Control Beliefs and Risk for Death,Stroke and Myocardial Infarction in Middle-aged and Older Adults: An Observational Study

Background

Chronic health conditions account for the largest proportion of illness-related mortality and morbidity as well as most of healthcare spending in the USA. Control beliefs may be important for outcomes in individuals with chronic illness.

Objective

To determine whether control beliefs are associated with the risk for death, incident stroke and incident myocardial infarction (MI), particularly for individuals with diabetes mellitus (DM) and/or hypertension.

Design

Retrospective cohort study.

Participants

A total of 5,662 respondents to the Health and Retirement Study with baseline health, demographic and psychological data in 2006, with no history of previous stroke or MI.

Main Measures

Perceived global control, measured as two dimensions—“constraints” and “mastery”—and health-specific control were self-reported. Event-free survival was measured in years, where “event” was the composite of death, incident stroke and MI. Year of stroke or MI was self-reported; year of death was obtained from respondents’ family.

Key Results

Mean baseline age was 66.2 years; 994 (16.7 %) had DM and 3,023 (53.4 %) hypertension. Overall, 173 (3.1 %) suffered incident strokes, 129 (2.3 %) had incident MI, and 465 (8.2 %) died. There were no significant interactions between control beliefs and baseline DM or hypertension in predicting event-free survival. Elevated adjusted hazard ratios (HRs) were associated with DM (1.33, 95 % CI 1.07–1.67), hypertension (1.31, 95 % CI 1.07–1.61) and perceived constraints in the third (1.55, 95 % CI 1.12–2.15) and fourth quartiles (1.61, 95 % CI 1.14–2.26). Health-specific control scores in the third (HR 0.78, 95 % CI 0.59–1.03) and fourth quartiles (HR 0.70, 95 % CI 0.53–0.92) were protective, but only the latter category had a statistically significant decreased risk. Combined high perceived constraints and low health-specific control had the highest risk (HR 1.93, 95 % CI 1.41–2.64).

Conclusions

Control beliefs were not associated with differential risk for those with DM and/or hypertension, but they predicted significant differences in event-free survival for the general cohort.

Increased Risk of Mortality among Patients Cared for by Physicians with Short Length-of-Stay Tendencies

Background

Since the introduction of the prospective payment system in 1983, U.S. hospitals have been financially incentivized to reduce inpatient length of stay, and average length of stay has shortened dramatically.

Objective

The purpose of this study was to determine whether short length of stay is associated with worse patient outcomes.

Design

We used a quasi-experimental design to compare the outcomes of admissions assigned to physicians with short versus long length-of-stay tendencies. We used each physician’s mean length of stay to define their length of stay tendency. We then compared the outcomes of admissions assigned to physicians with short versus long length-of-stay tendencies in propensity score-matched and adjusted analyses using mixed-effects and conditional logistic regression models.

Patients

The study included all admissions for 10 common diagnoses among patients admitted to the medical teaching service of an urban academic hospital from 7/1/2002 through 6/30/2008.

Main Measure

The primary outcome was 30-day mortality.

Results

We examined 12,341 admissions among 79 physicians. After propensity score matching, admission groups were similar with respect to all demographic and clinical characteristics. Admissions of patients receiving care from short length-of-stay physicians were associated with significantly increased risk of 30-day mortality in adjusted (OR 1.43, 95 % CI: 1.11–1.85), propensity score-matched (OR 1.33, 95 % CI: 1.08–1.63), and matched and adjusted analyses (OR 1.36, 95 % CI: 0.98–1.90).

Conclusions

Policies that incentivize short length of stay may lead to worse patient outcomes. The financial benefits of shortening inpatient length of stay should be weighed against the potential harm to patients.KEY WORDS: Hospital economics, Incentives, Outcomes, Health services     

Hospitalization-Associated Disability in Adults Admitted to a Safety-Net Hospital

Background

Little is known about hospitalization-associated disability (HAD) in older adults who receive care in safety-net hospitals.

Objectives

To describe HAD and to examine its association with age in adults aged 55 and older hospitalized in a safety-net hospital.

Design

Secondary post hoc analysis of a prospective cohort from a discharge intervention trial, the Support from Hospital to Home for Elders.

Setting

Medicine, cardiology, and neurology inpatient services of San Francisco General Hospital, a safety-net hospital.

Participants

A total of 583 participants 55 and older who spoke English, Spanish, or Chinese. We determined the incidence of HAD 30 days post-hospitalization and ORs for HAD by age group.

Measurements

The outcome measure was death or HAD at 30 days after hospital discharge. HAD is defined as a new or additional disability in one or more activities of daily living (ADL) that is present at hospital discharge compared to baseline. Participants’ functional status at baseline (2 weeks prior to admission) and 30 days post-discharge was ascertained by self-report of ADL function.

