Patient and caregiver perspectives on early identification for advance care planning in primary healthcare settings.

BACKGROUND: As part of a broader study to improve the capacity for advance care planning (ACP) in primary healthcare settings, the research team set out to develop and validate a computerized algorithm to help primary care physicians identify individuals at risk of death, and also carried out focus groups and interviews with relevant stakeholder groups. Interviews with patients and family caregivers were carried out in parallel to algorithm development and validation to examine (1) views on early identification of individuals at risk of deteriorating health or dying; (2) views on the use of a computerized algorithm for early identification; and (3) preferences and challenges for ACP. METHODS: Fourteen participants were recruited from two Canadian provinces. Participants included individuals aged 65 and older with declining health and self-identified caregivers of individuals aged 65 and older with declining health. Semi-structured interviews were conducted via telephone. A qualitative descriptive analytic approach was employed, which focused on summarizing and describing the informational contents of the data. RESULTS: Participants supported the early identification of patients at risk of deteriorating health or dying. Early identification was viewed as conducive to planning not only for death, but for the remainder of life. Participants were also supportive of the use of a computerized algorithm to assist with early identification, although limitations were recognized. While participants felt that having family physicians assume responsibility for early identification and ACP was appropriate, questions arose around feasibility, including whether family physicians have sufficient time for ACP. Preferences related to the content of and approach to ACP discussions were highly individualized. Required supports during ACP include informational and emotional supports. CONCLUSIONS: This work supports the role of primary care providers in the early identification of individuals at risk of deteriorating health or death and the process of ACP. To improve ACP capacity in primary healthcare settings, compensation systems for primary care providers should be adjusted to ensure appropriate compensation and to accommodate longer ACP appointments. Additional resources and more established links to community organizations and services will also be required to facilitate referrals to relevant community services as part of the ACP process.

Stakeholders' views on identifying patients in primary care at risk of dying: a qualitative descriptive study using focus groups and interviews.

BACKGROUND: Strategies have been developed for use in primary care to identify patients at risk of declining health and dying, yet little is known about the perceptions of doing so or the broader implications and impacts. AIM: To explore the acceptability and implications of using a primary care-based electronic medical record algorithm to help providers identify patients in their practice at risk of declining health and dying. DESIGN AND SETTING: Qualitative descriptive study in Ontario and Nova Scotia, Canada. METHOD: Six focus groups were conducted, supplemented by one-on-one interviews, with 29 healthcare providers, managers, and policymakers in primary care, palliative care, and geriatric care. Participants were purposively sampled to achieve maximal variation. Data were analysed using a constant comparative approach. RESULTS: Six themes were prevalent across the dataset: early identification is aligned with the values, aims, and positioning of primary care; providers have concerns about what to do after identification; how we communicate about the end of life requires change; early identification and subsequent conversations require an integrated team approach; for patients, early identification will have implications beyond medical care; and a public health approach is needed to optimise early identification and its impact. CONCLUSION: Stakeholders were much more concerned with how primary care providers would navigate the post-identification period than with early identification itself. Implications of early identification include the need for a team-based approach to identification and to engage broader communities to ensure people live and die well post-identification.

Impact of a provincial quality-improvement program on primary health care in Ontario: a population-based controlled before-and-after study.

BACKGROUND: In Ontario, a province-wide quality-improvement program (Quality Improvement and Innovation Partnership [QIIP]) was implemented between 2008 and 2010 to support improved outcomes in Family Health Teams, a care model that includes many features of the patient-centred medical home. We assessed the impact of this program on diabetes management, colorectal and cervical cancer screening and access to health care. METHODS: We used comprehensive linked administrative data sets to conduct a population-based controlled before-and-after study. Outcome measures included diabetes process-of-care measures (test ordering, retinal examination, medication prescribing and completion of billing items specific to diabetes management), colorectal and cervical cancer screening measures and use of health care services (emergency department visits, hospital admission for ambulatory-care-sensitive conditions and rates of readmission to hospital). The control group consisted of Family Health Team physicians with at least 100 assigned patients during the study follow-up period (November 2009-February 2013). RESULTS: There were 53 physicians in the intervention group and 1178 physicians in the control group. Diabetes process-of-care measures improved more in the intervention group than in the control group: hemoglobin A1c testing 4.3% (95% confidence interval [CI] 1.2-7.5) more, retinal examination 2.5% (95% CI 0.8-4.4) more and preventive care visits 8.9% (95% CI 2.9-14.9) more. Medication prescribing also improved for use of statins (3.4% [95% CI 0.8-6.0] more) and angiotensin-converting-enzyme inhibitors or angiotensin receptor blockers (4.1% [95% CI 1.8-6.4] more). Colorectal cancer screening improved 5.4% (95% CI 3.1-7.8) more in the intervention group than in the control group, and cervical cancer screening improved 2.7% (95% CI 0.9-4.6) more. There were no significant differences in any of the measures of use of health care services. INTERPRETATION: This large controlled evaluation of a broadly implemented quality-improvement initiative showed improvement for diabetes process of care and cancer screening outcomes, but not for proxy measures of access related to use of health care services.

