Shifts in office and virtual primary care during the early COVID-19 pandemic in Ontario,Canada

BACKGROUND:Globally, primary care changed dramatically as a result of the coronavirus disease 2019 (COVID-19) pandemic. We aimed to understand the degree to which office and virtual primary care changed, and for which patients and physicians, during the initial months of the pandemic in Ontario, Canada.METHODS:This population-based study compared comprehensive, linked primary care physician billing data from Jan. 1 to July 28, 2020, with the same period in 2019. We identified Ontario residents with at least 1 office or virtual (telephone or video) visit during the study period. We compared trends in total physician visits, office visits and virtual visits before COVID-19 with trends after pandemic-related public health measures changed the delivery of care, according to various patient and physician characteristics. We used interrupted time series analysis to compare trends in the early and later halves of the COVID-19 period.RESULTS:Compared with 2019, total primary care visits between March and July 2020 decreased by 28.0%, from 7.66 to 5.51 per 1000 people/day. The smallest declines were among patients with the highest expected health care use (8.3%), those who could not be attributed to a primary care physician (10.2%), and older adults (19.1%). In contrast, total visits in rural areas increased by 6.4%. Office visits declined by 79.1% and virtual care increased 56-fold, comprising 71.1% of primary care physician visits. The lowest uptake of virtual care was among children (57.6%), rural residents (60.6%) and physicians with panels of ≥ 2500 patients (66.0%).INTERPRETATION:Primary care in Ontario saw large shifts from office to virtual care over the first 4 months of the COVID-19 pandemic. Total visits declined least among those with higher health care needs. The determinants and consequences of these major shifts in care require further study.

Primary care is considered the cornerstone of most health systems worldwide, and in higher-income countries, primary care visits are about 30 times more frequent than hospital admissions.¹ Health systems with greater availability of primary care are associated with increased access to care, reduced health inequities, better outcomes and lower costs.² Despite the centrality of primary care to health care systems, little is known about how it has been affected by coronavirus disease 19 (COVID-19).On Mar. 11, 2020, the World Health Organization declared COVID-19 a global pandemic.³ On Mar. 15, Ontario’s Chief Medical Officer of Health issued a directive to ramp down elective surgeries and other nonemergent health services, and on Mar. 19, health care providers and organizations were directed to stop or substantially reduce all nonessential or elective services until further notice.⁴ The Ontario Ministry of Health and the Ontario Medical Association negotiated the addition of temporary billing codes in the province’s schedule of benefits to facilitate virtual care, effective as of Mar. 14 (Appendix 1, available at www.cmaj.ca/lookup/doi/10.1503/cmaj.202303/tab-related-content). In mid to late May 2020, the province undertook a phased resumption of certain in-person health professional services and surgeries.⁴Initial reports from ongoing COVID-19-related surveys of primary care providers in Canada and the United States showed major disruptions to care, decreased payments, challenges keeping offices functioning, lack of personal protective equipment and widespread uptake of virtual care.^5,6 The degree to which virtual care — such as phone calls, video visits and secure text messages — replaced in-person office visits is not known. It is also not known which patients and physicians were most affected by the challenges to office-based practice or the change to virtual visits. We aimed to understand the degree to which office and virtual primary care changed, and for which patients and physicians, during the initial months of the COVID-19 pandemic in Ontario, Canada.     

The Inability of the Consumer Price Index to Measure “Cost of Quality” of Medical Care,Report of the Bureau of Research and Planning

The Consumer Price Index (CPI) of the Bureau of Labor Statistics is an index which measures the price changes of 300 goods and services. Among these 300 items are several which reflect price changes for selected health care and medical care services. These comprise the medical care index and physician fee index, depending on what services are being measured.The Physician Fee Index is based upon charges for five procedures rendered by physicians: Appendectomy, tonsillectomy, obstetrical delivery, home visits and office visits.Although the CPI takes into account quality changes in the prices for various goods, it is unable to do so for services, particularly physicians'' services.The difficulty in measuring the “cost” of quality of medical care overstates price increases in the physician fee and medical care indexes.     

