Intensity Of Service Use Research Articles

The longitudinal dispositions of people diagnosed with adjustment or severe stress disorders

BackgroundAdjustment and stress-related disorders are prevalent among psychiatric service users. Despite their prevalence, little is known about their prognosis. To reduce that gap, the present article documents the service use and diagnostic outcomes of people with adjustment or stress-related disorders presenting at Singapore’s largest psychiatric emergency department.MethodsAdministrative data from 2014 to 2021 was retrieved to follow a group of 683 service users whose first-ever psychiatric presentation in 2014 warranted a diagnosis of adjustment or stress-related disorder. People were grouped a priori depending on whether different diagnoses were recorded within 7 days, 9 months, after 9 months or not at all. Survival curves characterized conversion to other diagnoses and engagement with healthcare services. Service use outcomes include the number of hospitalizations, outpatient appointments, emergency department visits, and prescriptions.ResultsSixty-one percent (n = 417) never received another diagnosis over the 8-year period. This group used emergency services most and received the most pharmacotherapy shortly after their first visit. Of those who received another diagnosis, depression, personality disorders, and psychotic disorders were the most common. Those who received another diagnosis within 7 days (n = 70, 10%) received it on their first day of hospitalization (IQR 1–1), making the most use of inpatient services. The group who received another diagnosis within 9 months (n = 105, 15%) did so after 42 days (IQR 26–84) and had the highest relative number of deaths. Those who received another diagnosis after 9 months (n = 91, 13%) did so after 1,134 days (IQR 613–1,823) and had the longest period of engagement but made the least use of any psychiatric service, potentially suggesting a group whose early index diagnosis heralded vulnerability to future disorders.ConclusionsA large group of service users with acute stress or adjustment disorders will likely never be given another psychiatric diagnosis and appear to disengage following an initial period of high-intensity service use. The group that received a different diagnosis after the 9-month mark had prolonged contact with services but low intensity of service use and may represent a target for preventative intervention to help them improve their stress-managing skills and avoid developing other disorders.

Tracking and Profiling Repeated Users Over Time in Text-Based Counseling: Longitudinal Observational Study With Hierarchical Clustering.

Due to their accessibility and anonymity, web-based counseling services are expanding at an unprecedented rate. One of the most prominent challenges such services face is repeated users, who represent a small fraction of total users but consume significant resources by continually returning to the system and reiterating the same narrative and issues. A deeper understanding of repeated users and tailoring interventions may help improve service efficiency and effectiveness. Previous studies on repeated users were mainly on telephone counseling, and the classification of repeated users tended to be arbitrary and failed to capture the heterogeneity in this group of users. In this study, we aimed to develop a systematic method to profile repeated users and to understand what drives their use of the service. By doing so, we aimed to provide insight and practical implications that can inform the provision of service catering to different types of users and improve service effectiveness. We extracted session data from 29,400 users from a free 24/7 web-based counseling service from 2018 to 2021. To systematically investigate the heterogeneity of repeated users, hierarchical clustering was used to classify the users based on 3 indicators of service use behaviors, including the duration of their user journey, use frequency, and intensity. We then compared the psychological profile of the identified subgroups including their suicide risks and primary concerns to gain insights into the factors driving their patterns of service use. Three clusters of repeated users with clear psychological profiles were detected: episodic, intermittent, and persistent-intensive users. Generally, compared with one-time users, repeated users showed higher suicide risks and more complicated backgrounds, including more severe presenting issues such as suicide or self-harm, bullying, and addictive behaviors. Higher frequency and intensity of service use were also associated with elevated suicide risk levels and a higher proportion of users citing mental disorders as their primary concerns. This study presents a systematic method of identifying and classifying repeated users in web-based counseling services. The proposed bottom-up clustering method identified 3 subgroups of repeated users with distinct service behaviors and psychological profiles. The findings can facilitate frontline personnel in delivering more efficient interventions and the proposed method can also be meaningful to a wider range of services in improving service provision, resource allocation, and service effectiveness.

