Deficits in communication and information transfer between hospital-based and primary care physicians: implications for patient safety and continuity of care

Context  Delayed or inaccurate communication between hospital-based and primary care physicians at hospital discharge may negatively affect continuity of care and contribute to adverse events. Objectives  To characterize the prevalence of deficits in communication and information transfer at hospital discharge and to identify interventions to improve this process. Data Sources  MEDLINE (through November 2006), Cochrane Database of Systematic Reviews, and hand search of article bibliographies. Study Selection  Observational studies investigating communication and information transfer at hospital discharge (n = 55) and controlled studies evaluating the efficacy of interventions to improve information transfer (n = 18). Data Extraction  Data from observational studies were extracted on the availability, timeliness, content, and format of discharge communications, as well as primary care physician satisfaction. Results of interventions were summarized by their effect on timeliness, accuracy, completeness, and overall quality of the information transfer. Data Synthesis  Direct communication between hospital physicians and primary care physicians occurred infrequently (3%-20%). The availability of a discharge summary at the first postdischarge visit was low (12%-34%) and remained poor at 4 weeks (51%-77%), affecting the quality of care in approximately 25% of follow-up visits and contributing to primary care physician dissatisfaction. Discharge summaries often lacked important information such as diagnostic test results (missing from 33%-63%), treatment or hospital course (7%-22%), discharge medications (2%-40%), test results pending at discharge (65%), patient or family counseling (90%-92%), and follow-up plans (2%-43%). Several interventions, including computer-generated discharge summaries and using patients as couriers, shortened the delivery time of discharge communications. Use of standardized formats to highlight the most pertinent information improved the perceived quality of documents. Conclusions  Deficits in communication and information transfer at hospital discharge are common and may adversely affect patient care. Interventions such as computer-generated summaries and standardized formats may facilitate more timely transfer of pertinent patient information to primary care physicians and make discharge summaries more consistently available during follow-up care.      

Development and validation of the General Health Numeracy Test (GHNT)

Objective

Because existing numeracy measures may not optimally assess ‘health numeracy’, we developed and validated the General Health Numeracy Test (GHNT).

Methods

An iterative pilot testing process produced 21 GHNT items that were administered to 205 patients along with validated measures of health literacy, objective numeracy, subjective numeracy, and medication understanding and medication adherence. We assessed the GHNT's internal consistency reliability, construct validity, and explored its predictive validity.

Results

On average, participants were 55.0 ± 13.8 years old, 64.9% female, 29.8% non-White, and 51.7% had incomes ≤$39 K with 14.4 ± 2.9 years of education. Psychometric testing produced a 6-item version (GHNT-6). The GHNT-21 and GHNT-6 had acceptable-good internal consistency reliability (KR-20 = 0.87 vs. 0.77, respectively). Both versions were positively associated with income, education, health literacy, objective numeracy, and subjective numeracy (all p < .001). Furthermore, both versions were associated with participants’ understanding of their medications and medication adherence in unadjusted analyses, but only the GHNT-21 was associated with medication understanding in adjusted analyses.

Conclusions

The GHNT-21 and GHNT-6 are reliable and valid tools for assessing health numeracy.

Practice implications

Brief, reliable, and valid assessments of health numeracy can assess a patient's numeracy status, and may ultimately help providers and educators tailor education to patients.     

Low literacy is associated with uncontrolled blood pressure in primary care patients with hypertension and heart disease

Objectives

To evaluate the association between low literacy and uncontrolled blood pressure (BP) and their associations with medication adherence.

Methods

Cross-sectional study of 423 urban, primary care patients with hypertension and coronary disease. The relationship between low literacy (Rapid Estimate of Adult Literacy in Medicine ≤ 44) and uncontrolled BP (≥140/90 mmHg, ≥130/80 mmHg for patients with diabetes) was evaluated by crude and adjusted logistic regression. Relationships with self-reported adherence and refill adherence were explored using adjusted linear and logistic regression.

Results

Overall, 192 (45%) subjects had low literacy and 227 (52.9%) had uncontrolled BP. Adjusting for age, gender, race, employment, education, mental status, and self-reported adherence, low literacy was associated with uncontrolled BP (OR 1.75, 95% CI 1.06–2.87). Lower self-reported adherence was associated with uncontrolled BP; the relationship between refill adherence and uncontrolled BP was not statistically significant.

Conclusion

Low literacy is independently associated with uncontrolled BP.

Practice implications

Awareness of the relationships among patient literacy, BP control, and medication adherence may guide healthcare providers as they communicate with patients.     

