Task sharing for the management of leprosy by nurses in a tertiary healthcare setting of Northern India.

BACKGROUND: This study aimed to assess the effectiveness of nurse-led interventions in managing leprosy due to a shortage of dermatologists and other healthcare professionals. METHODS: A total of 100 leprosy patients were divided into experimental (n=50) and control groups (n=50). The intervention included face-to-face counseling by a trained nurse, motivational videos and exercise demonstrations. The control group received standard care. The primary outcome of interest was treatment adherence (Adherence to Refills and Medications Scale); other assessed outcomes included changes in perceived stigma (Stigma Assessment and Reduction of Impact scale), depression (Patient Health Questionnaire-9), anxiety (Generalized Anxiety Disorder seven-item) and quality of life (WHO QOL-BREF Scale) from baseline to week 8. RESULTS: The intervention group had better treatment adherence (p<0.001). At baseline, moderately severe and severe depression prevalence was 18% and 28%, respectively, and anxiety was 25%, with no intergroup differences. Anxiety significantly decreased in the intervention group (p<0.001), but depression remained similar (p=0.291). Perceived stigma improved notably, especially in disclosure of concern (p<0.001), internal stigma (p<0.001) and anticipated stigma (p<0.001). Quality of life scores improved in the intervention group vs controls. CONCLUSION: Nurse-led interventions effectively enhanced quality of life and treatment adherence and reduced anxiety, depression and perceived stigma among leprosy patients. The study recommends strengthening the capacity of nurses for active involvement in leprosy care.

Perceived appropriateness of medication adherence incentives.

BACKGROUND: 50% of prescriptions dispensed in the United States are not taken as prescribed, leading to approximately 125,000 deaths and 10% of hospitalizations per year. Incentives are effective in improving medication adherence; however, information about patient perceptions regarding incentives is lacking. OBJECTIVES: To (1) explore perceived appropriateness of incentives among patients prescribed at least 1 medication for chronic hypertension, hyperlipidemia, heart disease, diabetes, and/or asthma/chronic obstructive pulmonary disease and (2) examine associations between perceived appropriateness and patient characteristics. METHODS: A cross-sectional online survey was administered via Qualtrics Panels to US adults taking at least 1 prescription medication for a chronic condition. The results describe patient preference for financial or social recognition-based incentive, perceived appropriateness of adherence incentives (5-point Likert scale), self-reported adherence (Medometer), and demographics. Analyses included descriptive statistics with chi-square and independent t-tests comparing characteristics between participants who perceived incentives as being appropriate or inappropriate and logistic regression to determine predictors of perceived appropriateness. RESULTS: 1,009 individuals completed the survey. Of the 1,009 total survey participants, 933 (92.5%) preferred to receive a financial (eg, cash, gift card, or voucher) rather than a social recognition-based incentive (eg, encouraging messages, feedback, individual recognition, or team competition) for medication adherence. 740 participants (73%) perceived medication adherence incentives as being appropriate or acceptable as a reward given for taking medications at the right time each day, whereas 95 (9%) perceived incentives as being inappropriate. Remaining participants were neutral. Hispanic ethnicity (OR = 0.57; 95% CI = 0.37-0.89); income under $75,000 (OR = 0.48; 95% CI = 0.28-0.84); no college degree (OR = 0.60; 95% CI = 0.37-0.96); and adherence (OR = 0.99; 95% CI = 0.98-0.99) were significant predictors. CONCLUSIONS: The majority of patients perceived incentives as appropriate and preferred financial incentives over social recognition-based incentives. Perceived appropriateness for medication adherence incentives was less likely among certain groups of patients, such as those with Hispanic ethnicity, lower annual income, no college degree, and higher levels of adherence. These characteristics should be taken into account when structuring incentives. DISCLOSURES: This study was funded by the Auburn University's Intramural Grants Program.

Improving treatment outcomes for leprosy in Pernambuco, Brazil: a qualitative study exploring the experiences and perceptions of retreatment patients and their carers.