The economic costs of orthopaedic services: a health system cost analysis of tertiary hospitals in a low-income country

BackgroundTraumatic injuries are rising globally, disproportionately affecting low- and middle-income countries, constituting 88% of the burden of surgically treatable conditions. While contributing to the highest burden, LMICs also have the least availability of resources to address this growing burden effectively. Studies on the cost-of-service provision in these settings have concentrated on the most common traumatic injuries, leaving an evidence gap on other traumatic injuries. This study aimed to address the gap in understanding the cost of orthopaedic services in low-income settings by conducting a comprehensive costing analysis in two tertiary-level hospitals in Malawi.MethodsWe used a mixed costing methodology, utilising both Top-Down and Time-Driven Activity-Based Costing approaches. Data on resource utilisation, personnel costs, medicines, supplies, capital costs, laboratory costs, radiology service costs, and overhead costs were collected for one year, from July 2021 to June 2022. We conducted a retrospective review of all the available patient files for the period under review. Assumptions on the intensity of service use were based on utilisation patterns observed in patient records. All costs were expressed in 2021 United States Dollars.ResultsWe conducted a review of 2,372 patient files, 72% of which were male. The median length of stay for all patients was 9.5 days (8–11). The mean weighted cost of treatment across the entire pathway varied, ranging from $195 ($136—$235) for Supracondylar Fractures to $711 ($389—$931) for Proximal Ulna Fractures. The main cost components were personnel (30%) and medicines and supplies (23%). Within diagnosis-specific costs, the length of stay was the most significant cost driver, contributing to the substantial disparity in treatment costs between the two hospitals.ConclusionThis study underscores the critical role of orthopaedic care in LMICs and the need for context-specific cost data. It highlights the variation in cost drivers and resource utilisation patterns between hospitals, emphasising the importance of tailored healthcare planning and resource allocation approaches. Understanding the costs of surgical interventions in LMICs can inform policy decisions and improve access to essential orthopaedic services, potentially reducing the disease burden associated with trauma-related injuries. We recommend that future studies focus on evaluating the cost-effectiveness of orthopaedic interventions, particularly those that have not been analysed within the existing literature.

Determinants of Telehealth Service Use among Mental Health Patients: A Case of Rural Louisiana.

The COVID-19 pandemic decreased the in-person outpatient visits and accelerated the use of telehealth services among mental health patients. Our study investigated the sociodemographic and clinical correlates of the intensity of telehealth use among mental health patients residing in rural Louisiana, United States. The study sample included 7069 telehealth visits by 1115 unique patients encountered from 1 April 2020 to 31 March 2021 at six mental health outpatient clinics managed by the Northeast Delta Human Services Authority (NEDHSA). We performed a negative binomial regression analysis with the intensity of service use as the outcome variable. Being younger, female, and more educated were associated with a higher number of telehealth visits. The prevalence of other chronic conditions increased telehealth visits by 10%. The telehealth service intensity varied across the nature of mental health diagnoses, with patients diagnosed with the schizophrenia spectrum and other psychotic disorders utilizing 15% fewer telehealth visits than patients diagnosed with depressive disorders. The promotion of telehealth services among mental health patients in the rural setting might require the elimination of the digital divide with a particular focus on the elderly, less educated, and those with serious mental health illnesses such as schizophrenia and psychotic disorders.

Profiles of high emergency department users with mental disorders.

This study aimed to (1) identify profiles of high emergency department (ED) users (3+ visits/year) among 5409 patients with mental disorders (MD) based on their patterns of ED use and clinical characteristics; (2) identify sociodemographic and service use correlates linked to high ED user profiles; and (3) assess risks of death in a 12-month follow-up period, controlling for sex and age. Using varied medico-administrative databases, this 5-year study collected patient data for six Quebec (Canada) ED. Latent class analysis was used to distinguish profiles of high ED users for a 3-year period, while bivariate analyses subsequently assessed associations between high ED user profiles and sociodemographic and service use correlates. Survival analysis were also applied to examine relationships between profile memberships of high ED users and risk of death in the 12 months following period of high ED use. Three profiles of high ED use were identified, Profile 1: 3-year recurrent very high ED users (10+ ED visits/year), Profile 2: 2-year recurrent high ED users, and Profile 3: 1-year high ED users. Profiles differed according to severity of health conditions, intensity of service use, particularly frequent hospitalizations, and risk of death: high in Profile 1, moderate in Profile 2, and low in Profile 3. Compared to 1-year high ED users, 3-year recurrent very high ED users and 2-year recurrent high ED users had poorer health and higher risk of death. More targeted interventions may be improved for especially recurrent high ED users and recurrent very high ED use.