Results

Many participants (75.3 %) were functionally independent at baseline. By age group, HAD occurred as follows: 27.4 % in ages 55–59, 22.2 % in ages 60–64, 17.4 % in ages 65–69, 30.3 % in ages 70–79, and 61.7 % in ages 80 or older. Compared to the youngest group, only the adjusted OR for HAD in adults over 80 was significant, at 2.45 (95 % CI 1.17, 5.15).

Conclusions

In adults at a safety-net hospital, HAD occurred in similar proportions among adults aged 55–59 and those aged 70–79, and was highest in the oldest adults, aged ≥ 80. In safety-net hospitals, interventions to reduce HAD among patients 70 years and older should consider expanding age criteria to adults as young as 55.KEY WORDS: Hospitalization, Hospitalization-associated disability, Activities of daily living, Frail elderly, Vulnerable populations     

Meta-analysis of randomized controlled trials on the effectiveness of somatostatin analogues for pancreatic surgery: a Cochrane review

Background:

The use of synthetic analogues of somatostatin following pancreatic surgery is controversial. The aim of this meta-analysis is to determine whether prophylactic somatostatin analogues (SAs) should be used routinely in pancreatic surgery.

Methods:

Randomized controlled trials were identified from the Cochrane Library Trials Register, MEDLINE, EMBASE, Science Citation Index Expanded and reference lists. Data were extracted from these trials by two independent reviewers. The risk ratio (RR), mean difference (MD) and standardized mean difference (SMD) were calculated with 95% confidence intervals (95% CIs) based on intention-to-treat or available case analysis.

Results:

Seventeen trials involving 2143 patients were identified. The overall number of patients with postoperative complications was lower in the SA group (RR 0.71, 95% CI 0.62–0.82), but there was no difference between the groups in perioperative mortality (RR 1.04, 95% CI 0.68–1.59), re-operation rate (RR 1.15, 95% CI 0.56–2.36) or hospital stay (MD −1.04 days, 95% CI −2.54 to 0.46). The incidence of pancreatic fistula was lower in the SA group (RR 0.64, 95% CI 0.53–0.78). The proportion of these fistulas that were clinically significant is not clear. Analysis of results of trials that clearly distinguished clinically significant fistulas revealed no difference between the two groups (RR 0.69, 95% CI 0.34–1.41). Subgroup analysis revealed a shorter hospital stay in the SA group than among controls for patients with malignant aetiology (MD −7.57 days, 95% CI −11.29 to −3.84).

Conclusions:

Somatostatin analogues reduce perioperative complications but do not reduce perioperative mortality. However, they do shorten hospital stay in patients undergoing pancreatic surgery for malignancy. Further adequately powered trials of low risk of bias are necessary.     

Underuse and Overuse of Osteoporosis Screening in a Regional Health System: a Retrospective Cohort Study

BACKGROUND

The United States Preventive Services Task Force (USPSTF) recommends screening for osteoporosis with dual-energy x-ray absorptiometry (DXA) for women aged ≥ 65 years and younger women with increased risk. “Choosing Wisely” initiatives advise avoiding DXA screening in women younger than 65 years without osteoporosis risk factors.

OBJECTIVE

We aimed to determine the extent to which DXA screening is used in accordance with USPSTF recommendations within a regional health system.

DESIGN

This was a retrospective longitudinal cohort study within 13 primary care clinics in the Sacramento, CA region.

PATIENTS

The study included 50,995 women aged 40–85 years without prior osteoporosis screening, diagnosis, or treatment attending primary care visits from 2006 to 2012, observed for a mean of 4.4 years.

MAIN MEASURES

We examined incidence of DXA screening. Covariates included age, race/ethnicity, and osteoporosis risk factors (body mass index < 20, glucocorticoid use, secondary osteoporosis, prior high-risk facture, rheumatoid arthritis, alcohol abuse, and current smoking).

KEY RESULTS

Among previously unscreened women for whom the USPSTF recommends screening, 7-year cumulative incidence of DXA screening was 58.8 % among women aged 60–64 years with ≥ 1 risk factor (95 % CI: 51.9–65.8 %), 57.8 % for women aged 65–74 years (95 % CI: 55.6–60.0 %), and 42.7 % for women aged ≥ 75 years (95 % CI: 38.7–46.7 %). Among women for whom the USPSTF does not recommend screening, 7-year cumulative incidence was 45.5 % among women aged 50–59 years (95 % CI 44.1–46.9 %) and 58.6 % among women aged 60–64 years without risk factors (95 % CI 55.9–61.4 %).