BACKGROUND: Brazil has a high leprosy burden and poor treatment outcomes (TOs), manifesting in high relapse rates. Pernambuco, an impoverished Brazilian state suffering notable geographical health inequalities, has 'hyperendemic' leprosy. Although current literature identifies barriers and facilitators influencing leprosy treatment compliance, inadequate investigation exists on other factors influencing TOs, including carers' roles and psycho-dermatological impact. This qualitative study explores experiences and perceptions of leprosy patients and their carers in Pernambuco, Brazil; to identify location-specific factors influencing TOs, and consequently inform future management. METHODS: 27, semi-structured, in-depth interviews were conducted with 14 patients and 13 carers. Participants were recruited using maximum variation and snowball sampling from three clinics in Petrolina, Pernambuco. Transcripts and field notes from both participant groups were separately analysed using conventional thematic and deviant case analysis. The University of Birmingham Internal Research Ethics Committee and Instituto Lauro de Souza Lima provided ethical approval. RESULTS: Two homologous sets of four, primary, interdependent themes influencing leprosy TOs emerged: 'personal factors'; 'external factors'; 'clinical factors'; and 'the healthcare professional (HCP)-patient-carer relationship'. Poor participant knowledge and lack of symptomatic relief caused patients to distrust treatment. However, because participants thought HCP-led interventions were vital for optimal TOs, patients were effectively persuaded to adhere to pharmaceutical treatments. High standard patient and population education facilitated treatment engagement by encouraging evidence-based medicine belief, and dispelling health myths and stigma. Healthcare, on occasions, was perceived as disorganised, particularly in resource-scarce rural areas, and for those with mental health needs. Participants additionally experienced incorrect/delayed diagnoses and poor contact tracing. Leprosy's negative socio-economic impact on employment - together with stigma, dependency and changing relationships - caused altered senses of identity, negatively impacting TOs. Better dialogue between patients, HCPs and carers facilitated individualised patient support. CONCLUSION: This study highlights the importance of: effective evidence-based leprosy education; communication between HCPs, patients and carers; state-funded support; and healthcare resource distribution. These findings, if prioritised on governmental scales, provide the valuable insight needed to inform location-specific management strategies, and consequently improve TOs. Future research should evaluate the effectiveness of these implementations. Failure to address these findings will hinder regional elimination efforts.

Ofloxacin-Containing Multidrug Therapy in Ambulatory Leprosy Patients: A Case Series.

BACKGROUND: Standard dapsone and clofazimine-containing multidrug therapy (MDT) for leprosy is limited by drug tolerability, which poses treatment adherence barriers. Although ofloxacin-based regimens are promising alternatives, current efficacy and safety data are limited, particularly outside of endemic areas. We evaluated treatment outcomes in patients with leprosy receiving ofloxacin-containing MDT (OMDT) at our center. METHODS: We performed a retrospective chart review of patients treated for leprosy at our center over an 8-year period (2011-2019). Primary outcomes evaluated were clinical cure rate, occurrence of leprosy reactions, antibiotic-related adverse events, and treatment adherence. Analyses were descriptive; however, data were stratified by age, sex, spectrum of disease, region of origin, and treatment regimen, and odds ratios were reported to assess associations with adverse outcomes. RESULTS: Over the enrolment period, 26 patients were treated with OMDT (n = 19 multibacillary, n = 7 paucibacillary), and none were treated with clofazimine-based standard MDT. At the time of analysis, 23 patients (88%) had completed their course of treatment, and all were clinically cured, while 3 (12%) were still on treatment. Eighteen patients (69%) experienced either ENL (n = 7, 27%), type 1 reactions (n = 7, 27%), or both (n = 4, 15%). No patients stopped ofloxacin due to adverse drug effects, and there were no cases of allergic hypersensitivity, tendinopathy or rupture, or C. difficile colitis. CONCLUSIONS: We demonstrate a high cure rate and tolerability of OMDT in this small case series over an 8-year period, suggesting its viability as an alternative to standard clofazimine-containing MDT.

Adherence to the MDR-TB intensive phase treatment protocol amongst individuals followed up at central and peripheral health care facilities in Uganda - a descriptive study.