Impact of a primary healthcare quality improvement program on diabetes in Canada: evaluation of the Quality Improvement and Innovation Partnership (QIIP).

OBJECTIVE: Primary healthcare (PHC) quality improvement (QI) initiatives are designed to improve patient care and health outcomes. We evaluated the Quality Improvement and Innovation Partnership (QIIP), an Ontario-wide PHC QI program on access to care, diabetes management and colorectal cancer screening. This manuscript highlights the impact of QIIP on diabetes outcomes and associated vascular risk factors. RESEARCH DESIGN AND METHODS: A cluster matched-control, retrospective prechart and postchart audit was conducted. One physician per QIIP-PHC team (N=34) and control (N=34) were recruited for the audit. Eligible charts were reviewed for prespecified type 2 diabetes mellitus clinical process and outcome data at baseline, during (intervention range: 15-17.5 months) and post. Primary outcome measures were the A1c of patients above study target and proportion of patients with an annual foot exam. Secondary outcome measures included glycemic, hypertension and lipid outcomes and management, screening for diabetes-related complications, healthcare utilization, and diabetes counseling, education and self-management goal setting. RESULTS: More patients in the QIIP group achieved statistically improved lipid testing, eye examinations, peripheral neuropathy exams, and documented body mass index. No statistical differences in A1c, low-density lipoprotein or systolic/diastolic blood pressure values were noted, with no significant differences in medication prescription, specialist referrals, or chart-reported diabetes counseling, education or self-management goals. Patients of QIIP physicians had significantly more PHC visits. CONCLUSION: The QIIP-learning collaborative program evaluation using stratified random selection of participants and the inclusion of a control group makes this one of the most rigorous and promising efforts to date evaluating the impact of a QI program in PHC. The chart audit component of this evaluation highlighted that while QIIP improved some secondary diabetes measures, no improvements in clinical outcomes were noted. This study highlights the importance of formalized evaluation of QI initiatives to provide an evidence base to inform future program planning and scale-up.

Satisfaction with civilian family medicine residency training: Perspectives from serving general duty medical officers in the Canadian Armed Forces.

OBJECTIVE: To evaluate satisfaction with civilian residency training programs among serving general duty medical officers within the Canadian Armed Forces. DESIGN: A 23-item, cross-sectional survey face-validated by the office of the Surgeon General of the Canadian Armed Forces. SETTING: Canada. PARTICIPANTS: General duty medical officers serving in the Canadian Armed Forces as of February 2014 identified through the Directorate of Health Services Personnel of the Canadian Forces Health Services Group Headquarters. MAIN OUTCOME MEASURES: Satisfaction with and time spent in 7 domains of training: trauma, critical care, emergency medicine, psychiatry, occupational health, sports medicine, and base clinic training. Overall preparedness for leading a health care team, caring for a military population, working in isolated and challenging environments, and being deployed were evaluated on a 5-point Likert scale. RESULTS: Among the survey respondents (n = 135, response rate 54%), 77% agreed or strongly agreed that their family medicine residency training was relevant to their role as a general duty medical officer. Most respondents were either satisfied or very satisfied with their emergency medicine training (77%) and psychiatry training (63%), while fewer were satisfied or very satisfied with their sports medicine (47%), base clinic (41%), and critical care (43%) training. Even fewer respondents were satisfied or very satisfied with their trauma (26%) and occupational health (12%) training. Regarding overall preparedness, 57% believed that they were adequately prepared to care for a military patient population, and 52% of respondents believed they were prepared for their first posting. Fewer respondents (38%) believed they were prepared to work in isolated, austere, or challenging environments, and even fewer (32%) believed that residency training prepared them to lead a health care team. CONCLUSION: General duty medical officers were satisfied with many aspects of their family medicine residency training; however, military-specific areas for improvement were identified. Many of these areas might be addressed within the context of a 2-year residency program without risking the generalist nature of family medicine training. These findings provide valuable data for residency programs that accept military trainees across the country.