Mental Health Spending and Intensity of Service Use Among Individuals With Diagnoses of Eating Disorders Following Federal Parity.

The Mental Health Parity and Addiction Equity Act (MHPAEA) was intended to eliminate differences in insurance coverage for mental health and substance use disorder services and medical-surgical care. No studies have examined mental health service use after federal parity implementation among individuals with diagnoses of eating disorders, for whom financial access to care has often been limited. This study examined whether MHPAEA implementation was associated with changes in use of mental health services and spending in this population. Using Truven Health MarketScan data from 2007 to 2012, this study examined trends in mental health spending and intensity of use of specific mental health services (inpatient days, total outpatient visits, psychotherapy visits, and medication management visits) among individuals ages 13-64 with a diagnosis of an eating disorder (N=27,594). MHPAEA implementation was associated with a small increase in total mental health spending ($1,271.92; p<.001) and no change in out-of-pocket spending ($112.99; p=.234) in the first year after enforcement of the parity law. The law's implementation was associated with an increased number of outpatient mental health visits among users, corresponding to an additional 5.8 visits on average during the first year (p<.001). This overall increase was driven by an increase in psychotherapy use of 2.9 additional visits annually among users (p<.001). MHPAEA implementation was associated with increased intensity of outpatient mental health service use among individuals with diagnoses of eating disorders but no increase in out-of-pocket expenditures, suggesting improvements in financial protection.

Examining the impact of migrant status on ethnic differences in mental health service use preceding a first diagnosis of schizophrenia

Some ethnic groups have more negative contacts with health services for first-episode psychosis, likely arising from a complex interaction between ethnicity, socio-economic factors, and immigration status. Using population-based health administrative data, we sought to examine the effects of ethnic group and migrant status on patterns of health service use preceding a first diagnosis of schizophrenia or schizoaffective disorder among people aged 14-35 over a 10-year period. We compared access to care and intensity of service use for first-generation ethnic minority groups to the general population of Ontario. To control for migrant status, we restricted the sample to first-generation migrants and compared service use indicators for ethnic minority groups to the European migrant group. Our cohort included 18,080 people with a first diagnosis of schizophrenia or schizoaffective disorder, of whom 14.4% (n=2607) were the first-generation migrants. Our findings suggest that the magnitude of ethnic differences in health service use is reduced and no longer statistically significant when the sample is restricted to first-generation migrants. Of exception, nearly, all migrant groups have lower intensity of primary care use, and Caribbean migrants are consistently less likely to use psychiatric services. We observed fewer ethnic differences in health service use preceding the first diagnosis of psychosis when patterns are compared among first-generation migrants, rather than to the general population, suggesting that the choice of reference group influences ethnic patterning of health service use. We need a comprehensive understanding of the mechanisms behind observed differences for minority groups to adequately address disparities in access to care.

Medicare's hospice benefit: analysis of utilization and resource use.

