Canadian adaptation of the Newest Vital Sign©, a health literacy assessment tool.

OBJECTIVE: The Newest Vital Sign© (NVS) was developed in the USA to measure patient health literacy in clinical settings. We adapted the NVS for use in Canada, in English and French, and created a computerized version. Our objective was to evaluate the reliability of the Canadian NVS as a self-administered computerized tool. DESIGN: We used a randomized crossover design with a washout period of 3-4 weeks to compare health literacy scores obtained using the computerized version with scores obtained using the standard interviewer-administered NVS. ANOVA models and McNemar's tests assessed differences in outcomes assessed with each version of the NVS and order effects of the testing. SETTING: Participants were recruited from multicultural catchment areas in Ontario and Nova Scotia. SUBJECTS: English- and French-speaking adults aged 18 years or older. RESULTS: A total of 180 (81 %) of the 222 adults (112 English/110 French) initially recruited completed both the interviewer-NVS and computer-NVS. Scores for those who completed both assessments ranged from 0 to 6 with a mean of 3·63 (sd 2·11) for the computerized NVS and 3·41 (sd 2·21) for the interview-administered NVS. Few (n 18; seven English, eleven French) participants' health literacy assessments differed between the two versions. CONCLUSIONS: Overall, the computerized Canadian NVS performed as well as the interviewer-administered version for assessing health literacy levels of English- and French-speaking participants. This Canadian adaptation of the NVS provides Canadian researchers and public health practitioners with an easily administered health literacy assessment tool that can be used to address the needs of Canadians across health literacy levels and ultimately improve health outcomes.

Factors associated with surgical management in an underinsured, safety net population.

BACKGROUND: Few studies include significant numbers of racial and ethnic minority patients. The current study was performed to examine factors that affect breast cancer operations in an underinsured population. METHODS: We performed a retrospective review of all breast cancer patients from January 2010 to May 2012. Patients with American Joint Committee on Cancer clinical stage 0-IIIA breast cancer underwent evaluation for type of operation: breast conservation, mastectomy alone, and reconstruction after mastectomy. RESULTS: The population included 403 patients with mean age 53 years. Twelve of the 50 patients (24%) diagnosed at stage IIIB presented with synchronous metastatic disease. Of the remaining patients, only 2 presented with metastatic disease (0.6%). The initial operation was 65% breast conservation, 26% mastectomy alone, and 10% reconstruction after mastectomy. Multivariate analysis revealed that Hispanic ethnicity (odds ratio [OR], 0.38; 95% CI, 0.19-0.73; P = .004), presentation with palpable mass (OR, 0.34; 95% CI, 0.13-0.90; P = .03), preoperative chemotherapy (OR, 0.25; 95% CI, 0.10-0.62; P = .003) were associated with a lesser likelihood of mastectomy. Multivariate analysis of factors associated with reconstruction after mastectomy showed that operation with Breast surgical oncologist (OR, 18.4; 95% CI, 2.18-155.14; P < .001) and adequate health literacy (OR, 3.13; 95% CI, 0.95-10.30; P = .06) were associated with reconstruction. CONCLUSION: The majority of safety net patients can undergo breast conservation despite delayed presentation and poor use of screening mammography. Preoperative chemotherapy increased the likelihood of breast conservation. Routine systemic workup in patients with operable breast cancer is not indicated.

Health literacy assessment and patient satisfaction in surgical practice.

BACKGROUND: Individuals with limited health literacy have barriers to patient-physician communication. Problems in communication are known to contribute to malpractice litigation. Concern exists, however, about the feasibility and patient acceptance of a health literacy assessment. This study was performed to determine the feasibility of health literacy assessment in surgical practice and its effect on patient satisfaction. STUDY DESIGN: Every patient seen in a Breast Surgery Clinic during a 2-year period was asked to undergo a health literacy assessment with the Newest Vital Sign (NVS) as part of the routine history and physical examination. During the year before routine NVS assessments and during the 2-year study period, all patients were asked to rate their "overall satisfaction with clinic visit" on a 5-point scale. RESULTS: A total of 2,026 of 2,097 patients (96.6%) seen during the study were eligible for the health literacy assessment. Of those, no patients refused assessment, and only one patient was missed. Therefore, 2,025 of 2,026 eligible patients (99.9%) underwent the assessment. The average time for NVS assessment was 2:02 minutes. Only 19% of patients had adequate health literacy. Patient satisfaction ratings were slightly greater during the first year of the health literacy assessment (3.8 vs 3.7, P = .049) compared with the year prior to health literacy assessment and greater during the second year of health literacy assessment (4.1 vs 3.7, P < .0001). CONCLUSION: Routine health literacy assessment is feasible in surgical practice and results in no decrease in patient satisfaction. In fact, satisfaction was greater during the years when health literacy assessments were performed.