CONCLUSIONS

DXA screening was underused in women at increased fracture risk, including women aged ≥ 65 years. Meanwhile, DXA screening was common among women at low fracture risk, such as younger women without osteoporosis risk factors. Interventions may be needed to augment the value of population screening for osteoporosis.KEY WORDS: osteoporosis, screening, dual-energy x-ray absorptiometry, overuse, underuse     

CMS Reimbursement Reform and the Incidence of Hospital-Acquired Pulmonary Embolism or Deep Vein Thrombosis

BACKGROUND

In October 2008, the Centers for Medicare & Medicaid Services (CMS) stopped reimbursing hospitals for the marginal cost of treating certain preventable hospital-acquired conditions.

OBJECTIVE

This study evaluates whether CMS’s refusal to pay for hospital-acquired pulmonary embolism (PE) or deep vein thrombosis (DVT) resulted in a lower incidence of these conditions.

DESIGN

We employ difference-in-differences modeling using 2007–2009 data from the Nationwide Inpatient Sample, an all-payer database of inpatient discharges in the U.S. Discharges between 1 January 2007 and 30 September 2008 were considered “before payment reform;” discharges between 1 October 2008 and 31 December 2009 were considered “after payment reform.” Hierarchical regression models were fit to account for clustering of observations within hospitals.

PARTICIPANTS

The “before payment reform” and “after payment reform” incidences of PE or DVT among 65–69-year-old Medicare recipients were compared with three different control groups of: a) 60–64-year-old non-Medicare patients; b) 65–69-year-old non-Medicare patients; and c) 65–69-year-old privately insured patients. Hospital reimbursements for the control groups were not affected by payment reform.

INTERVENTION

CMS payment reform for hospital-based reimbursement of patients with hip and knee replacement surgeries.

MAIN MEASURES

The outcome was the incidence proportion of hip and knee replacement surgery admissions that developed pulmonary embolism or deep vein thrombosis.

KEY RESULTS

At baseline, pulmonary embolism or deep vein thrombosis were present in 0.81 % of all hip or knee replacement surgeries for Medicare patients aged 65–69 years old. CMS payment reform resulted in a 35 % lower incidence of hospital-acquired pulmonary embolism or deep vein thrombosis in these patients (p = 0.015). Results were robust to sensitivity analyses.

CONCLUSION

CMS’s refusal to pay for hospital-acquired conditions resulted in a lower incidence of hospital-acquired pulmonary embolism or deep vein thrombosis after hip or knee replacement surgery. Payment reform had the desired direction of effect.KEY WORDS: payment reform, pay-for-performance, hospital-acquired conditions, pulmonary embolism, deep vein thrombosis     

Hospital Strategy Uptake and Reductions in Unplanned Readmission Rates for Patients with Heart Failure: A Prospective Study

BACKGROUND

Despite recent reductions in national unplanned readmission rates, we have relatively little understanding of which hospital strategies are most associated with changes in risk-standardized readmission rates (RSRR).

OBJECTIVE

We examined associations between the change in hospital 30-day RSRR for patients with heart failure and the uptake of strategies over 12–18 months in a national sample of hospitals.

DESIGN

We conducted a prospective study of hospitals using a Web-based survey at baseline (November 2010–May 2011, n = 599, 91.0 % response rate) and 12–18 months later (November 2011–October 2012, n = 501, 83.6 % response rate), with RSRR measured at the same time points. The final analytic sample included 478 hospitals.

PARTICIPANTS

The study included hospitals participating in the Hospital-to-Home (H2H) and State Action on Avoidable Rehospitalizations (STAAR) initiatives.

MAIN MEASURES

We examined associations between change in hospital 30-day RSRR for patients with heart failure and the uptake of strategies previously demonstrated to have increased between baseline and follow-up, using unadjusted and adjusted linear regression.

KEY RESULTS

The average number of strategies taken up from baseline to follow-up was 1.6 (SE = 0.06); approximately one-quarter (25.3 %) of hospitals took up at least three new strategies. Hospitals that adopted the strategy of routinely discharging patients with a follow-up appointment already scheduled experienced significant reductions in RSRR (reduction of 0.63 percentage point, p value < 0.05). Hospitals that took up three or more strategies had significantly greater reductions in RSRR compared to hospitals that took up only zero to two strategies (reduction of 1.29 versus 0.57 percentage point, p value < 0.05). Among the 117 hospitals that took up three or more strategies, 93 unique combinations of strategies were used.

CONCLUSIONS

Although most individual strategies were not associated with RSRR reduction, hospitals that took up any three or more strategies showed significantly greater reduction in RSRR compared to hospitals that took up fewer than three strategies.

Effectiveness of seasonal influenza vaccinations against laboratory‐confirmed influenza‐associated infections among Singapore military personnel in 2010–2013

Background

Limited information is available about seasonal influenza vaccine effectiveness (VE) in tropical communities.