Twenty Years of Medically-Attended Pediatric Varicella and Herpes Zoster in Ontario,Canada: A Population-Based Study

ObjectiveTo determine if reductions in medically-attended pediatric varicella and herpes zoster occurred in Ontario, Canada, after publicly-funded varicella immunization was implemented in 2004.MethodsFor fiscal years (FY) 1992-2011, we examined data on varicella and herpes zoster physician office visits, emergency department (ED) visits, hospitalizations (including for varicella-associated skin and soft tissue infections [SSTI]), and intensive care unit (ICU) admissions, among those aged <18 years. The pre-vaccine, privately-available, and vaccine program eras were FY1992-1998, FY1999-2003, and FY2004-2011, respectively. We used Poisson regressionand Kruskal-Wallis tests (all at the p<0.05 level of significance), and compared rates using incidence rate ratios (IRRs) and 95% confidence intervals (CIs).ResultsIncidence of varicella office visits declined over the study period from a high of 25.1/1,000 in FY1994 to a low of 3.2/1,000 in FY2011. ED visits and hospitalizations followed similar patterns of decreasing rates later in the study period. IRRs comparing the vaccine program versus pre-vaccine eras were 0.29 (95%CI: 0.26-0.32) for office visits, 0.29 (95%CI: 0.21-0.40) for ED visits, and 0.41 (95%CI: 0.10-1.69) for hospitalizations. Annual declines in varicella office visits were 7.7%, 9.1%, 8.4%, and 8.4% per year among children aged <1 year, 1-4 years, 5-11 years, and ≥12 years, respectively (all p<0.001). Age-specific rates of varicella-associated SSTI declined significantly among children <12 years (p<0.001) and rates of ICU admissions decreased significantly for children <1 year (p = 0.02). (p<0.001) over the study period. For children aged 5-17 years, herpes zoster office visits decreased whereas ED visits increased (both p<0.001) and there was a small, non-significant (p = 0.07), decrease in hospitalizations.ConclusionMedically-attended varicella decreased during the study period, particularly since varicella vaccine was publicly-funded. Results suggest immunization program-related changes in varicella epidemiology, including herd effects, demonstrated by reductions in varicella in program-ineligible age groups. We did not observe a consistent impact on herpes zoster.     

Multi-Institutional Sharing of Electronic Health Record Data to Assess Childhood Obesity

Objective

To evaluate the validity of multi-institutional electronic health record (EHR) data sharing for surveillance and study of childhood obesity.

Methods

We conducted a non-concurrent cohort study of 528,340 children with outpatient visits to six pediatric academic medical centers during 2007–08, with sufficient data in the EHR for body mass index (BMI) assessment. EHR data were compared with data from the 2007–08 National Health and Nutrition Examination Survey (NHANES).

Results

Among children 2–17 years, BMI was evaluable for 1,398,655 visits (56%). The EHR dataset contained over 6,000 BMI measurements per month of age up to 16 years, yielding precise estimates of BMI. In the EHR dataset, 18% of children were obese versus 18% in NHANES, while 35% were obese or overweight versus 34% in NHANES. BMI for an individual was highly reliable over time (intraclass correlation coefficient 0.90 for obese children and 0.97 for all children). Only 14% of visits with measured obesity (BMI ≥95%) had a diagnosis of obesity recorded, and only 20% of children with measured obesity had the diagnosis documented during the study period. Obese children had higher primary care (4.8 versus 4.0 visits, p<0.001) and specialty care (3.7 versus 2.7 visits, p<0.001) utilization than non-obese counterparts, and higher prevalence of diverse co-morbidities. The cohort size in the EHR dataset permitted detection of associations with rare diagnoses. Data sharing did not require investment of extensive institutional resources, yet yielded high data quality.

Conclusions

Multi-institutional EHR data sharing is a promising, feasible, and valid approach for population health surveillance. It provides a valuable complement to more resource-intensive national surveys, particularly for iterative surveillance and quality improvement. Low rates of obesity diagnosis present a significant obstacle to surveillance and quality improvement for care of children with obesity.     

