The Interplay Between Continuity of Care, Multimorbidity, and Adverse Events in Patients With Diabetes

Impact of COVID-19 Pandemic on Healthcare Utilization in People with Diabetes: A Time-Segmented Longitudinal Study of Alberta's Tomorrow Project

OBJECTIVE

The objective is to characterize the impact of COVID-19 on major healthcare for diabetes, including hospitalization, emergency department (ED) visits and primary care visits in Alberta, Canada.

METHODS

Participants from Alberta's Tomorrow Project (ATP) with pre-existing diabetes prior to 1 April 2018 were included and followed up to 31 March 2021. A time-segmented regression model was used to characterize the impact of COVID-19 on healthcare utilization after adjusting for seasonality, socio-demographic factors, lifestyle behaviors and comorbidity profile of patients.

RESULTS

Among 6099 participants (53.5% females, age at diagnosis 56.1 ± 9.9 y), the overall rate of hospitalization, ED visits and primary care visits was 151.5, 525.9 and 8826.9 per 1000 person-year during the COVID-19 pandemic (up to 31 March 2021), which means they reduced by 12% and 22% and increased by 6%, compared to pre-pandemic rates, respectively. Specifically, the first COVID-19 state of emergency (first wave of the outbreak) was associated with reduced rates of hospitalization, ED visits and primary care visits, by 79.4% (95% CI: 61.3-89.0%), 93.2% (95% CI: 74.6-98.2%) and 65.7% (95% CI: 47.3-77.7%), respectively. During the second state of emergency, healthcare utilization continued to decrease; however, a rebound (increase) of ED visits was observed during the period when the public health state of emergency was relaxed.

CONCLUSION

The declared COVID-19 states of emergency had a negative impact on healthcare utilization for people with diabetes, especially for hospital and ED services, which suggests the importance of enhancing the capacity of these two healthcare sectors during future COVID-19-like public health emergencies.

Patterns of inpatient acute care and emergency department utilization within one year post-initial amputation among individuals with dysvascular major lower extremity amputation in Ontario, Canada: A population-based retrospective cohort study

INTRODUCTION

Lower extremity amputation (LEA) is a life altering procedure, with significant negative impacts to patients, care partners, and the overall health system. There are gaps in knowledge with respect to patterns of healthcare utilization following LEA due to dysvascular etiology.

OBJECTIVE

To examine inpatient acute and emergency department (ED) healthcare utilization among an incident cohort of individuals with major dysvascular LEA 1 year post-initial amputation; and to identify factors associated with acute care readmissions and ED visits.

DESIGN

Retrospective cohort study using population-level administrative data.

SETTING

Ontario, Canada.

POPULATION

Adults individuals (18 years or older) with a major dysvascular LEA between April 1, 2004 and March 31, 2018.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

Acute care hospitalizations and ED visits within one year post-initial discharge.

RESULTS

A total of 10,905 individuals with major dysvascular LEA were identified (67.7% male). There were 14,363 acute hospitalizations and 19,660 ED visits within one year post-discharge from initial amputation acute stay. The highest common risk factors across all the models included age of 65 years or older (versus less than 65 years), high comorbidity (versus low), and low and moderate continuity of care (versus high). Sex differences were identified for risk factors for hospitalizations, with differences in the types of comorbidities increasing risk and geographical setting.

CONCLUSION

Persons with LEA were generally more at risk for acute hospitalizations and ED visits if higher comorbidity and lower continuity of care. Clinical care efforts might focus on improving transitions from the acute setting such as coordinated and integrated care for sub-populations with LEA who are more at risk.

Transfers between health facilities of people living with diabetes attending primary health care services in the Western Cape Province of South Africa: A retrospective cohort study

OBJECTIVES

Transfers between health facilities of people living with HIV attending primary health care (PHC) including hospital to PHC facility, PHC facility to hospital and PHC facility to PHC facility transfers occur frequently, affect health service planning, and are associated with disengagement from care and viraemia. Data on transfers among people living with diabetes attending PHC, particularly transfers between PHC facilities, are few. We assessed the transfer incidence rate of people living with diabetes attending PHC, and the association between transfers between PHC facilities and subsequent HbA1c values.

METHODS

We analysed data on HbA1c tests at public sector facilities in the Western Cape Province (2016-March 2020). Individuals with an HbA1c in 2016-2017 were followed-up for 27 months and included in the analysis if ≥18 years at first included HbA1c, ≥2 HbA1cs during follow-up and ≥1 HbA1c at a PHC facility. A visit interval was the duration between two consecutive HbA1cs. Successive HbA1cs at different facilities of any type indicated any transfer, and HbA1cs at different PHC facilities indicated a transfer between PHC facilities. Mixed effects logistic regression adjusted for sex, age, rural/urban facility attended at the start of the visit interval, disengagement (visit interval >14 months) and a hospital visit during follow-up assessed the association between transfers between PHC facilities and HbA1c >8%.

RESULTS

Among 102,813 participants, 22.6% had ≥1 transfer of any type. Including repeat transfers, there were 29,994 transfers (14.4 transfers per 100 person-years, 95% confidence interval [CI] 14.3-14.6). A total of 6996 (30.1%) of those who transferred had a transfer between PHC facilities. Visit intervals with a transfer between PHC facilities were longer (349 days, interquartile range [IQR] 211-503) than those without any transfer (330 days, IQR 182-422). The adjusted relative odds of an HbA1c ≥8% after a transfer between PHC facilities versus no transfer were 1.20 (95% CI 1.05-1.37).

CONCLUSION

The volume of transfers involving PHC facilities requires consideration when planning services. Individuals who transfer between PHC facilities require additional monitoring and support.

Reduced incidence of diabetes during the COVID-19 pandemic in Alberta: A time-segmented longitudinal study of Alberta's Tomorrow Project

AIM

To characterize the impact of the COVID-19 pandemic on diabetes diagnosis using data from Alberta's Tomorrow Project (ATP), a population-based cohort study of chronic diseases in Alberta, Canada.

MATERIALS AND METHODS

The ATP participants who were free of diabetes on 1 April 2018 were included in the study. A time-segmented regression model was used to compare incidence rates of diabetes before the COVID-19 pandemic, during the first two COVID-19 states of emergency, and in the period when the state of emergency was relaxed, after adjusting for seasonality, sociodemographic factors, socioeconomic status, and lifestyle behaviours.

RESULTS

Among 43 705 ATP participants free of diabetes (65.5% females, age 60.4 ± 9.5 years in 2018), the rate of diabetes was 4.75 per 1000 person-year (PY) during the COVID-19 pandemic (up to 31 March 2021), which was 32% lower (95% confidence interval [CI] 21%, 42%; p < 0.001) than pre-pandemic (6.98 per 1000 PY for the period 1 April 2018 to 16 March 2020). In multivariable regression analysis, the first COVID-19 state of emergency (first wave) was associated with an 87.3% (95% CI -98.6%, 13.9%; p = 0.07) reduction in diabetes diagnosis; this decreasing trend was sustained to the second COVID-19 state of emergency and no substantial rebound (increase) was observed when the COVID-19 state of emergency was relaxed.

CONCLUSIONS

The COVID-19 public health emergencies had a negative impact on diabetes diagnosis in Alberta. The reduction in diabetes diagnosis was likely due to province-wide health service disruptions during the COVID-19 pandemic. Systematic plans to close the post-COVID-19 diagnostic gap are required in diabetes to avoid substantial downstream sequelae of undiagnosed disease.

Impact of Care Fragmentation after Major Lower Extremity Amputation

BACKGROUND

Care fragmentation (CF) is a known risk factor for unplanned readmission, morbidity, and mortality after surgery. The goal of this study was to evaluate the impact of CF on outcomes of major lower extremity amputation for peripheral vascular disease.

METHODS

Health-care Cost and Utilization Project Database for NY (2016) and MD/FL (2016-2017) were queried using International Classification of Diseases 10thedition to identify patients who underwent above the knee-, through the knee-, and below the knee-amputation for peripheral vascular disease. Patients with CF were identified as those with admissions to ≥2 hospitals during the study period. We compared the postamputation outcomes of mortality, readmission rate, length of stay (LOS) and hospital charges.