Objectives

Virus subtype-specific VE was determined for all military service personnel in the recruit camp and three other non-recruit camp in Singapore''s Armed Forces from 1 June 2009 to 30 June 2012.

Methods

Consenting servicemen underwent nasal washes, which were tested with RT-PCR and subtyped. The test positive case and test negative control design was used to estimate the VE. To estimate the overall effect of the programme on new recruits, we used an ecological time series approach.

Results

A total of 7016 consultations were collected. The crude estimates for the VE of the triavalent vaccine against both influenza A(H1N1)pdm09 and influenza B were 84% (95% CI 78–88%, 79–86%, respectively). Vaccine efficacy against influenza A(H3N2) was markedly lower (VE 33%, 95% CI −4% to 57%). An estimated 70% (RR = 0·30; 95% CI 0·11–0·84), 39% (RR = 0·61;0·25–1·43) and 75% (RR = 0·25; 95% CI 0·11–0·50) reduction in the risk of influenza A(H1N1)pdm09, influenza A(H3N2) and influenza B infections, respectively, in the recruit camp during the post-vaccination period compared with during the pre-vaccination period was observed.

Conclusions

Overall, the blanket influenza vaccine programme in Singapore''s Armed Forces has had a moderate to high degree of protection against influenza A(H1N1)pdm09 and influenza B, but not against influenza A(H3N2). Blanket influenza vaccination is recommended for all military personnel.     

Patient Perceptions of Whom is Most Involved in Their Care with Successive Duty Hour Limits

BACKGROUND

Although direct patient care is necessary for experiential learning during residency, inpatient perceptions of the roles of resident and attending physicians in their care may have changed with residency duty hours.

OBJECTIVE

We aimed to assess if patients’ perceptions of who is most involved in their care changed with residency duty hours.

DESIGN

This was a prospective observational study over 12 years at a single institution.

PARTICIPANTS

Participants were 22,408 inpatients admitted to the general medicine teaching service from 2001 to 2013, who completed a 1-month follow-up phone interview.

MAIN MEASURES

Percentage of inpatients who reported an attending, resident, or intern as most involved in their care by duty hour period (pre-2003, post-2003–pre-2011, post-2011).

KEY RESULTS

With successive duty hour limits, the percentage of patients who reported the attending as most involved in their care increased (pre-2003 20 %, post-2003–pre-2011 29 %, post-2011 37 %, p < 0.001). Simultaneously, fewer patients reported a housestaff physician (resident or intern) as most involved in their care (pre-2003 20 %, post-2003–pre-2011 17 %, post-2011 12 %, p < 0.001). In multinomial regression models controlling for patient age, race, gender and hospitalist as teaching attending, the relative risk ratio of naming the resident versus the attending was higher in the pre-2003 period (1.44, 95 % CI 1.28-1.62, p < 0.001) than the post-2003–pre-2011 (reference group). In contrast, the relative risk ratio for naming the resident versus the attending was lower in the post-2011 period (0.79, 95 % CI 0.68-0.93, p = 0.004) compared to the reference group.

CONCLUSIONS

After successive residency duty hours limits, hospitalized patients were more likely to report the attending physician and less likely to report the resident or intern as most involved in their hospital care. Given the importance of experiential learning to the formation of clinical judgment for independent practice, further study on the implications of these trends for resident education and patient safety is warranted.KEY WORDS: resident duty hours, patient perceptions, hospital care     

Impact of an Intervention to Improve Weekend Hospital Care at an Academic Medical Center: An Observational Study

Background

Hospital care on weekends has been associated with delays in care, reduced quality, and poor clinical outcomes.

Objective

The purpose of this study was to evaluate the impact of a weekend hospital intervention on processes of care and clinical outcomes. The multifaceted intervention included expanded weekend diagnostic services, improved weekend discharge processes, and increased physician and care management services on weekends.

Design and Patients

This was an interrupted time series observational study of adult non-obstetric patients hospitalized at a single academic medical center between January 2011 and January 2014. The study included 18 months prior to and 19 months following the implementation of the intervention. Data were analyzed using segmented regression analysis with adjustment for confounders.

Main Measures

The primary outcome was average length of stay. Secondary outcomes included percent of patients discharged on weekends, 30-day readmission rate, and in-hospital mortality rate.

