Introdução: A má adesão à terapia anti-hipertensiva medicamentosa é uma causa frequente de dificuldade de controle da pressão arterial. A prevalência de hipertensão resistente (HR) verdadeira não é conhecida pela dificuldade de estimar de maneira precisa a adesão ao tratamento medicamento anti-hipertensivo prescrito na prática clínica. Objetivos: Comparar os métodos direto e indiretos de avaliação da adesão ao tratamento anti-hipertensivo em pacientes com HR, medir a adesão ao tratamento medicamentoso pelo método direto em pacientes com HR, estimar a prevalência de HR verdadeira e identificar características clínico-demográficas associadas à adesão. Métodos: Foram recrutados pacientes com HR, definida como Pressão Arterial (PA) de consultório não controlada (PA Sistólica > 140 mmHg e/ou PA Diastólica > 90 mmHg), usando três ou mais classes de anti-hipertensivos em doses plenas, sendo um diurético; ou com PA de consultório controlada (PA Sistólica < 140 mmHg e PA Diastólica < 90 mmHg), usando quatro ou mais classes de anti-hipertensivos. O método direto de avaliação da adesão consistiu na análise de amostras de urina contendo os anti-hipertensivos prescritos pela técnica de cromatografia líquida de alta pressão (High Pressure Liquid Chromatography Mass - HPLC). As análises foram feitas em quatro oportunidades diferentes, com intervalo médio de 30 dias entre as coletas. Para comparação, foram realizados concomitantemente cinco métodos indiretos de avaliação da adesão: contagem de comprimidos (CTG CP), questionário de adesão MMAS-8, impressão médica, avaliação do farmacêutico e do próprio paciente. Foram considerados pacientes aderentes pelo método direto aqueles que apresentaram todos os anti-hipertensivos prescritos em pelo menos 3 das 4 amostras de urina coletadas; consumo >= 80% dos comprimidos pela CTG CP; pontuação >= 7 no questionário MMAS-8 e nota >= 4 nas avaliações médica, farmacêutica e do próprio paciente. Para a avaliação da concordância entre os métodos foi utilizado o coeficiente de correlação de Kappa (CCK). Resultados: 50 pacientes com HR foram recrutados: 68% mulheres, com idade média de 55,1 anos (± 8,2 anos), índice de massa corpórea 29 (± 3,3 kg/m2), PA de Consultório 149/86 mmHg (± 26/15 mmHg), PA de 24 horas pela Monitoração Ambulatorial da Pressão Arterial (MAPA) de 127/82 mmHg (± 19/11 mmHg) e número de classes de anti-hipertensivos prescritos por paciente de 4,6 (± 0,7). A frequência de não adesão encontrada pelo método direto foi de 66%. Classificando os pacientes de acordo com a adesão e o controle da PA pela MAPA, 42% foram considerados pseudo-hipertensos resistentes por má adesão e apenas 18% hipertensos resistentes verdadeiros. A concordância entre os métodos avaliados foi baixa de acordo com o CCK, variando de não existente [métodos CTG CP (-0,040), impressão farmacêutica (-0,040) e do paciente (-0,132)] a mínima [questionário MMAS-8 (0,055) e impressão médica (0,126)]. Nenhuma das características clínicodemográficas avaliadas mostrou qualquer associação com a adesão pelo método direto. Conclusão: A prevalência de não adesão é alta em pacientes com HR, sendo esta, provavelmente, a principal causa de resistência ao tratamento antihipertensivo. Os métodos de adesão indiretos avaliados não apresentaram concordância com o método direto, devendo ser questionável sua utilização como ferramenta de medida de adesão na prática clínica / Background: Poor adherence to antihypertensive therapy is a frequent cause of resistant hypertension (RH). The real prevalence of true RH is still unknown due to the difficulty to accurately estimating adherence to the antihypertensive drug in clinical practice. Objective: Compare the direct and indirect methods of assessing adherence to hypertension treatment, measure the adherence to the drug treatment by the direct method in patients with RH, estimate the prevalence of true RH and to identify clinical and demographic characteristics associated with adherence. Methods: Patients with RH were enrolled: office blood pressure (BP) above goal (systolic BP > 140mmHg and/or diastolic BP > 90mmHg), taking three or more antihypertensive drugs of different classes at optimal dose, which one of them should be a diuretic; or office BP below goal (systolic BP < 140mmHg and/or diastolic BP< 90mmHg), taking four or more antihypertensive drugs. Adherence was assessed by direct method of High Pressure Liquid Chromatography (HPLC) analysis for antihypertensive drugs, in 4 different urine samples, in a 30-day interval. For comparison, five