Understanding Low-Acuity Visits to the Pediatric Emergency Department

Background

Canadian pediatric emergency department visits are increasing, with a disproportionate increase in low-acuity visits locally (33% of volume in 2008-09, 41% in 2011-12). We sought to understand: 1) presentation patterns and resource implications; 2) parents’ perceptions and motivations; and 3) alternate health care options considered prior to presenting with low-acuity problems.

Methods

We conducted a prospective cohort study at our tertiary pediatric emergency department serving two provinces to explore differences between patients with and without a primary care provider. During four, 2-week study periods over 1 year, parents of low-acuity visits received an anonymous survey. Presentation times, interventions, diagnoses and dispositions were captured on a data collection form linked to the survey by study number.

Results

Parents completed 2,443 surveys (74.1% response rate), with survey-data collection form pairs available for 2,146 visits. Overall, 89.7% of respondents had a primary care provider; 68% were family physicians. Surprisingly, 40% of visits occurred during weekday office hours and 27.3% occurred within 4 hours of symptom onset; 67.5% of those early presenters were for injuries. Few parents sought care from their primary care provider (25%), health information line (20.7%), or urgent care clinic (18.5%); 36% reported that they believed their child’s problem required the emergency department. Forty-five percent required only a history, physical exam and reassurance; only 11% required an intervention not available in an office setting. Patients without a primary care provider were significantly more likely to present during weekday office hours (p = 0.003), have longer symptom duration (p<0.001), and not know of other options (p = 0.001).

Conclusions

Many parents seek pediatric emergency department care for low-acuity problems despite their child having a primary care provider. Ensuring timely access to these providers may help reduce pediatric emergency department overuse. Educational initiatives should inform parents about low-acuity problems and where appropriate care can/should be accessed.     

Adult Obesity and Office‐based Quality of Care in the United States

Nationally representative data on the quality of care for obese patients in US‐ambulatory care settings are limited. We conducted a cross‐sectional analysis of the 2005 and 2006 National Ambulatory Medical Care Survey (NAMCS). We examined obesity screening, diagnosis, and counseling during adult visits and associations with patient and provider characteristics. We also assessed performance on 15 previously published ambulatory quality indicators for obese vs. normal/overweight patients. Nearly 50% (95% confidence interval (CI): 46–54%) of visits lacked complete height and weight data needed to screen for obesity using BMI. Of visits by patients with clinical obesity (BMI ≥30.0 kg/m²), 70% (66–74%) were not diagnosed and 63% (59–68%) received no counseling for diet, exercise, or weight reduction. The percentage of visits not being screened (48%), diagnosed (66%), or counseled (54%) for obesity was also notably higher than expected even for patients with known obesity comorbidities. Performance (defined as the percentage of applicable visits receiving appropriate care) on the quality indicators was suboptimal overall. In particular, performance was no better than 50% for eight quality indicators, which are all related to the prevention and treatment of obesity comorbidities, e.g., coronary artery disease, hypertension, hyperlipidemia, asthma, and depression. Performance did not differ by weight status for any of the 15 quality indicators; however, poorer performance was consistently associated with lack of height and weight measurements. In conclusion, many opportunities are missed for obesity screening and diagnosis, as well as for the prevention and treatment of obesity comorbidities, in office‐based practices across the United States, regardless of patient and provider characteristics.     

Telehealth for Endocrinology: Experience and Effect on Utilization in the Prepandemic Era

ObjectiveTelehealth (TH) use in endocrinology was limited before the COVID-19 pandemic but will remain a major modality of care postpandemic. Reimbursement policies have been limited historically due to concerns of overutilization of visits and testing. Additionally, there is limited literature on endocrinology care delivered via TH for conditions other than diabetes. We assess real-world TH use for endocrinology in a prepandemic environment with the hypothesis that TH would not increase the utilization of total visits or related ancillary testing services compared with conventional (CVL) face-to-face office visits.MethodsA single-institution retrospective cohort study assessing the prepandemic use of TH in endocrinology, consisting of 75 patients seen via TH and 225 patients seen in CVL visits. For most patients, TH was conducted via a clinic-to-clinic model. Outcomes measured were total endocrine visit frequency and frequency of related laboratory and radiology testing per patient, hemoglobin A1C, microalbumin, low-density lipoprotein, thyroid-stimulating hormone, thyroglobulin, and thyroid ultrasounds.ResultsFor all endocrine visits, TH patients had a median of 0.24 (interquartile range, 0.015-0.36) visits per month. CVL patients had a median of 0.20 visits per month (interquartile range, 0.11-0.37). Total visits per month did not vary significantly between groups (P = .051). Hemoglobin A1C outcomes were equivalent and there was no increase in ancillary laboratory testing for the TH group.ConclusionOur observations demonstrate that, in a prepandemic health care setting, TH visits can provide equivalent care for endocrinology patients, without increasing utilization of total visits or ancillary services.     

