Health services research in the privacy age

A randomized controlled pilot trial of the functional assessment screening tablet to engage patients at the point of care

BACKGROUND

Healthcare providers play an important role in encouraging healthy behaviors and improving health-related quality of life (HRQoL). They are most effective when they partner with informed, engaged patients.

OBJECTIVE

To examine the impact of a new health-information technology intervention (FAST-Feedback) that provides patients with immediate, personalized, guideline-based feedback regarding tobacco use, physical activity, and HRQoL, and encourages patients to initiate discussions regarding these topics with their primary care physician.

DESIGN

A pilot, randomized controlled trial clustered by resident physician, with patients as the unit of analysis.

PARTICIPANTS

Resident physicians and their out-patients in a single academic health center between May and October 2011.

INTERVENTION

Patients received (intervention) or did not receive (control) FAST-Feedback prior to the clinical encounter.

MAIN OUTCOME MEASURES

Primary outcomes were patient reports of initiating any discussions regarding tobacco use, physical activity, and HRQoL. Subgroup analyses examined patient reports of discussions regarding tobacco use, physical activity, and HRQoL, respectively.

KEY RESULTS

Thirty of the 36 eligible resident physicians (83%) agreed to participate; 173 of their 415 eligible patients (42%) expressed interest in the study and 99 (24%) consented to participate. Compared to controls, a higher percentage of intervention patients reported initiating any discussion with their resident physician, although this difference was not statistically significant (40% vs. 27%; p = 0.12). For subgroup analyses regarding specific topics of discussion, patients in the intervention group reported initiating more discussions regarding mental HRQoL than controls (23% vs. 0%; p = 0.02). There was no difference in patient reports of initiating discussions regarding smoking, physical activity or physical HRQoL.

CONCLUSIONS

Providing patients with immediate, personalized, guideline-based feedback prior to the clinical encounter can increase patient-initiated discussions regarding mental HRQoL. Future work should test FAST-Feedback in a larger population and evaluate the impact on tobacco cessation, increased physical activity, and improvements in HRQoL.

Patterns of response to patient-centered decision support through a personal health record

BACKGROUND

Over 140 million people in the United States have at least one chronic medical condition, but they receive fewer than 60% of guideline-recommended services for these conditions. Increasing patients' involvement in their own care may improve the receipt of guideline-recommended services. We evaluated patients' patterns of responses to notifications regarding guideline-recommended services delivered through a personalized health record (PHR).

MATERIALS AND METHODS

We enrolled 584 participants with high cardiovascular disease risk from 73 primary care practices into an active PHR in which they received patient-centered decision support-notifications delivered via a PHR regarding prevention gaps (i.e., unmet preventive healthcare or chronic disease monitoring). Participants with prevention gaps received up to three weekly messages regarding all services due within a 2-month time frame. These three-message cycles could repeat up to every 2 months for a new, or continuing, prevention gap.

RESULTS

Of the 584 participants, 501 (86%) received at least one reminder. Approximately 61% of these participants accessed the PHR or received the care that triggered the message after the first message and 73% after the first two messages. In subsequent three-message cycles, we observed no change in the number of messages required prior to participants accessing the PHR or receiving recommended care (chi-squared = 12.4, p = 0.3). Of the 2,656 prevention gaps these participants had over 1 year, 1,539 (58%) were closed.

CONCLUSIONS

In this low-intensity intervention, participants accessed the PHR and received recommended care. Providing notification through the PHR allows patients to choose when they receive, and take action on, the message. Notifications can be provided to patients through a PHR without alert fatigue and may be an additional tool to help patients achieve better health.

Racial comparisons of diabetes care and intermediate outcomes in a patient-centered medical home