indirect methods of adherence assessment were performed simultaneously: pill count, MMAS-8 questionnaire, patient self-report, physician judgement and pharmaceutical judgement. Patient was considered adherent by direct method if every antihypertensive drug was found in 3 urine samples at least; if he consumed 80% of prescribed medication at least; if he reached score >= 7 on the MMAS-8; >= 4 on self-report, physician judgement and pharmaceutical judgement. Kappa correlation coefficient (KCC) was performed to evaluate the agreement between the methods. Results: 50 patients with HR were enrolled: 68% women, mean age 55,1 ± 8,2 years, body mass index 29 ± 3,3 kg/m2, office BP 149/86 ± 26/15 mmHg, mean 24 hs by Ambulatory Blood Pressure Monitoring (ABPM) 127/82 ± 19/11 mmHg and average of antihypertensive druhs prescribed 4,6 ± 0,7 classes. 66% of patients were non-adherent by direct method: 42% classified as pseudoresistant hypertensive patients due to low adherence and only 18% as true resistant hypertensive. Agreement between methods was low according to KCC, ranging from non-existent [pill count (-0,040), pharmaceutical judgement (-0,040) and self-report (-0,132)] to minimum [MMAS-8 questionnaire (0,055) and physician judgement (0,126)]. There is no association between clinical and demographic characteristics and adherence by direct methods. Conclusion: The prevalence of non-adherence is high in patients with RH, which is probably the main cause of resistance to antihypertensive treatment. The indirect adherence methods evaluated did not show agreement with the direct method, and its use as a tool to measure adherence in clinical practice should be questionable

Evidence suggests that the prevalence of certain non-communicable diseases, such as hypertension, is increasing rapidly, and that patients with these diseases are making significant demands on the health services of the nations in sub-Saharan Africa. However, these countries also face other health-related challenges such as communicable diseases and underdevelopmentrelated diseases. Developing countries like South Africa have limited resources, in terms of man power and financial capital, to address the challenges that they are facing. Non-communicable diseases cannot be ignored and since health care providers cannot meet the challenges, it is worthwhile to empower patients to be involved in the management of their conditions. Patient education is a tool that can be used to enable patients to manage their chronic conditions and thereby reduce the morbidity and mortality rates of these conditions. The aim of this study was to investigate the effect of a patient education intervention on participants’ levels of knowledge about hypertension and its therapy, beliefs about medicines and adherence to anti-hypertensive therapy. The intervention consisted of talks and discussions with all the participants as one group and as individuals. There was also written information given to the participants. Their levels of knowledge about hypertension and its therapy were measured using one-on-one interviews and self-administered questionnaires. Beliefs about medicines were measured using the Beliefs about Medicines Questionnaire (BMQ) whilst adherence levels were measured using pill counts, elf-reports and prescription refill records. The participants’ blood pressure readings and body mass indices were also recorded throughout the study. The parameters before and after the educational intervention were compared using statistical analyses. The participants’ levels of knowledge about hypertension and its therapy significantly increased whilst their beliefs about medicines were positively modified after the educational intervention. There were also increases, though not statistically significant, in the participants’ levels of adherence to anti-hypertensive therapy. Unexpectedly, the blood pressure readings and body mass indices increased significantly. The participants gave positive feedback regarding the educational intervention and indicated a desire for similar programmes to be run continuously. They also suggested that such programmes be implemented for other common chronic conditions such as asthma and diabetes. This study proved that patient education programmes can be implemented to modify patients’ levels of knowledge about their conditions and the therapy, beliefs about medicines and adherence to therapy. However, such programmes need to be conducted over a long period of time since changes involving behaviour take a long time.