Transforming the Endocrine Consult: Asynchronous Provider Consultations

Objective: To analyze the impact of virtual consultations on the spectrum and volume of endocrine consults, access to endocrine care, and downstream healthcare utilization.Methods: A program (eConsults) designed to enable and reimburse asynchronous consultations between primary care physicians (PCPs) and specialists at the University of California, San Francisco, was launched in 2012. All eConsults (n = 158) submitted to endocrinology over the first year were analyzed for clinical focus and use of structured referral templates. PCP compliance with specialist recommendations was measured and stratified by provider type. Impact on endocrine referral volume was calculated using simple linear regression. Changes in wait times to endocrine care were analyzed comparing administrative data from the year of and the year prior to the introduction of eConsults. Downstream endocrine office visits, emergency department visits, and hospitalizations were captured by chart abstraction for all standard endocrine eConsults (n = 113).Results: The proportion of endocrine referrals sent as eConsults (15 to 22%) was significantly higher than the combined average for all other participating specialties (7.4%) (P<.001). Overall, 76.0% of endocrinologist recommendations were fully implemented. There was no induced demand in total volume of referrals to endocrinology, and introduction of eConsults significantly improved access to endocrine care (odds ratio, 3.6; 95% confidence interval, 2.7 to 4.9). Rates of downstream healthcare utilization within 6 months of a completed eConsult were low.Conclusion: Use of virtual consultations in a fee-for-service, academic medical center setting significantly improved access to endocrine care and the quality of referrals. Increasing recognition and reimbursement of nontraditional consultation models will be essential to scaling and disseminating these programs.Abbreviations:CI = confidence intervalEHR = electronic health recordPCP = primary care physicianUCSF = University of California, San Francisco     

Impact of Market Competition on Continuity of Care and Hospital Admissions for Asthmatic Children: A Longitudinal Analysis of Nationwide Health Insurance Data 2009-2013

Background

Ambulatory care-sensitive conditions, including asthma, can be managed with timely and effective outpatient care, thereby reducing the need for hospitalization.

Objective

This study assessed the relationship between market competition, continuity of care (COC), and hospital admissions in asthmatic children according to their health care provider.

Methods

A longitudinal design was employed with a 5-year follow-up period, between 2009 and 2013, under a Korean universal health insurance program. A total of 253 geographical regions were included in the analysis, according to data from the Korean Statistical Office. Data from 9,997 patients, aged ≤ 12 years, were included. We measured the COC over a 5-year period using the Usual Provider Continuity (UPC) index. Random intercept models were calculated to assess the temporal and multilevel relationship between market competition, COC, and hospital admission rate.

Results

Of the 9,997 patients, 243 (2.4%) were admitted to the hospital in 2009. In the multilevel regression analysis, as the Herfindahl–Hirschman Index increased by 1,000 points (denoting decreased competitiveness), UPC scores also increased (ß = 0.001; p < 0.0001). In multilevel logistic regression analysis, the adjusted odds ratio (OR) for hospital admissions for individuals with lower COC scores (≥ 2 ambulatory visits and a UPC index score of < 1) was 3.61 (95% CI: 2.98–4.38) relative to the reference group (≥ 2 ambulatory visits and a UPC index score of 1).

Conclusions

Market competition appears to reduce COC; decreased COC was associated with a higher OR for hospital admissions.     