This work provides descriptive statistics on hospice users. It also explores the magnitude of relative resource use during hospice episodes and whether such patterns vary by episode length for patients who only use routine home care as compared to those who use multiple levels of hospice care. Examining resource use for hospice users who require different hospice levels of care within an episode versus solely routine home care provides insight to the varied resource use associated with the different patient populations (i.e., those who may require steady routine home care across the entire episode versus those who require varied levels of care across the episode). The analyses were based on a longitudinal analytic file that was constructed from 100% of Medicare claims for hospice users with completed episodes spanning September 1, 2008 through the end of calendar year 2011. In examining resource use for routine home care users and all levels of hospice care, the analyses were restricted to single episode decedents who began their hospice episode on or after April 1, 2010 and whose date of death was on or before December 31, 2011. Daily wage-weighted visit units (WWVUs) were calculated for each patient during their hospice stay. In order to compute a WWVU, one-fourth of the Bureau of Labor Statistics hourly wage rate for each visit discipline (i.e., skilled nursing, medical social services, home health aide, and an average for therapies) was multiplied by the corresponding number of visit units reported on hospice claims. Using enhanced data on the intensity of service use, the results confirm previous research that suggested a curved pattern to service use during a hospice episode. For several measures of resource intensity, service use is more intensive during the initial days in the episode and for the last few days prior to death relative to the middle days of the episode. The pattern becomes more pronounced as episodes increase in length, but is otherwise a similar curve when compared by diagnosis. Thus, the results provide useful information for potential policy discussions about Medicare hospice reform.

Utilization of long-term care services under the public long-term care insurance program in Korea: Implications of a subsidy policy

ObjectivesSouth Korea introduced public long-term care insurance (LTCI) in 2008. This study examined the patterns of and factors associated with public long-term care (LTC) utilization among older LTCI beneficiaries in Korea, with special attention to the policy for subsidizing the co-payments of lower income populations. MethodsUsing a 5% national representative sample of 280,290 older people aged 65 or older obtained from the 2010 national LTCI claims database, we examined socio-demographic and health factors associated with service utilization decisions, service type chosen, and the intensity of service use. ResultsAbout 5.48% of older adults in 2010 utilized the LTC provided under the Korean public LTCI, among which about 26.1% received a subsidy. Compared to their counterparts, the subsidized users were more likely to be low-income, female, and living alone. They were more likely to choose institutionalized care and spend to their monthly benefit limit while paying a lower co-payment. The factors associated with pattern and intensity of LTC utilization were not the same between subsidized and non-subsidized users. ConclusionThe findings imply the subsidy policy promotes equity of access to public LTC services. Further evaluation is necessary on the impact of the policy on the effectiveness of LTC utilization by socially marginalized populations.

Youth Characteristics Associated with Intensity of Service Use in a School-Based Mental Health Intervention

Several epidemiological studies have reported that large numbers of children and adolescents suffer from diagnosable psychiatric conditions, however most of them do not receive treatment. The schools are a key setting where youth with mental health problems are identified and linked to treatment. In this study we examine the demographic and clinical characteristics of youth referred to a school-based mental health intervention, the youth characteristics associated with continued participation in the intervention at 6-month follow up, and the youth characteristics that are associated with intensity of service use at 6-month follow up. The data were analyzed using descriptive frequencies, Chi-square tests and t tests, and bivariate and multivariable Poisson regressions. Demographic and clinical characteristics were not found to be significantly associated with discontinuing services before 6-months; however, several youth who discontinued services before 6-months had clinical characteristics suggesting a possible need for services. Youth demographic (sex, race) and clinical (diagnosis, suicidal ideation, alcohol/drug use, psychiatric medication use, and physical health) characteristics were significantly associated with intensity of service use in the multivariable analysis. This study underscores the importance of monitoring program participation, after the referral has been made and services have been accessed, to assure that youth participate in treatment long enough to obtain clinical benefits.

Variation between End-of-Life Health Care Costs in Los Angeles and San Diego: Why Are They So Different?

Small area differences in health care use between Boston, Massachusetts, and New Haven, Connecticut, are well known. However, we do not know whether factors believed to account for these variations explain differences between other geographic areas. To explore differences in health care use between the California counties of Los Angeles (LA) and San Diego. Medicare data were obtained form the Dartmouth interactive website. In addition, hospital-level data were obtained for the California Office of Statewide Health Planning and Development (OSPHD). Health outcomes and self-reported disease prevalence were estimated from the California Health Interview Survey (CHIS). Physician supply was comparable between LA and San Diego. Fees per unit service were also equivalent. Hospital beds beds per 10,000 population were 35% higher in LA. Intensity of service use, particularly during the last 2 years of life, was significantly higher in LA, and costs were dramatically higher. Most of the differences were explained by discretionary hospital admissions, end-of-life care, and lower use of hospice care. Quality indicators favor San Diego. Medical care, particularly at the end of life, is significantly more expensive in LA than in San Diego, yet quality measures tend to favor in San Diego. Non-emergent hospital admissions and inpatient care at the end of life are important contributors to the cost differences. There is little reason to believe that the greater spending for health care in LA results in better patient outcomes.