Key Results

The study included 57,163 hospitalizations. Following implementation of the intervention, average length of stay decreased by 13 % (95 % CI 10–15 %) and continued to decrease by 1 % (95 % CI 1–2 %) per month as compared to the underlying time trend. The proportion of weekend discharges increased by 12 % (95 % CI 2–22 %) at the time of the intervention and continued to increase by 2 % (95 % CI 1–3 %) per month thereafter. The intervention had no impact on readmissions or mortality. During the post-implementation period, the hospital was evacuated and closed for 2 months due to damage from Hurricane Sandy, and a new hospital-wide electronic health record was introduced. The contributions of these events to our findings are not known. We observed a lower inpatient census and found differences in patient characteristics, including higher rates of Medicaid insurance and comorbidities, in the post-Hurricane Sandy period as compared to the pre-Sandy period.

Conclusions

The intervention was associated with a reduction in length of stay and an increase in weekend discharges. Our longitudinal study also illuminated the challenges of evaluating the effectiveness of a large-scale intervention in a real-world hospital setting.KEY WORDS: Health care delivery, Hospital medicine, Variations, Natural disaster     

Sevelamer Versus Calcium-Based Binders for Treatment of Hyperphosphatemia in CKD: A Meta-Analysis of Randomized Controlled Trials

Background and objectives

People with CKD stages 3–5 and on dialysis (5D) have dramatically increased mortality, which has been associated with hyperphosphatemia in many studies. Oral phosphate binders are commonly prescribed to lower serum phosphate. We conducted an updated meta-analysis of the noncalcium–based binder (non-CBB) sevelamer versus CBBs in CKD stages 3–5D.

Design, setting, participants, & measurements

Randomized, controlled trials comparing sevelamer with CBBs were identified through MEDLINE and the Cochrane Central Register of Controlled Trials. Patient-level outcomes included all-cause mortality, cardiovascular events and mortality, hospitalization, and adverse effects. Intermediate outcomes included vascular calcification and bone changes. Biochemical outcomes included serum phosphate, calcium, parathyroid hormone, lipids, and hypercalcemia. We conducted and reported this review according to Cochrane guidelines.

Results

We included 25 studies to March 31, 2015 with 4770 participants (88% on hemodialysis). Patients receiving sevelamer had lower all–cause mortality (risk ratio [RR], 0.54; 95% confidence interval [95% CI], 0.32 to 0.93), no statistically significant difference in cardiovascular mortality (n=2712; RR, 0.33; 95% CI, 0.07 to 1.64), and an increase in combined gastrointestinal events of borderline statistical significance (n=384; RR, 1.42; 95% CI, 0.97 to 2.08). For biochemical outcomes, patients receiving sevelamer had lower total serum cholesterol (mean difference [MD], −20.2 mg/dl; 95% CI, −25.9 to −14.5 mg/dl), LDL-cholesterol (MD, −21.6 mg/dl; 95% CI, −27.9 to −15.4 mg/dl), and calcium (MD, −0.4 mg/dl; 95% CI, −0.6 to −0.2 mg/dl) and a reduced risk of hypercalcemia (RR, 0.30; 95% CI, 0.19 to 0.48). End of treatment intact parathyroid hormone was significantly higher for sevelamer (MD, 32.9 pg/ml; 95% CI, 0.1 to 65.7 pg/ml). Serum phosphate values showed no significant differences.

Conclusions

Patients with CKD stages 3–5D using sevelamer have lower all–cause mortality compared with those using CBBs. Because of a lack of placebo-controlled studies, questions remain regarding phosphate binder benefits for patients with CKD stages 3–5 and not on dialysis.     

The impact of deep vein thrombosis in critically ill patients: a meta-analysis of major clinical outcomes

Background

Critically ill patients appear to be at high risk of developing deep vein thrombosis (DVT) and pulmonary embolism during their stay in the intensive care unit (ICU). However, little is known about the clinical course of venous thromboembolism in the ICU setting. We therefore evaluated, through a systematic review of the literature, the available data on the impact of a diagnosis of DVT on hospital and ICU stay, duration of mechanical ventilation and mortality in critically ill patients. We also tried to determine whether currently adopted prophylactic measures need to be revised and improved in the ICU setting.

Materials and methods

MEDLINE and EMBASE databases were searched up to week 4 of June 2012. Two reviewers selected studies and extracted data. Pooled results are reported as relative risks and weighted mean differences and are presented with 95% confidence intervals (CI).

Results

Seven studies for a total of 1,783 patients were included. A diagnosis of DVT was frequent in these patients with a mean rate of 12.7% (95% CI: 8.7–17.5%). DVT patients had longer ICU and hospital stays compared to those without DVT (7.28 days; 95% CI: 1.4–13.15; and 11.2 days; 95% CI: 3.82–18.63 days, respectively). The duration of mechanical ventilation was significantly increased in DVT patients (weighted mean difference: 4.85 days; 95% CI: 2.07–7.63). DVT patients had a marginally significant increase in the risk of hospital mortality (relative risk 1.31; 95% CI: 0.99–1.74; p=0.06), and a not statistically significant increase in the risk of ICU mortality (RR 1.64; 95% CI: 0.91–2.93; p=0.10).

