinant for home healthcare (OR 3.38; 95%CI: 1.38-8.28) and nurses (OR 9.71; 95%CI: 4.19-22.48) Mood disorders were associated to polypharmacy (OR 2.06; 95%CI: 1,48-2.86) and to visits to family doctor (OR 1.52; 95%CI: 1,13-2.04).

CONCLUSIONS

The comorbidity is the strongest predictor of health services utilization. Cardiovascular diseases and diabetes are independently associated to greater use. Dependence is the main determinant of home care. Mood disorders associated with polypharmacy and increased attendances to the General Practitioner.

Chronic Pelvic Pain Profiles in Women Seeking Care in a Tertiary Pelvic Pain Clinic

OBJECTIVE

Female chronic pelvic pain (CPP) has multiple pain generators and significant psychosocial sequalae. Biopsychosocial-based phenotyping could help identify clinical heterogeneity that may inform tailored patient treatment. This study sought to identify distinct CPP profiles based on routinely collected clinical information and evaluate the validity of the profiles through associations with social histories and subsequent health care utilization.

METHODS

Women (18-77 years, n = 200) seeking care for CPP in a tertiary gynecological pelvic pain clinic between 2017 and 2020 were included. Baseline data of pain intensity, interference, catastrophizing, acceptance, overlapping pelvic pain syndromes, and co-occurring psychiatric disorders were subject to a partition around medoids clustering to identify patient profiles. Profiles were compared across social history and subsequent treatment modality, prescribed medications, and surgeries performed.

RESULTS

Two profiles with equal proportion were identified. Profile 1 was vulvodynia and myofascial pelvic pain-dominant characterized by lower pain burden and better psychological functioning. Profile 2 was visceral pain-dominant featuring higher pain interference and catastrophizing, lower pain acceptance, and higher psychiatric comorbidity. Patients in Profile 2 had 2-4 times higher prevalence of childhood and adulthood abuse history (all P < .001), were more likely to subsequently receive behavioral therapy (46% vs 27%, P = .005) and hormonal treatments (34% vs 21%, P = .04), and were prescribed more classes of medications for pain management (P = .045) compared to patients in Profile 1.

CONCLUSIONS

Treatment-seeking women with CPP could be separated into two groups distinguished by pain clusters, pain burden, pain distress and coping, and co-occurring mental health disorders.

Acculturation, Perceptions about Seeking Mental Health Care, and Utilization of Mental Health Services among US-based South Asians

Objectives

To examine the relationship between acculturation, cultural perceptions surrounding mental health (MH) burden and utilization of MH services among South Asian (SA) adults in the United States.

Design

Cross-sectional study.

Setting

Online survey.

Participants

Four hundred five SA adults (≥18 years old) residing in the United States.

Methods

Cross-sectional study of acculturation, attitudes toward MH burden, and MH service utilization was conducted via online survey. Multivariate logistic regression models were employed to understand how these factors were associated with MH service utilization.

Main outcome measure

Utilization of MH services.

Results

Among the 405 participants, 49.0% identified as immigrants (75.1% Indian, 8% Bangladeshi, 5.5% Pakistani, and 3.8% from other SA countries). Current utilization of MH services was associated with comfort conversing in English (odds ration [OR]=5.99; 95% confidence interval [CI]=1.63, 27.02), having English-speaking peers (OR=3.80; 95% CI=1.12, 12.93), and having family (OR=2.37; 95% CI=1.21, 4.64) and peers (OR=5.64; 95% CI=1.71, 18.66) who used MH services. Participants with mostly SA peers (OR=0.48; 95% CI=0.23, 0.97) reported lower lifetime MH service utilization, and those with positive perceptions about MH burden reported higher lifetime utilization (OR=1.04; 95% CI=1.01, 1.09).

Conclusions

Comfort expressing emotions in English, knowledge of family/peer MH service use, and type of social connections were associated with MH service utilization among SA immigrants. Interventions should aim to increase SA languages in which MH services are offered and to engage with SA communities to increase acceptance of MH service utilization.

Local Housing Choice Voucher Distribution Policies Impact Healthcare Utilization: a Randomized Natural Experiment

While associations between obtaining affordable housing and improved health care are well documented, insufficient funding often forces housing authorities to prioritize limited housing vouchers to specific populations. We assessed the impact of obtaining housing on health care utilization at two urban housing authorities with different distribution policies: Housing Authority A prioritized seniors and people with disabilities, while Housing Authority B prioritized medically complex individuals and families with school-aged children. Both housing authorities used random selection to distribute vouchers, allowing us to conduct a randomized natural experiment of cases and waitlisted controls. No significant demographic differences were present between those receiving vouchers and waitlisted controls. Housing Authority A vouchers were associated with increased outpatient visits (OR = 1.19; P = 0.051). Housing Authority B vouchers decreased the likelihood of emergency department visits (OR = 0.61; P = 0.042). This study provides evidence that, while obtaining housing can result in better health care outcomes overall, local prioritization policies can influence that impact.

Predicting a Risk of Transition to a Higher Level of Care for Home Support Service Recipients

This longitudinal, non-randomized, retrospective study uses the Kaplan-Meier estimates method and the Cox Proportional Hazard model to assess the risk of home support recipients' transitioning to a higher level of care after being hospitalized. The Kaplan-Meier survival analysis revealed that 50% of home support recipients were expected to move on to a higher level of care by day 1,374. The Cox Proportional Hazard model indicated that the risk of transitioning to a higher level of care increases by about 2% as a client ages by one year, and by about 10% if there were no emergency room visits in the last 12 months. Also, the risk will decrease by about 13% if an individual is getting more than one hour of home support service per visit on average, compared to those who are receiving less than one hour of home support services per visit. These results will help project long term home support demand and resource planning for home support and the health care system.