RESULTS

We identified a total of 13,749 encounters of 2,742 patients who underwent major lower extremity amputations. There were 1,624 (59.2%) patients with CF. Patients with CF were younger (68.4 years old vs. 69.7 years old, P = 0.005), with higher Charlson Comorbidity Indices (4.4 vs. 4.1, P < 0.001), and required more hospital resources on index admission ($113,699 vs. $91,854, P < 0.001). These patients were prevalent for higher 30-, and 90-day readmission rates (34.7% vs. 24.5%, P < 0.001 and 54.7% vs. 42.0%, P < 0.001, respectively). On their first postamputation readmission, LOS (16.3 days vs. 14.7 days, P = 0.004) and hospital charge ($48,964 vs. $44,388, P = 0.002) were significantly higher. Multivariate regression analysis demonstrated that the CF was an independent predictor for 30-day (hazard ratio (HR) 1.65, 95% confidence interval (CI) 1.39-1.96, P < 0.001) and 90-day (HR 1.66, 95% CI 1.42-1.95, P < 0.001) readmission after the major lower extremity amputation, but not for mortality (HR 0.83, 95% CI 0.56-1.23, P = 0.36).

CONCLUSIONS

CF after major lower extremity amputation is associated with higher readmission rate, LOS, and hospital charge. Collaboration of care providers to maintain continuity of care for peripheral vascular disease patients may enhance quality of care and reduce health care cost.

Specialties Providing Ambulatory Care and Associated Health Care Utilization and Quality for Children With Medical Complexity

OBJECTIVE

Although children with medical complexity (CMC) have substantial health care needs, the extent to which they receive ambulatory care from primary care versus specialist clinicians is unknown. We aimed to determine the predominant specialty providing ambulatory care to CMC (primary care or specialty discipline), the extent to which specialists deliver well-child care, and associations between having a specialty predominant provider and health care utilization and quality.

METHODS

In a retrospective cohort analysis of 2012-17 all-payer claims data from Colorado, New Hampshire, and Massachusetts, we identified the predominant specialty providing ambulatory care for CMC <18 years. Propensity score weighting was used to create a balanced sample of CMC and assess differences in outcomes, including adequate well-child care, continuity of care, emergency visits, and hospitalizations, between CMC with a primary care versus specialty predominant provider.

RESULTS

Among 67,218 CMC, 75.3% (n = 50,584) received the plurality of care from a primary care discipline. Body system involvement, age > 2 years, urban residence, and cooccurring disabilities were associated with predominantly receiving care from specialists. After propensity score weighting, there were no significant differences between CMC with a primary care or specialist "predominant specialty seen" (PSS) in ambulatory visit counts, adequate well-child care, hospitalizations, or overall continuity of care. Specialists were the sole providers of well-child care and vaccines for 49.9% and 53.1% of CMC with a specialist PSS.

CONCLUSIONS

Most CMC received the plurality of care from primary care disciplines, and there were no substantial differences in overall utilization or quality based on the PSS.

The effect of the general practitioner as the first point of contact for care on the satisfaction with health care services in persons living with chronic spinal cord injury: A cross-sectional study

OBJECTIVE

The primary objective of this study was to investigate the effect of having a general practitioner (GP) as a first point of contact for care on the satisfaction with care services in persons with spinal cord injury (SCI), and how this effect is related to socio-demographic and health-related factors.

METHODS

This is a cross-sectional survey conducted within the framework of the Swiss Spinal Cord Injury Cohort Study Community Survey 2017. Outcome measures comprised three aspects of care (treatment with respect, understandability of explanations, and involvement in decision-making) and satisfaction with GP care and SCI centres. Information was grouped by first contact of care (GP or SCI specialist) and compared using the Mann-Whitney U test and logistic regression analysis.

RESULTS

Out of 3,959 invitees, 1,294 participants (33%) completed the survey. No significant association was found between the three aspects of care and the first contact of care. Persons who first contacted a GP and lived within a 10-minute travel distance to the GP practice were significantly less likely to be satisfied with their GP care (-5.7 percentage points, CI 95% = -10.7, -0.7), as compared to those living farther away. Persons who first contacted a GP rather than an SCI specialist were more likely to be satisfied with their GP care if married (7.1 percentage points, CI 95% = 1.4, 12.7), employed (6.6 percentage points, CI 95% = 0.9, 12.3), had a high social status (11.0 percentage points, CI 95% = 2.0, 20.1), or had tetraplegia (10.8 percentage points, CI 95% = 3.6, 18.1). For the same group, satisfaction with SCI centres was significantly higher in persons with good (10.1 percentage points, CI 95% = 0.1, 20.1) or very good health (8.2 percentage points, CI 95% = 1.0, 15.4), as compared to those with poor health.

CONCLUSION

The majority of participants were satisfied with the services offered by their first contact point for care, with variations due to factors endogenous to the participants. Socio-demographic and health-related factors should be integrated into health care planning strategies and improvement initiatives to ensure equitable access and better quality of health care services.

Impact of the family doctor system on the continuity of care for diabetics in urban China: a difference-in-difference analysis

OBJECTIVES

Our study aimed to examine whether the family doctor system can improve continuity of care for patients with diabetes.

DESIGN

Registry-based, population-level longitudinal cohort study.

SETTING

Linked data from the administrative Health Information System and the Health Insurance Claim Databases in a sample city in eastern China.

PARTICIPANTS

30 451 insured patients who were diagnosed with diabetes before January 2015 in the sample city, with ≥2 outpatient visits per year during 2014-2017. Diabetics in the intervention group had been registered with family doctor teams from 2015 to 2017, while those who had not registered were taken as the control group.

INTERVENTIONS

The family doctor system was established in China mainly to strengthen primary care and rebuild referral systems. Residents were encouraged to register with family doctors to obtain continuous health management especially for chronic disease management.

OUTCOME MEASURES

Continuity of care was measured by the Continuity of Care Index (COCI), Usual Provider Continuity Score (UPCS) and Sequential Continuity of Care Index (SECON) in 2014-2017.

RESULTS

COCI, UPCS and SECON of all diabetics in this study increased between 2014 and 2017. A difference-in-difference approach was applied to measure the net effect of the family doctor system on continuity of care. Our model controlled for demographic and socioeconomic characteristics, and severity of disease at baseline. Compared with the control group, diabetics registered with family doctors obtained an average 0.019 increase in COCI (SE 0.002) (p<0.01), a 0.016 increase in UPCS (SE 0.002) (p<0.01) and a 0.018 increase in SECON (SE 0.002) (p<0.01).

CONCLUSION

This study provides evidence that the family doctor system can effectively improve continuity of care for patients with diabetes, which has substantial policy implications for further primary care reform in China.

Characteristics and Health Care Use of Patients Attending Virtual Walk-in Clinics in Ontario, Canada: Cross-sectional Analysis

BACKGROUND

Funding changes in response to the COVID-19 pandemic supported the growth of direct-to-consumer virtual walk-in clinics in several countries. Little is known about patients who attend virtual walk-in clinics or how these clinics contribute to care continuity and subsequent health care use.

OBJECTIVE

The objective of the present study was to describe the characteristics and measure the health care use of patients who attended virtual walk-in clinics compared to the general population and a subset that received any virtual family physician visit.

METHODS

This was a retrospective, cross-sectional study in Ontario, Canada. Patients who had received a family physician visit at 1 of 13 selected virtual walk-in clinics from April 1 to December 31, 2020, were compared to Ontario residents who had any virtual family physician visit. The main outcome was postvisit health care use.

RESULTS

Virtual walk-in patients (n=132,168) had fewer comorbidities and lower previous health care use than Ontarians with any virtual family physician visit. Virtual walk-in patients were also less likely to have a subsequent in-person visit with the same physician (309/132,168, 0.2% vs 704,759/6,412,304, 11%; standardized mean difference [SMD] 0.48), more likely to have a subsequent virtual visit (40,030/132,168, 30.3% vs 1,403,778/6,412,304, 21.9%; SMD 0.19), and twice as likely to have an emergency department visit within 30 days (11,003/132,168, 8.3% vs 262,509/6,412,304, 4.1%; SMD 0.18), an effect that persisted after adjustment and across urban/rural resident groups.

CONCLUSIONS

Compared to Ontarians attending any family physician virtual visit, virtual walk-in patients were less likely to have a subsequent in-person physician visit and were more likely to visit the emergency department. These findings will inform policy makers aiming to ensure the integration of virtual visits with longitudinal primary care.