Observational Study Assessing Demographic,Economic and Clinical Factors Associated with Access and Utilization of Health Care Services of Patients with Multiple Sclerosis under Treatment with Interferon Beta-1b (EXTAVIA)

Multiple sclerosis (MS) results in an extensive use of the health care system, even within the first years of diagnosis. The effectiveness and accessibility of the health care system may affect patients'' quality of life. The aim of the present study was to evaluate the health care resource use of MS patients under interferon beta-1b (EXTAVIA) treatment in Greece, the demographic or clinical factors that may affect this use and also patient satisfaction with the health care system. Structured interviews were conducted for data collection. In total, 204 patients (74.02% females, mean age (SD) 43.58 (11.42) years) were enrolled in the study. Analysis of the reported data revealed that during the previous year patients made extensive use of health services in particular neurologists (71.08% visited neurologists in public hospitals, 66.67% in private offices and 48.53% in insurance institutes) and physiotherapists. However, the majority of the patients (52.45%) chose as their treating doctor private practice neurologists, which may reflect accessibility barriers or low quality health services in the public health system. Patients seemed to be generally satisfied with the received health care, support and information on MS (84.81% were satisfied from the information provided to them). Patients'' health status (as denoted by disease duration, disability status and hospitalization needs) and insurance institute were found to influence their visits to neurologists. Good adherence (up to 70.1%) to the study medication was reported. Patients'' feedback on currently provided health services could direct these services towards the patients'' expectations.     

Effects of preventive home visits to elderly people.

OBJECTIVES--To assess the effect of preventive home visits by public health nurses on the state of health of and use of services by elderly people living at home. DESIGN--Randomised controlled trial. SETTING--General population of elderly people in one of the southern regions of the Netherlands. SUBJECTS--580 subjects aged between 75 and 84 years randomly allocated to intervention (292) or control (288) group. INTERVENTIONS--Four visits a year over three years in intervention group. Control group received no home visits. MAIN OUTCOME MEASURES--Self rated health, functional state, well being, loneliness, aspects of the mental state (depressive complaints, memory disturbances), and mortality. Use of services and costs. RESULTS--Visits had no effect on the health of the subjects. In the group visited no higher scores were seen on health related measures, fewer died (42 (14%) v 50 (17%)), and community care increased slightly. In the control group more were referred to outpatient clinics (166 (66%) v 132 (55%)), and they had a 40% increased risk of admission (incidence rate ratio 1.4; 90% confidence interval 1.2 to 1.6). No differences were found in long term institutional care, and overall expenditure per person in the intervention group exceeded that in the control group by 4%. Additional analyses showed that visits were effective for subjects who initially rated their health as poor. CONCLUSIONS--Preventive home visits are not beneficial for the general population of elderly people living at home but might be effective when restricted to subjects with poor health.     

Predictors of Frequent Emergency Room Visits among a Homeless Population

Background

Homelessness, HIV, and substance use are interwoven problems. Furthermore, homeless individuals are frequent users of emergency services. The main purpose of this study was to identify risk factors for frequent emergency room (ER) visits and to examine the effects of housing status and HIV serostatus on ER utilization. The second purpose was to identify risk factors for frequent ER visits in patients with a history of illicit drug use.

Methods

A retrospective analysis was performed on 412 patients enrolled in a Boston-based health care for the homeless program (HCH). This study population was selected as a 2:1 HIV seronegative versus HIV seropositive match based on age, sex, and housing status. A subgroup analysis was performed on 287 patients with history of illicit drug use. Chart data were analyzed to compare demographics, health characteristics, and health service utilization. Results were stratified by housing status. Logistic models using generalized estimating equations were used to predict frequent ER visits.

Results

In homeless patients, hepatitis C was the only predictor of frequent ER visits (OR 4.49, p<0.01). HIV seropositivity was not predictive of frequent ER visits. In patients with history of illicit drug use, mental health (OR 2.53, 95% CI 1.07–5.95) and hepatitis C (OR 2.85, 95% CI 1.37–5.93) were predictors of frequent ER use. HIV seropositivity did not predict ER use (OR 0.45, 95% CI 0.21 – 0.97).