Development and validation of a measure of health literacy in the UK: the newest vital sign.

BACKGROUND: Health literacy (HL) is an important public health issue. Current measures have drawbacks in length and/or acceptability. The US-developed Newest Vital Sign (NVS) health literacy instrument measures both reading comprehension and numeracy skills using a nutrition label, takes 3 minutes to administer, and has proven to be acceptable to research subjects. This study aimed to amend and validate it for the UK population. METHODS: We used a three-stage process; (1) a Delphi study with academic and clinical experts to amend the NVS label to reflect UK nutrition labeling (2) community-based cognitive testing to assess and improve ease of understanding and acceptability of the test (3) validation of the NVS-UK against an accepted standard test of health literacy, the Test of Functional Health Literacy in Adults (TOFHLA) (Pearson's r and the area under the Receiver Operating Characteristic (ROC) curve) and participant educational level. A sample size calculation indicated that 250 participants would be required. Inclusion criteria were age 18-75 years and ability to converse in English. We excluded people working in the health field and those with impaired vision or inability to undertake the interview due to cognitive impairment or inability to converse in English. RESULTS: In the Delphi study, 28 experts reached consensus (3 cycles). Cognitive testing (80 participants) yielded an instrument that needed no further refinement. Validation testing (337 participants) showed high internal consistency (Cronbach's Alpha = 0.74). Validation against the TOFHLA demonstrated a Pearson's r of 0.49 and an area under the ROC curve of 0.81. CONCLUSIONS: The NVS-UK is a valid measure of HL. Its acceptability and ease of application makes it an ideal tool for use in the UK. It has potential uses in public health research including epidemiological surveys and randomized controlled trials, and in enabling practitioners to tailor care to patient need.

Geriatric education for the physicians of tomorrow.

The world's population is aging and there is need for more geriatricians. Current training programs, however, are not producing a sufficient number of geriatricians to meet that need, largely because students and residents lack interest in a career in geriatrics. A variety of reasons have been suggested to explain that lack of interest, and several changes in geriatrics training might increase the number of medical trainees who choose a career in geriatrics. These changes include recruiting medical students who are predisposed to geriatrics, loan forgiveness programs for those who enter careers in geriatrics, increased reimbursement for geriatric care, providing geriatric education to physicians in all specialties throughout their training, and refocusing geriatrics training so it includes the care of healthy vigorous older adults, rather than an exclusive focus on those with debility and chronic or fatal illnesses.

Suitability and readability of consumer medical information accompanying prescription medication samples.

OBJECTIVE: To examine readability and formatting characteristics of consumer medication information (CMI) accompanying prescription medication samples. METHODS: We collected the most commonly used prescription medication samples (n=100) from four out-patient clinics at a large teaching hospital in the Southeastern US. Seventeen percent of samples were not pills/tablets and of such diverse nature (e.g., injections, drops, and creams) that there were not enough in any category to draw conclusions. Therefore, our analyses were limited to 83pill/tablet samples, belonging to 11 drug classes (e.g., cardiovascular, and psychiatric). We noted if CMI was present, and if so we assessed it for how instructions were presented, reading level, text size, format/layout, and comprehensibility. RESULTS: No CMI was present in 39 (46.9%) samples. In 19 (22.9%), CMI was contained in a package insert and in 25 (30.2%) it was printed on the medication package. Average reading difficulty of CMI was at the 10th grade level (range=6-15) using the Fry formula, and text point size was small (mean 9.9+/-2.2 on package inserts and 9.4+/-2.6 when printed on packages). CONCLUSIONS: Almost half of samples did not include any type of CMI. For those that had CMI, it was often written at a reading difficulty level higher than the average reading skills of American adults, and the format of most CMI was not optimal for comprehensibility. It is likely that many patients do not understand the instructions accompanying medication samples they receive from clinicians. PRACTICE IMPLICATIONS: Clinicians should be cognizant of the shortcomings of CMI accompanying medication samples and thereby, distribute them to patients with caution. Manufacturers too should consider revising CMI to comply with low-literacy guidelines.