It is estimated that 6742 South African women are diagnosed with cervical cancer and 3681 women die from the disease every year. In 1993, The Centers for Disease Control declared cervical cancer an Acquired Immunodeficiency Syndrome defining illness. Apart from persistent human papillomavirus infection, HIV infection is the most common co-factor contributing to cervical cancer in South Africa. Studies have noted that in HIV positive women, there has been an occurrence of faster progression to more advanced stages of cervical cancer with high cases of treatment failure and recurrence. There is limited literature available regarding the prognosis of HIV positive women who suffer from cervical cancer. Women who are HIV positive and have cervical cancer have not been evaluated in detail regarding their response and adherence to cervical cancer treatment. Standard treatment protocols for this set of patients have not been defined. The aim of this study was to assess how HIV positive women who have been diagnosed with cervical cancer responded and adhered to cervical cancer therapy which includes: curative radiotherapy; curative chemotherapy; concurrent chemoradiation or palliative radiotherapy. The study also evaluated the effects of the concurrent use of antiretrovirals and cervical cancer treatment. This was done to determine whether invasive cervical cancer in women who were HIV positive could be managed using the same treatment protocols as patients who were HIV negative. A historical cohort design was employed for the study. The study was conducted at the Oncology Department of a tertiary level hospital located in the Eastern Cape Province, South Africa. The total sample consisted of 196 medical records of women diagnosed with cervical cancer between 2005 and 2008. One hundred women were HIV negative, 83 were HIV positive and the HIV status of 13 women could not be determined. The records were audited over a period of two years from the date of diagnosis. The term „complete response‟ referred to patients who had no recurrence of cervical cancer and no evidence of metastases after undergoing treatment. At one month following treatment there was a significant difference in the incidence of complete response between the HIV positive patients and the HIV negative patients (Chi2 = 16.4, d.f. = 1, p = 0.00005, Cramer‟s V = 0.31). The significant difference in response to treatment between the HIV positive patients and the HIV negative patients was maintained at six months after treatment (Chi2 = 15, d.f. = 1, p = 0.00011, Cramer‟s V = 0.34), 12 months after treatment (Chi2 = 20.5, d.f. = 1, p = 0.00001, Cramer‟s V = 0.37), 18 months after treatment (Chi2 = 9.8, d.f. = 1, p = 0.00173, Cramer‟s V = 0.28) and 24 months after treatment (Chi2 = 5.0, d.f. = 1, p = 0.02571, Cramer‟s V = 0.26). At each of these intervals, cases of treatment failure and metastases were significantly higher in the HIV positive women than in the HIV negative women. Although there was no significant difference in the incidence of adherence between the HIV negative women, the HIV positive women who were on HAART and the HIV positive women who were not on HAART, there was a significant difference in the incidence of the various reasons for non adherence between the various groups. These reasons included: missed scheduled appointments (Chi2 = 2.9, d.f. = 2, p = 0.02385, Cramer‟s V = 0.31); low blood count (Chi2 = 4.0, d.f. = 2, p = 0.01327, Cramer‟s V = 0.15); radiotherapy induced skin breakdown (Chi2 = 0.6, d.f. = 2, p = 0.04581, Cramer‟s V = 0.16) and radiotherapy induced diarrhoea (Chi2 = 6.9, d.f. = 2, p = 0.03118, Cramer‟s V = 0.19). According to the 2004 National Antiretroviral Treatment Guidelines, cervical cancer patients would fall into the WHO stage IV category of HIV disease thus all patients with confirmed diagnosis of invasive cervical cancer should be commenced on antiretrovirals as soon as the cancer diagnosis is made regardless of their CD4 count. However, in the current study, 13 percent (n= 83) of the HIV positive women were not on antiretrovirals. The study concluded that HIV positive women had a higher incidence of both treatment failure and metastases to cervical cancer treatment. Standard radiotherapy and concurrent chemoradiation cervical cancer treatment protocols should be still be used in both HIV negative patients and HIV positive patients so as not to compromise tumour control. Furthermore, in accordance with the antiretroviral treatment guidelines, all HIV positive patients with cervical cancer should receive antiretrovirals irrespective of their CD4 count.