Conclusions

In a HCH population, hepatitis C predicted frequent ER visits in homeless patients. HIV seropositivity did not predict frequent ER visits, likely because HIV seropositive HCH patients are engaged in care. In patients with history of illicit drug use, hepatitis C and mental health disorders predicted frequent ER visits. Supportive housing for patients with mental health disorders and hepatitis C may help prevent unnecessary ER visits in this population.     

Burden of Illness,Annual Healthcare Utilization,and Costs Associated with Commercially Insured Patients with Cushing Disease in The United States

ObjectiveTo describe the burden of illness, healthcare utilization, and costs associated with Cushing disease (CD), a rare disorder resulting from adrenocorticotropic hormone-secreting pituitary tumors, in commercially insured patients in the U.S.MethodsPatients with CD were identified in 2010 in the IMS Health PharMetrics and Truven Health Analytics MarketScan claims databases. Because there is no diagnosis code for CD, patients were identified with a claim for Cushing syndrome and either benign pituitary adenoma or hypophysectomy. We estimated total sand CD-related utilization and costs using pharmacy and medical claims.ResultsWe identified 685 CD patients (81% female; mean age, 41.7 years; mean Charlson comorbidity index, 1.6; mean number of chronic conditions, 4.2); 30.5% of the patients had diabetes, 22.5% had psychiatric disturbances, 21% had infections, 8.6% had osteoporosis, 8% had cardiovascular disease/stroke, 5.5% had kidney stones, and 0.7% had compression fracture of a vertebra. Patients had a mean of 19.8 office visits per year; 38.4% had inpatient hospitalizations and 34.2% visited the emergency department (ED). Patients had a mean of 3.2 CD-related office visits per year; 26.9% had CD-related hospitalizations, 0.9% had CD-related ED visits, and 36.8% had CD treatments. Mean annual total costs were $34,992 (pharmacy, $3,597; medical costs, $31,395). CD-related costs accounted for $14,310 of total costs (CD treatment costs, $9,353; other CD-related costs, $4,957).ConclusionCD patients have a high burden of illness. Among CD patients in this study, 30.5% had diabetes, 22.5% had psychiatric disturbances, 21% had infections, 8.6% had osteoporosis, 8% had cardiovascular disease/ stroke, and 5.5% had kidney stones. Patients had 19.8 office visits per year, and > 34% of patients were hospitalized. Mean total cost of care was approximately $35,000 per year. (Endocr Pract. 2015;21:77-86)     

Acupuncture for chronic headache in primary care: large,pragmatic, randomised trial

Objective To determine the effects of a policy of “use acupuncture” on headache, health status, days off sick, and use of resources in patients with chronic headache compared with a policy of “avoid acupuncture.”Design Randomised, controlled trial.Setting General practices in England and Wales.Participants 401 patients with chronic headache, predominantly migraine.Interventions Patients were randomly allocated to receive up to 12 acupuncture treatments over three months or to a control intervention offering usual care.Main outcome measures Headache score, SF-36 health status, and use of medication were assessed at baseline, three, and 12 months. Use of resources was assessed every three months.Results Headache score at 12 months, the primary end point, was lower in the acupuncture group (16.2, SD 13.7, n = 161, 34% reduction from baseline) than in controls (22.3, SD 17.0, n = 140, 16% reduction from baseline). The adjusted difference between means is 4.6 (95% confidence interval 2.2 to 7.0; P = 0.0002). This result is robust to sensitivity analysis incorporating imputation for missing data. Patients in the acupuncture group experienced the equivalent of 22 fewer days of headache per year (8 to 38). SF-36 data favoured acupuncture, although differences reached significance only for physical role functioning, energy, and change in health. Compared with controls, patients randomised to acupuncture used 15% less medication (P = 0.02), made 25% fewer visits to general practitioners (P = 0.10), and took 15% fewer days off sick (P = 0.2).Conclusions Acupuncture leads to persisting, clinically relevant benefits for primary care patients with chronic headache, particularly migraine. Expansion of NHS acupuncture services should be considered.     