The role of the practice facilitators in Ontario primary healthcare quality improvement.

BACKGROUND: Practice facilitation is a key component of quality improvement in primary healthcare. Studies have reported the effectiveness of practice facilitation in improving quality management and care delivery. However, little has been published about practice facilitators' training, facilitation activities, and their perceived role in quality improvement in primary healthcare. This study examined practice facilitators' training and the perceptions of the practice facilitator role in a provincial primary healthcare learning collaborative quality improvement initiative in Ontario, Canada. METHOD: Descriptive and qualitative methods were used to outline the practice facilitator training as well as to look into the experiences and perceptions of practice facilitators and primary healthcare teams regarding the practice facilitation role in quality improvement. Data collection included training artifacts, activity logs, self-reflection reports, and semi-structured interviews with practice facilitators and primary healthcare participants. Reflections and interviews were analyzed to identify the role of the practice facilitators from their own experience, and from the perspective of the participants. Descriptive statistics were used to learn about categories of facilitation activities undertaken and frequency of these activities. RESULTS: Sixteen practice facilitators and seven family healthcare teams participated in the study. Practice facilitators received a two-day intensive training workshop and continued training. Their time was spent mostly working directly with participating teams, continued learning and training, communications and administration. They served as coaches, resource providers, enablers and motivators. Participating teams expressed satisfaction with the practice facilitator role, although they had hoped this position would provide onsite and hands-on support in conducting activities of quality improvement at the practice level. CONCLUSIONS: Practice facilitators played a crucial role in the implementation of quality improvement in Ontario's learning collaborative program. The practice facilitator role is perceived to be that of a coach, enabler and motivator. This study suggests that the practice facilitator successfully supported participating teams to undertake quality improvement activities in primary healthcare settings.

Teaching Quality Improvement in Graduate Medical Education: An Experiential and Team-Based Approach to the Acquisition of Quality Improvement Competencies.

PROBLEM: An emerging priority in medical education is the need to facilitate learners' acquisition of quality improvement (QI) competencies. Accreditation bodies in both Canada and the United States have included QI and patient safety in their core competencies. APPROACH: In 2010, the Department of Family Medicine at Queen's University designed a graduate medical education curriculum to engage residents in a clinical QI program that would meet accreditation requirements. Monthly didactic sessions were combined with an experiential, team-based QI project that aligned with existing clinic priorities. The curriculum spans the first year of residency and is divided into three stages: (1) Engaging, (2) Understanding, and (3) Improving and translating. In Stage 1, teams of residents select a clinical QI topic, engage stakeholders, and collect baseline data related to their topic. In Stage 2, they focus on understanding their problem, interpreting their results, and applying QI tools. In Stage 3, they develop change ideas, translate their knowledge, and prepare to hand over their project. OUTCOMES: This QI curriculum aided residents in effectively acquiring QI competencies and allowed them to experience real-world challenges, such as securing project buy-in, negotiating with peers, and developing solutions to problems. Unlike in many QI programs, residents learned how to improve quality rather than about QI; thus, they formed the necessary foundation to carry out QI work in the future. NEXT STEPS: The curriculum will be evaluated using a knowledge assessment and satisfaction tool and postproject resident interviews. Facilitators will focus more on improving faculty develop ment in QI.

Mindfulness-based stress reduction (MBSR) as sole intervention for non-somatisation chronic non-cancer pain (CNCP): protocol for a systematic review and meta-analysis of randomised controlled trials.