BACKGROUND: Following initiation of MDR-TB treatment, patients have a choice to receive follow up DOT supervision at either the central initiating facility or at a peripheral facility. OBJECTIVES: We describe the adherence patterns of MDR-TB patients undergoing DOT supervision at the two health facility categories during intensive phase of treatment. METHODS: We used a retrospective cohort of patients initiated on MDR TB treatment at Mulago National Referral Hospital between 2014 and 2016. We extracted data from the National Tuberculosis and Leprosy Program records and analysed these using STATA V14. RESULT: Majority (84.01%) of the patients received their DOT supervision from the peripheral facilities. Males made up 62.1% of patients, and 91.2% had had their household contacts screened for MDR-TB. 26.5% of the patients on peripheral DOT supervision had good adherence to treatment protocol compared to 0% among patients on central initiating health facility DOT supervision. Among the patients with good adherence, 24.1% had contacts screened for MDR-TB as compared to 3.6% with poor adherence. CONCLUSION: More patients preferred MDR-TB DOT supervision at peripheral facilities, which had better adherence to the treatment protocol compared to the central initiating facility. Younger people and those with household contacts screened had better adherence to the treatment protocol, highlighting areas for targeted interventional programs for MDR-TB in resource limited settingsMore patients preferred MDR-TB DOT supervision at peripheral facilities, which had better adherence to the treatment protocol compared to the central initiating facility. Younger people and those with household contacts screened had better adherence to the treatment protocol, highlighting areas for targeted interventional programs for MDR-TB in resource limited settings.

A prospective study of the epidemiological and clinical patterns of recurrent dermatophytosis at a tertiary care hospital in India.

BACKGROUND: Recurrent and clinically unresponsive dermatophytosis is being increasingly encountered in our country. It runs a protracted course with exacerbations and remissions. However, there is little information regarding the extent of the problem and the characteristics of recurrent dermatophytosis in published literature. AIMS: We sought to determine the prevalence, risk factors and clinical patterns of recurrent dermatophytosis in our institution. We also investigated the causative dermatophyte species and antifungal susceptibility patterns in these species. METHODS: One hundred and fifty patients with recurrent dermatophytosis attending the outpatient department of the Postgraduate Institute of Medical Education and Research, Chandigarh, India were enrolled in the study conducted from January 2015 to December 2015. A detailed history was obtained in all patients, who were then subjected to a clinical examination and investigations including a wet preparation for direct microscopic examination, fungal culture and antifungal susceptibility tests. RESULTS: Recurrent dermatophytosis was seen in 9.3% of all patients with dermatophytosis in our study. Trichophyton mentagrophytes was the most common species identified (36 patients, 40%) samples followed by T. rubrum (29 patients, 32.2%). In-vitro antifungal susceptibility testing showed that the range of minimum inhibitory concentrations (MIC) on was lowest for itraconazole (0.015-1), followed by terbinafine (0.015-16), fluconazole (0.03-32) and griseofulvin (0.5-128) in increasing order. LIMITATION: A limitation of this study was the absence of a suitable control group (eg. patients with first episode of typical tinea). CONCLUSION: Recurrence of dermatophytosis was not explainable on the basis of a high (MIC) alone. Misuse of topical corticosteroids, a high number of familial contacts, poor compliance to treatment over periods of years, and various host factors, seem to have all contributed to this outbreak of dermatophytosis in India.

A cross-sectional study to assess the stigma associated with tuberculosis among tuberculosis patients in Udupi district, Karnataka.

BACKGROUND: For decades, tuberculosis and other communicable diseases like human immunodeficiency virus/acquired immune deficiency syndrome, leprosy, etc., have been associated with stigma and discrimination by the society; this can interfere with the lifestyle and disease management among these patients. OBJECTIVE: To assess the stigma experienced by tuberculosis patients and to find the factors associated with stigma. METHODS: A cross-sectional study was conducted among 209 sputum-positive and sputum-negative tuberculosis patients. Convenient sampling was used to identify the patients. A predesigned, pretested proforma from Explanatory Model Interview Catalogue developed by World Health Organization was used for data collection. RESULTS: The study revealed that out of 209 respondents, 51.2% of the respondents experienced some form of stigma. Majority of the patients have received only primary education and 71.3% of the respondents were males. Most of the patients were under category 1 of Directly Observed Treatment Short course. Age, education, and smear status of the patient were found to be associated with stigmatization (P<0.05), whereas factors like gender, income, occupation, family history, and marital status were found to be not significantly associated with stigmatization. CONCLUSION: Effective counseling measures are recommended for tuberculosis patients with advancing age and education which can help reduce stigmatization and thereby improve quality of life.