Measuring adult literacy in health care: performance of the newest vital sign.

OBJECTIVE: To compare performance of the newest vital sign (NVS) with existing literacy measures. METHODS: We administered the NVS and REALM to 129 patients, and NVS and S-TOFHLA to 119 patients all in public clinics. RESULTS: The NVS demonstrated high sensitivity for detecting limited literacy and moderate specificity (area under the receiver operating characteristic [AUROC] curve 0.71-0.73). The NVS was less effective than the S-TOFHLA for predicting health outcomes. CONCLUSION: The NVS is able to identify patients with limited literacy skills, but may misclassify those with adequate literacy according to the REALM and S-TOFHLA. NVS scores were not associated with health outcomes.

Quick assessment of literacy in primary care: the newest vital sign.

PURPOSE: Current health literacy screening instruments for health care settings are either too long for routine use or available only in English. Our objective was to develop a quick and accurate screening test for limited literacy available in English and Spanish. METHODS: We administered candidate items for the new instrument and also the Test of Functional Health Literacy in Adults (TOFHLA) to English-speaking and Spanish-speaking primary care patients. We measured internal consistency with Cronbach's alpha and assessed criterion validity by measuring correlations with TOFHLA scores. Using TOFLHA scores <75 to define limited literacy, we plotted receiver-operating characteristics (ROC) curves and calculated likelihood ratios for cutoff scores on the new instrument. RESULTS: The final instrument, the Newest Vital Sign (NVS), is a nutrition label that is accompanied by 6 questions and requires 3 minutes for administration. It is reliable (Cronbach alpha >0.76 in English and 0.69 in Spanish) and correlates with the TOFHLA. Area under the ROC curve is 0.88 for English and 0.72 for Spanish versions. Patients with more than 4 correct responses are unlikely to have low literacy, whereas fewer than 4 correct answers indicate the possibility of limited literacy. CONCLUSION: NVS is suitable for use as a quick screening test for limited literacy in primary health care settings.

Relationship between health care costs and very low literacy skills in a medically needy and indigent Medicaid population.

OBJECTIVES: Previous research established that low literacy is independently associated with poorer health. Our objective was to determine whether low literacy skill also is associated with higher health care charges. METHODS: We studied persons enrolled in Medicaid because of medical need/indigence by testing literacy skills in English or Spanish and measuring annual health care charges. Statistical analyses determined if, after adjusting for sociodemographic variables, literacy was associated with charges. RESULTS: Mean charges among subjects with very low literacy skills (< or =3rd-grade reading level) were 10,688 dollars/year, but only 2,891 dollars for those with better literacy skills (> or =4th-grade reading level), statistically significant difference (P =.025). This difference persisted after adjustment for potentially confounding sociodemographic variables. CONCLUSIONS: Based on this small study, very limited reading skills seem to be independently associated with higher health care charges among medically needy and medically indigent Medicaid patients.

The talking touchscreen: a new approach to outcomes assessment in low literacy.

PURPOSE: Cancer patients who are deficient in literacy skills are particularly vulnerable to experiencing different outcomes due to disparities in care or barriers to care. Outcomes measurement in low literacy patients may provide new insight into problems previously undetected due to the challenges of completing paper-and-pencil forms. DESCRIPTION OF STUDY: A multimedia program was developed to provide a quality of life assessment platform that would be acceptable to patients with varying literacy skills and computer experience. One item at a time is presented on the computer touchscreen, accompanied by a recorded reading of the question. Various colors, fonts and graphic images are used to enhance visibility, and a small picture icon appears near each text element allowing patients to replay the sound as many times as they wish. Evaluation questions are presented to assess patient burden and preferences. RESULTS: An ethnically diverse group of 126 cancer patients with a range of literacy skills and computer experience reported that the 'talking touchscreen' (TT) was easy to use, and commented on the usefulness of the multimedia approach. CLINICAL IMPLICATIONS: The TT is a practical, user-friendly data acquisition method that provides greater opportunities to measure self-reported outcomes in patients with a range of literacy skills.