Qualitative study of pathways to care among adults with diabetes in rural Guatemala

OBJECTIVE

The burden of diabetes mellitus is increasing in low-income and middle-income countries (LMICs). Few studies have explored pathways to care among individuals with diabetes in LMICs. This study evaluates care trajectories among adults with diabetes in rural Guatemala.

DESIGN

A qualitative investigation was conducted as part of a population-based study assessing incidence and risk factors for chronic kidney disease in two rural sites in Guatemala. A random sample of 807 individuals had haemoglobin A1c (HbA1c) screening for diabetes in both sites. Based on results from the first 6 months of the population study, semistructured interviews were performed with 29 adults found to have an HbA1c≥6.5% and who reported a previous diagnosis of diabetes. Interviews explored pathways to and experiences of diabetes care. Detailed interview notes were coded using NVivo and used to construct diagrams depicting each participant's pathway to care and use of distinct healthcare sectors.

RESULTS

Participants experienced fragmented care across multiple health sectors (97%), including government, private and non-governmental sectors. The majority of participants sought care with multiple providers for diabetes (90%), at times simultaneously and at times sequentially, and did not have longitudinal continuity of care with a single provider. Many participants experienced financial burden from out-of-pocket costs associated with diabetes care (66%) despite availability of free government sector care. Participants perceived government diabetes care as low-quality due to resource limitations and poor communication with providers, leading some to seek care in other health sectors.

CONCLUSIONS

This study highlights the fragmented, discontinuous nature of diabetes care in Guatemala across public, private and non-governmental health sectors. Strategies to improve diabetes care access in Guatemala and other LMICs should be multisectorial and occur through strengthened government primary care and innovative private and non-governmental organisation care models.

Multimorbidity in Diabetic Patients Admitted to a Tertiary Care Center: A Descriptive Cross-sectional Study

INTRODUCTION

Multimorbidity is defined as the co-occurrence of two or more chronic conditions in the same individual. Type 2 Diabetes Mellitus rarely occurs without coexisting diseases. With an increasing elder population and longevity, elder adults have a higher prevalence of chronic morbidity, thus increasing the chances of experiencing more than one non-communicable chronic condition, where the impact of multimorbidity is greater than the cumulative effect of the single condition. The study aimed to find out the prevalence of multimorbidity in diabetic patients admitted to a tertiary care centre.

METHODS

A descriptive cross-sectional study was conducted utilising hospital records of patients with type 2 diabetes mellitus admitted to the Department of Medicine from 1 April 2021 to 1 April 2022. Ethical clearance was obtained from the Institutional Review Committee of the same institute (Reference number: 12082022/07). The diagnosed cases of type 2 diabetic patients aged more than 18 years and confirmed with serum glucose levels were included in the study. Convenience sampling was used. Point estimate and 95% Confidence Interval were calculated.

RESULTS

Out of the 107 diabetic patients, multimorbidity was present in 75 patients (70.10%) (61.42-78.77, 95% Confidence Interval).

CONCLUSIONS

The prevalence of multimorbidity is higher than the similar studies done in similar settings.

KEYWORDS

co-morbidity; diabetes mellitus; multimorbidity; osteoarthritis.

Personal continuity of GP care and outpatient specialist visits in people with type 2 diabetes: A cross-sectional survey

BACKGROUND

Continuity of care is particularly important for patients with chronic conditions, such as type 2 diabetes (T2D). Continuity is shown to reduce overall health service utilization among people with diabetes, however, evidence about how it relates to the utilization of outpatient specialist services in Norway is lacking. The aim of this study was to investigate continuity of GP care for people with T2D, and its association with the use of outpatient specialist health care services.

METHODS

We used e-mail questionnaire data obtained from members of The Norwegian Diabetes Association in 2018. Eligible for analyses were 494 respondents with T2D and at least one GP visit during the previous year. By descriptive statistics and logistic regressions, we studied usual provider continuity (UPC) and duration of the patient-GP relationship and associations of these measures with somatic outpatient specialist visits. Analyses were adjusted for gender, age, education, self-rated health, and diabetes duration.

RESULTS

Mean age was 62.6 years and mean UPC was 0.85 (CI 0.83-0.87). Two thirds of the sample (66.0%) had made all visits to the regular GP during the previous year (full continuity). Among these, 48.1% had made one or more specialist visits during the previous year, compared to 65.2% among those without full continuity. The probability of outpatient specialist visits was significantly lower among participants with full continuity, compared to those without full continuity (Odds Ratio 0.53, Confidence Interval 0.35-0.80). The probability of visiting outpatient specialist services was not associated with duration of the patient-GP relationship.

CONCLUSIONS

We conclude that continuity of care, as measured by Usual Provider Continuity, is high and associated with reduced use of somatic outpatient specialist services in people with T2D in Norway. Continuity and its benefits will become increasingly important as the number of older people with diabetes and other chronic diseases increases.

Economic evaluation of using polygenic risk score to guide risk screening and interventions for the prevention of type 2 diabetes in individuals with high overall baseline risk

Type 2 diabetes (T2D) with increasing prevalence is a significant global public health challenge. Obesity, unhealthy diet, and low physical activity are one of the major determinants of the rise in T2D prevalence. In addition, family history and genetic risk of diabetes also play a role in the process of developing T2D. Therefore, solutions for the early identification of individuals at high risk for T2D for early targeted detection of T2D, prevention, and intervention are highly preferred. Recently, novel genomic-based polygenic risk scores (PRSs) have been suggested to improve the accuracy of risk prediction supporting the targeting of preventive interventions to those at highest risk for T2D. Therefore, the aim of the present study was to assess the cost-utility of an additional PRS testing information (as a part of overall risk assessment) followed by a lifestyle intervention and an additional medical therapy when estimated 10-year overall risk for T2D exceeded 20% among Finnish individuals screened as at the high-risk category (i.e., 10%–20% 10-year overall risk of T2D) based on traditional risk factors only. For a cost-utility analysis, an individual-level state-transition model with probabilistic sensitivity analysis was constructed. A 1-year cycle length and a lifetime time horizon were applied in the base-case. A 3% discount rate was used for costs and QALYs. Cost-effectiveness acceptability curve (CEAC) and estimates for the expected value of perfect information (EVPI) were calculated to assist decision makers. The use of the targeted PRS strategy reclassified 12.4 percentage points of individuals to be very high-risk individuals who would have been originally classified as high risk using the usual strategy only. Over a lifetime horizon, the targeted PRS was a dominant strategy (i.e., less costly, more effective). One-way and scenario sensitivity analyses showed that results remained dominant in almost all simulations. However, there is uncertainty, since the probability (EVPI) of cost-effectiveness at a WTP of 0€/QALY was 63.0% (243€) indicating the probability that the PRS strategy is a dominant option. In conclusion, the results demonstrated that the PRS provides moderate additional value in Finnish population in risk screening leading to potential cost savings and better quality of life when compared with the current screening methods for T2D risk.

Association between continuity of care (COC), healthcare use and costs: what can we learn from claims data? A rapid review

Objective

To describe how longitudinal continuity of care (COC) is measured using claims-based data and to review its association with healthcare use and costs.

Research design

Rapid review of the literature.

Methods

We searched Medline (PubMed), EMBASE and Cochrane Central, manually checked the references of included studies, and hand-searched websites for potentially additional eligible studies.

Results

We included 46 studies conducted in North America, East Asia and Europe, which used 14 COC indicators. Most reported studies (39/46) showed that higher COC was associated with lower healthcare use and costs. Most studies (37/46) adjusted for possible time bias and discussed causality between the outcomes and COC, or at least acknowledged the lack of it as a limitation.

Conclusions

Whereas a wide range of indicators is used to measure COC in claims-based data, associations between COC and healthcare use and costs were consistent, showing lower healthcare use and costs with higher COC. Results were observed in various population groups from multiple countries and settings. Further research is needed to make stronger causal claims.

Continuity of care and multimorbidity in the 50+ Swiss population: An analysis of claims data

Objective

To assess the relationship between continuity of care (COC) and multimorbidity in the older general population in Switzerland, accounting for relevant determinants of COC, and to apply various expressions of multimorbidity derived from claims data.