INTRODUCTION: Chronic non-cancer pain (CNCP) affects up to 50% of the world's population. It impacts negatively on quality of life; entailing high costs on our medical systems, and translates to economic burden due to work loss. Aetiology of CNCP is complex and multifactorial, embracing the somatosensory, cognitive and affective domains. Opioid analgesia and other invasive interventions are often inadequate for clinical management of CNCP. Recently, mindfulness-based stress reduction (MBSR) has become a popular therapy for various medical conditions, including CNCP. However, studies reported varying efficacies, and relevant systematic reviews have included clinical trials with inherent heterogeneity either in study conditions or types of interventions used. Our study aims to provide an updated and more critical evaluation of the efficacy of MBSR as the intervention for non-somatisation CNCP. METHODS AND ANALYSIS: A systematic review with meta-analysis of randomised controlled trials published in English will be performed in accordance with the Preferred Reporting Items for Systematic reviews and Meta-analyses (PRISMA) guidelines and the Cochrane Collaboration format. MEDLINE, EMBASE, PsychINFO, and the Cochrane Central Register of Controlled Trials Intervention, will be searched independently by reviewers using defined MeSH terms. Studies with full texts using MBSR as the main intervention on patients with non-somatising CNCP will be included. Outcome measures include pain scores and disability assessment scales. Continuous data will be meta-analysed using the RevMan 5 Review Manager programme. Primary analysis will adopt the random effects model in view of heterogeneity between trials. The standardised mean difference will be expressed as the effect size with 95% CIs. Forest plots, funnel plots, the I(2) statistic and the Cochrane Risks of Bias Assessment table will be included. ETHICS AND DISSEMINATION: No ethics approval is deemed necessary. Results of this study will be disseminated via peer-reviewed publications and scientific meetings. TRIALS REGISTRATION NUMBER: PROSPERO CRD42014015568.

Chronic obstructive pulmonary disease in primary care: an epidemiologic cohort study from the Canadian Primary Care Sentinel Surveillance Network.

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is mostly managed within primary care, but there is little Canadian evidence from this setting. This study was undertaken to determine the prevalence of physician-diagnosed COPD in primary care practices, and the degree of comorbidity with other chronic conditions, and to assess patterns of medication prescribing. METHODS: The Canadian Primary Care Sentinel Surveillance Network is a national "network of networks" whose member practices use electronic medical records (EMRs). At the time of the study, it included data from 444 physicians from 10 networks in 8 provinces. We conducted an epidemiologic cohort study of all patients who had EMR data collected by the network at the end of 2012. Validated case-finding algorithms were used to identify cases of COPD. We used descriptive statistics and multivariate modelling analyses to calculate the prevalence of COPD, its association with key demographic factors and comorbidities, and patterns of medication prescribing. RESULTS: The observed prevalence of COPD was 4.0% (10 043/250 346), which represents a population prevalence of 3.4% using age-sex standardization. Comorbidity was common, with prevalence ratios ranging from 1.1 for the presence of a single comorbid condition to 1.9 for 4 or more comorbid conditions. Anticholinergic agents (63%), short- (48%) and long-acting (38%) ß-agonists and inhaled corticosteroids (41%) were the most commonly used medications. INTERPRETATION: The prevalence of physician-diagnosed COPD in Canadian primary care practices was similar to that reported in other practice-based studies at about 3%-4%. Most patients had comorbid conditions and were taking multiple medications. EMR data may be useful to assess both the epidemiology and management of COPD in primary care practices.

Influence of a quality improvement learning collaborative program on team functioning in primary healthcare.

Quality improvement (QI) programs are frequently implemented to support primary healthcare (PHC) team development and to improve care outcomes. In Ontario, Canada, the Quality Improvement and Innovation Partnership (QIIP) offered a learning collaborative (LC) program to support the development of interdisciplinary team function and improve chronic disease management, disease prevention, and access to care. A qualitative study using a phenomenological approach was conducted as part of a mixed-method evaluation to explore the influence of the program on team functioning in participating PHC teams. A purposive sampling strategy was used to identify PHC teams (n = 10), from which participants of different professional roles were selected through a purposeful recruitment process to reflect maximum variation of team roles. Additionally, QI coaches working with the interview participants and the LC administrators were also interviewed. Data were collected through semistructured telephone interviews that were audiotaped and transcribed verbatim. Thematic analysis was conducted through an iterative and interpretive approach. The shared experience of participating in the program appeared to improve team functioning. Participants described increased trust and respect for each other's clinical and administrative roles and were inspired by learning about different approaches to interdisciplinary care. This appeared to enhance collegial relationships, collapse professional silos, improve communication, and increase interdisciplinary collaboration. Teamwork involves more than just physically grouping healthcare providers from multiple disciplines and mandating them to work together. The LC program provided opportunities for participants to learn how to work collaboratively, and participation in the LC program appeared to enhance team functioning.

Impact of a quality improvement program on primary healthcare in Canada: a mixed-method evaluation.