Medication adherence is a formidable challenge for the elderly who may have several prescribed medications while dealing with limited incomes and declining health. The primary purpose of this study was to evaluate the Liberty 6000, an automated capsule and tablet dispenser that provides proper medication dosages and is intended to encourage and track medication adherence. Seven focus groups were assembled; these comprised 49 men and women ages 65 to 98 years of Black, Anglo, and Hispanic descent who met the following criteria: living independently or semi-independently, had suffered one or more impairments, and were taking at least three prescription medications. Each focus group session lasted 90 minutes and was tape-recorded and transcribed verbatim, resulting in about 2,600 lines of text. Each question was designed to be open-ended to avoid introducing any bias that might influence the response. The Health Belief Model conceptually guided the study that addressed perceptions of illness susceptibility and severity, barriers, benefits, and cues to action associated with medication adherence. Main benefits of taking medications included avoiding inherited illnesses (or tendencies for illnesses), and reducing illness symptoms. Barriers to taking medications included forgetting, dexterity problems, and high cost. Benefits of the proposed intervention included reminding, caregiver notification, and providing a printed log of medications taken and missed. Barriers associated with the Liberty 6000 included its relatively large size, the difficulties that confronted older adults when loading the device, and its perceived cost. Using an adoption prediction model proposed a way to overcome barriers and encourage acceptance as well as a strategy to maintain acceptance over time. The model also can be used to evaluate a wide variety of medical devices for elderly people. This study identified the advantages and disadvantages of the Liberty 6000. Findings also suggest areas for further investigation by the nursing community and healthcare policy makers in finding solutions to the myriad problems faced by older people in medication adherence.

Bakgrund: Fysisk aktivitet har flera positiva effekter på hälsan. Fysisk aktivitet på recept är en behandlingsmetod mot olika ohälsotillstånd, samt i preventivt syfte. Fysisk aktivitet på recept kan förskrivas av legitimerad vårdpersonal, exempelvis sjuksköterskor.  Syfte: Att beskriva patienters upplevelser av följsamhet till fysisk aktivitet på recept. Metod: Kvalitativ litteraturöversikt med induktiv ansats där tio vetenskapliga artiklar sammanställdes efter analys av materialet enligt Fribergs femstegsanalys.  Resultat: Tre kategorier formades: individuella påverkansfaktorer, sociala påverkansfaktorer och yttre påverkansfaktorer. Individuella påverkansfaktorer berörde exempelvis symtom och tidigare erfarenheter. Sociala faktorer var till exempel stöd från familj och närstående samt vårdpersonal. Yttre påverkansfaktorer handlade bland annat om tid och ekonomi. Slutsats: Både yttre och inre faktorer påverkade följsamheten till receptet. Orsakerna till följsamhet/icke följsamhet var ofta multifaktoriella och komplexa. Vårdpersonalen som förskriver receptet behöver vara lyhörda för patientens behov och förutsättningar. Som förskrivande vårdpersonal är det även viktigt att erbjuda stöd och uppföljningar. / Background: Physical activity (PA) has several beneficial effects on health. Physical activity on prescription (PAP) is a non-medical treatment method and is also used to prevent future illness. Health care practioners with a legitimation – e.g. nurses - can prescribe PAP. Aim: To describe patients experiences of compliance to physical activity on prescription.  Method: A qualitative literature review with inductive approach. Ten articles with qualitative design were analyzed and compiled through Friberg’s analyze in five steps.  Results: The result was organized in three main categories: individual factors, social influential factors and external factors. Individual factors was for example symptoms and previous experience. Social factors was for example support from family, friends and healthcare staff. External factors was for example time and economy. Conclusion: Both external and internal factors had impact on the participants adherence to PAP. The reasons explained by the participants were multifactorial and complex. Health care professionals who prescribe physical activity need to be responsive to the patients` needs and prerequisites. It is also important to offer support and follow-ups.