Methods

We used data on 240'000 insured individuals aged 50+ for the period 2015-2018, received from one of the largest Swiss health insurance company. We calculated Bice-Boxerman index based on all doctor visits (overall COC) and visits to the general practitioners (COC GP). We analyzed the relationship between COC and multimorbidity using generalized linear and probit models. To express multimorbidity, we applied three approaches based on pharmacy-cost groups (PCGs) assigned to an individual. First, we used simple PCG counts. Second, we expressed multimorbidity via clinically relevant disease groups derived from PCGs. Finally, a data-driven approach allowed defining distinct clusters representing different patient complexities.

Results

The association between overall COC and multimorbidity expressed in PCG counts was modest: COC among individuals with 3+ PCGs was 2 percentage points higher than COC among individuals with 0 PCGs. The approach of clinically relevant disease groups showed larger variation in COC and its association with multimorbidity. The data-driven approach showed that most complex ("high-cost high-need") individuals tended to have higher overall COC. Additionally, 70% of the sample visited exclusively one general practitioner (COC GP = 1.0). Other important factors associated with COC in the Swiss context were insurance model with gatekeeping, level of deductibles, and region of residence.

Conclusions

Multimorbid patients require regular medical attention often involving multiple healthcare providers, which can lead to varying COC, depending on types of doctors seen and specific condition of the patient. Insurance models with gatekeeping may facilitate COC, prompting developments of better-designed models of care. This represents important implications for policymakers, health insurance representatives, medical professionals and hospital managers.

Multimorbidity and catastrophic health expenditure among patients with diabetes in China: a nationwide population-based study

INTRODUCTION

Multimorbidity is common among patients with diabetes and can lead to catastrophic health expenditure (CHE) for their families. This study aims to investigate the prevalence of multimorbidity and CHE among people with diabetes in China, and the association between multimorbidity and CHE and whether this is influenced by socioeconomic status and health insurance type.

METHODS

A national survey was conducted in China in 2013 that included 8471 people aged ≥18 years who were living with diabetes. The concentration curve and concentration index were used to measure socioeconomic-related inequalities. Factors influencing CHE and the impact of multimorbidity on CHE according to socioeconomic status and health insurance type were examined by logistic regression.

RESULTS

There were 5524 (65.2%) diabetes patients with multimorbidity. The prevalence of CHE was 56.6%, with a concentration index of -0.030 (95% CI -0.035 to -0.026). For each additional chronic disease, the probability of CHE increased by 39% (OR=1.39, 95% CI 1.31 to 1.47). Factors that were positively associated (p<0.05) with CHE included older age; male sex; lower educational level; being retired, unemployed or jobless; being a non-smoker and non-drinker; having had no physical examination; lower socioeconomic status; being in an impoverished family; and residing in the central or western regions. Among participants with Urban Employee Basic Medical Insurance, Urban Resident Basic Medical Insurance, and New Rural Cooperative Medical Scheme, the probability of CHE increased by 32% (OR=1.32, 95% CI 1.23 to 1.43), 43% (OR=1.43, 95% CI 1.24 to 1.65) and 47% (OR=1.47, 95% CI 1.33 to 1.63), respectively, with each additional chronic disease. The association between multimorbidity and CHE was observed across all health insurance types irrespective of socioeconomic status.

CONCLUSIONS

Multimorbidity affects about two-thirds of Chinese patients with diabetes. Current health insurance schemes offer limited protection against CHE to patients' families.

Type 2 Diabetes-Related Health Economic Impact Associated with Increased Whole Grains Consumption among Adults in Finland

The prevalence of type 2 diabetes (T2D) is increasing rapidly worldwide. A healthy diet supporting the control of energy intake and body weight has major importance in the prevention of T2D. For example, a high intake of whole grain foods (WGF) has been shown to be inversely associated with risk for T2D. The objective of the study was to estimate the expected health economic impacts of increased WGF consumption to decrease the incidence of T2D in the Finnish adult population. A health economic model utilizing data from multiple national databases and published scientific literature was constructed to estimate these population-level health economic consequences. Among the adult Finnish population, increased WGF consumption could reduce T2D-related costs between 286€ and 989€ million during the next 10-year time horizon depending on the applied scenario (i.e., a 10%-unit increase in a proportion of daily WGF users, an increased number (i.e., two or more) of WGF servings a day, or alternatively a combination of these scenarios). Over the next 20–30 years, a population-wide increase in WGF consumption could lead to much higher benefits. Furthermore, depending on the applied scenario, between 1323 and 154,094 quality-adjusted life years (QALYs) could be gained at the population level due to decreased T2D-related morbidity and mortality during the next 10 to 30 years. The results indicate that even when the current level of daily WGF consumption is already at a relatively high-level in a global context, increased WGF consumption could lead to important health gains and savings in the Finnish adult population.

Pharmacy-based screening to detect persons at elevated risk of type 2 diabetes: a cost-utility analysis

Background

Early identification of people at elevated risk of type 2 diabetes (T2D) is an important step in preventing or delaying its onset. Pharmacies can serve as a significant channel to reach these people. This study aimed to assess the potential health economic impact of screening and recruitment services in pharmacies in referring people to preventive interventions.

Methods

A decision analytic model was constructed to perform a cost-utility analysis of the expected national health economic consequences (in terms of costs and quality-adjusted life years, QALYs) of a hypothetical pharmacy-based service where people screened and recruited through pharmacies would participate in a digital lifestyle program. Cost-effectiveness was considered in terms of net monetary benefit (NMB). In addition, social return on investment (SROI) was calculated as the ratio of the intervention and recruitment costs and the net present value of expected savings. Payback time was the time taken to reach the break-even point in savings. In the base scenario, a 20-year time horizon was applied. Probabilistic and deterministic sensitivity analyses were applied to study robustness of the results.

Results

In the base scenario, the expected savings from the pharmacy-based screening and recruitment among the reached target cohort were 255.3 m€ (95% CI − 185.2 m€ to 717.2 m€) in pharmacy visiting population meaning 1412€ (95% CI − 1024€ to 3967€) expected savings per person. Additionally, 7032 QALYs (95% CI − 1344 to 16,143) were gained on the population level. The intervention had an NMB of 3358€ (95% CI − 1397€ to 8431€) using a cost-effectiveness threshold of 50,000 €/QALY. The initial costs were 122.2 m€ with an SROI of 2.09€ (95% CI − 1.52€ to 5.88€). The expected payback time was 10 and 8 years for women and men, respectively. Results were most sensitive for changes in effectiveness of the intervention and selected discount rate.

Conclusions

T2D screening and recruitment to prevention programs conducted via pharmacies was a dominant option providing both cost savings and QALY gains. The highest savings can be potentially reached by targeting recruitment at men at elevated risk of T2D.

Self-efficacy remains a vital factor in reducing the risk of dialysis in type 2 diabetes care

Studies have provided promising outcomes of the pay-for-performance (P4P) program or with good continuity of care levels in diabetes control.We investigate the different exposures in continuity of care (COC) with their providers and those who participate in the P4P program and its effects on the risk of diabetes diabetic nephropathy in the future.We obtained COC and P4P information from the annual database, to which we applied a hierarchical linear modeling (HLM) in 3 levels adjusted to account for other covariates as well as the effects of hospital clustering and accumulating time.Newly diagnosed type 2 diabetes in 2003At the individual level, those with a higher Diabetes Complications Severity Index (DCSI) score have a higher likelihood of diabetic nephropathy than those with a lower DCSI (OR, 1.46), whereas contrasting results were obtained for the Charlson Comorbidity Index (CCI) (odds ratio[OR], 0.88). Patients who visited family physicians, endocrinologists, and gastroenterologists showed a lower likelihood of diabetic nephropathy (OR, 0.664, 0.683, and 0.641, respectively), whereas those who continued to visit neurologists showed an increased risk of diabetic nephropathy by 4 folds. At the hospital level, patients with diabetes visiting primary care clinics had a lower risk of diabetic nephropathy with an OR of 0.584 than those visiting hospitals of other higher levels. Regarding the repeat time level, the patients who had a higher COC score and participated in the P4P program had a reduced diabetic nephropathy risk with an OR of 0.339 and 0.775, respectively.Diabetes control necessitates long-term care involving the patients' healthcare providers for the management of their conditions to reduce the risk of diabetic nephropathy. Indeed, most contributing factors are related to patients, but we cannot eliminate the optimal outcomes related to good relationships with healthcare providers and participation in the P4P program.