Conclusions

A diagnosis of DVT upon ICU admission appears to affect clinically important outcomes including duration of ICU and hospital stay and hospital mortality. Larger, prospective studies are warranted.     

Pancreaticogastrostomy is associated with significantly less pancreatic fistula than pancreaticojejunostomy reconstruction after pancreaticoduodenectomy: a meta-analysis of seven randomized controlled trials

Objectives

This study aimed to compare pancreaticojejunostomy (PJ) with pancreaticogastrostomy (PG) after pancreaticoduodenectomy (PD).

Methods

A literature search of PubMed and the Cochrane Central Register of Controlled Trials for studies comparing PJ with PG after PD was conducted. The primary outcome for meta-analysis was pancreatic fistula. Secondary outcomes were morbidity, mortality, biliary fistula, intra-abdominal fluid collection, hospital length of stay (LoS), postoperative haemorrhage and reoperation. Outcome measures were odds ratios (ORs) and mean differences with 95% confidence intervals (CIs).

Results

Seven recent RCTs encompassing 1121 patients (559 PJ and 562 PG cases) were involved in this meta-analysis. Incidences of pancreatic fistula (10.6% versus 18.5%; OR 0.52, 95% CI 0.37–0.74; P = 0.0002), biliary fistula (2.3% versus 5.7%; OR 0.42, 95% CI 0.03–3.15; P = 0.03) and intra-abdominal fluid collection (8.0% versus 14.7%; OR 0.50, 95% CI 0.34–0.74; P = 0.0005) were significantly lower in the PG than the PJ group, as was hospital LoS (weighted mean difference: −1.85, 95% CI −3.23 to −0.47; P = 0.008). Subgroup analysis indicated that severe pancreatic fistula (grades B or C) occurred less frequently in the PG than the PJ group (8.3% versus 20.5%; OR 0.37, 95% CI 0.23–0.59; P < 0.00001). However, there was no significant difference in morbidity (48.9% versus 51.0%; OR 0.90, 95% CI 0.70–1.16; P = 0.41), mortality (3.2% versus 3.5%; OR 0.82, 95% CI 0.43–1.58; P = 0.56), delayed gastric emptying (16.6% versus 14.7%; relative risk: 1.02, 95% CI 0.62–1.68; P = 0.94), postoperative haemorrhage (9.6% versus 11.1%; OR 0.82, 95% CI 0.54–1.24; P = 0.35) or reoperation (9.9% versus 9.8%; OR 0.93, 95% CI 0.60–1.43; P = 0.73).

Conclusions

Pancreaticogastrostomy provides benefits over PJ after PD, including in the incidences of pancreatic fistula, biliary fistula and intra-abdominal fluid collection and in hospital LoS. Therefore, PG is recommended as a safer and more reasonable alternative to PJ reconstruction after PD.     

The 2012 SAGE wait times program: Survey of Access to GastroEnterology in Canada

BACKGROUND:

Periodically surveying wait times for specialist health services in Canada captures current data and enables comparisons with previous surveys to identify changes over time.

METHODS:

During one week in April 2012, Canadian gastroenterologists were asked to complete a questionnaire (online or by fax) recording demographics, reason for referral, and dates of referral and specialist visits for at least 10 consecutive new patients (five consultations and five procedures) who had not been seen previously for the same indication. Wait times were determined for 18 indications and compared with those from similar surveys conducted in 2008 and 2005.

RESULTS:

Data regarding adult patients were provided by 173 gastroenterologists for 1374 consultations, 540 procedures and 293 same-day consultations and procedures. Nationally, the median wait times were 92 days (95% CI 85 days to 100 days) from referral to consultation, 55 days (95% CI 50 days to 61 days) from consultation to procedure and 155 days (95% CI 142 days to 175 days) (total) from referral to procedure. Overall, wait times were longer in 2012 than in 2005 (P<0.05); the wait time to same-day consultation and procedure was shorter in 2012 than in 2008 (78 days versus 101 days; P<0.05), but continued to be longer than in 2005 (P<0.05). The total wait time remained longest for screening colonoscopy, increasing from 201 days in 2008 to 279 days in 2012 (P<0.05).

DISCUSSION:

Wait times for gastroenterology services continue to exceed recommended targets, remain unchanged since 2008 and exceed wait times reported in 2005.     

Occurrence of Distal Colorectal Neoplasia Among Whites and Blacks Following Negative Flexible Sigmoidoscopy: An Analysis of PLCO Trial

BACKGROUND

It is unclear whether the higher rate of colorectal cancer (CRC) among non-Hispanic blacks (blacks) is due to lower rates of CRC screening or greater biologic risk.