Advanced Radiology Utilization in a Tertiary Care Emergency Department from 2001 to 2010

Objective

To evaluate the utilization trends of advanced radiology, i.e. computed tomography (CT) and magnetic resonance imaging (MRI), examination in an emergency department (ED) of an academic medical center from 2001 to 2010.

Patients and Methods

We assessed the overall CT and MRI utilization, and the ED patient encounters. Each examination was evaluated according to the patient’s age and anatomically relevant regions.

Results

During the study period, 737,760 patient visited the ED, and 156,287 CT and 35,018 MRI examinations were performed. The number of annual ED patients increased from 63,770 in 2001 to 94,609 in 2010 (P = 0.018). The rate of CT utilization increased from 105.5 per 1000 patient visits in 2001 to 289.2 in 2010 (P<0.001), and the rate of MRI utilization increased from 8.1 per 1000 patient visits in 2001 to 74.6 in 2010 (P<0.001). In all of the patient age groups, the overall CT and MRI utilization increased. The greater the patient age, the more likely the use of advanced radiology [CT: 87.1 per 1000 patients in age <20 vs. 293.9 per 1000 in age>60 (P<0.001); MRI: 5.1 per 1000 patients in age <20 vs. 108.7 per 1000 in age>60 (P<0.001)]. Abdomen-pelvis (40.2%) and the head (35.7%) comprised the majority of CT scans, while the head (86.4%) comprised the majority of MRI examinations. The rates of advanced radiology use increased across all anatomical regions, with the highest increase being in chest CT (5.9 per 1000 to 49.2) and head MRI (7.2 per 1000 to 61.9).

Conclusion

We report a three-fold and nine-fold increase in the use of CT and MRI, respectively, during the study period. Additional studies will be required to understand the causes of this change and to determine the effect of advanced radiology utilization on the patient outcome.     

Elevated Steady State WBC and Platelet Counts Are Associated with Frequent Emergency Room Use in Adults with Sickle Cell Anemia

Introduction

Sickle cell anemia has many sequelae that result in emergency department (ED) use, but a minority of patients with sickle cell disease are frequent utilizers and make up the majority of ED visits. If patients who are likely to be frequent ED can be identified in steady state, they can be treated with disease modifying agents in an attempt to reduce ED use frequency. We sought to identify steady state markers for frequent ED use.

Methods

We identified all patients with SS/Sβ0 seen at our facilities in 2012. Health care utilization over the entire year was calculated and ED visit numbers categorized as either 0–1, 2–5, or 6 or more visits a year. Steady state and acutely active laboratory parameters were collected and analyzed using analysis of variance models and odds ratios.

Results

432 adult sickle cell patients were identified, ages 18–87, 54% female, and 38% had been prescribed hydroxyurea. Of the 432 patients,192 had 0–1 visits in the year, 144 had 2–5 visits in the year, and 96 had >6 visits for a total of 2259 visits. Those who had >6 visits accounted for 1750 (77%) of the total visits for the year. When steady state laboratory markers were examined, each additional 50x109/L platelets was associated with 22% greater risk (p < .001); each 1x109/L of WBC was associated with 11% greater risk (p = .003), and each 1g/dL Hb was associated with 23% lower risk (p = .007) of >6 ED visits/year. We did not observe a relationship between baseline HbF, LDH or reticulocyte count with >6 ED visits.

Conclusion

Patients with elevated white blood cell counts, elevated platelet counts, and low hemoglobin levels exhibited higher risk for frequent ED utilization and could be candidates for early and aggressive therapy with disease modifying agents.     