PURPOSE: Rigorous comprehensive evaluations of primary healthcare (PHC) quality improvement (QI) initiatives are lacking. This article describes the evaluation of the Quality Improvement and Innovation Partnership Learning Collaborative (QIIP-LC), an Ontario-wide PHC QI program targeting type 2 diabetes management, colorectal cancer (CRC) screening, access to care, and team functioning. METHODS: This article highlights the primary outcome results of an external retrospective, multi-measure, mixed-method evaluation of the QIIP-LC, including: (1) matched-control pre-post chart audit of diabetes management (A1c/foot exams) and rate of CRC screening; (2) post-only advanced access survey (third-next available appointment); and (3) post-only semi-structured interviews (team functioning). RESULTS: Chart audit data was collected from 34 consenting physicians per group (of which 88% provided access data). Between-group differences were not statistically significant (A1c [p=0.10]; foot exams [p=0.45]; CRC screening [p=0.77]; advanced access [p=0.22]). Qualitative interview (n=42) themes highlighted the success of the program in helping build interdisciplinary team functioning and capacity. CONCLUSION: The rigorous design and methodology of the QIIP-LC evaluation utilizing a control group is one of the most significant efforts thus far to demonstrate the impact of a QI program in PHC, with improvements over time in both QIIP and control groups offering a likely explanation for the lack of statistically significant primary outcomes. Team functioning was a key success, with team-based chronic care highlighted as pivotal for improved health outcomes. Policy makers should strive to endorse QI programs with proven success through rigorous evaluation to ensure evidence-based healthcare policy and funding.

The diagnosis of depression and its treatment in Canadian primary care practices: an epidemiological study.

BACKGROUND: A diagnosis of depression is common in primary care practices, but data are lacking on the prevalence in Canadian practices. We describe the prevalence of the diagnosis among men and women, patient characteristics and drug treatment in patients diagnosed with depression in the primary care setting in Canada. METHODS: Using electronic medical record data from the Canadian Primary Care Sentinel Surveillance Network, we examined whether the prevalence of a depression diagnosis varied by patient characteristics, the number of chronic conditions and the presence of the following chronic conditions: hypertension, diabetes, chronic obstructive pulmonary disease, osteoarthritis, dementia, epilepsy and parkinsonism. We used regression models to examine whether patient characteristics and type of comorbidity were associated with a depression diagnosis. RESULTS: Of the 304 412 patients who had at least 1 encounter with their primary care provider between Jan. 1, 2011, and Dec. 31, 2012, 14% had a diagnosis of depression. Current or past smokers and women with a high body mass index had higher rates of depression. One in 4 patients with a diagnosis of depression also had another chronic condition; those with depression had 1.5 times more primary care visits. About 85% of patients with depression were prescribed medication, most frequently selective serotonin reuptake inhibitors, followed by atypical antipsychotics. INTERPRETATION: Our data provide information on the prevalence of a depression diagnosis in primary care and associations with being female, having a chronic condition, smoking history and obesity in women. Our findings may inform research and assist primary care providers with early detection and interventions in at-risk patient populations.

Social isolation in older adults who are frequent users of primary care services.

OBJECTIVE: To describe older adults who are frequent users of primary care services and to explore associations between the number of primary care visits per year and multiple dimensions that define social isolation. DESIGN: Mailed, cross-sectional survey. SETTING: An urban academic primary care practice in Kingston, Ont. PARTICIPANTS: Forty patients aged 70 years and older who attended 12 or more appointments in the previous year with residents, physicians, nurses, nurse practitioners, or registered practical nurses. MAIN OUTCOME MEASURES: Social isolation (size of close social network, loneliness, satisfaction with social participation, frequency of social participation), past and future need for health services related to social issues, and health and functional variables. RESULTS: The participants reported relatively low levels of loneliness, with a mean (SD) score of 4.1 (1.3) out of 9. Overall, 18.9% of participants reported having a small close social network, 45.9% of participants wanted to do more social activities, and 57.5% of participants were isolated according to at least 1 indicator. Some participants (23.1%) had received primary care services related to social issues, and most participants (54.5%) wanted these services in the future, including receiving information about other health services or community resources, or having discussions about loneliness, relationships, or social activities. Number of primary care visits was not associated with any of the 4 indicators of social isolation. CONCLUSION: Social isolation in older, frequent users of primary care services might be more common than previously thought, particularly the aspect of dissatisfaction with social participation. Expanded primary care services and referrals to other services might help to address this population's desires for services related to social issues. Future research could examine the social needs of older primary care attenders and the feasibility of providing related interventions in primary care settings.

Evaluating the effectiveness of a physical activity referral scheme among women.