Factors Associated with Adherence to Adjuvant Endocrine Therapy Among Privately Insured and Newly Diagnosed Breast Cancer Patients: A Quantile Regression Analysis.

BACKGROUND: Adherence to adjuvant endocrine therapy (AET) for estrogen receptor-positive breast cancer remains suboptimal, which suggests that women are not getting the full benefit of the treatment to reduce breast cancer recurrence and mortality. The majority of studies on adherence to AET focus on identifying factors among those women at the highest levels of adherence and provide little insight on factors that influence medication use across the distribution of adherence. OBJECTIVE: To understand how factors influence adherence among women across low and high levels of adherence. METHODS: A retrospective evaluation was conducted using the Truven Health MarketScan Commercial Claims and Encounters Database from 2007-2011. Privately insured women aged 18-64 years who were recently diagnosed and treated for breast cancer and who initiated AET within 12 months of primary treatment were assessed. Adherence was measured as the proportion of days covered (PDC) over a 12-month period. Simultaneous multivariable quantile regression was used to assess the association between treatment and demographic factors, use of mail order pharmacies, medication switching, and out-of-pocket costs and adherence. The effect of each variable was examined at the 40th, 60th, 80th, and 95th quantiles. RESULTS: Among the 6,863 women in the cohort, mail order pharmacies had the greatest influence on adherence at the 40th quantile, associated with a 29.6% (95% CI = 22.2-37.0) higher PDC compared with retail pharmacies. Out-of-pocket cost for a 30-day supply of AET greater than $20 was associated with an 8.6% (95% CI = 2.8-14.4) lower PDC versus $0-$9.99. The main factors that influenced adherence at the 95th quantile were mail order pharmacies, associated with a 4.4% higher PDC (95% CI = 3.8-5.0) versus retail pharmacies, and switching AET medication 2 or more times, associated with a 5.6% lower PDC versus not switching (95% CI = 2.3-9.0). CONCLUSIONS: Factors associated with adherence differed across quantiles. Addressing the use of mail order pharmacies and out-of-pocket costs for AET may have the greatest influence on improving adherence among those women with low adherence.

Correlates of Defaulting from MDT among Leprosy Patients.

In order to analyse the factors of demographic as well as disease related variables and their correlation with Rate of Defaulting (ROD) from Multi Drug Therapy (MDT) among leprosy patients, secondary data have been collected from 3,579 new cases registered for MDT, during a period of 4 years from 2007 to 2010 in four leprosy hospitals/ treatment centers across the four high endemic states viz. Uttar Pradesh, Chhattisgarh; Maharashtra and Andhra Pradesh. Year wise percentage of patients defaulted was calculated on aggregate as well as with reference to each centre and cross tabulated with demographic and disease related factors. Findings show that out of the total 3,579 new cases, 1944,(54.3%) defaulted with variation across centers ranged from 44 to 66 percent. Comparison of ROD against type of leprosy indicated that MB types defaulted (55.7%) more than PB (50.6%) types, (statistically significant difference, (p=0,04). ROD of male patients across the centers ranged from 45% to 67.7% in comparison with 42.4% to 61.5% of female patients. A-statistically significant difference (p=6.04) was found between the overall ROD of males (56.35%) and females (51.47%). The ROD among those with more severe disabilities (WHO Gr-2) ranged between 44% to 67.5% across the centers, while the same among those'with less severe disabilities (Gr-0&1) ranged from 42.6 to 72.7 percent. Comparison of ROD against severity of disability was found statistically significant only across 2 centers. No statistically significant variation was found when ROD of adult patients with refeince to each centr ranged between (43.6% to 65.4%) was compared with the same of children ranged beeIen (36.2% to 69.3%). Across each of these categories and centers,'the ROD remained consistent over the ,4 years. Based on the above findings'this may be concluded that male sex and MB types are significant correlates of default from treatment. Severity of disabilities plays significant role only in certain areas, probably due to other interfering factors, which needs to be further investiged.