Market variations in intensity of Medicare service use and beneficiary experiences with care.

Examine associations between patient experiences with care and service use across markets. Medicare fee-for-service (FFS) and managed care (Medicare Advantage [MA]) beneficiaries in 306 markets from the 2003 Consumer Assessments of Healthcare Providers and Systems (CAHPS) surveys. Resource use intensity is measured by the 2003 end-of-life expenditure index. We estimated correlations and linear regressions of eight measures of case-mix-adjusted beneficiary experiences with intensity of service use across markets. We merged CAHPS data with service use data, excluding beneficiaries under 65 years of age or receiving Medicaid. Overall, higher intensity use was associated (p<.05) with worse (seven measures) or no better care experiences (two measures). In higher-intensity markets, Medicare FFS and MA beneficiaries reported more problems getting care quickly and less helpful office staff. However, Medicare FFS beneficiaries in higher-intensity markets reported higher overall ratings of their personal physician and main specialist. Medicare MA beneficiaries in higher-intensity markets also reported worse quality of communication with physicians, ability to get needed care, and overall ratings of care. Medicare beneficiaries in markets characterized by high service use did not report better experiences with care. This trend was strongest for those in managed care.

Population Patterns of Chronic Health Conditions, Co-morbidity and Healthcare Use in Canada: Implications for Policy and Practice

Managing chronic health conditions is a daily reality for approximately nine million Canadians, and the numbers of people affected are expected to increase as our population ages, particularly if risk factors that contribute to poor health continue to rise. These conditions impact health and well-being and represent a significant, and growing, healthcare and economic burden. The Health Council of Canada has focused its attention on the prevention and management of chronic conditions to encourage discussion of the changes to public policy, healthcare management and health services delivery required to improve health outcomes for Canadians. In December 2007, the Health Council released a report that described the health and healthcare use among Canadians who have chronic conditions as well as their self- reported experiences with chronic illness care. It highlighted initiatives under way in all jurisdictions to improve the situation. In order to inform that report, we analyzed population-based survey data from the Canadian Community Health Survey to report on patterns of health and healthcare use by community-dwelling youth and adults who have one or more of seven high-prevalence, high-impact chronic conditions. We demonstrated that the vast majority of people with chronic conditions have a regular medical doctor and visit community-based doctors and nurses frequently. Not surprisingly, people with chronic conditions use healthcare services more often and more intensively than do those without, and the intensity of service use increases as the numbers of conditions go up. The 33% of Canadians with one or more of seven chronic conditions account for approximately 51% of family physician/general practitioner consultations, 55% of specialist consultations, 66% of nursing consultations and 72% of nights spent in a hospital. This information highlights the imperative of immediate, comprehensive and sustained attention to undertake proven strategies to delay or prevent the onset of chronic conditions and to improve the quality of primary healthcare to prevent complications, reduce the need for more expensive health services and secure a better quality of life for Canadians.

The Use of Public Mental Health Services by Older Californians and Complementary Service System Effects

Older adults with mental disorders are less likely to use specialty care than any other population group. In this study, we created a multisource secondary data file and examined the use of public mental health services by older adults across California's county-based community mental health systems. We specifically considered complementary service system effects relative to compositional effects representing individual service users and more general contextual effects. Service use was defined in terms of treated prevalence rates, repeat service use, and intensity of service use. Differences across 49 county-based systems were evaluated by regressing the 3 service use measures onto compositional characteristics including client age, diagnosis, and insurance status; variables reflecting complementary service systems including mental health, health, long-term care, and aging services; and other contextual effects such as the size of the county population and average education level. The analyses were adjusted statistically for regional, yearly, and seasonal differences, and for longitudinal clustering within the 49 counties over 12 quarters of observation. Results suggested that older adults' service use varied significantly from one county to the next, and differences were associated with both compositional and contextual effects. As the aging population continues to grow and place an increasing demand on public mental health service systems, this research may help policy makers and program administrators understand some of the critical elements that affect service use patterns among older adults.