Today over 1.1 million people are living with HIV/AIDS in the United States; over the last 4 decades mortality rates have decreased largely made in part because of advancement in awareness and treatment options. Treatment adherence has long been considered a vital component in decreasing HIV/AIDS related mortality and has proven to reduce the risk of transmission. However not all patients take their medicine as prescribed. This research study, sponsored by The North Central Texas HIV Planning Council explored how Patient and Provider communication impacted treatment adherence. By utilizing a mixed-methods approach survey data and semi-structured interviews were used to collect insights from both Patients and Providers. Data gleaned through the interview process provided a perspective that could not be captured by using quantitative methods alone. The results from this research yielded multiple themes related to patient and provider communication with recommendations as to how The North Central Texas HIV Planning Council could address treatment adherence, such as Providers focus on Patients perceived severity based on their understanding of disease and illness; that side-effects remain a concern for patients and should not be dismissed; and finally that the word AIDS is perceived to be more stigmatized and as such organizations providing HIV/AIDS related services should explore alternative names where the word AIDS in not included.

Since the Institute of Medicine highlighted the devastating impact of medical errors in their seminal report, “To Err is Human” (2000), efforts have been underway to improve patient safety. A portion of medical errors are due to medication errors, and a large portion of these can be attributed to inadequate laboratory monitoring. In this thesis, I attempt to address this small but important corner of this patient safety endeavor. Why are patients not getting their laboratory monitoring tests? Do they fail to complete them or do doctors not order the tests in the first place? Which prescribers and which patients are least likely to do what is needed for testing to happen and what interventions would be most promising? To address these questions, I conducted a systematic review of existing interventions. I then proceeded with three aims: 1) To identify reasons that patients give for missing monitoring tests; 2) To identify patient and provider factors associated with monitoring test ordering; and 3) To identify patient and provider factors associated with completion of ordered testing. To achieve these aims, I worked with patients and data at the Fallon Clinic. For aim 1, I conducted a qualitative analysis of their reasons for missing tests as well as reporting completion and ordering rates. For aims 2 and 3, I used electronic medical record data and conducted a regression with patient and provider characteristics as covariates to identify factors contributing to test ordering and completion. Interviews revealed that patients had few barriers to completion, with forgetting being the most common reason for missing a test. The quantitative studies showed that: older patients with more interactions with the health care system were more likely to have tests ordered and were more likely to complete them; providers who more frequently prescribe a drug were more likely to order testing for it; and drug-test combinations that were particularly dangerous, indicated by a black box warning, were more likely to have appropriate ordering, though for these combinations, primary care providers were less likely to order tests appropriately, and patients were less likely to complete tests. Taken together, my work can inform future interventions in laboratory monitoring and patient safety.