OBJECTIVE To assess racial differences in diabetes processes and intermediate outcomes of care in an internal medicine, patient-centered medical home (PCMH) group practice. RESEARCH DESIGN AND METHODS We conducted a retrospective cohort study of 1,457 adults with diabetes receiving care from 89 medical providers within a PCMH-designated academic practice between 1 July 2009 and 31 July 2010. We used mixed models to assess independent associations between patient race (non-Hispanic white or black) and 1) receipt of processes of care (A1C and LDL testing, foot and retinal examination, and influenza and pneumococcal vaccination) and 2) achievement of intermediate outcomes (LDL <100 mg/dL, blood pressure [BP] <140/90 mmHg, A1C <7.0% [<53 mmol/mol], and A1C >9.0% [>75 mmol/mol]), controlling for sociodemographic factors, health status, treatment intensity, and clinical continuity. RESULTS Compared with non-Hispanic white patients, black patients were younger, were more often single, had lower educational attainment, and were less likely to have commercial insurance. In unadjusted analyses, fewer black patients received a retinal examination and influenza vaccination during the study period or any lifetime pneumococcal vaccination (P < 0.05 [all comparisons]). Fewer black patients achieved an LDL <100 mg/dL, BP <140/90 mmHg, or A1C <7.0% (<53 mmol/mol), while more black patients had an A1C >9.0% (>75 mmol/mol) (P < 0.05 [all comparisons]). In multivariable models, black patients were less likely to receive A1C testing (odds ratio [OR] 0.57 [95% CI 0.34-0.95]) or influenza vaccination (OR 0.75 [95% CI 0.57-0.99]) or to achieve an LDL <100 mg/dL (OR 0.74 [95% CI 0.55-0.99]) or BP <140/90 mmHg (OR 0.64 [95% CI 0.49-0.84]). CONCLUSIONS Racial differences in processes and intermediate outcomes of diabetes care were present within this PCMH-designated practice, controlling for differences in sociodemographic, clinical, and treatment factors.

Role of health information technologies in the Patient-centered Medical Home

A national effort to reform primary care, known as the Patient-Centered Medical Home (PCMH), requires fulfillment of six standards determined by the National Committee for Quality Assurance to (1) enhance access and continuity, (2) identify and manage patient populations, (3) plan and manage care, (4) provide self-care and community support, (5) track and coordinate care, and (6) measure and improve performance. Information technologies play a vital role in the support of most, if not all, of these standards. However, given the newness of the PCMH, little is known on how health information technologies (HITs) have been employed to accomplish these objectives. This article will review the role of HITs, including electronic health records, web-based patient portals, telemedicine, and patient registries, with a focus on diabetes care, and how these technologies have been engaged in the establishment of the PCMH. In addition, we will discuss the benefits and potential risks and barriers to employing these technologies, including privacy and security concerns, as well as describe next steps for future work in this important area.

Surgical patients' and nurses' opinions and expectations about privacy in care

The purpose of this study was to determine the opinions and expectations of patients and nurses about privacy during a hospital admission for surgery. The study explored what enables and maintains privacy from the perspective of Turkish surgical patients and nurses. The study included 102 adult patients having surgery and 47 nurses caring for them. Data were collected via semistructured questionnaire by face-to-face interviews. The results showed that patients were mostly satisfied by the respect shown to their privacy by the nurses but were less confident of the confidentiality of their personal data. It was found that patients have expectations regarding nursing approaches and attitudes about acknowledging and respecting patient autonomy and confidentiality. It is remarkable that while nurses focused on the physical dimension of privacy, patients focused on informational and psychosocial dimensions of privacy, as well as its physical dimension.

Promoting safe prescribing in primary care with a contraceptive vital sign: a cluster-randomized controlled trial

PURPOSE

Routine assessment of women's pregnancy intentions and contraceptive use-a so-called contraceptive vital sign-may help primary care physicians identify patients who need preconception or contraceptive counseling and be of particular benefit when teratogenic medications are prescribed.

METHODS

We conducted a cluster-randomized controlled trial to evaluate the effect of a contraceptive vital sign on primary care documentation of contraceptive use and change in primary care physicians' provision of family planning services. Academic internists in the intervention group (n = 26) were provided with information on their female patients' pregnancy intentions and contraceptive use immediately before visits; internists in the control group (n = 27) received only standard intake information. Data were abstracted from the electronic health record for 5,371 visits by 2,304 women aged 18 to 50 years.

RESULTS

Documentation of contraception increased from baseline, from 23% to 57% in the intervention group, but remained 28% in the control group, a change of +77.4 (95% confidence interval [CI], 70.7 to 84.1) adjusted percentage points in the former vs +3.1 (95% CI, 1.2 to 5.0) in the latter (P <.001). For visits involving a teratogenic prescription, documentation increased from 14% to 48% in the intervention group and decreased from 29% to 26% in the control group, a change of +61.5 (95% CI, 35.8 to 87.1) adjusted percentage points in the former vs -0.3 (95% CI, -4.3 to 3.6) in the latter (P <.001). Provision of new family planning services increased only minimally with this intervention, however. When women with documented nonuse of contraception were prescribed potential teratogens, only 7% were provided family planning services.