Telemedicine for Hip Preservation Patients: Access,Ability and Preference

BackgroundRecent events have resulted in rapid rises in the use of telemedicine in orthopaedic surgery, despite limited evidence regarding patient preferences or concerns. The purpose of this study is to determine access to and, ability to use telemedicine technology in an adult hip preservation patient population, as well as determine associations with patient characteristics. Additionally, we seek to understand patients’ perceived benefits, risks and preferences of telemedicine.MethodsWe performed a cross-sectional survey administered on patients scheduled to undergo joint preservation surgery by one of three surgeons at a single academic institution. Both preoperative and postoperative established patients were included and called for a telephone administered survey if a date of surgery was scheduled between October 1, 2019 and March 30, 2020 and were 18 years or older. The survey had seven sections with 45 questions relating to demographics, technology access, videoconferencing capability, confidence using technology, telehealth experiences, perceptions.Results101 patients completed the survey (48% response rate, 101/212). Overall, 99% of participants reported using the internet, 94% reporting owning a device capable of videoconferencing, and 86% of patients had participated in a video call in the past year. When asked for their preferred method for a physician visit: 79% ranked in-person as their first choice and 16% ranked a videoconference visit as their first choice. Perceived benefits of telemedicine visits included reduced travel to appointments (97% agree) and reduced cost of attending appointments (69% agree). However, patients were concerned that they would not establish the same patient-physician connection (51% agree) and would not receive the same level of care (38% agree) through telemedicine visits versus in person visits.ConclusionThe majority of hip preservation patients have access to and are capable of using the technology required for telemedicine visits. However, patients still prefer to have in person visits over concerns that they will not establish the same patient-physician connection and will not receive the same level of care. Telemedicine visits in hip preservation patients may be most attractive to return patients with an established doctor-patient relationship, particularly those with concerns for long distances of travel and associated costs.Level of Evidence: III     

Planificación anticipada de los cuidados y del uso de recursos hospitalarios en pacientes con COVID-19 en un programa de atención integrada para adultos mayores frágiles en residencias

ObjectivesTo estimate the magnitude and importance of a process of stratification and advance care planning and the use of health resources, among patients in an integrated health care program for frail elderls in nursing homes,that were referred to the hospital with COVID-19.Material and methodsProspective cohort study of patients > 64 years old with COVID-19 infection, in a health care program in nursing homes (from 3/15/2020 to 9/15/2020). The identification of patients with palliative needs, the performing and visible registration in electronic health records of the advance care planning and the use of intensive care were assessed.ResultsWe included 374 COVID-19 patients. 88% were women, the median age was 88 years old. The 79% were patients with palliative needs, of which 68% had the advance care planning (P<.001) registered in the electronic health record. Only 1% of patients with palliative needs and severity criteria were admitted to the intensive care unit. Overall mortality was 25%. Of those who died, 74% had severity criteria (P<.001) and 90% had palliative needs (P<.001).ConclusionsCarrying out a care process based on identification of patients with palliative needs and advance care planning and a central and visible registration of advance care planning in health records, could improve the quality and safety of care and optimize the use of intensive care health resources at all times and especially in public health emergencies.     

Cost-Effectiveness of an Intervention to Reduce Emergency Re-Admissions to Hospital among Older Patients

Background

The objective is to estimate the cost-effectiveness of an intervention that reduces hospital re-admission among older people at high risk. A cost-effectiveness model to estimate the costs and health benefits of the intervention was implemented.

Methodology/Principal Findings

The model used data from a randomised controlled trial conducted in an Australian tertiary metropolitan hospital. Participants were acute medical admissions aged >65 years with at least one risk factor for re-admission: multiple comorbidities, impaired functionality, aged >75 years, recent multiple admissions, poor social support, history of depression. The intervention was a comprehensive nursing and physiotherapy assessment and an individually tailored program of exercise strategies and nurse home visits with telephone follow-up; commencing in hospital and continuing following discharge for 24 weeks. The change to cost outcomes, including the costs of implementing the intervention and all subsequent use of health care services, and, the change to health benefits, represented by quality adjusted life years, were estimated for the intervention as compared to existing practice. The mean change to total costs and quality adjusted life years for an average individual over 24 weeks participating in the intervention were: cost savings of $333 (95% Bayesian credible interval $ -1,932∶1,282) and 0.118 extra quality adjusted life years (95% Bayesian credible interval 0.1∶0.136). The mean net-monetary-benefit per individual for the intervention group compared to the usual care condition was $7,907 (95% Bayesian credible interval $5,959∶$9,995) for the 24 week period.

Conclusions/Significance

The estimation model that describes this intervention predicts cost savings and improved health outcomes. A decision to remain with existing practices causes unnecessary costs and reduced health. Decision makers should consider adopting this program for elderly hospitalised patients.