Effects of continuity of care on health outcomes among patients with diabetes mellitus and/or hypertension: a systematic review

BACKGROUND

The rising prevalence of non-communicable diseases (NCDs) such as diabetes mellitus (DM) and hypertension (HT) has placed a tremendous burden on healthcare systems around the world, resulting in a call for more effective service delivery models. Better continuity of care (CoC) has been associated with improved health outcomes. This review examines the association between CoC and health outcomes in patients with DM and/or HT.

METHODS

This was a systematic review with searches carried out on 13 March 2021 through PubMed, Embase, MEDLINE and CINAHL plus, clinical trials registry and bibliography reviews. Eligibility criteria were: published in English; from 2000 onwards; included adult DM and/or HT patients; examined CoC as their main intervention/exposure; and utilised quantifiable outcome measures (categorised into health indicators and service utilisation). The study quality was evaluated with Critical Appraisal Skills Programme (CASP) appraisal checklists.

RESULTS

Initial searching yielded 21,090 results with 42 studies meeting the inclusion criteria. High CoC was associated with reduced hospitalisation (16 out of 18 studies), emergency room attendances (eight out of eight), mortality rate (six out of seven), disease-related complications (seven out of seven), and healthcare expenses (four out of four) but not with blood pressure (two out of 13), lipid profile (one out of six), body mass index (zero out of three). Six out of 12 studies on diabetic outcomes reported significant improvement in haemoglobin A1c by higher CoC. Variations in the classification of continuity of care and outcome definition were identified, making meta-analyses inappropriate. CASP evaluation rated most studies fair in quality, but found insufficient adjustment on confounders, selection bias and short follow-up period were common limitations of current literatures.

CONCLUSION

There is evidence of a strong association between higher continuity of care and reduced mortality rate, complication risks and health service utilisation among DM and/or HT patients but little to no improvement in various health indicators. Significant methodological heterogeneity in how CoC and patient outcomes are assessed limits the ability for meta-analysis of findings. Further studies comprising sufficient confounding adjustment and standardised definitions are needed to provide stronger evidence of the benefits of CoC on patients with DM and/or HT.

Synergy between the pay-for-performance scheme and better physician-patient relationship might reduce the risk of retinopathy in patients with type 2 diabetes

AIMS/INTRODUCTION

This study investigated whether participation by patients with type 2 diabetes in Taiwan's pay-for-performance (P4P) program and maintaining good continuity of care (COC) with their healthcare provider reduced the likelihood of future complications, such as retinopathy.

MATERIALS AND METHODS

The analysis used longitudinal panel data for newly diagnosed type 2 diabetes from the National Health Insurance claims database in Taiwan. COC was measured annually from 2003 to 2013, and was used to allocate the patients to low, medium and high groups. Cox regression analysis was used with time-dependent (time-varying) covariates in a reduced model (with only P4P or COC), and the full model was adjusted with other covariates.

RESULTS

Despite the same significant effects of treatment at primary care, the Diabetes Complications Severity Index scores were significantly associated with the development of retinopathy. After adjusting for these, the hazard ratios for developing retinopathy among P4P participants in the low, medium and high COC groups were 0.594 (95% confidence interval [CI] 0.398-0.898, P = 0.012), 0.676 (95% CI 0.520-0.867, P = 0.0026) and 0.802 (95% CI 0.603-1.030, P = 0.1062), respectively. Thus, patients with low or median COC who participated in the P4P program had a significantly lower risk of retinopathy than those who did not.

CONCLUSIONS

Diabetes care requires a long-term relationship between patients and their care providers. Besides encouraging patients to participate in P4P programs, health authorities should provide more incentives for providers or patients to regularly survey patients' lipid profiles and glucose levels, and reward the better interpersonal relationship to prevent retinopathy.

Cardiovascular events and mortality in people with type 2 diabetes and multimorbidity: A real-world study of patients followed for up to 19 years

AIM

To quantify the risk of cardiovascular disease (CVD) events, all-cause mortality and cardiovascular mortality in patients diagnosed with type 2 diabetes (T2D) and multimorbidity.

METHODS

This retrospective study used English primary and secondary care data to identify 120 409 adults newly diagnosed with T2D during 2000-2018 with follow-up until death or 31 December 2018. Patients were classified according to the level and type of multimorbidity at T2D diagnosis, and adjusted hazard ratios (aHRs) were calculated for each outcome.

RESULTS

In total, 66 977 (55.6%) patients had T2D only, 37 894 (31.5%) had one co-morbidity, 11 357 (9.4%) had two co-morbidities, 3186 (2.6%) patients had three co-morbidities and 995 (0.8%) patients had four or more co-morbidities. Co-morbidities were associated with increased aHRs for all outcomes. Compared with patients with T2D only, at 19 years after diagnosis of T2D the aHR for four or more co-morbidities was 2.57 (95% CI 2.45-2.69) for a CVD event, 1.73 (1.68-1.78) for all-cause mortality and 2.68 (2.52-2.85) for cardiovascular mortality. Also, 100 183 (83.2%) patients had no CVD co-morbidities, 16 874 (14.0%) patients had one CVD co-morbidity and 3352 (2.8%) patients had two or more co-morbidities. Compared with patients with no CVD co-morbidities, at 19 years after diagnosis of T2D the aHR for two or more CVD co-morbidities was 2.42 (2.35-2.49) for a CVD event, 1.44 (1.42-1.47) for all-cause mortality and 2.44 (2.35-2.54) for cardiovascular mortality.

CONCLUSION

In people with T2D, level of multimorbidity and, in particular, CVD multimorbidity increased the risk of subsequent CVD events, mortality and cardiovascular mortality.

Can Continuity of Care Reduce Hospitalization Among Community-dwelling Older Adult Veterans Living With Dementia?

BACKGROUND

Hospitalization is a difficult experience, especially for patients with dementia. Understanding whether better continuity of care (COC) reduces hospitalizations can indicate interventions that might help curb hospitalizations.

OBJECTIVE

To estimate the causal impact of COC on hospitalizations and different reasons for hospitalization among community-dwelling older veterans with dementia.

RESEARCH DESIGN

Population-based observational study using nationwide Veterans Health Administration data linked to Medicare claims in Fiscal Years (FYs) 2014-2015. To account for unobserved confounders we used an instrumental variable for COC-whether veteran changed residence by more than 10 miles.

SUBJECTS

Community-dwelling veterans with dementia aged 66 and older, enrolled in Traditional Medicare (n=105,528).

MEASURES

Bice-Boxerman Continuity of Care (BBC) index (0-worst to 1-best COC); binary indicators of any hospitalization for all causes, for ambulatory care sensitive conditions (ACSCs) and for reasons grouped by major diagnostic category.

RESULTS

The mean BBC in FY 2014 was 0.32 (SD, 0.23). In FY 2015 43.3% of the cohort veterans were hospitalized. A 0.1 higher BBC resulted in 2.4% (95% confidence interval, 0.5%-4.4%) lower probability of hospitalization for all causes. BBC was not associated with hospitalization for ACSCs. Grouped by major diagnostic category, a 0.1 higher BBC resulted in 3.8% (95% confidence interval, 2.1%-5.4%) lower probability of hospitalization for neuropsychiatric diseases/disorders, with no impact on hospitalizations for circulatory, respiratory, infectious, kidney and urinary, digestive, musculoskeletal, and endocrine-metabolic diseases/disorders.

CONCLUSIONS

Among community-dwelling older veterans with dementia, better COC resulted in less hospitalizations, and this effect was primarily due to less hospitalization for neuropsychiatric diseases/disorders but not hospitalization for ACSCs, or other hospitalization reasons.