CONCLUSIONS

A contraceptive vital sign improves documentation of contraceptive use; however, ongoing efforts are needed to improve provision of preconception and contraceptive services.

Pregnancy and birth history influence women's experience of menopause

OBJECTIVE

The determinants of experiencing menopausal symptoms are complex, representing biological, psychological, and social factors. We report the impact of one such factor, fertility, on the experience of menopausal symptoms. We hypothesize that nulliparous women will have more dissatisfaction with childbearing choices and more negative attitudes toward menopause but will experience fewer menopausal symptoms.

DESIGN

Women aged 40 to 65 years were recruited from a single internal medicine practice to participate in a 5-year longitudinal study of the impact of menopause on health-related quality of life. Women completed questionnaires including the RAND-36, attitudes toward menopause, menopausal symptoms, and fertility and childbearing. Based on self-reported pregnancy and birth history, we categorized women as parous (one or more live births), nulligravida (no pregnancies or births), and nulliparous (one or more pregnancies and no live births). Categorical variables were analyzed using univariable and multivariable ordered logistic and logistic regression. Continuous variables were analyzed using Student's t test and multivariable linear regression techniques.

RESULTS

The 728 participants were, on average, 50.8 years old with 2.4 pregnancies and 1.7 live births. Compared with parous women, nulligravida and nulliparous women were more likely to report being very dissatisfied with childbearing choices (odds ratio [OR] [95% CI]: 3.3 [2.3-4.6] and 4.0 [2.5-6.4], respectively). Nulliparous, but not nulligravida, women expressed more negative attitudes toward menopause compared with parous women (P<0.001). Nulligravida and nulliparous women were half as likely to report hot flashes as parous women (OR [95% CI]: 0.6 [0.4-0.9] and 0.5 [0.3-0.9], respectively). Compared with parous women, nulligravida women were less likely to report vaginal dryness (OR [95% CI]: 0.5 [0.3-0.7]).

CONCLUSIONS

Our study examined the impact of pregnancy and birth history on menopausal symptoms, and the findings support the hypothesis that women who experience infertility may find menopause to be a time of normalcy and experience fewer hot flashes. Both physiologic and psychosocial mechanisms deserve further study.

Patient difficulty using tablet computers to screen in primary care

BACKGROUND

Patient-administered computerized questionnaires represent a novel tool to assist primary care physicians in the delivery of preventive health care.

OBJECTIVE

The aim of this study was to assess patient-reported ease of use with a self-administered tablet computer-based questionnaire in routine clinical care.

DESIGN

All patients seen in a university-based primary care practice were asked to provide routine screening information using a touch-screen tablet computer-based questionnaire. Patients reported difficulty using the tablet computer after completion of their first questionnaire.

PATIENTS

Ten thousand nine hundred ninety-nine patients completed the questionnaire between January 2004 and January 2006.

MEASUREMENTS

We calculated rates of reporting difficulty (no difficulty, some difficulty, or a lot of difficulty) using the tablet computers based on patient age, sex, race, educational attainment, marital status, and number of comorbid medical conditions. We constructed multivariable ordered logistic models to identify predictors of increased self-reported difficulty using the computer.

RESULTS

The majority of patients (84%) reported no difficulty using the tablet computers to complete the questionnaire, with only 3% reporting a lot of difficulty. Significant predictors of reporting more difficulty included increasing age [odds ratio (OR) 1.05, 95% confidence interval (CI) 1.05-1.05)]; Asian race (OR 2.3, 95% CI 1.8-2.9); African American race (OR 1.4, 95% CI 1.2-1.6); less than a high school education (OR 3.0, 95% CI 2.6-3.4); and the presence of comorbid medical conditions (1-2: OR 1.3, 95% CI 1.2-1.5; > or =3: OR 1.7 95% CI 1.5-2.1).

CONCLUSIONS

The majority of primary care patients reported no difficulty using a self-administered tablet computer-based questionnaire. While computerized questionnaires present opportunities to collect routine screening information from patients, attention must be paid to vulnerable groups.