What stops people completing multi-drug therapy? Ranked perspectives of people with leprosy, their head of family and neighbours--across four Indian states.

UNLABELLED: Summary To maximise successful completion of multi-drug therapy (MDT) and optimise treatment outcomes for people with leprosy, it is vital to understand the relative importance of perceived factors which prevent them from completing the required number of doses in time. OBJECTIVE: To explore personal, family, social, community, attitudinal, practical, geographical, cultural and traditional factors which may influence adherence to treatment, a two-phase study was undertaken comprising issue identification via focus groups, and a ranking exercise via individual interview. STUDY DESIGN: The perspectives of 895 respondents (320 people affected by leprosy who were not able to complete treatment, 302 of their 'operational heads of family', and 273 of their nearby community members) across four states of India namely i.e. Andhra Pradesh (Salur), Chhattisgarh (Chandkhuri), Maharashtra (Kothara) and Uttar Pradesh (Barabanki) were collected, using a checklist interview method. RESULTS: Findings suggest that seeing positive changes in their symptoms as well as not seeing improvement can lead to non-completion of MDT. Problems with scheduling and travel expenses were also key issues. Better management of the expectations of people affected by leprosy and reducing the burden of treatment may be important strategies. The importance of stigma and poverty were noted through a number of issues, none of which were particularly highly ranked. CONCLUSIONS: The nature and diversity of perceived issues identified across respondent type and particularly region, suggest that the determinants of adherence are complex and multi-factorial. More community based approaches with greater coordination at the community level are recommended.

Validation of indirect tuberculosis treatment adherence measures in a resource-constrained setting.

SETTING: Arusha, Mwanza, Mufindi and Kilosa in Tanzania. OBJECTIVE: To assess the test characteristics of three indirect adherence measures against a gold standard of direct measurements of drug intake for use in a resource-constrained setting. METHODS: We assessed sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV), and the diagnostic odds ratio (dORs) of three indirect adherence measurement tools against direct measurement in urine using the IsoScreen assay. RESULTS: The single adherence question of missed doses in the last 2 days had the highest dOR (40.3) compared to the Morisky medication adherence scale (MMAS, 2.5) and pill counts (3.4). The sensitivities of these measures were respectively 97.9%, 92% and 89.6%. Specificity ranged from 46.4% (adherence question) to 17.9% (MMAS). The PPVs of adherence question, pill counts and MMAS were respectively 97.6%, 96.5% and 94.2%, while the NPVs ranged from 50% (adherence question) to 3.1% (MMAS). CONCLUSION: Among several instruments for indirect adherence measure in the routine setting of the Tanzanian National Tuberculosis and Leprosy Programme, a single adherence question was found to have the best discriminatory power. However, the single adherence question might not adequately identify patients who are non-adherent. Confirmatory studies are needed, especially in settings with low adherence rates.

Rifampicin-resistant Mycobacterium leprae in an elderly leprosy patient in the people's Republic of China.

The reported number of registered leprosy patients worldwide declined with the introduction of multidrug therapy. However, the emergence of rifampicin resistance in leprosy patients engenders difficulties for an individual patient, and its dissemination could pose a threat to leprosy control. This study reports an elderly patient who was diagnosed with rifampicin-resistant lepromatous leprosy. This case indicates that inadequate treatment and poor compliance may eventually result in rifampicin resistance in Mycobacterium leprae and clinical relapse.

Assessing and improving adherence with multidrug therapy.