Little is known about what variables affect self-management practices of adolescents with T1D. Few studies have examined differences in self-management behaviors by stage of adolescence. Similarly, no studies have examined all of the attributes of self-management, including Collaboration with Parents and Goals. In order to fill the gaps in the literature, a secondary data analysis with a descriptive correlation design was conducted to describe T1D self-management behaviors (Collaboration with Parents, Diabetes Care Activities, Diabetes Problem Solving, Diabetes Communication and Goals) during early, middle and late stages of adolescence. This study also examined whether the roles of covariates (regimen, duration of illness (DOI), gender) in self-management behaviors vary by stage of adolescence. Data from 504 subjects aged 13 – 21 years were analyzed and the age variable was transformed into three adolescent stages early (13-14) (n=163), middle (15-16) (n=159) and late (17-21) (n=182). The findings revealed significant differences between adolescent stages on Collaboration with Parents and the Diabetes Problem Solving subscale. The covariate analysis showed no significant effect modification for the covariates and stage on any of the subscales so the results did not differ from the ANOVA model. Covariate analysis showed significant associations between regimen and Collaboration with Parents, Diabetes Care Activities and Diabetes Problem Solving. DOI showed significant associations only with Diabetes Problem solving and gender had significant associations with Diabetes Care Activities and Diabetes Communication. The mean scores on Collaboration with Parents show an incremental decline in collaboration with parents as adolescents move through stages. The higher mean Diabetes Problem Solving scores found in the late adolescent group compared correlated with a higher degree of problem solving in this group when compared to those in the early or middle adolescent stage group. Regimen had significant associations with three of the five subscales suggesting this is an important variable for future study. DOI did not have a significant impact on self-management whereas gender related differences in the areas of Diabetes Activities and Diabetes communication warrant further investigation.

The focus of this study is the problem of declining trend in obstructive sleep apnea (OSA) patient compliance. Studies reported improved compliance in patients with chronic diseases due to technology-based interventions. However, researchers have not investigated the advantages of technology to improve the compliance of OSA patients in detail. The specific problem was the lack of engagement between patients and healthcare managers, resulting in low compliance within OSA patients. The purpose of this qualitative study was to evaluate how technology-based interventions can improve OSA patient engagement with the healthcare managers resulting in improved compliance with treatment procedures. In this study, the technology acceptance model was used as the instrument in evaluating the information collected through interviews with 20 healthcare managers about their attitudes toward usage, perceived usefulness, and perceived ease of use. The transcribed interviews were open-coded using the RQDA library in R Studio. In general, results from this study indicated that the healthcare managers showed a positive attitude towards the use of technology for patient engagement and expressed that the technology is useful for patient engagement and is easier to use. However, they identified technology-related and patient-related challenges in implementing technology for patient engagement. Further, the respondents identified process-related and patient-related opportunities in using technology for patient engagement. Results from this study have practice and policy implications by enabling healthcare managers to devise better compliance plans for OSA patient management. The findings could have a social benefit by helping healthcare managers to implement technology-based interventions to better achieve a higher compliance resulting in better patient health at lower costs.

Indiana University-Purdue University Indianapolis (IUPUI) / People with severe mental illness (SMI) often suffer from comorbid physical conditions that result in chronic morbidity and early mortality. Physical health decision-making is one area that has been largely unexplored with the SMI population. This study aimed to identify what factors contribute to the physical healthcare decision-making autonomy preferences of persons with SMI, and to identify the impact of these autonomy preferences on medication adherence. Ninety-five adults with SMI were recruited from an integrated care clinic located in a community mental health center. Fifty-six completed a three-month follow-up. Multiple linear regression for hypothesis 1 (n=95) and hierarchical regression for hypothesis 2 (n=56) were used to analyze data on personal characteristics, physical health decision-making autonomy preferences and medication adherence. For the open-ended questions, thematic analysis was used to uncover facilitators and barriers to medication adherence. With this sample, being male predicted greater desired autonomy, and having less social support predicted less desired autonomy. When background characteristics were held constant, autonomy preferences and perceived autonomy support from the physician only contributed an additional 1% of the variance in medication adherence. Lastly, participants reported behavioral factors and having family/personal support to take medications as facilitators to medication adherence for physical health care, while citing financial and other resource limitations as barriers.