Implications of the COVID-19 Pandemic for Cardiovascular Disease and Risk-Factor Management

COVID-19 and our public health responses to the pandemic may have far-reaching implications for cardiovascular (CV) risk, affecting the general population and not only survivors of COVID-19. In this narrative review, we discuss how the pandemic may affect general CV risk for years to come and explore the mitigating potential of telehealth interventions. From a health care perspective, the shift away from in-person office visits may have led many to defer routine risk- factor management and may have had unforeseen effects on continuity of care and adherence. Fear of COVID-19 has led some patients to forego care for acute CV events. Curtailment of routine outpatient laboratory testing has likely delayed intensification of risk-factor–modifying medical therapy, and drug shortages and misinformation may have negative impacts on adherence to antihypertensive, glucose-lowering, and lipid-lowering agents. From a societal perspective, the unprecedented curtailment of social and economic activities has led to loss of income, unemployment, social isolation, decreased physical activity, and increased frequency of depression and anxiety, all of which are known to be associated with worse CV risk-factor control and outcomes. We must embrace and evaluate measures to mitigate these potential harms to avoid an epidemic of CV morbidity and mortality in the coming years that could dwarf the initial health effects of COVID-19.

How does chronic multimorbidity affect daily routines? An experience sampling study of community-dwelling adults in Hong Kong

Limited by conventional data collection methods, it is unclear how community-dwelling multimorbid people's daily routines are affected by their co-occurring illnesses. This study investigated the differences in everyday life schedules between multimorbid and nonmultimorbid people. Three hundred community-dwelling adults, representative of the Hong Kong Chinese population, provided real-time self-reports of daily routines over a 7-day study period. Stratified by baseline multimorbidity status, we implemented generalized linear mixed models (binomial) for each of the four outcomes: meal, chores, conversation, and work/school, with time intervals as independent variable and potential confounders adjusted. The odds of engaging in these activities were compared between multimorbid and nonmultimorbid participants by time intervals. Significant differences were identified. Unlike nonmultimorbid participants, late evening (22:00-24:00) was estimated to be the most frequently observed meal time among multimorbid participants (adjusted odds ratio [AOR] = 8.21, 95% confidence interval [CI] = 2.59-26.01 vs. 14:00-16:00), who also did chores significantly earlier in the morning (AOR = 1.97, 95% CI = 1.09-3.58 in 8:00-10:00 vs. 14:00-16:00). Conversations were significantly less likely among multimorbid participants throughout the day. Last, multimorbid participants seemed to have less typical working/schooling hours. Further studies are warranted to investigate how these disruptions may lead to lower levels of quality of life and poorer mental health.

Continuity of care and health care cost among community-dwelling older adult veterans living with dementia

OBJECTIVES

To estimate the causal impact of continuity of care (COC) on total, institutional, and noninstitutional cost among community-dwelling older veterans with dementia.

DATA SOURCES

Combined Veterans Health Administration (VHA) and Medicare data in Fiscal Years (FYs) 2014-2015.

STUDY DESIGN

FY 2014 COC was measured by the Bice-Boxerman Continuity of Care (BBC) index on a 0-1 scale. FY 2015 total combined VHA and Medicare cost, institutional cost of acute inpatient, emergency department [ED], long-/short-stay nursing home, and noninstitutional long-term care (LTC) cost for medical (like skilled-) and social (like unskilled-) services were assessed controlling for covariates. An instrumental variable for COC (change of residence by more than 10 miles) was used to account for unobserved health confounders.

DATA COLLECTION

Community-dwelling veterans with dementia aged 66 and older, enrolled in Traditional Medicare (N = 102 073).

PRINCIPAL FINDINGS

Mean BBC in FY 2014 was 0.32; mean total cost in FY 2015 was $35 425. A 0.1 higher BBC resulted in (a) $4045 lower total cost; (b) $1597 lower acute inpatient cost, $119 lower ED cost, $4368 lower long-stay nursing home cost; (c) $402 higher noninstitutional medical LTC and $764 higher noninstitutional social LTC cost. BBC had no impact on short-stay nursing home cost.

CONCLUSIONS

COC is an effective approach to reducing total health care cost by supporting noninstitutional care and reducing institutional care.

Attrition from specialised rehabilitation associated with an elevated mortality risk: results from a vital status tracing study in Swiss spinal cord injured patients

INTRODUCTION

Study drop-out and attrition from treating clinics is common among persons with chronic health conditions. However, if attrition is associated with adverse health outcomes, it may bias or mislead inferences for health policy and resource allocation.

METHODS

This retrospective cohort study uses data attained through the Swiss Spinal Cord Injury (SwiSCI) cohort study on persons with spinal cord injury (SCI). Vital status (VS) was ascertained either through clinic medical records (MRs) or through municipalities in a secondary tracing effort. Flexible parametric survival models were used to investigate risk factors for going lost to clinic (LTC) and the association of LTC with subsequent risk of mortality.

RESULTS

1924 individuals were included in the tracing study; for 1608 of these cases, contemporary VS was initially checked in the MRs. VS was ascertained for 704 cases of the 1608 cases initially checked in MRs; of the remaining cases (n=904), nearly 90% were identified in municipalities (n=804). LTC was associated with a nearly fourfold higher risk of mortality (HR=3.62; 95% CI 2.18 to 6.02) among persons with traumatic SCI. Extended driving time (ie, less than 30 min compared with 30 min and longer to reach the nearest specialised rehabilitation facility) was associated with an increased risk of mortality (HR=1.51, 95% CI 1.02 to 2.22) for individuals with non-traumatic SCI.

CONCLUSION

The differential risk of LTC according to sociodemographic and SCI lesion characteristics underscores the importance of accounting for attrition in cohort studies on chronic disease populations requiring long-term care. In addition, given the associated risk of mortality, LTC is an issue of concern to clinicians and policy makers aiming to optimise the long-term survival of community-dwelling individuals with traumatic SCI. Future studies are necessary to verify whether it is possible to improve survival prospects of individuals LTC through more persistent outreach and targeted care.

Associations between continuity of primary and specialty physician care and use of hospital-based care among community-dwelling older adults with complex care needs

Objective

While research suggests that higher continuity of primary and specialty physician care can improve patient outcomes, their effects have rarely been examined and compared concurrently. We investigated associations between continuity of primary and specialty physician care and emergency department visits and hospital admissions among community-dwelling older adults with complex care needs.

Methods

We conducted a retrospective cohort study of home care patients in Ontario, Canada, from October 2014 to September 2016. We measured continuity of primary and specialty physician care over the two years prior to a home care assessment and categorized them into low, medium, and high groups using terciles of the distribution. We used Cox regression models to concurrently test the associations between continuity of primary and specialty care and risk of an emergency department visit and hospital admission within six months of assessment, controlling for potential confounders. We examined interactions between continuity of care and count of chronic conditions, count of physician specialties seen, functional impairment, and cognitive impairment.

Results

Of 178,686 participants, 49% had an emergency department visit during follow-up and 27% had a hospital admission. High vs. low continuity of primary care was associated with a reduced risk of an emergency department visit (HR = 0.90 (0.89–0.92)) as was continuity of specialty care (HR = 0.93 (0.91–0.95)). High vs. low continuity of primary care was associated also with a reduced risk of a hospital admission (HR = 0.94 (0.92–0.96)) as was continuity of specialty care (HR = 0.92 (0.90–0.94)). The effect of continuity of specialty care was moderately stronger among patients who saw four or more physician specialties.

Conclusion

Higher continuity of primary physician and specialty physician care had independent, protective effects of similar magnitude against emergency department use and hospital admissions. Improving continuity of specialty care should be a priority alongside improving continuity of primary care in complex, older adult populations with significant specialist use.

Patient Outcomes Following Interhospital Care Fragmentation: A Systematic Review

INTRODUCTION

Interhospital fragmentation of care occurs when patients are admitted to different, disconnected hospitals. It has been hypothesized that this type of care fragmentation decreases the quality of care received and increases hospital costs and healthcare utilization. This systematic review aims to synthesize the existing literature exploring the association between interhospital fragmentation of care and patient outcomes.

METHODS

MEDLINE, the Cochrane Library, EMBASE, and the Science Citation Index were systematically searched for studies published up to April 30, 2018 reporting the association between interhospital fragmentation of care and patient outcomes. We included peer-reviewed observational studies conducted in adults that reported measures of association between interhospital care fragmentation and one or more of the following patient outcomes: mortality, hospital length of stay, cost, and subsequent hospital readmission.

RESULTS

Seventy-nine full texts were reviewed and 22 met inclusion criteria. Nearly all studies defined fragmentation of care as a readmission to a different hospital than the patient was previously discharged from. The strongest association reported was that between a fragmented readmission and in-hospital or short-term mortality (adjusted odds ratio range 0.95-3.62). Over half of the studies reporting length-of-stay showed longer length of stay in fragmented readmissions. All three studies that investigated healthcare utilization suggested an association between fragmented care and odds of subsequent readmission. The study populations and exposures were too heterogenous to perform a meta-analysis.