Health Literacy and Control in the Medical Encounter: A Mixed-Methods Analysis

BackgroundPhysician-patient communication can be described according to 4 prototypes of control—paternalism, mutuality, consumerism, or default. Patients with inadequate health literacy skills may be less-active participants in their care and more likely to have paternalistic encounters.MethodsTwo independent coders analyzed 31 transcribed outpatient medical visits between physicians and African American patients with diabetes according to the 4 prototypes of control. Differences in communication and the balance of power by level of patients’ health literacy were analyzed by quantitative and qualitative methods.ResultsFourteen patients (45%) had inadequate health literacy, and most of them (N=8, 57%) had paternalistic encounters. Among patients with marginal or adequate health literacy skills, only 4 (23%) had paternalistic visits (p = .06), and encounters marked by mutuality were most common (N = 9, 53%).ConclusionPatients with inadequate health literacy appear more likely to have paternalistic interactions with their physicians.     

Health literacy explains racial disparities in diabetes medication adherence

Although low health literacy and suboptimal medication adherence are more prevalent in racial/ethnic minority groups than Whites, little is known about the relationship between these factors in adults with diabetes, and whether health literacy or numeracy might explain racial/ethnic disparities in diabetes medication adherence. Previous work in HIV suggests health literacy mediates racial differences in adherence to antiretroviral treatment, but no study to date has explored numeracy as a mediator of the relationship between race/ethnicity and medication adherence. This study tested whether health literacy and/or numeracy were related to diabetes medication adherence, and whether either factor explained racial differences in adherence. Using path analytic models, we explored the predicted pathways between racial status, health literacy, diabetes-related numeracy, general numeracy, and adherence to diabetes medications. After adjustment for covariates, African American race was associated with poor medication adherence (r = -0.10, p < .05). Health literacy was associated with adherence (r = .12, p < .02), but diabetes-related numeracy and general numeracy were not related to adherence. Furthermore, health literacy reduced the effect of race on adherence to nonsignificance, such that African American race was no longer directly associated with lower medication adherence (r = -0.09, p = .14). Diabetes medication adherence promotion interventions should address patient health literacy limitations.     

Hospital medicine fellowships: works in progress

The field of hospital medicine continues to grow rapidly, and with this growth has come the realization that residency alone may not provide the full complement of skills required of a successful hospitalist. As a result, several institutions have started hospitalist fellowships, new programs with the specific goal of training clinicians to improve hospital care. These fellowships offer diverse approaches to preparation for a hospitalist career, with opportunities for advanced training in clinical care, teaching, research, and quality improvement. This article provides an overview of the programs, explores the choices for trainees in selecting a fellowship, and the challenges for institutions in developing a new fellowship. Although hospitalist fellowships are still in evolution, they will play an important role in the development of hospital medicine.     

The ARMS-D out performs the SDSCA,but both are reliable,valid, and predict glycemic control

Aims

The Adherence to Refills and Medications Scale (ARMS) has been associated with objective measures of adherence and may address limitations of existing self-report measures of diabetes medication adherence. We modified the ARMS to specify adherence to diabetes medicines (ARMS-D), examined its psychometric properties, and compared its predictive validity with HbA_1C against the most widely used self-report measure of diabetes medication adherence, the Summary of Diabetes Self-Care Activities medications subscale (SDSCA-MS). We also examined measurement differences by age (<65 vs. ≥65 years) and insulin status.

Methods

We administered self-report measures to 314 adult outpatients prescribed medications for type 2 diabetes and collected point-of-care HbA_1C.

Results

One of the 12-item ARMS-D items was identified as less relevant to adherence to diabetes medications and removed. The 11-item ARMS-D had good internal consistency reliability (α = 0.86), maintained its factor structure, and had convergent validity with the SDSCA-MS (rho = −0.52, p < 0.001). Both the ARMS-D (β = 0.16, p < 0.01) and the SDSCA-MS (β = −0.12, p < 0.05) independently predicted HbA_1C after adjusting for covariates, but this association did not hold among participants ≥65 years in subgroup analyses. There were no differences in ARMS-D or SDSCA-MS scores by insulin status, but participants on insulin reported more problems with adherence on two ARMS-D items (i.e., feeling sick and medicine costs).

Conclusions

The ARMS-D is a reliable and valid measure of diabetes medication adherence, and is more predictive of HbA_1C than the SDSCA-MS, but takes more time to administer. The ARMS-D also identifies barriers to adherence, which may be useful in research and clinical practice.