INTRODUCTION: Adherence with multidrug therapy (MDT) in the treatment of leprosy is important to minimise the risk of relapse and avoid the emergence of drug resistance. Adherence is defined as the extent to which the patient's behaviour matches recommendations from the prescriber. This paper reviews the methods for assessing adherence with MDT in leprosy, and community approaches to improving adherence based on evidence from the treatment of tuberculosis (TB) and HIV, as well as leprosy. METHODS: To identify and summarise the available literature regarding the assessment of treatment regularity in leprosy, a literature search of MEDLINE was conducted using the following search terms: 'leprosy' AND ('adherence' OR 'compliance' OR 'concordance'). To identify evidence for interventions that have involved community members in HIV, TB or leprosy adherence support, a literature search was conducted using the key terms and medical subject headings 'treatment or adherence' 'community,' 'HIV, TB or Leprosy' and 'low and middle income countries' combined using Boolean operators. RESULTS: Leprosy programmes routinely use defaulting and treatment completion as proxy measures of adherence as recommended by the WHO global strategy. However, a number of other methods have been used to assess adherence including questionnaires, pill counts, as well as direct measures based on testing urine for the presence of dapsone. Direct methods were extensively used during the dapsone mono-therapy era but there is little evidence of their use in MDT. Use of multiple methods of assessing adherence improves the accuracy and reliability of the results. Community activities in TB and HIV such as variants of treatment observation, and/or wider programmes of counselling or direct support to the patient or their family or to increase community or social support were shown to improve treatment outcomes. Outcomes evaluated included treatment default and completion, clinical indicators, and adherence (pill-count, self report). CONCLUSIONS: Adherence is very important in leprosy and regular assessment of medication adherence together with constructive feedback and counselling of patients is likely to be beneficial. Leprosy programme can learn from adherence support interventions developed by both TB and HIV programmes.

Qualitative assessment of medication adherence at an urban leprosy outpatient clinic in Hyderabad, India.

OBJECTIVES: The objective of this study was to measure medication adherence amongst outpatients attending an urban leprosy clinic in Hyderabad, India. DESIGN: In this study of observational design, the urine spot test and Morisky Scale questionnaire were concurrently used as qualitative measures of medication adherence. RESULTS: Fifty two patients met the inclusion criteria for this study; 13 patients (25%) were non-adherent according to the Morisky scale questionnaire and 17 patients (33%) according to the urine spot test. 48% of patients were non-adherent on the basis of the urine spot test and/or the Morisky scale questionnaire. CONCLUSION: The results suggest that poor medication adherence remains an ongoing issue in the management of outpatients with leprosy.

Interruption and defaulting of multidrug therapy against leprosy: population-based study in Brazil's Savannah Region.

BACKGROUND: Low adherence to multidrug therapy against leprosy (MDT) is still an important obstacle of disease control, and may lead to remaining sources of infection, incomplete cure, irreversible complications, and multidrug resistance. METHODOLOGY/PRINCIPAL FINDING: We performed a population-based study in 78 municipalities in Tocantins State, central Brazil, and applied structured questionnaires on leprosy-affected individuals. We used two outcomes for assessment of risk factors: defaulting (not presenting to health care center for supervised treatment for >12 months); and interruption of MDT. In total, 28/936 (3.0%) patients defaulted, and 147/806 (18.2%) interrupted MDT. Defaulting was significantly associated with: low number of rooms per household (OR = 3.43; 0.98-9.69; p = 0.03); moving to another residence after diagnosis (OR = 2.90; 0.95-5.28; p = 0.04); and low family income (OR = 2.42; 1.02-5.63: p = 0.04). Interruption of treatment was associated with: low number of rooms per household (OR = 1.95; 0.98-3.70; p = 0.04); difficulty in swallowing MDT drugs (OR = 1.66; 1.03-2.63; p = 0.02); temporal non-availability of MDT at the health center (OR = 1.67; 1.11-2.46; p = 0.01); and moving to another residence (OR = 1.58; 95% confidence interval: 1.03-2.40; p = 0.03). Logistic regression identified temporal non-availability of MDT as an independent risk factor for treatment interruption (adjusted OR = 1.56; 1.05-2.33; p = 0.03), and residence size as a protective factor (adjusted OR = 0.89 per additional number of rooms; 0.80-0.99; p = 0.03). Residence size was also independently associated with defaulting (adjusted OR = 0.67; 0.52-0.88; p = 0.003). CONCLUSIONS: Defaulting and interruption of MDT are associated with some poverty-related variables such as family income, household size, and migration. Intermittent problems of drug supply need to be resolved, mainly on the municipality level. MDT producers should consider oral drug formulations that may be more easily accepted by patients. Thus, an integrated approach is needed for further improving control, focusing on vulnerable population groups and the local health system.