DISCUSSION

Our review suggests that fragmented hospital readmissions contribute to increased mortality, longer length-of-stay, and increased risk of readmission to the hospital.

Interruptions In Private Health Insurance And Outcomes In Adults With Type 1 Diabetes: A Longitudinal Study

Type 1 diabetes mellitus, which often originates during childhood, is a lifelong disease that requires intensive daily medical management. Because health care services are critical to patients with this disease, we investigated the frequency of interruptions in private health insurance, and the outcomes associated with them, for working-age adults with type 1 diabetes in the United States in the period 2001-15. We designed a longitudinal study with a nested self-controlled case series, using the Clinformatics Data Mart Database. The study sample consisted of 168,612 adults ages 19-64 with type 1 diabetes who had 2.6 mean years of insurance coverage overall. Of these adults, 24.3 percent experienced an interruption in coverage. For each interruption, there was a 3.6 percent relative increase in glycated hemoglobin. The use of acute care services was fivefold greater after an interruption in health insurance compared to before the interruption and remained elevated when stratified by age, sex, or diabetic complications. An interruption was associated with lower perceived health status and lower satisfaction with life. We conclude that interruptions in private health insurance are common among adults with type 1 diabetes and have serious consequences for their well-being.

Multimorbidity in middle age predicts more subsequent hospital admissions than in older age: A nine-year retrospective cohort study of 121,188 discharged in-patients

BACKGROUND

Previous research has suggested a differential short-term effect of multimorbidity on hospitalization by age, with younger groups affected more. This study compares the nine-year hospitalization pattern by age and multimorbidity status in a retrospective cohort of discharged in-patients, who represent a high-need portion of the population.

METHODS

We examined routine clinical records of all patients aged 45+ years with chronic conditions discharged from public general hospitals in 2005 in Hong Kong. Patterns of annual frequencies of hospital admissions and number of hospitalized days over nine years (2005-2014) were compared by multimorbidity status (1, 2, 3+ conditions) and age group (45-64, 65-74, 75+).

RESULTS

Among 121,188 included patients, 33.9% had 2+ conditions and 12.3% had 3+. Hospitalization patterns varied by age and multimorbidity status. For those having only 1 condition, annual number of admissions was similar by age, but older patients had more hospitalized days (4.40 days per person-year for the 45-64 group versus 10.29 for the 75+ group in the 5th year). For those with 3+ conditions, younger patients had more admissions (4.39 admissions per person-year for the 45-64 group versus 1.87 for the 75+ group in the 5th year) but similar number of hospitalized days with older patients. Interaction analysis showed effect of multimorbidity on hospitalization was stronger in younger groups (P < 0.05).

CONCLUSION

Middle-aged discharged in-patients with multimorbidity are admitted more often than their older counterparts and have similar total hospitalized days per year. Further research is needed to investigate chronic care needs of younger people with multimorbidity.

Associations between multimorbidity, all-cause mortality and glycaemia in people with type 2 diabetes: A systematic review

Introduction

Type 2 diabetes (T2D) is a major health priority worldwide and the majority of people with diabetes live with multimorbidity (MM) (the co-occurrence of ≥2 chronic conditions). The aim of this systematic review was to explore the association between MM and all-cause mortality and glycaemic outcomes in people with T2D.

Methods

The search strategy centred on: T2D, MM, comorbidity, mortality and glycaemia. Databases searched: MEDLINE, EMBASE, CINAHL Complete, The Cochrane Library, and SCOPUS. Restrictions included: English language, quantitative empirical studies. Two reviewers independently carried out: abstract and full text screening, data extraction, and quality appraisal. Disagreements adjudicated by a third reviewer.

Results

Of the 4882 papers identified; 41 met inclusion criteria. The outcome was all-cause mortality in 16 studies, glycaemia in 24 studies and both outcomes in one study. There were 28 longitudinal cohort studies and 13 cross-sectional studies, with the number of participants ranging from 96–892,223. Included studies were conducted in high or upper-middle-income countries. Fifteen of 17 studies showed a statistically significant association between increasing MM and higher mortality. Ten of 14 studies showed no significant associations between MM and HbA1c. Four of 14 studies found higher levels of MM associated with higher HbA1c. Increasing MM was significantly associated with hypoglycaemia in 9/10 studies. There was no significant association between MM and fasting glucose (one study). No studies explored effects on glycaemic variability.

Conclusions

This review demonstrates that MM in T2D is associated with higher mortality and hypoglycaemia, whilst evidence regarding the association with other measures of glycaemic control is mixed. The current single disease focused approach to management of T2D seems inappropriate. Our findings highlight the need for clinical guidelines to support a holistic approach to the complex care needs of those with T2D and MM, accounting for the various conditions that people with T2D may be living with.

Can Claims Data Algorithms Identify the Physician of Record?

BACKGROUND

Claims-based algorithms based on administrative claims data are frequently used to identify an individual's primary care physician (PCP). The validity of these algorithms in the US Medicare population has not been assessed.

OBJECTIVE

To determine the agreement of the PCP identified by claims algorithms with the PCP of record in electronic health record data.

DATA

Electronic health record and Medicare claims data from older adults with diabetes.

SUBJECTS

Medicare fee-for-service beneficiaries with diabetes (N=3658) ages 65 years and older as of January 1, 2008, and medically housed at a large academic health system.

MEASURES

Assignment algorithms based on the plurality and majority of visits and tie breakers determined by either last visit, cost, or time from first to last visit.

RESULTS

The study sample included 15,624 patient-years from 3658 older adults with diabetes. Agreement was higher for algorithms based on primary care visits (range, 78.0% for majority match without a tie breaker to 85.9% for majority match with the longest time from first to last visit) than for claims to all visits (range, 25.4% for majority match without a tie breaker to 63.3% for majority match with the amount billed tie breaker). Percent agreement was lower for nonwhite individuals, those enrolled in Medicaid, individuals experiencing a PCP change, and those with >10 physician visits.

CONCLUSIONS

Researchers may be more likely to identify a patient's PCP when focusing on primary care visits only; however, these algorithms perform less well among vulnerable populations and those experiencing fragmented care.

The association of self-efficacy and hospitalization rates in people with type-2 diabetes: A prospective cohort study

AIMS

Self-efficacy is presumed important in chronic disease management; we assessed the association between self-efficacy and risk of hospitalization in adults with type-2 diabetes.

METHODS

A prospective cohort was assembled between December 2011 to December 2013. Participants completed an extensive survey, including a previously validated 6-item assessment of chronic disease management self-efficacy. The association between self-efficacy (low, medium, high) and all-cause hospitalization within 1 year of the survey was assessed using multivariable logistic regression, after adjustment for sociodemographic characteristics, physical, behavioral and psychosocial factors.

RESULTS

Among the cohort (n = 1915), the average age was 64.5 (SD 10.7) years, 45.3% were women and 199 (10.4%), 459 (24.0%) and 1257 (65.6%) participants reported low, medium and high self-efficacy, respectively. Participants with low self-efficacy were younger, had more comorbidities, and followed less healthy behaviors compared to those with high self-efficacy. In unadjusted analyses, low self-efficacy was associated with increased risk of hospitalization (23.6% vs 9.6%; odds ratio (OR) 2.90: 95% confidence interval (95%CI 1.99, 4.23)) compared to those with high self-efficacy, while no significant association was observed for medium self-efficacy level (OR 1.28: 95%CI 0.91, 1.79). After adjustment, there was no difference in hospitalization risk for participants with low (OR 0.99; 95%CI 0.59, 1.67) or medium (OR 0.67; 95%CI 0.44, 1.01) self-efficacy compared to high self-efficacy.

CONCLUSIONS

Our results suggest that self-efficacy is not independently associated with lower all-cause hospitalization in this population. Focus on additional heath aspects are likely required to improve overall health outcomes in people with type-2 diabetes.

Continuity of care with doctors-a matter of life and death? A systematic review of continuity of care and mortality

OBJECTIVE

Continuity of care is a long-standing feature of healthcare, especially of general practice. It is associated with increased patient satisfaction, increased take-up of health promotion, greater adherence to medical advice and decreased use of hospital services. This review aims to examine whether there is a relationship between the receipt of continuity of doctor care and mortality.