Evidence supports the effectiveness of interventions delivered in primary care to promote physical activity (PA). Specifically, approaches where physician counseling is coupled with other strategies (eg, referrals to community resources) have been recognized as the most promising. The purpose of this study was to compare the effectiveness of a PA prescription plus referral intervention versus a prescription only intervention delivered in primary care. Ten family physicians and their female patients (N = 35, mean age = 36 years) were randomly assigned to 1 of 3 conditions: prescription plus (n = 12), prescription only (n = 12), and usual care (n = 11). The prescription plus group received a PA prescription plus a referral to a community program, the prescription only group received only the PA prescription, and the usual care group received usual health care. The Godin Leisure-Time Exercise Questionnaire was used to measure PA. A significant increase on the PA score (P < .05, partial η(2) = .178) and on total weekly PA minutes (P < .05, partial η(2) = .179) was observed in both prescription groups after the intervention. There were no significant group differences (P > .05). No PA changes were observed in the usual care group. Findings from this pilot study suggest that brief PA counseling and a prescription delivered in primary care can be effective for promoting PA among women. Referring patients did not seem to enhance the effect on PA.

Ethics and privacy issues of a practice-based surveillance system: need for a national-level institutional research ethics board and consent standards.

OBJECTIVE: To describe the challenges the Canadian Primary Care Sentinel Surveillance Network (CPCSSN) experienced with institutional research ethics boards (IREBs) when seeking approvals across jurisdictions and to provide recommendations for overcoming challenges of ethical review for multisite and multijurisdictional surveillance and research. BACKGROUND: The CPCSSN project collects and validates longitudinal primary care health information (relating to hypertension, diabetes, depression, chronic obstructive lung disease, and osteoarthritis) from electronic medical records across Canada. Privacy and data storage security policies and processes have been developed to protect participants' privacy and confidentiality, and IREB approval is obtained in each participating jurisdiction. Inconsistent interpretation and application of privacy and ethical issues by IREBs delays and impedes research programs that could better inform us about chronic disease. RESULTS: The CPCSSN project's experience with gaining approval from IREBs highlights the difficulty of conducting pan-Canadian health surveillance and multicentre research. Inconsistent IREB approvals to waive explicit individual informed consent produced particular challenges for researchers. CONCLUSION: The CPCSSN experience highlights the need to develop a better process for researchers to obtain timely and consistent IREB approvals for multicentre surveillance and research. We suggest developing a specialized, national, centralized IREB responsible for approving multisite studies related to population health research.

Chronic constipation: an evidence-based review.

BACKGROUND: Chronic constipation is a common condition seen in family practice among the elderly and women. There is no consensus regarding its exact definition, and it may be interpreted differently by physicians and patients. Physicians prescribe various treatments, and patients often adopt different over-the-counter remedies. Chronic constipation is either caused by slow colonic transit or pelvic floor dysfunction, and treatment differs accordingly. METHODS: To update our knowledge of chronic constipation and its etiology and best-evidence treatment, information was synthesized from articles published in PubMed, EMBASE, and Cochrane Database of Systematic Reviews. Levels of evidence and recommendations were made according to the Strength of Recommendation taxonomy. RESULTS: The standard advice of increasing dietary fibers, fluids, and exercise for relieving chronic constipation will only benefit patients with true deficiency. Biofeedback works best for constipation caused by pelvic floor dysfunction. Pharmacological agents increase bulk or water content in the bowel lumen or aim to stimulate bowel movements. Novel classes of compounds have emerged for treating chronic constipation, with promising clinical trial data. Finally, the link between senna abuse and colon cancer remains unsupported. CONCLUSIONS: Chronic constipation should be managed according to its etiology and guided by the best evidence-based treatment.

Anti-diabetic and hypoglycaemic effects of Momordica charantia (bitter melon): a mini review.

It has been estimated that up to one-third of patients with diabetes mellitus use some form of complementary and alternative medicine. Momordica charantia (bitter melon) is a popular fruit used for the treatment of diabetes and related conditions amongst the indigenous populations of Asia, South America, India and East Africa. Abundant pre-clinical studies have documented the anti-diabetic and hypoglycaemic effects of M. charantia through various postulated mechanisms. However, clinical trial data with human subjects are limited and flawed by poor study design and low statistical power. The present article reviews the clinical data regarding the anti-diabetic potentials of M. charantia and calls for better-designed clinical trials to further elucidate its possible therapeutic effects.