Medicaid Enrollment and Mental Health Service Use Following Release of Jail Detainees With Severe Mental Illness

Medicaid Enrollment and Mental Health Service Use Following Release of Jail Detainees With Severe Mental Illness

Medicare expenditures for residents in assisted living: data from a national study.

To provide preliminary data on Medicare expenditures for assisted living facility (ALF) residents and to investigate whether ALF characteristics were related to Medicare expenditures for ALF residents. Data from the National Study of Assisted Living for the Frail Elderly conducted in 1998-1999. This analysis was restricted to the 40 percent of ALFs in that sample that adhered to the assisted living (AL) philosophy by offering more than minimal levels of services and privacy. This study involved the approximately 1,200 residents who remained in an ALF from baseline to follow-up data collection. Six months of postbaseline Medicare claims were acquired for 545 of these residents, who did not differ significantly from the larger sample. Baseline individual and facility data were collected in personal interviews with residents and a combination of personal and telephone interviews with facility staff. Medicare claims data were acquired from the Centers for Medicare and Medicaid Services. Cross-sectional analyses using logistic and ordinary least squares regression techniques were used to determine the relationships among individual and facility characteristics and Medicare utilization and expenditures. On an annualized basis, AL residents incurred Medicare costs of approximately US dollars 4,800. Just less than 15 percent of AL residents accounted for over 75 percent of total Medicare costs. Both the likelihood of utilizing Medicare-covered services and the intensity of service use were largely unaffected by the characteristics of the ALF in which residents lived. Utilization was largely a function of individual characteristics. The only exception to this general finding was that those individuals who utilized services and resided in smaller ALFs had significantly lower average expenditures than did individuals in larger ALFs. These preliminary data imply that both the level and distribution of Medicare expenditures among ALF residents were similar to those among the general community-dwelling Medicare beneficiary population. No significant relationships were observed between ALF characteristics and Medicare expenditures, except the effect of facility size. This result may imply that how the AL industry eventually defines itself in terms of services and amenities, other than size, may have little impact on Medicare expenditures for ALF residents. However, this is a single, initial study, so caution must be exercised when considering the implications of these results.

Severity of injury and service utilization following traumatic brain injury: the first 3 months.

To describe the medical and rehabilitation service use of model systems by brain injured participants 1 to 3 months postdischarge from inpatient rehabilitation. Prospective follow-up study. Georgia Model Brain Injury System (GAMBIS). Seventy-three GAMBIS subjects consenting to participate in the utilization substudy. Receipt of services and intensity of service use. Chi-square analysis of receipt of services by severity of injury. The likelihood of service use did not vary with severity of injury. Data suggest that intensity of service use was a function of injury severity. Subjects with mild and moderate injuries were as likely to use a range of medical and rehabilitation services during the 3-month postdischarge period as those with severe injuries. Traditional rehabilitation services, such as physical therapy, were far more likely to be used, than nontraditional services, such as psychological counseling, in spite of the high level of cognitive and social disability associated with traumatic brain injury.

High service users in communal socio-psychiatric services

Differences in the intensity of social psychiatric care for mentally ill people are examined in two communal socio-psychiatric services in Saxony. Service users are subdivided into three groups according to intensity of service use (low utilization, average utilization and high utilization). The analyses are based on data from a standardized documentation system in a rural and urban catchment area. Intensity of care varies with structural parameters (geographical distance between patient home and service, staff resources). A small group (about 20 % of all clients) with a high frequency of contacts with service staff (high users) receive more than 50 % of all care contacts. Standardized documentation is a good basis for the description of different patterns of service utilization, but more information is needed about service users, e.g. data on their health care needs.