DESIGN

Systematic review without meta-analysis.

DATA SOURCES

Peer-reviewed primary research articles, published in English which reported measured continuity of care received by patients from any kind of doctor, in any setting, in any country, related to measured mortality of those patients.

RESULTS

Of the 726 articles identified in searches, 22 fulfilled the eligibility criteria. The studies were all cohort or cross-sectional and most adjusted for multiple potential confounding factors. These studies came from nine countries with very different cultures and health systems. We found such heterogeneity of continuity and mortality measurement methods and time frames that it was not possible to combine the results of studies. However, 18 (81.8%) high-quality studies reported statistically significant reductions in mortality, with increased continuity of care. 16 of these were with all-cause mortality. Three others showed no association and one demonstrated mixed results. These significant protective effects occurred with both generalist and specialist doctors.

CONCLUSIONS

This first systematic review reveals that increased continuity of care by doctors is associated with lower mortality rates. Although all the evidence is observational, patients across cultural boundaries appear to benefit from continuity of care with both generalist and specialist doctors. Many of these articles called for continuity to be given a higher priority in healthcare planning. Despite substantial, successive, technical advances in medicine, interpersonal factors remain important.

The effect of provider affiliation with a primary care network on emergency department visits and hospital admissions

BACKGROUND

Primary care networks are designed to facilitate access to inter-professional, team-based care. We compared health outcomes associated with primary care networks versus conventional primary care.

METHODS

We obtained data on all adult residents of Alberta who visited a primary care physician during fiscal years 2008 and 2009 and classified them as affiliated with a primary care network or not, based on the physician most involved in their care. The primary outcome was an emergency department visit or nonelective hospital admission for a Patient Medical Home indicator condition (asthma, chronic obstructive pulmonary disease, heart failure, coronary disease, hypertension and diabetes) within 12 months.

RESULTS

Adults receiving care within a primary care network (n = 1 502 916) were older and had higher comorbidity burdens than those receiving conventional primary care (n = 1 109 941). Patients in a primary care network were less likely to visit the emergency department for an indicator condition (1.4% v. 1.7%, mean 0.031 v. 0.035 per patient, adjusted risk ratio [RR] 0.98, 95% confidence interval [CI] 0.96-0.99) or for any cause (25.5% v. 30.5%, mean 0.55 v. 0.72 per patient, adjusted RR 0.93, 95% CI 0.93-0.94), but were more likely to be admitted to hospital for an indicator condition (0.6% v. 0.6%, mean 0.018 v. 0.017 per patient, adjusted RR 1.07, 95% CI 1.03-1.11) or all-cause (9.3% v. 9.1%, mean 0.25 v. 0.23 per patient, adjusted RR 1.08, 95% CI 1.07-1.09). Patients in a primary care network had 169 fewer all-cause emergency department visits and 86 fewer days in hospital (owing to shorter lengths of stay) per 1000 patient-years.

INTERPRETATION

Care within a primary care network was associated with fewer emergency department visits and fewer hospital days.

Use of Direct Oral Anticoagulants in Canadian Primary Care Practice 2010-2015: A Cohort Study From the Canadian Primary Care Sentinel Surveillance Network

BACKGROUND

As questions have been raised about the appropriateness of direct oral anticoagulant (DOAC) dosing among outpatients with atrial fibrillation, we examined this issue in patients being managed by primary care providers.

METHODS AND RESULTS

This was a retrospective cohort new-user study using electronic medical records from 744 Canadian primary care clinicians. Potentially inappropriate DOAC prescribing was defined as prescribing lower or higher doses than those recommended by guidelines for patients with nonvalvular atrial fibrillation. Of the 6658 patients with nonvalvular atrial fibrillation who were prescribed a DOAC (mean age: 74.8; 55% male), 626 (9.4%) had a CHADS2 score of 0, and 168 (2.5%) had a CHADS-VASc score of 0. Of the DOAC prescriptions, 527 (7.7%) were deemed potentially inappropriate: 496 (7.2%) were potentially underdosed, and 31 (0.5%) were prescribed a dose that was higher than recommended. Patients were more likely to be prescribed lower-than-recommended doses if they were female (adjusted odds ratio [aOR]: 1.3 [95% confidence interval (CI), 1.0-1.5]), had multiple comorbidities (aOR: 1.4 [95% CI, 1.1-1.8])-particularly heart failure (aOR: 1.6 [95% CI, 1.2-2.0]) or dementia (aOR: 1.4 [95% CI, 1.1-1.8])-or if they were also taking aspirin (aOR: 1.7 [95% CI, 1.3-2.1]) or nonsteroidal anti-inflammatory drugs (aOR: 1.2 [95% CI, 1.02-1.5]). Potentially inappropriate DOAC dosing was more common in rural practices (aOR: 2.1 [95% CI, 1.7-2.6]) or smaller practices (aOR: 1.9 [95% CI, 1.6-2.4] for practices smaller than median).

CONCLUSIONS

The vast majority of DOAC prescriptions in our cohort of primary care-managed patients appeared to be for appropriate doses, particularly since prescribing a reduced dose of DOAC may be appropriate in frail patients or those taking other medications that predispose to bleeding.

Early Follow-Up After a Heart Failure Exacerbation

Background—

Although early follow-up for heart failure (HF) is recommended, the time window and which physicians should do the follow-up are unclear. We explored whether (1) follow-up within 14 days and (2) physician continuity influence outcomes within 30 days of a HF exacerbation.

Methods and Results—

Retrospective cohort of all adults in Alberta, Canada, with a first discharge from a hospital or an emergency department where HF was the most responsible diagnosis between April 2002 and November 2013, analyzed using Cox proportional hazards models with time-varying covariates. Of 39 249 adults (mean age, 76.1 years), 21 848 (55.7%) received follow-up from a familiar physician, 3938 (10.0%) saw an unfamiliar physician, and 13 463 (34.3%) had no outpatient visits in the first 14 days after a hospitalization or emergency department visit for HF. The risk of death or hospitalization within 30 days was lower in patients who saw a familiar physician (16.9%; adjusted hazard ratio [aHR], 0.94; 95% confidence interval [CI], 0.89–0.99) than in those who saw an unfamiliar physician (20.0%; aHR, 1.05; 95% CI, 0.97–1.15) or those with no outpatient visits (22.0%; aHR, 1.00 [referent]). The composite of death or emergency department visit or hospitalization within 30 days was also less common with familiar physician follow-up (25.2%; aHR, 0.86; 95% CI, 0.82–0.89) compared with unfamiliar physicians (26.9%; aHR, 0.93; 95% CI, 0.87–0.996) or those with no outpatient follow-up within 14 days (47.5%; aHR, 1.00 [referent]).

Conclusions—

Outpatient follow-up within 14 days after HF exacerbation requiring hospitalization or emergency department visit is associated with better outcomes, particularly if the follow-up is with a familiar physician.

Relationship between continuity of care and adverse outcomes varies by number of chronic conditions among older adults with diabetes

Background

Continuity of care is a basic tenant of primary care practice. However, the evidence on the importance of continuity of care for older adults with complex conditions is mixed.

Objective

To assess the relationship between measurement of continuity of care, number of chronic conditions, and health outcomes.

Design

We analyzed data from a cohort of 1,600 US older adults with diabetes and ≥1 other chronic condition in a private Medicare health plan from July 2010 to December 2011. Multivariate regression models were used to examine the association of baseline continuity (the first 6 months) and the composite outcome of any emergency room use or inpatient hospitalization occurring in the following 12-month period.

Results

After adjusting for baseline covariates, high known provider continuity (KPC) was associated with an 84% (adjusted odds ratio 0.16; 95% confidence interval 0.09–0.26) reduction in the risk of the composite outcome. High KPC was significantly associated with a lower risk of the composite outcome among individuals with ≥6 conditions. However, the usual provider of care and continuity of care indices were not significantly related with the composite outcome in the overall sample or in those with ≥6 conditions.

Conclusion

The relationship between continuity of care and adverse outcomes depends on the measure of continuity of care employed. High morbidity patients are more likely to benefit from continuity of care interventions as measured by the KPC, which measures the proportion of a patient’s visits that are with the same providers over time.