OBJECTIVE

We aimed to evaluate whether blacks are more likely than non-Hispanic whites (whites) to develop distal colon neoplasia (adenoma and/or cancer) after negative flexible sigmoidoscopy (FSG).

DESIGN

We analyzed data of participants with negative FSGs at baseline in the Prostate, Lung, Colorectal, and Ovarian (PLCO) cancer screening trial who underwent repeat FSGs 3 or 5 years later. Subjects with polyps or masses were referred to their physicians for diagnostic colonoscopy. We collected and reviewed the records of diagnostic evaluations.

PARTICIPANTS

Our analytic cohort consisted of 21,550 whites and 975 blacks.

MAIN MEASURES

We did a comparison by race (whites vs. blacks) in the findings of polyps or masses at repeat FSG, the follow-up of abnormal test results and the detection of colorectal neoplasia at diagnostic colonoscopy.

KEY RESULTS

At the follow-up FSG examination, 304 blacks (31.2 %) and 4183 whites (19.4 %) had abnormal FSG, [adjusted relative risk (RR) = 1.00; 95 % confidence interval (CI), 0.90–1.10]. However, blacks were less likely to undergo diagnostic colonoscopy (76.6 % vs. 83.1 %; RR = 0.90; 95 % CI, 0.84–0.96). Among all included patients, blacks had similar risk of any distal adenoma (RR = 0.86; 95 % CI, 0.65–1.14) and distal advanced adenoma (RR = 1.01; 95 % CI, 0.60–1.68). Similar results were obtained when we restricted our analysis to compliant subjects who underwent diagnostic colonoscopy (RR = 1.01; 95 % CI, 0.80–1.29) for any distal adenoma and (RR = 1.18; 95 % CI, 0.73–1.92) for distal advanced adenoma.

CONCLUSIONS

We did not find any differences between blacks and whites in the risk of distal colorectal adenoma 3–5 years after negative FSG. However, follow-up evaluations were lower among blacks.KEY WORDS: PLCO, colorectal cancer disparities, adenomatous polyps, flexible sigmoidoscopy, screening     

Usual Primary Care Provider Characteristics of a Patient-Centered Medical Home and Mental Health Service Use

BACKGROUND

The benefits of the patient-centered medical home (PCMH) over and above that of a usual source of medical care have yet to be determined, particularly for adults with mental health disorders.

OBJECTIVE

To examine qualities of a usual provider that align with PCMH goals of access, comprehensiveness, and patient-centered care, and to determine whether PCMH qualities in a usual provider are associated with the use of mental health services (MHS).

DESIGN

Using national data from the Medical Expenditure Panel Survey, we conducted a lagged cross-sectional study of MHS use subsequent to participant reports of psychological distress and usual provider and practice characteristics.

PARTICIPANTS

A total of 2,358 adults, aged 18–64 years, met the criteria for serious psychological distress and reported on their usual provider and practice characteristics.

MAIN MEASURES

We defined “usual provider” as a primary care provider/practice, and “PCMH provider” as a usual provider that delivered accessible, comprehensive, patient-centered care as determined by patient self-reporting. The dependent variable, MHS, included self-reported mental health visits to a primary care provider or mental health specialist, counseling, and psychiatric medication treatment over a period of 1 year.

RESULTS

Participants with a usual provider were significantly more likely than those with no usual provider to have experienced a primary care mental health visit (marginal effect [ME] = 8.5, 95 % CI = 3.2–13.8) and to have received psychiatric medication (ME = 15.5, 95 % CI = 9.4–21.5). Participants with a PCMH were additionally more likely than those with no usual provider to visit a mental health specialist (ME = 7.6, 95 % CI = 0.7–14.4) and receive mental health counseling (ME = 8.5, 95 % CI = 1.5–15.6). Among those who reported having had any type of mental health visit, participants with a PCMH were more likely to have received mental health counseling than those with only a usual provider (ME = 10.0, 95 % CI = 1.0–19.0).

CONCLUSIONS

Access to a usual provider is associated with increased receipt of needed MHS. Patients who have a usual provider with PCMH qualities are more likely to receive mental health counseling.KEY WORDS: patient-centered medical home, primary care, mental health services, Affordable Care Act, race     

General Practitioners’ Judgment of their Elderly Patients’ Cognitive Status

Background

General practitioners (GP) play an important role in detecting cognitive impairment among their patients.

Objectives

To explore factors associated with GPs’ judgment of their elderly patients’ cognitive status.

Design

Cross-sectional data from an observational cohort study (AgeCoDe study); General practice surgeries in six German metropolitan study centers; home visits by interviewers.

Participants

138 GPs, 3,181 patients (80.13 ± 3.61 years, 65.23% female).

Measurements

General practitioner questionnaire for each patient: familiarity with the patient, patient morbidity, judgment of cognitive status. Home visits by trained interviewers: sociodemographic and clinical data, psychometric test performance. Multivariate regression analysis was used to identify independent associations with the GPs’ judgment of “cognitively impaired” vs. “cognitively unimpaired.”

Results

Less familiar patients (adjusted odds ratio [aOR] 2.42, 95% CI 1.35–4.32, for poor vs. very high familiarity), less mobile patients (aOR 1.29, 95% CI 1.13–1.46), patients with impaired hearing (aOR 5.46, 95% CI 2.35–12.67 for serious vs. no problems), and patients with greater comorbidity (aOR 1.15, 95% CI 1.08–1.22) were more likely to be rated as “cognitively impaired” by their GPs.

Conclusions

The associations between GPs’ assessments of cognitive impairment and their familiarity with their patients and patients’ mobility, hearing, and morbidity provide important insights into how GPs make their judgments.KEY WORDS: general practice, cognition, dementia, clinical judgment     

Trends in the use of pre-operative radiation for adenocarcinoma of the pancreas in the United States

Background

The benefit and timing of radiation therapy (RT) for patients undergoing a resection for pancreatic adenocarcinoma remains unclear. This study identifies trends in the use of radiation over a 10-year period and factors associated with the use of pre-operative radiation, in particular.

Methods

The Surveillance, Epidemiology and End Results registry was used to identify patients aged ≥18 years with pancreatic adenocarcinoma who underwent a surgical resection between 2000 and 2010. Logistic regression was used to identify time trends and factors associated with the use of pre-operative radiation.

Results

The overall use of radiation decreased with time among the 8474 patients who met the inclusion criteria. However, the use of pre-operative radiation increased from 1.8% to 3.9% (P ≤ 0.05). Factors significantly associated with receipt of pre-operative radiation were younger age, treatment in more recent years and having an advanced T-stage tumour. The 5-year hazard of death was significantly less for those who received pre-operative radiation versus surgery alone [hazard ratio (HR) 0.64, 95% confidence interval (CI) 0.55–0.74] and for those who received post-operative radiation versus surgery alone (HR 0.69, 95% CI 0.65–0.73).

Discussion

The use of pre-operative radiation significantly increased during the study period. However, the overall use of pre-operative radiation therapy remains low in spite of the potential benefits.     

Hospital Evaluations by Social Media: A Comparative Analysis of Facebook Ratings among Performance Outliers

BACKGROUND

An increasing number of hospitals and health systems utilize social media to allow users to provide feedback and ratings. The correlation between ratings on social media and more conventional hospital quality metrics remains largely unclear, raising concern that healthcare consumers may make decisions on inaccurate or inappropriate information regarding quality.

OBJECTIVES

The purpose of this study was to examine the extent to which hospitals utilize social media and whether user-generated metrics on Facebook^® correlate with a Hospital Compare^® metric, specifically 30-day all cause unplanned hospital readmission rates.

DESIGN AND PARTICIPANTS

This was a retrospective cross-sectional study conducted among all U.S. hospitals performing outside the confidence interval for the national average on 30-day hospital readmission rates as reported on Hospital Compare. Participants were 315 hospitals performing better than U.S. national rate on 30-day readmissions and 364 hospitals performing worse than the U.S. national rate.

MAIN MEASURES

The study analyzed ratings of hospitals on Facebook’s five-star rating scale, 30-day readmission rates, and hospital characteristics including beds, teaching status, urban vs. rural location, and ownership type.

KEY RESULTS

Hospitals performing better than the national average on 30-day readmissions were more likely to use Facebook than lower-performing hospitals (93.3 % vs. 83.5 %; p < 0.01). The average rating for hospitals with low readmission rates (4.15 ± 0.31) was higher than that for hospitals with higher readmission rates (4.05 ± 0.41, p < 0.01). Major teaching hospitals were 14.3 times more likely to be in the high readmission rate group. A one-star increase in Facebook rating was associated with increased odds of the hospital belonging to the low readmission rate group by a factor of 5.0 (CI: 2.6–10.3, p <  0.01), when controlling for hospital characteristics and Facebook-related variables.

CONCLUSIONS

Hospitals with lower rates of 30-day hospital-wide unplanned readmissions have higher ratings on Facebook than hospitals with higher readmission rates. These findings add strength to the concept that aggregate measures of patient satisfaction on social media correlate with more traditionally accepted measures of hospital quality.KEY WORDS: Performance measurement, Patient satisfaction, Consumer health informatics
